The operation lever 220 has a configuration in which a mounting portion 221 is provided on the distal end side, which is one end of the operation shaft 225, and a pressing portion 222 is provided on the mounting portion 221. The pressing portion 222 of the operation lever 220 is inserted into the space between the wall plate portions 212 through the opening 223 between the wall plate portions 212 facing the wall surface 214 of the guide member 210. It is attached to the back surface 22r of the top plate 22X of the support base 22. That is, for example, the attachment lever 221 is attached to the rotation center shaft 231 projecting from the back surface 22r of the top plate 22X of the support base 22 so as to be orthogonal to the back surface 22r. Is configured to be rotatable around the rotation center. A nut 232 for preventing the attachment portion 221 from being detached is attached to a screw portion (not shown) formed at the tip of the rotation center shaft 231.

The biasing spring 230 has, for example, one end connected to the mounting portion 211 of the guide member 210 and the other end connected to the operation shaft 225 of the operation lever 220.
Then, usually, the other end 226 of the operation shaft 225 is urged by the urging spring 230 in a direction (one direction) away from the side plate 22Y, and the pressing portion 222 of the operation lever 220 is moved between the through holes 213 and 213. By keeping the outer surface of the rope 49 pressed, the rope 49 is sandwiched between the pressing portion 222 and the wall surface 214 (locked state).
That is, as shown in FIG. 10A, a rotational force in the direction in which the pressing portion 222 approaches the wall surface 214 is constantly applied to the operation lever 220 by the spring force of the urging spring 230, and The end side is set in a state in which it cannot be pulled out (locked state).

  Further, as shown in FIG. 10B, the operating shaft 225 of the operating lever 220 is gripped against the force of the urging spring 230, and the other end 226 of the operating shaft 225 is brought close to the side plate 22Y to press the operating lever 220. By rotating the portion 222 in a direction away from the wall surface 214 (the direction opposite to the one direction), the state in which the other end of the rope 49 cannot be pulled out by the pressing portion 222 is released, and the other end of the rope 49 is supported. The drawer is set in a drawable state in which the drawer can be pulled away from the table 22.

The wall 214 and the pressing portion 222 facing the wall 214 are formed with blades 226 and 226 that bite into the outer surface of the rope 49 passed between the through holes 213 and 213. Regarding the orientation of the blades 226 and 226, the resistance increases in the direction in which the other end of the rope 49 is pulled out, and the resistance is increased in the direction in which the rope 49 is pulled back by the spring force of the tension coil spring 48 (elastic support means 5A). It is formed so as to be smaller.
Therefore, when the other end of the rope 49 is set to be able to be pulled out by grasping the operation shaft 225 of the operation lever 220, the tension coil spring 48 is applied to the other end of the rope 49 by the spring force of the tension coil spring 48. The pulling force is applied to the side, and the connecting tool 51 at the other end of the rope 49 can be pulled out by pulling in a direction away from the support base 22 by human power.
Then, when the hand is released from the operation shaft 225 of the operation lever 220, the pressing portion 222 is urged in a direction approaching the wall surface 214 by the spring force of the urging spring 230, and the blade 226 provided on the wall surface 214 and the pressing portion 222. , 226 bite into the outer surface of the rope 49, that is, the other end of the rope 49 is set in a state in which it cannot be pulled out. When the pull-out state is set, the connecting tool 51 at the other end of the rope 49 cannot be pulled by human power in a direction away from the support base 22, but the other end of the rope 49 is The connecting tool 51 is configured to be gradually pulled toward the tension coil spring 48 by a force so that the connecting tool 51 can approach the support base 22.
That is, after the attachment tool B of the user A and the connection tool 51 are connected to each other, if the pull-out state is set, the slack of the rope 49 is gradually eliminated.

