Abstract
Abstract An electric power coupler for use with first and second door members relatively movable along a predetermined path toward and away from substantial abutment has a first frame mounted on the first door member. An inner pair and an outer pair of first frame electrical connectors are mounted on the first frame in a recess therein having a lateral opening in the direction of the path. The first connectors have exposed surfaces parallel to the path. At least some of the connectors are resilient in a direction normal to the path. The second frame is mounted on the second door member and supports a plunger for movement in a direction normal to the path. The plunger is spring urged to project, and cam surfaces on the first frame and the second frame cause the plunger to retract. The plunger has opposite walls partly defining a chamber therein having a lateral aperture confronting the recessed opening. An inner pair and an outer pair of second frame electrical connectors are respectively disposed on the opposite walls. The second connectors have exposed surfaces parallel to the path and in position to engage the exposed surfaces of the first connectors. At least some of the second connectors are resilient in a direction normal to the path. Flexible conductors join the second connectors to terminal posts on the second frame.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
154 words
An electric power coupler for use with first and second door members relatively movable along a predetermined path toward and away from substantial abutment comprising a first frame adapted to be mounted on said first door member, a first electrical connector having a first exposed surface, means for mounting said first connector on said first frame with said first exposed surface parallel to said path, a second frame adapted to be mounted on said second door member, a plunger, means for mounting said plunger on said second frame for movement normal to said path, a second electrical connector having a second exposed surface, means for mounting said second connector on said plunger with said second exposed surface parallel to said path, means for urging said plunger in a direction normal to said path to abut said connectors with each other, and a conductor mounted on said second frame and engaging said second electrical connector.
Claim 2
Dependent Claim
154 words
An electric power coupler for use with first and second door members relatively movable along a predetermined path toward and away from substantial abutment comprising a first frame adapted to be mounted on said first door member, a first electrical connector having a first exposed surface, means for mounting said first connector on said first frame with said first exposed surface parallel to said path, a second frame adapted to be mounted on said second door member, a plunger, means for mounting said plunger on said second frame for movement normal to said path, a second electrical connector having a second exposed surface, means for mounting said second connector on said plunger with said second exposed surface parallel to said path, means for urging said plunger in a direction normal to said path to abut said connectors with each other, and a conductor mounted on said second frame and engaging said second electrical connector.
Claim 3
Dependent Claim
25 words
A coupler as in claim 1 including means for resisting said urging means and stopping said plunger in a position projecting from said second frame.
Claim 4
Dependent Claim
39 words
A coupler as in claim 2 including means defining camming surfaces on said first frame and said plunger for moving said plunger against said urging means when said door members move along said path toward and substantially into abutment.
Claim 5
Dependent Claim
47 words
A coupler as in claim 1 in which said first and second door members move up and down relative to each other and in which said first and second exposed surfaces when in abutment with each other remain in contact as said members move up and down.
Claim 6
Dependent Claim
58 words
A coupler as in claim 4 including additional exposed surfaces on said first frame and said plunger spaced from said first and second exposed surfaces and in which said additional exposed surfaces when in abutment with each other remain in contact as said members move up and down and remain spaced from said first and second exposed surfaces.
Claim 7
Dependent Claim
49 words
A coupler as in claim 1 including a first additional connector having an exposed surface adapted to yield in a direction normal to said path, and means for mounting said first additional connector on said first frame in a location alongside of but spaced from said first electrical connector.
Claim 8
Dependent Claim
47 words
A coupler as in claim 1 including a second additional connector having an exposed surface, means for mounting said second additional connector on said plunger in a location alongside of but spaced from said second electrical connector and with said exposed surface thereof parallel to said path.
Claim 9
Dependent Claim
183 words
An electric power coupler for use with first and second door members relatively movable along a predetermined path toward and away from substantial abutment comprising a first frame adapted to be mounted on said first door member, said first frame having a recess therein with an opening laterally in the direction of said path, at least a first electrical connector extending parallel to said path, means for mounting said first connector on said first frame in said recess and directed toward said opening, a second frame adapted to be mounted on said second door member, a plunger having a chamber therein with an aperture open laterally in the direction of said path and complementary to said opening, means for mounting said plunger on said second frame for movement relative thereto in a direction normal to said path, at least a second electrical connector extending parallel to said path, means for mounting said second connector on said plunger and in said chamber directed toward said aperture and toward said first connector, and a conductor on said second frame and joined to said second connector.
Claim 10
Dependent Claim
183 words
An electric power coupler for use with first and second door members relatively movable along a predetermined path toward and away from substantial abutment comprising a first frame adapted to be mounted on said first door member, said first frame having a recess therein with an opening laterally in the direction of said path, at least a first electrical connector extending parallel to said path, means for mounting said first connector on said first frame in said recess and directed toward said opening, a second frame adapted to be mounted on said second door member, a plunger having a chamber therein with an aperture open laterally in the direction of said path and complementary to said opening, means for mounting said plunger on said second frame for movement relative thereto in a direction normal to said path, at least a second electrical connector extending parallel to said path, means for mounting said second connector on said plunger and in said chamber directed toward said aperture and toward said first connector, and a conductor on said second frame and joined to said second connector.
Claim 11
Dependent Claim
31 words
A coupler as in claim 8 in which said second connector includes a pin mounted on said plunger to move relative to said plunger in a direction normal to said path.
Claim 12
Dependent Claim
16 words
A coupler as in claim 9 including a spring urging said pin out of said plunger.
Claim 13
Dependent Claim
19 words
A coupler as in claim 10 including a stop for limiting movement of said pin out of said plunger.
Claim 14
Dependent Claim
