Abstract
A locking apparatus with tumbler for safety doors has a door part for fastening on a movable safety door and has a frame part for fastening on a door counterpart. The frame part has a receptacle and the door part has an actuator configured to be inserted into the receptacle. The frame part further has a blocking member which is displaceable between a release position, in which the actuator can be released in, and a blocking position in which the actuator is secured in the receptacle. The actuator is arranged on the door part via an elastic compensating element.
Claims13
A locking apparatus for safety doors having a movable door and a door counter part, said locking apparatus comprising:
- a door part designed for being fastened on the movable door, and
- a frame part designed for being fastened on the door counter part,
- wherein the frame part has a receptacle and the door part has an actuator configured to be inserted into the receptacle,
- wherein the frame part further has a blocking member which is displaceable between a release position, in which the actuator can be withdrawn from the receptacle, and a blocking position in which the actuator is secured in the receptacle,
- wherein the actuator is arranged on the door part via an elastic element made from an elastomer or a rubber material and configured to allow a limited rotational movement of the actuator relative to the door part so as to compensate for a vertical offset between the movable door and the door counter part,
- wherein the elastic element has a central receiving region and a plurality of webs arranged around the central receiving region in a cruciform or star-shaped manner and extending therefrom, and
- wherein the actuator has an actuator frame in which the webs are arranged, and wherein the door part has a receiving profile on which the receiving region is mounted.
A locking apparatus for safety doors having a movable door and a door counter part, said locking apparatus comprising:
- a door part designed for being fastened on the movable door, and
- a frame part designed for being fastened on the door counter part,
- wherein the frame part has a receptacle and the door part has an actuator configured to be inserted into the receptacle,
- wherein the frame part further has a blocking member which is displaceable between a release position, in which the actuator can be withdrawn from the receptacle, and a blocking position in which the actuator is secured in the receptacle,
- wherein the actuator is arranged on the door part via an elastic element made from an elastomer or a rubber material and configured to allow a limited rotational movement of the actuator relative to the door part so as to compensate for a vertical offset between the movable door and the door counter part,
- wherein the actuator has at least one blocking surface and the blocking member has at least one blocking counter surface, said at least one blocking surface and said at least one blocking counter surface cooperating for securing the actuator in the receptacle in a form-fit manner in the blocking position, and
- wherein the actuator has a recess adjacent to the at least one blocking surface, said recess defining a space into which the blocking member can at least partially advance in order to release the actuator.
A locking apparatus for safety doors having a movable door and a door counter part, said locking apparatus comprising:
- a door part designed for being fastened on the movable door, and
- a frame part designed for being fastened on the door counter part,
- wherein the frame part has a receptacle and the door part has an actuator configured to be inserted into the receptacle,
- wherein the frame part further has a blocking member which is displaceable between a release position, in which the actuator can be withdrawn from the receptacle, and a blocking position in which the actuator is secured in the receptacle,
- wherein the actuator is arranged on the door part via an elastic element made from an elastomer or a rubber material and configured to allow a limited rotational movement of the actuator relative to the door part so as to compensate for a vertical offset between the movable door and the door counter part, and
- further comprising a safety spring coupled to the blocking member for pushing the blocking member into the blocking position.
A locking apparatus for safety doors having a movable door and a door counter part, said locking apparatus comprising:
- a door part designed for being fastened on the movable door, and
- a frame part designed for being fastened on the door counter part,
- wherein the frame part has a receptacle and the door part has an actuator configured to be inserted into the receptacle,
- wherein the frame part further has a blocking member which is displaceable between a release position, in which the actuator can be withdrawn from the receptacle, and a blocking position in which the actuator is secured in the receptacle,
- wherein the actuator is arranged on the door part via an elastic element made from an elastomer or a rubber material and configured to allow a limited rotational movement of the actuator relative to the door part so as to compensate for a vertical offset between the movable door and the door counter part, and
- further comprising an unlocking mechanism coupled to the blocking member in order to manually move said blocking member from the blocking position into the release position.
