Abstract

(57) [Problem] To provide a mattress core material which is free from sinking due to weight during use, has high air permeability, and does not cause unevenness. SOLUTION: A plurality of projections are arranged in rows and columns at equal intervals and protrude on one surface of a substrate without bending deformation, and adjacent columns or rows of projections are shifted from each other by a half pitch to shift their positions. On a portion where no projection is provided, two core members provided with ventilation holes at a pitch of 1/2 of the pitch of the projections arranged vertically and horizontally are overlapped with the tops of the projections attached to each other. Thereby, bending resistance and air permeability were improved.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a mattress core.

[0002]

[Prior art]

 In bedding such as mattresses, it is necessary to disperse the weight and transmit it to the mattress, etc., so that the weight does not concentrate on the mattress facing a specific part of the body when supporting the weight. Some measures have been taken to vary the strength of the springs depending on the installation position.

[0003] However, it is difficult to support the weight according to the body shape, and there are unsatisfactory points such as the lowering of the waist at bedtime. In addition, since the mattress itself is also an aggregate of springs, it must be large enough to cover the area of one sleeping person. There was a thing.

[0004]

[Problems to be solved by the invention]

 In view of the above, an object of the present invention is to provide a mattress core material which is free from sinking due to weight during use, has high air permeability, and does not cause unevenness.

[0005]

[Means for Solving the Problems]

 A plurality of projections are arranged in rows and columns at equal intervals on one surface of the substrate without bending deformation, and the projections of adjacent columns or rows are shifted by half a pitch from each other to form projections on the substrate. In the part that is not provided, two cores having ventilation holes provided at a pitch of one half of the pitch of the protrusions arranged vertically and horizontally are overlapped with the tops of the protrusions attached to each other. Bending resistance and air permeability were improved.

[0006]

[Embodiment of the invention]

 An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a substrate having a size corresponding to the size of the mattress or a size obtained by dividing the mattress into two or three, and a plurality of projections 2 are arranged on one surface thereof at equal intervals in rows and columns. Protrude.

The projections 2 have a columnar shape with a rectangular cross section, are all at the same height, and the top 3 is a flat surface. The projections 2 are arranged at equal intervals in each row as shown in the drawing, and the vertical or horizontal rows of the projections 2 are shifted from each other by half a pitch between adjacent columns or rows. In portions of the substrate 1 where the projections 2 are not provided, ventilation holes 4 are provided at a half pitch of the pitches of the projections 2 arranged vertically and horizontally.

The core material 5 having the above structure is overlapped so that the flat surface 6 of the substrate 1 is the outer surface, the protrusion surface 7 from which the protrusion 2 protrudes is the inner surface, and the tops 3 of the protrusions 2 on the protrusion surface 7 are in contact with each other. . By doing so, the two substrates 1 are positioned in parallel with an interval corresponding to twice the height of the projection 2. At this time, the air holes 4 provided in each of the two substrates are seen to overlap and penetrate the core material 5 vertically, and the space existing between the projections 2 is connected to the air hole 4.

The core member 5 is made lightweight by molding a synthetic resin or the like, but is not easily bent and deformed.

When the core material of the present invention is used, as described above, the protruding surfaces 7 of the two core materials 5 abut each other, and the flat plate surface 6 is overlapped with the outer surface. A cushion material layer having a property is provided, and the outermost layer is covered with side lands to finish the mattress.

According to the above configuration, in the mattress using the core material 5 of the present invention, the core material 5 at the center of the mattress does not bend and deform, so that even if a load is applied to a specific position, the portion is depressed. It is possible to sleep in a stable posture without any trouble.

In addition, moisture, heat, etc., which have entered the mattress during bedtime pass through the gap between the two substrates and escape to the outside through the ventilation holes, so that it can be used comfortably without occurrence of unevenness. come.

[0014]

[Effect of the invention]

 Since the core material of the present invention has no bending deformation, when used as a mattress core material, even when a load is applied to a part thereof, the portion at the time of sleeping is stable without being depressed only at the portion. Due to the gap between the two substrates, it has excellent air permeability and does not show any unevenness during use of the mattress.
