Adjustable desk assemblies and methods of using the same

Abstract

This disclosure describes improved adjustable desk assemblies. In certain embodiments, an adjustable desk assembly comprises an enclosure defining a U-shaped channel, a platform carriage received within the enclosure, and a height-adjustable extension member driven by a motorized actuator. The platform carriage integrates an upper platform and a lower platform and is movably coupled to guidance structures on the enclosure so that the carriage can translate vertically. In certain embodiments, the extension member is positioned above the platforms and extends downward to lower the carriage and retracts upward to raise the carriage, thereby permitting selectable heights suitable for standing use, chair-seated use, and floor-seated use. The assembly can further transition into a compacted stowage configuration in which the lower platform is rotated upward to form a box-like profile that reduces depth and frees floor area. Other embodiments are also disclosed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of, and priority to, U.S. Provisional Patent Application No. 63 / 761,160 filed on Feb. 21, 2025. The content of the above-identified application is herein incorporated by reference in its entiretyTECHNICAL FIELD

[0002] This disclosure relates to adjustable desk assemblies, and corresponding systems, methods, and apparatuses, that can be transitioned among various configurations, including seated and standing configurations. In certain embodiments, the systems, methods, and techniques described herein can be applied to arrange a working surface for floor sitting positions, chair sitting positions, and standing positions and / or to independently position one or multiple platforms along a post member to achieve ergonomic arrangements for users having various physical statures, heights, and proportions.BACKGROUND

[0003] Standard stationary desks typically consist of a fixed-height work surface supported by a frame or legs. The fixed-height work surface is typically the only surface that can be used for performing tasks and supporting equipment, such as computer monitors, keyboards, mouse devices, or the like. Stationary desks require individuals to remain seated while working, which may lead to prolonged periods of physical inactivity throughout a given day. Such extended periods of sitting can contribute to various health issues, including poor posture, back pain, reduced circulation, and increased risk of obesity and cardiovascular problems.

[0004] Additionally, stationary desks often do not accommodate the diverse ergonomic needs of different individuals. Individuals have unique characteristics, such as varying heights, sizes, torso lengths, arm lengths, and body types. Because stationary desks are typically designed with a single fixed-height work surface, the work surface often is not ergonomically suited for many individuals, potentially leading to discomfort and placing strains on various portions of the individuals’ bodies. This is especially true in scenarios where those individuals utilize the stationary desks for prolonged periods of time.

[0005] In recent years, various standing desks have been developed to enable users to work while standing, addressing some of the health concerns associated with prolonged sitting at stationary desks. However, these standing desks lack appropriate ergonomic designs, failing to adequately alleviate strain on users during extended periods of use. Like stationary desks, these standing desks typically include a single work surface that is relied on for supporting all computing equipment (e.g., mouse devices, keyboard devices, monitor devices, etc.).

[0006] Both traditional stationary desks and traditional standing desks fail to address the various strains placed on users in both seated and standing positions. These strains include eye and neck strain from improper monitor positioning, as well as wrist, hand, and shoulder strain from suboptimal keyboard and mouse placement. As mentioned above, most of these desks typically feature a single work surface, which limits their ability to accommodate a diverse range of ergonomic factors that can place strains on multiple body parts simultaneously. In cases where the desk includes a working surface that is adjustable in height, users often face a trade-off between aligning the surface for comfortable keyboard and mouse usage versus positioning monitors at an optimal eye level, making it challenging to achieve an ideal ergonomic setup for all components of the workstation and / or all user body parts.

[0007] Traditional stationary desks and traditional standing desks also do not accommodate individuals who prefer or need to work while seated on the ground. These chair-centric and elevated-surface designs generally presume a user positioned at chair height or standing height, and they are typically designed to provide a single work surface located well above the floor level. As a result, users who wish to sit on the ground lack appropriate means to place input devices, monitors, and other equipment at low positions that support neutral wrist, shoulder, and neck alignment while maintaining proper monitor viewing angles. In practice, such users must often improvise with ad hoc supports or use devices on the lap or at awkward angles, which can increase strain, reduce productivity, and undermine ergonomic consistency over time.

[0008] Working while seated on the ground can also provide what are commonly described as earthing or grounding benefits. Direct physical contact with the ground can allow the body to equalize electrically with the earth, a process that proponents suggest may help reduce stress, promote relaxation, and support more stable sleep and circadian rhythms. Many individuals report feeling calmer, more focused, and less tense when working on the ground, effects that may reflect a combination of factors, including direct contact with floor surfaces, increased body awareness, and subtle posture changes such as a naturally more upright head-and-neck position, gentle engagement of the core and spinal stabilizers, and periodic shifts among cross-legged, kneeling, or one-leg-extended postures that reduce static loading. As a generally low-risk practice, ground sitting may therefore offer both physical mobility advantages and potential nervous-system calming effects often associated with earthing.

[0009] Floor sitting can also promote more natural, dynamic movement compared to prolonged static chair sitting. Users typically and repeatedly transition among cross-legged, kneeling, one-leg-extended, and squatting postures, which can help keep joints lubricated, reduce stiffness, and discourage all-day slouching. Without a chair back to passively support the torso, the abdominal, oblique, and spinal stabilizing musculature may remain subtly engaged to maintain upright posture, potentially countering deconditioning that can occur during prolonged, supported sitting. Ground-level work can further encourage hip mobility by gently stretching the hips and groin, supporting external rotation, and counteracting tightness commonly associated with extended periods in chair-based positions.

[0010] Additionally, floor sitting can heighten posture awareness and encourage functional movement patterns during routine transitions. Users often perceive discomfort from poor alignment more quickly on the ground, prompting timely self-correction of lumbar collapse, shoulder rounding, or forward head posture. Frequent sit-to-stand and stand-to-sit movements engage the ankles, knees, hips, and gluteal musculature, which may help maintain functional strength and mobility across daily activities. For some users, ground-based work can also provide a mental reset by reducing office-coded cues, fostering a sense of grounding, and supporting deeper focus and creativity in certain tasks.

[0011] Accordingly, there is a need for an adjustable desk assembly that can be transitioned between chair-seated configurations, standing configurations, and ground-sitting configurations. There is also a need for an adjustable desk assembly that provides an ergonomic design that alleviates both eye and neck strains associated with viewing a monitor and strains associated with operating a keyboard, mouse device, or other equipment while arranged in the chair-seated configurations, standing configurations, and ground-sitting configurations.

[0012] The background description provided herein is to generally present the context of the disclosure. The materials described in this section are not prior art to the claims in this application and are not admitted to be prior art, or suggestions of the prior art, by inclusion in this section.BRIEF DESCRIPTION OF DRAWINGS

[0060] The following description sets forth exemplary aspects of the present disclosure. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure. Rather, the description also encompasses combinations and modifications to those exemplary aspects described herein.

[0061] This disclosure relates to adjustable desk assemblies, and corresponding systems, methods, and apparatuses. The drawings and corresponding description highlight various structural arrangements of the adjustable desk assemblies, each of which incorporates ergonomic features and mechanisms for adjusting the assembly among different operational configurations (e.g., including operational configurations that permit usage of the assemblies in standing, chair-seated, and / or floor-seated arrangements).

[0062] In certain embodiments, an adjustable desk assembly comprises an enclosure that is adapted to be coupled to a wall or surface and a height-adjustable platform carriage that is movably coupled to the interior of the enclosure. The enclosure can include a rear wall and a pair of side walls that are connected to form a U-channel that receives the platform carriage. The height-adjustable platform carriage can include at least two platforms, such as an upper platform and a lower platform. A platform adjustment assembly can be coupled to both the enclosure and the height-adjustable platform carriage and enables the platform carriage to move upward and downward among various operational configurations, including a standing configuration, chair-seated configuration, and / or floor-seated configuration, while maintaining a connection with the enclosure. In some exemplary configurations, the platform adjustment assembly can comprise one or more height-adjustable extension members (e.g., telescoping extension members) and one or more motorized or actuation components that cause the height-adjustable extension members to extend downward and / or retract upward to arrange the platform carriage in desired operational positions.

[0063] In certain embodiments, the structural configuration and arrangement of the adjustable desk assembly’s components permit the platform carriage to be lowered without obstructing the vertical path of the platform carriage, thereby permitting the platform carriage to be arranged for floor-seated usage. In this configuration, a height-adjustable extension member can be coupled to the platform carriage above the lower platform and coupled to a front surface of the rear wall of the enclosure. During operation, a motorized actuator causes a downward extension of the height-adjustable extension member, which operates to move the platform carriage downward along a vertical path. By positioning the motorized actuator and extension member above the lower platform of the platform carriage and extending the member downward to lower the carriage, the assembly can achieve very low working elevations without interference from hardware or components beneath the platforms, thereby enabling floor-seated arrangements.

[0064] Additionally, in certain embodiments, the adjustable desk assembly can be transitioned into a compacted, space-saving stowage configuration that arranges the adjustable desk assembly in a generally box-like profile. In this configuration, the motorized actuator can be activated to position the platform carriage such that the lower platform is substantially aligned with the lower edges of the enclosure side walls. The lower platform can then be translated outward along a tray structure and rotated upward approximately ninety degrees to an upright orientation adjacent to the open front of the enclosure. When stowed, the lower platform does not protrude outward and the combination of the rear wall and side walls with the upright lower platform defines a compact, box-shaped footprint that reduces depth and frees usable floor area.

[0065] In certain embodiments, an adjustable desk assembly includes at least two moveable platforms, such as an upper platform and a lower platform, that are both connected to a post member. The post member can be situated in a vertical arrangement, and each of the platforms can be coupled to the post member by a corresponding connection assembly. Each of the platforms also can be equipped with a platform adjustment assembly that can lock and unlock the platforms at various positions along the post member. The upper platform and lower platform can be independently positioned and secured in place along the post member, facilitating high levels of customization and permitting the platforms to be arranged in positions that simultaneously alleviate strains on different body parts during usage.

[0066] In certain embodiments, the adjustable desk assembly can represent or correspond to a sit-stand desk, which can be transitioned between a seating configuration, in which the platforms are arranged at positions that can be utilized when an individual is seated in a chair, and a standing configuration, in which the platforms are arranged at positions that can be utilized while the individual is standing. In some embodiments described herein, the adjustable desk assembly can further be transitioned to arrangements that facilitate floor-seated arrangements. The ability of the platforms to be precisely positioned along the post member permits the adjustable desk assembly to be arranged in many other configurations as well.

[0067] In some use cases, the lower platform of the adjustable desk assembly can be used to support a mouse device and / or a keyboard device, while the upper platform can be used to support a computer monitor device. Each platform can be precisely positioned to maximize ergonomic benefits and / or the user’s desired arrangement. For example, the upper platform can be positioned to precisely align a computer monitor directly with an individual's eye line, while the lower platform can be aligned to facilitate neutral positioning of the individual's hands or wrists. This ergonomic arrangement may help reduce neck strain by minimizing the need for the user to tilt their head up or down, while also decreasing the risk of repetitive stress injuries to the hands and wrists by promoting a more natural and comfortable typing position.

[0068] The configuration of the adjustable desk assemblies described herein can vary. In some embodiments, the adjustable desk assemblies can be integrated into a mounted configuration, which enables the adjustable desk assembly to be connected to mounting surfaces (e.g., walls and / or other surfaces). The mounted configuration of the adjustable desk assembly occupies no floor space, which can minimize the overall footprint required for installation and may be particularly beneficial in small rooms or environments with limited space. In other embodiments, the adjustable desk assembly can be integrated into a stationary structure, such as a frame-based desk or leg-based desk that rests on an underlying floor surface. For example, in certain embodiments, the integration of the adjustable desk assemblies can be viewed as retrofitting traditional stationary desk structures with the ergonomic benefits and adjustability features of the solutions described herein. In further embodiments, the adjustable desk assemblies can be integrated into a mobile configuration, in which the adjustable desk assemblies are integrated into movable desks and / or other movable structures. These movable desks or structures can include one or more wheels and / or other movement-enabling assemblies (e.g., sliders, rollers, casters, etc.) that enable them to be easily moved, positioned, or transported to desired locations. The adjustable desk assemblies can be integrated with many other configurations as well.

[0069] In certain embodiments, a platform adjustment assembly can be integrated into one or more of the platforms included in the adjustable desk assembly to enable the platforms to be positioned to desired locations and / or desired heights. The configurations of the platform adjustment assemblies can vary.

[0070] In some embodiments, the platform adjustment assembly can include a retractable pin assembly, such as a spring-loaded pin assembly, that engages the post member of the adjustable desk assembly. In a default position, the pin may be situated in an extended position that locks a platform in a position along the post member. One or more actuation members (e.g., such as levers, handles, sliders, buttons, etc.) integrated into the platform may be rotated or manipulated to disengage the pin from the post member to permit the platform to be moved upward and / or downward along the post member. The one or more actuation members also may be released and / or manipulated when the platform is positioned at a desired location, thereby re-extending the pin to its extended position and locking the platform in its position along the post member.

[0071] Additionally, or alternatively, the platform adjustment assembly can include one or more pulley assemblies that facilitate the repositioning of the platform. The configuration of the pulley assemblies can vary. In some cases, a pulley assembly can be used to engage or disengage a spring-loaded pin. In other embodiments, a pulley assembly can include a fixed pulley that engages a cable or wire, which enables the platform to be moved upward or downward along the length of a post member.

