Problems solved by technology

However, in actual use, this kind of stable crutch has defects; for people whose center of gravity is seriously unstable, when they use crutches, the inclination of the crutches is usually very large. At this time, the legs 3 below the connecting plate 2 The number of actual landings is only 1 or 2. In this case, the frictional resistance between the crutches and the ground does not increase significantly. What is more serious is that the force of the human body acting on the crutches falls to the ground along the support rod 1. It can be seen that the stability of this kind of crutch is seriously insufficient when it is used at an obvious inclination.

Embodiment 1

[0022] figure 1 Shown is the first embodiment of the high-stable crutch, wherein the high-stable crutch includes a support rod 1, the upper end of the support rod 1 is provided with a handle (not shown), and the lower end is provided with a rectangular connecting plate 2; Below the connecting plate 2 are fixed 4 legs 3 surrounding a square, and each leg 3 is wrapped with a non-slip rubber sleeve 31; the support rod 1 and the connecting plate 2 are movably connected through a ball connecting pair 12 .

[0023] In addition, considering that in an accidental situation, the ball joint 12 may be dislocated. At this time, the support rod 1 may slip off the plane where the connecting plate 2 is located, causing a fall accident. 2. A layer of flexible rubber layer (simple structure, not shown) is arranged on the top. The thickness of the flexible rubber layer is 5mm~10mm. , a depression can be placed on the surface of the flexible rubber layer, and the support rod 1 is sunk into the...

Embodiment 2

[0025] figure 2 Shown is the second embodiment of the high-stable crutches. On the basis of the first embodiment, a constraining ring 120 is added around the connecting plate 2 and the ball connecting pair 12 to constrain the support The inclination of the rod 1 prevents it from being excessively inclined; generally, the angle constraint between the support rod 1 and the vertical direction can be changed between 0° and 45°. At this time, according to the geometric relationship, it is only necessary to make the The ratio of the height of the restriction ring 120 to the inner radius of the restriction ring 120 is 1:1.

[0026] Embodiment two:

[0027] image 3 Shown is the third embodiment of the high-stable crutches, which is different from the first embodiment in that: the connecting plate 2 is in the form of a round-headed triangle, and three legs 3 enclosing an equilateral triangle are fixed below it, and each leg 3 is Cover with anti-skid rubber cover 31.

Abstract

The invention provides a high-stability crutch, which comprises a support rod, wherein the upper end of the support rod is provided with a handle, the lower end of the support rod is provided with a connecting plate, three to four support feet forming a polygon in a surrounding manner are fixedly arranged under the connecting plate, an anti-slip rubber sleeve is covered on each support foot, and the support rod and the connecting plate are movably connected through a ball connecting pair. The high-stability crutch can maintain high stability in various use states.

Description

[0001] technical field [0002] The invention relates to the field of daily necessities, in particular to a crutch. [0003] Background technique [0004] Crutches are commonly used walking aids for the elderly or other people with inconvenient legs and feet. They can effectively support the human body, prevent the human body from falling due to unstable center of gravity, and save energy. [0005] The main part of the traditional crutch is a support rod, the lower end of which is usually provided with a non-slip rubber sleeve, and the upper end of the support rod is a handle. For this kind of crutches, it is suitable for ordinary people with inconvenient legs and feet. For the elderly with heavy weight, or people who are seriously weak and have unstable center of gravity, the area of ​​contact between the lower end of the support rod and the ground is very small. Landing on an incline, it is easy to slip and cause the user to fall. [0006] In view of the above-mentioned...
