Description

[Technical field]

[0001] The present invention relates to a connecting member that connects insertion holes formed in open ends of plate-like members by adjacently connecting them. [Background technology]

[0002] Conventionally, for example, semiconductor manufacturing equipment often has a drive unit arranged inside a box, and panel-shaped materials are often used as the wall surfaces of the box. Panel-shaped materials are also often used in liquid crystal panel manufacturing equipment, etc. Furthermore, plate-shaped materials are used in various manufacturing sites, such as the inside of these devices often containing plate-shaped block materials having a certain thickness.

[0003] At an assembly site where such manufacturing equipment is assembled, it is common to assemble multiple pieces of equipment at one location, not just one. For this reason, a large number of plate-shaped materials are brought to the assembly site for assembly work, but because the floor space at the assembly site is limited, multiple plate-shaped materials are stored, for example, stacked flat on a pallet.

[0004] However, when multiple plate-like materials are stacked flat, the surface may be scratched, and after the device is assembled, these scratches may result in product complaints. For this reason, a known panel stand is used in which, for example, U-shaped angle members are arranged in parallel on a base member at intervals somewhat wider than the thickness of the plate-like materials, and the plate-like materials are held between adjacent U-shaped angle members. However, most of these panel stands are not disassembled and assembled, and installing multiple panel stands creates problems such as the inability to secure the space required for assembly work.

[0005] Therefore, the present inventor has developed a holder shelf assembly member that allows for low-cost manufacturing of the holder shelf and facilitates preparation work before assembling the holder shelf and cleanup after disassembly (see Patent Document 1). With this holder shelf assembly member, two comb-shaped members are stacked together to form a first assembly unit, and the two comb-shaped members are connected with a connecting member to form a second assembly unit, and the second assembly unit and the first assembly unit are combined to form the holder shelf.

[0006] The two comb-shaped members connected by the connecting member are made of plastic cardboard. The plastic cardboard has a hollow structure with a pair of flat plastic sheets connected by a plastic core, and an insertion hole is formed at the open end of the hollow structure of the comb-shaped member. The connecting member is formed of a connection member made of a flexible synthetic resin strip with a width that can be inserted into the insertion hole, and two tubular members made of synthetic resin cylinders with a diameter that is inscribed in the insertion hole.

[0007] The connecting member has one end inserted into one of the insertion holes at the tip of one of the two comb plate-shaped members, and the other end fitted into the insertion hole at the tip of the other comb plate-shaped member. Then, the two tubular members are fitted into the respective insertion holes, and the respective connecting members are pressed against the inside of the insertion holes to fix them in place. The two comb plate-shaped members connected in this way are rotatably connected to form a second assembly unit. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Patent No. 6154423 Summary of the Invention [Problem to be solved by the invention]

[0009] However, when using the above-mentioned connecting member to connect the two tubular members, it is necessary to fit the two tubular members into their respective insertion holes while maintaining a state in which both ends of the connecting member are inserted to appropriate positions into the insertion holes at the tips of the two comb-shaped members, which is a time-consuming and labor-intensive task.In addition, since the connecting member is composed of a total of three members, one connecting member and two tubular members, the number of parts is large, which is a factor in increasing costs.

[0010] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide a connecting member that connects plate-like members by adjacently positioning insertion holes formed in the open ends of the members, which has a reduced number of parts and facilitates the connecting operation. [Means for solving the problem]

[0011] The connecting member of the present invention is a connecting member that connects adjacent insertion holes formed in the open ends of a plate-like member, and has a first columnar portion that is inserted into and fits with one of the adjacent insertion holes, and a second columnar portion that is inserted into and fits with the other of the adjacent insertion holes after the first columnar portion, the second columnar portion being shorter than the first columnar portion, and a thin-walled portion that is thin-walled so as to be bendable, connecting the first columnar portion and the second columnar portion.

