Description

[Technical field]

[0001] The present invention relates to a panel used in a box (also called a basket) for transporting and storing materials, and in particular to a panel that allows the panel to be easily replaced with respect to a frame body. [Background technology]

[0002] At construction sites, factories, or distribution centers, boxes (also called box pallets) are used to transport and store materials such as finished products or raw materials. Boxes may also be used as container dollies (also called cage dollies) by attaching dollies (Patent Document 1).

[0003] In order to reduce weight, such boxes, container carts, etc. generally use wire mesh as the panel plates. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4749841 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, since this type of container cart is expected to transport a variety of materials, it is common for multiple types of container carts with panel plates with different wire mesh pitches to be prepared in advance, and for users to select a container cart that suits the characteristics of the materials they are handling.

[0006] Furthermore, when the transported material is powder or granular material, wire mesh panels cannot be used.

[0007] This has resulted in the user having to possess multiple container carts to accommodate the various materials being handled, and also in the need for storage space for these carts.

[0008] Therefore, an object of the present invention is to provide a panel and a box using the same that allow the panel boards (wire mesh, pitch, iron plate, etc.) fixed to the frame body to be easily replaced depending on the purpose of use. [Means for solving the problem]

[0009] In order to solve the above problems, a panel according to the present invention comprises a frame body in which a groove extending in the longitudinal direction is formed, a panel plate that is fitted into the groove of the frame body, and a press-in member that is pressed between the inner wall of the groove and the panel plate fitted into the groove, and the panel plate can be freely attached and detached from the frame body by inserting and removing the press-in member in the surface direction of the panel plate, and the panel plate may be a wire mesh formed by joining vertical reinforcement and horizontal reinforcement, the joint between the vertical reinforcement and the horizontal reinforcement being located at the back of the groove, and the press-in member being pressed between the inner wall of the groove and the vertical reinforcement or the horizontal reinforcement.

[0010] The panel according to the present invention may be configured so that a corner member is provided at a corner portion defined by two adjacent frame bodies, the corner member being fitted into each of the recessed grooves and fixed to each of the frame bodies.

[0011] The box according to the present invention may be a box using the above-mentioned panels, at least four sides of which are surrounded by the panels. Effect of the Invention

[0012] According to the present invention, the panel plate can be easily attached to and detached from the frame body by simply inserting and removing the press-in member into and from the gap between the recessed groove of the frame body and the panel plate fitted therein.

[0013] Furthermore, by varying the thickness of the press-in member, it is possible to select panel plates of different thicknesses (wire mesh, pitch, iron plate, etc.) to be fixed to the frame body, thereby making it possible to easily assemble a box using panel plates suited to the intended use.

[0014] This eliminates the need to prepare multiple types of boxes or container carts to suit the characteristics of each material. By simply preparing panel plates with different wire mesh pitches, a box suitable for the intended purpose can be assembled by selecting the desired panel plate and attaching it to the frame body.

[0015] Furthermore, when storing these boxes, they can be disassembled for storage by removing the press-fitting members and detaching the panel board from the frame body.

[0016] According to the present invention, when corner members are provided at the corner portions of two adjacent frame bodies, which fit into their respective grooves and are fixed to each frame body, even if a wire mesh, which is a relatively weak panel plate, is used as the panel plate, it can be made into a strong panel when assembled.

[0017] According to the present invention, when a box is constructed using panels that allow the panel boards to be easily removed from the frame body, the box can be easily assembled according to the intended use, and the panel boards can be disassembled from the frame body for storage, thereby saving space required for storage.

[0019] Hereinafter, the present invention will be described based on the illustrated embodiment.

[0020] 1 to 8 show an embodiment of the present invention, in which a panel 1 according to the present invention and a box 2 using the panel 1 are applied to a container cart 3. In FIG.

