Abstract:
Provided is a small plug door device capable of performing an opening/closing operation and a plugging operation with a door drive mechanism for causing a force in a vehicle front-rear direction to act on a door, and further applicable also to a one-panel sliding door. A slide base 12 is installed slidably in a vehicle width direction relative to a fixed base 11. A door drive mechanism 13 for moving one door 104 in a vehicle front-rear direction via a connecting portion 19 has a drive portion 13a including an electric motor 21, a drive wheel member 13b, a follower wheel member 13c, and an endless member 13d, and is installed on the slide base 12. A guide portion 15 guides a shaft portion 14 provided on the connecting portion 19 so as to move the shaft portion 14 in a vehicle width direction. In a double-speed rail 16 in which a pinion 16c is disposed between two racks (16a, 16b), one rack 16b is connected to the slide base 12, the other rack 16a is connected to the door 104 side, and the pinion 16c is connected to the connecting portion 19.
Abstract:
Self-closing device for sliding doors of the type comprising at least one sliding leaf (2) which is hung from an upper profile (3). Said device (1) comprises a drive belt (10) configured to be joined to the sliding leaf (2); a closing pulley (20), provided with elastic means (30), which is arranged on a first rotation axis (4) integral to the upper profile (3) and which engages with a first end (11) of the drive belt (10); and a brake pulley (40), provided with stopping means (50), which is arranged on a second rotation axis (5) integral to the upper profile (3) and which engages with a second end (12) of the drive belt (10) opposite to the first end (11), thus the rotation movement of both pulleys (20, 40) being connected by the drive belt (10).
Abstract:
The invention relates to a supporting and operating mechanism for a sliding door, including an upright strut (2) at the door's vertical edge, by way of which the supporting and operating mechanism is linked with a door (1). The upright strut (2) has its top end provided with at least two sets of rollers (3, 4), of which an upper roller set (3, 3) is adapted to roll along the top surface of a first horizontal track (5) and a lower roller set (4, 4) is adapted to roll along the bottom surface of the first horizontal track (5). The upright strut (2) has its bottom end provided with at least two sets of rollers (3, 4), of which an upper roller set (3) is adapted to roll along the top surface of a second horizontal track (6) and a lower roller set (4, 4) is adapted to roll along the bottom surface of the second horizontal track (6). The horizontal run of a belt or chain (10), drivable back and forth by the motor (9), includes an engagement point (13) which is attached to the upright strut (2).
Abstract:
Ce dispositif comprend des moyens d'entraînement de l'élément entre deux positions de fin de course et une unité de commande de ces moyens d'entraînement, cette unité étant apte à agir sur ces moyens pour interrompre et/ou inverser leur fonctionnement en fonction de la valeur (θ) ou de la variation (dθ/dt) d'un paramètre représentatif d'une interaction entre cet élément et un obstacle. Des moyens formant butée sont aptes à limiter le déplacement de l'élément au niveau de l'une des positions extrêmes, alors que la limitation du déplacement par ces moyens induit une variation (dθ/dt) de ce paramètre. L'unité de commande est apte à différencier (1004) une variation (dθ/dt) du paramètre représentative d'une interaction (Δt≤ΔT) avec un obstacle d'une variation résultant de l'action (Δt≤ΔT) des moyens de butée. L'unité commande différemment (1005, 1006) les moyens d'entraînement en fonction du résultat de la différenciation.
Abstract:
A drive unit 20 for a power operated vehicle closure 12 has a track 24, a guide 26 moveable along the track, a link 34 attached to the guide at one end and adapted to be attached to the vehicle closure at the opposite end, and a motor assembly 22 for moving the guide along the track. The motor assembly 22 has an electric motor 36 and a speed reducer driven by the electric motor that has a first stage and a second stage. The first stage includes a belt drive 40, 42, 44 and the second stage is a spur gear set 46, 48. Alternatively the first stage is a worm gear 140 and a mating helical gear 142. The worm gear preferably has a high lead angle and a high number of leads. The speed of the electric motor is reduced to about 1000 rpm or less in the first stage permitting the use of spur gears in the second stage while retaining quiet operation.
Abstract:
Getriebe für die übersetzende Verbindung zwischen der Abtriebswelle eines Antriebsmotors und einer Welle zur Bewegung und/oder Halterung eines Torblattes, insbesondere Wickelwelle für einen Rolltorpanzer oder Torsionsfederwelle für ein Deckengliedertor, welches Getriebe zur Erzielung eines besonders kleinen Platzbedarf seitlich des Torblattes zwischen der Getriebeeingangswelle (7) und der Getriebeausgangswelle (8), die je ein Getrieberad aufweisen (12,13), mehrere Zwischenwellen (9,10,11) aufweist, die je ein untereinander verdrehfestes Paar von Getrieberädern (14-18) unterschiedlichen Durchmessers aufweisen, derart, daß von der Getriebeeingangswelle aus gesehen jeweils ein Getrieberad kleineren Durchmessers (15,17,19) mit einem Getrieberad größeren Durchmessers (14,16,18) der im Getriebezug nächstfolgenden Welle über ein diese beiden Getrieberäder umschlingendes endlos ketten- oder riemenförmiges Treibglied (21) in Verbindung steht.
Abstract:
A garage door operator (20) for moving a garage door (26) between open and closed positions includes a head unit (28) for being held by a support structure positioned remote from the door (26) with the head unit (28) having a motor (48) and a drive wheel (60) with spaced teeth on its periphery for being driven by the motor (48). The operator (20) also includes an elongate rail (40) having a first end which is held by a support structure disposed adjacent and above the door (26) with the rail (40) including a pulley (46) located adjacent the first end. The rail (40) also includes a second end for being held adjacent to and in alignment with the drive wheel (60). The operator (20) also includes a drive belt assembly (34) for training about the drive wheel (60) and the pulley (46) and for being supported by the rail (40). The belt assembly (24) includes a length of a plastic belt (76) with teeth (78) on one surface thereof matching the teeth (42) on the drive wheel (60). The belt assembly (34) further includes a trolley (36) for connection to the garage door (26) and a first connector (82) for joining one of the plastic belt (76) to one end of the trolley (36). The connector (82) includes a belt clip (96) including a pair of spaced, aligned side walls (100,102) with one side wall (100) having an inside surface with undulations (106) corresponding to the teeth (78) of the plastic belt (76). The connector (82) further includes a clip holder (98) deformable from an as-formed position in which the holder can receive the side walls flanking the belt (76) with the belt teeth (78) aligned with the undulations (106), to a deformed position in which the holder firmly holds the side walls with the belt positioned therebetween.
