Patent ID: 7609025

Claim:
A kit comprising: a plurality of power tools, each power tool configured to operate at an operating voltage, the operating voltages of at least two of the power tools being different from each other; a plurality of receivers for charging the power tools, each receiver including a portable power source configured to provide an output charging voltage, the output charging voltages of at least two of the receivers being different from each other, the output charging voltage of one of the receivers being equal to or greater than the operating voltage of at least one of the power tools and the output charging voltage of an other of the receivers being equal to or greater than the operating voltage of at least one of the other power tools; and means for selectively horizontally, slidably engaging each receiver with only one or more power tools having an operating voltage equal to or greater than the output charging voltage of the receiver to charge said one or more power tools and said horizontally, slidably selective engagement means includes a plurality of terminal blocks, each terminal block having at least one horizontally oriented rib and at least one of the receivers defines a horizontally oriented slot configured to engage a respective slot with a respective rib on the receivers and said one or more power tools having an operating voltage equal to or greater than the output charging voltage of the receiver, each terminal block is associated with a respective one of the power tools, wherein some of the terminal blocks include the rib and some of the receivers defines a slot configured to horizontally receive the rib of at least one of the terminal blocks, the location of the rib of each terminal block depending upon the output voltage of the respective power tool and the location of the slot of each receiver depending upon the output voltage of the receiver.
