Abstract

Disclosed is electrical plug ejecting apparatus having an elongated housing adapted to transversely retain the electrical plug, the housing defining a pair of spaced compartments disposed on opposite sides of the retained plug with ejector springs latchably retained within the compartments by trap doors tripably released by pivotal movement of a trip lever in response to the lateral movement of the line cord coupled to the electrical plug.

Claims

1. An electrical plug ejecting mechanism, comprising:

a. an ejector housing defined by front and rear longitudinally extending wall portions, a centrally defined opening in said housing extending transverse to said longitudinal direction and through said front and rear wall portions,

b. means for retaining an electrical plug within said opening in a manner that allows the conductive prongs of said plug to forwardly extend from said front wall portion,

c. a pair of compartments within said housing longitudinally spaced from one another on opposite sides of said centrally defined opening,

d. a pair of ejector springs respectively disposed within said compartments,

e. a pair of doors forming a part of said front wall portion so mounted to said housing to respectively close off said compartments and maintain said ejector springs under compression when in such closed position,

f. latch means latching said doors in said closed position, and

g. trip release means including a trip lever for releasing said latch means from said latching position, thereby to allow said doors to open and release said ejector springs from compression, said trip release means being actuated in response to a force exerted on said trip lever in said longitudinal direction.

2. The mechanism as defined by claim 1 further including a guide block defining a longitudinally extending channel;

said trip release means further comprising a pair of trip release arms translatably receivable within said longitudinally extending channel, said trip lever being disposed intermediate said trip release arms and pivotally mounted to translate said trip release arms against, and for releasing, said latch means.

3. The apparatus as defined by claim 2 wherein said latch means comprises a pair of latch plates pivotally mounted at their base and respectively having latching edges adapted to latchably engage end portions of said doors.

4. The apparatus as defined by claim 3 further including springs biasing said latch means into latchable engagement with said doors.

5. Electrical plug ejecting apparatus, comprising:

a. an ejector housing defined by front, rear, and side wall portions defining therebetween a longitudinally extending cavity, pivotally mounted doors providing a portion of said front wall portion adapted for opening or closing off the entrance to longitudinally spaced compartments of said cavity,

b. means for retaining an electrical plug within, and transverse to, said housing intermediate said spaced compartments,

c. a pair of ejector springs respectively disposed within said compartments and attached to said rear wall portion,

d. latch plates respectively pivotally mounted adjacent said end walls and having latching surface edges adapted to latchably engage said doors,

e. a pair of springs secured to said end walls and adapted to bias said latch plates into latching engagement with said doors, and

f. trip release means for releasing said latch plates from latchable engagement with said doors, said trip release means comprising guide block means defining an elongated channel substantially coextensive with said longitudinally extending cavity, a pair of latch trip release arms translatably mounted within said elongated channel and having end portions adapted to engage the inside surface of said latch plates, a trip lever pivotally mounted intermediate said latch trip release arms and extending through an opening in said rear wall, the clockwise or counter-clockwise movement of said trip lever translating said trip release arms to force said latch plates out of latchable engagement with said doors, the remote end portion of said trip lever being connected with the electric cord associated with said electrical plug, whereby the lateral movement of said cord pivots said trip lever to release said ejector springs, thereby to eject said electrical plug from engagement with a wall socket.
