Description

[Technical field]

[0001] The present invention relates to a conveying fixture and a cart. [Background technology]

[0002] In various facilities such as medical facilities, public facilities, and offices, transport fixtures are sometimes used to transport items. The transport fixtures are equipped with storage fixtures capable of storing items and casters that are provided below the storage fixtures and can run on the floor surface (for example, see Patent Document 1 below). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2000-168561 A Summary of the Invention [Problem to be solved by the invention]

[0004] The transport fixtures described above are used on the premise that they are used to transport goods. In other words, when the purpose is only to store or display goods within a facility, fixtures without casters (storage fixtures) can be used.

[0005] However, the required number of transport fixtures and storage fixtures may increase or decrease depending on the situation. In this case, since transport fixtures are generally more expensive than storage fixtures, introducing more transport fixtures than the required number poses the problem of increased introduction costs. In addition, designing dedicated transport fixtures and dedicated storage fixtures separately may lead to increased manufacturing costs and reduced manufacturing efficiency.

[0006] The present invention provides a transport fixture and cart that can reduce manufacturing costs and improve manufacturing efficiency while keeping introduction costs down. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention employs the following aspects. (1) A transport fixture according to one embodiment of the present invention comprises a cart having a base, a plurality of casters provided on the base, and a protrusion protruding upward from the base, capable of running on a floor surface, and a storage fixture capable of switching between a freestanding state in contact with the floor surface and a mounted state mounted on the cart, and the underside of the storage fixture has a recess into which the protrusion is inserted when in the mounted state.

[0008] According to this aspect, the storage fixture can be movably supported via the cart by simply inserting the protrusion into the recess. In other words, the mounted state and the freestanding state can be switched simply by the presence or absence of the cart. This allows the number of transport fixtures and storage fixtures to be increased or decreased depending on the required number of each. As a result, there is no need to introduce more transport fixtures than necessary, and introduction costs can be reduced. In addition, since the same storage fixtures are used for both the mounted and freestanding states, manufacturing costs can be reduced and manufacturing efficiency can be improved compared to cases where the transport fixtures and the storage fixtures are designed separately.

[0009] (2) In the transport fixture relating to the above aspect (1), it is preferable that the base portion comprises a first frame facing each other in a first direction intersecting the vertical direction and extending in a second direction intersecting the first direction when viewed from the vertical direction, and a second frame extending in the first direction and connecting the middle portions of the facing first frames in the second direction. According to this aspect, unlike the case where the base portion is formed in a frame shape, the second frame is disposed at a position recessed in the second direction from both ends of the first frame. This makes it possible to suppress interference between the feet of a user and the cart when, for example, an article is put in or taken out of a storage fixture from the second direction or a transport fixture is pushed from the second direction. As a result, workability can be improved.

[0010] (3) In the transport fixture relating to the above aspect (2), it is preferable that the second frame is provided singly in the center of the first frame in the second direction, and the length of the second frame in the first direction is longer than the length of the first frame in the second direction. According to this aspect, the material cost of the base portion can be reduced compared to a case in which the second frames are provided on both ends of the first frame, such as when the base portion is formed in a frame shape.

[0011] (4) In the transport fixture relating to aspect (2) or (3) above, it is preferable that the protrusions are provided at both ends of the first frame in the second direction. According to this aspect, the storage fixture and the dolly can be connected at both ends of the transport fixture in the second direction, which makes it easier to ensure the stability of the transport fixture.

[0012] (5) In a transport fixture relating to any one of the aspects (2) to (4) above, it is preferable that, in a plan view, the first frame protrudes outward in the first direction further than the storage fixture in the mounted state, and the casters are each provided on a portion of the first frame that protrudes outward in the second direction from the storage fixture. According to this aspect, the contact point between the transport fixture and the floor surface can be positioned outside the storage fixture in the second direction, thereby allowing the transport fixture to be stably contacted with the floor surface.

[0013] (6) In the transport fixture relating to any one of the above aspects (2) to (5), it is preferable that the base portion includes an intermediate frame extending in the second direction so as to intersect the second frame at the center of the second frame in the first direction, and the casters are provided at the intersection of the intermediate frame with the second frame. According to this aspect, the load applied from the storage fixture to the intermediate frame is supported on the floor surface via the casters. This suppresses bending of the base portion and allows the dolly to stably support the storage fixture.

