Description

  The present invention relates to an applicator. For example, the present invention relates to an applicator used when applying a chemical solution such as paint or wrinkle removal or other fluid.

  As disclosed in Japanese Utility Model Laid-Open No. 57-35880, Japanese Utility Model Laid-Open No. 62-202382, Japanese Utility Model Laid-Open No. 2-48175, Japanese Patent Application Laid-Open No. 2000-197849, and Japanese Patent Application Laid-Open No. 2002-143754, At the time of application, an applicator having a rotating roller that is rotatably attached to the tip of the gripping part is widely used.

By the way, in the proposed applicator, it has been proposed to provide a cover body so as to cover the rotating roller in order to prevent scattering of the paint on the rotating roller, and in particular to prevent scattering to the operator.
Japanese Utility Model Publication No. 57-35880 Japanese Utility Model Publication No. 62-202382 Japanese Utility Model Publication No. 2-48175 JP 2000-197849 A JP 2002-143754 A

Now, although the applicator as described above has been proposed, it is still only a proposal and has not been put into practical use.
It has been found that the reasons that have not been put into practical use are as follows.
For example, when the cover body that covers the rotating roller is rotatable, one end of the cover body may come into contact with the coating surface after the coating of the coating material during the application. If it does so, it will become a locus | trajectory and application | coating will not be performed favorably.
Even when the cover body is fixed, when the arm having the gripping part is applied by extending forward or retracting backward, the cover body contacts the application surface depending on the degree of bending and stretching. Accordingly, in this case as well, one end of the cover body comes into contact with the application surface after the coating of the paint so as to scratch, and this becomes a trajectory and the application is not performed well.

  In any case, with the conventional applicator, the paint cannot be applied neatly.

  Therefore, the problem to be solved by the present invention is to solve the above problems. In other words, it is possible to effectively prevent chemicals such as paint from splashing on the operator, but the applicator can be applied neatly without scratching the application surface by the cover body provided to prevent scattering. Is to provide.

Now, in order to effectively prevent the chemical solution attached to the rotating roller from scattering to the operator, a cover body that covers the rotating roller will be necessary.
Therefore, it is a problem how to devise the cover body.

  While diligently pursuing the study on this problem, I realized that the problem with the applicator so far occurred because the cover body was in contact with the application surface. That is, although it is very simple, even if the cover body comes into contact with the surface before application (the surface to be applied from now on) instead of the surface after application, this does not have any problem. Therefore, it came to the revelation that the above-mentioned problem would be solved if the cover body was rotatably attached so as to contact the surface before application.

The present invention has been made based on such findings.
That is, the above problem is
A gripping portion; a rotating roller attached to the extending portion from the gripping portion; and a rotatable cover body that covers the rotating roller attached to the extending portion from the gripping portion. Applicator,
This is solved by an applicator comprising a biasing means for biasing the cover body.

  In particular, in the above applicator, the urging means is configured to ground the front end side of the cover body and to float the rear end side of the cover body when moved forward while rotating the rotating roller. It is solved by the applicator characterized by being made. Alternatively, in the applicator, the urging unit is configured to ground the rear end side of the cover body and float the front end side of the cover body when the rotating roller is moved rearward while rotating the rotating roller. It is solved by the applicator characterized by being made. Among them, in the above applicator, the urging means grounds the front end side of the cover body and floats the rear end side of the cover body when the forward roller is moved forward while rotating the rotating roller. Further, when the rotary roller is rotated and moved rearward, the rear end side of the cover body is grounded and the front end side of the cover body is floated. Solved by applicator. Alternatively, in the applicator, the urging means causes a clockwise rotational force to act on the cover body when the rotating roller rotates clockwise, and when the rotating roller rotates counterclockwise, This is solved by an applicator characterized by being configured to apply a counterclockwise turning force to the cover body.

  Various methods can be considered as the biasing means having the above-described configuration. For example, it can be configured by using a biasing means such as a spring. However, when an urging means such as a spring is used, a means for switching the urging direction is required when the rotating roller rotates forward and backward (forward and backward). This is unexpectedly complicated. Therefore, it is preferable that the urging direction is automatically switched when the rotating roller rotates forward and backward. Such a method can be easily realized by configuring as follows. That is, in the applicator, the urging means transmits the rotational force of the rotating roller to the cover body as a rotational urging force via a friction body provided between the rotating roller and the cover body. It is solved by the applicator characterized by being comprised. More specifically, this can be realized by pressing an elastic body such as rubber on the side surface of the rotating roller and fixing the elastic body to a rotatable cover body. Alternatively, an elastic body such as rubber may be attached to the side surface of the rotating roller, and this elastic body may be pressure-bonded to the constituent parts of the cover body. If comprised in this way, the frictional force which arises between a rotating roller and a cover body will act as rotation biasing force with respect to a cover body. Moreover, the urging direction is automatically switched when the rotating roller rotates forward and backward.

