Description

A support and restraint device for disabled people inside an elevator car Technical Field

[0001] This utility model belongs to the field of elevator leaning assistance technology, and in particular relates to a leaning and fixing device for disabled people in an elevator car. Background Technology

[0002] Elevators, as essential auxiliary facilities for going up and down in high-rise buildings and public places, have become increasingly widespread, and more and more people are enjoying the convenience they bring. However, during the elevator's ascent and descent, especially in the short period before and after starting and stopping, the elevator often experiences brief swaying due to braking, lifting, and other operations of the machine room's drive equipment. Elevator passengers often cannot accurately predict the exact timing of this swaying, thus frequently experiencing brief discomfort and loss of balance during the ride. This is particularly true for people with disabilities, whose physical limitations make the impact of this swaying more pronounced, and it may even cause them to lose their balance and fall, resulting in injury.

[0003] To address this issue, existing technologies have made some attempts and improvements. For example, Chinese utility model patent CN215592291U proposes a support and fixing device for disabled persons in an elevator car, which provides further support points for disabled persons through a foldable handrail. However, this existing technology has certain limitations. Because it is fixedly installed on the plane of the car, the unfolded handrail occupies a large area, which not only takes up too much car space but also easily disturbs and affects other passengers. At the same time, the device can only provide a simple support point; the legs of disabled persons cannot be fully relaxed, and during long rides, disabled persons will still feel tired and uncomfortable.

[0004] Therefore, it is essential to invent a support and fixation device for disabled people inside an elevator car. Summary of the Invention

[0005] To address the aforementioned technical problems, this utility model provides a support and fixing device for disabled persons inside an elevator car, comprising a car mounting plate, a backrest cushion, mounting holes, a storage slot, a hinge, a folding seat, a fastening slot, a reinforcing support plate, a limiting opening, and a mounting component. The backrest cushion is installed at the inner corner of the car mounting plate, and the mounting component passes through the mounting holes on the car mounting plate itself, fixing the car mounting plate to the inner corner of the car. A storage slot is mirror-image-formed on the inner side below the car mounting plate, and the folding seat is connected to the car mounting plate via a hinge located in the storage slot. Each folding seat has a fastening slot. Two reinforcing support plates are rotatably mounted below the car mounting plate, and a limiting opening is provided on the inner side below the car mounting plate.

[0006] Preferably, the car mounting plate has an "L" shaped structure, and the inner side of the backrest installed at the inner corner of the car mounting plate is an arc-shaped curved surface, with the backrest located above the two storage slots.

[0007] Preferably, the storage slot allows the folded seat to be stored, the folded seat allows to move along the hinge in an arc-shaped trajectory, and the buckle provided on the folded seat folded into the storage slot allows a portion of it to be exposed, allowing fingers to be inserted.

[0008] Preferably, the two folding seats are arranged correspondingly, and the folding seats are fan-shaped. The two folding seats allow a seat that can be leaned against by a person with disabilities in the area below the inner corner of the car mounting plate.

[0009] Preferably, each of the folding seat panels is inlaid with a magnet that can attract the car mounting plate, and the two folding seat panels are installed in a mirror-symmetrical arrangement without interfering with each other.

[0010] Preferably, the folding seat is supported by two reinforcing brackets rotatably mounted below the car mounting plate, the reinforcing brackets being located below the folding seat.

[0011] Preferably, the limiting opening on the lower inner side of the car mounting plate allows the edge of the folding seat to enter, the folding seat can smoothly enter and exit the limiting opening, and the limiting opening can restrict the folding seat from moving further downward.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model provides a support and fixing device for disabled persons inside an elevator car. The car mounting plate adopts an "L"-shaped structure and is installed at the inside corner of the car. Compared with existing devices installed on the car's surface, this effectively reduces space occupation, avoids interference and impact on other passengers, and makes full use of the car's space, improving its utilization rate. The inner side of the support pad installed at the inner corner of the car mounting plate is curved, conforming to the curve of the human back, providing a more comfortable support experience for disabled persons and alleviating their discomfort when the elevator sways. In addition, its location at the inside corner reduces the risk of expansion and compression for disabled persons, further ensuring their safety.

[0014] This utility model's folding seat is connected to the car mounting plate via a hinge and can be moved along the hinge in an arc-shaped trajectory to be stored in the storage slot. When not in use, the folding seat is stored in the storage slot without occupying car space; when in use, the folding seat is unfolded, and the two folding seats can form a support area below the inner corner of the car mounting plate, allowing people with disabilities to lean against the seat, so that their legs can be supported and relaxed, reducing physical fatigue.

[0015] This utility model features a reinforcing support plate beneath the folding seat. When the folding seat is unfolded, the reinforcing support plate supports and lifts it, enhancing its load-bearing capacity and ensuring safety for users with disabilities. Furthermore, a limiting opening on the lower inner side of the car mounting plate restricts further downward movement of the folding seat, making it more stable in its unfolded state and providing reliable support for users with disabilities, further improving the safety and stability of the device.

