Description

Technical Field

[0001] This disclosure relates to a portable device, and more specifically to a chair or multi-functional grooming chair that is easy to assemble, disassemble, and carry for providing seating for service recipients. Background Technology

[0002] Existing technologies are referenced in this section.

[0003] Therefore, grooming service providers typically equip their premises with specialized adjustable grooming chairs designed to meet their needs. However, grooming service providers offering services far from their premises (such as homes or offices) may not be able to use specialized chairs: such chairs are unlikely to be available in grooming establishments, and it is impossible to move chairs from their professional locations as they are usually permanent fixtures and are large and bulky (e.g., a typical barber chair can weigh 60-70 kg). In this case, the service provider will need to use available items in the grooming establishment, such as kitchen stools, office chairs, or dining chairs. However, this can pose problems for grooming service providers, not only due to the inconvenience caused by not being able to properly position their clients, but also affecting their physical health. For example, a grooming service provider may handle multiple different clients in different locations within a few hours, and if the client's improper positioning forces the provider to stretch or bend over, they may suffer physical strain as a result. [US Patent Application Publication US20230346123A1, entitled "Assemblage for forming a treatment chair"]

[0004] "In barber chairs and similar grooming chairs, grooming tools should be kept within easy reach (e.g., in a tool rack) while the customer or occupant is receiving a grooming service. Due to hygiene regulations and other reasons, it is desirable to keep tools sterile. For example, in a barber chair, if scissors and combs are within the barber's reach and placed in a support rack that automatically sterilizes between uses, the barber does not have to walk to an adjacent counter or equipment where tools are stored, saving considerable time and effort. It is also very useful that the barber can easily put down and pick up tools for brief use. Until now, it has been difficult to provide a convenient tool support rack that does not hinder the barber's movement, restrict their movement around the chair, or impede the chair's rotation. With the development of structures that allow power to be brought to the top of the chair, which can rotate and be raised, it has become possible to carry electric equipment (such as scissors) with the chair." [US Patent Application Publication US3235305A, entitled "Barber chair with sterilizer"]

[0005] "Due to the increasing number of elderly women living at home and working women, the demand for in-home beauty services is increasing. The number of elderly women disabled due to arthritis and other reasons is also rising, as is the number undergoing rehabilitation. Furthermore, due to increased life expectancy, more and more elderly women are becoming frail. These women are prone to depression and boredom, highlighting the need for in-home beauty services to 'boost their spirits.'" [US Patent Application Publication US5489140A, titled "Portable beautician's chair"]

[0006] "While many conventional reclining chairs function well, equipment manufacturers continue to develop improved frames and actuation mechanisms to reduce system complexity, enhance operational smoothness, and improve user comfort. Furthermore, there is a ongoing expectation to develop improved manufacturing and assembly technologies, which will lead to increased efficiency and improved product quality while reducing costs." [US Patent Publication US6655732B1, titled "Multiple position leg rest mechanism for a reclining chair"]

[0007] Therefore, there is a need for a chair that is easy to disassemble, transport from one grooming location to another, and quickly reassemble in situ. Summary of the Invention

[0087] The term "portable device" refers to a device designed for easy transport, movement, and storage. This type of device is typically lightweight, compact, and often features foldable or detachable components for easy carrying and placement in different locations.

[0088] As used in this article, the term "chair" is also referred to as a "multi-purpose grooming chair" or "multi-functional chair," and is a versatile device designed for people undergoing grooming services to sit on, adaptable to a wide range of uses across various industries such as beauty, healthcare, and wellness.

[0089] In this document, the term "treatment" refers to any medical or non-medical grooming applied to a client who must, or preferably, is seated. The portable grooming chair of this invention is preferably used for personal grooming (such as hairdressing / haircuts), but can also be used for cosmetic grooming (such as makeup grooming and tattooing) and for medical grooming (such as dental grooming).