[0072] Additionally, or alternatively, the platform adjustment assembly can include other types of mechanical, electromechanical, and / or electronic assemblies to facilitate movement or repositioning of the platforms. For example, in some embodiments, the platform adjustment assembly can include a motorized actuator that drives an extension member to reposition a platform carriage that incorporates the upper and lower platform surfaces. As discussed below, many other arrangements of the platform adjustment assembly also are possible.

[0073] The adjustable desk assemblies described herein provide numerous advantages.

[0074] One advantage corresponds to the ability of the assemblies to be transitioned among various configurations, including a standing configuration, a char-seated configuration, a floor-seated configuration, and / or other configurations.

[0075] Another advantage associated with some embodiments described herein relates to positioning the height-adjustable extension member and motorized actuator above a platform carriage so that the actuator extends downward to lower the platform carriage, which avoids under-platform hardware interference and enables substantially lower working elevations suitable for floor-seated arrangements.

[0076] Another advantage associated with some embodiments described herein relates to the ability of the assembly to transition into a compact, space-saving configuration in which the lower platform is rotated upward to form a box-like profile that does not protrude outward, thereby reducing depth, freeing usable floor area, and providing convenient stowage. This compacted, spacing configuration is particularly useful to urban living, small apartments, and other space-limited environments.

[0077] Another advantage associated with some embodiments can be attributed to the structure of the assembly which includes at least two independently adjustable platforms, which, in some scenarios, can enable an individual to separately position a surface that supports a monitor and a surface that supports a keyboard, mouse device, or other items, thereby facilitating an ergonomic arrangement that helps to reduce strains placed on the individuals' neck, eyes, wrists, hands, shoulders, and back regions. Another advantage can be attributed to the granular degrees to which the platforms can be repositioned.

[0078] Many other advantages can be attributed to features associated with various configurations. For mounted adjustable desk assemblies, additional advantages can be attributed to the fact that the adjustable desk assemblies do not occupy any floor space, which can be particularly beneficial when the desk assemblies are utilized in small rooms or environments with limited space. Additional advantages can be attributed to embodiments in which the adjustable desk assemblies are configured to be mobile, which can enable an individual to move the desk assemblies among different rooms (e.g., to and from offices and conference rooms) and / or which can enable an individual to position the desk assemblies in desired locations (e.g., near windows or locations with aesthetically pleasing views). Additionally, in these mobile embodiments, the adjustable desk assemblies can be outfitted with wheels and / or other movement-enabling structures that permit them to be moved in a manner that avoids strains associated with lifting the desk assemblies. Additional advantages can be attributed to embodiments in which the adjustable desk assemblies are integrated into stationary structures, such as frame-based desk assemblies, leg-based desk assemblies, and / or other similar structures. The solutions described herein permit these stationary structures to be retrofitted or upgraded with adjustable platforms and increase the ergonomics of those structures.

[0079] Many other advantages and benefits can be attributed to the adjustable desk solutions described throughout this disclosure.

[0080] The embodiments described in this disclosure can be combined in various ways. Any aspect or feature that is described for one embodiment can be incorporated into any other embodiment mentioned in this disclosure. In some examples, any platform structure, adjustment mechanism, connection mechanism, and / or post member described for one embodiment can be integrated into any other embodiment described herein.

[0081] Additionally, various modifications can be applied to any of the embodiments described herein.

[0082] Some embodiments may describe the adjustable desk assemblies as having two platform structures, such as an upper platform and a lower platform. However, the adjustable desk assemblies can be configured with lesser numbers of platforms (e.g., a single platform) and / or greater numbers of platforms (e.g., three or more platforms). One or more of the platforms incorporated into the adjustable desk assemblies can be independently moveable (e.g., using one or more of the platform adjustment assemblies described herein or other types of adjustment assemblies) and / or can be non-moveable (e.g., fixed to a particular position along the post member and / or fixed to other structures included within the adjustable desk assemblies).

[0083] Additionally, while some embodiments may describe the adjustable desk assemblies as using particular types of platform adjustment mechanisms, it should be noted that any of the embodiments described herein can be adapted to include alternative platform adjustment mechanisms (including any of those described herein). Any of the adjustable desk assemblies described herein can be adapted to include mechanical, electromechanical, and / or electronic assemblies to facilitate movement or repositioning of the platforms. In some examples, the platform adjustment assemblies can include one or more ratchet assemblies, one or more rack and pinion assemblies, one or more lift assemblies, one or more lead screw assemblies, one or more chain and sprocket assemblies, one or more hydraulic assemblies, one or more pneumatic assemblies, one or more winch assemblies, one or more motor assemblies (e.g., one or more linear motor assemblies), one or more cam assemblies, one or more electronic adjustment assemblies, one or more voice-activated adjustment assemblies, and / or other types of assemblies.

[0084] The drawings illustrate various embodiments of the adjustable desk assemblies. However, the embodiments illustrated in the drawings are merely exemplary and should not be construed as limiting. Various modifications, alternatives, and variations may be implemented without departing from the spirit of the disclosure.

[0085] FIGS. 1A-1D illustrate an exemplary adjustable desk assembly 100 according to certain embodiments. FIG. 1A is a front perspective view of the adjustable desk assembly 100. FIG. 1B is a side view of the adjustable desk assembly 100. FIG. 1C is a front view of the adjustable desk assembly 100. FIG. 1D is a top plan view of the adjustable desk assembly 100.

[0086] In this embodiment, the adjustable desk assembly 100 is configured in a mountable configuration, which enables the adjustable desk assembly 100 to be connected to mounting surfaces, such as walls in offices, homes, classrooms, dormitories, or other buildings and / or other types of surfaces (e.g., partitions or dividers in office spaces, sides of filing cabinets or storage unit, structural columns or pillars, furniture). The mounted configuration of the adjustable desk assembly 100 offers significant advantages, as it does not occupy any floor space, which can be particularly beneficial when utilized in small rooms or environments with limited space. This compact design may allow for more efficient usage of existing space.

[0087] The adjustable desk assembly 100 includes an upper platform 110 (which also may be referred to as a "first platform 110" in this disclosure), a lower platform 120 (which also may be referred to as a "second platform 110" in this disclosure) situated beneath the upper platform 110, and a post member 130. Separate coupling assemblies 140 connect the upper platform 110 and the lower platform 120 to the post member 130. When connected to the post member 130, the upper platform 110 and lower platform 120 may be arranged parallel or substantially parallel to each other and arranged perpendicular or substantially perpendicular to the post member 130. Additionally, separate platform adjustment assemblies 150 incorporated into the upper platform 110 and lower platform 120 permit the upper platform 110 and lower platform 120 to be moved or repositioned along the post member 130 to desired positions and secured to the post member 130 at the desired positions. The upper platform 110 and lower platform 120 can be independently moveable (e.g., such that moving one of the platforms does not alter the position of the other platform). The adjustable desk assembly 100 further includes one or more mounting interfaces 160 that can be utilized to couple the adjustable desk assembly 100 to walls and / or other surfaces. Exemplary details of each of these components are described below.

[0088] In some exemplary use cases, the upper platform 110 can be utilized to support one or more monitor devices, such as LED (Light Emitting Diode) monitors, OLED (Organic Light Emitting Diode) displays, plasma screens, e-ink displays, DLP (Digital Light Processing) monitors, IPS (In-Plane Switching) panels, VA (Vertical Alignment) panels, holographic displays, projection monitors, and / or the like. Additionally, or alternatively, the upper platform 110 can be utilized to support one or more laptop devices, one or more tablet devices, one or more webcams, and / or one or more audio output devices (e.g., speaker devices).

[0089] In some exemplary use cases, the lower platform 120 can be utilized to support one or more one or more input devices and / or one or more audio output devices, such as keyboards, mouse devices, joysticks, microphones, speakers, and / or other devices. Additionally, or alternatively, the lower platform 120 can be utilized to support computing equipment such as hard drives, computer towers or chasses, power supplies, and / or the like.

[0090] In some cases, the lower platform 120 can be sized larger than the upper platform 110. For example, the length and / or width of the lower platform 120 can be larger or greater than the length or width of the upper platform 110. In other embodiments, the upper platform 110 and lower platform 120 may be the same size, or the upper platform 110 may be sized larger than the lower platform 120.

[0091] Both the upper platform 110 and lower platform 120 can be outfitted with one or more conduits (114, 124) which can be utilized to route wires from supported devices and equipment to one or more outlets or power supplies.

[0092] The configuration of the post member 130 can vary. In the example illustrated in FIGS. 1A-1D, the post member is arranged in a rectangle shape having four sides, such as a front surface 131, a rear surface 132 situated opposite the front surface 131, and a pair of side surfaces 133. In other embodiments, the post member 130 can be arranged in other shapes (e.g., shaped as a circular or semi-circular beam member and / or various other shapes). Regardless of its arrangement, a surface of the post member 130, such as the front surface 131, may be outfitted with a connection column 170. The connection column 170 can be adapted to engage or mate with adjustment assemblies 150 integrated into the upper platform 110 and lower platform 120, and may enable the upper platform 110 and lower platform 120 to be locked and secured in various positions along post member 130 (and, conversely, unlocked or disengaged for movement along with post member 130).

[0093] When the adjustable desk assembly 100 is assembled and / or installed on a wall or other mounting surface, the post member 130 can be arranged vertically or substantially vertically, e.g., such that the post member 130 is perpendicular or substantially perpendicular to an underlying floor surface and / or is parallel or substantially parallel to the wall or other mounting surface. The upper platform 110 and lower platform 120 can be arranged parallel to the underlying floor surface and perpendicular or substantially perpendicular to the post member 130.

[0094] In other embodiments (e.g., such as those illustrated in FIGS. 3-4), the post member 130 can be arranged vertically at an angle, e.g., such that the top end 136 of the post member 130 is connected to the mounting surface and the post extends downwardly and outwardly at a desired angle. In some examples, the angle formed between the post member 130 and the wall or mounting surface may be approximately 15, 30, 35, 45, 60, or 75 degrees. In such angled embodiments, a bottom support member may extend between a bottom end 137 of the post member and the wall to provide additional support, and obtuse angles may be formed between upper surfaces (111, 121) of the platforms and the post member 130.

[0095] One or more mounting interfaces 160 can be integrated into the post member 130, which facilitate the connection of the adjustable desk assembly 100 to a wall or other mounting surface. In the example illustrated in FIGS. 1A-1D, a first mounting interface 160 is incorporated at a top end 136 of the post member 130 and a second mounting interface 160 is incorporated at a bottom end 137 of the post member that is situated opposite the top end 136. However, the number and locations of the mounting interfaces 160 incorporated into the post member 130 can vary. For example, in other embodiments, one or more mounting interfaces 160 can be integrated along a middle segment of the post member 130.

[0096] The structures or configuration of the mounting interfaces 160 also can vary. In the example illustrated in FIGS. 1A-1D, the mounting interfaces 160 include brackets which comprise a first set of openings 165 for coupling the bracket to the post member (e.g., via screws, nails, bolts, or other fasteners) and a second set of openings 166 for coupling the bracket to a wall or surface (e.g., again, via screws, nails, bolts, or other fasteners). The mounting interfaces 160 can be constructed of metals, woods, plastics, polymers, and / or other materials.

[0097] In other embodiments, the mounting interfaces 160 additionally, or alternatively, can include mounting mechanisms other than brackets including, but not limited to, wall plates, French cleats, keyhole mounts, slotted channels, magnetic mounts, suction cup mounts, adhesive mounts, clamp-based mounts, tension rod mounts, hook-and-loop fastener systems, interlocking rail systems, pin-and-slot mechanisms, ball-and-socket joints, articulating arm mounts, telescoping pole mounts, spring-loaded mounts, quick-release mechanisms, dovetail joints, T-slot systems, toggle bolt assemblies, expansion bolt systems, threaded inserts, welded studs, riveted plates, snap-fit connectors, bayonet mounts, and / or other coupling mechanisms.

[0098] The configuration of the upper platform 110 and lower platform 120 can vary. In some embodiments, the upper platform 110 can include a top surface 111, a bottom surface 112 situated opposite the top surface 111, and one or more side surfaces 113 (e.g., four side surfaces 113 when the upper platform is configured in a rectangular or square shape). The top surface 111 can be substantially flat or planar, enabling the upper platform 110 to support various devices and equipment in a secure fashion. The bottom surface 112 can be adapted to receive, or can be integrated with, one or more of the platform adjustment assemblies 150 described herein. The side surface 113 situated adjacent to the post member 130 may represent a connecting surface, which is adapted to be connected to a coupling assembly 140 that connects the upper platform 110 to the post member 130. This connecting surface also may include portions of the platform adjustment mechanism 150 that facilitates repositioning of the upper platform 110 along the length of the post member 130.

