Description

[Detailed description of the invention] [Industrial field of application] The present invention allows leg rods to be attached to table tops etc. in an attractive and strong manner, and is particularly applicable to tables for customer service where design is important. The present invention relates to an effective leg rod attachment device.

[Conventional technology]

The basic structure for attaching leg rods to the top plate of a table, etc. is roughly shown in Figures 6 and 7.
There is a street.

In the case shown in FIG. 6, a bottomed mounting tube 2 is fitted into the upper end of a tubular leg lever 1, and a horizontal catch seat 3 placed on the upper end of the leg lever 1 is attached to a bolt 4. to the mounting tube 2, and attach the peripheral part of the catch 3 to the bottom surface of the top plate 5 with wood screws 6 if the top plate 5 is made of wood, or if the top plate 5 is made of a steel plate or the like. teeth,
It is fixed with a bolt.

In the one shown in FIG. 7, U-shaped connecting fittings 12 fitted to both ends of a horizontal channel-shaped connecting rod 11 are fixed to the upper ends of the inner surfaces of each leg rod 13 with horizontal bolts 14. Accordingly, each leg rod 13
are connected to form a leg frame body, and a top plate 15 placed on the connecting rod 11 is fixed with wood screws 16 or bolts.

[The problem that the idea attempts to solve]

In the case shown in FIG. 6, the strength in the horizontal direction is insufficient, and the leg rods 1 cannot be attached to the side ends of the top plate 5.

In the one shown in FIG. 7, the long connecting rod 11 is exposed on the lower surface of the top plate 15, which is a nuisance and unfavorable in terms of design.Moreover, the weight increases, making movement and transportation difficult.

[Means to solve the problem]

The present invention involves fitting a connecting fitting with a fitting groove that is approximately the same shape as the planar shape of the leg rod from the side near the upper end of the leg rod, and attaching the connecting fitting to the leg rod using a horizontal bolt. A mounting groove of approximately the same shape and size as the above-mentioned fitting groove is provided at key points on the peripheral edge of the top plate of a table, etc., and a mounting groove of approximately the same shape and size as the above-mentioned fitting groove is provided at the peripheral edge of the mounting groove on the bottom surface of the top plate,
Provide a fitting hole into which the connecting metal fitting can fit, fit the upper end of the leg rod and the connecting metal fitting into the mounting groove and fitting hole of the top plate, respectively, and attach the connecting metal fitting to the top plate with a bolt or wood screw from below. The above-mentioned problem is solved by fixing the material to the material.

[Effect]

The device of the present invention has a plurality of bolts fastened between the leg rod and the connecting metal fittings, and between the connecting metal fittings and the top plate, so the strength in each direction is high, and the connecting metal fittings are fastened to the top plate. It looks good because it is buried under the board and is not exposed to the outside.

If necessary, the upper ends of the leg rods can be installed with their upper ends protruding above the top plate.

Further, if the connecting fitting is attached so that one side edge of the leg protrudes from one side end of the connecting fitting, one side edge of the leg rod can also be attached so as to protrude laterally from the side edge of the top plate.

Furthermore, multiple flat plates can be connected laterally with connecting metal fittings to form one wide top plate, making it possible to create tables of various shapes, which was previously difficult.
It can be easily manufactured.

〔Example〕

Figure 1 shows a table to which the present invention is applied, 21 is a top plate with the four corners cut off, 22
is a vertical plate-shaped leg rod which is attached to the cut-out portion of the top plate 21 and has an inward spindle shape divided into two in the longitudinal direction in plan view.

In FIGS. 2 to 4, reference numeral 23 denotes a rectangular connecting fitting that is long in the inside and outside directions for attaching the leg rod 22 to the top plate 21, and from its side end, the shape is almost the same as the planar shape of the leg rod 22. A fitting groove 24 is cut.

25 is a recessed hole for making the connecting fitting 23 lightweight.

The connecting fitting 23 is fitted near the upper end of the leg lever 22 from its ridgeline side, and is fixed to the leg lever 22 by a horizontal bolt 26.

The thick outer portion of the leg rod 22 slightly protrudes outward from the connecting fitting 23.

At the center of each cut-out portion of the top plate 21, a mounting groove 27 is cut from the end face thereof, and is approximately the same shape as the fitting groove 24 and slightly longer than the fitting groove 24.

A fitting hole 28 having the same shape as the connecting fitting 23 is formed on the periphery of the mounting groove 27 on the lower surface of the top plate 21 .

By fitting the upper ends of the leg rods 22 and the connecting fittings 23 into the mounting grooves 27 and the fitting holes 28 of the top plate 21, respectively, and fixing the connecting fittings 23 to the top plate 21 from below with vertical bolts 32, the legs are fixed. The rod 22 is the top plate 21
The outer part and upper end of the top plate 21 protrude slightly from the top plate 21.

FIG. 5 shows another example of a table to which the present invention is applied, in which the top plate 31 includes two first flat plates 31a, 31a in the shape of an isosceles triangle facing inward, and a horizontally long flat plate facing inward. Two trapezoidal second flat plates 31b, 31b
It's getting more and more familiar.

The leg rod 22 is attached to the apex of the first flat plate 31a using the same attachment groove 27 and fitting hole (not shown) as described above, and with a connecting fitting similar to that described above.

A half-split mounting groove 27' and a half-split fitting hole (not shown), which are obtained by dividing the mounting groove 27 and the fitting hole 28, are formed at both ends of the opposing surfaces of the second flat plates 31b, 31b, respectively. In the mounting groove and the fitting hole formed by overlapping the opposing surfaces of both second flat plates 31b, 31b,
The leg rod 22 is attached with a connecting metal fitting, and at the same time, both second flat plates 31b, 31b are connected to each other with a connecting metal fitting.

Also between each first flat plate 31a and second flat plate 31b,
The leg rod 22 is attached in the same manner, and at the same time, both the flat plates 31a and 31b are connected to form the top plate 31.

The planar shape of the leg rod 22 is not limited to the above-mentioned shape.

The present invention is not limited to the top plate of a table, but can also be applied to, for example, the base plate of a display stand or the seat plate of a chair.

[Effect of idea]

In the device of the present invention, the leg rods are attached to the top plate with a large number of bolts via connecting fittings, so
It has high strength in all directions, and the connecting fittings are buried in the bottom surface of the top plate and are not exposed to the outside, so the appearance is good.

If necessary, the upper end of the leg rod can be installed with the upper end protruding above the top plate, the outer edge of the leg rod can be installed with the outer edge protruding laterally than the top plate, or multiple flat plates can be connected laterally using connecting metal fittings. Since it is possible to form a single wide top plate with a complicated shape, the degree of freedom in the design of tables etc. is significantly greater than when using conventional leg attachment devices. It is highly effective when applied to tables for serving customers, which is important.
