Description

Multi-layer shelf assembly structure

The present invention relates to an assembly structure for assembling a shelf in a multi-layered structure, and more particularly, to a shelf assembly structure that can be easily assembled with a fitting structure and is not arbitrarily separated when the shelf is assembled in multiple layers.

Multi-layer shelves are used to display, store, and store items by stacking shelves vertically for efficient use of space.

The general assembly structure of the conventional multi-layer shelf is multi-layered by inserting pillars in the four corners of the shelf as disclosed in Korean Public Utility Model 20-1999-0000001 (1999.01.01) and registered utility model 20-0252494 (2001.10.18.). assembled and used.

However, the method of simply inserting the shelf and the column is inconvenient to use because the assembly part is easily removed, and there is a problem that the column is too easily separated when the shelf is lifted to move it. Therefore, if you hold the upper part of the shelf and lift it, it will come out more easily. Therefore, if you want to move or transport the shelf, you have the inconvenience of having to move or transport the items in storage.

In addition, these multi-layer shelves are usually made of plastic to provide a variety of shelf shapes while being able to mass-produce, but since plastics do not have a high hardness compared to other materials, when assembling in multi-layers, vibration occurs due to the clearance of the assembly parts. It is difficult to maintain a solid vertical state, and there are problems such as loosening or damage as the connection part is twisted when moving with a heavy object on it.

Therefore, as a way to solve the above problems, a method of assembling a shelf by making a plastic shelf and replacing only a column with a metal pipe is used. There are still issues with this.

And as another solution for assembling a plastic shelf in multiple layers, as in Republic of Korea Utility Model Registration No. 20-0194936 (June 26, 2000), a separate spacing tube and a fixing ring are assembled to support the column, or a patent As in No. 10-0776329 (2007.11.07.), a clip for fixing the column to the shelf is integrally formed, or as in Korean Patent No. 10-1899715 (2018.09.11.), with a fitting structure of a protrusion and an insertion groove. Assembling methods have been proposed, but these are all complicated in assembly methods or unsightly because the assembly parts are exposed to the outside. In terms of productivity, mold design is too complicated or assembly parts are increased, so there is a problem in product competitiveness due to an increase in manufacturing cost.

The present invention is to solve the above problems, and it is possible to simplify the assembly by allowing the shelf to be assembled in a multi-layer structure by a simple fitting method, and to provide a multi-layer shelf having a beautiful appearance without the assembly part being exposed to the outside at all. it was made to

In addition, despite the fact that all the assembly parts for assembling the shelf in a multi-layer structure are made of plastic, it maintains a vertically upright state, and even in a multi-layer assembly state, it prevents torsion or arbitrary separation due to external force and maintains a strong fixed state. made to do it

The present invention as a technical idea for achieving the above object is, in a multi-layer shelf assembly structure in which a shelf and a vertical assembly are assembled, a locking part is formed on the inner wall of a through hole penetrating vertically to engage the assembly part formed in the vertical assembly up and down The assembly is made while being fastened and fixed, and the assembly part is a first assembly part, which is first fastened in a hook method, and a second assembly part for fixing the fastening state of the first assembly part and preventing separation and separation. This makes assembly in a simple one-touch structure, and in the state where the shelf and the vertical assembly are assembled, the double assembly structure prevents arbitrary separation and maintains a solid assembly state.

According to the multi-layered shelf assembly structure of the present invention, it is very convenient to assemble because it can be easily inserted and assembled with one touch. In particular, it is very convenient to use because the assembly part does not come off even if the product is moved and transported in a filled state.

In addition, although the entire part is made of plastic, it is firmly fixed without any movement of the assembly part, and it is possible to firmly maintain a vertical state in a multi-layered state.

In addition, since the assembly part is not exposed to the outside at all, beautiful aesthetics and high-quality design can be provided. can be obtained

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

The present invention relates to a multi-layer shelf assembly structure in which the shelf 100 and the vertical assembly 200 are assembled as shown in FIGS. 1 and 2 , and the upper and lower parts of the fitting part 120 formed on the edge of the shelf 100 are mounted. Forms a through hole 122 penetrating into the through hole, and inserts the assembly part formed in the vertical assembly 200 in the through hole to engage and fasten it up and down so that the assembly is made, and the assembly part is the first assembly in which the primary fastening is made in a hook method. The assembly is made in a simple one-touch structure by sequential assembly of the part 220 and the second assembly part 240 to fix the fastening state of the first assembly part and prevent separation and separation, and the shelf 100 In the state in which the vertical assembly 200 and the vertical assembly 200 are assembled, arbitrary separation is prevented by the double assembly structure and a solid assembly state is maintained.

