Description

  The present invention relates to the structure of a shelf board. A shelf board composed of a net part and a frame part, which replaces the conventional grille-like shelf board and adds an overall aesthetic appearance, as well as a vertically extended frame on the side of the frame. Assembling in a state where the shelf board is stably mounted on the shelf holder by fixing the inwardly-fitted ribs formed on the inside or the protrusion fitting ribs produced by press working into the inset fixing tank provided in the shelf holder It has the feature that it can be.

  A typical steel rack is usually an upright bar, and is provided with a tank for fitting a number of shelves into the bar. And the position of a shelf holder is adjusted as needed. Furthermore, the entire structure of the rack is configured by combining a shelf board with a fixed tank on the shelf holder.

  As shown in FIG. 1, the structure of the rack plate of this type is mainly formed by arranging and welding metal bars. After the welding of the vertical bars with the horizontal bars at the front and rear ends, and welding, the vertical bars are cut and flattened. At the same time, a bar which becomes a support column is attached to the lower side of the middle position of the bottom part to give strength to the surface on which the object is placed. In this way, the front and rear horizontal bars are accommodated in the fixed tank at the tip of the shelf holder, and the shelf board and the shelf holder can be assembled.

  However, when the above-described shelf board and shelf holder are combined, the assembly is performed simply by fixing the horizontal bars before and after the shelf board to the fixed tank of the shelf holder. The fixed tank is simply fixed back and forth with respect to the horizontal bar of the shelf, and there is no restriction on the upward direction. Therefore, the shelf board is easily separated from the shelf support by an upward external force, and is not ideal because of lack of stability in terms of the assembly structure.

  Furthermore, since this type of shelf board is formed by welding metal bars side by side, the entire assembling operation becomes very complicated and takes time. The appearance of welding can be easily seen on the appearance. Further, in the manufacturing process, after the rod is welded, the surplus portion must be trimmed, often the cuts are likely to be uneven, and sometimes the jagged edges can hurt the hand.

  The structure of the shelf board of the present invention solves the instability existing in the relationship between the conventional shelf board and the shelf holder, the aesthetics of the grill-type shelf board, and the safety disadvantages. The shelf board structure of the present invention is constructed by combining a net part and a frame part, and using the rib part provided on the horizontal frame above the frame part, the net part is assembled by welding and stable assembly is performed. The structure is possible. There are no weld marks that have aesthetic problems. In addition, when the vertical frame on the side of the frame is formed in an elongated shape, the inwardly folded portion or the protrusion fitting ribs provided at the ends of both sides are placed on the shelf holder attached to the rack. The shelf board is assembled in a stable state in the shelf holder, and is replaced with a conventional grill-like shelf board, so that the overall appearance is beautiful. In addition, it has the feature that the cut does not hurt the hand.

  Please refer to FIG. 2 to FIG. The structure of the shelf board 10 according to an embodiment of the present invention is configured by welding a frame portion 12 formed of an L-shaped frame to a metal net portion 11. Among them, each horizontal frame 13 of the frame portion 12 has a single rib portion 14 formed by pressing. The net part 11 and the frame part 12 can be stably coupled by being combined by welding. In addition, there are no weld marks that impair the appearance. Further, at the lower end of the vertical frame 15 on the side surface of the frame portion 1, there is a portion 16 that is folded inward and formed inward.

  On the lower edge of the vertical frame 15 on the side surfaces of the shelf plate 10 and the frame portion 12 described above, a portion 16 folded inward is provided. In the present embodiment, in view of the structural design of the shelf holder 20, an inset fixing tank 21 in which the vertical frame 15 in the frame portion 12 of the shelf board 10 is fitted is provided at the upper end thereof. A fitting tank 22 extends in the lower stage of the fitting fixed tank 21. When the shelf board 10 is placed on the shelf holder 20, the vertical frame 15 in the frame portion 12 of the shelf board 10 is fitted using the insertion fixing tank 21 of the shelf holder 20. The portion 16 folded inside the lower edge of the vertical frame 15 is caught in a fitting tank 22 extending from the fitting fixing tank 21. Thus, the shelf board 10 and the shelf holder 20 can be stably combined. Therefore, the shelf board 10 is not detached upward from the fitted fixed tank 21 by an external force.

  In other words, the present embodiment uses the net portion 11 in the structural design of the shelf board 10 to replace the conventional grill-like structure, thereby greatly simplifying the processing process and reducing the cost. Can be reduced. In addition, no welding marks are generated in the conventional type. Therefore, it can be said that the aesthetics are greatly improved. Furthermore, since the edge of the net part 11 is completely isolated from the frame part 12 and is not exposed, the hand is not injured. In addition, the inwardly folded portion 16 extending to the lower edge of the vertical frame 15 of the frame portion 12 meshes with the fitting tank 22 of the fitting fixing tank 21 of the shelf holder 20, so that the combination of the shelf board 10 and the shelf holder 20 is achieved. Being rigid, it solves the disadvantages that exist in the conventional type.

  Reference is now made to FIGS. This is another embodiment of the present invention. The shelf plate 30 is integrally formed by welding a frame portion 12 composed of a net portion 31 and an L-shaped frame. Among them, each horizontal frame 23 of the frame portion 32 is similarly formed with a rib portion 34 by pressing. The net part 31 and the frame part 32 can be assembled stably by welding. In addition, there are no weld marks that impair the appearance. In addition, there are protrusion fitting ribs 36 at positions close to both sides below the vertical frame 35 before and after the frame portion 32, and when the shelf board is placed on the shelf holder 20, the fitting fixing tank 21 of the shelf holder 20 is used. Then, the vertical frame 35 in the frame portion 32 of the shelf board 30 is fitted. And the protrusion fitting rib 36 in the position close | similar to the lower edge of the vertical frame 35 is caught in the fitting tank 22 extended from the fitting fixing tank 21. As shown in FIG. In this manner, the shelf board 30 and the shelf holder 20 can be stably combined. Accordingly, the shelf plate 30 is not detached upward from the fitted fixed tank 21 by an external force.

  Furthermore, the present embodiment is a shelf structure composed of a net portion and a frame portion, and a stable welded connection relationship with the net portion can be constituted by the rib portion of the frame portion. And by covering and isolating the edge of the net part, the hand is not injured. In addition, a stable assembling and connecting relationship with the shelf support is possible by the inwardly folded portion or protrusion fitting rib that extends from the vertical frame of the frame portion. Therefore. In manufacturing, another grill-type shelf board is produced by combining the conventional grill-like structure and the frame portion of this embodiment. However, the design of the frame portion is beautiful in appearance and excellent in safety. At the same time, it is possible to maintain a stable coupling relationship between the shelf board and the shelf holder. Therefore, it can be said to be an option in the consumer market.

  As described above, the rack shelf structure of the present embodiment uses the structure of the frame portion to combine metal net portions into a shelf plate, and in some cases, a grill-type structure in which metal bars are arranged. A shelf board is also possible. Regardless of the type, the design of the frame part is beautiful in appearance and excellent in safety. At the same time, the assembly structure of the shelf board and the shelf holder is stable. It solves various problems existing in the industry and has high industrial utility value and practicality.
