Abstract

PROBLEM TO BE SOLVED: To provide a roller handle which can maintain a high working efficiency by reducing coating waste even when provided with two rollers.SOLUTION: The outer diameter of the tip of a rotating shaft 33a is made smaller than that of another part to form a step part, and the inner diameter of a bearing part 43 is made larger than the outer diameter of the tip of the rotating shaft 33a, and smaller than the outer diameter of a part other than the tip of the rotating shaft 33a. A head part 4 is rotatably supported around the rotating shaft 33a by screwing a nut 45 with the tip of the rotating shaft 33a penetrating through the bearing part 43 to project from the bearing part 43. Thus, in a state that the head part 4 is separated from a coating object region, the head part 4 can be rotated around the rotating shaft 33a, while in a state that the head part 4 is brought in contact with the coating object region, a gripping part 2 can be oscillated around the rotating shaft 33a.

Description

  The present invention relates to a roller handle that supports a roller that is impregnated with a coating agent such as a paint so as to coat a portion to be coated such as a wall and a wall.

  When painting the outer wall of the building or the part to be painted such as a wall, a cylindrical roller with raised peripheral surface is rotatably attached to the head part of the roller handle, and the roller is impregnated with paint in that state. Thereafter, the grip portion of the roller handle is gripped, and the roller is brought into rolling contact with the surface of the portion to be coated. Such a roller handle has been developed to support the following two rollers in order to improve painting efficiency (see Patent Document 1).

  FIG. 7 is a perspective view showing how the roller handle described in Patent Document 1 is used. The roller handle 11 includes a handle portion 130 made of a metal rod-like material, and one end portion of the handle portion 130 is fitted with a tubular material having an appropriate length so that a gripper is held by an operator. 120. On the other hand, the other end side of the handle 130 is bent at a right angle.

  On the other end side of the handle portion 130, two roller support rods 141 and 141 arranged in a direction orthogonal to the handle portion 130 are arranged in parallel to each other at an appropriate distance in the axial length direction of the handle portion 130. In addition, one end portions of both roller support rods 141 and 141 are connected to each other by a rod-like connecting portion 133 arranged so as to have an appropriate elevation angle with respect to the axial direction of the handle portion 130. The connecting portion 133 is supported by a rod-like support portion 132 that is suspended from the other end portion of the handle portion 130, and thereby, between the roller support rods 141 and 141 connected by the handle portion 130 and the connecting portion 133. Are stepped. The connecting portion 133 and the roller support rods 141 and 141 constitute a head portion 140. After the cylindrical rollers R and R are fitted on the roller support rods 141 and 141, respectively, the roller support rods 141 and 141 are connected to each other. By attaching a U-shaped stopper 146 to the other end, the rollers R and R are rotatably supported.

  However, in such a roller handle 11, the angle of the head portion 140 is fixed during the painting operation. For example, when the worker paints an area lower than his / her height, the position of the head portion 140 is changed. In order to rotate 180 °, the roller handle 11 has to be changed, which causes a problem that coating efficiency is reduced and coating unevenness is likely to occur. Therefore, the following roller coating machine is disclosed in Patent Document 2 described later.

  FIG. 8 is a side view showing a usage mode of the roller coating machine disclosed in Patent Document 2, in which 170 is a cover having a trapezoidal shape in a side view. The cover 170 has a rectangular shade shape. In the cover 170, two support shafts 141 and 141 penetrating opposite side walls are installed at an appropriate distance in the depth direction of the cover 170, and both the support shafts 141 and 141 are cylindrical. Each of the rollers R and R is rotatably fitted. Two small pieces 171 (171) are erected at a substantially central position of the ceiling wall of the cover 170 with a distance in the width direction of the cover 170, and a pin 172 is provided between the small pieces 171 (171). It is constructed so as to be orthogonal to the depth direction. The tip of the handle 130 is connected to the pin 172 so as to be rotatable around the central axis of the pin 172, so that the angle between the cover 170 and the handle 130 can be changed.

  In such a roller coating machine 12, since the angle between the cover 170 and the handle 130 can be changed, even when the worker paints an area lower than his height, An operator can perform painting work continuously without changing the handle 130 of the roller coating machine.

