An extension arm device for releasably holding, manipulating, and remote operation of conventional trigger pump spray containers having a manual trigger pump spray head thereon. The extension arm is an elongate tubular member having a mounting receptacle at a distal end for releasably receiving and securing the trigger pump spray container and pump spray head thereto, a handle and trigger assembly at the proximal end, and an actuator rod connected to the trigger assembly at the proximal end extending through the arm and having an opposed outer end configured to engage and operate the trigger of the trigger pump spray head. Manual reciprocation of the trigger assembly at the proximal end is transmitted to the pump spray head trigger by the actuator rod to pump liquid from the container and discharge it through the nozzle of the spray head.

The invention claimed is: 1. An extension arm for holding, manipulating, and remote operation of a conventional trigger pump spray container of the type having a manual trigger pump spray head containing a pumping mechanism, a spray nozzle at a front end, a trigger connected with the pumping mechanism, a trigger return spring for returning the trigger to an extended position after it has been squeezed, and a liquid conducting dip tube that extends into the container, the extension arm comprising: an elongate arm having a hand grip and trigger assembly at a proximal end, and a mounting receptacle at a distal end for releasably receiving and securing the trigger pump spray container and pump spray head thereto in a vertical position generally perpendicular to said elongate arm; and actuating means having a proximal end connected with said trigger assembly, and having a trigger engaging portion at a distal end for engaging and operating the trigger of the pump spray head received in said mounting receptacle; wherein manual reciprocation of said trigger assembly at the proximal end of said elongate arm is transmitted by said actuating means trigger engaging portion to the pump spray head trigger and pumping mechanism to pump liquid from the container through the dip tube and discharge it through the spray nozzle. 2. The extension arm according to claim 1 wherein said mounting receptacle is configured to receive and secure conventional trigger pump spray containers and pump spray heads of different sizes and shapes. 3. The extension arm according to claim 1 wherein said elongate arm is a tubular arm; and said actuating means extends through the interior of said tubular arm and its said trigger engaging portion extends outwardly from the distal end of said arm. 4. The extension arm according to claim 3, wherein said actuating means comprises an elongate rod extending axially through said tubular arm connected at a proximal end with said trigger assembly, and its said outwardly extending end is bent to form said trigger engaging portion. 5. The extension arm according to claim 1, wherein said hand grip and trigger assembly comprises a pistol grip and trigger member pivotally connected at an upper end thereto. 6. The extension arm according to claim 1, further comprising: a second hand grip member on said elongate arm disposed between said hand grip and trigger assembly and said mounting receptacle. 7. The extension arm according to claim 1, further comprising: clamping means on said mounting receptacle configured to receive and releasably grip the pump spray head of the conventional trigger pump spray container. 8. The extension arm according to claim 7, wherein the manual trigger pump spray head of the conventional trigger pump spray container has a back end; and said clamping means comprises a retractable clamping member configured to receive and releasably engage the back end of the pump spray head. 9. The extension arm according to claim 8, wherein said mounting receptacle has a front end configured to receive the spray nozzle at the front end of the manual trigger pump spray head. 10. The extension arm according to claim 9, further comprising: adjustment means on said mounting receptacle engaged with said retractable clamping member for adjusting the distance between said mounting receptacle front end and said clamping member to accommodate pump spray heads of different sizes. 11. The extension arm according to claim 9, further comprising: resilient biasing means on said mounting receptacle engaged with said retractable clamping member to normally bias said clamping member to a forward extended position and releasably clamp the pump spray head of the conventional trigger pump spray container between said clamping member and said mounting receptacle front end. 12. The extension arm according to claim 9, further comprising: retracting means engaged with said retractable clamping member for retracting said clamping member to a rearward retracted position to allow installation and removal of the pump spray head between said mounting receptacle front end and said clamping member. 13. The extension arm according to claim 1, wherein the conventional trigger pump spray container has an externally threaded neck portion and the manual trigger pump spray head has an internally threaded cap at its bottom end threadedly engageable with the threaded neck portion; said mounting receptacle has a flat planar portion with an aperture for receiving the threaded neck portion of the container, a bottom surface engageable with the container beneath its threaded neck portion, and a top surface for engaging a bottom surface of the threaded cap; and said flat planar portion is clamped between the bottom surface of the threaded cap when the threaded cap is threadedly engaged with the threaded neck portion of the container and tightened thereon. 14. The extension arm according to claim 13, wherein said mounting receptacle aperture comprises a central longitudinal slot having all opening extending therefrom to the outer periphery of said flat planar portion; said longitudinal slot and said opening having a width of sufficient size to slidably receive the neck portion of the container beneath its threaded portion to allow installation and removal of the pump spray head. 15. The extension arm according to claim 1, further comprising: resilient means in said hand grip and trigger assembly connected with the trigger member of said trigger assembly to urge said actuating means trigger engaging portion to a forward extended position after squeezing pressure is relaxed during manual reciprocation of said trigger assembly.