[0021] The container cart 3 is configured by mounting a box 2 having a total length of, for example, about 3000 mm, a width dimension of about 1000 mm, and a height of about 1500 mm on the upper surface of a base cart 32 with casters 31 (see FIG. 1).

[0022] The box 2 is constructed by assembling multiple panels 1 into a box shape with the top open, and the left and right sides (beam surfaces) are composed of two panels 1, one above the other, with the upper panel 1 rotatably attached to the lower panel 1, making it foldable.

[0023] The size of the panels 1 varies depending on which surface is used. For example, the panel 1 on the upper side of the girder surface is approximately 3,000 mm long in the front-to-back direction and approximately 600 mm high (see Figure 1).

[0024] The panel 1 is constructed by a rectangular panel plate 10 made of wire mesh, the four side edges of which are surrounded and fixed by a frame body 12.

[0025] The panel 1 in this embodiment is long in front-to-rear length and is composed of three panel plates 10, with each panel plate 10 being arranged in one of three spaces surrounded by front-to-rear frame bodies 12A at both front and rear ends, two intermediate frame bodies 12B arranged in the middle in the front-to-rear direction, and upper and lower frame bodies 12C at both top and bottom ends.

[0026] The panel board 10 is formed, for example, of a wire mesh with a mesh pitch of 80 mm by joining vertical bars 10a and horizontal bars 10b made of steel and having a wire diameter of 3.8 mm, and the size of the panel board used in the above panel 1 is approximately 970 mm x 600 mm. Horizontal bars 10b are joined to the vertical edges of the panel board 10 so as to bridge the ends of the vertical bars 10a, and vertical bars 10a are joined to the horizontal edges so as to bridge the ends of the horizontal bars 10b.

[0027] The frame body 12 is integrally formed, for example, from aluminum, and is composed of a 20 x 30 mm rectangular pillar 12a and a pair of support pieces 12b that are protruding from one side of the pillar 12a and extend parallel to each other while facing each other, with a deep recessed groove 13 formed between the pair of support pieces 12b, which are formed to a thickness of about 3 mm and a protruding amount of about 20 mm. Note that in the intermediate frame body 12B, the pair of support pieces 12b protrude from both sides of the pillar 12a, and a recessed groove 13 is formed between the pair of support pieces 12b in the same manner as described above.

[0028] The width of the groove 13 is, for example, 7.0 mm, which is formed to be approximately the same as or slightly smaller than the thickness of the panel plate 10. Here, the thickness of the panel plate 10 refers to the thickness of the joint between the vertical bars 10a and the horizontal bars 10b, and is approximately 7.0 mm because the vertical bars 10a and the horizontal bars 10b, each having a wire diameter of 3.8 mm, are joined by welding. The depth of the groove 13 to the innermost part is formed to be approximately 20 mm.

[0029] A flat convex portion 12c having a small protrusion amount, for example 0.5 mm, is formed on each of the surfaces of the pair of support pieces 12b facing each other.

[0030] The support pieces 12b of each frame body 12 extend downward in the upper frame body 12C, upward in the lower frame body 12C, rearward in the front frame body 12A, forward in the rear frame body 12A, and forward and rearward in the intermediate frame body 12B, and therefore each groove 13 opens toward the inside of the frame 11.

[0031] At the corners formed by two adjacent frame bodies 12, corner members 14 are provided which fit into the respective grooves 13 and are fixed to each frame body 12, thereby assembling each frame body 12 into a frame shape to form the frame frame 11.

[0032] The corner member 14 is made of aluminum, for example, and is formed in a substantially right-angled isosceles triangle shape with a thickness of about 7.0 mm, and is fitted into the recessed groove 13 (see Figs. 3 and 4).

[0033] The corner member 14 is fitted into the groove 13 of both frame bodies 12, for example, with the front end face of the upper frame body 12C abutting against the surface on the upper end of the front frame body 12A on which the groove 13 is formed, and the support piece 12b and the corner member 14 are fixed together by a bolt or the like.

