Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reclining chair having a dining chair and a relaxing chair that can be easily lowered by reversing the seat and can be converted into a reclining shape.

[0002]

[Prior art]

 Conventionally, as a reclining chair, a gear for adjusting the backrest angle is incorporated in the connecting portion between the seat portion and the backrest member, and a lever provided at the end of the reclining chair releases the gear that meshes with the backrest angle. Can be freely changed, or the seat and backrest members can be used as a folding chair with a double structure at all times by connecting parts such as hinges, and when used as a reclining chair, they can be reclined by expanding them. There is a method that can be used as a chair.

[0003]

[Problems to be solved by the device]

 However, in each of the above-mentioned methods, the gear used for adjusting the backrest angle is always worn and damaged by the load applied, or the gear is bulky as a whole. There is a problem that the weight is large and it takes time to carry, and because of ergonomics, the backrest must be tilted and the seat part must be lowered, and the tilting must be done. There is no one with. Also, since the backrest is tilted backward, it cannot be in contact with the wall of the room. Especially in the case of a chair that has both a dining chair and a chair for relaxation, ergonomically, in order to increase relaxation, the height of the seat, the angle of the seat, the inclination of the backrest and the length of the backrest may change. It is a necessary condition, and there is a challenge in changing the seat height, especially in terms of increasing relaxation. Therefore, in order to solve the above problems, the present invention aims to provide a reclining chair in which the height of the seat also changes when it is converted into a reclining shape.

[0004]

[Means for Solving the Problems]

 The above object of the present invention can be achieved by a chair having the following configuration. In other words, the gist is that a reversible seat part consisting of a double structure consisting of a backrest and an upper seat part and a lower seat part with its base end side connected and supported between leg parts that are erected at regular intervals. , The base portion front side of the backrest / upper seat portion and the leg portion are connected and pivoted, and the middle portion of the lower seat portion and the leg portion below the lower seat portion are connected and pivoted to each other by a connecting rod. Furthermore, the backrest part is attached to the rear of the leg part, and the reclining chair has a variable seat height. Further, the auxiliary leg portion is extended at the tip of the lower seat portion, or the leg portion is provided with a stopper portion for locking the lower seat portion after the reclining conversion.

[0005]

[Action]

 As shown in FIG. 3 and FIG. 6, the reclining chair of the present invention reverses the backrest / upper seat 4 in the direction of arrow A in the figure, so that the lower seat 5 moves forward while the seat height and seat angle are adjusted. The angle of inclination with the backrest / upper seat 4 changes at the same time, so that reclining conversion can be performed. The lower seat portion 5 is fixed in place by the stopper portion 10.

[0006]

【Example】

 Hereinafter, a reclining chair according to the present invention will be described in detail with reference to the drawings showing an embodiment thereof. Embodiment 1 As shown in FIG. 1, FIG. 2 and FIG. 3, leg portions 1, 1 are erected upright by a supporting portion 2 with a certain distance provided therebetween. The backrest 3 is mounted between the end sides. A reversible seat portion 6 having a double structure of a backrest / upper seat portion 4 and a lower seat portion 5 is provided between the leg portions 1 and 1. In this inversion type seat portion 6, the base ends of the backrest / upper seat portion 4 and the lower seat portion 5 are connected by a connecting member 7 such as a hinge, and further, the back end / upper seat portion 4 is in front of the base end. The leg portion 1 is connected and pivotally supported by a connecting rod portion 8. Then, the middle part of the lower seat portion 5 and the leg body portion 1 therebelow are connected and supported by a connecting rod 9. In the figure, 10 indicates a stop part.

Embodiment 2 As shown in FIG. 4, FIG. 5 and FIG. 6, the leg portions 1, 1 are erected by the support portion 2 with a certain space provided therebetween. A backrest portion 3 is mounted between the base end sides of 1. A reversible seat having a double structure of a backrest / upper seat portion 4 and a lower seat portion 5 having an auxiliary leg portion 11 extending from the tip thereof between the leg portions 1 and 1. The part 6 is provided. In the inversion type seat portion 6, the base ends of the backrest / upper seat portion 4 and the lower seat portion 5 are connected by a connecting tool 7 such as a hinge, and further the base end front side of the backrest / upper seat portion 4 and the leg body. The portion 1 and the connecting rod portion 8 are connected and supported by a connecting rod portion 8. Then, the middle part of the lower seat portion 5 and the leg body portion 1 therebelow are connected and supported by a connecting rod 9. In the figure, 10 indicates a stop part.

[0008]

[Effect of device]

 As described above, according to the present invention, it is possible to convert the chair into a normal chair or a reclining chair by reversing the backrest / upper seat part having a double structure backward. It will be possible. Also, during reclining conversion, the seat height, seat angle, and backrest inclination change at the same time, enabling an ergonomically ideal posture.