[0014] (7) In the transport fixture relating to any one of the above aspects (1) to (6), it is preferable that the storage fixture is in contact with the floor surface in the freestanding state, while having a grounding portion that is supported by the base portion in the mounted state. According to this aspect, the common grounding portion is grounded in both the free-standing state and the mounted state, thereby simplifying the configuration.

[0015] (8) A cart according to one embodiment of the present invention is a cart capable of carrying a storage fixture, and includes a base portion, a plurality of casters provided on the base portion, and a protrusion protruding upward from the base portion and adapted to be inserted into a recess opening into the underside of the storage fixture. According to this aspect, the protrusion can be inserted through the recess in the storage fixture to connect the dolly to the storage fixture. This allows the storage fixture in a free-standing state to be used as a transport fixture after the dolly and the storage fixture are firmly connected. Effect of the Invention

[0016] According to each of the above aspects, it is possible to reduce manufacturing costs and improve manufacturing efficiency while suppressing implementation costs. [Brief description of the drawings]

[0018] Next, an embodiment of the present invention will be described with reference to the drawings. In the embodiments and modifications described below, the same reference numerals may be used to designate corresponding configurations, and the description may be omitted. In the following description, expressions indicating relative or absolute arrangements, such as "parallel," "orthogonal," "center," and "coaxial," not only strictly indicate such arrangements, but also indicate a state in which the two surfaces are relatively displaced with an angle or distance to the extent that the same function is obtained. In this embodiment, "facing" does not only mean a case in which the orthogonal directions (normal directions) of the two surfaces are aligned with each other, but also includes a case in which the orthogonal directions intersect with each other.

[0019] [Transportation fixture 1] Fig. 1 is a perspective view of the transportation fixture 1. Fig. 2 is an exploded perspective view of the transportation fixture 1. Fig. 3 is a front view of the transportation fixture 1. Fig. 4 is a plan view of the transportation fixture 1. 1 to 4 is used to transport items within a facility. The transport fixture 1 includes a storage fixture 10, an operation unit 11, and a cart 12.

[0020] <Storage fixture 10> The storage fixture 10 is a rectangular parallelepiped shape in which items are stored. The storage fixture 10 is rectangular in plan view. In the following description, the long side of the storage fixture 10 is the front-rear direction (arrow FR indicates the front) and the short side is the left-right direction (arrow LH indicates the left) in plan view. In addition, in the front-rear and left-right directions, the direction approaching the center of the storage fixture 10 may be referred to as the inside, and the direction away from the center of the storage fixture 10 may be referred to as the outside. However, the plan view shape of the storage fixture 10 is not limited to a rectangle, and may be a polygonal shape other than a rectangle, a circle, or the like.

[0021] As shown in FIG. 1, the storage fixture 10 comprises a base frame 21, a lower panel 22, an upper panel 23, and a plurality of tray modules 24.

[0022] <Base frame 21> The base frame 21 constitutes the exterior of the storage fixture 10. The base frame 21 is formed in a rectangular parallelepiped frame shape. Specifically, the base frame 21 includes corner supports 31, a central support 32, a lower frame portion 33, an upper frame portion 34, a lower connecting member 35, and an upper connecting member 36.

[0023] The corner supports 31 constitute the respective corners, in a plan view, of the base frame 21. The corner supports 31 are a first front support 31A, a second front support 31B, a first rear support 31C, and a second rear support 31D. The first front support pillar 31A constitutes a corner portion located on a first side in the left-right direction among front corner portions of the base frame 21 in a plan view. The second front support 31B constitutes a corner portion located on a second side in the left-right direction among the front corner portions of the base frame 21 in a plan view. The first rear support 31C constitutes a corner portion located on a first side in the left-right direction among rear corner portions of the base frame 21 in a plan view. The second rear support 31D constitutes a corner located on the second side in the left-right direction among the rear corners of the base frame 21 in a plan view. Since each corner support 31 has the same configuration, the following description will explain the details of each corner support 31 using the first front support 31A as an example.

[0024] FIG. 5 is a cross-sectional view corresponding to the line VV in FIG. 5, the first front support 31A is formed in a C-shape (C-channel) that opens toward the inside in the left-right direction (toward the center of the storage fixture 10) in a plan view. That is, the openings (for example, openings 45, 50 described later) of the first front support 31A and the second front support 31B face each other in the left-right direction, and the openings of the first rear support 31C and the second rear support 31D face each other in the left-right direction.

