Description

[Detailed Description of the Invention] The present invention relates to a flexible cleaner hose that is used by having one end plugged into a cleaner body and the other end connected to a cleaning tool.

It is important for this type of flexible cleaner hose to be able to move the cleaning tool freely and nimbly in various directions along the floor surface during cleaning work, and for this purpose, the flexible cleaner hose must be flexible. You need to be good at it and have a certain amount of length.

The hoses that have been commonly used in the past have been a series of long hoses that have a bellows-like peripheral wall over their entire length to provide flexibility, but with this method, the hoses can be stored compactly after cleaning. Even if you try to wind that long hose, 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. It was hot.

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, the length may be unexpectedly shortened due to the stress in the axial direction when the hose is swung around during cleaning work while the hose is stretched, and the suction that acts inside the hose. This is inconvenient and not practical. As yet another means,
Divide a hose with a constant diameter into multiple pieces in the axial direction,
It is also conceivable that these divided hoses can be connected and separated, for example, through a screw structure, but in this case, by separating the divided hoses and arranging them side by side, the length when stored can be reduced, but the hose itself It is inconvenient in use that the volume or bulk occupied by the entire device cannot be reduced, and moreover, complicated connection and separation operations must be performed each time the device is used and stored.

The present invention solves the above-mentioned drawbacks of the conventional devices.The overall volume of the device can be made extremely small when not in use, such as after cleaning, and it is easy to switch between the used state and the unused state. The purpose is to provide a flexible cleaner hose that has excellent cylindrical shape retention, flexibility, and airtightness that are sometimes required.

The flexible cleaner hose according to the present invention, which was taken to achieve the above object, has a connected state in which the entire length is long by sliding expansion and contraction in the axial direction of a plurality of mesh tubes having different diameters, and a plurality of connected states in use. It is configured to be able to switch freely between a shortened storage state by being inserted into one part or almost one part, and an axial end of each of the mesh tubes is provided with A stopper and a stopper receiving portion are formed on the outside of each of the mesh tubes to prevent the extraction of adjacent mesh tubes by engaging or abutting each other, and the mesh tubes are arranged in the long connected state during use. The entire axial length of the net-like cylinder when it is in the position is covered with a non-air permeable and flexible cylindrical membrane, and both end portions of this cylindrical membrane in the axial direction of the cylinder are connected and positioned at both ends. It is characterized by being airtightly fixed to the outer circumferential surface of the outer end of the net-like tube, and the following effects have been achieved.

To describe the effects of the present invention, on the one hand, a sufficient length necessary to allow free movement of the cleaning tool during cleaning work can be obtained by connecting a plurality of mesh tubes. On the other hand, when stored, regardless of whether this hose is a flexible hose, due to the sliding reduction in the axial direction, each of them overlaps inside and outside, and the overall length becomes one-fold or almost several-fold of the above-mentioned connected state. Since the hose is switched to the shortened storage state and the cylindrical membrane contracts in the axial direction, there is an advantage that the overall volume is extremely small even though it is a flexible hose as described above.

However, the main feature of the present invention is as follows.

Since the airtightness of this flexible hose is taken care of by the cylindrical membrane while it is being used as a cleaner, it is sufficient for this mesh tube to have the function of maintaining the shape of the flexible hose when in use. There is no need for a continuous wall to maintain airtightness over the entire length of the cylinder. Therefore, since this mesh tube has a large number of through holes, it has the advantage that the mesh tube itself can easily have good flexibility.

In addition, since airtightness is not required at the connecting portion between these reticulated tubes in use due to the airtightness maintained by the cylindrical membrane, there is no need to consider the airtight condition in the connected state at all for this connecting portion. The connecting part is easy to attach and detach, and the connecting part has the advantage of being easy to manufacture because it only needs to be designed and manufactured taking into account design conditions sufficient to maintain the connected state during the connected use state.

Since the cylinder body for maintaining the shape of the cleaner hose during use is a mesh cylinder, there is an advantage that the flexible cleaner hose can be easily constructed to be lightweight.

Embodiments of the present invention will be described below based on the drawings.

In FIGS. 1 and 2, 1, 2, and 3 are mesh tubes made of soft synthetic resin having a perforated peripheral wall such as a diamond shape or a square shape. The diameter is successively smaller and the length becomes longer as the item 1 increases, and
Due to sliding expansion and contraction in the axial direction, as shown in Figure 1, the hose is connected to the fully extended state and the second
As shown in the figure, the entire hose overlaps each other inside and outside and is switchably connected to the hose storage state, which is about one third of the length of the used connection state in the drawing.

As clearly shown in FIG. 3, the elongated hoses are attached to the connecting ends of the mesh tubes 1 and 2 and 2 and 3 that are adjacent to each other in the axial direction of each of the groups of mesh tubes 1, 2, and 3, respectively. Annular stoppers 4 and 5 and annular stopper receiving portions 6 and 7 are formed, respectively, to elastically fit into each other in the connected state of use and prevent the adjacent mesh tubes 1 and 2 and 2 and 3 from being pulled out. At the same time, at the free end of the reticular tube 3 having the largest diameter,
A straight pipe part 3a for plug connection to the cleaner main body A shown in FIG. A tube portion 1a is formed.

And, on the outside of each of the mesh tubes 1, 2, and 3,
These mesh tubes 1, 2, and 3 have a length slightly shorter than the total length in the axial direction when they are in the above-mentioned state of use and connection, and are made of non-breathable and highly flexible material, for example, fiber cloth. A series of integral cylindrical membrane bodies 8 are enclosed, and only the end portions 8a and 8b of the cylindrical membrane body 8 in the cylinder axis direction are bonded to the outer circumferential surfaces of the mesh tubes 1 and 3 located at both axial ends. This cylindrical membrane body 8 is fixed in an airtight state through means such as thermal welding means or the like.
