Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partitioning device for combining a plurality of partition boards to be used as a partition wall in a room or a partition for an exhibition, etc., and an extruded member for a joint member which is a part of the partitioning device. It is about.

[0002]

2. Description of the Related Art It is known to use a plurality of partition boards which are used independently for partitioning a room or an exhibition at a room. For example, two partition boards may be connected in an L-shape, or three partition boards may be combined in a U-shape, a T-shape, or the like to be self-supporting. In the case where a plurality of partition boards are used in combination in this way, it is known that a dedicated metal fitting is used as a joining structure of the partition boards.

For example, there is a method of connecting a plurality of partition boards by connecting upper and lower corners of each board with dedicated metal fittings. In this case, a tool such as a spanner or a screwdriver is difficult to use in the lower corner, so that a metal fitting is fixed to only one partition with a bolt, and the other partition is connected to this metal fitting by being engaged from above. The upper corners of both partitions are fixed to each other using a metal fitting and a bolt.

[0004]

Problems with the prior art In this conventional structure, it is necessary to use a dedicated metal fitting for each joint of the partition. For example, when two partition boards are assembled in an L-shape and when they are connected linearly, the shape of the bracket differs.

When three partition boards are assembled in a T-shape or at 120 ° intervals, a special bracket is required when assembling four partition boards in a cross shape. For this reason, the types of metal fittings have increased, and assembling work has been troublesome. On the contrary, it was troublesome to disassemble.

Further, in order to fix the dedicated metal fitting to the partition board, it is necessary to fix a metal fitting for bolting the metal fitting to the partition board side. For this reason, the periphery of the partition board usually needs to be made of metal, which significantly increases the weight.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is not necessary to prepare a dedicated metal fitting which is different for each connection portion of a partition board, and the number of members used for connection is reduced, so that assembly and assembly can be performed.

And a plurality of joint members having second engagement portions having a constant cross-sectional shape, and the second engagement portions of the appropriate number of joint members are respectively engaged with the first engagement portions of the side edge covers of different partition boards. The partition device is characterized in that a plurality of partition boards are connected to the center pole.

The side edge cover and the joint member can be manufactured by extruding a hard synthetic resin such as polyvinyl chloride. These can also be manufactured by extrusion molding of a metal such as an aluminum alloy. The center pole can also be made by extrusion molding of a synthetic resin, but may be made of metal such as steel.

Preferably, the center pole has a circular cross section. If the cross section is circular, the mounting angle of the joint member about the center pole can be set freely, and the joining angle of the partition board can be set freely. However, the joining angle of the partition board is 120
If the angle is fixed at 90 ° or 90 °, a center pole having a hexagonal or rectangular cross section can be used.

If the center pole has a circular cross section, the joint member has a cylindrical portion fitted on the outer periphery of the center pole and a second engaging member having a T-shaped cross section protruding along the axial direction on the outer surface of the cylindrical portion. And a structure having a portion.

It may be made to engage so that it may be pinched.
In this case, since the joint member can be fitted to the center pole from the radial direction, it is convenient when the center pole is long and the upper end is close to the ceiling.

As the partition board, a board made of a cardboard or plastic honeycomb board having a large number of small holes having a hexagonal cross section penetrating in a thickness direction thereof and using a honeycomb board made of plastic as a core material is suitable. Further, a cardboard made by stacking and joining a plurality of cardboards, or a cardboard made of foamed resin may be used. In these cases, sufficient strength can be obtained, and it is suitable for weight reduction.

A second object of the present invention is to have a cross-sectional shape consisting of an annular portion and a second engaging portion having a T-shaped cross-section protruding from the outer surface thereof, and cut to a predetermined length. 2. An extruded material for a joint member used as the joint member in 2. For the same purpose, a joint member having a substantially Ω-shaped cross section and having claw-shaped second engaging portions at both ends of the substantially Ω-shaped member, and cut into a predetermined length to be used as a joint member according to claim 4. It can also be achieved by an extruded material for use.

