<P>PROBLEM TO BE SOLVED: To provide a multiuse chair having functions of serving as a chair for dining, a chair for studying and a chair for resting and effectively used in a narrow space by attaching importance to the height of the backrest and the reclining function. <P>SOLUTION: The front end of the backrest/seat part 2 is connected and pivoted at the upper end of the seat part 1, the front end of the backrest/seat part support coupling, where a rear leg part and a rear end are connected and pivoted, is connected and pivoted at the intermediate part of the backrest/seat part 2, the backrest part lower part is connected and pivoted at the backrest/seat part rear end, and the rear end of a backrest support coupling 5 whose front end is connected and pivoted to the front part of a backrest/seat part support coupling 4 is connected and pivoted to the lower part of the backrest part positioned in the lower part of the connecting and pivoted position. When the seat part 1 is upward rotated, the backrest/seat part and the backrest part are associated with each other to be formed into a high-back chair. <P>COPYRIGHT: (C)2004,JPO
The present invention relates to a chair which can be easily converted to a versatile use simply by rotating a seat upward.
Conventional chairs include those that recline the backrest in order to respond to various uses.The mechanism that reclines the backrest incorporates gears at the connection between the seat and the backrest member for adjusting the backrest angle. And relatively complex mechanisms operatively connected between a movable chair frame and a base assembly. Most of the backrests are reclined and at rest height.
In a one-room apartment in an urban area, it is not possible to secure a space for a dining chair, a study chair, and a resting chair at the same time. When dining or studying in a dining chair or study chair, a lower backrest increases freedom of body and is convenient for use and there is no feeling of oppression, but when relaxing, the seat tilts and the backrest The higher the slope, the more comfortable you can relax. In the case of a dining chair or a study chair, if it is used as a resting chair to be used at a dining table or a desk, it must be moved. The inventor of the present invention has filed a Japanese Utility Model Publication No. 7-50984, entitled "A Reclining Chair with Changing Seat Height," in order to solve the above problems. However, the reclining chair has a problem in that it is bulky and bulky and takes a lot of time to move, and there is a problem that the number of parts is large and productivity is low and the cost is high.
It is an object of the present invention to provide a low-priced, lightweight chair that emphasizes the height of the backrest and the indispensable function of reclining, with the function of functioning as a dining chair or a study chair and a resting chair.
In order to achieve the above object, in the chair according to the present invention, the seat portion is located below the seat portion also serving as a backrest, and an upper portion of the seat portion is connected and pivotally supported at a front end of the seat portion also serving as a backrest. And the legs are connected and pivoted, and the front end of the backrest / seat support connector is connected and pivoted at an intermediate portion of the backrest / seat, and the rear end is connected and pivoted with the rear of the legs, and the backrest. The lower end of the portion and the rear end of the backrest / seat portion are connected and pivotally supported, and the rear end of the backrest support connector is connected and pivoted below the pivotal position, and the front end is the backrest / seat of the backrest / seat support connection connector. As a mechanism that is connected and pivotally connected to a part located behind the pivotal position of the part and the backrest combined seat part support coupler, the seat is tilted to a position where it can be used as a seat by rotating the seat upward. While the backrest combined seat and backrest When is formed in the extending direction it is to tilt simultaneously.
A versatile chair which can be used as a backrest in a state of a stool from which the backrest portion and the backrest support coupler of the versatile chair are removed.
Since the seat portion, the backrest portion and the backrest portion are integrated, the whole can be changed by a simple operation.
Since the structure is simple and the number of parts is small, there are few troubles and the whole chair can be made compact and lightweight.
Embodiments of the present invention will be described based on examples with reference to the drawings.
FIG. 1 is a side view, in which a front end of a backrest / seat 2 is connected and pivoted to an upper end of the seat 1. In the middle part of the backrest / combination part 2, the front end of the backrest / combination seat support connection device, which is connected and pivoted at the rear and rear ends of the legs, is connected and pivotally supported, and the lower part of the backrest part is provided at the rear end of the backrest / composition seat. The front end of the lower portion of the backrest below the connection pivot position is connected and pivotally supported, and the rear end of the backrest support connection device 5 is connected and pivotally supported by the front portion of the backrest / seat support connection device 4. You. FIG. 2 is a side view, and when the seat portion is rotated upward, the backrest seat portion and the backrest portion are interlocked. FIG. 3 shows a state in which the seat portion, the backrest dual-purpose seat portion, and the backrest portion extend in the extending direction. FIG. 4 shows a high-back chair in a state in which the seat and the backrest are also lowered. FIG. 5 is a three-dimensional view of a normal chair. FIG. 6 is a three-dimensional view of a high-back chair.
Even in a small place such as an apartment in an urban area, a small chair can be widely used because a dining chair, a study chair, and a rest chair can be used together with a simple operation.
The operation is simple because the whole is linked simply by rotating the seat part upward.
Since the number of parts is small, failures are reduced and the weight can be reduced.
In the case of an ordinary chair, the backrest can be made low and thin, so it is not bulky and does not have a feeling of oppression.
FIG. 1 is a side view of an embodiment.
FIG. 2 shows a state that changes in conjunction with it.
FIG. 3 shows a state in which it is changed and interlocked and extended.
FIG. 4 shows a high-back chair.
FIG. 5 is a three-dimensional view of FIG. 1;
FIG. 6 is a three-dimensional view of FIG. 4;
