DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the principle of coating with a coating attachment according to the present invention. In the figure,
Reference numeral 10 denotes a mounting holder which is detachably attached to a spray gun or a spray can. And a pair of light-emitting units including a laser light-emitting device and the like attached via the light-emitting device.

The respective optical axes R1 and R2 emitted from the light emitting sections 20A and 20B intersect at the coating surface 1 of the object to be coated which is located in front of the spray axis direction L of the spray gun or the spray can. The intersection X can be appropriately adjusted as described above, and there is a case where the intersection X itself may be difficult to see due to the spray paint, depending on the paint used, or as a paint aiming point of a spray gun or a spray can. The range is designated as a paint aiming area (an area in a certain range slightly apart from the paint aiming point vertically or horizontally).

Therefore, if the user (operator) sprays paint from a spray gun or a spray can using this as a guide (mark) while maintaining the intersection X of the light emitting sections 20A and 20B, the user always has a constant value. Can be maintained, and a substantially uniform coating can be obtained.

In setting the intersection X of the optical axis lines R1 and R2, the optimum separation distance (coating distance) between the spray gun and the spray can differs depending on the model, but for the spray gun, it is about 150 to 200 mm. Since the spray can is approximately 150 to 300 mm, the distance between the spray nozzle (not shown) and the painted surface 1 is measured in advance using a measure (ruler) 2 or the like, and based on this separation distance, the optical axes R1 and R2 are measured. What is necessary is just to set so that the intersection X can be obtained.

To change the intersection distance between the optical axes R1 and R2, for example, the light emitting units 20A and 20A
The light-emitting unit holder pieces 21 and 21 for holding B are attached with fasteners 22 and 22 such as screws, and when changing them, the fasteners 22 and 22 are loosened and the orientation in the horizontal direction is appropriately changed. You only have to stop it again and it's easy.

Further, as described above, the optical axes R1, R2
If there is a risk that the intersection X itself may be difficult to see due to the spray paint, the intersection X may be slightly displaced from the spray axis direction L of the spray gun or the spray can, so that it becomes easier to see. The arm 30 may be attached to the holder 10 so that the arm 30 can be adjusted upward or downward. As this adjustable mounting method, for example, the base ends of the pair of arm pieces 31, 31 are fixed with fixtures 32 such as bolts 32a and nuts 32b,
At the time of the adjustment, the fixture 32 may be loosened, the up / down direction may be changed as appropriate, and then firmly stopped again.

The mechanism for adjusting the up and down direction is provided by the light emitting unit holder pieces 21 and 21 of the light emitting units 20A and 20B.
A mechanism for changing the intersection distance between the optical axes R1 and R2 may also be incorporated into the mounting mechanism between the pair of arm pieces 31 and 31 and the mounting holder 10.

FIGS. 2 to 4 show a case in which the coating attachment according to the present invention is applied to a spray gun. In this case, the mounting holder 10 comprises a substantially C-shaped frame body 110, A part of the spray gun 200, for example, is fitted to the base end side of the spray nozzle 210, and is fixed by a fixing tool 111 such as a screw. Reference numeral 220 denotes a grip of the spray gun 200, reference numeral 221 denotes a firing trigger, and reference numeral 230 denotes a paint cup.

In this coating attachment, the light emitting section 2
A small battery is used as the power supply 40 for the terminals 0A and 20B, and is mounted on, for example, the bottom surface of the arm piece 31. It has become. Of course, the light emitting units 20A and 20B and the power supply 4
A predetermined wiring (not shown) is provided between 0 and the blinking switch 50.

Therefore, when using the spray gun 200, as described above, the light emitting units 20A, 2A
The respective optical axis lines R1 and R2 irradiated from 0B are appropriately adjusted so as to intersect with the coating surface 1 of the object to be coated, and while maintaining this intersection X, this is set as a coating aiming point or as a coating aiming area. What is necessary is just to spray paint.

If the spray gun 200 approaches or moves away from the predetermined separation distance during this coating, the intersection X of the optical axes R1 and R2 shifts and is displayed as two light-emitting points. Accordingly, the distance between the two points increases, so that the user (operator) can visually and immediately know whether or not the holding state is appropriate.

