Description

Technical Field

[0001] The utility model relates to the field of assistive devices, in particular to an integrated sitting and walking assisting device with the function of assisting standing up. Background Art

[0002] The power-assisting devices commonly used by the elderly and people with weak lower limb muscle strength (hereinafter referred to as the assisted subjects) are mainly for assisting walking and assisting standing. Typical representatives of assisted walking devices are crutches and frame-type walkers, while assisted standing is generally used in household appliances such as sofas and chairs. However, when the assisted subjects go out for rehabilitation exercises or training, they need a power-assisting device that integrates the functions of assisted walking, sitting down to rest, and assisted standing.

[0003] To this end, Chinese patent CN207768631U proposes a device that combines sitting and walking assistance. This device adds a foldable seat to a wheelchair, which folds when walking and provides support with armrests, integrating functions such as assisted walking and sitting down to rest. However, it lacks an assisted standing function and is relatively large, making it difficult to assist people in carrying people on roads with steps. Separately, Chinese patent CN211884301U also proposes a walking and standing assistance device. Based on the basic structure of the wheelchair, the assisted standing function is achieved using a scissor-type telescopic frame and a telescopic push rod, while the wheelchair structure and armrests provide the functions of sitting down to rest and assisted walking. However, to ensure the strength of the scissor-type telescopic frame, this device is often made of heavy materials, resulting in high costs and low adaptability. Furthermore, the device is large, making it difficult to use in environments with steps.

[0004] In summary, there is still a lack of power-assisting devices that can simultaneously meet the functions of assisting walking, sitting down to rest, and assisting standing up, and are lightweight and low-cost. Utility Model Content

[0005] In view of this, the purpose of the present invention is to provide an integrated sitting and walking assisting device with assisted standing, so as to realize the functions of assisted walking, sitting down to rest, and assisted standing, and the device has the characteristics of simple structure, light weight and low cost.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] The foldable seat frame is connected to the support rails of the utility model and the support rails are connected to the support rails of the utility model.

[0008] Furthermore, the telescopic limit tube is composed of a square tube, a spring and two telescopic rods. The interior of the square tube is hollow, and a limit slide groove is provided in the middle section. The spring is arranged in the middle section of the square tube. A limit block is provided at one end of the telescopic rod, and the limit block is located in the limit slide groove. The other end of the telescopic rod extends from the end of the square tube.

[0009] Furthermore, the length of the telescopic limit tube is greater than the distance between the two seat mounting rods after the telescopic rod extends from the end of the square tube, and the length of the telescopic limit tube is less than the distance between the two seat mounting rods after the telescopic rod is fully retracted from the end of the square tube.

[0010] Furthermore, the power device is composed of a motor, a driving gear, a driven gear and a gear housing. The driving gear is fixedly connected to the motor output shaft, the driven gear is fixedly connected to one end of the rotating shaft, and the gear housing covers the driving gear and the driven gear.

[0011] Furthermore, the connecting member 1 is fixed by two semicircular splints connected by screws, one of the splints is provided with a mounting shaft, and both ends of the rotating shaft are rotatably connected to the mounting shaft of the connecting member 1; the connecting member 2 is formed by two cylindrical sections stacked vertically up and down and welded, the bottom cylinder is sleeved on the end of the seat mounting rod, and the rear support rod is rotatably connected to the top cylinder of the connecting member 2 through a bearing; the connecting member 3 is connected by two fastening plates by screws, one end of the fastening plate is a rectangular groove, which is sleeved on the telescopic limit tube, and the other end is a circular groove, which is sleeved on the front support rod.

[0012] Furthermore, the flexible cloth is made of cotton cloth or Oxford cloth.

[0013] The beneficial effects of the present invention are:

[0014] (1) The power device drives the rotating shaft to tighten the Oxford cloth, exerting an oblique upward force on the auxiliary object, while achieving auxiliary standing, simplifying the standing structure and reducing the weight of the equipment.

[0015] (2) An auxiliary walking frame is formed by combining two inverted U-shaped handrail brackets with a stabilizer bar. It has the characteristics of simple structure, small size and light weight, which is conducive to the assisted object walking in different environments and has good passability.

[0016] (3) The telescopic limit tube and the rear support rod connected in rotation, in conjunction with the power device and Oxford cloth, can automatically fold the seat completely after the assisted standing is achieved, freeing up the leg space for the assisted person to move, achieving the characteristic of barrier-free assisted walking.

DETAILED DESCRIPTION

[0024] The following is a detailed description of the implementation of the technical solution of the present invention in conjunction with the accompanying drawings. It should be noted that the front and rear mentioned in the text are based on the auxiliary object sitting on the power-assisting device, with the facing side being the front and the back side being the rear.

