DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown.

The vertical member (10) of the present invention

A plurality of engaging grooves 12 and engaging grooves 14 are formed on the side surfaces of the engaging grooves 12 and the engaging grooves 12, And the engagement groove 14 and the engagement groove of the bracket 50 and the engagement groove of the bracket 50 and the engagement groove of the vertical member 10, (12) and the fastening groove (14).

In addition, the fastening groove 14 is repeatedly arranged in the form of a long hole and a circular shape, and the length of the vertical member 10 is not measured every time the number of the fastening grooves 12 is counted, So that the operator can cut the vertical member 10 by a necessary length and make it easy to use.

For example, when the gap between the slot and the slot of the fastening groove 14 is 30 cm and eight circular fastening grooves 14 are formed between the slot and the slot, The horizontal member 20 can be installed at a position desired by the operator so that the pedestal can be installed.

The horizontal member (20) of the present invention

And a coupling protrusion 22 provided between adjacent vertical members 10 after the vertical member 10 is arranged in a rectangular shape and fitted to the coupling groove 12 of the vertical member 10 from the outside, And two coupling projections 22 are formed on both sides of the coupling projections 22. The coupling projections 22 are formed in the coupling grooves 24 corresponding to the coupling grooves 12 of the vertical member 10, Respectively.

The horizontal member 20 is formed by bending a receiving portion 26 on the inner side of the assembled shelf in the upper portion of the horizontal member 20 (the inner side of the first shelf 100 in FIG. 1) to support the receiving plate 60, A fastening groove 25 is formed at a predetermined position on both sides of the support plate 60 so as to fasten the support plate 60 with a bolt.

In this case, since the coupling grooves 24 are formed in a similar manner to the coupling projections 22, they may be formed without any dependency on the bolts, and therefore, it is most preferable that only one coupling groove 25 be formed. It is preferable that a plurality of holes are formed so as to be penetrated regardless of any position of the receiving portion 26. [

In addition, when the first shelf 100 of a square shape is formed, the horizontal member 20 is provided on four sides, and when a shelf having the same height is formed on the side of the first shelf 100, A horizontal member 20 is provided on the surface and an extension member 30, which will be described in detail later, is provided on one side of the shelf so as to extend the shelf.

The connecting member (30) of the present invention

And a coupling protrusion 32 which is used to extend and connect the shelves without attaching the two shelves together and which is fitted in the coupling groove 12 of the vertical member 10 from the outside, Side portions 39 each having an engaging groove 37 and a fastening groove 38 at both ends thereof are bent outwardly so that the side portions 39 are bent in the outward direction, The engaging projections 32 and the engaging grooves 38 are formed in the bent opposite directions and are installed between the adjacent vertical members 10 on either side of the shelf where the horizontal member 20 is not installed.

1, the connecting member 30 is provided with a connecting member 30 on a neighboring vertical member 10 between the shelf and the shelf so that the receiving portion 34 of the connecting member 30 36 can support both the conventional lathe support plate 60 and the extended lathe support plate 60. [

At this time, the engaging projection 22 of the horizontal member 20 provided on the elongated shelf is engaged with the engaging groove 37 formed on the side portion 39 of the elongated member 30, 22 are joined to the vertical member 10, which is the column of the extended shelf.

In addition, it is preferable that the receiving portion 36 is welded. In this case, when the bolt is fastened, a protruding portion is generated and a long working time is required. It is most desirable to be coupled to the body of the connecting member 30 by welding.

The protective member (40) of the present invention

A protective member 40 is fitted to a lower portion of the vertical member 10 and is made of rubber or synthetic resin so that protrusions are formed on the inner side so as not to be easily detached after being coupled to the vertical member 10, It is preferable that a slip-preventing groove or the like is formed so as not to slip easily on the floor. This is because the conventional anti-slip pad or the like is manufactured to match the shape of the vertical member 10, and a detailed description thereof will be omitted.

The bracket (50) of the present invention

A bracket 50 is installed on a prefabricated shelf already assembled by using a vertical member 10 whose height is different from that of a vertical member 10 used in a prefabricated prefabricated shelf, (20) are combined with each other to realize a shelf extension.

That is, the bracket 50 is provided with the engaging projection 52 which is fitted into the engaging groove 12 of the vertical member 10 from the outside, the receiving portion 54 is bent outwardly at the upper portion, A side wall 59 having an engaging groove 56 and an engaging groove 58 is formed in an outwardly bending direction and is formed in the coupling groove 12 of the vertical member 10 adjacent to one side of the first shelf 100 (Not shown).

The bracket 50 is connected to one side of the horizontal member 20 by the side surface portion 59 and a vertical member 10 having a small length is provided on the other side of the coupled horizontal member 20, 10 are coupled to each other and the horizontal member 20 is coupled to the support plate 60.