[0034] Such corner members 14 function as reinforcing members when the four frame bodies 12 are assembled into a frame shape. Moreover, since the grooves 13 provided for fixing the panel boards 10 are utilized, no other special structure or members are required for reinforcement by simply providing the corner members 14 that fit into the grooves 13, and reinforcement can be achieved with an extremely simple structure.

[0035] Vertical reinforcement 10a or horizontal reinforcement 10b is positioned on either side edge of the panel board 10, and when fitted into the groove 13, the joint between the vertical reinforcement 10a and the horizontal reinforcement 10b is positioned at the back of the groove 13, and the panel board 10 is fitted somewhat tightly at the back of the groove 13.

[0036] The panel plate 10 fitted into the groove 13 of each frame body 12 is fixed to the frame body 12 by pressing a press-in member 15 between the groove 13 and the panel plate 10 (vertical reinforcement 10a or horizontal reinforcement 10b).

[0037] The press-in member 15 is, for example, in the form of an aluminum plate, and is formed with an L-shaped cross section with a protruding portion 15a that protrudes in the thickness direction from one longitudinal side edge, and a chamfered portion 15b is provided on the other side edge.

[0038] By providing a protrusion 15a on one side edge of the press-in member 15, the width of the side (plate thickness) becomes larger, making it easier to strike with a hammer when pressing in, and also providing a hook against which the tip of a screwdriver can be pressed when removing the press-in member 15. Also, by providing a chamfered portion 15b on the other side edge, it becomes easier to fit the press-in member 15 between the groove 13 and the panel plate 10.

[0039] Such a press-in member 15 is formed with a plate thickness of approximately 3.0 mm and a plate width of 15 mm, and when the press-in member 15 is pressed into the groove 13, there is no interference even if there are vertical bars 10a or horizontal bars 10b between its tip and the back of the groove.

[0040] Furthermore, when the press-fit member 15 is press-fitted between the recessed groove 13 and the panel plate 10, the press-fit member 15 overcomes the protrusion 12c of the support piece 12b, which prevents the press-fit member 15 from coming out. If a protrusion is also provided on the press-fit member 15, the press-fit member 15 can be further prevented from coming out.

[0041] The length of such a press-in member 15 is the same as the length of the side edge of the panel plate 10, and is formed, for example, to about 970 mm for the upper and lower frame bodies 12C, and about 600 mm for the intermediate frame body 12B and the front and rear frame bodies 12A. The length of the press-in member 15 does not need to be the same as the length of the frame body 12, and may be shorter. However, the length of the press-in member 15 is set to be longer than the wire mesh pitch of 80 mm, and at least two vertical bars 10a or horizontal bars 10b are fixed to maintain a stable press-in state. When using a press-in member 15 having a length shorter than that of the frame body 12, it is preferable to provide multiple press-in members 15 for one frame body 12.

[0042] 2 constitutes the right side wall of a box 2, with vertical reinforcement 10a positioned outside the box 2 and horizontal reinforcement 10b positioned inside the box 2. When the panel board 10 is fitted into the groove 13 of this upper frame body 12C, the vertical reinforcement 10a is positioned outside the box 2 at the back of the groove 13, creating a gap between the vertical reinforcement 10a and the inner support piece 12b, and a press-in member 15 is inserted into this gap.

[0043] That is, the press-in member 15 is inserted into the recessed groove 13 from the inside of the box 2, and the vertical reinforcement 10a is pressed to the outside of the box 2 by the press-in member 15 and pressed against the outer support piece 12b. As a result, the vertical reinforcement 10a on the upper edge is clamped between the press-in member 15 and the support piece 12b, and the upper edge of the panel board 10 is fixed to the upper frame body 12C.

[0044] Similarly, in the lower frame body 12C, a press-in member 15 is inserted between the vertical reinforcement 10a on the lower edge and the inner support piece 12b, thereby fixing the lower edge of the panel board 10 to the lower frame body 12C.

