[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting fitting for joining plate members such as a top plate, a side plate, and a curtain plate forming a wooden desk at a right angle and also serving as a wiring duct.

[0002]

2. Description of the Related Art Conventionally, in order to join plate members in a wooden desk, an uneven portion fitted to each other, or a plug shaft fitted over the members is adhered, or an L-shaped metal fitting is used. , Locally combined.

On the other hand, with the recent development and popularization of electric equipment, it is required that the desk itself has a wiring processing function, but few wooden desks have such consideration. Further, in the case where such consideration is taken, a wiring groove is formed in the member, and a detachable cover is attached to this.

[0004]

If the above-mentioned uneven portion between the members or the plug shaft extending between the members is adhered, there is concern about the joint strength.

Further, in the case where the L-shaped metal fitting is used, stress concentrates on this metal fitting, which is disadvantageous in terms of strength and is not good in appearance.

In the case where the wiring groove is provided in the member and the cover is attached to the member, it is troublesome to process the wiring groove, and the thickness of the member is reduced at that portion, so that the strength is lowered, and Because the cover is conspicuous, the aesthetics are also spoiled.

[0007]

SUMMARY OF THE INVENTION The present invention is intended to solve the above-mentioned problems in the conventional ones,
The feature is that it has a length over almost the entire length of the joint portion of the plate-shaped two members to be joined in the wooden desk, and is perpendicular to each other, and holes for set screws are drilled at appropriate places. The end portions of the two side pieces connected to each other with a diagonal piece provided with a longitudinal slot in the middle portion, the side pieces of the right-angled triangular tubular connecting fitting are applied to the connecting portion of the two members. contact,
By attaching the set screw to a plate-shaped member, the two members are connected at a right angle, and the groove is provided on the inner surface with a locking piece that can be engaged with and disengaged from the edge of the oblique piece. It has been blocked.

[0008]

The connecting fitting extends over both members of the two members to be joined and connects them at a right angle.

The connecting fitting has a hollow cylindrical shape, and a cord or the like can be inserted therein.

[0010]

1 is a rear view of a wooden desk in which a curtain plate is firmly fixed to a top plate and a side plate by an embodiment of a wiring duct / coupling metal fitting (hereinafter simply referred to as a connecting metal fitting) of the present invention. FIG. 2 is an enlarged vertical sectional view taken along line II-II in FIG. 1, and FIG. 3 is an enlarged transverse sectional view taken along line III-III in FIG.

The upper edges of the side plates (2) and (2), which have the same depth as the top plate (1), are fixed to both side ends of the top plate (1) by known appropriate means (not shown). Top plate (1) and side plates (2) (2)
Slightly forward of the rear edge of the top plate (1) and the side plate
(2) A curtain plate (3) is provided between the opposing surface of (2) and (2).

The upper and side end surfaces of the curtain plate (3) and the top plate
The stopper shaft (6) is fitted and inserted across a set of a proper number of receiving holes (4) and (5) formed in (1) and the side plate (2) and the contact portion with the curtain plate (3). There is. The stopper shaft (6) is provided with each receiving hole if necessary.
(4) Bonded with (5). The stopper shaft (6) may not be used.

In order to attach the curtain plate (3) to the top plate (1) and the side plate (2) more firmly and securely, the connecting metal fitting (7) of the present invention is provided with the curtain plate (3) and the other side. It is provided so as to straddle the members.

The connecting fitting (7) is a hollow cylindrical member having a right-angled triangular cross section and having the same length as the abutting end surface of the curtain plate (3) against the mating member, and is made of metal, and both side pieces (8) thereof. (8)
A longitudinal slot (10) is provided at the center of the diagonal piece (9) connecting the two.

One of the side pieces (8) (8) of the connecting metal fitting (7) orthogonal to each other is brought into contact with the end of the curtain plate (3), and the other is brought into contact with the top plate (1) or the side plate (2). By connecting the set screw (12) inserted into the hole (11) formed in each side piece (8) to the mating member with which the side piece (8) abuts, the connecting metal fitting (7) is formed. , Curtain plate
(3) and the top plate (1) or the side plate (2) are fixed to each other at the corners where they are joined.

After the connecting metal fitting (7) is attached as described above, the cord (15) is passed through the inner space of the connecting metal fitting, and then the slot (1
The cover (13) is fitted in (0), and the locking pieces (14) and (14) provided on the inner surface of the cover (13) are engaged with the edges of the slot (10).

[0017]

EFFECTS OF THE INVENTION (a) Since the two members are connected by a connecting fitting having a right-angled triangular cross section over the entire length of the joint surface,
The bond strength is high.

(B) Since the connecting fitting is hollow, the cord can be inserted therein, and it is not necessary to separately provide a wiring space in the desk body, and the appearance is good.

(C) Since the slot in the connecting fitting is closed by the detachable cover, the cord inside and the mounting set screw and the like cannot be seen from the outside, and the appearance is good.
