Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a roller for applying and absorbing liquid or for removing dust 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 the roll,
When it gets dirty and its cleaning power decreases, it can be replaced with another one. Also, Jikko 60-
The roller handle described in Japanese Patent No. 34389 can also be used in the same manner as the above roller. More specifically, a fitting part (not shown) is provided on the shaft part c, and the outer periphery of the elastic cylindrical part of this fitting part is
By pressing against the inner peripheral surface of the cylindrical body e, the cylindrical body e is fixed to the fitting portion and prevented from coming off. When replacing the cylindrical body, etc., the cylindrical body e is removed by grasping the cylindrical body e by hand and pulling it strongly outward.

<Problems to be Solved by the Invention> However, with the roller shown in the drawings, there is a risk that the cylindrical body e fitted to the roll a may wear and come off while being rotated while being pressed by another person. Further, in the roller handle described in Japanese Utility Model Publication No. 60-34389, the fit between the outer periphery of the cylindrical portion of the fitting portion and the inner circumferential surface of the cylindrical body e becomes loose, and the cylindrical body e comes off. There is a risk. And the cylindrical body e
In order to make it difficult for the cylindrical body to come off, the cylindrical part of the fitting part should be strongly pressed against the inner circumferential surface of the cylindrical body e. This makes it difficult to pull out the cylindrical body e.

<Means for Solving the Problems> Therefore, the present invention provides a cylindrical body 1, a core member 2 that becomes the core of this cylindrical body, and a holding member 3 that holds this core member rotatably in the circumferential direction. The above problem is solved by providing a roller having the following configuration.

In the roller according to the present invention, a pressing member 6 is provided on at least the leading end surface of the core member 2 at an appropriate distance from the leading end surface, and a separate elastic member 8 is provided between the leading end surface and this pressing member. is intervening.
The elastic member 8 has a cylindrical shape expanding into a substantially conical shape, and has a peripheral end 8' on the large diameter side of the substantially conical shape, and a peripheral end 8' on the small diameter side of the substantially conical shape of the elastic member 8. The pressed portion 10 has an opening 8″ in the opening 8″ and receives a pressing force from the pressing member 17 through the opening 8″.
a, 16 and the engaged portion 1 that engages with the pressing member 17
0b, 20. The pressing member 6 is a pressing portion 6 that presses the pressed portions 10a, 16 of the elastic member toward the other end by rotating the pressing member in one direction.
a, 16' and the engaged portions 10b, 20 of the elastic member.
The engagement portions 6b and 19 are provided to engage with the pressing member and pull back the engaged portions 10b and 20 of the elastic member toward the distal end side by rotation of the pressing member in the other direction. When the pressed portions 10a and 16 are pressed, the large-diameter peripheral end 8' of the elastic member 8 expanding in a conical shape expands in the direction of the inner peripheral surface of the cylindrical body 1 to form a cylindrical shape. body 1
is pressed and fixed, and the engaged parts 10b and 20 are pulled back toward the distal end side, whereby the pressing and fixing of the cylindrical body 1 is forcibly released.

<Function> In the roller of the present invention, the elastic member 8 has a cylindrical shape that expands into a substantially conical shape, and has a peripheral end portion 8' on the large diameter side of the substantially conical shape. The member 8 has an opening 8'' on the small diameter side of the approximately conical shape, and the opening 8'' has pressed portions 10a and 16 that receive the pressing force from the pressing member 17, and a portion that engages with the pressing member 17. Since it is equipped with the engaging portions 10b and 20, the pressed portions 10a and 16 or the engaged portion 10 provided in the opening 8″ on the small diameter side
By applying force to b, 20, the substantially conical larger diameter side peripheral end 8' is suitably reduced or expanded in diameter.

