Description

  The present invention relates to a hand roller.

  In the case where the paint is applied with a hand roller, it is required to apply the paint so that there are few smears in order to improve the finish of the appearance. However, the appearance finish depends largely on the skill of the operator. An operator with poor skill may cause a difference in the force applied to both ends of the roll of the hand roller, resulting in smearing.

Also, as in Patent Document 1, even in the case of a method (pattern roll) in which a pattern is pressed to form a pattern before the paint on the painted surface is dried (pattern roll), there is a difference in the pattern depth of the pattern roll surface to be obtained. It is necessary to roll the coating surface while pressing the pattern roller parallel to the coating surface and applying an equal force to both ends of the roll so as not to cause pattern spots.
In order to obtain an even pattern roll surface with no pattern spots, it is necessary to press the roll surface parallel to the paint surface, but with the conventional hand roller, when pressing the pattern roller against the paint surface, It was necessary to maintain the orientation of the wrist, arm or body itself holding the roller so that the roll surface was always parallel to the painted surface. Even during the rolling of the hand roller, it is necessary to work without changing the orientation of the wrist or the like so that the roll surface is always parallel to the painted surface, which is a heavy burden on the operator. It was.
Especially if the painted surface is difficult to work, such as the edge of a painted surface, a narrow place, a place with obstacles, or if the painted surface is curved, even a skilled worker The work was not easy, and pattern spots were likely to occur.
Thus, when pattern spots occur on the painted surface, the appearance of the painted surface is degraded. Furthermore, it may be necessary to redo the painting, resulting in a waste of painting time and painting cost.
For example, in Patent Document 2, the amount of paint adhering to the roll can be appropriately maintained by using a single-bubble rubber as the material of the roll, and thus high skill is not required. Both have proposed hand rollers that can reduce smears.

However, in the hand roller of Patent Document 2, after all, it largely depends on the skill of the operator, and it cannot be said that the smear on the painted surface has been greatly improved. In addition, since the amount of paint that can be applied to the roll is limited, there is a limit to the painted surface that can be applied at one time. Furthermore, the hand roller of Patent Document 2 has not yet solved the difference in pattern depth between both ends of the pattern roll.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hand roller that can easily reduce smears on the paint surface or pattern spots on the pattern roll surface without having high skill. .

In order to achieve the above object, the present invention employs the following configuration.
A hand roller comprising a roll, a support portion that supports the roll in a rollable manner, and a handle attached to the support portion, wherein the support portion is rotatable with respect to the shaft of the handle. Hand roller.

  According to the hand roller of the present invention, it is possible to easily reduce smears on the painted surface or pattern spots on the pattern roll surface without having high skill.

  FIG. 1 shows an embodiment of the hand roller of the present invention. The hand roller 10 includes a roll 4, a support portion 6 that supports the roll 4 in a rollable manner, and a handle 7 attached to the support portion 6, and the support portion 6 rotates with respect to the handle shaft 8. It is characterized by being free.

As the surface shape of the roll surface 5 that comes into contact with the painted surface, a smooth surface or a surface on which irregularities are formed can be appropriately selected according to the purpose.
In general coating, a roll surface 5 having a smooth surface shape is preferable in order to uniformly apply a paint.
In the case of forming a three-dimensional pattern such as a pattern roll, the roll surface 5 having a predetermined uneven pattern is preferable in order to form a three-dimensional pattern. By rolling the roll surface 5 onto an undried painted surface, the uneven pattern is rolled onto the painted surface, and a three-dimensional pattern rich in design can be formed. Moreover, as an uneven | corrugated pattern of the roll surface 5, a wave pattern, a spiple pattern (small wave pattern), a polka dot pattern, a stripe pattern etc. can be illustrated, for example.
Examples of the material of the roll surface 5 include piles of fibers such as natural hair, pure hair, mohair, synthetic fiber, and mixed hair, as shown in JIS S 9024, or porous and foamed resins, and other resins. Or metal, wood, paper, etc.
When used for a pattern roll, a roll surface 5 made of a porous body or foam formed from a polyurethane resin, a polyvinyl acetate resin or the like is preferably used. By including water or a water-soluble emulsion flocculant in the porous body or foam, it is possible to make it difficult for the undried emulsion paint to adhere to the roll surface 5 when the coated surface rolls.

  The support portion 6 is connected to both ends of the roll shaft 2 to support the roll 4 so as to be freely rollable. The shape of the support part 6 will not be specifically limited if the roll 4 can be supported so that rolling is possible. The material which forms the support part 6 is not specifically limited, A metal, resin, wood, or those combinations can be illustrated.

