BACKGROUND OF THE INVENTION

The present invention relates to a prefabricated shelf which can be used to display or store various products or items in a shop or a warehouse, and in particular to a prefabricated shelf wherein a horizontal frame having an engaging slot is secured to a vertical frame which has a plurality of regularly arranged engaging protrusions, so a shelf panel can be engaged, thus easily and durably assembling a shelf without using any engaging means, for example, a screw, a bolt, etc., while providing an advantage in the way that the height of a shelf crosspiece of a vertical frame can be feely adjusted.

A shelf made of wood, etc. is being widely used. In recent years, such a shelf is being made of various materials, for example, a metallic frame and other various components in an effort to improve the easiness of assembling, disassembling and transportation. A very recently released product can be easily assembled or disassembled without using any engaging means, for example, a bolt, a screw or a tool. As an example of such a shelf, there is a prefabricated shelf of Korean Patent Application No. 20-2012-002372 wherein a horizontal beam is secured to a vertical beam using an engaging slit, etc., and the other side thereof in a longitudinal direction is arranged getting far from the vertical beam, which makes it possible to assemble or disassemble the shelf without using any engaging means. In this product, only one end of the horizontal beam is fixed to the vertical beam, and the other end thereof is configured to get far from the vertical beam. For this, there may be a limit in supporting the weights of a shelf itself and the items arranged on the shelf.

SUMMARY OF THE INVENTION

Accordingly, it is an object of the present invention to provide a prefabricated shelf wherein the weights of a shelf panel, items and others can be efficiently supported in such a way that an engaging slot formed at a horizontal frame is engaged to a plurality of engaging protrusions formed at regular intervals at a vertical frame.

It is another object of the present invention to provide a prefabricated shelf wherein it is possible that a shelf can be manufactured by engaging a vertical frame and a horizontal frame without using an engaging member, and the engaged vertical frame and horizontal frame can support the weights of the shelf panels and the items on the shelf panels.

To achieve the above objects, there is provided a prefabricated shelf which may include, but is not limited to, a vertical frame and a horizontal frame which is engaged to the vertical frame.

A plurality of engaging protrusions are formed at regular intervals at the left and right sides of the vertical frame. The horizontal frame having engaging slots that are engaged to the engaging protrusions. The horizontal frame may include a shelf panel engaging member, thus allowing the shelf panel to insert and engage. A plurality of the horizontal frames are engaged to 4 vertical frames, and the shelf panels are engaged to the shelf panel engaging member of the horizontal frame, thus manufacturing a prefabricated shelf.

In the prefabrication shelf of the present invention, a shelf can be assembled in such a way that a horizontal panel made of a horizontal flat plate can be easily and reliably engaged to a vertical frame without using a separate engaging means, for example, a screw, a bolt, etc., and the shelf panels can be easily and quickly mounted.

Since a plurality of engaging protrusions are provided at regular intervals at the vertical frame, it is possible to freely adjust the heights of the shelf panels, if necessary, by using the engaging slots of the horizontal frame to which the shelf panels are engaged, thus maximizing the applicability of the prefabricated shelf.

DETAILED DESCRIPTION OF THE INVENTION

The present invention will be described in detail with reference to the present invention.

The present invention is directed to a prefabricated shelf which may include, but is not limited to, a vertical frame10, a horizontal frame20, and a shelf panel30.

More specifically, in order to assemble a box-shaped shelf without using a separate engaging member, the vertical frame10having an engaging protrusion11and the horizontal frame20having an engaging slot21are used. The horizontal frame20is connected between the four vertical frames10, the shelf panel30is inserted and engaged between the horizontal frames20, thus fabricating a shelf in a multilayer structure the height of which can be adjusted.

More specifically, as illustrated inFIG. 2, a plurality of engaging protrusions11are arranged at regular intervals at the left and right sides of the vertical frame10.

Namely, the engaging protrusion11is engaged to or formed at a quadrangular perforation portion12at the left and right sides of the vertical frame10. A plurality of the quadrangular perforation portions12are arranged at regular intervals. A U-shaped or center-open U-shaped engaging protrusion11is formed at or engaged to both sides of each perforation portion12. When the engaging protrusion11is engaged to the engaging slot21of the horizontal frame20, since the U-shaped or center-open U-shape plays a role of an engaging portion11awith respect to the engaging slot21of the horizontal frame, as illustrated inFIG. 4, it is possible to maintain a durably engaged state.

Here, the horizontal frame20is formed in a C-shape the open side of which becomes an open shelf panel engaging portion23to which the shelf panel30is engaged, and at the closed side of the other side or the center portion of the upper side24, as illustrated inFIG. 1, a quadrangular horizontal slot26is formed sunk in a longitudinal direction. As illustrated inFIGS. 1, 3 and 4, the engaging slot21is formed of a lower side engaging slot21band an upper side engaging slot21a. The upper and lower side engaging slots are formed in the U-shaped or center-open U-shape and are arranged at the same intervals as the intervals of the two engaging protrusions11. The two engaging protrusions11are engaged to the upper and lower side engaging slots21aand21b, respectively. The upper side engaging slot21ais perforated from an upper side wall surface26aof the sunk horizontal slot to the upper surface24of the horizontal frame20. The lower engaging slot21bis perforated in a U-shaped or center-open U-shape from the side surface of the horizontal fame20to the upper surface. To this end, the engaging protrusion11of the vertical frame10, as illustrated inFIG. 4, can be inserted into the perforated portion formed at the upper side wall surface26aand the side surface25of the upper and lower side engaging slots21aand21bof the horizontal frame. When the horizontal frame20is pressed from top to bottom, the engaging protrusion11will enter the perforated portion21cof the upper surface24of the upper and lower side engaging slots21aand21b, and the engaging member11aof the engaging protrusion11can be stably fixed at the upper surface24of the horizontal frame20by an engaging fixing member22formed between the perforation portions21c.

In addition, when it needs to disengage the horizontal frame20from the vertical frame10, the engaged horizontal frame is pressed from bottom to top, thus disengaging the horizontal frame20. Thereafter, the shelf panel is engaged to the open shelf panel engaging portion23, and books or items are put on the upper surface24. In this state, since the weight applies downward thanks to gravity, the shelf or the horizontal frame20will be disengaged from the vertical frame10, thus obtaining a stable engagement without any wobbling.

The shelf panel30can be engaged through the open shelf panel engaging portion of the horizontal frame20, thus manufacturing a prefabricated shelf.

As illustrated inFIG. 7, since the vertical frame10may include a plurality of engaging protrusions11at upper and lower sides, and the horizontal frame20is engaged with the engaging protrusion11of the vertical frame10, so the shelf panel30can be freely installed at a height that a user wants and can be configured in a form of multiple layers.

As illustrated inFIG. 2, a plurality of engaging protrusions are formed at regular intervals at the left and right sides of the vertical frame10, and the engaging protrusions formed at the outer most portion between the left side or the right side may be used when it needs to expand the shelf.
