Abstract
A cord guard for an electrical power supply cord, such as the power cord of an electric pressing iron, includes a flexible strain relief sleeve having a central passageway therethrough and an outwardly-flared bell at one end of the strain relief sleeve open to the central passageway. The central passageway is adapted to snugly receive an electrical power supply cord along the entire length of the passageway. To this end, the passageway is formed with minimal draft. The strain relief sleeve may be formed by a tubular body having a plurality of parallel, equally spaced, V-shaped grooves extending circumferentially therearound, or the strain relief sleeve may be formed by an open spiral body having a uniform outside diameter along its length. The cord guard permits bending through at least 180 degrees without kinking the power cord, prevents twisting of the power cord within the cord guard, and reduces stress on the power cord at the point at which it exits the cord guard.
