  In this drip stand clamp 1400, when a user such as a nurse pulls up the operation wall portion 1421S of the rear clamp fitting 1420 upward, the shaft portion 1430 rotates in the insertion hole 1412X and is provided in the rear clamp fitting 1420. The protruding wall portion 1424 thus moved moves toward the recess wall 1413P side in the recess 1413 provided in the front clamp fitting 1410. Then, the rear support wall portion 1421 of the rear clamp fitting 1420 rotates about the axis X and moves upward. As a result, the engagement between the engagement claw portion 1416 of the front clamp fitting 1410 and the engagement wall portion 1421T of the rear clamp fitting 1420 is released.

  And since the back of the front clamp metal fitting 1410 is opened, the support | pillar part 94 is moved to the rear part of the front clamp metal fitting 1410 from back. A space SA (see FIG. 4) is formed between the front curved wall portion 1411 of the front clamp fitting 1410 and the rear support wall portion 1421 of the rear clamp fitting 1420. The support column 94 is disposed in the space SA. When the hand is released from the operation wall portion 1421S of the rear clamp fitting 1420, the rear clamp fitting 1420 moves downward by the biasing force of the biasing portion 1440.

  In this state, the separation distance between the rear surface 1411B of the front curved wall portion 1411 of the front clamp fitting 1410 and the front surface 1421F of the rear support wall portion 1421 of the rear clamp fitting 1420 is longer than the length in the front-rear direction of the column portion 94. . Therefore, the front surface of the support column 94 abuts against the front curved wall portion 1411 of the front clamp fitting 1410, and a space is provided between the rear surface of the support column portion 94 and the front support wall portion 1421 of the rear support wall portion 1421. While the portion SB is formed, the column portion 94 is held by the front clamp fitting 1410 and the rear support wall portion 1421.

  When the wall portion 1424P of the protruding wall portion 1424 provided on the rear clamp fitting 1420 abuts on the recess wall 1413P of the recess 1413 provided on the front clamp fitting 1410, the rotation of the rear clamp fitting 1420 stops. No further rotation.

(Guide frame)
Next, as shown in FIGS. 3 to 5, the guide frame 1500 includes a front-rear facing guide portion 1510 extending rearward from the lower portion of the bottom wall portion 1132 of the mounting body 1100 and a rear end from the rear end of the front-rear facing guide portion 1510.

  Furthermore, the guide frame 1500 includes a skew guide portion 1530 that gradually extends forward from the lower end of the rear vertical guide portion 1520 toward the inner side in the width direction of the wheelchair 2.

  Further, the guide frame 1500 includes a front vertical guide portion 1540 that extends upward from the front end of the skew guide portion 1530, and an inner side that extends forward from the upper end of the front vertical guide portion 1540 and has a tip attached to the lower portion of the bottom wall portion 1132. And a guide portion 1550.

  Next, a method of connecting the wheelchair 2 and the drip stand 3 in the medical equipment system 1 configured as described above will be described.

  First, the connecting pipe 1300 is rotated around the shaft portion 1131Z from the state where the second pipe portion 1330 is disposed along the left rear wheel 22 (see FIG. 2) as shown by a solid line in FIG. Then, the second pipe portion 1330 is rotated to a state where it is disposed between the left and right rear wheels 22, 22.

  Then, the user holds the support 94 of the drip stand 3 and moves the drip stand 3 forward from the rear of the wheelchair 2 between the pair of left and right rear wheels 22, 22.

  Here, when the front surface 91Z of one leg frame 91A is in contact with the rear vertical guide portion 1520 of the guide frame 1500, the leg frame which is arranged next to the leg frame 91A with the rear vertical guide portion 1520 as the center and faces forward. The drip stand 3 is rotated so that 91B moves forward. In the present embodiment, the drip stand 3 is rotated counterclockwise in plan view with the back vertical guide portion 1520 as the center.

