Description

  The present invention relates to a connecting structure of a lower tube body and an upper tube body of a fixed column for an assembly furniture. More specifically, 2-4 pieces are cut out on a vertical line of an insertion portion formed on an upper portion of a lower tube body. Connection of lower tube and upper tube of fixed post for assembling furniture which can form a long hole selectively and is extended to the outside of the side surface by this cut long hole, and can prevent left and right shaking when connecting the upper tube Concerning structure.

Conventionally, assembling furniture is widely used in order to efficiently use a narrow space of a general household.
These prefabricated furnitures are used for the purpose of storing clothes and various life tools by integrally connecting a shelf, a basket or a hook to a fixed column.
As illustrated in FIG. 5, the fixed support 50 which is the most important configuration in the assembly-type furniture is configured as a structure for connecting the lower tubular body 20 and the upper tubular body 30 in order to facilitate packing and transportation. Is done.
The coupling of the lower tubular body 20 and the upper tubular body 30 constituting the fixed support 50 uses the small-diameter insertion portion 15 formed on the upper portion of the lower tubular body 20, which is formed in the upper tubular body 30. The diameter of the hollow portion 25 is the same as the inner diameter.
This is used by connecting the insertion portion 15 to the lower portion of the upper tubular body 30, and in this, the outer diameter of the insertion portion 15 and the inner diameter of the hollow portion 25 constituting the upper tubular body 30 are the same diameter. Therefore, it not only sways to the left and right, but also easily separates, causing a considerable hindrance to its use.

  The present invention is proposed in consideration of the above-mentioned various problems. The present invention is designed to sway left and right and easily separate when connecting the upper pipe to the lower pipe constituting the fixed support. The main object of the present invention is to provide a connecting structure for a lower tube body and an upper tube body of a fixed post for an assembled furniture that can prevent the above-described problem.

In order to achieve the above object, the overall configuration of the present invention consists of a lower tubular body having a small-diameter insertion portion added to the upper portion, and a cylindrical fixing comprising an upper tubular body integrally coupled to the insertion portion. In the support column, the insertion portion is formed as a structure in which a long hole is cut out on a vertical line.
In particular, the cut long holes formed in the insertion portion mainly have a structure in which 2 to 4 are selectively formed.

  According to the first and second aspects of the present invention, in the cylindrical fixed column composed of the lower tube body having a small-diameter insertion portion added to the upper portion and the upper tube body integrally coupled to the insertion portion, the insertion By forming a slotted hole on the vertical line of the insertion part by forming a slotted hole on the vertical line (for example, a structure in which 2 to 4 are selectively formed) , The outer surface of the cut long hole expands to the outside, the diameter expands, and it is connected by forcibly inserting it into the upper tube, so that it can be easily separated as well as the left and right shaking of the upper tube Therefore, it is possible to provide a connection structure for the lower tube body and the upper tube body of the fixed post for fixed furniture for assembly.

FIG. 1A is a perspective view illustrating a configuration state of the present invention. FIG. 1B is a perspective view illustrating the configuration state of the present invention. FIG. 1C is a perspective view illustrating the configuration state of the present invention. FIG. 2 is a longitudinal sectional view of the present invention. FIG. 3 is a plan view of the present invention. FIG. 4 is an enlarged cross-sectional view illustrating a state in which the lower tube body and the upper tube body are coupled. FIG. 5 is a front view illustrating the structure of a conventional fixed column.

  The present invention relates to a lower column and an upper tube of a fixed column for an assembly furniture that can prevent left and right shaking and easy separation when the upper tube is coupled to the lower tube constituting the fixed column. The purpose of providing and providing a connecting structure is as follows.In the cylindrical fixed column composed of a lower tube body having a small-diameter insertion portion added to the upper portion and an upper tube body integrally coupled to the insertion portion, the insertion This is realized by a structure characterized by comprising a structure in which a long hole is cut out on a vertical line in the part.

  Hereinafter, a connection structure of a lower tube body and an upper tube body of an assembly furniture fixed column according to an embodiment of the present invention will be described in detail with reference to the drawings.

  1A, 1B, and 1C are perspective views illustrating the configuration of the present invention, FIG. 2 is a longitudinal sectional view of the present invention, FIG. 3 is a plan view of the present invention, and FIG. It is an expanded sectional view which illustrated the state where the tube and the upper tube were combined.

As illustrated in the drawings, the present invention is a modification of the structure of the fixed support 50 widely used in assembling furniture.
In other words, it was proposed in consideration of the material characteristics of the steel pipe constituting the fixed support 50, and it was focused on the point that due to the material characteristics, a part of the steel pipe was cut out to cause expansion to the outside due to elasticity, and the diameter increased. .
That is, as illustrated in FIGS. 1A, 1 </ b> B, and 1 </ b> C, 2-4 on the vertical line of the small-diameter insertion portion 15 formed on the upper portion of the lower tubular body 20 constituting the fixed support 50. The cut long hole 14 has a structure in which the width of the cut long hole 14 is 2 to 3 mm.
Thus, the inner side surface 14a expands outward by forming the cut long hole 14 having a narrow width.

  By expanding in this way, the inner side surface 14a formed between the cut long holes 14 expands outward and expands larger than the diameter of the insertion portion 15 as shown in FIG.

  In addition, the inner side surface 14a formed between the cut long holes 14 constituting the insertion portion 15 is not only expanded in diameter, but also when a physical force is applied to the outer side surface, the inner side surface 14a attempts to restore the original position. It will have the added elasticity.

  By connecting this with the hollow portion 25 formed in the upper tubular body 30, the diameter of the insertion portion 15 expands at the time of this connection, and the diameter is slightly larger than the diameter of the hollow portion 25. A combination is established as a form.

When the upper tubular body 30 is coupled to the outer side surface of the insertion portion 15 in this way, an expansion force acts on the outside by the cut long hole 14 formed on the vertical line of the insertion portion 15.
By such an expansion force, the outer surface of the insertion portion 15 and the inner surface of the hollow portion 25 are tightly joined, so that the upper tubular body 30 can be prevented from shaking left and right, and the lower tubular body 20 to the upper tubular body 30 can be prevented. However, it is possible to prevent the disadvantage of being easily separated.

  The present invention can be implemented not only by the structure described in the embodiment of the present invention as described above, but also through other devices that realize functions corresponding to the configuration of the embodiment of the present invention. Such a configuration can be easily realized by the expert in the technical field to which the present invention belongs from the description of the embodiment described above, and it is obvious that this is also within the scope of the right of the present invention. It is.

  The present invention can be widely applied to a similar support column as well as the above-described fixed column for an assembled furniture.
