DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply line and a signal line necessary for using an OA device such as a personal computer on a top plate of a table, etc. The present invention relates to a table leg, a leg frame and a table having the leg, which realize the storage function of the above with a simple structure without impairing the appearance.

2. Description of the Related Art Conventionally, a large-sized table having at least a wooden top plate is often used as a so-called high-grade conference table. However, the use of solid wood for all components, even for high-grade tables, has become less common due to higher material and manufacturing costs and increased product weight. There are many so-called hybrid types using metal materials in combination.

Conventionally, in a conference table of a type in which a normal top board is supported by a leg, a wiring function is usually hardly considered, and therefore, a personal computer which requires connection of an AC power supply and a communication line on the top board is conventionally used. In order to use various OA equipment, such as the OA equipment, it was necessary to extend the AC power line and communication line from the floor or wall to the table top, but the extended lines hindered walking. And the appearance around the table is impaired. However, in a normal type conference table having four legs or L-shaped legs,
Even if the legs are provided with a wiring accommodating function, they can only have a small-capacity accommodating function and cannot sufficiently cope with the case where a large number of OA devices are used on the top plate. is there.

On the other hand, many conference tables using a metal material as a main component use a plate member having a structure in which a wooden veneer is adhered to the surface of a metal plate in order to give a wooden appearance. However, it cannot be denied that it is inferior to the texture of solid wood. In addition, the material in which a veneer is adhered to a metal plate has limitations in the setting of the cross-sectional shape due to the adhesion of the veneer, and it is difficult to form a free cross-sectional shape like wood, and this is used for conferences that have been completed. This is one of the reasons why the texture and appearance of the table cannot be changed to a satisfactory form.

[0005]

SUMMARY OF THE INVENTION The present invention relates to the problem of the wiring processing capability of the conventional conference table as described above, or the problem of the wiring processing function in a conference table of a type using both a metal material and a wooden material. Combination of metal material and wood agent that combines the advantages of a metal table that is easy to give a structure for wood, and the advantage of a wood-based table that has a solid feeling of wood but has a texture not found in metal It is an object of the present invention to provide a leg and a leg frame structure suitable for a table such as a conference table and the like, and a table provided with the leg and the leg frame structure.

One example of the table according to the present invention is a metal plate having left and right legs L1 and L2 and a pair of legs L1 and L2 made of metal to which a veneer is adhered so that a flat cross-sectional shape becomes an elongated substantially elliptical shape. Connecting member
Since it is formed by the leg frame F connected by Bb and the oval wooden top plate TB fixed on the frame F, the connection relationship between each constituent member and each member will be described below. This will be described with reference to the drawings.

First, the configuration of the legs L1 and L2 will be described mainly with reference to FIG. The legs L1 and L2 shown in FIG. 4 have an elliptical shape whose plan shape is slightly longer. In the present invention, a metal first side plate 1 having a shape obtained by bisecting the outer contour of the leg viewed from a plane on the left and right in FIG. 4 and a second side plate symmetrical to the first side plate 1 are illustrated. A second side plate formed into a cross-sectional shape in which a groove 4 having a flat cross-section is formed by recessing the divided part into substantially L-shape on the inner side of the leg, The third side plate 3 is formed as a basic member. Therefore, the second and third side plates 2 and 3 have a symmetrical shape with respect to the upper and lower sides. Further, when the three side plates 1 to 3 are formed as described above in cross section, or thereafter, a veneer (not shown) is adhered to the surface thereof, and the three side plates are decorated with a wooden appearance.

The above-mentioned three side plates 1 to 3 are connected to the second and third side plates 2 and 3 by attaching a connecting plate 5 serving as the bottom of the groove to the portion where the groove 4 is formed. The plates 2 and 3 are integrated, and in this state, the second and third side plates 2 and 3 integrated with the first side plate 1 are joined to each other at the top and bottom of the two members by so-called stitch-like studs or welding. By forming 6, 7 on the body of the leg L1 (or L2) of the present invention. The body has a core member 1a, 2a, 3a such as a honeycomb material for soundproofing adhered to the inner surface of each of the side plates 1 to 3, and a top plate 8, 9 and 10, and bottom plates 11, 12 and 13 are attached, and a lid member 14 is detachably attached to the entrance of the groove 4 to form an example of the table leg of the present invention. The left and right legs L1 and L2 formed in this way have a veneer attached to the outer surface of the trunk, and the joints 6, 7
This gives the appearance of the body of the leg as if it were entirely made of wood.

The left and right legs L1, L2 formed as described above
Are arranged in parallel with the grooves 4 of both legs facing each other in a direction facing each other, and between the legs L1 and L2, the two plate-like members 15 and 16 serving as horizontal wiring ducts are connected to the left and right sides. A connecting member Bb is formed by mounting and fixing with screws M above the grooves 4, 4 of the legs L1, L2 to form a connecting member Bb.
L1 and L2 are integrated to form a horizontally elongated, substantially gate-shaped leg frame F as a whole (see FIGS. 5 and 6). In the leg frame F, plate members 15, 16 formed in the wiring duct
The upper part is formed to be in contact with the edge of a top plate TB to be described later and to be joined thereto, and is bent at the contact supporting parts 15a and 15b serving as the supporting parts of the detachable lid member 17 of the wiring duct. Along with
The lower portion is bent and formed on bottom plate locking portions 15b and 16b which support and support a bottom plate 18 serving as the bottom of the wiring duct.

