Air powered wrench device with pivotable head and method of using

[0001] The present invention relates hand tools, more particularly, to an air powered wrench device with a pivotable head and a associated method of using the device.

[0002] Wrenches having a straight fixed head are difficult to use in tight spaces which are often readily accessible by wrenches having a head located at an angled position relative to a body of the wrench. Many currently available wrenches that have an adjustable head typically require the head to be moved away from the body to adjust the position of the head relative to the body. This is inconvenient since it generally requires two hands to adjust the head and requires the wrench to be moved away from the fastener the wrench is being used to loosen or tighten.

[0003] A separate but related problem, particularly associated with power wrenches is the transmission of power through a pivot point. A power wrench currently available with an adjustable head has a continuous flexible drive shaft extending from the body to the head. Since the shaft is subject to constant bending, the shaft is susceptible to fatigue over a period of time. The pivot connection of the head of the wrench to its body is structurally separate from the drive shaft, as is the mechanism for locking the head in a selected angular position relative to the body. Thus the wrench has several different parts required for pivoting, adding to the complexity and weight of the wrench.

[0004] A wide variety of wrench devices is currently available on the commercial market and an even larger number of these types of devices are known in the art of wrench devices, for example, the power driven replacement socket ratchet wrench disclosed by Anderson et al. in U.S. Pat. No. 4,993,288; the ratchet drive tool with manual and non-manual power actuation disclosed by Evans in U.S. Pat. No. 5,251,706; the ratchet wrench with pivotable head disclosed by Izumisawa in U.S. Pat. No. 5,784,934; the angularly adjustable powered surgical handpiece disclosed by Fox et al. in U.S. Pat. No. 6,050,989; the ratchet wrench with pivotable head disclosed by Izumisawa in U.S. Pat. No. 6,311,583; and the pneumatic hand tool disclosed by Izumisawa in U.S. Pat. No. D408,243.

[0005] While all of the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a wrench device having a a handle pivotally attached to an arm in which the handle comprises a housing, an air intake nozzle, an air driven motor, a drive shaft, a ball bearing collar, a universal joint, an on/off button, a trigger switch, a directional throw switch, a lock pin, a spring, and a pivot post and the arm includes: an outer casing an extension rod, a ball bearing sleeve, a first pawl gear, a second pawl gear, and a bit connector. This combination of elements would specifically match the user's particular individual needs of making it possible to perform the operational steps of adjoining, affixing, aligning, allowing, enshrouding, getting, moving, obtaining, putting, rotating, shifting, squeezing, and tightening. The above-described patents make no provision for a wrench device having a handle pivotally attached to an arm in which the handle comprises a housing, an air intake nozzle, an air driven motor, a drive shaft, a ball bearing collar, a universal joint, an on/off button, a trigger switch, a directional throw switch, a lock pin, a spring, and a pivot post and the arm includes: an outer casing an extension rod, a ball bearing sleeve, a first pawl gear, a second pawl gear, and a bit connector.

In this respect, the wrench device according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of providing a means for adjoining, affixing, aligning, allowing, enshrouding, getting, moving, obtaining, putting, rotating, shifting, squeezing, and tightening.

[0007] The present device and method of using, according to the principles of the present invention, overcomes the shortcomings of the prior art by providing a wrench device and associated method of using are disclosed. The device comprises a handle pivotally attached to an arm. The handle comprises a housing, an air intake nozzle, an air driven motor, a drive shaft, a ball bearing collar, a universal joint, an on/off button, a trigger switch, a directional throw switch, a lock pin, a spring, and a pivot post. The arm is pivotally attached to the handle via the pivot post. The arm includes: an outer casing, an extension rod, a ball bearing sleeve, a first pawl gear, a second pawl gear, and a bit connector. The method of using the device comprises the steps of adjoining, affixing, aligning, allowing, enshrouding, getting, moving, obtaining, putting, rotating, shifting, squeezing, and tightening.

[0008] In view of the foregoing disadvantages inherent in the known type wrench devices now present in the prior art, the present invention provides an improved wrench device, which will be described subsequently in great detail, is to provide a new and improved wrench device which is not anticipated, rendered obvious, suggested, or even implied by the prior art, either alone or in any combination thereof.
