Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a highly efficient window cleaning aid suitable as a window cleaning tool.

Conventional Technology and Problems Conventionally, window glass cleaning has been done by applying a cleaning solution onto the glass and wiping it off with a Com wiper, or generally by polishing it with a cloth. However, while high-rise buildings and the like are cleaned by specialized companies riding on gondolas, it is difficult to clean the window glass of ordinary homes, school buildings, or buildings that are not suitable for installing gondolas. In most cases, the worker leans out of the window and applies force to the glass surface from the outside to the inside while cleaning, making it extremely difficult to maintain balance. Therefore, there is a danger of falling, especially from the second floor or above, and accidents are common. In addition, to prevent such dangers, there is a method of attaching a cleaning tool to the end of a long stick and wiping from the outside, but it is difficult to apply force and requires careful attention to the cleaning by focusing on heavily soiled areas. It had some drawbacks, such as being difficult to wash.

Purpose of the invention Therefore, the object of the present invention is to provide a safe and efficient window glass cleaning aid without having to lean out of the window.

Structure of the Invention For this purpose, the present invention includes a handle body formed in a substantially U-shape from an elastic plate material, a pair of inwardly opposing recesses near both ends of the handle body, and a pair of recesses facing each other inwardly. A pair of through-holes reaching up to The object of the present invention is to provide an auxiliary tool for cleaning window glass, characterized in that the pair of pad units are fixed to the handle body by screwing with the screw portions, and the knob is attached to the handle body, and further The main points are that the bent portion of the handle body is made of a highly elastic material, and that the pad unit is detachable.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

1 and 2 show a window cleaning aid according to the present invention. The code 1 in the figure is the handle body,
The plate-like member is formed into a substantially U-shape, which itself has spring properties, and is formed in advance so that both ends are pressed against each other with a constant force. The handle body 1 is desirably molded from synthetic resin, but may also be formed by pressing a sheet iron plate. The gap 2 has a width area wider than the size of the window frame 9 that holds the window glass 3, and allows the handle body 1 to move freely. A pair of pad units 4, 4 are mounted near both ends of the handle body 1 so as to face each other inwardly. As shown in FIG. 3, the pad unit 4 has a pair of recesses 11, 11 and a pair of through holes 12, 12 formed on the inside near the tip of the handle body 1, and the pad unit 4 shown in FIG. The base part 41 of the base part 41 is inserted, and the screw part 41 of the base part 41 is screwed into the female screw part 411 of the base part 41 with the bolts 5 and knobs 6, respectively.

The pad unit 4 has a sponge pad 42 for washing with water, a brush-like pad 43 for finishing, etc. attached to one side of the base 41, and these can be replaced at any time. In FIGS. 1 to 4, the pad unit 4 is circular in shape, but as shown in FIG. It is also possible to have the padding spread over the corners of the window frame.

Furthermore, in order to increase the elastic force of the handle body 1, the bent portion 14 of the handle body 1 may be formed of a plurality of wire springs 7, as shown in FIGS. 6a and 6b.
Alternatively, it may be formed of a plate spring 8, which increases the elastic force and enables efficient cleaning of the glass.

In addition, as a method of operating the window glass cleaning aid of the present invention, as shown in FIG. 2, hold the window glass 3 so that the knob 6 is located inside the window,
Just by holding it and moving it around, you can clean both the front and back of the glass at the same time while staying inside the window.

Alternatively, the user may hold the bent portion 14 of the handle body 1 together with the knob 6 and move the knob 6 to clean the window glass with the pad unit 4.

Effects of the invention As explained above, according to the invention, pads are attached to both ends of the handle body, which are made of plate-like members formed in a substantially U-shape, facing inward, and both pads have a certain clamping angle. Since it is set using piezoelastic force, when cleaning the window glass, you can spread the handle body with your hands, pinch the window glass, and set it, and then you can clean by simply moving the knob and the handle body by hand. Therefore, not only is there no danger of leaning out of the window to clean as in the past, but the pads clamp the window glass using the spring force of the handle body, so the operator does not have to apply any special force. By simply moving the handle body, the inside and outside of the window glass can be cleaned at the same time.

Also, when cleaning window glass, the pad unit is brought into contact with the window glass and the work is done by sliding it, but the friction between the pad unit and the window glass requires a considerable amount of force to move the pad unit. I need. However, in the present invention, the knob and the pad unit are at the same position relative to the handle body, so when cleaning a window glass, if you hold the knob and the bent part of the handle body and move the knob, the movement moment of the pad unit will be reduced. Since it is large, the knob can be moved with relatively light force. This allows the pad unit to be easily slid onto the window glass surface, improving work efficiency.

Furthermore, since the knob and pad unit can be attached to the handle body at the same time, the number of assembly steps is reduced and the structure is simplified.
