Abstract:
A window assembly having a window frame and at least one primary sash mounted in the window frame. The primary sash has a plurality of sash members forming a primary sash perimeter and a first glazing panel mounted in the primary sash perimeter. At least one secondary sash is pivotally attached directly to the primary sash perimeter along an interior surface thereof so that the secondary sash is rotatably movable between a closed position and an open position relative to the primary sash. The secondary sash has a plurality of secondary sash members forming a secondary sash structure and a second glazing panel mounted in the secondary sash perimeter. An air chamber is located between the primary sash and the secondary sash that is substantially closed to the interior of the building structure. At least one accessory channel is locating along at least one side of the secondary sash members.
Abstract:
The invention relates to a safety device for a motor vehicle provided with at least one closable opening of the interior, for example a sunroof or a side window, wherein an electric adjusting drive actuating a closing element is provided for closing said opening. Said invention is characterised in that a control unit evaluates safety-related data during travel in the case of an imminent crash and controls the electric adjusting drive in such a way that a rapid closing process is generated for the closing element by the electric adjusting drive in a current excess mode before said crash event occurs.
Abstract:
An operating system which utilizes a multi-functional wall station for a motorized barrier includes an operator for controlling movement of a barrier between various positions. The operator may receive signals from a wireless or wired wall station transmitter, a wireless keyless entry device and/or a portable remote transmitter device. The multi-function wall station provides for selective concealment of certain switches or buttons which are not commonly used in the day-to-day operation of a wall station. For example, the up/down switch may be actuated by a hinged cover which conceals other selected operational buttons and wherein those operational buttons are only accessed upon opening of the hinged cover. The wall station also provides a periodic lighting element so as to easily direct the user to push the hinge cover to initiate up/down movement of the barrier. The multi-function wall station also provides for an operational selection wherein the door may be closed in a normal manner; by an auto-close feature, wherein the door closes after a predetermined period of time; or a RF block mode, wherein the station prevents transmission of any remote radio frequency signals to the operating system. The auto-close feature may only be enabled upon actuation of a keyless entry device so as to allow the user to re-enter the garage in the unfortunate circumstance of being locked out of the garage.
Abstract:
A liftgate actuating assembly is disclosed for moving a liftgate of a motor vehicle between open and closed positions. The liftgate actuating assembly includes a motor that is fixedly secured to the motor vehicle. The motor has an output shaft capable of bi-directional rotation. A drive gear rotates about a drive shaft and is operatively connected to the output shaft to be rotated thereby. A cable drum is rotatably mounted to the drive shaft. The cable drum is coupled to the drive gear and is rotated thereby. The cable drum includes a cable wrapped thereabout between a drum end fixedly secured to the cable drum and a liftgate end fixedly secured to the liftgate. The cable is used to retract the liftgate from the open position to the closed position. A linkage is operatively connected to the drive gear. The linkage is from a retracted position to an extended position such that the linkage forces the liftgate from the closed position to the open position when the linkage moves from the retracted position to the extended position. The linkage includes a slot that provides lost motion within the linkage. This allows the liftgate to be move manually to the closed position without the motor being activated.

Abstract:
Rain sensor arrangement for an operator for a window, said window comprising a frame, a sash pivotable with respect to said frame, and a pane mounted in said sash. The operator is adapted for pivoting said sash between a closed and an open position and vice versa, and said operator is controlled via a control circuitry responsive to input signals from at least a rain sensor. The rain sensor has at least one sensing area arranged so as to be protected against rain by said window, when the sash is in the closed position.
Abstract:
A disengageable stop for a fire door or security gate includes a brake actuator for releasing a brake. An expandable linkage, havig a normal length and having an elongate length when an external force is applied thereto, has a first end connected to the brake actuator. A second end of the expandable linkage is connected to a fire condition sensitive device, which releases the second end upon a fire indicative condition. With the fire door, or any other type of door, a DC generator is connected to the door and produces power as the door moves from its open position to its closed position. A DC motor is also connected to the door and has an ability to move the door from its closed position to its open position. A first power terminal is connected to the motor, and adapted to receive a second terminal of a portable, rechargeable DC battery.
Abstract:
The invention relates to a sliding door system with at least one sliding door wings, preferably an automatic sliding door, with a running mechanism and drive and control means. Said drive and control means (2a, 2c, 2f, 2g, 28) are arranged in a receiving space (55) which is attached to the front of the running mechanism (1), the receiving space (55) and running mechanism (1) forming a substantially square, composite body. The lower edge of said body extends up to or engages over the upper edge of the wing, its overall vertical height is determined by the cross-section of the drive motor (2a) and/or by the overall vertical height of the running mechanism (1), and its overall horizontal width is at least twice as large as the overall vertical height. In a preferred embodiment, the running mechanism (1) takes the form of a box-shaped running mechanism section (63) with two vertical legs (63a, 63b) and a preferably square cross section. The one vertical leg (63a) is suspended by a suspension device (33) in a carrier member or carrier module (3) secured to the building, and connected to said carrier member by a clamping device (34). The second, front, vertical leg (63b) has a longitudinal groove (350) extending horizontally of a C or T-shaped form. The drive and control means (2a, 2c, 2f, 2g, 28) are held to be positioned in the groove in a variable manner either individually or in assemblies and are fastened by clamping pads (351) with clamping screws (352). Thus one obtains a sliding door system which has a particularly compact structure and a low overall height.
Abstract:
A time delay release mechanism (10) has a brake actuator (44) including an actuation member movable between engaged and released positions. A timer (110), when receiving electrical power (13) or when power thereto is interrupted for a duration less than a predtermined time period, disengages from the actuation member (44) allowing the actuation driver, when power thereto is initially interrupted, to move the actuation member (44) to the engaged position. The timer (110) engages the actuation member, when power to the timer is interrupted for a duration greater than the predetermined time period, to move the actuation member (44) to the released position thereby overriding the actuation driver to allow closure of the fire barrier (16). The timer (110) disengages from the actuation member (44) when power to the timer is restored and the actuation driver retains the actuation member in the released position when power to the actuation driver is restored, thereby automatically resetting the brake actuator (44) and timer (110).
Abstract:
An operating device for a door comprises a door closing device (6, 8, 10) that exerts a first torque on a rotatably journalled shaft (8), said torque via rotation of the shaft in a door closing direction being transferred to a closing torque on the door. An electric motor driven power mechanism comprises a driven gear (22) mounted for rotating, for opening the door, the rotatably journalled shaft (8) in a door opening direction. This power mechanism comprises first means which at manual opening of the door admit free rotation of the shaft (8) with respect to the driven gear (22), and second means for admitting, at need, rotation of the driven gear (22) with respect to the shaft (8) in the door opening direction.
