Description

Shelf rack assembly structure

The present invention relates to an assembly structure of a shelf rack capable of mounting shelves in multiple stages by cutting an angle to a certain length, and more particularly, by improving the assembly structure of vertical members and horizontal members, fine height adjustment is possible while assembly parts are It relates to a shelf rack assembly structure that is not exposed to the outside.

In general, prefabricated rack shelves are used in a variety of ways for the purpose of displaying or storing items not only in stores or warehouses, but also in homes and offices. can be provided, so it is used in various fields.

In the early shelf racks, the angle was cut to an appropriate length to provide a vertical support, the connecting part was fixed with a separate piece of hardware, and then a shelf such as plywood was placed on it and various items were loaded.

However, since it is a structure assembled by a bolt and nut method, assembly and disassembly are very cumbersome, and there is a problem that drift occurs even when the assembly is completed.

Therefore, as an improvement on this, it was introduced as Public Utility Model No. 20-2010-0008790 'Prefab Rack Shelf' (Prior Art 1).

The above shelf rack is currently the most popular and widely used as a method of fixing a horizontal bar to a hole by forming a perforated hole in a vertical support without using a separate fixture, as shown in FIG.

However, although this shelf rack has the advantage of being easy to disassemble and assemble, there are problems such as poor aesthetics because the assembly part is exposed to the outside, and clothes are caught and torn due to the exposed assembly part.

In particular, in recent years, there is a lot of demand for shelf racks for organizing at home or in offices, and in the case of infants and toddlers, there is a risk of safety accidents due to the exposed assembly parts.

Therefore, recently, as shown in FIG. 2 , a method of preventing the assembly part from being exposed to the outside has been proposed, and it was introduced as Utility Model Registration No. 482530 'Angle shelf frame' (prior art 2).

However, there is a problem in that it is difficult to accurately set the shelf height when assembling the shelf rack because there are too many holes formed in the vertical member in the case of the prior art 1 as well as the prior art 2 above.

That is, a very large number of holes are formed in the vertical member for adjusting the height of the shelf, and since the holes are arranged at very tight intervals, the hole height of the vertical member located on the left and right sides of the shelf is the same. It is very difficult to fit and fit, and installation is difficult because you have to set the position while counting the number of holes.

If the installation location of the left and right sides is different even by one space, it is impossible to install the shelf or there is a problem in that the shelf is installed at an angle. There is a problem that it cannot be reused or that the rack is twisted.

In particular, since the load is concentrated inside the bent part of the hanging part in the part receiving the load of the hanging part, the hanging part is easily deformed or bent, and the shelf moves gradually as well as dropping and breaking the product in the display state. The product stability is greatly reduced as the product becomes tilted or tilted.

In addition, due to this assembly structure, the process for manufacturing the vertical and horizontal members constituting the rack is cumbersome, and in particular, in order to prevent the fastening part from being exposed to the outside, the manufacturing process becomes more complicated, which greatly reduces the productivity of the product. works as

The present invention is to solve the above problems, and simplifies the assembly structure without exposing the assembly part of the shelf rack to the outside to facilitate disassembly and assembly, and provides a shelf rack assembly structure in which the height of the shelf can be finely adjusted. It is an object of the present invention to provide.

In addition, it is another object of the present invention to simplify the structure of the component parts of the shelf rack, including the vertical member and the horizontal member, and to manufacture it at a low cost.

The present invention as a technical idea for achieving the above object is provided with a frame body so that the vertical members constituting the pillars of the shelf rack are connected by horizontal members to form a certain frame and accommodate the shelf, and the frame body is vertical In the shelf rack assembly structure in which the assembly is made by a connecting means connecting a member and a horizontal member, the connecting means has an installation bracket mounted on a vertical member, and a hook part is formed at an end of the horizontal member, and the hook part is hooked to the installation bracket and fixed and the installation bracket is mounted to be movable up and down in the vertical member so that the mounting height of the horizontal member can be adjusted, and a locking element for fixing the height adjustment state of the installation bracket with respect to the vertical member is provided. In a state where the bracket is fixed to the vertical member, the horizontal member is hung so that the assembly is made.

