[0035] In commercial laundry and uniform service operations, used hangers may be collected from customer locations after garment delivery and transported back to processing facilities for reuse. Hanger collection and transportation in commercial laundry and uniform service operations presents several challenges that can impact operational efficiency. Dunng collection processes at customer facilities, hangers frequently become disorganized and tangled together, creating difficulties in handling and processing. Hangers collected from locker rooms, changing areas, and other customer locations often accumulate in random orientations, with hooks facing different directions and hanger bodies intertwined with one another. This disorganization can lead to increased handling time and potential damage to both hangers and garments during subsequent processing steps.

[0036] The physical handling of disorganized hangers presents ergonomic challenges for service technicians and processing personnel. Workers often spend considerable time manually sorting and reorienting hangers to achieve uniform positioning for efficient processing and reuse. This manual sorting process can require repetitive motions, awkward positioning, and extended periods of handling individual hangers. The timeconsuming nature of hanger sorting also reduces overall operational efficiency and increases labor costs associated with hanger management processes.

[0037] Transportation of collected hangers from customer sites to service vehicles and processing facilities introduces additional complications related to hanger organization and security'. Loose hangers can shift, tangle, and become further disorganized during transport, particularly when loaded into vehicles without adequate containment systems. The movement and vibration associated with vehicle transport can cause hangers to slide around cargo areas, potentially making subsequent unloading and processing more difficult. Hangers that become entangled during transport can also be damaged or rendered unusable, leading to increased replacement costs and waste.

[0038] Storage constraints in service vehicles and processing facilities can compound these organizational challenges. Limited space in service trucks and storage areas can makeproper hanger organization difficult to maintain, particularly when dealing with large quantities of collected hangers. The lack of dedicated storage systems designed specifically for hanger organization can result in hangers being stored in ways that promote tangling and disorganization. These storage limitations can also make loading and unloading processes more time-consuming and physically demanding for service personnel.

[0039] Therefore, it can be desirable to provide a device that easily organizes hangers into correct orientation during initial collection processes. It may be desirable for such a device to streamline the collection w orkflow by encouraging proper hanger placement from the outset, reducing the need for subsequent manual sorting and reorientation activities. It can be desirable to incorporate design features that naturally guide users to position hangers in a consistent manner, eliminating much of the randomness that typically characterizes hanger collection in commercial sen-ice environments. By establishing proper hanger orientation at the point of collection, the device can significantly reduce the labor-intensive sorting processes that traditionally occur at processing facilities.

[0040] It can also be desirable to provide a device that facilitates easy transportation of used hangers from customer locations to service trucks and subsequently to processing facilities. It may be desirable for such a device to incorporate mobility features that enable service technicians to efficiently move collected hangers through various environments, including navigating doorways, corridors, and loading areas commonly encountered during service operations. Transportation efficiency can be enhanced through design elements that accommodate the physical constraints of service vehicles while maintaining hanger organization throughout the movement process. It may be desirable for such a device to address ergonomic considerations by reducing the physical strain associated with lifting, carrying, and maneuvering large quantities of hangers during collection and transportation activities.

[0041] Furthermore, it can be desirable to provide a device that maintains hanger organization during transportation between locations. It may be desirable for such a device to incorporate securing mechanisms that prevent hanger movement, tangling, and disorganization that commonly occur during vehicle transport. These securing features can address the vibration and movement challenges associated with road transport, ensuring that hangers remain in their intended positions throughout the journey from customer sites to processing facilities. It may be desirable for such a device to also accommodate the varying quantities of hangers typically encountered in commercial service operations while maintaining organizational integrity regardless of load size.

[0042] Additionally, it can be desirable to provide a device that minimizes truck space usage while maximizing hanger storage capacity. Space optimization can be achieved through design features that allow multiple devices to be efficiently arranged within service vehicle cargo areas. It may be desirable for such a device to incorporate collapsible or nestable elements that reduce storage volume when not actively loaded with hangers, enabling service technicians to transport multiple devices without consuming excessive vehicle space. Efficient space utilization can also extend to processing facility storage areas, where multiple devices can be organized in compact configurations during periods of non-use. It may be desirable for such a device to balance space efficiency with accessibility, ensuring that hangers remain easily retrievable for processing operations while minimizing the overall footprint required for storage and transportation activities.

[0043] The present disclosure provides several examples of various portable hanger rack assemblies that can, for example, address one or more of the foregoing. For example, FIGS. 1 and 5A-5H illustrate a portable hanger rack assembly (100). As will be described in greater detail below, portable hanger rack assembly (100) can address the technical challenges associated w ith hanger collection, organization, and transportation in commercial service environments. Therefore, portable hanger rack assembly (100)can thus be configured to facilitate easy transportation of used hangers to service trucks and subsequently to processing facilities.

[0044] Portable hanger rack assembly (100) is shown to include a structural framework in the form of a frame (102), a support mechanism in the form of a collapsible stand assembly (110), a stabilizing mechanism in the form of a kickstand (130). hanger support structures in the form of hanger racks (140), and securing mechanisms in the form of hanger locks (150) which are each associated with a respective hanger rack (140). As will be described in greater detail below, frame (102), collapsible stand assembly (110), and kickstand (130) can be configured to enable portable hanger rack assembly (100) to transition between a collapsed configuration and a self-standing configuration, to thereby enable portable hanger rack assembly (100) to minimize its spatial presence when not in use while being easily maneuverable when in the self-standing configuration. As will also be described in greater detail below, hanger racks (140) can be configured to facilitate easy organization of hangers during initial collection of used hangers; while hanger locks (150) can be configured to maintain the position and orientation of hangers supported on hanger racks (140) during suitable transportation of portable hanger rack assembly (100) in accordance with the description herein.

[0045] Frame (102) can provide a support structure for portable hanger rack assembly (100).Frame (102) includes a base (104) positioned at the low er portion of the assembly to provide stability and support during operation. Base (104) can be configured to engage the ground in order to provide such stability and support when portable hanger rack assembly (100) is in the self-standing configuration. Frame (102) is also shown to include vertical bars (106) extending upward from base (104). Vertical bars (106) may extend parallel relative to each other as shown or, alternatively, may have any other suitable spatial relationship relative to each other as would be apparent to one skilled in the art in view7of the teachings herein. A handlebar (108) is shown to connect vertical bars (106) at an upper portion of frame (102) to facilitate manual manipulation andtransportation of portable hanger rack assembly (100) in accordance with the description herein.

[0046] Frame (102) may be constructed from any suitable material or combination thereof, including but not limited to metal, plastic, composite materials, or other rigid structural materials, as would be apparent to one skilled in the art in view of the teachings herein. In some instances, handlebar (108) may include ergonomic gripping structures, textured surfaces, cushioned elements, or contoured portions to enhance user comfort and control during manipulation of portable hanger rack assembly (100).

[0047] As described above, collapsible stand assembly (110) can facilitate transition of the portable hanger rack assembly (100) between a collapsed, compact folded configuration (see FIG. 5A) and an expanded, self-standing configuration (see FIGS.1, and 5D-5H). Collapsible stand assembly (110) is shown to include a pair of legs (112) that extend from frame (102) to provide additional support when portable hanger rack assembly (100) is positioned in an extended, self-standing configuration (see FIGS. 1, 5D-5H). In the current example, each of legs (112) is shown to be pivotally attached to a respective vertical bar (106) of frame (102) about a pivot axis (Al) via a respective bracket (117) and pivot (115). This pivotal connection enables legs (112) to rotate relative to frame (102), allowing portable hanger rack assembly (100) to transition smoothly between the compact folded configuration and the extended selfstanding configuration. The pivotal attachment mechanism facilitates controlled movement while maintaining structural integrity in both configurations. While in the current example, two legs (112) are present, it should be understood that any suitable number of legs may be used as would be apparent to one skilled in the art in view of the teachings herein.

[0048] A retention bar (120) is show n to be fixed to each leg (112) and to include a first detent (122) and a second detent (124). The retention bar (120) and leg (112) are shown to together define a slot (118) that provides a guided pathway for operational components (e.g., kickstand (130)) to control the pivotal position of legs (112) relative to frame(102). As will be described in greater detail below, slot (118) slidably houses a portion of kickstand (130), enabling controlled movement between different operational positions associated with at least the compact configuration and the self-standing configuration. First detent (122) and second detent (124) help maintain portable hanger rack assembly (100) in the compact configuration and the self-standing configuration, respectively, by providing discrete positioning points that resist inadvertent movement while allowing intentional transitions between operational states (e g., the collapsed, compact folded configuration and the expanded self-standing configuration). This detent system may enhance operational stability by creating positive engagement positions that correspond to the primary use configurations of the assembly (e.g., the compact configuration and the self-standing configuration). In one embodiment, as illustrated, each respective leg (112) of the portable hanger rack assembly (100) can be fitted with a respective retention bar (120) to facilitate the aforementioned operation of the kickstand (130), though in other embodiments, only one leg of a portable hanger rack assembly might be fitted with a retention bar.

[0049] Each leg (112) can terminate in an angled end (113) that attaches to an axle (116) supporting wheels (114). Wheels (114) are configured to rotate about their axis in order to allow portable hanger rack assembly (100) to be easily transported to suitable locations as would be apparent to one skilled in the art in view of the teachings herein (e.g., a customer facility, atruck, and a processing center). Wheels (114) connect to leg (112) through axle (116), enabling a user to easily tilt and roll portable hanger rack assembly (100) in the self-standing configuration. While two wheels (114) are used in the current example, any suitable number of wheels may be incorporated as would be apparent to one skilled in the art in view of the teachings herein. One or more wheels may be associated with any suitable component of portable hanger rack assembly (100), including, but not limited to base (104) of frame (102). In the current example, wheels (114) pivot about a fixed axis; however, other suitable wheel configurations may be used, such as swivel wheels, casters, or other rotatable wheel mechanisms.

