Patent

CA 2454813

The present invention provides an interlock mechanism suitable for use with a blower-vacuum device, which comprises: a user-operable switch having a first condition for activating a motor of said blower-vacuum device and a second condition for deactivating said motor; a latch for engagement with a removable attachment of said blower-vacuum device; and a user-operable release button for disengaging said attachment from said latch; wherein said switch is operable to activate said motor only when the attachment is engaged with said latch, and said release button is operable to disengage the attachment from said latch only when said motor is deactivated; and wherein the first condition of said switch comprises a first position of said switch for activating said motor at a first speed of operation and a second position of said switch for activating said motor at a second speed of operation. Thus the fan of the blowervac can be driven by the motor at two different speeds of operation suitable for different usage conditions, even though the fan cannot be driven by the motor when the fan is exposed.
