Description

Rehabilitation walking aid

This creative department has something to do with mobility aids, and more specifically refers to a kind of rehabilitation walking aid.

Press, the conventional rehabilitation walker mainly has a frame, two grips on the frame, and four legs under the frame. When the user wants to move forward, he can hold it on the handle with both hands. And slowly lift the frame forward, and then put the foot post on the ground in front of it, repeating so. It is used to help people with mobility impairments, slow mobility, or rehabilitation, but this kind of rehabilitation walker needs to be raised and lowered constantly, and it is still a great physical burden for the frail people.

Therefore, at present, the structure of a rehabilitation walking aid is mainly composed of a frame, two grips arranged on the frame, and four wheels arranged under the frame, so that the user can walk when he wants to walk. Push forward directly. Although this kind of rehabilitation walking aid can reduce the user's physical exertion, because the wheel body is easy to slide, if the force is not applied in the correct direction or the force is too strong, the user may fall and be injured.

Therefore, how to provide a walking aid that is labor-saving, safe, and conforms to the inertia of the human body when walking is an urgent issue for the relevant industry.

In view of this, in order to improve the prior art, conventional rehabilitation walking aids have problems such as laboriousness, insufficient safety, and non-compliance with human walking inertia. For this reason, this creation provides a rehabilitation walking aid, which includes: a frame; a first wheel set pivotally connected to the bottom end of the frame; a second wheel set pivoted to the frame On the bottom end of the body; two sliding seats, which are slidably connected to the top of the frame body, and can be subjected to external force to move forward and backward linearly with respect to the frame body; a transmission assembly is arranged on the frame body It is connected with the two sliding seats and the first wheel set to transmit the unidirectional force when the two sliding seats slide back and forth to the first wheel set To provide the power for the rotation of the first wheel set, so as to achieve the effects of labor saving, good safety, and conforming to the habitual movement of the human body when walking.

Therefore, the foregoing is an introduction to the various components and combinations of the rehabilitation walking aid 100 provided by a preferred embodiment of this creation, and then the characteristics of its use are introduced as follows: First, when the user wants to use this creation When assisting in rehabilitation or walking, the user can hold both hands on the grip 41 of each sliding seat 40, and use the inertia of the human body's hands to swing back and forth when walking to move forward and backward. The two sliding seats 40 are driven to move forward and backward, that is, when one of the sliding seats 40 is driven to move forward, the other sliding seat 40 will be driven to move backward (as shown in Figures 5 to 7 As shown), the two sliding seats 40 are reciprocated slidingly one after the other.

Among them, the sliding seat 40 that slides forward will be driven by the row of teeth 42 to drive the one-way gear 511 to rotate, and the transmission shaft 512 is synchronously driven to rotate, so that the transmission shaft 512 transmits the rotational power to the first belt set 52. The second belt set 53 and the third belt set 54 are driven by the third belt set 54 to rotate the interlocking shaft 22 and the interlocking wheel 21 of the first wheel set 20 so as to move the sliding seat 40 forward The unidirectional force of time is transmitted to the first wheel set 20 to serve as the power source for the rotation of the first wheel set 20, thereby achieving the effect of saving effort. Of course, when the sliding seat 40 slides backwards, the one-way gear 511 will prevent the power from being transmitted to the transmission shaft 512 through the one-way clutch 514, so that the user can hold the original creation. Improve safety.

Moreover, when the sliding seat 40 slides back and forth, the row of teeth 42 moves back and forth in the sliding path 162 (as shown in Figure 7), and the side of the row of teeth 42 is affected by the rolling wheels 163. Rolling guide, and can improve the smoothness of sliding.

In this way, this creation not only allows the hands of the human body to still show the inertia of swinging back and forth when walking, but also can drive the sliding seat to transmit the power to the first wheel set by swinging the hands before and after, so as to achieve compliance. The effect of ergonomics, labor saving and safety is better.

In addition, when the user wants to park the creation, the fastener 63 of the locking unit 60 can be pulled to the braking position (as shown in the eighth figure), so that the binding member 62 is pressed against the transmission assembly 50 On the transmission shaft 512, a braking effect is formed to position the creation to prevent slippage. When you want to use this creation, pull the fastener 63 of the lock unit 60 to the release position (as shown in the ninth figure), that is, release the transmission shaft 512 so that the power can pass through the The transmission shaft 512 is transmitted to make the operation smooth.

The above disclosures are only the preferred embodiments provided by this creation, and are not intended to limit the scope of implementation of this creation. All relevant artisans in this technical field who make equal changes based on this creation should belong to this creation. The scope of coverage.
