Abstract

Hinge, in particular for an oven, with a housing on which a lever arm is stored in a swingable manner, and is activated by a driving gear. In an improved hinge of this type, the driving gear is connected to a tappet, which is connected to exert pressure on the lever arm.

Claims

1. A hinge for an oven including,

a housing on which a lever arm is stored in a swingable manner, and is activated by a driving gear, wherein

the driving gear is connected with a tappet which exerts pressure on the lever arm and the tappet is disconnected from the lever arm at a first position during closing and a second position during opening.

2. The hinge according to claim 1, wherein the tappet has a pressure surface to exert pressure on the lever arm in a direction of an open position of the hinge.

3. The hinge according to claim 1, wherein the tappet has a pressure surface to exert pressure on the lever arm in a direction of a closed position of the hinge.

4. The hinge according to claim 1, wherein a closing spring exerts force on the lever arm in a direction of a closed position of the hinge.

5. The hinge according to claim 1, wherein a carriage stored and movable longitudinally is activated by the tappet and is connected with the lever arm.

6. The hinge according to claim 1, wherein a lever is connected to the driving gear or the carriage and to the lever arm.

7. An oven or similar device with a closing door, including one or several hinges including,

a housing on which a lever arm is stored, and is activated by a driving gear, wherein the driving gear is connected with a tappet, and

the tappet including two faces which exert pressure on the lever arm in two directions and the tappet is disconnected at a position at which a spring pulls the lever arm from contact with the tappet.

8. The oven or similar device according to claim 7, wherein the housing of the hinge or hinges is arranged in the oven or in the similar device.

9. The oven or similar device according to claim 7, including the hinge and one or several hinges that are not activated by the driving gear.

10. The oven or similar device according to claim 9, including the hinge, and a hinge that cannot be activated by the driving gear and that has a spring.

11. A hinge for an oven including,

a housing on which a lever arm is stored,

a driving gear and a spring connected to the lever arm, wherein

the driving gear is connected with a tappet which exerts pressure on the lever arm and the tappet is disconnected from the lever arm in a position at which a weight of an oven door exceeds a spring force.