[0099] In certain embodiments, the lower platform 120 can have the same or similar structure as the upper platform 110. For example, in some embodiments, the lower platform 120 can include a top surface 121, a bottom surface 122 situated opposite the top surface 121, and one or more side surfaces 123 (e.g., four side surfaces 123 when the upper platform is configured in a rectangular or square shape). The top surface 121 can be substantially flat or planar to support various devices and equipment in a secure fashion. The bottom surface 122 can be adapted to receive, or can be integrated with, one or more of the adjustment assemblies 150 described herein. A first side surface 123 situated adjacent to the post member 130 may represent a connecting surface, which is adapted to be connected to a coupling assembly 140 that connects the lower platform 120 to the post member 130 and which includes portions of an adjustment mechanism 150 that facilitates repositioning of the lower platform 120 along the length of the post member 130.

[0100] The size, shape, dimensions, and materials of the upper platform 110 and lower platform 120 can vary. In some embodiments, the upper platform 110 and lower platform 120 can be constructed from one or more wood materials. Additionally, or alternatively, the upper platform 110 and lower platform 120 can be constructed from one or more metals, one or more plastics, one or more polymers, and / or other materials. In the example illustrated in FIGS. 1A-1D, the upper platform 110 and lower platform 120 are arranged in rectangular shapes. However, the upper platform 110 and lower platform 120 may be arranged in other shapes (e.g., circular shapes, semi-circular shapes, triangular shapes, and / or other geometric shapes).

[0101] In some embodiments, the size or dimensions of the lower platform 120 can be greater than the size or dimensions of the upper platform 110. For example, the length of the lower platform's upper surface 121 may extend further outward from the post member 130 compared to the upper surface 111 of the upper platform 110 (e.g., as shown in FIG. 1B) and / or the width of the lower platform 120 also may be greater than the width of the upper platform 110 (e.g., as shown in FIG. 1C). This configuration can be beneficial for ergonomic and functional reasons. The larger size of the lower platform 120 provides increased surface area for accommodating a wider range of input devices and accessories, while also permitting the surface to be potentially used for notebooks, notes, writing device holders, etc. Additionally, the smaller or more compact surface area of the upper platform 110 can permit a monitor device or laptop to be positioned far enough away from a user, while it is also sufficiently sized to support the monitor device or laptop, which typically require less horizontal space compared to lateral arrangements of keyboard and mouse devices on the lower platform. Overall, this arrangement may help maintain a compact overall footprint for the adjustable desk assembly 100 while maximizing usable work area where it's most needed. The size difference between platforms may also contribute to a more organized, tiered workspace design, potentially improving user focus and productivity.

[0102] In some examples, the dimensions of the upper platform 110 can have a width of 20 inches (or in a range of 10-30 inches), a length of 10 inches (or in a range of 7-17 inches), and a depth or thickness of 0.5 inches (or in a range of 0.25-2.0 inches). In some examples, the dimensions of the lower platform 120 can have a width of 30 inches (or in a range of 20-40 inches), a length of 15 inches (or in a range of 5-25 inches), and a depth or thickness of 0.5 inches (or in a range of 0.25-2.0 inches). In some examples, the length of the lower platform 120 extending outwardly from the post member 130 can be approximately 5%, 10%, 15%, 20%, and / or 25% greater than the length of the upper platform 110. In some examples, the width of the lower platform 120 can be approximately 5%, 10%, 15%, 20%, and / or 25% greater than the length of the upper platform 110. However, the dimensions of both the upper platform 110 and the lower platform 120 can be varied and generally can include any width, length, or depth.

[0103] The size, shape, dimensions, and materials of the post member 130 can vary. In some embodiments, a base portion of the post member 130 can be constructed from one or more wood materials and the platform connection column 170 can be constructed from one or more metals. Additionally, or alternatively, the base portion and platform connection column 170 generally can be constructed from any material, and either can be constructed from one or more metals, one or more woods, one or more plastics, one or more polymers, and / or other materials. In the example illustrated in FIGS. 1A-1D, the post member 130 is generally arranged in a rectangular beam shape. However, the post member 130 may be arranged in other shapes as well.

[0104] Along similar lines, the size and dimensions of the post member 130 also can vary. In some examples, the post member 130 can have a width of 5 inches (or in a range of 2-10 inches), a length of 40 inches (or in a range of 20-60 inches), and a depth of 3 inches (or in a range of 1-5 inches). Again, the dimensions of post member 130 can be varied and generally can include any width, length, or depth.

[0105] The connection assemblies 140 can generally include any structure that is capable of connecting a platform (e.g., such as the upper platform 110 and / or lower platform 120) to the post member 130. The configuration of the connection assemblies 140 can vary.

[0106] FIGS. 2A-2B illustrate an example of a connection assembly 140 according to certain embodiments. FIG. 2A illustrates the connection assembly 140 without cover assemblies 149 attached, thereby exposing guide members 144 incorporated internally within the connection assembly 140. FIG. 2B illustrates the connection assembly 140 with the cover assemblies 149 attached, thereby concealing the guide members 144.

[0107] The connection assembly 140 includes, inter alia, a first platform receiving member 141 and a second platform receiving member 142 that are spaced apart from each other. The first platform receiving member 141 and the second platform receiving member 142 are situated parallel, or substantially parallel, to each other and the spacing between them forms a channel 143 for receiving a platform (e.g., for receiving either the upper platform 110 or lower platform 120). The channel 143 may have a height that corresponds to the thickness of a platform to be received in the channel 143 (e.g., and, in some cases, may have a height of 0.25, 0.5, 0.75, or 1 inch).

[0108] The edges of the first platform receiving member 141 and the second platform receiving member 142 located on the side of the connection assembly 140 that receives the platform may include one or more openings (141A, 142A), which are configured to receive fasteners (e.g., screws, nails, bolts, etc.) for coupling the platform to the connection assembly 140. In this example, the edges are each outfitted with four openings (141A, 142A), but any number of openings may be incorporated into the first platform receiving member 141 and the second platform receiving member 142.

[0109] The openings 141A included on the first platform receiving member 141 extend from the top surface of the first platform receiving member 141 through the bottom surface of the first platform receiving member 141. The openings 142A included on the second platform receiving member 142 extend from the top surface of the second platform receiving member 142 through the bottom surface of the second platform receiving member 142. The platform may be inserted into the channel 143 between the bottom surface of the first platform receiving member 141 and the top surface of the second platform receiving member 142.

[0110] The openings 141A in the first platform receiving member 141 are aligned directly above the openings 142A included on the second platform receiving member 142. As shown in FIGS. 2C-2D, corresponding openings 115 also may be integrated into the platforms (that is, the upper platform 110 and lower platform 120) at or near the edge of the platforms that are connected to the post member 130, which also extend through the top and bottom surfaces of the platforms. The openings 115 are aligned with the openings (141A, 142A) in the first platform receiving member 141 and the second platform receiving member 142, thereby permitting insertion of the fasteners through the holes (141A, 142A, 115) for coupling and securing the platform to the connection assembly 140.

[0111] A central channel 145 extends through the entirety of the connection assembly 140, which is designed to accommodate and receive the post member 130. The central channel 145 can be sized or dimensioned to receive the post member 130 (e.g., may be sized slightly larger or wider than the post member 130).

[0112] One or more guide members 144 may be incorporated into the connection assembly 140 to assist the connection assembly 140 with smoothly moving along with the post member 130 when a connected platform is being repositioned, or moved upward or downward, along the post member 130. In this example, the guide members 144 correspond to roller members, which may include cylindrical roller structures connected by mounting members 146. The roller members can be adapted to rotate about a central axis or mounting axis extending laterally or horizontally through their centers. The top surface of the first platform receiving member 141 includes four roller members arranged in a rectangular shape around the central channel 145, and the bottom surface of the second platform receiving member 142 likewise includes four roller members arranged in a rectangular shape around the central channel 145. Other types and arrangements of guide members 144 may be incorporated into the connection assembly 140 to guide or assist movements along the post member 130.

[0113] One or more cover assemblies 149 may be applied to conceal the guide members 144. For example, a first cover assembly 149 may be connected to the top surface of the first platform receiving member 141 to conceal the guide members 144 located on an upper portion of the connection assembly 140, while a second cover assembly 149 may be connected to the bottom surface of the second platform receiving member 142 to conceal the guide members 144 located on a bottom portion of the connection assembly 140.

[0114] The cover assemblies 149 can serve several purposes. Firstly, they can conceal the exposed portions of the guide members 144, thereby providing a safety feature to prevent user injuries (such as fingers becoming caught in the rollers). Additionally, the cover assemblies 149 can protect the guide members 144 from potential damage and / or mitigate the ingress of dust or contaminants that could impair the operation of the guide members 144.

[0115] While concealing the exposed portions of the guide members 144 (which, in some cases, may include roller members as mentioned above), the cover assemblies 149 do not extend to, or cover, the portions of the roller members which face inwardly towards the central channel 145, thereby allowing the guide members 144 to engage the post member 130 and assist with moving the connected platform along the post member 130.

[0116] Numerous modifications can be incorporated into the connection assemblies illustrated in FIGS. 2A-2B. Amongst other things, the size, shape, and dimensions of the central channel 145 can be adapted to receive post members 130 of varying sizes, shapes, and dimensions. Likewise, the size, shape, and dimensions of the channel 143 formed between the first platform receiving member 141 and the second platform receiving member 142 can be adapted to accommodate platforms of varying sizes, shapes, and dimensions. Further, fewer or greater numbers of guide members 144 may be incorporated into the connection assembly 140. Additionally, the connection assembly 140 may incorporate other types of movement-facilitating structures other than, or in addition to, the roller members shown in the figures. In some examples, the guide members 144 additionally, or alternatively, can include one or more of the following: sliders, ball bearings, linear bearings, bushings, glide pads, low-friction coatings or materials, magnetic levitation systems, track systems, guide rails, linear actuators, rack and pinion systems, belt drives, chain drives, cable systems, hydraulic or pneumatic cylinders, spring-loaded mechanisms, cam followers, roller chains, linear motion guides, recirculating ball bearings, crossed roller bearings, and / or lubricating materials or coatings. Many other variations of the connection assembly 140 also are contemplated.

[0117] The connection assembly 140 and / or its various components can be constructed of any appropriate material. In some embodiments, the connection assembly 140 and / or its components can be constructed of durable or sturdy materials, such as metals, that are designed to accommodate the wear and tear associated with continuously moving or adjusting the platforms. In some embodiments, the connection assembly 140 and / or its components additionally, or alternatively, can be constructed of one or more woods, one or more plastics, one or more polymers, and / or other materials.

[0118] FIGS. 2C-2D illustrate an exemplary configuration of an upper platform 110 according to certain embodiments. The same or similar configuration can be applied to the lower platform 120 (although, in some cases, the lower platform 120 may have varied length and width dimensions as mentioned above).

[0119] In this example, the upper platform 110 is arranged in a substantially rectangular shape that is defined by four side walls 113. One of the side walls 113 that connects the platform to the post member 130 includes a portion of a connecting surface 113A, which is adapted to receive a coupling assembly 140 that connects the platform to the post member 130. Specifically, a U-channel 116 is integrated into the connecting surface 113A, which comprises a first edge 116A, second edge 116B, and third edge 116C. The first edge 116A and second edge 116B extend outwardly from the side wall 113 and are connected by a third edge 116C.

[0120] When the connection assembly 140 is connected to the platform, the third edge 116C can be received in the channel 143 of the connection assembly 140, and the first edge 116A and second edge 116B mate with, or extend around, a central portion of the connection assembly 140 that forms the central channel 145. The first platform receiving member 141 and second platform receiving member 142 of the connection assembly 140 extend past the edge of the side wall 113, permitting the openings (141A, 142A) included on the first platform receiving member 141 and second platform receiving member 142 to align with the openings 115 on the connecting surface 113A.

[0121] The bottom surface 112 (as shown in FIG. 2D) of the platform can include conduits 117 configured to receive various portions of an adjustment assembly 150 (e.g., such as the one illustrated in FIGS. 2E-2G). The conduits 117 can correspond to engravings, recessed surfaces, and / or other structures that are fitted or adapted to accommodate the adjustment assembly 150. In this example, a first conduit 117A is designed to receive a retractable pin assembly (e.g., such as retractable pin assembly 153 in FIGS. 2E-2F), a pair of second conduits 117B is designed to receive wire members (e.g., such as wire members 152 in FIGS. 2E-2F), and a pair of third conduits 117C are adapted to receive actuation members (e.g., such as actuation members 151 in FIGS. 2E-2F) of the platform adjustment assembly 150.

[0122] Recessed surfaces 118 are integrated into two of the side walls 113 of the platform. These recessed surfaces 118 can be strategically located adjacent to each of the third conduits 117C that receive the actuation members of the platform adjustment assembly 150, enabling users to easily locate and identify the actuation members without the need to bend or kneel. The recessed surfaces 118 serve as tactile indicators which can provide a convenient means for users to quickly find and engage the actuation members by touch alone (e.g., without even having to look downwards or underneath the platforms).

[0123] Numerous modifications can be incorporated into the platform surfaces illustrated in FIGS. 2C-2D. Amongst other things, the configuration of the bottom surface 112 can be adapted to accommodate various arrangements of the platform adjustment assemblies 150, including different layouts, sizes, or types of conduits for receiving or housing varying components. Similarly, the connecting surface 113A can be modified to interface with alternative designs of the connection assemblies 140, potentially altering the shape, size, or configuration of the U-channel 116 or the placement of openings 115. The number, size, shape, and positioning of the recessed surfaces 118 may also be varied to suit different ergonomic needs or aesthetic preferences. Additionally, the overall dimensions, shape, and material composition of the platform can be adjusted to meet specific requirements or use cases.