[0050] Wheels (114) facilitate smooth transportation of portable hanger rack assembly (100) across various surface types, even when supporting a substantial load of hangers. The balanced design distributes weight effectively, allowing users to maneuver the fully- loaded rack with minimal effort while maintaining the secure orientation of hangers during transport.

[0051] The angled end (113) of leg (112) can be configured to position wheel (114) closer toward frame (102) when portable hanger rack assembly (100) is in the self-standing configuration. This positioning allows portable hanger rack assembly (100) to be more easily lifted up / down stairs, such as stairs of a vehicle, without having wheels (114) excessively bump against the stairs. In some instances, angled end (113) may be angled to such a degree that the periphery of wheel (114) is inhibited from bumping against stairs during such movement, allowing leg (112) to absorb the impact instead. This configuration enhances maneuverability in multi-level environments while maintaining structural integrity during transportation activities.

[0052] Kickstand (130) can be configured to enable easy transitioning of portable hanger rack assembly (100) between the compact configuration and the self-standing configuration. Further, kickstand (130) can provide additional support when portable hanger rack assembly (100) is in the self-standing configuration. Kickstand (130) includes two pivot arms (132) (one shown) that are coupled to each other via a lateral connecting bar (134). Pivot arms (132) can pivotally connect to vertical bars (106) of frame (102) about pivot axis (A2) via a pivot (135) and bracket (137) arrangement that enables rotational movement of kickstand (130) between a retracted position (associated with portable hanger rack assembly (100) in the compact configuration) and a deployed position (associated with portable hanger rack assembly (100) in the self-standing configuration). A portion of kickstand (130) is shown to be slidably housed within slot (118) defined by leg (112) and retention bar (120), and this interaction defines the pivotal position of leg (112) relative to frame (102) in response to the pivotal position of kickstand (130) relative to frame (102) and legs (112).

[0053] Therefore, in the compact configuration shown in FIG. 5A, both kickstand (130) and legs (112) are positioned in a retracted orientation that minimizes the overall footprint of portable hanger rack assembly (100). Both pivot arms (132) and legs (112) are closely aligned with vertical bars (106), reducing the space occupied by the assembly during transportation and storage activities. This compact arrangement enables multiple portable hanger rack assemblies (100) to be efficiently organized within service vehicles and storage areas without consuming excessive space.

[0054] As shown in FIGS. 5B-5D, kickstand (130) can transition to a deployed configuration, which in turn also pivots legs (112) into a respective deployed position to thereby establish the self-standing configuration of portable hanger rack assembly (100). In such atransition, both pivot arms (132) and legs (112) rotate outward from vertical bars (106) to create a stable triangular support structure that prevents portable hanger rack assembly (100) from tipping during hanger collection and organization activities.

[0055] As mentioned above, retention bar (120) includes first and second detents (122, 124).First and second detents (122, 124) interact with kickstand (130) to provide a detent locking mechanism that can retain portable hanger rack assembly (100) in either the compact folded configuration (see FIG. 5A) or the self-standing configuration (see FIG. 1 and 5D-5H). The engagement between kickstand (130) and the respective detents (122, 124) creates resistance that prevents portable hanger rack assembly (100) from unintentionally transitioning between the compact folded configuration and the self-standing configuration during transport or use.

[0056] First detent (122) can engage kickstand (130) when positioned in the retracted configuration, which can help maintain portable hanger rack assembly (100) in the compact folded position. Second detent (124) can engage kickstand (130) when positioned in the deployed position, which can help maintain portable hanger rack assembly (100) in the self-standing configuration. The dimensions and configuration of detents (122, 124) and kickstand (130) are intended to provide sufficient resistance to prevent inadvertent transitions between the folded and self-standing configurationswhile still allowing a user to deliberately overcome this resistance by applying appropriate force when a configuration change is desired. Therefore, the interaction between detents (122, 124) of retention bar (120) and kickstand (130) creates positive engagement positions that resist inadvertent movement while allowing intentional transitions between retracted and deployed positions of kickstand (130).

[0057] A user may use their foot or other portion of their body to engage lateral connecting bar (134) and / or pivot arms (132) while simultaneously pulling on handle bar (108) in order to pivot kickstand (130) about pivot axis (A2) relative to frame (102) in accordance with the description herein, providing an ergonomic means of adjusting the configuration of portable hanger rack assembly (100) between the collapsed configuration (see FIG. 5 A) and the self-standing configuration (see FIG. 1 and 5D- 5H). The coordinated action of engaging the kickstand (130) while pulling on handlebar (108) can promote efficient pivotal movement of the kickstand (130) with minimal effort from the user. The combination of collapsible stand assembly (110) and kickstand (130) enables portable hanger rack assembly (100) to achieve stable positioning during hanger collection activities while also allowing the assembly to be configured in a compact arrangement for transportation and storage when not actively supporting hangers.

[0058] While in the current example, leg (112) and retention bar (120) define slot (118) that slidably houses a portion of kickstand (130), it should be understood that alternative configurations may be employed as would be apparent to one skilled in the art in view of the teachings herein. In some instances, kickstand (130) may define a slot that houses leg (112) in order to allow kickstand (130) to slide along a predetermined path defined by leg (112). This alternative arrangement may provide similar functionality while offering different structural advantages or manufacturing considerations.

[0059] The sliding engagement between a kickstand (e g., 130) and a leg (e.g., 112), regardless of which component defines the slot, enables controlled movement along a guided pathway that coordinates the positioning of both components during transitionsbetween the compact and self-standing configurations. This sliding relationship may facilitate smooth operation while maintaining proper alignment of the components throughout their range of motion.

[0060] In some instances, detents such as first detent (122) and second detent (124) may be present to provide discrete positioning points that enhance operational stability. However, it should be understood that detents may or may not be present in various embodiments, as the sliding engagement between kickstand (130) and leg (112) may provide sufficient positioning control without requiring additional detent features. When detents are omitted, the sliding mechanism may rely on friction, spring tension, or other retention methods to maintain desired positions. Alternatively, some embodiments may incorporate different types of positioning mechanisms, such as cam surfaces, ratcheting features, or magnetic retention systems, to achieve similar positioning control while offering distinct operational characteristics.

[0061] Hanger racks (140) in the current example are shown to be fixed to, and extend in a horizontal direction from, vertical bars (106). Each hanger rack (140) is configured to receive and organize hangers during collection processes. Hanger racks (140) position hangers in a uniform orientation to inhibit the random positioning that often occurs during conventional hanger collection activities.

[0062] In the current example, as shown in FIG. 2, hanger racks (140) include a hook receiving wall (142) and a neck receiving wall (144), thereby forming a J-shaped configuration that facilitates proper hanger orientation during collection activities. As at least shown in FIGS. 6A-6B, hook receiving wall (142) has a complementary profile dimensioned to support a hook (4) of each supported hanger (2); while neck receiving wall (144) has a complementary profile dimensioned to support and / or align a neck (6) of each supported hanger (2). Neck receiving wall (144) can be attached to vertical bars (106) such that the terminating end of hook receiving wall (142) faces away from a user when portable hanger rack assembly (100) is in the self-standing configuration.

[0063] The J-shaped design creates a curved receiving area that naturally guides hangers into a consistent positioning arrangement when placed on portable hanger rack assembly (100). This curved configuration substantially simplifies the process of hanging postuse hangers in the correct orientation by providing an intuitive physical pathway that makes proper placement significantly easier than incorrect placement. If a user were to attempt hanging a post-use hanger in the incorrect orientation, they would need to awkwardly access the portable hanger rack assembly (100) from the rear side, which would be tilted at a difficult angle that creates ergonomic challenges. The J-shaped geometry' establishes a receiving channel that not only accommodates hanger hooks but actively discourages improper orientation by making the correct hanging position naturally accessible from the front while making incorrect positioning physically inconvenient and counterintuitive.

[0064] As shown in FIGS. 6A and 6B, a hanger (2) includes a hook (4), a neck (6), and arms (8) that extend from neck (6) to support garments. Hook (4) connects to neck (6) and provides a curved structure for suspending hanger (2) on various support systems. Arms (8) extend laterally from neck (6) to provide garment support surfaces during use. When hanger (2) is positioned on hanger rack (140), hook (4) engages with a hook receiving wall (142) while neck (6) aligns with a neck receiving wall (144). Hook receiving wall (142) provides a curved support surface that accommodates hook (4) and maintains hanger (2) in a consistent orientation. Neck receiving wall (144) extends from hook receiving wall (142) to create a J-shaped configuration that guides proper hanger placement and prevents incorrect orientation during collection activities.

[0065] While the J-shaped design of hanger racks (140) is used in the current example, any suitable shape may be employed as would be apparent to one skilled in the art in view of the teachings herein. For example, a U-shaped design may be used and may rely on the position of the rack to encourage users to correctly orient post -use hangers. In such a configuration, the fact that a user would have to awkwardly access the rack from the underside in order to inappropriately hang a hanger creates a natural deterrent toimproper placement. The U-shaped geometry may establish an upward-facing receiving channel that makes correct hanger placement intuitive and ergonomically favorable when accessed from the front or sides, while making incorrect placement physically inconvenient and counterintuitive.

