Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the stand disclosed in Patent Document 1, when storing, since the upper surface of the leg of one stand abuts against the lower surface of the central part of another stand, there is a problem that the appearance of the upper surface of the leg deteriorates, such as dirt adhering to the upper surface of the leg, the coating on the upper surface of the leg peeling off, or the upper surface of the leg being damaged.

[0006] Therefore, the present invention has been made in view of the above circumstances, and provides a stand capable of suppressing the deterioration of the appearance of the upper surface of the leg.

Means for Solving the Problems

[0007] To achieve the above objective, the present invention employs the following means. In other words, the stand according to the present invention comprises legs that are installed on the floor surface, A stand comprising a support provided on a leg body for supporting an article, wherein the leg body is spaced apart from the floor surface and has a base for supporting the support, and a plurality of legs extending from the base toward the floor surface, the leg body has an insertion space formed between it and the floor surface into which the tip of the leg of another stand can be inserted from a width direction intersecting the extension direction of the leg, and the leg body has a contact portion into which the side surface of the leg of another stand can be brought into contact.

[0008] In a stand configured in this way, the tips of the legs of other stands are inserted into the insertion space of the leg body of one stand from the width direction. The sides of the legs of other stands abut against the contact points of the leg body of one stand. In a nesting configuration where at least a portion of the legs of other stands are positioned below the leg body of one stand, the sides of the legs of other stands abut against the contact points, thus suppressing deterioration of the appearance of the upper surface of the legs.

[0009] Furthermore, in the stand according to the present invention, the insertion space portion is provided below the leg portion and has a widthwise insertion space portion into which the leg portion of the other stand can be inserted from the widthwise direction of the leg portion, and the contact portion is provided on the base end side of the leg portion and has a first contact portion into which the side surface of the leg portion of the other stand inserted into the widthwise insertion space portion can be brought into contact.

[0010] In a stand configured in this way, the side surface of the leg of another stand contacts a first contact portion provided on the base end side of the leg of one stand. Therefore, movement of the leg of the other stand toward the base end in the extension direction relative to the leg of one stand is suppressed. Furthermore, since the tips of the legs of other stands are inserted deeply in the width direction into the widthwise insertion space below the legs of one stand, the storage space can be made even more compact.

[0011] Furthermore, in the stand according to the present invention, the surface of the first contact portion facing the widthwise insertion space portion may be formed to gradually extend toward the tip in the extension direction as it approaches the center of the leg portion in the widthwise direction.

[0012] In a stand configured in this way, the surface of the first contact portion facing the widthwise insertion space is formed to gradually extend towards the tip in the extension direction as it approaches the center in the widthwise direction of the leg. Therefore, when inserting the leg of another stand into the widthwise insertion space, the surface of the first contact portion facing the widthwise insertion space acts as a guide surface for the leg of the other stand, allowing for smooth nesting.

[0013] Furthermore, in the stand according to the present invention, the contact portion has a second contact portion provided on the tip side of the leg portion, and the widthwise insertion space portion may be formed between the first contact portion and the second contact portion.

[0014] In this configuration, the sides of the legs of other stands contact the first contact point located at the base end and the second contact point located at the tip end of the legs of one stand. Therefore, movement of the legs of other stands on either side in the extension direction relative to the legs of one stand is suppressed. Because the multiple stands are less likely to shift from one another in a nested state, stability can be increased when moving multiple stands together.

[0015] Furthermore, in the stand according to the present invention, the surface of the second contact portion facing the widthwise insertion space portion may be formed to gradually extend toward the base end in the extension direction as it approaches the center of the leg portion in the widthwise direction.

[0016] In a stand configured in this way, the surface of the second contact portion facing the widthwise insertion space is formed to gradually extend towards the base end in the extension direction as it approaches the center of the leg in the widthwise direction. Therefore, when inserting the leg of another stand into the widthwise insertion space, the surface of the second contact portion facing the widthwise insertion space acts as a guide surface for the leg of the other stand, allowing for smooth nesting.

[0017] Furthermore, in the stand according to the present invention, when the side surface of the leg of the other stand is in contact with the contact portion, a gap may be formed between the lower surface of the leg facing the widthwise insertion space and the tip of the leg of the other stand inserted into the insertion space.

