Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunctional composite sheet used for leisure purposes such as outdoor rugs and bedding, and for real life applications such as indoor rugs, bedding and interiors.

[0002]

2. Description of the Related Art As outdoor leisure activities such as camping and hiking in the sea and mountains have become popular, waterproof sheets such as thin nylon sheets have become popular as one essential item for making leisure activities comfortable. There is. This type of waterproof sheet is multipurposely used as a waterproof rug which is laid on the ground to prevent water from penetrating from the ground, a tent sheet which avoids rainwater or direct sunlight, a sunshade sheet, and the like.

However, since the above-mentioned waterproof sheet is only a thin sheet material such as nylon or polyester, it lacks heat insulation and cushioning property, and when a waterproof sheet is laid on the ground and a person sits on it, the ground is rugged. The feeling may be transmitted to the human body as it is, making it uncomfortable to sit on. In addition, when a waterproof sheet is laid on the ground with a lot of water, the cold air of the ground is directly transmitted to the human body, and such a chilly feeling is not comfortable except in summer.

Therefore, a composite sheet obtained by polymerizing a blanket on a waterproof sheet has been developed and put into practical use. This composite sheet is formed by superimposing one blanket and one waterproof sheet having the same shape as the blanket and performing helicopting on the entire circumference to integrate them. Therefore, this type of composite sheet has both the waterproof function of the waterproof sheet and the heat retention and cushioning function of the blanket, and the waterproof sheet is laid down on the ground. It is blocked by a waterproof sheet, and you can get a comfortable sitting feeling only by the feel of the blanket.

[0005]

The composite sheet as described above has a practical size of 140 × 100 cm (about one tatami) and is called a leisure sheet. It is difficult to separate the blanket and the waterproof sheet from the user side because the same shape blanket and the waterproof sheet are polymerized around the entire periphery, and when the blanket becomes dirty, the blanket is washed in a washing machine, etc. It was difficult to wash it completely. That is, if you use a composite sheet that integrates a blanket and a waterproof sheet outdoors and stains it, the dirt on the waterproof sheet can be easily wiped off with a rag, but the dirt on the blanket cannot be easily removed with a rag or a brush. It is desirable to wash it in a washing machine. However, if the blanket is washed with the waterproof sheet while the blanket is polymerized, the waterproof sheet impedes the flow of water on the blanket to extremely reduce the washing effect, and it is difficult to sufficiently clean the blanket. In addition, a composite sheet made by polymerizing a waterproof sheet of a practical size of about one tatami mat and a blanket is bulky and difficult to wash in a domestic washing machine, and as a result, the user The current situation is that composite sheets are reused while the blanket is dirty and unsanitary.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of washing the blanket of the composite sheet.
A blanket having a simple joining means on the peripheral portion of one side, and a waterproof sheet having a simple joining means which is substantially the same shape as the blanket and is detachably joined to the simple joining means of the blanket with one touch at the peripheral portion of the one side. The present invention provides a composite sheet in which both sides having the simple joining means are aligned and the simple joining means are joined to each other so as to be removably polymerized.

Here, as the simple joining means for the blanket cloth and the simple joining means for the waterproof sheet, a pair of male and female buttons and hook-and-loop fasteners which are joined and released with one touch are suitable. It is fixed by stitching or the like at a plurality of positions at predetermined intervals on the peripheral edge. Such a composite sheet obtained by polymerizing a blanket and a tarpaulin is used as a rug on the ground, a sunshade sheet, a rainbreak sheet, or a single bed incontinence, bedwetting countermeasure sheet, etc. If the need arises, the blanket and tarpaulin are separated.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A composite sheet 1 of the embodiment shown in FIG. 1 (A) is formed by detachably polymerizing a blanket 2 and a waterproof sheet 3 having the same shape. The blanket 2 is a cotton blanket, a wool blanket, an acrylic blanket, a blended cotton blanket such as acrylic, and the like.
The vertical and horizontal sizes are, for example, 140 x 100 cm (about the size of one tatami mat). The waterproof sheet 3 is a nylon sheet, a vinyl chloride sheet, a polyethylene sheet or the like having the same size as the blanket 2.

In the present invention, as shown in FIG. 1 (B), the simple joining means 4 is provided at a plurality of positions on the back surface of the peripheral portion of the blanket 2.
Is fixed, and the simple joining means 5 that is detachably joined to the simple joining means 4 of the blanket 2 with one touch is fixed at a plurality of positions on the back surface of the peripheral edge of the waterproof sheet 3 with respect to each other. Simple joining means 4, 5 for joining the blanket 2 and the waterproof sheet 3
1 is a pair of male and female buttons (dot buttons, etc.) and a pair of male and female surface fasteners, which are commonly called magic tapes, are suitable, and the buttons are shown in FIG. The simple joining means 4 is fixed to the blanket 2 by suturing and the simple joining means 5 is fixed to the waterproof sheet 3 by welding, but these fixing forms are not limited.