  Then, the drip stand 3 is moved forward so that the leg frame 91B and the leg frame 91C adjacent to the leg frame 91B are disposed between the pair of rear wheels 22,22. In other words, the support column 94 is disposed in the rear space S1 (see FIG. 2) surrounded by the back surface of the back sheet 32A and the left and right grip portions 33A, 33A. Then, the user pulls the operation wall portion 1421S of the rear clamp fitting 1420 of the drip stand clamp 1400 upward and rotates it, and the post portion 94 of the drip stand 3 is moved from the rear of the front clamp fitting 1410 to the front clamp fitting 1410. Move to the back. Then, hands are released from the operation wall portion 1421S of the rear clamp fitting 1420, and the rear clamp fitting 1420 is rotated downward. In this way, the column portion 94 is held by the front clamp fitting 1410 and the rear support wall portion 1421, and the drip stand 3 is connected to the wheelchair 2 via the attachment 1000.

  In this state, the distal end of the leg frame 91B and the distal end of the leg frame 91C are arranged to face forward. Specifically, the end of the leg frame 91B faces between the front and the left. The tip of the leg frame 91C faces between the front and the right. The tip of the leg frame 91D adjacent to the leg frame 91C faces between the rear and the right. The front end of the leg frame 91E adjacent to the leg frame 91D faces rearward. The front end of the leg frame 91A faces between the rear and the left.

  On the other hand, when the user moves the drip stand 3 forward from the rear of the wheelchair 2 between the left and right rear wheels 22, 22 by holding the support column 94 of the drip stand 3, the leg frame 91 guides. When the tip of the leg frame 91B and the tip of the leg frame 91C are arranged so as to face forward as shown by a two-dot dashed line in FIG. 2 without coming into contact with the frame 1500, the drip stand 3 is left as it is. If it is moved forward, it is arranged at the connection position.

When removing the drip stand 3 from the wheelchair 2, a user such as a nurse pulls up the operation wall portion 1421 </ b> S of the rear clamp metal fitting 1420 so that the support 94 of the drip stand clamp 1400 is moved to the front clamp. It can be taken out between the metal fitting 1410 and the rear clamp metal fitting 1420.
In this way, the drip stand clamp 1400 of the attachment 1000 is detachably attached to the support column 94.

  Next, the operation | movement at the time of the medical equipment system 1 comprised as mentioned above climbing the level | step difference ahead of the advancing direction provided on the floor surface is demonstrated.

FIG. 11 is a side view for illustrating the operation of the drip stand clamp 1400 when the wheelchair 2 of the medical equipment system 1 rides on the floor level difference.
As shown in FIG. 11, when the wheelchair 2 rides up the step, a downward force is applied to the rear portion of the hand grip 33 or the tipping lever 31. As a result, the front side of the wheelchair 2 is lifted, the front wheel 21 climbs up the step, and the tipping lever 31 is inclined so as to go upward as it goes from the rear toward the front.

  When the tipping lever 31 is tilted forwardly, a force in a direction of tilting forwardly acts on the attachment 1000 connected to the tipping lever 31. Thereby, a backward force is applied to the support portion 94 of the drip stand 3 held by the attachment 1000 from the front curved wall portion 1411 of the front clamp fitting 1410. Thereby, the support | pillar part 94 moves back in space part SA. The drip stand clamp 1400 moves rearward and downward relative to the column portion 94 from the original position (solid line shown in FIG. 11) (two-dot chain line shown in FIG. 11). In this way, the drip stand clamp 1400 holds the support column 94 while varying the tilt angle of the tipping lever 31 and the support column 94 in the front-rear direction.

  When the front wheel 21 climbs the step and the rear wheel 22 and the drip stand 3 try to climb the step, the tipping lever 31 moves upward upward. At this time, the support column 94 of the drip stand 3 held by the attachment 1000 moves forward in the space SA (solid line shown in FIG. 11), and the rear wheel 22 and the drip stand 3 ride on the step.