[0066] Other suitable configurations may include L-shaped designs, curved profiles, or angular arrangements that similarly leverage ergonomic principles to guide proper hanger orientation. Consideration in such designs may include creating a physical configuration that makes correct hanger placement the most natural and accessible option while making incorrect placement awkward or difficult to achieve. This approach may help ensure consistent hanger orientation without requiring complex mechanical guidance systems or extensive user training.

[0067] The specific shape and orientation of hanger racks (140) may be selected based on factors such as manufacturing considerations, material properties, space constraints, or specific operational requirements. Regardless of the particular geometric configuration employed, hanger racks in accordance with the present disclosure can provide a receiving structure that naturally encourages proper hanger orientation through intuitive physical design rather than relying solely on user instruction or mechanical enforcement.

[0068] Portable hanger rack assembly (100) is shown to include more than one hanger rack (140) to accommodate varying quantities of hangers encountered during commercial service operations. More particularly, in some instances, portable hanger rack assembly (100) can include two, three or more hanger racks (140) positioned at different vertical levels along vertical bars (106). This multi-level arrangement maximizes the hanger capacity of portable hanger rack assembly (100) while maintaining the organizational benefits provided by the J-shaped configuration of each individual hanger rack (140). The spacing between multiple hanger racks (140) allows for adequate clearance between hangers positioned on different levels, preventing interference during loadingand unloading activities. In other embodiments, a portable hanger rack assembly might include only a single hanger rack.

[0069] Each hanger rack (140) can be associated with a securing mechanism in the form of a respective hanger lock (150). Hanger locks (150) can be configured to transition between an unlocked configuration (see FIG. 6A) and a locked configuration (see FIG.6B) in order to (a) allow post-use hangers to be placed on a respective rack (140) in the unlocked configuration, and then (b) control hanger movement during transportation in the locked configuration. While in the current illustrative example, hanger locks (150) pivot relative to frame (102) to engage with hangers positioned on hanger racks (140), it should be understood that hanger locks may alternatively be configured to translate, slide, or employ some combination of translation, rotation and / or other movement in order to transition between the unlocked and locked configurations. For example, a track may be provided on a frame that guides hanger locks along a predetermined path between the unlocked and locked configurations. In other instances, hanger locks may incorporate a telescoping mechanism that extends and retracts to engage with hangers. Alternatively, hanger locks may utilize a sliding collar that moves linearly along a fixed rod to secure hangers in place. In yet other examples, hanger locks may employ a cam-actuated mechanism that converts rotational input into linear movement to engage hangers. The specific movement profile of hanger locks may be selected based on ergonomic considerations, space constraints, or manufacturing preferences, while still achieving the function of preventing hanger movement and maintaining organizational integrity during transport between customer locations and service vehicles.

[0070] Referring to FIG. 4, in the current illustrative example, each hanger lock (150) includes a mount arm (152), a pivoting bar (160), and a folded sheath (170) that work together to selectively secure hangers positioned on hanger rack (140). Mount arm (152) provides a structural foundation for hanger lock (150) and includes a pair of securedends (154) that fixedly attach to a respective vertical bar (106) of frame (102). Therefore, in the current example, mount arm (152) can be fixed relative to frame (102).

[0071] Mount arm (152) further includes two locking surfaces (156). As will be described in greater detail below, locking surfaces (156) can be positioned to selectively engage with a respective locking surface (166) of pivoting bar (160) in order to selectively lock pivoting bar (160) and folded sheath (170) into the locked configuration (see FIG. 6B). Mount arm (152) further includes a crossbar (158) that extends between locking surfaces (156) to provide additional structural support and connection points for other components of hanger lock (150). Mount arm (152) establishes a fixed reference point from which other components of hanger lock (150) can pivot and move relative to frame (102) during locking and unlocking operations.

[0072] Pivoting bar (160) connects to mount arm (152) via respective pivot couplings (162) that enable rotational movement of pivoting bar (160) relative to mount arm (152) between the unlocked configuration (see FIG. 6A) and the locked configuration (see FIG. 6B). In the current example, each pivot coupling (162) comprises an end of pivoting bar (160) that is wrapped around crossbar (158) to create a hinged connection. This wrapped configuration allows pivoting bar (160) to rotate relative to mount arm (152) while maintaining structural integrity during repeated operational cycles. While the current example utilizes this wrapped configuration, other suitable structures may provide such pivotal or otherwise movable coupling as would be apparent to one skilled in the art in view of the teachings herein. For example, a pivot coupling may alternatively comprise a pin-and-hole arrangement, a living hinge formed of flexible material, a ball-and-socket joint, or other suitable mechanical coupling that enables controlled movement between components. In some instances, a pivot coupling may incorporate bearings, bushings, or low-friction materials to enhance operational smoothness and durability7over extended use periods.

[0073] Pivoting bar (160) is shown to include a respective sheath mounting arm (164) that extends from each pivot coupling (162) and provides attachment points for foldedsheath (170). In the current example, sheath mounting arms (164) can be mounted to folded sheath (170) via welding. However, it should be understood that sheath mounting arms (164) and folded sheath (170) can be attached via any suitable means as would be apparent to one skilled in the art in view of the teachings herein. For instance, sheath mounting arms (164) and folded sheath (170) may be attached via mechanical fasteners, adhesives, snap-fit features, or other suitable coupling mechanisms.

[0074] Each sheath mounting arm (164) is show n to incorporate a respective locking surface (166) that corresponds with a locking surface (156) of mount arm (152) described above. In particular, respective locking surfaces (156, 166) can be configured to engage each other when pivoting bar (160) and folded sheath (170) transition into the locking configuration in accordance with the description herein. This engagement can promote a frictional braking force that inhibits pivoting bar (160) and folded sheath (170) from inadvertently pivoting out of the locked configuration relative to mount arm (152) and frame (102). If portable hanger rack assembly (100) experiences forces during transit while in the locked position, the engagement between locking surfaces (156, 166) can maintain hanger lock (150) in the locked configuration in accordance with the description herein, which in turn can keep hangers associated with hanger rack (140) inhibited from moving relative to hanger rack (140). This secure engagement ensures that even during transportation over uneven surfaces or when subjected to sudden movements, the hangers remain properly oriented and substantially securely positioned, thereby maintaining organizational integrity throughout the entire transport process. If a user wants to transition hanger lock (150) from the locked configuration into the unlocked configuration, they can pull on lip (176) of folded sheath (170) (or another suitable portion of hanger lock (150)) with sufficient force to overcome the frictional braking force, thereby intentionally actuating hanger lock (150) into the unlocked configuration.

[0075] Pivoting bar (160) is also shown to include a first hanger contact surface (168). First hanger contact surface (168) extends across a portion of hanger rack (140) that is configured to support hangers (2). thereby enabling first hanger contact surface (168) to suitably engage supported hangers when hanger lock (150) transitions to the locked configuration. In some examples, first hanger contact surface (168) may span substantially the entire length of the hanger-supporting portion of hanger rack (140), providing comprehensive engagement with multiple hangers (e.g., all hangers supported by hanger rack (140)) simultaneously. In some embodiments, the surface profile of first hanger contact surface may be configured to complement the geometry of typical hanger components, such as hooks (4) or necks (6), to enhance the securing effectiveness when the locking mechanism is engaged.

[0076] As will be described in greater detail below; first hanger contact surface (168) of pivoting bar (160) and a portion of folded sheath (170) (e.g., second hanger contact surface (178)) can be configured to simultaneously contact different locations of hangers (2) supported on an associated hanger rack (140) to thereby further promote stability of such supported hangers (2) relative to hanger rack (140) during transportation while hanger lock (150) is in the locked configuration. This dual -contact arrangement distributes securing forces across multiple points on the hangers (2), inhibiting movement and maintaining proper orientation of supported hangers (2) relative to hanger rack (140) throughout transport operations.

[0077] Folded sheath (170) is shown in FIG. 4 to include a first wall (172) and a second wall (174) that create a folded configuration. As mentioned above, folded sheath (170) and pivoting bar (160) can be fixed to each other via sheath mounting arm (164) being mounted to first wall (172). Therefore, folded sheath (170) can be configured to pivot with pivoting bar (160) relative to mount arm (152) between the unlocked and locked configurations, enabling the coordinated movement of these components to effectively secure hangers when transitioning to the locked configuration. It will be appreciated that, while hanger lock (150) is in the locked configuration, as illustrated at least inFIG. 6B, folded sheath (170) can cooperate with hanger rack (140) to define a cavity which houses a hook (4) and at least a portion of neck (6) of hanger (2) supported on hanger rack (140).

[0078] Referring again to FIG. 4, a terminating portion of second wall (174) is shown to include second hanger contact surface (178) which then extends further into lip (176). As mentioned above, lip (176) may provide a grasping area suitable to allow a user to easily transition hanger lock (150) from the locked configuration into the unlocked configuration. First hanger contact surface (168) and second hanger contact surface (178) can be positioned to engage different portions of hangers when hanger lock (150) is in a locked configuration. For example, as illustrated in FIG. 6B, first hanger contact surface (168) can be configured to engage hanger (2) at a location adjacent to where hook (4) and neck (6) meet, while second hanger contact surface (178) can be positioned to contact the junction where neck (6) meets arms (8). This dual-contact arrangement creates a distributed securing force that effectively presses hanger (2) against neck receiving wall (144) and a deformable body (180). The compression of hanger (2) towards neck receiving wall (144) and deformable body (180) can cause deformable body (180) to elastically yield, creating a cushioned, secure fit that substantially prevents movement of hanger (2) during transportation activities. It will be appreciated that these different portions of hanger (2) which are engaged can be separate and spaced from one another.

