Description

Technical Field

[0001] This utility model relates to the field of wheelchair assistive technology, and in particular to a retractable and replaceable pocket component installed on the armrest of a wheelchair, suitable for storing small personal items such as beverage bottles and mobile phones. Background Technology

[0002] Wheelchair users typically need to carry small items such as mobile phones, beverage bottles, tissues, and medicine boxes during daily outings. Existing technologies offer various side pockets, hanging bags, or cup holders for wheelchairs, using straps, buckles, or Velcro to secure soft bags to the armrests or frame, creating storage space. However, these technologies still have the following shortcomings: the storage devices protrude from the side of the wheelchair, making them prone to snagging or collisions when passing through narrow passages, doorways, or public facilities, taking up space and affecting aesthetics; many structures require two-handed operation or use snaps or buckles, which demand significant hand strength, making them unsuitable for wheelchair users with insufficient upper limb strength or those who can only operate with one hand; the bags are often sewn together and fixed to the armrests or frame, making them difficult to disassemble and wash, and difficult to flexibly replace with different functional or form-specific bags according to different usage scenarios; some structures lack effective protection for the armrest surface after installation, easily causing wear and tear. Therefore, there is a need for a pocket assembly for wheelchair armrests that is simple in structure, easy to operate with one hand, can be stored in a basically flat state when not in use, and has easily replaceable pockets, in order to overcome the above-mentioned shortcomings. Utility Model Content

[0003] The technical problem this utility model aims to solve is to provide a retractable and replaceable pocket component for wheelchair armrests, addressing the following defects of existing wheelchair armrest side-hanging storage bags: 1) Difficult to store and constantly protruding on one side: Existing wheelchair armrest side bags are mostly fixed hanging structures. Even when no items are needed, the bag continues to protrude from the side of the armrest, easily scraping or snagging against surrounding objects when passing through narrow passages, near tabletops, or bedside, affecting safety and passage. 2) Inconvenient operation and disadvantageous to one-handed users: Existing structures often require both hands to operate when unfolding, folding, or disassembling. For wheelchair users with limited upper limb strength or who can only operate with one hand, it is difficult to unfold and store the bag, resulting in a poor user experience. 3) Poor adaptability and difficulty in compatibility with wheelchair armrests of different diameters: Different wheelchair models have different armrest diameters. Existing side bags are generally designed for specific sizes and cannot adapt to armrests of different diameters within a wide range, resulting in poor universality of the same storage component, unstable installation, or unsatisfactory installation. 4) Inconvenient replacement and cleaning, and limited protection for armrests: Some wheelchair side pockets cannot be easily removed, affecting the cleaning and replacement of the pockets; at the same time, the armrest surface lacks an effective cushioning structure, providing insufficient protection against wear and tear on the armrest body and insufficient cushioning support for the user's elbows. Based on the above problems, this utility model proposes a wheelchair armrest pocket assembly that is simple in structure, easy to install, can quickly switch between a usable state and a flat storage state, can adapt to wheelchair armrests of different diameters, and is easy to operate and replace with one hand, while also providing soft padding protection for the armrests.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a retractable and replaceable pocket assembly for a wheelchair armrest (7), comprising: 1) a fixing strap portion: the fixing strap (1) extends in a strip shape along a first direction, preferably a long strip of flexible material, the length of which is sufficient to wrap around the outer periphery of the wheelchair armrest (7) one or more times. The inner side of the fixing strap (1) is provided with a first adhesive portion (11) and a second adhesive portion (12) opposite to each other along its length direction, such as hook and loop fasteners that cooperate with each other, for detachably adhesively fixing the opposite parts of the fixing strap (1) together after the fixing strap (1) wraps around the wheelchair armrest (7), so that the fixing strap (1) is stably fixed to the outer periphery of the wheelchair armrest (7).

[0005] Preferably, a buffer layer (4) is provided on the inner side of the fixing strap (1). The buffer layer (4) is a soft material, such as foam or sponge, which can be fixed to the inner surface of the fixing strap (1) by bonding or sewing. It is used to provide soft padding protection for the outer periphery of the wheelchair armrest (7) when the fixing strap (1) surrounds the wheelchair armrest (7) to improve the comfort of use.

