DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover device for covering a lower surface of a seat plate of a chair.

[0002]

2. Description of the Related Art In a chair provided with a seat plate support below a seat plate, such as an office swivel chair, to improve the overall appearance of the chair,
The back of the seat plate and backrest is often covered with a plastic cover. In these chairs, the appearance of the seat plate support fitting itself is made of metal in the lower portion of the seat plate appears, in terms of material in terms of shape, rather <br/> to put the unity of design fried as described above, it is the seat plate and the backrest of the rear surface is Ru We covered with a cover plus <br/> tick.

[0003] In this case, not only to cover the back side of the backrest seat plate and back in the plastic cover, in order to give a sense of unity on the design, also the lower part of the seat plate support bracket of the seat plate, seat plate back of a plastic cover has to demand that the cover together. However, in this case, when performing maintenance of the seat plate support bracket unit must remove from the seat plate the entire cover of the seat plate back surface, a problem that there Ru takes time maintenance.

In Japanese Utility Model Publication No. Hei 6-10878,
A cover of the seat plate cover and seat plate support bracket, there is disclosed that attached separately. However, Oite to the chair,
For a person to facilitate the operation in a state of being seated, the two operating levers for adjusting the inclination angle of the rest height adjustment and the back of the seat, but is provided on the left and right outer side of the seat plate support bracket, According to the structure described in Japanese Utility Model Publication No. 6-10878, there is a disadvantage that not only the seat plate support bracket cover but also the seat plate cover must be removed in order to perform maintenance of the operation lever portion.

[0005]

[0008] In view of the above problems the prior art has, the cover of the seat plate support bracket, easily installed, to allow removal,
By simply removing the seat plate support bracket cover, not only the washer support bracket but also the maintenance of the operation lever mechanism for adjusting the seat height and the tilt angle of the backrest can be performed, and the design It is another object of the present invention to provide a cover device for a seat plate support fitting which is excellent from the above.

[0006]

In the present invention, there is provided a means for solving], in order to achieve the above object, adopts the following means. (1) In a chair provided with operation levers for adjusting the height of the seat and adjusting the inclination angle of the backrest on both sides of the lower surface of the seat plate supporting bracket for supporting the seat plate,
The seat plate support bracket cover covering from below, in a size that covers the seat plate support bracket, a box-shaped base top surface and rear surface is open, so as to cover the periphery of the operating lever, the wing from the side of the base with the top surface is <br/> chromatic and protrusion opening protruding to the left and right, the lower surface of each protrusion of the left and right, the window opening <br/> provided for operably through the operating lever from below, respectively Between the seat plate and the seat plate support bracket.
The seat plate cover that covers the seat plate from below,
And an upward recess at the central part
With a shape that is inflated around the rest
In the recess of the seat plate cover, the seat plate support
With the work lever and the seat plate support bracket cover
Ru attached fitted in the recess of the seat plate cover.

(2) In the above item (1), the seat plate support bracket cover is attached by engaging with the seat plate support bracket and / or the seat plate cover.
ing.

(3) In the above item (1) or (2) , the operation lever is attached to the seat plate support bracket cover.

[0009]

[Action] seat plate support fitting cover, a size to cover the seat plate support bracket, a box-shaped base top surface and rear surface is open, so as to cover the periphery of the operating lever, the left and right wing from the side of the base projecting and a projecting portion having an upper surface opens, the lower surface of each protrusion of the left and right, since the each of the operating lever is provided with a window for operably through from below, the seat plate support fitting other than the operation lever And cover the control lever
The, from the outside of the cover, without any hindrance, et al., May be engineered
It is possible to sea urchin. Also, when removing the seat plate support bracket cover, not only the seat plate support bracket, also the inspection and repair of the operation lever can be performed easily in a short time.

Furthermore, between the seat plate and the seat plate support bracket, a seat plate cover for covering the seat plate from below, has a lower surface of the central portion, the portion extending to the right and left by connecting the center thereof, otherwise The surrounding part of the seat is inflated, and the seat plate support bracket and the operation lever are arranged in the recess of the seat plate cover,
Since attachment of the seat plate support fitting cover fitted in the recess of the seat plate cover, not Deppara large seat plate support fitting cover relative to the seat plate cover, designed to cause a sense of unity to the two covers, and the seat plate well unity of the shape of the support bracket cover, appearance as a whole is good casting.

In the above-mentioned structure, if the seat plate support bracket cover is configured to be attached by engaging with both or one of the seat plate support bracket and the seat plate cover, the seat plate support bracket may be provided with screws or the like. In comparison, attachment and detachment work can be performed easily. In addition, by selecting the engagement structure, it is possible to obtain a good-looking attachment structure without rattling .
