  Since the cared person is moved to another place by the transfer vehicle, when the cared person is put on the transfer car, the transfer car may move without permission if there is no brake mechanism. In addition, when using a walking assistance vehicle as an aid for self-supporting walking, the walking assistance vehicle may move without permission if there is no brake mechanism. If the brake mechanism is provided, the above-mentioned problem can be solved. However, the caregiver and the cared person have to perform the brake operation themselves, which is troublesome. Therefore, there has been a demand for a device that maintains a stop state until the start of use of a transfer vehicle or a walking assistance vehicle and that automatically releases the brake when used.

In order to solve the above problems, a walking assist and transfer vehicle of the present invention includes a main body frame, a body platform that is movably supported with respect to the main body frame, one end portion engaged with the body platform, and the other end portion. Is a vertical operating rod that engages with one side of an L-shaped arm that is rotatably supported by the main body frame, a support rod that is connected to the end of the other side of the L-shaped arm, and that can be grounded at one end, and a supporting rod And an urging means for urging the substrate toward the ground surface.

According to the transfer assist / transfer vehicle of the present invention, when the cared person becomes physically difficult to use for walking assist, it can be used as a transfer car, and the brake operation can be performed by the carer or the cared person. Even if the caregiver does not perform it, the brake is automatically released at the time of use, so that the walking assist / transfer vehicle is kept stopped until the cared person gets in a safe position.

It is a perspective view which shows the outline of the walking assistance combined transfer vehicle of this invention. It is an enlarged view which shows the movable support state with respect to the frame of the body platform of the walking assistance combined transfer vehicle of this invention. It is a figure which shows the auxiliary stand which moves on the body mounting board of the walk assistance combined use transfer vehicle of this invention. It is a figure which shows the other Example of the auxiliary stand of FIG. 2, (a) shows a self-propelled auxiliary stand, (b) shows a belt conveyor type auxiliary stand. It is explanatory drawing which shows the brake action of the walk assistance combined transfer vehicle of this invention, (a) is a figure of the state before putting a person at the time of using as a transfer vehicle, (b) is a person at the time of using as a transfer vehicle (C) is a figure of the state before the use at the time of using as a walk auxiliary vehicle, (d) is a figure which shows the state in use at the time of using as a walk auxiliary vehicle. It is a figure which shows the use condition of the walking assistance combined transfer vehicle of this invention, (a) is a figure in the case of using as a walking assistance vehicle, (b) is a figure in the case of using as a transfer vehicle.

1 to 3 are drawings relating to the structure of the walking assist and transfer vehicle of the present invention. In FIG. 1, 1 is a main body frame, and 2 is a body platform. Further, as shown in FIG. 2, the protrusion 3 formed on the side surface of the body platform 2 engages with the guide groove 4 a in the guide rail 4 fixed to the main body frame 1, so that one end of the body platform 2 is formed. The portion 2a is movably supported with respect to the main body frame 1. Furthermore, one end portion 5 a of the vertical operation rod 5 is in contact with the body platform 2. The auxiliary stand 6 that moves on the body resting plate 2 shown in FIG. 3 can be installed as necessary. When the care recipient is moved to the vicinity of the center of the body placing plate 2, the care recipient is placed on the auxiliary base 6 in a lying state, and then the auxiliary base 6 is placed via the wire 8 using the power of the electric motor 7. To move to a predetermined position.

FIG. 4 is a view showing another embodiment of the auxiliary stand, and FIG. 4 (a) shows a state in which power and a self-propelled mechanism are built in the auxiliary stand 6, and the auxiliary stand 6 carries the cared person by itself. It can move to near the center of the body platform 2. In FIG. 4B, the surface of the auxiliary base 6 is like a belt conveyor, and the auxiliary base 6 itself does not move, but if the cared person is placed on the auxiliary base 6 and the belt conveyor is operated, the cared person Can be moved to the vicinity of the center of the body placing plate 2.

FIG. 5 is an explanatory view showing the brake operation of the walking assist and transfer vehicle of the present invention. FIG. 5A is a state diagram before placing a person when used as a transfer vehicle. The other end portion 5b of the vertical operation rod 5 is an L-shaped arm 9 that is rotatably supported by the main body frame 1. FIG. It is in contact with one side 9a. A rotation fulcrum 9 b of the L-shaped arm 9 is a corner of the L-shaped arm 9. One end 10a of the support bar 10 is connected to the tip 9d of the other side 9c of the L-shaped arm 9, and the foot 11 is coupled to the other end 10b of the support bar 10, and the grounding surface direction is connected by the coil spring 12. Is being energized. In this state, since the foot 11 is in contact with the ground, the transfer vehicle is in a braked state, and movement is prevented.

FIG. 5 (b) is a diagram of a state where a person is placed when used as a transfer vehicle, and the vertical operation rod that is in contact with the body platform 2 as the body platform 2 sinks downward due to the weight of the person. 5 also moves downward, so that the other end portion 5b of the vertical operating rod 5 pushes one side 9a of the L-shaped arm 9, and the L-shaped arm 9 rotates in the counterclockwise direction around the rotation fulcrum 9b. . As a result, the support bar 10 connected to the tip 9d of the other side 9c of the L-shaped arm 9 is lifted against the urging force of the coil spring 12, and as a result, is coupled to the other end 10b of the support bar 10. Since the foot portion 11 is separated from the ground contact surface, the transfer vehicle becomes movable with the brake released.

FIG.5 (c) is a state figure before use at the time of using as a walk auxiliary vehicle, and shows the state just before rotating the body platform 2 with respect to the main body frame 1, and fixing the body platform 2. FIG. Yes. In this figure, since the other end 2b of the body platform 2 and the L-shaped arm 9 are not yet in contact with each other, the walking assistance vehicle is in a braked state as in the state of FIG. 5 (a). Yes.

FIG. 5 (d) is a diagram showing a state in use when used as a walking assistance vehicle. When the body platform 2 is further rotated with respect to the main body frame 1 from the state of FIG. 5 (c), Since the other end 2b of the body platform 2 pushes one side 9a of the L-shaped arm 9, the walking assistance vehicle is in a state in which the brake is released, and can move, as in the state of FIG. A notch 9e is provided on one side 9a of the L-shaped arm 9, and it engages with the other end 2b of the body platform 2 to be locked, so that the brake is always released during movement. maintain.

6A and 6B are diagrams showing a use state of the walking assistance combined transfer vehicle according to the present invention. FIG. 6A shows a case of using as a walking auxiliary vehicle, and FIG. 6B shows a case of using as a transfer vehicle. .
