Description

Metal plate material {a steel panel}

The present invention relates to a metal plate that is bent on all sides of the metal plate to be used as a top plate, shelf, door, etc. of the various tables. It relates to a design to be made easily.

In general, the metal plate material has a form in which the metal plate having a thickness of about 1 ton is continuously bent at right angles at a right angle. The metal plate material is robust and is actively used as a top plate, a shelf, a door, etc. of various tables.

Since the above-described metal sheet material is manufactured by bending the metal plate at a right angle, the corner portions are formed very sharply and thus may be injured by users, so it is important to process the corners to form a smooth curved surface.

As the method of processing the corners of the metal plate, the method of mainly welding the edges and grinding them with a grinder to process the edges into a smooth curved surface is not only very difficult but also the work efficiency is remarkable as all the work is done by hand. Problems such as deterioration occurred.

In addition, when grinding the edges with a grinder by hand, it is difficult to process the edges uniformly to form the same shape, so that the appearance of the metal sheet may not be beautifully maintained, and skilled to form the same shape as the edges. Because of the need for workers, a lot of labor costs have been discontinued.

The present invention was devised in view of the above-mentioned problems, and an object thereof is to provide a metal plate material which can be made very easily by treating a corner of the metal plate material by combining a synthetic resin supporter with a corner portion of the metal plate material.

Features of the present invention for achieving the above object, the four sides of the metal plate is continuously bent at right angles to form a side plate 12 on all sides of the upper plate 11, the guide plate 13 in the lower portion of the side plate 12 In the metal plate member 10 is bent inwardly, the coupling groove in which a portion of the upper plate 11, both side plates 12, both of the guide plate 13 is cut in the corner portion of the metal plate member (10) 20 is formed, and the support groove 30 having a curved edge is inserted and fixed in the coupling groove 20, and the elastic pieces 31 are formed on both inner surfaces perpendicular to each other at the inside of the support 30, respectively. It can be achieved by a metal plate characterized in that is fixed to each of the upper surface of the guide plate 13 is fixed.

Hereinafter, described in detail by the accompanying drawings a preferred embodiment for achieving the above object is as follows.

As shown in FIGS. 1 to 4, the metal plate 10 according to the present invention is continuously bent at right angles to four sides of the flat metal plate, and the side plates 12 are formed at four sides of the upper plate 11, respectively. The lower part of the board 12 has the structure in which the guide board 13 was bent inward.

Of course, the metal plate 10 having the above-described configuration is a known art idea. However, the most important feature in the present invention is that the support 30 made of synthetic resin is coupled to the coupling groove 20 formed at the corner portion of the metal plate 10 so as to smoothly form the edge.

That is, a coupling groove 20 in which a part of the upper plate 11, a part of both side plates 12, and a part of both guide plates 13 is formed at the corner portion of the metal plate 10.

The support groove 30 made of synthetic resin is inserted into the coupling groove 20 so as to smoothly form the edge of the metal plate 10.

The edge portion of the support 30 is made of a smooth curved surface, the elastic pieces 31 are formed on both inner surfaces perpendicular to each other in the inner side of the support 30 are formed on the upper surface of both guide plates 13 Each hangs and is fixed.

That is, as shown in FIG. 2A, when the synthetic resin supporter 30 is pushed up from the bottom of the coupling groove 20 formed at the edge of the metal plate 10, the inner side of the supporter 30 is moved outwardly. The protruding elastic piece 31 contacts the both guide plates 13 of the metal plate 10 and is pressed inward, and the support 30 is inserted into the coupling groove 20, and the support 30 is When fully inserted into the coupling groove 20, as shown in FIGS. 2b to 4, the elastic pieces 31 are positioned on the upper surface through the guide plate 13 so that the pressed elastic pieces 31 are elastically restored to the outside. At the same time as being protruded while pressing both sides of the guide plate 13, the support 30 is supported between the two guide plate 13 is firmly fixed to the coupling groove (20).

Therefore, the support 30 can be formed into a smooth curved surface by a simple operation to be fitted to the coupling groove 20, and because it can be used very safely, the working time can be shortened to maximize the efficiency of the work. As well as the overall shape is to form the same shape to be able to keep the appearance beautiful as to enhance the external competitiveness of the metal plate 10 as possible.

Steps 32 corresponding to the thickness of the metal plate 10 are formed on the upper surface and both outer surfaces except for the corner portions of the support 30, and the step 32 is provided to cut the portion of the coupling groove 20. Along the line contact and the outside of the step 32 is located outside the coupling groove 20 to form a soft edge and the inside is in close contact with the interior of the coupling groove (20).

Therefore, since the portion forming the corners of the supporter 30 forms the same surface as the metal plate member, the edge of the metal plate member 10 can be formed more beautifully and can be actively utilized as a top plate or a shelf of various tables.

As shown in FIG. 5, the support 30 is coupled to the coupling groove 20 formed at the edge of the metal plate 10 used as a door such as an item storage box with a hinge 40 mounted on one side thereof. May be used.

Meanwhile, as shown in FIG. 6, the side plate 12 formed on one side of the upper plate 11 of the metal plate 10 is continuously bent at a right angle so that the guide plate 13 is formed at the bottom thereof, and the other side surfaces in three directions. The plates 12a are semicircularly bent to form two semicircular coupling grooves 20a at two corners at which the side plate 12 and the semicircular side plate 12a meet each other to form a semicircular coupling groove 20a. The semicircular support 30a having the elastic piece 31a may be coupled to the semicircular engaging groove 20a so that the elastic piece 31a is caught inside the right angled side plate 12.

The present invention as the coupling grooves 20 formed at two corners of the semi-circular side plate (12a) to meet each other is coupled to the supporters 30 are formed with two elastic pieces 31 on both inner sides of the coupling grooves (20) Metal plate material 10 by using can be used to form more variously.

In the above described and illustrated with respect to the preferred embodiment of the present invention, the present invention is not limited to the above-described embodiment, it is common in the field to which the present invention belongs without departing from the spirit of the present invention claimed in the claims. Various modifications can be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.

The present invention as described above, the edge can be formed into a smooth curved surface by a simple operation to fit the support 30 made of synthetic resin into the coupling groove 20 formed on all sides of the metal plate 10 and As it is very safe to use, the processing time of the corner is shortened to maximize the efficiency of the work as well as the overall shape of the corner is the same shape, so that the appearance can be beautifully maintained. There is an advantage, such as to provide a high-quality metal sheet material 10 that can be actively utilized as a door for.
