Description

Chair which seat plate is moved to {A CHAIR OF SEAT SLIDING}

The present invention relates to a chair in which the seat plate is moved so that the seat plate of the chair is moved back and forth, and more specifically, by installing a seat plate moving device capable of moving the seat plate back and forth in the left and right frames to fix the front and rear chair legs. If you lean on the back of the chair while seated on the chair, the seat of the chair will move forward, making your seat comfortable, and if you put your posture upright, the seat will be repositioned so that the seat's position changes according to your seat. It's about things.

In many homes, schools and offices, many chairs are used. Most of the chairs are inconvenient when sitting on the chair for a long time because the seat plate is fixed.

In general, the posture of a person seated on a chair varies greatly from person to person. When sitting or working for a long time or studying in a chair, the posture becomes uncomfortable.

Therefore, to maintain a comfortable posture to be able to work or study for a long time, in order to maintain a comfortable posture should be in close contact with the back of the person.

However, in the case of a chair with a fixed backrest, the backrest is fixed at a certain angle, so that if you sit on the chair and study or work, your back falls off the backrest and you cannot maintain a comfortable posture. Even if the upper body is in close contact with the backrest, the backrest is not fixed and cannot rest comfortably.

In other words, the first time you sit on the chair, you sit deep in the chair's seat and the back makes contact with the back, so you get a comfortable posture, but when your back is in contact with the back, your hips are pushed back slightly. You should change your posture from time to time, and if you tilt your upper body back to rest, your butt will be uncomfortable.

In order to eliminate this problem, there have been chairs in which the seat plate and the backrest move at the same time in the past. In addition to the front and rear of the seat, as well as moving left and right, the back hurts, and this method also rests on the back of the back for a long time while working or studying, the hips are pushed to the end of the seat, so you have to change your posture from time to time. Rather, the structure for moving the seat and the back is complicated, which requires a lot of manufacturing costs and frequent breakdowns.

Therefore, the present invention was created in order to eliminate the above-mentioned problems, by moving the seat back and forth so that the position of the seat is changed according to the physical condition of the person seated on the seat to always be seated in the chair in a comfortable posture It is an object of the invention to provide a chair to which a seat plate is moved.

Still another object of the present invention is to provide a chair to which a seat plate is moved to reduce manufacturing costs by simplifying a device for seat plate movement.

Characteristic of the present invention for achieving the above object is the chair in front and rear is fixed to the left and right frame, both ends of the transverse is fixed to the left and right frame and the seat plate is installed on the top of the frame, fixed to the left and right frame A guide plate installed to move the moving plate inside;

A moving plate installed inside the guide plate and moved back and forth, and having a bracket for fixing the seat plate to the upper side thereof;

One end is fixed to the movable plate and the movable plate is elastically supported, and the other end is configured as a spring fixed in the transverse direction. Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a perspective view showing the bottom of the chair to which the present invention is applied, Figure 2 is a partial perspective view showing the main part of the present invention, Figure 3 is a partially enlarged cross-sectional view showing a front sectional view of Figure 1, 1 is a leg, 2 is frame, 3 is transverse, 4 is seat, 5 is backrest, 6 is guide plate, 7 is moving plate, 8 is bracket, 9 is spring and 10 is ball bearing.

As shown in the figure, the front and rear chair legs 1 are fixed to the left and right frames 2, the transverse 3 is fixed across the left and right frames 2, and the upper part of the frame 2 is fixed. In the chair provided with a backrest 5 on the rear upper part of the seat plate 4 after the seat plate 4 is installed, the guide plates 6 having a "C" shaped cross section are fixed to the inside of the left and right frames 2, respectively. The inside of the guide plate 6 is installed so that the moving plate 7 is moved back and forth, and a ball bearing 10 is installed between the guide plate 6 and the moving plate 7 so that the moving plate 7 Make the movement smooth.

Then, the bracket 8 is fixed to the inner upper portion of the movable plate 7 before and after, and then the seat plate 4 is fixed to the bracket 8, and the movable plate 7 is disposed on the inner rear side of the movable plate 7. One end of the spring 9 is fixed so as to be always located in the backrest 5 direction, and the other end of the spring 9 is fixed to the transverse 3.

At this time, the present invention is fixed to one end of the spring (9) to the frame (2) or in the case of the chair is not provided with the transverse (3) is fixed one end of the spring (9) to the frame (2) It can be implemented to be fixed to the auxiliary plate, as shown in Figure 4, the left and right frame (2) to be a guide plate, the inside of the moving plate 7 fixed to the bracket 8, the seat plate (4) It can also be implemented to be supported by the spring (9).

The present invention as described above is seated on the chair (5) so that the back contact with the back (5), while the seat or seat (4) is pushed back to the back of the chair while working or studying while working or studying Simultaneously moved forward, the seat plate 4 is supported by the spring 9, so if the posture is slightly modified, the seat plate 4 is pushed to the rear side by itself, so that the posture can be relaxed.

In other words, when seated on the chair at the first time comfortably seated on the chair in the correct posture, even if the hips are pushed forward in front of the seat 4 little by little, without knowing the hips are not pushed, the seat 4 is pushed, Since the seat plate 4 is supported by the spring 9, even if you move the body a little, you can easily correct the posture in the seated state at the beginning, and even if the seat plate 4 is inclined a lot in the backrest direction for rest, Since the back is inclined while moving forward, the body is inclined to the rear in a state where the hips are positioned in the entire seat plate 4, so that the user can relax comfortably.

When the posture is corrected afterwards, the seat plate 4 is moved to the rear side (backrest direction) by the elasticity of the spring 9 when the force is slightly applied to the leg so as to be in the first seated state.

In the present invention as described above, since the position of the seat plate 4 of the chair is changed according to the physical condition of the person seated on the seat plate 4, it is possible to always take a comfortable posture, and the moving device for moving the seat plate is simple to reduce the manufacturing cost. It is an invention that can be effected.
