Patent number: 11359421Abstract: A compression latch includes a cylindrical housing (1). A locking shaft (2) is rotatably and axially movable in the housing. The locking shaft includes an axial free end (14) that engages a locking element (12). A cylindrical sleeve (3) engages an axial end of the locking shaft opposed of the free end. The sleeve includes an axially tapered annular sleeve slot (19) in which a shaft engagement pin (7) is engaged to cause axial movement of the locking shaft with rotational movement sleeve until the pin engages a slot end. After pin engagement with the slot end, further rotation of the sleeve causes rotation of the locking shaft. A cylindrical securing element (4) is rotatably engaged with and is axially movable relative to the sleeve. The securing element includes a circumferentially extending guiding recess (17) and a transversely extending latching recess (18).Type: GrantFiled: September 20, 2016Date of Patent: June 14, 2022Assignee: EMKA BESCHLAGTEILE GMBH & Co KGInventors: Friedhelm Runge, Michael Backhaus

Patent number: 8517435Abstract: An espagnolette lock for a door or shutter. An actuating shaft can be rotatably mounted within the interior of a housing and can be coupled with a lock-actuator. The actuating shaft is monolithically formed with a tongue. A securement mechanism is configured for insertion into the housing parallel to the plane of a door panel or of the shutter for fixing the housing in position on the door panel or shutter. The securement mechanism is further configured for being supported against the door panel or shutter. When a mounting of the espagnolette lock is completed, the securement mechanism is configured to engage the actuating shaft to thereby secure and fix the actuating shaft in position in the housing.Type: GrantFiled: October 14, 2008Date of Patent: August 27, 2013Assignee: EMKA Beschlagteile GmbH & Co.

Patent number: 7040672Abstract: A bolt lock, especially for control-cabinet doors or similar doors or flaps. The lock comprises a flat-bar bolt that is mounted to move parallel to the edge of the door, preferably within the arc of swing of the door. Disposed on the flat-bar bolt is at least one locking section. A bolt holder is mounted on the frame of the door to receive and hold the locking section. An actuator is provided for longitudinal displacement of the flat-bar bolt between an unlocked and a locked position. To provide a more secure lock that cannot become stuck, there is provided that to form the locking section, at least a portion of a length of the flat-bar bolt is twisted about a longitudinal axis of the bolt such that the twisted portion is disposed at an angle to an orientation of the bolt and provides a locking surface. The bolt holder is provided with a catch that is disposed at the same angle relative to the bolt as is the locking surface, with the catch being adapted to engage over the locking surface.Type: GrantFiled: March 30, 1993Date of Patent: May 9, 2006Assignee: EMKA Beschlagteile GmbH & Co.

Patent number: 6138484Abstract: A rod locking device for locking cabinet doors has locking rods movable between an unlocked position for unlocking the cabinet doors and a locking position for locking the cabinet doors. A two-part lock housing having short rods arranged therein is provided. The short rods are connected by a connecting device to the locking rods. The lock housing has a drive member arranged therein and connected to the short rods. An actuating device is connected to the drive member for actuating the drive member in order to move the short rods. The short rods have a length such that, in a retracted position, the short rods do not project from the lock housing. The lock housing has a base plate to be positioned at the exterior side of the cabinet door at a door penetration.Type: GrantFiled: April 8, 1999Date of Patent: October 31, 2000Assignee: EMKA Beschlagteile GmbH & Co.

Patent number: 5893282Abstract: A locking device for control cabinet doors has a plate with a depression attached to an outwardly facing side of a door leaf. The pivot lever is positioned in the depression. A projection is connected to a face of the plate facing the door leaf, the projection extending through a cutout of the door leaf past an inwardly facing side of the door leaf. A cap is connected to a free end of the projection, wherein the cap and the projection define a receiving chamber. A lock for locking the pivot lever when folded into the depression is provided. A housing matching the design and size of the lock is provided. The lock is enclosed and secured in the housing. The housing is exchangeably positioned in the receiving chamber. The plate has a receiving opening for providing access to the lock. The receiving opening has a periphery matching the shape of the housing.Type: GrantFiled: December 18, 1996Date of Patent: April 13, 1999Assignee: EMKA Beschlagteile GmbH & Co.

Patent number: 5519920Abstract: A hinge for holding two components, such as a cabinet and its door or the like, that are supported so as to pivotable relative to one another about the axis of the hinge. The hinge has a hinge support that is disposed on one of the components and has two aligned eyelets. A hinge bolt is connected to the other component and extends through the eyelets in order to connect the components. To be able to displace the components relative to one another, the hinge bolt is fixedly connected to its component and the eyelets are attached to the hinge bolt via pivotable connected rods such that the eyelets are displaceable along an axis of the hinge bolt, with the hinge bolt having such a configuration that rotation of the hinge bolt effects displacement of the eyelets.Type: GrantFiled: November 30, 1994Date of Patent: May 28, 1996Assignee: EMKA Beschalagteile GmbH & Co.
