Door mounted hinge for oven doors and the like
First Claim
1. A hinge for mounting an oven door to close the oven cavity in a stove which has hinge mounting recesses adjacent the base of said cavity, said hinge comprising:
- (a) an elongated support member for mounting in a fixed position in the associated door and having a sidewall and a base wall defining a channel, said support member being adapted to be mounted along the side of the associated door in a position extending perpendicularly to its bottom edge;
(b) a generally L-shaped hanger having an elongated arm portion for seating in a recess of the associated stove and further having a depending hinge portion extending within said channel of the lower end portion of said support member;
(c) pivot means pivotably mounting said hinge portion of said hanger in said support member adjacent the lower end thereof;
(d) a translation member having a generally L-shaped lower portion pivotably mounted on said hanger arm portion and an upper portion extending vertically within said support member;
(e) an elongated spring substantially contained within said channel of said support member and having one end connected to said upper portion of said translation member and having its other end secured to said support member at a point adjacent its upper end; and
(f) cooperating means on said support member and on said translation member adjacent the upper end of said upper portion for utilizing the biasing force of said spring, whereby pivoting of the associated door from a closed to an open position causes displacement of said translation member towards the lower end of said support member and said pivot means and concurrent elongation of said spring to produce tensioning thereof, said cooperating means on said support member and translation member in the closed position of the hinge cooperating to bias the associated door into its closed position under the biasing force of said spring and also cooperating to hold the translation member in an intermediate open position of the associated door under the biasing force of said spring, and said translation member abutting and cooperating with said pivot means in the open position of the hinge to limit further pivoting thereof.

Abstract
An oven door hinge having stable positions in closed, broil and open positions of the door includes an elongated support member which extends along the side of the door, and a hanger with an elongated arm portion which removably seats in a recess adjacent the lower side of the oven cavity. The hanger also has a depending hinge portion which is pivotably supported on the support member adjacent its lower end. A translation member has its lower portion pivoted to the hanger arm portion, and an upper portion which is disposed within the support member. A spring is connected between the upper portion of the translation member and the upper end portion of the support member so that opening of the door displaces the translation member relative to the support member and hanger and tensions the spring. The support member and translation member have cooperating positioning elements to bias the door into its closed position and to hold the door in its broil position.

8. In combination,
(a) a stove having an oven cavity opening in the front wall thereof, a pair of recesses at the lower ends of the sides of said oven cavity, and a door dimensioned to close said opening; - and
(b) a pair of hinges mounting said oven door to close said oven cavity, each of said hinge comprising; (i) an elongated support member mounted along the side of said door in a position extending perpendicularly to its bottom edge, said support member having a sidewall and a base wall defining a channel; (ii) a generally L-shaped hanger having an elongated arm portion seated in one of said recesses on said stove and further having a depending hinge portion extending within said channel of the lower end portion of said support member; (iii) pivot means pivotably mounting said hinge portion of said hanger in said support member adjacent the lower end thereof; (iv) a translation member having a generally L-shaped lower portion pivotably mounted on said hanger arm portion and an upper portion extending vertically within said support member; (v) an elongated spring substantially contained within said channel of said support member and having one end connected to said upper portion of said translation member and having its other end secured to said support member at a point adjacent its upper end; and (vi) cooperating means on said support member and on said translation member adjacent the upper end of said upper portion for utilizing the tensioning force of said spring, whereby pivoting of said door from a closed to an open position causes displacement of said translation member towards the lower end of said support member and said pivot means and concurrent elongation of said spring to produce tensioning thereof, said cooperating means on said support member and translation member in the closed position of said door cooperating to bias said door into its closed position under the biasing force of said spring and also cooperating to hold said translation member in an intermediate door open position under the biasing force of said spring, and said translation member abutting and cooperating with said pivot means in the horizontal position of said door to limit further pivoting thereof. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)

16. A hinge for mounting an oven door to close the oven cavity in a stove which has hinge mounting recesses adjacent the base of said cavity, said hinge comprising:
-
(a) an elongated support member for mounting in a fixed position in the associated door and having a sidewall and a base wall defining a channel, said support member being adapted to be mounted along the side of the associated door in a position extending perpendicularly to its bottom edge; (b) a hanger having an elongated arm portion for seating in a recess of the associated stove and further having a depending hinge portion extending in the lower end portion of said support member; (c) pivot means pivotably mounting said hinge portion of said hanger in said support member adjacent the lower end thereof; (d) a translation member having a lower portion pivotably mounted on said hanger arm portion and an upper portion extending vertically within said support member; (e) an elongated spring in said support member and having one end connected to said upper portion of said translation member and having its other end secured to said support member at a point adjacent its upper end; (f) a roller on said upper portion of said translation member; and (g) a tab on said base wall of said support member projecting towards said roller and cooperating with said roller, whereby initial movement of the associated door from the closed position requires said roller element to deflect said translation member about its pivot and thereby increase the biasing pressure of said spring, and whereby further opening of the associated door causes displacement of said translation member towards the lower end of said support member and said pivot means and concurrent elongation of said spring to produce tensioning thereof, said tab and said roller on said translation member cooperating in the closed position of the hinge to bias the associated door into its closed position under the biasing force of said spring and cooperating to hold the translation member in an intermediate open position of the associated door under the biasing force of said spring, and said translation member abutting and cooperating with said pivot means in the open position of the hinge to limit further pivoting thereof.