  However, in any case described above, when the two rollers R and R are impregnated with the paint, both the rollers R and R must be immersed in the paint. In the latter case, the head part 140 of the roller handle 11 and the cover 170 in the latter case are immersed in the paint, and the paint is wasted by that amount, while the paint adhered to the head part 140 or the cover 170. In order to prevent the ink from falling into the area to be coated, the paint adhering to the head part 140 or the cover 170 must be cut off sufficiently, and there is a problem that the working efficiency is lowered.

  The present invention has been made in view of such circumstances, and provides a roller handle that can reduce the waste of paint and maintain high work efficiency even when two rollers are provided.

  (1) The roller handle according to the present invention has a handle between a gripping part gripped by an operator and a head part provided with two support arms each supporting a roller impregnated with a coating agent in parallel with each other. The head portion is configured to be rotatable about a rotation axis passing between both support arms.

  The roller handle according to the present invention includes a grip portion that the operator grips, and a head portion in which two support arms that respectively support the roller impregnated with the coating agent are provided in parallel. The grip portion and the head portion are connected by a handle portion. The head portion is configured to be rotatable around a rotation axis that passes between both support arms. Here, the rotation shaft may be configured in parallel with both rollers, or may be configured to intersect with both rollers.

  In such a roller handle, the operator grips the grip portion and immerses the roller located at the tip of the roller attached to each of the support arms of the head portion in the coating agent in the container. As a result, the roller is impregnated with the coating agent. When the roller is sufficiently impregnated with the coating agent, the operator pulls the roller out of the coating agent and drops excess coating agent from the roller to remove it.

  Next, for example, the worker collides the roller against the inner wall of the container and rotates the head portion around the rotation axis to position the other roller at the tip. Then, after performing the same operation as before, the other roller is sufficiently impregnated with the coating agent, and then the roller is pulled out from the coating agent, and the excess coating agent is dropped and removed from the roller.

  Thus, in the roller handle of the present invention, the portion immersed in the coating material can be substantially limited to the portions of both rollers, so that waste of the coating material can be reduced as much as possible. Similarly, since the portion immersed in the coating material can be substantially limited to the portions of both rollers, the time required to remove the excess coating material can be shortened as much as possible. Even if it is provided, high working efficiency can be maintained.

  On the other hand, any of the two rollers can be positioned at the tip without changing the gripping portion, so that the consumption rate of both rollers is the same by replacing the roller positioned at the tip at an appropriate timing. The life of both rollers can be extended.

(2) The roller handle according to the present invention is characterized in that the rotation shaft is configured in parallel with both support arms.

  In the roller handle according to the present invention, the rotation shaft passing between the two support arms is configured in parallel with the two support arms. Therefore, when the head unit is separated from the region to be coated, the head unit is By rotating around the rotation axis, the waste of the coating agent can be reduced as much as possible while maintaining high working efficiency as described above. On the other hand, when the head part is in contact with the area to be coated, the gripping part can be swung around the rotation axis, so that the operator can move from a relatively higher area to a lower position without holding the gripping part. It is possible to carry out painting work continuously in the area.

  (3) In the roller handle according to the present invention, the head portion has the support arms erected on both ends of the rod-like base arm, and the tip of the handle portion is located at a midway position in the longitudinal direction of the base arm. It is characterized in that it is rotatably connected to the part.

  In the roller handle according to the present invention, the head portion is formed in a U shape by standing up support arms for supporting the rollers at both ends of a rod-like base arm. And it is rotatably connected with the front-end | tip part of a handle | pattern part in the middle position of the longitudinal direction of the base arm which comprises this head part, Preferably in the center position of the longitudinal direction of a base arm. As a result, the roller handle can be made as simple as possible, and the manufacturing cost can be reduced.

  (4) In the roller handle according to the present invention, the tip end portion of the handle portion is bent so as to be parallel to the both support arms, and is formed as a rotation shaft. Is provided with an annular bearing for inserting the tip of the handle, and the tip of the handle is inserted into the bearing so that the base arm and the tip of the handle are rotatably connected. It is characterized by being.

