Description

{Shelf for storage of goods}

The present invention relates to a technology related to an assembly shelf for displaying or loading various items, and more specifically, to a shelf structure for loading items configured so that a shelf mounted horizontally on a vertical metal frame can be easily assembled while the shelf can be maintained firmly without sagging.

Recently, there has been an increasing trend of using metal angles, which are relatively inexpensive and have excellent strength, rather than expensive materials such as raw wood, for general display cases or storage cabinets. Usually, shelves are arranged in multiple tiers between vertical and horizontal angles to easily display various types of items.

Most of these prefabricated metal angles are assembled using fasteners such as bolts or nuts between holes drilled at regular intervals in each frame. However, if the angle fastening is loose 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 always a risk of collapse.

Recently, technologies related to boltless fastening structures have been developed to enable quick and easy assembly without the need for separate fastening elements by punching or bending vertical and horizontal angles to be fastened to each other. However, there is a problem that the structure of shelves installed horizontally is weak, causing warping during long-term use.

With regard to such modular shelves, the technology disclosed in domestic utility model registration No. 0417642 focuses on the convenience of assembly and disassembly, but has the disadvantage that the assembly strength of the shelf itself is weak, making it susceptible to collapse or tipping over. In addition, since it is usually assembled with bolts and nuts, it is quite difficult to put your hand between the angles and fasten them.

Moreover, the complex structure of each frame makes manufacturing difficult and reduces productivity, requires skill in assembling and disassembling, and makes it difficult to install the shelf stably due to fluidity.

In addition, various boltless fastening methods are shown in domestic utility model registration No. 0228609, No. 0473792, etc., but the fastening force between the vertical and horizontal angles is structurally weak, so they do not adhere tightly and there is always a gap, which contains the problem that the assembled shelf cannot be used for a long period of time.

Utility Model Registration No. 0417642 (registered on May 24, 2006) - Wall-mounted assembly shelf. Utility Model Registration No. 0473792 (registered on July 23, 2014) - Boltless assembly angle structure.

The present invention is intended to solve the above-mentioned conventional problems, and the main purpose of the present invention is to provide a shelf structure for loading goods, which minimizes the components of vertical and horizontal frames, makes assembly and disassembly very easy, and can greatly improve production efficiency while ensuring price competitiveness.

In addition, the structural improvement of the shelf installed horizontally on the frame eliminates play and ensures sturdiness, and also prevents the shelf from sagging, thereby providing a shelf structure for loading items that can be used for a long period of time.

In order to achieve the above object, the present invention comprises a vertical frame arranged in parallel with a longitudinal interval, a horizontal frame fixedly installed with a interval on the vertical frame, and a shelf mounted and assembled on the horizontal frame, wherein a catch is formed on the upper rear surface of the shelf to prevent loaded items from slipping and falling off, and a cut-out groove is formed on each of the four corners of the upper surface so that the vertical frame can be fitted therein, and the vertical frame can be fixed with screws through holes in the stepped portions formed on both edges.

In addition, in the bottom surface of the shelf of the present invention, a pair of recessed grooves are formed horizontally at intervals, and reinforcing steel pieces are embedded to prevent sagging, and a pair of support pieces are formed so that they are configured to adhere to the inner surfaces of the horizontal frames on both sides when the shelf is assembled.

Due to the features described above, in the present invention, each forming operation for the vertical and horizontal frames and shelves is simple, and by minimizing the number of connecting parts, efficiency in terms of productivity can be greatly increased, and it can be supplied to users at a lower price than before.

In addition, compared to conventional shelf structures, it has the advantage of being able to significantly extend the service life as the assembly and disassembly work is generally simpler and structural stability can be secured.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the attached drawings, but the specific structures and functions thereof are only representative of one configuration example and are not limited to the embodiments described in this specification.

First, as a preferable example to which the present invention is applied, the core technology disclosed in registered utility model No. 0334180 will be extracted and explained, and after deriving problems therefrom, the composition and operational effects of the present invention will be described.

First, as shown in Fig. 1, the prefabricated angle display stand is basically composed of a vertical column (10) and a horizontal fixed beam (20). The columns (10) are each positioned at the corners of a square box shape, and the fixed beams (20) are each connected between these columns (10).

A flat-shaped support plate (30) is installed on the upper part of the fixed beam (20), and various necessary items are displayed on the upper part. The fixed beam (20) and the support plate (30) can be composed of several layers, and are represented as three layers in this drawing.

As shown in Fig. 2, a fixed beam (20) is configured to be detachable between two columns (10). A plurality of insertion grooves (12) are formed on the side of the column (10), and a ring-shaped hook (22) that can be attached and detached corresponding to the insertion grooves (12) is formed on both ends of the fixed beam (20).

In a state where the fixed beam (20) is connected to the column (10), the fixed beam (20) and the column (10) are connected by a connecting pin (40) so that the fixed beam (20) does not come off easily. A plurality of through holes (14) are formed on the side of the column (10), and through holes (24) are also formed at both ends of the fixed beam (20), and the connecting pin (40) is fastened into these through holes (14, 24). When the mold of the fixed beam (20) is made, the hook (22) is formed as one piece.

