Roller skating type sitting hand crutch

Abstract

The invention provides a roller skating type sitting hand crutch. The roller skating type sitting hand crutch comprises a hand crutch rod, a seat face, a telescopic extension mechanism, a telescopic rod, a bottom stabilizing support and a retainer, the hand crutch rod is located above the seat face, and the hand crutch rod is detachably connected with the seat face; the top of the telescopic rod is detachably connected with the seat face, the bottom of the telescopic rod penetrates through the bottom stabilizing support and then is connected with the retainer, and when force is applied downwards, the retainer makes contact with the ground; the telescopic extension mechanism comprises a plurality of transverse strips, a plurality of supporting rods correspondingly hinged to the transverse strips and a movable part, the free ends of the transverse strips are hinged to the seat face, the free ends of the supporting rods are hinged to the movable part, the movable part is arranged on the telescopic rod in a sliding mode, and when the transverse strips extend under the action of the movable part to form a seat face extension face, the movable part is fixed on the telescopic rod; and pulleys are arranged on the bottom stabilizing support. The roller skating type sitting hand crutch can be transformed into a chair while having the function of the hand crutch, switching of two modes of the crutch and the chair is achieved, and stability and safety are higher.

Description

technical field [0001] The invention belongs to the field of assistive technologies for the elderly or disabled, and in particular relates to a wheel-skating walkable hand crutch. Background technique [0002] Crutches are an important medical rehabilitation aid. There are generally four types of crutches on the market: standard hand crutches, four-legged crutches, standard walkers and four-wheel walkers. Such as figure 1 As shown, the standard hand crutch has a single function, and the main load-bearing structure needs to achieve considerable hardness and weak stability; figure 2 As shown, the stability of the four-legged crutch is improved, but when the hardness of the crutch reaches a certain level, the weight will also increase, and part of the physical strength of the elderly will be consumed between the ups and downs, which increases the walking burden of the elderly; image 3 As shown, the double-grip and four-legged structure of the standard walker greatly enhance...

AI Technical Summary

Problems solved by technology

like figure 1 As shown, the standard hand crutch has a single function, and the main load-bearing structure needs to achieve considerable hardness and weak stability; figure 2 As shown, the stability of the four-legged crutch is improved, but when the hardness of the crutch reaches a certain level, the weight will also increase, and part of the physical strength of the elderly will be consumed between the ups and downs, which increases the walking burden of the elderly; image 3 As shown, the double-grip and four-legged structure of the standard walker greatly enhances the stability of the crutches. Multiple fulcrums can also improve the safety and reliability of the crutches and keep the user's body balanced to prevent falls. However, the increase in material will also increase the weight of the crutch itself, so that the user needs to spend more force on lifting; Figure 4 As shown, the four-wheeled walker is equipped with wheels. The use of the wheels allows the heavy structure of the walker to move smoothly and effortlessly. However, since the wheels can be turned at will, the stability of the crutches will decrease, which will greatly increase the risk of falling.
