Description

  The present invention relates to a walking assistance device, and more particularly to a foldable walking assistance device.

  As the birth rate and mortality rate gradually decline with the development of pharmaceutical technology, the ratio of elderly population in Japan has increased significantly, and the aging society has become a serious issue that cannot be ignored. And the problem becomes significant. For example, elderly people tend to collapse unexpectedly during shopping and daily activities (for example, walking) because their activity and behavioral agility are worse than young people due to joint degeneration and physical strength attenuation. It should be noted that due to the aging of the elderly's physiological functions, even if the fall is not severe, it is difficult to stop fractures and stop bleeding at the wound, and there is a possibility that residual illness may occur.

  In order to solve the above problems, walking assist devices for the elderly have been developed and marketed. By using such a walking assistance device, elderly walking is stable and smooth, and when the elderly walking is unstable, the walking assistance device supports the center of gravity of the body. It is possible to stabilize the walking again, avoid the danger of falling, and increase the safety of walking for the elderly.

  The two braking mechanisms 90 each have a braking handle 92, a braking wire 94, and a braking member 96. The brake handle 92 is assembled to the handle end 48 of the handrail frame 40. The braking member 96 is assembled to the lower end of the rear foot 32 of the rear frame 30 and can press the rear wheel 36 or be detached from the rear wheel 36. The brake wire 94 is connected to the brake handle 92 and the brake member 96. As a result, the brake handle 92 can control the brake member 96 to press the rear wheel 36 or to be detached from the rear wheel 36. Since the braking mechanism is not the focus of research and development of the present invention, description thereof is omitted.

  Referring to FIG. 5, the user adjusts the height of the handrail frame 40 according to his / her height before using the walking assist device 10 according to the present invention, so that the two handle ends 48 of the handrail frame 40 are adjusted. Can be easily grasped. When the user wants to walk using the walking assist device 10 according to the present invention, both hands hold the two handle ends 48 of the handrail frame 40, so that the walking assist device 10 supports the center of gravity of the user's body. To do. When the user is walking, the front wheel 29 and the rear wheel 36 rotate according to the user's walking speed, and the front wheel 29 turns according to the user's walking direction. Thereby, the user can walk easily by using the walking assist device 10 according to the present invention. The two braking mechanisms 90 allow the user to decelerate the two rear wheels 36 and lower the speed of the walking assist device 10. Thereby, it is possible to increase the safety of the walking assist device 10.

  When he / she wants to take a rest, the user can sit on the seat plate 60 of the walking assist device 10 and abut his / her back on the backrest rod 46. Since the upper surface of the seat plate 60 is the anti-slip surface 61, the user can be prevented from slipping and falling from the seat plate 60. Since the backrest rod 46 has a U-shape, the user can be prevented from falling from the left and right sides of the seat plate 60.

  Referring to FIGS. 5 and 7, after using the walking assistance device 10, when the walking assistance device 10 is to be stored or transported, the rear end of the seat plate 60 is pulled up to raise the engagement groove of the engagement portion 64. 65 is disengaged from the support rod 34 of the rear frame 30, the rear end of the seat plate 60 is raised, and the two links 70 pivotally attached to the pivot attachment portion 66 of the seat plate 60 rotate together with the seat plate 60. Thus, the rear frame 30 is driven and displaced to the front frame 20, and the first folding rod 82 and the second folding rod 82 of the folding rod unit 80 are folded. Referring to FIGS. 8 to 11, when the two rear legs 32 come into contact with the two front wheels 29, the distance between the front frame 20 and the rear frame 30 is the smallest. The volume can be folded, and the space occupied by the walking assist device 10 can be reduced.

  Referring to FIG. 11, when it is desired to use the walking assist device 10 again, by pushing down the rear end of the seat plate 60, the two links 70 are displaced rearward together with the rear frame 30, and the rear frame 30 is moved from the front frame 20. Simultaneously with the separation, the first folding rod 82 and the second folding rod 82 of the folding rod unit 80 are separated from each other and deployed. When the engaging groove 65 of the seat plate 60 is engaged with the support rod 34 of the rear frame 30, the walking assistance device 10 is in the deployed state, and the user can assist walking using the walking assistance device 10.

  According to the walking assist device of the present invention, the user can adjust the height of the handle according to his / her height, and the two front wheels can be turned in accordance with the user's walking direction during the march, and the speed is too high. Sometimes, the user can decelerate by the two braking mechanisms, so that the user can easily walk using the walking assistance device and can secure the safety of walking. Moreover, according to the walking assistance apparatus which concerns on this invention, the expansion | deployment and folding of a walking assistance apparatus can be completed quickly and easily by pulling up or pushing down the rear end of the seat board. And by folding the walking assistance device according to the present invention, it is possible to reduce the entire volume of the walking assistance device, it is possible to reduce the occupied space, the walking assistance device with a smaller force It is transportable and convenient to transport.

  The present invention can be applied to a walking assist device.
