Description

[Detailed description of the invention] (a) Industrial application field The present invention mainly relates to a connection mechanism between a wooden top plate and legs of a desk on which a personal computer or other electronic equipment is placed.

(B) Conventional technology As mentioned above, a desk on which electronic equipment is placed has a structure in which the rear edge of the top plate is supported by a column, the column is supported by a vertically long leg frame, and the side surface is approximately U-shaped. In addition, it is usually made entirely of a metal plate.

(c) Problems that the invention aims to solve As mentioned above, it goes without saying that all-metal desks have extremely good durability and storage stability, but they are too mechanical and have a poor feel. A good wooden tabletop would be desirable, but since we will be placing a fairly heavy electronic device on it, and the tabletop will only be supported by the pillars near the rear edge, the tabletop and legs will not fit properly. Unless a sufficiently rigid connection is provided between the
There was a problem that it was inferior in robustness and durability.

(d) Means for solving the problem Therefore, in the present invention, a rectangular recess is bored on the back side of the wooden top plate, and the mutually opposing inner walls of the recess are made of cross-sectional angle members. A pair of mounting brackets are fixed, and a leg connecting plate with a cross-sectional shape and a locking protrusion perforated at one end that overlaps with these mounting brackets is coupled and fixed to the bracket, and a pair of legs with a leg frame planted thereon are fixed. The above-mentioned locking protrusion is fitted to the support, thereby making the connection and fixation of the wooden top plate to the metal support solid and easy to assemble.Based on the embodiment shown in the drawings below. The gist of the present invention will be explained.

(E) Embodiment Fig. 1 is a perspective view showing an embodiment of a desk based on the coupling mechanism of the present invention, Fig. 2 is an enlarged exploded perspective view of the coupling mechanism of the same desk, and Fig. 3 is a view similar to Fig. 1A- It is an enlarged sectional view of the A line part.

In the drawing, 1 is a top plate made of wood, and all other parts are made of metal. 2 is the wooden top plate 1 mentioned above.
A rectangular recess is bored at a position close to both ends of the rear edge of the back surface of the top plate 1, and a protrusion 2a is provided on the inner wall on the side edge 1a side of the top plate 1, and a nut 5a of the mounting brackets 3, 3, which will be described later, is received therein. In addition, as shown in the enlarged sectional view of FIG. 3, a groove 2c into which the upper piece 3a of the mounting bracket 3 is press-fitted is provided.

The above-mentioned mounting bracket 3 is made of a cross-sectional angle member, and a nut 5a into which a bolt 5 is screwed is welded, and a plurality of through holes 3c for receiving screws 6 are bored in the lower piece 3b.

4 is a leg connecting plate, which is formed into a cross-sectional shape and has a side edge 4.
a, 4a are bent, locking protrusions 4b are respectively protruded from the ends of the side edges 4a, and a recess 4c is provided to face and fit into the protrusion 2a of the square recess 2. Through-holes 4d, 4 through which the
d... is drilled.

Reference numerals 7 and 7 indicate leg supports arranged in parallel, each of which is made of a rectangular tubular member, the lower end 7a of which is fixed close to the front end of the leg frame 8, and the upper end 7b of which is fixed with a horizontal frame 9 that directly supports the back surface of the top plate 1. It has been done. Numeral 10 is a screw that passes through the through hole 9a of the horizontal frame 9 and is screwed into the screw hole 1b of the top plate 1. Numeral 11 is a screw that is screwed into the screw holes 8a, 8a at both ends of the leg frame 8 to adjust the height. 12 is a cover.

(F) Function In the present invention having the above-described configuration, the mounting brackets 3, 3, to which the nuts 5a are welded in advance, are fixed to the opposing inner walls of the rectangular recessed portion 2 by pressure contact, respectively, via the screws 6. The upper piece 3a is press-fitted into the groove 2c to further strengthen the connection between the wooden top plate 1 and the mounting bracket 3. Next, the side edge 4a of the leg connecting plate 4,
4a are superimposed on the mounting fittings 3, 3, respectively, and the recesses 4c are fitted into the projections 2a on the side of the top plate 1, and the bolts 5 are passed through the through holes 4d and screwed into the respective nuts 5a and tightened.

On the other hand, a pair of rectangular cylindrical leg supports 7, 7 are planted and fixed near one end of the leg frame 8, and a horizontal frame 9 that abuts and supports the top plate 1 is fixed. Fit the locking protrusions 4b, 4b of the leg connecting plate 4 on the top plate 1 side to the upper ends of the leg supports 7, 7, and screw the horizontal frame 9 into the screw hole 1b through the through hole 9a with the screw 10. This is something that must be tightened.

Therefore, by removing the screws 10, the top plate 1 and the leg portions can be easily separated.

In addition, the cross-sectional mounting brackets 3, 3 are firmly fixed to the opposing inner walls of the rectangular recessed part 2, and the leg connecting plates 4, 4 are bolted to these, so that the top plate 1 and the leg connecting plate 4 can be connected to each other. The bond becomes even stronger and more solid.

(g) Effect of the invention As mentioned above, the rectangular recess 2 is bored, the cross-sectional mounting brackets 3, 3 are fixed therein, and the leg connecting plate 4 is bolted to the mounting brackets 3, 3. Therefore, the connection between the wooden top plate 1 and the leg connecting plate 4 is extremely strong, and can sufficiently withstand the deviation of the load due to the leg supports 7, 7 being biased toward the rear edge, allowing long-term use. The wooden top plate provides a solid feel and calm appearance, and has excellent features that can provide a comfortable environment for the user.As mentioned above, it is extremely easy to attach and remove the legs and the top plate. Yes, the practical benefits are quite significant.