  Further, the present invention can be solved by the applicator characterized in that the cover body is configured such that a part of the rotating roller is not covered with the cover body.

  In addition, the above-mentioned applicator is solved by the applicator characterized in that the cover body is provided with a protruding portion that protrudes forward in a position below the rotation center position of the cover body.

  In the applicator, a roller having a rotation center at a position below the rotation center position of the cover body is provided on the cover body, and the roller front end protrudes from the cover body front end. It is solved by an applicator characterized in that it is of a certain size.

  Further, the present invention is solved by the applicator characterized in that the rotation axis of the cover body and the rotation axis of the rotation roller are on the same line.

  According to the present invention, the cover body effectively prevents the chemical solution attached to the rotating roller from being scattered. Therefore, the working environment is improved.

  And since the cover body provided to prevent chemical splashing is rotatable, the angle between the application surface and the gripping part (arm) changes according to the bending and stretching of the arm with the gripping part. However, the cover body also moves in accordance with this change in angle, and the cover body does not interfere with the application. For example, if the cover body is fixed, depending on the bending and stretching of the arm, the cover body hits the application surface before the rotating roller contacts the application surface, and the application may not be performed successfully, but the cover body can be rotated. Therefore, such a problem does not occur.

  Although the cover body can be rotated, the cover body does not hit the surface after the chemical solution is applied, that is, the cover body will not scratch the surface after the application, so that the application is good. To be done.

  The applicator of the present invention is for applying a chemical solution such as a paint or a wrinkle remover. A gripping portion; a rotating roller attached to the extending portion from the gripping portion; and a rotatable cover body covering the rotating roller attached to the extending portion from the gripping portion. Have The most significant feature of the present invention is that an urging means for regulating the posture of the cover body is provided.

  The urging means is configured to ground the front end side of the cover body and to float the rear end side of the cover body when moved forward while rotating the rotating roller. Alternatively, when the rotating roller is moved rearward while rotating, the rear end side of the cover body is grounded and the front end side of the cover body is floated. In particular, when the rotating roller is moved forward while rotating, the front end side of the cover body is grounded and the rear end side of the cover body is floated, and the rotating roller is rotated rearward. If the cover body is moved to the side, the rear end side of the cover body is grounded, and the front end side of the cover body is floated (when the rotating roller rotates in the clockwise direction, a clockwise turning force is applied to the cover body, When the rotating roller rotates counterclockwise, the cover body is configured to apply a counterclockwise turning force). For example, specifically, the rotation force of the rotation roller is transmitted to the cover body as a rotation urging force via a friction body provided between the rotation roller and the cover body.

  Further, the cover body is provided with a protruding portion that protrudes forward at a position below the rotation center position of the cover body. In particular, the cover body is provided with a roller having a rotation center at a position below the rotation center position of the cover body, and the roller has a front end protruding from the front end of the cover body. Further, the rotation axis of the cover body and the rotation axis of the rotation roller are configured to be on the same line.

This will be described in more detail below.
1 to 3 show an embodiment of an applicator according to the present invention, and FIG. 1 is a perspective view in a state where a gripping part is held (an external force other than gravity is not acting). 2 and FIG. 2 are explanatory diagrams in a state where the vertical wall is applied by traveling (advancing) upward, and FIG. 3 is an explanatory diagram in a state where the vertical wall is applied (moving backward) and applied. is there.

  In each figure, 1 is a holding part of the applicator A. That is, when applying the chemical solution (coating material or glazing agent), the applicator A is caused to travel (apply by a rotating roller, which will be described later) with the grip portion 1 in hand.

  Reference numeral 2 denotes an extension part having a predetermined shape extending from the grip part 1. For example, it has a substantially “ma” shape. Such a shape is also well known in the applicators listed in the patent literature.