[0018] In this configuration, when the stands are nested, a gap is formed between the lower surface of the leg facing the widthwise insertion space and the tip of the leg of the other stand. Therefore, the upper surface of the leg of the other stand does not come into contact with the leg of the first stand, further suppressing deterioration of the appearance of the upper surface of the leg.

[0019] Furthermore, in the stand according to the present invention, the other leg may be positioned below the base of the other stand, with the side surface of the leg of the other stand in contact with the contact portion of the leg of the other stand.

[0020] In this configuration, when the stands are nested, the other legs of one stand are positioned below the base of another stand. This prevents the legs of one stand from unintentionally coming into contact with the legs of another stand, and also allows for a more compact storage space.

[0021] Furthermore, in the stand according to the present invention, with the two legs of the other stand inserted into the widthwise insertion space of the two legs from one side in the widthwise direction, the two legs of the other stand may be in contact with the first contact portion and the second contact portion, thereby restricting their movement to the other side in the widthwise direction.

[0022] In the stand configured as described above, with the two legs of another stand inserted from one side in the width direction into the width-direction insertion spaces of the two legs, the two legs of the other stand abut against the first abutting portion and the second abutting portion, and the movement to one side in the width direction is restricted. Therefore, since the movement of each of the two legs to one side in the width direction is restricted, more reliable positioning can be achieved among a plurality of stands.

Effects of the Invention

[0023] According to the stand of the present invention, deterioration of the appearance of the upper surface of the leg can be suppressed.

[Modes for carrying out the invention]

[0025] The embodiments of the stand of the present invention will be described below with reference to Figures 1 to 6. The following embodiments represent one aspect of the present invention and are not limiting, and can be modified at will within the scope of the technical idea of ​​the present invention. In addition, in the following drawings, the scale of each structure differs from the actual structure in order to make each structure easier to understand.

[0026] In the following embodiments, an example in which the stand of the present invention is an intravenous drip stand will be described.

[0027] Figure 1 is a perspective view showing an intravenous drip stand 100 according to one embodiment of the present invention. As shown in Figure 1, the IV stand 100 is used in hospitals, nursing homes, and homes. The IV stand 100 comprises a leg body 1, a support 3, and an IV fluid suspension device 4.

[0028] (legs) The leg body 1 is installed on the floor surface F. The leg body 1 has a base 10 and a plurality of leg parts 20.

[0029] The lower end of the support 3 is connected to the upper part of the base 10. The base 10 supports the support 3. The base 10 is positioned spaced apart above the floor surface F. As shown in Figure 6, a space (insertion space) S1 is formed between the base 10 and the floor surface F.

[0030] Multiple legs 20 extend from the base 10 toward the floor surface F. In the illustrated example, five legs 20 are provided. However, it is sufficient to provide two or more legs 20, and the number can be set as appropriate.

[0031] As shown in Figure 3, the five legs 20 extend radially from the base 10. The lengths of the five legs 20 are approximately the same. In a plan view, the five legs 20 are arranged at equal intervals in the circumferential direction with respect to the base 10. The direction in which each leg 20 extends from the base 10 is called the extension direction. The direction perpendicular to the extension direction in each leg 20 is called the width direction. Note that the lengths of the five legs 20 do not have to be approximately the same. The five legs 20 do not have to be arranged at equal intervals in the circumferential direction with respect to the base 10.

[0032] As shown in Figure 1, a caster 21 is provided at the lower end of the extending tip of the leg portion 20. The caster 21 is placed on the floor surface F. The caster 21 is rotatable and can move on the floor surface F. Note that the lower part of the leg portion 20 does not necessarily have to have a caster 21.

[0033] As shown in Figure 5, the leg portion 20 has an upper wall portion 22 and a downward projection portion 23.

[0034] The upper wall portion 22 extends from the base portion 10. The upper surface 22u and lower surface 22d of the upper wall portion 22 are inclined with respect to the horizontal plane so that they gradually slope downward towards the tip in the extension direction. A boss portion 221 that protrudes downward is provided at the tip of the upper wall portion 22 in the extension direction. A caster 21 is attached to the boss portion 221.

[0035] As shown in Figures 1 and 3, the peripheral edge 22a of the upper wall portion 22 is formed to curve outward.

[0036] As shown in Figures 4 and 5, the downward projection 23 protrudes downward from the lower surface 22d of the upper wall portion 22. The downward projection 23 is located approximately in the center of the upper wall portion 22 in the width direction. The downward projection 23 is not provided at the ends of the upper wall portion 22 in the width direction.