As shown in FIG. 1 (A), the back surfaces of the blanket 2 and the waterproof sheet 3 are overlapped with each other and the simple joining means 4, 5 for both are put together.
By pressing each other and joining them with one touch, 1
A composite sheet 1 is formed. The composite sheet 1 can be used in a wide variety of applications, and representative examples thereof will be described with reference to FIGS. 2 to 4.

FIG. 2 shows an application as a rug in which the composite sheet 1 is spread and laid on the ground 6 in the open air. In this case, the composite sheet 1 is used with its waterproof sheet 3 facing down,
A person sits on the blanket 2 that is on top. In this case, the moisture from the ground 6 is blocked by the waterproof sheet 3 and does not penetrate into the blanket 2, so that the blanket 2 is not wetted with water or soiled, and people or objects on the blanket 2 are No need to worry about getting wet or dirty with soil. In addition, since the blanket 2 has a heat retaining property and is superior in cushioning property to the waterproof sheet 3, the rugged feeling that a person sitting on the blanket 2 receives from the ground 6 is mitigated by the blanket 2 and the composite The seat 1 is comfortable to sit on.

FIG. 3 shows an application in which the composite sheet 1 is used as a tent sheet and an awning sheet for avoiding rainwater and direct sunlight. For example, four columns 7 are erected on the ground 6, and the four corners of the composite sheet 1 are hooked on the upper ends of the columns 7 and stretched diagonally. In this case, with the waterproof sheet 3 facing up, the composite sheet 1
By stretching, the composite sheet 1 exerts both the function of the rain and the function of the sun. In order to facilitate the work of attaching the composite sheet 1 to the support column 7, a mounting hole (not shown) through which the support column 7 and the sheet tensioning rope are inserted and hooked at important points including the four corners of the composite sheet 1. It is also possible to previously form).

FIG. 4 shows an application in which the composite sheet 1 is used for the sheets of the single bed 8. This composite sheet 1
Is used as a bed sheet for measures against nocturnal enuresis of infants or incontinence measures for elderly persons, and is laid on the single bed 8 with the waterproof sheet 3 facing down. In this case, a person sleeps on the blanket 2 and can sleep with a good feel and heat retention on normal blanket sheets. Even if moisture such as urine permeates the blanket 2, the permeation of water is blocked by the waterproof sheet 3 and the single bed 8 does not become dirty.

In the use of the composite sheet 1 described above, when the blanket fabric 2 becomes dirty, the blanket fabric 2 may be separated from the waterproof sheet 3 and washed as shown in FIG. 1 (B). The blanket 2 separated from the waterproof sheet 3 is not bulky, and can be easily washed with a washing machine in a general household, and cleanly in every corner. On the other hand, in the waterproof sheet 3 separated from the blanket 2, the front and back surfaces thereof are wiped with a rag to remove dirt. The composite sheet 1 in which the blanket 2 washed in this way and the waterproof sheet 3 that has been cleaned up to the front and back are united again,
It is reused after being cleaned both inside and outside, so that it looks like a new product with excellent appearance and hygiene.

Further, in the blanket 2 and the waterproof sheet 3 separated as shown in FIG. 1 (B), it is possible to use each of them individually if necessary. As an example of such a single use, for example, when the blanket 2 is used as a rug on a sunny day and the waterproof sheet 3 is used as an awning sheet, or in a tent, the waterproof sheet 3 is used as a rug and the blanket 2 is applied to a human body. This is the case when it is used as a hanging object.

[0018]

According to the present invention, even if the composite sheet obtained by polymerizing the blanket and the waterproof sheet becomes dirty, the blanket and the waterproof sheet can be easily separated from each other. Therefore, only the blanket should be washed in a washing machine. Since the waterproof sheet can be easily washed and the composite sheet can be washed independently, users of the composite sheet can wash it when it is dirty and reuse it as clean and hygienic as new. This makes it easier to do this, further increasing the commercial value of the composite sheet.

Further, since the blanket and the waterproof sheet can be easily separated, it is possible to divide the composite sheet into the blanket and the waterproof sheet and use each independently, and it is possible to easily change the function and to have more functions. We can provide a versatile composite sheet that is convenient for both outdoor activities and indoor activities for users.
