Description

[Detailed description of the invention] [Technical field of the invention] This invention relates to a hose for a vacuum cleaner.

[Conventional technology] Conventionally, hoses used in vacuum cleaners are
Although it is flexible and can be bent freely, there is almost no elasticity in the length direction, so when storing the hose, methods such as hanging it on a nail attached to the wall are used. It was extremely inconvenient to handle.

[Summary of the invention] This invention eliminates the above drawbacks and allows the hose, which is stretched in its natural state, to be easily stored by reducing the internal air pressure and shrinking the hose in its length direction. It provides a hose.

[Embodiment of the invention] Hereinafter, an embodiment of the invention will be described based on the drawings. 1 is a tubular support pipe having a remote switch 2 on its upper part for starting and stopping the vacuum cleaner main body A; 3 is a support pipe 1; A connecting pipe 4 connects an extension pipe rotatably connected to the vacuum cleaner main body A, and a connecting pipe 4 has an insertion port 5 connected to the vacuum cleaner main body A, and a pipe portion 6 that is connected to the insertion port 5 at approximately right angles is formed. entrance body,
7 is a telescopic hose that is adhesively fixed to the end of the support pipe 1 and the pipe portion 6 of the insertion port body 4 and extends in a normal state; 8 is a telescopic hose that surrounds the part where the telescopic hose 7 is adhesively fixed to the support pipe 1; An elastic engagement piece 9 is integrally formed with a protective cover fixed to the support pipe 1 in such a manner.

Reference numeral 10 denotes a protective cover fixed to the insertion port body 4 so as to surround the retractable hose 7 portion adhesively fixed to the pipe portion 6, and a pair of hanging portions 11 on the left and right sides are integrally formed.

Reference numeral 12 indicates a storage cover made of a flexible material, which is adhesively fixed to the inner surface of the protective cover 10 and placed on the outside of the elastic hose 7 so as to cover approximately half of its length; A plurality of engagement holes 14 that are adhesively fixed and a plurality of ribs 15 around the entire circumference.
16 is a fixing ring having a hanging hole 17 that is rotatable around a cover installed on the storage holder 13.

The retractable hose configured as described above can be used as a vacuum cleaner hose by connecting the outlet 5 to the vacuum cleaner main body A in the same way as a conventional hose. Since it is fixed to the insertion port body 4 side, the bending life of the telescopic hose 7 is increased in strength.

On the other hand, during storage, when the vacuum cleaner is operating, the connection pipe 3
If the mouth of the hose is sealed with your hand, the elastic hose 7 will contract due to negative pressure as shown in FIG. Then, hose 7 will not stretch,
It can be kept small and stored as is.

At this time, since there are a plurality of engagement holes 14, the extensible hose 7 is twisted during contraction and storage, and the engagement piece 9 can be inserted casually in any position. In addition, when taking out the hose, by grasping one with both hands and rotating either one, the engagement piece 9 will come out of the engagement hole 14 and the telescopic hose 7 will automatically extend, making the operation very easy.

Next, the telescopic hose 7 is stored, the storage cover is bent under the storage, and the hanging hole 17 is fitted into the hanging part 11, so that the size can be further reduced by bending it as shown in Fig. 4, which saves space. Connect.

In addition, when folded, it can be placed on the main body A as shown in FIG. 5 for ease of use, which also leads to a display effect as a product.

Furthermore, since the fixing ring 16 rotates around the cover when folded, even if the storage cover 7 is assembled in a twisted manner, it can be attached freely. Also hanging part 1
1 is formed as a pair on the left and right, so it can be folded and set on either the left or right side.
It is very easy to use regardless of whether you are right-handed or left-handed.

[Effects of the invention] As described above, according to this invention, the telescopic hose can be contracted and stored within the storage cover, and the storage cover can be further bent and held under the storage of the telescopic hose. This has the practical effect of requiring less space during storage and making it easier to use, as even if the storage cover is twisted, it can be handled without causing any problem in the engagement.

[Brief explanation of the drawing]

Fig. 1 is a sectional view of the main part of a hose showing an embodiment of this invention, Fig. 2 is a sectional view of the main part when stored, Fig. 3 is a cross-sectional view of Fig. 1, and Figs. FIG. 5 is a perspective view similarly showing the state during storage. In the figure, 1 is a support pipe, 4 is an insertion port, 7 is a telescopic hose, 9 is an engagement piece, 11 is a hanging part, 12 is a storage cover, 14 is an engagement hole, and 17 is a hanging hole. .