[0037] The downward projection 23 has a base-side projection (contact portion, first contact portion) 24, a central projection 25, and a tip-side projection (contact portion, second contact portion) 26.

[0038] The base-side projection 24 is provided on the base end side in the extension direction of the leg portion 20. The base-side projection 24 is connected to the base portion 10.

[0039] As shown in Figure 5, the lower surface of the base end projection 24 has a first base end lower surface 241 and a second base end lower surface 242.

[0040] The first base-side lower surface 241 is connected to the lower surface 10d of the base 10. The first base-side lower surface 241 is formed to gradually slope downwards as it approaches the tip in the extension direction. The first base-side lower surface 241 may also be formed along a horizontal plane or to gradually slope upwards as it approaches the tip in the extension direction.

[0041] The second base-side lower surface 242 is connected to the tip side in the extension direction of the first base-side lower surface 241. The second base-side lower surface 242 is formed to gradually slope downward as it approaches the tip side in the extension direction. The inclination angle of the second base-side lower surface 242 with respect to the horizontal plane is gentler than the inclination angle of the first base-side lower surface 241 with respect to the horizontal plane. The second base-side lower surface 242 may also be formed along the horizontal plane or to gradually slope upward as it approaches the tip side in the extension direction. The inclination angle of the second base-side lower surface 242 with respect to the horizontal plane may be steeper than the inclination angle of the first base-side lower surface 241 with respect to the horizontal plane.

[0042] As shown in Figure 4, the tip-side surface of the base-side projection 24 in the extension direction is the base-side contact surface 243. The base-side contact surface 243 is formed to gradually extend towards the tip in the extension direction as it approaches the center in the width direction. The base-side contact surface 243 is formed on both sides of the base-side projection 24 in the width direction. The base-side contact surface 243 is formed to be pointed at the center in the width direction.

[0043] The central projection 25 is connected to the tip side in the extension direction of the base-side projection 24. As shown in Figure 5, the central lower surface 251, which is the lower surface of the central projection 25, is located above the second base-side lower surface 242. The central lower surface 251 is formed to gradually slope downwards as it approaches the tip side in the extension direction. The central lower surface 251 may also be formed along a horizontal plane or to gradually slope upwards as it approaches the tip side in the extension direction.

[0044] The tip-side projection 26 is connected to the tip side of the central projection 25 in the extension direction. The tip side of the tip-side projection 26 in the extension direction is connected to the boss portion 221. The tip-side lower surface 261, which is the lower surface of the tip-side projection 26, is formed to gradually slope downwards as it approaches the tip side in the extension direction. The tip-side lower surface 261 and the second base-side lower surface 242 are located below the central lower surface 251. The tip-side lower surface 261 may be formed along a horizontal plane or to gradually slope upwards as it approaches the tip side in the extension direction.

[0045] As shown in Figure 4, the base end surface of the tip-side projection 26 in the extension direction is the tip-side contact surface 263. The tip-side contact surface 263 is formed to gradually extend towards the base end in the extension direction as it approaches the center in the width direction. The tip-side contact surface 263 is formed on both sides of the tip-side projection 26 in the width direction. The tip-side contact surface 263 is formed to be pointed in the center in the width direction.

[0046] (Support) As shown in Figure 1, the support 3 is provided on the base 10 of the leg body 1. The support 3 has an outer support 31 and an inner support 32.

[0047] The outer support column 31 extends upward from the base 10. The outer support column 31 is formed in a hollow shape. The lower end of the inner support column 32 is slidably fitted into the upper part of the outer support column 31. Inside the support body 3, there is a locking mechanism (not shown) for fixing the relative position of the outer support column 31 and the inner support column 32. By releasing the locking mechanism, the relative position of the outer support column 31 and the inner support column 32 (the extension and retraction length of the support body 3) can be adjusted as appropriate. The support body 3 may be composed of a single piece and may have a configuration in which the vertical length cannot be changed.

[0048] A release operation sleeve 33 for releasing the locking mechanism is provided approximately in the middle of the inner support column 32 in the vertical direction. This release operation sleeve 33 is connected to the locking mechanism's release piece inside the inner support column 32 and is designed to release the locking mechanism when slid upward by an operator such as a nurse, and to re-lock the locking mechanism when slid downward.

