Shelf assembly for preserving articles {Shelf assembly for preserving article}

The present invention relates to a prefabricated shelf for hanging and displaying or loading various items. More specifically, the present invention relates to a shelf assembly for storing items that is configured to easily attach and detach the shelf using brackets mounted on metal square pipes. It's about.

Recently, there has been an increasing trend in the use of metal angles, which are relatively cheaper and have superior rigidity than expensive materials such as raw wood, for general display cases and storage cabinets. By arranging the shelves in between in multiple stages, you can easily display or stack various types of items.

Most of these prefabricated metal angles are a common method of assembling using fastening means such as bolts or nuts between holes drilled at regular intervals in each frame, so they have excellent sturdiness, but the work time for assembly or disassembly is high. Not only does it take a long time, but there is also the inconvenience of having to use separate tools.

In addition, if the binding force of the angle is relaxed or the flatness of the shelf is not correct, the structure itself becomes unstable due to an abnormality in the center of gravity, and there is also a risk of collapse.

Recently, technologies related to various structures have been developed that enable fast and simple assembly without the need for separate fastening elements by allowing vertical and horizontal angles to be connected to each other by punching or bending them.

In relation to this angle fastening method, the technology disclosed in Domestic Patent Publication No. 2002-0089286 or Registered Patent No. 1092143 forms a slot in the longitudinal direction of the vertical angle and a fitting piece in the horizontal angle, enabling fastening without using bolts. However, due to the complex structure of each frame, manufacturing is not easy and productivity is low, assembling and disassembly work requires skill, and due to fluidity, the shelf cannot be installed stably.

In addition, various fastening methods are shown in domestic registered patents No. 1387645, 1845802, etc., as well as registered utility model Nos. 0228609 and 0473792, but the binding force between vertical and horizontal angles is structurally weak, so they cannot be closely adhered and there is a gap. This poses a problem in that prefabricated shelves cannot be used for a long period of time.

Public Patent No. 2021-0021433 (published on February 26, 2021) - Horizontal angle for prefabricated shelves. Registered Patent No. 1775656 (registered on August 31, 2017) - Boltless prefabricated angle assembly. Registered Patent No. 1840257 (registered on March 14, 2018) - Prefabricated angle. Registered Patent No. 2075150 (registered on February 3, 2020) - Boltless prefabricated angle structure and angle assembly using the same.

In addition, the present invention simplifies the components such as support brackets and shelves mounted on the frame, so that anyone can easily assemble or disassemble, improve production efficiency during manufacturing, and secure price competitiveness. The object is to provide a shelf assembly for storing items.

The present invention for achieving this purpose includes a frame made of square pipes with a perforated groove formed on one wall and disposed at all four corners, a support bracket fitted into the perforated groove of the frame so as to face each other, and It consists of a shelf that is mounted and fixed on these support frames, and upper and lower fixed bars that are inserted into the upper and lower ends of the left and right frames as a set, and the perforated grooves formed in the frames have a width. Narrow vertical grooves are formed in succession from the center of the wide horizontal groove, and the support bracket is configured so that a horizontal surface on which a through hole is formed and a vertical surface on which a pair of locking pieces are formed are integrally connected.

In addition, a support piece is integrally formed on one side of the vertical surface constituting the support bracket, so that it can be configured to be in close contact with one side of the frame during the process of assembling the support bracket, and a binding member with insertion rods formed at both ends is installed between the frames. Therefore, it is possible to install the frame by extending it vertically.

Due to the features described above, in the present invention, two sets of perforated grooves are formed at predetermined intervals on one side of each pipe constituting the frame, so that the sturdiness can be maintained during the insertion of the support bracket, as well as the upper ,The lower fixed bar can reliably suppress the fluidity of the frame.

In addition, the support piece formed on the support bracket can further strengthen the adhesion to the frame, and at the same time, the support bracket and the shelf can be easily fixed, and it is also possible to use it as a hanger for clothes by attaching a hanging rod.

In addition, the height of the frame can be freely adjusted using the binding member, and since the shelf is configured to be fixedly installed as a fastening element on the support bracket, assembly work can be performed much more easily than before and a stable structure can be achieved. .

Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the accompanying drawings, but the specific structures and functions they have are not limited to the embodiments described in this specification since they represent one configuration example.