[0025] The first front support 31A includes an outer wall portion 41, an inner wall portion 42, a connecting wall portion 43, and a protruding wall portion 44. The outer wall portion 41 extends in the up-down direction with the thickness direction being the front-to-rear direction. The surface (front surface) of the outer wall portion 41 constitutes the outer surface (front surface) of the base frame 21 (storage fixture 10). The outer wall portion 41 has an outer wall through hole 41a that penetrates the outer wall portion 41 in the front-to-rear direction. A plurality of the outer wall through holes 41a are formed at intervals in the up-down direction. The inner wall portion 42 is disposed facing the outer wall portion 41 on the inside in the front-rear direction with respect to the outer wall portion 41. The inner wall portion 42 extends parallel to the outer wall portion 41 with the front-rear direction being the thickness direction. The inner wall portion 42 is formed with inner wall through holes 42a penetrating the inner wall portion 42 in the front-rear direction. The inner wall through holes 42a are formed in the inner wall portion 42 at positions facing each of the outer wall through holes 41a in the front-rear direction. However, the pitch and shape of the outer wall through holes 41a and the inner wall through holes 42a may be different from each other.

[0026] The connecting wall portion 43 connects the outer edges of the outer wall portion 41 and the inner wall portion 42 in the left-right direction. The connecting wall portion 43 extends in the up-down direction with the left-right direction being the thickness direction. The surface of the connecting wall portion 43 (the surface facing outward in the left-right direction) constitutes the outer surface of the base frame 21 (the surface facing the first side in the left-right direction). The boundary portion between the connecting wall portion 43 and the outer wall portion 41, and the boundary portion between the connecting wall portion 43 and the inner wall portion 42 are rounded.

[0027] The protruding walls 44 are formed on the inner ends in the left-right direction of the outer wall 41 and the inner wall 42. The protruding walls 44 extend in a direction approaching each other in the front-rear direction. Between each of the protruding walls 44, an opening 45 is formed that opens inward in the left-right direction. The first front support 31A can be accessed inside the first front support 31A through the opening 45.

[0028] 2, the central pillars 32 are a first central pillar 32A provided between the first front pillar 31A and the first rear pillar 31C, and a second central pillar 32B provided between the second front pillar 31B and the second rear pillar 31D. Since each central pillar 32 has the same configuration, the following description will explain the details of each central pillar 32 using the first central pillar 32A as an example.

[0029] 5, the first central pillar 32A is formed in a C-shape that opens inward in the left-right direction in plan view, similar to the corner pillar 31. Specifically, the first central pillar 32A includes a pair of opposing walls 46, 47, a connecting wall 48, and a protruding wall 49. The opposing walls 46, 47 face each other with the thickness direction being the front-rear direction. A plurality of opposing wall through holes 46a, 47a are formed in each of the opposing walls 46, 47 at intervals in the up-down direction. Each opposing wall through hole 46a, 47a is formed at a position facing the outer wall through hole 41a and the inner wall through hole 42a in the front-rear direction.

[0030] The connecting wall portion 48 connects the outer edges of the opposing walls 46, 47 in the left and right direction. The protruding walls 49 extend in a direction approaching each other in the front-rear direction from the inner ends in the left-right direction of the opposing walls 46, 47. An opening 50 that opens inward in the left-right direction is formed between each protruding wall 49. The first central support 32A can be accessed through the opening 50.

[0031] As shown in Fig. 1, the lower frame portion 33 and the upper frame portion 34 are each formed into a rectangular frame shape in a plan view by combining a plurality of plate materials. Specifically, as shown in Fig. 2, the lower frame portion 33 includes a front short side plate 33a, a rear short side plate 33b, and a long side plate 33c. The front short-side plate 33a bridges between the lower ends of the front pillars 31A and 31B. The front short-side plate 33a is fixed to the inner wall portions 42 of the front pillars 31A and 31B with screws or the like. The rear short-side plate 33b bridges between the lower ends of the rear supports 31C, 31D. The rear short-side plate 33b is overlapped with the inner wall portions 42 of the rear supports 31C, 31B from the inside in the front-to-rear direction and fixed to the inner wall portions 42 with screws or the like. The long-side plate 33c bridges between the lower ends of adjacent columns in the front-rear direction. The long-side plate 33c is fixed to the connecting walls 43, 48 with screws or the like in a state where it is overlapped with the connecting wall 43 of the first front column 31A and the connecting wall 48 of the first central column 32A from the outside in the left-right direction.

