专利汇可以提供Quick replacement, slack take-up electric cord for lamps, radios, clocks and the like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 small appliances such as lamps, clocks, radios, etc. comprising a length of two-conductor lamp cord which is preferably coiled and permanently set in a helix, one end of the lamp cord having attached to it a conventional two-prong electric plug adapted to be inserted in a wall receptacle. The other end of the twoconductor cord carries, and extends into one end of a special elongate receptacle having a socket or recess at its other end, opposite the entrance of the two-conductor cord. Within the special receptacle are two metal connector pieces having sharp prongs, the latter being located at the inner end of the socket. The socket is of substantially oblong cross sectional configuration, whereby it is adapted to receive the freshly-cut end portion of the original, somewhat flat electric cord from the appliance, which cord has been cut close to the appliance. The receptacle also has a manually operable lever which is adapted to force the said cut end of the appliance cord laterally against the prongs, causing the latter to pierce the insulation of the appliance cord and make electrical connections thereto. Thus, replacement of a lamp or appliance cord involves merely cutting the cord an inch or so from the lamp base or appliance casing, inserting the cut cord end deeply in the receptacle of the replacement electric cord, and then operating the lever to cause the cut end to be impaled on the sharp prongs of the receptacle so that the prongs effect electrical connections to the conductors of the appliance cord. The plug of the replacement cord is then inserted in the wall receptacle, whereupon the installation is complete.，下面是Quick replacement, slack take-up electric cord for lamps, radios, clocks and the like专利的具体信息内容。

权利要求

1. A replacement electric cord for small appliances such as lamps, radios, clocks and the like, comprising in combination: a. a length of two-conductor electric cord comprising a plastic insulation of oblong cross section, and two conductors embedded therein and separated thereby, said cord comprising stiffening means constituted solely of said plastic insulation and conductors, 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 an open-ended socket of substantially oblong cross-sectional configuration for receiving the cut end portion of a similar-section 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 and electrically connected respectively to the conductors of said two-conductor cord, and e. manually operable means pivotally 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. said length of two-conductor electric cord being coiled into a cold-set helix which extends between the electric plug and the receptacle fitting.

2. A replacement electric cord as defined in claim 1, wherein: a. the length of two-conductor electric cord comprises a ''''flat'''' extruded plastic lamp cord, b. the plastic insulation of said lamp cord having a cold-set helical configuration and being capable of taking other stretched ''''sets'''' as the helix is stretched, c. said plastic lamp cord being incapable of resuming its initial tightly coiled helical configuration once it has been stretched out.

3. 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-one-piece 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 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.