[0090] As used herein, the term "bracket" or "mounting bracket" refers to a hardware component designed to support, mount, or connect two or more parts or structures. Brackets come in various shapes, sizes, and materials depending on their specific application and the type of elements they are intended to join. Brackets are hardware components used to join and support various components in construction and assembly. For example, corner brackets (L-shaped brackets) are L-shaped and are commonly used to connect two components at right angles, and are prevalent in equipment assembly and construction. Flat brackets made of metal or plastic join components in a straight line or provide additional support to a structure. U-shaped brackets (for U-shaped brackets) are used to hold or support cylindrical objects such as pipes and cables. Corner brackets are designed to reinforce corners of structures and are frequently used in shelving units and cabinets.

[0091] As used in this article, the term "modular bracket" refers to a versatile, adjustable component used to support or mount different parts or structures in a customizable manner. Designing these brackets with a modular approach means they can be easily assembled, disassembled, and reconfigured to suit a variety of applications and requirements.

[0092] As used herein, the terms "releasable connection" or "releasable mount" refer to a type of connection between two or more components that allows the components to be securely engaged together but also easily disengaged when needed. This type of connection is designed to be both strong enough to hold the components together during use and simple enough to disengage without significant effort or permanent alteration to the parts involved. Releasable connections in this disclosure can be achieved through various mechanisms, such as clips, latches, latches, magnetic fittings, screws, or other fasteners designed for easy release.

[0093] As used herein, the term "gas spring" (also known as a gas strut, gas lift, or gas shock) refers to a mechanical device that uses compressed gas contained within a cylinder and sealed by a sliding piston to apply force. This force is used to support, lift, or balance weight, providing smooth and controlled movement. Gas springs are commonly used in automotive applications (such as trunk and hood supports), equipment (like adjustable seats and recliners), and a variety of industrial and consumer products. They are also known as hydraulic-pneumatic springs, gas dampers, etc.

[0094] As used herein, the term "hydraulic spring" refers to a mechanical device that uses a combination of spring mechanisms and hydraulic fluid to provide controlled force and motion. This type of device integrates the characteristics of both traditional springs and hydraulic dampers, offering unique advantages in applications requiring precise control of motion, damping, and force application. It is also known as a hydraulic pump, hydraulic height adjustment lever, hydraulic height adjustment mechanism, etc.

[0095] Portable barber chairs are tools that support barbers, providing them with an exceptional experience for their clients. As a luxurious, practical, and intuitive tool, the travel-friendly design is tailored to meet the needs of barbers on the go.

[0096] Figure 1 A perspective view of a chair according to an embodiment is shown. The chair includes a headrest 102, a backrest 104, armrests 106, a seat 108, a footrest 110, a base, and one or more legs 114. The base includes a hydraulic spring 112 configured for height adjustment. The base includes a cover comprising an elastic inner ring, a flexible metal ring, and is configured for magnetic fixation of the cover. It can also be made in a color that is aesthetically appealing to the user. Figure 2A rear view of the chair according to an embodiment is shown. The chair also includes a modular support 220, a footrest / lever 222 for height adjustment, and a power outlet (not visible in the figure, but the wires connected to the power outlet 224 are visible). The assembly includes two sub-assemblies: i) a seat and backrest forming the chair assembly; and ii) a hydraulic spring configured for height adjustment and one or more legs forming the base assembly / support assembly.

[0097] Adjustable foot pedal: Figure 3A An adjustable footrest for a chair according to an embodiment is shown. The footrest 302 is designed to be in three or more different positions: i) a position for a customer to rest their feet; ii) a storage position; and iii) a traveling position. In this embodiment, the footrest is designed to be in more than three positions. The adjustment range 304 is shown in dashed lines, and the adjustment positions are shown as small lines.

[0098] According to an embodiment of the device, the foot pedal can be adjusted to one or more positions using a spring-loaded pin to lock the foot pedal in multiple positions.

[0099] Figure 3B An adjustable footrest with a foot support for a chair according to an embodiment is shown. In the embodiment, the footrest 320 can be releasably mounted to a footrest mounting device 318 on the underside of the seat. The footrest includes an elongated member 322, which is mounted under the seat at the footrest mounting device 318 by means of any adjustable mechanism as described herein. A foot support 324 is attached to the distal end of the elongated member 322, which can be folded between an extended position (for supporting the feet of the person occupying the chair in use) and a folded position (in the embodiment, the foot support rests against the elongated member). The foot support is attached to the distal end of the elongated member by a hinge and preferably includes a stop to limit the maximum relative angle between the foot support and the elongated member in the extended position, for example, to prevent the foot support from unfolding beyond a generally right angle, and the foot support can be releasably mounted so that its use is optional. It can also be provided as an additional accessory with the chair.