[0079] In the current example, pivoting bar (160) and folded sheath (170) are formed from different components that are fixed to each other such that first and second hanger contact surfaces (168, 178) are also formed from different components that are fixed to each other during assembly. However, alternatively, a pivoting bar and folded sheath may be formed as a single piece of material, or at least first and second hanger contact surfaces can be formed from a single piece as a unitary' structure. For instance, pivoting bar and folded sheath (170) may be extruded, 3D printed, injection molded, or otherwise formed as a single unitary component. Forming these components as a singlepiece can potentially provide tolerance benefits, including eliminating stack-up tolerances between separately manufactured parts, ensuring consistent alignment between the first and second hanger contact surfaces, reducing manufacturing variability, and maintaining more precise engagement with hangers. This single-piece construction can also enhance durability by eliminating potential failure points at connection interfaces while simplifying assembly and reducing the number of components that must be inventoried and tracked during manufacturing. Alternatively, one or more of a pivoting bar and a folded sheath may each comprise more than two pieces that are assembled together. For example, such a folded sheath may include multiple segments that are joined together and then attached to a pivoting bar. and / or such a pivoting bar may include multiple segments that are joined together and then attached to a folded sheath.

[0080] Pivoting bar (160) and / or folded sheath (170) may be formed from any suitable material or combination of materials as would be apparent to one skilled in the art in view of the teachings herein. In some embodiments, these components may be constructed from metallic materials such as steel, aluminum, stainless steel, or other metal alloys that provide structural strength and durability for repeated operational cycles. The metallic construction may offer advantages in terms of wear resistance and maintaining dimensional stability under mechanical stress during locking and unlocking operations.

[0081] In some cases, pivoting bar (160) and / or folded sheath (170) may be formed from polymeric materials such as thermoplastics, thermosets, or engineered plastics. Suitable polymeric materials may include polyethylene, polypropylene, nylon, polycarbonate, ABS (acrylonitrile butadiene styrene), or other plastic materials that provide adequate strength while potentially offering benefits such as corrosion resistance, lighter weight, and cost-effective manufacturing. The polymeric construction may also facilitate various manufacturing processes such as injection molding, extrusion, or 3D printing.

[0082] In some instances, pivoting bar (160) and / or folded sheath (170) may incorporate composite materials that combine different material properties to achieve desired performance characteristics. For example, fiber-reinforced plastics may provide enhanced strength-to-weight ratios, while metal-plastic hybrid constructions may offer both structural integrity and design flexibility.

[0083] The material selection may also consider factors such as environmental conditions, chemical compatibility’, temperature resistance, and aesthetic requirements. In some cases, different portions of pivoting bar (160) and folded sheath (170) may be formed from different materials to optimize specific functional requirements. For instance, contact surfaces may be formed from materials with specific friction or wear characteristics, while structural portions may prioritize strength and rigidity'.

[0084] Surface treatments or coatings may also be applied to pivoting bar (160) and folded sheath (170) regardless of the base material selection. Such treatments may include anodizing, powder coating, plating, or other finishing processes that enhance corrosion resistance, appearance, or functional properties of the components.

[0085] As shown in at least FIGS. 2-3 and 6A-6B, deformable body (180) can be positioned between folded sheath (170) and neck (6) of hanger (2) when hanger lock (150) is in a locked configuration. Deformable body (180) can include elastically deformable material that compresses when hanger lock (150) engages hanger (2), creating a secure connection that inhibits hanger movement during transportation. The elastically deformable material of deformable body (180) conforms to variations in hanger dimensions and geometries while promoting a substantially consistent securing pressure across different hanger ty pes. Deformable body (180) can include foam padding, elastomeric material, etc., that elastically deforms when engaging hangers and contributes to inhibiting vibrations during transportation by absorbing movement and providing cushioned contact between hanger lock (150) and hanger (2). The foam padding, elastomeric material, etc., creates a resilient interface that accommodatesrepeated compression cycles while maintaining securing effectiveness over extended operational periods.

[0086] Deformable body (180) facilitates enhanced engagement of portions of hangers (2) located between hanger lock (150) and hanger rack (140), particularly at neck (6) of hanger (2), ensuring secure retention while preventing damage to hanger (2) during securing operations. The deformable characteristics enable deformable body (180) to capture hangers when hanger locks (150) are engaged while reducing or preventing hanger movement and rattling that can otherwise occur during vehicle transport between customer locations and processing facilities.

[0087] As at least shown in FIG. 3, deformable body (180) can be attached to neck receiving wall (144) of hanger rack (140). The deformable body (180) can extend along at least a portion of the hanger rack (140) that is intended to engage and support hangers (2). As shown in FIG. 3, the deformable body (180) can extend along the entirety or nearly the entirety of the hanger rack (140). This placement ensures that deformable body (180) is in contact with hangers (2) during use.

[0088] Deformable body (180) can be configured for removable attachment to neck receiving wall (144) of hanger rack (140), facilitating straightforward replacement when wear eventually occurs. Various coupling mechanisms may be employed to secure the deformable body (180) to neck receiving wall (144) of hanger rack (140), including but not limited to adhesive bonding, mechanical fastening systems, or resilient clip structures that engage with corresponding features on neck receiving wall (144) or another portion of the hanger rack (140).

[0089] A deformable body may additionally or alternatively be incorporated into or associated with first hanger contact surface and / or second hanger contact surface in addition to or as an alternative to association of deformable body (180) with neck receiving wall (144). A deformable body may additionally or alternatively be incorporated into or associated with a hanger lock (e.g., second wall 174 of folded sheath 170) in addition to or as an alternative to association of deformable body (180) with neck receiving wall(144). This configuration may also provide cushioning and securing capabilities at the specific contact points where hanger lock (150) engages with hangers during locking operations.

[0090] The deformable body (180) may be configured with any suitable shape or configuration as would be apparent to one skilled in the art in view of the teachings herein. The specific geometry of deformable body (180) may be selected based on the particular contact surface configuration, the types of hangers being secured, and the desired securing characteristics. In some embodiments, the shape of a deformable body may be optimized to complement the contours of the contact surfaces and provide uniform pressure distribution across the engagement area.

[0091] In instances where a deformable body is configured to couple with or itself provide a first hanger contact surface (e.g., like 168) and / or second hanger contact surface (e.g., like 178), the deformable body may take various forms. For example, the deformable body may comprise a cylindrical or tubular configuration that can be positioned along the length of or otherwise itself provide the contact surfaces. This tubular arrangement may provide consistent cushioning along the entire engagement zone while accommodating hangers of different sizes and configurations.

[0092] Alternatively, a deformable body may be formed in a curved or arcuate shape that follows the contour of the contact surfaces. In some cases, a deformable body may comprise a channel-shaped or groove-like configuration that can receive and cushion portions of the hangers during engagement. The deformable body may also be configured with a multi-lobed or segmented design that provides targeted cushioning at specific contact points.

[0093] In some implementations, a deformable body may be designed for temporary or removable attachment to first hanger contact surface (168) and / or second hanger contact surface (178). This removable configuration may facilitate maintenance operations, replacement of worn components, and cleaning activities. The attachment mechanism may include various coupling features such as snap-fit connections,friction-fit arrangements, or mechanical fastening systems that allow the deformable body to be easily installed and removed as needed.

[0094] The removable nature of deformable body (180) may also enable the use of different deformable materials or configurations depending on specific operational requirements. For instance, different durometer materials may be selected for different applications, or specialized surface textures may be incorporated to enhance gripping characteristics with particular hanger types.

[0095] Referring to FIGS. 5A-5H, portable hanger rack assembly (100) can be used in commercial laundry and uniform service operations to facilitate efficient hanger collection and transportation processes. Service technicians can utilize portable hanger rack assembly (100) to streamline collection workflows while maintaining proper hanger orientation throughout the entire process from customer facilities to processing centers.

[0096] During initial delivery to customer locations, portable hanger rack assembly (1 0) can be transported in a compact, folded configuration as shown in FIG. 5A. This folded arrangement minimizes the spatial footprint of portable hanger rack assembly (100) during transport to customer sites, enabling service technicians to efficiently load multiple units into service vehicles without consuming excessive cargo space.

[0097] Upon arrival at customer facilities, service technicians can transition portable hanger rack assembly (100) from the compact configuration to a self-standing configuration, as shown sequentially from FIGS. 5A-5D. More particularly, the transition process can involve a service technician initially pivoting kickstand (130) and applying force to overcome resistance provided by first detent (122). Kickstand (130) can then be further moved about pivot (135), which simultaneously causes legs (112) to rotate outward from vertical bars (106), while other portions of kickstand (130) slidingly move within slots (118). As shown in FIG. 5C. as kickstand (130) moves toward the deployed position, second detent (124) initially engages with kickstand (130). The service technician may then further pivot kickstand (130) to overcome the resistanceprovided by second detent (124) to achieve the self-standing configuration shown in FIG. 5D. In the self-standing configuration, base (104) and wheels (114) support portable hanger rack assembly (100) via engagement with a ground or floor surface. This deployment creates a triangular support structure that provides stability during hanger collection activities while positioning wheels (114) to facilitate subsequent transportation.

