Locking device having a guard lock for safety doors, comprising a mechanical actuator which can be fastened on a movable door part and a housing which interacts with the actuator and can be fastened to a door counterpart, which housing comprises a receptor to which the actuator can be inserted, and the housing comprises a locking element which is displaceable between an unlocked position, in which the actuator can be released, and a locked position, in which the actuator can be fixed relative to the receptor, wherein the actuator comprises an engagement tongue having an engagement recess for mechanical operative engagement with a head end of a locking element in form of an engagement plunger, the engagement plunger being guided in the housing so as to be longitudinally displaceable a spring-biased manner in the in a plunger longitudinal direction relative to an inner fixed bearing, being shaped as a bushing and carrying radially displaceable and fixable engagement elements which lock the engagement plunger at its inner contour in the locked position during a defined state, for which purpose the engagement plunger comprises an engagement stop at the inner contour which acts in the longitudinal direction.

A door interlock of the present invention includes an engaged part and an engaging part configured to lock a door in a door closed state. The engaging part includes: a locking member; a mounting member mounted to the locking member; a sim member inserted into a slit; a first fixing member; and a second fixing member. The first fixing member is configured to be inserted into a first lock through hole, a first sim through hole, and a mount through hole, thereby fixing the mounting member and the sim member to the locking member. The second fixing member is configured to be inserted into a second lock through hole and a second sim through hole, thereby fixing the sim member to the locking member.

A press cover anti-pinch device and an apparatus having a press cover is disclosed. The press cover anti-pinch device comprises: a connector arranged at a lower side of a cover body of the press cover and fixed to the press cover; and a support hinged to the connector and rotatably arranged in a supporting position or in a collapsed position, wherein when the support is arranged in the supporting position, the support swings down and supports the press cover on a supporting surface, and when the support is arranged in the collapsed position, the support is collapsed and the press cover is lowered. During use, when the press cover is in an opened state, the support swings down and supports the press cover on the supporting surface, so that the support provides a supporting force to the press cover.

An image forming system comprises a first housing, a second housing and a third housing. The second housing may comprise a motor, a first door and a first switch. The first switch is provided on an electrical path connecting a power supply and the motor, for switching between a first state and a second state and for switching from the first state to the second state. The third housing may comprise a load. When the first door is opened in a state where the first switch is in the first state, the first switch switches from the first state to the second state to cause supply of electric power to the load to be cut off.

A system for sensing a position of a locking bolt of an industrial locking switch includes an inductive circuit, a converter, and a master controller. The inductive circuit includes an inductive coil and a capacitor electrically connected in parallel. The inductive coil is positioned to receive a locking bolt of an industrial locking switch when the locking bolt is transitioned to a lock position. The converter is configured to convert a frequency of a current signal on the inductive circuit to a digital frequency value. The master controller is configured to generate a bolt detection signal in response to determining that the digital frequency value changes by an amount equal to or substantially equal to a defined frequency shift corresponding to a frequency shift induced by the inductive coil in response to presence of the locking bolt within the inductive coil's magnetic field.

Safety architecture for an automated work cell provides a barrier separating a work cell area from an operator or personnel area. The safety architecture enables personnel to conduct routine interactions with nonfunctioning motion platforms or positioning machines located in the work cell area through openings in the barrier separating the personnel area from the work cell area while other motion platforms or positioning machines in the work cell area continues to function.

A fall-protection system including a harness and a fall-protection apparatus with a lifeline bearing a connector configured to be connected to the harness; and, a fall-protection monitoring system with a base unit and with at least one sensor module configured to sense a condition of the connector and to communicate a signal indicative of the condition of the connector to the base unit.