[0100] Figure 4An example mechanism for adjusting the footrest of a chair according to an embodiment is shown. The adjustable angle and height of the footrest are secured in multiple positions using a spring-loaded pin mechanism 402. The user presses button 404 to release the locking pin, as shown in step A, and the leg rest rotates freely to the next slot 406, where the pin automatically slides into place. The user can then manipulate the footrest to the desired position, as shown in steps B and C. The spring-loaded automatic locking locks the footrest in the new position, as shown in step D. Button 404 is a press-to-release button, the arrows indicate the direction for manipulating the leg rest (footrest) to the desired position, and step D illustrates the spring-loaded automatic locking.

[0101] In one embodiment, the foot pedal may include and be adjusted using a ratchet mechanism. A foot pedal adjustment mechanism using a ratchet mechanism allows the user to easily adjust and securely position the foot pedal at various angles and / or heights. The mechanism includes a foot pedal, a support arm connecting the foot pedal to a chair or base, a ratchet with a series of teeth, a pawl engaging the ratchet, and a release lever or button to disengage the pawl. The pawl is a pivot lever that engages with the teeth of the ratchet to lock the position. The foot pedal is connected to the support arm, which contains the ratchet. The pawl engages with the teeth of the ratchet, thereby holding the foot pedal in place. To adjust the foot pedal, the user can lift the foot pedal clockwise to raise it, where the ratchet allows this upward movement as its teeth slide past the pawl, thus gradually clicking into place. To lower the foot pedal, the user presses the release lever or button, which disengages the pawl from the gear, allowing free downward movement counterclockwise. The release lever re-engages the pawl, thereby securing the foot pedal in the desired position. This mechanism is user-friendly, providing fine control over adjustments and ensuring the foot pedal remains stable and locked in place once set. The foot pedal can also be adjusted during or after chair height adjustment, backrest tilt, etc. The chair can be used in various types of seating designed for ergonomic comfort, such as beauty chairs, barber chairs, treatment chairs, dental chairs, office chairs, and lounge chairs.

[0102] Several alternative mechanisms exist for adjusting footrests in various types of seating, which are not described in detail but are apparent to those skilled in the art. Gas spring or pneumatic mechanisms use compressed gas to provide smooth and effortless adjustment; the user can easily raise or lower the footrest by pressing a lever or button, common in office chairs and adjustable recliners. Another option is a manual locking pin system, which involves multiple preset holes along the support arm and a locking pin that can be inserted into any of the holes to secure the footrest. Screw and bolt adjustment mechanisms use threaded rods and handwheels or knobs to move the footrest up and down by turning the wheel, allowing for fine-tuning adjustments. Lever and cam mechanisms feature a rotating or sliding cam that locks in place at different points, where the user operates a lever to adjust the footrest. Electric adjustment mechanisms use a small motor controlled by a remote or built-in button to move the footrest to the desired position, providing effortless and precise adjustment (i.e., a dentist's chair). Friction hinge mechanisms provide adjustable resistance that holds the pedal in place without discrete locking positions; simply move the pedal to the desired angle and rely on the friction of the hinge to maintain that position. Telescopic mechanisms include nested tubes that slide inwards from each other, with locking collars or clamps to adjust the length of the pedal. Many other mechanisms exist that can replace the pedal for adjustment as needed.

[0103] Backrest: Figure 5 The image shows the tilted position of the chair back according to an embodiment. Many barbers use tilted chairs for shaving. The ability to tilt the chair back is a highly desirable feature. The ability to perform shaving or any kind of skin care is a good value for barbers.

[0104] The headrest 502 has multiple height adjustments to support the customer's head for shaving and any type of facial care when the backrest 504 is in an inclined position relative to the seat 506. According to an embodiment of the device, the device also includes a backrest, headrest, and footrest. According to an embodiment of the device, the backrest uses a gas spring to be adjustable to one or more inclined positions relative to the base. According to an embodiment of the device, the backrest can be folded onto the seat to form a closed position. According to an embodiment of the device, the backrest can be folded onto the seat and locked in the closed position. According to an embodiment of the device, the headrest can be adjusted to one or more height positions using a leaf spring mechanism.

