Abstract:
A device for opening and closing an outwardly opening pivoting wing, comprising: an actuating device including a support, a crank rotatable with respect to the support and a control mechanism actuated by the crank, an arm having a toothed portion, wherein said control mechanism cooperates with the toothed portion of the arm for swinging the arm between a closed wing angular position and an open wing angular position, and wherein in the closed wing angular position the control mechanism cooperates with the toothed portion of the arm for the translational motion of the arm along a straight direction between a locked wing position and an unlocked wing position, and vice versa, a first slider and a second slider intended to engage a groove of the wing in a movable manner in a straight direction.
Abstract:
A counterbalance system for a tilt-in window that utilizes a brake shoe assembly. The brake shoe assembly is comprised of a brake shoe housing and a cam element. The brake shoe housing has a first arm element, a second arm element, and a flexible bottom section. A cam opening is disposed within the brake shoe housing. A gap space exists above the cam opening. The cam element is disposed within the cam opening. The cam element contains a tilt post receiving slot that received the tilt post from a window sash. A catch finger extends from the first arm element into the gap space. The catch finger at least partially obstructs the tilt post receiving slot. This prevents the tilt post of the window sash from being inadvertently lifted out of the brake shoe assembly.
Abstract:
A composite pull-chain disc mechanism with brake function for a door operator comprises a torsional spring having de-twisting and twisting sides. The weight of a door curtain always acts on the de-twisting sides, so that the inner diameter of the torsional spring is induced to shrink to brake the rotation of the central shaft of the door operator. If twisting sides bears an external force, the inner diameter of the torsional spring is induced to enlarge to release braking of the central shaft. Furthermore, the composite pull-chain disc mechanism can be adapted to an electric door operator. In the case of detaching an electric motor mechanism during maintenance, the door operator can still be operated to open/close a door in a manual mode through the composite pull-chain disc mechanism.
Abstract:
A spring cycle tracker system for a door mounted on a track having at least one spring, with the door having an open and closed position. The system has at least one sensed element and a tracker. The tracker has a sensor having at least one sensing element; and a controller having a counter, at least one input signal from the at least one sensing element and at least one output signal. The sensed element and the tracker are mounted such that when the door is moved towards the open position and/or the closed position, the sensed element and the controller are moved adjacent to each other so that the sensing element senses the sensed element, sending an input signal to the controller, incrementing the counter, tracking a number of times the spring is used.
Abstract:
A sliding door mechanism includes an upper slide rail and a lower slide rail fixed to a vehicle side body structure. An upper slider is associated with the upper rail, and a lower slider is associated with the lower rail. An upper link includes a control arm pivotally connected to both the upper slider and a vehicle door. A lower link includes a control arm pivotally connected to both the lower slider and the vehicle door. A control mechanism is operatively associated with a selected one of the upper link and the lower link. The control mechanism includes a first control fixed to the vehicle side body structure and a second control fixed to the control arm of the selected link. Movement of the second control is based on predetermined structural constraints associated with the first control. The control mechanism controls rotation and translation of the upper and lower links.
Abstract:
The present invention relates to an actuator (1), comprising an output member (6); a resilient element (8) connected to said output member (6) so as to urge it in a first direction; and an hydraulic rotation damper (5) with a closed cylinder cavity, a rotational damper shaft which extends into the cylinder cavity, and a piston dividing the cylinder cavity into a first side and a second side. Within the rotation damper (5), the rotational movement of the damper shaft is converted into a translational movement of the piston along a longitudinal axis of the shaft. A restricted fluid passage communicates said first and second sides. The damper shaft is connected over a gearing (10, 15, 17) to the output member (6) and resilient element (8) of the actuator for damping movement of said output member (6) in said first direction.The present invention relates to both rotational and linear actuators as well as to a closing mechanisms for hinged members, such as doors, gates, or windows, comprising such actuators.
Abstract:
An opening and closing device opens and closes a sliding door by using a cable connected to the sliding door movably attached to a vehicle body. The opening and closing device has a base bracket, a motor, a transmission, a rotary drum, a first conduit fixed portion, a second conduit fixed portion, a first tension controller and a second tension controller. The base bracket is fixed to the vehicle body with bolts. The motor, the transmission, the rotary drum, the first and second conduit fixed portions and the first and second tension controllers are fixed to a disposition face of the base bracket. The first and second tension controllers are respectively disposed between the rotary drum and the first conduit fixed portion and between the rotary drum and the second conduit fixed portion, and applies tension to the cable fed from the rotary drum to take up the slack.
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:
The present invention relates to a hold-open apparatus for controlling the position of a door, preferably a screen door or storm door. The apparatus is used in conjunction with a piston assembly and can maintain a door in a predetermined open position, such as about 45° to about 100° in relation to a closed position. In a preferred embodiment, the apparatus can automatically lock and/or unlock when the door reaches predetermined positions. The apparatus advantageously can be retrofitted to existing door assemblies.
