A single-articulation door hinge for supporting a door wing on a cabinet frame comprising: a base plate fastenable to the cabinet frame and having a top surface; a hinge arm fastenable to the door wing and having a bottom surface, the hinge arm having portions defining a catch opening; means for detachably connecting the hinge arm to the base plate with the hinge arm bottom surface and the base plate top surface in direct surface-to-surface contact, the connecting means comprising a catch spring having first and second depending and substantially parallel sides releasably engageable with the base plate and the hinge arm between the first and second depending and substantially parallel sides, the catch spring first side including a catch shank and the catch spring second side having a nose, the catch shank and nose disposed toward each other, the catch shank engaging a support shank of the base plate, and the nose engaging the catch opening of the hinge arm, and the catch shank and the nose of the catch shank exerting a resilient clamping pressure on the hinge arm and the base plate directly between the catch shank and the nose, the catch shank and nose of the catch spring being resiliently deflectable away from each other to release the clamping pressure therebetween and detach the hinge arm from the base plate, the catch spring also including a scroll spring disposed between the catch shank and the nose of the catch spring, the scroll spring biased toward the nose of the catch spring to engage and secure the catch spring against the hinge arm bottom surface.
- 2. The door hinge according to claim 1, wherein said catch spring includes a lever arm for releasing the catch spring.
- 3. The door hinge according to claim 1, said hinge arm having portions defining a hook opening, and said connecting means further comprising an interlocking hook extending from said base plate and enagageable in the hook opening.
- 4. The door hinge according to claim 1, further comprising a stop cam extending from said hinge arm and fitting against said base plate for positioning the hinge arm on the base plate.
- 5. The door hinge according to claim 1, wherein said catch spring includes a lever arm for releasing the catch spring.
- 6. The door hinge according to claim 1, wherein said catch spring has a portion connecting said catch shank and said nose of the catch spring, and said scroll spring is bent from said connecting portion between the catch shank and the nose of the catch spring.
- 7. A single-articulation door hinge for supporting a door wing on a cabinet frame comprising: a base plate fastenable to the cabinet frame and having a flat top surface; a support shank extending from the base plate; a hinge arm fastenable to the door wing and having a flat bottom surface, the hinge arm having portions defining a catch opening; means for detachably connecting the hinge arm to the base plate with the hinge arm flat bottom surface and the base plate flat top surface in direct surface-to-surface contact, the connecting means comprising a catch spring having first and second depending and substantially parallel sides releasably engageable with the base plate and the hinge arm between the first and second depending and substantially parallel sides, the catch spring first side including a catch shank and the second side having a nose, the catch shank and nose disposed toward each other, the catch shank engaging the support shank of the base plate, the nose engaging in the catch opening of the hinge arm, and the catch shank and the nose of the catch shank exerting a resilient clamping pressure on the hinge arm and the base plate directly between the catch shank and the nose urging the hinge arm flat bottom surface against the base plate flat top surface, the catch shank and nose of the catch spring being resiliently deflectable away from each other to release the clamping pressure therebetween and detach the hinge arm from the base plate, the catch spring also including a scroll spring disposed between the catch shank and the nose of the catch spring, the scroll spring biased toward the nose of the catch spring to engage and secure the catch spring against the hinge arm bottom surface.
- 8. The hinge as claimed in claim 7 wherein the hinge arm is one piece.
