Abstract

[PROBLEMS] A commercially available window wiper is almost perpendicular to the target window glass, the wiper is not on the center line with respect to the axis, the force does not enter straight, and the glass surface has streaks or unevenness. Must be rubbed many times. There was also a problem that there was a wiper at the end of the handle, and it was difficult for the force to be transmitted to the wiper.
In order to easily hit an object, the warper is radially angled from the center line of the handle, and at the end of the wiper handle so that the angle of the wiper can be changed toward the object. A fulcrum rotating shaft that rotates and rotates around the fulcrum holding part is provided. Further, play is provided in this part, and the wiper minimizes friction by making point contact between the fulcrum holding part provided on a part of the pipe and the fulcrum rotating shaft. The window wiper or washer, and the roller for painting, which freely rotated 360 degrees under the pipe and always had a function of directing the object at right angles.

Description

Window wiper, washer, painting roller

Window cleaner wipers work with ropes in specialized contractors, so you can use both hands to clean windows. Streaks remain in the window without evenly transmitting the force.

When using an extension stick, the roller for painting is difficult to transmit the force evenly to the tip, and the tip of the handle becomes sticky, and uneven coating and streaks tend to remain.

A commercially available window wiper wipes the window glass at a right angle so that the wiper surface is in contact with the window glass, but it is not on the center line of the shaft, so it is not reliably symmetrical. Therefore, streaks and uneven patterns are attached to the finish.

The place where the handle is held is the power point, but since the distance from the power point to the wiper is far away, the force is difficult to be transmitted, so it is necessary to apply more force and it becomes more unstable.

In order to make it easy to hit the object, provide a radial angle from the center of the handle, and provide a fulcrum so that the wiper is always on the center of the handle, and the point of action is always in line with the fulcrum. The structure can be rotated 360 degrees.

As a result, the force of the power point was transmitted to the branch office by the principle of the lever, and it became a big moment to the action point, the force was transmitted to the wiper at a right angle, and there was no loss of force. In addition, the fulcrum holding part for fixing the fulcrum of the pipe provided directly above the fulcrum rotation shaft is a spherical surface, the contact of the fulcrum rotation shaft is a point contact, and a certain amount of play is provided so that the wiper can be more freely attached to the target glass. The structure is easy to face.

The roller for painting is on the center line of the handle, and a fulcrum rotating shaft that can rotate 360 degrees is provided at the end of the handle so that it always hits the right angle. A fulcrum rotating shaft can be freely rotated by a fulcrum holding part with a circular handle of the handle.

The above-mentioned structure ensures that the wiper hits the glass at right angles, there is no loss of force, and it is possible to work with a small force, a stable force and a large force, and workability and finish are greatly improved. did.

With the above-described structure, the roller is always on the center line of the handle, and always hits the right angle toward the wall of the target surface.

Provide a radial angle from the wiper and the center line of the handle, provide a cylindrical fulcrum rotation shaft at the end of the handle, squeeze a part of the pipe directly above it, and provide a fulcrum holding part. The structure can be rotated 360 degrees in accordance with the movement of the wiper.
By applying the lever principle as a force point to the handle holding part, the force point is rotated 360 degrees around the fulcrum so that the force of the force point hits the object and the action point at right angles.

The fulcrum holding part and the cylindrical fulcrum rotating shaft at the end of the handle are in point contact with each other to provide a play that can move with a minimum of friction so that it can move quickly at right angles to the movement of a small wiper.

The fulcrum fixing shaft and the fulcrum rotation shaft of the fulcrum are fixed by screwing etc., and the rotation of the handle is achieved by providing a semi-spherical fulcrum holding part with a part of the pipe just above the handle fulcrum rotation shaft Since the shaft became point contact and moved freely 360 degrees, it was immediately usable.
Pipe bending can be used immediately with known techniques.
It can be realized in all fields, and its functionality and workability are greatly improved, so it can be used immediately in industry.
