Description

The present invention relates to a connecting member, and more specifically to a hierarchical shelf connecting member. The present invention also relates to a hierarchical shelf using the connecting member.

Hierarchical shelves and excellent storability are becoming more and more common in home life. Conventional hierarchical shelves have various styles and different structures, but the main body is composed of columns and shelves, and the difference between them is the connection method between the columns and the shelves. The current connection method is usually welding, screw connection, or the like. As technology advances and the level of user needs rises, and with the circumstances in which companies themselves consider production costs and transportation costs, removable engagement structures have been devised. This structure is assembled by providing connecting members at the four corners of the shelf board so as to be engaged with the columns of the hierarchical shelf via the connecting members. Therefore, it is convenient for transportation and easy for the user to assemble.

The engaging portion of the conventional connecting member has a semi-circular structure or an inner bottom polygonal structure. In use, the former has the disadvantage of unstable engagement because it is in contact with the column at only one point, and the latter has strict requirements for the press forming process and the mold, and the production cost is high. It turned out to be flawed.

The first object of the present invention is to provide a hierarchical shelf connecting member which has a rational structure, is easy to process, and has a good effect in use, in response to the above-mentioned drawbacks of the prior art.
Another object of the present invention is to provide a hierarchical shelf using the above connecting member.

The first technical solution of the present invention is realized as follows. A hierarchical shelf connecting member including a first main body, wherein the first main body is integrally molded with a connection portion connected to a shelf board and one end near the end of the shelf board in the connection portion, and is an external connection target. The positioning hook portion is composed of a positioning hook portion combined with the pillar body, and the positioning hook portion is composed of a guide portion located at an opening portion and a locking portion connected to the guide portion, and the locking portion is horizontal. The inner contour of the cross section in the direction is semi-elliptical.

The opening width of the guide portion is 0.5 to 2 mm larger than the diameter of the pillar to be connected, and the distance between the inner bottom portion of the locking portion and the pillar to be connected is 0.5 to 2 mm.

In the above-mentioned hierarchical shelf connecting member, the connecting portion is located at the bottom of the vertical plate portion to be connected and the extending portion at the lower end of the vertical plate portion is bent. It is composed of a support plate portion formed by being formed, and a mounting through hole is provided in the vertical plate portion. A screw is passed through the mounting through hole to be screwed to the shelf board to be connected, and a positioning hook is provided. When the portion is connected to the pillar body to be connected, both the vertical plate portion and the support plate portion support and position the shelf plate to be connected.

In the above-mentioned hierarchical shelf connecting member, the connecting portion includes a vertical plate portion suitable for the thickness of the shelf plate to be connected, a support plate portion formed by bending the extension portion at the lower end of the vertical plate portion, and a vertical portion. The extended portion at the upper end of the plate portion is composed of a pressing plate portion formed by bending, and the vertical plate portion is provided with a through hole for mounting, and a screw is passed through the through hole for mounting to be connected. When the positioning hook portion is connected to the shelf plate by screw and the positioning hook portion is connected to the pillar body to be connected, the vertical plate portion, the support plate portion, and the pressing plate portion all sandwich the edge of the shelf plate to be connected.

In the above-mentioned hierarchical shelf connecting member, the guide portion is composed of an arc-shaped curved portion integrally formed on the edge of the connecting portion and a guide portion provided at a distance from the arc-shaped curved portion.

The arcuate curved portion and the guide portion are integrally formed at both ends of the locking portion, and the positioning hook portion is formed by integrally pressing the extended portion at the edge of the connecting portion.

The present invention adopts the above structure and is designed so that the positioning hook portion is composed of a guide portion and a semi-elliptical locking portion. At the same time, by strictly limiting the important dimensional parameters of the columns to which the guide portion and the locking portion are connected, the manufacturing process and cost of the connecting member are the same as those of the conventional semi-circular structure, but the number of inner bottom portions is increased. Made to have the advantage of a polygonal structure.

