Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a scattering prevention device for a spray painting tool that can prevent paint from scattering in any direction during spray painting.

Conventionally, when spray painting architectural structures, it was necessary to apply anti-scattering sheets over large areas, such as windows, columns, or other walls, in order to prevent the spray from spreading to areas that did not require painting. Ta.

Attaching anti-scattering sheets to the walls of high-rise buildings in the event of strong winds requires considerable skill and effort. Also, when spray painting the upper edge of a wall, another worker had to hold out a board or the like from the rooftop to prevent the spray from scattering onto objects on the rooftop or other buildings. The present invention eliminates the above-mentioned drawbacks and provides a scattering prevention device in which a scattering prevention plate is detachably attached to a spray coating tool to form a shielding plane in any direction, thereby reducing labor and improving work efficiency. be.

. Embodiments of the present invention will be described with reference to the drawings. Figure 1 shows
Wrap a band 1 made of hardwood around the circumferential surface of the body A of the spray painting tool,
An elastic material 2 is provided on the inner peripheral surface of the band 1.

(There is no need to provide the elastic material.) In the band 1, a scattering prevention plate mounting frame 4 (hereinafter referred to as the mounting frame) is provided in front of the nozzle B by a connecting arm 3 and approximately concentrically with the nozzle B. It is being The connecting arm 3 may be detachably connected to the band 1 by screwing or other methods, or may be formed integrally. If they are detachably connected, the bulk during transportation can be reduced.

Further, although the connecting arms are provided on both sides of the belt, the connecting arms may be extended from the front central part of the belt to support the mounting frame.
The mounting frame 4 has an appropriate shape such as circular, square, or octagonal.
．． It is preferable to form it into a band shape with a width of 5 cm to 3.5 cm. FIG. 2 shows that the band 1 is divided into a front part 5 and a rear part 6, each of which has both ends bent outward, and the bent parts 5a, 5a, 6a.
, 6a are made with through holes 7, 7, 7, 7, and the front part 5 and the rear part 6 are
It is attached with screws so that it can be attached and detached. 3 and 4 show that the front end 5b of the band 1 and the rear end 6b adjacent to the front end 5b are curled and connected into a hinge shape 9, and the other end 5C of the front part and the other end of the rear part are curled. 6C has hook part 1 on either side.
0, a lever 11 is provided on the other side, a connecting ring 13 is provided on the lever 11, and a detachable connecting part is formed by a crank mechanism in which the shaft support of the lever and the connecting ring exceeds a fulcrum 14 to form a dead point. This is what I did.

If the band 1 is made of a relatively thin iron plate, even if it is formed into an annular shape and a removable connection part is provided at one place, the elasticity of the iron plate will push the annular band further apart from the removable connection part. It can be wrapped around the trunk A. FIG. 5 shows a scattering prevention plate 15, which is made of a thin plate made of metal synthetic resin or the like and is formed into a rectangular shape with one end slightly narrow, and can be attached and detached with a clip 17 by abutting the narrow part 16 on the mounting frame 4. It is to be installed on.

If the mounting frame 4 is circular, the scattering prevention plate can be attached in any direction along the circumference, but in this case, the contact part of the scattering prevention plate should be curved along the mounting frame. Preferably. In the case of a polygon, it may be a flat plate as shown in the example. 6 to 8 illustrate the state in which the scattering prevention plate 15 is clipped to the mounting frame 4.

A concave locking portion 19 is provided on the scattering prevention plate 15 and the mounting frame 4,
The holding portion 18 of the clip is locked to the locking portion 19.
In the crib, a plate-shaped scattering prevention plate holder 17a is extended to one side of the holding part 18 so that the holding part 18 is engaged with the locking part 19 and at the same time comes into contact with the back surface of the scattering prevention plate 15.

That is, the holding portion 18 has a convex shape with respect to the scattering prevention plate receiver 17a. The clip 17 is not limited to the one in which the holding portions are linearly opposed as shown in FIG. 6, but may also have opposing surfaces as shown in FIG. 7.

In this case, the convex portion 21 is formed so as to be locked in the five concave portions of the locking portion 19, and the holding surface can also serve as the scattering prevention plate receiver 17a. In the present invention, as described above, the band 1 is removably wrapped around the circumferential surface of the coating material storage body of the spray paint tool, so when spraying over a wide area, the conventional spray paint tool can be used as is, and When spraying on a wall near a rooftop, the band 1 may be wrapped around it and the scattering prevention plate may be clipped to the mounting frame in an appropriate direction as necessary. The scattering prevention plate has a flat plate shape and can be attached to an appropriate position along the circumferential surface of the mounting frame, so that a flat shielding surface can be formed in any direction.

For example, when spraying on a wall near the rooftop, if the scattering prevention plate 15 attached above the mounting frame 4 is moved laterally while making contact with the upper edge of the wall, the air will be sprayed above the upper edge of the wall. A sprayed surface that does not scatter and is in a straight line along the upper edge can be obtained. Therefore, since there is no scattering to objects placed on the roof, there is no need for other workers to hold out boards or the like to prevent scattering as in the past, and there is no need for extensive scattering prevention sheets, significantly improving work efficiency. can be increased.
In addition, since a planar shielding surface can be formed in any direction,
Not only on the upper edge of a wall surface as described above, but also when forming a color-coded spraying surface on a flat surface, a straight and clear boundary line of the spraying area can be easily obtained by mixing the pigment.

Furthermore, the shatterproof plate 15 can be easily attached and detached with a clip, and the clip is provided with a shatterproof plate holder 17a, so that the clamping part 18 of the clip can be held between the mounting frame 4 and the shatterproof plate 1.
Since the anti-scattering plate 15 is formed to be locked to both of the locking parts of the clip 5, the anti-scattering plate 15 maintains the fixed position attached to the mounting frame 4 together with the clip, and even against the injection pressure applied to the tip of the anti-scattering plate. It will not shift or fall off even under the weight of the coating material attached.

Since the above-mentioned scattering prevention plate can be easily attached and removed using clips, it can be replaced with a new scattering prevention plate even during work, and all that is required is to remove the adhered coating material and wash it after the work is completed.
(Note that the type of clip is not limited.) According to the present invention,
As described above, the shielding plane can be easily formed at any time and in any direction, resulting in a significant improvement in work efficiency.
