BRIEF DESCRIPTION OF THE DRAWINGS

[0022] It is required to refer to the accompanying drawings exemplifying preferred embodiments of the present disclosure and the contents in the accompanying drawings to help sufficiently understand the present disclosure, the operational advantages of the present disclosure, and the objectives that are achieved by implementing the present disclosure.

[0023] The present disclosure will be described hereafter in detail by describing exemplary embodiments of the present disclosure with reference to the accompanying drawings. Like reference numerals given in the drawings indicate like components.

[0024] FIG. 1 is a view schematically showing an automatic sofa according to an embodiment of the present disclosure, FIG. 2 is a view schematically showing that a seat unit shown in FIG. 1 has moved forward, and FIG. 3 is a view schematically showing main parts of the embodiment.

[0025] FIG. 4 is a perspective view showing the inside of a seat actuator shown in FIG. 3, FIG. 5 is a view showing initial operation of the embodiment, and FIG. 6 is a view showing that the seat unit has fully moved forward as a following operation of FIG. 5.

[0026] As shown in the figures, an automatic sofa 1 according to the embodiment includes a main body 100 having a back support body 140, a seat actuator 200 disposed on the main body 100, and a seat unit 300 disposed on the main body 100 and connected to the seat actuator 200 to move.

[0027] The main body 100, which is a base structure of the present disclosure, as shown in FIG. 3, includes a horizontal body 110, a vertical body 120 disposed over the horizontal body 110, a base frame 130 disposed on the horizontal body 110 in the longitudinal direction of the horizontal body 110, and a back support body 140 disposed on the vertical body 120 and supporting the back of a user.

[0028] In the embodiment, the horizontal body 110 and the vertical body 120 may be made of one material selected from a wood material, a metal material, or plastic.

[0029] In the embodiment, the base frame body 130 may be made of one material selected from a wood material, a metal material, or plastic.

[0030] In the embodiment, as shown in FIG. 5, a rotation space 121 in which a rotary body 252 and a rotary arm 253 can be rotated may be formed inside the vertical body 120.

[0031] The seat actuator 200, as shown in FIG. 5, is disposed on the main body 100 and can move the seat unit 300 forward/backward with respect to the seat main body 100.

[0032] In the embodiment, the seat actuator 200 includes, as shown in FIG. 5, a driving motor 210 disposed on the main body 100, a sliding body 220 disposed on the main body 100 to be connected to the driving motor 210 and sliding forward/backward with respect to the main body 100, a seat coupling body 230 connected with the sliding body 220 to move with the sliding body 220 and coupling the seat unit 300 thereto, guide rails 240 disposed on the main body 100 and guiding slide movement of the sliding body 220, a rotary unit 250 coupled at a first side to the main body 100, coupled at a second side to the seat coupling body 230, and guiding movement of the seat coupling body 230, and a rail connection frame 260 connecting the pair of guide rails 240.

[0033] In the embodiment, when the driving motor 210 is operated, a screw shaft connected with the driving motor 210 is rotated and the sliding body 220 can be moved forward or backward with respect to the horizontal body 110 by the rotation force of the screw shaft.

[0034] In the embodiment, the seat coupling body 230 may be detachably bolted to the sliding body 220.

[0035] In the embodiment, the rotary unit 250, as shown in FIG. 5, includes a link member 251 coupled at a first side to the seat coupling body 230 and horizontally moving with the seat coupling body 230, a rotary body 252 coupled at a first side to the link member 251 and pushing the rear of the seat unit 300 by rotating when the link member 251 is moved, a rotary arm 253 coupled to a second side of the rotary body 252 and supporting the rotary body 252, and a coupler 254 rotatably coupling the rotary arm 253 to the main body 100.

[0036] Hereafter, operation of the rotary unit 250 is described.

[0037] When the driving motor 210 is operated and the sliding body 220 is moved to the position shown in FIG. 5, the seat coupling body 230 connected with the sliding body 220 is moved forward, whereby the seat unit 300 coupled to the seat coupling body 230 is also moved forward.

[0038] In this process, the link member 251 is horizontally moved forward, and as the link member 251 is moved forward, the rotary body 252 is rotated counterclockwise, as shown in FIG. 5, whereby the front of the rotary body 252 pushes the rear of the seat unit 300. When the rotary body 252 is rotated counterclockwise, the rotary arm 253 is also rotated counterclockwise, thereby being able to guide rotation of the rotary body 252.

[0039] In the embodiment, the rotary arm 253 may have a substantially L-shape, as shown in FIG. 5.

[0040] The seat unit 300, as shown in FIG. 5, includes a base seat 310 coupled on the seat coupling body 230 and provided as a part on which a user sits or lies, base supports 320 disposed on the front of the base seat 310 and supporting the base seat 310, and roller members 330 disposed at the lower portions of the base supports 320 and guiding movement of the base supports 320.

[0041] As described above, according to the embodiment, since the area of the seat on which a user sits automatically moves, it is possible to greatly improve convenience. Further, since the seat unit is stably moved by the rotary unit of the seat actuator, it is possible to provide a structurally stable automatic sofa.

[0042] The present disclosure is not limited to the embodiment described above and it is apparent to those skilled in the art that the present disclosure may be changed and modified in various ways without departing from the spirit and scope of the present disclosure. Accordingly, it should be noted that such changes and modifications are included in claims of the present disclosure.
