The vertical dimension of 411 is different. Next, from the front of a specific drip stand S (1), another drip stand S (() is placed so that the central frame 121 of another drip stand S (2) is parallel to the central frame 121 of this drip stand S (1). Approach 2). At this time, the leg frame 123 on the rear side of the other drip stand S (2) passes through the kicking space 1s4 formed below the front leg frame 122 of the specific drip stand S (1). Then, the handle 411 of the handle 4 of the other drip stand S (2) approaches or comes into contact with the support 2 of the specific drip stand S (1), and another drip is placed in front of the specific drip stand S (1). The stand S (2) can be nested.

  As described above, the drip stand S according to this embodiment is provided with an infusion hook 3 for supporting a support 2 on a movable leg base 1 and hanging an infusion pack P on the support 2. The leg base 1 is adjacent to the rear left caster 11 adjacent to the front left caster 11 and the front right caster 11 with respect to the distance w1 between the two adjacent casters 11 on the front left and right. The front standing space 1s1 opened forward is formed between the left and right casters 11 on the front side, and is set to be larger than the distance w2 between the rear right caster 11 and the front left caster 11. A left standing space 1s2 opened leftward and rearward is formed between the rear left caster 11 and rightward and rearward between the front right caster 11 and the rear right caster 11. Opened right Since the space 1s3 is formed, the at least four casters 11 are provided. Therefore, the stability is not impaired, and the user U can use the standing space 1s1. The drip stand S can be moved without difficulty from the front, and the user U can move the pointed stand S without difficulty from the left and right sides using the left standing space 1s2 or the right standing space 1s3. it can.

  That is, the leg base 1 of this embodiment includes four leg frames 122 and 123 in which casters 11 are provided at the end portions 122a and 123a, and other than the end portions 122a and 123a of the leg frames 122 and 123. Since the portion is located at least on the inner side of the straight line connecting the left caster 11 on the front side and the left caster 11 on the rear side, as schematically shown in FIG. The left standing space 1s2 in which the user U can stand and stand still or walk is formed inside a virtual triangle that connects the two in a plan view. In addition, the leftmost arrow in FIG. 10 indicates the traveling direction of the user U. Since the leg base 1 has such a structure, the user U can place a part of the leg in the left standing space 1 s 2, and put the hand on the column 2 or the handle 4 to place the drip stand S. The moving operation can be performed without difficulty. That is, since the user U can be closer to the support column 2 side than before, the drip stand S can be moved in a relatively stable posture. In particular, since the left standing space 1s2 is also opened rearward, the user U standing up and walking in the left standing space 1s2 may catch the heel on the rear leg frame 123. Can be reduced and walking with an unreasonable stride can be suppressed.

  Similarly, on the right side, the portions of the leg frames 122, 123 other than the front end portions 122a, 123a are located at least inside the straight line connecting the front right caster 11 and the rear right caster 11. Therefore, the right standing space 1s3 in which the user U stands up and can stand still or walk is formed inside a virtual triangle that connects the front and rear casters 11 and the column 2 in plan view. And the user U can arrange | position a part of leg in this right standing space 1s3, and can perform the operation | movement which moves the drip stand S by placing a hand on the support | pillar 2 or the handle | steering-wheel 4. . In particular, since the right standing space 1s3 is also opened rearward, the user U standing up and walking in the right standing space 1s3 may catch the heel on the rear leg frame 123. Can be reduced and walking with an unreasonable stride can be suppressed.

  Further, also on the front side, the portions other than the front end portion 122a of the front leg frame 122 are located at least inside the straight line connecting the front left caster 11 and the front right caster 11, FIG. As shown schematically, a standing space 1s1 before the user U can stand up and stand still or walk is formed inside a virtual triangle that connects the left and right casters 11 and the column 2 in plan view. More specifically, the front standing space 1s1 is formed in a trapezoidal space surrounded by the center frame 121 and the two front leg frames 122. In addition, the arrow at the left end in FIG. 11 indicates the traveling direction of the user U. Since the leg base 1 has such a structure, the user U can place a part of the leg in the previous standing space 1s1 and put the hand on the support column 2 or the handle 4 to place the drip stand S. The moving operation can be performed without difficulty. That is, since the user U can be closer to the support column 2 side than before, the drip stand S can be moved in a relatively stable posture.

  In the present embodiment, the leg base 1 has a center frame 121 extending in the left-right direction for supporting the support column 2, and two front leg frames 122 extending forward from both left and right ends of the center frame 121. Further, since the two rear leg frames 123 extending rearward from the middle portion of the center frame 121 are provided, the standing spaces 1s1, 1s2, 1s3 can be set relatively large. That is, since the center frame 121 extends in the left-right direction, the front standing space 1s1 can be set large in the left-right direction. In addition, while the front leg frame 122 extends from both ends of the center frame 121, the rear leg frame 123 extends from the middle portion of the center frame 121, so the left and right standing spaces 1s2, 1s3 are also very small. Never become.

  The leg base 1 has a front standing space 1s1 opened forward between two leg frames 122 supporting the left and right casters 11 on the front side, and a leg frame 122 supporting the left caster 11 on the front side. A left standing space 1s2 opened leftward and rearward is formed between the leg frame 123 supporting the rear left caster 11, and the leg frame 122 supporting the front right caster 11 and the rear frame Since the right standing space 1s3 opened to the right side and the rear side is formed between the leg frame 123 supporting the right caster 11, it is formed between the leg frames 122, 123. Further, the user U can approach the support column 2 more easily than before by using the standing spaces 1s1, 1s2, and 1s3.

  In particular, in the present embodiment, each leg frame 122, 123 has substantially the same width dimension from the proximal end side to the distal end side, so that the entire leg base 1 can be made a clean impression and used. The person U can easily stand in the standing spaces 1s1, 1s2, and 1s3. Moreover, since these leg frames 122 and 123 and the center frame 121 are made by integral molding of resin, unlike the conventional metal one, the touch when the user U's leg hits can be softened. A gentle impression can be given by the appearance of the drip stand S. Although the front-end | tip part 122a, 123a of each leg frame 122,123 has shown the aspect which attached the bumper for a collision prevention, you may not provide this bumper.

  Moreover, since the handle | steering-wheel 4 which can be respectively hold | gripped from the right-and-left both sides and the front side is provided in the support | pillar 2, the user U who stood in the left standing space 1s2, the right standing space 1s3, or the front standing space 1s1 It is easy to put a hand on the handle 4.

  Furthermore, the leg base 1 of the drip stand S of the present embodiment has four leg frames 122 and 123 provided with casters 11 at the end portions 122a and 123a, and two leg frames that support the casters 11 on the front side. 122 and two leg frames 123 that support the rear caster 11 are arranged in a C shape with the front end side widened in plan view, and the other leg frames 122 having the same structure are formed under the front leg frame 122. Since a space is formed so as to allow the leg frame 123 on the rear side of the drip stand S to pass therethrough, a plurality of drip stands S can be stacked in the horizontal direction.

  In addition, since the handle 4 that can be gripped from both the left and right sides and the front side is provided on the support column 2 so that the mounting position can be changed in the vertical direction, when the drip stands S are stacked in the horizontal direction, adjacent handles By changing the height positions of the four to each other, nesting can be performed without interference between the handles 4. Therefore, more drip stands S can be nested and nesting efficiency can be increased. In the present embodiment, the pitch between adjacent drip stands S is set to about 120 mm.