[0006] Preferably, to facilitate single-handed operation when the bag is stored or unfolded, the outer surface of the fixing strap (1) is provided with an operating protrusion (5). The operating protrusion (5) protrudes outward relative to the adjacent part of the fixing strap (1). When the bag (2) is wrapped around the outside of the fixing strap (1) or unfolded from the outside of the fixing strap (1), the user's fingers can rest against or pinch the operating protrusion (5) to apply rotational torque to the fixing strap (1) and the bag (2). The outline shape of the operating protrusion (5) can be a basic T-shape, an arc shape, or other shapes that are easy for the fingers to rest against, and this utility model does not limit this.

[0007] 2) Bag piece part: The bag piece (2) includes a connecting part (21) at the upper end and a bag body part (22) at the lower end. The connecting part (21) is fixed to the side of the fixing strap (1) located at the lower end in the installed state, so that the bag piece (2) extends downward from the fixing strap (1).

[0008] Preferably, the connecting part (21) is connected to the fixing strap (1) through a detachable connecting structure, so that the bag piece (2) can be detached and replaced relative to the fixing strap (1). The detachable connecting structure is used to realize the detachable fixed connection between the connecting part (21) and the fixing strap (1), and can be in the form of, but not limited to, zippers, Velcro, snaps, buckles, snap fasteners, hooks and loops, or combinations of the above forms. This utility model does not limit this.

[0009] The bag body (22) is located below the connecting part (21), and its lower end and side edges are sealed by stitching or other sealing methods to form an upward-facing receiving cavity (220) for storing beverage bottles, mobile phones or other small personal items. The bag body (22) is preferably made of flexible material, which can naturally form a bag-shaped structure when unfolded, and can be bent and fitted with the fixing strap (1) when stored.

[0010] To further facilitate one-handed operation, preferably, the lower end of the bag piece (2) is provided with a pull-hold portion (6). The pull-hold portion (6) extends outward relative to the adjacent edge of the bag body (22). When the bag piece (2) is flipped from the folded state to the unfolded state or rolled from the unfolded state to the folded state, the user can grasp or hook the pull-hold portion (6) to drive the bag piece (2) to move. The pull-hold portion (6) may be formed with a through hole for the user's fingers to pass through or to cooperate with the hook, or it may be a protruding tongue without a hole. This utility model does not limit this.

[0011] In addition, in order to adapt to wheelchair armrests (7) of different diameters, the length of the bag (2) is set such that when installed on wheelchair armrests (7) of different diameters, the bag (2) can wrap around the outer surface of the fixing strap (1) 1 to 3 times and can still be fixed by the fastening part (3) and the fastening corresponding part (32).

[0012] 3) Fastening structure: The fastening part (3) and the corresponding fastening part (32) are used to fix the bag piece (2) in the storage position when the bag piece (2) is in the storage state. The fastening part (3) is provided at the end of the bag body (22) away from the fixing strap (1), and is usually located in the lower end area of ​​the bag body (22); the corresponding fastening part (32) is provided on the back of the bag body (22) and located in the middle area, so that when the bag piece (2) is wrapped around the fixing strap (1) for storage, the fastening part (3) can be opposite to the corresponding fastening part (32) and fasten.

[0013] Preferably, a first magnetic element (31) is provided on the fastening part (3), and a second magnetic element (321) is provided on the corresponding fastening part (32). The two are magnetically attracted to form a reliable fastening. When the bag piece (2) is wrapped around the outside of the fixing strap (1) to a predetermined number of turns, the first magnetic element (31) and the second magnetic element (321) attract each other to achieve fixation in the storage state.

[0014] 4) Material selection: Preferably, the fixing strap (1) is made of flexible material, such as flexible webbing, composite fabric or elastic material; the bag body (22) is made of flexible material, such as cloth, mesh or flexible sheet, etc., and materials with waterproof, breathable or wear-resistant properties can be selected according to the usage scenario. The overall structure is mainly composed of common components such as webbing, cloth, adhesive parts, and magnetic parts. The manufacturing process is simple and suitable for mass production. This utility model does not limit the specific types of materials.