  In the roller handle according to the present invention, the distal end of the handle is bent so as to be parallel to both support arms of the head, and is used as a rotation shaft. An annular bearing portion through which the tip end portion of the handle portion is inserted is provided at the position, preferably the center position in the longitudinal direction of the base arm. And the tip part of the handle part is inserted into the bearing part, and the base arm of the head part and the tip part of the handle part are rotatably connected. Thus, since the tip of the handle is only bent, it is simplified as much as possible, and interference between the tip of the handle and the portion to be coated can be avoided during the painting operation. .

(Embodiment 1)
Hereinafter, the roller handle according to the present invention will be described in detail with reference to the drawings. Note that the roller handle described in the present embodiment is an example for explaining the gist of the present invention, and the present invention naturally includes modifications without departing from the gist.

  1 to 3 are a front view, a plan view, and a side view of a roller handle according to the present invention, in which 3 is a handle using a rod-shaped material. A columnar gripping part 2 gripped by an operator is arranged on one end side of the handle part 3 of the roller handle 1. The handle part 3 is gripped by the gripping part 2 and one end thereof is gripped by one end part of the gripping part 2. It is fixed by embedding following the central axis of the part 2.

  The handle portion 3 has a leg portion 31 that extends from the grip portion 2 onto the center axis of the grip portion 2, and communicates with the leg portion 31. A body part 32 bent so as to form a letter-shape, and a body part 32 that communicates with the body part 32 and is bent so as to be parallel to the central axis of the grip part 2, and rotates the head part 4 described later. A neck portion 33 for freely supporting is provided, and the tip of the neck portion 33 is bent 90 ° inside, that is, above the center axis of the grip portion 2 to form a pivot shaft portion 33a. The central axis of the rotation shaft portion 33a functions as a rotation shaft of the head portion 4 described later. The body 32 and the neck 33 are bent in the same plane.

  In the present embodiment, the case where the inclined body portion 32 is provided has been described. However, the present invention is not limited to this, and the body portion 32 is a position that is appropriately separated from the grip portion 2 of the handle portion 3. It may be configured to be bent into an appropriate shape such as a crank shape or an arc shape, or may be configured linearly without bending between the leg portion 31 and the neck portion 33 at an intermediate position.

  A head portion 4 for attaching a roller (not shown) is rotatably supported on the rotation shaft portion 33a. The head portion 4 has rod-like support arms 41 and 41 that support rollers at both ends of a short rod-like base arm 42 that is rotatably supported by a rotation shaft portion 33a. A cylindrical bearing portion 43 through which the pivot shaft portion 33a is inserted is provided at the center position in the longitudinal direction of the base arm 42.

  On the other hand, the outer diameter of the tip end portion of the rotation shaft portion 33a is made smaller than the outer diameter of the other portions to form a stepped portion. The aforementioned inner diameter of the bearing portion 43 is larger than the outer diameter of the tip end portion of the rotation shaft portion 33a and smaller than the outer diameter of the portion other than the tip end portion of the rotation shaft portion 33a. Then, by passing through the bearing portion 43 and screwing the nut 45 into the tip end portion of the rotation shaft portion 33a protruding from the bearing portion 43, the head portion 4 can be rotated around the rotation shaft portion 33a. It is supported. Here, the rotating shaft portion 33a and the support arms 41, 41 of the head portion 4 are parallel to each other.

  Thereby, in a state where the head part 4 is separated from the area to be coated, the head part 4 can be rotated around the rotation shaft part 33a, while the head part 4 is in contact with the area to be coated. Then, the grip part 2 can be swung around the rotation shaft part 33a.

  Here, the length dimension of the base arm 42 of the head portion 4 described above, that is, the dimension between the support arms 41, 41 is such that when the cylindrical rollers are respectively attached to the support arms 41, 41, the two rollers are mutually connected. It is set not to touch. Further, the dimensions of the neck portion 33 and the inclination angle of the body portion 32 are such that the head portion 4 is rotated around the rotation shaft portion 33a with the cylindrical rollers attached to the support arms 41, 41 of the head portion 4, respectively. At this time, both rollers are set so as not to contact the body portion 32.

