Description

Backrest chair with cover {the back of a chair for both chair provided with a cover}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair, and more particularly to a chair for backrest with a cover for protecting a seat from dust, rain or snow.

In the stores, camping areas, and beaches, parasols are installed for the purpose of increasing the convenience of consumers and campers and increasing sales.

Here, the outdoor chairs and benches are installed in buses, passenger stops, outdoor stadiums, parks, and the like in addition to the above-described places, and are preferably made of a synthetic resin material resistant to moisture due to the nature of the outdoor which is left in snow or rain.

These chairs usually consist of a seat, a backrest, and a support leg supporting the seat. Since the upper surface of the seat is always exposed, dust accumulates on the upper surface of the seat. Is generated.

In order to solve some of the problems described above, a through hole for drainage was formed in the center of the sheet, but dust, rain, and snow stains were still present on the upper surface of the sheet, and water on the upper surface of the sheet was not completely drained.

SUMMARY OF THE INVENTION An object of the present invention for solving the above problems is to provide a chair for back-rest combined with a cover to prevent dust, rain, snow on the seat of the chair.

In order to achieve the above object, the present invention provides a chair having a cover, comprising: a seat comprising a seat, a back, and a leg for supporting the seat, the seat having a hinge portion having a through hole at a rear end thereof; A backrest provided with another hinge portion having a through hole at a lower end portion, the hinge portion being located between the hinge portions of the sheet; Hinge pins coupled to the hinge portions of the seat and the backrest; A torsion spring coupled to a hinge pin to elastically close the backrest toward the seat; It is provided on the front of the backrest, characterized in that made of a shock-absorbing rubber to mitigate the impact and noise when the backrest is closed.

Therefore, when sitting on the chair can be seated after squeezing the backrest upwards, and when standing up, the backrest closes to the upper surface side of the seat by the restoring force of the torsion spring, thereby preventing dust from accumulating on the upper surface of the seat. In the rain, the upper surface of the seat and the back of the back contacting the clothing do not get wet, so that the seated person can sit in a clean chair without any effort, thereby improving user satisfaction and reliability of the product.

Specific features and advantages of the present invention will become more apparent from the following description taken in conjunction with the accompanying drawings.

In Fig. 1, the chair for backrest with the present invention is composed of a seat 1, a backrest 4, a pedestal 7 and a leg 8.

The seat 1 is provided with hinge parts 2 having through holes 3 at both rear ends thereof, and the backrest 4 is provided with other hinge parts 5 having through holes 6 at the center of the lower end part. , The hinge part 5 of the backrest 4 is located between the hinge part 2 of the seat 1.

And the leg 8 is fixed to the seat 1 bottom surface all directions, and supports the whole chair.

Here, the hinge pin 9 is coupled to the hinge portion 2 of the seat 1 and the hinge portion 5 of the backrest 4, and the torsion spring 10 is coupled to the hinge pin 9. One end of the torsion spring 10 is supported on the back of the backrest 4 and the other end is supported on the bottom of the seat 1 so that the backrest 4 is elastically supported toward the seat 1 side.

And both sides of the upper backrest 4 is provided with shock absorbing rubber 11 to mitigate the impact and noise generated when the backrest 4 hits the seat 1 when it is closed.

In this case, the shock absorbing rubber 11 may be provided on the backrest 4 as described above, but may be attached to the upper surface of the seat 1, as long as it serves to alleviate the impact between the backrest 4 and the seat 1. The shape and attachment location may be modified by those skilled in the art.

In the back seat chair provided with the cover of the present invention having such a configuration, the backrest 4 is always folded to the seat 1 by the elastic restoring force of the torsion spring 10.

When sitting in a chair in such a state to sit down after the free end of the backrest 4 is lifted upwards, the torsion spring 10 is elastically deformed.

On the other hand, when standing up in the chair, the elastically deformed torsion spring 10 is restored and the backrest 4 pivots around the hinge pin 9 and overlaps the upper surface of the seat 1.

At this time, the impact force of the backrest 4 hitting the seat 1 is changed according to the force of the torsion spring 10 and the weight of the backrest 4, and the shock absorbing rubber 11 on the front of the backrest 4 absorbs such a shock, This will minimize product damage and noise.

When the seat chair is equipped with the present invention cover is seated on the chair, the backrest (4) is automatically folded to the seat (1), so that the upper surface of the seat (1) by the backrest (4), accordingly Dust does not accumulate on the upper surface of the sheet 1, and thus it does not get wet by snow or rain.

Therefore, the chair of the present invention is in contact with the clothes (1) upper surface and the back (4) front is always kept in a clean state, so that even if the snow, rain falls after sitting on the chair without a separate cleaning work is a problem that the clothes are heavily polluted .

On the other hand, the chair having a backrest combined with the above-described cover has a configuration such that the backrest 4 is forcibly folded by the torsion spring 10, so that the backrest 4 is folded by the weight of the backrest 4 without the torsion spring 10. You may.

That is, when the backrest is unfolded, if the angle formed by the backrest and the seat is formed to be smaller than 90 °, the backrest in the unfolded state is naturally folded onto the seat while being moved toward the front side of the seat by its own weight.

In this way, if the backrest is unfolded to be smaller than 90 ° and closed automatically by its own weight, the torsion spring is not required, thereby lowering the labor and production cost.

In addition, in the above description, only the structure in which the backrest 4 is rotated about the hinge pin 9 is illustrated and described, but the backrest 4 and the pedestal 7 may be rotated around the hinge pin 9 together. Such a simple structural change can be easily changed and implemented by those skilled in the art.

In addition, a leaf spring may be used instead of the torsion spring 10, or a compression coil spring or a tension coil spring may be used by a slight structural change.

According to the chair according to the present invention with a cover according to the present invention as described above, when sitting on the chair can be seated after hitting the backrest 4 to the upper side, standing up the backrest by the restoring force of the torsion spring (10) ) Closes to the upper surface of the sheet 1 and serves as a cover of the sheet 1, thereby preventing dust from accumulating on the upper surface of the sheet 1, and the upper surface of the seat 1 and the backrest 4 which are in contact with clothing even in the rain or rain. The front surface is not wet, so that the seated person can sit in a chair in a clean state without any effort, thereby improving user satisfaction and product reliability.
