Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a plurality of top plates connected or connected in the length direction and depth direction (hereinafter also referred to as "vertical and horizontal connected top plates"). The present invention also relates to a support device for a connecting top plate that does not require leg members on the lower surface of the connection.

[Conventional technology]

Recently, counters and the like have been proposed in which the top plates of tables, counters, etc. are connected in the length direction, and no leg members are provided on the lower surface of the connection (Japanese Patent Application Laid-open No. 57-96609).

Conventionally, when forming a long counter for visitors, etc., the counters, etc. related to the above proposal were made by joining and arranging multiple counters formed with fixed-sized top plates, so the joints This was developed in order to improve the problem that the leg members overlap, making it difficult to utilize the inside of the counter (customer service side) effectively. This eliminates the need for leg members on the lower surface of the connection.

[Problem that the invention seeks to solve]

In the counters, etc. related to the above proposal, the problem with the connecting structure in the length direction of the top plates has been solved, but the top plates connected in the length direction are connected in the depth direction. There is no problem with that.

In other words, if the above-mentioned top plates that are connected in the length direction are also connected in the depth direction, and no leg members are provided on the bottom surface of the top plate, it is possible to create a vast top plate without leg members on the bottom surface of the top plate. It is possible to provide a conference table or the like having a board surface, which brings many practical advantages.

For example, the top plate of a table or other device with a vast top surface cannot be formed as a ``one-piece'' piece due to standards regarding the size of the material, so it must be of the bonded type. It was necessary to support the joint with leg members. but,
If leg members are indispensable on the lower surface, they cause inconveniences such as getting in the way during use and restricting the design of the table or the like.

Also, if you temporarily convert a vast top plate into a so-called "one piece"
Even if it can be formed into a plastic container, it takes up a lot of space to transport and store, making it difficult to handle.

[Means for solving problems]

Therefore, the present invention is designed to firmly connect a plurality of top plates connected in the length direction also in the depth direction, and to connect the plurality of top plates connected in the length direction and the depth direction without disposing leg members on the lower surface of the connection part. The purpose of this device is to provide a support device for connected top plates that can be formed into a table or the like by supporting connected top plates. In addition, connecting rods penetrating through the hollow top plate outer skin in the longitudinal direction are provided inside the hollow top plate outer skin whose longitudinal ends are formed as connecting parts, and the interior is enriched by injecting and foaming a synthetic resin or the like. By aligning the two formed unit top plates facing each other in the depth direction, and embedding and fixing the side connecting plates in the connecting portions at both ends of the two facing top plates,
Two top plates are connected and fixed in the depth direction to form a connected top plate in the depth direction, and two or more sets of connected top plates in the depth direction are arranged in the length direction of the top plates, and each top plate is By tightening both outer ends of the connecting rod penetrating through the inside of the top plate with nut members, the top plates connected in the depth direction are formed into a vertically and horizontally connected top plate that is tightly connected in the length direction.

Although a straight connecting plate 4 is used in this embodiment, a connecting plate 4 whose portion facing the gap 5 has the same cross-sectional shape as a beam member 6 described later may also be used.

Therefore, the top plates 1, 1 connected in the depth direction are
For example, two sets of these are arranged in the length direction of the top plate 1 as shown in FIG. 3, and are connected by the connecting rods 3 facing each other.

Here, an end nut member 3c is screwed onto the threaded part 3a of the connecting rod 3 located on the left end side of the figure via a washer-like end fitting 3b, while the opposing threaded parts 3a, 3a are connected by a connecting nut member 3d. After this, the threaded part 3 of the connecting rod 3 located on the right side of the figure

Further, the upper edge of the vertical wall of the groove-shaped beam member 6 is bent inward in the horizontal direction, and is formed at a contact surface 6b with the lower surface of the top plate.

Therefore, the width of the groove of this beam member 6 is the same as that of the top plate 1,
The gap 5 is wider than the gap 5 formed during the depth direction connection in step 1.

Note that a channel-shaped edge member 6c is attached to the front edge of the abutment surface 6b. As will be described later, this edge member 6c is adapted to fit into a gap 5 between the top plates 1 and 1 connected in the depth direction.

The beam members 6 are connected in the following manner.

That is, between the two connecting plates 7 provided on both longitudinal sides of the member 6, a connecting rod 8 similar to the connecting rod 3 of the top plate 1 is inserted into the hole 7a of the connecting plate 7, A washer-like end fitting 7b is applied to the side end, and the end nut member 7c is tightened from the outside to the screw of the connecting rod 8, and the connecting plates 7 are connected to the connecting rods 8, 8 facing each other.
By screwing the connecting nut member 7d into the threaded portions 8a, 8a, the beam member 6 is connected as shown in FIG.

In addition, the connecting portion between the connecting plates 7 is further connected to the connecting side 6.
In hole 61a of a, insert washer 7g or washer 7h.
The connected state is reinforced by bolts and nuts 7e and 7f.

In this way, here, the two beam members 6 are tightly connected by the connecting rod 8, as in the case of the longitudinal connection in the top plate 1.