By providing the guide portion, the width of the opening portion of the positioning hook portion is made appropriate, and the size of the locking portion is prevented from becoming too large. The reason is that in order to smoothly insert the support column to be connected into the positioning hook part, the opening needs to be slightly larger than the outer diameter of the support column to be connected, but the entire positioning hook part has an elliptical structure. In this case, it is necessary to increase the size of the entire positioning hook portion in order to secure the size of the opening, which reduces the locking effect.

The second technical solution of the present invention is realized as follows. It is a hierarchical shelf using the above-mentioned hierarchical shelf connecting member provided with a second main body, and the second main body is provided with four inverted U-shaped columns, and all four columns are in phase with each other. Along with being provided, two position-restricted connection rods are arranged facing each other at a vertical interval between the two columns facing each other, and the outer diameter of each position-restricted connection rod is a gap in the middle of the columns. And both ends of each position limiting connection rod are connected and fixed in a gap in the middle of the corresponding columns.

The position limiting connection rods located between each of the two pairs of facing columns have a one-to-one correspondence, and the positioning hooks of the four tier shelf connection members are the corresponding position limiting connection rods, respectively. It is located at the contact point between both ends and the support column, and the shelf board is combined and fixed to the connection portion of the four hierarchical shelf connecting members.

In the above hierarchical shelf, a female screw connection socket is provided at the lower end of the gap in the middle of each column, and if the lower end of the column comes into contact with the surface on which the hierarchical shelf is installed, the support leg is screwed to the female screw connection socket. It is connected.

In the above-mentioned hierarchical shelf, a first connection gap is formed between the position-restricted connection rod located at the lowermost end and the female screw connection socket, and the hierarchical shelf connecting members located at the four corners of the uppermost shelf board. A second connection gap is formed between the positioning hook portion of the above and the upper end bent portion of the column.

There are at least two of the second bodies, the two second bodies are detachably vertically connected by four connecting members, and the top and bottom of each connecting member are each first with screws. It is connected to the connection gap and the second connection gap.

In the above-mentioned hierarchical shelf, the connecting member is composed of two clamp plates having the same structure and provided facing each other, and an inverted U-shaped groove suitable for the upper end of a column is formed in the lower part of the clamp plate. The cross section of the inverted U-shaped groove is semi-circular.

A regular U-shaped groove that fits the lower end of the column is formed on the upper part of the clamp plate, and the clamp plate in the inverted U-shaped groove and the regular U-shaped groove has a second connection gap and a first, respectively. Position limiting protrusions that fit the connection gap are molded, and each position limiting protrusion is provided with a female screw hole, and the screw is combined with the female screw hole to connect the two clamp plates up and down. Two adjacent columns are clamped and fixed.

The present invention adopts the above structure and uses an inverted U-shaped strut to add another structure to the upper end of the strut as compared with the conventional structure in which two wires are arranged side by side. The upper end can be made smooth and cornerless, and this inverted U-shaped structure can overcome the drawback that the uppermost level shelf tends to come off upwards, and by devising improvements. It solves technical problems that could only be solved by conventional complicated processes.

The arc-shaped curved portion can easily guide the prism to be connected into the locking portion. The guide portion mainly serves to prevent the prism to be connected from slipping off during assembly. If the guide portion is omitted, the free end of the locking portion becomes considerably lower than the one end connected to the arcuate curved portion, which not only spoils the aesthetic appearance but also reduces the effect in assembly. As a matter of course, even if the guide part is omitted, it does not affect the overall stability after the connecting member is assembled, and only the smoothness when inserting the prism to be connected at the time of assembly is impaired. Is.

In the present embodiment, the connection portion 2 is located at the bottom of the vertical plate portion 2a suitable for the thickness of the shelf plate to be connected and the extended portion at the lower end of the vertical plate portion 2a is bent. It is composed of a support plate portion 2b formed by being formed. The vertical plate portion 2a is provided with a mounting through hole 2c, and a screw is passed through the mounting through hole 2c to be screw-connected to the shelf board to be connected. When the positioning hook portion 3 is connected to the column body to be connected, the vertical plate portion 2a and the support plate portion 2b both support and position the shelf plate to be connected.

