Problems solved by technology

[0005] During long runs, the physical effort required to initiate the dispensing operation can fatigue and strain the operator
Also, using physical force to initiate the dispensing operation often causes the spray head to inadvertently move from its ideal dispensing position
Additionally, many fluid dispensers are designed to simply hold the sprayer with little regard for the comfort of the operator holding the handle to operate the fluid dispensing system

Embodiment Construction

[0017] 1 and 2, a handle 10 for a fluid dispensing system includes a pair of proximity sensors or switches 14a, 14b and an activation control 72 ( Figure 4 ) of the package shell 12. Activation controller 72 is electrically connected to dispensing controller 16 of the fluid dispensing system via cable 18 to form the fluid dispensing system. A family of Ultra available from EFD Inc., East Providence, Rhode Island, USA (EFD Inc., East Providence, Rhode Island) TM The 2400 Series Dispensing Workstation, is an exemplary dispensing controller 16 that can be electrically connected to the handle 10. The end of the outlet 17 (FIG. 2) of the cable 18 from the enclosure 12 is designed to prevent entanglement with the workpiece intended to receive the dispensed fluid and includes a strain relief 20 integrally molded thereon. Encapsulation 12 consists of two opposing parts 12a, 12b assembled together with conventional fasteners 21 .

[0018] The enclosure 12 supports a fluid container,...

Abstract

A hand-held fluid dispenser (10) having an enclosure (12) for supporting a container (22) holding a fluid to be dispensed, and a method of operating such hand-held fluid dispensers. A first proximity sensor (14a) is located inside the enclosure immediately adjacent one side of the enclosure (12), and a second proximity sensor (14b) is located inside the enclosure (12) immediately adjacent an opposite side of the enclosure (12). An actuation circuit (44) is supported inside the enclosure (12) and is electrically connected to the first and second proximity sensors (14a, 14b). The actuation circuit (44) produces an actuation signal in response to detecting opposed digits of an operator being simultaneously in close proximity to the first and second proximity sensors (14a, 14b).

Description

[0001] related application [0002] This application claims the benefit of US Provisional Patent Application No. 60 / 525,486, filed November 26, 2003, the entire disclosure of which is hereby incorporated herein by reference. technical field [0003] The present invention relates generally to fluid dispensing systems, and more particularly to a handle for a fluid dispensing system, a fluid dispensing system using the handle, and a method of operating the dispensing system. Background technique [0004] Conventional handles for fluid distribution systems come in many different shapes and configurations. With some systems, the operator grasps a handle enclosing the fluid cartridge or sprayer and initiates the dispensing operation with a foot pedal. For other systems, the fluid sprayer is mounted in a handle that is held by the operator, and the dispensing operation is initiated by the operator actuating a thumb switch on one side of the fluid sprayer. However, all of these kn...