[0124] FIGS. 2E-2G illustrate an exemplary platform adjustment assembly 150 according to certain embodiments. FIG. 2E illustrates details of an exemplary retractable pin assembly 153 included therein. FIG. 2F illustrates the exemplary retractable pin assembly 153 connected to wire members 152. FIG. 2G illustrates platform adjustment assembly 150 integrated into a lower surface of a platform. The platform adjustment assembly 150 may be integrated into both the upper platform 110 and lower platform 120 described herein in the same or similar manner illustrated in FIG. 2G.

[0125] In this embodiment, the platform adjustment assembly 150 comprises a retractable pin assembly 153, which includes a locking pin 155 that is adapted to lock or secure a platform to various receiving portions of the platform connection column 170 included on the post member 130. For example, the locking pin 155 may be configured to transition between an extended position that engages the connection column 170 and secures a connected platform in place and a retracted position that disengages the connection column 170 and permits the connected platform to be moved. The platform adjustment assembly 150 further comprises a pair of wire members 152 that couple the retractable pin assembly 153 to a pair of actuation members 151.

[0126] In operation, when a user desires to adjust or reposition a platform, the user can engage or manipulate the actuation members 151 to retract the locking pin 155 from one of the receiving portions included on the platform connection column 170. While the locking pin 155 is retracted, the platform can be moved upward and / or downward along the post member 130 to a desired position. The actuation members 151 can be released or adjusted to cause the locking pin 155 to reengage the platform connection column 170, thereby securing the platform to the post member 130.

[0127] The retractable pin assembly 153 comprises a frame 156 that mounts or couples together a spring member 154, the locking pin 155, and the wire members 152. Each wire member 152 includes a first end that is coupled to an actuation member 151 and a second end that is coupled to the spring member 154. One end of the spring member 154 is coupled to the locking pin 155 and the opposite end is coupled to the pair of wire members 152. One or both of the actuation members 151 may be engaged or manipulated (e.g., in some cases, rotated, turned, or twisted) to retract the locking pin 155. That is, engaging or manipulating one or more of the actuation members 151 can retract or pull on the wire members 152, which, in turn, can extend or pull on the spring member 154, thereby causing the locking pin 155 to be retracted.

[0128] In certain embodiments, the platform adjustment assembly 150 incorporates a spring-loaded pin mechanism. In a default state, the spring member 154 is extended to arrange the locking pin 155 in a forward position, which causes the locking pin 155 to engage a receiving portion on the platform connection column 170 and lock the platform in position. When the spring member 154 is retracted, such as when it is pulled or extended by a force from the wire members 152, the locking pin 155 is retracted from the receiving portion on the platform connection column 170, allowing the platform to be moved or repositioned.

[0129] The wire members 152 can correspond to cables, cords, wires, and / or similar types of connectors. The spring member 154 can include a coiled or helical structure that is deformable such that it can be transitioned between an extended state and a compressed state. Additionally, the ends of the spring member 154 may include connection portions that enable the spring member 154 to be directly or indirectly coupled to the wire members 152 and the locking pin 155. The frame 156 can include a structure that is substantially flat or planar and which includes connection points 152A for receiving and / or coupling the wire members 152. Additionally, the frame 156 may include connection points for receiving, mounting, and / or coupling the locking pin 155 and spring member 154.

[0130] In the exemplary embodiment illustrated in FIG. 2G, the actuation members 151 correspond to rotatable levers. The levers may be rotated between a first position that causes the locking pin 155 to retract and a second position in which the locking pin 155 is extended. The range of motion of the levers may be defined by the size or width of the third conduit 117C included on the bottom surface of the platform.

[0131] In certain embodiments, the wire members 152 and retractable pin assembly 153 (including the spring member 154, locking pin 155, and frame 156) may be constructed of one or more metals. These components can be constructed of other suitable materials as well (e.g., plastics, polymers, woods, fibers, etc.).

[0132] Numerous variations can be incorporated into the platform adjustment assembly 150 illustrated in FIGS. 2E-2G. In one example, the platform adjustment assembly 150 may include a single wire member 152 connected to a single actuation member 151, which can be manipulated to retract the locking pin 155. In this variation, the single actuation member 151 may be designed to provide sufficient force through the single wire member to overcome the spring tension and retract the locking pin when adjusted. In some examples, this single actuation member 151 may be centrally located on the bottom surface of the platform (e.g., at or near the edge opposite where the locking pin 155 is located).

[0133] In other variations, the platform adjustment assembly 150 may incorporate different types of actuation members 151, such as knobs, dials, push buttons, sliding switches, electronic controls, touch-sensitive controls, and / or other structures or devices. Additionally, any of the actuation members 151 may be positioned at various locations on the platform, including on the top surface, bottom surface, and / or side surfaces of the platform.

[0134] In further variations, the platform adjustment assembly 150 may incorporate different types of assemblies or mechanisms for securing the platform to the connection column 170 and / or post member 130. For example, the assembly may utilize electromagnetic solenoids, hydraulic or pneumatic cylinders, motorized linear actuators, cam mechanisms, rack and pinion systems, belt-driven assemblies, pulley-driven assemblies, and / or other mechanisms to retract / extend the locking pin 155 and / or adjust the position of the platform in other ways. Additionally, in some embodiments, the platform adjustment assembly 150 may include a more simplistic configuration that permits a user to lift or adjust the platforms (e.g., by manually inserting the locking pin 155 into receiving portions of the post member 130 and / or connection column 170 or connecting the platform to the post member 130 in other ways. Other portions of this disclosure describe some of these alternative platform adjustment assemblies 150.

[0135] FIGS. 2H and 2I illustrate an exemplary configuration of a post member 130 and connection column 170 according to certain embodiments. In this embodiment, the post member 130 is arranged in a rectangular configuration and includes a front surface 131, a rear surface 132, and a pair of side surfaces 133. In certain embodiments, the post member may be formed of one or more wood materials and the platform connection column 170 may be formed of one or more metal materials. However, both the post member 130 and platform connection column 170 can be formed of any suitable materials, e.g., one or more woods, one or more metals, one or more plastics, one or more polymers, and / or other suitable materials.

[0136] A channel 134 is located on the front surface 131 of the post member 130, which extends a majority of the entire length of the front surface 131 (e.g., a majority of the length between the top end 136 and bottom end 137 of the post member 130). In some embodiments, the channel 134 may be formed by applying etching, engraving, carving, and / or laser cutting techniques on the post member 130.

[0137] The channel 134 is adapted to receive and connect to a platform connection column 170. The platform connection column 170 may be coupled to the channel 134 of the post member 130 using various techniques. In some examples, the channel 134 may include one or more first openings and the platform connection column 170 also may include one or more second openings. The one or more second openings may be aligned with the one or more first openings when the platform connection column 170 is placed or inserted into the channel 134. When inserted into the channel 134, one or more hardware connectors (e.g., screws, nails, bolts, etc.) may be inserted through each of the one or more first openings and one or more second openings to couple the platform connection column 170 to the channel 134.

[0138] Other coupling mechanisms may be used to connect the platform connection column 170 to the post member 130, and the particular coupling mechanisms employed can vary based on the materials that are used to form the post member 130 and / or platform connection column 170. In some examples, these mechanisms may include welding, e.g., where the platform connection column 170 is fused directly to the post member 130 using heat and pressure. Adhesive bonding may also be employed, e.g., utilizing high-strength industrial adhesives to secure the components together. In some cases, interlocking mechanisms, such as dovetail joints and / or tongue-and-groove connections, may be incorporated into the design of both the platform connection column 170 and the post member 130, allowing them to slot together securely. Magnetic coupling mechanisms also may be used in certain implementations, e.g., with strong magnets embedded in both components to hold them in place. Additionally, snap-fit connections also may be used, e.g., where flexible protrusions on one component engage with corresponding recesses on the other, which may provide a quick and tool-free assembly method. In further examples, a combination of these coupling mechanisms may be employed to ensure a robust and secure connection between the platform connection column 170 and the post member 130.

[0139] In some embodiments, the platform connection column 170 may be directly integrated with the post member 130. For instance, the post member 130 may be manufactured to include the platform connection column 170 as a single, unified structure. This integration can be achieved through various manufacturing processes. In some cases, the post member 130 may be carved, engraved, or laser cut to form the platform connection column 170 directly within its structure. Alternatively, injection molding techniques may be employed to form the connection column 170 directly into the post member 130 during the manufacturing process.

[0140] In some embodiments (e.g., such as when the adjustable desk assembly is arranged in a mounted configuration), the post member 130 also can include one or more connectors 138 for coupling one or more mounting interfaces 160 to the post member 130. In the example of FIG. 2H, the side surfaces 133 of the post member 130 include a plurality of connectors (e.g., openings that receive screws or other hardware connectors) at both top end 136 and bottom end 137 of the post member 130.

[0141] The types of connectors 138 incorporated into the post member 130, as well as the locations of the connectors 138, may vary. In some cases, the connectors 138 may include threaded holes for receiving screws or bolts, allowing for secure attachment of mounting interfaces 160. Additionally, or alternatively, the connectors 138 may comprise keyhole slots, e.g., enabling quick installation and removal of mounting hardware. Additionally, or alternatively, the connectors 138 may be designed as protruding studs or pins that engage with corresponding openings in the mounting interfaces 160. Regarding locations, while the example in FIG. 2H shows connectors 138 at both the top end 136 and bottom end 137 of the post member 130, other configurations are possible. For instance, additional connectors 138 may be positioned along the length of the post member 130 (e.g., on the front surface 131, rear surface 132, side surfaces 133, top surface, and / or bottom surface) to provide multiple mounting options or to distribute the load more evenly. In some embodiments, the connectors 138 may be arranged in patterns or arrays to accommodate various sizes and types of mounting interfaces 160. The specific arrangement and type of connectors 138 may be selected based on factors such as the intended use, load-bearing requirements, and ease of assembly or disassembly of the adjustable desk assembly.

[0142] FIG. 2I is an exploded view that illustrates additional details of an exemplary platform connection column 170. In this example, the platform connection column 170 is arranged in a stepped configuration 175 and comprises a vertical member 171 that is connected to a stepped post member 172. The vertical member 171 may be connected to the stepped post member 172 using any appropriate coupling mechanism (e.g., by fusing, welding, adhesives, hardware connectors, etc.)

[0143] The stepped post member 172 comprises a plurality of vertically repeating step members 174, each of which includes a shelf portion 176 that is arranged substantially perpendicular with respect to the vertical member 171 and a wall 177 that extends downwardly from the shelf portion 176 and inwardly towards the vertical member 171. For each step member 174, a bottom section of each wall 177 connects to a shelf portion 176 of an underlying step member 174.

[0144] The stepped configuration 175 of the platform connection column 170 may provide multiple engagement portions 173 for connecting the platforms (e.g., the upper platform 110 and lower platform 120) along the length of the post member 130. In some examples, the engagement portions 173 may comprise openings or slots that are adapted to receive a locking pin 155 of a platform adjustment assembly 150, and connecting the locking pin 155 to an engagement portion 173 can permit the platform to be secured to the post member 130. In some examples, a platform can be rested on the shelf portion 176 at a desired location and the locking pin 155 can be connected to an engagement portion 173 located beneath the shelf portion 176 (e.g., as shown in FIG. 2N). This connection formed between the locking pin 155 and the corresponding engagement portion 173 can secure the platform in place at a location desired by the user. These engagement portions 173 may be formed or integrated along the walls 177 (e.g., central portions of the walls 177) connecting to upper and lower shelve portions 176.

[0145] As shown, the stepped configuration 175 includes a series of vertically spaced protrusions or ledges extending outward with respect to the vertical member 171. In some embodiments, the various step members 174 and / or engagement portions 173 may be uniformly spaced or varied in their spacing to accommodate different adjustment increments. The stepped configuration 175 may allow for precise and secure positioning of the platforms at various heights. This arrangement may enable users to easily adjust the height of each platform by moving it to a different step and re-engaging the locking mechanism. The stepped configuration 175 may also contribute to the overall stability of the adjustable desk assembly by providing multiple load-bearing surfaces along the length of the post member 130.

[0146] The structure or configuration of the platform connection column 170 can be varied in many ways to accommodate different design requirements and functionalities. In some embodiments, the platform connection column 170 may not include a stepped configuration, but instead may feature a smooth, continuous surface with regularly spaced engagement portions 173. These engagement portions 173 may be in the form of holes, slots, or protrusions that interact with the platform adjustment assemblies 150. Alternatively, the platform connection column 170 may incorporate a rack-and-pinion system, where a toothed rack along the column engages with gears on the platforms for adjustment. In other variations, the column may feature a series of evenly spaced notches or grooves that work in conjunction with spring-loaded pins or hooks on the platforms. Some implementations may utilize a magnetic system, where the column includes a series of magnetic strips or points that correspond to complementary magnetic elements on the platforms. Additionally, the platform connection column 170 may be designed with a pneumatic or hydraulic system integrated within, allowing for smooth, pressure-assisted adjustments of the platforms. The platform connection column 170 may also be configured to incorporate electronic control systems, enabling users to adjust the platforms along the post member using electronic interfaces. In such implementations, the column may include integrated motors, actuators, and / or other electromechanical components that work in conjunction with user-operated controls, allowing for precise, automated adjustments of the platform positions without manual effort. Many other variations also are possible.

