[0001] APPARATUS FOR FRAME CONNECTION [0002]

More particularly, the present invention relates to a frame connecting device which is composed of a tension bar and a fixing protrusion on three sides of a fitting portion, a bottom surface, left and right side surfaces of a connecting portion for connecting the frame vertically and horizontally continuously, And the fixing protrusion is formed on both sides of the frame so that the fixing protrusion is moved upward and downward due to the elastic force of the tension bar when the frame is coupled to the fitting portion of the coupling port, The frame can be coupled to the connector by one-touch, so that the frame and the connector can be easily coupled with each other. In addition, a seating groove is formed between the body and the fitting portion of the connector, So that the engaging force of the connecting portion and the frame can be increased. Relates to a one-touch frame is coupled to the connecting device to.

In general, the frame is coupled vertically and horizontally continuously to connect the connecting ends to both ends of the frame to produce a structure such as a table, a table, a cabinet, and the like.

7 and 8 are views showing a conventional coupling 100 and a frame 110 connected to the coupling 100 in a vertical and horizontal direction.

A coupling part 101 is formed on the outer surface of the body part 101 of the coupling hole 100 in a direction in which the frame 110 is coupled so that the frame 110 formed in a hollow shape can be continuously vertically and horizontally coupled, Bolt holes 102 are formed on the upper, lower, left, and right sides of the coupling portion 101.

Bolt holes 111 are formed on both sides of the frame 110 to correspond to the bolt holes 102 as shown in FIG.

The frame 110 is coupled to the coupling port 100 so that the coupling portion 101 of the coupling port 100 is inserted into the frame 110 having the bolt hole 111 as described above, 8, the frame 110 is coupled to the coupling portion 101 so as to be assembled and manufactured as shown in FIG.

However, a problem with the conventional frame connector is that when the frame 110 is coupled to the coupling portion 101 of the connector 100, the connector 100 and the frame 110 are fixedly coupled to each other using bolts and nuts as shown in FIG. Therefore, the efficiency of the operation is lowered, and the frame 110 is not coupled to the connector 100 in a single process.

As shown in FIG. 8, when the frame 110 is cut by a user's desired length, a cut piece 112 protruding inward is formed at the end of the frame 110. The cut piece 112 protrudes from the end of the frame 110 When the frame 110 is forcedly fitted to the outer surface of the coupling part 101 of the coupling 100 by the cutting piece 112, the cutting piece 112 is brought into close contact with the outer surface of the coupling part 101, Can not be brought into close contact with the outer surface of the coupling portion 101, so that the assembled structure is shaken upward, downward, leftward or rightward due to the pressure applied to the outside.

Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS. 1 to 6 attached hereto.

First of all, the present invention is designed so that a frame 40 formed in a hollow shape and a connection port 1 for continuously and vertically and horizontally joining the frame 40 can be coupled with one touch.

In order to vertically and horizontally connect the frame 40 continuously, the body portion 10 of the connector 1 is formed with a fitting portion 11 in a direction in which the frame 40 is coupled.

At this time, the end of the fitting part 11 is tapered so that the fitting part 11 of the fitting part 1 can be easily coupled to the inside of the frame 40 formed in a hollow shape.

The fixing part 20 is symmetrically arranged as shown in FIG. 1 so that the frame 40 can be coupled to the upper, lower, left, and right sides of the fitting part 11 protruding from the body 10, .

The fixing part 20 formed on the fitting part 11 cuts three sides to form a tension bar 21. At the end of the tension bar 21 the frame 40 is fitted to the outer surface of the fitting part 11 3 (b) and 3 (c) by the elastic force of the tension bar 21 at the time of coupling.

As shown in FIG. 1, fixing holes 41 are formed on both sides of the frame 40 in correspondence with the fixing protrusions 22 so that the fixing protrusions 22, which are moved up and down by the elastic force of the tension bar 21, 3 (b) and 3 (c), when the fitting portion 11 is engaged with the inside of the frame 40, the fixing protrusion 22 is elastically deformed by the elastic force of the tension bar 21 The frame 40 can be coupled to the connector 20 by one touch because the connector 40 is coupled to the fixing hole 41 formed in the frame 40 while being moved upward and downward.

At this time, the fixing protrusion 22 protruding from the end of the tension bar 21 protrudes in the form of a dome so that the frame 40 is naturally coupled when it is engaged with the fitting portion 11 of the coupling 1, It is possible to prevent the frame 40 coupled to the fitting portion 11 of the fitting 1 from falling back from the fitting 1. [

3 (a) to 3 (c), the fixing portion 20 having the fixing protrusions 22 is formed in the fitting portion 11 of the connector 1 inserted into the inner end of the frame 40 And fixing holes 41 are formed on both sides of the frame 40 so as to correspond to the fixing protrusions 22. When the frame 40 is coupled to the outer surface of the fitting portion 11, 3 (b), it is coupled to the fixing hole 41 of the frame 40 as shown in FIG. 3 (c), while being moved upward and downward by the elasticity of the tension bar 21, It is possible to combine the frame 40 with one-touch.

At this time, a fixed end 23 is vertically formed at one end of the fixing protrusion 22 as shown in FIG. 5 to prevent the frame 40 from being easily detached in a direction opposite to the direction in which the frame 40 is coupled.

5, when the frame 40 is engaged with the fitting portion 11 as shown in Figs. 6 (b) and 6 (c), the fixing projections 23 are fixed Since the fixed end 23 of the projection 22 is in close contact with the inside of the fixing hole 41 of the frame 40, the frame 40 can be easily detached from the frame 40, It is possible to expect an effect that can be prevented.

The body 10 and the fitting portion 11 of the connection port 1 are connected to each other so that the cutter piece 50 protruding to the inside of the frame 40 is inserted at the same time as the frame 40 is cut by a desired length. The mounting grooves 30 are formed between the boundaries as shown in Fig.

The mounting groove 30 is formed between the body 10 of the connector 1 and the interface of the fitting portion 11 so that the cutting piece 50 formed at the end of the frame 40 is inserted inwardly 3 (c), since the frame 40 is tightly coupled to the outer surface of the fitting portion 11, the coupling force between the coupling 1 and the frame 40 can be increased, It is possible to expect an effect that the work speed can be increased because there is no need to remove the work 50.

4 (a) to 4 (c) show another embodiment of the connector 1. FIGS. 4 (a) and 4 (b) , And FIG. 4 (c) shows a structure in which the frame 40 can be combined with a '+' shape.

By forming the connector 1 as shown in FIGS. 4A to 4C, it is possible to expect the effect that the user can easily manufacture the structure with a desired size.
