Abstract

The tube according to the present invention comprises: an upper sheet which has the shape of a cross and forms the upper part of the tube; a lower sheet which has the shape of a cross and forms the lower part of the tube; an internal sheet attached to both the central inside surface of the upper sheet and the central inside surface of the lower sheet and thereby holds the central part of the tube such that the central part of the tube does not swell when air is injected; a gripping means for providing grip, obtained by forming holes in upper, lower, left and right protuberances of the upper and lower sheets; and a junction part at the edges of the upper and lower sheets, the junction part being obtained by a process of sealing by high frequency heat so as to seal the tube. The present invention can be used variously including not only as a water toy but also as a pillow or cushion. Also, convenience of portability is improved due to the formation of the grips. Also, tubes may be constituted in such a way as to be connectable with each other so as to produce combined tubes of various shapes and sizes.

Description

tube

TECHNICAL FIELD The present invention relates to tubes, and more particularly, to tubes used for swimming or cushions and pillows.

In general, the tube is shaped like a rubber tube inside a car tire, and is used for the safety of a swimmer who is poor. The conventional tube is a donut-shaped tube, the air is injected into the tube body is formed, the through-hole is formed in the center of the tube body so that the user's body can enter the inside.

Looking in detail from the conventional water tube (registered patent 10-1023350) as follows.

1 is a diagram three-dimensionally showing the overall configuration of the water tube according to the prior invention. Referring to Figure 1, the prior art, the upper and lower sheets (10, 20) formed through the through hole, the upper and lower seats in the water tube, the inner end of the upper and lower sheets (10, 20) The inner sheet 30 is sandwiched between the ends 10a and 20a, and the first inner band is formed on the inner end portion 10a of the upper sheet 10 and the outer surface of the upper end 30a of the inner sheet 30. 40 is fused by high frequency heat, and the second inner band 42 is brought into contact with the inner end portion 20a of the lower sheet 20 and the outer surface of the lower end 30b of the inner sheet 30 to heat the high frequency heat. Fusion. In addition, the outer end portions 10b and 20b of the upper and

lower sheets

10 and 20 are in contact with each other so that the outer band 50 is brought into contact with the outer end outer surfaces of the upper and

lower sheets

10 and 20 to generate high frequency heat. It is constructed by fusion.

As described above, the conventional invention has a disadvantage in that it is difficult to use for versatile use such as pillows or cushions because it is used only for the original dip.

In addition, there is a problem that the manufacturing cost increases because the handle is attached separately.

In addition, the conventional tube has the disadvantage that the tubes can not be used to connect with each other.

The present invention is to solve this problem of the prior art, the object is to provide a tube that is used as a pillow or cushion.

Another object of the present invention to provide a tube having a handle on the slope of the tube.

Still another object of the present invention is to provide a tube having a predetermined connection member on one side.

In order to achieve the above object, the present invention has a cross-shaped top sheet to form an upper portion of the tube, a cross-shaped lower sheet to form a lower portion of the tube, and so that the center of the tube does not swell during air injection, The inner sheet for holding the center portion of the tube is joined to both the central inner surface of the upper sheet and the central inner surface of the lower sheet, and a handle for providing grip by forming holes in the upper, lower, left and right protrusions of the upper and lower sheets. A part and the junction part which are sealed by the high frequency heat | fever so that a tube is sealed as an edge of the said upper and lower sheet are comprised.

At this time, the top sheet may be provided on one side, the air injection unit for injecting air into the tube.

And any one of the left and right protrusions may be provided with a recess groove in the vertical line of the junction.

In addition, the other of the left and right protrusions may be provided with a concave projection on the vertical line of the junction.

And one of the upper and lower protrusions may be provided with a recess groove in the horizontal line of the junction.

Finally, the other one of the upper and lower protrusions may be provided with a concave protrusion on the horizontal line of the junction.

The present invention can be used not only for playing but also for various purposes such as pillow or cushion.

In addition, the handle is formed to increase the convenience of carrying.

In addition, by implementing the connection between the tubes, there is an advantage to make a tube assembly of various shapes and sizes.