The shelf 100 is a structure that can display, store, and receive items, and may form a shelf in a plate-like structure, but more preferably, a side wall is formed along the rim of the bottom surface in a form in which the upper side is opened to provide a storage space. It may be configured as a basket-shaped shelf 100 constituting the shelf, and at this time, an opening may be formed on one side of the shelf so that an article can be easily inserted or taken out.

When the shelf 100 is formed in a basket shape, the flange 140 may be formed along the outer edge of the shelf, and the fitting part 120 may be formed on the flange 140, and the shelf ( When 100) is formed in a quadrangular shape, fitting portions 120 may be formed at the corners of the squares to insert the vertical assembly 200, respectively.

The vertical assembly 200 may include a pillar 202, a closing cap 204, and a leg rest 206, and each pillar 202, a closing cap 204, and a leg rest 206. The first assembly part 220 and the second assembly part 240 may be configured to be assembled by being fastened to engage with each other.

That is, the first assembly part 220 is formed on either one of the upper and lower sides on the column 202 that is stacked vertically between the shelf 100 and the shelf 100 to be spaced apart from each other, and the second assembly part ( 240), and the first assembly portion 220 or The second assembly part 240 may be formed so that it is engaged and fastened.

Therefore, when assembling the pillar 202 and the pillar 202, assembling the pillar 202 and the closing cap 204, or assembling the pillar 202 and the leg rest 206, The first and second assembly parts 220 and 240 are assembled by passing through the through hole 122 in 120 .

At this time, since the assembly is made by pre-assembling the first assembly part 220 and then fastening the second assembly part 240 , it is preferable that the assembly part to be fitted in the upward direction, that is, the upper side and the leg of the pillar 204 . The first assembly part 220 is formed on the upper side of the stand 206 , and the second assembly part 240 is formed on the lower side of the pillar 204 and the lower end of the closing cap 204 , thereby sequentially assembling from the lower part to the upper part. Since it is possible to assemble in a multi-layer structure while doing so, it is possible to assemble the leg rest 206 on the shelf 100, which is the lowest floor, first, put it on the floor, assemble the column, and assemble the shelf even though it is a multi-layer structure by sequential lamination assembly. that can be done easily.

In addition, as shown in FIG. 8, by arranging the pillars 202 over several layers and assembling the shelves 100 in multiple stages, the closing cap 204 and the leg rest 206 are assembled at the uppermost and lowermost ends, respectively. Various applications are possible because it can be used as a single layer by assembling a multi-layer shelf or by fastening only the closing cap 204 and the leg rest 206 to the shelf 100 without using the pillar 202 according to the needs of the user. Of course, it is possible to provide a beautiful aesthetic feeling because the assembly portion between the pillar 202 and the closing cap 204 and the leg rest 206 is not exposed to the outside at all.

Meanwhile, the assembly configuration in which the first and second assembly parts 220 and 240 are assembled to the fitting part 120 of the shelf 100 will be described in more detail as follows.

The shelf 100 has a fitting portion 120 formed on the above-described flange 140 , a through hole 122 is formed to penetrate vertically, and a locking portion 124 is formed on the inner wall of the through hole 122 . can be formed.

This locking part 124 is engaged with the hook 224 of the first assembly part 220 of the vertical assembly 200 to be described later to be fastened, and is formed to protrude from the inner wall or to be formed in a shape that is inserted into the inner wall. However, in order to form a single-mold structure that opens and closes up and down when forming a flange in a structure that integrally forms a storage space on the shelf 100, a locking part 124 is formed to protrude from the inner wall, and the locking part ( 124), the mold structure can be simplified by forming the parting line.

In the vertical assembly 200, the first assembly part 220 and the second assembly part 240 inserted to face each other into the upper and lower sides of the through hole 122 are engaged and assembled, and the first assembly part 220 ), the hook 224 is formed, and the primary fastening is made while being hooked and fixed to the locking part 124 of the shelf 100 .

And the second assembly portion 240 has a fitting protrusion 242 is formed so that the fitting protrusion 242 is inserted into the receiving portion 222 of the first assembly portion 220 so that the hook 224 hooking state does not flow. And, the auxiliary hook 244 is formed and caught at the lower end of the through hole 122 to prevent arbitrary separation of the second assembly part 240, so that the first assembly part 220 and the second assembly part 240 sequentially By assembling, the shelf and the vertical assembly have a double fastening structure, and arbitrary separation can be prevented.

