Description

Electric sofa drive and sofa back {drive system and back of electric motor sofa}

The present invention is to advance the ondol sofa mat by using an electric motor in order to make a comfortable sofa life to widen the sofa mat width to be utilized as a single bed and to make a double back of the sofa to make a thin back of the front back The present invention relates to an ondol sofa cushion which is separated from the backrest of the rear and can be converted into an ondol sofa cushion.

Families are becoming more and more nuclear families, populations are moving into aging societies, and the number of single-person households is increasing. It is true that furniture is being subdivided according to the current trend. Koreans have used traditional ondol for winter heating. However, as residential spaces become apartments, the ondol culture is applied to products in various forms.

Representatives are "stone beds" and "dirt beds" that are used to apply ondol to beds, and ondol sofas are used to apply ondol to sofas. However, it is true that Ondol sofa has structural problems and there are many things to improve.

The ondol mat is too hard for the basic seating function of the sofa, and the floor is slippery, so the user is seated and leans on his back so that his butt slips and it is difficult to fix his posture. It can be used, but it is true that it is uncomfortable because it is too cold in summer and the seating is not good.

Ondol sofas had many technical problems that had to be solved structurally even if they wanted to make the sofa wider. When widening the ondol sofa mat width, the distance from the front end of the mat to the backrest could not be used when seating. When the width of the ondol mat is narrowed, the heating part of the mat is narrow and it has been pointed out as a disadvantage in utilizing the advantages of the ondol sofa.

The existing ondol sofa was not a structural system that could simultaneously implement the function as a sofa and a single bed.

The present invention was intended to solve the above-mentioned disadvantages by simultaneously solving the function as a sofa and a single ondol bed.

The technology related to the electric sofa is a US patent that has developed the original technology, registration number 06843531 (Seating unit having horizontally positionable seat seation) and the domestic technology includes electric bed and sofa application number 20-2006-0009149.

Such technology is a driving mechanism of a two-seat sofa with a short distance to the sofa mat, in which a motor pushes and pulls the sofa mat from the center. Since such a system exerts a force on one of the bottom centers of the sofa mat, the center of gravity becomes eccentric when the heavy ondol sofa mat is pushed and pulled. It was not a structural system that could be reversed.

Therefore, in order to solve the problem, the present invention causes the power generated from the motor to generate a power action point for advancing the ondol sofa mat in two places, thereby moving the ondol sofa mat forward and backward without being influenced by eccentricity. The purpose is to make it work.

In addition, the sofa backrest can be used as both an ondol sofa cushion and a backrest, and the sofa backrest is doubled to freely convert to an ondol sofa cushion and backrest.

The ondol sofa mat, sofa frame, armrest, and backrest are modularized for each part, so it is easy to assemble and disassemble easily.

In order to achieve the object of the present invention, the motor is supplied with power from the power supply to reduce the rotation speed in the reduction gear box and increase the rotational force to rotate the time belt in the pulley coupled to the reduction gear, the lower end of the frame The male shaft rotates to transmit power to the pulleys associated with each male shaft at the end, and the female shaft coupled with the armrest and the angle penetrates while the male shaft rotates to advance the ondol sofa frame coupled with the male shaft. Try to reverse.

The second power transmission method of the above-described power transmission mechanism increases power from a motor by reducing the rotational speed of the reduction gear box and increases the deceleration torque, and transmits the power to the shaft at right angles with the right angle gear and the male shaft coupled to both ends. Power the gear to rotate the male shaft.

In the third power transmission method described above, in the second power transmission method, the right angle gear coupled to the shaft ends is rotated as a worm gear and the right angle gear coupled to the male shaft is rotated to transmit the male shaft.

The sofa back is doubled so that the sofa back can be used as a cushion for the ondol sofa mat. It is combined with the back part of the backrest so that it can be freely converted into a sofa back and an ondol sofa cushion.

A rubber magnet is inserted into the back cushion and the inner cushion material of the ondol sofa cushion to allow the sofa back and the ondol sofa cushion to be freely combined and detached.

The ondol sofa frame and the driving device are combined to form a single module, and the armrest and the backrest are each formed as a module so that movement, transportation, storage, and assembly disassembly can be easily performed.

As described above, the present invention further extends the function of sitting the ondol sofa so that it can be utilized as a single ondol bed.

Ondol sofa is equipped with a heating device on the sofa mat to warm the mat is used as a space for rest in the winter.

Such conventional ondol sofas lacked all of the functions as a function bed as a sofa. The ondol sofa mat has a wider mat than the general cushion sofa mat, and the width of the ondol mat is narrower than the width of a single ondol bed.The width of the ondol mat is wider to use as a sofa. It was difficult to slide forward and maintain a seated position. Even if the cushion was seated on the ondol sofa mat, it was as if the cushion slipped while leaning against the back.

In addition, when the ondol sofa is used as an ondol bed, the mat was not narrow enough to sleep.

The present invention can solve this disadvantage can be used ondol sofa like a general sofa and can be used by combining the ondol sofa as a single ondol bed.
