Description

[Detailed Description of the Invention] Industrial Application Field The present application relates to a device for connecting a desk body and a bookshelf in a study desk.

BACKGROUND ART Conventionally, in a study desk, when a bookshelf is connected and fixed on the top plate of the desk body, an upwardly extending attachment is attached to the top end of the U-shaped intervention part that intervenes on the side edge of the top plate. using a connecting fitting formed by providing a section and drilling a mounting hole in the mounting section, and screwing a tightening screw having an abutting section at the upper end and a knob at the lower end into the lower intervention piece. When connecting and fixing the desk body and the bookshelf, insert the side edge of the top plate into the intervention part, and in that state screw the mounting screw into the nut embedded in the side plate of the bookshelf through the mounting hole. Then, turn the tightening screw to tighten the top plate between the contact part and the intervention part, or bury a nut in the bottom surface of the side plate of the bookshelf and install a mounting hole in the position facing the nut in the top plate. A method is adopted in which a screw shaft is inserted into the mounting hole from below the top plate and screwed onto the nut.

Problems to be Solved by the Invention However, according to the above-mentioned former connection method, since the connecting fittings are tightened and fixed to the bottom surface of the top plate, it is difficult to reduce the protrusion width of the top plate that protrudes laterally from the side wall surface of the desk. Like a desk that requires a large space, so the sleeve width of the desk is widened relative to the width of the top board.
It is difficult to use it on desks with a small protruding top plate.
Moreover, according to the latter connection method, when the bookshelf was removed and the desk was used alone, the mounting holes were exposed in several places, which seriously spoiled the appearance.

Means for Solving the Problem Therefore, the present application solves the above-mentioned defects of the conventional product, and its gist is that the lower edge is provided with an inward locking pawl, and the upper edge is provided with an abutting portion. A connecting fitting formed integrally with a mounting part bent outward and provided with a branch having a screw hole through a bent step, and an insertion hole extending in the thickness direction at least in the back and center part. a cover member integrally having an upper part, and the cover member is fixed to a bookshelf side plate so that the lower surface thereof is separated from the top plate surface,
Also, the locking claw of the connecting fitting is opposed to the lower surface of the top plate, the supporting piece is opposed to the upper part of the cover member, and the tightening screw is screwed into the screw hole through the insertion hole. The device is characterized in that a locking claw is locked to the bottom surface of the top plate by a tightening operation.

Embodiment and operation To explain the embodiment of the present application in detail with reference to the drawings, 1 is a long plate piece bent at an intermediate position so that the lower part engages with the lower surface of the side edge of the top plate a of desk A. A vertical abutment part 3 with an inward locking claw 2 on the lower edge, a horizontal bent step part 4 in the middle part, and a screw hole bent outward in the upper part. A connecting fitting integrally formed with a vertical mounting part 8 having a branch piece 6 having a diameter of 5 on the upper edge and an opening 7 in the center, and 9 is preferably a synthetic material into which the mounting part 8 is inserted. A cover member made of resin, which includes a vertical back part 11 having a through hole 10 in the center, left and right side parts 12 and 13, and a front face with a lower part slightly shorter than the back part 11 and a long hole 14 in the center. 15, and a thick upper part 17 that communicates with an insertion hole 16 that penetrates in the thickness direction at the center and has a large diameter at the upper part. Reference numeral 18 denotes a mounting screw which is screwed into the nut 19 which is horizontally buried in the side plate b of the bookshelf B through the opening 7 and the through hole 10, and 20 which is screwed into the screw hole 5 through the insertion hole 16. This is the matching mounting screw.

Therefore, in use, the bent step part 4 is placed on the top surface of the top plate a with the mounting part 8 inserted into the cover member 9, and the inner surface of the contact part 3 is placed on the side surface of the top plate a. At the same time, the locking claw 2 is opposed to the lower surface of the locking claw 2. In this state, the mounting screw 18 is inserted through the opening 7, the elongated hole 14, and the through hole 10, and the nut 1 is screwed into place.
9, the back of the cover member 9 and the mounting portion 8 of the connecting fitting 1 are temporarily fixed to the side plate of the bookshelf B. Next, the tightening screw 20 is inserted into the insertion hole 16 and screwed into the screw hole 5, and when the tightening screw 20 is tightened, an upward tightening force is applied to the connecting fitting 1, and a downward tightening force is applied to the side plate of the bookshelf B. A tightening force is applied, whereby the locking pawl 2 is locked to the lower surface of the top plate a, and the bookshelf B is pressed onto the top plate a by the screw engagement between the mounting screw 18 and the nut 19. Ru. Next, the desk A and the bookshelf B are connected by tightening the mounting screws 18.

In addition, in the above, it goes without saying that only the cover member may be fixed to the side surface of the bookshelf.

Effects of the invention As described above, according to the present application, by tightening the tightening screw, the bookshelf is pressed against the desk top plate by the relative tightening force acting on the connecting fittings and the bookshelf side plate, and Since the locking claws lock onto the bottom surface of the top plate, the bookshelf can be securely attached to the desk even for desks with a small protruding top plate, such as a configuration in which the sleeves of the desk are expanded close to the width of the top plate. Can be firmly connected,
In addition, there are no pressure marks on the top surface of the top plate for connecting fittings and cover members, and there are no mounting holes.
When you separate the desk and bookshelf and use the desk alone,
There is no risk of spoiling the appearance, and the desk and bookshelf can be easily connected and removed.