FIG. 1 is a front view of an embodiment of the present invention, FIG. 2 is a sectional view taken along the line II-II, FIG. 3 is a sectional view taken along the line III-III also partially omitted, and FIG. FIG. 5 is an exploded perspective view showing an arrangement example of members, and FIG. 5 is a cross-sectional view near a center pole. In this embodiment, when viewed from the front (FIG. 1), one or more partition boards 10 are connected at right angles to the central rear surface of four partition boards 10, and are combined in a substantially T-shape in plan view.

The partition board 10 has a honeycomb board as a core material. Here, the honeycomb board is a plate having a large number of hexagonal small holes in the thickness direction, is made of a cardboard or a plastic thin plate, and is lightweight and has sufficient strength. Appropriate surface materials are stuck on both sides and the peripheral edge of this honeycomb board to give sufficient surface hardness.

A cover 12 is fixed to the periphery of the partition board 10 by bonding or the like. That is, the cover 12 is made by extruding a synthetic resin so as to have a constant cross section as shown in FIG. Here, as the synthetic resin, polyvinyl chloride (PVC) or the like having a sufficient curing strength is suitable.

As shown in FIG. 3, the cover 12 has a cavity 14 parallel to the end face of the partition board 10, and a pair of tongues 16, 16 extending along both sides of the board 10. The cover 12 is directly fixed to the upper edge and the lower edge of the board 10 using an adhesive or the like.

On both side edges of the board 10, the cover 12
A side edge cover 12A having substantially the same cross-sectional shape as above but having a slit 18 along the length direction on its outer surface is fixed. The side edge cover 12A is extrusion-molded so as to have a slit 18 in the center in the width direction along the length direction, and the cavity 14 and the slit 18 form a substantially T-shaped first engagement portion 19.
(FIG. 2).

Reference numeral 20 denotes a center pole, which is a metal pipe or an extruded product of a synthetic resin such as PVC. The center pole 20 has a circular cross section, and its lower end has a base 2 made of a synthetic resin such as PVC or a metal.
2 is positioned by engaging with a concave portion or a convex portion provided in 2.

Reference numeral 24 denotes a joint member, which has a cylindrical portion 26 having an inner diameter through which the center pole 20 passes, and a second engaging portion 28 having a T-shaped cross section protruding from the outer surface of the cylindrical portion 26 along the axial direction. And This joint member 24 is
It is an extruded product of a hard synthetic resin such as VC or a metal, and is cut into an appropriate length for use. That is, when a predetermined number of joint members 24 are sequentially fitted to the center pole 20, the length of the joint members 24 connected to each other matches the height dimension of the partition board 10.
The length and number of each joint member 24 are determined.

Reference numeral 30 denotes a spacer fitted to the lowermost portion of the center pole 20, which determines a gap between the board 10 and the floor 32. The spacer is a cylinder having the same diameter as the cylindrical portion 26 of the joint member 24, and is made of a hard synthetic resin such as PVC or a metal. Numeral 34 denotes a disk-shaped stopper, which is fitted to the center pole 20 from above and mounted on the spacer 30. The outer diameter of the stopper 34 is larger than the outer diameter of the spacer 30.

The connection of the partition board 10 is performed as follows. First, attach the lower end of the center pole 20 to the base 22.
And the spacer 30 and the stopper 34 are dropped from above while being fitted thereto. Then, the connection edge of the partition board 10 connected by the center pole 20 is held facing the center pole 20. At this time, the corner of the lower edge of the board 10 is engaged with the upper surface of the stopper 34 and positioned (see FIGS. 4 and 5).

In this state, the joint member 24 is fitted with the cylindrical portion 26 fitted to the upper end of the center pole 20.
The second engaging portion 28 is connected to the first engaging portion 1 of one board 10.
9 (14, 18). Then, the joint member 24 is connected to the center pole 20 and the first engagement portion 19.
Lower while engaging with (14, 18). The next joint member 24 fits the cylindrical portion 26 to the center pole 20 and lowers the second engaging portion 28 while engaging the first engaging portion 19 (14, 18) of the other board 10.