Therefore, by rotating the pressing member 6 in one direction, the pressing portions 6a, 16' press the pressed portions 10a, 16 of the elastic member toward the other end. Then, by pressing the pressed portions 10a and 16,
The large-diameter peripheral end 8' of the elastic member 8 that expands into a conical shape
expands in the direction of the inner peripheral surface of the cylindrical body 1 to press and fix the cylindrical body 1.

On the other hand, when replacing the cylindrical body 1, the pressing member is rotated in the other direction. As a result, the engaging parts 6b, 19 of the pressing member are connected to the engaged parts 10b, 19 of the elastic member.
Pull 20 back toward the tip. And the engaged portion 10
By pulling b and 20 back toward the tip side, the pressing and fixing of the cylindrical body 1 is forcibly released.

In this way, in the present invention, since the pressing force of the elastic member 8 against the cylindrical body 1 can be adjusted,
When using the rollers, the cylindrical body 1 is strongly pressed and fixed, and on the other hand, when the cylindrical body 1 is removed for replacement or the like, the pressing force on the cylindrical body 1 can be released.
Furthermore, in the present invention, the engaged portions 10b and 20 of the elastic member 8 are forcibly pulled back toward the distal end, rather than simply releasing the pressing force of the pressing member 6 against the elastic member 8. Therefore, even when paint or the like has hardened, or when the elastic force (restoring force) of the elastic member 8 has been lost due to long-term use, the elastic member 8 can be forcibly removed. By pulling back, the cylindrical body 1 can be easily removed.

<Embodiments> A preferred embodiment of the invention will be described in detail below 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 screw 6 is screwed onto the other end surface 5 of the roll 2, that is, the end surface 5 where the shaft 3 is not provided. This screw 6 has a head 6' of an appropriate size, and is disclosed as a bolt in this embodiment.
It is not intended to be limited to this. It is more effective if a screw hole 7 into which the screw 6 is screwed and received is previously provided on the end surface 5 side.

The above-mentioned screw 6 fixes the elastic holding part 8 to the end face 5 so as to have a degree of freedom in the rotational direction with the symmetrical axis XX of the rotating body as the rotational axis.

The holding portion 8 is formed into a wrapper shape, and an appropriate number of notches 9 are radially formed in the skirt-like peripheral end portion 8'. The skirt-shaped peripheral end 8' side is
It corresponds to the end face 5 side.

By tightening the screw 6 and narrowing the distance between the end face 5 and the end face 5, the holding part 8 interposed therebetween is crushed in the radial direction, and the skirt-like peripheral end part 8' is expanded by the cut. In this way, the peripheral end 8'
The inner peripheral surface of the cylindrical body 1 is pressed and fixed.

On the other hand, a flange-like barb 10 is provided in the opening 8'' on the opposite side to the peripheral end 8' of the holding portion 8. A structure for receiving and engaging this barb 10 is provided. is provided on the back surface of the head 6' of the screw 6.

Figure 2 shows the details. Inside the back surface of this head 6', there is a flange-shaped protrusion provided at the periphery of the cylindrical opening 8'' of the holding part, that is, a barb 1.
A chamber 6'' for receiving 0 is provided.The entrance of this chamber 6'' is formed to be larger than the outer diameter of the cylindrical opening 8'' and somewhat smaller than the outer diameter of the barb 10. The periphery of the opening 8'', that is, the barb 10, is forcibly fitted into the opening 8''. The inside diameter of this chamber 6″ is 10mm
The holding part 8 is set to be larger than the outer diameter of the head 6', and the holding part 8 is rotatable with respect to the head 6'.

The end of this barb 10 becomes the pressed part 10a, and the back side of the barb 10 becomes the engaged part 10b. On the other hand, the wall surface on the distal end side within the chamber 6'' of the head 6' of the screw 6 serves as a pressing portion 6a, and the wall surface on the proximal end side within the chamber 6'' serves as an engaging portion 6b.

