The following includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art nor material to the presently described or claimed inventions, nor that any publication or document that is specifically or implicitly referenced is prior art.
The present invention relates generally to the field of tools of existing art and more specifically relates to a tool driving by impact delivering component or cooperating anvil.
Many people work on construction projects. When framing and roofing houses and barns or doing any other construction work, it can be time-consuming and laborious to manually drive screws into place. Many people end up needing frequent breaks or, even worse, hurting their hands, which causes an increase in downtime on jobsites and can potentially throw off an entire construction timeline. Instead, some workers may use a traditional screw gun, but they often lack efficiency and power. A suitable solution is desired.
U.S. Pub. No. 2010/0064,864 to Shigeki Kobayashi relates to a double hammer clutch impact tool. The described double hammer clutch impact tool is a power driven tool for rotating a mechanical fastener including a housing with a motor positioned in the housing. The motor includes a drive shaft that rotates relative to the housing. An impact mechanism in the housing is operatively connected to the motor drive shaft. The impact mechanism has a base, an output and a cam. The output and cam are rotatably mounted on the base. A pair of hammers are pivotally mounted on the base and selectively positioned by the cam. The cam biases the hammers to intermittently impact the output. A ratchet head assembly is operatively connected to the output of the impact mechanism. The ratchet head assembly includes an output member rotatably mounted on the housing to rotate the mechanical fastener. The assembly also includes a ratchet operable to limit rotation of the output member in a selected direction.
In view of the foregoing disadvantages inherent in the known tool art, the present disclosure provides a novel air impact screw gun tool (system). The general purpose of the present disclosure, which will be described subsequently in greater detail, is to provide a reliable and efficient means to screw threaded fasteners.
The present invention uses an air compressor to drive screws into place for maximum impact, especially when framing and roofing houses and barns. The device alleviates some of the manual labor, reducing stress and strain on the body. It saves construction workers, contractors, and do-it-yourselfers a considerable amount of time and frustration. The device is lightweight and reduces the chance of injury, particularly to the hands. The device can provide up to 550 ft lbs of torque. The present invention helps keep workers on schedule, which helps keep clients happy which is desirable.
