<Example of use of an electric vacuum cleaner equipped with a support member>
FIG. 6 is a diagram illustrating an example of a usage state of the electric vacuum cleaner of FIG. 1.
When the floor surface F, which is the surface to be cleaned, is cleaned using the canister-type vacuum cleaner A, for example, as shown in FIG. 6, when the user U is an elderly person, cleaning while standing is burdensome on the body. There is a possibility that it will take a lot of time, and therefore cleaning may be performed while sitting on the floor surface F. Further, the user U may clean in a low posture, such as crouching while peeping under the bed or under the sofa and crawl on all fours. In such a case, when the supporting member 5 is attached to the hand pipe 2a of the electric vacuum cleaner A, the hand pipe 2a is moved in the front-back direction to move the suction port body 4 back and forth through the extension pipe 3, The hand pipe 2a supported by the support member 5 floats above the floor surface F, and the wheels 5bb of the support member 5 roll on the floor surface F.

  Therefore, according to the support member 5 of the present invention, the user U, for example, moves the hand pipe 2a in the sitting posture back and forth to rub against the floor surface F (flooring, folding, carpet, etc.) and the resistance to the forward and backward movement is increased. Even if the existing canister-type electric vacuum cleaner A is used, the hand pipe 2a can be smoothly moved back and forth to improve the usability by solving the problem of the conventional technology that the usability is deteriorated. Further, since the support member 5 can be swung, the user U can easily move the handle 2ab not only in the front-back direction but also in any direction parallel to the floor surface F, which also improves usability. Have contributed.

  Further, in the case of the first embodiment, since the convex portion 2ag of the hand pipe 2a is fitted into the convex portion insertion portion 5ad of the support member 5, the support member 5 rotates the outer peripheral surface of the hand pipe 2a in the circumferential direction. The movement of the support member 5 in the circumferential direction is restricted so as not to move. Therefore, the support member 5 does not unexpectedly rotate in the circumferential direction on the outer peripheral surface of the hand pipe 2a during cleaning, and the wheels 5bb do not laterally shift.

By the way, in the first embodiment, as shown in FIGS. 3 and 6, the hand pipe 2a of the electric vacuum cleaner A has a shape in which the front end opening 2ae side is bent downward toward the front. This bent shape is mainly for making it easier for the user to hold the handle 2ab when cleaning in a standing posture, and the support member 5 corresponds to the bent shape of the hand pipe 2a.
That is, as shown in FIGS. 4 to 6, in the support member 5, the upper surface 51aa of the base portion 5aa of the attachment / detachment portion 5a, which is in contact with the proximal pipe 2a, has a predetermined angle with respect to the lower surface 53aa of the base portion 5a. It is inclined at θ. Along with this, the bottom surface 51ad of the protrusion insertion portion 5ad is also inclined at a predetermined angle θ.

  By configuring the support member 5 as described above, when the suction port body 4 and the wheels 5bb of the support member 5 are brought into contact with the floor surface F, the predetermined angle θ is not provided (the upper surface 51aa is parallel to the lower surface 53aa). The user U can lean the handle 2ab by tilting the rear side (handle 2ab side) of the hand pipe 2a toward the user U in a lower posture (for example, sitting posture). It becomes easier to hold. In addition to that, compared to the case where the predetermined angle θ is not provided, the wheels 5bb can be brought closer to the hand pipe 2a. Therefore, the heights of the hand pipe 2a and the handle 2ab are made lower, and the extension pipe 3 is inclined with respect to the floor surface F. The angle α can be made smaller. Therefore, for example, it becomes easy to insert the suction port body 4 and the extension tube 3 into a narrow gap in the height direction, such as under the living table T, sofa, or bed.

  The support member 5 may be configured to be attachable to the extension pipe 3, but in this case, the weight of the hand pipe 2a side is placed on the hand of the user U, and the wheel 5bb of the support member 5 serves as a fulcrum. Since the swinging of the hand pipe 2a in the vertical direction is allowed, the hand holding the handle 2ab is easily lowered, and then the suction port body 4 is easily lifted from the floor surface F with the wheel 5bb as a fulcrum. Therefore, by mounting the support member 5 on the lower portion (preferably directly below) of the hand pipe 2a on the side opposite to the handle 2ab, such lifting of the suction port body 4 is suppressed and the handle operation of the user U is performed. Is preferred for stability.

FIG. 7: is a figure explaining another usage condition of the electric vacuum cleaner of FIG.
The canister-type vacuum cleaner A removes the extension pipe 3 that connects the connection hose 2 and the suction port body 4, and inserts the suction port body 4 into the front end opening 2ae (see FIG. 5) of the hand pipe 2a of the connection hose 2. The connecting pipe portion 4b can be inserted and connected.
According to this usage pattern, it is convenient for the user U having a low posture (for example, a sitting posture) on the floor surface F to clean his / her surroundings.
