Description

[Technical Field]

[0001] The present invention relates to panels used in boxes (also called baskets) for transporting and storing materials, and in particular to panels that can be easily replaced with respect to a frame body. [Background technology]

[0002] At construction sites, factories, delivery centers, etc., 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 carts (also called basket carts) by attaching carts to them (Patent Document 1).

[0003] Such boxes, container trucks, etc. generally use wire mesh as panel plates to reduce weight. [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 having 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 created the problem that users must possess multiple container trucks to accommodate the various materials they handle, and also requires additional storage space.

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

[0009] In order to solve the above problem, the invention described in claim 1 provides a frame body having a groove formed therein extending in the longitudinal direction, a panel board that is fitted into the groove of the frame body, and a press-fit member that is press-fitted between the inner wall of the groove and the panel board fitted into the groove, and the panel board can be detached from the frame body by inserting and removing the press-fit member in the surface direction of the panel board, When the panel plate is fitted into the recessed groove of the frame body, a part of a member constituting the panel plate protrudes from another part of the member constituting the panel plate toward the inner wall of the recessed groove, A protrusion is formed on the inner wall of the recessed groove, and the press-fitting member passes over the protrusion to form the panel plate. The aforementioned A part of the groove constitutes the inner wall of the groove and the panel plate. Ru Department Material The aforementioned The inner wall of the recessed groove formed between the panel plate and another part of the recessed groove is Ru Department Material The aforementioned It is characterized by being pressed into a gap between another part.

[0010] The invention described in claim 2 is characterized in that, in the panel described in claim 1, corner members are provided at the corner portions formed by two adjacent frame bodies, which fit into each of the grooves and are fixed to each frame body.

[0011] The invention described in claim 3 is a box using the panel described in claim 1 or claim 2, characterized in that at least four sides are surrounded by the panel. [Effects of the Invention]

[0012] According to the invention described in claim 1, the panel plate can be easily attached to and detached from the frame body simply by inserting and removing the press-in member into the gap between the recessed groove of the frame body and the panel plate fitted therein.

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

[0014] This eliminates the need to prepare multiple types of boxes or container carts to suit the characteristics of each material, and by preparing panel plates with different wire mesh pitches, a box suitable for the intended use 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 and stored by removing the press-fitting members and detaching the panel board from the frame body.

[0016] According to the invention described in claim 2, 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.Therefore, even if the wire mesh is a relatively weak panel plate, it can be made into a strong panel when assembled.

[0017] According to the invention described in claim 3, the box is constructed using panels that allow the panel boards to be easily removed from the frame body, so that the box can be easily assembled according to the intended use, and the panel boards can be disassembled from the frame body and stored, thereby saving space in the storage area.

[0019] The present invention will be described below based on the illustrated embodiments.

[0020] 1 to 8 illustrate 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. FIG.

[0021] The container cart 3 is configured by mounting a box 2 having a total length of approximately 3000 mm, a width of approximately 1000 mm, and a height of approximately 1500 mm on the top 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 made up 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 3000 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 length from front to back and is composed of three panel plates 10, with each panel plate 10 arranged in one of three spaces surrounded by front and 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 made of, for example, steel, and is formed by joining vertical reinforcing bars 10a and horizontal reinforcing bars 10b, each with a wire diameter of 3.8 mm, to form a wire mesh with a mesh pitch of 80 mm, and the panel board used in the above panel 1 is formed to a size of approximately 970 mm x 600 mm. Note that horizontal reinforcing bars 10b are joined to the vertical edges of the panel board 10 so as to bridge the ends of each vertical reinforcing bar 10a, and vertical reinforcing bars 10a are joined to the horizontal edges so as to bridge the ends of each horizontal reinforcing bar 10b.

[0027] The frame body 12 is made of aluminum, for example, and is formed as a single unit, and is composed of a 20 x 30 mm rectangular pillar 12a and a pair of support pieces 12b that protrude from one side of the pillar 12a and extend parallel to each other, with a deep groove 13 formed between the pair of support pieces 12b, which are approximately 3 mm thick and protrude by approximately 20 mm.In the intermediate frame body 12B, the pair of support pieces 12b protrude from both side faces of the pillar 12a, and the 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 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 reinforcement 10a and the horizontal reinforcement 10b, and is approximately 7.0 mm because the vertical reinforcement 10a and the horizontal reinforcement 10b, each having a wire diameter of 3.8 mm, are joined by welding. The depth of the groove 13 to its innermost portion is approximately 20 mm.

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

[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 a frame frame 11.

