  The handle portion 30 includes a front handle 301, a front grip 302, a rear handle 303, a rear grip 304, an armrest 305 fixed to the armrest bracket 203, a belt 306, a belt bracket 307 fixed to the armrest 305 and holding the belt 306, inner A lever 308 for adjusting the height of the pipe 202 is provided.

  In FIG. 2, the AA cross section of the support | pillar part 20 shown in FIG. 1 is shown. However, in FIG. 2, except for the lever 308, the display of the handle portion 30 is omitted.

  In the configuration shown in FIG. 2, the outer pipe 201 of the support 20 is fixed to the base frame 103. An inner pipe 202 is inserted into the outer pipe 201. The cross-sectional shape of the outer pipe 201 and the inner pipe 202 in the direction perpendicular to the paper surface in FIG. A slider 220, which includes a plurality of rollers 221 and a holding plate 222 for holding the plurality of rollers 221, is disposed between the outer pipe 201 and the inner pipe 202 on the surface of each square cross section. There is. The inner pipe 202 is guided by the slider 220 and can slide in the vertical direction with respect to the outer pipe 201.

  Inside the inner pipe 202, a gas spring 210 is inserted. In the gas spring 210, a mounting bracket 215 formed at the lower end is supported by a pin 214 fixed to a bracket 2012 attached to the base frame 103. At the tip of the rod 211 of the gas spring 210, an operating piece (push rod) 212 slidable with respect to the rod 211 to switch between the locked state and the unlocked state of the operation of the gas spring 210 is attached. . Further, the vicinity of the tip end portion of the rod 211 is joined to a block 213 fixed to the inner pipe 202.

  The lever 308 is rotatably attached to a support member 3081 fixed to the armrest bracket 203 by a pin 3082. The lever 308 is normally in a state where the left side is lowered with the pin 3082 in the state shown in FIG. 2, and the vicinity of the right end portion of the lever 308 is from the operation piece 212 of the end portion of the rod 211. is seperated.

  The gas spring 210 is locked in a state where the actuating piece 212 is not restrained by the lever 308, that is, in a state where the lever 308 is not in contact with the actuating piece 212, the rod 211 does not move and the rod 211 keeps a constant position. There is.

  On the other hand, in the state where the operating piece 212 is restrained by the lever 308, that is, in the state where the lever 308 pushes down the operating piece 212, the lock of the gas spring 210 is released. In this state, the rod 211 ascends or descends according to the load applied to the rod 211 with respect to the output of the gas spring 210. That is, when the load applied to the rod 211 is larger than the output of the gas spring 210, the rod 211 descends (or retracts). On the other hand, when the load applied to the rod 211 is smaller than the output of the gas spring 210, the rod 211 ascends (advances).

  The tip portion of the inner pipe 202 is joined to the armrest bracket 203 by welding or the like. Further, a cushion pipe A: 204 is joined to the arm rest bracket 203 by welding or the like substantially in parallel with the inner pipe 202 on the same side as the side to which the inner pipe 202 is joined.

  A pin 2051 is fixed in the vicinity of the end of the cushion pipe A: 204 opposite to the side joined to the armrest bracket 203, and a nylon wheel 205 is rotatably attached to the pin 2051. . The pin 2051 is attached at such a position that the cushion pipe A: 204 does not contact the outer pipe 201 in a state where a part of the outer peripheral surface of the wheel 205 is in contact with the outer pipe 201.

  A cushion pipe B: 207 is connected to the cushion pipe A: 204 in a substantially perpendicular direction by welding or the like, and a cushion bracket 208 is attached to the upper surface of the cushion pipe B: 207 by welding or the like. A cushion 206 is mounted on the upper surface of the cushion bracket 208 for the user P who uses the transfer chair 100 to sit.

