Description

folding crutches

technical field

The invention relates to the technical field of crutches, in particular to a folding crutch.

Background technique

Conventional crutches generally have different types such as a cane that can be held by the hand, a forearm crutch or an underarm crutch that can support the armpit. ', a connecting frame 2', a back cushion 3', a grip 4', a soft cover body 11' that can be grounded under the support rod 1', and the connecting frame 2' has two rod bodies 21', two The lower part of the rod body 21' is fixedly connected with the support rod 1', the upper part is engaged with the cushion 3', and the center is engaged with the handle 4', so that when the user's armpit is placed on the cushion 3', the palm can hold the handle 4' and make the support rod 1' The lower sleeve body 11' can be grounded to form a support point.

However, the aforementioned underarm crutches have the following deficiencies:

1. The armpit crutches must have a large length from the armpit to the ground. When not in use, it is inconvenient to store and carry in the car.

2. The soft cover body 11' below the support rod 1' has poor shock absorption effect, resulting in discomfort and lack of walking with the crutch.

3. The combined height of the cushion 3' and the handle 4' is not easy to adjust and cannot be used for different users.

4. The crutches must be stably clamped by the armpits to the cushion 3' or the hand to hold the handle 4' to prevent the crutches from being separated from the human body, which may still cause the crutches to break away.

In order to improve the above-mentioned lack of crutches such as Taiwan TWM266902, a separable upper and lower rod group is designed. The upper and lower rod groups are respectively provided with a jacket and an insertion rod, and a ring buckle that can rotate and tighten the outer jacket is also provided, so that the insertion rod can be disengaged. The outer cover enables the upper and lower rod groups to be separated and folded, and the insertion rod can be inserted into the outer jacket and then tighten the loop to make the upper and lower rod groups stably combined. , and when the buckle is not tightened, it may still cause the upper and lower rod groups to become loose or detached, and when the upper and lower rod groups are separated, the upper and lower rod groups cannot be stably connected, resulting in poor folding integrity.

Another example is the crutch of Taiwan TWM442139, which is provided with a telescopic spring on the lower support rod body so that the crutch can have better cushioning elasticity. However, the additional spring will increase the cost of components and assembly. Another example is the U.S. US20100206348 case. The crutches are provided with hook-shaped elastic feet below, The elastic comfort can be improved by the elastic feet. However, if the elastic feet are subjected to large pressure, it may cause excessive bending, which may cause the length of the crutches to change significantly, which is unsafe. Moreover, if the elastic feet are provided with a harder material, the pressure deformation can be reduced. When the temperature is too high, it will cause the loss of cushioning comfort.