For this reason, if the user (operator) immediately returns the holding state of the spray gun 200 so that the intersection X of the optical axes R1 and R2 is clearly imaged before a large displacement occurs, an appropriate state can be obtained. A separation distance is realized, and extremely good usability is obtained.

FIGS. 5 to 7 show the case where the coating attachment according to the present invention is applied to a spray can.
In this case, the mounting holder 10 is composed of a substantially L-shaped angle member 120, and the angle member 120 has two belt pieces 121, 121 and these belt pieces 1
A fixture 130 having a gear mechanism and the like for fixing the components 21 and 121 is attached. That is, the two belt pieces 121, 1 turned around the outer periphery of the spray can 300.
Both free ends 21 are fixed by fixtures 130. Reference numeral 310 denotes a spray nozzle of the spray can 300.

In this coating attachment, the light emitting section 2
A small battery is also used as the power supply 40 for the 0A and 20B, and is mounted on, for example, the bottom surface of the arm piece 31 and is flashed by the flashing switch 50 for the light emitting unit also mounted on the arm piece 31. It has become. Of course, the light emitting units 20A and 20B and the power supply 4
A predetermined wiring (not shown) is provided between 0 and the blinking switch 50.

Therefore, when using the spray can 300, as described above, the light emitting units 20A and 20A are used.
The respective optical axes R1 and R2 emitted from B are appropriately adjusted so as to intersect with the coating surface 1 of the object to be coated, and while maintaining this intersection X, this is set as a coating aiming point or as a coating aiming area. What is necessary is just to spray paint.

If the spray can 300 approaches or moves away from the predetermined separation distance during the coating, the intersection X of the optical axes R1 and R2 is also displaced and displayed as two light-emitting points. Depending on this 2
Since the distance between the points is increased, the user (operator) can instantly visually recognize the suitability of the holding state.

For this reason, if the user (operator) immediately returns the holding state of the spray can 300 so that the intersection X of the optical axes R1 and R2 is clearly imaged before a large displacement occurs, an appropriate state can be obtained. A separation distance is realized, and extremely good usability is obtained.

In the above embodiment, a small battery is used as the power source 40 in consideration of portability, but the present invention is not limited to this, and the power source can be supplied by a power cord. The shape of the mounting holder 10 is also substantially C-shaped frame 11.
The angle is not limited to 0 or a substantially L-shaped angle member 120, and can be appropriately changed according to the shape of the spray gun 200 or the spray can 300.

[0030]

As is clear from the above description, the coating attachment according to the present invention has the following excellent effects.

(1) First, as a most significant feature, since the intersection of the respective optical axes emitted from the pair of light emitting portions indicates the optimum distance for painting, the user maintains this intersection. Using this as a guide (painting aiming point and painting aiming area), the paint can be sprayed from a spray gun or spray can in accordance with these instructions. It can be performed.

(2) If the spray gun or spray can approaches or moves away from the predetermined distance (coating distance) during coating, the intersection of the two optical axes shifts.
The point is displayed as a light-emitting point, and the distance between the two points increases in accordance with the degree of the shift, so that there is an advantage that the user can visually and immediately know whether or not the holding state is appropriate. Therefore, also before a large deviation, the user should change the holding state of the spray gun and spray can,
What is necessary is just to return immediately so that the intersection of the two optical axes forms a clear image, it is easy to deal with the deviation, and extremely good usability is obtained.

(3) Further, there is an advantage that the coating attachment itself is small and can be easily attached to a spray gun or a spray can.

(4) Further, if the arm is mounted on the mounting holder so that the arm can be adjusted upward or downward, or the light emitting section is rotatably mounted on the free end side of the arm via a light emitting section holder piece, the coating distance can be increased. Adjustment and upward and downward adjustment of the intersection of both optical axes can be performed easily and easily.
Also in this respect, good usability is obtained.

(5) If a laser light emitting device is used as the light emitting portion, the device is small and excellent in portability. For example, in the case of a red laser light emitting device, a converged and clear optical axis can be obtained, so that the intersection is clearly formed. It is visible and good workability is obtained.

(6) If a battery is used as a power source,
A coating attachment with excellent portability can be obtained.