  An auxiliary gas spring 209 is disposed between the lower surface of the cushion pipe B: 207 and the base frame 103. The tip of the rod 2091 of the auxiliary gas spring 209 is connected to the lower surface of the cushion pipe B 207, and the lower end of the auxiliary gas spring 209 is fixed to the base frame 103. The auxiliary gas spring 209 always outputs a force in the direction of lifting the cushion pipe B: 207, that is, in the direction of lifting the cushion 206.

  When the user P seated on the cushion 206 operates the gas spring 210 to adjust the height of the cushion 206 while lifting his or her back somewhat, a force is applied to lift the cushion 206 from the auxiliary gas spring 209 As a result, the amount by which the user P lifts his / her waist somewhat can be reduced. Thereby, the burden on the user P when adjusting the height of the cushion 206 can be reduced.

  By using the gas spring 210 and the auxiliary gas spring 209 in combination, the output of the gas spring 210 is relatively small as compared with the case where the driving source for adjusting the height of the cushion 206 is configured by the gas spring 210 alone. The smaller external dimensions can be adopted. As a result, it is possible to further reduce the dimensions of the inner pipe 202 and the outer pipe 201 in which the gas spring 210 is mounted (the dimensions of each side in the cross section perpendicular to the paper in FIG. 2).

  When the user P is seated on the cushion 206, the weight of the user P is applied to the cushion 206. In this state, if there is no wheel 205, a portion where the inner pipe 202 is supported by the outer pipe 201 by the slider 220 acts as a fulcrum and a rotational moment is applied, and the lower end of the cushion pipe A: 204 is the one of the outer pipe 201. I will lean to the side. In addition, when the inner pipe 202 is slid up and down with respect to the outer pipe 201 with such a large moment load applied, a biased load is applied to the slider 220 and the movement of the slider 220 becomes worse. It may not be possible to slide in the direction smoothly.

  In addition, without the wheel 205, the user is seated on the cushion 206, and the cushion 206 is inclined and becomes uncomfortable, or the lower end of the cushion pipe A: 204 hits the outer surface of the outer pipe 201. There is a risk of scratching the outer surface.

  On the other hand, in the configuration shown in the present embodiment, since the outer peripheral surface of the wheel 205 attached to the cushion pipe A: 204 is in contact with the side surface of the outer pipe 201, the cushion pipe A: 204 rotates The moment is relaxed. As a result, the vertical movement of the cushion pipe A: 204, that is, the vertical movement of the cushion 206 can be smoothly performed.

  In the transfer chair 100 having the configuration as shown in FIGS. 1 and 2, the user P is seated on the cushion 206 in the orientation as shown in FIG. 3. That is, the user P sits on the cushion 206 in such a manner as to sandwich the support portion 20 in the crotch, and places both feet on the bottom board 106.

  Here, since the drive source for adjusting the height of the cushion 206 is configured by combining the gas spring 210 and the auxiliary gas spring 209, the user P does not bother when sandwiching the support 20 in the crotch. The outer pipe 201 can be slimmed down to an extent.

  When the user P transfers to the transfer care chair 100, the height of the cushion 206 is previously adjusted to a height at which the user P can easily sit. By placing the belt 306 around the back of the user P while the user P is seated on the cushion 206, the user P can be prevented from falling over the cushion 206.

  Next, when the user P is seated on the cushion 206 and held up near the left end portion of the lever 308 in FIG. 2, the portion on the right side of the pin 3082 of the lever 308 is centered on the pin 3082 Rotate downward. Thereby, the portion on the right side of the pin 3082 of the lever 308 abuts on the actuating piece 212 attached to the tip portion of the rod 211 of the gas spring 210, and pushes the actuating piece 212 into the inside of the rod 211.

  As the actuating piece 212 is pushed down, the gas spring 210 is released from the locked state, and the rod 211 of the gas spring 210 is lifted or raised according to the weight of the user P seated on the cushion 206 on the cushion 206. Go down. That is, when a load larger than the sum of the output of the gas spring 210 and the output of the auxiliary gas spring 209 is applied to the cushion 206, the cushion 206 descends, and the output of the gas spring 210 and the output of the auxiliary gas spring 209 When a load smaller than the total value is applied to the cushion 206, the cushion 206 is lowered.