In addition, the installation bracket is inserted into the rail part formed on the vertical member so that the up and down sliding operation is made so that the height can be adjusted. The installation bracket is assembled to be in contact with the inner surface of the vertical member, but at both ends of the vertical member in the width direction, locking jaws are formed so that both ends of the installation bracket in the width direction are caught, so that the up and down slide operation of the installation bracket is made.

According to the shelf-rack assembly structure of the present invention, fine height adjustment is possible by the slide structure, so that it is possible to customize installation according to the purpose of the display or the characteristics of the display place.

In addition, since the assembly part is not exposed to the outside, the aesthetics is beautiful, and it is possible to prevent side effects caused by exposure of the fastening part, for example, injuries caused by clothes caught and torn during movement, or objects caught during transport.

In addition, it can be manufactured in a simple process by extruding and cutting the vertical and horizontal members, which are the materials that take up most of the weight and volume in the shelf rack structure, and the bracket and hanger also have a simple structure, so the production process and manufacturing cost can be significantly reduced. Therefore, it is possible to supply high-quality products at low cost.

In addition, since the fastening structure of the horizontal members of the front, rear and both sides of the shelf rack is the same, related parts can be minimized, and the front, rear, and both sides of the shelf can be assembled together at the same height for each floor of the shelf. It can prevent the rack from being twisted in any direction, front, back, left or right, and greatly improve the durability of the shelf rack.

In addition, there is an advantage that the shelf rack can be installed independently, and since there is almost no inclination in a state where the horizontal member spans the vertical member, it can be used as a wall-mounted type.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the present invention, as shown in FIGS. 3 to 5 , the frame body 1 is assembled by the connecting means 2 to constitute a shelf rack, and the frame body 1 is horizontal with the vertical member 100 . It is composed of a member 200 , and the connecting means 2 is composed of an installation bracket 10 mounted on the vertical member 100 and a hook portion 20 provided on the horizontal member 200 .

The vertical member 100 constitutes the pillar of the shelf rack, and the vertical member 100 is connected by the horizontal member 200 in a state in which they are arranged at regular intervals to provide a frame of a certain shape, and the frame is provided. After that, a shelf can be inserted and used as a shelf rack.

The vertical member 100 and the horizontal member 200 are located on the inner side, that is, on the inner side that is not exposed to the outside in the assembled state of the shelf rack, the part where the installation bracket 10 and the hanger 20 are assembled. , as the surface exposed to the outside covers the assembly part, the assembly part is not exposed to the outside at all.

The surfaces of the vertical member 100 and the horizontal member 200 may be finished in a smooth pattern to form a neat aesthetic, and if necessary, the surfaces of the vertical member 100 and the horizontal member 200 may be embossed or engraved on the surface of the surface. A figure and the like may be displayed.

The installation bracket 10 is mounted to be movable up and down in a state of being mounted on the vertical member 100 so that it is possible to adjust the installation height of the horizontal member 200, and the installation bracket 10 has a coupling hole 12 This is formed so that the hook 22 of the hook part 20 is fitted into the coupling hole and can be hooked and fixed.

At this time, the installation bracket 10 is to be able to adjust the height of up and down while mounted on the vertical member 100 , and the up and down height adjustment is to form a rail part 110 on the inner surface of the vertical member 100 . And, by inserting the installation bracket into the rail part and assembling it, it is possible to adjust the height up and down in a slide manner while the installation bracket is seated on the rail part.

The assembly structure of the vertical member 100 and the installation bracket 10 will be described in more detail as follows.

