Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a hose for a vacuum cleaner, whether vertical or movable on the floor, which communicates the main body of the vacuum cleaner with a nozzle, etc.

BACKGROUND OF THE INVENTION In recent years, hoses used in vertical or movable vacuum cleaners are difficult to handle during cleaning, so there has been an increasing demand for vacuum cleaner hoses that are easy to handle and have a high storage capacity.

In a conventional vertical vacuum cleaner, as shown in FIG. 8, the hose 44 that communicates the dust collection chamber 42 of the vacuum cleaner main body 41 with the floor nozzle/L/43 is a connecting pipe with a nozzle part 434111 that can be attached or detached. A telescopic device similar to 45 was used.

In addition, as another example, as shown in FIG.
In the case of using the hand hand/L/64 provided on the end face of the hose, there is one in which a power supply wire (not shown) is arranged in the hose 53. As shown, the storage hose 65 is arranged to cover the expandable hose 63, and the storage hose 56 is contracted in the direction of the arrow using the negative pressure when the suction port 56 of the hose 7.63 is sealed. It was common to store it inside and fix it with a screwdriver 67 or the like.

Problems to be Solved by the Invention In the vertical vacuum cleaner shown in FIG. 8, there is no problem in normal cleaning because the hose 44 is always fixed to the floor nozzle 1V43, but when the hose 44 is connected to the floor nozzle 1V43, there is no problem. When using V46, etc., the hose 44 was difficult to use because it contracted in the direction of arrow B due to the close contact of the mouthpiece to the surface to be cleaned, despite the hose 44 being flexible. . Also.

As shown in FIG. 9, even in an electric cleaning machine equipped with a storage hose 7-55 in which the retractable hose 53 can be stored, the hose 63 becomes shorter when it contracts, making it easier to store it. Even when the hose 63 is attached to the floor etc., it contracts in the direction of arrow C, causing the hand at hand) v54
It was difficult to clean because it was pulled by the vacuum cleaner itself.

Furthermore, the storage hose 7-56, which needs to store the hose 63 inside, has a larger external shape, and the hose 63 has to be stored inside.
The softness of the hose 53 and storage hose 65 are hindered, making it unusable, and the area where the hose 53 and storage hose 65 overlap, as shown in Figure 1o, is a double wall, which increases the overall weight of the hose. Ta.

The present invention solves the above-mentioned problems by preventing the hose itself from shrinking during suction, which is the case with a telescopic hose, and by creating a vacuum cleaner that is easy to store after cleaning without increasing the outer diameter of the hose as in the past. The purpose is to provide hoses.

Means for Solving the Problems In order to achieve the above object, the present invention has a first means that includes a retractable hose having connection pipes at both ends, and one end connected to one of the connection pipes on the outer periphery of the hose. , a plurality of first steel wires provided in the longitudinal direction of the hose, and this first w4
a first ring slidably held on the wire; a second ring supporting the other end of the first steel wire; one end connected to the Ikegata connection pipe and offset from the first steel wire; a second steel wire that slidably passes through the second ring and has its other end connected to the first ring, and the first ring and the second ring abut the telescopic hose. The structure is such that it can be stretched and held until the end.

In the second aspect of the present invention, at least one of the plurality of first steel wires and second steel wires is an electric wire for power supply, and an electric wire is provided at the abutting portion of the first ring and the second ring. The structure is provided with contacts that can be connected to each other.

Function: As described above, the vacuum cleaner hose of the present invention has steel wires attached to each connecting pipe provided at both ends of the freely retractable hose, and these wires are held by a ring slidably provided around the outer circumference of the hose. By doing so, even when the hose is stretched, the rings integrated with the connecting pipe are held and fixed together through the steel wire made of an elastic body, so even if the hose tries to contract due to adsorption force, the elasticity of the steel wire is maintained. Since the hose can be prevented from shrinking due to the nature of the hose, it does not make cleaning difficult for the user due to hose shrinkage, etc., and by using the steel wire for the power supply wire and providing contacts on the ring to connect each wire, The retractable hose can be stretched and used with or without a hand control, and since there is no need for a hose to be stored to cover the hose when the hose is contracted, this can be done without significantly increasing the external dimensions of the hose. .

