Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail installed on a wheelchair, and more particularly to a handrail for a cared person who can stand up or sit down with the help of a caregiver such as a cerebral infarction. It is.

[0002]

2. Description of the Related Art A care receiver's stand-up or sitting movement such as cerebral infarction in which the caregiver can stand up or sit down is dependent solely on the caregiver's assistance.

[0003]

A care recipient, such as a cerebral infarction who uses a wheelchair capable of standing up and sitting, can use both arms of the upper body, or either of the left and right arms, with the help of the caregiver. It was thought that he could use his power to get up on his own.

SUMMARY OF THE INVENTION In view of the above, the present invention makes it possible for a caregiver using a wheelchair capable of standing up and sitting to easily stand up or sit down by himself with the assistance of a caregiver, thereby reducing the burden on the caregiver. An object of the present invention is to provide a handrail for a wheelchair.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a wheelchair.
A fixed handrail that is attached to one or both frames of a wheelchair, extends vertically, and has a fixed height L
The gist of the present invention is a handrail for a wheelchair, which comprises a grip bar having a character shape and an armrest frame extending from a predetermined position of the grip bar.

The gist of the armrest frame is to be slightly shorter than the length from the ankle to the elbow of the cared person.

[0007] The hand grip terminal has a handrail that has a space for easily putting a thumb thereon and can exert more strength.

The gist of the invention is that a rubber pad is attached to the L-shaped portion of the armrest frame.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram of a handrail for a wheelchair according to the present invention. It should be noted that the wheelchair is braked during the standing and sitting operations.

FIG. 2 is a perspective view of the wheelchair of the present invention. As shown in this figure, a grip bar 24 which is attached to one or both frames of the side frame of the wheelchair 1 and extends vertically 21 and becomes an L-shaped 22 at a predetermined height and an armrest extending from a predetermined position of the grip bar A handrail attached and fixed to a wheelchair, characterized by being composed of a frame 23, having a space 24a to which a thumb can be put, and a grip bar being drawn with a contact point between an elbow and an armrest frame as a fulcrum. The cared person can stand up by easily leaning forward, moving the center of gravity of the upper body easily, and reducing the burden of helping or the caregiver. The armrest frame has a rubber pad 25 so that it can be used safely even by older people.

FIG. 3 illustrates an embodiment of the present invention. (A) is a side view. (B) is a front view thereof, and (c) is a diagram in which a rising operation is started by itself.

First, while holding the elbow on the 25 L-shaped armrest frame, hold the 24 grip bars with the right hand (FIGS. 3A and 3A).
-B) When the gripping rod is pulled, the center of gravity of the upper body is smoothly moved around the armrest frame and the elbow as a fulcrum (FIG. 4), the waist is lifted, and a standing posture can be taken (FIG. 3).
c). When a force is applied in a direction of pressing the floor downward with both feet or one foot while using the gripping stick as a cane, the posture in which the whole body is lifted up can be taken. Then you can stand upright from your wheelchair.

If the reverse of the rising operation is performed in an upright state, the user can sit on a wheelchair.

In another embodiment of the present invention, if a part of the right arm shown in FIG. 4 is configured to cover the periphery of the armrest frame with an elastic rubber pad, it can be used safely for elderly people with weak bones. .

Various embodiments can be adopted without departing from the spirit of the present invention. For example, in the embodiment of the present invention, the case where the right arm function is good has been described, but if the left arm function is good, it is possible to wear it on the left side of the wheelchair if both functions are normal, it is also possible to wear it on both sides, It is also possible to adopt a configuration in which the grip bar is rotated and folded.

[0016]

As described above, the present invention is mounted on one or both frames of a wheelchair, and extends vertically and has an L-shape at a predetermined height, and an armrest frame extending from a predetermined position of the grip bar. The gist is a handrail for wheelchairs, which is characterized by the fact that despite the simple structure, caregivers such as cerebral infarction using a wheelchair that can stand up and sit down with the help of a caregiver can stand up on their own. It can reduce the burden on the caregiver and facilitate the caregiver's spontaneous rising and sitting movements, which will be increasingly needed in an aging society in the future It is a useful invention.

Further, the projecting portion at the lower part of the gripping bar portion is essentially an armrest frame that is slightly shorter than the length from the ankle to the elbow of the cared person. Attachment (Fig. 4-A) At the same time as pulling his / her body, using the contact point between the elbow and the armrest frame as a fulcrum, the center of gravity of the upper body is moved and the standing posture is easily taken. Alternatively, if a force is applied in a direction of pressing the floor surface downward with one foot, the entire body can be lifted upward, so that it is possible to easily stand upright.

Since the hand grip terminal has a space for easy thumb application and has a handrail that can exert more strength, the operation of pulling its own body by attaching an elbow to a part of the armrest frame can be performed more smoothly. is there.

Further, since it is essential that a rubber pad is attached to the L-shaped portion of the armrest frame, it is possible to cope with a case where a person who has a weak arm bone, such as an elderly person, is used. You can do it. That is, it is useful not only for a cared person such as a cerebral infarction who can stand up or sit down with the help of a caregiver, but also for the deterioration of various functions due to aging and maintenance of functions and prevention of disability.
