Abstract

The invention discloses an anti-fall walking crutch for the elderly, which comprises a main rod and at least six side rods evenly distributed along the main rod. The upper end of the main rod is fixedly provided with a handle. The lower end of the rod is provided with a roller, a first spring is provided between each side rod and the main rod, and a limit rocker mechanism is set between each side rod and the main rod to limit the rotation angle of the side rod, adjacent ones. A second spring is arranged between the two side bars; the advantage is that when the old man uses the crutch and the center of gravity is unstable and falls to one side (mainly the front side or the left and right sides), the side bar on the corresponding side It is stretched by sliding under force, which supports the main rod, and because a second spring is arranged between the two adjacent side rods, the stretched side rod will pull the two adjacent side rods to jointly support the main rod. The rod makes the support of the main rod more stable, so as to provide a better support effect for the elderly and prevent the elderly from falling and being injured.

Description

A kind of anti-fall walking cane for the elderly

technical field

The invention relates to a crutch for walking, in particular to an anti-fall walking crutch for the elderly.

Background technique

China is in the stage of rapid development of population aging. As the age of the elderly increases, frailty, sickness and difficulty in moving are common phenomena. For the elderly, crutches can be used to stand up, lean on, and walk. It is a good travel helper. For the elderly who can walk alone with healthy hands and feet, but are more difficult, the crutches currently available on the market are relatively simple, and they are basically simple straight-bar crutches. It cannot support the elderly.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to provide an anti-falling walking stick for the elderly, which can provide support when the center of gravity of the elderly is unstable and is about to fall, and greatly reduces the risk of falling for the elderly.

The technical solution adopted by the present invention to solve the above technical problems is: an anti-fall walking cane for the elderly, comprising a main rod and at least six side rods evenly distributed along the main rod, the upper end of the main rod is fixedly provided with a handle, so The upper end of the side rod is hinged with the main rod, the lower end of the side rod is provided with a roller, and a first spring is provided between each of the side rods and the main rod, and each of the side rods is provided with a first spring. A limit rocker mechanism is arranged between the side bar and the main bar to limit the rotation angle of the side bar, and a second spring is arranged between two adjacent side bars.

Further, the limit rocker mechanism includes a first connecting rod and a second connecting rod, a first hinge seat is fixedly arranged on the main rod, and one end of the first connecting rod is connected to the first connecting rod. A hinge seat is hinged, the other end of the first link is hinged with one end of the second link, and the other end of the second link is hinged with the side rod.

Further, an anti-jamming mechanism is arranged between the first connecting rod and the second connecting rod.

Further, the anti-jamming mechanism is integrally provided with a limit bump on one end of the second connecting rod. When the limit bump touches on the first connecting rod, The angle between the first connecting rod and the second connecting rod is less than 180°, so as to prevent the first connecting rod and the second connecting rod from being stuck when they are pulled apart. Collapse to reset.

Further, the lower end of the main rod is fixedly provided with a non-slip sleeve.

Further, a second hinge seat is fixed on the main rod, and the upper end of the side rod is hinged with the second hinge seat.

Further, the handle is provided with a flashlight.

Further, the main rod is a telescopic rod, and a locking mechanism is provided on the telescopic rod.

Compared with the prior art, the advantage of the present invention is that a first spring is arranged between each side rod and the main rod, and a limit rocker mechanism is set between each side rod and the main rod, when the elderly are using the When the center of gravity of the crutches is unstable and falls to one side (mainly the front side or the left and right sides), the side bar on the corresponding side is forced to slide and is stretched, which supports the main bar, and because of the adjacent A second spring is arranged between the two side rods, and the stretched side rod will pull the adjacent two side rods to support the main rod together, so that the support of the main rod is more stable, thereby providing better support for the elderly It can prevent the elderly from falling and being injured; and when the crutches fall in different directions, the side bars on the corresponding side slide flexibly, and the support for the main rod is stable and reliable; in addition, when not in use, the crutches can also be kept upright, which is convenient for the elderly take.

Detailed ways

The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

As shown in the figure, an anti-fall walking cane for the elderly includes a main rod 1 and six side rods 2 evenly distributed along the main rod. The upper end of the main rod 1 is fixedly provided with a handle 3, and the main rod 1 is fixedly provided with a second The hinge seat 11, the upper end of the side rod 2 is hinged with the second hinge seat 11, the lower end of the side rod 2 is provided with a roller 4, and a first spring 5 is provided between each side rod 2 and the main rod 1, and each side rod 2 is provided with a first spring 5. A limit rocker mechanism is arranged between the rod 2 and the main rod 1 to limit the rotation angle of the side rod 2. The limit rocker mechanism includes a first link 6 and a second link 7, and the main rod 1 is fixedly provided with a first link. A hinge seat 12, one end of the first link 6 is hinged with the first hinge seat 12, the other end of the first link 6 is hinged with one end of the second link 7, and the other end of the second link 7 is hinged with the side The rods 2 are hinged, and one end of the second connecting rod 7 is integrally provided with a limiting bump 71. When the limiting bump 71 abuts on the first connecting rod 6, the space between the first connecting rod 6 and the second connecting rod 7 The included angle α is less than 180° to prevent the first connecting rod 6 and the second connecting rod 7 from being stuck and unable to close and reset when they are pulled apart.
