In addition, a horizontal pipe is provided in the main body of the suction device so that it can rotate freely in the front and rear directions.
A suction tool for a vacuum cleaner is known in which a connecting pipe is rotatably provided in the circumferential direction of the horizontal pipe.

[Problem that the invention seeks to solve]

In the above-mentioned conventional structure in which the connecting pipe is fixed to the suction tool main body and installed, when the extension pipe 4r connected to the connecting pipe is grasped and the floor surface etc. is divided by η, the suction tool main body is attached to the floor If you try to run the suction tool in a curved manner, the part of the suction device that is located on the outer periphery of the curved travel path will rise above the floor surface, making it difficult to clean efficiently. .

In addition, in a structure in which the connecting pipe is fixed in this way, the top + t
To keep the suction port facing the ceiling surface when cleaning, etc., it is necessary to move the extension pipe, etc. in a large parallel manner, and it is difficult to keep the suction port facing the ceiling surface. There was a problem where the J-scarlet was becoming more tiring.

On the other hand, a horizontal pipe is provided in the main body of the suction device so that it can rotate freely in the front and rear directions.
A connecting pipe is installed on this horizontal pipe so that it can rotate freely in the circumferential direction.
,: In the structure, what is the extension tube etc. to be grasped and the suction [ ]! Since there is a large degree of arbitrariness in the positional relationship, the problems described above when the connecting pipe is fixed are eliminated.

However, in this structure, the connecting pipe can rotate υJ without limit.
If it is freely movable, especially when cleaning high places such as ceilings, the weight of the suction tool itself will cause 2 = I to the horizontal pipe.
l.The suction tool itself rotates, and the horizontal pipe rotates too freely relative to the connecting pipe connected to the gripped four-way pipe, so it is difficult to place the suction port to face the top JF surface, etc. It takes a lot of time and h'? +There is a problem that the removal efficiency decreases.

The present invention seeks to solve such problems by providing a horizontal pipe in the main body of the suction device so as to be freely rotatable in the forward and backward directions, and a connecting pipe in the horizontal pipe so as to be freely rotatable in the circumferential direction. [In a vacuum cleaner suction tool that allows arbitrary positional relationship between the suction port of the suction tool body and the extension pipe connected to the connecting pipe, the connecting pipe can be rotated more than necessary. Therefore, the purpose is to make it possible to clean high places such as ceilings 1 ton more efficiently (without having to take time and effort to make the suction port face the ceiling surface when lifting). It is something to do.

[Means for solving problems]

The vacuum cleaner suction tool of the present invention has a connecting pipe on the right side of the mating part, and a fitting part in which the mating part of the connecting pipe is rotatably fitted, and the connecting pipe is circularly fitted. The suction tool body includes a horizontal pipe that is rotatably held in the circumferential direction, and a suction device main body that holds the horizontal pipe rotatably in the front-rear direction and has a suction port that communicates with the connecting pipe via the horizontal pipe, and A regulating part for regulating the rotation of the connecting pipe is provided at the fitting part of the pipe or the fitting part of the horizontal pipe.

Then, the fitting part 33 of the horizontal pipe 31 is fitted into the fitted part 42 through its front opening, and the engaging protrusion 36 of the fitting part 33 is inserted into the fitted part 42. By engaging with the matching groove 44, the connecting tube 41 is held rotatably in the circumferential direction by the horizontal tube 31, with its front end abutting the annular protrusion 35 of the horizontal tube 31. Further, the rotation range of the connecting pipe 410 is restricted to within approximately 180° by the engaging protrusion 3G of the horizontal pipe 31 coming into contact with the restricting portion 45 of the engaging member 44. ing.

Next, the operation of this embodiment will be explained.

This suction pipe is used, for example, by connecting an extension pipe or the like to the constriction pipe 41 (a), and connecting a hose or the like connected to a vacuum cleaner to this extension pipe.

When cleaning a floor surface or the like, the suction port body 2 is used while being mounted on the holding body 3.

For example, in order to attach the suction port body 2 that has been detached from the holder 3, first, the front locked portion 25 of the holder 3 is engaged with the fixing catch 1F portion 17 of the suction port body 2, and then, The holder 3 is rotated downward about its front edge.

