Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vacuum cleaner having a bumper along the side surface of the vacuum cleaner.

Conventional configuration and its problems The conventional configuration of this type of vacuum cleaner is
As shown in the figure, vacuum cleaner body 1 (hereinafter referred to as the main body)
A bumper 3 made of resin, hard rubber, etc. is provided on the side surface to protect a lid 2 that closes an upper opening of a dust collection chamber (not shown) provided in front of the main body 1. Here, the bumper 3 is used for protection to prevent furniture from being damaged during cleaning, and has only the function of protecting the main body 1, so it has little merit in spite of the high cost.

OBJECTS OF THE INVENTION The present invention solves these conventional problems and provides a vacuum cleaner with improved usability.

Structure of the Invention The present invention provides a vacuum cleaner including a main body including a built-in motor, a dust collection chamber provided in front of the main body, and a main body protection bumper provided on the outer periphery of the main body and the dust collection chamber. The main body protection bumper has a generally U-shaped overall shape, and is configured to be rotatable by having both ends thereof pivoted to the main body via a shaft, and furthermore, the main body protection bumper has a shaft supporting side. The bumper support part has uneven parts on the outer periphery,
The body side is equipped with leaf springs that engage with these uneven parts, and this configuration allows the bumper to be used not only for the purpose of protecting furniture and protecting the body, but also for a variety of ways, making it easy to use. Therefore, it is possible to provide a vacuum cleaner with improved characteristics.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figures 2 to 10, 1
Reference numeral 1 denotes a main body containing a motor 12, a cord reel 13, etc., and is closed by the body 14. 15 is a dust collection chamber in which a paper bag 16 is attached;
The lid 17 is closed during use. Reference numeral 18 denotes a substantially U-shaped bumper made of resin or the like and provided so as to surround the main body 11, the upper body 14, and the lid 17. The bumper 18 is provided with a shaft 19, and further has a bumper support portion 21 having an uneven portion 20 formed in a cam shape at its tip. Further, the main body 11 has a plate spring fixing rib 23 that fixes the plate spring 22 facing the uneven portion 20 of the bumper support portion 21.
is provided. Furthermore, a hole 24 is provided in the upper body 14 for inserting the bumper 18.

In Fig. 8, 25 is a hose unit;
26 indicates a floor nozzle.

The above is an embodiment of the present invention. Next, the operation will be explained. When the user lifts up the bumper 18 in front of the lid 17 (arrow in FIG. 2), the bumper 18 rotates around the shaft 19. started to move,
The bumper support part 21 rotates smoothly until the uneven part 20 hits the leaf spring 22. However, after the uneven portion 20 comes into contact with the leaf spring 22, the leaf spring 22
Since it is necessary to rotate the bumper 18 against the force of the bumper 18, the bumper 18 can be rotated with an appropriate click feeling. When the plate spring 22 is inserted into the concave portion of the uneven portion 20, the bumper 18
is in a fixed state and will not rotate with a light force.

By making the bumper 18 not only rotatable but also fixed, the bumper 18 can be rotated almost vertically as shown in FIG.
By placing the hose unit 25 on the hose unit 25 after fixing it, the hose unit 25, which users generally have trouble cleaning up after cleaning, can be supported very easily. There's no need to remove it.

Further, as shown in FIG. 9, if only the floor nozzle 26 is attached to the main body 11 and the bumper 18 is rotated and fixed slightly backward from the vertical position, the main body of the vacuum cleaner becomes shaped like a wheelbarrow. Cleaning can be done simply by applying force in the direction of the arrow without using the hose unit 25, making the hose unit 25 unnecessary.

Furthermore, a hole 2 into which the shaft 19 of the bumper 18 fits
Since numeral 4 is an elongated hole as shown in FIG. 7, the bumper 18 can also be moved in the front and rear directions as shown in FIG. 10, so that it can form a telescopic handle. Therefore, since there is no need to provide a handle, the vacuum cleaner can be made smaller and lighter.

Effects of the Invention As is clear from the above embodiments, according to the present invention, by making the bumper rotatable, it is possible to use it as a hose stand, push it by hand, form a handle, etc., and use it as a vacuum cleaner. This can greatly improve usability. In addition, a bumper support part with an uneven part on the outer periphery is provided on the shaft support side of the bumper, and a leaf spring that engages with this uneven part is provided on the main body side, so that each type of usage can be maintained reliably, making it even better. Usability can be improved.
