Abstract

PROBLEM TO BE SOLVED: To move the wheelchair from a wide space to a narrow space and to change a direction without depending on training for manipulating a wheelchair. SOLUTION: A sheet-like guiding board 1 forming guiding grooves 3 for guiding the wheelchair, both ends of which are large in width and the cross sections of which are inverse trapezoides, is fixed to a boundary part for moving from a wide space to a narrow one and a narrow space requiring the change of a direction. Thus, it is easy to pass through without training of the wheel chair only by putting the wheelchair in the grooves and pushing it.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool used in the field of welfare and nursing care, and more particularly to a wheelchair guide plate for guiding a wheelchair used by a patient during medical treatment or a physically handicapped person.

[0002]

2. Description of the Related Art In a wheelchair, at a turning point 15 such as a floor, a corridor or a veranda as shown in FIG. 5, change direction at right angles as indicated by an arrow A to descend a passage 13 with a narrow slope. Or a turning place 1 in a narrow space such as a corridor in front of the elevator 14 as shown in FIG.
Performing the direction change in arrow direction B in 5 is a more difficult task for a wheelchair user such as a patient during medical treatment or a physically handicapped person than a normal person can imagine. Heretofore, for this purpose, training has been required until the driver can freely operate the wheelchair, and if that is not possible, he or she has to rely on a caregiver for such traffic.

[0003]

However, in order for a wheelchair user to be able to freely control a wheelchair, it is necessary to carry out high-level training, which is physically and mentally difficult for the wheelchair user. Was painful. In addition, no matter how much training is carried out, there are cases where a necessary skill cannot be acquired depending on the physical strength or ability of a wheelchair user. For this reason, it is difficult to always take care of the caregiver, and even if there is a caregiver, there is a problem that a large care cost is required.

The present invention has been made in view of the above circumstances, and enables a wheelchair user to change directions from a wide place to a narrow place or a narrow place without obtaining wheelchair control skills through special training. It is an object of the present invention to provide a wheelchair guide plate that can easily perform the operation.

[0005]

In order to achieve the above object, in a wheelchair guide plate of the present invention, a guide groove for guiding wheels of a wheelchair is formed by providing irregularities on a seat, and is provided on a floor. Install or attach or fix for use.

In the wheelchair guide plate of the present invention,
When the wheelchair comes off from the guide groove for guiding the wheelchair, a means for detecting the wheelchair is provided. The detection of the wheel departure is preferably provided with a function of giving a voice notice of departure or giving an instruction of a return operation, and a sign light for notifying others of the departure.

[0007] The wheelchair guide plate of the present invention is configured as described above, and by using this, it is possible to move from a wide place to a narrow place or change directions in a narrow place without training.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a wheelchair guide plate of the present invention will be described in detail with reference to examples.

FIG. 1 shows a first embodiment of a wheelchair guide plate according to the present invention. FIG. 1 (a) is a schematic perspective view thereof, and FIG.
(B) is a partial sectional view thereof. As shown in FIG. 1A, a wheelchair guide plate (hereinafter, referred to as a guide plate) 1 of the present embodiment.
Is formed by forming a guide groove 3 for guiding both wheels of a wheelchair on a sheet 2 made of hard rubber having a certain thickness. The shape of the guide groove 3 is such that the width of the groove is increased toward both ends of the sheet 2 (the entrance in the case of one-way traffic), and the width of the groove is reduced toward the center of the sheet 2.
As shown in (b), both side surfaces of the guide groove 3 are formed so as to have a certain inclination angle in accordance with the degree of the curve, so that the two inclination surfaces approach as they approach downward. for that reason,
Once the wheelchair is guided into the guide groove 3, both wheels of the wheelchair can always move in contact with the lowermost surface of the guide groove 3. The wheelchair can move smoothly only by pushing in the guide groove 3 without contact. Also,
The periphery of the seat 2 is inclined from the lower surface to the upper surface, so that the wheelchair can easily enter the guide plate 1 from the floor surface.

FIG. 2 shows a modified embodiment of the wheelchair guide plate according to the present invention. The common entrance 3d of the guide groove 3 of the guide plate 11 is straight forward and the entrance 3 in the left and right directions.
a, 3b, and 3c are provided, and a guide groove 3 through which a wheelchair can enter and exit from these three directions is formed.

The above-mentioned guide plates 1 and 11 may be merely installed on the floor surface. However, it is preferable that an adhesive is applied to the back surface in advance, and that the guide plates 1 and 11 be placed at the position of the direction changing place 15 shown in FIGS. A method of arranging and peeling off the adhesive seal to adhere to the floor surface, or providing guide holes 1 and 11 with small holes, and having a female screw such as a nut plate previously fixed to the floor surface (see FIG. And fixed by a method such as screwing.

FIG. 3 is a schematic perspective view of a second embodiment of the present invention. The guide plate 21 of the present embodiment is different from the guide plates 1 and 11 of the first embodiment and the modified examples in that the pressure-sensitive sensor 4 for detecting a wheel-off state from the guide groove 3 of the wheelchair and the pressure-sensitive sensor 4 A detection circuit 5 for amplifying a small signal, an audio circuit 6 in which an audio content to be generated is written when the output of the detection circuit 5 reaches a level equivalent to derailing, and an audio generated upon receiving the output of the audio circuit 6 Speaker 7 and a power supply connection terminal 8 are incorporated.

In the audio circuit 6, for example, a cautionary statement such as "The wheel has left the wheel" or a message such as "The wheel has left the wheel. Please stop and switch slightly to the right and proceed gradually" Various return operation guidances are recorded as voices, and these voices can be generated when the wheelchair comes off the wheel and rides on the pressure sensor 4. According to the present embodiment, even when the wheelchair user gets out of the wheel, the situation can be grasped by voice and the direction can be safely changed.

FIG. 4 is a schematic perspective view of a third embodiment of the present invention. As shown in the drawing, the present guide plate 31 includes the pressure-sensitive sensor 4 on the guide plates 1 and 11 of the first embodiment and its modification.
A detection circuit 5, a logic circuit 9 for generating a blink signal when its output reaches a level equivalent to derailing, and a connection terminal for output and power supply of the logic circuit 9 are incorporated. The logic circuit 9 is configured by being connected by a cable 12. This sign light 10
Can be installed in a janitor's office or the like so that a janitor can monitor the traffic condition of the wheelchair and assist in the safety of the wheelchair should the wheelchair fall off.

The shape of the guide groove 3 is not limited to the shape shown in each embodiment. For example, both sides of the guide groove 3 are raised in a convex shape, and the inclination of both sides is curved. It is also possible.

[0016]

The wheelchair guide plate of the present invention is constructed as described above. Even if a wheelchair user cannot acquire the necessary skills for traffic through training, the wheelchair can be inserted into the guide groove having both ends widened. By simply pressing the button, it can be moved along the guide groove, and it can be easily moved from a wide place to a narrow place or turned in a narrow place.