[0032] As shown in FIG. 1, like the lower frame portion 33, the upper frame portion 34 includes a front short side plate 34a, a rear short side plate 34b, and a long side plate 34c. The front short-side plate 34a bridges between the upper ends of the front pillars 31A, 31B. The front short-side plate 34a is fixed to the inner wall portions 42 of the front pillars 31A, 31B with screws or the like. The rear short-side plate 34b spans between the upper ends of the rear pillars 31C, 31D. The rear short-side plate 34b is overlapped with the inner wall portions 42 of the rear pillars 31C, 31B from the inside in the front-to-rear direction and fixed to the inner wall portions 42 with screws or the like. The long-side plate 34c bridges between the lower ends of adjacent columns in the front-rear direction. The long-side plate 34c is fixed to the connecting walls 43, 48 with screws or the like in a state where it is overlapped with the connecting wall 43 of the first front column 31A and the connecting wall 48 of the first central column 32A from the outside in the left-right direction.

[0033] The lower connecting member 35 bridges between the lower ends of the central pillars 32A, 32B. The lower connecting member 35 is a plate material whose thickness direction is in the front-to-rear direction. The lower connecting member 35 connects the opposing walls 46 of the central pillars 32A, 32B to each other and the opposing walls 47 to each other. The lower connecting member 35 is fixed to the opposing wall 46 with screws or the like, for example, in a state where it is overlapped with the opposing wall 46 from the front.

[0034] The upper connecting member 36 bridges between the upper ends of the central pillars 32A, 32B. Similar to the lower connecting member 35, the upper connecting member 36 is a plate material whose thickness direction is in the front-to-rear direction. The upper connecting member 36 connects the opposing wall portions 46 of the central pillars 32A, 32B to each other and the opposing wall portions 47 to each other. The upper connecting member 36 is fixed to the opposing wall portions 46 with screws or the like, for example, in a state where it is overlapped with the opposing wall portions 46 from the front.

[0035] The lower plate 22 constitutes the bottom wall of the storage fixture 10. The lower plate 22 is fitted into a space surrounded by the lower frame portion 33 and the lower connecting member 35. The upper plate 23 constitutes the top wall of the storage fixture 10. The upper plate 23 is fitted into the space surrounded by the upper frame portion 34 and the upper connecting member 36.

[0036] In the storage fixture 10, the space surrounded by the base frame 21, the lower plate 22, and the upper plate 23 functions as a storage section 51 capable of storing items. The storage section 51 is open on both sides in the front-to-rear direction between the front columns 31A, 31B and between the rear columns 31C, 31D. The storage section 51 is also open on both sides in the left-to-right direction between adjacent columns in the front-to-rear direction (for example, between the first front column 31A and the first central column 32A). In this case, the surface of the inner wall portion 42 of the corner column 31 and the surface of the opposing wall portion 46 of the central column 32 face the storage section 51.

[0037] In the storage section 51, a space surrounded by the front pillars 31A, 31B and the central pillars 32A, 32B constitutes a first storage space 51a. In the storage section 51, a space surrounded by the rear pillars 31C, 31D and the central pillars 32A, 32B constitutes a second storage space 51b.

[0038] <Tray Module 24> The tray modules 24 are provided in a plurality of stages in the vertical direction in each of the storage spaces 51a, 51b. In the following description, one tray module 24 provided in the first storage space 51a will be described as an example. The tray module 24 includes a pair of tray rails (a front rail 61 and a rear rail 62 ) and a tray 63 .

[0039] The front rail 61 is bridged between the front pillars 31A and 31B. Specifically, the front rail 61 is attached to the front pillars 31A and 31B by being engaged with one selected from the plurality of inner wall through holes 42a or a plurality of adjacent inner wall through holes 42a. The rear rail 62 is bridged between the central posts 32A, 32B at the same height as the corresponding front rail 61. Specifically, the rear rail 62 is attached to the central posts 32A, 32B by engaging with one selected from the multiple opposing wall through holes 46a or with multiple adjacent opposing wall through holes 46a. That is, each of the front rails 61, 62 is configured to be able to change its height within the first storage space 51a by changing the through hole 42a, 46a to be engaged.

