Description

Walker structure improvement

The invention belongs to the technical field of a walker, in particular to a structural improvement of a walker which can reduce the use load, thereby improving the convenience of use.

According to the development of the walker, it is mainly used to help some people whose lower limbs lose some functions, such as the elderly, physical disabilities or the weak, and the part of the weight can be transferred to the walker via the upper limb by the walker. And reduce the burden on the lower body to facilitate walking. Therefore, in order to develop this kind of function, the walker is developed in response to this demand. There are many types of walking aids on the market, such as fixed type, folding type, alternating type, pulley type and rear pull type.

All kinds of walkers have different needs due to differences in structure and function design, and the present inventors want to discuss their simple fixed type walkers. The existing fixed type walkers are made up of two opposite type of feet. The frame is formed, and at least one side strut and at least one front strut are respectively disposed on the side and the front side of the bipod, so that the walker forms a dome-shaped frame that can be stood by the user in a plan view When the user uses the walking aid to assist walking, he can stand in the walking aid, and hold the ejector section of the two side legs with both hands, lift the walking aid forward, and then use the footer to the foot. After the frame is positioned on the ground, the body is forced to move forward by the force of both hands; however, since the users are old and weak, the long-term use is easy to cause the burden on both hands, and the hands are unable to exert force and the movement is inconvenient. At the same time, although it is still barely able to assist walking by the walker, it must consume more Strength, there are still inconveniences. Although the wheeled walker is designed on the market to reduce the user's mobile load, it needs to be equipped with a brake mechanism, which is not only complicated in structure, high in cost, but also needs to be constantly pressed and released by the user during use. On the contrary, it causes inconvenience in operation. What is more, when the brake mechanism is abnormal, the user cannot immediately respond, and thus the brake device cannot be used to hold the walker. Therefore, the user is prone to fall and the body is easily broken. A serious injury occurs.

In other words, the existing walker cannot meet the needs of actual use because it cannot be combined with the effect of reducing the load and being easy to operate, and the use or the load cannot be effectively moved, or the risk of the brake is abnormal. Further improvements are needed.

A structure improvement of a walker to overcome the inconvenience and trouble caused by the inability of both of them to reduce load and safety.

Therefore, the main object of the present invention is to provide a structure improvement of a walker, thereby effectively reducing the load of the mobile walker, and avoiding the problem that the vehicle cannot be effectively positioned due to the abnormality of the brake, thereby greatly improving the convenience of use and safety.

Based on the above, the present invention mainly achieves the foregoing objects and effects through the following technical means. The walker is composed of two opposite cymbal type tripods, and the tripods are formed with a ejector above. Segment, and the two ends of the jack section respectively have downwardly extending pole sections, and two opposite tripods The front edge of the leg is provided with at least one front strut, and the bottom end of each leg of the leg is respectively provided with a rolling leg set; and the rolling leg set has a cylinder, and the inner edge of the cylinder is formed with an inner ring The edge is provided for the sliding of the bead bowl seat in the cylinder body, and the ball bowl seat is provided with a ball which can protrude from the bottom surface and does not escape, and the cylinder body is provided with an elastic member on the top surface of the bead bowl.

Thereby, through the specific implementation of the above technical means, when the walking aid of the present invention is in use, when the force of the pressing and positioning is lost, the balls of the rolling foot group can automatically protrude downward to be reset, and the movement can be effectively reduced. The load of the walker, and avoiding the problem that it cannot be effectively positioned due to the abnormality of the brake, greatly improves the convenience and safety of use, thereby increasing the added value of the product and improving its economic efficiency.
