In addition, the locking projection 21 formed on the bottom 18 of the holding portion 17 is a recess formed by recessing the bottom 18, and the outer surface of the extension tube 13 is formed.
The holding part 17 and the extension tube 13 may be locked by using the first locking part 26 and the second locking part 27 formed on the 13a as projections protruding from the outer surface 13a.

Next, an example of how to use the electric vacuum cleaner having the above configuration will be described.

As shown in FIG. 7, in the vacuum cleaner 10 in the stored state, the locking projection 21 of the holding portion 17 and the second locking portion 27 of the extension tube 13 are in the locked state, and are inserted into the holding portion 17. The floor brush 14 attached to the tip 13a of the extended extension tube 13 is brought into contact with the floor surface F, and the main body 11 having the rear surface 11c of the cleaner body 11 at the bottom is supported by the floor brush 14 of the extension tube 13 tip 13a. The main body 11 and the extension pipe 13 are stably held in an upright state.

By the way, as shown in FIG. 8A, the extension tube 13 is mounted by pushing the grip body 23 downward and fitting it into the holding portion 17. The extension tube 13 in the holding part 17 that is pushed in slightly strongly
Also, the ridges 22, 22 are slightly deformed to get over the ridges 22, 22 to reach the bottom portion 18, and the main body 11 is inserted in the front-rear direction. By making the distance between the tips of both ridges 22 and 22 shorter than the outer diameter of the extension tube 13, the extension tube 13 fits into the bottom portion of the holding portion 17 with an appropriate click feeling. Depressed handle 23
Is not buried in the recess 19b provided in the side wall portion 19 and does not hinder the fitting of the extension pipe 13, and is urged upward by the spring 25 so that the extension pipe 13 is fixed after being fitted. ,
As shown in Fig. 8B, it returns to the original position and the upper part of the holding part 17
20 will be closed. When using the vacuum cleaner 10, the vacuum cleaner 10 in the upright state is tilted, for example, by holding the upper portion of the extension tube 13. At this time, the extension pipe 13 holds the second locking portion 27 at the holding portion.
17 and the floor brush 14 is separated from the floor surface F and
11 Since it is located on the upper part of the rear surface 11c, the vacuum cleaner 10
It becomes a state of being supported by and becomes movable.

After moving the cleaner 10 to a predetermined position while the extension tube 13 is inserted in the holding portion 17 of the upper surface 11d of the main body 11, the extension tube 13 is advanced from the holding portion 17 toward the rear surface 11c of the main body 11. Then, the extension tube 13 is pushed out slightly strongly along the insertion direction. By being pushed out by a slightly strong force, the second locking portion 27 of the extension pipe 13 is released from the fitting with the locking projection 21 provided on the holding portion 17, and the extension pipe 13 is locked by the locking projection 21. Overcoming the main body 11 Rear surface 11
Move in the c direction. The pushed out extension pipe 13 is locked by fitting the recess of the first locking portion 26, which is provided slightly apart from the second locking portion 27, with the locking projection 21 of the holding portion 17. Then fixed. The extension tube 13 locked and fixed at the first locking portion 26 projects from the rear surface 11c of the main body 11, and the main body 11 and the extension tube 13
When the wheel is tilted toward the front wheel 15, the extension tube 13 inserted into the holding portion 17 is in a state where the floor brush 14 at the tip 13a is in contact with the floor surface F.

Therefore, the vacuum cleaner 10 moves while the floor brush 14 contacts the floor surface F while the extension tube 13 is still inserted into the holding portion 17 of the upper surface 11d of the main body 11 which is in the moving state (shown in FIG. 1). It can be cleaned.

By the way, the locking projection 21, the first locking part 26, and the second locking part 27
In the fitted state, as shown in FIG. 9, the locking projection 21 is formed in a hemispherical shape and the first locking part 26 and the second locking part are formed.
27 has a slope portion 26a having a large inclination angle, and further,
Since each of them is made of synthetic resin, they are deformed according to the pushing force, and the extension tube 13 can be easily moved.

When using the vacuum cleaner 10, the extension pipe 13 is moved so that the floor brush 14 moves back and forth on the floor surface F, but the main body 11 in which the extension pipe 13 is inserted also moves together. At this time, since the back and forth movement of the floor brush 14 is performed by the rear wheel 16, the force for moving the extension pipe 13 is small, and the extension pipe 13 in the locked state with the main body 11 is the same as the extension pipe 13. Since the protrusions 22 and 22 of the bottom portion 18 provided without play between the two blocks prevent the upward movement of the extension pipe 13, the extension pipe 13 in the holding portion 17 may be moved by a light force such as moving the extension pipe 13. It is impossible to move it in the front-back and up-down directions, and the extension tube 13 is maintained in a fixed state.

In this way, by providing a plurality of first locking portions 26,
The inclination angle of the electric vacuum cleaner 10 can be arbitrarily set in accordance with the height of the user or the place of use.

Therefore, just by inserting the power cord of the electric vacuum cleaner 10 into an outlet, the dust collecting hose 12, the extension tube 13, the floor brush 14, etc. are not only assembled and disassembled, but also the extension tube 13 or the dust collection hose is attached to the main body 11. Extension tube with each component such as 12 attached 13
By advancing and inclining, the electric vacuum cleaner 10 can be immediately moved together with the main body 11.

Further, since the holding portion 17 is formed by denting the upper surface 11d of the main body 11, it is possible to reduce the protruding portion of the upper surface 11d, it does not hinder the use, sufficient strength is obtained and damaged. It is difficult, and the shape can be slimmer even when the extension tube 17 is inserted. In addition, since the handle body 23 is provided on the holding portion 17 and the free end of the handle body 23 is prevented from being displaced upward by the stopper portion 24, the extension pipe 23 is fixed to the main body 11.
Even when it is used as it is attached to, the extension tube 13 does not come off from the outside of the holding portion 17, and the handle body 23 also serves as a holding portion, so that the number of parts can be reduced.

The extension tube 13 can be attached to or removed from the holding part 17 by opening the handle 23 provided on the upper part 20 of the holding part 17,
Of course, the extension tube 13 can be detached from the main body 11 and used. The handle body 23 can be operated, for example, by providing a holding release device that can be opened and closed with one touch on the upper surface 11d of the main body 11 by operating a button or the like.

Further, by inserting the extension tube 13 into the holding portion 17 formed on the upper surface 11d of the main body 11 and mounting the extension tube 13 in parallel with and integrally with the main body 11,
Since the occupied space in the vertically standing state can be further reduced, it is possible to store the space in a surplus space between furniture and the like, and the storage space is less restricted.
