Description

Apparatus for combining assembly frame}

The present invention relates to a prefabricated frame fastening apparatus, and more particularly, to a prefabricated frame fastening apparatus for maintaining a rigid coupling force and to form a frame in a perpendicular direction by the sliding coupling.

In general, when assembling furniture or other forms using wood or other materials, coupling devices such as bolts, nuts, nails, and screws are used.

In addition, in addition to the various fastening devices are used to achieve a more robust coupling, the fastening is made by assembling using the coupling device by adding the fastening device in the state that the two materials are joined.

Although the fastening structure using the fastening device maintains a strong binding force, the fastening device undergoes a process of penetrating the inside of the material during the fastening process, and when the product is separated and reassembled, the fastening device is inserted into the penetrated part again. When not only when the bonding force is weakened, but also through a situation other than the penetrating portion to be bonded through the device of the material appears damaged parts appear aesthetic problems. Therefore, such a coupling structure is generally implemented only when reassembly is not executed.

On the other hand, in order to solve the disadvantage that the furniture is bulky and heavier in weight, it is often made prefabricated for storage and transportation, and the furniture is designed according to the preferences of consumers and the installation conditions of the furniture. As the furniture to be assembled is preferred, the fastening structure using the fastening device is not suitable for the prefabricated furniture. In particular, bookcases, shelves, and cabinets, which are relatively simple, are commonly purchased by consumers to purchase basic components and assemble them in a desired size and shape.

By the way, when the fastening structure is subjected to a strong leverage principle through the force of the side of the two materials in a situation that is connected at a right angle, the coupling device as well as the coupling device is deformed and the coupling portion may be broken.

In addition, the process of tightening and bolting in the joining process in the context of manufacturing the product is a problem that consumes a lot of manpower and time.

Accordingly, an object of the present invention is to solve the above problems of the prior art, and does not require a coupling device such as bolts and nails to form a frame in a right direction by simple sliding coupling and to maintain a firm coupling force. To provide a prefabricated frame fastening device.

Hereinafter, with reference to the accompanying drawings for the prefabricated frame fastening apparatus according to an embodiment of the present invention will be described in detail.

1 is a plan view of a fastening device of a prefabricated frame according to an embodiment of the present invention.

The prefabricated frame fastening device of the present invention is largely composed of a fastening device cover 30 which is fastened to the end of the fastening device 10 after the fastening device 10 and the frame 20 are fastened to the fastening device 10. .

As shown in FIG. 1, the fastening device 10 is configured such that the outer bent portion 11 and the inner bent portion 12 are formed to have a diameter of about 30 mm and a diameter of about 7 mm at regular intervals in the form of a quadrant. The inner and outer connecting wall pieces 13 connect the outer bent part 11 and the inner bent part 12 at both ends of each bent part 11 and 12, and maintain the gap between the bent parts 11 and 12 at about 18 mm. It is configured to be formed so that, the center of the outer bent portion 11, the inner bent portion 12 and both inner and outer connecting wall piece 13 is configured to form a through hole (14).

Both ends of the inner and outer connection wall pieces 13 are configured such that a first coupling support part 15 and a second coupling support part 16 are formed to extend in a length of about 32 mm from both ends, and both coupling support parts 15 and 16 are formed. Between the frame 20 is formed so that the frame fastening hole 18 having a width of about 18mm can be entered, the coupling support (15, 16) to each of the coupling support (15, 16) frame fastening When the insertion of the frame 20 in the form of protruding to the size of about 4mm in the direction of the ball 18 is configured to form a locking jaw (17) which serves to support the coupling of the frame 20, In the 15) is configured so that the locking jaw (17) is formed with a margin of about 4mm from the end to the inside, and the second coupling support (16) has a margin of about 14mm from the end to enter further The locking jaw 17 is configured to be formed.

Protrusions 19 are formed at regular intervals so that the frame 20 is smoothly inserted into the first coupling support 15 and the second coupling support 16 when the frame 20 is inserted and coupled, while maintaining a firm coupling force. It is configured to be.

Since the inner and outer connection wall pieces 13 are installed at both sides of the through hole 14 at right angles to each other, the first coupling support part 15 and the second coupling support part 16 are disposed at right angles as shown. It is configured to be installed on both sides, the locking step 17 is also configured to be installed on each side in the right angle direction, respectively, the projection 19 is also configured to be installed on each side in the right angle direction.

Here, the fastening device 10 is an outline 101 as shown in FIG. 2 to prevent the contents of the upper portion of the furniture from flowing down to the outside of the first coupling support portion 15 and to make use of the aesthetics of the fastening device 10. Is formed.

On the other hand, the frame 20 is formed so that the locking jaw insertion grooves 21 are deeply dug inward in each of the upper and lower parts, so that the space required for insertion into the locking jaw 17 when fastened to the fastening device 10 is configured. The locking jaw insertion groove 21 is a position of each locking jaw 17 when the frame 20 is coupled to the fastening device 10 so that the end of the frame 20 is inserted close to the inner and outer connection wall pieces 13. Corresponding to the upper and lower portions of the frame 20 is configured to correspond to.

As shown in FIG. 3, after the fastening device 10 and the frame 20 are fastened to each end of the fastening device 10 to prevent safety accidents due to human skin contact and finish the ends of the fastening device 10. The fastening device cover 30 to be coupled is coupled to the fastening device 10.

Figure 4 is a conceptual diagram for coupling the frame to the prefabricated frame fastening apparatus according to an embodiment of the present invention.

As shown in FIG. 4, the end of the frame 20 is positioned at one end of both ends of the fastening device 10, and the locking step 17 is inserted into the locking step insertion groove 21 of the frame 20. Partially inserted into the position and then coupled to the fastening device 10 by applying a little force to the other frame 20 is coupled to the other frame fastening hole 18 in the orthogonal direction of the fastening device 10. As a result, a rectangular frame assembly is formed.

As described above, the prefabricated frame fastening device according to the present invention does not require a coupling device such as bolts, nuts, screws, nails, etc. when assembling, thus maintaining a clean aesthetics and achieving a frame coupling by simple sliding operation. In addition, the locking jaw and the projection can achieve a more robust frame-to-frame coupling.