[0049] A handle attachment 35 is mounted on the outer support column 31 so as to be adjustable in height. The handle attachment 35 has an annular handle body 36 and a disc-shaped tray 37 positioned below the handle body 36. In plan view, the handle body 36 and the tray 37 are positioned eccentrically from the support 3. In plan view, the tray 37 is smaller than the handle body 36, and the outer edge of the tray 37 is positioned inward from the outer edge of the handle body 36. Items C such as cups can be placed on the tray 37. Alternatively, in plan view, the handle body 36 and the tray 37 may be positioned around the support 3 so as not to be eccentric from the support 3. In another case, in plan view, the tray 37 is larger than the handle body 36, and the outer edge of the tray 37 is positioned outside the outer edge of the handle body 36.

[0050] (IV fluid hanging device) The IV fluid suspension device 4 is attached to the upper end of the inner support column 32 of the support body 3. The IV fluid suspension device 4 has a roughly cylindrical suspension body 41 and a plurality of hooks 42 provided on the outer surface of the suspension body 41. The suspension holes of the IV fluid pack P can be engaged with the hooks 42. The shape of the suspension body 41 can be set as appropriate.

[0051] Next, a state in which multiple IV stands 100 are nested will be described. In this embodiment, nesting means that at least a portion of the legs 20 of another IV stand 100 is positioned below at least one of the multiple legs 20 of one IV stand 100.

[0052] As shown in Figure 2, an IV stand (one IV stand) 100 in which the two legs 20 of another IV stand 100 are positioned below the two legs 20 of the first IV stand 100 is designated as IV stand 100X. An IV stand (another stand) 100 in which the two legs 20 are positioned below the two legs 20 of IV stand 100X is designated as IV stand 100Y.

[0053] The five legs 20 of the IV stand 100X are designated as legs 20X1, 20X2, 20X3, 20X4, and 20X5 in a clockwise direction in a plan view. The five legs 20 of the IV stand 100Y are designated as legs 20Y1, 20Y2, 20Y3, 20Y4, and 20Y5 in a clockwise direction in a plan view.

[0054] A portion of the leg 20Y5 of the IV stand 100Y is positioned below the leg 20X1 of the IV stand 100X. A portion of the leg 20Y4 of the IV stand 100Y is positioned below the leg 20X3 of the IV stand 100X. A portion of the leg 20X2 of the IV stand 100X is positioned below the base 10 of the IV stand 100Y.

[0055] As shown in Figures 3 and 4, the tip (referred to as the first tip) 201 of the leg 20Y5 of the IV stand 100Y is positioned below the middle portion in the extension direction of the leg 20X1 of the IV stand 100X. The first tip 201 of the leg 20Y4 of the IV stand 100Y is positioned below the middle portion in the extension direction of the leg 20X3 of the IV stand 100X. Below the base 10 of the IV stand 100Y, the portion (referred to as the second tip) 202 of the leg 20X2 of the IV stand 100X, extending from the middle portion in the extension direction to the tip, is positioned.

[0056] As shown in Figure 5, below a portion of the leg portion 20, an insertion space S2 is formed into which the leg portion 20 of another stand 100 can be inserted from the width direction. The insertion space S2 is formed below the portion of the leg portion 20 that does not have a base-side projection 24 or a tip-side projection 26.

[0057] As shown in Figure 4, the insertion space S2 includes the lower spaces S21 and S22 on both sides in the width direction of the base end projection 24, the lower space S23 of the central projection 25, the lower spaces S24 and S25 on both sides in the width direction of the central projection 25, and the lower spaces S26 and S27 on both sides in the width direction of the tip end projection 26.

[0058] Spaces S23, S24, and S25 are formed on the tip side in the extension direction of the base end projection 24 and on the base end side in the extension direction of the tip end projection 26, extending in the width direction of the leg portion 20. Spaces S23, S24, and S25 correspond to the widthwise insertion spaces of the claims.

[0059] As shown in Figure 5, the leg portion 20Y5 of the IV stand 100Y is inserted into the spaces S23, S24, and S25 of the insertion space S2 of the leg portion 20X1 of the IV stand 100X. One end face 203 of the leg portion 20Y5 in the width direction is in contact with the base end contact surface 243 of the base end projection 24 of the leg portion 20X1. The other end face 204 of the leg portion 20Y5 in the width direction is in contact with the tip end contact surface 263 of the tip end projection 26 of the leg portion 20X1.