First, as a preferred example to which the present invention is to be applied, the core technology disclosed in Pre-registered Patent No. 1724106 will be extracted and explained, and the resulting problems will be derived, and then the configuration and effects of the present invention will be described later.

As shown in the attached FIGS. 1 to 4, the angle post 10 is made of a steel plate bent in an approximately L-shape, and at the same time, a plurality of insertion grooves 11 are provided on each side of the angle post 10. It forms a long hole in the direction in which it extends.

In addition, the connecting stand 20 connects the angle posts 10, which serve as pillars, to each other in the horizontal direction, and one or more hooks 23 that are inserted into the insertion grooves 11 of the angle posts 10 are formed. This hook 23 is formed on the coupling surface 21 of the connecting bar 20 that comes into contact with the angle post 10, so that the user can easily couple the connecting bar 20 between the angle posts 10, and the coupling surface 21 It is formed by bending after some blanking is done through a press mold.

Accordingly, the hook 23 is formed with a vertical crossing surface 23a that is bent in the vertical direction on the coupling surface 21, and is bent at an approximately right angle on this vertical crossing surface 23a to form a vertical contact surface 23a with the coupling surface 21. It consists of a horizontal crossing surface (23b) formed in a parallel shape. If necessary, a guide surface 23c may be formed that is bent at a certain angle on the horizontal crossing surface 23b.

In addition, the reinforcing portion 30 is formed over the hook 23 of the connecting rod 20 and a portion of the engaging surface 21 on which the hook 23 is formed to reinforce the hook 23. This reinforcement part 30 is simultaneously processed through a press mold to form the initial hook 23, and a protruding surface 31 is formed on the surface of the reinforcement part 30 and a groove surface 32 is formed on the rear surface. It consists of a structure.

However, in the prior art as described above, since the reinforcement part is processed into the hook formed on the connection bar, a separate work process or time is required, and the worker inserts the insertion piece of the horizontal member into the slot of the vertical member and connects it to the horizontal member. In order to fix the member so that it does not shake, the fitting piece must be pressed and forced into close contact with the vertical member, which causes the problem of very poor workability.

Moreover, if the fitting piece is not pressed securely, the horizontal member will move because the forced connection is not made, and the fixing force will be reduced. Also, if the inserting piece is forcefully coupled to the vertical member, it will be difficult to separate the horizontal member from the vertical member again. It contains an unreasonable problem that can be very difficult to do.

In consideration of all problems in the prior art, the present applicant seeks to propose a shelf assembly for storing goods that can be maintained more robustly and stably as well as making assembly and disassembly easier, and this is shown in Figures 5 to 5 attached. This is explained in detail with reference to 12.

As shown in these drawings, the present invention includes a frame 50 made of square pipes and disposed at all four corners, a support bracket 60 fitted to each frame 50 so as to face each other, and this support. It consists of a shelf 70 mounted on and fixed to the frame 60, and upper and lower fixing bars 80A and 80B respectively inserted into the upper and lower ends of the frame 50 forming a pair on one side.

The frame 50 has a ㅁ-shaped cross-section, and perforated grooves 51 are formed in a row along the longitudinal direction on one wall, and the support bracket 60 is inserted into the frame to be assembled. At this time, the perforated grooves 51 allow the support bracket 60 to be assembled by combining two of them into one set, so that the support bracket 60 can be maintained stably, and the support bracket 60 can be maintained stably at the assembly position. Accordingly, the height of the shelf 70 can be freely adjusted.

In addition, in the case of the perforated groove 51 formed in the frame 50, it consists of a relatively wide horizontal groove 52a and a narrow vertical groove 52b, and a vertical groove 52b is located at the center of the lower end of the horizontal groove 52a. As the grooves 52b are formed sequentially, once the support bracket 60 is assembled, it can be prevented from coming off due to external force.

Meanwhile, the binding member 55 can be restarted at the end of the frame 50 and the frame 50 manufactured to a predetermined standard can be installed by vertically extending each other. That is, the binding member 55 is installed by assembling it at the end of the frame 50 made of square pipes as the fitting rods 57a and 57b are formed symmetrically up and down at both ends of the body 56a and are manufactured in an H shape. The height of the frame 50 can be appropriately adjusted depending on the location.

The support brackets 60 are installed by being inserted into the perforated grooves 51 of the left or right frames 50 forming a set so as to face each other. The support bracket 60 is formed in an L shape by integrally connecting a horizontal surface 62 on which a through hole 61a is formed and a vertical surface 64 on which a pair of locking pieces 63a are formed.

