Portable sit-to-stand walker

Abstract

The portable sitting walker mainly comprises front and rear vertical rods with a pair of casters under the bottom, which are connected with upper and lower cross beams through supporting sleeves and hinges to form a quadrilateral structure. A handle tube and a handle are mounted on the upper end of the front vertical rod to provide continuous support force for the user when he pushes the walker with the handle. A saddle is mounted on the upper end of the rear vertical rod, so that the user can ride and rest. Shock absorbers and flexible supporting bridges are arranged above the casters to reduce the transmission of vibration to the handle. The walker has small volume, light weight and can be carried by one hand. It can adapt to various ground surfaces and can smoothly pass through entrances and exits of various places and their corridors.

Description

Technical Field

[0001] This utility model relates to walking aids for middle-aged and elderly people, especially lightweight and portable walking aids. Background Technology

[0002] There are two main types of walking aids currently available: one for the general population and the other for people undergoing rehabilitation. Both consist of a three-dimensional frame structure made up of several horizontal and vertical support rods, equipped with four sets of casters, two sets of casters plus two legs, or four legs. They are generally heavy and bulky. Some, although foldable, still take up a lot of space, making them inconvenient to carry on buses or subways, or in entrances to train stations or scenic spots. Others are lighter and smaller when folded, but lack comfort and maneuverability. Summary of the Invention

[0003] In order to overcome the shortcomings of existing technologies, such as large size and weight, inconvenience of carrying, and poor passage in narrow and winding spaces, this utility model provides a lightweight and portable seated walking aid that can be easily taken on buses and smoothly passed through the entrances and exits of stations and scenic spots.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a quadrilateral planar frame is used as the supporting structure. The left and right sides of the quadrilateral structure serve as the front and rear uprights of the walker, extending upwards and downwards. A pair of casters are fixed to the lower end of each upright. Two support sleeves are fitted onto the top of the cylindrical front upright, with a clearance fit between the support sleeves and the upright, and are limited and supported on the upright by retaining rings. The upper and lower sides of the quadrilateral structure serve as the upper and lower crossbeams of the walker. The upper support sleeve is fixedly connected to the upper crossbeam, and the lower support sleeve is hinged to the lower crossbeam. The other end of each crossbeam is hinged to the rear upright. The upper end of the front upright is fixed with the walker handle, and the upper end of the rear upright is fixed with the saddle. When the user holds the handle and walks forward, the walker moves at the same speed. To turn left or right, the user turns the handle, and the front upright and the casters at the lower end turn synchronously, causing the walker to turn left or right accordingly. The user can also sit and rest on the saddle.

[0005] The advantages of this utility model are: fewer components, smaller size, lighter weight, and easier to move. It solves the problems of existing walking aids being inconvenient to carry and difficult to pass through narrow or complex-shaped passages. In addition to providing continuous follow-up support on one side of the user's body while walking, it can also be used to sit and rest when not walking. Attached Figure Description

[0011] The upper support sleeve (5) is fitted onto the upper part of the cylindrical front upright (7). Snap rings 1 (4), 2 (6), and 3 (10) are fixed to the front upright (7). Snap rings 1 (4) and 2 (6) limit the upper support sleeve (5). The upper support sleeve (5) is fixed to the front end of the upper crossbeam (21). The upper hinge (19) hinges the rear end of the upper crossbeam (21) to the upper part of the rear upright (18). The lower support sleeve (9) is fitted onto the lower part of the front upright (7), preventing it from sliding down via snap ring 3 (10). The lower front hinge (8) connects the lower support sleeve (9) to the front end of the lower crossbeam (14), and the lower rear hinge (15) connects the rear end of the lower crossbeam (41) to the lower part of the rear upright (18). The upper end of the front upright (7) is fitted with a handle tube (2), which is pinned by a spring pin (3). The handle tube (2)... The front upright (7) has a handle (1); the lower end of the front upright (7) is connected to the shock absorber (11), the upper part of the shock absorber spring (11-1) and the spindle (11-2) is fixed to the front upright (7), the lower part of the shock absorber spring (11-1) is fixed to the moving tube (11-3), the lower end of the moving tube (11-3) is fixed to the front wheel axle (12), and the front wheel (13) is installed at both ends of the front wheel axle (12); the upper end of the rear upright (18) is equipped with a saddle (20), the lower end is fixed to the support bridge (22), the support bridge (22) is embedded with a flexible buffer layer, so that the rear wheel axle (16) and the support bridge (22) are flexibly connected, and the rear wheel (17) is installed at both ends of the rear wheel axle (16). The front upright (7) is fitted with the upper support sleeve (5) and the lower support sleeve (9) with clearance, so it can rotate freely in 360 degrees. The user holds the handle (1) and pushes the walker forward. Turning the handle (1) will turn the walker accordingly. The shock absorber (11) and the support bridge (22) can improve the applicability and comfort of the walker.