[0098] With portable hanger rack assembly ( 100) positioned in the self-standing configuration, sendee technicians can begin the hanger collection process at customer locations. As shown in FIG. 5E. service technicians can pivot hanger locks (150) into the unlocked position such that hanger racks (140) may receive post-use hangers (2) as shown in FIG. 5F and in accordance with the description herein. In some instances, end users, rather than service technicians, may actuate hanger lock (150) between the locked and unlocked positions to enable rack (140) to receive hangers (2). This flexibility7allows for efficient collection of hangers regardless of whether service personnel or end users are operating the portable hanger rack assembly (100).

[0099] As shown in FIG. 5F, portable hanger rack assembly (100) can receive and support a plurality of hangers such that hooks are oriented in a uniform direction throughout the collection process. Each hanger rack (140) is specifically dimensioned to accommodate multiple hangers simultaneously, maximizing storage efficiency while maintaining proper spacing between individual hangers. The J-shaped design of hanger racks (140) predisposes users to hang post-use hangers in a particular orientation by providing a receiving channel that accommodates hanger hooks while actively discouraging improper placement. When multiple hangers are positioned on each hanger rack (140), the curved configuration maintains consistent spacing and alignment between individual hangers, preventing the tangling and disorganization that typically occurs during conventional collection activities. This uniform orientation and generous capacity can reduce the need for subsequent manual sorting operations that traditionally consume considerable labor time at processing facilities.

[0100] Following completion of hanger collection activities, as shown in FIG. 5G, service technicians and / or end users can secure the accumulated hangers by engaging hanger locks (150) associated with each hanger rack (140). Each hanger lock (150) can transition from an unlocked configuration to a locked configuration by pivoting relative to frame (102) to engage with hangers positioned on hanger racks (140). In some instances, one hanger lock (150) may be transitioned to the locked configuration while others remain in the unlocked configuration to receive additional hangers. This selective locking capability enables service technicians or end users to fill and secure one rack while maintaining other racks in a configuration ready to receive more hangers, thereby optimizing the collection process through simultaneous securing and loading operations. The locking process, as illustrated in FIGS. 6A-6B, can involve rotating hanger locks (150) to compress hangers (2) against hanger racks (140) and deformable body (180), creating frictional forces that inhibit hanger movement during subsequent transportation activities. This securing mechanism maintains the uniform orientation established during collection while preventing hangers from shifting, sliding, or becoming disorganized during transport between customer locations and service vehicles.

[0101] During a subsequent delivery cycle, when sendee technicians return to customer locations to deliver new uniforms and pick up soiled garments, they may collect portable hanger rack assembly (100) once it has been filled with used hangers. The service technician may then leave anew, empty portable hanger rack assembly (100) at the customer's location for continued hanger collection.

[0102] With hangers securely locked in position, service technicians can ergonomically transport portable hanger rack assembly (100) intended for removal, along with supported hangers, from customer facilities to service trucks. As illustrated in FIG. 5H, portable hanger rack assembly (100) can be tilted onto wheels (114) to enable rolling transport across various surface types encountered in customer environments. The balanced design distributes weight effectively between wheels (114) and the supportstructure, allowing technicians to maneuver fully -loaded portable hanger rack assembly (100) with minimal physical effort. The ergonomic transport capability reduces the physical strain associated with lifting and carrying large quantities of hangers while maintaining organizational integrity throughout the movement process.

[0103] During removal from customer facilities, wheels (114) facilitate smooth navigation through doorways, corridors, and loading areas commonly encountered in commercial service environments. The angled configuration of legs (112) positions wheels (114) to minimize interference with stairs and elevated surfaces, enabling technicians to efficiently move portable hanger rack assembly (100) between different elevation levels without excessive lifting or awkward maneuvering. The stable support provided by kickstand (130) and legs (112) maintains portable hanger rack assembly (100) in proper orientation during transport activities, preventing tipping or instability that could compromise hanger organization or create safety hazards for sendee personnel.

[0104] The portable hanger rack assembly assemblies described herein can incorporate various design modifications and configurations to accommodate different operational requirements and manufacturing considerations. For example, in some instances, locking mechanisms (e.g., hanger lock (150)) may include additional or alternative features that inhibit such locking mechanism from inadvertently transitioning out of the locked configuration during illustrative use in accordance with the description herein.

[0105] As another example, some portable hanger rack assembly configurations can eliminate collapsible features while incorporating alternative space-saving approaches that address storage and transportation constraints. Non-collapsible designs can utilize fixed frame configurations that achieve space efficiency through different means. For example, multiple portable hanger rack assemblies can be stored in a nested configuration to save space during transportation and storage while not in use. Nesting arrangements enable multiple assemblies to be positioned within each other or in overlapping configurations that minimize the combined spatial footprint whenassemblies are not actively supporting hangers. Nested configurations can incorporate complementary dimensional relationships between different assemblies that enable efficient stacking or interlocking arrangements during storage periods.

[0106] FIGS. 7A-7B show an illustrative alternative portable hanger rack assembly (200) in accordance with the present disclosure. Portable hanger rack assembly (200) achieves many of the same functional features as portable hanger rack assembly (100), including mobility while supporting post-use hangers, the ability to save space in a delivery truck or storage area while not in use, the ability to receive post-use hangers at a predetermined orientation, and the ability to lock post-use hangers against its rack for secure transportation. However, as will be described in greater detail below, portable hanger rack assembly (200) differs in its space-saving approach by utilizing a nesting configuration that allows multiple racks to be efficiently stored within each other when not in use, rather than relying on a folding mechanism. Additionally, portable hanger rack assembly (200) employs a latching mechanism to maintain the locked configuration of the locking mechanism, using positive mechanical engagement through latching locks (260) rather than solely relying on a frictional braking force employed by portable hanger rack assembly (100).

[0107] Portable hanger rack assembly (200) includes a frame (202), wheels (214). a plurality of hanger racks (240), and a respective hanger lock (250) associated with each respective hanger rack (240). Frame (202) provides structural support and mounting locations for hanger collection components. Frame (202) includes a base (204) positioned at a lower portion of portable hanger rack assembly (200) to establish ground contact and stability during hanger collection operations at customer facilities. Base (204) engages with floor surfaces to maintain portable hanger rack assembly (200) in a stable upright position while service technicians and users interact with hanger collection components. Frame (202) further includes vertical bars (206) that extend upward from an axle (216) supporting wheels (214). Vertical bars (206) are shown to be connected to base (204) via hanger lock rails (205) to create primary structuralelements that support various operational components of portable hanger rack assembly (200). A handlebar (208) connects to vertical bars (206) at an upper portion of frame (202) to provide a gripping location that enables service technicians to maneuver portable hanger rack assembly (200) during transportation activities between customer locations and service vehicles.

[0108] Hanger lock rails (205) are shown to be coupled with vertical bars (206) adjacent to handlebar (208) and to taper laterally inward (e.g.. toward the opposite hanger lock rail (205)) as they extend downwardly away from vertical bars (206). Additionally, base (204) is shown to have a lateral dimension that is smaller than the lateral window defined by the two vertical bars (206) at the corresponding height. Therefore, hanger lock rails (205) and base (204) of a first portable hanger rack assembly (200) are dimensioned to fit within the window defined by vertical bars (206) and handlebar (208) of a second portable hanger rack assembly (200) when each portable hanger rack assembly (200) does not support hangers in accordance with the description herein. This allows for a nesting configuration of multiple portable hanger rack assemblies (200) when they are not being used to receive and / or transport hangers in accordance with the description herein.

[0109] Portable hanger rack assembly (200) achieves space-saving benefits through this nesting configuration that allows multiple assemblies to be efficiently stored within each other when not actively supporting hangers. This nesting approach addresses storage and transportation constraints encountered in service vehicle cargo areas and processing facility storage locations. Multiple portable hanger rack assemblies (200) can be positioned in overlapping arrangements that minimize combined spatial footprints during periods when assemblies are not loaded with hangers. The nesting capability enables service technicians to transport multiple assemblies to customer locations without consuming excessive vehicle space, while also facilitating efficient storage at processing facilities when assemblies are not in active use.

[0110] With continued reference to FIGS. 7A-7B, portable hanger rack assembly (200) includes multiple hanger racks (240) mounted between hanger lock rails (205) to provide hanger receiving and organizing capabilities. Hanger racks (240) can be substantially similar to hanger racks (140) described above, with certain differences elaborated herein. Therefore, each hanger rack (240) extends horizontally to create receiving areas that accommodate post-use hangers during collection processes at customer facilities. Hanger racks (240) position hangers in consistent orientations to eliminate the random positioning that typically occurs during conventional hanger collection activities, thereby reducing subsequent manual sorting operations at processing facilities. The horizontal extension of hanger racks (240) from hanger lock rails (205) creates accessible receiving areas that enable users to easily place hangers among other individual hangers positioned on each hanger rack (240).

[0111] Referring to FIG. 8, each hanger rack (240) includes a hook receiving wall (242) and a neck receiving wall (244) that together create a J-shaped configuration similar to that of hanger racks (140) described above. Hook receiving wall (242) provides a curved support surface that accommodates hanger hooks while neck receiving wall (244) extends from hook receiving wall (242) to guide proper hanger placement and discourage incorrect orientation during collection activities. The J-shaped geometry establishes a receiving channel that naturally guides hangers into consistent positioning arrangements when placed on portable hanger rack assembly (200), making correct placement significantly easier than incorrect placement through intuitive physical design. Neck receiving wall (244) is shown to connect to hanger lock rails (205) through respective couplings (245).

