Description

The present invention relates to panels used in boxes (also called cages) for transporting and storing materials, and in particular to panels that allow panel plates to be easily replaced relative to the frame body.

At construction sites, factories, distribution centers, and the like, 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).

In order to reduce weight, such boxes, container carts, etc. typically use wire mesh as the paneling.

Patent No. 4749841

Since container carts of this type are expected to transport a variety of materials, it is common for users to prepare multiple types of container carts with panel plates with different wire mesh pitches in advance, and select a container cart that matches the characteristics of the materials they are handling.

In addition, if the material being transported is powder or granular material, wire mesh panels cannot be used.

This meant that users had to own multiple container carts to accommodate the various materials they handled, and they also had to find storage space for them.

Therefore, the objective of this invention is to provide a panel and a box using the same in which the panel plates (wire mesh, pitch, steel plate, etc.) fixed to the frame body can be easily replaced depending on the purpose of use.

In order to solve the above problem, the invention described in claim 1 comprises a frame body having a groove extending in the longitudinal direction, a panel plate fitted into the groove of the frame body, and a press-in member pressed between the inner wall of the groove and the panel plate fitted into the groove, wherein the press-in member can be inserted and removed in the surface direction of the panel plate to make the panel plate detachable from the frame body , and wherein when the panel plate is fitted into the 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 groove, a convex portion is formed on the inner wall of the groove, and the press-in member overcomes the convex portion and is pressed into a gap between the inner wall of the groove and the other part of the member constituting the panel plate, which is formed by positioning the part of the member constituting the panel plate between the inner wall of the groove and the other part of the member constituting the panel plate.

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

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.

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.

By changing the thickness of the press-in members, it is possible to select panels of different thicknesses (wire mesh, pitch, steel plate, etc.) to be fixed to the frame body, making it easy to assemble a box using panels suited to the intended use.

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

Furthermore, when storing these boxes, they can be disassembled and stored by removing the press-in members and detaching the panel from the frame body.

According to the invention described in claim 2, corner members are provided at the corners of two adjacent frame bodies that fit into the respective grooves and are fixed to each frame body, so that even if the panel plate is made of relatively weak wire mesh, it can be made into a strong panel when assembled.

According to the invention described in claim 3, the box is constructed using panels that can be easily removed from the frame body, so the box can be easily assembled according to the intended use, and the panel boards can be disassembled from the frame body for storage, which also saves storage space.

The present invention will be described below based on the illustrated embodiment.

Figures 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.

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 Figure 1).

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.

The size of the panels 1 varies depending on which panel is used for each surface, but for example, the panel 1 on the upper side of the girder surface is formed to have a length of approximately 3000 mm in the front-to-rear direction and a height of approximately 600 mm (see Figure 1).

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

The panel 1 in this embodiment is long in the front-to-rear direction and is composed of three panel plates 10, with each panel plate 10 being arranged in 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.

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

The frame body 12 is made of aluminum, for example, and is formed as a single unit. It 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 approximately 20 mm. In the intermediate frame body 12B, the pair of support pieces 12b protrude from both sides of the pillar 12a, and a groove 13 is formed between the pair of support pieces 12b in the same manner as described above.

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 bars 10a and the horizontal bars 10b, and is approximately 7.0 mm because the vertical bars 10a and the horizontal bars 10b, which have a wire diameter of 3.8 mm, are joined by welding. In addition, the depth of the groove 13 to the back is approximately 20 mm.

On the opposing surfaces of the pair of support pieces 12b, flat convex portions 12c with a small protrusion amount, for example 0.5 mm, are formed.

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, so that each groove 13 opens toward the inside of the frame 11.

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, whereby each frame body 12 is assembled into a frame shape to form the frame frame 11.

The corner member 14 is made of aluminum, for example, and is formed in the shape of an approximately right-angled isosceles triangle with a thickness of approximately 7.0 mm, and is fitted into the groove 13 (see Figures 3 and 4).

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 butted against the surface on the top end of the front frame body 12A where the groove 13 is formed, and the support piece 12b and the corner member 14 are fixed together with a bolt or the like.

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

The panel board 10 has vertical reinforcement 10a or horizontal reinforcement 10b on either side edge, and when fitted into the groove 13, the joint between the vertical reinforcement 10a and the horizontal reinforcement 10b is located at the back of the groove 13, and the panel board 10 fits somewhat tightly at the back of the groove 13.

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).

The press-in member 15 is, for example, an aluminum plate, with a protrusion 15a that protrudes in the thickness direction from one longitudinal edge, forming an L-shaped cross section, and a chamfered portion 15b on the other longitudinal edge.

Providing a protrusion 15a on one side edge of the press-in member 15 increases the width of the side (plate thickness), 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, providing a chamfered portion 15b on the other side edge makes it easier to fit the press-in member 15 between the recessed groove 13 and the panel plate 10.

The press-in member 15 has a thickness of approximately 3.0 mm and a 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 the tip and the back of the groove.

In addition, when the press-in member 15 is pressed into the gap between the groove 13 and the panel plate 10, the press-in member 15 overcomes the protrusion 12c of the support piece 12b, which prevents the press-in member 15 from coming loose. If the press-in member 15 is also provided with a protrusion, the press-in member 15 can be further prevented from coming loose.

The length of such press-in members 15 is the same as the length of the side edge of the panel plate 10, and is formed to, for example, 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 it 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 with a length shorter than the frame body 12, it is preferable to provide multiple press-in members 15 for one frame body 12.

The panel 1 shown in Figure 2 constitutes the right side 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 the 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-in member 15 is inserted into this gap.

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.

Similarly, in the lower frame body 12C, the lower edge of the panel board 10 is fixed to the lower frame body 12C by inserting a press-in member 15 between the vertical reinforcement 10a at the lower edge and the inner support piece 12b.

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.

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 plate 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 the same way as in the front and rear frame bodies 12A, so that the horizontal reinforcement 10b is pressed toward the inside of the box 2.

In this way, the same press-in member 15 can be used to fasten the panel plate 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.

The frame body 12 is attached to the panel board 10 to assemble the panel 1 as follows.

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

In this way, 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. Then, three panel plates 10 are fixed to the frame body 12 in the same manner to form one panel 1.

As described above, the box 2 has 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.

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.

As described above, in the panel 1 of this 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.

In other words, wire mesh with different pitches has different diameters for the vertical and horizontal bars that make it up, which results in different thicknesses for the panel board, but this can be addressed by changing to press-in components of different thicknesses.

Therefore, this invention is not limited to the wire mesh shown in the above embodiment, but can be applied to panels of various 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.

In addition, the panel 1 can be easily disassembled into the frame body 12 and the panel plate 10, which allows for space saving for storing the boxes 2 and container carts 3.

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 that do not deviate from the gist of the present invention. For example, in the above embodiment, the press-in member is made of aluminum, but the present invention can also use hard plastic or rubber-like materials. In addition, the press-in member has been described as having a uniform thickness, but it can also 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 spacing between the grooves, and the thickness accuracy of the press-in member).
