Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a wire drawing device for ground coats and the like using a commercially available aerosol type paint.

(Prior Art) Conventionally, this type of wire drawing machine is equipped with, for example, a trolley and a hand handle, and a can containing an aerosol type paint is attached in the opposite direction to the hand handle, and the nozzle is manually opened and closed. A structure in which the push handle is operated independently and independently is known from Japanese Patent Application Laid-Open No. 58-3665.

(Problem to be solved by the invention) However, this structure is inconvenient in use because it requires double work to spray paint from the can by opening and closing the nozzle, which is unrelated to operating the hand handle. I was at fault.

(Means for solving the problem) The present invention has a through hole in the bottom that extends downward through the nozzle and is large enough to be loaded with an aerosol type paint can that is ejected when the nozzle is pushed in. The hand handle is equipped with a dolly provided with a bottomed cylindrical part, and a hand handle attached to the dolly that can be raised and lowered freely, and the hand handle is tilted backward at an intermediate height. An attempt is made to solve this problem by providing a wire drawing machine that is equipped with a push-down beam that sprays paint by pressing against the tail end of a paint-filled can loaded in a bottomed cylindrical part. be.

〔Example〕

The embodiment shown in the figure comprises a trolley 4 having wheels 1, 1', 2, 2' on both front and rear sides and a lifting handle 3 which can be raised and lowered on the upper surface.
A bottomed cylindrical part 6 is provided on the rear half of the chassis 5, into which a can containing an aerosol type paint that is ejected when a commercially available nozzle is pushed in can be loaded in a reverse direction and exchangeably. A through hole 7 is formed in the wall through which the nozzle ′ of the paint can pierces downward, and a flange ″ provided on the outer periphery of the nozzle ′ is engaged with the incisal edge of the through hole 7. At the same time, a round hole 8 having a diameter slightly larger than the thickness of the paint can is formed in the front half of the chassis 5, and a bottom plate 9 is placed below the first half to hold a spare paint can. Spare storage 10,1 loaded with
0', and at an intermediate height of the hand push handle 3, the push handle 3 is in pressure contact with the tail end surface of the paint-filled can loaded in the bottomed cylindrical portion 6 when the hand push handle 3 is tilted backward. A push-down beam 11 is provided, and a hanging wall 1 is provided at the center of the rear edge of the bottom plate 9.
2, a vertical elongated hole 13 is formed in the hanging wall 12, and a U-shaped frame 1 is inserted in the rear edge of the chassis 5 in a backwardly extending state.
4, a U-shaped hanging member 15 is provided on the frame portion 14 so as to be able to swing freely in the front and back direction, and separately, a U-shaped wide member 16 for baseball with an inner diameter of 76.2 mm and a U-shaped wide member 16 with an inner diameter of 76.2 mm are provided. A width determining body 18 is constructed by combining a 50 mm U-shaped narrow member 17 for general sports with their center lines aligned back to back, and the sprayed paint passes through the back wall of the wide member 16 and narrow member 17. A hole 19 is opened, and a center shaft 20 made of a screw rod is provided on the front edge of the width determining body 18 in a forwardly protruding state, and a U-shaped handle 21 is provided on the rear edge thereof in a rearwardly protruding state. is arranged below the rear half of the chassis 5 so that the passage hole 19 for the ejected paint is located directly below the passage hole 7 of the nozzle 1, and the central shaft 20 is placed in the elongated hole 13 and the handle 21 is placed in the hanging member 15. A pair of nuts 22, 22' are fitted loosely into each other and are screwed onto the central shaft 20 at positions on both sides of the elongated hole 13 with a slight distance between them, thereby making it impossible to pull out the concentric shaft 20. The chassis 5 is equipped with a width determining body 18 so as to be vertically movable and vertically reversible.

(Operations and Effects of the Invention) Since the present invention has the above-mentioned configuration, after placing the entire body on the drawing surface, the hand push handle is tilted and the tail end surface of the paint can loaded into the bottomed cylindrical portion is moved. Line drawing can be performed by opening the nozzle by pressing with the push-down beam and at the same time pushing the hand handle forward in the above-mentioned tilted state.

Therefore, in accordance with the present invention, there is no need to operate the chassis using a hand-held handle and to spray paint from a can as separate operations unlike in the above-mentioned known method, and the operation is extremely simple, thereby solving the above-mentioned problem. This has the effect of being able to sufficiently resolve the points.