  At this time, the wheel 205 rotatably attached near the lower end of the cushion pipe A: 204 is in contact with the outer pipe 201, and along with the movement of the cushion 206 in the vertical direction, the wheel 205 follows the outer pipe 201. Move while rotating. Thereby, the movement of the cushion 206 in the vertical direction is smoothly performed.

  On the other hand, when the user P releases the pulling up of the lever 308 (or when the user P releases his hand from the lever 308), the actuating piece 212 returns to the original position (in the state of FIG. The spring 210 is locked and the height of the cushion 206 is fixed.

  The operation of adjusting the height of the cushion 206 by operating the lever 308 may be performed by an assistant worker (not shown) even when the user P is seated on the cushion 206 or before the user P is seated. good.

  As shown in FIG. 3, with the user P seated on the cushion 206 and operating the lever 308 to adjust the height of the cushion 206, the assistant worker grasps the front grip 302 or the rear grip 304 and transfers it. The care chair 100 is moved to a target position, for example, to the toilet.

  At this time, the pair of casters 105 of the rear frame 104 is advanced such that the ends on both sides of the rear frame 104 of the transfer chair 100 sandwich the toilet bowl (not shown). The distal end portion of the rear frame 104 is widely open, so that the toilet bowl (not shown) can be easily pinched by the distal end portion of the rear frame 104, and the user P rests on the cushion 206 while sitting on the cushion 206. You can get closer to

  In this state, if the height of the cushion 206 adjusted before movement is different from the height of the toilet seat (not shown), the user P or the assistant operates the lever 308 to The lock state of the spring 210 is released, and the height of the cushion 206 is adjusted to the height of the toilet seat of the toilet bowl. Thus, by matching the height of the cushion 206 to the height of the toilet seat of the toilet bowl, the user P can transfer the cushion 206 to the toilet seat of the toilet bowl relatively easily.

  In addition, as shown in FIG. 4, the user P may be seated on the cushion 206 with the support portion 20 at the back with respect to the transfer care chair 100 according to the present embodiment. By the user P sitting on the cushion 206 in such an orientation, the transfer nursing chair 100 can be moved to a table (not shown) and can face the table while sitting on the cushion 206. It is possible to work at the table while sitting on the transfer chair 100 by adjusting the height of the cushion 206 to the table while adjusting the height of the cushion 206 while pulling up the lever 308 while facing the table.

  According to the present embodiment, the height of the cushion of the transfer chair can be adjusted with a relatively simple configuration, and the user P adjusts the height of the cushion according to the height of the transfer destination. Since transfer can be performed, transfer to or from the transfer chair can be performed relatively easily and safely.

  In addition, since the adjustment of the height of the cushion is performed by the gas spring installed inside the inner pipe, the space of the mechanism for adjusting the height of the cushion can be made smaller, and the transfer nursing chair Can be made smaller and lighter.

  In addition, the present embodiment is not limited to the method of use described above, and in a state where the user P stands, the front grip 302 is grasped from the direction opposite to the cushion 206 with respect to the column portion 20, By pushing forward and moving forward, the transfer chair 100 can be used as a walking aid. In this case, the user P can operate the lever 308 to adjust the height of the front grip 302.

  In the first embodiment, the height difference adjustment of the cushion 206 is described using the gas spring 210. However, in the present embodiment, the height adjustment of the cushion 206 is described using the motor as a drive source. Do.

  A cushion pipe B: 5207 is connected to the cushion pipe A: 5204 in a substantially perpendicular direction by welding or the like, and a cushion bracket 5208 is attached to the upper surface of the cushion pipe B: 5207 by welding or the like. A cushion 5206 is mounted on the upper surface of the cushion bracket 5208 for the user P who uses the transfer nursing chair 500 to sit.

