Abstract
The present invention generally relates to an interlocking device and in more particular to an interlocking device with a rotary latch that receives a latching bolt. In operation, the rotary latch can swing out of a release position into a locked position, by means of the bolt engaging a coupling jaw of the rotary latch. When the rotary latch is in a locked position, a safety element in an arresting position prevents rotary latch from swinging into its release position.
Claims15
An interlocking device comprising:
- a rotary latch having a coupling jaw;
- a latching bolt received within said rotary latch, wherein said rotary latch can swing out of a release position into a locked position for locking, by way of said bolt engaging said coupling jaw of said rotary latch;
- a safety element, wherein when said rotary latch is in the locked position, said safety element in an arresting position prevents said rotary latch from swinging into the released position;
- and
- a control element arranged relative to said rotary latch and said safety element, wherein said control element detects a presence of said bolt in said coupling jaw and releases said safety element to move into said arresting position when said bolt is inserted into said coupling jaw and wherein said control element triggers a movementof said safety element into said non-arresting position and a movement of said rotary latch into said release position when said bolt is removed from said coupling jaw.

An interlocking device comprising:
- a rotary latch having a coupling jaw, said rotary latch biased toward a release position by a spring;
- a latching bolt received within said rotary latch, wherein said rotary latch can swing out of the release position into a locked position for locking, by way of said bolt engaging said coupling jaw of said rotary latch;
- a safety element, wherein when said rotary latch is in the locked position, said safety element in an arresting position prevents said rotary latch from swinging into the released position;
- and
- a control element arranged relative to said rotary latch and said safety element, wherein said control element detects a presence of said bolt in said coupling jaw and releases said safety element to move into said arresting position when said bolt is inserted into said coupling jaw.

An interlocking device comprising:
- a rotary latch having a coupling jaw;
- a latching bolt received within said rotary latch, wherein said rotary latch can swing out of a release position into a locked position for locking, by way of said bolt engaging said coupling jaw of said rotary latch;
- a safety element, wherein when said rotary latch is in the locked position, said safety element in an arresting position prevents said rotary latch from swinging into a released position;
- and
- a control element arranged relative to said rotary latch and said safety element wherein said control element detects a presence of said bolt in said coupling jaw, whereby the inter-cooperation of said rotary latch, safety element, and control element forces said rotary latch into said release position when said bolt is not in said coupling jaw, wherein said control element is designed as a two-armed lever, and wherein when said rotary latch is in the release position, one lever arm of said control element covers said coupling jaw of said rotary latch under the effect of a spring.

An interlocking device comprising:
- a rotary latch having a coupling jaw;
- a latching bolt received within said rotary latch, wherein said rotary latch can swing out of a release position into a locked position for locking, by way of said bolt engaging said coupling jaw of said rotary latch;
- a safety element, wherein when said rotary latch is in the locked position, said safety element in an arresting position prevents said rotary latch from swinging into the released position;
- and
- a control element arranged relative to said rotary latch and said safety element, wherein said control element detects a presence of said bolt in said coupling jaw and releases said safety element to move into said arresting position when said bolt is inserted into said coupling jaw;
- wherein said rotary latch, safety element, and control element are pivotally mounted in two opposite side walls of a casing.
