Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connecting fitting for joining plate members such as a top plate, a side plate, a curtain plate or the like, or leg rods, etc., which constitute a wooden desk, at a required angle, and which also serves as a wiring duct.

[0002]

[Prior Art]

 Conventionally, in order to join plate members to each other in a wooden desk, or plate members and leg rods, etc., an uneven portion that is fitted to each other, or a plug shaft that is inserted between members is adhered, or an L-shaped metal fitting is attached. Was used to bind locally.

On the other hand, with the recent development and popularization of electric devices, 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]

[Problems to be solved by the device]

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

Further, in the case where the L-shaped metal fitting is used, stress concentrates on this metal fitting, which is disadvantageous in strength and is not well-formed.

In the case where the member is provided with the wiring groove 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 reduced. Also, because the cover is conspicuous, the aesthetics are also spoiled.

[0007]

Means for Solving the Problems The present invention is intended to solve the above-mentioned problems in the conventional ones, and is characterized in that almost the entire length of the joint portion of the two members to be joined. It has two side pieces each having a length extending over the same angle as that of the connecting portion of the two members, and a slot formed between the side ends of both side pieces is detachable. That is, it was closed with a cover.

[0008]

[Action]

 The connecting metal fitting extends over the two members to be joined and holds them at a required angle.

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

[0010]

【Example】

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

The upper edges of the side plates (2) and (2) having the same depth as that of the top plate (1) are fixed to both ends of the top plate (1) by a known appropriate means (not shown). Slightly forward of the rear edges of the top plate (1) and the side plates (2) and (2), between the lower surface of the top plate (1) and the facing surface of the side plates (2) and (2), the curtain plate (3 ) Is provided.

[0012] A suitable number of receiving holes (4) (5) are formed in the side end surface of the curtain plate (3) and the contact portion of the top plate (1) and the side plate (2) with the curtain plate (3). A stopper shaft (6) is fitted over the set. The stopper shaft (6) is adhered to each of the receiving holes (4) and (5) as required. 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 includes the curtain plate (3) and the other side. It is provided so as to straddle the members.

The connecting fitting (7) is a tubular member having an isosceles right-angled cross section and having the same length as the contact end surface of the curtain plate (3) with respect to the mating member, and is made of metal. (8) A longitudinal slot (10) is provided at the center of the oblique piece (9) connecting (8).

The connecting metal fitting (7) has one of the orthogonal side pieces (8) and (8) on the side end of the curtain plate (3) and the other on the top plate (1) or side plate (2). The set screws (12) that are brought into contact with each other and inserted into the holes (11) provided in each side piece (8) are screwed into the mating member with which the side piece (8) comes into contact, so that the 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 attaching the connecting metal fitting (7) as described above, pass the cord (15) or the like through the inside, and then fit the cover (13) into the groove hole (10), The locking pieces (14) (14) are engaged with the edges of the slot (10).

FIG. 4 is a perspective view of a table in which a side plate is fixed to a leg rod using a different example of the connecting fitting of the present invention, and FIG. 5 is an enlarged cross-sectional view of the fixing portion.

[0018] At the four corners of the top plate (21), tubular metal rods (22) having an outward triangle in cross section are fixed by any known suitable means.

Side plates (23) are provided between the front and rear leg rods (22) and (22) on both sides of the top plate (21).

The front and rear end faces of the side plate (23) are orthogonal to the plate face, and the cross section of the leg rod (22) is an outward triangle. Therefore, in order to connect both of them, the connecting metal fitting (24 ) Is used.

The connecting metal fitting (24) has a length substantially equal to that of the side plate (23) and can be brought into contact with the end face of the side plate (23), and from one end of the base piece (25), the inner piece of the leg rod (22). It has a narrow-angle L-shaped cross section composed of an inclined piece (27) inclined at the same angle as (26). A slot (28) is formed in the longitudinal direction between the free ends of the base piece (25) and the oblique piece (27).

The set screw (30), which is inserted into the hole (29) formed in the base piece (25) of the connecting fitting (24), is screwed into the end face of the side plate (23), and the connecting fitting (24) is slanted. Fit the setscrews (32) through the holes (31) formed in the piece (27) into the space between the opposing engaging ridges (33) (33) formed on the back side of the diagonal piece (27). The side plate (23) and the leg rod (22) are coupled to each other by being screwed into the square plate nut (34) so that the relative height can be adjusted.

After inserting the cord (35) along the lower surface of the front edge of the top plate (21) into the connecting fitting (24), insert the cover (35) into the opening of the connecting fitting (24). Used by fitting and locking appropriately.

The leg rod (22) may be a wooden triangular rod.

[0025]

[Effect of the device]

 (a) The two members are joined together by the connecting fitting over the entire length of the joining surface, so that the joining strength is large.

(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 groove hole in the connecting fitting is closed by the detachable cover, the inside code, the mounting set screw, and the like cannot be seen from the outside, and the appearance is good.