  Reference numeral 3 denotes a substantially cylindrical rotating roller. The rotating roller 3 has a bearing hole along its longitudinal direction, and the tip of the extending portion 2 from the grip portion 1 is inserted into the bearing hole. Accordingly, the rotating roller 3 can freely rotate around the tip of the extending portion 2. In addition, since such a rotation structure is also well-known in the said patent document etc., detailed description is abbreviate | omitted. The rotating roller 3 is made of a material such as cloth, nonwoven fabric or sponge. Since this point is also well known, details are omitted.

  4 is a cover body. A cover surface (a portion excluding the frame portion and the left and right wall surfaces) 4a of the cover body 4 is made of a transparent or translucent resin. Of course, it may be opaque, but it is preferably made of a transparent material since the condition of the rotating roller 3 and the state of application can be observed during application. The left and right wall surfaces 4b and 4c of the cover body have, for example, a substantially semicircular shape. Accordingly, the cover surface 4a has a substantially semicircular cross section. Of course, it doesn't matter if it is slightly over half a circle. In the present embodiment, the cover body 4 has a substantially semicircular cross-sectional structure covering the periphery of the substantially cylindrical rotating roller 3 over a range of about 200 °. In addition, the preferable cover area | region of the rotating roller 3 by the cover body 4 is over the range of 180 degrees or more. And it is over the range of 300 degrees or less. This is because, if the cover area (angle) is too narrow, the effect of preventing the chemical solution from scattering is reduced, and conversely, if the cover area (angle) is too wide, the area where the chemical liquid can be applied at a time becomes narrow. Therefore, it is preferable to cover the rotating roller in the range of 180 ° to 300 °.

  In the present embodiment, a bearing portion 4 d is configured on the wall surface 4 b of the cover body 4. And the extension part 2 from the holding part 1 is inserted in the bearing part 4d of the wall surface 4b similarly to the case of the rotating roller 3. The bearing portion 4d is composed of a concave portion formed on the wall surface 4b and an elastic substantially Y-shaped member having a latching convex portion on the inner side of the tip provided on the wall surface 4b. Therefore, the bearing portion 4d can be removed from the extending portion 2. That is, it is a detachable type. Further, the shaft 5 is inserted into the bearing portion of the other wall surface 4c (the through hole formed in the wall surface 4c, which is different from the structure of the bearing portion 4d), and the tip of the inserted shaft 5 is connected to the rotating roller 3. Fits into the bearing hole. Accordingly, the cover body 4 is attached so as to be freely rotatable with the rotation axis of the rotation roller 3 as the axis.

  Reference numeral 6 denotes a rubber body fixed to the shaft 5. The side surface of the rubber body 6 is in pressure contact with a hard shaft (not shown) of the rotating roller 3. That is, since the rubber body 6 is in pressure contact with the rotating roller 3, when the rotating roller 3 rotates, the rubber body 6 also tries to rotate in the same direction by the frictional force. That is, the cover body 4 also tries to rotate as the rotating roller 3 rotates. For example, in a free situation, when the cover body 4 is rotated around the axis, the rotation roller 3 is rotated in the same manner, and when the rotation roller 3 is rotated around the axis, the cover body 4 is rotated in the same manner. To do. That is, as long as a force larger than the frictional force does not act, the rotating roller 3 and the cover body 4 rotate together. However, if a force greater than the frictional force caused by the rubber body 6 acts on the cover body 4, the cover body 4 does not rotate but the rotating roller 3 can rotate.

  A roller 7 a is attached to the front frame portion of the cover body 4. Reference numeral 7 b denotes a roller attached to the rear frame portion of the cover body 4. Note that the rotational axis positions of the rollers 7a and 7b are lower than the rotational axis position of the cover body 4 (axial position of the shaft 5) when the gripper 1 of the applicator A is held in the hand as shown in FIG. It is provided so that it may be located in. Accordingly, when the roller 7a is pressed against the vertical wall in the state as shown in FIG. 1, a force for rotating the cover body 4 in the clockwise direction is applied to the roller 7a, and the state shown in FIG. 2 is obtained. The rollers 7a and 7b may be of a type that does not rotate, but the rotating device is superior in the operability of the applicator A.

  Now, in the state where the chemical solution is applied to the vertical wall and the rotating roller 3 is impregnated with the chemical solution and the grip portion 1 is held, as shown in FIG. 1, the cover body 4 has its own weight and the cover surface is concave. It is posture. That is, the opening surface of the cover body 4 faces upward. Therefore, even if the impregnated chemical solution is dripped from the rotating roller, it is received by the cover body 4.