In this manner, the plurality of joint members 24
Are sequentially different from each other in the first engagement portions 19 (14, 1) of the board 10.
8). Preferably, the number of joint members 24 engaging with each board 10 is at least two.
Therefore, the number of the joint members 24 divided for one center pole 20 is desirably set to an integral multiple of the number of the partition boards 10 connected by the center pole 20, and is particularly preferably set to twice or more. For example, if three boards 10 are to be connected, six or more joint members 2
4 is recommended.

After connecting the plurality of boards 10 to the center pole 20 with the predetermined number of joint members 24 in this manner, a cap 36 is attached to the upper end of the center pole 20. The cap 36 prevents the joint member 24 from coming off upward, as is apparent from FIG.

In order to disassemble the thus assembled partition, a reverse process to that at the time of assembling may be performed. That is, the cap 36 may be withdrawn upward, and the joint member 24 may be withdrawn upward from the top.

In this embodiment, since the center pole 20 has a circular cross section, the angle of the joint member 24 can be arbitrarily set, and the coupling angle of the partition boards 10 to be connected can be freely changed.

[0030]

FIG. 6 is a sectional view showing another embodiment, and is a sectional view taken along the line II-II in FIG. In this embodiment, the joint member 124 is formed to have a substantially Ω-shaped cross section, and claw-shaped second engagement portions 128 are formed at both ends of the cross section.

The side edge cover 112 of the partition board 100 has a pair of claw-shaped first engaging portions 119 which are engaged with the second engaging portions 128 from outside. That is, the second engaging portion 128 has a claw that protrudes outward, and the claw that protrudes inward of the first engaging portion 119 engages with this claw.

Therefore, the joint member 124 can be fitted to the center pole 120 by pressing the Ω-shaped opening into the center pole 120 from the radial direction. Further, by pressing the first engaging portion 119 of the partition board 100 from the side against the second engaging portion 128 of the joint member 124, the two can be joined.

As described above, according to this embodiment, since the joint member 124 can be detached from the side without being fitted from the tip (upper end) of the center pole 120, the assembling / disassembling operation can be easily performed even when the ceiling is low. It is possible to do.

[0034]

As described above, according to the first aspect of the present invention, the center pole and the connecting edge of the partition board are connected by a joint member having a constant cross-section divided in the longitudinal direction of the center pole. The connection angle of the partition board can be changed by changing the angle of the member.

Therefore, the same joint member can be used for changing the connection angle and the number of connected sheets. For this reason, it is not necessary to prepare different metal fittings and members for each connection portion, and the types of members used can be reduced.
In addition, assembly and disassembly can be easily performed without using a special tool. Further, since it is not necessary to bolt a special metal fitting to the partition board, it is not necessary to fix a metal fitting for fixing the bolt to the partition board side, and the weight can be reduced.

The side edge cover and the joint member can be made of extruded synthetic resin. In this case, the productivity is good and the production cost can be greatly reduced. The center pole may be manufactured in the same manner.

The center pole has a circular cross section. The joint member has a cylindrical portion fitted on the outer periphery of the center pole, and a second engaging member having a T-shaped cross section protruding along the axial direction on the outer surface of the cylindrical portion. And a shape having a portion. In this case, a first engaging portion having a substantially T-shaped cross section with which the second engaging portion is engaged is provided on the side edge cover.

The joint member has a substantially Ω-shaped cross section.
Claw-shaped second engaging portions may be formed at both end portions of the mold.
In this case, the side edge cover is formed with a claw-shaped first engaging portion that engages with both second engaging portions from outside (claim 4).
According to this joint member, the center pole can be fitted from the side, and the first and second engaging portions can also be engaged from the side. Therefore, there is no need to attach and remove the joint member from above the center pole.
Decomposition becomes easy.

As the core material of the partition board, a honeycomb board through which a large number of small hexagonal holes penetrate in the thickness direction can be used. Since the honeycomb board is lightweight and has high strength, workability in assembling and disassembling is further improved. Instead of the honeycomb board, a cardboard cardboard made by stacking a plurality of cardboards or a foamed resin plate may be used.

According to the sixth and seventh aspects of the present invention,
A long extruded member used to make the joint member can be obtained. That is, by cutting this extruded member to an appropriate length, a joint member can be easily produced.