Therefore, as the screw 6 is screwed in, the head 6'
The pressing part 6a in the chamber 6'' presses the pressed portion 10a of the cylindrical opening 8'' of the holding part 8, and the large diameter side peripheral end 8' of the holding part 8, which spreads out in a conical shape, is expanded in the direction of the inner peripheral surface of the cylindrical body 1, and the cylindrical body 1 is pressed and fixed. On the other hand, when the screw 6 is unscrewed, the engaging part 6b in the chamber 6'' of the head 6' engages with the engaged part 10b of the cylindrical opening 8'' of the holding part 8. Pull it back toward the tip. As a result, the holding portion 8 is reliably pulled back, and the pressing and fixing of the cylindrical body 1 is forcibly released.

By adopting the above configuration, even if the holding part 8 is damaged (it is made of an elastic material and is prone to breakage such as cracking) and loses its restoring force, the screw 6 can be loosened and retreated. Depending on the situation, it will be released following this screw 6.

In the above configuration, only the threaded portion 12 of the screw 6 is set (formed) upright on the end portion 5 in advance, and a separate nut screwed onto the threaded portion 12 is used as a substitute for the head 6' of the screw 6. A structure using a shaped body may also be adopted.

In particular, if the nut 6' is formed as a lid-like member with a slightly larger diameter and a one-stop closure for the purpose of improving the appearance, it will be effective in improving marketability.

FIG. 3 shows still another embodiment. This diagram is
A state in which the cylindrical body 1 is removed is shown.

A shaft 13 serving as a rotation shaft of the holding portion 8 is formed on the end surface 5. The shaft 13 is formed to be somewhat longer than the height of the holding portion 8. Further, a flange-like barb 15 is formed along the circumference of the open end 14. A wavy portion 16 having a gradually different height is provided at the peripheral end of the opening 8'' of the holding portion 8.

A disc-shaped handle 17 having a corrugated portion 16' corresponding to the corrugated portion 16 on its lower surface is fitted onto the shaft 13. At this time, the inverted hook 15 at the tip of the shaft 13 passing through the center of the disc-shaped handle 17 is hooked at an appropriate position on the upper surface of the disc-shaped handle 17, thereby fixing the disc-shaped handle 17 in a rotatable manner.

With the above-described configuration, the disk-shaped handle 17 is rotated to bring the highest parts of the wavy portions 16' and 16 (ie, the crests of the waves) into contact with each other. At this time,
The disc-shaped handle 17 can press the holding part 8 without changing the distance from the end face 5.

By the way, in the lower part of this disc-shaped handle 17, there is a cylindrical part 18 that protrudes beyond the wavy part 16', enters inside the opening 8'' of the holding part 8, and is located outside the shaft 13.
is provided. An appropriate number of small protrusions 19 are provided at appropriate positions on the surface of this cylindrical portion 18. A groove 20 for receiving the small protrusion 19 is provided on the inner peripheral surface of the opening 8'' of the holding portion 8.

By sliding the small protrusion 19 in the groove 20, the holding part 8 can be forcibly pulled up (the groove 20 is a trajectory traced when the small protrusion 19 slides). ).

In this embodiment (a configuration in which the holding portion 8 is forcibly pulled up), if the corrugated portion 16 and the corrugated portion 16' are unnecessary, they may be omitted.

In particular, the embodiment shown in Fig. 3 was disclosed because when a roller is used with a cylindrical body for removing dust (or for applying paint), the surface to be cleaned (applied surface)
Generally, the cylindrical body 1 is formed to be longer than the roll 2 so that the vicinity of the end face 5 does not get in the way at corners of the floor etc. At this time, the screw 6 inserted deep into the cylindrical body 1 rotates. This is because we took into consideration the troublesomeness of entering further into the depths.

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

Furthermore, by configuring the pressing member with a general screw, the above effects can be obtained using conventionally existing rollers, which is highly effective in terms of cost and ease of manufacture. .

Furthermore, even if the elastic member is damaged and loses its restoring force, it can be forcibly pulled away from the cylindrical body and opened, making it possible to withstand use for a longer period of time.