[0012] According to the connecting member of the present invention, a first columnar portion longer than the second columnar portion is first inserted into one of adjacent insertion holes, and then the second columnar portion shorter than the first columnar portion is inserted. Therefore, when the second columnar portion is inserted into the insertion hole, the second columnar portion is positioned by the first columnar portion previously inserted into the insertion hole, making it easy to insert the second columnar portion.

[0013] In the connecting member of the present invention, it is preferable that either or both of the tips of the first and second columnar sections are tapered, so that when the columnar sections are inserted into the insertion holes, the tapered shape of the tips acts as a guide, making it easy to insert the columnar sections into the insertion holes. Effect of the Invention

[0014] According to the connecting member of the present invention, adjacent insertion holes can be easily connected by first inserting the first columnar portion into one of the insertion holes and then inserting the second columnar portion, which has been positioned in this way, into the other insertion hole, thereby reducing the number of parts and thereby achieving cost reduction.

[Figure 6] 5 is an explanatory diagram showing a method of using the connecting member of FIG. 4. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] FIG. 1 is an oblique view of a holding shelf in an embodiment of the present invention, FIG. 2 is a diagram showing a first assembly unit of FIG. 1, where (A) is a plan view and (B) is a front view, and FIG. 3 is a diagram showing a second assembly unit of FIG. 1, where (A) is a plan view and (B) is a right side view.

[0017] 1, a holding shelf 1 according to an embodiment of the present invention is used, for example, at manufacturing sites for semiconductor devices, liquid crystal panel devices, etc., and is capable of holding plate-like materials, etc., required for assembling the devices, in a leaning state. The holding shelf 1 is formed by assembling using holding shelf assembly members including a first assembly unit 10 and a second assembly unit 20. Note that the holding shelf 1 can be used not only at manufacturing sites for semiconductor devices, etc., but also at various sites where plate-like materials are handled, such as construction sites, tatami mat replacement sites, woodworking workshops, etc.

[0018] 2, the first assembly unit 10 is configured by connecting two pairs of comb plate-shaped portions 13A, 13B formed into a comb plate shape by a rectangular plate-shaped base portion 11 and a plurality of comb-tooth plate portions 12 perpendicular to the base portion 11, that is, by including two pairs of comb plate-shaped portions 13A, 13B. The base portion 11 is formed of a rectangular plate-shaped plate member having a long side of length L1 according to the need such as the size of the plate-shaped material to be held.

[0019] The comb-tooth plate portion 12 is made of a rectangular plate member whose short sides have a first width W1. The comb-tooth plate portion 12 has its long sides 12A, 12B oriented in a direction perpendicular to the long sides 11A, 11B of the substrate portion 11. The comb-tooth plate portion 12 is arranged in parallel on the side of one long side 11A of the substrate portion 11 with a gap 15 of a second width W2 provided along the long side 11A of the substrate portion 11. The comb-tooth plate portion 12 is formed integrally with the substrate portion 11.

[0020] In this embodiment, each of the comb plate-shaped portions 13A and 13B forms an L shape with the substrate portion 11 and an end plate portion 121 located at the end of the multiple comb tooth plate portions 12 arranged in parallel. Furthermore, the end of the substrate portion 11 opposite the end plate portion 121 forms a protruding end 111. Specifically, the protruding end 111 protrudes from the comb tooth plate portion 122 opposite the end plate portion 121 of the multiple comb tooth plate portions 12 arranged in parallel along the long side 11A of the substrate portion 11 by a length of the second width W2 of the gaps 15 between the comb tooth plate portions 12.

[0021] In this embodiment, the protruding ends 111 of the two pairs of comb plate-shaped portions 13A, 13B face the same side, the tip faces of the respective comb tooth plate portions 12 are arranged opposite to each other, and one side 12A of the comb tooth plate portions 12 are connected. In addition, the surfaces of the long sides 11B of the substrate portions 11 of the two pairs of comb plate-shaped portions 13A, 13B, i.e., the surfaces of the long sides 11B that are one side of the ends opposite to the comb tooth plate portion 12 side, are arranged opposite to each other, and one side 11C of the long sides 11B (the side opposite to the side 12A of the connected tip faces of the comb tooth plate portions 12) is connected.

