Spraying apparatus

Claim 2

A spraying apparatus for spraying the contents of a valve-equipped aerosol spray can comprising elongated front and rear housings, one of the housings being telescopingly received by the other housing and the rear housing having a hand grip thereon, mounting means on the front housing for holding an aerosol spray can, a front actuator rod mounted within the front housing for longitudinal sliding movement therein, a rear actuator rod mounted within the rear housing for longitudinal sliding movement therein, the front and rear actuator rods being telescopingly related and the rear actuator rod having a finger grip thereon adjacent the hand grip of the rear housing, valve-actuating means on the front housing connected to the front actuator rod for opening the valve of the aerosol can when the front actuator rod moves longitudinally, a latch housing on one of the actuator rods and a latch positioned within the latch housing for movement in a direction transverse to the direction of said longitudinal movement, spring means for resiliently biasing the latch into a latching position, and an actuating button for the latch extending from the latch housing through a slot in one of the housings for moving the latch out of the latching position, the other actuator rod including a plurality of longitudinally spaced detents engageable with the latch when the latch is in the latching position whereby longitudinal movement of one of the actuator rods causes longitudinal movement of the other actuator rod, the actuator rods and the front and rear housings being telescopable when the latch is not in its latching position whereby the length of the spraying apparatus can be varied, and friction means positioned between the housings for frictionally preventing telescoping movement of the housings when the latch is in the latching position and the actuator rods are moved to open the valve but permitting telescoping movement of the housings when the latch is released.

Claim 3

The apparatus of claim 1 in which the friction means is an O-ring.

Claim 4

A spraying apparatus for spraying the contents of a valve-equipped aerosol spray can comprising an elongated tubular front housing, mounting means on the front housing for holding an aerosol spray can, an elongated tubular rear housing telescopingly received by the front housing, the rear housing having a handle at the rear end thereof, each of the front and rear housings being formed from a pair of molded plastic halves which are connected together along the longitudinal center line of the housings, an elongated front actuator rod mounted within the front housing for longitudinal sliding movement therein, crank means mounted on the front housing and connected to the front actuator rod for opening the valve when the first actuator rod is moved longitudinally, an elongated tubular rear actuator rod mounted within the rear housing for longitudinal sliding movement therein, the front actuator rod being telescopingly received by the rear actuator rod, the rear end of the rear actuator rod terminating adjacent the handle of the rear housing, the front actuator rod including a plurality of longitudinally spaced detents, a latch housing mounted on the forward end of the rear actuator rod, a latch positioned within the latch housing for movement in a direction transverse to the direction of said longitudinal sliding movement, the latch being movable within the latch housing between a latching position in which the latch is engageable with said detents on the front actuator rod and the front and rear actuator rods are secured against telescoping movement and a released position in which the latch is not engageable with said detents and the actuator rods and the front and rear housings are telescopeable to vary the length of the spraying apparatus, and friction means positioned between the housings for frictionally preventing telescoping movement of the housings when the latch is in the latching position and the actuator rods are moved to open the valve but permitting telescoping movement of the housings when the latch is released.

Claim 5

A spraying apparatus for spraying the contents of a valve-equipped aerosol spray can comprising an elongated tubular front housing, mounting means on the front housing for holding an aerosol spray can, an elongated tubular rear housing telescopingly received by the front housing, the rear housing having a handle at the rear end thereof, each of the front and rear housings being formed from a pair of molded plastic halves which are connected together along the longitudinal center line of the housings, an elongated front actuator rod mounted within the front housing for longitudinal sliding movement therein, crank means mounted on the front housing and connected to the front actuator rod for opening the valve when the first actuator rod is moved longitudinally, an elongated tubular rear actuator rod mounted within the rear housing for longitudinal sliding movement therein, the front actuator rod being telescopingly received by the rear actuator rod, the rear end of the rear actuator rod terminating adjacent the handle of the rear housing, the front actuator rod including a plurality of longitudinally spaced detents, a latch housing mounted on the forward end of the rear actuator rod, a latch positioned within the latch housing for movement in a direction transverse to the direction of said longitudinal sliding movement, the latch being movable within the latch housing between a latching position in which the latch is engageable with said detents on the front actuator rod and the front and rear actuator rods are secured against telescoping movement and a released position in which the latch is not engageable with said detents and the actuator rods and the front and rear housings are telescopeable to vary the length of the spraying apparatus, and friction means positioned between the housings for frictionally preventing telescoping movement of the housings when the latch is in the latching position and the actuator rods are moved to open the valve but permitting telescoping movement of the housings when the latch is released.
