Description

[Detailed description of the invention] <Industrial field of application> The present invention is a hose for transferring and guiding fluids such as gases, liquids, powders, etc., especially a flexible hose with a spiral reinforcement. This invention relates to a hose that is shaped like a cone.

<Prior Art> Hoses with conical helical reinforcement of this type have existed for some time. However, conventional hoses of this type have only been so-called single-piece hoses in which the tube wall is formed in one piece.

<Problems to be solved by the invention> Such a conventional hose with a conical spiral reinforcement has elasticity and flexibility by itself, but it maintains a contracted posture. In order to transport the product, a wrapping body is required to maintain the position, and in order to reduce the volume after use and store it in the storage position, a packaging body is required to maintain the position. It requires the necessary parts and containers. Moreover, it is quite troublesome to accommodate the hose in the contracted position in such a storage member. In addition, there is a disadvantage that the housing member or container gets in the way while the hose is used in the stretched position.
Furthermore, if the hose is used for a long period of time, there is a risk of parts being lost.

The purpose of this invention is to eliminate these conventional drawbacks and troubles, and it is extremely easy to put the hose in a reduced position, and it is also extremely easy to maintain that position, making it easy to store. Here, we propose a flexible hose that can be easily made into a state that does not take up much space or transportation.

<Means for Solving the Problems> The present invention will be explained with reference to FIGS. 1 to 3, which show the configuration of the present invention as an example. a conical flexible hose Q, and a conical bag body 5 having a fastener 6 attached to its body along the longitudinal direction.
The conical flexible hose Q is housed in a double tubular shape along the longitudinal direction of the bag 5, and the bag 5 and the hose Q are connected at one end so that they do not move relative to each other. The slider 7 of the fastener 6 attached to the bag body 5 at the other end side and the other end of the hose Q are engaged and connected, and the slider 7
This is a double cone-shaped flexible hose that has a structure in which the engaging side end of the hose Q moves as the hose Q moves, allowing the hose Q to expand and contract.

<Function> Since the present invention has such a configuration, in order to put the internal hose Q in the contracted position, the slider 7 of the fastener 6 is moved in the contracting direction, and the part of the bag body 5 where the hose Q is not attached is rolled up. All you have to do is wrap it around the entire length of the hose Q in the contracted position. Further, when in use, the slider 7 of the fastener 6 can be moved in the direction of extension of the hose.

<Examples> Examples of the present invention will be described below based on the drawings.

(First Embodiment) FIGS. 1 to 3 are diagrams showing a first embodiment of the present invention.

Figure 1 shows the stretched position of the double conical flexible hose in use, and is made of flexible rubber, synthetic resin, or composites of these with various fibers, twisted yarns, woven fabrics, etc. A flexible hose Q having a structure in which a metal conical spiral coil 1 is connected to a flexible wall body 3 via a coating 2 has a diameter that gradually decreases from a large-diameter hose port O to a small-diameter hose port N. It is a small conical flexible hose. This conical flexible hose Q has a conical cylindrical bag body 5 with a fastener 6 attached to its body along the axial direction on the outside thereof.
, and the large-diameter end A of the flexible conical hose Q
and the large-diameter end C of the conical bag are connected by a connecting part E, and the small-diameter end B of the other end of the hose is connected to the slider part 7 of the fastener 6 and the engagement part on the small-diameter side. G
When the fastener 6 is completely closed by the slider 7 as shown in the figure, the small diameter end B of the hose attached to the engagement part G is pulled away from the large diameter end A. The flexible hose Q inside is stretched and fits into the small diameter end D of the bag body 5 and the small diameter end F of both, forming a double conical flexible hose P. form the state of use.

Next, move the slider 7 from the state shown in Figure 1 to the left to bring the fastener 6 into the state shown in Figure 2.
In other words, the slider 7 and the small-diameter end B of the hose are connected and engaged at the engaging part G, and the large-diameter end A of the hose is engaged with the bag C at the large-diameter end E. Since the hoses are connected together, the hoses are gradually brought into a contracted position. The small diameter end D of the bag body and the slider 7 moved to the left
There is no hose between the bag body 5 and the bag body 5 alone. Therefore, as shown in FIG. 3, the bag body 5 can be folded into a small size, and the internal flexible hose can also be kept in a reduced state, making the overall volume of the hose small and compact. Therefore, it is convenient to store and transport.

