Description

[0001] The present invention relates to a column coupling structure,

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a column connection structure, and more particularly, to a column connection structure in which a column is easily assembled.

In recent years, DIY (Do It Yourself) furniture, which has reduced manufacturing assembly and distribution margins, has become very popular.

Basic furniture includes a desk, a table, a dresser and a shelf. These furniture usually consist of pillars supporting the top and top plates. Where the top plate and the column are usually assembled via bolt and nut connections.

However, the most uncomfortable thing about users of DIY furniture is that it takes too much time to assemble each part made of bolts and nuts.

For example, in the case of a column fixed to the floor and ceiling of a room, the entire length of the column is long, which makes it difficult to deliver. Therefore, the pillars fixed to the floor and the ceiling of the room are divided into three or four predetermined lengths, and then the divided pillars are delivered to the user. In this way, the bolts are provided at one end of the column divided into three or four, and the nut is provided at the other end, so that the user can assemble the separated columns through the bolt and nut coupling.

In other words, the user rotates the bolt-formed column or the column formed with the nut and joins the separated columns to each other.

However, in the process of assembling each part made of such a bolt and nut, the user has a lot of power, and it takes a lot of time, which makes it difficult to assemble the DIY furniture.

Therefore, there is a need for various studies on the posture bonding structure in which the user easily assembles DIY furniture with a small force.

That is, a gap may be formed between the outer diameter of the second assembling member 252 and the inner diameter of the second body member 240b.

The inner diameter of the second body member 240b is formed to be larger than the outer diameter of the second assembly member 252 to form a gap between the second assembly member 252 and the second body member 240b, The smooth movement of the threaded portion 250 in the space 241 and the elastic deformation of the first assembly member 251 when the male screw 130 is pressed can be smoothly performed. The details of this will be described later.

A second assembly hole 252h having a larger diameter than the first assembly hole 251h is formed in the second assembly member 252. [ The second assembly hole 252h is formed to be larger than the first assembly hole 251h so that the male thread 130 is screwed into the threaded portion 251h when the first column portion 100 and the second column portion 200 are engaged, 250 may be omitted. That is, the male screw 130 is screwed into only the first assembly member 251 having the female screw among the screw-engaging portions 250. Accordingly, the user can quickly and conveniently assemble the first post 100 and the second post 200. The first assembly hole 251h and the second assembly hole 252h form a through hole 255 of the threaded portion 250.

The connecting member 253 is configured to connect the second assembling members 252 separated by the slit portions 254 to each other. Here, the slit portion 254 is formed to split a plurality of second assembling members 252 in a cylindrical shape. The slit portion 254 is communicated with the through hole 255. The slit part 254 is formed not only in the second assembling member 252 but also in the first assembling member 251 so that the first assembling member 251 is also divided into the same shape as the second assembling member 252 .

As the slit portion 254 is formed in the threaded portion 250, the first and second assembly members 251 and 252 are elastically deformed within a predetermined elastic range, The size of the second assembly hole 251h and the size of the second assembly hole 252h can be adjusted.

The size of the first assembly hole 251h in which the female screw is formed before the elastic deformation is formed corresponds to the outer diameter of the male screw 130 so that the first assembly hole 251h with the female screw is screwed with the male screw 130, Lt; / RTI >

On the other hand, the cover portion 260 is coupled to the upper portion of the body portion 240. That is, the lid part 260 covers the upper part of the body part 240 having the opened upper part, and prevents the threaded part 250 provided in the accommodation space part 241 from being released to the outside of the body part 240 . The lid 260 is detachable from the body 240.

An opening hole 261 is formed at the center of the lid 260 so that the male screw 130 passing through the threaded portion 250 can be guided to the outside of the body 240 through the opening hole 261 have.

The first pillar 100 having the male screw 130 and the second pillar 200 having the female screw can be integrally assembled by screwing.

Here, the first column portion 100 and the second column portion 200 may have the same configuration. For example, the male thread 130 may be provided at one end of the column, and the female thread may be formed at the other end of the column. The plurality of pillars having the same configuration can be integrally coupled through the engagement of the male screw 130 and the female screw.