[0147] FIGS. 1A-1D illustrate the adjustable desk assembly 100 in a mounted configuration which includes the exemplary connection assembly 140 illustrated in FIGS. 2A-2B, the exemplary platform structural arrangement in FIGS. 2C-2D, the exemplary platform adjustment assembly 150 illustrated in FIGS. 2E-2G, and the exemplary post member 130 configuration illustrated in FIGS. 2H-2I.

[0148] FIGS. 2J-2N provide additional views of the exemplary adjustable desk assembly 100 illustrated in FIGS. 1A-1D, particularly highlighting the implementation of the platform adjustment assemblies 150 into each of the upper platform 110 and lower platform 120. As shown in FIGS. 2J and 2L, cover structures may be attached to the bottom surfaces (112, 122) of the platforms to conceal various components (e.g., the wire members 152 and retractable pin assembly 153) of the platform adjustment assemblies 150. In addition to providing aesthetic improvements, these cover structures may protect these components from damage and / or tampering. Additionally, FIGS. 2K and 2M illustrate arrangements of the connection assemblies 140 and platform adjustment assemblies 150 when the platform is removed. FIG. 2N provides a cross-sectional view demonstrating how a locking pin 155 can be inserted into an engagement portion included on the platform connection column 170. Moreover, the guide members 144 (in this example, roller members) included in the connection assembly 140 contact the front surface 131 and rear surface 132 of the post member 130, and can assist with guiding the platform upwardly and downwardly along the post member 130 when the locking pin 155 is disengaged.

[0149] It should be understood that any or all of the components illustrated in the embodiments shown in FIGS. 1A-1D and 2J-2M can be adapted or modified, and alternative configurations or arrangements can be utilized to implement the connection assemblies 140, platform structures, platform adjustment assemblies 150, and / or post member 130.

[0150] FIGS. 3 and 4 illustrate another embodiment of an adjustable desk assembly 100. This embodiment includes an alternative platform adjustment assembly 150, an alternative platform structural configuration, an alternative connection assembly 140, and an alternative configuration for the post member 130. FIG. 3 is a perspective view of the adjustable desk assembly 100. FIG. 4 is a view of the adjustable desk assembly 100 with the platforms removed, which highlights additional details of the alternative platform adjustment assembly 150.

[0151] In this embodiment of the adjustable desk assembly 100, the platform adjustment mechanism 150 incorporates a pulley-based adjustment assembly 150A. The pulley-based adjustment assembly 150A comprises at least one actuation member 151, at least one wire member 152, at least one pulley wheel 153A, and a locking pin 155.

[0152] The actuation member 151 is connected to one end of a wire member 152 and an opposite end of the wire member 152 is connected to the locking pin 155. Additionally, a central portion of the wire member 152 is received in a groove or channel of the pulley wheel 153A. The actuation member 151 in this example is shown as a lever or handle that can be manipulated (e.g., pulled or pushed) to move laterally or sideways. Engaging the actuation member 151, such as pulling the lever or handle outward towards the side edge of a platform, can cause the wire to be pulled outward, which in turn can disengage the locking pin 155 from an engagement portion 173 of the platform connection column 170, thereby allowing the platform to be moved along the post member 130. For example, when the actuation member 151 is engaged causing a pulling force on the wire member, the pulley wheel 153A can rotate and the movement of the wire member 152 can cause the locking pin 155 to be retracted backward.

[0153] The structural configuration of the upper platform 110 and lower platform 120 are adapted to accommodate the pulley-based adjustment assembly 150A. A conduit 117D included on the bottom surfaces (112, 122) of the platform receives the actuation member 151 and provides space for permitting the movement of the actuation member 151. Additionally, a pulley wheel mount 119 may be incorporated into the platforms to secure the pulley wheel 153A in a position (e.g., such as a position that aligns the wire member 152 included in the groove of the pulley wheel 153A along a central axis with the locations of the locking pin 155 and platform connection column 170).

[0154] In this exemplary embodiment, the connection assembly 140 for each platform includes a pair of support members 147. The support members 147 can be designed to slide up and down along the side walls 133 of the post member 130 and may extend around the rear surface 132 of the post member 130 to couple the platforms to the post member 130. An upper portion of the support members 147 can be connected to the bottom surfaces (112, 122) of the platforms (e.g., using hardware connectors and / or other connection schemes).

[0155] The post member 130 is arranged at an angle, such that the bottom end 137 of the post member 130 is situated outward towards the front of the adjustable desk assembly 100, while the top end 136 of the post member 130 is situated in a more rearward position. The top portion of the post member 130 also is connected to a back wall 139, which provides support for the post member 130. An acute angle is formed between the rear surface 132 of the post member 130 and the front surface of the back wall 139. In some embodiments, the back wall 139 may be arranged substantially vertically (e.g., approximately one-hundred and eight degrees with respect to an underlying floor surface). In other embodiments, the back wall 139 can be arranged vertically but offset at an angle, such as to form an A-shape with the post member 130.

[0156] The adjustable desk assembly 100 illustrated in FIGS. 3 and 4 can be arranged in a mounted configuration which permits the adjustable desk assembly 100 to be mounted to a wall or other surface. For example, one or more mounting interfaces 160 can be incorporated into the back wall 139 and / or other portions of the adjustable desk assembly 100. The adjustable desk assembly 100 illustrated in FIGS. 3 and 4 also can be incorporated into stationary and / or mobile desk configurations described herein.

[0157] FIGS. 5A-5B disclose another embodiment of an adjustable desk assembly 100. In this embodiment, the adjustable desk assembly 100 is arranged in an ultra-compact configuration, which can be particularly beneficial when installed in environments having limited available space.

[0158] In this exemplary embodiment, the post member 130 is connected to a post adjustment assembly 510, which enables the post member 130 to be moved upward and downward to different positions. Various types of post adjustment assemblies 510 can be incorporated into the adjustable desk assembly 100 to facilitate repositioning of the post member 130.

[0159] In this example, the post adjustment assembly 510 comprises a housing 511 and an extendible shaft member 512 that is received inside the housing 511. In some embodiments, a rear surface of the housing 511 (or other portion of the housing 511) may include one or more mounting interfaces 160 that permit the adjustable desk assembly 100 to be coupled to a mounting surface, such as a wall. The interior portion of the housing 511 can include a channel or corridor that receives a lower portion of the shaft member 512, and a top portion of the shaft member 512, which is coupled to the post member 130, may extend above the housing 511. The shaft member 512 is adapted to be vertically extended and / or moved upwardly and downwardly inside the channel or corridor of the housing 511. In certain embodiments, a portion of the shaft member 512 may be movably coupled to the housing 511 and, in other embodiments, there may be no direct coupling of the shaft member 512 to the housing 511.

[0160] A front surface of the post adjustment assembly 510 comprises a plurality of post connection interfaces 514 spaced vertically from each other along the front surface (e.g., spaced in predetermined intervals). Each of the post connection interfaces 514 is adapted to receive a connector 513 incorporated into a rear surface 132 of post member 130. In this example, the connector 513 comprises a protrusion or extension that extends outwardly from the rear surface 132 (e.g., at an angle that is perpendicular or approximately perpendicular with respect to the rear surface 132), and the post connection interfaces 514 include openings or recesses that are configured to receive the protrusion or extension on the post member 130. However, other types of connection schemes can be incorporated to couple the post member to the housing 511.

[0161] In certain embodiments, a top portion of the shaft member 512 can be coupled to the rear surface 132 of the post member 130 at or near a top portion of the post member 130. One or more connectors 515 (e.g., hardware connectors and / or any other type of connectors mentioned in this disclosure) can operate to couple the shaft member 512 to the post member 130.

[0162] In operation, an individual may reposition the height of the post member 130 along the housing 511 and, when the post member 130 is arranged at a desired position, the connector 513 included on the rear surface 132 of the post member 130 may be inserted into a nearest post connection interface 514 to secure the post member 130 at the desired height or location. Additionally, the connection between the top portion of the shaft member 512 and the post member 130 can ensure that the post member 130 does not become disengaged or disconnected from the housing 511 or adjustable desk assembly 100.

[0163] In the exemplary embodiment in FIGS. 5A-5B, the adjustability of the post member 130 permits the user to arrange the upper platform 110 and lower platform 120 of the adjustable desk assembly 100 to desired heights or positions. The arrangements or positioning of the platforms can be further customized by arranging or positioning the platforms along the platform connection column 170 of the post member 130.

[0164] In this embodiment, the post member 130 and platform connection column 170 may be formed as a single, integrated unit (e.g., formed in a unitary arrangement). The platform connection column 170 is formed on or extends outwardly from the front surface of the post member 130.

[0165] The platform connection column 170 comprises a plurality of repeating step members 174, each of which includes a shelf portion 176 and a wall 177 that extends downwardly from the shelf portion 176 and inwardly towards the direction of the post member 130. In this embodiment, the step members 174 are arranged in a cascading configuration 179A, with each successive step extending further outward from the post member 130. The topmost step member 174 is positioned closest to the post member 130, while each subsequent step protrudes incrementally further outward. As a result, the bottommost step member 174 extends the farthest from the post member 130. This cascading configuration 179A can be advantageous as it provides certain ergonomic benefits, which can be attributed to offsetting or placing the upper platform 110 further away from the user (e.g., which, in some uses, can position a monitor device in a more suitable location).

[0166] Recesses 178 are formed between each of the shelf portions 176 and / or each of the step members 174. The platforms (such as the upper platform 110 and / or lower platform 120) can be manually positioned into the recesses 178 to arrange the platforms at desired heights. When the platforms are inserted into the recesses 178 at desired heights, the platforms can be supported, at least in part, by the corresponding shelf portion 176 (which may include a flat or planar surface for supporting the platforms).

[0167] Additionally, in this exemplary embodiment, the upper platform 110 is configured with a connecting surface 113A that enables the platform to be coupled to each of the various step members 174 included on the pair of platform connection columns 170. For example, the connecting surface 113A may comprise one or more openings or conduits that extend through the platforms, and which are adapted to receive an upper portion of each step member 174. In some embodiments, an opening or conduit may be sized to receive a shelf portion 176 of each step and, when the platform is connected to a desired step member 174, the shelf portion 176 can extend into or through the opening or conduit included on the platform to facilitate connection of the platform. In some cases, one or more connection assemblies 140 also can be utilized to lock or secure the platforms at desired locations.

[0168] In certain embodiments, one or more of the platforms (e.g., the lower platform 120) can be integrated or formed in a unity fashion with one of the step members 174 (e.g., such as the lowest step member 174). While this stationary or non-movable platform may not be repositioned along the platform connection column 170, the adjustability of the post adjustment assembly 510 enables the position or height of the platform to be adjusted to desired positions. In other embodiments, the lower platform 120 can include the same or similar connecting surface 113A shown on the upper platform 110 to enable the lower platform 120 to be connected to any desired step member 174.

[0169] The components of the adjustable desk assembly 100 in FIGS. 5A-5B can be formed of any suitable materials including one or more metals, one or more wood materials, one or more polymers, one or more plastics, etc. In some examples, the housing 511 and shaft member 512 may be formed from one or more metals, the post member 130 and platform connection column 170 may be formed of one or more wood materials, and the platforms may be formed of one or more polymers, one or more plastics, and / or one or more wood materials.

[0170] The structure or configuration of the adjustable desk assembly 100 in FIGS. 5A-5B can be varied in numerous ways. In one example, one or more of the platforms may be stationary platforms integrally connected to the platform connection column 170, while in other cases all of the platforms can be configured to be adjustable and / or repositioned to desired steps. Additionally, the adjustable desk assembly 100 can be configured with a lesser number of platforms (e.g., a single platform) and / or a greater number of platforms (e.g., three or more platforms), each of which can be either stationary or movable. In another example, the configurations of the connector 513 and post connection interfaces 514 can be varied to incorporate other types of connection schemes (e.g., such as those that utilize pin-and-hold connection schemes, dovetail joint arrangements, rack-and-pinion mechanisms, magnetic couplings, clamping mechanisms, bayonet mounting configurations, quick release mechanisms, interlocking rail connectors, and / or many other types of connection schemes). The housing 511 may be configured in various shapes and sizes, such as a rectangular prism, cylindrical column, or tapered structure, and may be constructed from different materials including metals, woods, plastics, polymers, and / or composite materials.

[0171] Additionally, the adjustable desk assembly 100 in FIGS. 5A-5B can be incorporated or adapted for various types of installation arrangements. In some cases, the adjustable desk assembly 100 can be arranged in a mounted configuration and may include one or more mounting interfaces 160 for coupling the adjustable desk assembly 100 to a wall or other mounting surface. Additionally, or alternatively, the adjustable desk assembly 100 can be incorporated into stationary desk configurations and / or mobile desk configurations (e.g., such that a bottom portion of the housing is connected to the stationary or mobile structures).

[0172] ​FIGS. 6A-6E disclose additional embodiments of an adjustable desk assembly 100. These embodiments include additional adjustable desk assemblies 100 that are arranged in an ultra-compact configuration, which can be particularly beneficial when installed in environments having limited available space.

