Description

[Detailed description of the invention] (Field of industrial application) The present invention is a floor suction device which has a rotating brush body and a suction device body which has a drive source for driving the brush body, and a connecting pipe rotatably attached to the suction device body. Regarding.

(Prior Art) This kind of floor suction tool has been disclosed in Japanese Patent Application Laid-open No. 132664/1982, but in this suction tool, the rotating and stopping mechanisms of the connecting pipe to the main body of the suction tool are separate. Because of this, the structure was complicated and the cost was high.

(Problems to be Solved by the Invention) The object of the present invention is to provide a simple structure in which the connecting pipe can be easily rotated and stopped relative to the suction tool body.

(Means for Solving the Problems) The floor suction tool of the present invention includes a suction tool main body having a rotating brush body, a drive source for driving the brush body, and moving wheels, and a suction tool body that is rotatably mounted on the main body. A brake comprising a supported connecting pipe, an arcuate cam part formed at the lower end of at least one side of the pipe and abutting the axle of the wheel, and an arcuate notch part continuous with the cam part and engaging with the axle. It is equipped with a board.

(Function) With the above configuration, when the arc-shaped notch of the brake plate is engaged with the axle, the connecting pipe is held in a substantially upright state, and when the cam portion of the brake plate is brought into contact with the axle, the connecting pipe is rotated. It becomes possible.

(Example) 1 is a suction tool main body, which forms a box body 4 with a main body case 2 and a bottom plate 3, and has a suction port 5 provided in the front part.
A rotary brush body 9, which has a brush 7 and a batter 8 formed in a spiral shape, is rotatably supported in the elongated suction chamber 6. Reference numeral 10 denotes an electric motor disposed near one side of the rear portion of the box body 4, which rotates the rotary brush body 9 via a belt 11. Reference numerals 12 and 12 denote a pair of moving wheels, which are pivotally supported on an axle 13 provided at the rear of the box body 4.

Reference numeral 14 denotes a flexible bellows pipe 16 which is a connecting pipe to a vacuum cleaner main body (not shown) rotatably supported in a recess 15 formed between the moving wheels 12, 12.
It is connected to a suction hole 17 formed at the center of the back surface of the suction chamber 6.

Reference numerals 18 and 18 refer to a pair of rollers protruding from an opening (not shown) in the bottom plate 3 formed near the rear of the suction port 5, and the rollers are connected to support ribs 19, 19 provided on the lower surface of the main body case 2 and a fixing plate. It is attached to a roller pivot shaft 21 supported by 20.

On both sides of the lower part of the connecting pipe 14, there are provided support shafts 22, 22 for the recess 15, an arcuate cam portion 23 integral with the base of the support shaft, and an arcuate notch portion 24 continuous to the cam portion. Brake plates 25, 25 are formed, which brake plates are adapted to come into pressure contact with the axles 13 of the moving wheels 12, 12.

The axle 13 is a support shaft 22, 2 of the connecting pipe 14.
It is held between elastic shaft holding plates 27, 27 extending from support fittings 26, 26 supporting the main body case 2, and a support rib 28 formed protruding from the main body case 2. It comes into contact with the provided brake plates 25, 25 and moves up and down within the range of elastic deformation of the shaft holding plate 27.

In other words, under normal use, 2 in Figure 3.
As shown by the dotted chain line, the connecting pipe 14 is used at an angle between 30° and 70° with respect to the floor surface, and at this time, the axle 13 is pushed down by the cam portion 23 of the brake plate 25. Also, when storing or temporarily stopping cleaning and leaving the floor suction tool, the connecting pipe 14 can be rotated more than 90 degrees with respect to the floor as shown by the solid line in Figure 3, and the arc-shaped notch in the brake plate 25 can be rotated. 24 engages with the axle 13 to prevent the connecting pipe 14 from tilting.

(Effects of the invention) Since the floor suction device according to the present invention is constructed as described above, the structure is simple, and moreover, no shock is applied to the connecting pipe during rotation operation.
In addition, the pipe can be rotated and locked smoothly, improving usability.
