|20130153254||DYNAMIC CLUTCH APPARATUS FOR ELECTRICAL NAIL GUN - A dynamic clutch apparatus for an electrical nail gun is disclosed and includes a pair of symmetric direct stroke apertures formed on a gun body support; a firing pin set slidably installed on a side of the gun body support; a guiding base movably installed inside the gun body support; a pair of symmetric oblique stroke apertures formed on the guiding base. Aperture walls of the oblique and direct stroke apertures encircle and form an interconnected through aperture. Two pivot bearings are slidably installed inside the through aperture. A flywheel for accumulating kinetic energy is installed between the pivot bearings coaxially. An electromagnetic driver drives the guiding base to move, causing the through aperture to restrict the pivot bearings and the flywheel to move and press the firing pin set. Then, the firing pin set passes nail-percussion kinetic energy along a nail-percussion axial direction.||06-20-2013|
|20120187175||Locking Mechanism of Nail Gun - A locking mechanism for a nail gun includes a side slot formed on a bottom side of a gun body and a nail supplying slot connected to a drive track of the nail gun. A stopper element is formed on a side of a slider element corresponding to the side slot. The gun also includes a magazine in which a nail pusher facing the nail supplying slot and a lockout element facing the side slot are formed. The nail pusher has an ear portion. The lockout element includes a pushing arm and a moveable guide slot capping with the ear portion to restrict the sliding movement of the lockout element on the nail pusher. As the pushing arm extends towards the corresponding end of the nail supplying slot, a nail is pushed into the drive track to shoot. The lockout element enters into the side slot to block the stopper element when the nail is exhausted, so as to enhance the shooting blocking effect of the nail gun.||07-26-2012|
|20110290850||PNEUMATIC DEVICE - An improved pneumatic device includes a body having a hollow cavity, defining an X axis and having a first end and a second end. The body includes a movable cylinder, a nail-firing piston rod and at least one exhaust hole. The movable cylinder and the nail-firing piston rod reciprocate along the X axis in the body by performing a forward stroke to the second end, and a return stroke back to the first end. The movable cylinder presents an open status when completing the forward stroke and presents a closed status when completing the return stroke. The movable cylinder has an exhaust hole and an exhaust valve disposed at an outer periphery thereof. When the nail-firing piston rod has not completed the return stroke yet and the cylinder is in the closed status, an exhaust channel is thereby formed to facilitate exhausting of air.||12-01-2011|
|20110278342||NAIL GUN WITH IMPROVED ATTACHABLE AND DETACHABLE MAGAZINE ASSEMBLY - The present invention relates to a nail gun with an improved attachable and detachable magazine assembly, comprising: a nail gun, a magazine assembly and an attach and detach mechanism. A handle portion of the nail gun has a joining pillar capable of joining with the attach and detach mechanism for attaching the magazine assembly with the nail gun, wherein the attach and detach mechanism further comprises: a fixing frame, a swinging fastening bar, a fastening member, and an elastic element. When it is desired to attach the joining pillar with the magazine assembly, the swinging fastening bar must be swung out firstly, so as to insert the joining pillar into the fixing frame, and continuously, to swing the swinging fastening bar close to the fixing frame, furthermore, then the fastening notch is able to grip and fix the joining pillar inside the fixing frame, finally, the joining pillar is completely attached with the magazine assembly.||11-17-2011|
|20110215131||NAIL GUN WITH RAPIDLY ATTACHABLE AND DETACHABLE MAGAZINE ASSEMBLY - A nail gun with a rapidly attachable and detachable magazine assembly includes a nail gun, a magazine assembly and a quick joining mechanism. A handle portion of the nail gun has a quick joining pillar adapted to engage with the quick joining mechanism to attach the magazine assembly to the nail gun. By simply snap-fitting the quick joining pillar into a fixing element of the quick joining mechanism, the quick joining mechanism can naturally fix the quick joining pillar into the fixing element, and thus, the magazine assembly can be attached to the nail gun by simply a single action. Moreover, by pulling a pull rod of the quick joining mechanism and withdrawing the quick joining pillar from within the fixing element, the magazine assembly can be attached from the nail gun by also simply a single action.||09-08-2011|
|20110132959||FASTENER DRIVER WITH AN OPERATING SWITCH - A fastening tool includes a drive assembly configured to drive a fastener from the fastening tool, a work contact element moveable between an extended position and a depressed position, a trigger moveable between a release position and a fire position, an electric power source, an electronic control unit configured to deliver electric power from the electric power source to the drive assembly, and a single electric switch connected to the electronic control unit and configured to indicate that the work contact element is in the depressed position and the trigger is in the fire position.||06-09-2011|
|20110132958||FASTENING TOOL WITH RELEASABLE WORK CONTACT ELEMENT - A tool for driving fasteners includes a work contact element configured to move between a first position and a second position. The tool is prevented from driving fasteners when the work contact element is in the first position. The tool further includes an extension member rigidly connected to the work contact element in a releasable connection arrangement. The releasable connection arrangement is configured to maintain a rigid connection between the work contact element and the extension member during normal operation of the tool. The releasable connection arrangement is further configured to release the rigid connection between the work contact element and the extension member during high impact events that are not associated with normal operation of the tool.||06-09-2011|
|20110062208||FASTENER DRIVER WITH DRIVER ASSEMBLY BLOCKING MEMBER - A device for driving a plurality of fasteners includes a driver assembly having a drive block, a flywheel and a driver mount. The driver mount is configured to move between a first position where the flywheel is removed from the drive block and a second position where the flywheel engages the drive block. The device also includes a work contact element configured to move between an extended position and a depressed position. A blocking arm is connected to the work contact element and configured to move with the work contact element. The blocking arm is positioned in a path of movement of the driver mount when the work contact element is in the extended position. The blocking arm is removed from the path of movement of the driver mount when the Work contact element is in the depressed position.||03-17-2011|
|20100213234||NAILER STRIKE PLATE - A device for impacting a fastener in one embodiment includes a housing with an upper housing portion, a middle housing portion, and a side housing portion extending between the upper housing portion and the middle housing portion, a drive cylinder configured to vent within the housing, an air passage extending through the housing and including a mouth at the upper housing portion, and a strike plate extending over the upper housing portion and including a top portion positioned apart from the upper housing portion, and a first side extension extending downwardly from the top portion along the side housing portion to a location above and spaced apart from an outwardly extending first surface of the middle housing portion.||08-26-2010|
