Abstract:
An unlock mechanism for a rotary door operator of a transit vehicle includes a pivotally disposed unlock member adapted for rotating a lock member into an unlock position and activating a valve for discharging the fluid pressure from the drive cylinder to enable manual opening of the door. A spring is provided for biasing the unlock member to a non-activated position. The unlock member may be activated either with a cable or a lever handle. A lock sensing switch provides a feedback on the lock condition to the transit vehicle control system. Additionally, a guiding bracket is provided for securing the cable in proximity of the unlock member.
Abstract:
A snap-in insert component for non-permanently closing an access opening fabricated near the top of the jamb of a sash window. Locating the access opening near the top of the window jamb avoids air infiltration problems in the window that result when the opening is located below the upper end of the lower sash of the window. The insert component, when inserted in the access opening, provides a bearing surface for a tilt latch on the lower sash when the sash is raised to the point of the access opening. This allows the sash to be raised all the way to the top of the window frame without experiencing un-desired movement in the in and out direction. The insert component can be readily re-moved and re-inserted in the field as the need arises. Because the insert component essentially completely fills the access opening, the appearance of the window is improved.
Abstract:
The invention relates to an opening device for a flap of a vehicle, in particular for a rear flap, which can be pivoted about a horizontal pivot axis on the upper edge of an opening in the vehicle body from a downwardly directed closed position into an upwardly directed open position. It has a gas-filled spring coupled to the body by the free end of its piston rod at a distance from the pivot axis and coupled to the flap by its pressure tube at a distance from the pivot axis. In this case, the gas-filled spring in the extension direction applies a force to the flap in the opening direction. Furthermore, there is an actuator by means of which a torque can act on the flap in the opening direction. The actuator is an energy accumulator which, from its tensioned position, applies a force to the flap during its opening stroke from the closed position until a relaxed position of the energy accumulator is reached.
Abstract:
A door opening and closing device having a rotational mechanism configured to switch a door between a closed position and an open position relative to a base member. The rotational mechanism has a supporting arm integral with the door; a sector gear portion provided on the arm; a rotating gear disposed on the arm at essentially a center of the arc of the sector gear; a first rack portion on the base member and configured to engage the sector gear; and a second rack portion on the base member. The second rack is essentially parallel to the first rack portion and separated by predetermined distance therefrom, the second rack being configured to engage the rotating gear.
Abstract:
A door or hatch capable of moving between an open and closed position and normally biased to revert to one of those positions is retained by a manually operable retaining means. A release means is provided to automatically release the door or hatch to thereby allow it to return to its biased position, automatically. The release means is operable in normal ambient temperature for automatically releasing the door or hatch and operable under fire conditions for automatically releasing the door or hatch.
Abstract:
When an ECU interrupts electric power supplying to an electromagnetic coil with a rotor, a rotor and an armature are controlled at a disconnected state, in which a driving force transmission between a vehicle door and a electric driving power source is interrupted and a manual opening and closing operation of the vehicle door is allowed. When the ECU supplies electric power to the electromagnetic coil, the rotor and the armature are controlled at a connected state, in which the driving force transmission between the vehicle door and the electric driving power source is performed. After the ECU activates the electric driving power source to perform one of an opening operation, and a closing operation, of the vehicle door, the ECU interrupts electric power supplying to the electromagnetic coil and activates the electric driving power source.
Abstract:
A cover opening and closing mechanism switches a cover body on a corresponding surface of a main body between a closed position for closing the corresponding surface and an open position for opening the same. The cover opening and closing mechanism includes a forcing device for always urging the cover body toward the closed position; a push button; a switching device having a cam facing the button, an acceleration gear engaging a gear part provided on the cover body, and a striker; and a latch device for locking the striker in the open position of the cover body and releasing the lock when the button is pushed. The switching device switches the cover body from the closed position to the open position against a force of the forcing device.
Abstract:
In an opening-closing mechanism of a door member for shifting the door member from a closed position for closing an opening portion of a base member to an open position and vice versa, the door member includes a pair of arm portions. Each arm portion includes a circular arc shape gear and a rotary gear disposed in a center of the circular arc of the gear. The base member includes a first fixed gear portion with internal teeth engaging the circular arc shape gear portion, and a second fixed gear portion disposed inside the first fixed gear engaging the rotary gear. The arm portion is held to move vertically through engagements between the first fixed gear portion and the circular arc shape gear portion and between the rotary gear and the second fixed gear portion, so that the door member is shifted along a path corresponding to the first fixed gear portion.
Abstract:
A system for moving a barrier between limit positions, includes an operator motor assembly mounted proximate to the barrier, wherein at least a portion of the motor assembly is movable between an operating position and a locking position with the motor assembly blocking movement of the barrier. A bias assembly biases the motor assembly in the operating position and allows the motor assembly to move toward the locking position when either a predetermined force overcomes a biasing force or when the barrier is moved to a closed limit position or when forced entry is imposed on the barrier. The biasing force may be adjusted by moving posts on the motor assembly that are engaged by the bias assembly. A disengagement feature may also be provided that allows pivotable movement of the motor assembly even when in a locking position. And the pivoting motor assembly may be used as a secondary entrapment input to an operator controller.
Abstract:
An emergency unlocking device for locking and unlocking systems for swinging sliding doors, in particular of rail vehicles. The emergency unlocking device has a traction device that engages on a first spring-loaded pivoted lever that is connected via a second lever to a third lever. The third lever is attached to the axial shaft of a spring-loaded rotary magnet and has elongate holes in which a bolt is displaceably mounted. When the traction device is subjected to tensile stress, the bolt engages with a fourth lever that is pivotably mounted on a shaft, and moves the fourth lever. The fourth lever is operatively connected via a coupling rod and deflection unit to a locking rod that moves the vertical direction. A rod, via which a force component that brings about the locking and unlocking of the door leaves can be applied, engages on the fourth lever.