In addition, at the center of the area where the horizontal surface 62 and the vertical surface 64 are connected, a reinforcing piece 65 protruding by press pressure is placed at the inner corner to maintain optimal strength, and the vertical surface 64 Since the support piece 66 is formed to be long in the longitudinal direction on one side, it is possible to completely adhere to one side of the frame 50 to suppress fluidity during the process of assembling the support bracket 60 into the frame 50.

The shelf 70 is made of a rectangular flat body and is mounted and fixed on the support frame 60. That is, the fixing bolt (72a) is inserted into the through hole (71) formed at the edge of the four corners of the shelf (70) and fastened with the nut (72b) through the through hole (61a) of the support bracket (60).

Although not shown separately, it goes without saying that after appropriately arranging the shelf 70, a hanging rod can be mounted on the floor to use it as a hanger for hanging clothes.

In addition, the upper and lower fixing bars 80A and 80B are installed by inserting the left and right frames 50 into one set, respectively, at the upper and lower ends.

In the case of the upper fixing bar 80A, protruding bars 82a and 82b are formed at the lower ends of both sides of the body 81 and are inserted and assembled on the upper side of the frame 50 to fix the two frames 50. The lower fixing bar 80B has protruding bars 84a and 84b formed on both upper ends of the body 83 and can secure the two frames 50 by being inserted into the lower side of the frame 50 and assembled.

In addition, nuts 85 are embedded in the bottom surfaces of both sides of the lower fixing bar 80B, and an adjustment bolt 87 with an extension plate 86 is assembled through this nut 85 to finely adjust the height. It is desirable to do so, and in this case, it is also possible to conveniently move the shelf assembly by mounting an adjustment bolt with a small wheel.

In addition, it is also desirable to form reinforcing bars 88 in the bodies of the upper and lower fixing bars 80A and 80B including the binding members 55 to reduce material loss and maintain strength.

In the present invention with this configuration, it is desirable to first set the length of the frame 50 and the height of the shelf 70 according to the height to be placed. Accordingly, the height of the frame 50 is adjusted through the binding member 55, and then the upper and lower fixing bars 80A and 80B are assembled to the frame 50 forming one set.

Next, the two locking pieces 63a formed on the vertical surface 64 of the support bracket 60 are inserted and fixed into the two sets of perforated grooves 51 formed on one side of the frame 50. When these locking pieces (63a) are pushed and fitted into the narrow vertical groove (52b) through the wide horizontal groove (52a) constituting the perforated groove (51) of the frame (50), they are more flexible than before. It can be fixed more firmly without this.

In addition, in the process of assembling the support bracket 60 to the frame 50, the support piece 66 formed on one side of the vertical surface 64 is completely adhered to one side of the frame 50 to suppress fluidity. do.

In this way, with the upper and lower fixing bars 80A, 80B and the support bracket 60 mounted on each frame 50 forming a pair of two, the through hole 71a formed at the edge of the shelf 70 and The frame 50, the support bracket 60, and the shelf 70 are secured by inserting a fixing bolt (72a) through the through hole (61a) formed in the horizontal surface (62) of the support bracket (60) and then fastening it with a nut (72b). It is possible to reliably maintain a fixed state.

Therefore, the shelf 70 can be easily mounted after inserting and fixing the support brackets 60 into the perforated grooves 51 of the frame 50 according to the placement height of the shelf 70. Due to the self-weight of various items being mounted, the bonding force can be continuously exerted by receiving a certain load.

As described above, according to the shelf assembly for storing goods according to the present invention, two sets of perforated grooves are formed at predetermined intervals on one side of each pipe constituting the frame, so that rigidity can be maintained during the insertion of the support bracket. In addition, it is possible to reliably suppress the fluidity of the frame by using the upper and lower fixing bars.

In addition, the support piece formed on the support bracket can further strengthen the adhesion to the frame, and at the same time, the support bracket and the shelf can be easily fixed, and it is also possible to use it as a hanger for clothes by attaching a hanging rod.

In addition, the height of the frame can be freely adjusted using the binding member, and since the shelf is configured to be fixedly installed as a fastening element on the support bracket, assembly work can be performed much more easily than before and a stable structure can be achieved. .