[0112] While not shown in the figures, a deformable body may be attached to neck receiving wall (244). Such a deformable body may be substantially similar to deformable body (180) described above. The deformable body may be positioned along neck receiving wall (244) to provide cushioned contact with hangers when hanger lock (250) engages hangers positioned on hanger rack (240).

[0113] The deformable body may extend along a portion of neck receiving wall (244) that is intended to contact and support hangers during use. This placement may ensure that the deformable body contacts hangers when they are positioned on hanger rack (240) and secured by hanger lock (250). In some instances, the deformable body may be configured for removable attachment to neck receiving wall (244), facilitating replacement when wear occurs over time. Various coupling mechanisms may be employed to secure the deformable body to neck receiving wall (244), including adhesive bonding, mechanical fastening systems, or resilient clip structures that engage with corresponding features on the neck receiving wall. It will be appreciated that a deformable body may additionally or alternatively be incorporated into or associated with other portions of a hanger rack (240) and / or a hanger lock (250).

[0114] The deformable body may conform to variations in hanger dimensions and geometries while promoting consistent securing pressure across different hanger types. The elastically deformable material may absorb movement and provide cushioned contact between hanger lock (250) and hangers, contributing to vibration dampening during transportation activities. This cushioned interface may accommodate repeated compression cycles while maintaining securing effectiveness over extended operational periods, similar to the functionality provided by deformable body (180) in portable hanger rack assembly (100).

[0115] Each hanger rack (240) is shown to connect to hanger lock rails (205) through rail mounts (246) associated with the respective couplings (245). The rail mounts (246) can provide a secure attachment point, while potentially enabling controlled movement along hanger lock rails (205). For example, in one embodiment, hanger racks (240) can be secured to hanger lock rails (205) at fixed positions. However, in some instances, hanger racks (240) may be adjustable in position along the length of hanger lock rails (205), allowing for customization of the spacing between multiple hanger racks (240) of a portable hanger rack assembly (200). Rail mounts (246) may include any suitable structure as would be apparent to one skilled in the art in view of the teachings herein,including but not limited to clamps, brackets, sliding mechanisms, or other attachment configurations that facilitate secure mounting while potentially allowing for positional adjustment.

[0116] The couplings (245) of hanger rack (240) can together include a pair of side walls (248) that hook receiving wall (242) and neck receiving wall (244) extend between. Side walls (248) in the current example are shown to be substantially fixed relative to hook receiving wall (242) and neck receiving wall (244). Each side wall (248) defines a latch recess (247). As will be described in greater detail below, latch recesses (247) can be configured to accommodate locking mechanisms (e.g., latching lock (260)) in order to secure post-use hangers (2) supported on hanger rack (240).

[0117] As further shown in FIG. 8. portable hanger rack assembly (200) can incorporate at least one hanger lock (250) associated with each hanger rack (240) to provide securing capabilities that prevent hanger movement during transportation between customer locations and service vehicles. In particular, hanger lock (250) is shown to include a pivoting body (252) that transitions between locked and unlocked configurations through rotational movement relative to hanger rack (240) and frame (202). Pivoting body (252) incorporates a hanger engagement surface (254) positioned to contact and secure hangers when hanger lock (250) transitions from an unlocked configuration (see FIG. 7A) into a locked configuration (see FIG. 7B). Hanger engagement surface (254) extends across portions of hanger rack (240) that support hangers, enabling comprehensive engagement with multiple hangers simultaneously when locking mechanisms are activated.

[0118] Hanger engagement surface (254) may include multiple contact points configured to drive hangers against hook receiving wall (242) and neck receiving wall (244). These multiple contact points may be similar to first hanger contact surface (1 8) and second hanger contact surface (178) described above in relation to portable hanger rack assembly (100). The multiple contact points may be positioned at different locations along hanger engagement surface (254) to engage different portions of hangers w henhanger lock (250) is in the locked configuration. In some instances, these multiple contact points may be formed from different components that are assembled together to create a unified engagement surface with varied contact geometries. Alternatively, as in the example of FIG. 8, the multiple contact points may be formed from the same component through strategic contouring or profiling of a single structural element.

[0119] In some instances, the multiple contact points may incorporate different materials or surface treatments to optimize their interaction with hangers. For example, certain contact points may include deformable materials similar to deformable body (180) described above, which may compress when engaging hangers to create secure connections while absorbing vibrations during transportation. The multiple contact points may work in coordination to maintain consistent hanger orientation and prevent movement during transport activities between customer locations and service vehicles.

[0120] Pivoting body (252) can connect to hanger rack (240) through a pivot coupling (255) that enables controlled rotational movement between the unlocked configuration (see FIG. 7A) and the locked configuration (see FIG. 7B) while maintaining structural integrity during repeated operational cycles. Pivot coupling (255) provides a hinged connection that allows pivoting body (252) to rotate relative to hanger rack (240) while preventing excessive movement that could compromise locking effectiveness or component alignment. The pivotal connection enables hanger lock (250) to transition smoothly between configurations while maintaining proper positioning relative to hangers supported on hanger rack (240).

[0121] Referring to FIG. 9, each end of pivoting body (252) can incorporate a respective latch housing (256) that defines a hollow interior (253) dimensioned to slidably accommodate a respective latching mechanism (e.g.. latching lock (260)) used to selectively maintain hanger lock (250) in a locked configuration, which may be useful during transportation activities in accordance with the description herein. Latch housing (256) further defines a rod opening (257), a handle opening (258), and latch body opening (259) (see FIG. 8) that are in communication with hollow interior (253).Rod opening (257) in the current example slidably houses a portion of a guide rod (266) of a respective latching lock (260), thereby guiding latching lock (260) along a predetermined path relative to pivoting body (252) between a latched position (see FIG.10A) and an unlatched position (see FIG. 10B).

[0122] Handle opening (258) provides user access for a handle (262) of a respective latching lock (260) while also allowing handle (262) to slide relative to pivoting body (252) in accordance with the description herein. As at least shown in FIGS. 8 and 10A-10B, latch body opening (259) extends through latch housing (256) to accommodate latching components (e.g., latch body (264)) that engage with latch recess (247) of rail mount (246) to selectively secure hanger lock (250) in the locked position. The multiple openings within latch housing (256) slidably accommodate a respective latching lock (260) while providing user access, guided movement, and alignment during latching and unlatching operations.

[0123] Latch housing (256) accommodates latching lock (260) to provide positive mechanical engagement to maintain hanger lock (250) in locked configurations rather than relying on merely frictional braking forces. Latching lock (260) thus engages with latch recess (247) defined by a respective side wall (248) of hanger rack (240) to create mechanical connections that resist inadvertent movement of hanger lock (250) from locked positions during transportation activities. The positive mechanical engagement provided by latching locks (260) differs from the frictional braking approach used in portable hanger rack assembly (100), where locking surfaces (156, 166) create resistance through surface contact and friction forces.

[0124] Latching locks (260) in the current example each incorporate handle (262), latch body (264), guide rod (266). and a biasing feature in the form of bias spring (268). Guide rod (266) extends through rod opening (257) to provide guided movement and alignment during latching operations, such as movement of latching lock (260) between the latched position (see FIG. 10A) and the unlatched position (see FIG. 10B). The block portion of latching lock (260) that is slidably contained within hollow interior (253)may also be used to provide guided movement and alignment during latching operations. In some instances, either the guide rod (266) or the block portion alone may be sufficient to provide the necessary guidance and alignment, depending on the specific design requirements and manufacturing considerations.

[0125] Bias spring (268) can be interposed between a portion of latching lock (260) housed within hollow interior (253) and the portion of latch housing (256) defining hollow interior (253). The bias spring (268) may be positioned to contact an internal surface of latch housing (256) at one end while engaging with a corresponding surface of the latching lock (260) component at the other end. This arrangement creates a spring- loaded mechanism that continuously applies force to urge latching lock (260) toward the latched position shown in FIG. 10A.

[0126] Bias spring (268) may be configured as a compression spring that becomes compressed when latching lock (260) is moved away from the latched position, thereby storing potential energy that encourages return to the latched configuration. In some embodiments, bias spring (268) may be positioned around guide rod (266) or adjacent to other components of latching lock (260) within hollow interior (253). The spring force provided by bias spring (268) may be calibrated to provide sufficient biasing force to maintain latching lock (260) in the latched position during normal operational conditions while still allowing manual override when a user applies appropriate force to handle (262). The biasing action of bias spring (268) helps ensure that latching lock (260) naturally returns to and remains in the latched position, providing consistent securing of hanger lock (250) without requiring continuous user input. It will be appreciated that, in other embodiments, a bias spring can alternatively comprise a different type or arrangement of spring, or no bias spring or element may be provided.

[0127] With continued reference to FIG. 9, latching locks (260) incorporate a handle (262) that enables manual operation of locking mechanisms by service technicians and users during hanger collection and transportation activities. Handle (262) is slidably disposed within handle opening (258) defined by its respective latch housing (256).Handle (262) provides a gripping surface that allows users to actuate a respective latching lock (260) between the latched and unlatched positions to control the locked and unlocked configurations of hanger lock (250).

