Abstract
A platen press with a press toggle mechanism (43) having a driving member (14) and a press toggle column (44). The press toggle column (44) comprises a driven member (38), a first toggle lever (46) assigned to the driven member (38) and a second toggle lever (48) assigned to the driven member (38). The first toggle lever (46) has a first contact surface (50) and the second toggle lever (48) has a second contact surface (52). Both toggle levers (46, 48) contact each other via their contact surfaces (50, 52), and wherein both contact surfaces (50, 52) are convex-shaped.

A platen press comprising:
- a press toggle mechanism, wherein the press toggle mechanism has a driving member and a press toggle column, the press toggle column comprising:
- a driven member,
- a first toggle lever assigned to the driven member, and
- a second toggle lever assigned to the driven member,
- wherein the first toggle lever has a first contact surface with a convex shape and the second toggle lever has a second contact surface with a convex shape, and
- wherein the convex shape of the first contact surface of the first toggle lever contacts the convex shape of the second contact surface of the second toggle lever to form a movable hinge.
A press toggle column for a platen press, the press toggle column comprising:
- a driven member to be driven by a driving member of the platen press,
- a first toggle lever to support the driven member and including a first convex surface, and
- a second toggle lever to support the driven member and including a first convex surface,
- wherein the first convex surface of the first toggle lever contacts the first convex surface of the second toggle lever to form a movable hinge.
A press toggle mechanism for a platen press, the press toggle mechanism comprising:
- a rotatable driving member;
- and
- a press toggle column, the press toggle column comprising:
- a rotatable driven member to be rotated by a rotation of the rotatable driving member,
- a first toggle lever to support the rotatable driven member and including a convex surface, and
- a second toggle lever to support the rotatable driven member and including a convex surface,
- wherein the convex surface of the first toggle lever contacts the convex surface of the second toggle lever to form a movable hinge.