[0040] The tray 63 is supported between the rails 61, 62 corresponding to each other in the front-rear direction so as to be slidable in the left-right direction. The tray 63 includes a tray main body 63a and a flange portion 63b. The tray body 63a is formed in a box shape that opens upward. Articles can be stored in the tray body 63a through the upper end opening. That is, in the storage fixture 10 of this embodiment, articles can be stored in the storage section 51 through the tray 63. The flange portion 63b protrudes outward from the entire circumference of the upper opening edge of the tray body 63a. The portion of the flange portion 63b that protrudes forward from the tray body 63a is supported by the front rail 61. The portion of the flange portion 63b that protrudes rearward from the tray body 63a is supported by the rear rail 62.

[0041] The tray 63 is configured to be slidable in the left-right direction by each flange portion 63b sliding on the corresponding rails 61, 62. That is, the tray 63 is configured to be able to be pulled out through the first storage space 51a between the first front support column 31A and the first central support column 32A, or between the second front support column 31B and the second central support column 32B.

[0042] <Operation unit 11> The operating unit 11 is held by the user when moving the transport fixture 1. In this embodiment, the operating units 11 are attached to the front and rear of the storage fixture 10. Since each operating unit 11 has the same configuration, the following explanation will be given using the operating unit 11 attached to the front of the storage fixture 10 as an example. Note that the operating unit 11 is not a required component.

[0043] The operation unit 11 is formed in a U-shape that opens upward when viewed from the front. The operation unit 11 includes a vertical grip portion 71 and a horizontal grip portion 72. The vertical gripping portions 71 are attached to the outer wall portions 41 of the front pillars 31A and 31B, respectively. The horizontal gripping portion 72 bridges the lower ends of the vertical gripping portions 71 in the left-right direction.

[0044] <Cart 12> 2, the cart 12 is configured to be able to run on a floor surface F with the storage fixture 10 mounted thereon. The cart 12 includes a cart frame 100, protrusions 101a to 101c, and casters 102a to 102c.

[0045] The bogie frame 100 is configured by combining a plurality of rods. Specifically, the bogie frame 100 includes a front frame 110, a rear frame 111, a connecting frame 112, and an intermediate frame 113.

[0046] The front frame 110 and the rear frame 111 extend parallel to each other in the left-right direction while facing each other in the front-rear direction. The left-right lengths of the front frame 110 and the rear frame 111 are equal to each other. In this embodiment, the front frame 110 and the rear frame 111 are longer than the left-right length of the base frame 21. The connecting frame 112 bridges between the left-right central portions of the front frame 110 and the rear frame 111. The length of the connecting frame 112 in the front-rear direction is longer than the lengths of the front frame 110 and the rear frame 111 in the left-right direction.

[0047] The intermediate frame 113 is provided in the middle of the connecting frame 112 in the front-rear direction. The intermediate frame 113 extends in the left-right direction so as to intersect with the connecting frame 112. The length of the intermediate frame 113 in the left-right direction is shorter than the length of the front frame 110 and the rear frame 111 in the left-right direction. Therefore, both ends of the front frame 110 and the rear frame 111 in the left-right direction protrude outward in the left-right direction relative to the intermediate frame 113. In this embodiment, the intermediate frame 113 has a length equal to the length of the base frame 21 in the left-right direction. The bogie frame 100 may be configured such that a plurality of intermediate frames 113 are provided at intervals in the front-rear direction in the connecting frame 112, or may be configured such that no intermediate frame 113 is provided. In addition, the dimensions of each of the frames 110 to 113 can be changed as appropriate.

[0048] The protruding portions 101a to 101c are for connecting the dolly 12 and the storage fixture 10. The protruding portions 101a to 101c protrude upward from the dolly frame 100. Specifically, the protruding portions 101a to 101c are a front protruding portion 101a, a rear protruding portion 101b, and a middle protruding portion 101c.

[0049] The front protrusions 101a protrude upward from both ends of the front frame 110 in the left-right direction. In a plan view, each front protrusion 101a is formed in a C-shape that opens toward the inside in the left-right direction. Of each front protrusion 101a, a first front protrusion 101a1 located on a first side in the left-right direction is inserted into the first front support 31A through an opening at the lower end of the first front support 31A. Of each front protrusion 101a, a second front protrusion 101a2 located on a second side in the left-right direction is inserted into the second front support 31B through an opening at the lower end of the second front support 31B.

