Abstract

(57) [Summary] [Purpose] The electric polisher used in buildings and the like is a very heavy cleaning tool, and the work on the stairs is quite labor intensive and the shape is likely to damage the stairs. In order to solve the drawback, [Structure] Connect the power machine body and the work handle with a handle as shown in the figure (at a position other than the caster, which has a fixed point that acts as a fulcrum of the lever). ] With a small amount of power, a heavy electric polisher can be used to smoothly move up and down stairs with the attached casters.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shape improvement of an electric polisher for cleaning work.

[0002]

[Prior art]

 Generally, electric polishers used in buildings and the like are heavy work tools that efficiently and continuously clean large floors. A sturdy handle will damage the stairs.

In addition, in the previous invention in which the mounting position of the wheel and the like is devised (see the actual opening 01-33958 and the actual opening 02-37059), the wheel is always the lever fulcrum, like the conventional tool. There is. Therefore, continuous cleaning work that involves raising and lowering the stairs is extremely heavy work and is one of the causes of worker back pain.

[0004]

[Problems to be solved by the device]

 Except for the above-mentioned drawbacks, this device uses the same electric polisher for continuous washing work on stairs after floor work, and uses it gently with a little arm force instead of waist. The shape was devised so that

[0005]

[Means for Solving the Problems]

 Figure 3 shows the shape of a conventional floor cleaning polisher. The caster serves as a fulcrum for the lever during both work and movement. Now, if the shape of the handle A is changed to the support part c and the joint part b that can move circularly as shown in Fig. 1, the tip of the support part C, which is different from the caster, is lifted when the stairs are moved up and down. When used as a fulcrum, the power machine body can move smoothly along the casters in the vertical direction.

[0006]

[Embodiment] Therefore, as shown in FIG. 4, when the tip end of the pillar c is erected on the stairs one step higher than where the machine body is placed, and a slight upward turning force is manually applied to the handle, the lever is applied. The heavy machine body will rise smoothly along the casters in the direction of joint b.

In addition, when the tip of the column c is set on the same plane slightly away from the machine body and the braking force in the same direction as when raising the column c is manually applied to the handle, the machine body is caster down one step to the caster. You can also smoothly descend along.

[0008]

[Effect of device]

 For example, if this polisher is manufactured with the dimensions shown in Fig. 4 (unit: cm), it can be lifted and lowered with about 30% of the weight of the machine body.

By using the polisher having the above-described shape, the heavy labor that puts a strain on the waist is reduced, and the cleaning work including the stairs can be efficiently performed with the same tool without damaging the stairs. Become.
