Description

Technical Field

[0001] The utility model relates to the technical field of walking aids, in particular to a walking aid device for the elderly and rehabilitation. Background Art

[0002] A rehabilitation walker is a walking aid for people with mobility problems such as leg fractures, who use their hands and feet to walk. It is generally made of lightweight metal pipes and is developed based on the principles of human mechanics to meet the needs of exercise and walking for the elderly, the weak, and those with mobility problems. Current rehabilitation walkers all slide through universal wheels at the bottom. Existing rehabilitation walkers for the elderly do not have anti-collision and human body protection structures, nor do they have a more reasonable design for users to rest. The height of the handle cannot be adjusted, and rehabilitation training cannot be performed according to the patient's own needs, making them inconvenient to use.

[0003] Chinese patent CN214762097U discloses a rehabilitation walker for the elderly, which improves the stability and anti-collision performance of the rehabilitation walker for the elderly through an auxiliary anti-tilt moving device, and provides the possibility of a rehabilitation walker for the elderly that is anti-collision, highly protective of the human body, convenient for the elderly to rest and go to the toilet, and easy to adjust the handle position by arranging elastic anti-collision components, protective fence devices, seats and human body lifting support devices.

[0004] However, the protective fence device of this solution blocks the walker on all sides. When using the walker, it is necessary to first fix the entire walker, and then rely on others to hold the user and put it into the protective fence device. At least two people are required to assist each time the walker is used or removed. As a result, when there is no assistance from others, the elderly, the weak, or the disabled cannot enter or exit the protective fence device alone, making the use of the walker inconvenient.

DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a walking aid device for the elderly, rehabilitation and walking includes a mobile base 1 and a fence assembly 2, the fence assembly 2 includes a movable plate 21, a first fence 22 and a second fence 23. A first through hole 11 is opened in the center of the mobile base 1, the movable plate 21 is horizontal and the movable plate 21 is slidably arranged in the first through hole 11 along the vertical direction, a second through hole 211 is opened in the center of the movable plate 21, a lifting handle 212 is fixedly arranged at one end of the movable plate 21, there are two first fences 22, and the two first fences 22 are respectively fixedly arranged on the mobile base 1 at positions close to and away from the lifting handle 212, there are two second fences 23, and the two second fences 23 are respectively rotatably connected to a pair of side surfaces on the movable plate 21 that are away from each other, and the rotation axis of the second fence 23 is parallel to the center line connecting the two first fences 22. When the second fence 23 rotates, the movable plate moves in the vertical direction.

[0027] When the walking aid device is needed, the second fence 23 is controlled to rotate from the vertical state. After the second fence 23 rotates, the movable plate 21 will move downward in the vertical direction. Then the user steps on the second fence 23 to enter the second through hole 211, and then rotates the second fence 23 in the opposite direction. When the second fence 23 rotates to the vertical state, the movable plate 21 will move up in the vertical direction, thereby shielding and protecting the user inside the second through hole 211 through the first fence 22 and the second fence 23. Compared with the prior art, the second fence 23 of the utility model can quickly switch between two states: shielding the inside of the walking aid device and opening the inside of the walking aid device. The movable plate 21 drives the second fence 23 to lower its height so that the user does not need to climb into the inside of the walking aid device, so that the second fence 23 used to protect the inside of the walking aid device can be released as needed, thereby facilitating the user to enter the walking aid device alone and conveniently, reducing the difficulty of using the overall walking aid device.

[0028] See also Figure 4-Figure 6As shown: the fence assembly 2 also includes a first gear 24 and a rack 25. A fixed rod 231 coaxial with the rotating axis is fixedly set at the rotating axis of the second fence 23. The fixed rod 231 extends to both ends of the movable plate 21 close to the first fence 22. The first gear 24 is coaxial with the fixed rod 231 and the first gear 24 is fixedly set at the end of the fixed rod 231. The rack 25 is fixedly set on the mobile base 1. The rack 25 extends in the vertical direction and is meshed with the first gear 24.

[0029] When the second fence 23 rotates, the first gear 24 rotates as well. The rotation of the first gear 24 causes the movable plate 21 to drive the second enclosure plate to descend in the vertical direction through engagement with the rack 25. Compared with the prior art, the movable plate 21 of the utility model maintains consistency in movement of the second fence 23, thereby simplifying the operation process and facilitating use.

