A reset lever is mounted for movement between open and closed positions. The trigger disconnector assembly is in mechanical communication with the reset lever. A striking end of the hammer strikes the reset lever in a past-cocked position of the hammer moving the reset lever from the open position to the closed position, the reset lever acting on the trigger disconnector assembly to reset the trigger body and the disconnector in the past-cocked position of the hammer in preparation for securing the hammer in a cocked position preparatory to firing by another trigger pull of the trigger body. | 12-18-2014 |
| 20140373418 | FIREARM FIRING SYSTEM - A firearm firing mechanism is so configured that a hammer is retaining by a front retaining block before pressing a trigger; pressing the trigger slightly at a first stage causes a main bar to bias a rear retaining block and the front retaining block backwardly at a relatively smaller angle to release the hammer in performing a single-shot action; pressing the trigger heavily at a second stage causes the main bar at a relatively longer distance so that the hammer is kept away from the front retaining block when it is returned, and the hammer is secured by the rear retaining block upon a backward displacement of a bolt and backward biasing of the hammer, and a linkage is forced to move the rear retaining block in releasing the hammer for firing when the bolt forward again, and a continuous multi-shot firing action is performed by means of repeating this operation. Thus, the invention enhances the operation convenience in achieving single-shot and multi-shot firing actions. | 12-25-2014 |
| 20160018176 | TRIGGER GROUP FOR SEMI-AUTOMATIC FIREARMS - Trigger groups for semi-automatic firearms have a hammer, a trigger element, a sear, a selector, and a disconnector assembly, the disconnector assembly operable when the selector is in a first position to retain the hammer in the cocked position in response to release of the trigger element to the rest position subsequent to discharge of the firearm by pulling the trigger element, and the disconnector assembly operable when the selector is in a second position to release the hammer to the striking position in response to release of the trigger element to the rest position subsequent to discharge of the firearm by pulling the trigger element, such that the firearm discharges once per cycle of the trigger element when the selector is in the first position, and fires once for each forward or rearward motion of the trigger element when the selector is in the second position. | 01-21-2016 |
