Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to furniture, and more particularly to so-called system furniture.

[Prior Art] Conventionally, furniture in which a top plate is supported by boxes, chests, other storage furniture, or supporting legs has been known.

[Problems to be solved by the invention] In this case, the relative position of the storage furniture or the like with respect to the top plate cannot be arbitrarily changed, and, for example, two types of storage furniture located at both ends of the top plate cannot be installed. It was impossible to replace it. In other words, the top plate and the storage furniture were connected by screwing screws into the screw holes provided in both, and unless the screw holes match, it is impossible to attach them with screws. Because.

[Means for Solving the Problem] In order to solve this problem, in the present invention, a groove extending in the longitudinal direction is provided on the lower surface of a long top plate, and a rail is provided in the groove, and a lower surface of the rail is provided. Arranged so as to be located above the lower surface of the top plate, a box for supporting the top plate, chest, other storage furniture, or a hole is provided in the top plate of the supporting leg,
One of the bolts or nuts having a head is projected downward from the top plate by inserting the head into the rail, and the other of the bolts or nuts is inserted from below the top plate, By screwing a bolt and a nut, the storage furniture or the supporting leg can be positioned at an arbitrary position in the longitudinal direction of the top plate in a state where the lower surface of the top plate and the upper surface of the top plate are in contact with each other.

[Operation] Brings storage furniture and supporting legs to any position in the longitudinal direction of the top plate. Bolts or nuts projecting below the top plate, and bolts or nuts other than those mentioned above are inserted into the holes provided in the top plate of the storage furniture or the supporting leg from below and screwed together. Secure the top plate and storage furniture.

The storage furniture or the supporting legs can be moved without separating the top plate from the storage furniture and the like, with the bottom surface of the top plate and the top surface of the top plate of the storage furniture or the like being in contact with each other.

[Example] 10 is a long top plate, and a groove 12 is formed on the lower surface thereof along the longitudinal direction. Reference numeral 14 denotes a rail, which is arranged in the groove 12 with both ends of the groove 12 left. The rail 14 is made of a C-shaped member, and as shown in FIG.

Reference numeral 18 denotes a bolt, the head 20 of which is engaged with the rail 14 so as to be slidable in the longitudinal direction.

The head 20 of the bolt 18 is preferably square or rectangular, and in this case, when the nut described later is tightened from below, the bolt 18 does not rotate, so that smooth tightening can be performed.

A rubber packing 22 is adhered to the lower surface of the head 20 of the bolt 18. As a result, when the nut is tightened from below, there is no looseness due to the elastic force of the rubber. Especially when the rubber packing is thick, both side edges of the packing in the horizontal direction bulge outward due to the tightening of the nut, and the rail 14
The inner surface of the leg portion 15 can be pressed, the bolt is less loosened, and the bolt 18 can be prevented from moving in the longitudinal direction of the rail 14.

The rail 14 is attached to the top plate 10 as follows. Apply an adhesive to the outer peripheral surface of the rail 14 or the inner peripheral surface of the groove 12,
Press the rail 14 into the groove 12 (The width of the groove 12
It is slightly smaller than that of. At this time, rail 14
While the outer peripheral surface of the rail bites into the groove 12, the rail 14 is securely attached to the groove 12 by the adhesive. Further, the screw 24 is inserted into a screw hole 26 provided at a required position in the longitudinal direction of the rail 14 and tightened.

The hole 26 for inserting the screw 24 is counterbored. In other words, the head portion of the screw 24 is formed in a taper shape that becomes smaller in diameter toward the upper side, and therefore, the head portion of the screw 24 fits within the wall thickness of the upper plate of the rail 14 and does not project downward. The movement in the direction is smooth.

Further, as shown in FIG. 2, the rail 14 is a lower surface of the top plate 10.
Since it is located slightly above 11 and is completely embedded in the top plate 10, it is possible to firmly fix it to each other without any gap between the top plate and the storage furniture to be described later. Is.

The bolt 18 engages with the rail 14 by inserting its head 20 upward from the end 13 of the groove 12 and moving it laterally as it is.

Reference numeral 30 is a box that supports the top plate 10. The top plate 32 of the box 30 has a long hole 34 extending in the same direction as the rail longitudinal direction.