[0128] A latch body (264) connects to handle (262) and extends through latch body opening (259) to engage with latch recess (247) when latching locks (260) are activated. Latch body (264) includes a cam surface on one end that allows latch body (264) to cam against portions of side wall (248) defining latch recess (247) as pivoting body (252) is pivoted from the unlocked configuration (see FIG. 7A) into the locked configuration (see FIG. 7B). The bias spring (268) continuously biases latching lock (260) toward the latched position, and the cam surface engagement temporarily overcomes this bias force to allow latch body (264) to reach the inside of latch recess (247). Once positioned within latch recess (247), bias spring (268) actuates latch body (264) into suitably confinement within latch recess (247). Latch body (264) presents a stop surface that engages with latch recess (247) when pivoting body (252) is in the locked configuration, thereby inhibiting inadvertent movement of hanger lock (250) out of the locked configuration. This positive mechanical engagement can ensure hangers remain securely locked during transport even when subjected to vibration or movement. In one embodiment, as shown in FIG. 9, latch body (264) can be tapered to facilitate its selfmovement from an extended position to a retracted position upon contact thereof with side wall (248) when the hanger lock (250) is closed, versus requiring a user to manually move the latch body (264) through use of the handle (262) to facilitate closure of the hanger lock (250). While each end of the hanger lock (250) is shown to comprise a respective latching lock (260), it will be appreciated that, in certain alternative embodiments, a latching lock might only be provided at a single end of a hanger lock, or not at all.

[0129] Referring to FIGS. 7A-7B, the operation of hanger lock (250) can involve coordinated movement between pivoting body (252) and latching locks (260) to achieve secure engagement with hangers positioned on hanger rack (240). When hanger lock (250) isinitially in the unlocked configuration shown in FIG. 7A, pivoting body (252) is positioned away from hanger rack (240), allowing hangers to be freely placed on or removed from the rack.

[0130] To transition hanger lock (250) from the unlocked configuration to the locked configuration, a user applies rotational force to pivoting body (252) about pivot coupling (255). As pivoting body (252) rotates toward hanger rack (240), hanger engagement surface (254) begins to approach and eventually contact hangers positioned on the rack. During this rotational movement, latch body (264) of each latching lock (260) approaches its corresponding latch recess (247) defined by side wall (248).

[0131] As pivoting body (252) continues its rotation toward the locked position shown in FIG.7B, the cam surface of latch body (264) contacts the edge of latch recess (247). This contact creates a camming action that temporarily pushes latch body (264) inward against the bias force of bias spring (268), allowing latch body (264) to slide past the edge of latch recess (247). The cam surface, which in this example is shown to be chamfered, facilitates smooth entry of latch body (264) into latch recess (247) without requiring precise alignment or excessive force from the user.

[0132] Once latch body (264) clears the edge of latch recess (247) and enters the latch recess (247), bias spring (268) automatically urges latching lock (260) back toward the latched position shown in FIG. 10A. This spring-loaded action causes latch body (264) to extend into latch recess (247), where the stop surface of latch body (264) can engage with one or more of the walls of the latch recess (247) to prevent inadvertent withdrawal. The automatic engagement of latching locks (260) can occur without additional user input, as the spring bias can ensure that latch body (264) naturally seeks and maintains the latched position once properly positioned within latch recess (247).

[0133] When hanger lock (250) reaches the fully locked configuration shown in FIG. 7B, pivoting body (252) compresses hangers against hanger rack (240) through hanger engagement surface (254), while latching locks (260) maintain the locked positionthrough positive mechanical engagement between latch body (264) and latch recess (247). This dual-action securing mechanism provides both hanger retention through compression and lock position maintenance through mechanical engagement, ensuring that hangers remain securely positioned during transportation activities even when subjected to vibration or movement.

[0134] When a user wishes to transition hanger lock (250) from the locked configuration to the unlocked configuration, they can easily do so through a simple two-step process. First, the user can firmly grasp the ergonomically designed handle (262) of each latching lock (260), and apply gentle lateral pressure to slide the latching locks (260) from their secure latched positions (e.g., shown in FIG. 10A) to the disengaged unlatched positions (e g., illustrated in FIG. 10B). This sliding motion compresses bias spring (268), temporarily overcoming its resistance. Once latching locks (260) are maintained in the unlatched configuration, the user may then apply rotational force to smoothly pivot the entire assembly away from the hanger rack (240), transitioning from the locked configuration to the fully accessible unlocked configuration depicted in FIG.10C. This deliberate two-stage unlocking mechanism prevents accidental release while still allowing authorized users to quickly access the secured hangers when needed.

[0135] It should be understood that latching locks (260) may incorporate alternative and / or additional suitable structures as would be apparent to one skilled in the art in view' of the teachings herein to achieve the desired latching effect. For example, latching locks may incorporate cam mechanisms, ratcheting components, magnetic latches, detent assemblies, friction -based locking elements, spring-loaded pins, sliding collars, rotary locks, lever-actuated mechanisms, or any other suitable mechanical or electromechanical latching structures.

[0136] It should be understood that elements of portable hanger rack assembly (200) can be incorporated into portable hanger rack assembly (100) to provide alternative operational characteristics. For example, hanger lock rails (205) and associated latching mechanisms from portable hanger rack assembly (200) can be integrated into portablehanger rack assembly (100) to provide positive mechanical engagement for locking operations. Similarly, nesting features from portable hanger rack assembly (200) can be incorporated into portable hanger rack assembly (100) to provide additional spacesaving options beyond collapsible configurations. Portable hanger rack assembly (200) can be used as a replacement for portable hanger rack assembly (100) in applications where nesting capabilities are preferred over collapsible features, or where positive mechanical latching is desired over frictional braking approaches for maintaining locked configurations during transportation activities.

[0137] While portable hanger rack assemblies (100, 200) described above incorporate hanger racks (140, 240) that extend horizontally from frame structures, some portable hanger rack assembly configurations can utilize vertical arrangements that provide alternative organizational approaches for hanger collection and storage activities. In vertical configurations, hanger racks can extend upward from base structures or frame components to create receiving areas that accommodate hangers in stacked arrangements. Vertical hanger rack arrangements can facilitate user interaction patterns that differ from horizontal configurations. Users can access vertically arranged hanger racks through upward or downward placement motions rather than lateral insertion movements. Vertical configurations can also enable gravity-assisted hanger positioning, where hangers naturally settle into receiving areas through downward movement rather than requiring precise lateral alignment during placement operations.

[0138] Some vertical hanger rack configurations can incorporate guide structures or alignment features that direct hangers into proper orientations during vertical placement activities. Such guide structures can include funnel-shaped receiving areas, tapered entry points, or graduated spacing arrangements that accommodate hangers of varying sizes while maintaining consistent organizational patterns. Vertical arrangements can also utilize different securing mechanisms compared to horizontal configurations, potentially incorporating top-down compression systems, lateral containment features, or gravity-assisted retention methods that maintain hanger positions during transportation activities.

[0139] FIGS. 11-12 show an illustrative alternative portable hanger rack assembly (300) that may be utilized in replacement for portable hanger rack assemblies (100, 200) described above. Portable hanger rack assembly (300) includes a frame (302), wheels (314), a hanger orientation alignment column (340), a hanger lock (350), and a hanger sheath (370). As will be described in greater detail below, portable hanger rack assembly (300) is configured to be mobile and transportable similar to portable hanger rack assemblies (100, 200) described above. As will also be described in greater detail below, frame (302) and a hanger rack in the form of hanger orientation alignment column (340) are configured to receive a vertical stack of hangers, while hanger lock (350) is configured to inhibit stacked hangers from disassociating with hanger orientation alignment column (340) during transport and handling.

[0140] Referring to FIG. 12, the frame (302) can provide structural support for vertical hanger collection and organization activities. Frame (302) includes a base (304) positioned at a lower portion of portable hanger rack assembly (300). Base (304) includes a floor (303) and a peripheral wall (305) that together define a partially enclosed receiving area configured to accommodate hangers in a vertical stacking arrangement. This enclosed receiving area can be dimensioned to complement the profile of hangers (2), where the geometric configuration of the enclosed receiving area works in concert with the natural contours of hangers (2). The complementary dimension of the enclosed receiving area as compared to hangers (2) ensures that hooks (4) and necks (6) of stacked hangers (2) align relative to each other.

[0141] Vertical bars (306) extend upward from base (304) to create primary structural elements that support operational components of portable hanger rack assembly (300). As shown in FIGS. 11-12, vertical bars (306) can be configured to receive an interior portion of hangers (2) defined by arms (8). The vertical bars (306) can be spaced apart at a distance that accommodates the width of standard hangers (2), allowing hangers tosurround or at least partially surround vertical bars (306). The height of vertical bars (306) is sufficient to accommodate multiple hangers (2) stacked vertically, with each hanger's arms (8) guided by the parallel configuration of the vertical bars (306) to prevent tangling or disorganization during transport and / or collection.

[0142] A handlebar (308) connects to vertical bars (306) at an upper portion of frame (302) to provide a gripping location that enables service technicians to maneuver portable hanger rack assembly (300) during transportation activities between customer locations and service vehicles. Frame (302) is shown to further include a cross bar (310) that extends between vertical bars (306) to provide additional structural rigidity and mounting locations for hanger collection components.

[0143] Portable hanger rack assembly (300) incorporates wheels (314) mounted to base (304) to facilitate transportation across various surface ty pes encountered in commercial service environments. Wheels (314) enable service technicians to easily move portable hanger rack assembly (300) when supporting substantial loads of hangers, distributing weight effectively to allow maneuvering with minimal physical effort while maintaining secure orientation of hangers during transport.