[0105] Figure 6A mechanism for adjusting the tilt position of a chair backrest according to an embodiment is shown. The tilting movement of the backrest 602 utilizes a gas spring 604, which is attached to the chair backrest from the handle using a four-bar linkage 606. The backrest mechanism is characterized by the gas spring 604, which is concealed in the bottom / seat of the chair. The gas spring 604 applies forward pressure, causing the chair to be substantially pushed closed. The tilting mechanism of the backrest 602 may include three or more tilt positions, in which the mechanism can be locked. Figure 6 As shown in Figure A, the tilt is controlled by a button 608 on the side of the chair. The button 608 can be located anywhere on the chair that is convenient for the user to operate. Pressing the button 608 allows the chair to move forward to the folded position or further back to the tilted position. A four-bar linkage 606 allows the system to maintain tension, ensuring no wobbling or clicking during or after adjusting the backrest 602. This is also a safety measure to ensure the backrest does not accidentally open when the barber moves the chair in the traveling position, as the gas spring 604 applies forward pressure to push the chair closed. It also enhances the sense of luxury and sophistication for the user or the barber's client. When tilted, the gas spring provides controlled support, preventing sudden backward falls and ensuring a smooth, gradual tilt. This controlled movement improves the overall user experience. In the traveling or stored position, the backrest folds parallel to the seat, as... Figure 6 B and Figure 6 As shown in Figure C. The travel or storage position supports the equipment or chair in a compact location for storage or transport to different locations in the trunk of a car. The usage position refers to the position where the barber and customer use the chair together. In this embodiment, the gas spring 604 can be replaced by a hydraulic spring.

[0106] The backrest engages with the seat so that it can recline independently relative to the seat. In one embodiment, the backrest may not be detachable from the seat. In another embodiment, the backrest is detachable from the seat. The backrest is attached to the seat via one or more joints at 610 and is reclineable via a gas spring 604, as... Figure 6 As shown in D. Connector 610 can be replaced by any other connector that allows relative movement between the seat and the backrest.

[0107] Headrest: Figure 7 An adjustable headrest for a chair according to an embodiment is shown. The chair allows the user to change the height of the headrest 702. This ensures that it can accommodate people of different sizes and postures according to their seating preferences. This range 704 of height adjustability helps maintain proper alignment of the user's head and neck. The range 704 of height adjustability can be continuously varied, or it can have certain specific positions within the range where the headrest can be held in place.

[0108] In one embodiment, the headrest can be removed by releasing the elongated member 706 from the backrest 708, such as Figure 7 As shown in Figure A, the assembly includes a headrest 702, which is mounted on a backrest 708 during use. The headrest 702 includes an elongated member 706, one end of which slides into a headrest mounting device to be held in place within the backrest 708, as shown. Figure 7 As shown in Figure B, at the other end of the elongated member 706, there is a headrest pad for supporting the head of the person being served in the chair during use. The distance between the headrest 702 and the backrest 708 can be adjusted by sliding the elongated member 706 into and out of the headrest mounting device and locking it in place. Figure 8 use Figure 8 A, Figure 8 B Figure 8 C and Figure 8 D illustrates an example mechanism for adjusting a chair headrest according to an embodiment. The headrest is characterized by a leaf spring mechanism 802, which allows it to have, for example, Figure 8 As shown in Figure D, multiple steps or positions 804 are available without requiring the user to push any buttons or pull levers to minimize contact points. The number of positions 804 of the adjustable headrest 806 can be designed as needed.

