Description

Technical Field

[0001] This application relates to the field of elevator technology, and in particular to an elevator car anti-fall structure. Background Technology

[0002] As society ages, the elderly and patients have weaker mobility and are more prone to discomfort or even falls when using elevators due to standing for too long.

[0003] Currently, most elevator cars do not have seats specifically designed for passengers with mobility impairments, leaving these individuals without necessary support and safety when riding elevators. Therefore, there is an urgent need for an elevator car structure that can prevent these passengers from falling. Summary of the Invention

[0004] To reduce the risk of passengers falling, this application provides an elevator car anti-fall structure.

[0005] This application provides an elevator car anti-fall structure, which adopts the following technical solution:

[0006] An elevator car anti-fall structure includes:

[0007] The car;

[0008] The mounting plate is fixedly installed on the side wall of the car.

[0009] Seat plate, hinged to the mounting plate;

[0010] A limiting component is used to lock the position of the base plate so that the base plate is in a vertical position;

[0011] The load-bearing component is connected to the seat plate and is used to bear the pressure on the seat plate.

[0012] By adopting the above technical solution, elderly people or patients with impaired mobility can release the restriction of the seat board by the limiting component, rotate the seat board to a horizontal position, and then sit on the seat board without having to stand in the car for a long time, thereby achieving the purpose of preventing falls. After use, the seat board can be rotated upward to make the limiting component limit the position of the seat board, so that the seat board remains in a vertical state, reducing the space occupied by the seat board in the car.

[0013] Optionally, a hinge shaft is fixedly provided at one end of the seat plate near the mounting plate, the hinge shaft is rotatably connected to the mounting plate, and a reset member for driving the seat plate to deflect upward is provided between the seat plate and the mounting plate.

[0014] By adopting the above technical solution, when not in use, the reset component can automatically drive the seat plate to tilt upwards to a vertical position, preventing the user from forgetting to rotate the seat plate upwards and causing the seat plate to be in a horizontal position. After use, the seat plate will automatically tilt upwards, which also makes it easier for the limiting component to limit the position of the seat plate.

[0015] Optionally, the limiting component includes a mounting block, an elastic element, and a limiting pin. The mounting block is fixedly mounted on the mounting plate. The mounting block has a mounting groove on its side wall near the base plate. The limiting pin is slidably disposed in the mounting groove. The base plate has an arc-shaped groove on its side wall near the mounting block for the insertion of the limiting pin. One end of the limiting pin has a spherical portion that matches the arc-shaped groove. The elastic element is disposed in the mounting groove to drive the limiting pin to move outward.

[0016] By adopting the above technical solution, after use, the base plate automatically tilts upward at a certain angle under the action of the reset component. Then, the base plate is manually pushed to a vertical position. When the base plate contacts the spherical part of the limit pin, the limit pin is gradually pushed into the mounting groove. When the arc-shaped groove is aligned with the mounting groove, the limit pin is inserted into the arc-shaped groove under the action of the elastic component. At this time, the position of the base plate is limited, maintaining a vertical storage state, reducing the space occupied, and the base plate storage operation is simple and convenient.

[0017] Optionally, the force-bearing component includes two force-bearing ropes, which are respectively connected to both sides of the seat plate. One end of each force-bearing rope is fixedly connected to the mounting plate, and the other end is fixedly connected to the side wall of the seat plate.

[0018] Optionally, the upper surface of the seat plate is provided with an arc-shaped groove.

[0019] Optionally, the top of the car is provided with handles.

[0020] Optionally, the car is equipped with a pull rope, one end of which is fixedly connected to the handle, and the side wall of the car is equipped with an adjustment component for adjusting the length of the pull rope.

[0021] By adopting the above technical solution, the length of the pull rope can be adjusted by adjusting the components, thereby adjusting the height of the handle to accommodate passengers of different heights and increase applicability.

[0022] Optionally, the adjusting assembly includes a worm gear, a worm, and a winding wheel. A pulley is rotatably mounted on the top wall of the car, the pull rope is wound around the pulley, the winding wheel is rotatably mounted on the side wall of the car, the end of the pull rope away from the handle is wound around the winding wheel, the worm gear is coaxially and fixedly connected to the winding wheel, the worm is rotatably mounted on the car, and the worm meshes with the worm gear.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When using the car, elderly people or patients with limited mobility can release the restriction of the seat board by removing the limiting component, rotate the seat board to a horizontal position, and then sit on the seat board. There is no need to stand in the car for a long time, thus achieving the purpose of preventing falls. After use, rotate the seat board upward to make the limiting component limit the position of the seat board, so that the seat board remains in a vertical state and reduces the space occupied by the seat board in the car.

[0025] 2. After use, the seat plate automatically tilts upwards at a certain angle under the action of the reset component. Then, manually push the seat plate to a vertical position. When the seat plate contacts the ball part of the limit pin, gradually push the limit pin into the mounting groove. When the arc groove is aligned with the mounting groove, the limit pin is inserted into the arc groove under the action of the elastic component. At this time, the position of the seat plate is limited, maintaining a vertical storage state, reducing the space occupied. The seat plate storage operation is simple and convenient.

[0026] 3. The length of the pull rope can be adjusted by adjusting the component, thereby adjusting the height of the handle to accommodate passengers of different heights and increase its applicability. Attached Figure Description

[0037] This application discloses an elevator car anti-fall structure.

[0038] Reference Figure 1 An elevator car anti-fall structure includes a car 1, a mounting plate 2, a seat plate 3, and a load-bearing component 22.

