In addition, the present invention has a purpose to provide a fastening device having a strong fastening state of the sofa even using the sofa and a sofa using the same.

According to an aspect of the present invention for achieving the above object, a fastening device that is attached to the main frame and the auxiliary frame of the detachable furniture, respectively, to be detachable, so that the tapered shape from the upper side of the front side to the lower side, A first fastening portion formed to have a tapered shape from the back; And a second fastening part having an accommodating groove formed on the front surface of the first fastening part to be slidably inserted into the first fastening part.

Preferably, the cross section in the transverse direction of the first fastening portion is characterized in that the trapezoid or arc shape.

The first fastening part and the second fastening part may be processed by die casting.

In addition, the first fastening portion and the second fastening portion is characterized in that the fastening hole is formed so that the bolt is inserted and fastened.

In addition, the present invention, in the furniture comprising a main frame and a back frame is mounted on the seat plate and armrests are mounted in the vertical direction on the left and right sides of the main frame, respectively, tapered from the upper side of the front side to the lower side A first fastening portion formed into a shape and tapered from the front surface to the back surface; And a second fastening part mounted to the auxiliary frame in a vertical direction, the second fastening part having an accommodating groove on the front surface of the first fastening part to be slidably inserted into the first fastening part.

Therefore, the main fastening unit and the second fastening unit can be used to easily combine or separate the main frame and auxiliary frame, such as a sofa and a bed.

In addition, the fastening device of the furniture is composed of the first fastening portion and the second fastening portion of the simple form has the advantage that can be easily manufactured through the die-casting process.

In addition, the entire side of the first fastening portion is inserted and fixed to the second fastening portion, so that the main frame and the auxiliary frame are firmly coupled.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the fastening device and furniture using the same according to the present invention.

2 is an exploded perspective view schematically illustrating a fastening device and a sofa using the same according to the present invention, and FIG. 3 is an enlarged view of the first fastening part and the second fastening part of FIG. 2, as shown in FIG. 2. Shows the combined state of the sofa frame with the cushion and the shell removed.

First, a seat plate (see FIG. 1) is mounted on an upper side of the main frame 100, armrests (see FIG. 1) are mounted on both sides of the main frame 100, and fastened at the rear of the main frame 100. The auxiliary frame 200 is equipped with a backrest (see FIG. 1).

At this time, the left and right sides of the main frame 100, that is, the inner side of the left and right sides of the main frame 100 to which the armrest is mounted facing each other and the first fastening portion 300 is mounted, the auxiliary frame 200 The second fastening parts 400 are mounted at left and right sides of the main frame 100 at positions corresponding to the first fastening parts 300.

The first fastening portion 300 is mounted in the vertical direction on the left and right sides of the main frame 100, the upper portion is narrow and the lower portion is formed in a tapered shape from the front upper side to the lower side, the second fastening portion 400 Is mounted on the left and right sides of the auxiliary frame 200, that is, the position corresponding to the first fastening portion 300 mounted on the main frame 100, the receiving groove 410 of the same shape as the first fastening portion 300 That is, the upper portion is narrow and the lower portion is formed with a tapered shape receiving groove 410 from the upper side to the lower side.

Specifically, the first fastening portion 300 has a transverse cross section having a trapezoidal shape, the width of which extends from the upper surface 310 to the lower surface 320 increases, and the width thereof increases from the front surface 340 to the rear surface 330. The narrow angle is formed to be inclined at an angle, as shown in Figure 4, when viewed from the bottom or the upper surface it can be seen that the cross-sectional shape of the trapezoidal shape.

In addition, the second fastening portion 400 has a receiving groove 410 having the same shape as the first fastening portion 300 on the front surface thereof, as in the first fastening portion 300 toward the top to the bottom It is formed to be inclined at an angle so as to widen its width. As shown in FIG. 4, it can be seen that the cross-sectional shape has a trapezoidal shape when viewed from the bottom or upper surface side. On the other hand, the cross-sectional shape of the first fastening portion 300 may be not only trapezoidal, but also arc-shaped.

Two or three fastening holes 350 and 450 are formed in the accommodation grooves 410 formed in the first fastening part 300 and the second fastening part 400. This is for fastening the first fastening part 300 and the second fastening part 400 to the main frame 100 and the auxiliary frame 200 with bolts, respectively.

On the other hand, the first fastening portion 300 and the second fastening portion 400 as described above is preferably processed by using die casting in order to increase the precision when fastening.

Hereinafter, with reference to the drawings will be described the action and effects of the fastening device configured as described above and the sofa using the same.

First, the first fastening unit 300 is fastened and mounted on the left and right sides of the main frame 100 by bolts, respectively, and the left and right sides of the auxiliary frame 200 correspond to the first fastening unit 300 respectively. Fasten the second fastening portion 400 to the position by bolts.