  When the applicator A is brought close to the vertical wall surface in this state (the opening surface of the cover body 4 is on the upper side), first, the roller 7a hits the wall. Then, since this contact position (height) is lower than the height of the rotation axis of the cover body 4, as can be understood from the principle of action and reaction, a force that rotates the cover body 4 clockwise from the wall acts. To do. That is, the opening surface of the cover body 4 rotates from the horizontal direction to the vertical direction so that the cover body 4 covers the rotating roller 3 from behind. Therefore, it is possible to enter the coating mode without any difficulty, and even when the chemical liquid scatters from the rotating roller 3 during the application, the chemical liquid is hardly scattered to the operator because it is covered by the cover body 4.

  In this state, the arm is extended and the applicator A is moved upward. Then, the rotating roller 3 rotates in the clockwise direction. Along with this, a chemical solution is applied. At this time, since the rubber body 6 is in pressure contact with the rotating roller 3 that rotates in the clockwise direction, a force that rotates in the clockwise direction acts on the cover body 4 by the frictional force. Accordingly, as can be seen from FIG. 2, the roller 7a hits the wall surface, but the roller 7b does not hit the wall surface. That is, the roller 7a is in a grounded state, but the roller 7b is in a floating state. In other words, the front end side (upper end side) of the cover body 4 is grounded, and the rear end side (lower end side) of the cover body is in a floating state. Therefore, in this state, the cover body 4 is not touching the surface after the chemical solution is applied. What is touching is the surface before the chemical solution is applied. Therefore, the application surface is not adversely affected by the cover body 4.

  By the way, when the extended arm is bent and the applicator A is moved downward, the state shown in FIG. 3 is obtained. That is, when it is moved downward, the rotating roller 3 rotates counterclockwise. Along with this, the chemical solution is repeatedly applied and overcoated. At this time, since the rubber body 6 is in pressure contact with the rotating roller 3 that rotates counterclockwise, a force that rotates counterclockwise acts on the cover body 4 by the frictional force. Therefore, since the cover body 4 rotates counterclockwise, as can be seen from FIG. 3, the roller 7a is separated from the wall surface, and the roller 7b hits the wall surface. That is, the roller 7b is in a grounded state, but the roller 7a is in a floating state. In other words, the upper end side of the cover body 4 floats and the lower end side of the cover body is in a grounded state. In this state, the cover body 4 does not touch the surface after the chemical solution is reapplied. What is touching is the surface before the chemical solution is reapplied. Therefore, the application surface is not adversely affected by the cover body 4.

  Now, as described above, the application to the vertical surface has a great feature. For example, the same effect is exerted on the application to a horizontal ceiling surface (or floor surface). That is, scattering of the chemical solution can be prevented and it is difficult to cause an adverse effect on the coated surface. Moreover, the coating workability is also good. Furthermore, a curing (preliminary) operation such as application of the ceiling surface after a sheet is laid on the floor in advance is unnecessary, which is very simple.

  If the cover body 4 is detachable, the cover body 4 can be removed when the rotating roller is immersed in the chemical solution, which is very convenient. Of course, a structure that can move to a position away from the position of the rotary roller 3 as well as the complete removal is also possible.

FIG. 4 is an explanatory view of an applicator according to the second embodiment of the present invention.
The basic structure of the applicator B of this embodiment is the same as that of the applicator of the above embodiment.
However, the applicator A of the embodiment is such that the rotating roller 3 and the cover body 4 are rotatably mounted on the same shaft, whereas the applicator B of the present embodiment is attached to the rotating roller 3. It is different in that it is attached to a member different from the shaft.

  That is, the cover body 4 is rotatably attached to the second extending portion 11 from the grip portion 1 (extending portion 2). That is, the distal end portion 11a of the extending portion 11 can move along the guide groove portion 12 in the circumferential direction. This rotatable mounting mechanism is like a planetary mechanism as can be seen from FIG. In addition, since such an attachment mechanism is also well-known as an attachment method, detailed description is abbreviate | omitted. However, when the extending portion 2 to which the rotating roller 3 is attached and the extending portion 11 to which the cover body 4 is attached are separate members, although mechanically complicated, the rotating roller 3 is immersed in a chemical solution. It is possible to easily remove the extended portion 11 from the extended portion 2 (cancel the fitting state of both) and to prevent the cover body 4 from being immersed in the chemical solution, which is advantageous in this respect.