[0060] A gap S3 is formed between the lower surface of the insertion space S2 in the leg portion 20X1, facing the spaces S23, S24, and S25, that is, between the central lower surface 251 of the central projection 25 of the leg portion 20Y5 and the upper surface 22u of the first tip portion 201 of the leg portion 20Y5.

[0061] The height H1 from the lowest point of the upper surface 22u of the first tip portion 201 of the leg portion 20Y5 to the floor surface F is higher than the height H2 from the highest point of the second base-side lower surface 242 of the base-side projection 24 of the leg portion 20X1 to the floor surface F and the height H3 from the highest point of the tip-side lower surface 261 of the tip-side projection 26 of the leg portion 20X1 to the floor surface F. Therefore, the first tip portion 201 of the leg portion 20Y5 is prevented from penetrating below the second base-side lower surface 242 of the base-side projection 24 of the leg portion 20X1 and below the tip-side lower surface 261 of the tip-side projection 26.

[0062] As shown in Figure 3, the legs 20Y5 and 20Y4 of the IV stand 100Y are arranged so that they gradually move further apart from each other as they move away from the base 10. The legs 20Y5 and 20Y4 of the IV stand 100Y are inserted from one side in the width direction below the legs 20X1 and 20X3 of the IV stand 100X, respectively. The sides 203 and 204 of the legs 20Y5 and 20Y4 are in contact with the base end contact surface 243 and the tip end contact surface 263 of the legs 20X1 and 20X3, respectively. As a result, the legs 20Y5 and 20Y4 of the IV stand 100Y are not inserted any deeper into the insertion space S2, and their movement to the other side in the width direction relative to the spaces S23, S24, and S25 of the insertion space S2 is restricted.

[0063] As shown in Figures 3 and 6, the second tip 202 of the leg portion 20X2 of the IV stand 100X is positioned below the base 10 of the IV stand 100Y.

[0064] As shown in Figure 3, when the IV stands 100X and 100Y are nested, the handle body 36 of the handle attachment 35 of IV stand 100X and the handle body 36 of the handle attachment 35 of IV stand 100Y are not positioned on top of each other. The handle bodies 36 are positioned either touching each other as shown in the illustrated example, or with a gap between them.

[0065] In the IV stand 100 configured in this way, the first tip portions 201 of the legs 20Y5 and 20Y4 of the IV stand 100Y are inserted from one side in the width direction into the spaces S23, S24, and S25 of the insertion space S2 of the legs 20X1 and 20X3 of the IV stand 100X. The side surfaces 203 and 204 of the legs 20Y5 and 20Y4 of the IV stand 100Y abut against the base end projection 24 and the tip end projection 26 of the legs 20X1 and 20X3 of the IV stand 100X. In a nesting configuration where at least a portion of the legs 20 of IV stand 100Y is positioned below at least one of the multiple legs 20 of IV stand 100X, the legs 20 contact the base end projection 24 and the tip end projection 26 only on their sides 203 and 204, thus suppressing deterioration of the appearance of the upper surface 22u of the legs 20.

[0066] Furthermore, the side surface 203 of the leg portion 20 of the IV stand 100Y abuts against the base end projection 24 provided on the base end side of the leg portion of the IV stand 100X. Therefore, movement of the leg portion 20 of the IV stand 100Y toward the base end in the extension direction relative to the leg portion 20 of the IV stand 100X is suppressed.

[0067] Furthermore, the tip 201 of the leg portion 20 of the IV stand 100Y is inserted from the width direction into the spaces S23, S24, and S25 of the leg portion 20 of the IV stand 100X. Since the spaces S23, S24, and S25 are formed across the width direction of the leg portion 20, the leg portion 20 of the IV stand 100Y is inserted deeply in the width direction below the leg portion 20 of the IV stand 100X. Therefore, since the leg portion 20 of the IV stand 100Y can be inserted deeply in the width direction below the leg portion 20 of the IV stand 100X, the storage space can be made even more compact.

[0068] Furthermore, the base-side contact surface 243 of the base-side projection 24, which faces the spaces S23, S24, and S25, is formed to gradually extend towards the tip in the extension direction as it approaches the center in the width direction of the leg portion 20. Therefore, when inserting the leg portion 20 of the IV stand 100Y into the spaces S23, S24, and S25, the base-side contact surface 243 of the base-side projection 24 acts as a guide surface for the leg portion 20 of the IV stand 100Y, allowing for smooth nesting.