By adopting such a structure, when the connection portion is connected to the shelf board to be connected, the upper end of the shelf board can be flattened, and foreign matter protrudes from the edge of the shelf board in terms of aesthetics and use. It does not impair the effect and does not interfere with the items on the shelves.

As shown in FIGS. 3 and 4, at the time of assembly, escape cutouts suitable for the positioning hook portions are provided at the four corners of the shelf plate, and then the vertical plate portion is brought into close contact with the side surface of the shelf plate and the support plate is provided. The portion may be brought into close contact with the bottom of the shelf board, and finally the connecting member may be tightened to the shelf board with screws.

Example 2
As shown in FIG. 5, the hierarchical shelf connecting member of the present invention has basically the same structure as that of the first embodiment, except that the connecting portion 2 is vertically adapted to the thickness of the shelf board to be connected. It is composed of a plate portion 2a, a support plate portion 2b formed by bending the extended portion at the lower end of the vertical plate portion 2a, and a pressing plate portion 2d formed by bending the extended portion at the upper end of the vertical plate portion 2a. The vertical plate portion 2a is provided with a mounting through hole 2c, and a screw is passed through the mounting through hole 2c to be screwed to the shelf plate to be connected, and the positioning hook portion 3 is a pillar to be connected. When connected to, the vertical plate portion 2a, the support plate portion 2b, and the pressing plate portion 2d all sandwich the edge of the shelf plate to be connected.

As compared with the first embodiment, since the connecting portion has a groove structure by providing the pressing plate portion at the top of the vertical plate portion, it is possible to connect to the shelf plate to be connected more stably. When it is necessary to lift the shelf board frequently, the shelf board and the connecting member can be stably connected by providing the pressing plate portion.
The method of connecting the connecting member and the shelf board is the same as that of the first embodiment.

Example 3
As shown in FIGS. 6 and 7, the hierarchical shelf using the above-mentioned hierarchical shelf connecting member of the present invention includes a second main body 6, and the second main body 6 has four inverted U-shaped columns 7. All four columns 7 are provided in the same phase, and two columns face each other, and a plurality of position limiting connection rods 8 are arranged at intervals in the vertical direction between the two columns 7 facing each other. The spacing and number of position limiting connection rods is determined by the number of shelves required and the article to be placed. The outer diameter of each position limiting connection rod 8 is the same as the gap in the middle of the columns 7, and both ends of each position limiting connection rod 8 are connected and fixed in the gap in the middle of the corresponding columns 7. ..

The position limiting connection rods 8 located between each of the two sets of two facing columns 7 have a one-to-one correspondence, and the positioning hooks 3 of the four hierarchical shelf connecting members have corresponding position restrictions, respectively. The shelf board 9 is combined and fixed to the connection portion 2 of the four hierarchical shelf connection members, which is located at the contact point between both ends of the connection rod 8 and the support column 7. The position-restricted connection rod not only serves to connect the stanchions on both sides to form the whole, but also serves to support the shelf board together with the stanchions.

By using an inverted U-shaped strut, the upper end is smooth and has no corners without adding another structure to the upper end of the strut, compared to the conventional structure in which two wires are arranged side by side. Moreover, this inverted U-shaped structure can overcome the drawback that the uppermost level shelf tends to come off upwards, and it can only be solved by the conventional complicated process by ingenious improvement. To solve technical problems. In the prior art, when using a structure in which two wires are arranged side by side, a horizontal rod is generally used to connect two columns on the same side in order to avoid exposing the upper end corner. It is necessary to add and weld, and it is necessary to polish both ends of the horizontal rod in the same way to avoid forming corners, which complicates the process. The present invention solves the above-mentioned problems simply and efficiently by simply bending one wire rod into a support column.