The assembly of the rail structure of the vertical member 100 and the installation bracket 10 is performed by providing a rail portion having a shape to be inserted into the vertical member, and providing a rail portion protruding to be inserted into the rail portion on the outer surface of the installation bracket 10. The slide operation can be made, but in order to simplify the structure and facilitate assembly, as shown in FIG. 6, the vertical member 100 and the installation bracket 10 have cross-sections ' It has a L-shaped cross-sectional structure, and the installation bracket 10 is assembled to be in contact with the inner surface of the vertical member 100, but the installation bracket 10 has a structure that does not separate from the vertical member 100 so that it slides up and down can make it work.

That is, at both ends of the vertical member 100 in the width direction, the hooking jaws 112 are formed so that the edges 11 of both ends in the width direction of the installation bracket 10 are caught, so that the installation bracket 10 is in close contact with the vertical member 100 . In the mounted state, it is possible to make an up and down slide operation without being separated arbitrarily.

At this time, since the vertical member 100 is implemented to maintain the same structure in the longitudinal direction for accommodating the installation bracket 10, it can be manufactured simply by extrusion molding of an aluminum bar or the like.

In addition, the installation bracket 10 can configure the fastening surface 14 in close contact with the inner surface of the vertical member by bending the plate material close to the 'L' shape, and bending the bent portion to have an inclined surface.

And by bending the installation bracket 10 to be close to the 'L' shape in this way, when inserting into the vertical member 100, there is no need to combine the installation bracket 10 from the end in a rail manner, as shown in FIG. 7 . ), it can be assembled by inserting it in one-touch by the self-elasticity of the mounting bracket by the forced pressure method.

At this time, the installation bracket 10 is closely fixed to the inner surface of the vertical member by the force to be restored while both wings of the installation bracket 10 are spread outward, and the slide operation is performed in this state.

On the other hand, the installation bracket 10 is to be able to function as a shelf by maintaining a constant height after the height adjustment is completed in the vertical member 100, and fixing the height adjustment state of the installation bracket 10 A locking element 30 for doing so may be further provided.

In the locking element 30, a piece fastening hole 32 is formed in the installation bracket 10, and a piece fastening groove 34 is formed in the vertical member 100 to set the position of the installation bracket by fixing the piece 36. Through the fixing of the pieces, the installation bracket 10 can be maintained at a constant height without sagging in the state in which the shelf rack is assembled.

The installation bracket 10 may have a plurality of coupling holes formed at regular intervals along the longitudinal direction.

Therefore, even if the height is fixed by the locking element 30 in a state in which the installation height of the horizontal member 200 with respect to the vertical member 100 is set, the installation height of the horizontal member 200 can be adjusted in multiple stages, so adjusting the height of the shelf This becomes possible.

At this time, as shown in FIG. 8 , the hook part 20 provided at both ends of the horizontal member 200 is configured to be separated from the horizontal member 200 and fitted into both ends of the horizontal member in the longitudinal direction. It can be configured to be assembled, and since both the vertical member 100 and the horizontal member 200 constituting the frame body 1 have a cross-sectional structure having continuity, the vertical member 100 and the horizontal member 200 All can be manufactured simply by extrusion molding, and manufacturing costs can be greatly reduced by simplifying the manufacturing process of materials that are relatively bulky and have a large proportion of manufacturing costs.

The hooks 20 assembled to both ends of the horizontal member 200 can form the hooks 22 to protrude by press working using a plate material as a raw material, in which case the hooks 22 are bent on both sides in the horizontal direction. Formed and inserted into the coupling hole 12 of the installation bracket 10 to ensure sufficient support for vertical load, and even if a heavy object is placed and a large vertical load is applied, the shape of the hook 22 is not easily deformed and is firmly is fixed

In addition, the coupling hole 12 formed in the installation bracket 10 is formed to have an inclination toward the lower side so that when the hook is inserted, it is inserted and guided along the inclined surface so that it can be easily hung and fixed, and the coupling hole 12 and the hook ( 22), by forming the engaging portions 13 and 23 corresponding to each other, it is possible to prevent the hook 22 from being easily separated arbitrarily while being inserted into the coupling hole 12 .

