In a preferred embodiment, the counter balancing spring mechanism is made of plastic and has an ear at the upper end thereof with an elongated slot opening the slot having a longitudinal axis substantially parallel to the longitudinal axis of the cylinder for mating with a pin inserted in an opening in a yoke bracket attached to the lower side of the cover.
Abstract: The counter balance system for a vehicle liftgate includes a pair of gas cylinders in combination with a torsion rod. The gas cylinders urge the liftgate toward an open position but due to a short moment arm do not exert sufficient force to open the liftgate until the liftgate has pivoted about one third of the distance from the closed position toward the open position. The torsion rod also urges the liftgate toward an open position. Maximum force is exerted by the torsion rod when the liftgate is closed. As the liftgate moves toward an open position, the force exerted by the torsion rod decreases until the liftgate is midway between closed and open. The torque rod does not exert any force on the liftgate during the last portion of its movement to an open position.

Abstract: An adjustable shutter assembly having an automated adjustment system including an electronic actuating device, such as an electric actuating motor. The shutter assembly has at least one and typically a plurality of parallel slats rotatably attached at both ends to a frame. The actuating motor is embedded within a self-contained module that can strengthen the shutter frame and be hidden from view. The actuating motor has a spindle that is coaxially connected to one end of an actuator slat selected from among the plurality of parallel slats. The spindle typically includes a tongue that engages a receiving pocket of the actuator slat without additional fastening mechanisms. One or more of the other slats are interconnected with the actuator slat such that rotation of the actuator slat is accompanied by substantially synchronous rotation of the other slats interconnected thereto. Selecting the actuator slat from among the more centrally located slats provides for more reliable and secure closure of all slats.

The mechanism is designed to support the cover and enable the cover to rotate through an angle greater than 90.degree. between an opened position and a closed position. The mechanism comprises an axle to be secured to the chamber, a support member having a first part rotatably supported by the axle and a second part spaced from the first part, a rotary member to be secured to the cover, the rotary member rotatably supported by the second part of the support member and capable of rotating around the support member when the cover is rotated, and a rotation-transmitting mechanism supported by the support member, connecting the rotary member to the axle to allow the support member to rotate in a first direction around the axle when the rotary member is rotated in a second direction opposite to the first direction.
Abstract: A lock assembly, for a door panel of a transit vehicle, has its locking action directly driven by the door operator into which it is incorporated. The locking assembly holds the door panel in a closed position through direct contact with the door panel, providing improved reliability by bypassing intermediate components of the door operator.
Abstract: A gate operator for lifting a gate about a horizontal axis at a lower proximate corner thereof to vertically raise and lower a gate in a generally 90 degree arc in the plane of the gate by using a fractional horsepower motor and an energy accumulator, which can be a torsion motor, a pneumatic mechanism or an enclosed spring mechanism. The motor is only used to initiate movement in the upward and downward cycles of the gate and to regulate the speed of the gate by damping the release of accumulated energy. A drive mechanism connects the motor to the energy accumulator. Energy is stored to the energy accumulator during the downward movement of the gate and released during the upward movement of the gate to reduce the amount of power required to operate the gate.
Abstract: The audio peephole for doors (T) comprises two flange bushings (2, 3), which are inserted into one another and held together by a two-piece screw-type optical spy-hole (1), with the flange bushings (2, 3) having in their flange (2a, 3a) a central reception hole (4) for the optical spy-hole (1) and at a distance around this central reception hole (4) a plurality of sound apertures (5) penetrating the flange (2a, 3a) and terminating in the hollow space (H) of the flange bushings (2, 3). These sound apertures (5) can be opened for sound transmission and closed against sound transmission by means of a manually rotatable apertured disk (6) provided behind the flange (2a) of the flange bushing (2) on the interior of the door.