  In such a configuration, the power supply from the battery 5403 to the controller 5404 is turned on by operating the on / off switching button 54051 of the remote control switch 5405. In this state, when the up button 54052 is pressed next, the controller 5404 controls the drive source 5401 to rotate the motor inside the drive source 5401 and raise the shaft 5402 (hereinafter, the direction of rotation of the motor at this time is Called the positive direction). While holding up the raise button 54052, the motor inside the drive source 5401 keeps rotating and the shaft 5402 keeps rising. When pressing the raising button 54052 is stopped, the rotation of the motor inside the drive source 5401 is stopped, and the shaft 5402 is stopped at that position.

  As the shaft 5402 ascends, the armrest bracket 5203 fixing the shaft 5402 ascends, and the cushion 5206 ascends. At this time, the inner pipe 5202 fixed to the armrest bracket 5203 can be smoothly raised by being guided by the outer pipe 5201 by the sliders 5220 disposed on the four surfaces around the inner pipe 5202.

  On the other hand, when the down button 54053 of the remote control switch 5405 is pressed, the controller 5404 controls the drive source 5401 to rotate the motor inside the drive source 5401 and lower the shaft 5402 (hereinafter, the motor rotation direction at this time) Is called the reverse direction). While continuing to press the lowering button 54053, the motor inside the drive source 5401 continues to rotate in the reverse direction, and the shaft 5402 continues to descend. When the depression of the lowering button 54053 is stopped, the rotation of the motor inside the drive source 5401 is stopped, and the shaft 5402 is stopped at that position.

  As the shaft 5402 is lowered, the armrest bracket 5203 fixing the shaft 5402 is lowered and the cushion 5206 is lowered. At this time, the inner pipe 5202 fixed to the armrest bracket 5203 can be smoothly raised by being guided by the outer pipe 5201 by the sliders 5220 disposed on the four surfaces around the inner pipe 5202.

Thus, the cushion 5206 can be raised or lowered by switching the direction of rotation of the motor inside the drive source 5401 with the remote control switch 5405 to drive the cushion 5206 up and down. It can be adjusted to any desired height.

  In the transfer care chair 500 having the configuration as shown in FIG. 5 and FIG. 6, the user P sits on the cushion 5206 in the orientation as described using FIG. 3 in the first embodiment. That is, the user P sits on the cushion 5206 in such a manner as to sandwich the support portion 520 in the crotch, and places the foot on the bottom board 5106. At this time, the height of the cushion 5206 is adjusted to a height at which the user P can easily sit. In a state where the user P is seated on the cushion 5206, the user P falls from the cushion 5206 by turning and attaching a belt (corresponding to the belt 306 of FIG. 1 described in the first embodiment) to the back of the user P. Can be prevented.

  Also in this embodiment, as described with reference to FIG. 3 and FIG. 4 in the first embodiment, transfer to the toilet seat of the toilet bowl (not shown) from the transfer care chair 500 or sitting on the transfer care chair 500 When facing the table as it is, the height of the cushion 5206 can be adjusted.

  The operation of the remote control switch 5405 may be performed by the user P of the transfer chair 500 while sitting on the cushion 5206, or by an assistant worker not shown.

  According to this embodiment, the height of the cushion of the transfer chair can be electrically adjusted with a relatively simple configuration, and the user adjusts the height of the cushion according to the height of the transfer destination. Since P can be transferred, transfer to or from the transfer chair, and adjustment of the height of the cushion can be performed relatively easily and safely.

  In addition, by attaching the battery of the electric part to the transfer care chair, the transfer care chair can be moved without requiring a cable for connecting the transfer care chair to the external power supply and without restricting the movement range.

  Further, the present embodiment is not limited to the method of use described above, and in the same manner as described in the first embodiment, from the direction opposite to the cushion 5206 with respect to the support 520 with the user P standing. By holding the front grip 5302 and pushing forward on the transfer chair 500, the transfer chair 500 can be used as a walking aid. In this case, the user P can operate the lever 5308 to adjust the height of the front grip 5302.