The handle 7 is not particularly limited as long as it has a shape that can be gripped with a hand or the like. Examples of the material of the handle 7 include metal, resin, wood, or a combination thereof.
The handle 7 is preferably attached to the support portion 6 so that the handle shaft 8 intersects the roll shaft 2 at a right angle. By doing in this way, since force can be applied along the advancing direction of the roll 4, it can roll on the coating surface smoothly.

Even if the force which acts diagonally with respect to the coating surface from the roll surface 5 is applied to the hand roller 10 of the present invention, the inclination of the support portion 6 is corrected by rotating the support portion 6 with respect to the handle shaft 8. Therefore, even if the orientation of the wrist that grips the handle 7 changes, the roll surface 5 can be pressed in parallel to the coating surface.
Further, the hand roller 10 of the present invention also corrects the inclination of the wrist gripping the handle 7 by rotating the support portion 6 relative to the handle shaft 8 when rolling the painted surface. Even if the direction changes, the roll surface 5 can always be pressed against the coating surface and rolled.
As described above, examples of the hand roller 10 in which the support portion 6 is rotatable with respect to the handle shaft 8 include one embodiment shown in FIGS. 2 and 3. In this embodiment, the joining member 21 having the crown portion 22 and the shaft rod 23 passes through the hole 31 provided in the support portion 6 and the washers 51 and 52 and is joined to the handle 7. . The joining member 21 has a slight play so as to sandwich the support portion 6 so that the support portion 6 can rotate with respect to the handle shaft 8.
Examples of the joining member 21 include bolts such as hexagonal bolts; screws such as tapping, truss, and flat; a combination of nuts and bar screws. In addition, the joining member 21 may be joined to the handle 7 by an adhesive or pressure bonding, and may be joined by screwing the joining member 21 having a thread into a hole 31 having a thread groove. . Moreover, the material of the joining member 21 is not specifically limited, A metal, resin, wood, or those combinations can be illustrated.
The support portion 6 is rotatable with respect to the handle shaft 8, but it is preferable to give some resistance to the rotation. If the resistance of rotation of the support 6 relative to the handle shaft 8 is small, the support 6 rotates carelessly, causing problems such as damage to the painted surface or scattering of paint. Moreover, if the support part 6 rotates carelessly, the positioning at the time of pressing the roll 4 against a coating surface will become difficult.
In order to give resistance to the rotation of the support portion 6, the support portion 6 is supported by the joining member 21 by strongly holding the support portion 6 or using a material that easily causes contact friction to the washer 51 and / or the washer 52. It is preferable to increase the contact friction between the part 6 and / or the joining member 21 and the handle 7. Examples of the washer 51 and the washer 52 include a flat washer, a spring washer, and a coil spring. Examples of the material include elastic bodies such as metal and rubber.

  In order to make the support portion 6 rotatable with respect to the handle shaft 8, for example, as shown in another embodiment of FIG. 4, the shaft rod 24 attached to the support portion 6 and the shaft rod 24 are attached. The hand roller 10 may be provided with the latching 25 that is provided and the recess 32 that is formed in the handle 7 and has the hook receiver 33. The shaft rod 24 is fitted in the recess 32 so that the latch 25 is caught by the catch 33. Thereby, the handle 7 and the support part 6 can be freely rotated without dropping off. The shape of the shaft rod 24 is preferably cylindrical. The recess 32 preferably has a circular cross section in accordance with the shape of the shaft rod 24. The latch 25 may be provided in the middle of the shaft rod 24 other than the attachment to the tip of the shaft rod 24 as shown. However, it is preferable that the shape of the recess 32 and the hook receiver 33 is also a shape that matches the shape of the shaft rod 24 and the latch 25. The shape of the latch 25 is not particularly limited, but it is preferable that at least a part thereof is larger than the width of the cross section of the recess 32 so that the shaft rod 24 does not fall out of the recess 32. In addition, the shaft rod 24 and the latch 25 may be integrally formed. Also in this embodiment, it is preferable to provide resistance to rotation of the support portion 6 by using a washer 53 or the like. The washer 53 can be the same as the washers 51 and 52.

