Description

Synchro tilt type chair {SYNC. TILT TYPE CHAIR}

The present invention relates to a synchro-tilt-type chair, and more particularly, to a synchro-tilt-type chair having a firm and reliable tilt structure and improved aesthetics by combining the tilt part, the back part, and the coupling bar in combination.

Recently, chairs have been designed to have a variety of functions and designs beyond the concept of a person sitting. In particular, with regard to comfort, recent chairs are typically configured such that the backrest or seat plate is tilted when the user sits so that the user can feel comfortable.

As the tilting means, which is a means for implementing such tilting, is provided, the user's convenience of the chair can be improved. However, since the load burden due to frequent tilting is concentrated at the portion where the tilting means and the back of the chair are coupled, durability and stability of the chair are increased. Securing can be a problem.

In addition, the tilt part may be made of a relatively complicated structural device to secure aesthetics of the lower part of the chair may also be a problem.

Can be combined together. Thus, a more structurally stable bonding structure can be achieved.

In addition, by maintaining the structure of the synchro-tilt-type chair (1) can be achieved by a more secure coupling structure by fixing the coupling bar 300 of a simple structure, while having an aesthetically excellent lower structure, the coupling structure is achieved The production cost required to do so can be reduced.

Hereinafter, the coupling relationship between the coupling bar 300 and the armrest part 400 will be described with reference to FIG. 3.

The armrest unit 400 is disposed between the armrest body 410 and the armrest body 410 and the coupling bar 300 which is configured to be bent downwardly and has a seating portion to seat the user's arm. 410 and the coupling bar 300 may include a connection member 420 to be connected smoothly.

One end of the armrest body 410 is formed with a first inserting portion 412 so that the connection member 420 can be inserted. The first insertion part 412 may be formed to have an inclined surface so that the connection member 420 can be stably inserted corresponding to the shape of the outer surface of the connection member 420 which will be described later. As shown in FIG. 3, the inclined surface has a shape in which the cross-sectional area is extended toward the end direction of the armrest part 400 in which the first insertion part 412 is formed, and the cross-sectional area is reduced in the inner direction, for example, to have a trapezoidal shape. Can be.

The connection member 420 may be inserted into the first inserting portion 412, and a second inserting portion 426 may be formed so that one end of the coupling bar 300 may be inserted. As described above, the outer shape of the connection member 420 may have a shape corresponding to the inner circumferential surface of the first insertion part 412 and thus may have an inclined surface such as a trapezoid. In addition, the second insertion portion 426 has a shape corresponding to one end of the coupling bar 300, and thus may have a shape such as a rectangle.

On the other hand, grooves 422 extending in the longitudinal direction are formed on both side surfaces of the connecting member 420. Preferably, the connecting member 420 is made of a material having a predetermined elasticity such as plastic and configured to be deformable within a predetermined range, and the distance between the upper and lower surfaces of the connecting member 422 is adjusted based on the groove 422. The size of the vertical direction of the 420 may be adjusted. Therefore, the connection member 420 may be seated and inserted into the first inserting portion 412.

Meanwhile, a first fixing hole 414 is formed in the armrest body 410, a second fixing hole 424 is formed in the connection member 420, and a third fixing hole 322 is formed in the coupling bar 300. The first to third fixing holes 414, 424, and 322 may be disposed to overlap each other.

In addition, since the groove 422 is formed at the side of the connection member 420, injection molding is easy, and thus, process efficiency and economic efficiency may be further improved.

In addition, as the connecting member 420 is disposed between the armrest body 410 and the coupling bar 300, the allowable range of the process margin is greater than the case in which the armrest body 410 is directly coupled to the coupling bar 300. And coupling between the coupling bar 300 can be more stably achieved.

In addition, the connection between the coupling bar 300 and the armrest body 410 is made by using the connection member 420 having a size corresponding to the insertion portion with respect to the armrest body 410 having an insertion portion of any size. As such, the replacement of the armrest portion 400 is easily achieved and excellent versatility can be achieved.