[0144] Portable hanger rack assembly (300) is also shown to include a hanger orientation alignment column (340) that extends in a vertical direction from base (304) to create a receiving structure that accommodates hangers in stacked arrangements. Hanger orientation alignment column (340) differs from horizontal hanger racks (140, 240) described above by providing vertical receiving capabilities that enable hangers to be positioned through downward placement motions rather than lateral insertion movements. Hanger orientation alignment column (340) facilitates user interaction patterns that utilize gravity-assisted hanger positioning, where hangers naturally settle into receiving areas through downward movement rather than requiring precise lateral alignment during placement operations.

[0145] Hanger orientation alignment column (340) can include a hook receiving wall (342) and an inward projection (344), as at least shown in FIG. 13. Hook receiving wall (342)provides a surface against which hooks (4) of hangers (2) can abut when inserted into portable hanger rack assembly (300). Inward projection (344) extends at an angle from hook receiving wall (342), so as to assist in defining a channel receiving area for naturally guiding hangers into proper alignment. The channel receiving area, defined at least in part through geometric relationship between hook receiving wall (342) and inward projection (344), can accommodate variations in hanger dimensions while ensuring consistent orientation of hangers. The surfaces of hook receiving wall (342) and inward projection (344) can thus cooperatively provide structural guidance and positioning features that facilitate proper hanger alignment during vertical placement activities, effectively eliminating the random positioning that might otherwise occur during conventional hanger collection. It will be appreciated that hanger orientation alignment column (340) may have any suitable vertical dimension, or any of a variety of suitable alternative design characteristics, as would be apparent to one skilled in the art in view of the teachings herein.

[0146] Hanger lock (350) associates with frame (302) to selectively provide securing capabilities that prevent hanger movement during transportation between customer locations and service vehicles. In the current example, hanger lock (350) is shown to include a panel (352), a rotating knob (360), and a vertical post (362). Vertical post (362) is shown to extend upward from base (340), within the channel receiving area defined at least partially by hook receiving wall (342) and inward projection (344). Rotating knob (360) can be positioned at, and attached to, an upper end of vertical post (362), such that rotating knob (360) is located above the intended stack of hangers (2) at maximum capacity.

[0147] Rotating knob (360) is configured to rotate relative to frame (302) between an unlocked position (see FIG. 14) and a locked position (see FIG. 15). As will be described in greater detail below; in the unlocked position, rotating knob (360) can be dimensioned to fit within an opening (354) defined by panel (352), thereby allowing panel (352) freedom to be pivoted between an open position (see FIG. 14) and a closed position(see FIG. 15). However, in the locked position with panel (352) in the closed position as shown in FIG. 15, rotating knob (360) can be dimensioned to inhibit panel (352) from inadvertently pivoting out of the closed position, thereby retaining the stack of hangers (2) during transportation.

[0148] Again, panel (352) can be pivotally coupled to frame (302) such that panel (352) may move between an open position (see FIG. 14) and a closed position (see FIG. 15). When in the open position, panel (352) allows stacking of hangers in accordance with the description herein. In the closed position, panel (352) inhibits further such stacking of hangers. Panel (352) defines an opening (354) configured to accommodate knob (360) and a portion of post (362) during locking and unlocking activities. When panel (352) is in the closed position and knob (360) is rotated into the locked position, knob (360) inhibits panel (352) from pivoting out of the closed position. With panel (352) in the closed position, panel (352) inhibits stacked hangers (2) from disassociating from portable hanger rack assembly (300) by creating a physical barrier that prevents upward movement of the stacked hangers. This dual-action securing mechanism ensures hangers remain properly contained during transport and handling operations.

[0149] Panel (352) is shown to include snap-fit features (356) that enable hanger lock (350) to selectively engage with corresponding structures of frame (302). For example, snap- fit features (356) can facilitate selective retention of panel (352) in an opened position (see FIG. 12) during loading of hangers. A similar snap-fit feature is shown to facilitate pivotal coupling of panel (352) to cross bar (310). It will be appreciated, however, that any of a variety of other suitable arrangements can be provided to facilitate coupling of a panel to a frame and / or to selectively retain the panel in an open position. For example, a panel may be pivotally or otherwise movably attached to a frame via any suitable means as would be apparent to one skilled in the art in view of the teachings herein. Such alternative attachment mechanisms may include, but are not limited to, hinges, pins, living hinges, ball-and-socket joints, or other rotational coupling arrangements that allow panel to swing smoothly or otherwise move between positions,while optimally (though not necessarily) maintaining alignment with opening (354) relative to knob (360) and post (362), ensuring reliable operation of the locking mechanism throughout repeated use cycles.

[0150] As will be appreciated from FIGS. 12-13, hanger sheath (370) can be configured to act as a sheath for hangers (2) accumulating on portable hanger rack assembly (300). A bottom end of sheath (370) can selectively mate with base (304) to thereby allow hanger sheath (370) to selectively couple with other components of portable hanger rack assembly (300). Hanger sheath (370) includes a body (372) that extends upwardly from base (304) when coupled thereto. Body (372) is dimensioned to surround a stack of hangers (2) positioned on portable hanger rack assembly (300), thereby maintaining the hangers (2) in a consistent orientation during transport. Body (372) may be constructed from a durable, lightweight material such as plastic, metal, or composite materials that provides sufficient rigidity to contain hangers (2) while remaining lightweight enough for easy handling.

[0151] In one embodiment, hanger sheath (370) can define a window (374) that allows users to visually determine the quantity of hangers (2) and available storage space within portable hanger rack assembly (300). Window (374) may extend along a portion of the vertical length of body (372), allowing users to monitor hanger capacity without needing to open or remove hanger sheath (370). This visual monitoring capability enables service technicians to efficiently determine when portable hanger rack assembly (300) has reached capacity and requires empty ing or replacement.

[0152] Portable hanger rack assembly (300) may be utilized in commercial laundry’ and uniform service operations to facilitate efficient vertical hanger collection and transportation processes. Service technicians can utilize portable hanger rack assembly (300) to streamline collection workflows while maintaining proper hanger orientation throughout the entire process from customer facilities to processing centers through its vertical stacking approach.

[0153] During initial setup at customer locations, portable hanger rack assembly (300) can be positioned with panel (352) in the open position as shown in FIG. 13. In this configuration, the open panel (352) allows unobstructed access to the channel receiving area defined at least partially by hook receiving wall (342) and inward proj ection (344), enabling users to easily insert hangers (2) on top of floor (303) of base (304) for vertical stacking. The open position of panel (352) allows for efficient loading operations while hanger orientation alignment column (340) guides proper hanger placement.

[0154] As hangers (2) are inserted into portable hanger rack assembly (300), the geometric relationship between hook receiving wall (342) and inward projection (344) naturally guides each hanger into a predetermined orientation. The complementary surfaces work cooperatively to ensure that hooks (4) and necks (6) of successive hangers (2) align consistently relative to each other as they are stacked vertically . This alignment process occurs through gravity-assisted positioning, where each hanger naturally settles into the channel receiving area with minimal user intervention, effectively eliminating the random positioning that often characterizes conventional hanger collection activities.

[0155] The vertical bars (306) further contribute to maintaining predetermined hanger orientation by receiving the interior portions defined by arms (8) of each hanger (2). As hangers are stacked, their arms (8) are guided by the parallel configuration of vertical bars (306), which prevents tangling or disorganization during the stacking process. This guidance system ensures that each successive hanger maintains the same spatial relationship to the previous hangers in the stack, creating a uniform and organized collection.

[0156] Throughout the loading process, service technicians and users can monitor the accumulation of hangers through window (374) defined in hanger sheath (370). Window (374) provides visual access to the interior of portable hanger rack assembly (300), allowing users to observe the growing stack of hangers (2) without needing to remove or reposition any components. This visual monitoring capability’ enablesefficient capacity management, as users can readily determine when portable hanger rack assembly (300) is approaching its maximum capacity and requires attention.

[0157] The transparency provided by window (374) also allows users to verify that hangers are maintaining their proper orientation during the stacking process. Senice technicians can observe through window (374) to confirm that hooks (4) and necks (6) remain aligned and that arms (8) are properly positioned relative to vertical bars (306). This visual feedback helps ensure that the predetermined orientation is maintained throughout the collection process.

[0158] Once portable hanger rack assembly (300) has been filled to the desired capacity, as can be determined through observation via window (374), users can secure the accumulated hangers for transportation. Panel (352) may be pivoted from the open position shown in FIG. 12 to the closed position shown in FIG. 15. This pivotal movement positions panel (352) above the stack of hangers (2), creating a physical barrier that prevents upward movement of the stacked hangers.

[0159] With panel (352) in the closed position, rotating knob (360) may be rotated from the unlocked position to the locked position. In the locked position, rotating knob (360) is dimensioned to inhibit panel (352) from inadvertently pivoting upward out of the closed position, as shown in FIG. 15. This dual-action securing mechanism ensures that the stack of hangers (2) remains properly contained and secured within portable hanger rack assembly (300) during subsequent handling and transportation activities and provides a user or technician with quick visible indication of the same.

[0160] The locking action of rotating knob (360) provides positive retention of panel (352) in the closed position, preventing accidental opening that could result in hanger displacement or loss during transport. This securing capability is particularly beneficial when portable hanger rack assembly (300) is subjected to movement, vibration, or tilting during transportation between customer locations and service vehicles.

[0161] Following the securing of hangers through the closed and locked configuration of panel (352) and rotating knob (360), service technicians can transport portable hanger rack assembly (300) to suitable locations. The user may tilt portable hanger rack assembly (300) onto wheels (314) to enable rolling transport across various surface types encountered in customer environments.
