Technical field of wheeled walker with variable wheelchair

[0001] The present utility model relates to a walker specially designed for the elderly, people with limited mobility or the disabled, and is specifically a wheeled walker with a variable wheelchair.

Background technique

[0002] A wheeled walker is also called a walker. It is well known that its basic structure is combined with a walker frame, which can usually be adjusted in height to adapt to users of different heights, and wheels are installed for users to promote. Roller walkers or wheeled walkers are widely used by the elderly and/or other people who have difficulty walking without the aid of walkers. However, traditional wheeled walkers do not have the ability to transport when the user sits down. A special foot support component required to support the user's foot. The utility model of the authorized announcement number CN 201019980Y discloses a walking device for assisting individuals to move and can be temporarily converted into a wheeled transport chair. It includes a frame structure including two front legs and a rotatable wheel supported on it. On the two hind legs. The seat is connected to the frame structure. The backrest is selectively set in the front position for the case of sitting backwards, or set in the rear position for the case of sitting forwards. The footrest assembly is selectively connected to the frame structure and is adapted to pivot between the folded position and the unfolded position about a first pivot axis and a second pivot axis that are parallel to each other. The utility model can be modified and temporarily converted into a wheeled transport chair. However, the utility model does not have a folding function. Due to its large size, it is inconvenient to carry and transport.

Summary of the invention

Detailed ways

[0022] The specific implementation of the utility model will be further described below in conjunction with the accompanying drawings:

[0023] As shown in FIGS. 1 and 2, a wheeled walker for a variable wheelchair includes a base 3 formed by a frame 1, left and right seat tubes 13 fixed on the left and right frame tubes 2. The two seven-shaped frames 4 connected to the front leg tube 10 located at the middle and lower part of the side frame tube 2 and the foot pedal 5 connected at one end of the seven-shaped frame 4, and the rear wheel connected to the rear part of the frame 1 through the connecting piece 6. The side frame vertical tube 17 is inserted into the side frame tube 2 through the middle sleeve 18, and the middle sleeve 18 has a tightening screw 19, and the height of the side frame vertical pipe 17 can be adjusted by the screw 19. The upper part of the side frame upright pipe 17 is bent into a handle, the handle is provided with a non-slip handle cover 20, and a brake handle 2L is provided under the handle. A backrest 7 is installed between the left and right frame upright pipes 17, which is a further step of the utility model. Optimized, the backrest 7 is composed of two backing plates 8 respectively installed on the left and right upright pipes 17 and an elastic band 9 connecting the two backing plates 8. Because the elastic band 9 is elastic, the backing plate 8 can be installed on the side frame upright The inside or outside of the tube 17, in this embodiment, when the utility model is used as a walking aid, the backing plate 8 is installed on the inner side of the side frame upright tube 17 to form the support of the walking aid (Figure 4) . When the utility model is used as a wheelchair, the backing plate 8 is installed on the outer side of the side frame upright pipe 17 to form the backrest of the wheelchair.

[0024] Referring again to FIGS. 1, 2 and 3, the lower end of the side frame tube 2 is connected to the side frame front tube 22 and the side frame rear elbow tube 25, and the two ends of the front leg tube 10 are respectively fixed to the side frame tube 2 and the side frame. On the front tube 22, one end of the seven-shaped frame 4 is installed on the front leg tube 10 through two parallel movable feet 23, and the other end is connected to the foot pedal 5 through a rotatable shaft, and the foot pedal 5 can rotate around the rotatable shaft. Rotate from a horizontal position to a vertical position, or rotate the foot pedal 5 to a horizontal position. With the above-mentioned structure, the effect of the foot board 5 turning over is formed. When the utility model is used as a wheelchair, the footrest 5 is installed on the forefoot tube 10 through the movable tripod 23, and the seater's feet can be placed on the footrest 5. Secondly, the footrest 5 can also be made Can increase surface roughness

Rough ripples or grooves, etc., make it convenient for the occupant's feet to be placed on the pedal 5 (as shown in Figure 1 and Figure 2); when the utility model is used as a walking aid, the activity can be removed by using a tool The tripod 23 is sufficient (as shown in Figure 4). Two front wheels 24 are installed at the front end of the side frame front tube 22, one end of the side frame rear elbow tube 25 is connected to the side frame tube 2 through a connecting piece 6, and the other end is installed with a rear wheel 26.

[0025] As shown in FIG. 6, the money connector enables the rear elbow 25 of the side frame to reach a rotation of 0-120 degrees. In this embodiment, a protruding screw hole 27 is formed on the bottom surface of the side frame rear bend tube 25, and a locking handle 28 with an opening is formed on the bottom surface of the side frame tube 2 by welding or other methods. The screw hole 27 is locked with The opening of the handle 28 is matched, and the screw hole 27 can be connected and fixed with the locking handle 28 through the locking screw, which plays a role of reinforcement. When the utility model needs to be folded, the locking screw is removed, and the rear elbow 25 of the side frame can be folded upward. A rear brake 29 that stops is also installed on the rear wheel 26, and the rear brake 29 is a simple brake.

[0026] Referring again to FIGS. 3 and 5, a folding mechanism is installed under the base 3. The folding mechanism is an X-shaped cross frame 12 connected by a rotating shaft 11. The two ends of the cross frame 12 are respectively connected to the seat tube 13 and the car On the frame 1, the frame 1 can be folded horizontally through a folding mechanism (as shown in Figure 5), the left and right seat tubes 13 are installed with Velcro to form the seat 14, and the seat tube 13 is under There is a support plate 15, the radial section of the support plate 15 is perpendicular to the seat tube 13, a connecting rod 16 extends from the middle of the support plate 15, and the connecting rod 16 is locked on the side frame tube 2 by bolts, so that the support plate 15 is fixed The side frame tube 2 plays a role of supporting the seat tube 13.

[0027] The specific implementation of the utility model is as follows:

[0028] The wheeled walker of the variable wheelchair of the present invention can achieve the dual-use effect of a wheelchair or a walker after simple disassembly or assembly. When the present invention is used as a walker , As shown in Fig. 1, the backing plate 8 is installed on the inner side of the side frame upright pipe 17 to form the support of the walking aid, and the movable foot frame 23 is removed at the same time. When the present invention is used as a wheelchair, as shown in Fig. 4, the backing plate 8 is installed on the outside of the side frame upright pipe 17 to form the backrest of the wheelchair. The foot board 5 is installed on the forefoot tube 10 through the movable foot frame 23 by using tools, so that the feet of the sitting person can be placed on the foot board 5. When you need to fold, as shown in Figure 5, remove the support plate 15 and the Velcro on the seat and the foot pedal 5, and at the same time remove the locking screw, the rear elbow 25 of the side frame can be folded upwards and rotated at the same time. The hand 19 makes the side frame vertical pipe 17 fully inserted into the side frame pipe 2, and through the above operation, the utility model can be folded, effectively reducing the volume. The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model.