[0030] See also Figure 5-Figure 6 As shown: a protrusion 213 is fixedly provided on the movable plate 21, a slide groove 12 slidably matched with the protrusion 213 is opened on the movable base 1, the slide groove 12 extends in the vertical direction, and a fixed plate 13 is fixedly provided on the movable base 1 to block the top of the slide groove 12.

[0031] Compared with the prior art, the protrusion 213, the slide groove 12 and the fixed plate 13 of the utility model limit the moving range of the movable plate 21, thereby ensuring that the fence assembly 2 will not be separated from the movable base 1 due to misoperation.

[0032] See also Figure 6 As shown: a friction protrusion 214213 is fixedly provided at the bottom of the movable plate 21. The friction protrusion 214213 is made of rubber and is in a mouth shape. When the movable plate 21 moves to the lowest point, the friction protrusion 214213 contacts the ground.

[0033] Compared with the prior art, the friction protrusions 214213 of the present invention are in contact with the ground to increase the friction between the walking aid and the ground, thereby ensuring that the walking aid will not slide when the user enters and exits the walking aid.

[0034] See also Figure 4-Figure 6 As shown: the mobile base 1 is provided with a first inclined surface 14 that can contact the second fence 23, and the movable plate 21 is provided with a second inclined surface 215 that can contact the second fence 23. The first fence 22 and the second fence 23 are both made of rubber. When the second fence 23 contacts the first inclined surface 14 and the second inclined surface 215 at the same time, the end of the first fence 22 away from its own rotation axis contacts the ground.

[0035] Compared with the prior art, the first inclined surface 14 and the second inclined surface 215 of the present invention limit the maximum rotation angle of the second fence 23, so that the user can step on the second fence 23 to enter the walking aid device.

[0036] See also Figure 6 As shown: the fence assembly 2 also includes a second gear 26 and a transmission belt 27. The second gear 26 is rotatably set on the side of the movable plate 21 close to the first fence 22. The axis of the second gear 26 is parallel to the axis of the first gear 24. The first gear 24 and the second gear 26 are both double gears. The first gear 24 and the second gear 26 are connected by a transmission belt 27. Two second gears 26 that mesh with each other are set on each side of the movable plate 21.

[0037] Compared to the prior art, the second gear 26 and the transmission belt 27 of the present invention enable the two second fences 23 to be in contact with the ground at the same time, so that the entire device can remain stable when the user moves on the second fences 23.

[0038] See also Figure 4 and Figure 6 As shown: one end of a first spring 216 is fixedly arranged on the bottom surface of the movable plate 21, the other end of the first spring 216 is fixedly connected to the top surface of the movable base 1, and a torsion spring 217 is fixedly arranged at the connection between the movable plate 21 and the second fence 23.

[0039] Compared with the prior art, the first spring 216 and the torsion spring 217 of the present invention push the movable plate 21 and the second fence 23 to reset, thereby ensuring that the user can be protected immediately after entering the walking aid device.

[0040] See also Figure 1 and Figure 5 As shown: the fence assembly 2 also includes a limiting plate 15, which is U-shaped and consists of a longitudinal plate and two transverse plates. The limiting plate 15 is horizontally and slidably arranged between the two fixed plates 13 along the rotation axis direction of the second fence 23. The two transverse plates of the limiting plate 15 point to the second fence 23 and can contact the second fence 23. One end of the second spring 151 is fixedly arranged on the longitudinal plate of the limiting plate 15, and the other end of the second spring 151 extends in a direction away from the second fence 23 and the other end of the second spring 151 is fixedly connected to the fixed plate 13.

[0041] When the second spring 151 is in a normal state, the sides of the two second fences 23 that are away from each other are in contact with the two horizontal plates of the limiting plate 15 respectively. At this time, the second fences 23 cannot rotate, and the limiting plate 15 is pushed to move so that the second spring 151 is compressed. At this time, the sides of the two second fences 23 that are away from each other are no longer in contact with the horizontal plates on the limiting plate 15, and the second fences 23 can rotate freely. Compared with the prior art, the limiting plate 15 of the utility model limits the vertical state of the second fences 23, thereby ensuring that the second fences 23 maintain stable protection of the inside of the walking aid.

[0042] The above embodiments only express one or several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