36 is a nut, and is a tubular portion 38 having a threaded portion inside.
And a flange 40 provided at the lower end thereof. 42 is a cosmetic cap that fits on this flange. Although not shown, a cross-shaped groove is provided on the lower surface of the flange 40 of the nut 36. Therefore, it can be tightened with a minus driver, a plus driver, a square wrench, a coin, or the like.

If the tubular portion 38 of the nut 36 is formed to have a diameter slightly smaller than that of the elongated hole 34, it can be easily inserted and is convenient. Further, it is preferable that the length of the nut 36 is made slightly smaller than the thickness of the top plate 32 so that it does not project from the upper surface of the top plate.

When the hole for inserting the nut 36 is formed in a long hole as in the illustrated embodiment, it is preferable because the relative position between the top plate and the box can be finely adjusted. However, instead of this long hole, a normal round hole may be provided, and in some cases, a long hole orthogonal to the rail longitudinal direction may be used.

Although illustration is omitted, when a spring washer or a resin is fitted between the flange 40 of the nut 36 and the lower surface of the top plate 32 of the box, the nut 36 is securely tightened. Also,
Instead of this, a ring-shaped rubber may be attached to the upper surface of the flange 40.

44 is a hole concealing component. When the top plate 10 and the box 30 are not joined and the top plate is removed, the long hole 34 is closed by this component 44. Therefore, the upper portion 46 of the component 44 preferably has the same shape as the slot 36, and the upper portion 46 preferably has the same thickness as the top plate 32.

In the illustrated embodiment, the bolt 18 is fitted into the rail 14 and the nut 36 is inserted from below the box top plate 32 to above.
Instead of this, the nut 36 is arranged above and its head is engaged in the rail, and on the contrary, the bolt 18 is put in the box and inserted into the hole 34 of the top plate 32 from below. Both may be screwed together. In this case, it is preferable to make the flange of the nut, that is, the head of the nut square or rectangular so that the nut does not rotate in the rail.

Third example of the use of the connection structure of the top plate and the storage furniture of the present invention
Shown in Figures and 4.

In FIG. 3, 30 is a box similar to that in FIG. 2, 50 is a chest, and 52 is a double-sided box.

In FIG. 3, a box 30 and a double-sided box 32 are arranged at both longitudinal ends of the top plate 10, and a chest 50 is in contact with the box 52. In this case, box 30
In the space between the chest and the chest 50, an operator can use this as a desk or the like. On the other hand, in the case of FIG. 4, the chest 50 is slid to a position intermediate between the boxes 30 and 52. In this case, two workers can be used as desks in the left and right spaces of the chest 50.

As is apparent from FIGS. 3 and 4, in the present invention, for example, the chest 50 can be slid along the longitudinal direction of the top plate and fixed at any position. Also,
For example, if you replace boxes 30 and 52 in Figure 3,
The position where the top plate and the box are screwed is not fixed, and the position can be changed to any position because it can be brought to any position.

In the above embodiments, the top plate is supported by furniture that can be housed inside a box, chest or the like, but instead of this, the top plate may be supported by simple supporting legs. In FIG. 5, reference numeral 60 denotes an inverted U-shaped supporting leg, and a hole 34 for a nut is inserted through this top plate 62. Therefore, it is possible to bring the support leg 60 to an arbitrary position in the longitudinal direction of the top plate and support the top plate by the support leg 60.

In this invention, the top plate can be widely used as a desk, a table, a work table, a dining table, or the like.

[Effect of the Invention] As described above, according to the present invention, the top plate and the storage furniture can be fixed to each other with bolts and nuts at arbitrary positions. It can be replaced and attached to the top plate. It is also possible to slide a storage furniture such as a box or a chest or a supporting leg along the top plate to bring it to an arbitrary place.

The storage furniture can be moved without separating the storage furniture and the top plate in a state where the upper surface of the top plate and the lower surface of the top plate of the storage furniture are in contact with each other, and the arrangement of the storage furniture can be easily changed. is there.

Further, since the rail is completely embedded in the groove provided on the top plate, the groove and the rail are hard to see from the outside, and the appearance is good. Further, by embedding the rails in the top plate, there can be no useless space between the top plate and the storage furniture, and accordingly, a wide space can be secured inside the storage furniture.
