Abstract

PURPOSE:To carry the vacuum cleaner while accommodating accessories in an assembled state in the cleaner body by constituting the cleaner so that a holding member attached to an extension tube can be fixed and released to and from a holding member fixing and detaining part provided on plural parts in the extension tube part. CONSTITUTION:By connecting successively a hose 5, an extension tube 6 and a suction port to a cleaner body 1 for containing a motor-driven air blower 2, and inserting the extension tube part 6 into a detaining part 11 of the cleaner body 11, the extension tube part 6 can be held by the cleaner body part 1. Also, a holding member 8 attached to the extension tube 6 is constituted so that it can be fixed and released to and from holding member fixing and detaining parts 9a-9c provided on plural parts in the extension tube part 6. As a result, the cleaner can be carried by containing accessories in an assembled state in the cleaner body, and even in the case it is placed on the floor surface again, it does not occur that the accessories are detached from the cleaner body.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the configuration of a hose holding member of a hose stand type in a vacuum cleaner.

[Conventional technology]

In the conventional hose stand type vacuum cleaner,
As described in Publication No. 3-5954, the holding member provided on the extension tube for locking the extension tube to the vacuum cleaner main body does not require any particular positioning structure for the holding member to be installed on the extension tube. The structure was such that the installation position was determined by the frictional force with the pipe.

[Problem to be solved by the invention]

The above conventional technology does not take into account the locking of the extension tube and the holding member, and if you move the main body while in a hose stand state, the extension tube may slip due to vibrations during transportation, and if you place it on the floor etc. again, the extension tube may slip. Another problem is that the suction port attached to the tip of the extension tube protrudes from the bottom of the vacuum cleaner body, and when the hose is placed down, the holding member comes off from the locking part provided on the vacuum cleaner body, causing the hose to fall down.

SUMMARY OF THE INVENTION An object of the present invention is to provide a vacuum cleaner having a structure that allows an extension tube holding member to be fixed and repositioned.

[Means to solve the problem]

In order to achieve the above object, a locking portion for positioning the holding member at each set position is provided on the extension tube side, and a fitting portion that fits into the locking portion is provided on the holding member side.

[Effect]

The holding member is made of an elastic material, and is adapted to clamp the locking portion on the extension tube side and lock it with the fitting portion on the holding member side.

Therefore, when changing the position of the holding member, you can change the fitting position by resisting the elasticity of the holding member and re-fit it at the desired position, and the position can be changed without shifting from the changed position. There is no.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

The vacuum cleaner body 1 has an electric blower 2 inside. filter 3
A hose attachment port 4 is provided on the outer surface leading to the filter 3, and a hose 5 can be detachably attached to the hose attachment port 4. Further, the tip of the hose 5 is provided with a bending joint 7 to which an extension tube 6 can be connected, and the tip of the extension tube 6 is connected to a suction lower.

Further, the extension pipe 6 has a hose 5. Extension tube 6. A locking member 8 that can be locked to the vacuum cleaner body 1 with the suction lower assembled.
is provided. The locking member 8 has a fitting part 10 that fits into the locking protrusion 9 on the extension tube 6 side, and the locking member 8 fits without coming off due to the elastic force of the locking member 8 itself. It is designed to be able to rotate around the fitting part 10, and the fitting part 1o has an oval shape as shown in FIG. The tip part 8a, which is structured so that it can be articulated and smoothly operated even when the vacuum cleaner body 1 is
It is configured to attach to. Furthermore, when the locking member 8 is not in use, the distal end 8a is stored on the extension tube 6 side so that it can be used without hitting the furniture or the user during cleaning.

On the other hand, the locking protrusion 9 on the extension tube 6 side is provided at multiple locations 9a, 9b, and 9c at different positions, and is locked by opening the tip 8a of the locking member 8 outward depending on the application. Protrusion 9
The fitting part 1o can be removed and moved to another locking protrusion 9.

Since the embodiment of the present invention is constructed as described above, the fitting portion 10 of the locking member 8 is positioned at a position where the lower surface of the suction chamber and the rear surface of the vacuum cleaner main body 1 match, as shown in FIG. When used together with the locking protrusion 9 on the extension tube 6 side, even if you move by holding the handle 12 on the vacuum cleaner main body 1 side, the extension tube 6 from the locking member 8 will not move due to the weight of the suction lower. Even when the vacuum cleaner body 1 is placed on the floor again, the suction lower and the back of the vacuum cleaner body 1 can be placed at the same time, so that the suction lower does not hit the floor first. , the tip 8a of the locking member 8 will not come off the locking groove 11 of the cleaner body 1 and the entire hose 5 will not fall down.

In addition, if the model of the vacuum cleaner body 1 is different and the height from the rear surface of the vacuum cleaner body 1 to the locking groove 11 is different, the locking member 8
If the fitting part 10 is adjusted by moving the locking protrusion 9 of the extension tube 6 to 9a, accessories can be similarly stably stored in the cleaner body 1.

Furthermore, when using extension tubes 6 of different lengths,
When using a different type of suction lower or when storing the suction lower above the floor, the mounting position of the locking member 8 may be moved depending on the parts to be combined.

On the other hand, since the locking member 8 is fitted and attached to the extension tube 6, even if the locking member 8 is subjected to external force etc. even if the extension tube 6 is used alone, the locking member 8 will not come off easily. There is no possibility of losing the member 8.

〔Effect of the invention〕

According to the present invention, the extension pipe and the locking member can be moved to an appropriate location as needed, and can be securely fixed, so that the accessories can be stored and transported in a state where they are assembled in the vacuum cleaner main body.
Even when the vacuum cleaner is placed on the floor again, the accessories will not come off from the vacuum cleaner body.
