Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial application) This invention is used to apply paint to asphalt, cement, etc. roads and floors in parking lots, factories, warehouses, tennis courts, playgrounds, etc. This relates to a line drawer used when drawing a line.

(Prior art) Conventionally, this type of line puller has a simple long outflow port bored in the left and right width direction in the bottom plate of a floating box attached to the upper rear end of the frame. The opening/closing lid, which is formed into a simple flat plate shape, is attached with a stopper so that the amount of paint flowing out can be freely adjusted. Lines were drawn by applying paint to the road and floor surfaces using sponge pads installed between the roads.

(Problem that the invention aims to solve) However, since the bottom plate of the floating box was simply formed with a long outflow port drilled in the left and right width direction and opened and closed with a flat plate-shaped opening/closing lid, the paint was Because the paint was concentrated in the center of the outflow port of the floating box, and because the paint inside the hood that flowed out from the outflow port of the floating box was applied with a sponge pad, it was not possible to evenly level the paint, resulting in uneven coating. Because of this, it was not possible to easily and neatly draw a line on the road surface, floor surface, etc. In addition, since the width of the outlet of the floating box was the same from one end to the other,
When drawing a line on a sloped road or floor surface in a direction perpendicular to the slope, the paint flows out to the lower side of the slope, resulting in significant unevenness of paint application and It was impossible to draw lines on sloped roads or floors.

Therefore, this idea was devised to solve the problems mentioned above, and it not only makes it possible to draw lines easily and neatly on roads and floors, but also makes it possible to draw lines easily and neatly on sloping roads and floors. To provide a line drawing device that enables the drawing of lines such as the above, and also allows the line to be drawn accurately from the start.

(Means for solving the problem) In order to solve the conventional problem, this invention has a paint outlet in the bottom plate of a floating box for temporary paint storage, which is attached to the upper part of the rear end of the frame. A fitting part having an appropriate length in the left and right width direction is provided, and in this fitting part, an appropriate number of rectangular outflow holes for drawing a line on a horizontal plane divided at appropriate intervals in the longitudinal direction are provided on the adjustment plate, and an appropriate number of rectangular outflow holes with a width A paint flow rate adjusting body is provided with a slit-shaped flow hole for drawing a line on an inclined surface that gradually becomes narrower from one end to the other end.
A roller is fitted between the two side plates in the hood, which is fitted so as to be swingable in the front and back directions via a swing lever, and is supported between the rear end sides of the both side plates of the frame body so as to be swingable. The floating box is rotatably supported so that its axis is located slightly forward from directly below the outlet of the floating box.

(Function) This invention is achieved by the technical means mentioned above.
When the swing lever is swung forward to align the outflow holes of the paint outflow rate regulator with the outflow ports of the floating box, the outflow holes of the paint outflow rate adjuster are disconnected from each other, causing the paint to float. To prevent the paint from concentrating on the central part of the outlet of the box, and to evenly level the paint inside the hood that has flowed out from the outlet of the floating box with a roller to prevent uneven coating. .
