JPH04361725A - Suction hose for expansive/contractive vacuum cleaner - Google Patents

Abstract

PURPOSE:To fix a suction hose in any desired position with possibility of elongating and shrinking by dividing the suction hose into several hose fragments which are connected in slidable system, installing a moving gear through a motor on the stationary hose side of the suction hose, and interposing a spacer between hose segments. CONSTITUTION:A nozzle-fitted hose 6, intermediate hose 7, stationary hose 8 are connected in slidable system, and a spacer 10 and a spring 10-a for it are interposed between these hose members, which are locked together by a band-equipped stopper 11 or put in gliding state. Therefore, the hose members are free from risk of separating. A brake-fitted motor 2 is installed on the stationary hose 8 side, engaged by a moving gear 3 through a motored gear 2-a, and is put in contact with the hose right under the moving gear through the action of a spring 3-a for moving gear, so that the hose is free from risk of slipping off from a rail 4 for moving gear.

Description

[Detailed description of the invention]

[Industrial Application Field] The present invention makes it easy to carry a vacuum cleaner with a suction hose from room to room or store it in a narrow space, and also allows you to freely choose the length of the suction hose even while the vacuum cleaner is in use. This relates to a very convenient vacuum cleaner suction hose that can be expanded and contracted freely.

[Prior Art] Conventionally, when a long suction hose becomes a hindrance when being carried from room to room or stored in a narrow space, it is generally known to remove the joint between the hoses by hand. ing.

[Problems to be Solved by the Invention] The problem to be solved by the present invention is that with a removable suction hose, it is extremely difficult to manually remove the suction hose each time it is used in a narrow space or when stored. It is inconvenient and uncomfortable,
The point is that it is troublesome.

[Means for Solving the Problems] The freely expandable suction hose for a vacuum cleaner according to the present invention is composed of a hose with a nozzle, an intermediate hose, and a fixed hose. Comes with a stopper with a band,
By incorporating a spacer spring and a spacer to actuate the spacer, the hoses can be locked or slid into a sliding state. In addition, a motor with a brake is installed on the fixed hose side, and the spring for the moving gear is applied to the hose directly under the moving gear via the gear with the motor, and by rotating or reversing the motor, each hose can expand and contract freely. In addition, it is constructed so that it can be fixed in any position, and a hose storage stop pin is installed near the top of the motor to prevent each hose from sliding when stored in the fixed hose.

[Operation] In the freely expandable vacuum cleaner suction hose according to the present invention, the nozzle-equipped hose, intermediate hose, and fixed hose are connected in a sliding manner, and spacer springs and spacers are incorporated between each hose. Re,
The stopper with a band allows the hoses to be locked or slid, so each hose will not come apart. In addition, a motor with a brake is installed on the fixed hose side, which meshes with the moving gear via the gear with the motor, and is constantly applied to the hose directly below the moving gear by the moving gear spring, so that the moving gear of each hose is It will not fall off the rail. In addition, a stop pin for hose storage is installed near the top of the motor, so when each hose is stored in a fixed hose, it will not slide down, and even when expanding or contracting, the stop pin for hose storage and each hose will smoothly separate from each other due to the spring for the stop pin. can be done and there is no problem.

[Embodiment] FIGS. 1 to 10 show an embodiment of the present invention, and FIG. 1 shows an overall view of each hose in a contracted state.
Figure 2 shows each hose in its extended state. Embodiments of the present invention will be described below based on the drawings. First, the suction hose is divided into a hose with a nozzle 6, an intermediate hose 7, and a fixed hose 8, and as shown in FIG.
There is a moving gear rail 4 and a hose half circumference 2 in the length direction on the outside.
A hole 5-b for a stop pin for storing the hose is provided at the location.
Spacer spring 10-a in the length direction of the inside left and right
, a spacer 10, and a guide 9 through which the banded stopper 11 can pass, and a stopper guide 11-a is provided so that the banded stopper 11 fits on the outer semicircumference. Further, small holes are made in the intermediate hose 7 and the fixed hose 8 so that the moving gear 3 can be inserted therein, and spacer stoppers 10-b are provided near the upper part of the fixed hose 8 and on the left and right inside of the end portion. Also, the outside of the lower part of the fixed hose 8 is the motor 2 with a brake.
A gear with a motor 2-a is provided through the gear 2-a.
mesh with the moving gear 3, wrap a copper wire around each gear shaft, fix one end, fix the other end to the moving gear 3, create a spring 3-a for the moving gear, and constantly connect the gear directly under the moving gear 3. In addition, by providing a guide 8-a for a detour and a stopper in the length direction inside the fixed hose 8, the final intermediate hose 8
does not rotate and does not come off from the moving gear 3. In addition, a hose storage stop pin 5 is installed near the top of the motor 2 with a brake via a stop pin spring 5-a, and when each hose is stored, the hose storage stop pin 5 is inserted into the stop pin hole of each hose. Make sure it fits in 5-b. The nozzle-equipped hose 6 and the intermediate hose 7 configured as described above, including the band-equipped stopper 11, the spacer spring 10-a, and the spacer 10, are assembled into a set in a fixed hose 8 in a sliding manner. As described above, when each hose is to be extended from its contracted state, by rotating the brake motor 2, the nozzle-equipped hose 6 meshed with the moving gear 3 will be extended while removing the hose storage stop pin 5. While the banded stopper 11 slides on the guide 9, it hits the lower protrusion of the spacer 10, rises to the top, and fits into the banded stopper guide 11-a, locking the nozzle-equipped hose 6 and the intermediate hose 7. It gets stuck and does not move, allowing the hose to extend in an orderly manner. In addition, when each hose is contracted from the extended state, by reversing the brake motor 2 in the opposite manner to the above, the spacer 10 in the intermediate hose 7 is moved to the spacer stopper 1 at the end of the fixed hose 8.
The stopper pin 5 for hose storage installed on the fixed hose 8 just before the hose is stored, which is pressed by the button 0-b, removes the banded stopper 11 from the stopper guide 11-a, releases the locked state, and slides on the guide 9. It gets stuck in the stop pin hole 5-b of the intermediate hose 7 and stops moving.
The structure is such that each hose is stored in an orderly manner.

Effects of the Invention As described above, according to the present invention, the suction hose for a vacuum cleaner, which had conventionally been removed by hand, can be used freely in any position by an extremely simple operation, and the length of the hose can be extended. This eliminates the hassle of having to use the nozzle, and the nozzle can be taken to the same location, whether near or far, which is extremely useful in practical terms. Moreover, it can be widely used not only for suction hoses for vacuum cleaners but also for fishing rods and the like.