[0039] The mounting plate 2 is fixedly installed on the side wall of the car 1. The mounting plate 2 can be made of stainless steel or plastic. In order to improve the firmness of the mounting plate 2, the mounting plate 2 is fixed to the side wall of the car 1 with screws.

[0040] Optional, refer to Figure 1 and Figure 2 The seat plate 3 is hinged to the mounting plate 2, and an arc-shaped groove 31 is formed on the upper surface of the seat plate 3. Two ear plates 21 are fixedly installed on the mounting plate 2. A hinge shaft 32 is fixedly installed at one end of the seat plate 3 near the mounting plate 2. The hinge shaft 32 is rotatably connected to the mounting plate 2, and both ends of the hinge shaft 32 are respectively rotatably inserted into the two ear plates 21. A reset member 321 for driving the seat plate 3 to deflect upward is provided between the seat plate 3 and the mounting plate 2. The reset member 321 is a torsion spring, which is sleeved on the hinge shaft 32. One end of the torsion spring is fixedly connected to the seat plate 3, and the other end is fixedly connected to the ear plate 21. When not in use, the reset member 321 can automatically drive the seat plate 3 to deflect upward to a vertical position, preventing the user from forgetting to rotate the seat plate 3 upward and causing the seat plate 3 to be in a horizontal position. After use, the seat plate 3 automatically deflects upward, which also facilitates the limiting component 4 to limit the position of the seat plate 3.

[0041] In this embodiment, the distance between the ear plate 21 and the bottom of the car 1 is 500mm-800mm, so that when the seat plate 3 is in a horizontal state, the height from the ground is moderate, making it easy for the elderly and children to sit down.

[0042] The force-bearing component 22 is connected to the seat plate 3 and is used to bear the pressure on the seat plate 3. The force-bearing component 22 includes two force-bearing ropes, which are respectively connected to both sides of the seat plate 3. When the force-bearing ropes are taut, the seat plate 3 is in a horizontal state. One end of the force-bearing rope is fixedly connected to the mounting plate 2, and the other end is fixedly connected to the side wall of the seat plate 3.

[0043] Optional, refer to Figure 3 and Figure 4The limiting component 4 is used to lock the position of the seat plate 3 so that the seat plate 3 is in a state where a person can sit down. The limiting component 4 includes a mounting block 41, an elastic element 42, and a limiting pin 43. The mounting block 41 is fixedly set on the mounting plate 2. Two mounting blocks 41 are provided. The distance between the two mounting blocks 41 is equal to or slightly greater than the width of the seat plate 3, so that the seat plate 3 can just rotate between the two mounting blocks 41. The mounting block 41 has a mounting groove 411 on the side wall near the seat plate 3. The limiting pin 43 is slidably set in the mounting groove 411. The seat plate 3 has an arc-shaped groove 33 on the side wall near the mounting block 41 for the insertion of the limiting pin 43. One end of the limiting pin 43 is provided with a spherical part 431 that matches the arc-shaped groove 33. The spherical part 431 is generally hemispherical. The elastic element 42 is disposed in the mounting groove 411 to drive the limiting pin 43 to move outward. The elastic element 42 is a spring. One end of the spring is fixedly connected to the bottom wall of the mounting groove 411, and the other end is fixedly connected to the limiting pin 43. When the spring is at its original length, the spherical part 431 of the limiting pin 43 is just outside the mounting groove 411. When the seat plate 3 deflects and contacts the spherical part 431, it will press the limiting pin 43 inward so that the seat plate 3 can rotate smoothly to the vertical state.

[0044] After use, under the action of the reset member 321, the seat plate 3 automatically tilts upward at a certain angle. Then, the seat plate 3 is manually pushed to a vertical position. When the seat plate 3 contacts the ball part 431 of the limit pin 43, the limit pin 43 is gradually pushed into the mounting groove 411. When the arc groove 33 is aligned with the mounting groove 411, the limit pin 43 is inserted into the arc groove 33 under the action of the elastic member 42. At this time, the position of the seat plate 3 is limited, maintaining a vertical storage state, reducing the space occupied. The storage operation of the seat plate 3 is simple and convenient.

[0045] Optional, refer to Figure 1 A handle 5 is provided on the top of the car 1, and a pull rope 51 is provided on the car 1, with one end of the pull rope 51 fixedly connected to the handle 5. A pulley 11 is rotatably provided on the top wall of the car 1, and a guide wheel 12 is provided on the top of the side wall of the car 1. The pull rope 51 is wound around the pulley 11 and the guide wheel 12 in sequence.

[0046] Reference Figure 1 and Figure 5 The side wall of the car 1 is provided with an adjusting assembly 6 for adjusting the length of the pull rope 51. The adjusting assembly 6 includes a worm gear 61, a worm 62, and a winding wheel 63. The winding wheel 63 is rotatably mounted on the side wall of the car 1. The end of the pull rope 51 away from the handle 5 is wound around the winding wheel 63. The worm gear 61 is coaxially and fixedly connected to the winding wheel 63. The worm 62 is rotatably mounted on the car 1 and meshes with the worm gear 61.

[0047] In this embodiment of the application, a handwheel 621 is fixedly provided at one end of the worm gear 62 so as to facilitate manual rotation of the worm gear 62.

[0048] The length of the pull rope 51 can be adjusted by adjusting component 6, thereby adjusting the height of the handle 5 to accommodate passengers of different heights and increase its applicability.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
