  In order to solve the above problems, a foldable rack of the present invention is a foldable rack that accommodates a desired article, and a base material and a pair of fixed frames that are arranged to face the upper surface of the base material, A rack body having a holding member that holds each of the fixed frames on the upper surface of the base member in a tiltable state; and an insertion frame that connects between opposing sides of the pair of fixed frames arranged to face each other. The insertion frame has two or more connecting struts each having both ends formed in the insertion portion, and the fixed frame has an insertion frame receiving portion into which the insertion portion is inserted. The pair of fixed frames arranged opposite to each other are connected by inserting the insertion portions at both ends of the connection column into the insertion frame receiving portions of the fixed frames arranged opposite to each other. It is characterized by.

  Preferably, the length of the inserted portion is different between the insertion portion at one end of the insertion frame and the insertion portion at the other end.

  Preferably, at least one of the fixed frame and the insertion frame is formed in a fence shape, and a periphery of a space for housing the desired article is defined by a member configured in the fence shape. It is characterized by.

  Preferably, at least one of the fixed frame and the insertion frame is partially or entirely formed in a plate surface form, and the member having a portion configured in the plate surface form A space around a desired article is defined.

  According to the present invention, there is no rattling, that is, the rigidity is high and strong, so that the contents can be safely transported, the articles can be easily carried in and out, and the work of transporting the articles is efficient. A folding rack that can be performed well can be provided.

A folding rack according to an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view showing the overall configuration of a foldable rack 1 of the present embodiment.
As shown in FIG. 1, the foldable rack 1 includes a rack body 10 and two insertion frames 20.
The rack body 10 includes a pallet part (base material) 110, a corner metal fitting (holding member) 120, a stacking metal fitting 130, a floor plate 140, and a fixed frame 150, which are integrated.

  The pallet part 110 of the rack body 10 is a support part that forms the lowermost part of the foldable rack 1, and is a carrier for the foldable rack 1. In this embodiment, the pallet unit 110 is formed by joining steel square pipes (cylindrical members having a rectangular cross section) by welding or the like. A lift hole 111 into which a forklift claw portion is inserted is formed on the side surface of the pallet portion 110.

The corner fitting 120 is a support having an L-shaped cross section that is joined to the four corners of the pallet portion 110.
The corner fitting 120 supports the fixed frame 150 so as to be movable and rotatable. The corner metal fittings 120 are erected at the four corners of the pallet part 110, respectively, but two corner metal parts 150 are erected on the both sides of the two fixed frames 150 arranged opposite to the upper surface of the pallet part 110. By 120, it clamps so that movement and rotation are possible.

  Each corner fitting 120 is arranged by bending one plate-like member or joining two plate-like members so that the two plate surfaces are orthogonal to each other, and in a columnar shape having an L-shaped cross section. It is a formed member. It is fixed to one plate surface of each corner metal fitting 120 and to the mutually opposing surfaces of the two corner metal fittings 120 sandwiching one fixed frame 150, that is, the surfaces in contact with the left and right side surfaces of the fixed frame 150. A rail 121 into which a protrusion 151 formed so as to protrude outward is formed at the lower part of both side surfaces of the frame 150. Since the protrusions 151 on the lower side surfaces of each fixed frame 150 are fitted into the rails 121 of the corner metal fittings 120 on both sides, the lower side portion of the fixed frame 150 is movable along the rail 121. 150 can be rotated about the position of the protrusion 151 as a rotation axis, and the fixed frame 150 cannot be detached from the corner bracket 120 and is integrated with the rack body 10.

  The plate surface of each corner bracket 120 on which the rail 121 is not formed, that is, the surface in contact with the front frame portion of the fixed frame 150 is when the fixed frame 150 is erected and the folding rack 1 is assembled. The rotation of the fixed frame 150 in the outer direction is restricted. Thus, when the folding rack 1 is assembled, the fixed frame 150 is erected in a state perpendicular to the upper surface of the pallet unit 110.

  Moreover, the corner metal fitting 120 becomes a support column when the folding rack 1 is folded and stacked. At the lower part of the corner bracket 120, a stacking bracket 130 that is fitted to the upper surface of the corner bracket 120 is disposed. When the folded folding racks 1 are sequentially stacked, the folding rack is stacked on top. The stacking metal fittings 130 of the rack 1 are sequentially fitted and stacked on the upper part of the corner metal fitting 120 of the foldable rack 1 placed below.

