Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a joining structure for a furniture top plate in which two top plate members are joined in a planar direction.

(Prior art) Conventionally, when the top plate for furniture such as kitchen furniture, counters, tables, etc. is long or has an orthogonal planar shape such as an L-shape or a shape, It is common practice to join two upper plate members in a planar direction to integrate them.

To join these two upper plate members, the joint metal fittings are fixed to the back side of the upper plate member by means such as screws or welding, and the fixed joint metal fittings are tightened together with bolts and nuts, so that the joint metal fittings are aligned horizontally and vertically. By moving the two upper plate members relative to each other in the vertical direction, the two upper plate members to be joined are leveled and the gap between the joined members is eliminated.

(Problem to be solved by the invention) In the case of conventional joining fittings, the first and second joining fittings are attached to the upper plate member while aligning the vertical and horizontal holes through which the tightening bolts are inserted. Since it needs to be firmly fixed, it has the disadvantage that it is troublesome and time-consuming to install the joining metal fittings. In particular, when the upper plate member is a top plate that closes the upper surface of the cabinet, the joining metal fittings must be fixed from below, which is extremely troublesome.

(Means for solving the problems) This invention solves the above-mentioned problems seen in the conventional joint structure, and it
A vertical piece 3b is attached to a horizontal fixed piece 3a fixed to the back side of the
and the bolt thread insert 3c are integrally continuous in the shape of the first
A second joining fitting 4, a vertical bolt 9, and a horizontal bolt, which has a continuous cross-section of the joining fitting, the upper horizontal piece 4a, the vertical piece 4b, and the lower horizontal piece 4c fixed to the back surface of the other upper plate member 2. It consists of 10,
Vertical pieces 3b, 4b of the first and second joint fittings 3, 4
A bolt insertion hole 11 and a long hole 7 extending vertically are formed in the bolt insertion hole 11, and a vertical bolt insertion groove 8 that opens laterally is formed in the lower horizontal piece 4c of the second joint fitting 4. Screw the screw hole 6 into the bolt screw insert 3c of the first joint 3, insert the horizontal bolt 10 into the bolt insertion hole 11 and the elongated hole 7, tighten it with the nut 12, and insert the vertical bolt 9. It is characterized in that it is inserted into the groove 8 and screwed into the screw hole 6 to join the first and second joining fittings 3 and 4.

(Function) A bolt insertion groove that opens laterally is formed in the horizontal piece of the second joint metal fitting, and a vertical bolt is inserted into the insertion groove from the side and screwed into the first joint metal fitting. Since the first and second joining fittings are relatively accessible in the vertical direction, a vertical bolt is screwed into the first joining fitting in advance, and this vertical bolt is inserted into the insertion groove of the second joining fitting. Accordingly, alignment for insertion of the first and second vertical bolts and horizontal bolts can be achieved.

(Effect of the invention) By inserting the vertical bolt screwed into the first joint metal fitting into the insertion groove of the second joint metal fitting, the insertion groove for vertical bolt insertion and the screw hole can be aligned. Of course, it is also possible to align the elongated hole for inserting the horizontal bolt and the bolt insertion hole, and it is also possible to align the bolt insertion hole with the long hole for inserting the horizontal bolt. Positioning can be achieved extremely easily, and the work of fixing the joining fittings is easy, which has the effect of improving work efficiency.

(Embodiment) A preferred embodiment of this invention will be described below with reference to the drawings. In the figure, numerals 1 and 2 are upper plate members constituting the upper plates of kitchen furniture, counters, tables, etc., and are made of wood or metal plates such as stainless steel plates.

By abutting and joining the two upper plate members 1 and 2 in the planar direction at their opposing side end surfaces, a long upper plate having a desired length can be constructed, or the end edges to be butted The upper plate can be configured to have an L-shape or a perpendicular planar shape such as an L-shape or the like with the oblique side at 45° with respect to the plane.

A pair of joining metal fittings 3, 4 is fixed to the back surface of each upper plate member 1, 2 adjacent to the joining end surface with screws 5.

The first joining fitting 3 has a horizontal fixed piece 3a fixed to the back surface of the first upper plate member 1, and a vertical piece 3b hanging down from the tip of the fixed piece 3a, and has a horizontal piece 3b attached to the lower end of the vertical piece 3b. A bolt thread insert 3c is integrally extended. The horizontal screw insert 3c extends downward from the second upper plate member 2, and a screw hole 6 is bored in the center of the screw insert 3c.

The second joint metal fitting 4 has a cross-sectional shape, the upper horizontal piece 4a of the joint metal fitting 4 is a fixed piece fixed to the back surface of the second upper plate member 2, and the vertical piece 4b has a vertical piece extending in the vertical direction. A long hole 7 is drilled. An insertion groove 8 that opens laterally is formed in the lower horizontal piece 4c, and a vertical bolt 9 can be inserted from the side and inserted into the lower horizontal piece 4c. The insertion groove 8 is the vertical bolt 9
The vertical bolt 9 can be easily inserted and removed because it is a blank hole.

The bolt insertion hole 11 formed in the vertical piece 3b of the first joint 3 and the vertical piece 4b of the second joint 4
Loosely insert the horizontal bolt 10 into the elongated hole 7 formed in the
Tighten and connect with nuts 12. horizontal bolt 10
is movable in the vertical direction within the range of the elongated hole 7 relative to the second joining fitting 4.

When joining the upper plates, first, the first and second joining fittings 3 and 4 are fixed in advance to predetermined positions on the back surfaces of the upper plate members 1 and 2 with screws 5. Then, insert the vertical bolt 9 into the insertion groove 8 from the side, screw the lower part into the screw hole 6 of the first joint 3, and connect the first and second joints 3 and 4 with the vertical bolt 9. do. Further, a horizontal bolt 10 is inserted into the bolt insertion hole 11 and the elongated hole 7, and is tightened with a nut 12 to connect the first and second joining fittings 3 and 4 with the horizontal bolt 10.

After fixing the first and second fittings 3 and 4, screw the vertical bolt 9 in the vertical direction with a screwdriver 13,
The first and second joining fittings 3 and 4 are moved relative to each other in the vertical direction. By the relative movement of the joining fittings 3 and 4 in the vertical direction, the upper plate members 1 and 2 are relatively moved up and down, and are positioned on the same horizontal plane with respect to the planar direction of both members 1 and 2. Next, the horizontal bolt 10 is screwed to move the joining fittings 3 and 4 relatively in the horizontal direction. By the relative movement of the joining fittings 3 and 4 in the horizontal direction, the upper plate members 1 and 2 are brought relatively close to each other, the gap between the two members disappears, and the abutting surfaces are brought into close contact. In this way, the upper plate members 1 and 2 are leveled and the gaps are eliminated in the vertical and horizontal directions, and a reliable joint is achieved.
