Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a roller for applying and absorbing liquid or for dust removal and cleaning.

<Prior Art> Conventionally, there has been a cleaning roller as shown in FIG. There was also a roller for paint application with a similar structure. These are rolls a used for each of the above purposes.
It is fixed to a holding part b which rotatably holds it. The holding part b includes a shaft part c that rotatably penetrates the roll a, and a handle d for pressing and rolling the roll a against the surface of another member. These rollers have, for example, a cylindrical body e having an adhesive member on the outer circumferential surface removably fitted onto the circumferential surface of a roll a (for purposes other than applying or absorbing liquid). When used, a cylindrical body with corresponding members provided on the outer circumferential surface is used). In other words, if it gets dirty and its cleaning power decreases, it can be replaced with the same one.

<Problems to be solved by the invention> In such a conventional roller, in order to increase the ease of replacing the cylindrical body e, the holder b of the shaft part c, which is the rotation axis of the roll a, is attached to the roll c. The shaft part c was held only at one end of the roll a, and the other end of the roll a was released from the holder b. That is, the roll a was held in a cantilevered state by the holding body b. Therefore, the cylindrical body e can be easily replaced from the other end of the roll a released from the holder b.

However, when such a roller is pressed and rolled by someone else, a situation arises in which the cylindrical body e slips off from the released end of the roll a.

For this reason, the prevailing opinion among those skilled in the art was that the ease of replacing the cylindrical body e and the reliable retention of the cylindrical body e were ultimately incompatible.

The present invention aims to solve the above-mentioned conventional problems.

<Means for solving the problems> In view of the above problems, the present invention includes a cylindrical body, a roll serving as the axis of the cylindrical body, a shaft,
and a separate pressing member, the cylindrical body is loosely fitted into the roll, and the roll is rotatable in the circumferential direction so that the cylindrical body has the above-mentioned pressure member at the center of one end face thereof. The roll is pivotally fixed to the shaft, and further has at least one receiving recess formed at an appropriate position on the other end surface, and the pressing member is forcibly fitted into the receiving recess in a detachable manner by appropriate fixing means. The end face of the roll provided with this receiving recess is provided with at least two splits cut from appropriate positions on the inner circumferential surface of the receiving recessed part to the outer circumferential surface of the roll, and the roll is sandwiched between at least these two splits. It is an object of the present invention to provide a roller characterized in that the portion has flexibility capable of being deflected in a radially outward direction of the roll in response to forcible fitting of a pressing member.

<Function> In the roller of the present invention provided with the above means,
The portion sandwiched between the rolls is forcedly fitted by the pressing member and deflects in the radially outward direction of the roll, thereby urging the inner circumferential surface of the cylindrical body and holding the cylindrical body. When the cylindrical body is to be removed from the roll, the cylindrical body can be released by removing the pressing member from the receiving recess and allowing the part sandwiched between the rolls to return to its original position.

<Embodiments> Hereinafter, preferred embodiments of the invention will be described in detail by way of example with reference to the drawings. However, the dimensions, shapes, materials, relative positions, etc. of the components described in this example are not intended to limit the scope of this invention, unless specifically stated. , is merely an illustrative example.

FIG. 1 shows an embodiment of the present invention.

A hollow cylindrical body 1 whose peripheral surface is provided with a dust removal adsorption member such as an adhesive member or an adhesive tape, or a moisture absorption member such as a sponge is removably attached to a separate roll 2. This roll 2 is cylindrical,
Its axis of symmetry (as a rotating body) is penetrated (partially) by the shaft 3. This shaft 3
The roll 2 is rotatably fixed with the rotation axis being the rotation axis. One end of the shaft 3 extends outside the roll 2, and a handle 4 extends from the end of the extended portion 3' (the extended portion 3' of the shaft 3 is limited to the bending direction as shown in Fig. 1). )

A recess 6 is formed on the other end surface 5 of the roll 2, that is, the end surface 5 on which the shaft 3 is not provided. An appropriate number of splits 7 are provided at appropriate positions from the periphery of the end face 5 to the periphery of the recess 6.

Further, the roll 2 is made of an elastic material at least in the area where the split 7 is contained. Of course, the entire roll 2 may be elastic.

