' Maw EXTENSION HAND SPRAYER DEVICE BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to hand actuated spray can extension sprayers for spraying a guide mark on the pavement.
SUMMARY OF THE INVENTION The present invention includes a spring clip holder for a paint spray can having a push button spray head mounted thereon. An extension arm is secured to the can support and extends to a handle some distance from the can support. The push button arrangement is fastened to the arm adjacent to the handle and extends to anactuator on the can support which is adapted to press against the spray head of the can to spray paint from the can.
The primary object of the invention is to provide an extension operator for a spray can to permit a guide mark to be sprayed on pavement while the operator remains in an upright position.
Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevation of the invention;
FIG. 2 is a top plan view of the invention; and
FIG. 3 is an enlarged transverse cross-section taken on the line 3-3 of FIG. 1 looking in the direction of the arrows.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures the reference numeral indicates generally an extension hand sprayer constructed in accordance with the invention.
The extension hand spray 10 includes an elongate arm 11 having a handle 12 secured to one end thereof. A can support bar 13 is integrally secured to the end of the arm 11 opposite the handle 12 and extends downwardly therefrom.
' A pair of spring clamps l4, 15 are secured to the bar 13 in spaced parallel relation and are adapted to receive a spray paint can 16 clamped therein as can be seen in FIG. 1. An actuator 17 is rigidly secured to the bar 13 adjacent the arm 11 and has an upstanding end portion 18 integrally formed thereon. The actuator 17 is adapted to engage against the push bottom 19 of the spray can 16 and is flexible to permit it to be flexed downwardly to depress the push button 19 to spray paint from the can 16. An elongate rod 20 is mounted on the arm 11 in a plurality of guides 21 to permit the rod 11 to have longitudinal sliding movement therein. The rod 11 extends through the upright portion 18 of the actuator 17 and is secured thereto by welding 22.
A thumb button 23 is secured to the opposite end of the rod 20 immediately above the handle 12 in a position to be pressed by the thumb of the user when desired.
In the use and operation of the invention when laying out a line in a road a chalk line is first stretched over the area to be marked and then someone walks along the entire length of the line with a conventional spray can of aluminum bright colored paint following which the chalk line is removed leaving a painted line on the surface for a machine to follow. In the use of the present invention a similar system is followed except that the user presses the thumb button 23 to depress the push button 19 of the spray can 16 and with arm 11 is enabled to spray the surface of the road along the chalk line while remaining erect rather than having to stoop over and spraying directly from a spray can.
When the spray can 16 is emptied it may be slipped from the spring clips l4, l5 and a new spray can inserted to continue the spraying operation.
Having thus described the preferred embodiment of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.
1. An extension hand spraying device comprising an elongate arm, a handle integrally secured to one end of said arm, a bar integrally depending from the other end of said arm, a pair of spaced parallel spring clips mounted on said bar for supporting a can thereon, a flexible actuator having one end thereof rigidly secured to the upper end of said bar for engaging against the spray nozzle of a paint can supported by said spring clips, and means extending completely along said arm for flexing said actuator in a direction toward the spray nozzle of a can supported in said can support with said last named means including a rod, a plurality of guides secured to said arm with said rod mounted for longitudinal movement therein, welding means securing one end of said rod to the other end of said actuator, and a thumb button rigidly secured to the opposite end of said rod adjacent said handle.