[0050] The rear protrusions 101b protrude upward from both ends of the rear frame 111 in the left-right direction. Each rear protrusion 101b, like the front protrusions 101a, is formed in a C-shape opening toward the inside in the left-right direction in a plan view. Of each rear protrusion 101b, a first rear protrusion 101b1 located on a first side in the left-right direction is inserted into the first rear column 31C through a lower end opening of the first rear column 31C. Of each rear protrusion 101b, a second rear protrusion 101b2 located on a second side in the left-right direction is inserted into the second rear column 31D through a lower end opening of the second rear column 31D.

[0051] FIG. 6 is a cross-sectional view taken along line VI-VI in FIG. 5 and 6, when each of the protrusions 101a-101c is inserted into the corresponding support pillar, the lower end opening edge of the support pillar is supported on the upper surface of the cart frame 100. Therefore, when the storage fixture 10 is mounted on the cart 12, the lower end opening edge of the support pillar functions as a grounding portion that is in contact with the cart frame 100. In addition, each of the protrusions 101a-101c abuts against the inner surfaces of the corresponding support pillars 31A-31D, 32A, 32B, thereby restricting movement of the storage fixture 10 relative to the cart 12 in the front-rear and left-right directions.

[0052] Each of the protrusions 101a to 101c is fastened to the corresponding support pillars 31A to 31D, 32A, and 32B by a fastening member 115 such as a screw. Specifically, the fastening member 115 penetrates the corresponding support pillar from the outside in the left-right direction, and then is fixed to the protrusion.

[0053] 2, the casters 102a to 102c protrude downward from the cart frame 100. Each of the casters 102a to 102c is configured to be rotatable about a rotation axis O along the vertical direction, and is also configured to be rotatable about a rotation axis along the floor surface F. The cart 12 is in contact with the floor surface F via the casters 102a to 102c.

[0054] The casters 102a to 102c include a front caster 102a, a rear caster 102b, and a middle caster 102c.

[0055] The front casters 102a are provided at both left and right ends of the front frame 110. At least the rotation axis O of the front casters 102a is located outside the front protrusion 101a in the left and right direction. Therefore, in the mounted state, the rotation axis O of the front caster 102a is located outside the storage fixture 10 (base frame 21) in the left and right direction. The rear casters 102b are provided at both left and right ends of the rear frame 111. At least the rotation axis O of the rear casters 102b is located outside the rear protrusion 101b in the left and right direction. Therefore, in the mounted state, the rotation axis O of the rear caster 102b is located outside the storage fixture 10 (base frame 21) in the left and right direction. Note that the entire casters 102a, 102b may be located outside the storage fixture 10 in the left and right direction.

[0056] The intermediate caster 102c is provided at an intersection between the intermediate frame 113 and the connecting frame 112. Therefore, the rotation axis O of the intermediate caster 102c is located between the intermediate protruding portions 101c in the left-right direction.

[0057] FIG. 7 is a perspective view of the storage fixture 10 in a free-standing state. The transport fixture 1 of this embodiment can be switched between a mounted state in which the storage fixture 10 is mounted on a cart 12 as shown in Figure 1, and a free-standing state in which the storage fixture 10 is directly placed on the floor surface F as shown in Figure 7. In order to move the transport fixture 1 in the loaded state shown in Fig. 1, a person stands in front or behind the transport fixture 1 and grasps the operating unit 11. In this state, the transport fixture 1 can be moved (forward, backward, or swiveling) by pushing or pulling the transport fixture 1. In addition, in order to take in or take out an article in the loaded state, the tray 63 is pulled out, for example, from the first side in the left-right direction while the conveying fixture 1 is stopped.

[0058] On the other hand, in the free-standing state shown in Fig. 7, the storage fixture 10 is not attached to the cart 12 and is grounded to the floor surface F via each support. This allows the storage fixture 10 to be grounded to the floor surface F without the cart 12. In other words, the lower edge of each support also functions as a grounding part that is grounded to the floor surface F. The support may be grounded to the floor surface F via a cap fitted into the lower end opening. In the free-standing state, to take in or take out an article, the tray 63 is pulled out, for example, from the first side in the left-right direction, in the same manner as in the mounted state.