On the leg frame F formed by the legs L1 and L2 and the connecting member Bb as described above, one top plate TB can be directly mounted on the upper surfaces of the legs L1 and L2 and the connecting member Bb. In the present invention, the layout of the top plate and the support of the split top plate are devised in the present invention, and this will be described with reference to FIGS.

7 to 9, reference numerals 19, 20, and 21 denote legs L1.
On the upper surface of the top plates 8 to 10 in (or L2), here are the top plate support arms made of three channel members, mold members, and the like fixed by screws M in a direction parallel to the connecting member Bb. Although not shown, the intermediate arm 21 of the three arms 19 to 21 is bent downward at the near side in FIG. 7 and the bent portion is positioned and fixed in the groove 4 of the legs L1 and L2. Sometimes. The reason for providing the top plate support arms 19 to 21 on the legs L1 and L2 is that, in the present invention, a flat elliptical top plate TB to be mounted and supported on the leg frame F is connected to a substantially semi-arc-shaped portion (left and right sides) described later. , Right side end top plate) and an intermediate rectangular portion (intermediate top plate).

That is, the tabletop TB of the table of the present invention exemplified in FIGS. 1 to 3 and FIG. 10 has a leg frame F whose whole planar shape sufficiently covers the support arms 19 to 21 provided thereon from above. The top plate TB is not a single plate, but the first side member 1 and the second and third side members 2 of the legs L1 and L2 in the leg frame F. On the line passing through the joints 6 and 7 with 3, the left and right side top plates 22 and 23 and the middle top plate 24 are divided, and the middle top plate 24 is connected to the legs L 1 and L 2. It is divided into two front and rear top plates 24a and 24b with the member Bb interposed therebetween. In this embodiment, each of the divided top plates 22, 23, and 24 has a groove for fitting the support arms 19 to 21 on the back surface thereof.

Of the top plates 22 to 24 divided as described above, the middle top plates 24a and 24b are provided with the grooves on the back surface on one side of the support arms 19 to 21 (the inside of the legs L1 and L2). Part), and by tightening a set screw M from a hole on each support arm 19-21 side, the left and right legs L via the support arms 19-21.
1, and will be fixed to the upper surface of L2 and the support arms 19-21. In the illustrated example, first, the divided intermediate top 24
a and 24b are attached to the leg frame F with the connecting member Bb serving as a wiring duct positioned at the center of the abutment.
Place the right top plates 22 and 23 in the grooves on the
Attach to left and right legs L1 and L2 via. At this time, the butting surfaces of the intermediate top plate 24 and the left and right top plates 22 and 23 are also connected by the top plate connecting bolts B and the connecting rods C.

In the present invention, the top plate TB is divided into the above-described left and right end top plates 23, 24 and the intermediate top plate 24 as shown in FIG. This is because it is easy to form a table provided with a long top plate in which two or more intermediate top plates 24 are connected to one table.

In the table of the present invention in which two or more intermediate top plates 24 are continuously added, the configuration of the middle leg L3 is different from the configuration of the left and right legs L1 and L2 described above. . That is, although the details of the middle leg L3 are omitted, both the left and right sides of the leg L3 are formed by the second and third side members 2 and 3 in the legs L1 and L2, and the left and right sides of the leg L3 The legs having the grooves 4 are used.

In the example described above, the grooves 4 of the legs L1, L2
The wiring ducts formed by the connecting members 15 and 16 connected to the groove 4 are formed in only one line for one leg frame F. In the present invention, the vertical grooves are formed for one leg L1 and L2. By providing at least two connecting members 4 and connecting connecting members 15 and 16 to the opposed grooves 4 of the left and right legs L1 and L2,
It is possible to form two or more rows of side-by-side wiring ducts.

[0024]

The leg for a table of the present invention, the leg frame using the leg, and the table are as described above.
By providing a groove with a detachable lid member formed on the facing surface of the left and right legs, wiring that can be raised from the floor can be housed in the above-mentioned premises and guided to the top plate side. Since the grooves of the left and right legs are formed on a substantially gate-shaped leg frame by attaching a connecting member serving as a wiring duct to an upper portion thereof, the wiring standing up in the grooves is directly used as a top plate. Can be introduced into the wiring duct formed along the length of the duct, so that the wiring can be drawn out on the top plate from any place in the duct, or a connector such as an outlet can be optionally installed in the duct. It becomes possible to arrange in.

In the present invention, the wiring for passing through the inside of the leg frame can be almost completely concealed from the outside as described above, so that not only the appearance is good but also the vertical grooves of the left and right legs. In addition, since the capacity of the horizontal wiring duct formed by the connecting members of the legs is considerably large, even a large amount of wiring can be accommodated with a sufficient margin.

Also, in the present invention, since the appearance of the legs appears to be formed of a wood-based material, the appearance is combined with the wood-based top plate, so that a large conference table can be used as if it were a solid wooden board. It looks as if it is made of wood, so the overall appearance is very good.

Since the present invention is as described above, a large conference table showing a wooden appearance is mainly made of metal, but is formed by using a metal plate with a veneer attached as a decorative material. It is very useful when applied to a table.
