Abstract

PURPOSE:To provide an electric floor polisher which is easily handled and kept stable while the maximum tilt angle of a handle being kept horizontally by shifting the center of the central side gear of a decelerator closer to the body front, and recessing the rear of the decelerator into a nearly U-shape. CONSTITUTION:A handle part 14 is rotatably disposed on the rear part of a body 10. A decelerator 12 has two-stage decelerating mechanism, in which the central side gear is made eccentric toward the body front, and the rear part is recessed into a nearly U-shape. Thus, the lower end part 16 of the handle part 14 is fitted in the nearly U-shaped recessed part, so that the handle part 14 can be tilted in almost horizontal direction.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to the tilting angle of the handle of an electric floor polisher.

Conventional technology In recent years, due to changes in the housing environment, the number of floors in ordinary households has been replaced by tatami mats and paper laminates, and wooden floors are increasing, but there was no electric floor polisher for ordinary households as maintenance equipment. .

Conventionally, a similar electric floor polishing machine for commercial use was developed in 1982.
A configuration as shown in Japanese Patent No. 78855 was common.

The configuration will be explained below with reference to FIGS. 6 and 7.

As shown in the figure, a floor polishing machine main body 1 has an electric motor 2 and a speed reducer 3 inside, and a rotary plate 4 on the bottom surface of which a cleaning band or the like is attached. Furthermore, a handle portion 5 is rotatably disposed at the rear of the main body 1. Further, the reducer 3 is a two-stage reduction mechanism, and each gear is provided in a straight line.

In the above structure, since the handle part 6 is made of a pipe or the like, it can be tilted at an almost horizontal angle, so it is effective for cleaning under furniture, etc. Problems to be Solved by the Invention If a commercial electric floor polisher is brought in for home use, the following issues may arise.

In the case of a rechargeable configuration, it is effective in terms of stability to place a battery or the like as a power source at the lower end of the handle portion 5. In this case, the shape of the lower end of the handle becomes larger, so in order to bring the tilting angle of the handle to the horizontal direction, either move the center of rotation of the handle upwards or move it to the rear of the lower end of the handle. There is.

In the case of (2), when the actual floor polisher is moved back and forth, the rotary plate in contact with the floor serves as a fulcrum, causing the main body to wobble back and forth, making operation unstable and hindering cleaning work. Furthermore, stability also deteriorates.

In the case of ■, when the floor polisher is pulled backwards, the front part of the main body lifts up, making operation unstable.

The present invention solves the above-mentioned problems, and provides stable and easy-to-use while maintaining the maximum tilting angle in the horizontal direction so as not to impair the convenience of cleaning under furniture, etc. It provides an electric floor polisher.

Means for Solving the Problems In order to achieve the above-mentioned objects, the present invention is such that the central gear of the reducer is eccentrically positioned toward the front of the main body, and the rear part of the reducer is recessed in a substantially U-shape.

Operation According to the above-described structure of the present invention, the lower end of the handle fits into the substantially U-shaped recess at the rear of the speed reducer, so that the handle can be tilted in a substantially horizontal direction.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 5.

As shown in the figure, the floor polishing machine main body 1o includes an electric motor 11,
It has a speed reducer 12 and a rotary plate 13 on the bottom of which a cleaning pad 22 and the like are mounted. Further, a handle portion 14 is rotatably disposed at the rear of the main body 10. As shown in FIG. 1, the reducer 12 is a two-stage reduction mechanism in which the central gear is eccentric toward the front of the main body, and the rear part of the reducer 12 is concave in a substantially U-shape.

A rechargeable secondary battery 1 is located in the center of the handle part 14.
A connecting terminal 23 for connecting to an external charger 21 is provided at the lower end 16 of the battery 5 for charging the secondary battery 15. The tip of the handle part 14 is a handle part 17 and has a switch knob ε18, and a switch 20 in the handle part 14 is turned on and off via a lever 19 interlocked with the switch knob 18.

To explain the operation in the above configuration, the nozzle part 14
Since the lower end 16 of the is inserted into the approximately U-shaped recess,...
The handle portion 14 can be tilted almost horizontally.

As described above, according to the floor polishing machine of the embodiment of the present invention, the rear part of the reducer located at the lower end of the handle is recessed in a substantially U-shape, so that even if the lower end of the handle is large, the The handle can be tilted almost horizontally.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the rear part of the reducer located at the lower end of the handle is recessed in a substantially U-shape, so that the lower end of the handle is large. The handle part can be tilted almost horizontally, and the convenience of cleaning under furniture, etc. is not impaired, and a stable and easy-to-use electric floor polisher can be provided.