  As described above, the stacking bracket 130 is a receiving member in which a concave portion into which the upper portion of the corner bracket 120 is fitted is formed on the lower surface, and is a lower portion of each of the four corners of the pallet portion 110 of the foldable rack 1, The four corner fittings 120 are disposed at the lower portions. When folding and stacking the folding racks 1, the folding racks 1 are sequentially stacked so that the stacking brackets 130 are fitted on the corner brackets 120 of the folding racks 1 placed below. I will do it. Thereby, even if the folding racks 1 are stacked in multiple stages, the folding rack 1 can be prevented from shifting, and the folding rack 1 can be safely and easily handled in the folded state. It can be transported.

  The floor board 140 is disposed on the upper surface of the pallet unit 110 and defines the lower surface of the luggage storage space of the foldable rack 1. That is, a desired luggage is placed on the floor board 140. In the present embodiment, the floor plate 140 is a steel plate member, and is joined to the upper surface of the pallet unit 110 by welding.

  The fixed frame 150 defines the side surface of the accommodation space of the folding rack 1 together with the insertion frame 20 described later. That is, it is installed so as to surround the periphery of the upper surface of the pallet unit 110 together with the insertion frame 20, thereby accommodating a desired luggage therein. Two fixed frames 150 are arranged opposite to each other on a pair of opposite sides of the upper surface of the pallet unit 110.

FIG. 2 is a front view of the fixed frame 150 as viewed from the inside of the folding rack 1.
The fixed frame 150 is a member formed in a fence shape as shown in the figure by joining steel square pipes (cylindrical members having a rectangular cross section) by welding or the like.

  Protrusions 151 are formed on the lower portions of both side surfaces of the fixed frame 150 so as to protrude outward. As described above, the protrusions 151 are fitted into the rails 121 of the corner fittings 120 disposed on both sides of the fixed frame 150. As a result, the lower side portion of the fixed frame 150 is movable along the rail 121, and the fixed frame 150 is rotatable about the position of the protrusion 151 as a rotation axis. Further, the fixed frame 150 cannot be detached from the corner fitting 120 and is integrated with the rack body 10.

  The lower side of the fixed frame 150, that is, the projecting portion 151 is positioned at the lowermost part of the rail 121 when the fixed frame 150 is erected on the pallet unit 110 and the foldable rack 1 is assembled. In addition, when the fixed frame 150 is tilted upward and the foldable rack 1 is folded, the height (thickness) of the insertion frame 20 placed in order on the pallet unit 110, or the difference It moves upward along the rail 121 by an amount corresponding to the height (thickness) of the recessed frame 20 and the other fixed frame 150. As described above, since the lower side portion of the fixed frame 150 can move in the vertical direction along the rail 121 within a predetermined range, when the folding rack 1 is folded, the insertion frame 20 or the like is placed under the tilted fixed frame 150. Even if placed, the fixed frame 150 can be folded horizontally on the pallet unit 110.

  Further, the rotation of the fixed frame 150 is such that the upper surface of the pallet unit 110 is tilted from the direction perpendicular to the upper surface of the pallet unit 110 to the upper surface of the pallet unit 110 with the protrusion 151 of the fixed frame 150 as a rotation axis. It is possible in a range up to a direction substantially parallel to. The outward rotation from the direction perpendicular to the top surface of the pallet portion 110 of the fixed frame 150 is restricted by the plate surface of the corner bracket 120 where the rail 121 is not formed.

The first insertion frame receiver in which the insertion parts 203 and 205 of the insertion frame 20 are received on the surfaces inside the rack of the support columns 153 and 154 on both sides of the fixed frame 150, that is, the insertion parts 203 and 205 are inserted. A portion 155 and a second insertion frame receiving portion 156 are installed.
The first insertion frame receiving portion 155 is formed at two locations on the upper and lower sides of the rack inner side surface of the support column 153 on one side of the fixed frame 150, and the second insertion frame receiving portion Reference numeral 156 is formed at two locations on the upper side and the lower side of the rack inner side surface of the column 154 on the other side of the fixed frame 150.

