Abstract:
Zustandsdetektionsvorrichtung zur Verwendung für eine Schließvorrichtung. Zustandsdetektionsvorrichtung für eine Schließvorrichtung für eine Tür, ein Tor und dergleichen, wobei die Zustandsdetektionsvorrichtung ausgeführt ist zur Anordnung in einer in der Schließvorrichtung vorgesehenen Aufnahme eines Befestigungsmittels für einen Schließzylinder, und die Zustandsdetektionsvorrichtung eine darin angeordnete Öffnungszustandsdetektionseinrichtung aufweist zur Detektion eines geschlossenen Zustands der Tür, des Tors und desgleichen.
Abstract:
The invention relates to a lock, particularly a door lock for mortise locks, wherein the housing has a cylindrical housing section (1) and a U-shaped housing section (2) that radially protrudes therefrom, the lock bit (4) being seated on a lock bit shaft (5) that is rotationally disposed in an axial through hole in the cylindrical housing section (1), and a lock bit resetting device being provided. The device provides two reversing devices (8, 9), which mutually create the reversing motion of the lock bit shaft (5), each having a control cam extending in some regions obliquely to the lock bit shaft (5), wherein along the control com a first reversing element (8a, 9a), which is disposed on the outside of the lock bit shaft (5) and is rotationally connected thereto, engages in a second reversing element (8b, 9b), which can be displaced in the housing only axially and to which a return spring (11) applies tension. The control cams extending in some regions obliquely to the lock bit shaft (5) are mirror-inversely disposed with regard to each other in the two reversing devices (8, 9), and the second reversing elements (8b, 9b) can be displaced in the opposite direction in order to create the reversing motion of the lock bit shaft (5).
Abstract:
Ein Gehäuse (2) eines Schließzylinders (1) für ein Einsteckschloss (7) hat einen Profilabschnitt (5) mit einem Normprofil und eine Profilerweiterung (6). Der Profilabschnitt (5) mit dem Normprofil ist von einer Stirnseite des Gehäuses (2) bis zu einem Schließbart (4) geführt. Die Profilerweiterung (6) ist von dem Schließbart (4) beabstandet und nimmt eine elektrisches Speicherzelle (20) auf. Hierdurch vermag die Speicherzelle (20) große Abmessungen aufzuweisen und ermöglicht eine Vielzahl von Betätigungszyklen des Schließzylinders (1).
Abstract:
A cylinder lock (1) for use in a locking arrangement which comprises a barrel having a through passage (3), two locks (7) provided one at each end of the through passage (3) and a cam member (6) located between the locks (7) wherein the two locks are interconnected by a solid single bar member (12) and two sleeve members (13,14) located about respective ends of the bar member which are activated by the lock to operate the cam member (6) in the normal manner.
Abstract:
An anti-lock-picking or burglar-proof cylinder lock, of the type that comprises a body that is composed of two mutually coaxial cylindrical 5 bushes (6, 7) divided by a gap (4) and provided with respective radial expansions (10, 11) that lie on a radial plane with respect to the bushes (6, 7), respective plugs (8, 9) for actuating a bit (5) that rotates in the gap (4) being accommodated rotatably in the bushes (6, 7), the radial expansions (10, 11) being connected by a bridge-like portion (15); the lock further 10 comprises a receptacle (25) that is provided in the radial expansions (10, 11) and in which the longitudinal central plane is co-planar with respect to the radial plane, a plurality of laminations (20) being rigidly coupled by way of their opposite ends in the receptacle (25), each one of the laminations (20) that belong to the set of multiple laminations being made of a respective 15 material that has a specific mechanical strength and a specific behavior with respect to elastic and plastic deformation, each one of the sets of multiple laminations (20) being constituted by one of the possible combinations of laminations (20) of different materials.
Abstract:
A wafer-type tumbler and key comprises a sleeve (1), a cylinder (2), some wafers (3), some springs (4) and a key (5). A shaft (20) on the cylinder includes a first and a second semicircular columnar body (20a,b). Disposed at the front and rear ends of the first semicircular columnar body are a flange (22) and a drive section (23) and at the inner lateral surface of the first semicircular columnar body is an indentation (201) that provides for insertion into the second semicircular columnar body. On the first and second semicircular columnar bodies (20a,b), one or more slots (24a,b) are disposed to fasten with the wafers (3). In addition to facilitating the placement of the wafers (3) and springs (4) into the shaft, the slots (24a,b) enable the fabrication of a corrugated keyway (21) with a narrower width. The key (5) has a serrated blade, wherein a metal plate is punched to produce its sectional shape into a corrugated contour to prohibit theft.
