Abstract:
Vorrichtung für die Bewegung eines Torblattes, insbesondere eines Rolltorblattes, mittels eines sicherheitsüberwachten motorischen Antriebes, welche für den wahlweisen Bewegungsantrieb des Torblattes mittels Motor oder van Hand koaxial mit der Antriebswelle (2) des Antriebsmotors (1) fluchtend zwei weitere Wellen (19;20) aufweist, deren dem Rotor des Antriebsmotors benachbarte ein Getrieberad (4) trägt, das mit einem auf der Welle einer Sicherheitsschnecke (9) angeordnete Getrieberades kämmt, und die gegenüber der Rotorabtriebswelle einerseits und in Längsrichtung gesehen zu der zweiten weiteren Welle (18) andererseits mit Hilfe von Kupplungen (16;17) verbindbar ist, die im Normalfalle ausgekuppelt sind, wobei die weitere zweite Welle der Kupplung benachtbart eine Lastmomentsperre (20) aufweist, die an ihrer der Kupplung abgewandten Seite an eine Nothandkurbel (21) angeschlossen ist, derart, daß die beiden Kupplungen (16,17) im Falle des motorischen Antriebsausfalles eingeschaltet sind und die Lastmomentsperre (20) lediglich eine Drehmoment vond der Aufnahme für die Nothandkurbel (21) über die Kupplungen (16;17) auf die Antriebswelle des Rotors und auf das Getrieberadpaar (14,15), das zur Sicherheitsschnecke (9) führt, überträgt.
Abstract:
An operation cord that is excellent in durability is provided. According to the present invention, an operation cord comprising a cord whose both ends are coupled by means of a coupling portion is provided, the operation cord characterized in that the coupling portion has a first coupling part and a second coupling part which are coupled with each other directly or via a coupling member, one of the coupling parts or the coupling member adjacent to each other has a fitting protrusion, and the other of the coupling parts or the coupling member adjacent to each other has a fitting hole capable of fitting with the fitting protrusion, and the fitting protrusion is a solid body.
Abstract:
A height adjusting mechanism and a refrigerator comprising the same may be provided. The height adjusting mechanism may comprise: a hinge shaft (1); an adjusting member (2) for driving the hinge shaft (1) to rotate around an axis of the hinge shaft (1); a constraining member (3) for constraining a movement of the adjusting member (2) in an axial direction of the hinge shaft (1); and a base (4) with the constraining member (3) fixedly connected thereto, in which the hinge shaft (1) connected with the base (4) may be liftable in the axial direction of the hinge shaft (1) under the driving of the adjusting member (2).

Abstract:
A sliding door or window (4) comprising a fixed frame (7); at least one openable sash (53); at least one sliding unit (54) for the openable sash (53); an element (14) for controlling operating means designed to set the sash (53) from a sliding condition to a locked condition and vice versa; a handle (1) comprising a handle body (2) that can be recessed in a cavity (5) in the sash (53), a slider (3) and a lever (15); the slider (3) can move forward and backward alternately in a guide (12) in the handle body (2) in order to actuate the controlling element (14) under the action of the lever (15); the lever (15) is movable between two limit conditions, in a first of which the operating end (17) applies with a first zone of it (23) an opposing action on a first control profile (20b) of the slider (3), in such a way as to prevent translation of the slider (3) when the lever (15) is housed inside the handle body (2) and in a second of which the operating end (17) applies with a second zone of it (22) a pushing action on a second control profile (20a) of the slider (3), opposite the first profile (20b), in order to enable sliding of the sash (53) when the lever (15) protrudes from the handle body (2).