[0022] The first assembly unit 10 is made of plastic cardboard. Plastic cardboard is a hollow structure, similar to paper cardboard, in which, for example, a pair of flat plastic sheets are connected by a plastic core 12C (see FIG. 1). The core 12C in this embodiment has a large number of continuous concave and convex shapes in the first width W1 direction of the comb-tooth plate portion 12, i.e., along the long side 11A of the base portion 11. Therefore, the comb-tooth plate portion 12 in this embodiment has a plurality of hollow elongated holes H (see FIG. 1) that are multiple hollow elongated holes penetrating the comb-tooth plate portion 12 in the longitudinal direction and are open at both ends, and the comb-plate portions 13A and 13B look like a harmonica when viewed from the side.

[0023] The first assembly unit 10 forms the two pairs of connected comb plate-shaped parts 13A, 13B by cutting the plastic cardboard. At this time, in order to connect sides 12A, 11C of the two pairs of comb plate-shaped parts 13A, 13B, the plastic cardboard is not completely cut from the opposite directions for sides 12A and 11C, but is half-cut so that one plastic sheet is not cut, as shown in Fig. 2(B).

[0024] In the first assembly unit 10, the connected sides 12A, 11C of the two pairs of comb plate-shaped portions 13A, 13B are all valley-folded to form two sets of peaks 14, each of which is formed by connecting portions of the comb tooth plate portion 12. The vicinity of the open ends of the peaks 14 of the hollow elongated hole H constitute insertion holes 16A, 16B into which a connecting member 30, which will be described later, can be inserted. In this embodiment, the insertion holes 16A, 16B have a rectangular cross section.

[0025] As shown in FIG. 3, the second assembly unit 20 has a pair of rectangular frame plate portions 21 and a lattice plate portion 22 into which each of the two sets of peak portions 14 of the first assembly unit 10 is inserted, one by one, into the gap 22A.

[0026] The pair of frame plate portions 21 are formed of a pair of rectangular plate-shaped plate members having long sides with a length L1 equal to the long sides of the aforementioned base plate portion 11. The pair of frame plate portions 21 are disposed so that their long sides face each other with a gap of a third width W3 provided therebetween.

[0027] The lattice plate section 22 is a rectangular plate member having a short side of a second width W2 that is the same as the gaps 15 of the comb tooth plate section 12. A plurality of plate members 23 are arranged in parallel between the pair of frame plate sections 21 with their long sides facing in a direction perpendicular to the long sides of the pair of frame plate sections 21, with a gap of a first width W1 that is the same as the short side of the aforementioned comb tooth plate section 12 along the long sides of the frame plate sections 21. In addition, the lattice plate section 22 is provided with a rectangular plate member 24 so as to divide the gap of the first width W1 in half at equal lengths in a direction perpendicular to the long sides of the frame plate section 21.

[0028] In addition, in this embodiment, a plate member 23 is arranged at one end of the pair of frame plate portions 21, and at the other end, the pair of frame plate portions 21 and plate member 24 protrude from the plate member 23 by a first width W1 that is the same as the short side of the aforementioned comb tooth plate portion 12.

[0029] The first width W1, which is the same as the short side of the comb tooth plate portion 12, refers to a width that allows the short side of the first width W of the comb tooth plate portion 12 to fit into the gap of the first width W1. Also, the second width W2, which is the same as the gap of the comb tooth plate portion 12, refers to a width that allows a plate member of the second width W2 of the lattice plate portion 22 to fit into the gap 15 of the second width W2 of the comb tooth plate portion 12.