Also, the first column portion 100 and the second column portion 200 may be formed in different shapes. For example, a bottom fixing part (not shown) may be provided at one end of the first column part 100, and a male screw 130 may be provided at the other end of the first column part 100. A female screw may be formed at one end of the second post 200 and a ceiling fixture may be provided at the other end of the second post 200.

The first and second post portions 100 and 200 are not limited to a specific shape and may be integrally assembled through various combinations of the male thread 130 and the female thread.

It is needless to say that the column connection structure in the present invention is not necessarily limited to the column-type assembly structure, and may be applied to the connection between structures having various shapes.

FIG. 6 is an assembled view of a male screw inserted into a guide hole according to an embodiment of the present invention. FIG. 7 is an assembly example showing a screwing process of the first and second post portions according to an embodiment of the present invention. 6 and 7, the assembly process of the prefabricated column 1000 will be described in detail.

6 and 7, at the time of initial assembly of the first column 100 and the second column 200, the user inserts the male thread 130 of the first column 100 into the second column 200 In the guide hole 231 of the guide groove 231. As shown in Fig.

At this time, the male screw 130 can be inserted into the second pillar 200 without a separate screw connection. That is, in the process of inserting the male screw 130 into the guide hole 231 by a predetermined force or more, the first assembly hole 251h is opened by the pressing force of the male screw 130 and the male screw 130 is inserted do.

More specifically, when the user pushes the male screw 130 into the guide hole 231 with a predetermined force or more, the screw engagement portion 250 moves upward along the rotation preventing member 242 inserted into the slit portion 254 The first assembling member 251 can be opened by the slit portion 254 at the same time as it is moved.

In other words, when the first assembling member 251 having a truncated conical shape and brought into contact with the inside of the first body member 240a is moved upward along the rotation preventing member 242, the first assembling member 251 A gap may be formed between the outer side surface and the inner side surface of the body portion 240 forming the accommodation space portion 241. When the male screw 130 is inserted into the first assembly hole 251h with a predetermined force due to such an interval, the first assembly member 251 is moved in such a direction that the first assembly hole 251h is longer than the outer diameter of the male screw 130 So that the male screw 130 can be inserted through the threaded portion 250.

The outer diameter of the second assembly member 252 is smaller than the inner diameter of the second body member 240b so that when the male screw 130 is pushed into the guide hole 231 by a predetermined force or more, 250 can be smoothly moved upward along the anti-rotation member 242 inserted in the slit portion 254. [ In addition, when the first assembling member 251 is elastically deformed, the occurrence of the engagement between the first assembling member 251 deformed outward and the inner surface of the body 240 is minimized.

Accordingly, the user does not have to screw the entire length of the threaded male thread 130 in assembling the first and second posts 100 and 200. Thus, the user can easily assemble the first post 100 and the second post 200.

Referring to FIG. 7, the assembling process of the first post 100 and the second post 200 will be described. In a state where the predetermined force for inserting the male screw 130 into the guide hole 231 is released One or more of the first column portion 100 and the second column portion 200 may be rotated in the tightening direction and the first column portion 100 and the second column portion 200 may be assembled.

In this case, for example, the user may rotate the first column part 100 only in a state where the second column part 200 is fixed, and the first column part 100 may be rotated in the second column part 200 And the first column portion 100 and the second column portion 200 may be rotated together. At this time, when the user rotates at least one of the first column portion 100 and the second column portion 200, the user rotates the first screw hole 130 and the first assembly hole 251h in the tightening direction .

The rotation preventing member 242 is provided at a position where the threaded portion 250 provided inside the second column portion 200 in the process of screwing the first column portion 100 and the second column portion 200 through rotation Is prevented from rotating. Accordingly, the male screw 130 and the first assembly hole 251h can be screwed together.

When the first column portion 100 and the second column portion 200 are assembled through rotation, when the first column portion 100 and the second column portion 200 are moved upward in the initial assembling process of the first column portion 100 and the second column portion 200, The threadedly engaging portion 250 is moved downward along the rotation preventing member 242 and the outer side surface of the first assembling member 251 is entirely held in close contact with the inner side surface of the first body member 240a, The first pillar 100 and the second pillar 200 can be firmly coupled.

It should be understood, however, that the scope of the present invention is not limited by the scope of the present invention.
