DETAILED DESCRIPTION OF THE INVENTION

[0101]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress structure in a pocket coil mattress which allows a spring to be rearranged.

[0092]

2. Description of the Related Art Conventionally, as a pocket coil mattress, a coil spring is sealed in a large number of continuous bags, and a continuous spring row is meandered to form a rectangular spring seat. Are fixed by tightening with a string, or a stable spring sheet is obtained by bonding, a padding is fixed to the upper and lower surfaces of the spring sheet, and the entire body is covered with an exterior body to form a mattress.

In the case of the pocket coil mattress as described above, the spring sheet is formed integrally, and the whole is hermetically covered with an outer package to form an integrated mattress. Although it was possible to make a mattress with different elastic characteristics in the area, the spring could not be changed according to the weight and body shape of the sleeper.

[0093]

The problem to be solved by the present invention is to make it possible to change the spring so that a comfortable sleeping posture and sleeping comfort can be obtained according to the weight and body shape of the sleeper. .

[0056]

A plurality of pocket spring assemblies (2) (2 ') having the same size as the rectangular cushion frame (1), and an openable / closable outer body (3). And the pocket spring assembly (2).
(2 ′)... Are provided with pocket elastic assemblies (2) (2 ′)... Having different elastic characteristics in a rectangular cushion frame (1).
This is a spring-combinable mattress that is selectively housed and covered with an exterior body (3) that can be freely opened and closed.

[0086]

According to the present invention, the exterior body (3) is openable and closable, and the pocket spring assembly (2) (2 ')
··································································································· are provided with pocket spring assemblies (2) (2 ′). The mattress cushion characteristics can be selected according to the weight and body shape of the person sleeping.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the cushion frame (1) is a frame made of rectangular urethane foam. ), A rectangular felt sheet (4) is bonded and fixed to the lower side to form an accommodating portion of a box-shaped pocket spring assembly (2) (2 ′)...

The upper and lower mirror portions (5) of the exterior body (3) are quilted integrally by filling a cushion material (8) such as cotton or urethane between a surface material (6) and a lining (7). A fastener (10) is provided on the upper end of the surrounding gore (9) and the outer periphery of the upper mirror (5), and the exterior body (3) can be freely opened and closed.

A felt sheet (4) is adhered and fixed to the surface of the lining (7) of the mirror part (5) on the upper side of the exterior body (3).

As shown in FIGS. 3 and 4, the pocket spring assembly (2) has a pocket coil (12) sealed in a plurality of continuous bags (11). Three rows constitute one pocket spring assembly (2), and adjacent spring rows (13)
(13 ') One pocket spring assembly (2) connected at the center in the height direction by hot melt bonding
Is formed. The pocket spring assembly (2) does not limit the number of the spring rows (13) to three rows, and the pocket spring assemblies (2) (2 ′)... Have the same size. Good.

This pocket spring assembly (2)
(2 ′)..., As shown in (a) to (d) of FIG. 5, (a) is a pocket coil (12) having the same wire diameter, and (b) is a pocket coil. The combination of (12) having different wire diameters, (C) is a combination of a polyurethane foam (14) formed by injecting a polyurethane foam liquid into a bag (11) containing a pocket coil (12), and (D). )
Is an example of a combination of (b) and (ha), and a pocket spring assembly (2) (2 ′) having different elastic properties.
., And having different elastic characteristics of the pocket spring assembly (2), (2 ′)..., Or by changing the insertion position. Mattresses that match the weight and body shape can be easily formed.

FIG. 6 shows another embodiment of the present invention in which the present invention is applied to a wide type mattress that can sleep two people. 2) The length of the mattress is short so that it can be accommodated in two rows in the width direction of the mattress, and the cushion characteristics can be selectively rearranged on the left and right in the width direction according to the person sleeping.

[0113]

According to the present invention, it is possible to easily select or rearrange pocket spring assemblies (2) (2 ')... Having different elastic characteristics according to a person who sleeps. Optimum cushioning characteristics can be achieved.