[0030] The second assembly unit 20 is made of plastic cardboard, similar to the first assembly unit 10. The second assembly unit 20 is formed by cutting plastic cardboard, and a frame plate portion 21, a lattice plate portion 22, and a plate member 23 are integrally formed.

[0031] The holding shelf 1 is formed by combining the first assembly unit 10 and the second assembly unit 20. Specifically, as shown in Fig. 1, the connected sides 12A, 11C of the two pairs of comb plate-shaped portions 13A, 13B of the first assembly unit 10 are all valley-folded to form two sets of mountain portions 14 in which the connected portions of the comb tooth plate portions 12 become mountain peaks.

[0032] Then, the two sets of peaks 14 of the first assembly unit 10 are inserted one by one into the gaps 22A of the lattice plate portion 22 of the second assembly unit 20, and the second assembly unit 20 is pushed forward to the edge of the base plate portion 11 of the first assembly unit 10, and the comb-tooth plate portion 12 of each of the two sets of peaks 14 of the first assembly unit 10 is rotated about its connected side 12A to expand the base plate portion 11, thereby assembling and forming the holding shelf 1.

[0033] In the holding shelf 1 thus formed, various plate-like materials can be inserted into the gaps 15 of the second width W2 of the comb-tooth plate portion 12 and held in a leaning state. Also, in this holding shelf 1, each of the peaks 14 of the first assembly unit 10 is inserted into the gaps 22A of the lattice plate portion 22 of the second assembly unit 20, so that one side 11C, which is the connecting portion of the two pairs of comb plate portions 13A, 13B, does not shift to one side when the plate-like material is inserted or removed from the gaps 15. Therefore, the holding shelf 1 does not become unstable, and it is possible to stably hold the plate-like material.

[0034] In addition, in the holding shelf 1 of this embodiment, a connecting member 30 shown in Figures 4 to 6 is inserted into adjacent insertion holes 16A, 16B near the open end of the mountain portion 14, and these adjacent insertion holes 16A, 16B are connected to reinforce one side 12A of the half-cut comb tooth plate portion 12.

[0035] 4A and 4B are diagrams showing a connecting member, where (A) is a front view and (B) is a right side view. FIG. 5 is a right side view showing the connecting member of FIG. 4 in a folded state. FIG. 6 is an explanatory diagram showing how to use the connecting member of FIG. 4.

[0036] The connecting member 30 has two columnar portions 31A, 31B that are inserted into the insertion holes 16A, 16B located on both sides of one side 12A of the mountain portion 14. The columnar portions 31A, 31B have cross sections that allow them to be inserted into the insertion holes 16A, 16B into which they are inserted. In this embodiment, the columnar portions 31A, 31B have rectangular cross sections that correspond to the insertion holes 16A, 16B. In addition, one of the columnar portions 31A, 31B, the columnar portion 31A, is formed longer than the other columnar portion 31B (approximately 5 mm longer in this embodiment).

[0037] The columnar portions 31A and 31B are connected by a thin-walled portion 32 that is thin-walled so that the connecting member 30 can be folded as shown in Fig. 5. As shown in Fig. 4, before the connecting member 30 is folded, one side surface 32A of the thin-walled portion 32 is flush with one side surfaces 34A and 34B of the columnar portions 31A and 31B.

[0038] In addition, both ends of the connecting member 30, i.e., the tip of each of the columnar portions 31A and 31B, are provided with a tapered portion 33. The tapered portion 33 may be formed on only one of the columnar portions 31A and 31B. The connecting member 30 is integrally molded from a synthetic resin.

[0039] 6(A), the connecting member 30 having the above configuration is first inserted by inserting the longer columnar portion 31A into the insertion hole 16A of one of the comb-tooth plate portions 12 of the mountain portion 14. At this time, since the tapered portion 33 is provided at the tip of the columnar portion 31A, the columnar portion 31A can be easily inserted into the insertion hole 16A by using the tapered portion 33 as a guide.