[0173] Like the embodiment illustrated in FIGS. 5A-5B, the adjustable desk assembly 100 in FIG. 6A comprises a post adjustment assembly 510 that enables the height or position of the post member 130 to be adjusted. However, the post adjustment assembly 510 in FIG. 6A incorporates a different connection scheme that utilizes different types of post connection interfaces 514 and the post member 130 includes a different type of connector 513.

[0174] Specifically, in the example of FIG. 6A, an interlocking connection configuration 610 is shown, in which the connector 513 comprises one or more hook members 161 included on a rear surface 132 of the post member 130, and the post connection interfaces 514 include one or more slot members 162 included on the front surface of the post adjustment assembly 510. In this example, the rear surface 132 of the post member 130 includes a single hook member 161, which is configured in a downwardly facing L-shape and adapted to connect to each of the slot members 162. A first portion of the hook member 161 extends outward from rear surface 132 and a second portion extends downward from the first portion. The post adjustment assembly 510 also includes a plurality of slot members 162, each of which is configured in an upwardly facing L-shape. Each of the slot members 162 includes a first portion that extends outward from the front surface of the post adjustment assembly 510 and a second portion that extends upward from the first portion. For each slot member 162, a recess is formed in the area between the front surface of the post adjustment assembly 510 and the second portion of the slot member. The second portion of the hook member 161 may be adapted to mate with each of the recesses to secure the post member 130 to the post adjustment assembly 510.

[0175] In operation, an individual can manually reposition the post member 130 along the height or length of the post adjustment assembly 510 by disengaging an interlocking connection formed between a hook member 161 and a slot member 162, and moving the platform to a position of a separate slot member 162 and inserting the hook member 161 into the slot member 162, thereby connecting the post member 130 at a different height or location along the post adjustment assembly 510.

[0176] In this configuration, the post member 130 is integrated with a pair of platform connection columns 170, which are spaced apart from each other and situated or aligned parallel to each other. Each of the platform connection columns 170 extends outward from a front surface of the post member 130 (e.g., at or near the left and right edges of the front surfaces).

[0177] Each of the platform connection columns 170 comprises a plurality of repeating step members 174, each of which includes a shelf portion 176 and a wall 177 that extends downwardly from the shelf portion 176 and inwardly towards the direction of the post member 130. Like the embodiment in FIGS. 5A-5B, the step members 174 are arranged in a cascading configuration 179A, whereby each successive step extends further outward from the post member 130. The topmost step member 174 is positioned closest to the post member 130, while each subsequent step protrudes incrementally further outward, with the bottommost step member 174 extending the farthest from the post member 130.

[0178] Recesses 178 are formed between each of the shelf portions 176 and / or each of the step members 174. The platforms (such as the upper platform 110 and / or lower platform 120) can be manually positioned into the recesses 178 to arrange the platforms at desired heights. Additionally, in this exemplary embodiment, each platform is configured with a connecting surface 113A that couples the platform to the various step members 174 included on the pair of platform connection columns 170. For example, the connecting surface 113A may comprise openings or conduits that extend through the platforms, and which are adapted to receive upper portions of two adjacent step members 174 (e.g., sized and adapted to receive two adjacent shelf portions 176). In some cases, one or more connection assemblies 140 also can be utilized to lock or secure the platforms at desired locations.

[0179] FIGS. 6B-6C disclose another embodiment of an adjustable desk assembly 100 arranged in a compact configuration.

[0180] Similar to some other embodiments described above, the adjustable desk assembly 100 comprises a pair of platform connection columns 170 extending outwardly from the front surface of the post member 130. That is, a first platform connection column 170 is situated on the left side of the front surface of the post member 130 and a second connection column 170 is situated on the right side of the front surface of the post member 130. The first and second platform connection columns are arranged parallel, or substantially parallel, to each other and are spaced apart a distance (e.g., in some cases, approximately 3-12 inches or 6 inches) on the front surface of the post member 130. When viewed from above or below, a U-channel is formed by the post member 130, the first platform connection column 170, and the second platform connection column 170.

[0181] Again, each of the platform connection columns 170 comprises a plurality of repeating step members 174, each of which includes a shelf portion 176 and a wall 177 that extends downwardly from the shelf portion 176 and inwardly towards the direction of the post member 130. Recesses 178 are formed between each of the shelf portions 176 and / or each of the step members 174. The step members 174 are arranged in a cascading configuration 179A, with each successive step extending further outward from the post member 130. The topmost step member 174 is positioned closest to the post member 130, while each subsequent step protrudes incrementally further outward, with the bottommost step member 174 extending the farthest from the post member 130.

[0182] Similar to the embodiments in FIGS. 5A-5B and 6A, the upper platform 110 and / or lower platform 120 can be manually positioned into the recesses 178 to arrange the platforms at desired heights, and each platform can be outfitted with a connecting surface 113A that is capable of coupling the platform to the various step members 174 included on the pair of platform connection columns 170. For example, the connecting surface 113A may comprise openings or conduits that extend through the platforms, and which are adapted to receive upper portions of two adjacent step members 174 (e.g., sized and adapted to receive two adjacent shelf portions 176). In some cases, one or more connection assemblies 140 also can be utilized to lock or secure the platforms at desired locations.

[0183] To help secure each platform to a desired step member 174 (or at a desired height along the platform connection columns 170), a bottom surface of the platform may include an insert member 148 that extends downwardly from the bottom surface. In some embodiments, the insert member 148 may be designed or shaped to fit into the recesses 178 between the step members 174. For example, the insert member 148 may configured in a triangular shape and / or may include angled walls that are adapted to be received in the recesses 178. The receiving of the insert member 148 in a recess can assist both with securing the platform to the platform connection columns 170 and providing stability or support to the platform when it is being utilized.

[0184] In operation, an individual can manually reposition each platform (including the upper platform 110 and lower platform 120) along the height of the platform connection columns 170 by disengaging the connecting surface 113A (e.g. by lifting the platform upward to dislodge the shelf portions 176 from opening in the connecting surface 113A), and moving the platform to a position of a desired step member 174. The platform can be connected to the desired step member 174 by inserting the shelf portions 176 (or upper portions of the step member 174) into or through the connecting surface 113A. Additionally, when the connecting surface 113A is aligned with the shelf portions 176, the insert member 148 extending from the bottom surface of the platform can be received in a recess 178 situated beneath the desired step member 174, thereby securing the platform at the desired height and providing additional stability and support for the platform.

[0185] In certain embodiments, the adjustable desk assembly 100 in FIGS. 6B-6C may include one or more mounting interfaces 160 that enable the adjustable desk assembly 100 to be connected to a wall or other mounting surface. For example, in some cases, openings or holes may be provided on the post member 130 to enable the rear surface of the post member 130 to be connected to the mounting surface (e.g., using screws, nails, or other hardware).

[0186] Alternatively, the post member 130 or other portion of the adjustable desk assembly 100 in FIGS. 6B-6C may include one or more connectors 513 that permit the assembly to be attached to a post adjustment assembly 510. Any connection scheme (including, but not limited to, any of those mentioned in this disclosure) can be utilized to couple the post member 130 or the adjustable desk assembly 100 to the post adjustment assembly 510. In some examples, the one or more connectors 513 may include openings or female portions that are configured to engage extensions, protrusions, or male portions extending outward from a surface of the post adjustment assembly 510.

[0187] As explained above, embodiments that incorporate a post adjustment assembly 510 can enable the post member 130 and / or adjustable desk assembly 100 to be repositioned at different heights along the post adjustment assembly 510. In some embodiments, the adjustable desk assembly 100 can be outfitted with one or more handles 164 that enable a user to grip or lift the adjustable desk assembly 100 for repositioning along the post adjustment assembly 510. In the example illustrated in FIGS. 6B-6C, a pair of handles 164 (e.g., which may include openings for receiving the hands or fingers of the user) are incorporated into lower portions of the platform connection columns 170.

[0188] FIGS. 6D-6E disclose another exemplary variation of an adjustable desk assembly 100 according to certain embodiments.

[0189] Similar to several embodiments described above, the adjustable desk assembly 100 comprises a pair of platform connection columns 170 extending outwardly from the front surface of the post member 130, such that a first platform connection column 170 is situated on the left side of the front surface of the post member 130 and a second connection column 170 is situated on a right side of the front surface of the post member 130. When viewed from above or below, a U-channel is formed by the post member 130, the first platform connection column 170, and the second platform connection column 170.

[0190] Again, each of the platform connection columns 170 comprises a plurality of repeating step members 174, and each includes a shelf portion 176 and a wall 177 that extends downwardly from the shelf portion 176 and inwardly towards the direction of the post member 130 with recesses 178 being formed between each of the shelf portions 176 and / or each of the step members 174. Unlike some of the exemplary configurations described above which include a sloping or cascading arrangement of the step members 174, the step members 174 are arranged in a straight or linear configuration 179B in which each successive step is aligned directly beneath or above an adjacent step member 174. In this configuration 179B, each step member 174 extends the same distance from the post member 130. This straight or linear arrangement can be beneficial because it further reduces the size or footprint of the adjustable desk assembly 100 in the horizontal direction.

[0191] In operation, an individual can manually reposition each platform (including the upper platform 110 and lower platform 120) along the height of the platform connection columns 170 in the same or similar manner described above (e.g., by disengaging the connecting surface 113A and moving the platform to a position of a desired step member 174).

[0192] The components of the adjustable desk assemblies 100 in FIGS. 6A-6E can be formed of any suitable materials including one or more metals, one or more wood materials, one or more polymers, one or more plastics, etc. In some examples, the post adjustment assembly 510, post member 130, and platform connection columns 170 may be formed from one or more wood materials, and the platforms may be formed of one or more polymers, one or more plastics, and / or one or more wood materials.

[0193] The structure or configuration of the adjustable desk assemblies 100 in FIGS. 6A-6E can be varied in numerous ways. In one example, one or more of the platforms may be stationary platforms integrally connected to the platform connection column 170, while in other cases all of the platforms can be configured to be adjustable and / or repositioned to desired steps. Additionally, adjustable desk assembly 100 can be configured with a lesser number of platforms (e.g., a single platform) and / or a greater number of platforms (e.g., three or more platforms), each of which can be either stationary or movable. In another example, the configurations of the interlocking connection configuration 610 shown in FIG. 6A can be modified and / or can be replaced to incorporate other types of connection schemes (e.g., including any of the connection schemes mentioned in this disclosure). The post adjustment assemblies 510 may be configured in various shapes and sizes, such as a rectangular shape, a cylindrical shape, or a tapered structure, and may be constructed from different materials,

[0194] Additionally, the adjustable desk assembly 100 in FIGS. 6A-6E can be incorporated or adapted for various types of installation arrangements. In some cases, the adjustable desk assembly 100 can be arranged in a mounted configuration and may include one or more mounting interface 160 for coupling the adjustable desk assembly 100 to a wall or other mounting surface. Additionally, or alternatively, the adjustable desk assembly 100 can be incorporated into stationary desk configurations and / or mobile desk configurations (e.g., such that a bottom portion of the post adjustment assembly 510 is connected to such stationary or mobile structures).

[0195] FIGS. 7A and 7B disclose embodiments in which an adjustable desk assembly 100 is integrated into stationary desk assemblies 750.

[0196] In FIG. 7A, a stationary desk assembly 750 includes a desk frame 730 that rests on an underlying surface. In this example, the desk frame 730 comprises a rectangular structure that includes a plurality of storage compartments 720. An upper portion of the desk frame 730 comprises a stationary surface 710, that can be utilized for working or other purposes.

[0197] In certain embodiments, the adjustable desk assembly 100 can be connected to and / or extend upwardly above the stationary surface 710 of the stationary desk assembly 750. Additionally, or alternatively, the adjustable desk assembly 100 can be coupled to a back surface of the frame 730 and / or other surface incorporated into the stationary desk assembly 750.

[0198] In certain embodiments, a mounting interface 160 situated on the post member 130 can be utilized to couple the adjustable desk assembly 100 to the stationary desk assembly 750. In some examples, the mounting interface 160 may be located on the lower portion of the post member 130, and the mounting interface 160 can couple the post member 130 to the stationary surface 710 and / or rear surface of the stationary desk assembly 750.

[0199] In some embodiments, the stationary desk assembly 750 also may include a back wall 760, e.g., which can include a structure that is coupled to the rear surface of the stationary desk assembly and which extends a height (e.g., several feet) above the stationary surface 710. In such embodiments, one or more mounting interfaces 160 can be incorporated into various portions of the post member 130 (e.g., top, bottom, or middle portions) to enable the post member 130 to be coupled to the back wall of the stationary desk assembly 750.

[0200] The stationary desk assembly 750 can be adapted to include any number of storage compartments 720. In some embodiments, the stationary desk assembly 750 may incorporate a single storage compartment 720, while in other cases, it may feature multiple storage compartments 720 arranged in various configurations. The number and arrangement of storage compartments 720 may be customized based on user preferences, available space, and intended functionality. These storage compartments 720 may include drawers of various sizes and depths, open or closed shelves, cubbies or cubby holes, file cabinets, sliding trays, pull-out bins, overhead compartments, vertical storage slots, cable management compartments, lockable cabinets, and / or other similar structures.

