Description

[Detailed description of the invention] This invention relates to a floor polishing machine.

A conventional floor polishing machine consists of a main body, a handle shaft whose lower end is pivotably tilted to the main body, and a handle attached to the upper end of the handle shaft.When the handle shaft in a vertical position is tilted at a certain angle, an electric motor is activated. When the switch is turned on, the brush attached to the main body rotates, and the rotating brush washes the carpet and scrubs the floor.

However, during floor polishing work, if there is a step on the floor surface, or if you move the floor polisher after floor polishing work, you need to raise the handle shaft to a vertical position and lock the lock release pedal attached to the main body. After locking the main body to the handle shaft at the section, the handle shaft must be pushed back again and the main body tilted forward and upward to allow the wheels installed at the rear of the main body to roll on the floor. This has the problem of complicating floor polishing work and moving work because it has to be done vertically.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a floor polishing machine that can easily operate the main body in a tilted forward position with the handle shaft tilted, thereby making it easy to perform floor polishing and moving operations. be.

An embodiment of the present invention will be described with reference to FIGS. 1 to 3. In these figures, reference numeral 1 denotes a main body, which incorporates a driving electric motor and a reduction gear. Reference numeral 2 is a floor polishing brush detachably attached to the drive shaft of the main body 1, 3 is a lock release pedal, and 4 is a detergent tank in which the detergent is poured by opening the tank lid 4a. 5 is detergent tank 4
6 is an operating knob for dripping detergent, and 7 is a handle.

To explain the operation of this floor polishing machine, when the user depresses the lock release pedal 3 and tilts the handle shaft 5 by a certain angle, the electric motor is switched on and the brush 2 rotates. Next, when the operating knob 6 for detergent dripping is pressed, the valve attached to the lower end of the detergent tank 4 opens, and the detergent in the detergent tank 4 is guided to the inner surface of the floor polishing brush 2 through the tube and prefoamed. Then, from the dripping hole of the floor polishing brush 2,
and the rotating brush 2 cleans the floor surface F.

Next, details of this embodiment will be described. Reference numeral 8 denotes a bearing provided on the proximal end side of the main body 1, which pivotally supports a horizontal shaft provided at the lower end of the handle shaft 5. 9 is a wire,
One end thereof is connected to the upper part 1a of the main body 1, and the other end thereof is passed through the inside of the handle shaft 5 from the lower end to the upper end. In FIG. 2, reference numeral 5a denotes a long hole provided in the handle shaft 5, the longitudinal direction of which coincides with the axial direction of the handle shaft 5. Reference numeral 10 denotes an operating lever slidably attached to the elongated hole 5a, to which the other end of the wire 9 is connected. 1
Reference numeral 1 denotes a wheel provided at the lower part of the base end of the main body 1, and is mounted above the lower end of the floor polishing brush 2.

During normal use, as shown in Figure 1,
Due to the weight of the main body 1, the main body 1 and the floor polishing brush 2 are in a horizontal position along the floor surface. In that case,
The operating lever 10 is located at the lower end of the elongated hole 5a.
If there is a step on the floor F during the floor polishing operation or when moving the main body 1 after the floor polishing operation,
The operating lever 10 is moved in the direction of arrow A against the weight of the main body 1. Then, the wire 9 is similarly pulled in the direction of the arrow A, and the main body 1 is tilted to assume a forward upward position using the horizontal shaft that is stretched around the bearing 8 as a fulcrum. When the operating lever 10 is moved to the upper end of the elongated hole 5a, the main body 1
is maintained at approximately 90 degrees with respect to the handle shaft 5, and the wheel 11
comes into contact with the floor surface F and becomes movable using the wheels 11.

In this way, with the handle shaft 5 kept in the inclined position, the operating lever 10 located near the grip 7
By simply pulling up, the main body 1 can be tilted forward and the wheels 11 can be brought into contact with the floor surface F, so even if there is a step on the floor surface F or when you want to move it to another location after floor polishing work. There is no need to raise the handle shaft 5 vertically each time, and floor polishing work and moving work can be easily performed. In addition, if the level difference in the floor surface F is slight, the level difference can be overcome by simply pulling up the operating lever 10 slightly and tilting the main body 1 slightly forward.In that case, the main body 1 and the handle shaft 5 Since the main body 1 is not locked, simply by releasing the operating lever 10, the main body 1 can be returned to a horizontal position by its own weight and the floor polishing work can be continued. Note that this floor polishing machine can clean not only the floor surface F but also the bathtub.

As described above, the floor polishing machine of the present invention includes a handle shaft having a handle on the upper part, a main body having a base end pivotally connected to the lower end of the handle shaft and a brush attached to the lower surface side.
a wheel that is attached to the base end of the main body, projects below the base end of the main body, is located above the lower end of the brush, and rolls on the floor while the main body is tilted forward; and an upper end of the handle shaft. a control lever provided on the main body, and a drive mechanism that drives and controls the main body in a forward upward tilt and horizontal position in accordance with the operation of the control lever, and the drive mechanism has one end connected to the main body and is connected to the handle shaft. A wire is passed through the inside from the lower end to the upper end, and the other end of the wire is connected to an operating lever attached to the upper end of the handle shaft so as to be slidable in the axial direction, so that the handle shaft can be tilted. In this state, the main body can be easily operated into a forward and upward tilted position while grasping the handle of the handle shaft, which has the effect of making it easy to perform floor polishing work and moving work.
