  • Patent number: 7038154
    Abstract: The present invention provides an actuating device suitable for remotely actuating a tool which can be the fluid delivery mechanism of a cleaning implement. The actuating device has a flexible tape attached at one end to a spring-loaded spool mechanism connected to a trigger where the spring loaded spool mechanism is located within a housing for holding the device. The tape is threaded through at least one pole segment and is attached to a tool which can be actuated by a pulling or pushing motion of the tape. The present invention also provides a pair of electric cables which are attached at one end to the spring-loaded spool and at the other end to an electric tool or device such as a motor for driving a pump. An electric switch, which is located on the housing of a pistol-grip, is used to close the electric circuit formed by the pair of cables.