  The upper end surfaces of the insertion frame receiving portions on the upper side of the first insertion frame receiving portion 155 and the second insertion frame receiving portion 156 are arranged at the same height in the height direction of the fixed frame 150, and The upper end surfaces of the insertion frame receiving portions on the lower side of the first insertion frame receiving portion 155 and the second insertion frame receiving portion 156 are also arranged at the same height in the height direction of the fixed frame 150. The positions of the upper end surfaces of the first and second insertion frame receiving portions 155 and 156 are the insertion frames arranged between the fixed frames 150 arranged to face each other when the folding rack 1 is assembled. The position of the connecting strut 201 provided at the top and bottom of 20 is defined. Therefore, the interval between the upper insertion frame receiving portions 155 and 156 and the lower insertion frame receiving portions 155 and 156 of each of the insertion frame receiving portions 155 and 156 is the same as that of the two connecting columns 201 of the insertion frame 20. Corresponds to the interval.

  As will be described later, the lengths of the insertion portion 203 and the insertion portion 205 formed at both ends of the connection column 201 in the insertion frame 20 are different. In this embodiment, the length of the 1st insertion frame receiving part 155 and the 2nd insertion frame receiving part 156 is the length of the 1st insertion part 203 or the 2nd insertion part 205 inserted, respectively. The length corresponding to the length, that is, the length in which the first insertion portion 203 or the second insertion portion 205 is just accommodated. In the present embodiment, the first insertion frame receiving portion 155 is formed to be longer than the second insertion frame receiving portion 156.

  Note that the functions of the first insertion frame receiving portion 155 and the second insertion frame receiving portion 156 will be described in detail when the insertion frame 20 is described.

  The insertion frame 20 defines the side surface of the storage space of the foldable rack 1 together with the fixed frame 150 described above. That is, when the two insertion frames 20 are attached to the rack body 10 so as to connect the opposing sides of the two fixed frames 150 arranged opposite to each other, the foldable rack 1 is placed inside. It is in an assembled state that can accommodate luggage.

FIG. 3 is a front view of the insertion frame 20, and FIG. 4 is a diagram schematically showing a usage pattern when the insertion frame 20 is installed in the rack body 10.
The insertion frame 20 has two upper and lower connecting struts 201 that are horizontally disposed, and a vertical strut 211 that connects the two connecting struts 201 at a predetermined interval. It is a member formed like a fence.
Like the fixed frame 150, the insertion frame 20 is formed by joining steel cylindrical pipes (cylindrical members having a circular cross section) by welding or the like.

At both ends of the two connecting struts 201, a first insertion portion 203 that is orthogonal to the connecting strut 201 and extends downward (a direction that is downward in the vertical direction when the insertion frame 20 is attached to the rack body 10). And the 2nd insertion part 205 is formed.
When the foldable rack 1 is used, the first insertion portion 203 and the second insertion portion 205 are connected to the first insertion portion of the fixed frame 150 arranged to face each other, as shown in FIG. By inserting each into the frame receiving portion 155 and the second insertion frame receiving portion 156, the opposite sides of the two fixed frames 150 are connected to each other by the two insertion frames 20, and the folding rack 1 is Assembled.
Further, when the folding rack 1 is folded, the insertion frame 20 is lifted and the first insertion portion 203 and the second insertion portion 205 of the insertion frame 20 are moved to the first insertion frame receiving portion of the fixed frame 150. By detaching from the 155 and the second insertion frame receiving portion 156, the insertion frame 20 is separated from the rack body 10, and the fixing frame 150 is foldable in the rack body 10.

  Moreover, in this embodiment, the 2nd insertion part 205 is formed shorter than the 1st insertion part 203. FIG. In such a configuration, when the insertion frame 20 is lifted to such an extent that the insertion of the second insertion portion 205 into the second insertion frame receiving portion 156 is removed, as shown in FIG. The state where the first insertion portion 203 is inserted into the first insertion frame receiving portion 155 is maintained. Accordingly, if the position of the insertion frame 20 on the second insertion portion 205 side is slightly shifted in this state, the first insertion portion 203 remains inserted into the second insertion frame receiving portion 156. In the state, the insertion of the second insertion portion 205 into the second insertion frame receiving portion 156 can be released. In the state in which only the side portion on the first insertion portion 203 side of the insertion frame 20 is held by the rack body 10, the insertion frame 20 can be easily made with the first insertion portion 203 as the rotation center. The insertion frame 20 is in a state like an opening / closing door of the folding rack 1. That is, with this state, it is possible to easily carry in / out the luggage to / from the folding rack 1 from the surface of the insertion frame 20.