Figures 3 and 4 are drawings showing a modified example of a rectangular box-shaped assembly frame, which enables a plurality of rectangular box-shaped frames to be connected.

The above connecting beam (50) is attached to and detached from the pillar (10) with the fixed beam rotated 180 degrees to extend and assemble the frame.

In this case, since the horizontal beam is empty at the back of the connecting beam (50), the auxiliary beam (60) is mounted on the connecting beam (50), and a plurality of insertion grooves (56) are separately formed at both ends of the connecting beam (50) so that the auxiliary beam (60) can be mounted, and at the same time, hooks (62) mounted corresponding to the insertion grooves (56) are formed at each end of the auxiliary beam (60).

However, in the prior art as described above, since it is a structure in which hooks, penetration holes, insertion grooves, etc. are processed in a column or fixed beam, a separate work process or time is required, and since it is a structure in which a worker mounts a fixed beam on a column and then fixes it again using a connecting pin, etc., it causes the problem that workability is very poor.

Moreover, if the hook of the fixed beam is not inserted into the insertion groove of the column and is not firmly fixed, the fixed beam will not be forced into a fixed position and will move, which will reduce the fixing force. In addition, if the fixed beam is forcibly connected to the column, it will be very difficult to separate it again, which involves the unreasonable problem of being difficult.

The applicant of the present invention, taking into account various problems in the prior art, intends to propose a shelf structure for loading goods that enables easy assembly and disassembly of each frame and can be maintained more sturdily and stably, and this will be described in detail with reference to the attached drawings 5 to 8.

As shown in these drawings, the present invention is composed of a vertical frame (70) that is arranged in parallel with a spacing in the longitudinal direction, a horizontal frame (75) that is fixedly installed with a spacing on the vertical frame (70), and a shelf (80) that is mounted and assembled on the horizontal frame (75).

The above vertical frame (70) has an U-shaped cross section, and both ends of the horizontal frame (75) are fixed to form an H shape. The horizontal frames (75) can be installed at regular intervals along the length of the vertical frame (70).

In the case of the above horizontal frame (75), it is also possible to fix both ends to the vertical frame (70) in a conventional manner, such as by welding, to match the set height, and it can also be configured so that the height can be adjusted using an appropriate fastening means, such as a bracket (not shown).

The above shelf (80) is formed as a rectangular flat plate overall, and has a horizontal catch (81) formed on the rear of the upper surface to prevent loaded items from slipping and falling off, and cut grooves (82) are formed on the four corners so that each vertical frame (70) can be fitted into them.

In addition, a step portion (84) having a small hole (83a) is formed on both ends of the vertical direction of the shelf (80), so that it can be fastened to a screw hole (77) of the horizontal frame (75) using a screw (76) while mounted on the horizontal frame (75).

In addition, a pair of recessed grooves (85) are formed at intervals in the horizontal direction on the bottom surface of the shelf (80), and reinforcing steel pieces (86) are embedded in each of these recessed grooves (85), thereby preventing sagging due to load when loading goods.

Meanwhile, as shown in FIGS. 9a to 10, as another configuration example of the present invention, a pair of support pieces (87) are formed at a right angle to the reinforcing steel piece (86) installed on the bottom surface of the shelf (80) at an interval, so that when assembling the shelf (80), it is possible to configure it so that it is in close contact with the inner surface of the horizontal frames (75) on both sides.

The present invention, which is composed of such a configuration, can suppress fluidity by assembling the two sides of the shelf (80) on a horizontal frame (75) mounted on a vertical frame (70), thereby fitting the vertical frame (75) into the four corners of the shelf (80), and can be fastened to the screw hole (77) of the horizontal frame (75) by inserting a screw (76) through a small hole (83a) formed in the step portion (84) of the shelf (80).

At this time, since a reinforcing steel piece (86) is embedded in a pair of recessed grooves (85) formed on the bottom surface of the shelf (80), sagging due to load when loading goods can be effectively prevented, and when assembling the shelf (80), structural stability is achieved as the support pieces (87) are firmly attached to the inner surfaces of the horizontal frames (75) on both sides.

In this way, according to the shelf structure for loading goods according to the present invention, since each forming operation for the vertical and horizontal frames and shelves is simple and the number of connecting parts is minimized, it is possible to greatly increase efficiency in terms of productivity, and it is also possible to supply it to users at a lower price than before.

In addition, compared to conventional shelf structures, it has the advantage of being easier to assemble and disassemble overall, ensuring stability during assembly, and thus significantly extending the service life.

The technical task of the present invention is achieved by the technical configurations as described above, and although described based on limited examples and drawings, it is not limited thereto, and it is obvious that various modifications and variations are possible within the technical idea of the present invention and the scope of the claims to be described below by a person skilled in the art in the art.
