ASSEMBLY SHELVES

TECHNICAL FIELD

The present invention relates to assembly furniture, and more particularly to assembly shelves of which the shape and/or dimension can be Changed by changing the assembling manner of shelf modules. Additionally, an assembly shelf according to the present invention can be combined with other structures such as prefabricated table and/or door structures, so that they are more useful and aesthetic.

BACKGROUND ART

The US Patent No. 4153311 relates to assembly furniture, including at least one connecting board for connecting at least two juxtaposed sectional units or columns of stacked section units, the connecting board having at opposite ends shelf portions capable of interlocking with side and rear wall sections of the respective units and a connecting portion interconnecting the two juxtaposed units or columns at a predetermined space form each other. This invention only creates shelves having rectangular drawers and the interlocking does not ensure a firm structure for shelves.

The KR Patent No. 1013383610000 relates to modular shelves assembled from many small and large modules. A modular shelf comprises connecting boards having some slots and connecting convex edges at lateral ends; and different corner members having connecting trenches whose lengths and widths fit with the connecting edges. The boards of small and large modules have same thickness and height. The disadvantage of these shelves is the small size of corner members, so it needs a high technique and better material to manufacture such parts and increase the cost price; additionally it also can make the linkage not stable and strong.

SUMMARY OF THE INVENTION

The present invention provides assembly shelves with the consideration of the disadvantages of existing solutions as mentioned in the background art above.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the invention will be described below with references to the enclosed drawings.

As presented on Fig. 1 , an assembly shelf according to this invention comprises boards T (of type T and/or T") and corner members G of different types used for flat or angle assembling between boards T and/or

T"

Fig. 3 presents a structure of the board of type T' made of MDF comprising a rectangular Ta having pairs of edges T1 and T2, a bar Tc connecting between a pair of edges T2 for reinforcing the board. Trenches T3 and T4 are provided on pairs of edges T1 and T2 respectively by using ordinary woodworking machines that a person with ordinary skill in art can easy use it. The bars of the frame Ta can be fixed with each other by ways of pasting, nailing, screwing or the like. Similarly, slabs Tb made of MDF with the think of several millimetres can be fitted to the surfaces of the frame Ta by pasting, nailing, screwing or the like. The formed rectangular T is a fat, slight and strong.

Fig. 2 presents several types of corner members G, each member G has the length equal to the one of edge T1 of the board T and has convex edges G1 for fitting with trenches T3 of the board T. Different types of corner members G are used for different connection positions of assembly shelves, namely: The corner member Ga is for perpendicularly assembling among two boards T connected with it; the corner member Gb is for 90° angle and 120° angle assembling between two boards T of three boards T boards connected with it; the corner member Gc is for perpendicularly assembling between two boards T of four boards T connected with it; the corner member Gd is for 120° angle assembling between two boards T connected with it; the corner member Ge is for 60° angle assembling between two boards T of three boards T connected with it; and the corner member Gf is for flat (180° angle) assembling between two boards T connected with it. A person having ordinary skill in the art can easily create other types of corner members G using for the same purpose of assembling boards T with each other for creating assembly shelves having different shapes and dimensions.

In one option, one of two bars containing edge T2 of the frame Ta and the bar Tc can be made and attached to other related bars via detachable connections such as screwing (not illustrated). The length of detachable bar containing the edge T2 is limited by bars containing edges T1. By this way, it can utilize the frame Ta to made the frame Td by removing the detachable bar containing the edge T2 and the bar Tc from the frame Ta.

In the Figs. 4 and 5, the trench T3 has trapezium cross section trapezium of which the - longer --side -of -parallel-sides- is the inside one, meanwhile the trench T4 has rectangular cross section. The deepness of these trenches and the material thickness are counted appropriately for ensuring strength of the connections as well as of the assembly shelves. Normally the material thickness is about several centimeters, and the deepness of trenches is around 1 centimeter.

Figs. 7, 8, 9 and 10 present the structure of a board of type T" made of MDF. The board of type T" comprises a frame Td formed with the manner similar to the one for forming the frame Ta or formed from the frame Ta by removing the detachable bar containing edge T2 and the bar Tc As presented above. The board Te has slots T5 arranged equidistantly from each other, and simultaneously, distances from each edge T1 to the first slot T5 at the same side are equal to each other and equal to the distance between adjacent slots T5. The board Te is tightly fitted to the inside the frame Td by using nails, screws or the like. Two slabs Tg having si milar structure to the slabs Tb, but further having slots corresponding to slots T5 of the board Te are fastened on the surfaces of the frame Td with the board Te already fixed thereon, thereby the flat, firm rectangular board of type T" is created. .

Fig. 11 presents an assembling mode of boards of type T" using the corner members Ga. Accordingly, the convex edge G1 of the corner members Ga is fitted to a trench T3 by sliding relatively the convex edge G 1 and a trench T3 with each other from one end of the edge G1 until they are tightly fitted with each other.

Fig. 12 presents an another assembling mode of the assembly shelf according to the invention, by using the boards of type T' and corner members Gd, Ge to create hexagonal with open shelf rooms. Fig. 13 presents an another assembling mode of the assembly shelf according to the invention by using the board of type T", corner members Ga, and fitting trenches T5 on different boards with each other in order to create rectangular or square with open shelf rooms in different dimensions. In use, people can place assembly shelves in accordance with the present invention on a surface, such as ground, or hung them on a wall by using support devices.

Fig. 14 presents a prefabricated door structure C suitable for assembling with corresponding rectangular shelf room. The door structure C comprises a frame C1 containing convex edges C2 for fitting respectively to trenches T4 of the boards T of the corresponding shelf room for which the door C is desinged (not illustrated). The door wings C3 are connected with the frame C1 via door-hinges (not illustrated) which can be easily performed by a person having ordinary skill in art, so that the door wings C3 can be operated for closing or opening the shelf room.

Fig. 15 is a simplified front view of a prefabricated table structure B for assembling with an assembly shelf of the present invention in order to create more utilities for it. This prefabricated table structure B comprises a plate B1 having a convex edge B2 along one its edge at the inside end of the plate B1 , which can tightly fit with a trench T4 of the boards T. Table- legs mounted to other, end of the plate B1 for supporting the plate at horizontal position when the table is assembled to the assembly shelf by fitting convex edge B2 with a trench T4. The legs B3 are foldable mounted to the plate B1 for convenient storage. The foldable connection between legs B3 and the plate B1 can be easily performed by a person having ordinary skill in art.

EFFECTS OF THE INVENTION

Assembly shelves according to the present invention are simple, easy to manufacture and convenient for using, transporting and storage.

Materials for manufacturing these shelves are popular and cheap, and therefore the finished products will have low costs. Additionally, it can utilize plywood, small wooden bars as materials for manufacturing assembly shelves in accordance with the present invention.
