Abstract:
A device for driving a door or the like guided in at least two guides has a driving unit (1) arranged in a section designed as a guiding rail (2). The driving unit (1) consists of a driving pinion (4) linked to a driving motor, at least one deflecting pinion (5), one chain that runs over driving pinion (4) and deflecting pinion (5) and at least one element secured to the chain for entraining a door leaf or the like. A device with an easy-to-mount, simple design is achieved in that the driving pinion (4), the deflecting pinion (5) and the chain are designed together with the guiding rail (2) as a completely pre-assembled unit (1).
Abstract:
Eine Vorrichtung zum Öffnen von Kipptoren, und zwar insbesondere von sogenannten nicht-ausschwingenden Kipptoren, weist eine Hebelanordnung (40), bestehend aus im wesentlichen drei Hebeln (42,46,52), auf. Ein Hebel ist am Torblatt (1) befestigt und ist mit einem längenveränderlichen Hebel (52) verbunden, der einen spitzen Winkel (101) zum Torblatt (1) aufweist. Durch den dritten Hebel (42) werden die Endpunkte der beiden anderen Hebel miteinander verbunden. Eine Zugeinrichtung (38,72), welche mit dem Schlitten (11) eines herkömmlichen Torantriebes verbunden ist, greift am längenveränderlichen Hebel (52) an. Durch die Anordnung wird bewirkt, daß zum Beginn des Öffnungshubes ein Drehmoment auf das Torblatt (1) ausgeübt wird, das das automatische Öffnen des Torblattes erst ermöglicht.
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 door opening and closing apparatus includes a lock mechanism having an engaging member that engages with a lock member provided in a door when the door is in a fully closed state, and a link mechanism that has three link members, is configured to be able to undergo deformation into a linear state and a bent state, and restricts rotation of the engaging member by being brought into the linear state. A central link member among the three link members has a first face and a second face that are pressed by a projecting shaft. The link mechanism changes to the bent state when the first face is pressed, and changes to the linear state when the second face is pressed. The first face and the second face are provided so as to have a positional relationship in which the first face and the second face intersect each other.
Abstract:
A system of ejecting a sliding door of a closet, comprising a plurality of ejection assemblies and a connecting mechanism, which connects one assembly to the other. Each ejection assembly comprises a rail and a slidable member configured to slide along the rail, where the rail engages with a frame of the closet. The connecting mechanism allows synchronizing the ejection force applied upon the door at different locations of the door, by connecting the ejection assemblies through the connecting mechanism. This configuration allows ejecting and retrieving of the door outwardly and inwardly by sliding the slidable member of each assembly along the rail.
Abstract:
A drive mechanism for a door operator comprises a drive member and a driven member. The drive member is adapted to be operably connected between a motor assembly for rotating the drive member and a door closer assembly rotating with the driven member. The drive member and the driven member both include a protrusion. The driven member protrusion moves in the free space defined by driving surfaces of the drive member protrusion. Rotation of the drive member from a first angular orientation to a second angular orientation causes rotation of the driven member for powered opening of the door. The driven member protrusion moves in the free space without engaging the protrusion surfaces when the door is opened manually and allowed to close.
Abstract:
A synchronous pull device for slide cover mechanism includes two guide members, two slide seats and two pull assemblies. Slide guide sections are disposed on each guide member, whereby the slide seats can slide along the slide guide sections. First connection ends and second connection ends are respectively disposed on opposite sides of the slide seats. Each pull assembly includes at least two idlers, a middle idler and a pull cord. The two idlers are positioned beside two different ends of two different slide guide sections on opposite sides of the two guide members. The middle idlers are disposed between the two guide members near two ends of the slide guide sections. Each pull cord sequentially goes from the first connection end of one of the slide seats through one idler, the middle idler and the other idler to connect with the second connection end of the other slide seat.