[0109] In one embodiment, the headrest may be adjustable using a leaf spring mechanism. Other mechanisms may include a manually sliding mechanism in which the headrest moves along a track and is locked in place. In another embodiment, the headrest may include a ratchet mechanism that allows for gradual lifting and release when the headrest is raised to its highest point. In another embodiment, the headrest may use a button-release mechanism that uses a button or lever for easy adjustment. In another embodiment, the headrest may include a gas spring mechanism that employs a lever for smooth, controlled movement facilitated by the gas spring. In another embodiment, it may include an electrically adjustable mechanism in which a motor adjusts the headrest height via a control panel. The control panel may be a portable remote control or a fixed control panel on the chair. In the embodiments, any or all of the mechanical elements described herein for adjustment purposes may be replaced with suitable electronic components to facilitate automatic adjustment. Automation can be achieved by combining actuators, sensors, and electronic control systems. Adjustment can be managed via a control panel, which may include a user interface (such as a touchscreen, buttons, or dials) to allow for precise control and customization. The control panel can be integrated with a microcontroller or other processing unit that receives input from the user and activates corresponding electronic components to perform the desired adjustment. These electronic components can include, but are not limited to, electric motors, linear actuators, stepper motors, and solenoids, which can provide the necessary motion and positioning capabilities previously achieved through mechanical means. For example, when a mechanical lever is used to adjust the height of a chair, an electric motor coupled to a linear actuator can be used to achieve the same function. The user can set the desired height via the control panel, which sends a signal to the motor to move the actuator accordingly. Similarly, rotary adjustments previously managed by a manual knob can be replaced by a stepper motor controlled by an electronic system, providing precise and repeatable positioning. Replacing mechanical components with electronic counterparts not only improves ease of use and accuracy but also enables integration with intelligent systems, allowing for communication via wireless communication protocols (such as…). or It features remote control and automation.

[0110] Electronic components and control panels can be designed to integrate seamlessly with existing structures, thereby ensuring that the overall functionality and reliability of the system are maintained or enhanced. The transition from mechanical to electronic control systems can be achieved in a manner that allows for backward compatibility with the existing design and operation of the device and with minimal disruption.

[0111] Seat height adjustment: Figure 9 A hydraulic spring for seat height adjustment according to an embodiment is shown. Figure 9As shown in Figure A, the chair uses a hydraulic spring 902 for height adjustment. This is likely a part that can be readily available from an existing supplier. The hydraulic spring, configured for height adjustment, supports a rotating plate that provides the chair's rotatable / swivel motion. The hydraulic spring 902 includes a piston 904. The stroke length of the piston 904 determines the maximum height adjustment of the seat. A longer stroke length results in a greater height adjustment, and the user can select the stroke length based on the desired height adjustment. Furthermore, once the user is seated, the barber or service personnel can use lever 906 to easily adjust the height to a comfortable level, such as... Figure 9 A and Figure 9 As shown in B. The hydraulic spring 902 may also include an integral rotating plate and a mounting bracket 908. The mounting bracket 908 engages with a receiving member below the seat 910.

The legs are mechanically well-designed, allowing them to support the weight of the chair and the user while remaining stable without any swaying. Furthermore, they are designed to be very compact, enabling users to easily assemble, disassemble, and transport the chair to and from their customer sites. The feature of the hinge joint 1008 allows for a compact form of the hub while minimizing the number of steps required for user disassembly, as they only need to be folded. The legs will be locked with a spring-loaded pin or any other locking mechanism, such as a latch. The spring-loaded mechanism for locking also provides audible feedback to the user that the legs are locked by producing a simple click when the pin falls into place and locks the legs. They allow the user to fold the legs down into the open position, where they will lock in place with the help of the pin. The legs may include feet 1010, which are height-adjustable leveling feet 1012, such as... Figure 10 As shown in Figure A. This feature helps to level the chair when it is placed on a non-level floor. The legs are characterized by rubber feet, which are also height-adjustable to provide stability on uneven surfaces, and these rubber feet further act as shock absorbers when the user sits on the chair or when the chair is adjusted. When the user is finished using the chair, they will unlock the legs and pull them back, as shown in Figure A. Figure 10 As shown in B, put them in a bag.

[0115] The support assembly or base assembly also includes legs 1006 for supporting the chair in use (only a few legs 1006 are indicated where appropriate in the drawings for ease of reference). The legs 1006 are foldable from an extended position (in which the legs extend laterally from the support assembly to support the chair in use) to a folded position (in which the legs rest against the outer member of the hydraulic spring). The legs 1006 are pivotally attached at their proximal ends to the lower (closed) end of the outer member and are lockable in both the extended and folded positions by a locking pin. The legs include chair feet at their distal ends for supporting the chair in use; the feet screw into the distal ends of the legs. This allows for depth adjustment of the feet relative to the legs to level the chair's height. The number of legs 1006 is not critical, but must be sufficient to provide adequate stability for the chair in use. In embodiments, the base assembly includes one or more foldable legs.