So 1 - Inclined surface 2 of the rear locked part 24 of the holder 3
4a is pressed against the inclined surface 11a of the locking claw part 11 of the suction port body 2, and the movable locking part 12 has the locking claw part 11 formed therein.
When it tilts backward due to its elasticity, the rear locked portion 24 climbs over the locking claw portion 11, and the locking claw portion 11 is engaged with the rear locked portion 24 from above. Then, the suction port body 2 is mounted on the holding body 3. In this state (brush bristles 2 of holder 3)
6 is stored in the storage chamber 14 of the suction port body 2.

Then, when the vacuum cleaner is driven and the lower surface of the suction port body 2 is slid along the floor surface, the dust led from the suction groove 7 is sucked in from the suction port 6, and the horizontal pipe 31 and the connection tube 41
is led to the dust collection chamber of the vacuum cleaner.

On the other hand, when cleaning walls, ceilings, etc., the suction port body 2 is dirty due to floor cleaning, and it is more convenient to use only the small holder 3, so the suction port body 2 is removed and used. do. To remove the suction port body 2 from the holder 3, first operate the movable locking part 12 and tilt it backwards to engage the locking claw part 11 with the rear locked part 24 of the holder 3. Then, the front side locked part 25 of the suction device main body 21 is released from the fixed locking part 17 of the suction port body 2.

Then, the suction port 22 of the holding body 3 is opposed to a wall or ceiling surface, and dust is sucked through the suction port 22 for cleaning. At this time, dust can be scraped out by the brush bristles 26 protruding around the suction port 22, so that cleaning can be performed efficiently.

In addition, the horizontal pipe 31 rotates in the eruption direction with respect to the suction tool main body 1, and the connecting pipe 41 having a bent shape with respect to the horizontal pipe 31 can freely rotate in the circumferential direction. Since there is one flexible pipe, there is a connection pipe 41 to which the hose etc. to be gripped are connected.
On the other hand, the suction port 22 of the holder 3 or the suction port 6 of the suction body 2 can be directed in any direction, making it easy to hold the suction ports 6, 22 in a state facing the surface to be removed. , cleaning can be carried out efficiently.

The rotation of the horizontal pipe 31 and the connecting pipe 41 is effective not only when cleaning floors, but also when cleaning high places such as ceilings. However, if the connecting pipe 41 was fixed to the holder 3, it would be necessary to move the extension pipe in parallel in order to make the suction port 22 face the ceiling surface, which would put a strain on the wrist. However, as mentioned above, the horizontal pipe 31 and the connecting pipe 41 are rotatable, and the position of the suction port 22 relative to the extension pipe is arbitrary, so the extension pipe can be moved in a less tiring state. By gripping it, the suction port 22 can always be opposed to the surface to be removed, allowing more efficient cleaning.

Furthermore, if the connecting pipe 41 rotates without limit with respect to the horizontal pipe 31, especially when cleaning high places such as ceilings,
The holder 3 rotates due to its own weight relative to the gripped extension pipe, etc., and its suction port 22 faces downward, making it difficult to oppose the suction port 22 to the ceiling surface, etc., but as described above, , the fitting portion 42 of the connecting tube 41 is brought into contact with the engaging protrusion 36 of the horizontal tube 31, and the rotation range of the connecting tube 41 is approximately 180°.
Since the regulating part 45 is provided inside, the connecting pipe 41 does not rotate more than necessary. Therefore, even when removing the ceiling surface, etc., the suction port 22 can be kept facing the ceiling surface. It does not become difficult to clean, and cleaning efficiency is improved.

In the above embodiment, the suction device main body 1 is composed of a holder 3 and a suction port body 2 that is detachably attached to the holder 3, but the suction device main body 1 is not divisible in this way but is integrated. It may also be shaped.

〔Effect of the invention〕

According to the present invention, the horizontal pipe is provided in the suction device main body having the suction port so as to be freely rotatable in the front and back direction, and the connecting pipe in a bent shape is provided on the horizontal pipe so as to be freely rotatable in the circumferential direction. This increases the flexibility in the position of the suction port relative to the extension pipe that is connected to this connection pipe and is held during cleaning, so that, for example, when cleaning the floor or ceiling, the suction port faces the scrubbing surface. In addition, by providing a regulating part on the fitted part of the connecting pipe or the fitting part of the horizontal pipe that is fitted into this fitted part, the rotation range of the connecting pipe is restricted. Even when cleaning high places such as ceilings, the connecting pipe does not rotate unnecessarily, making it easier to avoid facing the suction port against the ceiling, and therefore cleaning can be done more efficiently. can.
