Description

[Technical Field]

[0001] This invention relates to a folding table, and more particularly to a folding table made by folding a thin, foldable panel (plate-shaped member) such as cardboard or plastic sheet. [Background technology]

[0002] BACKGROUND ART Conventionally, there have been various folding tables made by folding a thin, foldable panel (plate-shaped member) such as cardboard.

[0003] For example, Patent Document 1 discloses a folding table in which a tabletop and legs are constructed by folding a single piece of cardboard. In this case, a separate "fixing component" is required to secure the folded legs. Also, a "folding line" is provided in the center of the tabletop for folding.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 9-140457 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when folding and unfolding a folding table frequently, such as when used outdoors, if additional components (such as fixing parts) are required, there is a risk of losing those components. If those components are lost, the folding table cannot be constructed. Furthermore, considering compactness when folded, it is unavoidable to fold the tabletop itself, which takes up the most space. However, if the tabletop itself has a "folding line" for folding, as in Patent Document 1, unevenness occurs at the fold line due to the restoring force of the fold, causing problems such as tilting of placed items. Furthermore, if the strength of the tabletop needs to be increased, the entire component, including the tabletop (corrugated cardboard in Patent Document 1), must be made stronger, which can lead to problems such as a significant increase in weight.

[0006] The present invention was made to solve these problems, and its objective is to provide a folding table that does not require any additional parts when folding, can be folded without creating a fold line on the top plate, and allows the strength of the top plate alone to be freely adjusted as needed. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention is a folding table made by folding a thin, foldable panel (plate-shaped member) such as cardboard or plastic sheet, and is characterized by a three-layer structure comprising a top panel divided into at least two parts, leg components arranged on the underside of the top panel and capable of forming legs by folding, a central panel equipped with a top support part for supporting the top panel, and a hinge panel attached and fixed to the underside of the top support part.

[0008] By adopting this structure, it is possible to provide a folding table that does not require additional components for folding, can be folded without a fold line on the tabletop, and allows the strength of the tabletop alone to be freely adjusted as needed. In other words, the tabletop is not folded but rather has a divided structure. It is supported by a central panel (the tabletop support portion) and the folding is supported by a hinge panel located on the underside of the central panel (the tabletop support portion). This eliminates the need to fold the tabletop itself. As a result, there are no fold lines on the tabletop, so no concave or convex portions are created, and items placed on it will not tilt. Furthermore, the three-layer structure, including the tabletop, allows the tabletop to be replaced with a stronger material (e.g., metal) as needed, leaving the rest of the tabletop intact. This allows the tabletop's strength to be increased without excessively increasing the overall weight.

[0009] The top support portion is divided into at least two parts in accordance with the division state of the top panel, and is folded in the divided state together with the top panel via the hinge panel.

[0010] By adopting this structure, it is possible to achieve a clean folding state. In other words, by dividing not only the top panel but also the top panel support part (of the center panel) by making cuts, the folding is supported only by the hinge panel part, and unnecessary stress is not generated in each component (top panel or top panel support part) when folding.

[0011] The tabletop panel can be folded in a state where the leg components are folded so as to overlap the tabletop support portion.

[0012] By adopting this structure, it is possible to achieve a compact size when folded.

[0013] The hinge panel is also characterized in that it is attached and fixed at a position where it does not overlap with the leg constituent elements when the leg constituent elements are folded so as to overlap with the tabletop support portion side.

[0014] By adopting this structure, it is possible to reduce the thickness when folded. [Effects of the Invention]

[0015] By applying this device, it is possible to provide a folding table that does not require any additional parts when folding, can be folded without providing a fold line on the top plate, and can freely change the strength of the top plate alone as needed. [Brief explanation of the drawings]

[0017] Below, we will explain a folding table 100, which is one example of an embodiment of the present invention, with reference to the accompanying drawings. Please note that in order to make the drawings easier to understand, the size and dimensions of various parts are exaggerated and may not necessarily match the actual product. Furthermore, each drawing should be viewed in accordance with the direction of the symbols, and the top, bottom, left, right, front, and back are expressed based on these directions.

[0018] <Configuration of folding table> A folding table 100 shown as an example of an embodiment of the present invention is composed of three layers of panels (a central panel 101, a top panel 102, and a hinge panel 103) as shown in Figure 1. Note that Figures 1 to 4 show the table upside down to show the folding structure.