[0032] The corner member 14 is made of aluminum, for example, and is formed in the shape of a substantially right-angled isosceles triangle 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 surface of the upper frame body 12C abutting against the surface on which the groove 13 is formed at the upper end of the front frame body 12A, and the support piece 12b and the corner member 14 are fixed by a bolt or the like.

[0034] These corner members 14 function as reinforcing members when the four frame bodies 12 are assembled into a frame shape. Moreover, since the recessed grooves 13 provided for fixing the panel boards 10 are utilized, simply providing the corner members 14 that fit into the recessed grooves 13 does not require any other special structure or members for reinforcement, and reinforcement can be achieved with an extremely simple structure.

[0035] The panel board 10 has vertical reinforcement 10a or horizontal reinforcement 10b positioned on either side edge, 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 board 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 board 10 (vertical reinforcement 10a or horizontal reinforcement 10b).

[0037] The press-in member 15 is, for example, a plate made of aluminum, and has 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 on the other side edge.

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

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

[0040] Furthermore, when the press-fit member 15 is press-fitted between the recessed groove 13 and the panel board 10, the protrusion 12c of the support piece 12b is provided, so that the press-fit member 15 overcomes this and is thereby prevented from coming off. If the press-fit member 15 is also provided with a protrusion, the press-fit member 15 can be further prevented from coming off.

[0041] The length of such press-fit members 15 is the same as the length of the side edges of the panel board 10, and is, for example, approximately 970 mm for the upper and lower frame bodies 12C, and approximately 600 mm for the intermediate frame body 12B and the front and rear frame bodies 12A. The length of the press-fit members 15 does not need to be the same as the length of the frame body 12; they may be shorter. However, a stable press-fit state can be maintained by making the length of the press-fit members 15 longer than the wire mesh pitch of 80 mm and fixing at least two vertical reinforcements 10a or horizontal reinforcements 10b. When using press-fit members 15 shorter than the frame body 12, it is preferable to provide multiple press-fit members 15 for one frame body 12.

[0042] 2 constitutes the right wall of the box 2, with the vertical reinforcement 10a positioned on the outside of the box 2 and the horizontal reinforcement 10b positioned on the inside of 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 on the outside of 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 the press-fit member 15 is inserted into this gap.

[0043] That is, the press-fitting 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-fitting member 15 and is pressed against the outer support piece 12b. As a result, the vertical reinforcement 10a on the upper edge is clamped between the press-fitting 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-fit 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 reinforcement 10b at the front or rear edge of the panel board 10 press-fitted into these grooves 13 is fixed to the front and rear frame bodies 12A or the intermediate frame body 12B.

[0046] That is, the press-fit members 15 are inserted into the recessed grooves 13 from the outside of the box 2, and the horizontal reinforcement bars 10b are pressed toward the inside of the box 2 by the press-fit members 15 and pressed against the inner support pieces 12b, and the panel board 10 is fixed to the front and rear frame bodies 12A by being sandwiched between the press-fit members 15 and the support pieces 12b. Also, in the intermediate frame body 12B, the press-fit members 15 are pressed in the same way as in the front and rear frame bodies 12A, and the horizontal reinforcement bars 10b are 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 the parts and make handling easier.

[0048] The panel 1 is assembled by attaching the frame body 12 to the panel board 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 and fitted into each of the grooves 13. After fitting the panel plate 10 into the three frame bodies 12, the remaining frame body 12 is assembled by fitting the corner members 14 to the other frame bodies 12 and fitting the side edges of the panel plate 10 into the grooves 13 of that frame body 12, thereby assembling the frame 11, and then press-fitting members 15 into each of the grooves 13 as described above to complete the panel 1.

[0050] In this way, the panel board 10 is attached to the frame 11 by fixing the four side edges of the panel board 10 to the frame body 12. Then, three panel boards 10 are fixed to the frame body 12 in the same way to form one panel 1.

[0051] As described above, the box 2 has two panels 1, one on the top and one on the bottom, on each of the left and right sides, and one panel 1 on each of 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 made up 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 recessed 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, but even such a thing can be addressed by changing to a press-fit member with a different thickness.

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

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

[0057] While the embodiments of the present invention have been described above, the specific configuration is not limited to the above embodiments, and design changes within the scope of the present invention are also included. For example, while the above embodiments use aluminum press-fit members, the present invention may also use hard plastic or rubber-like materials. Furthermore, while the press-fit members have been described as having a uniform thickness, they may also be wedge-shaped, becoming thinner in the press-fit direction. The wedge shape allows the panel to be securely fixed to the frame body even if there is some degree of dimensional accuracy (such as the thickness of the panel, the spacing between the grooves, and the thickness accuracy of the press-fit member).