[0201] In FIG. 7B, a stationary desk assembly 750 includes a structure that is supported by a plurality of leg members 740 (e.g., four leg members 740), which rest on an underlying surface. In this example, the stationary desk assembly 750 does not include a stationary surface 710. Instead, the lower platform 120 has an expanded size and serves the same function as the stationary surface 710. In this configuration, the lower platform 120 may have openings that enable the leg members 740 to extend through the lower platform 120, and which enable the lower platform 120 to be moved upward and downward along both the post member 130 and the leg members 740. In certain embodiments, one or more mounting interfaces 160 included on the post member 130 may couple the adjustable desk assembly 100 to a support member 770 that extends between, and which is coupled to, the leg members 740.

[0202] The configurations of leg-based stationary desk assemblies 750 can vary greatly, and the adjustable desk assembly 100 can be coupled to other surfaces of the stationary desk assemblies 750 based on the configurations. In some examples, a stationary desk assembly 750 having leg members may include one or more stationary surfaces 710 and / or one or more back walls 760, and the adjustable desk assembly 100 or post member 130 can be coupled to the one or more stationary surfaces 710 and / or the one or more back walls 760.

[0203] The arrangements illustrated in FIGS. 7A-7B represent exemplary configurations for integrating an adjustable desk assembly 100 with stationary desk assemblies 750. However, these examples are not intended to be limiting, and the adjustable desk assembly 100 may be incorporated into various other types of stationary desk assemblies 750. Additionally, the integration of the adjustable desk assembly 100 can be accomplished in either a fixed arrangement (e.g., such that the adjustable desk assembly 100 is permanently coupled to the stationary desk assemblies 750 and / or cannot be easily removed) or removable arrangement (e.g., such that the adjustable desk assembly 100 is adapted to be removable and / or re-connectable to the stationary desk assemblies 750). The methods for connecting the adjustable desk assembly 100 to stationary desk assemblies 750 also may vary. For instance, the adjustable desk assembly 100 may be attached to different surfaces or components of the stationary desk assemblies 750, such as top surfaces, side panels, back panels, or internal structural elements.

[0204] FIG. 8 discloses an exemplary mobile desk assembly 800 that includes an adjustable desk assembly 100. In certain embodiments, the mobile desk assembly 800 can include, inter alia, one or more movement-enabling structures 810 and a base portion 820 connected to the one or more movement-enabling assemblies 810. The mobile desk assembly 800 may optionally include one or more frames 830 and / or one or more storage compartments 720.

[0205] ​The movement-enabling structures 810 can permit the mobile desk assembly 800 to be easily moved, positioned, or transported to desired locations. In one exemplary use case, the movement-enabling structures 810 can enable a user to move the mobile desk assembly 800 from the user's office to a conference room. In another exemplary use case, the movement-enabling structures 810 may allow a user to reposition the mobile desk assembly 800 within a home office to take advantage of natural lighting throughout the day. In another exemplary use case, the movement-enabling structures 810 may enable educational or business institutions to easily reconfigure classroom or working layouts by moving multiple mobile desk assemblies 800 to create different seating arrangements or collaborative workspaces. In another exemplary use case, the movement-enabling structures 810 also may facilitate the relocation of mobile desk assemblies 800 in shared co-working spaces, allowing users to create temporary personal workstations in different areas of the facility.

[0206] In some embodiments, the movement-enabling structures 810 can include wheels. Additionally, or alternatively, the movement-enabling structures 810 may include sliders, rollers, casters, glides, leveling feet, ball transfer units, air casters, omnidirectional wheels, swivel plates, skid plates, or any combination thereof.

[0207] In this exemplary configuration, the movement-enabling structures 810 are connected to a bottom surface of the base portion 820, and the top surface of the base structure includes a connecting structure 840 that couples the adjustable desk assembly 100. In some embodiments, the adjustable desk assembly 100 may additionally, or alternatively, be coupled to a frame 830 of the mobile desk assembly 800.

[0208] ​The stationary desk assemblies 750 and mobile desk assemblies 850 described in this disclosure (including, but not limited to, those illustrated in FIGS. 7A, 7B and 8) can be adapted to include any of the adjustable desk assemblies 100 described in this disclosure including, but not limited to, those illustrated in FIGS. 1A-D and 3, 5A-5B and 6A-6E.

[0209] ​FIGS. 9A and 9B illustrate how an exemplary adjustable desk assembly 100 can be arranged in both a seating configuration 900A and standing configuration 900B. In both the seating configuration 900A and the standing configuration 900B, the upper platform 110 and lower platform 120 can be arranged to optimize ergonomic benefits and specifically position the platforms at locations that are optimized specifically for the particular user 905 (e.g., to adjust the platforms at locations that accommodate the stature, height, arm length, and / or size of the user 905).

[0210] In FIG. 9A, the user 905 is seated in a chair assembly 920 and both the upper platform 110 and lower platform 120 are adjusted to positions that eliminate, or at least significantly mitigate, strains on the user 905.

[0211] Specifically, the lower platform 120 is situated at an ideal height to accommodate the arm position of the user in the chair assembly 920. In this example, the user 905 can comfortably operate a mouse device and / or keyboard device situated on the lower platform 120. The height of lower platform 120 is substantially aligned with the height of the armrests 925 included on the chair assembly 920 and / or aligned with the height of the user’s elbows, thereby allowing the user's forearms to remain in a substantially straight or lateral arrangement when operating the mouse device and / or keyboard device and reducing the strain on the user's hands and wrists. In some exemplary ergonomic arrangements, an angle of approximately 90-100 degrees is formed between the top of the user's arm and the user's chest or body to facilitate this ergonomic arrangement.

[0212] Additionally, in FIG. 9A, a monitor device is situated on the upper platform 110, and the upper platform 110 is situated at an ideal height to accommodate the head or neck position of the user 905 while seated in the chair assembly 920. In some exemplary ergonomic arrangements, the monitor device may be positioned approximately 50-60 centimeters (cm) from the user 905 and an angle of approximately 40-45 degrees is formed between the user's eyeline, and the top and bottom portions of the monitor device, thereby allowing the user's head and neck to remain in a substantially straight or upright arrangement when viewing the monitor device and reducing the strain on the user's neck.

[0213] In FIG. 9B, the user 905 is in a standing position and both the upper platform 110 and lower platform 120 are repositioned along the post member 130 to optimal heights, again reducing the strains on both the user's wrists and neck regions. The height of lower platform 120 is substantially aligned with the height of the user's forearms or elbows in the standing position, thereby allowing the user's arms to remain in a substantially straight or lateral arrangement when operating the mouse device and / or keyboard device and reducing the strain on the user's hands and wrists. Again, in some exemplary ergonomic arrangements, an angle of approximately 90-100 degrees may be formed between the top of the user's arm and the user's chest or body.

[0214] Additionally, in FIG. 9B, a monitor device is situated on the upper platform 110, and the upper platform 110 is situated at an ideal height to accommodate the head or neck position of the user 905 while in the standing position. In some exemplary ergonomic arrangements, the monitor device may be positioned approximately 50-60 cm from the user 905 and an angle of approximately 40-45 degrees is formed between the user's eyes, and the top and bottom portions of the monitor device, thereby allowing the user's head and neck to be remain in a substantially straight or upright arrangement when viewing the monitor device and reducing the strain on the user's neck.

[0215] ​FIGS. 9A and 9B illustrate how the adjustable desk assembly 100 permits the platforms to be rearranged or repositioned to simultaneously reduce strains on different parts of the user's body. The independent adjustability of the upper platform 110 and lower platform 120 allows for customized configurations that can accommodate users of varying sizes, heights, and proportions, and also accommodate usage of the adjustable desk assembly 100 in both standing and seating arrangements. By enabling precise positioning of both the monitor and input devices, the adjustable desk assembly 100 may help minimize strain on the user's neck, eyes, shoulders, arms, wrists, and hands concurrently. This versatility allows the adjustable desk assembly 100 to be tailored to the specific ergonomic needs of different individuals, potentially improving comfort and reducing the risk of repetitive strain injuries across a diverse range of users.

[0216] FIGS. 9A and 9B illustrate the adjustable desk assembly 100 in a mounted configuration in which the adjustable desk assembly 100 is connected to a mounting surface 910 (e.g., a wall). As explained above, the adjustable desk assembly 100 can be incorporated into other arrangements (e.g., stationary or mobile desk arrangements), and the same ergonomic and strain-reducing benefits mentioned above equally apply to those alternative arrangements.

[0217] FIGS. 11A-11F, 12, and 13A-13C, illustrate another exemplary adjustable desk assembly 100 in accordance with certain embodiments. FIGS. 11A-11F illustrate how the adjustable desk assembly 100 can be transitioned between a compacted, spacing-saving configuration 105 and various operational configurations, including a first operational configuration 107A that enables the adjustable desk assembly 100 to be utilized in a standing position, a second operational configuration 107B that enables the adjustable desk assembly 100 to be utilized in a chair-seated position, and a third operational configuration 107C that enables the adjustable desk assembly 100 to be utilized in a floor-seated position. FIG. 12 illustrates an exploded view of the adjustable desk assembly 100, highlighting exemplary components that can be arranged to assemble the adjustable desk assembly 100. FIGS. 13A-13C illustrate the adjustable desk assembly 100 being utilized by an individual in the first operational configuration 107A, second operational configuration 107B, and third operational configuration 107C.

[0218] The adjustable desk assembly 100 comprises two cooperating structures: an enclosure 1110 and a height-adjustable platform carriage 1120. The enclosure 1110 includes a rear wall 1111 and a pair of enclosure side walls 1112 coupled to the rear wall 1111 in a substantially perpendicular manner such that, when viewed from the top or bottom, the enclosure defines a U-shaped channel that opens toward the user. Guidance structures 1113 are coupled to inward-facing surfaces of the enclosure side walls 1112. In some examples, the guidance structures 1113 comprise linear translation assemblies having stationary rails or tracks fixed to the side walls 1112 that slidably interface with complementary moving elements on the carriage 1120. The enclosure 1110 may further include a mounting interface 160 adapted to couple the rear wall 1111 to a wall and / or other surface.

[0219] The height-adjustable platform carriage 1120 is received within the enclosure 1110 and is movably coupled thereto by the guidance structures 1113. The carriage 1120 includes a pair of carriage support members 1125, which include outer surfaces engaged with the guidance structures 1113 and inner surfaces that support and carry an upper platform 110 and a lower platform 120. In some embodiments, a tray structure 1127 is integrated near the bottom of the carriage 1120 and provides a guided interface, such as rails and cooperating rolling or sliding elements on the lower platform 120, that allows the lower platform 120 to translate between inserted and extended positions and to rotate upward when extended. A post member 130 on or adjacent to the rear wall 1111 includes a height-adjustable extension member 1151 that forms part of a motorized adjustment assembly 150A. The height-adjustable extension member 1151 can include a telescoping arm or leg that is coupled to the carriage 1120 such that extension and retraction of the member 1151 translate the carriage 1120 vertically within the enclosure 1110.

[0220] In operation, the motorized adjustment assembly 150A drives the height-adjustable extension member 1151 to raise and lower the carriage 1120 along the guidance structures 1113 while maintaining a stable, guided motion. Unlike configurations in which an under-desk actuator lifts a work surface upward, the extension member 1151 in this embodiment is positioned above the platforms and is configured to extend downward to lower the carriage 1120 and retract upward to raise the carriage 1120. This geometry enables the platforms to be positioned at very low elevations for floor-seated use and at higher elevations for chair-seated or standing use, as shown in FIGS. 13A-13C. During vertical movements, a fixed spacing between the upper platform 110 and the lower platform 120 preserves ergonomic relationships between monitor and input devices, while optional carriage-level mechanisms can provide additional fine adjustment if desired.

[0221] The adjustable desk assembly 100 can be transitioned between operational configurations and a compacted, space-saving configuration 105 without the need to retool or remove components from the assembly. To compact the assembly, the motorized adjustment assembly 150A can be controlled to initially position the carriage 1120 such that the lower platform 120 is substantially aligned with the lower edges of the enclosure side walls 1112 (FIG. 11D). The user then pulls the lower platform 120 outward along the tray structure 1127 (FIG. 11C) and rotates it upward approximately ninety degrees to a stowed orientation adjacent to the open front of the enclosure 1110, where a securing mechanism retains the platform in place, forming a generally box-like profile as shown in FIG. 11A.

[0222] In the compacted configuration 105 (FIG. 11A), the lower platform 120 is fully stowed within the footprint of the enclosure 1110 and does not protrude into the room, thereby eliminating obstructions and reducing the likelihood of accidental contact when the assembly is not in use. By presenting a generally box-like profile, the assembly occupies minimal depth and frees usable floor area for circulation or other activities. This space-saving mode can be particularly advantageous in urban living scenarios, smaller apartments, multi-purpose rooms, and other space-limited environments, where temporary clearance may be needed for other activities when the adjustable desk assembly 100 is not in use. The ability to transition quickly into and out of the compacted state without tools or disassembly improves stowage capabilities, maintains a tidy aesthetic, and helps accommodate flexible, high-density living arrangements.