[0015] In the use of this utility model, in the unfolded state, the fastening part (3) and the fastening corresponding part (32) are released, and the bag piece (2) hangs down naturally from the outer surface of the fixing strap (1) along the direction of gravity, and the receiving cavity (220) forms a space for placing beverage bottles, mobile phones or other items; in the stored state, the bag piece (2) is wrapped around the outer surface of the fixing strap (1) at least once, and is fixed to the outer surface of the bag piece (2) by the detachable fastening of the fastening part (3) and the fastening corresponding part (32) arranged on the back of the bag body, so that the receiving cavity (220) is basically flat against the outer side of the fixing strap (1), which helps to reduce the amount of the component protruding outward.

[0016] Compared with existing technologies, the retractable and replaceable pocket assembly for wheelchair armrests provided by this utility model has at least the following beneficial effects: It achieves a rolled-up, flat storage of the pocket, significantly reducing the risk of lateral protrusion and snagging. By setting a flexible fixing strap that can be wrapped around the wheelchair armrest and a pocket piece that can be wrapped around the outer surface of the fixing strap 1-3 times, when the pocket piece is not used for storing items, it is rolled up along the outside of the fixing strap, and the fastening part of the pocket body magnetically engages with the corresponding fastening part on the back, so that the formed receiving cavity is close to the outside of the fixing strap and is basically flat. Therefore, in the stored state, the pocket assembly hardly protrudes significantly outward from the armrest, reducing the risk of scratching or snagging with walls, table edges, bed edges, or other objects, and improving wheelchair maneuverability and safety.

[0017] With the aid of the operating protrusion and the pull part, the unfolding and folding operations can be quickly completed with one hand: the operating protrusion is set on the outside of the fixing strap, and the pull part extends outward at the lower end of the bag. The user can grasp the pull part and press against or grasp the operating protrusion to apply force to the bag to roll or flip it, realizing the switching from unfolded to rolled-up and from folded to unfolded states. The entire process has a clear action path and a clear force point, which is suitable for wheelchair users with limited upper limb strength or those who can only operate with one hand, significantly improving the convenience and user-friendliness of actual use.

[0018] The length of the bag piece, combined with the magnetic fastening structure, expands its adaptability to armrests of different diameters. The length of the bag piece is specifically designed so that, when installed on armrests of different diameters, the bag piece can wrap around the outer surface of the fixing strap 1-3 times, and the fastening part at the end of the bag body away from the fixing strap can still align with the corresponding fastening part in the middle of the back of the bag body and reliably fasten via magnetic attachment. This magnetic adsorption fastening eliminates the need for precise alignment and complex structures, maintaining good storage stability and reliability across a wide range of diameter variations, thereby improving the versatility of this invention for different types of wheelchair armrests.

[0019] The cushioning layer and the flat storage shape work together to provide soft protection for the armrests and the user's elbows: A cushioning layer is set on the inside of the fixing strap. After the components are installed around the wheelchair armrests, the cushioning layer fits against the outer periphery of the armrests. When the bag is rolled up and stored in a flat shape, a soft padding area of ​​appropriate thickness is formed on the outer periphery of the armrests. This reduces hard wear on the surface of the armrests and provides a softer and more comfortable support contact surface for the user's elbows, improving the riding experience.

[0020] The detachable connection structure makes the bag panels easy to replace and clean, enhancing hygiene and functional expandability: The connecting part of the bag panel is connected to the fixing strap through a detachable connection structure, allowing users to quickly remove the bag panels for cleaning or replacement with different functions, materials, and appearances as needed. For example, when more storage space, specific item partitioning, or a specific style is required, different bag panel components can be selected for replacement, increasing the product's flexibility in hygiene maintenance and personalized use.

[0021] Simple structure, moderate cost, easy to mass production and promotion: This utility model is mainly composed of flexible fixing strap, bag, magnetic fastener, buffer layer and simple connector. The structure is relatively simple and clear, without the need for complex metal brackets or multi-degree-of-freedom mechanical parts. The manufacturing and assembly process is easy to realize, and it is suitable for large-scale promotion and application in wheelchair products of different grades and types.