[0025] like Figure 1 、 2As shown in Figures 3 and 6, an integrated sitting and walking assist device with assisted standing up includes an assisted walking frame, a bench and an assisted standing up assembly. The assisted walking frame is formed by welding two inverted U-shaped armrest brackets 1 through a stabilizer bar 2, and the middle sections of the two armrest brackets 1 are fixedly connected to a bench mounting rod 3. The assisted walking frame of this structure has a simple structure and there is no risk of slipping when going up and down slopes. A connector 1 4 is fixedly connected to the upper part of the armrest bracket 1, and a connector 2 5 is fixedly connected to the rear end of the bench mounting rod 3. The bench consists of a bench surface 6, a front support rod 7, a rear support rod 8 and a telescopic limit tube 9. The bench surface 6 is fixed on the front support rod 7 and the rear support rod 8 arranged in parallel, and both ends of the rear support rod 8 are rotatably connected to the connector 2 5. The front support rod 7 is freely placed on the bench mounting rod 3; the telescopic limit tube 9 is arranged below the front support rod 7 and is fixedly connected to the front support rod 7 via the connector 3 15; the auxiliary standing assembly consists of a flexible cloth 10, a rotating shaft 11, and a power device. The flexible cloth 10 is placed above the bench surface 6, and its two ends are respectively fixedly connected to the rotating shaft 11 and the telescopic limit tube 9; the two ends of the rotating shaft 11 are rotatably connected to the connector 1 4. The power device is arranged at one end of the rotating shaft 11. The power device can drive the rotating shaft 11 to rotate, causing the flexible cloth 10 to be rolled up on the rotating shaft 11 and shrink, thereby providing an oblique upward force for the assisted object to achieve assisted standing. The flexible cloth 10 can be made of cotton cloth or Oxford cloth; this auxiliary standing method avoids the strict requirements on the material of the mechanism when using a scissor-type telescopic frame or similar linkage mechanism to achieve assisted standing, greatly reducing the cost and weight of the device.

[0026] like Figure 2 、 5 As shown, the telescopic stopper tube 9 consists of a square tube 901, a spring 902, and two telescopic rods 903. The square tube 901 is hollow and has a stopper slot 904 in its middle. The spring 902 is located in the middle of the square tube 901. A stopper is located at one end of the telescopic rod 903, which is positioned within the stopper slot 904. The other end of the telescopic rod 903 extends from the end of the square tube 901. After the telescopic rod 903 extends from the end of the square tube 901, the length of the telescopic stopper tube 9 is greater than the distance between the two seat mounting rods 3. This prevents the seat from folding when the power unit drives the rotating shaft 11 to retract the flexible fabric 10. After the telescopic rod 903 is fully retracted from the end of the square tube 901, the length of the telescopic stopper tube 9 is less than the distance between the two seat mounting rods 3. When the person standing up, the telescopic rod 903 retracts, and the power unit drives the rotating shaft 11 to continue retracting the flexible fabric 10, causing the seat to fold and stand upright, freeing up space for the person's legs to move while walking.

[0027] like Figure 3 As shown, the power device consists of a motor 12, a driving gear 13, a driven gear 14 and a gear housing. The driving gear 13 is fixedly connected to the output shaft of the motor 12, and the driven gear 14 is fixedly connected to one end of the rotating shaft 11. The gear housing covers the driving gear 13 and the driven gear 14 to prevent the limbs of the assisted object from being stuck in the gears.

[0028] like Figure 1 、 4 As shown in , 6, the connecting piece 4 is fixed by two semicircular splints connected by screws, one of the splints is provided with a mounting shaft, and the two ends of the rotating shaft 11 are rotatably connected to the mounting shaft of the connecting piece 4; the connecting piece 2 5 is formed by two cylindrical sections stacked vertically up and down and welded, the bottom cylinder is sleeved on the end of the bench mounting rod 3, and the rear support rod 8 is rotatably connected to the top cylinder of the connecting piece 2 5; the connecting piece 3 15 is connected by two fastening plates by screws, one end of the fastening plate is a rectangular groove, which is sleeved on the telescopic limit tube 9, and the other end is a circular groove, which is sleeved on the front support rod 7.

[0029] When the utility model assists standing up, the motor 12 drives the driving gear 13 and the driven gear 14, and then drives the rotating shaft 11 to rotate, so that the flexible cloth 10 fixed on the rotating shaft 11 is rolled on the rotating shaft 11 and gradually tightened. Figure 2 As shown, an oblique upward force is applied to the assisted person to achieve assisted standing. When assisting walking, the telescopic limit tube is retracted, allowing the seat to rotate around the rear support rod 8. Then, the power device drives the flexible cloth 10 to continue to retract. The other end of the flexible cloth 10 is fixed to the telescopic limit tube of the seat. The seat flips up under the pulling force of the retracted flexible cloth 10. Finally, the assisted person can hold the armrest bracket 1 with both hands and move forward.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
