Convertible crutches

Abstract

The invention relates to a deformable crutch, comprising a telescopically adjustable rod, a handle on the upper end of the rod, and a deformed support mechanism at the lower end of the rod. To the evenly distributed support foot assembly, the movable ring can be axially slidably sleeved on the pole, and the lower fixed seat is fixed on the bottom end of the pole. Push-pull sleeve, the manual push-pull sleeve can slide axially along the rod rod and can be locked on the rod rod, the support leg includes a connecting arm, one end of the connecting arm is hinged on the movable ring, and the other end of the connecting arm extends The ground-contacting feet arranged at an obtuse angle, the grounding feet are vertical to the ground after the support legs are opened, and the ground-contacting feet are provided with rubber pads, one end of the connecting rod is hinged on the lower fixed seat, and the other end of the connecting rod is hinged to the connection of the support leg middle of arm. It has the advantages of simple structure, light weight and convenient operation.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to crutches, in particular to a deformable crutch that can realize the transformation of single-leg support and four-leg support. Background technique [0002] With the intensification of the aging of the population, the number of the elderly population has climbed, and the elderly group must be paid more attention. With the increase of age, the physiological function of the elderly gradually declines, and the physical ability declines significantly. Crutches are widely used as a simple device to assist walking. The traditional crutches are supported by one leg and multiple legs (usually four legs). The crutches supported by one leg are light to carry, but have insufficient stability. The crutches supported by four legs have good support but are inconvenient to carry. [0003] In order to solve the defects of single-legged crutches and four-legged crutches and facilitate...

AI Technical Summary

Problems solved by technology

Under the structural design of the crutch, there is a large volume of the fixed seat, and the electric drive is used, and the mechanism is complicated, so that the overall weight of the crutch is large, which is not conducive to carrying and using; and due to the electric drive, it is necessary to ensure that the crutch can be supported when it is supported by four legs. The stability, the locking after the four legs are opened is more critical, and the self-locking function of the electric drive mechanism itself cannot be realized well, so most of them need to be specially set for the locking mechanism, and the electronic devices need to be dustproof and waterproof. etc., so the electric drive structure complicates the crutch structure and makes it impossible to achieve portability; while most of the current market is electric design, there are few variable crutches with simple design that are convenient for manual operation
