Description

Folding Recliner Sofa {Folding Easy Sofa}

The present invention relates to a folding recliner sofa. More specifically, the folding armchair, which supports the back and the head, and the part supporting the thigh and the calf, is supported by the folding body to support the human body comfortably and has a heat function to provide a comfortable rest for the user. It is about.

Bed generally refers to furniture for sleep or rest, usually in a fixed location called a bedroom. However, in recent years, a lot of folding beds that can be folded as well as easy to move in order to efficiently utilize space have been developed and used.

The folding bed is a folding frame that supports the bottom of the bed and is attached to the frame and the wheels and the frame that are attached to the frame to the legs and the ends of the legs to move the bed to a certain height from the floor to move the bed. It is common to have a mattress provided at the top of the body to support the user's body.

Meanwhile, a sofa bed combined with a sofa used for watching TV or reading or a simple rest and a bed for sleeping is also widely used. The sofa bed is used as a normal sofa in a folded state, and has a structure that can be used as a bed when it is unfolded. It is true that a sofa bed is very useful when the space is so small that it is difficult to equip both a bed and a sofa, or to provide a comfortable bed for a guest.

In the case of such a bunk bed or a sofa bed, there are also a number of foldable folding structures, and in some cases, a heating element is mounted therein to provide a heating function.

However, the conventional bunk beds or sofa bed has a disadvantage in that the emphasis on the convenience of storage and transport and the combined function of the sofa and the bed does not greatly help the user to rest and rest.

When sleeping, it is convenient to use both a rollaway bed and a sofa bed, but when reading, watching TV, or taking a simple break, it is desirable to have a function of supporting a back and raising a leg.

However, the conventional cot or sofa bed is most of those that do not have any function of supporting the back or legs, even if it is equipped with a back or leg support function, regardless of the curvature of the human body It was just enough to support the back or legs.

In particular, there are many cases of sitting on a bed or a sofa while reading, watching TV, or relaxing, but these incorrect postures cause a deformation of the spine, which injures the user's health.

The spine that connects the waist and neck of the human body is the girder of the human body. It consists of seven necks (cervical spine), 12 spines (thoracic spine), and 5 lumbar spines (lumbar vertebrae), and 12 spines have 12 The ribs of the dog are attached to the left and right to protect the internal organs. The role of the spine is to protect the spinal cord from the brain and into the vertebrae, to support weight, and to maintain a straight or correct posture, which allows the movement of our body or all physical activities to work properly and the body and the brain. It is an important organ that allows the liver to live.

Such abnormalities in the spine may cause various diseases such as muscle diseases, ligament diseases, disc diseases, bone diseases, joint diseases, neurological diseases, and organ diseases.

Therefore, in addition to the function of the conventional cot or sofa bed, which emphasizes only the utilization of the space, the cot or sofa bed with a structure that can effectively support the human body around the spine and take a comfortable rest Development was required.

On the other hand, in the case of a long time working people, people with poor kidneys or pregnant women, swollen legs and a lot of cases occur. In this case, raise your legs slightly so that blood flows well in your legs. In addition, even in patients with low back pain, lifting the legs slightly to reduce the burden on the back is also a good way to relieve pain.

By the way, even in the case of a bunk bed or a sofa bed, there were those with a structure supporting the legs. However, the conventional leg restraint structure does not support the entire leg including the thigh and the calf, and thus does not provide comfort, and in the case of supporting only the calf part, it may be unfavorable to the knee. .

On the other hand, in the conventional folding cot or sofa bed, the backrest or legrest structure has a problem that the folding structure for maintaining the backrest or legrest at a predetermined angle is complicated and inconvenient to use. In addition, the structure for maintaining the conventional folding structure at a certain angle is often protruded to the outside has a disadvantage that the appearance is not neat.

In order to solve the above problems, the present invention is formed in multiple stages to effectively support the user's spine and legs, and to freely adjust the support angle of the spine support and leg support, as well as to provide a folding recliner sofa easy to store. For that purpose.

It is another object of the present invention to provide a folding armchair that can be used as a sofa by having a separate armrest.

In addition, the object of the present invention is to provide a folding recliner sofa that can be heated by a built-in heating element, and can be released far-infrared rays and negative ions to provide a comfortable rest to the user.
