  • Patent number: 11199031
    Abstract: The disclosure relates to a motor vehicle lock arrangement for a closure element which is movably coupled to a motor vehicle body, wherein a motor vehicle lock is provided, which in the mounted state is arranged on the closure element or on the motor vehicle body. It is proposed that a servo drive is provided for exerting a driving force on the closure element in its opening direction, so that the closure element can be moved in a motorized positioning process from a closed position into a gap position, and in this way an engagement gap can be created between closure element and motor vehicle body.

  • Patent number: 7905521
    Abstract: A multi-point door latch adapted to fit in the stile of a door. The multi-point door latch includes a pair of hooks that are allowed to rotably pivot around a pair of eccentric cams. The eccentric cams are allowed to rotate inside of apertures located through the hubs of the hooks. The eccentric cams are geometrically centered inside the hubs of the hooks, and are kept in position via pins that are eccentrically orientated through cams. The multi-point door latch also includes an opening for receiving a turning mechanism. In addition, the turning mechanism is connected to a pair of toothed gear wheels that mesh with a toothed bar. The toothed bar is connected to a synchronizing link which simultaneously rotates the hooks to either an engaged or disengaged position. The multi-point door latch also includes stopping members, which prevent the hooks from rotating passed a certain point when the door latch is not engaged.

  • Patent number: 7178839
    Abstract: A latch assembly connected to a lock face of a sliding door includes two hooks which are connected to two activation plates respectively. Two rotation gears each have teeth engaged with the activation plates which are moved to pivot the two hooks when the two gears are rotated. A safety member is biased by a spring and includes a contact pin which movably extends through the lock face on the sliding door so that the safety member is pushed when the contact pin is pushed by a fixed door when the sliding door is in close position. The safety member further has an engaging pin which is removably engaged with the recess of the activation plate so that when the sliding door is in open position, the activation plate cannot be moved and the hooks are remained in the sliding door.

  • Patent number: 7040673
    Abstract: An oven lock mechanism has a latch that is moved between an unlatched and a latched position in response to movement of the door from an open to a closed position and a motor that turns a cam acting as a blocker to block the latch in the latched position when a cleaning cycle is initiated. The rotation of the cam also induces movement of the latch to cause the latch to pull the door in closer to the frame of the oven.

  • Patent number: 6572159
    Abstract: The actuating system has a handle pivoted about a handle axis on the door, an actuating part fixed on the handle and extending radially from the axis, and a damper fixed on the door adjacent the axis and having an input element. The actuating part is connected to the input element for displacement of the input element and operation of the damper on pivoting of the handle. The input element is rotatable about a damper axis and the connection is a positive rotational coupling. The coupling includes gear teeth on the actuating part and gear teeth on the rotary input meshing with the actuating-part gear teeth. More specifically the rotary input element is a gear wheel and the actuating part includes a sector gear in mesh with the gear wheel.

  • Patent number: 5951068
    Abstract: A lock for the locking of a sliding closure. The lock includes a housing (10) with a pair of hook shaped locking elements (11) which are mounted for counter-rotation within the housing. A handle (26) is mounted for rotation on the housing and is coupled to a gear wheel (23) which meshes with a pair of rack elements (30,32) which are located for sliding movement in the housing (10). A projection (34) from each rack element (30,32) engages in a curved slot (35) of the locking element (11). Consequently, rotation of the handle (26) results in a sliding movement of each of the racks (30,32) which causes the locking elements to move between a first position where the locking elements are substantially retracted in the housing (10) and a second position where the locking elements can latchingly engage with a strike.

  • Patent number: 5797635
    Abstract: A latch is provided for holding a pair of case parts together, of a type that includes a frame (40) having a dish (42) that can mount in a hole of a first case part and a hasp (20) that can engage a strike (16) on the other case part. A slide (70) that can slide vertically on a bracket fixed to the dish, carries a bolt (30) that can be turned to move the slide up and down. The hasp has a first has end (22) pivotally mounted on the upper end of the slide and having a free second hasp end (24) for engaging the strike. The slide (70) is of sheet metal, with opposite slide sides (131, 132) that are bent around edges (60, 62) of a strip-shaped bracket (50) that extends vertically.

  • Patent number: 5595409
    Abstract: The present invention provides an assembly for latching a moving panel relative to a frame in which the moving panel slides or glides. A keeper is secured to the frame, and a latch is secured to the moving panel in such a manner that the keeper and latch are adjacent one another when the moving panel is moved to a closed position within the frame. Rotation of a key or handle on the moving panel causes the latch to extend and capture the keeper and pull the moving panel toward the frame as it latches. The latch cannot capture the keeper until a spike extending from the frame deflects a button on the moving panel. When the moving panel is latched, the spike provides resistance to vertical movement of the moving panel relative to the frame.

  • Patent number: 4796932
    Abstract: A power release and pull-down unit particularly adapted for rear compartment panels of motor vehicles. An electric motor rotationally drives a planetary gear set which in turn drives a latch hook. Limit switches are provided to sense the position of the latch hook such that motor rotation stops once the hook reaches one of two dwell positions. A clutching mechanism is provided to prevent excessive torque from being exerted on the latch hook during panel closure. When the panel is closed against the power unit, the latch hook is moved downwardly to securely close the panel against its sealing gaskets. Movement of the latch hook stops once a cam lobe contacts a limit switch. When the operator wishes to open the panel, motor rotation occurs causing the latch hook to move upwardly and out of engagement with the panel latch striker bar.