The seat also includes a first side and a second side, the first side including a leg rest, and the second side including one or more wheels. The backrest engages with the seat so as to be independently tilted relative to the seat and folded onto the upper side of the seat to lie substantially flat with the seat. The support assembly includes: a seat engagement device for releasably engaging with the lower side of the seat; a hydraulic spring configured for height adjustment to hydraulically raise and lower the height of the seat and backrest assembly in use; and one or more legs foldable between an extended position (in which the legs extend laterally from the support assembly to support the grooming chair in use) and a folded position (in which the legs rest against or adjacent to a hydraulic spring configured for height adjustment).

[0150] This invention provides an assembly for assembling a grooming chair for individuals to sit and receive personal grooming services (such as a haircut). The assembly can be compactly packaged (preferably in a box or bag) and transported to the grooming location in the trunk of a passenger vehicle (preferably a sedan or hatchback, e.g., a compact or larger vehicle according to the Association of Car Rental Industry Systems (ACRISS) vehicle classification code) without folding down the rear seats, and can be quickly and easily assembled into a grooming chair in place. Preferably, the assembly weighs 25 kg or less for personal transport. Preferably, the assembly can be assembled and disassembled without tools, for example, through quick-release locking mechanisms and self-locking mechanisms. However, when assembled, a grooming chair functions like a conventional grooming chair found in, for example, hair salons or barbershops; that is, the seat and backrest assemblies are height-adjustable, and the backrest can tilt relative to the seat. All these functions are available even when a child or adult is occupied, preferably someone weighing up to 120 kg (which is typically the maximum load for a grooming chair). In contrast, a typical office swivel chair, for example, is only height-adjustable when not in use, making it unsuitable for use as a grooming chair.

[0151] The assembly of the present invention is portable and the materials used to manufacture it should preferably be selected to minimize weight. Suitable materials may include low-carbon steel tubing (e.g., for the frame), stainless steel (e.g., for the locking components), aluminum (i.e., for the frame and locking mounts), chrome-plated metal, polypropylene and / or plywood (i.e., for the seat or backrest base), nylon (i.e., for the locking components), seat foam, and nylon covering material (i.e., for the padding components).

[0152] The assembly of the present invention preferably further includes a carrying device and / or a storage device for accommodating the disassembled assembly for transport from one location to another and / or for storage when no longer in use. For example, the carrying device and / or storage device may include one or more of a travel bag, a cover, or a foam-filled box, wherein the foam includes recesses into which different components of the assembly can be placed. The recesses may be customized to the specific shape of the components, for example, through computer numerical control (CNC) wiring.

[0153] Assembling the components into a grooming chair can be done according to the user's convenience and does not require any particular order of assembly. However, the possible sequence of actions is as follows: For assembly: the legs are unfolded from the folded position to the extended position and preferably locked in place, which can be done automatically, and where appropriate, the feet are also attached to or unfolded from the legs so that the legs can be securely positioned on the floor. If appropriate, the position of the feet relative to the legs can be adjusted, for example by screwing the feet into / out of the legs, to level the height of the chair. The mounting bracket engages with a receiving member (groove) on the underside of the seat in the upright / vertical position. For example, in a preferred embodiment, the receiving member on the underside of the seat can be placed on the mounting bracket, slid, and folded into a locked position, which is a horizontal position. The seat, with its attached backrest forming the seat assembly, can be unfolded from its folded position. The armrests, headrest, and / or footrest, which are already part of the seat assembly, can also be adjusted to the desired height and angle.

[0154] Once assembled, the client can sit in the grooming chair and make any adjustments to its position as needed, such as raising the seat and backrest, raising or lowering the headrest, and tilting the backrest. All these adjustments can be made while the client is seated. The seat and backrest assemblies rotate on the support assembly.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein best explains the principles of the embodiments, their practical application, and / or technical improvements to existing technologies in the market, and / or enables others skilled in the art to understand the embodiments described herein.
