Description

  The present invention relates to a mattress device having a main body formed of an elastic material such as urethane foam.

  Generally, a bed apparatus has a bed frame, a floor board is provided on the bed frame, and a mattress apparatus is placed on the upper surface of the floor board. There are various known mattress devices, and one of them is an exterior body in which a body portion formed by an elastic material such as urethane foam so as to have a rectangular planar shape is sewn in a bag shape. The one housed in the housing is known.

  According to the mattress device having the above configuration, the main body portion has uniform hardness, that is, cushioning property throughout. For this reason, when the user lies on the top surface of the mattress device, heavier parts of the body such as the buttocks and lower backs sink more than other parts, which may cause a decrease in sleeping comfort.

  Therefore, by forming the main body part with a plurality of elastic materials having different hardness along the longitudinal direction, the heavy part of the body sinks more greatly than the other part of the user lying on the main body part. A mattress device has been developed that can be supported so that there is no such thing.

  However, according to such a configuration, since the main body is formed of a plurality of elastic materials having different hardness along the longitudinal direction, if the physique such as the height and weight of the user is different, the heavy part of the body May not be supported by a portion of the main body portion formed of a hard elastic material.

  In addition, the hardness distribution state of the main body cannot be changed depending on the difference in the user's physique, preference, or whether the sleeping posture is on the back or on the side.

  Accordingly, a plurality of insertion grooves each having a reverse T-shaped cross-section in the longitudinal direction of the main body portion are provided at predetermined intervals along the width direction of the main body portion having a rectangular planar shape formed of an elastic material. In addition, by selectively inserting an adjustment material with a different hardness, which is formed in a cross-sectional shape corresponding to the cross-sectional shape of the insertion groove, the hardness of the main body can be adjusted according to the user's physique and sleeping posture. Mattress devices that can change the distribution state have been developed.

  By the way, the said main-body part and the said adjustment raw material are normally formed of elastic materials, such as a urethane foam. This type of elastic material has a high surface friction coefficient, and the surface is easily damaged by friction.

  Therefore, when the adjustment material is inserted into the insertion groove formed in the main body, one end in the longitudinal direction of the adjustment material is inserted through the one end opening in the longitudinal direction of the insertion groove and pulled into the insertion groove. Then, the adjustment material is not easily mounted on the insertion groove, and the adjustment material may be damaged. Similarly, when the adjustment member inserted into the insertion groove is replaced with one having a different hardness, it may be difficult to remove the adjustment member from the insertion groove.

  The insertion groove has an opening groove portion opened over the entire length in the width direction on the upper surface of the main body portion. For this reason, it is conceivable that the adjustment material is elastically deformed and pushed into the insertion groove from the opening groove, or the attached adjustment member is removed.

  However, the adjustment material must be elastically deformed and pushed into the insertion groove, or the adjustment material mounted in the insertion groove must be elastically deformed and taken out. Not only is the attachment / detachment of the material not easy, but the adjustment material may be damaged.

  That is, conventionally, although there is a mattress device that can adjust the distribution of hardness of the main body according to the physique of the user, the hardness of the main body can be adjusted easily and quickly. A component was not developed.
