发明名称 Self-switching electric cord reel
摘要 A self switching electric cord reel is disclosed in which a switch for energizing and de-energizing the electric cord is located on a housing of the reel itself. The switch is electrically serially connected with the electric cord and actuated by a pivotally mounted lever switch means, one arm of which operates the switch, and the other arm of which extends across an opening of the housing through which the electric cord passes. An enlargement of the electric cord contacts and pivots the lever switch means to operate the switch. The present self-switching electric cord reel is characterized by using a simpler and less expensive switch and design than formerly were employed, and by adapting the lever switch means to absorb or transmit the mechanical shock of its pivotal operation to the housing in preference to transmitting the shock to the switch.
