Description

Sofa bed {A sofa bed}

The present invention relates to a sofa bed in which a user can take a rest and sleep while sitting or lying down.

Specifically, the present invention relates to a sofa bed to improve the quality of use by disposing a bed mattress suitable for sleeping and a sofa mattress suitable for resting on a seat portion according to a user's choice.

More specifically, the bed mattress can be configured to provide additional functions such as thermal massage, etc., as well as selectively appearing and retracting to the seat as needed, so that usability and space efficiency are improved. It's about the daybed.

In general, a sofa is one of the pieces of furniture used for a user to sit comfortably and take a break. A sofa frame can provide a space by forming a predetermined height from the floor, and is installed on the sofa frame to protect the user's back. It consists of a backrest that supports and a sofa mattress that is provided in the seat portion of the sofa frame and provides a cushion when the user sits down.

In the above, the sofa mattress and the backrest are formed by forming a sheet with a coil spring, a material capable of absorbing shock, or a sponge or other elastic material, and covering the outer surface with natural or artificial leather and a fiber material. do.

In the conventional sofa made as described above, when the user sits on the sofa mattress and the cushion built into the backrest, the user's load is absorbed and comfort is provided.

On the other hand, the bed provided in the interior of a general home is to provide a comfortable and comfortable bed for humans to lie down on, and is mainly composed of a bed mattress and a bed frame supporting the bed mattress.

Since such a bed occupies a lot of occupied space, it is difficult to utilize other spaces in the place where it is installed.

In particular, as the bed culture has recently spread, there have been problems such as not being able to install and use other furniture, such as sofas, as well as more difficult to use space because beds are used in narrow spaces.

Accordingly, various sofas and beds designed to be used in combination with sofas and beds capable of doubling space utilization, use efficiency, and economic feasibility have been proposed because a bed is usually folded and used as a sofa.

One of them is Korean Utility Model Application No. 20-2007-0005179 (name: sofa bed/2007.03.29.). In the conventional bed configured, the support and the mattress are divided into a part in the longitudinal direction to form a divided body, and the divided body is selectively supported at various angles while adjusting the rotational-side divided body upward in both directions. A bed for installing an angle adjuster to do so is described.

And, in Korean Patent Application No. 10-2015-0140895 (name: sofa bed / 2015.10.07.), as known in the publication, the leg supported on the ground and formed with a bent part; a seat board to which the legs are coupled to both sides; a backrest that is vertically disposed on one long side of the seat board and is horizontally deployed while being rotated; a hinge rotatably connecting the seat and the backrest; It includes a fixing means to keep the backrest horizontal when the backrest is horizontally deployed, and the seat plate has side frames formed with insertion grooves into which the bent parts of the legs are inserted, formed on both sides, and composed of a cushion formed between both side frames. That is, the side frame has an arc-shaped end protruding on one side, an insertion groove is formed on the other side, and a bed made of a slit is formed on the inside of the insertion groove.

On the other hand, in Korea Patent Application No. 10-2001-0011296 (name: sofa and bed / 2001.03.05.), as is known in the gazette, both sides and the back plate, the front plate, the top plate are assembled with bolts and pieces by splicing A bed is installed inside the couch, two armrests, two cushions and two cushions, and there is a cushion in it, and a sofa configured to become a bed when pulled and unfolded is described.

In addition, in Korean Utility Model Application No. 20-1997-0008231 (name: sofa double bed / 1997.04.19.), as is known in the gazette, arms installed upright with a certain width maintained on both sides of the body frame A distance member and a horizontal cushion member having a back and forth sliding means with a cushion spring embedded between the armrest members, a backrest member having a rear end of the horizontal cushion member that can be folded when sliding the horizontal cushion member forward and backward, and a rear side of the backrest member. A bed made of an auxiliary cushion member that slides back and forth on a guide support bar according to the presence or absence of fixation and release of a locking member is described.

Korean Utility Model Application No. 20-2007-0005179 (2007.03.29.) Korean Patent Application No. 10-2015-0140895 (2015.10.07.) Korean Patent Application No. 10-2001-0011296 (2001.03.05.) Korean Utility Model Application No. 20-1997-0008231 (1997.04.19.)

However, the conventional beds and sofas as described above are intended to be used by selectively forming a sofa and a bed by folding or unfolding a folded mattress, and have a problem of poor structural stability due to low structural durability.

In addition, as the folding type mattress is applied, various additional functions (eg, thermal massage, etc.) cannot be given, and thus the quality of use cannot be improved.

In addition, when unfolded and used as a bed, as the occupied space increases, there is a problem in that the efficiency of space use in the facility space decreases.

The present invention has been proposed to solve the above conventional problems, and an object of the present invention is to allow a user to sit or lie down to rest and sleep, a bed mattress suitable for sleep and rest according to the user's choice. An object of the present invention is to provide a sofa bed that is designed to improve the quality of use by disposing sofa mattresses suitable for use on a seat unit, respectively.

Another object of the present invention is to configure a bed mattress so that additional functions such as thermal massage can be provided, as well as to perform selective reappearance to and from the seat as needed, so as to improve usability and efficiency of space use. It is to provide a sofa bed that has been used.

In order to achieve the object of the present invention as described above, a sofa bed according to the present invention includes a seat body having a seat portion configured to support a sofa mattress at a height relative to the floor; In a sofa bed including a backrest provided to be connected to the seat portion of the seat body and to support the back of a seated user; operating means provided in the seat body and supplied with power to selectively cause a bed mattress accommodated in an accommodation space provided between the seat body and the backrest to enter and exit the upper portion of the sofa mattress; It is characterized in that further comprising.

The actuating means is made of a 'electric cylinder' having an actuating rod to which a part of the bed mattress is bound to move in a straight line by receiving the rotational force of the actuating motor to form a rotational force by receiving power from the power supply unit. characterized by

In the sofa bed according to the present invention made as described above, as the user sits down on the sofa mattress provided in the seat part of the seat body to take a rest or lie down on the bed mattress selectively disposed in the seat part, Usability is formed by the user's selection, and the quality of use is improved.

In addition, a bed mattress suitable for sleeping and a sofa mattress suitable for resting are disposed on the seat through the operating means so as to be usable, respectively, so that space usage efficiency is improved.

In addition, the bed mattress can be selectively configured to provide additional functions such as thermal massage, thereby improving usability.