Furthermore, by shrinking the hose, even when the hose is attached to the main body of the vacuum cleaner and placed in a closet, it is easy to clean as there is no slack due to the length of the hose. be.

EXAMPLE Hereinafter, a first example of the present invention will be described with reference to FIGS. 1 to 3. As shown in the figure, a floor nozzle I is located below the main body 1 of a vertical vacuum cleaner that has a dust collection chamber (not shown) inside.
V2 is rotatably attached, and the dust collection chamber and the floor nozzle/V2 communicate with each other through a connecting pipe 4 and a rotary pipe 5 provided at both ends of a telescopic hose 3.

Then, a first steel wire 6 held in the longitudinal direction of the hose 3 is provided on the outer periphery of the connecting pipe 4, and this steel wire 6 is attached to the hose 3.
It is held and fixed to a second ring 9 that passes through a first through hole 8 of a first ring 7 that is slidably provided on the outer periphery.

On the other hand, in the rotary pipe 5 flit, the second steel wire 10 is attached to the outer periphery of the hose 3 in the longitudinal direction of the hose 3 at a different position, shifted approximately 9o0 from the above-mentioned first steel wire 6. After passing through the second through hole 11 provided in the second ring 9, it is held and fixed to the first ring 7.

In the above configuration, when the hose 3 is connected between the main body 1 and the floor nozzle/1/2 as shown in FIG. From this state, the first ring 7 can be contracted by pulling it in the direction of the arrow mark, and the second ring 9 can be pulled in the direction of the arrow E. Furthermore, when using the hose 3 by stretching it as shown in FIG.
3 is extended from the state shown in FIG. 1(B), and the fitting 12 provided on the second ring 9 shown in FIG. By holding it together, the first ring is closed and the second ring 9 is prevented from separating.

As a result, as shown in Fig. 3, a gap nozzle (v 13 'fi) is attached to the tip of the connecting pipe 4, and suction force is applied to the tip, causing the hose 3 to stretch even when a shrinking force is applied to the hose 3.
The elastic force of the first steel wire 6 and the second steel wire 1Q can be used to repel the shrinkage of the steel wire 1Q.

Next, a floor movable vacuum cleaner according to a second embodiment will be described with reference to FIGS. 5 to 7. As shown in the figure, in the case where a switch 23 for starting and stopping the motor 22 placed inside the main body 21 is provided on a hand handle 25 provided on the end surface of the hose 24, the main body 21 and the switch 23 are provided.
It is necessary to connect the two parts through the hose 24, but in the figure, there is a rotary pipe 26 provided on the main body 21g1II of the hose 24.
Connect the electric wire placed on the second steel wire 27 provided in the longitudinal direction of the hose 24,
While connecting the wires arranged in a twisted manner to the first steel wire 28,
By arranging the contacts 31 and 32 connecting the first steel wire 28 and the second steel wire 27 to which the electric wires are connected, respectively, to the second ring 29 and the first ring 3o, the contacts 33 provided in the second ring 29 are arranged. The electric wire between the rotary pipe 26 and the hand handle 25 can be connected by coupling it with the first ring 3o at.

When the hose 24 is stored together with the main body 21 in a contracted state, the hose 24 is
Since the hose 24 is approximately % of the length of normal use, the hose 24 can be easily stored without any slack, and the main body 21 can be compactly stored at a height that can be stored in a closet or the like.

Effects of the Invention As is clear from the above embodiments, a vacuum cleaner hose has the following effects by regulating the shrinkage of a stretchable hose with a plurality of steel wires arranged around the outer circumference of the hose. It is something that can be provided.

By using the hose of this embodiment for the hose that communicates with the dust collection chamber and the floor nozzle (Vf) in a vertical vacuum cleaner, etc., it can be shortened during normal use, and when the hose connection pipe is removed from the floor nozzle, it can be shortened to approximately Even if the suction force is strong, the hose will not shrink due to the elastic force of the steel wire placed around the outside of the hose.

In addition, in vacuum cleaners that have a switch for controlling the main unit on the hand handle provided on the end of the hose, the necessary number of the aforementioned multiple steel wires are used as electric wires for power supply, and when the hose is stretched out, the outer circumference of the hose is There are contacts for connecting each power supply steel wire to the ring placed in the ring, so even if the hose has electric wires, the hose can be shortened when stored and lengthened when used. It is something that can be done.