The provision of the connecting means 5 and the pull-out restricting means 200 of the connecting means 5 allows the user to grip the operating shaft 225 of the operating lever 220 when connecting the mounting tool B and the connecting tool 51, thereby enabling the rope 49 to be connected. Since the connecting tool 51 at the other end of the rope 49 can be easily pulled out, the connecting work for connecting the connecting tool 51 provided at the other end of the rope 49 and the connecting portion C of the mounting tool B worn by the user A is performed. It will be easier.
After the coupling operation is completed, the rope 49 is sandwiched between the blade 226 of the pressing portion 222 and the blade 226 of the wall surface 214 by releasing the operation shaft 225 of the operation lever 220. Is prevented from being pulled out in the direction away from the support base 22. Therefore, after the user A is connected to the connecting tool 51 of the rope 49 of the walking assistance device 1 via the wearing tool B, the posture of the user A is less likely to collapse, and the falling of the user A can be prevented. . At this time, the pulling-back force is applied to the rope 49 by the spring force of the tension coil spring 48 (elastic support means 5A), and the rope 49 is moved so that the position of the connecting tool 51 gradually approaches the drawing hole 52 of the support base 22. Is pulled back, so that the slack of the rope 49 is gradually eliminated.
Therefore, the user A can perform the standing and sitting operation in a stable state in which the hanging position connected to the connecting tool 51 approaches the support base 22 during the assisting operation, and does not fall in the walking mode. As a result, a safe walking operation can be performed.
That is, the connecting operation of connecting the connecting device 51 and the connecting portion C of the mounting device B worn by the user A can be easily performed, and the user A is connected to the connecting device 51 of the rope 49 of the walking support device 1. The walking support device 1 having the function of preventing the user A from falling later is provided.

Next, a method of using the walking support device 1 according to the first embodiment will be described.

Then, the walking support device 1 is moved to a position near the seating portion D. Thereafter, the changeover switch 42 is set to the seating operation support side (the side for lowering the elevating body 10), and the motor 83 is driven to lower the elevating body 10 to the lowest position as shown in FIG. Then, the support base 22 is inclined downward toward the rear. Then, the user A or the assistant grasps the operation shaft 225 of the operation lever 220, and the connecting tool 51 at the other end of the rope 49 approaches the connecting portion C of the mounting tool B worn by the user A. Pull out. In this case, since the connecting tool 51 can be easily pulled out, the connecting operation for connecting the connecting tool 51 provided at the other end of the rope 49 and the connecting portion C of the mounting tool B worn by the user A becomes easy. In addition, during this connection work, the brake 32 is applied to the wheels 32 of the rear turning casters 31R by the braking component 100, so that the walking support device 1 may be inadvertently moved during the connection work. Can be prevented, and the user A can perform the connecting operation safely.

  As shown in FIG. 11B, after the coupling operation is completed, the hand is released from the operation shaft 225 of the operation lever 220, the changeover switch 42 is set to the upright operation support side, and the motor 83 is driven. As a result, the elevating body 10 moves up, and the support table 22 also moves up while changing its posture, so that the user A connected to the support table 22 performs a standing support operation. During the standing support operation, the braking means 110 applies a brake to the wheels 32 of the rear turning casters 31R (braking operation state). Will be performed. In addition, during the standing support operation, the pull-out restricting means 200 prevents the other end of the rope 49 from being pulled out in a direction away from the support base 22, so that the user A can be prevented from falling. Further, during the standing support operation, the rope 49 is pulled back by the spring force of the extension coil spring 48 (elastic support means 5A) so that the position of the connecting tool 51 gradually approaches the drawing hole 52 of the support base 22. Since the slack of 49 is gradually eliminated, the user A can perform the standing operation in a stable state in which the hanging position connected to the connecting tool 51 is close to the support base 22.

  Then, as shown in FIG. 11C, when the elevating body 10 reaches the uppermost position and the standing support operation is completed, the brake release surface 132 of the original section 130 and the contact 143 of the follower 140 come into contact with each other. By doing so, the brake wire 118 is pulled, and the braking means 110 is automatically set to the brake release state. That is, after the standing-up assisting operation of the user A is completed, the walking assisting device 1 shifts to the walking mode without any troublesome operation for canceling the braking operation of the braking means 110 by the assistant or the user A, The user A can walk while being connected to the walking support device 1.

  Further, at the time of seating, by setting the changeover switch 42 to the seating operation support side and driving the motor 83, the elevating body 10 descends, and the contact between the original section 130 and the contact 143 of the follower 140 is released. As a result, the braking means 110 is automatically set to the braking operation state. Therefore, the walking support device 1 is prevented from being inadvertently moved during the seating assisting operation, and the user A can perform the seating assisting operation stably and safely.

During the support of the standing motion, the support base 22 of the support member 20 rises while changing its posture so as to gradually rise from the state in which the rear end is lowered in accordance with the standing motion of the user A. The person A can perform a natural standing operation.
In addition, at the time of assisting the seating operation, the support member 20 gradually changes the rear end of the support base 22 from the state where the upper surface 22t of the support base 22 is horizontal or almost horizontal to the user A's sitting operation. Since the user A descends while changing the posture so as to descend, the user A can perform a natural sitting operation.
