  Hereinafter, the operational effects of the paint splash preventing device 1 will be described while explaining the method of using the paint splash preventing device 1 according to the above-described embodiment. In the case of painting a roof (not shown) using the paint scatter preventive tool 1, first, the paint scatter preventive tool 1 is placed on the ridge side most on the roof. Then, as shown in FIG. 3, the front side of the second sheet body 4 is raised to the minimum necessary level, and as shown in FIG. 4, the spray gun G is gripped by hand, and from any of the three openings, The trigger T formed on the spray gun G is operated while being inserted into the paint splash preventing device 1 and maintaining an appropriate distance from the surface of the roof R. By the operation of the trigger T, the paint P is sprayed from the tip of the spray gun G in a spray form from the paint tank (not shown) connected to the spray gun G via the hose H. Adhere to the surface. Even when such a painting operation is under a strong wind, the paint scattering prevention device 1 is kept in a windless state, so that the paint P sprayed from the spray gun G is scattered by the strong wind, and the efficiency is increased. It is possible to prevent a situation where the roof R cannot be adhered well, and to effectively prevent the scattered paint P from being hardened in the air and becoming dust and floating in the vicinity.

  In particular, the paint scattering prevention device 1 according to this embodiment has a structure in which the second sheet body 4 is raised as described above in the painting operation, and the portion that is opened during the operation is the minimum necessary. The lower front pipe 19, the lower rear pipe 20, the lower left pipe 21, and the lower right pipe 22 are blocked by the first to fourth skirt members 9 ... 12 while remaining within the limit range. In addition, it is possible to effectively prevent the risk that the outside air passes through the inside of the paint scattering prevention device 1.

  Then, when the painting operation is completed from the ridge side to the eaves side according to the above-described procedure, the paint scattering prevention tool 1 is moved to a site (front side) where the paint is not applied and moved again to the ridge side. At this time, in the paint scattering preventive tool 1, the first to fourth wheels 5... 8 can be easily moved on the roof R. In many cases, a step is formed. When such a movement operation is performed, the step may collide with the first to fourth skirt members 9 ... 12 arranged between the first to fourth wheels 5 ... 8. Since the first to fourth skirt members 9... 12 arranged in the paint scattering prevention tool 1 are respectively formed with slits 9a. Can be resolved.

  In the paint scattering preventing device 1 according to this embodiment, the frame 2 is entirely constituted by a hollow body such as a pipe, and the first and second sheet bodies 3 and 4 are also sheets. The whole can be reduced in weight, and the moving work from the ground to the roof and the moving work from the roof to the ground become extremely easy. Further, the first and second sheet bodies 3 and 4 are made of a frame. Since it is detachable from the frame 2 and the frame 2 can be disassembled into members, it can be made compact when not in use and can be stored without being bulky.

  Further, in the above embodiment, the upper frame 14 includes the left short pipe 38, the right short pipe 39, the upper left pipe 30, and the upper right pipe 31 between the intermediate pipe 37 and the upper front pipe 28. Since three openings (reference numerals are omitted) are formed, the operator positions the arm using the left short pipe 38, the right short pipe 39 or the upper left pipe 30 during the painting work. Since a part of the body weight can be applied, the workability can be further improved.

  In the paint scattering prevention device 1 according to the above embodiment, the intermediate pipe 37, the left short pipe 38, the right short pipe 39, and the like are constituent elements. However, the present invention does not necessarily need to be a constituent element. Further, regarding the material of the frame 2, for example, metal, wood, or the like may be used as a material other than resin, and further, it is not necessary to use a pipe-shaped member.
