Patent number: 8677883Abstract: Rotary lug breeches and weapons including such rotary lug breeches are disclosed. An example rotary lug breech includes a bolt carrier. Wherein when releasing the bolt, a cam section of a receiver converts a releasing motion into a screwing motion to release a cartridge. During the screwing motion, a first stud surface interacts with the cam section. During a locking process, the first stud surface engages the cam section to perform a pre-control process that rotates a control pin in a slot from a releasing position in which an advancement of the bolt carrier exerts substantially no torque on the bolt, to a control position in which a first slot surface of the slot interacts with the control pin. When the bolt carrier moves forward, the bolt carrier exerts a torque on the bolt to enable the bolt and the bolt carrier move relative to one another.Type: GrantFiled: August 24, 2012Date of Patent: March 25, 2014Assignee: Heckler & Koch GmbHInventors: Ernst Wössner, Stefan Doll, Martin Stussak

Patent number: 8584574Abstract: Weapons, weapon housing and methods of producing such weapons and weapon housings are disclosed. An example weapon housing for use with a firearm includes at least two housing shells. Each of the housing shells comprises at least one positioning recess. The example weapon housing also includes at least one connection block comprising connecting pins. On an assembly plane of the connection block, the housing shells are to be positioned and aligned on the connecting pins via the respective positioning recess to enable forces that are to act in or against a direction of fire to be absorbed by surfaces of at least one of the positioning recesses or one or more of the connecting pins.Type: GrantFiled: January 23, 2012Date of Patent: November 19, 2013Assignee: Heckler & Koch GmbHInventors: Ernst Wössner, Stefan Doll

Patent number: 8117779Abstract: Catches and trigger apparatus for use with weapons are described. An example trigger apparatus for use with a firearm having a breech includes a latch moveable between a blocking position that blocks the breech and a non-blocking position that does not block the breech. The latch includes a sear arm, a spring assembly, and a securing element moveable between a first position and a second position. The spring assembly is to bias the securing element. In the first position, the securing element is positioned at a distance from the sear arm and a surface of a securing device in a securing position to enable the latch to be moved to the non-blocking position and the breech to retract relative to the weapon. In the second position, the securing element is positioned adjacent the sear arm via the breech and the surface of the securing device in the securing position to secure the latch in the blocking position.Type: GrantFiled: April 30, 2010Date of Patent: February 21, 2012Assignee: Heckler & Koch GmbHInventors: Stefan Doll, Ernst Wössner

Patent number: 7802511Abstract: Described herein are examples of firearms and firearm assemblies. In one example, a firearm assembly for use in a firearm including a breech block, includes safety equipment; a slide stop, wherein the slide stop is adjustable between an arresting position that locks the breech block and a position that does not lock the breech block; and a safety element adjustable relative to the slide stop between a neutral position and secured position, wherein in the secured position if the breech block exerts an operating force on the safety element and the safety element engages the safety equipment, the safety element fixes the slide stop in its arresting position.Type: GrantFiled: August 22, 2008Date of Patent: September 28, 2010Assignee: Heckler & Koch, GmbHInventors: Stefan Doll, Ernst Wössner

Patent number: 7721639Abstract: Methods and apparatus are disclosed for a locked machine gun that includes a casing, a barrel, a locking breech mechanism, an abutment and a quick change attachment. The locking breech mechanism has at least one locking body. The abutment holds the locking body or locking bodies of the locked breech mechanism. The quick-change attachment is used to facilitate the removal of the barrel and insertion and attachment of a new barrel. A first part of the abutment remains on the casing when the barrel is being changed, and a second part of the abutment is firmly connected to the barrel. The quick-change attachment is equipped to bring about a separation between the first part of the abutment remaining with the casing and the barrel with the second part. Also, the second part of the abutment has a curved section which controls the engagement of the breech mechanism in the abutment when the breech mechanism closes.Type: GrantFiled: January 3, 2005Date of Patent: May 25, 2010Assignee: Heckler & Koch GmbHInventor: Ernst Wössner

Patent number: 7658138Abstract: Practice barrels for use with practice cartridges are described herein. An example practice device for use with self-loading grenade launchers includes a practice barrel having a practice cartridge chamber to receive a practice cartridge. A live cartridge does not correspond to the practice cartridge chamber. Additionally, the live cartridge is unable to be properly positioned within the practice barrel to prevent ignition of the live cartridge. Further, the practice cartridge chamber is cushioned to substantially absorb a breech energy to substantially prevent damage to the practice barrel.Type: GrantFiled: October 22, 2008Date of Patent: February 9, 2010Assignee: Heckler & Koch GmbHInventors: Ernst Wössner, Rudi Beckmann
