Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a roller for application / absorption of liquid or dust / cleaning.

<Prior Art> Conventionally, there has been a cleaning roller as shown in FIG.
There was also a paint coating roller of similar construction. These are obtained by fixing the roll (a) used for each of the above purposes to a holding portion (b) that rotatably holds the roll (a). The holding portion (b) includes a shaft portion (c) (c) that rotatably holds the roll (a), and a roll (a).
And a handle (d) for pressing and rolling on the surface of another person. These rollers are, for example, those in which a cylindrical body (e) having an adhesive member on the outer peripheral surface is removably mounted on the peripheral surface of the roll (a) (to be used for applying or absorbing liquid. When it is used for other purposes, use a cylindrical body corresponding to them on the outer peripheral surface). In other words, it has a structure that can be replaced with the same one if it becomes dirty and the cleaning power decreases.

<Problems to be solved by the invention> However, when the target surface such as the surface to be cleaned or the surface to be coated is located at a corner, either the holding part (b) or the shaft part (c) (c) becomes an obstacle. However, the fact is that it is not possible to clean up every corner. In particular, as shown in the figure and the roller described in Japanese Utility Model Application Laid-Open No. S58-122568,
The holding part (b) is coordinated from one end to the other end of the roll,
Since it also serves as a cover for covering a part of the roll, the holding portion hits the corners, and it has been extremely difficult to cleanly handle the corners.

On the other hand, in Japanese Utility Model Publication No. 55-32125, the shaft from the pivotally supporting roll to the handle are integrally formed by bending a thick wire rod, and a locking cylinder made of synthetic resin is provided in the roll. Then, there is disclosed a coating roller that rotatably supports the roll by passing the shaft through the locking cylinder of the roll.

In this coating roller, since the roll is rotatably supported by the shaft via a synthetic resin locking shaft, the roller is pulled out in the axial direction to replace the roll.
Therefore, if the pulling out is stopped midway, the roll can be made to project from the shaft. However, this coating roller is not expected to be used in such a way as to pull out the roll halfway, and it is difficult to appropriately adjust the pulling amount.

Therefore, in the present invention, a roller having a cover arranged from one end to the other end of the roll can be easily selected between a normal use state and a use state suitable for neatly treating every corner. The purpose is to provide a suitable roller.

<Means for Solving the Problems> The present invention is directed to a roll (200) and a holding member (3) (2) that holds the roll (200) in a cantilevered manner only from one end side of the roll (200).

In the present invention, the shaft (202) is slidably inserted in the roll (200). The shaft (202) and the roll (200) are provided with an engaging portion (203) and a receiving portion (204) corresponding to each other. By engaging the engaging portion (203) with the receiving portion (204), the roll (200) is temporarily locked with the sliding resistance increased. And, the position of this temporary locking is at least two positions, that is, the position where the other end of the roll (200) does not project from the cover (3) and the position where the other end of the roll (200) projects from the cover (3). , The receptor (20
The feature is that 4) is provided more than the engaging part 203.

In the present invention, the holding member means a member having a structure that cantilevers and rotatably holds the roll from one end side thereof, more specifically, the shaft (202) and the cover. (3) and a handle (5) (11
2) and are included. In the examples described below,
The cover (3) will be described as the holding portion (3).

<Operation> In the roller of the present invention, the shaft and the roll are provided with the engaging portion and the receiving portion which correspond to each other. It is temporarily locked in a state where the resistance to movement increases. Then, the receiving portion is set so as to be at least two positions, that is, the position where the other end of the roll does not project from the cover and the position where the other end of the roll projects from the cover, at least temporarily. Since many are provided, it can be used in a normal state, that is, in a state where the cover covers from one end to the other end of the roll, and in a corner portion, the other end of the roll projects from the cover. Moreover, the change of both usage states is
This is done by selectively engaging the engaging portions with the receiving portions provided more than the engaging portions, and the desired amount of roll protrusion can be easily obtained.
