Abstract:
Movable partition systems include an elongated drive member with fixed, offset ends extending along a track, a partition that is automatically and manually movable along the track, the partition hanging from a trolley disposed at least partially within the track, a motor carried by the movable partition configured to drive a rotatable drive member engaged with the elongated drive member, and a clutch coupled with the motor configured to engage or disengage the rotatable drive member from the motor. Methods of moving a partition along a track include actuating a motor carried by a movable partition to drive rotation of a drive member while a clutch mechanism is engaged, and manually moving the partition along the track while the clutch mechanism is disengaged. Methods of installing a movable partition system include coupling a trolley to a rotatable drive member and placing the trolley within a channel of a track.

An articulated device comprises a first member (4) that is provided with a first set of teeth fixedly connected thereto (20, 22). A second adjacent member (6) is provided with a second set of teeth fixedly connected thereto (24, 26). A coupling section (32, 38) is also provided on which the first set of teeth is hingeably supported around a first hinge axis (28, 34) and on which the second set of teeth is hingeably supported around a second hinge axis (30, 36) wherein the first set of teeth engages with the second set of teeth. A positioning device sets an angular position of the first and second members relative to the coupling section.
Abstract:
A coupling device connects an operator chain of a chain operator to a sash member (1) of a window. The coupling device comprises a securing means (10) adapted to be secured to said sash member (1), a first coupling member (3), which at a first end is designed for connection with said free end of said operator means (2) and at a second end has a mouth (5a) of a cut-out (5), and a second coupling member (6) comprising a shaft member (6a) rotationally secured to said securing means (10). Said shaft member (6a) comprises a connection section (8) with a first transverse dimension (a) corresponding to a width of said mouth (5a) and a second, larger dimension (b) corresponding to a width of said cut-out (5), and rotating means (7) for rotating said shaft member (6a). The coupling device further comprises an indicating means (11) secured to said securing means (10) and abutting said shaft member (6a) such as to indicate to a user, by operation of said rotating means (7), the rotational position of said shaft member (6a).
Abstract:
Die Erfindung betrifft einen motorischer Antrieb (40) für einen zumindest um eine Achse (14, 16) schwenkbaren Flügel eines Fensters oder einer Tür, mit einem Antriebsgehäuse (41) , in dem ein zug- und drucksteifes Übertragungsglied in Form einer Kette (42) aufgenommen ist, die über einen Motor aus dem Antriebsgehäuse (41) verlagerbar ist und die mit ihrem freien Ende an einem Lagerbock oder einer Konsole (43) angreift und die entlang einer Seitenkante (53) drucksteif und entlang der gegenüber liegenden Seitenkante (52) umlenk- bzw. abknickbar ist. Um einen universell einsetzbaren Antrieb (40) zu erhalten ist vorgesehen, dass die Kettenglieder (49) entlang der drucksteifen Seitenkante (53) Anschlagkanten (54) für das jeweils benachbarte Kettenglied (49) aufweisen, die einen Winkel der Kettenglieder (49) zueinander von mehr als 180° zulassen.
Abstract:
Die Erfindung betrifft ein Tor (10) mit: einem zwischen einer Schließendstellung und einer Öffnungsendstellung bewegbaren Torflügel (16), einem an einer zu verschließenden Toröffnung (30) anzubringenden stationären Torelement (12), an welchem der Torflügel (16) gehalten und geführt ist, wobei als Teil des stationären Torelements (12) eine Laufschienenanordnung (16) zum Führen und Halten des Torflügels (16) während dessen Bewegung vorgesehen ist, wobei die Laufschienenanordnung (14) auf einer Seite des Tores (10) eine erste Laufschiene (32, 110, 150, 202, 250) und auf der gegenüberliegenden Seite eine sich parallel zu der ersten Laufschiene erstreckende zweite Laufschiene (33) aufweist, wobei die erste (32, 110, 150, 202, 250) und die zweite Laufschiene (33) einen Bereich (20) des Torflügels (16) während seiner Öffnungs- und Schließbewegung hält und führt, wenigstens einem stationären Motorantriebsaggregat (40) zum Antreiben der Öffnungs- und Schließbewegung des Torflügels (16) und wenigstens einem Zugmittel (44), das das Motorantriebsaggregat (40) mit dem Torflügel (16) zum Übertragen von Antriebskräften verbindet. Um das Tor derart auszugestalten, dass es bei optimal an die Torbewegung angepasstem Antrieb kostengünstiger herstellbar und montierbar ist und weniger Bauraum benötigt, wird vorgeschlagen, dass das Zugmittel (44) und/oder ein daran angeschlossener Mitnehmerschlitten (52, 130) in der ersten Laufschiene (32, 110, 150, 202, 250) geführt ist und an einen in der ersten Laufschiene (31, 110, 150, 202, 250) geführten Teil (20, 58) des Torflügels (16) angeschlossen sind.
Abstract:
Releasable coupling (1) comprising a male part (2) and a female part (3), said male part (2) having a head portion (4), and said female part (3) having a base part (30) with a recess (6) for said head portion (4), said female part further having a yielding closure member (7) biased in a direction to at least partially cover the recess (6). To provide a coupling which is less demanding with regard to precise mutual positioning of the coupling parts at installation thereof, the closure member (7) is adapted for cooperation with said male part (2) in a first mutual angular position of the male and female parts (2, 3), in which the male and female parts (2, 3) are in non-positive engagement to allow release of the head portion (4) of the male part (2) from the recess (6), and a second mutual angular position in which the male and female parts (2, 3) are held in positive engagement by the closure member (7) to hinder release of the head portion (4) of the male part (2) from the recess (6).
Abstract:
A slim window actuator (1) for being mounted in a channel in a window frame (3) to operate the sash (4) of a pivot hung window. Typically, the cross-section of this channel measures about 25 by 25 mm. The window actuator comprises an elongated housing (10), in which a drive spindle is received. The drive spindle (12) is suspended from a first bearing (20) and a second bearing (38) and has an intermediate section (15) situated between the two bearings. At least one of the bearings (20, 38) is configured to provide the drive spindle (12) with an axially positive support reaction directed away from the intermediate section (15). A link mechanism (6, 76, 80) having a first part being (75) arranged displaceable along the drive spindle (12) and driven by the intermediate section (15) and a second part (7) for operating said sash (4). The second part (7) is displaceable in a substantially traverse direction away from or towards the housing (10) by rotation of the drive spindle (12). A drive motor (31) is disposed inside said elongate housing (10) and operably connected to said drive spindle (12).
