Description

[Detailed Description of the Invention] {Industrial Field of Application} The invention relates to an improvement of a water pine tress for fixing sheets used in the water pine tress.

{Prior art} Unlike conventional spring pine tresses, water pine tresses tend to deform the shape of the bag due to the movement of water under load, so they can be made with ordinary making sheets or box sheets used for spring pine tresses, etc. However, when you turn over or move around in bed, the sheets shift and roll up, especially from the corners, and the bed pads located between the waterpine tresses and the sheets also shift or swell, making it difficult to feel comfortable. The downside was that I couldn't get any sleep.

Therefore, water mattresses require special fixing devices for fixing bed pads and sheets that have rubber bands for fixing at the corners.

{Problem to be solved by the invention} As mentioned above, water pine tresses required special sheets and bed pads, but by improving the water pine tresses, it became possible to use regular sheets for use with spring pine tresses, etc. It was devised for the purpose of being able to be used with bed pads and bed pads.

{Means for solving the problem} In other words, the configuration of the present invention is to provide anti-slip sheets 3, 3', etc. with a large friction coefficient on the corner portions 2, 2',... of the surface of the rectangular bag-shaped water bag 1. It is a water pine tress characterized by being welded.

{Function} Even if the water bag 1 deforms and one corner of the water bag 1 momentarily separates from the frame due to changes in the load due to body movement such as turning over on the water pin stress, the other parts The corner part of is in close contact with the foot frame,
Due to the high coefficient of friction on the surfaces of the anti-slip sheets 3, 3', . . . on the corner portions 2, 2', . Therefore, the corner of the sheet that is momentarily separated from the frame is brought into close contact with the anti-slip sheet 3 of the corner portion 2 of the waterbag 1 by the tension of the sheet itself, and the frictional force is increased, so that no slipping occurs.

{Example} An example of the present invention will be described based on the drawings. As shown in FIG.
is formed into a rectangular bag shape made of vinyl chloride sheet, and has at least one water intake/discharge port 4.
The water bag 1 has anti-slip sheets 3, 3'... made of rubber-based polyvinyl chloride foam sheets with a high coefficient of friction on the vertical ridges of the corner parts 2, 2'... It is fixed by heat welding.

The anti-slip sheets 3, 3'... may be made of other materials as long as they have the same coefficient of friction.

Further, the surfaces of the anti-slip sheets 3, 3', . . . have irregularities 5, 5', . . . in order to increase the contact area with the sheets and increase the frictional force.

The one shown in FIG. 2 is another embodiment of the present invention, in which the size of the anti-slip sheets 3, 3'... is increased, and the corner portions 2, 2'... of the water bags 1, 1'... It is arranged from the bottom of ... to the vertical plane.

{Effect of the invention} By implementing the invention, even if ordinary making sheets or box sheets used for spring pine tresses etc. are used, the corner parts 2, 2'... of the water bag 1 can be Due to the function of the anti-slip sheets 3, 3'..., even if the water bag 1 is deformed due to changes in load due to body movements such as turning over on the water mattress, the sheets will not shift and the bed pad will remain stable. Since you don't have to move around, you can have a very comfortable night's sleep.