The top plate 1 connected in the depth direction and the length direction as described above and the beam member 6 connected in the length direction are, in this embodiment, panel-shaped leg members as described below. 9 and assembled into a table shape. The configuration of the leg member 9 here is as follows.

As shown in FIG. 2, the panel-shaped leg member 9 has an end fitting 3b attached to the outer surface of the connecting top plate 1 on its inner side, and an end fitting 3b attached to the outer side of the connecting beam member 6. A receiving portion 9a for receiving the end fitting 7b is formed therein, and a screw hole 9b facing the hole 61a of the connecting side 6a located on the outer surface of the connecting beam member 6 is formed.

On the other hand, the end fittings 3b, 7b are formed with mounting holes 31b, 71b for fixing them to the receiving part 9a of the leg member 9. Therefore, on the receiving part 9a side of the leg member 9, Above mounting holes 31b, 71
A screw hole 9c corresponding to b is provided.

The assembly of the connecting top plate support device according to the present invention is performed in the order shown in FIGS. 2 to 4.

First, in FIG. 2, two beam members 6 are connected, and the distal end side (left side in the figure) is connected and fixed to the leg member 9. At this time, the rear end side (right side in the figure) of the connecting beam member 6 is supported by a temporary stand S to facilitate assembly.

Next, in FIG. 3, the leading end side of the connecting beam member 6 is connected to the leg member 9, and the top plate is connected only in the depth direction to the upper surface of the beam member 6 whose rear end side is supported by a temporary stand S. 1, and while connecting the two sets of top plates in the longitudinal direction, the tip side (left side in the figure) is connected and fixed to the leg member 9.

At this time, the connection portion in the depth direction of the connection top plate and the beam member 6 have a relationship as shown in FIG.

That is, the front end side of the top plates 1, 1 forming the gap 5 in the connecting top plates is the contact surface 6b of the upper part of the beam member 6.
The edge member 6c attached to the front edge of the support surface 6b fits into the gap 5 between the front end surfaces of the top plates 1,1.

Here, the top plates 1, 1 connected in the depth direction
are also connected in the length direction, so the connecting plates 4 in the depth direction are in a state where they are overlapped at the longitudinal connecting surfaces of the top plates, as shown in FIG.

Therefore, the overlapping connection plates 4, 4 are sandwiched from above and below by plate-shaped fastening fittings 10, 11 shown in FIG. 5, and both 10, 11 are tightened with a countersunk screw 10a to form a tight bundle.

In this case, since the tightening fitting 11 is formed in a length that reaches the back surface of the abutting surface 6b formed on the beam member 6, the lengthwise connecting portion of the beam member 6 and the ceiling are connected by this tightening. The longitudinal connecting portion of the plate 1 is bound and integrated.

In addition, by fixing the connecting side 6a of the beam member to the other leg member 9, which also functions as an end panel, the connecting top plate is connected in the width direction and the depth direction, and is assembled into a table here. .

In FIG. 4, reference numerals 12 and 13 are wiring receivers disposed inside a groove formed by the gap 5 of the top plates 1 and 1 and the groove of the beam member 6, and the upper and lower wires are placed in the groove. Can be installed in two stages.

Reference numerals 14 and 15 designate a removable cover and a pen tray that are attached to the edge member 6c of the beam member 6.

Therefore, the groove portion of the beam member 6 can function as a wiring duct, a tray mounting portion, or the like. Therefore, if a member with a different shape and structure is attached, it can be used as a desk lamp, telephone, etc.
It is possible to attach an installation table for CRT, etc., a support arm, etc.

Furthermore, if a rail section along the beam member 6 is formed on the inner wall of the groove section formed by the beam member 6, and a cart-like platform is provided which runs and moves along the groove section while being guided by the rail section, It is possible to easily move a CRT, etc. along the length of the top plate.

The above embodiment describes an example of a support device for forming a table by connecting four unit-shaped top plates in the depth direction and length direction. The top plate is the smallest unit of the connected top plate in the depth direction and the length direction, and therefore, in the device of the present invention, the connected top plate of the above embodiment can be connected in the depth direction or length direction, or in the depth and length direction. Of course, it can also be applied to connected top plates that are connected together.

In addition, when the number of connections of the top plate increases in the depth direction, there will be a plurality of connecting beam members, and the width and structure of the panel-shaped leg members will also be adjusted accordingly.
Further, when the length increases, the connecting beam members are connected to a corresponding length.

Furthermore, unit top plates 1 in a connected manner as shown in FIG. 6 can also be supported by the apparatus of the present invention.

〔Effect of the invention〕

The present invention is as described above, and includes a beam member that can tightly connect top plates that are connected in the depth direction and length direction in the length direction according to the connection length of the top plates, and a beam member that can connect the top plates that are connected in the depth direction and the length direction. Since the fixed support is provided by the leg members that are firmly fixed and supported, it is possible to easily form a support device according to the number of top plates to be connected. Since the parts are fixed and integrated with the beam member, the connecting top plate is fixedly supported not only at the side ends but also at the middle part, and extremely high rigidity can be achieved as a whole.

Therefore, the present invention is extremely useful as a top plate support device for a table or the like having a top plate with a vast area.
