[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a frame arranged so as to be in contact with the ground, a lateral rod surrounding the side surface of the chair pedestal, and a support plate provided below the lateral rod. A pedestal frame having: a first slide rail laterally disposed on both sides rear of the frame; a second slide rail disposed on both sides rear of the frame so as to be inclined forward and upward of the frame; The chair pedestal frame and the ear plate are arranged on the chair rest frame pivoted with screws, the rod connecting the chair pedestal frame and the chair rest frame, and the inside and the side rod of the first slide rail. A first slide wheel provided, a second slide wheel disposed inside the second slide rail and the support plate, and a transmission unit connected to the frame by a motor. By providing a driving device that moves and a telescopic unit that is connected to the driving device and the backrest frame of the chair, meshes with the screw helically, and has a worm that operates the screw by the transmission unit, convenience and comfort are improved. Performance can be improved.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but their configurations do not limit the structure of the present invention.

[Embodiment of the invention]

 FIG. 1 is a side view showing the structure of the reclining chair of the present invention. FIG. 2 is a side view showing the operation of the reclining chair according to the first embodiment of the present invention. FIG. 3 is a sectional view around the slide wheel according to the first embodiment of the present invention. 1 and 2, the reclining chair 1 of the present invention comprises a frame 20, a chair pedestal frame 30, a chair back frame 40, slide rails 21, 210, slide wheels 31, 310 and the like. The frame 20 is arranged so as to be in contact with the ground. A horizontal slide rail 21 and an inclined slide rail 210 are provided behind the frame 20 on both sides. The slide rail 210 in the tilt direction is tilted upward toward the front of the frame 20.

The chair pedestal frame 30 includes a lateral rod 32 surrounding the side surface of the chair pedestal, and a support plate 33 provided below the lateral rod 32. Slide wheels 31 and 310 are pivotally mounted at one end of the side rod 32 and one end of the support plate 33. As shown in FIG. 5, for example, one of the slide wheels 31 is fixed to the side rod 32 and the other is disposed inside the slide rail 21 so as to have a movable gap. Similarly, one of the slide wheels 310 is fixed to the side rod 32, and the other is disposed inside the slide rail 210 so as to have a movable gap.

The backrest frame 40 of the chair is assembled at a predetermined angle to the rear side of the chair pedestal frame 30. The connection between the chair base frame 30 and the chair back frame 40 will be described below with reference to FIG.

When the chair base frame 30 is moved forward in the direction of the arrow shown in FIG. 2, the backrest frame 40 of the chair falls down. At this time, the slide wheels 31 and 310 move along the slide rails 21 and 210, the slide wheel 31 moves forward of the slide rail 21, and the slide wheel 310 moves above the inclination of the slide rail 210. I do. Therefore, the reclining chair 1 can be inclined so that the user can lie down.

Next, the function of tilting the reclining chair of the present invention will be described in detail.

FIG. 4 is a perspective view showing the structure of the reclining chair according to the first embodiment of the present invention. FIG. 5 is an exploded perspective view showing the structure of the reclining chair according to the first embodiment of the present invention. In FIG. 4, a drive device 50 is provided on the frame 20, and the drive device 50 includes a motor 51, a transmission unit 52, and a telescopic unit 60. The telescopic unit 60 includes a worm 61 operated by the transmission unit 52 and a screw 62 connected to the frame 20. Since the worm 61 spirally meshes with the screw 62, the worm 61 is indirectly inserted into the screw 62 by the motor 51 moving the transmission unit 52. Accordingly, the worm 61 and the screw 62 are expanded and contracted to tilt the reclining chair 1.

As shown in FIG. 5, the backrest frame 40 of the chair has ear plates 41 formed at predetermined positions on both sides of the bottom end. The ear plate 41 is pivotally provided at a predetermined position with the lateral rod 32 by a screw 42. In addition, the rod 43 of the chair pedestal frame 30 is inserted in the direction of the arrow A and connected between the bottom ends of the backrest frames 40 of the chair. Therefore, even if the rod 43 moves in the direction of the arrow B, the chair pedestal frame 30 and the seat back frame 40 can be connected to each other around a predetermined position. It is also possible to connect using a plate instead of the rod 43.

FIG. 6 is a side view showing the structure of the reclining chair according to a modification of the first embodiment of the present invention. FIG. 7 is an exploded view showing the operation of the reclining chair in a modification of the first embodiment of the present invention. In the reclining chair shown in FIGS. 6 and 7, the footrest portion 34 of the chair pedestal frame 30 is different from the reclining chair of the first embodiment. The transmission unit 52 is connected to the frame 20, and the screw 62 is connected to the lower end of the backrest frame 40 of the chair. As shown in FIG. 7, when the worm 61 and the screw 62 expand and contract, the reclining chair 1 is inclined in the direction of the arrow.

As described above, the reclining chair 1 of the present invention drives the driving device 50 and the telescopic unit 60 to move the slide wheels 31 and 310 along the slide rails 21 and 210, thereby providing a chair pedestal frame. 30 and the chair back frame 40 can be inclined at a predetermined angle. Therefore, the user can comfortably lie on the lying chair 1, and the convenience of the lying chair 1 can be improved.

FIG. 8 is a perspective view showing the structure of the reclining chair according to the second embodiment of the present invention. The same components as those of the reclining chair shown in FIG. 8 and the reclining chair of the first embodiment are denoted by the same reference numerals and description thereof is omitted. In the reclining chair 2 shown in FIG. 8, the screw 62 is connected to the lower end of the chair pedestal frame 30. Further, the backrest frame 40 of the chair has a single rotation shaft fulcrum 70. Thus, the drive device 50 and the telescopic unit 60 are driven, and the chair pedestal frame 30 and the chair back frame 40 can be inclined at a predetermined angle about the rotation shaft fulcrum 70 as an axis. Therefore, the convenience and comfort of the reclining chair 2 of the present invention can be improved.

Note that the first slide rail corresponds to the slide rail 21, the second slide rail corresponds to the slide rail 210, the first slide wheel corresponds to the slide wheel 31, and the second slide wheel corresponds to the slide wheel 310.