(Second Embodiment) FIGS. 4 to 6 are diagrams showing a second embodiment, which is another embodiment.

The double hose P shown in Fig. 4 is an example in which the shape of the reinforcing body 1 of the internal conical flexible hose Q is a horizontally long rectangular shape, and the fastener 6 is closed and the double hose P is in an extended position. FIG. 5 shows the state in which the fastener 6 of this double hose is moved to the left and the internal hose Q is contracted, and FIG. 6 shows the state in which the hose P is stored.

(Third Embodiment) FIGS. 7 and 8 show a third embodiment which is still another embodiment.
It is a figure showing an example.

In the double hose P shown in Fig. 7, the reinforcing body 1 of the internal conical flexible hose Q has a horizontally long rectangular shape, and is made of hard synthetic resin and has two conductive and reinforcing metal wires 8 inside it. , 8' is used as a reinforcing material to form a conical spiral coil, and the guide wires 8, 8' are used as remote control energizing wires to form a so-called remote control hose. The ends of the conductive wires 8 and 8' embedded in the reinforcing body 1 are connected to the outside through terminals 9 and 10 at the larger diameter end A, and to the outside through terminals 11 and 12 at the smaller diameter end B, respectively. The structure is such that it can be used as a current-carrying wire. In addition, the flexible hose Q in this embodiment has rings H, I, on the inner side of the inner hose Q and the bag body 5, respectively, at the ends of both the large diameter side and the small diameter side.
J and K are fixed to each other, and spaces M and L are formed between the internal hose Q and the bag body 5 in their respective overlapping positions (extended positions of the hoses). That is, at the large-diameter end of the hose P, the inner ring I of the double rings I and E is fixed to the end A of the flexible hose, and the outer ring K and the end C of the bag body 5 form a connecting part. These rings I and K are connected by E.
The hollow part M formed between the inner and outer hoses becomes an external passage connection port, and the hollow part M formed between the inner and outer rings J and H at the small diameter side end is formed through the gap part N between the internal flexible hose Q and the bag body 5. It is designed to exit into the hollow part L.

FIG. 8 is a diagram showing the stored state of the hose.

The internal conical flexible hose Q may have any structure as long as it is a stretchable flexible hose such as those listed above, and it may be a hose that is stretched in its natural state when stored. It may be a hose that can be contracted, or conversely, it may be a hose that is contracted in its natural state and then stretched when used. This hose may be a hose on which internal pressure is applied, or may be a vacuum hose that suctions the inside of the hose.

The connection between the inner flexible hose Q and the outer conical bag 5 on the larger diameter side may be removable or fixed, and may be bonded using an adhesive or melted. Furthermore, the connection between the hose and the slider may be removable or fixed.

The fastener is selected from airtight or breathable fasteners depending on its purpose.

<Effects of the invention> The double cone-shaped flexible hose referred to in the invention is a flexible hose having the structure and function as explained in the above embodiments, and therefore has the following effects. .

In other words, because the hose has a double structure, the outer bag protects the inner hose when the hose is in use, extending the life of the inner hose.Even if the inner hose is damaged, the outer bag protects it. When an airtight fastener is used on the body, the bag maintains its airtightness as a double tube and can be used continuously.

Furthermore, when the hose is used for delivery, the outer bag acts as a restrictor to prevent the inner hose from expanding in diameter, thereby preventing the inner hose Q from expanding more than necessary and bursting.

In addition, the slider of the fastener attached to the bag according to the present invention is locked to the small-diameter end of the internal hose, so when the slider is in the contracted position when not in use, the internal hose is moved by moving the slider. The bag can be placed in a contracted position, and the bag can simply be rolled up or folded, making it extremely easy to change the bag to a contracted position. Since the internal hose can be placed in the stretched position simply by moving it, the effect is that the change to the stretched position can be made extremely easily.