[0069] Furthermore, the sides 203 and 204 of the legs 20 of the IV stand 100Y abut against the base-side projection 24 and the tip-side projection 26 provided on the base end side and tip end side of the legs 20 of the IV stand 100X, respectively. Therefore, movement of the legs 20 of the IV stand 100Y in the extension direction relative to the legs 20 of the IV stand 100X is suppressed. In a nested state, multiple IV stands 100 are less likely to shift from one another, thus improving stability when moving multiple IV stands 100 together.

[0070] Furthermore, the tip-side contact surface 263 of the tip-side projection 26, which faces the spaces S23, S24, and S25, is formed to gradually extend towards the base end in the extension direction as it approaches the center in the width direction of the leg portion 20. Therefore, when inserting the leg portion 20 of the IV stand 100Y into the spaces S23, S24, and S25, the tip-side contact surface 263 of the tip-side projection 26 acts as a guide surface for the leg portion 20 of the IV stand 100Y, allowing for smooth nesting.

[0071] Furthermore, in the nested state, a gap S3 is formed between the central lower surface 251 of the central protrusion 25 facing the insertion space S2 in the leg portion 20 and the tip portion 201 of the leg portion 20 of the IV stand 100Y. Therefore, the upper surface 22u of the leg portion 20 of the IV stand 100Y does not come into contact with the leg portion 20 of the IV stand 100X, and deterioration of the appearance of the upper surface 22u of the leg portion 20 can be further suppressed.

[0072] Furthermore, in the nested configuration, the legs 20x2 of the IV stand 100X are positioned below the base 10 of the IV stand 100Y. This prevents the legs 20 of the IV stand 100X from unintentionally coming into contact with the legs 20 of the IV stand 100Y, and also allows for a more compact storage space.

[0073] Furthermore, when the two legs 20Y5 and 20Y4 of the IV stand 100Y are inserted into the spaces S23, S24, and S25 of the two legs 20X1 and 20X3 of the IV stand 100X from one side in the width direction, the two legs 20Y5 and 20Y4 of the IV stand 100Y come into contact with the base end projection 24 and the tip end projection 26, restricting their movement to the other side in the width direction. Therefore, since the movement of each of the two legs to one side in the width direction is restricted, positioning can be performed more reliably with multiple stands.

[0074] Furthermore, spaces S23, S24, and S25 are formed between the base-side projection 24 and the tip-side projection 26 of the leg portion 20, extending in the width direction of the leg portion 20. Therefore, the leg portion 20 of another stand 100 can be inserted between the base-side projection 24 and the tip-side projection 26 from both sides in the width direction.

[0075] (Variation 1) Next, a stand according to Modification 1 of one embodiment of the present invention will be described mainly with reference to Figure 7. In the modifications described below, components corresponding to the embodiments shown above may be denoted by the same reference numerals and their descriptions may be omitted.

[0076] As shown in Figure 7, in the IV stand 100A, the base-side projection (contact portion, first contact portion) 24A is provided only on the base side in the extension direction of the central projection 25. The tip-side projection (contact portion, second contact portion) 26A is provided only on the tip side in the extension direction of the central projection 25. The tip-side projection 26A is not connected to the boss portion 221.

[0077] In the IV stand 100A configured in this way, the first tip portions 201 of the legs 20Y5 and 20Y4 of the IV stand 100Y are inserted from the width direction into the insertion space S2 of the legs 20X1 and 20X3 of the IV stand 100X. The sides 203 and 204 of the legs 20Y5 and 20Y4 of the IV stand 100Y abut against the base-side projection 24A and the tip-side projection 26A of the legs 20X1 and 20X3 of the IV stand 100X. In a nesting state in which at least a portion of the legs 20 of the IV stand 100Y is positioned below at least one of the multiple legs 20 of the IV stand 100X, the sides 203 and 204 of the legs 20 abut against the base-side projection 24A and the tip-side projection 26A, thus preventing deterioration of the appearance of the upper surface 22u of the legs 20.

[0078] (Modification 2) Next, a stand according to a modified example 2 of one embodiment of the present invention will be described mainly with reference to Figure 8.

