Abstract:
This invention provides an existing garage door locking system with a motorized unlocking system that will unlock the garage door prior to motorized opening, but maintain garage accessability and security with the existing garage door locking system if a power or motorized garage door system failure occurs.
Abstract:
One or more spring lock devices are included at the inner sides of a conventional garage door positioned to engage with the side door frame. The spring locks are actuated to the open position by operative connection, usually through tension lines to a garage door drive mechanism, which is connected to the garage door through a lost motion mechanism so that initial movement of the drive mechanism moves the spring lock devices and opens them before the garage door mechanism moves the garage door. For closing, the spring lock devices can be of the wedge striker type which will close and lock with the closing motion of the garage door or of a straight pin type, in which case the door is adjusted so that its balance mechanisms always biases the door toward the closed position when the door is near its closed position.
Abstract:
In a motor operated overhead garage door the operator is connected to a bell-crank lever pivotally mounted on the garage door so that the first movement of the operator swings the bellcrank lever to retract a spring pressed locking device for locking the door in closed position. Further movement of the operator lifts the door in a conventional manner.
Abstract:
Die Erfindung betrifft eine Verriegelungsvorrichtung (10) für Schwenkschiebetüren von Fahrzeugen, insbesondere von Fahrzeugen für den öffentlichen Personenverkehr, umfassend mindestens ein in Längsrichtung des Fahrzeugs verschiebbares Türblatt und einen Antrieb (50) zur Bewegung des Türblatts zwischen einer geschlossenen und einer geöffneten Stellung, wobei die Verriegelungsvorrichtung (10) ein Gestänge (20; 30; 40) umfasst, das für eine Verriegelung der Tür in der geschlossenen Stellung in eine Übertotpunktlage bringbar ist. Sie ist dadurch gekennzeichnet, dass die Verriegelungsvorrichtung (10) eine Grundplatte (11) aufweist, auf der eine Verriegelungsplatte (20) und ein Umlenkhebel (40) in jeweiligen Lagern (13; 14) drehbar in einer Ebene parallel zur Ebene der Grundplatte gelagert sind. Der Umlenkhebel (40) und die Verriegelungsplatte (20) sind über einen jeweils gelenkig an diesen gelagerten Verriegelungshebel (30) miteinander verbunden, wobei der Umlenkhebel (40), der Verriegelungshebel (30) und die Verriegelungsplatte (20) durch Anlenkung des Verriegelungshebels (30) in eine Lage bringbar sind, in der die Verbindungslinie (VV) zwischen dem Lager (13) des Umlenkhebels (40) und dem Gelenk (32) zwischen dem Verriegelungshebel (30) und der Verriegelungsplatte (20) und die Verbindungslinie (VU) zwischen dem Lager (13) des Umlenkhebels (40) und dem Gelenk (31) zwischen dem Umlenkhebel (40) und dem Verriegelungshebel (30) in Übertotpunktstellung stehen. Diese Übertotpunktstellung ist durch eine entgegen gesetzte Anlenkung des Verriegelungshebels (30) auflösbar, wobei die Verriegelungsplatte (20), der Umlenkhebel (40) und der Verriegelungshebel (30) auf der gleichen Seite der Grundplatte (11) angeordnet sind.
Abstract:
The invention relates to a device for the automatic mechanical locking of a powered leaf. The inventive device is characterised in that: (i) the rods bearing the lock bolts comprise two sliding rods which perform opposite but parallel movements and which extend from a lock bucket (C), and (ii) the retractable stop element which clears the path of the sliding actuator is connected to a protruding part which is equipped with means for adjusting the position thereof. The retractable stop element can be adjusted in order to (i) adapt the distance between the leaf and the frame; and (ii) unblock the movement of the actuator (OC), dependent on the lock bucket (C), with the frame of the leaf (P1) or an insert, such that it is unblocked just before the leaf end of closing travel. The invention is further characterised in that it also comprises at least one spring which is used to re-position the stop element and the rods immediately following the start of the opening movement of the leaf (P1).
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:
A power door operator for transit vehicles utilizing a rodless pneumatic cylinder (10) to open and close doors (2, 3) in the sidewall of a vehicle. Door movement having a controlled door edge force is achieved through coupling an external piston (11) of the cylinder and vehicle doors through belt (16). Magnetic coupling between internal and external pistons of the cylinder provide force having breakaway value applied to the operated door. A novel lock (30, 31, 32, 33) operated by admission of air to the cylinder (10) latches or unlatches the door in its closed position subsequent or prior to door closing or opening. Control of door motion at the ends of its travel is achieved through the use of a novel differential area (10a) in the cylinder. Piston force is modified for positions approaching either end of the cylinder using a sliding rod (40) contained by the piston (10a). Movement of the rod modifies available force.
Abstract:
PROBLEM TO BE SOLVED: To allow a user to precisely recognize a shortage of opening position holding power of a tail gate, by preventing door closing by dead weight of the tail gate, when being likely to be insufficient in holding power of an opening position to the tail gate. SOLUTION: This vehicular opening-closing driving device can hold a full opening position of the tail gate, only by thrust of a gas stay, by arranging a motor 11 with a speed reducer, a clutch 12, and the gas stay 4 between a car body 2 and the tail gate 1; and forcibly drives door closing, after driving up to the full opening position, by connecting the motor with the speed reducer, when detecting the door closing by the dead weight of the tail gate, after separating the motor with the speed reducer. Thus, when the holding power of the opening position is insufficient, since a door is closed after fully opening once, cargo loading-unloading work can be performed during that time.

Abstract:
PROBLEM TO BE SOLVED: To accurately detect the presence of the abnormality of an opening holding means holding an open-close body at an opening position. SOLUTION: A clutch is disconnected at the time when the open-close body arrives at the opening position. When a travel of the body of a predetermined distance (L1) in the closing direction from the opening position at a time of disconnecting the clutch is detected within a predetermined clutch disengaging time (t1), the clutch is connected, and disconnected after an elapse of a predetermined specified time (t2), and a processing for detecting the descending quantity of the body within the time (t1) is executed repeatedly by a plurality of times.
