DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting device for an outer wall coating device in which a plurality of manually operated outer wall coating machines are connected to perform coating in which spots of different colors are mixed.

[0002]

2. Description of the Related Art Conventionally, a plurality of high-viscosity paints mixed with different-colored aggregates are simultaneously sprayed onto an outer wall to perform coating in which spots of different colors are mixed with each other. A multi-headed outer wall painter equipped with a paint tank provided with a partition corresponding to a nozzle at the top was used.

[0003]

However, such a multi-headed outer wall coating device is heavy in weight, has poor workability, and requires a plurality of coating devices having different numbers of nozzles to spray a desired number of coating materials. Alternatively, there is a problem that it is necessary to use a large-sized coating device having an extra nozzle that is not used.

[0004]

According to the present invention, a single nozzle is provided below a paint tank provided with a grip on the rear side, for jetting paint flowing down from the paint tank forward by pressurized air. And a connecting device for an outer wall painter that connects and arranges a plurality of outer wall painters in which a lever for operating an opening / closing valve provided at the bottom of the paint tank is mounted above the paint tank. A connecting device for an outer wall painter consisting of a band that connects tanks and a connecting rod that connects levers. An arbitrary number of outer wall painters can be obtained by connecting paint tanks of commercially available outer wall painters with a band. Can be connected side by side, and the levers of one or two outer wall painters can be operated by connecting the connected outer wall painter levers with connecting rods It is possible to control the spraying of paint from all exterior wall painters at the same time, it is extremely lightweight and easy to operate, and it can be assembled at low cost using a commercially available exterior wall painter with one nozzle. effective.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1 and FIG. 2, reference numeral 1 denotes a commercially available outer wall coating device, which comprises a valve seat 4 and a valve body 5 at the lower part of a cylindrical coating tank 2 having an open top, which is conically narrowed. An on-off valve 3 is provided, and a valve body 5 is fixed to a lower end of a valve stem 10 connected to a lever 8 supported by a shaft 7 on a bracket 6 erected on the upper surface of the paint tank 2. By pushing the rear end of the lever 8 with the thumb b of the hand a holding the cylindrical grip 11 attached to the rear surface of FIG.
As shown by a solid line, the valve element 5 is lifted to open the on-off valve 3, and when the thumb b is released, the valve element 5 is moved forward together with the lever 8 by the elastic force of the coil spring 12 housed in the grip 11.
As a result, the on-off valve 3 comes into contact with the valve seat 4 and closes.
Is opened, pressurized air is blown out from the pressurized air supply pipe 14, and the nozzle 13 is mounted so that the paint flowing down by opening the on-off valve 3 is blown out from the blowout port 16 together with the pressurized air.

FIG. 3 shows two front and rear bands 19, 1 for tightening and connecting the paint tanks 2 of two adjacent outer wall painters 1.
7, the two bands 19 and 17 each have two substantially semi-circular portions corresponding to the two paint tanks 2 and fastening portions at both ends and a center.
0 is formed, and a nut 18 is fixed to the rear surface of each through hole 20 of the band 17 on the rear side.

FIG. 1 shows a three-band structure using two sets of bands 19 and 17.
This shows a state in which the outer wall coating devices 1 are integrally connected, and the paint tank 2 is tightened and integrally connected by screwing a bolt 21 passed through a through hole 20 into a nut 18.

A connecting rod 22 is penetrated closer to the manual operation part than the shaft 7 of the lever 8 and cannot be pulled out by nuts 23 screwed to both ends.

[0010] The triple-type coating device having the above-described configuration stores three types of paints mixed with aggregates of different colors in each paint tank 2, and when the cock 15 is opened, pressurized air is supplied from the pressurized air supply pipe 14. Squirts.

Then, grips 1 of the outer wall coating device 1 at both ends.
When gripping 1 with hand a and pressing the rear end of lever 8 with thumb a,
The valve elements 5 of the three paint tanks 2 are lifted to open and close the on-off valves 3.
When the thumb b is released from the lever 8, the paint that has flowed down and the pressurized air simultaneously blows out three types of paint from the ejection port 16 of the nozzle 13 to form a spot pattern. As shown by the dashed line in FIG. 2, the valve body 5 is lowered together with the lever 8 to close the on-off valves of the three outer wall coating devices 1 and the ejection of the paint is stopped by the elastic expansion force of the coil spring 12.

In the above embodiment, three outer wall coating units 1 are connected, but two or more outer wall coating units 1 may be connected.
