Description

[Detailed Description of the Invention] The present invention relates to a chair that functions as both a reclining chair and a rocking chair. More specifically, the present invention relates to a multipurpose chair that can change its inclination angle and can also be used as a rocking chair.

In conventional ordinary chairs, the inclination angle of the seat back is fixed.
If this was to be adjustable and function as an easy chair, it would be necessary to provide a reclining device with a complicated structure. Also, it was impossible to use this as a rocking chair that swings back and forth.

The present invention eliminates the drawbacks of the conventional products described above, and provides a dual-purpose chair that can change the inclination angle of the seat back with a simple structure and operation, and can also be easily used as a rocking chair.
Hereinafter, the configuration of the present invention will be explained in detail based on the drawings.

FIG. 1 is an overall perspective view of the dual-purpose chair of the present invention, and numeral 1 in the figure is the seat cushion of the chair. A seat bag 2 is continuously provided upright on the rear side of the seat 1 at a required angle. It is preferable to provide a headrest 3 above the seat bag 2. These seat cushions 1, seat pads 2, and head rests 3 may be made by covering a core material with a cushion material and a covering material such as fabric, leather, or vinyl leather, as in a normal chair.

Support pins 6, 6' are protruded and fixed on both sides of the rear side of the seat cushion 1. (The support pin 6' on the opposite side is not shown.) Two side frames 5, 5' are fixed to both sides of the seat cushion 1 and the seat back 2. The side frames 5, 5' have an arcuate shape with a gentle curvature, with the lower side in contact with the floor bulging downward. Approximately central portions of the side frames 5, 5' are supported by the support pins 6, 6'. Note that the support pins 6, 6' have one long axis passing through the inside of the rear side of the seat cushion 1,
It is preferable that both ends thereof protrude to both sides, but in some cases, 6 and 6' may be provided as separate parts. In addition, the side frame 5,
5' is firmly fixed to one side of the seat cushion by another means, the side frame 5,
It is also possible to protrude support pins 6, 6' from approximately the center of 5' itself. In the illustrated embodiment, the side frames 5, 5' have a shape in which a linking member having a support portion in the center is bridged over a ring-shaped frame member. It is not limited to this, but it is also possible to form it with a plate-shaped body or the like as long as it has the gently arcuate lower side. Also, the material is metal pipe,
Any material can be used as long as it has the required strength, such as synthetic resin, wood, rattan, etc. Furthermore, it is optional to attach a shoulder hanging material or the like to the upper side portions of the side frames 5, 5' as required.

Next, both open ends of the leg frame 7, which is formed by bending an elongated material having the required strength, such as a metal pipe, into a substantially U-shape are removably pivoted to the support pins 6, 6'. Therefore, the leg frame 7 can rotate around its open end.

Further, front stoppers 8, 8' are fixedly installed near the front ends of the gently arcuate lower sides of the side frames 5, 5', and rear stoppers 9, 8' are fixed near the rear ends of the side frames 5, 5'.
9' is fixedly installed. (The rear stopper 9' of the side frame 5' is not shown.) The leg frame 7 can rotate between the front stopper 8 and the rear stopper 9 around the support pins 6, 6'. The intermediate portion of the leg frame 7 is configured to abut the front stoppers 8, 8' from the rear and the rear stoppers 9, 9' from the front.
In addition, in the illustrated embodiment, the front stoppers 8, 8' and the rear stoppers 9, 9' are each formed of one bar (or a pipe material), and are arranged between the lower sides of both side frames 5, 5'. Although this embodiment is preferable in that both side frames 5 and 5' are strongly integrated with each other, the present invention is not particularly limited to this embodiment. Instead, 8 and 8' and 9 and 9' are separated into side frames 5 and 5'.
There is no problem even if it is provided protruding from the bottom part. The side frames 5, 5' of these stoppers 8, 8' and 9, 9'
When attaching to the lower side, it shall be fixed with sufficient strength by means such as welding, and 8, 8',
9 and 9' should not protrude below the arcuate lower edge.

The present invention is constructed as described above, and the usage conditions of the present invention will now be described.

FIG. 2 is a side view showing the state in which the dual-purpose chair of the present invention is used as a normal chair. In this state, the leg frame 7 is in contact with the rear stopper 9 and forms an angle α with the floor surface F. The seat back 2 is inclined with respect to the floor F at an obtuse angle _θ1 .

Next, when the chair is to be reclined for use, the leg frame 7 is rotated forward about the support pin 6 along the arc shown by the chain line as shown in FIG. bring it into contact with. In this case, the angle between the leg frame 7 and the floor surface F is β, and the angle of inclination of the seat back 2 with respect to the floor surface F is an obtuse angle θ ₂ that is larger than the above θ ₂ , and the seat back 2 is inclined more rearward than in the case of FIG. The state will be as follows.

In this way, by simply rotating the leg frame 7 about the support pin 6, it is possible to very easily switch between the normal state and the reclined state at any time. If the leg frame 7 comes into contact with the stopper 8 or 9, if a means for locking the stopper and the leg frame is provided (for example, by providing a hook on the leg frame), the machine can be used in a stable state. More preferred.

Furthermore, if the leg frame 7 is removed from the support pins 6, 6' to create the state shown in Fig. 4, the chair will be in contact with the floor F only at the gently arcuate lower edges of the side frames 5, 5', so it will swing back and forth. be able to. Therefore, in this state, it can be used as a rocking chair.

As is clear from the above explanation, the chair of the present invention can be easily switched between the normal state and the backward leaning state by simply rotating the leg frame back and forth, and can also be used as a rocking chair by simply removing the leg frame. It is extremely convenient. Moreover, since it has a simple structure that does not require a special reclining device, it can be manufactured at low cost, and has great practical effects.
