The present invention relates to a drawer assembly structure of iron furniture, and more specifically, a drawer for a steel desk or a file box is made in a subcontracting factory and delivered to a finished product factory. By supplying a large amount of goods at once, the logistics cost can be considerably reduced. In the finished product factory, it is easy to bend and assemble by hand without using a bending machine, so the drawer assembly structure of steel furniture can be improved significantly. It is to provide.

Generally, the drawer of iron furniture is made of iron plate by bending the main body into 'c' shape, the front surface of steel or wood is assembled together with the back plate, and the back plate made of iron plate is welded on the back. The finished product factories that make these iron furnitures are now using the ones produced by subcontractors instead of making drawers by themselves.

By the way, the drawer body for iron furniture made in the existing subcontracting factory is to bend both sides of the plate body of considerable thickness as it is standing, so a considerable force is required, so that the operator can not be easily bent by hand, using a dedicated bending device for each one It had to be bent, which causes a problem that takes a long time.

That is, in the process of making a drawer in the existing subcontracting factory, first, the iron plate is cut to a predetermined size, and then bending, perforation, and flange formation of the necessary parts are made by a bending device and a press machine to make a plate for a drawer, and then bending the plate Placed in the device, both parts were bent at right angles to stand so that both side walls 12 and bottom 11 of the drawer body 10 were as shown in FIG.

However, bending both sidewalls 12 of the drawer body 10 with a bending machine in this way takes a very long time, and the back plate 16 for assembling the front plate 15 of the drawer body 10. To attach the rear plate 17 to the drawer body 10 using a complicated welding means, and in particular to make a separate bracket 14 for joining the slide rail 20 to weld to the side wall 12 There is a problem that the productivity is significantly reduced because it has to go through the process.

In addition, when the subcontractor supplies the drawer to the finished product factory, the drawer is transported in a box-shaped state as described above, and the drawer made of the box-type is bulky so that a large amount can be loaded in a loading box of a truck. Therefore, as several units are transported in a single unit, logistics costs are considerably high, which is a major factor in the cost increase.

Therefore, the present invention is designed to solve the conventional problems as described above, the purpose of the present invention is to deliver a large amount at a time when delivering the drawer body to the finished product factory in the subcontracting factory to reduce the logistics cost, In the finished product factory, the plate-shaped drawer body supplied can be easily assembled by a worker without using a bending device, thereby achieving convenience and productivity.

Another object of the present invention is to form a plate body by rolling and pressing the drawer is formed to be integrally provided with a slide rail mounting bracket on both outer walls to improve productivity by not having to go through the process of making a separate bracket as in the prior art In addition, the back plate and the back plate for assembling the front plate to provide a structure that can be easily assembled to the body.

Hereinafter, described in detail by the accompanying drawings, the technical configuration and operation that can effectively achieve the object of the present invention as a preferred embodiment as follows.

That is, FIG. 2 is a perspective view of a drawer plate body in which the present invention is implemented, and FIG. 3 is a perspective view showing a state in which both sidewalls are bent and the back plate and the back plate are assembled in the plate body of FIG. 2. When pressing the iron plate to a predetermined size, a plurality of cutouts 130 are formed in a line along a portion for distinguishing the bottom portion 110 and both wall portions 120, and both wall portions 120 are formed by hand. It is characterized in that the drawer 100 is formed to be easily bent.

Then, both ends of the wall 120 are bent in the 'S' shape to form a partition fitting hole 123 (the upper end when the wall 120 is formed) so that the slide rails 200 can be coupled. The bracket part 140 and the support part 142 in which the hooks 141 are punched on both sides thereof are integrally extended by a predetermined width, and then the bracket part 140 is outside so that the support part 142 is in contact with the outer surface of the wall part 120. It is characterized in that it is bent and formed integrally.

In addition, the front and rear sides of the bottom 110 and both wall parts 120 are formed by bending the elastic engaging pieces 111 and 121 toward the inner surface, respectively, to fix the front plate 150 and the back plate 160. ) And the flanges 161 and 171 of the rear plate 170 are fitted to the engaging pieces 111 and 121, and a plurality of insertion holes 122 are provided in the rear engaging pieces 121 of the wall part 120. ) And both sides of the flange 171 of the rear plate 170 to be fitted thereto, and the back plate 170 is assembled by caulking the protrusions 172 fitted into the insertion hole 122. .

In the drawing, reference numeral 113 is a partition fitting hole formed in the bottom part 110, but in the drawing was perforated integrally with the cutout hole 130, but may also be perforated in a state spaced apart from each other according to product specifications, (151) ) Is a plurality of bolt holes formed in the back plate 160 to fix the front plate 150, 210 is the side of the slide rail 200 to be hooked to the hook 141 of the bracket portion 140 It is a ring formed by punching.

When the present invention formed as described above is delivered to the finished product factory from the subcontractor, the drawer body 100 in the form of a plate and the back plate 160 and the back plate 170 are assembled to the van as it is separated from each other in the state What is to be sent by stacking, the drawer 100 of the present invention is stacked in the form of a thin plate, so the volume is smaller, so that more volume can be sent at a time can significantly reduce the logistics cost of transportation.

In addition, the worker of the finished product factory that has received the drawer 100, the back plate 160, and the back plate 170, lifts the wall part 120 by holding the bottom 110 of the drawer 100. If only the partition portion of the wall portion 120 and the bottom portion 110 is easily bent by the cutting hole 130, the wall portion 120 is erected, in this state the back plate 160 and the back plate 170 When pushed against each surface, the flanges 161 and 171 are fitted to the engaging fastening pieces 111 and 121 to be caught.

In such a state, the back plate 160 of the present invention is firmly fastened by assembling the front plate 150 using the bolt hole 151 as in the usual drawer, and the back plate 170 has a flange 171. When fitted to the engaging piece 121, the caulking formed projection 172 is caught in the insertion hole 122 of the engaging piece 121, so that the fastening force assembled as a drawer without welding the back plate as in the prior art is very solid.

In addition, the present invention is because the bracket 140 for the rail 200 is integrally bent on both sidewall outer surfaces when the drawer body 100 is formed by pressing and bending processes by cutting the iron plate member to a predetermined size, as described above. The brackets 140 for attaching the slide rails 200 are integrally provided on the outer surfaces of both sidewalls simply by assembling both sidewall parts from the bottom part 110 with the drawers.

Therefore, there is an advantage of not having to go through a complicated work process such as welding a separate bracket by making a separate bracket as in the prior art can improve the productivity.

In addition, if the rail bracket is located at the bottom of both side walls as in the conventional drawer, the weight of the drawer is transferred to the rail as it is placed on the rail while the center of gravity of the drawer, which is considerably heavy by the storage items, is underneath. While a large amount of force is required to move the drawer, when the bracket 140 for the slide rail 200 is positioned above both of the wall portions 120 of the drawer as in the present invention, the drawer heavy by the storage items is placed on the rail. When suspended, the center of gravity of the drawer is lowered down, allowing the drawer to open and close smoothly.

In this way, when the drawer is delivered from the subcontracting factory to the finished product factory, the drawer body, the back plate, and the back plate are delivered separately from each other, so that a large amount can be transported at once, resulting in a large logistic cost reduction effect. Without the need for a separate machine, the plate-shaped drawer can be easily bent and assembled into a drawer by hand, so the work is quick and simple and the productivity can be significantly improved.

In addition, the rail brackets are integrally bent on both sidewalls of the drawer body, and the rear plate assembly is quick and easy, so that there is no need to make a separate bracket and weld or weld the back plate as in the prior art, thereby significantly improving productivity. The cost saving effect is great.
