Description

Technical Field

[0001] The utility model belongs to the technical field of preventing the elderly from falling, and specifically relates to a device for preventing the elderly from falling at home. Background Art

[0002] The prior art discloses an anti-fall device for the elderly (CN202320493184.4), comprising a front bracket, a plurality of connecting rods fixedly connected to the rear end of the front bracket, and a rear bracket fixedly connected to the rear end of the plurality of connecting rods. Both the front bracket and the rear bracket are U-shaped structures, a front handrail fixedly connected to the upper end of the front bracket, a rear handrail fixedly connected to the upper end of the rear bracket, and a protective device fixedly connected to the right end of the rear bracket. Two No. 1 upper support rods and two No. 1 lower support rods are arranged on the front bracket, and two No. 2 upper support rods and two No. 2 lower support rods are arranged on the rear bracket.

[0003] After searching, it was found that the overall range of activity of the device is relatively single. When faced with a relatively small range of activities at home, it is impossible to move and change position effectively. It is not flexible enough and the user experience for the elderly is not comfortable enough. In addition, since the height adjustment or the use of armrests of the device does not take into account the suitability of taller elderly people, there are many limitations on the applicable population. Furthermore, the use of wheels essentially has no obvious effect on preventing falls, and does not take into account that the elderly cannot effectively control the direction of movement of the wheels or limit the movement of the wheels due to weak muscle strength, poor balance and coordination. This makes it easy for the wheels to slip due to external force or other reasons, causing the elderly to fall.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0027] A fall prevention device for elderly people at home, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes an upper bracket 10, which is fixedly connected to a lower bracket 14 and a middle bracket 15. A sliding assembly for changing the position is arranged inside the upper bracket 10, and the sliding assembly includes a belt waist 16, a slider 18 and a blocking plate 19. The belt waist 16 is fixedly connected to the slider 18, and the slider 18 is slidably connected to the upper bracket 10 and the blocking plate 19 and elastically connected to the upper bracket 10. The blocking plate 19 is fixedly connected to the inner wall surface of the upper bracket 10; as shown Figure 3 As shown, a slide groove 17 is provided inside the upper bracket 10, one side of the slide block 18 is a trapezoidal slide block, and the other side is a square block, the blocking plate 19 is two opposite L-shaped blocks, and a square slideway is formed between the two opposite L-shaped blocks. The size of the square block is smaller than or equal to the square slideway between the blocking plates 19, and the slide block 18 slides on the slide groove 17 and the square slideway; Figure 3 As shown, the opposite side of the arc groove of the upper bracket 10 and the side of the slider 18 adjacent to the square block are both fixedly connected with a telescopic spring 20 , and the slider 18 is elastically connected to the upper bracket 10 via the telescopic spring 20 .

[0028] The working principle is as follows. When using the device, since the elderly have a small space for activities at home and it is relatively inconvenient, the movement of the direction and position also needs to be considered when using the anti-fall device. Therefore, the slider 18 is moved on the slide groove 17 to achieve horizontal movement, and the square slide of the blocking plate 19 is used to limit the slider 18. However, due to the inconvenience of the elderly's movement, in order to increase the flexibility of the device, the elastic force of the telescopic spring 20 is used to pull it back, thereby ensuring the flexibility of the overall sliding assembly. The belt waist 16 connected to the slider 18 can effectively control the movement of the elderly, and the restraining force of the belt can also effectively ensure the balance of the elderly's body. The softer material can also make the elderly have a more comfortable experience when using it.

[0029] like Figure 1 and Figure 5 As shown, a stretching assembly for stretching the support height is provided on the middle bracket 15, and the stretching assembly includes a handrail rod 26, a resistance block 28, a slide bar 29 and a handrail 30. The handrail rod 26 is fixed on the top of the middle bracket 15, the resistance block 28 is fixedly connected to the bottom of the slide bar 29 and elastically connected to the middle bracket 15, and the slide bar 29 is fixedly connected to the handrail 30 and slidably connected in the handrail rod 26, and is limited by the resistance block 28; Figure 1 and Figure 5 As shown, the handrail rod 26 is a square thin-walled structure, the internal size of which is smaller than or equal to the size of the resistance block 28, and the top is provided with a hole whose size is equal to the size of the slide bar 29 and smaller than the size of the resistance block 28, and the bottom of the resistance block 28 and the top of the middle bracket 15 are welded with the same tension spring 27, and the slide bar 29 is elastically connected to the middle bracket 15 through the tension spring 27.

[0030] The working principle is as follows. Most elderly people have hunched bodies. Therefore, in order to make the use of the support more comfortable for such elderly people, a middle bracket 15 is added between the upper and lower brackets, and a stretching component with adjustable height is provided. The component uses a stretching armrest 30 to drive the sliding rod 29 to slide in the armrest rod 26, so that the stretching spring 27 is pulled; the size of the blocking block 28 is used to limit the position. This design is mainly used to deal with two situations. The first is that after the elderly sit down, they need to stand up because they are at home and their children may not be there. At this time, if there is no one to help them, they may not be able to stand up. Some elderly people are taller. To deal with this situation, they can stand up by pressing the armrest 30. Another situation is to choose to use a stretching component that can be stretched to ensure the stability of the body when they need support when standing. This situation mainly deals with the elderly population with taller heights, so that the applicability of the device is further enhanced, thereby expanding the range of people who can use it.

[0031] like Figure 2 and Figure 4 As shown, a blocking assembly for controlling the moving speed is provided at the bottom of the lower bracket 14, and the blocking assembly includes a sliding wheel 22, a rack block 23 and a gear 24. The sliding wheel 22 is rotatably connected to the lower bracket 14, the rack block 23 is fixedly connected to the bottom of the lower bracket 14, and the gear 24 is fixedly connected to the sliding wheel 22 and is transmission-connected to the rack block 23; Figure 1 and Figure 2 As shown, the interior of the upper bracket 10 is arc-shaped and an arc groove is provided in the reverse direction of the top of the interior thereof, and a backrest 11 is clamped thereon, a support seat plate 12 is fixedly connected to the bottom of the backrest 11, support legs 13 are welded on both sides of the support seat plate 12, and the support legs 13 are fixedly connected to the lower bracket 14, and a middle bracket 15 is welded on one side of the two support legs 13, and the bottom of one side of the lower bracket 14 is square, and a placement groove 25 is provided therein; as shown Figure 2 and Figure 4 As shown, a hinge seat 21 is fixedly connected to the bottom of the lower bracket 14, and a shaft column for rotation is arranged inside the hinge seat 21, and the sliding wheel 22 is rotatably connected to the hinge seat 21 through the shaft column.

[0032] The working principle is as follows: the elderly may be unable to walk sometimes and need to rest or exercise because of their weak muscles and poor balance and coordination. The device is provided with a backrest 11 for rest and a support seat plate 12 on one side, which is fixed to the lower bracket 14 by the support legs 13. It can be moved with the device and used according to the needs of the elderly. In addition, since the elderly have weak muscles and cannot effectively control the direction of movement of the wheels, a suction cup is provided at the bottom of the lower bracket 14, which can enable the device to adhere to the ground when it is on a smooth ground such as tiles, thereby ensuring the stability of the device and the elderly. In addition, when the ground is not smooth, since the meshing between gears is also affected by the gear speed, the sliding wheel 22 fixed by the gear rotates in the hinge seat 21, and the moving speed is controlled by the meshing rack block 23. This can effectively avoid safety problems caused by wheel slippage, so that the device and the elderly using it can be more secure and more effectively avoid falling.
