Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bumper mounting device for a vacuum cleaner that mounts a band-shaped bumper molded from rubber or soft vinyl chloride to the wall surface around the nozzle.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings. In the figure, 1 is a vacuum cleaner body with a built-in electric blower 2, 3 is a dust collection part with a detachably built-in filter device 4, which can be engaged with the vacuum cleaner body 1 with a buckle 5, and a connecting hose 6. It has a connecting portion 7 that allows for free joining. 8
is a trolley, with a handle part 9 formed in a substantially U shape, casters ~1o, and rollers 4$11. It is composed of a frame part 13 on which a roller 12 is arranged, and the handle part 9 has a
A hanging part 14 for suspending the vacuum cleaner body 1 is provided. Reference numeral 16 denotes an electric blank part constituting the power nozzle. A mouth 19 is formed. 20 is a rotating bluff, and bristles 21 are implanted in a substantially helical shape, and the dust suction chamber 1 is
8 to maintain an appropriate amount of hair 21 coming out from the dust suction port 19. 22 is part of Guri, rotating bra'/20~
The belt 23 receives the rotating force of an electric motor 240. The 1U rotating brush 20 has a hollow cross-section, and the fixed shaft 26 (in L) is press-fitted with a ring (not shown) at both ends. (I'm sorry to divide the dust collection ¥18 into three equal parts (I″L
They are provided at two locations at each location, and one end forms a connection port 27 that connects to the connection hose 6. Reference numeral 28 denotes a substantially U-shaped y1 freely lowerable arm whose longitudinal center is rotatably supported on the side surface of the frame portion 13; f1: Electric 1 protruding towards 1u11
The suction of the 97 part 16 is connected to the mounting part 29 at the rear of the Jf2 16. The mounting part 29 has a bearing part 29' which is formed into an elongated hole in the upward F direction on the side surface, and is slidably fitted into the shaft part 28' and the bearing part 29'. The rear of the arm 28 is a power nozzle lifting part 28'', near which a petal 30 is rotatably supported and a spring 31 is fixed.

Betaru 3o has an abbreviated shape and one side has an inverted shape notch 3
0', which is attached to the frame part 13 and engages with the stopper 32, and one side has a foot pedal part 30''.
It is formed in one piece. 33 is the suction port T17, l-
wall +fn 17' A belt-shaped bumper molded from rubber or soft vinyl chloride, with a plum southern part 33' formed in a substantially U-shaped cross section on the outside and a hook 33'' on the inside, 34 is a hook 33 of the bumper 33. The stop plate is molded into a U-shape at the tip to accommodate the
By lifting the portion 33' and screwing in a screw 43 from the front side of the nozzle, it is fixed to the inner surface of the rising wall surface 17', thereby attaching the bumper 33. 36 is R20~R
It has a curved surface of 30 mm and is formed at the corner of the wall surface 17'. 36 is a convex portion attached to the curved surface 36, and is located in the inner space of the buffer portion 33' of the bumper. 37 is a roller supporting the electric brush, 38 is an exhaust port, 39 is an electric brush/electronic supply flag and cord, 40 (d, total power supply IJ)
C supply plug, outlet, 41 is the total power switch, 4
2 is a magnet body.

With the above configuration, when transporting the vacuum cleaner for cleaning, move the electric bluff section 16 to the bevel 30. By the lifting mechanism by the arm 28, step on the power nozzle lifting part 28'' at the rear of the arm 28 and lift it like a saw, and connect the inverted-shaped cutout hole 30' provided in the betaru 3o and the frame part 13. The shaft portion 32 is used for locking.

Furthermore, by stepping on the foot pedal 3σ' of the Cj and beta 30 from the above-mentioned position in the cleaning state, the beta 3o is unlocked and the electric motor 797 portion 15 is grounded. Next, connect it to your mental image, run it, and clean the carpet.

The dust flows from the rotary bra/2o through the intake port 26 and the connection boss 6, and is collected in the dust collecting section 3 by the filter device 4.

The dust collection part 3 is removably engaged with a buckle 6.
, remove the filter device 4, and remove dust.

Moreover, the electric plan part 16 is not completely fixed to the arm 28, and as shown in FIG.
IJJ if it can rotate freely using 8' as a fulcrum.
It's Hi.

As is clear from the above embodiments, the vacuum cleaner bumper mounting device of the present invention fixes the bumper mounting parts and screws without exposing them to the outside through the cut-out portion of the bumper, thereby preventing them from being stuck in place. In addition to being lightweight, the screws for fixing the bumper can be tightened from the outside of the nozzle, making it easy to attach and detach after assembling the main body. Therefore, the shape of the bumper is simple, extrusion molding is possible, and the mold cost is low.Furthermore, the adhesion strength of the IL plate of the bumper can be adjusted by changing its width. By making the corner of the nozzle a curved surface and providing a convex portion here, deformation of the bumper can be reliably prevented.
