Description

[Detailed description of the invention] [Industrial application field] The present invention is a flexible,
Regarding flexible cleaner hoses.

[Conventional technology]

It is important for this type of cleaner hose to be able to move the cleaning tool freely and quickly in various directions along the floor surface during cleaning work, and for this purpose the cleaner hose must be highly flexible. A certain length is required.

The ones that have been used frequently include, for example, Jikkosho.
As shown in Japanese Patent No. 46-15559, it was a long, continuous hose with a bellows-like peripheral wall formed over its entire length to provide flexibility; Even if you try to wind the hose after work, the hose itself is difficult to bend sharply, so the overall volume in the rolled state is still quite large, which has the disadvantage of requiring a large amount of space when stored in a storage case or closet. .

In addition, in order to make the hose as compact as possible when not in use, for example,
It is also conceivable to use a hose that can be changed into two stable lengths in the axial direction as the cleaner hose, as disclosed in the above publication.
In this case, there is an inconvenience that the length of the hose may be unexpectedly reduced due to the hose being swung around during cleaning work while the hose is in an extended state, and the suction acting within the hose. do not have. As another method, it is possible to divide a hose with a constant diameter into a plurality of parts in the axial direction, and configure the divided hoses to be connected and separated by, for example, a threaded structure, and this has been put into practical use in some cases. However, in this case, the length when stored can be reduced by separating the divided hoses and placing them side by side, but the absolute volume or bulk of the hose itself cannot be reduced, and moreover, it is difficult to connect and separate the hoses each time they are used and stored. There is an inconvenience in using this method as it requires additional work.

[The problem that the idea aims to solve]

This invention eliminates the above-mentioned conventional drawbacks, and allows the overall volume to be extremely small when not in use, such as after cleaning, and it is easy to switch between the used state and the non-used state, and moreover, it can be controlled remotely. The purpose is to make it possible to obtain what is possible at a low price.

[Means to solve the problem]

The technical means of the present invention taken to achieve the above object is to provide a cleaner hose composed of a combination of a flexible hose and a conductor for remote control, as described in [A] to [D] below. This means that we have the following.

[B] The flexible hose is composed of a hose body formed by connecting a plurality of divided flexible hose parts with different diameters, and a cylindrical cover that covers the outer periphery of the hose body. There is.

[B] The hose main body can be used in a connected use state in which each divided flexible hose part is extended in the axial direction by relative movement of each divided flexible hose part in the axial direction; The flexible hose parts overlap each other in the axial direction so that the small diameter divided flexible hose part can be freely switched to a contracted storage state in which it is inserted inside the large diameter divided flexible hose part.

[B] The cylindrical cover has both ends fixed to both ends of the hose body, and has the same or almost the same length as the length of the hose body in the connected and used state, Constructed of highly flexible and stretchable material.

[d] The remote control conducting wire is attached to the inner surface of the cylindrical cover along the axial direction thereof.

[Effect]

The effects of taking the above technical measures are as follows.

i In other words, to summarize, a hose with the necessary flexibility and length to allow free movement of cleaning tools during cleaning work is divided into multiple flexible hose parts in the axial direction. In this way, the plurality of divided flexible hose parts are made to have different diameters, and each hose part is concentrically connected by sliding in the axial direction, allowing the use of a large total length. By connecting the parts so that they can be switched between the storage state where the length is shortened by overlapping the inside and outside, the length and good flexibility required for cleaning work can be achieved.
In addition, although it can be used no different from a conventional series of long flexible hoses, when it is not in use, such as after cleaning,
The small-diameter hose portion can be sequentially pushed into the large-diameter hose portion and stored in a low-volume manner.

Moreover, as mentioned above, the flexible hose can be easily and inexpensively made from a material with excellent flexibility and pliability, such as thin fiber cloth, and the cylindrical cover can easily be attached with a remote control lead wire. It is possible to obtain a hose that has the function of remotely controlling the operation switch provided on the cleaning tool body by simply fitting it on the outside. As in the case of attaching
There is no need for sophisticated processing techniques to maintain the conductor state while allowing the hose portion to slide and expand and contract.

In addition, since the conducting wire for remote control is attached along the axial direction on the inner surface of the cylindrical cover, it is easy to attach the conducting wire to the cylindrical cover, and it can be wound spirally. In comparison, it is extremely short.

[Effect of idea]

From the effect of i above, by using the internal space of the large-diameter hose section as a storage space for the small-diameter hose section, the length can be made very short and the external bulk can be made very small, resulting in a significant saving in storage space. ,
Moreover, switching between the storage position and the use position can be easily performed by a very simple operation such as a push-in slide or a pull-out slide.

Further, due to the above-mentioned effects, the overall volume can be made very small when not in use, and the length of the conducting wire can be shortened, so that it is possible to provide a device that can be remotely controlled at a low cost as a whole.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

In Figures 1 and 2, 1, 2, and 3 are
This is a split flexible hose part that is formed by molding into a bellows-shaped peripheral wall 1a, 2a, 3a using synthetic resin materials such as EVA resin (ethylene vinyl acetate copolymer), vinyl chloride resin, and polyethylene. The flexible hose portions 1, 2, and 3 are constructed such that the diameter of the flexible hose portion 1 toward one end in the axial direction is sequentially smaller and the length thereof is sequentially longer. as,
The hose is connected so as to be switchable between a used state in which the entire length is extended and a stored state in which the entire hose is contracted and overlapped inside and outside of each other as shown in FIG. A hose main body 16 is constructed, and the hose main body 16 and a cylindrical cover 12 covering the outside thereof constitute a flexible hose.

As clearly shown in FIG. 3, the above-mentioned elongated hoses are used at the ends for connecting the axially adjacent hose parts 1, 2, and 3 of each of the divided flexible hose parts 1, 2, and 3 groups. straight tubular peripheral wall portions 8, 9, and 10 for maintaining airtightness that closely fit inside and outside in the state;
11 is integrally formed over an appropriate length in the axial direction, and the straight tubular circumferential wall portions 8, 9 and 10, 11 are arranged at approximately central positions in the axial direction so as to be elastically connected to each other when the elongated hose is in use. Annular stoppers 4 and 5 for fittingly engaging and preventing the adjacent hose sections 1 and 2 and 2 and 3 from being pulled out.
and annular stopper receiving portions 6, 7 are formed, respectively.

Among the divided flexible hose parts 1, 2, and 3, the free end of the divided flexible hose part 3, which has the largest diameter, is formed with a straight pipe part 3b for insertion and connection to the cleaner main body A shown in FIG. Furthermore, a straight pipe part 1b for insertion and connection to a hard hose C connected to the cleaning tool B side is formed at the free end of the split flexible hose part 1 having the smallest diameter.

Reference numeral 12 denotes a cylindrical cover that can cover almost the entire length of the divided flexible hose parts 1, 2, and 3 when the hoses are in use;
As clearly shown in the figure, the inner surface of the cylindrical cover 12 is formed into a straight tube shape from a material with excellent flexibility and pliability, such as knitted fabric, woven fabric, or nonwoven fabric. A remote control conducting wire 13 is attached along the axial direction, and in the stored state shown in FIG. 2, the hose 3, which has the largest diameter, is shrunk into a wrinkled shape on the outer periphery.

Both ends 12 in the axial direction of the cylindrical cover 12