A usage form of the folding rack 1 having such a configuration will be described.
When the foldable rack 1 is used, the two fixed frames 150 of the rack body 10 are raised, and the pallet unit 110 is erected on opposite edges.

  Next, the insertion frames 20 are respectively mounted between the opposing sides of the two fixed frames 150 arranged to face each other. The insertion frame 20 is mounted by dropping the insertion frame 20 from the upper part between the fixed frames 150, and the first insertion part 203 and the second insertion part 205 of the insertion frame 20 are respectively fixed to the fixed frame 150. The first insertion frame receiving portion 155 and the second insertion frame receiving portion 156 are inserted into the second insertion frame receiving portion 156. Thereby, the fixed frame 150 which opposes will be in the state connected with the insertion frame 20 as shown to FIG. 4 (A), and the sturdy folding rack 1 without backlash is formed.

  When an article is carried into and out of the foldable rack 1 assembled in this way, the insertion frame 20 is slightly lifted, and the second insertion portion 205 of the insertion frame 20 is shown in FIG. The insertion frame 20 is lifted slightly to the extent that the insertion into the second insertion frame receiving portion 156 is released, and the position of the end portion on the second insertion portion 205 side is slightly shifted. After slightly shifting the position of the end portion on the second insertion portion 205 side to release the insertion of the second insertion portion 205 into the second insertion frame receiving portion 156, the insertion frame 20 is You can drop it again. That is, the state where the insertion frame 20 is lifted may be released. As a result, the insertion frame 20 is maintained in a cantilevered state by the rack body 10 because the first insertion portion 203 is inserted into the first insertion frame receiving portion 155, and the first insertion portion It is in a state of being rotatable around the position of 203 as the rotation center. That is, the insertion frame 20 is in a state corresponding to a door for the accommodation space of the folding rack 1. Therefore, in this state, articles can be easily carried into and out of the foldable rack 1.

  In addition, after lifting the insertion frame 20 and releasing the insertion of the second insertion part 205 into the second insertion frame receiving part 156, the direction in which the insertion frame 20 is shifted is the inside of the folding rack 1. Either the side or the outside can be used, or both are possible. In other words, depending on the shifting method, the insertion frame 20 can be rotated to a so-called inwardly open door state, or can be rotated to a so-called outwardly open state. In storing and carrying out the article, it is preferable to shift the insertion frame 20 to the outside and rotate it to a so-called outwardly opened state.

  When the storage of the article is completed and the article is conveyed by the foldable rack 1, the insertion frame 20 is lifted again, and the second insertion part 205 is inserted into the second insertion frame receiving part 156. As a result, the two fixed frames 150 and the two insertion frames 20 are firmly connected again without rattling, and the contents can be safely transported.

  When the folding of the foldable rack 1 is completed after the transport of the contents, the insertion frame 20 is completely lifted and separated from the rack body 10. By separating the two insertion frames 20, the fixed frame 150 of the rack body 10 can be tilted inward. Therefore, for example, by placing the separated insertion frame 20 on the pallet unit 110 and tilting the two fixed frames 150 sequentially on the insertion frame 20, the folding rack 1 is in a folded state. Become.

The folding rack 1 folded in this way can be stacked as shown in FIG. 5 by sequentially stacking the stacking metal fittings 130 so as to be fitted to the upper parts of the corner metal fittings 120.
As a result, the folding rack 1 can be forwarded easily and efficiently.

As described above, in the foldable rack 1 of the present embodiment, the two fixed frames 150 arranged to face each other are connected by the insertion frame 20 having the two connecting columns 201. Therefore, when the foldable rack 1 is assembled, rattling of the fixed frame 150 can be almost completely eliminated, and the foldable rack 1 having high rigidity and strength can be realized.
As a result, it is possible to provide the foldable rack 1 capable of transporting the stored items more safely.

  Further, in the foldable rack 1, by changing the lengths of the insertion portions 203 and 205 on both sides of the insertion frame 20, the insertion frame 20 can be opened and closed like a door while maintaining the cantilever state. . Accordingly, it is possible to easily carry in / out the article with respect to the inside of the foldable rack 1 and to improve the efficiency of the article carrying work and the like.

  Further, when folding, the volume can be greatly reduced by folding the fixed frame 150, and stacking can be performed safely and easily. Accordingly, the folding rack 1 can be easily and efficiently forwarded.