A pressing member 8 is fitted into the recess 6 by screwing or other suitable fixing/sliding means.
The fixing/sliding means will be described later.

As the pressing member 8 enters the inside of the recess 6, the peripheral surface of the pressing member 8 or the vicinity thereof presses the inner peripheral surface 9 of the recess 6 and spreads out the portion where the split 7 is inserted. At this time, the cylindrical body 1 is fixed to the roll 2 under the force of the expanded portion. Dividing 7 is effective if there are only a few solid numbers and an even number. This is because a set of two forms a part that can be expanded to the outside. Furthermore, it is more effective if a plurality of splits 7 are arranged radially so that the entire peripheral edge of the end face 5 is expanded.

FIG. 2 shows its cross-sectional view. The inner peripheral surface 9 of the recess 6 is tapered and has a conical shape. The pressing member 8 also has a taper corresponding to the inner peripheral surface 9 of the recess 6. To be more specific, the circumferential side surface 10 of the pressing member 8 is tapered to correspond to the inner circumferential surface 9 of the recess 6 .

With the above configuration, as the pressing member 8 advances inside the recess 6, the peripheral side surface 10 of the pressing member 8 presses the inner peripheral surface 9 of the recess 6, forcing the pressing member 8 to spread out, and the cylindrical body Fix 1. Reference numeral 11 denotes a flange-like portion for retaining the cylindrical body 1 when removed.

Although both the inner circumferential surface 9 of the recess 6 and the circumferential surface 10 of the pressing member 8 have been shown to have a tapered configuration, the present invention is not limited to this. It may be applied. Alternatively, one or both of the recess 6 and the pressing member 8 may be provided with a curved surface at a corresponding position instead of a taper so that the pressing force is directed in the radial direction of the roll 2 (naturally, the recess 6 and the pressing member 8 The same effect can be expected even if one of the two has a tapered surface and the other has a curved surface, and there is no hindrance to such a configuration.)

12 is a knob for rotating the pressing member 8. Reference numeral 13 denotes a threaded portion that fixes and slides the pressing member 8 onto the roll 2.

FIG. 3 shows another embodiment. This is an embodiment in which a plurality of recesses 6 and corresponding pressing members 8 are provided. Here, there are two portions surrounded by the partitions 7, and the recesses 6 and the corresponding pressing members 8 are provided near these portions, but the number is not limited to these. If necessary, there is no problem in increasing the number of recesses 6 and the corresponding pressing members 8.

In the embodiments described above, the threaded portion 1
3 and the knob 12 are configured to be fixed to the pressing member 8, but the present invention is not limited to this configuration, and the screw portion 13 and the knob 12 are integrally configured and the pressing member 8 is fixed to this. You may also allow it to be penetrated without any damage. Configure it like this (of course, turn knob 1)
2 has a structure in which a flange-like portion or the like remains on the surface of the pressing member 8 and is pressed. ), the pressing member 8 does not need to rotate with the rotation of the knob 12, and when viewed from above, it has a shape other than a circle (unlike the one shown in the figure), that is, a polygon, an eccentric circle, an ellipse, etc. It can be formed into any shape. Accordingly, the recess 6 can also be configured to have a cross-sectional shape other than a circle. Further, FIG. 4 shows means for fixing and sliding the pressing member 8 other than screwing. In this case, a pin-shaped body 13' without a thread groove is provided on the pressing member 8 instead of the threaded part 13. This pin-shaped body 13' has a flange-shaped portion 14 or a small protrusion on the side surface of the protrusion. A plurality of spaces 16, 16 wider than the others are provided at appropriate positions of the receiving part 15 that receives the pin-shaped body 13' in the recess 6, and by pressing the pressing member 8, the inner spaces 16, 16 are opened in order. The collar-shaped portion 14 is then received. Such a structure makes it possible to slide and fix it. In this case as well, there is no need to rotate the pressing member 8, and it is possible to take a shape other than a circle when viewed from above.

<Effects of the invention> The reliability of fixing the cylindrical body provided on the outer peripheral surface of the cleaning part has been improved without impairing the ease of replacement.
