A sofa where you can comfortably lie down on your side.

Abstract

When lying on your side on the seat of a sofa, if you rest your elbow on the seat and support the side of your head with your palm, your hand will become numb or tired if you keep your elbow on the seat and support your head with your palm for a long time. Also, in this position, you cannot use the arm on the side where your elbow is resting, and you can only use the arm on the other side, which is inconvenient. [Solution] In this invention, in a sofa having a seat and armrests on both the left and right ends of the seat, the seat is cut out from the front at two points on the left and right of the part of the seat that contacts the armrest, or at two points on the left and right near the armrest. As a result, when lying on one's side with either the left or right armrest as a pillow, the part of the seat that touches the shoulder is cut out, so that weight is not placed on the shoulder, making it possible to lie on one's side comfortably for a long time.

Description

Technical Field

[0001] The present invention relates to a sofa or cushion that can be comfortably reclined horizontally for a long time.

Background Art

[0002] Many people lie down on the sofa to watch TV and relax. However, when trying to watch the TV located opposite the sofa while lying horizontally on the sofa seat surface, one has to lie down horizontally. At that time, since the head is unstable, it is often the case that one props the elbow on the seat surface and supports the side of the head with the palm. In that case, if one props the elbow and supports the head with the palm for a long time, the hand may become numb, the shoulder may become stiff, and one may easily get tired. Also, in this state, the arm on the side where the elbow is propped cannot be used, and only the arm on the opposite side can be used for tasks such as picking up snacks, which is extremely inconvenient. Furthermore, when playing video games in a reclined state, both hands cannot be used, which also causes extreme inconvenience. Also, there are cases where one does not support the head with the hand but places the head on the sofa armrest, a pillow, a cushion, etc. However, in existing sofas, there are no sofas specialized for lying horizontally, and they often do not have the right height. Also, even when placing the head on the armrest, a pillow, a cushion, etc., when lying horizontally to watch TV, since the weight is applied to the shoulders, which are the widest part of the human body in width, and the arm located under the body, if one spends a long time in this state, the shoulders will become sore and the arms will become numb, etc., imposing a burden on the body and making it impossible to lie horizontally comfortably for a long time. Also, the inability to move the arm under the body is the same as the case of propping the elbow. Therefore, in the prior art, it is known to reduce the load on the shoulders by using a more flexible low-rebound material for the cushioning material at the shoulder position when lying horizontally.

[0003]

Patent Document 1

[0004] However, Patent Document 1 reduces the burden on the shoulder by using a more flexible, low-rebound material for the cushioning material that is located at the shoulder when lying on one's side. However, even though it is low-rebound, the cushioning material is in contact with the shoulder and arm, so there is still some burden on the shoulder, and it has the drawback that the arm cannot be moved freely. When lying on your side on the seat of a sofa, if you rest your elbow on the seat and support the side of your head with your palm, your hand will become numb or tired if you keep your elbow on the seat and support your head with your palm for a long time. Also, in this position, you cannot use the arm on the side where your elbow is resting, and you can only use the arm on the other side, which is inconvenient. Furthermore, even when resting one's head on an armrest, pillow, or cushion instead of using one's hands, existing sofas often have unsuitable heights. Also, when sleeping on one's side, weight is concentrated on the shoulder, the widest part of the human body, and the arm located beneath the body. Spending extended periods in this position can cause physical strain, such as stiff shoulders and numb arms, making it impossible to comfortably sleep on one's side for extended periods. Additionally, the inability to move the arm beneath the body is the same as when resting one's elbow on a surface. Furthermore, while Patent Document 2 reduces the burden on the shoulders by creating a concave step in the shoulder area, the left and right convex parts of the concave area are connected at the base, so increasing the depth of the concave area also increases the height of the base, resulting in a higher overall height. Also, as is common to Patent Document 1, since there is only one pillow area, when lying on one's side with the television positioned in front of the body, it can only be used in one direction, either facing right or left. Patent Documents 1 and 2 are inventions relating to cushions, and since they are relatively lightweight, one can rotate the cushion 180 degrees to use it in the opposite direction. However, for items like sofas, which are not meant to be rotated once they are set up, rotating them 180 degrees during use is very inconvenient. Furthermore, a common feature of Patent Documents 1 and 2 is that the height of the pillow portion and the height of the cushion portion that supports the body cannot be changed, making it impossible to fit people of all ages and genders with various body types. [Means for solving the problem]

[0005] Therefore, in the present invention, in a sofa having a seat, armrests on both ends of the seat, and a backrest, or a sofa having a seat, armrests on both ends of the seat, and no backrest, the seat is cut out from the front side, leaving a portion of the seat intact, at two points on the left and right of the part of the seat that contacts the armrest, or at two points on the left and right near the armrest, or the seat that contacts the armrest, or the seat near the armrest, is cut out from the front to the back, so that when lying on one's side with either the left or right armrest as a pillow, the part of the seat that touches the shoulder is cut out, so that weight is not placed on the shoulder, and thus it is possible to lie on one's side comfortably for a long time. When a person lies on their side, their body is supported by the side of their body, from the temple of their head and armpit down to their buttocks and feet. Their arms are suspended in the air, and if left hanging loosely, they may touch the floor, depending on the height of the sofa seat. If you are uncomfortable with your arms touching the floor, you can add a cushion or something similar under the seat to rest your arms on. The width of the seat cutout should ideally be equal to or greater than the distance from the base of a person's neck to their armpit, with a little extra room to spare. However, if the notch is too wide, a part of the body will have to support the weight, putting a greater strain on the body. Therefore, it is desirable that the notch is not too wide, but still has enough room for the arm to pass through it and relax. Furthermore, the difference in height between the armrest (which serves as a pillow) and the seat should ideally match the difference in height between the armpit and the side of the head when lying on one's side. However, since this height difference varies from person to person, it is desirable that the height of either the armrest or the seat be adjustable. [Effects of the Invention]

[0006] By using the sofa of the present invention, people of all ages and body types can support their heads with the armrests and their sides below the armpits with the seat, whether lying on their right or left side. This allows them to rest their weight without putting pressure on their arms and shoulders, which are located on the underside of their bodies when lying on their sides, making it possible to watch television in a comfortable position for extended periods. Furthermore, by ensuring a wide range of motion for the arms located on the underside of the body when lying on one's side, the arms can be used freely, allowing for more comfortable lying on one's side for longer periods.