[0040] Next, as shown in Fig. 1B, while pushing forward the longer columnar portion 31A, the shorter columnar portion 31B is inserted into the insertion hole 16B of the other comb tooth plate portion 12. At this time, since the longer columnar portion 31A of the connecting member 30 is inserted into the insertion hole 16A adjacent to the insertion hole 16B to be inserted, the position of the shorter columnar portion 31B to be inserted into the insertion hole 16B is restricted and the columnar portion 31B is positioned relative to the insertion hole 16B, facilitating insertion.

[0041] Then, as shown in Fig. 1C, when the two columnar portions 31A, 31B are inserted all the way in, the columnar portions 31A, 31B are fitted into the insertion holes 16A, 16B, respectively, and the comb-tooth plate portions 12 on both sides of the peak portion 14 are firmly connected. After an appropriate number of connecting members 30 are thus attached to the respective comb-tooth plate portions 12 of the peak portion 14, the first assembly unit 10 and the second assembly unit 20 are combined as described above, thereby forming the holding shelf 1 in which one side 12A of the half-cut comb-tooth plate portion 12 is reinforced.

[0042] The first assembly unit 10 and the second assembly unit 20 are not limited to those made of plastic cardboard as in this embodiment, but may be made of cardboard paper, wooden boards, synthetic resin boards, or metal boards. For example, in the case of wooden boards, synthetic resin boards, or metal boards, processing such as cutting out pieces of the above-mentioned shapes from these boards may be performed. When the connecting member 30 is used, an insertion hole may be drilled at the tip of the comb-tooth plate portion 12. Alternatively, when no insertion hole is provided, a hinge may be used instead of the above-mentioned connecting member 30 to connect the comb-tooth plate portions 13A and 13B to each other so that they can rotate freely.

[0043] In the above embodiment, the first assembly unit 10 includes two pairs of comb plate-shaped portions 13A, 13B, and a rectangular plate-shaped plate member 24 is provided on the lattice plate portion 22 of the second assembly unit 20 so that each of the peak portions 14 of the first assembly unit 10 can be inserted into the gaps 22A of the lattice plate portion 22 of the second assembly unit 20, dividing the gap of the first width W1 in half at equal lengths in a direction perpendicular to the long side of the frame plate portion 21. However, it is also possible to configure the first assembly unit to include three or more pairs of comb plate-shaped portions.

[0044] In other words, the first assembly unit includes N (N≧2 (integer)) pairs of comb plate-shaped portions, the N pairs of comb plate-shaped portions being arranged with the tip faces of the respective comb tooth plate portions facing each other and one side being connected, and one side of the end of the base portion of the N pairs of comb plate-shaped portions opposite the comb tooth plate portion side of the base portion of the N pairs of comb plate-shaped portions being arranged opposite one side of the connected tip faces of the comb tooth plate portions and one side of the face opposite the connected tip faces of the comb tooth plate portions, and it is also possible to configure the configuration such that all of the connected sides of the N pairs of comb plate-shaped portions are valley-folded to have N sets of peaks, with each connected portion of the comb tooth plate portions becoming a peak portion at the apex.

[0045] In this case, the lattice plate portion of the second assembly unit is provided so that the rectangular plate member divides the gap of the first width into N portions of equal length in the direction perpendicular to the long side of the frame plate portion. This allows each of the N pairs of peaks of the first assembly unit to be inserted one by one into the gaps of the lattice plate portion, and the connecting portions of the N pairs of comb plate portions do not shift to one side when the plate material is inserted or removed from the gaps, and the holding shelf does not become unstable when the plate material is inserted or removed, making it possible to stably hold the plate material. [Industrial Applicability]

[0046] The connecting member of the present invention is useful, for example, at manufacturing sites for semiconductor devices, liquid crystal panel devices, etc., and is useful as a holding shelf assembly member for assembling and forming holding shelves, etc., from plate-shaped members that can hold plate-shaped materials, etc. required for assembling the device in a leaning position.