  Furthermore, as in the embodiment of FIG. 5, the hand roller 10 in which the holding member 29 made of an elastic body or the like is embedded in at least a part of the inner wall of the recess 34 and the shaft rod 26 is inserted therein may be used. . In this embodiment, the shaft rod 26 is held by an appropriate elastic force that the holding member 29 has. As a result, the shaft rod 26 can be rotated while receiving appropriate contact friction by the holding member 29, and therefore, contact resistance by a washer or the like need not be used. In this embodiment, since the shaft rod 26 is held by the holding member 29, the retaining rod 25 may not be provided on the shaft rod 26. Furthermore, if the holding force of the shaft 26 by the holding member 29 is set to a holding force that can be inserted and removed by hand, the handle 7 and the support portion 6 can be easily separated as required. For example, the handle 7 can be replaced. Can be performed quickly or in a compact storage. However, the holding member 29 needs to have an elastic force to such an extent that the shaft 26 is not easily dropped off. It is preferable to use a sponge-like or rubber-like resin material for the holding member 29. Alternatively, the handle 7 itself may be formed of an elastic body.

  Furthermore, as shown in the embodiment of FIG. 6, the hand roller 10 having a hole 35 formed so as to penetrate the handle shaft 8 and a shaft rod 28 having a length capable of penetrating the hole 35. It may be. The shaft 28 is inserted into the hole 35. Further, a latch 27 is attached to the tip of the shaft rod 28 so that the handle 7 can freely rotate about the handle shaft 8 without falling off the support portion 6. In this embodiment as well, in order to give a certain degree of resistance to the rotation of the support portion 6, a washer 54 and a washer 55 are provided between the support portion 6 and the handle 7 and between the handle 7 and the latch 27. It is preferable to provide resistance to the rotation of the support portion 6 through the intermediate portion. The materials of the washers 54 and 55 can be the same as those of the washers 51 and 52.

Furthermore, as shown in FIGS. 7 and 8, a hand roller 10 using a rolling bearing 9 may be used. The rolling bearing 9 is configured such that a ring 61 and a rotating shaft 63 are connected via a plurality of balls 62, and is generally called a ball bearing and is often used in various machines. In the present invention, a known rolling bearing can be used. In this embodiment, the rotating shaft 63 is joined to the support portion 6 side and the ring 61 is joined to the handle 7 side. However, the rotating shaft 63 is joined to the handle 7 side and the ring 61 is joined to the support portion 6 side. Also good.
In this embodiment, a washer (not shown) may be used at an appropriate position in order to give resistance to the rotation of the support portion 6, but a rolling bearing 9 having a desired rotational resistance may be used in advance. Moreover, you may use a washer and the rolling bearing 9 together. Although not shown, in addition to the rolling bearing 9, a magnetic bearing using magnetism, a fluid bearing through fluid such as oil, and the like may be used.

  As shown in FIG. 9, the hand roller 10 may have a structure in which the support portion 6 supports only one end of the roll shaft 2. Also in this embodiment, the handle 7 is attached to the support portion 6 by any of the methods described above, and the support portion 6 is rotatable with respect to the handle shaft 8.

Next, the movement of the support portion 6 when the hand roller 10 of the present invention is pressed against the coating surface will be described with reference to FIGS.
As shown in FIGS. 10A and 11A, the hand roller 10 according to the present invention has a support portion 6 with a handle even when a force acting obliquely from the roll surface 5 to the coating surface 100 is applied. By rotating with respect to the shaft 8, the inclination of the roll surface 5 is corrected to be parallel to the coating surface 100 as shown in FIGS. 10 (b) and 11 (b). Therefore, even if the orientation of the wrist that grips the handle 7 changes, the roll surface 5 can be pressed in parallel to the coating surface 100.
Further, the hand roller 10 according to the present invention corrects the inclination of the support portion 6 in accordance with the inclination of the painting surface 100, so that the roll surface 5 can be applied to the painting surface 100 even if the orientation of the wrist holding the handle 7 is changed. It is possible to roll in a state where the parallelism is always maintained.

  Thus, if the hand roller of this invention is used, since the roll surface and a coating surface can always be pressed in parallel, the force added to the both ends of a roll can be equalized. Thereby, even if it does not have a high skill, the coating spot of a coating surface or the pattern spot of a pattern roll can be reduced easily, and, thereby, the coating surface or pattern roll surface of the outstanding external appearance can be obtained. In addition, the hand roller of the present invention can greatly reduce the burden on the operator during the painting operation, and furthermore, since the failure of the painting is greatly reduced, the time and cost required for the painting operation can also be reduced.

  The object to which the hand roller of the present invention is used is not particularly limited, and is suitably used for a painting roller used for painting on inner / outer walls of buildings, eaves, objects, etc., or a pattern roller used for a pattern roll. In addition to these uses, for example, it can also be used for a pressure roller used for attaching wallpaper to a wall surface or the like. Furthermore, it can also be used for dust removal rollers for collecting dust such as floor surfaces, etc., by using the roll surface as an adhesive material.