  In the roller handle 1 shown in FIGS. 1 to 3, the head portion 4 is provided with the bearing portion 43, and the neck portion 33 is provided with the rotation shaft portion 33a. However, the present invention is not limited thereto, Needless to say, the shaft portion for rotation may be provided in the head portion 4 and the bearing portion may be provided in the neck portion 33.

  By the way, a plurality of claw portions 21, 21, 21, 21 (four in FIG. 1 to FIG. 3) extend in parallel with the central axis of the grip portion 2 on the peripheral edge on one end side of the grip portion 2 described above. For example, the roller attached to the head portion 4 of the roller handle 1 is not brought into contact with the floor or the ground by hooking an appropriate claw portion 21 to the edge of an empty container. The handle 1 and the roller can be held.

Next, how the roller handle is used will be described.
4A and 4B are explanatory views for explaining a state in which a wall is painted using the roller handle according to the present invention. FIG. 4A shows a case where a relatively high area is painted, and FIG. 4B shows a floor. This shows the case where the lower region close to is painted. In FIG. 4, parts corresponding to those shown in FIGS. 1 to 3 are denoted by the same reference numerals.

  When the wall W is painted using the roller handle 1, the support arm constituting the head portion 4 of the roller handle 1 enters from the center of the ends of the cylindrical rollers R and R along the respective central axes. As a result, after the rollers R and R are attached to the head portion 4, the rollers R and R are sufficiently impregnated with paint as described later.

  Then, as shown in FIG. 4A, when painting a relatively high position of the wall W, the operator grips the grip portion 2 to bring the rollers R and R into contact with the wall W, and this state Then, the wall W is painted by moving the rollers R and R in the vertical direction. At this time, since the grip portion 2 swings around the pivot shaft portion between a posture substantially parallel to the floor F and a posture inclined to the floor F side, it can be smoothly painted even in a relatively high region. Work can be done.

  Further, as shown in FIG. 4B, when the lower region close to the floor F is painted, the grip portion 2 is substantially parallel to the floor F continuously from the aforementioned swing region around the pivot shaft portion. Since the swinging motion is performed between the vertical posture and the posture inclined to the opposite side of the floor F, the operator can continuously move the rollers R and R to the lower region without changing the grip portion 2. The region can be painted by moving the rollers R and R in the region in the vertical direction. When the paint in the rollers R and R is reduced during the painting operation, the operator impregnates the rollers R and R with the paint as follows.

  FIG. 5 is an explanatory view for explaining a method of impregnating a roller attached to a roller handle according to the present invention with a paint. In the figure, the same reference numerals are given to the portions corresponding to the portions shown in FIG.

  As shown in FIG. 5, the paint is stored in a container C having an open top. The operator grasps the grip portion 2 and visually checks whether one of the rollers R and R attached to the head portion 4 of the roller handle 1 is positioned at the tip, and the rollers R and R are both at the tip. If it is positioned, for example, by rolling the rollers R and R to the inner wall of the container C, one of the rollers R is positioned at the tip. In this state, the operator impregnates the roller R with the paint by immersing the roller R at the tip in the paint in the container C.

  When the roller R is immersed in the paint for an appropriate period of time and the roller R is sufficiently impregnated with the paint, the operator pulls the roller R out of the paint and drops excess paint from the roller R to remove it.

  Next, the operator who grips the grip portion 2 collides the roller R with the inner wall of the container C, for example, and rotates the head portion 4 around the rotation shaft portion 33a to position the other roller R at the tip. Let Then, after performing the same operation as before, the other roller R is sufficiently impregnated with the paint, and then the roller R is pulled out from the paint, and excess paint is dropped and removed from the roller R.

  In such a roller handle 1, since the portion immersed in the paint can be limited to the portions of the rollers R and R, the waste of the paint can be reduced as much as possible. Similarly, since the portion immersed in the paint can be limited to the portions of the rollers R and R, the time required to remove the extra paint can be shortened as much as possible. , R can maintain high working efficiency.

  On the other hand, since any roller R of the two rollers R, R can be positioned at the tip without changing the grip portion 2, both rollers R can be positioned at an appropriate timing by replacing both rollers R at appropriate timing. The consumption rate of the rollers R and R can be managed to the same extent, and the service life of both the rollers R and R can be extended.
