Description

[0001] The present invention relates to a table having an integral lower fastening structure,

The present invention relates to a table having an integral lower fastening structure capable of combining a frame and a leg with a single bolt and nut, and not only can the efficiency of work be improved by a simple fastening method, To a table having an integral lower fastening structure which is advantageous for productivity and cost reduction.

Typically, furniture such as a table is supported by the lower legs and the legs are again supported by the frame, which frames are configured to be interconnected by a connecting device.

Particularly, in order to connect the lower leg to the frame, it is necessary to weld the frame and the respective legs or weld the two legs by installing the intermediate supports in a state of spacing the two legs, Are inserted.

However, such a conventional lower fastening structure is troublesome and inconvenient, and also causes a problem of inefficiency of work and lowering of productivity.

The applicant of the present invention has filed a table as shown in Fig. 1 and has been registered as a registered utility model No. 437233 of the Republic of Korea in order to overcome such shortcomings. The registra- tion utility model includes a bushing 4 in which a corner bracket 6 is welded to a frame 2 and to which a nut fastened to a bolt 5 passing through the corner bracket 6 is inserted, Is inserted.

However, since the corner bracket 6 is welded to the frame 2, there is a disadvantage that the entire frame must be moved or stored together, and it is also difficult to manufacture the parts by modularization.

The object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to provide a method and apparatus for connecting and fixing a frame and a lower leg simultaneously by a single bolt fastening operation, And a table having an integral lower fastening structure.

In order to achieve the above object, according to the present invention, there is provided a table having an integral lower fastening structure, comprising: an upper plate; a frame positioned below the upper plate; and a leg extending downwardly from the frame, A bracket including a bushing to be inserted, an insertion groove formed in an inner surface of the frame, and an insertion piece inserted into the insertion groove.

Further, through holes for bolt-nut coupling are formed at corresponding positions of the legs, the bushings and the brackets, and the brackets are formed to have a triangular shape or a " a " shape.

As described above, the table having the integral type lower fastening structure according to the present invention can easily connect and fix the frame and the lower leg at the same time by only one bolt fastening operation, and is convenient for carrying and storing, And an advantageous effect for productivity and cost reduction is obtained.

The above and other objects and novel features of the present invention will become more apparent from the description of the present specification and the accompanying drawings.

Hereinafter, configurations of the present invention will be described with reference to the drawings.

As shown in Figs. 2 to 4, the table having the integral lower fastening structure according to one embodiment of the present invention includes an upper plate 1, a frame 21 positioned below the upper plate 1, The table comprises a leg (31) installed below the frame (21), the table comprising a bushing (51) inserted into the leg (31) of the table, the frame (21) And a bracket 53 having an insertion groove 71 and an insertion piece 71 which is inserted into the insertion groove 73.

The insertion pieces 71 are inserted into the insertion grooves 73 so that the two adjacent frames 21 are fixed by the single bracket 53 so as not to be separated. It is a matter of course that the shape of the insertion piece 71 and the insertion groove 73 can be variously modified in order to increase the rigidity of the coupling.

It is preferable that the bracket 53 has a substantially triangular shape when viewed from above, but it is also possible to have a bracket shape like a conventional bracket.

Through holes 61, 63 and 65 for coupling bolts 55 and nuts 57 are formed at corresponding positions of the legs 31, the bushings 51 and the brackets 53, and the through holes 61 The bushing 51, the frame 21 and the bracket 53 are engaged / fastened at one time by the bolts 55 and the nuts 57 which are fastened to the brackets 63,

The nut 57 may be fixed to a corresponding hexagonal groove on the inside of the bushing 51 so as not to be separated from the hexagonal groove for convenience of assembly. The bolts 55 are preferably hexagonal wrench bolts or butterfly bolts.

The assembling process of the table having the one-piece lower fastening structure according to the present invention is as follows.

The engaging of the frame 21 and the bracket 53 is provided by inserting the insertion piece 71 of the bracket 53 into the insertion groove 73 of the frame 21 adjacent to the frame 21, The bushing 51 is inserted into the leg 31 so that the bracket through hole 65 is aligned with the leg through hole 63 and the bushing through hole 61 is located at the position corresponding to the aligned through holes The assembly of the lower fastening structure is completed by fastening the bolts 55 and the nuts 57 passing through the through holes 61,

When the fastening structure assembly of the lower part of the upper plate 1 is completed in this way, it is combined with the upper plate 1 to complete the table. Since a number of methods for joining with the top plate 1 are known, a detailed description thereof will be omitted.

Although the embodiments of the present invention have been described in detail with reference to the above embodiments, it is to be understood that the present invention is not limited to the above embodiments and that various changes and modifications may be made without departing from the spirit and scope of the invention.

The present invention is applied to a table having an integral lower fastening structure.