  When the height of the step provided on the floor surface is high, when the wheelchair 2 rides on the step, the support column 94 of the drip stand 3 has a front curved surface of the front clamp fitting 1410. While abutting on the upper portion of the rear surface 1411B (see FIG. 9) of the wall portion 1411, the rear surface is greatly inclined so as to abut on the lower portion of the rear support wall portion 1421 (see FIG. 10) of the rear clamp fitting 1420. An upward force (force to lift the rear clamp metal fitting 1420) acts on the rear clamp metal fitting 1420 from the abutting support column 94. As a result, the rear clamp fitting 1420 is rotated and lifted, and the support column 94 can be moved further rearward than the space SA. In addition, since the rotation range of the rear clamp fitting 1420 is restricted, the support column 94 does not completely come out of the rear clamp fitting 1420.

  In addition, the drip stand clamp 1400 moves in the same manner as when the front wheel 21 of the wheelchair 2 rides on the step described above when going uphill from a substantially horizontal floor.

  On the other hand, when the wheelchair 2 descends the step, contrary to the above, the tipping lever 31 is tilted forward and a force is applied to the attachment 1000 to tilt downward.

  In the medical equipment system 1 configured as described above, in the first position, the inner protrusion 1351 of the pressing resin member 1340 is engaged between the outer protrusion 1161 and the outer protrusion 1162 of the support fitting 1140, and The inner protrusion 1352 of the pressing resin member 1340 is engaged between the outer protrusion 1163 and the outer protrusion 1164 of the support metal 1140. Therefore, when the wheelchair 2 and the drip stand 3 are not connected, the connection pipe 1300 of the attachment 1000 can be positioned and accommodated at the first position close to the left rear wheel 22.

  Further, the pressing resin member 1340 can be elastically deformed radially inward. Therefore, when the connecting pipe 1300 provided with the pressing resin member 1340 rotates, the pressing resin member 1340 is elastically deformed radially inward, and wear occurs between the pressing resin member 1340 and the support metal 1140. Therefore, durability can be improved.

  Further, at the first position as described above, the inner projections 1351 and 1352 are engaged between the outer projection 1161 and the outer projection 1162, and between the outer projection 1163 and the outer projection 1164, respectively. Since the pressing resin member 1340 is elastically deformed radially inward, for example, the engagement amount can be made larger than when the members corresponding to the support fitting and the pressing resin member are made of a rigid material. Therefore, the displacement of the pressing resin member 1340 from the first position can be suppressed.

  Further, since the shaft portion 1131Z is inserted into the shaft insertion hole 1151X formed in the support fitting 1140 and the holding resin member 1340, the shaft portion 1131Z can be arranged inside the support fitting 1140 and the holding resin member 1340. And a compact structure as a whole.

  Further, since the holding resin member 1340 is accommodated in the recess 1150 that is recessed in the direction of the axis O of the support fitting 1140, the overall structure can be reduced with the thickness in the direction of the axis O being suppressed. In addition, since the shaft portion 1131Z, the pressing resin member 1340, and the support metal fitting 1140 arranged in order from the center along the direction orthogonal to the axis O support the connection pipe 1300 via the shaft portion 1131Z, the connection is stably performed. The pipe 1300 can be supported.

  Further, the inner projections 1351 and 1352 projecting radially outward from the pressing resin member 1340 are respectively disposed between the outer projection 1161 and the outer projection 1162 projecting radially inward from the support fitting 1140. Immediately before the engagement between the protruding portion 1163 and the outer protruding portion 1164, the holding resin member 1340 having a cylindrical shape with a part cut in the circumferential direction is elastically deformed radially inward. Therefore, the outer protrusions 1161, 1162, 1163, 1164 and the inner protrusions 1351, 1352 can be easily engaged with each other without requiring a large force.

  Further, at the first position, the first locking wall portion 1156A of the support fitting 1140 and the side surface of the connection pipe 1300 are in contact with each other. Therefore, positioning of the pressing resin member 1340 at the first position can be made more reliable.

  Further, in the second position, the second locking wall portion 1156B of the bulging portion 1156 of the support metal fitting 1140, the inclined locking wall portion 1137 of the attachment body 1100, and the side surface of the connecting pipe 1300 abut. Therefore, the pressing resin member 1340 can be positioned at the second position.
