Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress using a pocket coil spring, and more particularly to a mattress using a pocket coil spring, which is excellent in independent suspension as a pocket coil, and is capable of disassembling a coil, a padding, a dress material, and the like. The present invention relates to a mattress for facilitating washing, drying, disposal, etc.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 5, a mattress using a pocket coil spring has spring coils put in individual bags and connected to each other. A net is stretched around the frame line, and the bag of the coil is fixed with many nails.

Further, a padding made of a material such as felt or urethane and an inner cloth of the outer material are fixed to a frame line with a large number of nails on the net to form an integral body as a whole.

[0004]

However, depending on the above-mentioned structure, there are the following problems. (A) If a net and a padding are stretched over a steel frame, when a load of a human body is applied to the net or padding, the steel frame is reduced to one point. The applied force becomes a kind of trampoline-like structure that the nets stretched over the frame take as a surface, and as a result, each coil absorbs the partially applied load independently. This reduces the independent suspension of a so-called pocket coil spring having the characteristics described above, and causes a loss of cushioning. (B) Further, the mattress in which each of the above elements is integrally formed is extremely difficult to disassemble, and cannot be dried or washed on the way.
The inside that is dirty and absorbs moisture is easily contaminated with bacteria, and the surface material and fillings cannot be replaced. (C) In the case of aging and disposal, 200 to 3
A mattress with 00 nails fixed with an air gun requires the nails to be manually removed one by one, which is a difficult task requiring enormous amount of time and labor, and a large amount of waste is discharged. Was a problem. The present invention has been made to solve the above-mentioned drawbacks.

[0005]

According to the mattress of the present invention, a coil layer is formed by fixing an adjacent portion of a pocket bag enclosing a coil and covering the entire portion with a cloth having some elasticity to form a coil layer. Two or more paddings are covered with a cloth having a slight elasticity, and the periphery thereof is bordered to form a padding layer. A fixed belt attached to the border with the coil layer interposed between the upper and lower padding layers. The contents obtained by combining the three members are loaded into a sewing bag formed by stitching the lower mirror and the side ground, and a zipper is applied between the sewing bag and the upper mirror. The contents can be taken out easily.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The mattress of the present invention comprises a coil layer 10 on which pocket coils are arranged, a padding layer 20 in which padding is integrated, and a surface material 30 that encloses the padding layer. First, the conventional frame is not used for the coil layer 10. Then, as shown in FIG. 2, the barrel-shaped coil 11 is put into each bag body 12 to form a pocket coil spring, and the bag bodies 12 are connected in series in the lateral direction.
It is also fixed in the vertical direction by hot melt adhesive, etc., that is, the adjacent parts where the bags contact each other are connected to each other,
Coupling between coils.

Next, the entire pocket coil is covered with a shaping cloth 13 having a slight elasticity, and its material is, for example, a knitted cloth woven or knitted. this is,
This is to wrap the entire coil enclosed in the bag to help form a shape without a frame line, and to be able to follow deformation from external pressure.

Next, as shown in FIG. 3, the filling 21 is covered with a cloth 22 having a slight elasticity similarly to the above-mentioned shaping cloth, and a periphery 23 is provided around the filling 22 to form a filling layer 20 which is integrated as a whole. I do. The padding 21 may be a stack of two or three sheets of felt, urethane, or the like, or may be a single sheet, and is determined in consideration of hardness, moisture absorption, and the like. Then, as shown in FIG. 4, the upper and lower filling layers 20a, 20b
Are arranged above and below the coil layer 10 and the padding layer 2
Fixing belts 24a, 24b are attached to the borders 23a, 23b provided around the periphery of 0a, 20b. That is, the stuffing is further increased to achieve integration, and the fixing belt 24 is provided therebetween.
a, 24b to form a structure capable of compensating for the amorphous nature of the pocket coil without the frame line and maintaining the form stability. Although the form of the fixing belt 24 is shown as tying a cord body in the drawing, the present invention is not limited to this, and a tangled piece, a hook, or the like may be provided at the end of the cord.

Further, as shown in FIG. 1, a lower mirror fabric 31 and a side fabric 32 as a surface material are sewn together, and a sewing bag 33 is formed in a form in which the contents obtained by combining the three members can be completely enclosed. Then, the upper mirror 34 is put on the opened upper surface, and a fastener 35 is interposed between the upper mirror 34 and the sewing bag 33 so that the contents can be taken out. The sewing bag 33 formed by stitching the lower mirror fabric 31 and the side fabric 32 is for stably storing the contents, and the interposition of the fastener 35 is such that the upper surface is opened and the coil layer 10 and the filling layer 20 are opened. This is to make it possible to take out the contents and to improve the decomposability during washing, drying and disposal in the middle.