[0059] In this manner, in this embodiment, the bottom surface of the storage fixture 10 is configured to have recesses (openings at the bottom ends of the posts) into which the protrusions 101a to 101c are inserted when the storage fixture 10 is mounted. According to this configuration, the storage fixture 10 can be movably supported via the dolly 12 simply by inserting the protrusions 101a-101c into the openings at the bottom ends of the supports. In other words, the mounted state and the freestanding state can be switched simply by the presence or absence of the dolly 12. This allows the number of transport fixtures 1 and storage fixtures 10 to be increased or decreased depending on the required number of each. As a result, there is no need to introduce more transport fixtures 1 than necessary, and introduction costs can be reduced. In addition, since the same storage fixture 10 is used for both the mounted state and the freestanding state, manufacturing costs can be reduced and manufacturing efficiency can be improved compared to when the transport fixture 1 and the storage fixture 10 are designed separately.

[0060] In the transport fixture 1 of this embodiment, the cart frame (base portion) 100 is configured to include a front frame 110 and a rear frame 111 (first frame) that extend in the left-right direction (second direction) while facing each other in the fore-and-aft direction (first direction), and a connecting frame (second frame) 112 that connects the left-right middle portions of the front frame 110 and the rear frame 111. According to this configuration, unlike when the cart frame 100 is formed in a frame shape, the connecting frame 112 is disposed at a position recessed in the left-right direction from both ends of the front frame 110 and the rear frame 111. This makes it possible to prevent interference between the feet of a user and the cart frame 100, for example, when taking items in and out of the storage fixture 10 from the left and right, or when pushing the transport fixture 1 from the left and right. As a result, workability can be improved.

[0061] In the transport fixture 1 of this embodiment, the length of the connecting frame 112 in the front-rear direction is longer than the length of the front frame 110 and the rear frame 111 in the left-right direction. With this configuration, the material costs of the bogie frame 100 can be reduced compared to when connecting frames 112 are provided at both ends of the front frame 110 and the rear frame 111, as in the case where the bogie frame 100 is formed in a frame shape.

[0062] In the conveying fixture 1 of this embodiment, the protrusions 101a, 101b are provided at both ends in the left-right direction of the front frame 110 and the rear frame 111, respectively. According to this configuration, the storage fixture 10 and the cart 12 can be connected at both left and right ends of the transport fixture 1. This makes it easier to ensure the stability of the transport fixture 1.

[0063] In the transport fixture 1 of this embodiment, the pivot axes of the front casters 102a and the rear casters 102b are positioned outside the storage fixture 10 in the left-right direction. According to this configuration, the contact point between the transport fixture 1 and the floor surface F can be positioned outside in the left-right direction with respect to the storage fixture 10. This allows the transport fixture 1 to be stably contacted with the ground.

[0064] In the transport fixture 1 of this embodiment, the intermediate caster 102c is provided at the intersection of the connecting frame 112 and the intermediate frame 113. According to this configuration, the load applied from the storage fixture 10 to the intermediate frame 113 is supported on the floor surface F via the intermediate casters 101c. This suppresses bending of the cart frame 100, and allows the storage fixture 10 to be stably supported by the cart 12. In addition, the intermediate casters 101c are positioned at positions recessed in the left-right direction from both ends of the front frame 110 and the rear frame 111. This suppresses interference between the feet of a user and the intermediate casters 101c, for example, when items are put in and taken out of the storage fixture 10 from the left and right, or when the transport fixture 1 is pushed from the left and right.

[0065] In the transport fixture 1 of this embodiment, the lower end opening edge of the support pillar of the storage fixture 10 is configured to be in contact with the floor surface F when in a free-standing state, while functioning as a grounding portion supported by the trolley frame 100 when mounted. According to this configuration, in both the freestanding state and the mounted state, the ground contact portion of the storage fixture 10 is set at the lower end opening edge of the support, thereby simplifying the configuration.

[0066] The dolly 12 of this embodiment can be connected to the storage fixture 10 by inserting the protrusions 101a to 101c through the lower end openings of the supports of the storage fixture 10. This allows the dolly 12 and the storage fixture 10 to be firmly connected, and the freestanding storage fixture 10 can be used as the transport fixture 1.