[0024] As shown in Figures 1 to 4:

[0025] This utility model provides a support and fixing device for disabled persons in an elevator car, including a car mounting plate 1, a backrest cushion 2, a mounting hole 3, a storage groove 4, a hinge 5, a folding seat 6, a fastening groove 7, a reinforcing support plate 8, a limiting opening 9, and a mounting component. The backrest cushion 2 is installed at the inner corner of the car mounting plate 1. The mounting component passes through the mounting hole 3 provided on the car mounting plate 1 to fix the car mounting plate 1 at the inner corner of the car. The storage groove 4 is mirror-image-opened on the inner side below the car mounting plate 1. The folding seat 6 is connected to the car mounting plate 1 through the hinge 5 provided at the storage groove 4. Each folding seat 6 has a fastening groove 7. Two reinforcing support plates 8 are rotatably installed below the car mounting plate 1. The limiting opening 9 is provided on the inner side below the car mounting plate 1.

[0026] Furthermore, the car mounting plate 1 has an "L" shaped structure, made of stainless steel sheet bent into shape in one piece to ensure structural strength and rust resistance. A backrest pad 2 is installed on the inner corner of the car mounting plate 1 using strong adhesive. The inner surface of the backrest pad 2 is curved, made of high-density memory foam covered with non-slip, breathable PU leather. The backrest pad 2 is located directly above the two storage slots 4, maintaining a distance of 10-15cm from the edge of the storage slots 4, ensuring that the user's back does not interfere with the folding components when leaning against it.

[0027] Furthermore, the storage slot 4 is located on the inner side below the car mounting plate 1, and its depth is less than the thickness of the folding seat plate 6, facilitating the exposure of the subsequent fastening slot 7. This slot is laser-cut and rounded at the corners. The folding seat plate 6 is rotatably connected to the car mounting plate 1 via a hinge 5, allowing it to move along a 90° arc trajectory along the hinge 5. When folded for storage, the upper edge of the fastening slot 7 on the folding seat plate 6 is exposed at the opening of the storage slot 4, making it easy to insert fingers and apply force to unfold it.

[0028] Furthermore, the two folding seat panels 6 are arranged in a mirror-symmetrical manner, both being fan-shaped panels made of ABS engineering plastic injection molding. When unfolded, the two folding seat panels 6 are spliced ​​together below the inner corner of the car mounting plate 1 to form a continuous resting surface, with the edges wrapped with silicone strips to prevent bumps and knocks.

[0029] Furthermore, each folding seat 6 has four neodymium iron boron magnets embedded in its surface, corresponding to the magnetic iron plates pre-embedded on the inner side of the car mounting plate 1, ensuring a stable and close fit when folded. The distance between the mounting shafts of the two folding seat 6 is precisely controlled within ±0.5mm, enabling independent opening and closing without interference.

[0030] Furthermore, the reinforcing support plate 8 is rotatably connected to the underside of the car mounting plate 1 via a concealed damping pivot, and is made of cold-rolled steel sheet by stamping and powder coating. When the folding seat plate 6 is unfolded to a horizontal state, the reinforcing support plate 8 can be flipped to form support under the folding seat plate 6. The surface of the reinforcing support plate 8 is provided with anti-slip rubber pads, and the contact area with the bottom surface of the folding seat plate 6 is ≥70%.

[0031] Furthermore, the limiting port 9 is located on the lower inner side of the car mounting plate 1, and is a U-shaped groove structure. The groove wall is CNC milled to ensure precision. The edge of the folding seat plate 6 is provided with a protruding ridge that matches the limiting port 9. When the folding seat plate 6 is unfolded into place, the protruding ridge is embedded in the limiting port 9 to form a mechanical limit, ensuring the stability of the folding seat plate 6 while avoiding rigid impact.

[0032] The working principle is as follows: When a person with a disability enters the elevator, if they need to lean against something to rest, they can insert their fingers into the exposed slots 7 of the folding seat 6 when it is in its folded state, and apply force along the 90° arc trajectory of the hinge 5 to unfold the seat. After the two fan-shaped folding seat 6 are unfolded symmetrically, they are spliced ​​together to form a continuous plane below the inner corner of the car mounting plate 1, allowing the user to lean against something or sit down briefly.

[0033] When fully unfolded, the protruding edges of the folding seat 6 automatically engage with the limiting slots 9 to form a mechanical limit, preventing the seat from wobbling; simultaneously, the reinforcing support plate 8 flips over to the bottom of the seat, with its anti-slip rubber pad having a contact area of ​​over 70% with the bottom surface of the seat, providing stable support. The curved memory foam surface of the backrest cushion 2 conforms to the back, reducing lumbar pressure when standing.

[0034] After use, lift the seat plate upwards to disengage it from the limiting slot 9, fold it back into the storage slot 4 along the hinge 5, and simultaneously reset the reinforcing support plate 8. The neodymium iron boron magnets on the surface of the folded seat plate 6 automatically attract and fix it to the magnetic iron sheet of the car mounting plate 1, with the buckle slot 7 partially exposed for easy retrieval next time. The entire device achieves the effect of space-saving storage and stable support when unfolded through the triple protection of mechanical limiting, magnetic fixation, and damping support, adapting to the swaying environment during elevator start-up and stop.

[0035] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