[0079] As shown in Figure 8, in the IV stand 100B, the downward projection (contact portion) 23B that protrudes downward from the upper wall portion 22 is formed continuously from the base portion 10 to the boss portion 221. The areas on both sides of the downward projection 23B in the width direction, below the upper wall portion 22, are designated as insertion spaces S2A. The insertion spaces S2A have spaces S21, S22, S24, S25, S26, and S27. Spaces S21, S24, and S26 are formed continuously in the extension direction on one side of the downward projection 23B in the width direction. Spaces S22, S25, and S27 are formed continuously in the extension direction on the other side of the downward projection 23B in the width direction.

[0080] The side surface 206 of the first tip 201 of the legs 20Y4, 20Y5 of the IV stand 100Y is inserted from one side of the legs 20X3, 20X1 of the IV stand 100X and abuts against the side surface 205 in the width direction. The side surface 206 of the first tip 201 of the legs 20Y4, 20Y5 is the surface facing the tip in the extension direction of the legs 20Y4, 20Y5. As a result, the movement of the IV stand 100Y to the other side in the width direction of the legs 20X3, 20X1 of the IV stand 100X is restricted.

[0081] In the IV stand 100B configured in this way, the first tip portions 201 of the legs 20Y5 and 20Y4 of the IV stand 100Y are inserted from the width direction into the insertion space S2A of the legs 20X1 and 20X3 of the IV stand 100X. The side surfaces 206 of the legs 20Y5 and 20Y4 of the IV stand 100Y abut against the downward projections 23B of the legs 20X1 and 20X3 of the IV stand 100X. In a nesting state in which at least a portion of the legs 20 of the IV stand 100Y is positioned below at least one of the multiple legs 20 of the IV stand 100X, the side surfaces 206 of the legs 20 abut against the downward projections 23B, thus suppressing deterioration of the appearance of the upper surface 22u of the legs 20.

[0082] (Variation 3) Next, a stand according to a modified example 3 of one embodiment of the present invention will be described mainly with reference to Figure 9.

[0083] As shown in Figure 9, the IV stand 100C comprises a base 10C and four legs 20C. An insertion space S1 is formed below the base 10C. A contact portion 27 that protrudes downward is provided at the lower part of the base 10C. The legs 20C of the IV stand 100Y are inserted below the base 10C of the IV stand 100X. The side surface 207 of the tip of the leg 20C of the IV stand 100Y is in contact with the contact portion 27 of the base 10C. The side surface 207 of the tip of the leg 20C of the IV stand 100Y is the surface facing the tip in the extension direction of the leg 20C.

[0084] In the IV stand 100C configured in this way, the leg portion 20C of the IV stand 100Y is inserted into the insertion space S1 formed below the base portion 10C of the leg portion 20C of the IV stand 100X. The side surface 207 of the leg portion 20C of the IV stand 100Y abuts against the contact portion 27 of the leg portion 20C of the IV stand 100X. In a nesting state where at least a portion of the leg portion 20C of the IV stand 100Y is positioned below the base portion 10C of the IV stand 100X, it is the side surface 207 of the leg portion 20C that abuts against the contact portion 27, thus preventing deterioration of the appearance of the upper surface 22u of the leg portion 20.

[0085] (Modification 4) Next, a stand according to a modified example 4 of one embodiment of the present invention will be described mainly with reference to Figure 10.

[0086] As shown in Figure 10, the IV stand 100D comprises a base 10D and four legs 20D. The lower part of each leg 20D is provided with a contact portion 28 that protrudes downward. The legs 20D of the IV stand 100Y are inserted below the legs 20D of the IV stand 100X. The side surface 208 of the tip of the leg 20D of the IV stand 100Y is in contact with the contact portion 28 of the leg 20D. The side surface 208 of the tip of the leg 20D of the IV stand 100Y is the surface facing the tip in the direction of extension of the leg 20D.

[0087] In the IV stand 100D configured in this way, the leg portion 20D of the IV stand 100Y is inserted into an insertion space formed below the base portion 10D of the leg portion 20D of the IV stand 100X. The side surface 208 of the leg portion 20D of the IV stand 100Y abuts against the contact portion 28 of the leg portion 20D of the IV stand 100X. In a nesting state where at least a portion of the leg portion 20D of the IV stand 100Y is positioned below the leg portion 20D of the IV stand 100X, it is the side surface 208 that abuts against the contact portion 28 of the leg portion 20D, thus suppressing deterioration of the appearance of the upper surface 22u of the leg portion 20.