At this time, if the coupling hole 12 and the hook 22 are configured in multi-stage, such as two or three stages, upward and downward, the horizontal member is mounted in a state in which it is horizontally maintained with little inclination in a state in which the vertical member is draped over the vertical member. Therefore, as shown in FIG. 12, the shelf rack can be used as a wall-mounted type.

And in this case, the horizontal member 200 is hung on both sides to fix it and the shelf is inserted, and a closing cap may be additionally configured to prevent the shelf from falling out, and the closing cap is formed to correspond to the cross-sectional shape of the horizontal member. Thus, the cross section of the horizontal member is not exposed and the aesthetics can be improved.

And when the vertical load is generated by press-working the plate material, the hanger 20 is dispersed throughout the plate material rather than being concentrated in a local area, thereby further preventing damage to parts.

In addition, the rail unit 210 may be formed on the inner surface of the horizontal member 200 so that the hanger 20 can be assembled to the horizontal member 200 by a slide method or a forced pressure method.

To this end, the part to which the hook part 20 is assembled is bent close to a 'L' shape, and the rail part 210 on which the assembled part is mounted is the width of the hook part 10 on the inner surface of the horizontal member 200 . The locking jaws 212 are formed so that both ends in the direction are hooked, so that the hooking part 20 can be simply inserted into the horizontal member 200 in a slide manner and assembled.

At this time, a piece hole is formed in the hook part so that the piece can be assembled with the horizontal member 200, and in the assembled state, it is possible to prevent arbitrarily falling out and not to flow.

And by bending the assembly part of the hook part 20 to be close to the 'L' shape in this way, when inserting it into the horizontal member 200, there is no need to combine the hook part 20 from the end in a rail manner, as shown in FIG. After putting on only a part of the part 20, it can be assembled with one touch by the self-elasticity of the tongue part in a forced pressure method.

At this time, the hook part 20 is closely fixed to the inner surface of the horizontal member by the force to restore while both wings of the hook part 20 are spread outward, and the slide operation is made in this state.

At this time, since the hook part is made of a plate material, the remaining part that is not bent, that is, the part on which the hook is formed, can be used as a handle to be easily fitted and assembled.

Therefore, as shown in FIG. 10 , after assembling the installation frame 10 to the vertical member 100 first, the assembly can be easily accomplished by inserting the horizontal member 200 in a state where the installation frame is positioned at a constant height. , since the assembly part is located on the inner surface of the vertical member and the horizontal member, the assembly part is not exposed at all to the outside.

At this time, the horizontal member 200 is formed in a '┣' shape so that the outer surface maintains a flat surface, and the middle bar is seated on the bent upper surface of the hanger 20 to be stably supported, as well as to the upper side of the middle bar can prevent the edge of the shelf from being exposed to the outside by the screen formed on the upper side of the horizontal member in a state in which the shelf is accommodated.

At this time, the installation bracket 10 can be assembled by mounting the horizontal member 200 on the front and rear surfaces of the shelf rack by symmetrically forming the through-holes 12 on the wings on both sides, and also horizontally on the side surfaces of the same height. By mounting and assembling the member 200, all four directions of the shelf rack are assembled by horizontal members, thereby minimizing torsion in the state where the shelf rack is installed. Twisting can be further prevented.

On the other hand, as shown in FIG. 11, the locking element 30 is an elastic body auxiliary support member 38 between the installation bracket and the vertical member 100 in order to strengthen the fixing state of the installation bracket 10 and prevent sagging. may be inserted to support the lower end of the installation bracket 10 .

At this time, the auxiliary support member 38 may be an elastic material such as rubber or silicone. As the width of the support member 38 increases, the vertical member 100 and the installation bracket 10 can be securely fixed.

The locking element 30 fixes the installation bracket 10 to the vertical member 100 in a manner by assembling the above-described piece 36, or utilizes the auxiliary support 38. It is possible to selectively use so that the fixing is made, but more preferably, it is possible to prevent the sagging of the installation bracket 10 by using the piece and the auxiliary support in parallel.
