Abstract

Abstract A hinge pin is rigidly connected to a knuckle of the door leaf of a hinge, the jamb leaf of which has a passage extending through it from inside a knuckle forming part of the leaf to the outer edge of that leaf. The inner end of a rod slidably mounted in the passage is pressed against the pin by a spring. The jamb side of the jamb leaf has an opening therein exposing one side of the rod, which has a notch in it adjacent that opening. A push button electric switch is mounted in the opening with its button projecting into the rod notch while the door leaf is in one of its open and closed positions. The side of the hinge pin has a depression in it receiving the inner end of the rod while the door leaf is in one of said positions so that rotation of the pin as the door leaf is swung toward its other position will cause the rod to move lengthwise. One end wall of the rod notch is positioned to push the projecting switch button outwardly into the switch when the rod moves the notch away from said leaf opening.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 245 words
A door hinge comprising a jamb leaf and a door leaf disposed side by side and provided with tubular knuckles in axial alignment with one another, a pivot pin in said knuckles holding them in alignment so that the door leaf can be swung between open and closed positions, means rigidly connecting the pin to a knuckle of said door leaf, the jamb leaf having a passage extending therethrough from inside a knuckle forming part of that leaf to the outer edge of the leaf, a rod slidably mounted in said passage, a spring in the passage pressing the inner end of the rod against the pivot pin, the jamb side of the jamb leaf having an opening therein exposing one side of the rod, said side of the rod having a notch therein adjacent said opening, and a push button electric switch mounted in said opening with its button projecting into said notch while the door leaf is in one of said positions, the side of said pivot pin having a depression therein receiving the inner end of said rod while the door leaf is in one of said positions, whereby rotation of the pin as the door leaf is swung toward its other position will cause the rod to move lengthwise of said passage, and one end wall of said notch being positioned to push said projecting switch button outwardly into the switch when the rod moves the notch away from said opening.
Claim 2
Dependent Claim 245 words
A door hinge comprising a jamb leaf and a door leaf disposed side by side and provided with tubular knuckles in axial alignment with one another, a pivot pin in said knuckles holding them in alignment so that the door leaf can be swung between open and closed positions, means rigidly connecting the pin to a knuckle of said door leaf, the jamb leaf having a passage extending therethrough from inside a knuckle forming part of that leaf to the outer edge of the leaf, a rod slidably mounted in said passage, a spring in the passage pressing the inner end of the rod against the pivot pin, the jamb side of the jamb leaf having an opening therein exposing one side of the rod, said side of the rod having a notch therein adjacent said opening, and a push button electric switch mounted in said opening with its button projecting into said notch while the door leaf is in one of said positions, the side of said pivot pin having a depression therein receiving the inner end of said rod while the door leaf is in one of said positions, whereby rotation of the pin as the door leaf is swung toward its other position will cause the rod to move lengthwise of said passage, and one end wall of said notch being positioned to push said projecting switch button outwardly into the switch when the rod moves the notch away from said opening.
Claim 3
Dependent Claim 36 words
A hinge according to claim 1, including A plug rigidly mounted in the outer end of said passage, and said spring being a coil spring compressed between said plug and the outer end of said rod.
Claim 4
Dependent Claim 18 words
A hinge according to claim 1, in which said switch is adjustable toward and away from said rod.
Claim 5
Dependent Claim 27 words
A hinge according to claim 1, in which said pin depression is a notch having end walls connected by a substantially flat side wall engaging said rod.
