摘要:
A selvage for a secondary wing of fire doors, of the type comprising a body provided with gears constituted by at least one laminar element (13), with which respective vertically sliding sliders (19) are associated, the sliders engaging in corresponding receptacles, one in the threshold and one in the lintel of the opening where the door is installed, the element being actuated by a panic bar for opening. A ring (25) is centrally pivoted on the bottom of the body and perimetrically with respect to the at least one laminar element (13), a rotation of the ring (25) being associated with the translational motion of the at least one element (13); the ring (25) is provided with a toothed edge (27), proximate to which a pawl-type lever (23) is pivoted, the lever being provided with a tooth (24) that can engage removably the toothed edge (27) by means of the forcing of an elastic means (28), the ring (25) being blocked when the tooth (24) is engaged in the toothed edge (27).

An elevator door lock includes a locking member (40) that moves into an unlocked position responsive to contact with at least one door coupler member (32, 34). In disclosed examples, the locking member (40) comprises an arm that is pivotally supported by one of the door coupler members (34). The other coupler member (32) contacts a contact portion (42) on the locking member (40) to move the locking member into an unlocked position as the first coupler member (32) moves toward the second coupler member (34). In a disclosed example, a magnetic coupling between the coupler members maintains the locking member (40) in an unlocked position.

Es wird ein Kantriegel für setzholzfreie zwei- oder mehrflügelige Fenster, Türen und dergleichen mit einem am unterschlagenden Flügel (1) verschiebbar geführten, durch einen im Flügelfalzbereich (4) gelegenen Hebel (8) betätigbaren Riegelelement (15) beschrieben, dem blendrahmenseitig ein Schließteil (16) zugeordnet ist, wobei der Hebel (8) als im Eckbereich (20) des unterschlagenden Flügels (1) angelenkter Klapphebel ausgebildet ist, der im entriegelten Zustand im vertikalen Flügelfalzbereich (4) und im verriegelten Zustand im horizontalen Flügelfalzbereich (5) gelegen ist, und dass der Klapphebel (8) über ein angeschlossenes Gestänge (11,13,14) zumindest ein im horizontalen Falzbereich (5) des unterschlagenden Flügels (1) verfahrbares und mit einem blendrahmenfesten Schließteil (16) zusammenwirkendes Riegelelement (15) betätigt.
摘要:
A selvage (1) for secondary wing of fire doors which is fully reversible, of the type which comprises a body provided with gears associated with respective vertically sliding sliders (19), gears associated with an antipanic opening handle, which comprise two contoured and superimposed plates (13) which can slide axially within the selvage (1) and are contoured at one end so as to form a pusher (15), an angular spring (M) which has one arm which rests on the rear wall (3) of the selvage (1) and another arm engaged on an element which is rigidly coupled to the plates (13) in order to keep their end faces rested respectively against the upper wall (4) and the lower wall (5) of the selvage (1), two lever arms (12), which are rigidly coupled to the bits (11) and rest against elements which are rigidly coupled to the plates (13). The body is symmetrical with respect to a horizontal plane which passes through the centerline and is provided with two symmetrical bits (11), each individually adapted to engage the antipanic handle. The elements rigidly coupled to the plates (13) are rockers (24), which are pivoted substantially at their centerline to the respective plate (13) and in which the end that lies opposite to the contact end for the lever arms (12) can be rigidly coupled selectively to the respective plate (13).
摘要:
The invention relates to an arrangement (1) for an automatic flush blot (2) for pivotally mounted closing elements (3) which comprises a bolt (4) accommodated at the top and/or at the bottom in the aforementioned closing element (3) that is capable of automatic actuation by a pivotally mounted falling plunger (5) causing it to move vertically (6) into a position in which the closing element (3) is caused to close. The falling plunger (5) exhibits a bow-shaped curved actuating edge (8), and the aforementioned pivoting falling plunger (5) is also attached via a pivot arm (10) to the bolt (4) or to a motion transfer mechanism (9) capable of actuating it.
摘要:
Verriegelungsvorrichtung für mindestens dreiflügelige Fenster und Türen ohne Mittelpfosten mit innenliegender Schlagleiste (22, 23) bestehend aus einem Riegel (25) und einem Schließstück (32), wobei der Riegel (25) am Flügelrahmen (5) angebracht ist, der an zwei benachbarte Flügelrahmen (3, 4) angrenzt, wobei der Flügelrahmen (5) von einem der benachbarten Flügelrahmen (3 oder 4) an der Drehachse mittels der innenliegenden Schlagleiste (22, 23) übergriffen wird und der Riegel (25) mit einem der übergreifenden Flügelrahmen (3 oder 4) verriegelnd zusammenwirkt.
摘要:
The present invention relates to a locking device for doors, intended for connection between the dead-bolt (1) of the door and the drive means (2) of the lock. The invention is characterized in that a hinged arm (6) is connected to the dead-bolt (1) or its extension (5), a wheel (7) or pin being arranged at the other end of the arm (6) and designed to tumble into a recess (8) in a pivotable cam-disc (9), or to be disengaged from this recess by means of a link mechanism (11), whereupon in the latter position the cam-disc (9) is arranged to block the dead-bolt (1) in the first position and upon tumbling into the recess (8) to release it, and also that the dead-bolt (1) has an inclined surface (3) designed, upon pressure against the dead-bolt, to assist in the opening process.
摘要:
Eine zweiflügelige Tür (1) ist mit einer Verriegelungsvorrichtung ausgestattet, die einen Riegelverschluß (5) zum Verriegeln des Standflügels (4) gegenüber dem Türstock (2) und ein Türschloß (6) zum Verriegeln des Gangflügels (3) gegenüber dem Standflügel (4) und/oder dem Türstock (2) umfaßt. Um eine einfache und doch funktionssichere Türverriegelung zu erreichen, weist die Verriegelungsvorrichtung im Sturzbereich des Türstockes (2) ein Betätigungsorgan auf, das aus einer an einem Ende um eine zu den Flügelschwenkachsen schwenkbarem Gangflügel (3) angelenkten Schubstange (9) und einem am anderen Ende der Schubstange (9) angelenkten, in einer sturzparallelen Längsführung verschiebbar geführten Gleitstück (11) besteht, wobei ein Verschlußteil (13) des Riegelverschlusses (5) mit dem Gleitstück (11) verbunden ist.
