Description

Sofa back transformed into bed cover {Transform into bed cover form back of sofa}

The present invention is a sofa configured to be used as a bed and a steamer by converting the sofa back, the backrest is divided into four equally divided into the front board, two top boards, the back board, the hinge and the showbar, each of the boards in a straight line to the elasticity of the hinge The two top boards are folded together into the English alphabet (V) shape, and the top boards are folded into the Korean consonant (a) shape. And a sofa back configured to wrap with a back board, and a sofa back with two folded top boards configured to extend the space occupied by the backrest and to form a tunnel by covering the unfolded backrest with a mat. .

In modern times, various types of products are subdivided into various lifestyles in various fields.

However, these products cannot be used for a specific purpose, so they are not used frequently, so they are not as effective as their value.

Sofas have a variety of subdivided products that have their own characteristics on the market.

Ondol sofa is a type of sofa that combines a functional mat that generates heat on a cloudy top plate instead of a cushion mat, and this thermal mat is hard and slippery, so it is not enough to be used as a sofa.

Ondol sofas need to be seated on the mat and lean on the back, so if the mat width exceeds 60 cm, it will lose its function as a sofa and become a product close to the bed.

Thus, the ondol sofa has developed into a universally transformed form of a couch.

Such couch-type sofas are more intimate to sleep as the mats are wider to use as sofas because they are closer to the bed side than the sofa functions, and the mats are narrow to use as beds.

It is true that such ondol sofas are both inconvenient to use as sofas and beds. So I want to realize that I can fully utilize the functions of both products without compromising the inherent shape of the sofa and bed.

In addition, by using the back of the sofa to cover the mat top to be able to steam.

In addition, by opening the armrest on the side of the mat to be able to freely adjust the length of the mat according to the number of seats.

Therefore, the present invention is intended to be able to fully utilize the function of the sofa without damaging the features as an ondol sofa and to be used as a bed and to be able to steam.

We also want to extend the length of the mat so that the sofa mat can be adjusted to all the citations.

In order to achieve this purpose, the space occupied by the backrest should be utilized in order to expand and narrow the narrow mat width of a general sofa, and in order to utilize this space, the thickness of the backrest may be moved or converted to another place to make it thinner. do.

The width of the sofa mat is less than 60cm and the thickness of the sofa back is about 30 ~ 50cm. The lower part of the sofa back cannot be used as a dead space.

In addition, it is possible to convert the upper surface of the heating mat to cover the tunnel shape by using the backrest to steam the thermal mat, and to combine the heating plate or the surface heating element that generates heat to the backrest, and to release the substance or powder that emits far infrared rays on the heating plate. It is intended to be configured to be able to emit far infrared rays into the backrest by applying.

In addition, to extend the length of the sofa mat is to separate the armrest from the mat to be able to move independently.

To achieve this purpose, the backrest is divided into four parts on the front, two tops, and the back to form a board so that the backrest can be moved and the thickness of the backrest can be reduced.

The four boards are joined by a hinge and a showbar so that the pushing force and the direction of elasticity are combined so that the board can be unfolded in a straight line.

Combine the two top boards with a hinge that incorporates a spring that springs up to extend straight or a springless hinge and mount the stopper so that the board does not bend more than 180 degrees.

The shape of the front board of the backrest is shaped like the Korean consonant (a) and combined with the top board, the hinge, and the showbar, so that the two top boards are folded into the English alphabet (v), so that the front board is wrapped and the back board is opposite to the top board. The hinge and the showbar are combined to block the side of the front board so that the two folded top boards are located in the space between the front board and the back board.

On the upper lower part of the front board made of Korean consonants (a), two freely connected round rods pass through the fixing ring so that the round rods can be rotated by the rotating plate, and the central axis of the rotating plate passes through the upper board of the front board to engage with the handle. do.

If the handle is rotated 1/4 turn, the round bar is rotated by the rotating plate, and the lock bar is configured to protrude the end of the round bar at the lower end of the upper board.

In order to be able to steam on the mat, the backboard board covers the top surface of the mat by covering the top surface of the mat by applying a functional powder that radiates far-infrared rays to the inner surface of the backboard board by combining a heating plate or a heat source such as a planar heating element. Formed to emit far infrared rays into the backrest.

In order to be able to vary the sofa mat by citation, the bearing units are fixed in two rows side by side on the side of the mat frame, and through the round bar in the bearing unit, the armrests are combined with the armrests so that the armrests can be separated from the mat side.

The double armrests are constructed so that the outer armrests surround the three sides of the inner auxiliary armrests, and the lower part of the inner auxiliary armrests are joined to the board by hinges, and the boards are fixed to the bearing rails at the inner bottom of the outer armrests. It slides forward and backward inside the outer armrest and the auxiliary armrest is folded toward the mat so that it is horizontal with the mat.

Another configuration of the armrest is to make the armrest two-stage, combine the upper armrest and the lower armrest with a hinge, and mount the handle outside the armrest so that the armrest can be folded or fixed by the locking device so that it can be converted into a bed and a steamer. It becomes the ondol sofa.

As described above, the present invention can be utilized as a bed by widening the width of the mat by utilizing the bossy space occupied by the backrest by moving the board upside down by thinning the thickness of the backrest by connecting the board separated into four equal parts. have.

In addition, a heat source such as a heating wire or a planar heating element is installed inside the backrest board, and the backrest is coated with a functional powder that emits far infrared rays on the upper surface of the heat source to cover the upper surface of the mat to radiate far-infrared rays into the tunnel-formed sofa so that it can be steamed. have.

In addition, the length of the mat can be changed by spreading the armrests on the mat, so the sofa can be used as a multi-quoter.

By converting the sofa into a steamer as described above, the unique functions of each product can be fully realized, and various functions can be utilized in one product, thereby increasing the utilization of the product, thereby reducing the purchase cost of products necessary for cultural life. There is an economic advantage to doing this.