At this time, the fitting part 120 is formed to protrude from both sides of the inner wall of the through hole 122 so that the engaging parts 124 face each other, and the first assembly part 220 is symmetrically formed on both sides of the receiving part 222 on the outside. When the hook 224 is formed and fixed to the locking part 124 while being elastically deformed to the inside and outside, the fitting protrusion 242 of the second assembly part 240 is attached to the inner wall of the hook as shown in FIG. 3 . Since the hook 224, which is inserted closely and symmetrically on both sides, is not elastically deformed to the inside, the fastening state of the hook 224 and the locking part 124 can be strengthened and it is possible to prevent arbitrarily falling out.

At this time, if the inner wall of the hook 224 formed symmetrically on both sides is formed with an inclined surface such that the width of the receiving portion 222 is gradually narrowed, the initial entry of the fitting protrusion 242 when the second assembly portion 240 is inserted. As the second assembly part 240 is inserted, it is assembled to reduce the play, and in a state in which the second assembly part 240 is completely inserted into the first assembly part 220, the hook 224 and the fitting protrusion ( 242), the assembly gap is minimized at the fitting part, and the assembly part is firm and can prevent shaking.

In addition, in the first assembling unit 220, the initial entry of the second assembling unit 240 is induced, and the second assembling unit 240 is completely inserted between the inner wall of the through hole 122 and the fitting protrusion 242. A guide 226 may be further formed to reduce the gap and minimize the play at the assembly site.

At this time, the guide 226 forms an inclined ramp 227 at the upper end, and the fitting protrusion 242 is inclined to the lower side in a form in which the thickness gradually becomes thinner. It can induce entry and allow it to fit without play.

That is, when the second assembly part 240 is inserted in a state in which the guide 226 is in close contact with the inner wall of one side of the through hole 122 , the fitting protrusion 242 is completely on the inner wall of the other side of the through hole 122 of the guide 226 . By making it close, it is possible to minimize the separation space at the assembly part.

At this time, in the second assembly portion 240, an auxiliary hook 244 is formed in the center of the lower end of the fitting protrusion 242. In order to sufficiently secure the elastic deformation range of the auxiliary hook 244, the fitting protrusion 242 is A rail portion 228 for guiding in a floating state without being completely in close contact with the outer surface of the guide 226 when inserted may be further formed.

Accordingly, when inserting, as well as in the case of separation using a separate tool, the auxiliary hook 244 is easily elastically deformed by hooking the tip of the tool, so that forced separation is facilitated.

That is, the shelf 100 allows the outer wall of the flange 140 to be formed to be spaced apart from the side wall and the fitting part 120 is formed in the spaced space, so that the shelf 100 can be simply molded into a single mold structure while the assembly part is moved to the outside. It can be prevented from being exposed, and when a tool such as a screwdriver is inserted into the exposed lower side of the flange 140 and the auxiliary hook 244 is tilted, the double fixing state is released and the second assembly part 240 can be separated. Then, separation is possible by releasing the hooked state of the first assembly part 220 through the exposed through hole 122 of the upper flange.

Therefore, in the case of assembling a multi-layer shelf, the shelf 100 and the vertical assembly 200 can be easily assembled by sequential one-touch fitting assembly. Even in this case, the assembled state does not come out arbitrarily, and when disassembly is necessary in an emergency, it is possible to separate using a tool or the like.

And the through hole 122 formed in the fitting part 120 is configured in a polygonal shape, and the hook 244 of the first assembly part 220 and the auxiliary hook 244 of the second assembly part 240 are perpendicular to each other. By making it fixed with the , it is possible to prevent shaking in all directions before, after, left, and right at the site where the first and second assembly parts 220 and 240 are assembled, and to maintain the shelf form stacked and assembled in multiple layers.

In addition, when the second assembly part 240 is inserted into the first assembly part 220 , the shelf 100 is positioned at the lower end of the fitting part 120 so that the auxiliary hook 244 is locked and fixed in place. The auxiliary hooking part 126 may be formed to correspond to the position of the auxiliary hook 244 of the second assembly part 240 , and since the auxiliary hook 224 is supported on the left and right sides of the auxiliary hooking part 126 , the lateral external force As the bearing capacity is further improved, it is possible to maintain a solid fixed state.
