Abstract

Abstract A multiple pin electrical plug having a variety of pin combinations of varying geometry is able to accept the several voltage outlet supplies of the major countries of the world. The multiple pin electrical plug is so arranged that pins (P1 to P7 inclusive) are able to extend in a number of configurations dictated by the movement of a shutter plate (21) having a slider (22) that is movable to at least the same number of discrete positions, as said number of configurations.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 134 words
A multiple pin electrical plug for selectively providing electrical pins in different configurations corresponding to different electrical sockets, comprising: a plurality of selectively extendable pins; a shutter plate movable by a hand operated slider between a plurality of discrete positions for selecting one of said different configurations and permitting extension of predetermined ones of said pins, at least one pair of said pins being provided on a prismatic sliding member, said sliding member having guide rails said shutter plate having protuberances co-operating with said guide rails to permit said sliding member to be extended from or retracted into said plug when said shutter plate is in one of said discrete positions and to permit movement of said shutter plate into another discrete position, preventing retracting of said sliding member, when the latter is extended.
Claim 2
Dependent Claim 134 words
A multiple pin electrical plug for selectively providing electrical pins in different configurations corresponding to different electrical sockets, comprising: a plurality of selectively extendable pins; a shutter plate movable by a hand operated slider between a plurality of discrete positions for selecting one of said different configurations and permitting extension of predetermined ones of said pins, at least one pair of said pins being provided on a prismatic sliding member, said sliding member having guide rails said shutter plate having protuberances co-operating with said guide rails to permit said sliding member to be extended from or retracted into said plug when said shutter plate is in one of said discrete positions and to permit movement of said shutter plate into another discrete position, preventing retracting of said sliding member, when the latter is extended.
Claim 3
Dependent Claim 72 words
A multiple pin electrical plug as in claim 1, wherein said shutter plate selects among four different pin configurations, a first in which said plug provides an extended flat pin pair, a second in which said plug provides an extendable and retractable cylindrical pin pair, a third in which said plug provides an extended and not retractable cylindrical pin pair, and a fourth in which said plug provides three extended flat pins.
