Abstract

(57) [Summary] [Purpose] Replace the brush body of the vacuum cleaner with the shaft
Automatic exchange is done only by reverse operation. [Structure] A round pin is provided at the lower end of the shaft of the vacuum cleaner so as to project laterally, and a tapered guide is formed at the tip of the shaft. The shaft and the round pin are detachably inserted at the upper end of the brush body. The brush body is adhered to the floor surface, and the shaft of the cleaner is pressed against the insertion hole of the brush body to complete the attachment automatically. At the time of removal, the brush body is adhered to the floor surface and rotated in the opposite direction to remove it.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in brush attachment of a vacuum cleaner for cleaning floors of buildings and factories.

[0002]

[Prior art]

 Conventionally, a brush is generally attached by a shaft flange and a vault. Also, as a simple attachment, there is known Japanese Utility Model Laid-Open No. 63-9315, in which a protrusion is provided on the shaft side, an insertion hole and a crank-shaped hooking groove are provided on the brush side, and relative rotation is performed manually. It is attached.

[0003]

[Problems to be solved by the device]

 According to the method described above, it is troublesome to incline the mounting portion of the machine body, hold the brush in the hand and insert it, and rotate it to fit the protrusion on the shaft side into the crank-shaped locking groove. Further, when removing the brush, there is a problem that the dirty brush is put on the hand and rotated to remove it.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, in a floor cleaner in which a brush for cleaning the floor is connected to the lower end of a shaft that is rotated in one direction, a round pin is laterally attached to the lower end of the shaft. A tapered guide portion is formed at the tip of the rod, a padding material is elastically attached to the upper part of the round pin by a coil spring, and the shaft is detachably inserted at the upper end of the brush body. The floor cleaner is characterized in that it is configured by providing a thin receiving plate with an insertion hole to allow automatic connection with the shaft.

[0005]

[Action]

 If the brush that has worn out and has dirty water adheres to the floor surface and is directed in the reverse rotation, the round pin of the shaft will move to the insertion hole, and can be removed by tilting the machine. When installing a new brush, place the brush of the present invention directly under the shaft, rotate the shaft and press it, the guide part of the shaft is guided to the center of the insertion hole of the receiving plate, and then The round pin rides on the thin receiving plate and is urged. The operator simply attaches and detaches the brush by simply inclining the aircraft and operating the shaft in the forward and reverse directions.

[0006]

【Example】

 The configuration will be described based on the drawings in which the present invention is implemented. FIG. 1 is a side view showing the whole of a vacuum cleaner 1 embodying the present invention. In this embodiment, a detergent is sprayed and brushed and then dirty water is sucked.

The cleaner 1 is equipped with a brush body 7 at the lower front part, and is supported by a traveling wheel 6 and a guide wheel 8 for work. The operator operates the handle 4 and the panel 3, and detergent (not shown) is injected into the brush body 7 and the squeegee 5 at the rear portion sucks the waste water.

FIG. 2 shows a perspective view of a mounting portion of the brush body 7, which is a main portion. A shaft 9 has a tapered guide portion formed at the tip thereof, and a round pin 10 is laterally projected. A pad 12 is arranged on the upper surface of each round pin 10 and is biased by a coil spring 13. A receiving plate 16 having an insertion hole 14 is fixed to the brush body of No. 7. The insertion hole 14 of the receiving plate 16 is notched so that the shaft 9 and the insertion portion of the round pin 10 can pass through, and a stopper 15 with which the round pin 10 abuts is provided on the back surface to transmit the rotational force of the shaft 9.

FIG. 3 is a cross-sectional view of a main part and is a cross-sectional view in which the brush body 7 is attached to the shaft 9. The round pin 10 on the side of the shaft 9 fixes the receiving plate 16 to the pad 12 by the pressure of the coil spring 13. A motor 17 gives an instruction for forward rotation and reverse rotation by the operation portion of the panel 3. When the shaft 9 is rotated forward from the position shown in FIG. 2 and is inserted into the receiving plate 16 of the brush body 7 adhered to the floor surface, the guide portion 11 is centered and the round pin 10 is inserted to insert the round pin 10. The mounting is completed by riding over the thin receiving plate 16 having a diameter of about ⅓ and making contact with the stopper 15 to rotate.

Since the normal work is a normal rotation, the round pin 10 is driven as it is while being in contact with the stopper 15. When the brush body 7 is worn and needs to be replaced, the round pin 10 moves to the insertion hole 14 and comes off when the brush body 7 is rotated in the reverse direction with the panel 3 kept in contact with the floor surface.

[0011]

【effect】

 With the above configuration, the operator can install and remove the brush body easily by simply instructing the normal / reverse rotation of the panel without getting his hands dirty or bothered.
