  • Patent number: 8733806
    Abstract: An actuating handle for a window or door including a fixing element coupled to a socket, the socket being selectively rotatable relative to a stop plate. The fixing element will allow insertion of a polygonal driver coupled to a handle from one direction through the socket, thereby rotationally coupling the handle and the socket, but will not allow the polygonal driver to be withdrawn in the opposite direction.

  • Patent number: 8210580
    Abstract: A detent assembly—namely of pairs of sub-assemblies of which the individual ones comprise spatially directly associated surfaces at which projecting elements cooperate with engaging elements in prestressed manner—comprises at least one detent element within a detent sub-assembly, said detent element being retained prestressed within an obliquely directed guide in a manner that it projects beyond a detent sub-assembly outer surface and that it enters an aperture sub-assembly while being obliquely prestressed into a recess of an opposite aperture outer surface and rests only unilaterally and point-wise against associated rim sites of the mutually associated interlocking zones. A preferred application relates to a handle being supported rotatably but in axially fixed position by a stop fitted with a disk connected to a handle extension and comprising circumferential interlocking recesses, for instance notches.

  • Patent number: 7934446
    Abstract: The invention relates to a firearm (10), in particular a single or multi-shot repeating rifle comprising a stock (11), a barrel (30) axially displaceable relative to the stock (11) and resting on or in a linear guide (20), a cartridge chamber to receive a cartridge being constituted in said barrel, further a breech (40) fitted with a breech cap (41) to seal the cartridge chamber and axially affixable in the barrel end (32) when the firearm (10) is closed, and further a locking unit (80) to lock the firearm into the closed position. The linear guide (20) comprises at least one guide rod (21), guide fork or the like linked or linkable to the barrel (30) and guided in sliding manner within the stock (11). This design leads to a compact and easily manufactured firearm with a slender and attractive appearance. The firearm (10) furthermore is made of fewer parts, resulting in simple disassembly and small shipping size.

  • Publication number: 20100225128
    Abstract: The invention relates to an actuating handle with a stop element for a door. The stop element comprises at least one attachment element that can be fixed to the door, a handle for actuating the door and/or a closure device arranged in the door. The attachment element, which is arranged and/or designed in such a way that it can be fixed at and/or in the closure device perpendicularly to the longitudinal axis of the stop element is connected with the stop element and can be introduced into the closure device by passing through a lateral surface of the door. In this way, the mounting of the actuating handle is made easier and can be carried out independently of the respective installation situation, if possible without tools.

  • Patent number: 7686357
    Abstract: An operating mechanism for building components such as windows, doors and the like comprises at least one handle and an actuating element that ca be made to engage the handle in a mutually non-rotational manner. A blocking device is situated between the handle and the actuating element and is designed so that the actuating element is insertable in a first direction into the handle whereas its displacement in the opposite direction is blocked.

  • Patent number: 7571671
    Abstract: A firearm (10), in particular a repeating shotgun, comprises a stock (11), a barrel (30) which is supported in axially displaceable manner relative to said stock (11) at or in a linear guide (20), a cartridge seat (31) to receive a cartridge (P) being configured in said barrel (30), further a closing system (40) fitted with a closing head (41) to close the cartridge seat (31), said closing head (41) being axially affixable in place in the barrel end (32, 33) when the firearm (10) is being closed and being traversed centrally to the barrel axis (A) by a striker pin (18), and a locking system (80) to lock the firearm (10) in its closed position. The closing system (40) is substantially configured axially symmetrically and/or rotationally symmetrically to the barrel axis (A).

  • Patent number: 7526887
    Abstract: A pump gun (10) comprises a barrel (11), a main stock part (12), a fore stock (12) supported in longitudinally displaceable manner and is linked to a breech lock (17) which, in the closed position of the pump gun (10), can be made to engage the rearward barrel end (21). The breech lock (17) and the fore stock (12) are linked to each other in a manner that upon displacing the fore stock (12), the breech lock (17) can be driven in the opposite direction to that of the fore stock (12). As a result, the pump gun (10) may be safely operated without recourse to a stop and, in the ready to fire initial state, is devoid also of any pumping excursion gap. The invention moreover offers a weapon matching marksman ergonomics and esthetics in its closed or ready to shoot state.

  • Patent number: 5775745
    Abstract: A latch and lockset system comprises a common unit having a socket (30) that houses a rotor (40) pivotably supporting a catch (50) on a pin (53) and attached to latch means (handles 20, 22). As the lockset (10) is assembled, its components (50, 53, 40, 33/34, 23) secure themselves successively. The unit is mounted in a transversal bore (Q) of a door leaf (T) by introducing a handle (20) sideways so as to point outwardly towards the free door edge whereby the common unit becomes seated in the transversal bore (Q); then the handle main portion (24) is pivoted by 180.degree. to reach its idle position in which the handle (20) is biased by a returning spring block (34) on the rotor (40). A guide bush (18) radially screwed into the socket (30) for securing it in a longitudinal bore (L) receives a spring-biased bolt (15).

  • Patent number: 5752727
    Abstract: A drive type operating mechanism for locking gates, windows, double-wing doors and the like includes push rods which are movable longitudinally in opposite directions to effect locking of the upper and lower ends of the door with the surrounding framework. The mechanism is connected for actuation by a lever handle through an arrangement of follower elements that are slidable supported in a lock case. A nut sleeve follower which is rotatable by the lever handle has one claw which cooperates with a groove in one longitudinally movable follower, and a second claw which cooperates with a transversely slidable intermediate follower which in turn cooperates with a groove in the second longitudinal follower, this arrangement ensuring that upon rotation of the handle the followers (and hence the locking bolts) move in opposite directions. A lock mechanism ensures that the longitudinally movable followers are not inadvertently moved from their end limiting positions.