[0045] In contrast, in the front and rear frame bodies 12A and the intermediate frame body 12B, the horizontal bars 10b at the front or rear edge of the panel plate 10 pressed into these grooves 13 are fixed to the front and rear frame bodies 12A or the intermediate frame body 12B.

[0046] That is, the press-in member 15 is inserted into the recessed groove 13 from the outside of the box 2, and the horizontal reinforcement 10b is pressed toward the inside of the box 2 by the press-in member 15 and pressed against the inner support piece 12b, and the panel board 10 is fixed to the front and rear frame bodies 12A by being sandwiched between the press-in member 15 and the support piece 12b. Also, in the intermediate frame body 12B, the press-in member 15 is pressed in like the front and rear frame bodies 12A, so that the horizontal reinforcement 10b is pressed toward the inside of the box 2.

[0047] In this way, the same press-in member 15 can be used to fix the panel board 10 to the upper and lower frame bodies 12C, to the front and rear frame bodies 12A, and to the intermediate frame body 12B, making it possible to standardize parts and facilitate handling.

[0048] The panel 1 is assembled by attaching the frame body 12 to the panel plate 10 as follows.

[0049] For example, three frame bodies 12 are assembled into a U-shape via corner members 14, and before assembling the last frame body 12, a panel plate 10 is slid from the open side of the U-shape to fit into each of the grooves 13. Then, after fitting the panel plate 10 to the three frame bodies 12, the remaining frame body 12 is fitted to the other frame bodies 12 via the corner members 14 so that the side edges of the panel plate 10 fit into the grooves 13 of that frame body 12, thereby assembling the frame 11, and then the press-in members 15 are press-fitted into each of the grooves 13 as described above, thereby completing the panel 1.

[0050] In this manner, the panel plate 10 is attached to the frame 11 by fixing the four side edges of the panel plate 10 to the frame body 12. Similarly, three panel plates 10 are fixed to the frame body 12 to form one panel 1.

[0051] Thus, as described above, the box 2 is provided with two panels 1, one above and one below, on each of the two left and right sides, and one panel 1 each on the front and back sides, which are assembled using hinges, connecting members, etc.

[0052] The box 2 is constructed by assembling multiple panels 1 into a box shape with the top open, and the left and right sides (beam surfaces) are composed of two panels 1, one above the other, with the upper panel 1 of the lower panel 1 rotatably attached and foldable.

[0053] As described above, in the panel 1 of the present invention, the panel plate 10 can be fixed simply by fitting the press-in member 15 together with the panel plate 10 into the groove 13 of the frame body 12. Therefore, by preparing press-in members 15 of different thicknesses, boxes 2 can be created with panel plates 10 of various thicknesses.

[0054] In other words, wire mesh with different pitches has different wire diameters for the vertical and horizontal bars that make it up, which results in different thicknesses for the panel board; however, this can be accommodated by changing to press-in members of different thicknesses.

[0055] Therefore, this invention is not limited to the wire mesh shown in the above embodiment, but can be applied to panel plates of various different thicknesses such as steel plates and corrugated plastic, and as long as you prepare only the panel plate that suits the intended use, there is no need to prepare boxes or container carts for each intended use.

[0056] Moreover, since the panel 1 can be easily disassembled into the frame body 12 and the panel plate 10, the storage space for the boxes 2 and the container carts 3 can be saved.

[0057] Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and the present invention includes design changes within the scope of the present invention. For example, in the above embodiment, the press-in member is made of aluminum, but the present invention may use such hard plastic or rubber-like material. In addition, the press-in member has been described as having a uniform thickness, but it may be a so-called wedge-shaped member that becomes thinner in the press-in direction. By making it wedge-shaped, the panel plate can be reliably fixed to the frame body even if there is some dimensional accuracy (such as the thickness of the panel plate, the interval between the grooves, and the thickness accuracy of the press-in member).
