Description

Prefabricated shelf support structure

[0001] The present invention relates to an assembly-type shelf support structure, and more specifically, to an assembly-type shelf support structure that is easy to assemble and disassemble and is assembled so that items can be placed in multiple stages by attaching and detaching supports for each stage.

[0002]

[0003] Typically, modular shelves are multi-level shelves used for storing, displaying, or placing items. For example, they are used to display or store items in warehouses, supermarkets, marts, and other retail stores.

[0004] In the past, wire shelves were installed in multiple stages at a set interval on a support pipe, but since the fixtures had to be inserted from the top and moved to the fixed position, if an additional shelf was to be installed in addition to the installed shelf while the shelf was in use, all the fixtures fixing the shelf had to be loosened, the shelf had to be pulled out, and then the shelves had to be installed again sequentially, which was a hassle.

[0005] Korean Patent Publication No. 10-0483907 discloses a clamp for fastening a multi-level shelf, which divides the fastener into a first fastener and a second fastener and allows for connection between post bars, so that when multiple shelves are fastened, it is easy to replace shelves in the middle, add new shelves, or adjust the spacing between shelves. However, conventional shelf structures have a disadvantage in that it is difficult to change into various shapes because the joint member for connecting the intermediate crossbars mounted on the columns to each other in one or multiple rows is insufficient. In addition, since the intermediate crossbars are conventionally fastened to the joint member by screwing, it is difficult to easily separate the intermediate crossbars as needed, making disassembly and assembly difficult, which reduces workability.

[0006] Korean Patent Publication No. 10-2002-0089286 discloses a configuration in which a slot is formed in the longitudinal direction of a vertical member and a fitting piece is formed to be inserted and fitted into the slot on a horizontal member, thereby enabling assembly without bolt fastening. However, since the assembly position of the horizontal frame constituting the conventional shelf structure is fixed, there is an inconvenience in that it must be disassembled and then screwed again to move it to an appropriate position as needed. In addition, a bracket for mounting the horizontal frame of the conventional shelf structure to the vertical frame must be connected as a medium, but the conventional bracket must be assembled in the order of inserting the horizontal frame from top to bottom, making assembly and fixation complicated and taking a lot of time for disassembly.

[0007]

[0008] The present invention provides an assembly-type shelf support structure that can be assembled into a multi-layer structure by connecting a column that serves as a skeleton of a shelf and an intermediate crossbar that is connected transversely in a horizontal or vertical direction continuously, and that is provided with a joint member to facilitate connection of each part, thereby facilitating straight-line connection and inclined-direction connection and easy disassembly and assembly, thereby improving workability.

[0009] In addition, the present invention provides an assembly-type shelf support structure that improves the shape of a joint member so that a horizontal frame can be pushed in horizontally from the left and right directions to be combined, thereby simplifying the assembly or disassembly process and saving time.

[0110] Referring to FIGS. 13 and 14, the shelf support structure according to the third embodiment of the present invention has a different configuration of the second horizontal frame (142) and the crossbar (160) compared to the first embodiment of the present invention, and therefore, only the different configurations will be described below, and a detailed description of the same configurations and overlapping drawing symbols will be omitted.

[0111] A slide groove (422) may be formed in the longitudinal direction in the second horizontal frame (142). The slide groove (422) may be formed by being inserted into the interior of the second horizontal frame (142).

[0112] The crossbar (160) can be movably connected by having both ends inserted into the slide home (422). As a result, the crossbar (160) can be moved along the slide home (422), thereby enabling a change in position.

[0113]

[0114] FIG. 15 is an exemplary drawing showing a shelf support structure combined with a shelf according to an embodiment of the present invention, FIG. 16 is a plan view showing a shelf according to an embodiment of the present invention, and FIG. 17 is a cross-sectional view showing a first horizontal frame, a second horizontal frame, and a crossbar according to a third embodiment of the present invention.

[0115] Referring to FIGS. 15 to 17, the shelf support structure according to the third embodiment of the present invention has a different configuration of the horizontal support (140) and the crossbar (160) compared to the first embodiment of the present invention, and therefore, only the different configurations will be described below, and a detailed description of the same configurations with overlapping drawing reference numerals will be omitted.

[0116] The horizontal support (140) may include a first horizontal frame (141) and a second horizontal frame (142). The first horizontal frame (141) may include a left first horizontal frame (141L) and a right first horizontal frame (141R). The second horizontal frame (142) may include a left second horizontal frame (142L) and a right second horizontal frame (142R).

[0117] The first horizontal frame on the left (141L), the first horizontal frame on the right (141R), the second horizontal frame on the left (142L), and the second horizontal frame on the right (142R) may have a mounting groove (140a) formed in the longitudinal direction on one side of the upper portion to allow the end of the shelf (6) to be mounted, thereby forming a cross-section in the shape of the letter 'L'.

[0118] The cross-section of the crossbar (160) is formed in a 'convex' shape, so that a settling groove (161) can be formed on each side. Accordingly, the crossbar (160) and the first horizontal frame (141) on one side are arranged in abutment, and the end of the shelf (6) can be placed in the settling groove (410, 420, 430).

[0119] At this time, the shelf (6) may be at least one of a steel plate shelf (62), a mesh shelf (64), a mesh reinforced shelf (66), and a plywood shelf (68).

[0120] While the present invention has been described through examples above, these examples are merely intended to illustrate the spirit of the present invention and are not intended to be limiting. Those skilled in the art will appreciate that various modifications may be made to the above-described examples. The scope of the present invention is determined solely by interpretation of the appended claims.
