摘要:
Instant opening mechanism (100) of facade claddings that is configured as a safety element in case of emergency to allow rapid evacuation, while at the same time the preceptive safety against intruders is not sacrificed without altering the aesthetic set of the same and comprising essentially an electromagnet (102), that moves horizontally along the axis perpendicular to the axis defined by the facade, releasing a latch (103) and this a guiding claw (104), such that the complete removal of the protection through a guide (101).
摘要:
A barrier release mechanism (1) for a barrier (3) including at least one barrier latch (170), a latch actuation device (7) disposed adjacent the barrier (3) and coupled to the barrier latch (170), the latch actuation device being movable between an engaged position in which the latch actuation device (7) causes the barrier latch to be engaged thereby latching the barrier (3) and a disengaged position in which the latch actuation device (7) causes the barrier latch (17) to disengage thereby allowing the barrier (3) to be moved, the latch actuation device (7) being resiliently biased by a spring (6) into the disengaged position. A source of fluid pressure is in fluid communication with the latch actuation device (7) and a pressure control valve disposed intermediate the latch actuation device and the source of fluid pressure. The application of a predetermined fluid pressure on the latch actuation device (7) causes it move into the engaged position and a predetermined reduction of fluid pressure to the latch actuation device (7) causes it to move to the disengaged position.
摘要:
A safety system for alerting occupants of a fire or smoke occurring within a building in which the safety system includes a smoke detector associated with an electric door release mechanism of a locked door that is energised to unlock the door automatically in response to receiving a signal from a control unit which in turn receives a signal from a smoke detector when fire or smoke is detected so that the door is automatically opened by the electric door release mechanism being released by movement of an electrically operated striker plate to allow occupants trapped within the building to escape from the burning building, whilst allowing access to the building for emergency rescue personnel.
摘要:
A window (1) with an opening of the tiltable type for railway carriages wherein the tiltable portion (3) is hinged to the surround (5) of the window by means of a pair of aligned and axially sliding pins (12a, b) so as to define a first position, wherein they are engaged in housings (24) integral with the surround, and a second position wherein, following axial translation one towards the other, they are disengaged therefrom. The tiltable portion is also hinged, parallel to the pair of pins, to an intermediate cross member (11) of the window integral with the surround so that, when the pins are in the first position, the tiltable portion can only perform an angular movement of preset extent after the locking means (4) have been disabled manually, whereas, when they are placed in the second position, the tiltable portion rotates in relation to the cross member until it is fully tipped, the locking means being disabled after lowering of the tiltable portion as a result of disengaging of the ends of the pins from the respective housings.
