专利汇可以提供Quick replacement, slack take-up electric cord with improved switch, detachable electrical connector means专利检索，专利查询，专利分析的服务。并且A quick replacement, slack take-up electric cord for lamps, clocks, radios, etc, comprising a length of two-conductor lamp cord coiled and permanently set in a helix, one end of the lamp cord having a conventional two-prong electric plug for insertion in a wall receptacle. The other end of the cord has a special elongate receptacle made with a recess at the end opposite to the entrance of the cord. The receptacle has a push-button switch and a flat base for support on a table surface. Within the receptacle are two metal connector pieces having sharp prongs located at the inner end of the recess. The recess is oblong in cross sectional configuration to receive a freshly cut end portion of the original electric cord from the appliance, where it has been cut close to the appliance. The receptacle also has a manually operable lever to force the said cut end of the appliance cord laterally against the prongs so as to make electrical connection thereto. Replacement of an old cord involves merely cutting the cord an inch or so from the appliance, inserting the cut cord end deeply in the receptacle recess and then operating the lever to impale the cord on the sharp prongs. The plug of the replacement cord is then inserted in the wall receptacle. The receptacle switch will now be conveniently accessible to switch the appliance on and off.，下面是Quick replacement, slack take-up electric cord with improved switch, detachable electrical connector means专利的具体信息内容。

权利要求

1. As a new article of manufacture, a replacement electric cord for small appliances such as lamps, radios, clocks and the like, comprising in combination: a. a length of all-one-piece two-conductor electric cord, b. a two-prong electric plug affixed to one end of said electric cord and having prong-type contacts continuously electrically connected respectively to the conductors of the cord, c. an electric receptacle fitting attached to the other end of the electric cord, said receptacle fitting having an open-ended socket of substantially oblong cross-sectional configuration for receiving the cut end portion of a similar-section all-onepiece cord of the appliance, said socket having an outer end which is open at the exterior of the fitting and having an inner end disposed in the interior of the fitting, d. said receptacle fitting having a pair of sharp prongs disposed at the said inner end of the socket, at least one of said prongs being continuously electrically connected to one of the conductors of said two-conductor cord, the other of said prongs being connectable to the other conductor of the cord, and e. exposed and accessible, manually operable lever and cam means carried by the receptacle fitting and adapted to force laterally against the sharp prongs the one-piece end portion of a cut electric cord of an appliance when said end portion is inserted in said socket, whereby both the prongs pierce the insulation of the inserted appliance cord end and make electrical contact respectively to the conductors thereof, f. switch means carried by said receptacle fitting, and g. connections between said switch means and the electric cord and a prong of the fitting for controlling the electrical circuit of the appliance.

2. A replacement electric cord for small appliances such as lamps, radios, clocks and the like, comprising in combination: a. a length of two-connector electric cord, b. a two-prong electric plug affixed to one end of said electric cord and having prong-type contacts electrically connected respectively to the conductors of the cord, c. an electric receptacle fitting attached to the other end of the electric cord, said receptacle fitting having a socket of substantially oblong cross-sectional configuration for receiving the cut end portion of a similar-section cord of the appliance, d. said receptacle fitting having a pair of sharp prongs disposed at the inner end of the socket and electricAlly connected respectively to the conductors of said two-conductor cord, and e. manually operable means carried by the receptacle fitting and adapted to force laterally against the sharp prongs the end portion of a cut electric cord of an appliance when said cord is inserted in said socket, whereby the prongs pierce the insulation of the inserted appliance cord and make electrical contact to the conductors thereof, f. switch means carried by said receptacle fitting, and g. connections between said switch means and the electric cord and a prong of the fitting, for controlling the electrical circuit of the appliance, h. said switch means comprising an upstanding push-button and an electrical contact actuated by the push-button, and i. a base carried by the receptacle fitting, adapted to rest on a table surface adjacent the appliance, thereby to facilitate actuation of the push-button.

3. A replacement electric cord as defined in claim 2, and further including: a. cooperable releasable latch means on the push-button and receptacle fitting, for maintaining the push-button in a depressed position, and b. means biasing the push-button to a raised, non-depressed position on the receptacle fitting.

4. A replacement electric cord as defined in claim 3, wherein: a. the means biasing the push button comprises a resilient switch blade constituting one of the switch contacts.

5. A replacement electric cord as defined in claim 4, wherein: a. one of said sharp prongs has a base portion constituting a switch contact which is cooperable with said switch blade.
