EXTENSION HAND SPRAYER DEVICE
Abstract
An extension hand sprayer device for spraying a line on the
pavement while standing erect which includes a spray can holder, an
extension arm secured thereto and extending a substantial distance
therefrom terminating in a handle. A push button mounted for
sliding movement on the arm is connected to a member which is
adapted to press against the push button of the spray can when
actuated by thumb pressure on the push button mounted on the
arm.

Claims
I claim:
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.
Description
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 an
actuator 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 10 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 14, 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 14, 15 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.