[0223] To deploy the adjustable desk assembly 100 for usage, the securing mechanism can be released, permitting the lower platform 120 to be rotated downward approximately ninety degrees to a generally horizontal orientation (FIGS. 11B-C). When the lower platform 120 is position in the horizontal arrangement, it can then be pushed or slid inward along the tray structure 1127 (FIG. 11D). Thereafter, the motorized adjustment assembly 150A can be activated to position the carriage 1120 at a desired height.

[0224] In certain embodiments, activation of the motorized adjustment assembly 150A positions the carriage 1120 at heights corresponding to distinct operational configurations. As shown in FIG. 13A, the carriage 1120 can be raised so that the adjustable desk assembly 100 is arranged in a first operational configuration 107A suitable for standing use. In this state, the height-adjustable extension member 1151 is retracted upward, translating the carriage 1120 along the guidance structures 1113 to elevate the upper platform 110 and lower platform 120. The lower platform 120 may thereby be aligned approximately with the user’s forearms or elbows in the standing position to promote neutral wrist orientation during input tasks, while the upper platform 110 can be positioned so that a supported monitor or display is at an appropriate eye level and viewing distance.

[0225] As shown in FIG. 13B, the same motorized adjustment assembly 150A can be actuated to arrange the carriage 1120 in a second operational configuration 107B for chair-seated use. In this state, the height-adjustable extension member 1151 is partially extended downward to locate the carriage 1120 at an intermediate elevation. The lower platform 120 can be positioned so that the user’s hands rest comfortably with the elbows at an ergonomically favorable angle while seated, and the upper platform 110 can be set to align the user’s eyeline with the upper portion of a supported monitor to mitigate neck flexion.

[0226] As shown in FIG. 13C, the extension member 1151 may be extended further downward to lower the carriage 1120 into a third operational configuration 107C for floor-seated use. Because the actuator is mounted above the platforms and extends downward to lower the carriage 1120, very low working elevations can be achieved while maintaining guided, stable motion within the enclosure 1110. In this state, the lower platform 120 can be positioned proximate to the user’s lap level for comfortable input while seated on the floor, and the upper platform 110 can be set for a suitable line of sight to a supported display.

[0227] While FIGS. 13A-13C illustrate three exemplary positions, the carriage 1120 is not limited to these three discrete positions. The motorized adjustment assembly 150A can position the carriage 1120 at any point along the available vertical axis defined by the guidance structures 1113, thereby enabling fine-grained placement tailored to user characteristics such as standing height, seated height, arm length, and / or preferred viewing distance. This continuous adjustability permits the lower platform 120 to be aligned with the user’s hands or forearms for input tasks and the upper platform 110 to be aligned with the user’s field of view for display use, allowing the ergonomic relationship between input and display surfaces to be precisely maintained across standing, chair-seated, and floor-seated postures.

[0228] The exploded view in FIG. 12 illustrates exemplary components that can be incorporated to assemble the adjustable desk assembly 100. The adjustable desk assembly 100 incorporates four primary components: the enclosure 1110, the mounting interface 160, the height-adjustable platform carriage 1120, and the post member 130, which includes the motorized adjustment assembly 150A and height-adjustable extension member 1151. Each of these is described in further detail below.

[0229] In certain embodiments, the enclosure 1110 includes a rear wall 1111 and a pair of enclosure side walls 1112 coupled to the rear wall 1111 in a substantially perpendicular manner. The enclosure side walls 1112 are arranged substantially parallel to one another, and together with the rear wall 1111 define a U-shaped channel that opens toward the user when viewed from the top or bottom. A spacing is thus formed between the side walls 1112 within the U-channel, and this spacing is sized to receive the height-adjustable platform carriage 1120 so that the carriage can translate vertically within the enclosure 1110 under guidance of the structures 1113.

[0230] Guidance structures 1113 are disposed along inward-facing surfaces of the enclosure side walls 1112 and are positioned to cooperate with complementary elements on a height-adjustable platform carriage 1120 to guide vertical translation of the carriage within the enclosure 1110. Each enclosure side wall 1112 may include a pattern of openings dimensioned to receive fasteners or other connectors for attaching the guidance structures 1113. In some examples, the openings are elongated slots. In some examples, the guidance structures 1113 can be fastened to the side walls 1112 by screws, bolts, rivets, threaded inserts, or other suitable hardware, and may include standoffs or spacers to establish a desired clearance between the structures and the side walls.

[0231] While the guidance structures 1113 are illustrated as rails or tracks, other mechanisms capable of providing low-friction, guided vertical motion can be employed. In some examples, the guidance structures 1113 may comprise linear ball-bearing slides, crossed-roller slides, recirculating linear guides, bushings on polished guide rods, cam-follower track systems, rack-and-pinion linear guides, belt-or-cable driven carriages with captive pulleys, dovetail ways, low-friction glide pads with wear strips, or combinations thereof. Any arrangement that constrains the carriage 1120 to a controlled vertical path while supporting operational loads may be utilized.

[0232] The rear wall 1111 may include one or more arrays of openings configured to receive connectors for coupling the enclosure 1110 to a mounting interface 160. In some implementations, the openings are compatible with wall-mounted bracket assemblies and are positioned to distribute loads into the rear wall 1111, permitting the enclosure 1110 to be secured to the wall or supporting structure. In some examples, the connectors can include screws, bolts, anchors, threaded inserts, keyhole features, or other hardware, and may be arranged to permit level adjustment and repeatable installation.

[0233] In the exemplary configuration illustrated in FIG. 12, the mounting interface 160 comprises a bracket assembly that includes a pair of vertical members adapted to be fastened to a wall or other supporting surface and a pair of horizontal members adapted to couple to an outer surface of the rear wall 1111. The horizontal members may connect directly to the rear wall 1111 and may also mechanically interface with the vertical members to create a rigid perimeter frame that distributes loads into the building structure. In some implementations, the vertical members include elongated slots for height and level adjustment during installation, and the horizontal members include mating features, such as keyed apertures or tab-and-slot connections, that engage corresponding features on the vertical members to provide repeatable alignment. Fasteners, such as screws or bolts, may be used to secure the horizontal members both to the rear wall 1111 and to the vertical members once positional adjustments are complete.

[0234] Other suitable mounting mechanisms may also be employed. In some examples, the enclosure 1110 may be secured using French cleats, keyhole plates, interlocking rail systems, or T-slot extrusions. In further examples, clamp-on brackets for partition panels, adhesive-backed plates with mechanical safeties, threaded inserts anchored into studs, or quick-release latch plates may be used. Any mounting arrangement that provides sufficient load-bearing capacity and positional stability, and that permits accurate alignment of the enclosure 1110 on a supporting structure, can be utilized.

[0235] In certain embodiments, the height-adjustable platform carriage 1120 includes a pair of carriage support members 1125, an upper platform 110, a lower platform 120, and a tray structure 1127. The carriage support members 1125 are arranged substantially parallel to one another and extend generally upward in a direction perpendicular to the planes of the platforms. The upper platform 110 is coupled to the support members 1125 at an elevation above the lower platform 120, and the lower platform 120 is received and supported by the tray structure 1127 situated near the bottom of the carriage 1120.

[0236] In the illustrated configuration, the upper platform 110 presents a smaller surface area than the lower platform 120, and the lower platform 120 extends farther outward from the direction of the rear wall 1111 to provide additional room for input devices and accessories, while the upper platform 110 is sized to support a display device at an ergonomic viewing distance. As explained in other portions of this disclosure, the size, shape, and configuration of the two platforms can be varied.

[0237] The outer surfaces of the support members 1125 interface with the guidance structures 1113 mounted on the enclosure side walls 1112 so that the carriage 1120 translates vertically as a unit within the enclosure 1110. In operation, actuation of the motorized adjustment assembly 150A causes the support members 1125 to move upwardly and downwardly along the guidance structures 1113 while maintaining lateral constraint. When the carriage 1120 is positioned at higher elevations, the majority of the support members 1125 are concealed behind the enclosure side walls 1112. When the carriage 1120 is positioned at lower elevations, the lower portions of the support members 1125 are exposed and extend below the bottom edges of the enclosure side walls 1112, as shown in the figures, to accommodate very low working heights.

[0238] The upper platform 110 can include a rear cutout or recess aligned with the post member 130 to permit passage of the height-adjustable extension member 1151. This cutout allows the telescoping member 1151 to extend through the plane of the upper platform 110 without interference as it couples to and actuates the carriage 1120. The cutout maintains a compact fore-aft depth for the upper platform 110 while preserving clearance for the actuator throughout its stroke.

[0239] The tray structure 1127 provides a guided and supportive interface for the lower platform 120. In the illustrated embodiment, the tray structure 1127 includes a generally horizontal base surface that faces upward and two end walls that extend upward from opposite ends of the base surface, thereby defining a U-channel that opens upward when viewed from a front perspective. The U-channel receives edge regions or engagement features of the lower platform 120 so that, when the lower platform 120 is pushed inward, the platform rests on and is supported by the base surface of the tray 1127 with the end walls providing lateral constraint.

[0240] A connection mechanism between the tray structure 1127 and the lower platform 120 enables both supporting and stowing functions. In some embodiments, the connection mechanism includes elongate rails integrated into the tray structure 1127 and complementary rolling or sliding elements on the underside of the lower platform 120 that permit the platform to translate between an inserted position and an extended position. At or near the outward end of travel, the connection mechanism presents a controlled pivot interface that allows the lower platform 120 to rotate upward approximately ninety degrees into a stowed orientation. When the lower platform 120 is translated inward, the platform is supported by the horizontal surface of the tray structure 1127 during normal use, while translation outward and rotation upward permit compact storage as described in other portions of this disclosure.

[0241] The post member 130 in this embodiment comprises a height-adjustable extension member 1151 that is positioned above the platforms and coupled to the front surface of the rear wall 1111. In this example, the extension member 1151 includes a telescoping lifting column integrated with a motorized actuator 1152, such as an electric linear actuator, electric motor, and / or other type of actuator or motor. In the illustrated configuration, the extension member 1151 is formed as a multi-segmented telescopic arm (e.g., a three-segment column) arranged in an L-shape in which a primary vertical telescoping column connects to the rear wall 1111 of the enclosure 1110. The extension member 1151 extends downward and terminates at a forward-extending foot member. In some embodiments, the foot member houses the motorized actuator 1152, and a gear system is integrated within the column so that rotation from the motor is translated into linear extension and retraction of the segments. When the adjustable desk assembly 100 is assembled, the primary vertical telescoping column of the extension member 1151 extends through a cutout in the upper platform 110 and the foot member extends outward beneath the upper platform 110.

[0242] In some embodiments, the electric lifting column can be operated by a control switch or a programmable controller and, in some cases, permits users to set or recall preferred heights. In some examples, a user-interface button is integrated on the extension member 1151 itself and / or located on another portion of the adjustable desk assembly 100. In further examples, the actuator can additionally be commanded via a paired device such as a smartphone, tablet, or desktop computer. The telescoping architecture allows the column to compact when stowed and to extend to various heights during use, delivering smooth, guided vertical motion of the carriage 1120 within the enclosure 1110 with the convenience of push-button adjustment.

[0243] In alternative configurations, the post member 130 (including the height-adjustable extension member 1151 and a foot member) may be situated beneath the carriage 1120, with the foot member oriented upward. In such an arrangement, the actuator operates to push the carriage 1120 upward, and the telescoping column expands as the carriage rises. While functional, this under-carriage push configuration constrains how far the carriage 1120 can be extended downward because the column, actuator package, and foot member occupy space below the platforms, thereby limiting downward travel and effectively precluding very low working elevations suitable for floor-seated use.

[0244] By contrast, the illustrated configuration positions the post member 130 primarily above the carriage 1120, with the telescoping column extending downward through a cutout in the upper platform 110 and terminating at a forward-extending foot member beneath that upper platform 110 when it is arranged in an elevated position. In this orientation, the actuator extends downward to lower the carriage 1120 and retracts upward to raise it, allowing the column to clear the working envelope as the carriage descends. This geometry permits substantially lower working elevations than the under-carriage push configuration, enabling floor-seated operation while maintaining guided, stable motion within the enclosure 1110 and preserving a compact fore-aft profile for stowage.

[0245] While the adjustable desk assembly illustrated in FIGS. 11A-11F, 12, and 13A-13C, is shown in a wall-mounted configuration, numerous modifications are possible. In some embodiments, the enclosure and platform carriage can be integrated with a stationary desk assembly, such as a frame-based structure or a leg-supported structure similar to the embodiments shown in FIGS. 7A and 7B, where the mounting interface couples the enclosure to a desk frame, a rear wall panel, or a cross member. In other embodiments, the assembly can be adapted for mobile use, for example by coupling the enclosure to a wheeled base, cart, or movable frame as in FIG. 8, allowing the unit to be repositioned within a room or transported between rooms while preserving the same guided vertical motion and compacted stowage features. Additionally, as explained above the size, shape, dimensions, and materials of the upper platform 110, lower platform 120, post member 130, and platform adjustment assemblies 150 can be varied. These alternative integrations may utilize various brackets, fasteners, or support members and can accommodate variations in footprint, height, and load distribution without departing from the operability of the carriage, the guidance structures, or the height-adjustable extension member described herein.
