JP3083135U - Cushion with water bag - Google Patents

Abstract

(57) [Abstract] (with correction) [Problem] A conventional cushion having a water bag has a two-layer structure and is not preferable as a pillow because body temperature is exposed.
In addition, there was a disadvantage that the feel was poor. SOLUTION: In the cushion with a water bag of the present invention, the cushion comprises a lower layer 2, an intermediate layer 3, and an upper layer 4.
The lower layer is a water bag 5, the intermediate layer is a heat insulating material 6 surrounding the lower layer, the upper layer is a cushion material 8, the plane size of the lower layer is smaller than that of the upper layer, and the center of other layers is substantially the center. Part. The width of the lower space is made larger than that of the upper space where the lower layer is not located.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a cushion with a water bag, particularly a cushion such as a pillow or a cushion with a water bag capable of dispersing body pressure.

[0002]

[Prior art]

 Conventionally, for example, a water pillow disclosed in Japanese Utility Model Laid-Open Publication No. 6-222 is known.

[0003]

[Problems to be solved by the invention]

 However, in the conventional water pillow described above, the pillow has a two-layer structure of an inner layer and an outer layer, the inner layer is a water layer, and the outer layer is a pillow material layer such as buckwheat hulls.The inner layer and the outer layer have the same size. Because they are vertically stacked, they cannot be deformed even when subjected to body pressure, that is, they are extremely inconvenient to use and have a bad touch as other ordinary water pillows because they cannot disperse body pressure. Was.

As a result of various experiments and studies, the inventor of the present invention has a three-layer structure including a lower layer filled with water, an intermediate layer of a heat insulating material, and an upper layer of the cushion material. It has been found that the above-mentioned problem can be solved by reducing the size and by placing the layer in the approximate center of another layer. The present invention has been made based on such knowledge.

[0005]

[Means for Solving the Problems]

 The cushion with a water bag of the present invention has a three-layer structure of a lower layer, an intermediate layer, and an upper layer, wherein the lower layer is a water bag, the intermediate layer is a heat insulating material surrounding the lower layer, and the upper layer is a cushion material. The lower layer is characterized in that the plane size of the lower layer is smaller than that of the upper layer, and the lower layer is located substantially at the center of the other layer.

[0006] An aluminum vapor-deposited film is formed on the outer periphery of the heat insulating material.

Further, the lower layer is characterized in that the width of the lower space is larger than that of the upper space where it is not located.

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

In the present invention, as shown in FIGS. 1 and 2, for example, a flat cushion having a length, width and height of 50 cm, 70 cm, and 15 cm, for example, a pillow 1 is formed by lower layer 2, middle layer 3 and upper layer 4. The lower layer 2 is a water-tight water bag 5 made of vinyl or the like for holding water, and the opening provided on the lower surface of the water bag 5 is closed with a plug (not shown). The layer 3 is composed of a heat insulating material 6 such as a nonwoven fabric surrounding the water bag 5 and an aluminum vapor-deposited film 7 attached to the outer periphery thereof, and the upper layer 4 is composed of a cushion material 8 such as feathers, wool, polyester cotton and the like. And

The lower layer 2 has a sufficiently smaller plane size than the upper layer 4, and is positioned substantially at the center of the other layers 3 and 4 when viewed from the plane. The spaces 1a, 1b, and 1c where the lower layer 2 is not located are formed on the right side. Preferably, the width of the upper space 1a and the left and right spaces 1c is 5 cm, and the width of the lower space 1b is 13 cm.

Since the cushion with a water bag of the present invention has the above-described configuration, a soft touch can be obtained as compared with a conventional pillow, and the body temperature is reduced by the lower layer 2 because the intermediate layer 3 functions as a heat insulating material layer. As shown in FIG. 3, when the human head 9 is placed on the pillow 1 in the use state, the head and shoulders are placed on the lower space 1b where the lower layer 2 made of water is not arranged. Therefore, the height of the pillow 1 can be arbitrarily changed by adjusting the amount of water in the lower layer 2 so that the pillow can be completely adapted to the user.

[0012]

[Effect of the invention]

 As described above, according to the cushion with a water bag of the present invention, the pillows have a three-layer structure with different feels, so that not only an excellent feel that cannot be obtained with a conventional pillow but also an arbitrary height can be obtained. It has the great advantage that a great sense of stability can be obtained because the body pressure can be dispersed.

The present invention can be similarly applied to a cushion.
