Description

Chair {CHAIR}

The present invention relates to a chair having a backrest and a seat plate, and more particularly to a chair in which the backrest and the seat plate operate individually.

It is an object of the present invention to provide a backrest and a seatboard to distribute the load of the body concentrated on the hips and the waist when seating to the seat and the backrest so that the chair can be more comfortable and comfortable in working for a long time. It is to provide a chair that can be arbitrarily adjusted and used by the operation switch in the form.

As is well known, the types of chairs are appearing innumerably.

Nevertheless, most of these chairs can be relieved from mental and physical fatigue while sitting comfortably for a long time while working or relaxing. For example, a chair configured by adjusting the structure of the chair and the backrest with a steel plate spring and connecting one end thereof with a coil spring mounted on the seat plate shaft is fixed.

However, these chairs do not evenly distribute the load of the body, which is concentrated on the hips and back when seated, and are concentrated on either side. The chair, which has a slight flow force due to the elastic force of the coil spring and the coil spring, is in a position where the backrest and the seat plate are inclined at all times, that is, the seat back and the seat plate are inclined at all times so that the seater can not rest or work for a long time As a result of having to maintain the posture in which the body's weight is concentrated, it is accompanied by a problem of adding fatigue.

In the present invention, the rear of the seat is lowered in a state that the seated person can see the most comfortable work or take a rest by operating the operation switch installed on the armrest of the seat to solve the drawbacks of the conventional chair as described above. And the backrest is a chair having a structure that is tilted backwards is characterized by providing a chair that the seat can be arbitrarily adjusted by the switch back, the angle of the seat plate, the armrest that can be folded back, the length of the head restraint.

Angle can be adjusted arbitrarily, and the gear roller (3-3-, 2 ') with stop groove (3-2, 2') at the end of the back plate and seat plate hinge (3-12, 12 ') (4-10, 10') 2, 2 ') on both sides of the seat plate and the seat plate rails (5-3, 3') of the seat plate support [Fig. 5] and into the stop grooves 3-2, 2 'attached to the gear rollers. 6-5, 5 'between the seat plate operation is operated by the adjustment switch installed in the armrest of Fig. The coil springs (3-6, 6 ') (3-7) are mounted between the seat operation and the back operation to always push the operation in a constant direction so that the back and the seat are fixed and attached to the armrest. Coil springs 6-2 and 2 'are also attached to the switches 6-1 and 1' so that the back and seat plates are fixed unless the switch is arbitrarily operated, and the headrest 4-1 installed on the back is also operated. When the switch (4-3) is operated, the head restrains upward by the coil spring (4-2) that pushes the head restraint, and the switch is also fixed by the coil spring (4-4), and the switch fixing pin (4- 11) The head restraint operation (4-13) adjusts the head restraint, and when restoring to the original position, press the head rest down.

In addition, the switch adjustment pins (6-10, 10 ') connected to the back plate and the seat plate adjustment switch attached to the left and right armrests [FIG. 6] are between the back plate operation (6-9) and the seat plate operation (6-8, 8'). It is connected to the strong tensile line (6-7, 7 ') to facilitate the operation through the small rollers (6-4, 4'), the hinge (6-6, 6 ') of the armrest [Fig. 6] Perforated hinges allow the back and seat plate adjustment lines (6-7,7 ') to pass through, and the opening and closing screw (6-5,5') can flip the armrest back as shown in FIG. The armrest is fixed by tightening the opening and closing screw.

Seat plate and back plate adjustment line (6-7,7 ') is pulled out and is caught on the control line. , 2 ') and back stops (4-5), the back may be flipped backwards, and the latter half of the seat may be lowered. At this time, the tension springs (3-8, 8') connected to the back and seat are installed. The back spring is excessively tilted back or the seat is suddenly lowered by the action of the tension springs (3-11, 11 ') connected to the The coil springs (3-7) (3-6, 6 ') installed between the back and the seat operation keep the back and the seat operation between the back and the seat stop, and then operate the switch. The seat is lowered as the liver falls out of the stop, but if the switch stops operating, it takes time between the stops again, so that the load on the body concentrated on the hips and waist at the time of seating can be evenly distributed on the back and the seat. 1) Pressing the switch (4-3) pushes down the head restraint (4-13) hanging on the fixed hinge (4-11), and moves the head by the elastic force of the coil spring installed under the head restraint (4-1). The pedestal was raised up and a coil spring (4-4) was installed in the switch (4-3) so that the head restraint was always caught in the adjuster (4-13) unless the switch was operated.

The armrest was released from the opening and closing screw (6-5, 5 ') in Figure 6 to be able to be flipped back as needed, and when the original position is tightened, the armrest is fixed by tightening the tightening screw.

As described above, the chair of the present invention can be easily used by installing a switch on the left and right armrests so that the angle of the back plate and the seat plate can be individually adjusted to a desired shape so that the seated person can work or relax in the most comfortable and comfortable posture. Coil springs are installed in the switch, and when the switch is operated, one end of the operation is removed from the stop groove, and the seat is moved, and when the switch is stopped, the operation is caught in the stop groove and the seat is stopped. It can be conveniently used in self-desired form, so that the body load concentrated on the hips and waist when seated is distributed evenly on the head restraint, back plate, and seat plate. , Especially if the occupant is most appropriate for his or her body There is an effect that can be operated conveniently used for.