[0019] The folding table 100 is a folding table made by folding a thin, bendable panel (plate-shaped member) made of, for example, plastic sheet, and has a three-layer structure comprising a top panel 102 divided into two, leg components 120 that are arranged on the underside of the top panel 102 (the upper side in Figure 1, as the top is upside down) and can be folded to form legs, a central panel 101 equipped with a top support part 110 for supporting the top panel 102, and a hinge panel 103 that is attached and fixed to the approximately central underside of the top support part 110 (the upper side in Figure 1, as the top is upside down) (see also Figures 2 and 9).

[0020] In addition, dotted lines in the central panel 101 in FIG. 1 indicate the positions of fold lines for folding. Specifically, these are fold line α, which is the boundary between the tabletop support portion 110 and the leg component 120, fold line β for folding the leg component partway, fold line γ for dividing the tabletop panel 102 into two and folding it, and fold line δ for raising the leg fixing panel 112. Note that fold line α and fold line γ each consist of two fold lines. Furthermore, no fold line is formed in the center of the tabletop support portion 110, and instead a notch 111 is provided for dividing the tabletop support portion 100 into two.

[0021] <Folding to create a folding table> Figure 2 shows the folding table 100 in a fully unfolded state. This state marks the start of folding. Next, as shown in Figure 3, the two leg fixing panels 112 are raised along the folding line δ, and then the leg components 120 are folded along the folding lines α and β. Then, the insertion holes 114 formed in the leg fixing panels 112 and the insertion holes 122 formed in the leg components 120 are inserted into each other and assembled, completing the folding table 100 ready for use (see Figures 4 and 5).

[0022] <Folding for storage of folding table> Next, folding for storage will be described. In this case, too, the unfolded state shown in Figure 2 is the starting point. Then, as shown in Figure 6, the leg components 120 are folded completely inward (toward the top support portion 110) along the folding line α. At this time, the hinge panel 103 is positioned so that it does not overlap with the folded leg components 120. Next, the top panel 102 is folded in half along the folding line γ (see Figures 7 and 10). When completely folded, the state shown in Figures 8 and 11 is reached, and folding for storage is complete.

[0023] As explained in the above configuration, the present invention is a folding table 100 made by folding a thin, foldable panel (plate-shaped member) such as cardboard or plastic sheet, and is characterized by a three-layer structure comprising a top panel 102 divided into at least two parts, leg components 120 arranged on the underside of the top panel 102 and capable of forming legs by folding, a central panel 101 equipped with a top support portion 110 for supporting the top panel 102, and a hinge panel 103 attached and fixed to the underside of the top support portion 110.

[0024] By adopting such a structure, no separate components are required for folding, the top plate (top plate panel 102) can be folded without providing a fold line, and the strength of the top plate alone can be freely adjusted as needed. That is, the top plate (top plate panel 102) is not folded but is made into a divided structure, and is supported by the central panel 101 (top plate support portion 110) while the folding is supported by the hinge panel 103 arranged on the underside of the central panel 101 (top plate support portion 110). Therefore, there is no need to fold the top plate (top plate panel 102) itself. As a result, there is no need to provide a fold line, and therefore no concave or convex parts are created in the top plate (top plate panel 102), and objects placed on it will not tilt. Furthermore, by using a three-layer structure including the top plate (top plate panel 102), if necessary, the top plate (top plate panel 102) can be changed to a stronger material (for example, a metal material) and the other parts can remain the same in structure, so that the strength of the top plate (top plate panel 102) can be increased without excessively increasing the overall weight.

[0025] The top support portion 110 is divided into at least two parts in accordance with the divided state of the top panel 102, and is characterized in that it is folded in the divided state together with the top panel 102 via the hinge panel 103.

[0026] By adopting this structure, it is possible to achieve a clean folding state as shown in Figures 9 and 10. That is, by dividing not only the top panel 102 but also the top support portion 110 (of the central panel 101) with slits 111, the folding is supported only at the hinge panel 103 portion, and unnecessary stress is not generated in the members (top panel 102 and top support portion 110) when folding.

[0027] In addition, the tabletop panel 102 can be folded in a state where the leg components 120 are folded so as to overlap the tabletop support portion 110 side.

[0028] By adopting this structure, it is possible to achieve a compact size when folded.

[0029] The hinge panel 103 is also characterized in that it is attached and fixed in a position where it does not overlap with the leg component 120 when the leg component 120 is folded so as to overlap the top board support portion 110 side.

[0030] By adopting such a structure, it is possible to reduce the thickness when folded (see FIG. 11). That is, since the folded leg components 120 and the hinge panel 103 are located in the same layer without overlapping, it is possible to reduce the thickness when folded. [Explanation of symbols]
