Description

Recliner sofa{RECLINER SOFA}

The present invention relates to a recliner sofa, and more specifically, to a recliner sofa in which the inclination of the seat portion, upper body rest portion, and leg rest portion is adjusted.

In general, sofas are furniture made to sit and relax, and have been handed down for centuries without much change in shape. However, recently, sofas used at home have been used in response to the increase in people's demands for rest, changes in the interior of living spaces, electronics, and family members. It is evolving accordingly.

This is a type of couch that evolved from a type of sofa that simply had the shape of a chair where you could sit with your legs bent and improved seating comfort by using more cushions than the chair. One part of the sofa mat was lengthened to allow people to sit or lie down with their legs stretched out. There are reclining sofas and recliner sofas in which the upper body of the sofa tilts backward, the seat tilts backward, and the leg rests tilt upward.

In particular, the recliner sofa solves the problems of existing sofas, for example, the upper body support is fixed to the seat and the tilt cannot be adjusted, so the comfort felt according to the user's body type or body condition cannot be increased. It was developed to overcome this.

Since the recliner sofa includes a mechanism operating part for adjusting the inclination of the seat part, the upper body support part, and the leg rest part, it is relatively expensive compared to a regular sofa.

The mechanism operating unit includes a motor that rotates forward and reverse, a reducer composed of a plurality of gears interlocked with the rotation axis of the motor, and a rod whose straight length is changed by being pulled out or drawn into the cylinder by the operation of the reducer. , and includes a plurality of link members that rotate by changing the straight length of the rod and adjust the inclination of the seat portion, the upper body support portion, and the leg rest portion.

Republic of Korea Patent Publication No. 10-1875884 (2018.07.06.) (hereinafter referred to as 'prior art') discloses a 'recliner sofa with adjustable headrest angle' equipped with a recliner device, which is the operating part of the mechanism. It is done.

However, since the lower structure of the recliner sofa according to the prior art is made of wood, the mechanism operating part made of steel cannot be firmly supported when installed directly on the lower structure. There was a cumbersome process problem in that a separate steel frame had to be installed to firmly support the mechanism operating part.

In addition, in the recliner sofa according to the prior art, since the lower structure is formed of a wooden body, when installing a plurality of sofas, the user himself has to perform the task of combining the lower structure with the lower structure of the neighboring sofa. There were also some difficult problems.

In addition, in the recliner sofa according to the prior art, in order to hide the mechanism operating part from being seen from the outside of the sofa, the lower structure is made of a wooden body, and the size of the lower structure is large, so the user can install the sofa by himself. There were also problems that made it difficult to do.

Republic of Korea Patent Publication No. 10-1875884 (2018.07.06.)

As described above, the recliner sofa 2 according to an embodiment of the present invention includes a mechanism operating part 400 that adjusts the inclination of the seat part 100, the upper body support part 200, and the leg rest part 300. Since the supporting lower steel frame 500 has a plurality of leg portions 511A, 512A, 523A, and 533A, the mechanism operating portion 400 can be directly attached to the lower steel frame 500 without the need to construct separate leg portions. Installation can simplify the assembly process.

In addition, in the recliner sofa 2 according to an embodiment of the present invention, the user can easily remove and reinstall the sofa on his own by holding and rotating the knob 711 of the bolt member 710 with his hand.

In addition, in the recliner sofa 2 according to an embodiment of the present invention, the user can easily install the backboard 600 by himself so that the complex internal structure is not visible from the outside after the sofa installation work is completed.

Those skilled in the art to which the present invention pertains will understand that the present invention can be implemented in other specific forms without changing its technical idea or essential features. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive. The scope of the present invention is indicated by the claims described below rather than the detailed description above, and all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts should be construed as being included in the scope of the present invention.
