20150306752 | PNEUMATIC NAIL GUN - A pneumatic nail gun includes a nail-gun main body, a first trigger, an auxiliary handle, an insurance unit, and an auxiliary insurance mechanism. The first trigger is disposed in the nail-gun main body. The auxiliary handle is extended from the nail-gun main body. The insurance unit is disposed at a nail outlet of the nail-gun main body and being capable of shifting between a non-firing location and a location to be fired. The auxiliary insurance mechanism includes a second trigger and an insurance stopper element. The second trigger is disposed on the auxiliary handle. The insurance stopper element is disposed in the nail-gun main body. The insurance stopper element is capable of shifting between a first location and a second location as controlled by operation of the second trigger so as to selectively block a shifting path of the insurance unit. | 10-29-2015 |
20150314432 | DRIVING TOOL - A driving tool, such as a nailer, includes a compression cylinder, a compression piston, an electric motor, a control apparatus, a trigger, a trigger switch, a driver guide, and a contact-arm switch. The control apparatus prevents fasteners, such as nails, from being driven when the controller identifies a state, in which it is likely that a malfunction or mis-operation of the driving tool is occurring. | 11-05-2015 |
20150336253 | Fastener Driving Apparatus - A fastener driving apparatus includes an extensible polymer assembly and a fastener drive assembly, such that when said extensible polymer assembly is actuated (by a motor and linear motion converter), energy is stored as an extensible polymer of the polymer assembly extends in length and force from said extensible polymer is applied on said fastener drive assembly. When said extensible polymer reaches a sufficient extension, a retention means releases said fastener drive assembly and wherein said fastener drive assembly moves from a first position to a second position such that an anvil of the fastener drive assembly is capable of driving a fastener into a substrate. | 11-26-2015 |
