Abstract
The invention is directed to a cordlock retention mechanism for a power tool such as an automotive polisher. The housing includes a pair of electrical contact blades which may be plugged into an extension cord. The retention mechanism includes a lower stationary latch extending from the polisher housing and an upper latch which is pivotably mounted on the housing above the lower latch. The upper latch may be pivoted between an upper position in which it is out of contact with the lower latch to thereby allow access to the blades and a lower position where it is in contact with the lower latch to enclose a space. The lower latch includes a plurality of upwardly extending off-set ribs. The upper latch includes a downwardly extending transverse vertical plate which is disposed in front of the offset ribs when the upper latch is pivoted to the closed position. In order to provide electrical power to the polisher, the plug of the extension cord receives the blades and is disposed within the enclosed space. The upper latch is pivoted to the closed position and the vertical plate is positioned directly behind the rear of the plug to preclude the plug from being disconnected from the blade…