Next, the operation of the present invention will be described. In the mattress of the present invention, the inherent independent suspension of the pocket coil is first enhanced by eliminating the frame line. That is, as shown in FIG. 5, in a conventional pocket coil provided with a frame, a load is applied to a pad such as a net and a felt since the padding such as a felt is stretched over the frame having a metal rigidity by nailing. In this case, the stretched surface receives the load as a whole, and the bending is distributed and transmitted to the lower pocket coil. Therefore, it becomes a cause of impairing the original independent suspension of the pocket coil. However, in the mattress of the present invention, since the frame line is not used at all, even if a person with severe irregularities such as shoulders and waist is supine, the load is directly transmitted to each pocket coil, and The coils independently absorb body pressure.
Therefore, the independent independent suspension of the pocket coil can be increased, the ideal natural posture can be maintained, and the vibration isolation property can be increased.

Next, the instability of the form naturally occurs due to the elimination of the frame line. On the other hand, (a) the adjacent pockets are connected to each other and the whole is covered with a shaping cloth having a slight elasticity to integrate the pocket coil (see FIG. 2), and (B) the padding is further increased. In addition, since the contents are integrally formed by connecting the fixed belt on the upper and lower sides with the pocket coil interposed therebetween, it is possible to deepen the connection in cooperation with each other (see FIG. 4), and to reduce the instability of the above-described embodiment. Overcome.

In addition, when the user sits down on a bed instead of a sofa, the frame line hits the thigh, causing a feeling of foreign matter on the skin. However, the mattress of the present invention does not have this, so that a soft feel can be enjoyed. It will be comfortable.

Next, the sewing bag 33 and the upper mirror fabric 34 are joined with a fastener 35, and the upper side is opened to open the coil layer 10
The stuffing layer 20 can be taken out (see FIG. 1), and can be separated from each other by removing the fixing belt 24, so that the stuffing layer 20 can be washed and dried (see FIGS. 3 and 4). In particular, the stuffing absorbs sweat while sleeping,
In addition, it is easy to get dirty due to leakage of demented elderly people and children, and there is concern about bacterial contamination. However, washing and drying will solve this problem. Further, in a bed for business use in a hotel, a hospital, or the like, since a bed used by another person is used repeatedly, it is desirable to wash the dress material, padding, and the like at regular intervals, and this washing can be performed.

Further, it is possible to partially replace the outer material, the stuffing, etc., and when the outer material, the stuffing, etc. are partially damaged, they can be partially replaced and repaired to make the durability life permanent. it can. Also, since the fillings have a wide range of elasticity,
There are cases where the user prefers to be hard and those who prefer to be soft. In general, there is a tendency to prefer a soft material with aging, so that the stuffing can be exchanged according to one's own preference.

[0015] Thus, when discarding after the end of its useful life, the conventional mattress is 200 to 3
Since about 00 nails had been hammered out, it was necessary to remove and disassemble the nails one by one, which was extremely severe labor. However, since the mattress of the present invention does not use the nails, there was no need for this work. . Further, if the fastener 35 is opened and the fixing belt 24 is removed, the coil layer 10 and the filling layer 20 can be easily disassembled, so that the metal coil can be separated from the bag and reused. Can be incinerated as it is. Furthermore, by separating the aged ones from those that have not progressed relatively far and partially replacing only the aged ones, it is possible to contribute to the reuse of other parts, and to reduce the amount of waste. Is reduced to a minimum.

[0016]

Since the mattress of the present invention based on the above-described structure and operation does not use any frame lines, even if it hits the shoulder or the waist, each pocket coil absorbs it and the sleeping posture of the person. It fits the body shape and demonstrates the original independent suspension, and can exhibit excellent cushioning properties. At that time, the pocket coil in which the adjacent pockets were connected to each other was covered with a shaping cloth having a slight elasticity, and the padding was further increased and the fixing belt was connected up and down. However, they can cooperate with each other to maintain the form stability. In addition, a zipper is interposed between the outer fabric and the upper mirror to take out the filling and the pocket coil, and furthermore, the fixing belt is removed so that they can be separated from each other, so that the filling and the outer fabric can be washed and dried. , Bacterial contamination and the like can be avoided. Furthermore, at the time of disposal,
Since there is no nail removal work, dismantling work can be greatly reduced, and excellent effects such as reusing coils etc. and incineration of only the minimum amount are effective in contributing to effective use of resources. To play.