It is also possible to use the bracket 50 instead of removing the receiving portion 36 of the connecting member 30. However, when the connecting member 30 is used, the body connecting the side portion 39 of the connecting member 30 (Not shown) serves as a horizontal wall at the middle height of the shelf so that the display of the articles can be limited, so that it is preferable to use the bracket 50 when extending shelves having different heights.

The vertical member 10, the connecting member 30 and the vertical member 10, the bracket 50 and the vertical member 10, the connecting member 30 and the horizontal member 20, The combination of the bracket 50 and the horizontal member 20 is characterized in that a portion where the engaging projections 22, 32 and 52 are fitted and protruded from the outside of the engaging grooves 12, 37 and 56 is minimized .

This is because, for example, when the horizontal member 20 is fitted to the vertical member 10 at the inner side of the vertical member 10, the coupling protrusion 22 protrudes to the outside, It is possible not only to prevent wear, but also to realize an effect that a beautiful appearance can be realized.

In other words, the conventional prefabricated prefabricated shelf can be fitted to the outside by changing the structure. However, the conventional prefabricated shelf may have a complex structure and protrude from other structures.

In one embodiment of the present invention, the engaging grooves 12, 37, 56

When the length of the top surface 1 is e and the length of the bottom surface 2 is e ', the length of e is greater than the length of e' and the length of the side surface 3 from the top surface 1 to the bottom The side surface 4 is formed to extend from the distal end of the side surface 3 to the lower surface 2,

When the length of the upper surface 5 is f and the length of the lower surface 6 is f ', the length of f is greater than the length of f', and the width of the side surface 7 decreases from the upper surface 5 to the lower direction And is formed to be narrowed.

5 (a) shows the structure of a conventional coupling groove, and FIG. 5 (a) shows a structure in which the length of the lower surface is smaller than the length of the upper surface, Can be confirmed. This is because the coupling protrusions are formed in the same shape so that they can be firmly engaged with each other. However, there is a problem that the height of the support portion may be varied due to loosening of the coupling due to wear and shock during frequent coupling or disassembly.

5a), when the distance between the upper surface 1 and the lower surface 2 is a, the side surface 3 is formed at a distance of b and the lower surface 1 2 and the side surface 4 is formed at a distance of c and extends vertically from the end of the side surface 3 to the lower surface 2. In other words, 5 (b) and 5 (c) show a front view of the coupling groove and the coupling projection of the present invention, respectively.

This is because even if the upper surface 5 of the engaging projection is fitted along the side surface 3 after the engaging projection is drawn into the engaging groove and the engaging jaw (undecomposed) created by the side surface 3 and the side surface 4 is worn, Can be maintained.

That is, even if the engagement jaws where the side surface 3 and the side surface 4 meet are worn, the engagement groove of the side surface 3 and the side surface 4 is disappeared, .

In another embodiment of the present invention, the engaging grooves 12, 37, 56

When the length of the upper surface 1 is e and the length of the lower surface 2 is e ', the length of e is greater than the length of e', the side surface 3 is formed vertically downward, 'Is narrower in the downward direction, and the side surface 4 extends from the end of the side surface 3 and is formed vertically to the lower surface 2,

The engaging projections 22, 32,

When the length of the upper surface 5 is f and the length of the lower surface 6 is f ', the length of f is smaller than the length of f', and as the side surface 8 goes downward from the upper surface 5 The side surface 9 extending from the distal end of the side surface 8 and being formed vertically to the bottom surface 6,

The length e of the upper surface 1 of the engaging grooves 12, 37 and 56 and the length of the lower surface f 'of the engaging projections 22, 32 and 52 are the same.

6, the side surface 3 of the coupling groove is formed vertically by a length b, and the side surface 3 'is tapered like the side surface 3 shown in Fig. 5b) And the side surface 4 is formed vertically to the lower surface 2. The coupling protrusions are formed such that the length of the lower surface 6 is longer than the upper surface 5 and widen toward the lower surface 6. The side surface 8 is wider toward the lower surface 6 by the length of b And the side surface 9 extends from the distal end of the side surface 8 and is formed vertically to the lower surface 6. At this time, e) and d) of FIG. And a front view of the projection.

That is, the engagement between the engagement groove and the engagement protrusion is engaged with the engagement protrusion formed on the engagement protrusion formed by the side surface 3 'of the engagement groove, and the lower surface 6 of the engagement protrusion is widened, Thereby achieving the effect of making a solid coupling. Since the side face 3 'and the side face 4 are kept tapered to the lower face 6 even if the side face 3' of the engaging groove is worn, the engagement of the engaging recess and the engaging protrusion can be maintained do.

In addition, fastening grooves 14, 24, 38 and 58 are respectively formed on the same surfaces of the defect grooves 12, 37 and 56 and the engaging projections 22, 32 and 52, The shelf can be tightened with bolts. This realizes the effect of preventing the shelf from being twisted even when a pressure such as an impact is applied to the completed prefabricated shelf.
