Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge structure of a thick flat plate member which can be widely used for folding type bedding and rugs, sound absorbing floor materials for civil engineering and the like.

[0002]

2. Description of the Related Art A foldable mattress used as a bedding for a bedclothes is configured such that a thick flat plate member, which is a rectangular heat insulating cushion member, can be folded in a zigzag shape. As a foldable hinge structure for such a thick flat plate member such as a mattress, for example, one shown in FIGS. 8 to 10 is generally used.

The flat plate member 20 shown in FIG. 8 is a rectangular thick heat insulating cushion material or the like, and cuts 21 and 21 'are formed in the width direction at each front and back surface thereof. The two cuts 21 and 21 ′ are located at locations where the plate member 20 is equally divided into three in the longitudinal direction into the first to third plate members 20 a to 20 c. As shown by a chain line and an arrow in FIG.
The first flat plate member 20 adjacent to the notch 21 on the surface of
a is folded 180 ° on the back surface of the central second flat plate member 20b in the opening direction of the notch 21. Further, the third flat plate member 20c adjacent to the cutout 21 ′ on the back surface of the flat plate member 20 is folded 180 ° on the surface of the central second flat plate member 20b in the opening direction of the cutout 21 ′.

[0004] The flat plate member 23 shown in Fig. 9 is also a rectangular thick heat insulating cushion material or the like, and has a horizontal hole 23 formed in two places which are equally divided in the longitudinal direction. The portion of the flat plate member 22 where the lateral hole 23 exists is made thinner so that it can be easily bent from this portion. Also in this case, the flat plate member 22 is folded into a Z shape as shown by the chain line and arrow in FIG.

The flat plate member 25 shown in FIG. 10 is, for example, a rectangular flexible thick heat insulating material whose front and back surfaces are corrugated. The flat plate member 25 is configured such that the wave troughs 26 on the front and back surfaces are vertically opposed to each other, and the portion where the trough 26 is located is thinned to be easily bent. The flat plate member 25 can be folded from any of the many valleys 26.

[0006]

In the flat plate member of FIG. 8, the folding direction is fixed at the beginning of the folding work so that the folding direction can be easily bent from the notch position in the direction of expanding the notch. It requires a troublesome work to check, which makes folding work poor. Also,
If the flat member is forcibly bent in the direction opposite to the direction of closing the notch from the notch, there is a problem that the thin part having the notch may be damaged.

The flat plate member shown in FIG. 9 can be bent in any direction of the front and back surfaces of the flat plate member from the position where the horizontal hole is present. However, if you try to bend the place with the horizontal hole to the front side of the flat plate member, the back side of the flat plate member just below the horizontal hole will be pulled and it will be difficult to bend, and if you also try to bend the place with the horizontal hole to the back side of the flat plate member, the horizontal hole It is difficult to bend because the surface side of the flat plate member just above is pulled, and when the flat plate member is bent by hand from the location of the lateral hole and the hand is released, the elastic return force of the location where the horizontal hole exists causes the flat member to return to its original flat state. I had to go back, and there was a problem that folding workability was poor. Further, the flat plate member shown in FIG. 9 cannot be maintained from the flat state by bending the portion having the side hole to 180 °, and the bent flat portion is expanded and the entire flat plate member is folded in three. There was a bulky defect.

The flat plate member shown in FIG. 10 can be bent in any of the front and back directions from any of the numerous wave troughs. However, in this case, there is a problem that it is generally difficult to bend depending on the material of the flat plate member, it is not possible to bend it to 180 ° to maintain the same state, and the folding workability is deteriorated because the bent portion is not fixed. Was. Further, the flat plate member in FIG. 10 can easily form the front and back surfaces into a corrugated shape if the material is sponge or the like. There was a problem that an appropriate waveform could not be obtained, the material was restricted, and the application was limited.

An object of the present invention is to provide a hinge structure of a thick flat plate member which can be easily folded in both front and back directions and which can be applied to flat plate members made of a wide range of materials.

[0010]

According to the present invention, there is provided a hinge structure for connecting a plurality of thick plate members in a series and adjacent plate members so as to be foldable by 360 ° with respect to a counterpart. The edge portion of the adjacent flat end of the flat plate member with the front and back surfaces of the flat plate member is divided into a plurality of edge regions in the width direction of the flat plate member, and every other edge region of the edge portion on the front surface side of one flat plate member, Every other edge region of the corresponding edge portion on the back side of the other flat plate member is connected with a flexible thin sheet-like first connecting member, and the remaining edge region where the first connecting member is not connected. Every other edge region of the edge portion on the back side of the one flat plate member and every other edge region of the edge portion on the front surface side of the other flat plate member corresponding to this are formed into a flexible thin sheet-like Connect with 2 connecting materials Characterized in that was.

[0011]

The first connecting member and the second connecting member are alternately crossed and arranged side by side between two adjacent flat plate members, and one of the adjacent flat plate members is placed on the other front side or the back side. When folded toward the first connecting member and the second connecting member according to the folding direction.
One of the connecting members always exhibits the hinge function mainly, so that the adjacent flat plate members can be folded in both directions.
Further, by separating into a plurality of flat plate members and folding each through the flexible thin sheet-shaped first and second connecting members, the flat plate member can be folded by simply bending the first and second connecting members. As a result, the folding work is facilitated, and the adjacent flat plate members can be easily folded without being bulky by overlapping the front surfaces with each other or the back surfaces with each other.
