Description

[Detailed Description of the Invention] This invention relates to a rotary adhesive cleaning tool that cleans by adhering dust to an adhesive sheet by rotating it by hand.

In general, there are various types of rotary cleaning tools that adhere to the adhesive sheet through this kind of rotation, but these tools use friction caused by press-fitting between the outer diameter of the rotating cylinder and the inner diameter of the adhesive-wrapped sheet. It was fixed, but
In this case, if the inner diameter of the adhesive-wrapped sheet is larger than the outer diameter of the central rotary cylinder, there is a drawback that it is loose and easily comes off during use, and if the inner diameter of the adhesive-wrapped sheet is small. has the disadvantage that it cannot be used because it cannot be inserted. For this reason, there are various manufacturing inconveniences, such as strict manufacturing control and careful selection of materials that will not cause dimensional errors due to shrinkage or expansion of the product.

This invention is an improvement on the conventional rotary cleaning tool, which has such drawbacks, and its main purpose is to eliminate the large gap between the rotary cylinder attached to the operating rod and the adhesive-wrapped sheet. Or, even if there is a dimensional error, it can be inserted and fixed securely and rotated.

The main structure is that a rotatable cylinder is inserted into a horizontal shaft provided in the operating handle. Several protruding strips made of soft synthetic resin are integrally molded at predetermined intervals on the outer peripheral surface of the rotary cylinder in the longitudinal direction. The inner surface of the core tube of the adhesive-wound sheet is resiliently press-fitted into the protruding strip and fixed to the rotary cylinder.

Next, an embodiment of this invention will be described with reference to the drawings.The hand-operated operating rod 2 is provided with a handle portion 7 on the upper part, and a horizontal shaft 8 on which the rotary cylinder 3 is rotatably fixed on the lower part. A horizontal locking frame 14 for locking the blade protective cover case 4 is formed. Several bendable protrusions 9, 9, made of soft synthetic resin, are integrally molded on the rotary cylinder 3 at predetermined intervals on its longitudinal outer peripheral surface.

Further, on the outer periphery of the rotating cylinder 3, adhesive is applied to various types of paper, etc., and an adhesive cylinder 1 made of an adhesive winding sheet 6 wound around the core tube 5 is inserted from the side. It's summery. Reference numeral 10 indicates a side cover that closes both ends of the rotating cylinder 3. Further, the protective cover case 4 with a cutting edge is formed with an engaging portion 12 on a part of its outer periphery, which can be freely engaged with and detached from the locking frame 14, and dust may adhere to the adhesive winding sheet 6 and prevent adhesion. A cutting blade part 1 serves as a cutting blade to pull out and cut off the adhesive-wrapped sheet 6 when it becomes impossible to do so.
3 is formed in the longitudinal direction.

Next, in the case shown in FIG. 9, a glass cleaner cylinder 15 for cleaning the surface of the glass is installed in place of the adhesive wrapping sheet 6 of the adhesive cylinder 1 that is fitted onto the rotary cylinder 3. .

Further, reference numeral 16 is another embodiment in which a dust removal brush cylinder is equipped with a cleaning brush in place of the adhesive wrapping sheet 6 of the adhesive cylinder 1.

This device has the above-mentioned configuration, and to explain how to use this device, first, when removing dust from the floor, etc., first, remove the protective cover case 4 with a cutting edge from the one shown in Fig. 1 to the side. As shown in FIG. 2, the adhesive cylinder 1 is taken out and placed on the floor or the like and rotated by forward and backward operations of the operating rod 2 to clean off various types of dust. When a lot of dust has adhered to the outer periphery of the adhesive wrapping sheet 6, as shown in FIG. The winding sheet 6 is cut by the cutting blade part 13, and the protective cover case 4 with the cutting blade is laterally removed again to expose the new surface of the adhesive winding sheet 6, and the cleaning operation is performed again. .

As described above, this invention has excellent operational effects in that the adhesive cylinder for adhering dust can be easily and reliably attached and detached, and it can be elastically damped and rotated smoothly. By integrally molding several protruding strips made of soft synthetic resin at predetermined intervals on the outer peripheral surface in the longitudinal direction of the rotary cylinder, the protruding strips are formed on the inner circumference of the adhesive cylinder. It can be easily press-inserted and fixed without bending when it hits a surface, and even if there is an error in the inner diameter of the adhesive cylinder, it can be completely absorbed and fixed, and the protruding strips of soft synthetic resin Since the inner surface of the adhesive cylinder is cushioned and pressed, it can contact the cushioning floor surface such as a carpet with sufficient contact, and the dust contained inside can be reliably adhered and cleaned. It has a useful effect. In addition, the protruding strip elastically presses against the core tube of the adhesive-wrapped sheet of the adhesive cylinder to prevent slipping and detachment, and allows the adhesive cylinder to be easily removed and replaced at any time. This has the practical effect of being able to always clean with a clean adhesive winding sheet. Furthermore, the engaging part 12 provided on the outer periphery of the protective cover case with a cutting edge is fixed to the horizontal locking frame of the operating rod when not in use, reliably protecting the adhesive cylinder and preventing it from rotating easily. It has the effect of preventing In addition, the cutting blade provided on the outer periphery of the protective cover case with a cutting blade can easily cut the stretched adhesive-wrapped sheet by fitting from the side into the adhesive cylinder with dust attached. It has a useful practical effect.
