Description

[Detailed description of the invention] The invention is based on a flexible hose tube 1 whose bottom is made of a cylindrical coil spring and a flexible synthetic resin wall.

The flexible hose has a structure in which a cylindrical body with a fastener is provided, one end of the flexible hose is attached to the Feusner slider, and the other end of the hose is attached to one end of the cylindrical body. It is used as a double-structured hose consisting of a closed cylindrical body and a flexible hose, with the zipper open when not in use, and the hose is shrunk and stored at one end of the cylindrical body, creating a cylindrical shape without the hose. This invention relates to a flexible hose that has a structure and function that allows the body to be folded to make the entire hose smaller for storage or transportation.

In conventional flexible hoses of this type, when the hose is in use, the flexible hose is pulled out from the storage container and used as a single flexible hose, and when the hose is not in use, the hose is stored in the storage container. It was something.

Therefore, with conventional flexible hoses of this type, the storage container does not perform any function when the hose is used and the hose is used alone, resulting in a short hose life. The hose has disadvantages in that it is difficult to use because it bends and contracts, and the force exerted by the hose requires extra effort for the user.

The present invention eliminates these drawbacks and has a double structure when using the hose, so the life of the hose is extended and when the internally flexible hose is used for delivery, the hose has a double structure. The cylindrical state prevents the hose from elongating and prevents the internal hose from shrinking even when using a vacuum, providing an easy-to-use flexible hose that does not require extra effort on the part of the hose user. Due to its heavy structure, it can be used to transport dissimilar substances inside and outside, to be used as a reciprocating route, and to be used for transporting and discharging materials.It can also be used to maintain the shape of the hose by sending compressed air to the outside of the internal hose and sealing it. It is a flexible hose with many uses, and when the hose is not in use, it can be compressed into a small size, and the cylindrical body can be folded down to reduce the size of the entire hose for storage or transportation. This is what could have been done.

The present invention will be explained below based on embodiment figures.

Figure 1 shows the flexible hose in use. The internal flexible hose A is made up of a flexible synthetic resin wall 1 and a cylindrical coil spring 2. Inside the body 3, a zipper 4 is attached to the axial body of the cylindrical body 3, which can be opened and closed by a slider 5.

An end E of the internal flexible hose A is attached to the sliders 5 and D, and the other end C of the hose is joined to one end B of the cylindrical body 3.

Therefore, when the zipper is closed, the cylindrical body 3 and the internal hose A constitute a double-walled flexible hose, which is used as a flexible hose in this state.

Next, when the zipper is opened and the slider 5 is moved to the left from the state shown in FIG. 1, it becomes the state shown in FIG.

One end C of the internal flexible hose A is joined to the end B of the cylindrical body, so by moving the slider 5 to the left, the flexible hose A will be moved so that the end E and the slider 5 are at D. Since they are connected, the hose gradually shrinks and is compressed into a tight fit and stored between B and D in a cylindrical shape.

Then, there is no hose between the cylindrical state F end and the slider 5, leaving only the cylindrical body.

Therefore, as shown in Figure 3, the cylindrical body can be folded into a small size, and the internal hose can be reduced to reduce the volume of the flexible hose as a whole, allowing it to be stored or transported. It is.

Note that the internal flexible hose may be of any structure as long as it is a stretchable flexible hose, and the internal flexible hose may be a hose that is stretched in its natural state and that is compressed when stored. Conversely, it may be a hose that is naturally contracted and then stretched during use.

Further, the hose may be used in a situation where internal pressure is applied to the inside of the hose, and the hose may be used in a vacuum state where suction is applied.

The connection between the internal flexible hose and the cylindrical body may be removable or fixed, and the connection between the hose and slider may be either removable or fixed.

Depending on the purpose, airtight or breathable fasteners are selected for use.

Figure 4 shows an example in which the present flexible hose is used as a double hose, with internal flexible hose A and internal flexible hose H.
The attachment parts for the regular cylindrical body 3 have a structure shown by a double ring G, one end B of the cylindrical body is attached to the horizontal ring, and one end C of the hose is attached to the inner ring.

Attach a double ring J to the other end, attach the end F of the cylindrical body to the fitting H, attach one end E of the internal flexible hose with the slider 5 of the fastener 4 and the D part, and then attach the ring to this part. If H is attached and the hook part 7 of H is fitted with the catch part 6 provided on the inner ring of F ring, the fastener 4 will be in the closed state as shown in the figure when the hose is in use. For example, air can be sent from the upper intake port of the ring G to the upper opening M of the ring J through the gap Q between the flexible hose A and the cylindrical body 3.

This is also an example of a situation in which it can be used as a double flexible hose that allows air to pass through the internal flexible hose from the internal ring N of the double ring J to the internal ring O of the G ring.

When the hose is not in use, pull the slider 5 of the zipper 4 to the left, and the latches 6 and 7 will come off and secure the ends E and D of the hose A.
Since they are connected, part E moves to the left, the internal hose is compressed and reduced, and the space between B and D is reduced until they are in close contact.

On the other hand, there is no internal flexible hose between F and D of the cylindrical body 3, leaving only the cylindrical body, which can be folded.

In this way, you can store it in a smaller space when not in use,
It is also transported.

Internal flexible hose A and its 99 rule cylindrical body 3 and gap Q
It is also used to pass different types of things through, as a reciprocating route, as a conveyance/exhaust route, and for heat exchange.

It can be used for many other double pipe applications.

In the example shown in FIG. 5, a vent R is provided in a part K at one end, and an end C of an internal flexible hose A and an end B of a cylindrical body are provided at the other end.
When attached to the ring S and a blower or compressed air is introduced through the vent R, the gap Q between the hose A and the cylindrical body 3 is filled with air, creating a flexible hose that prevents the hose from becoming flat. This is an example.

In this case as well, the other end E of the internal flexible hose is connected to the slider 5 of the fastener 4 at D, roughly connected to the ring H, and the hook 7 and the component and the hook 6 of K are airtightly connected. make it look like this.

Regarding the cotton wire of the flexible hose P when the hose is not in use, see Section 4.
This is done in the same way as in the illustrated example.

In both the usage examples shown in FIGS. 4 and 5, airtight fasteners are used.

Since the flexible hose of the present invention has the structure and function as described above, it has the following various effects.

First, since the hose is used with a double structure, the cylindrical body shares the stress when the hose is bent, stretched, and bent, reducing stress on the internal flexible hose and extending its service life as a flexible hose. Become.

In addition, when the hose is used for delivery, the 99-rule cylindrical body prevents the hose from elongating due to internal pressure, and when using a vacuum, the 99-rule cylindrical body prevents the internal hose from contracting. It is possible to provide an easy-to-use flexible hose that does not require extra effort from the hose user due to elongation of the hose due to internal pressure or shrinkage of the hose due to vacuum.

Next, when using a hose, it has a double structure, so by using the internal hose and the gap between its 99-rule cylindrical body separately, it is possible to send two types of items with one hose, and to It is also a hose that can be used for multiple purposes as a double flexible hose, such as being used as a conveyance/discharge path, or as a heat exchange hose between inner and outer pipes.

This hose can also be used as a flexible hose that helps retain its shape by sealing the internal flexible hose and sending compressed air, etc. to it.

Moreover, the hose can be reduced in size and stored, making it convenient for storing and transporting the hose, reducing storage and transport costs, etc.
This provides a flexible hose with many benefits.
