Closing mechanism for cabinet hinge
First Claim
1. A self-closing mechanism for a fully concealed hinge, which has a hinge cup for mounting in a bore in a door, and a frame wing pivotally supported by the hinge cup for mounting on the door frame, said self-closing mechanism comprising:
- at least one cam surface on the hinge cup, said cam surface having at least three portions, a first portion corresponding to a fully open position of said door, a second portion corresponding to an almost closed and closed position of said door, and a third intermediate portion, between said first and second portions, corresponding to a position of said door between fully open and almost closed positions,a force generating assembly movably secured to the frame wing, said force generating assembly including a housing, and at least one spring retained by said housing, said at least one spring exerting a compressive force between said frame wing and said cam surface, whereby the compressive force when applied to said first portion results in a torque retaining the door in the fully open position, when applied to said second portion results in a torque for closing and retaining the door in the closed position, and when applied to said third portion does not apply a torque to the door.

Abstract
A self-closing mechanism for a fully concealed hinge, which has a hinge cup for mounting on a door, and a frame wing pivotally supported thereon for attachment to a frame on which the door is mounted. The mechanism includes a combination compression coil spring retainer and plunger which is mounted on the frame wing, and positioned to be pressed against cam surfaces provided on the hinge cup. The cam surfaces are formed such that force applied to the cam surfaces by the plunger will act to maintain the door in open and closed positions, will apply a force to close the door when approaching the closed position, and otherwise will not exert either an opening or a closing force on the door.

13. A self-closing mechanism for a fully concealed hinge, which has a hinge cup for mounting in a bore in a door, and a frame wing pivotally supported by the hinge cup for mounting on the door frame, said self-closing mechanism comprising:
-
at least one cam surface on the hinge cup, said cam surface having at least two distinct portions, a first portion corresponding to an almost closed and closed position of said door, and a second portion, corresponding to a position of said door between a fully open and an almost closed position, a force generating assembly movably secured to the frame wing, said force generating assembly including a housing, and at least one spring retained by said housing, said at least one spring exerting a compressive force between said frame wing and said at least one cam surface, whereby the compressive force when applied to said first portion results in a torque for closing and retaining the door in the closed position, and when applied to said second portion does not apply a torque to the door. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
