Title: Rotating grip for a pneumatic tool

Description:
FIELD OF THE INVENTION 
     This invention is directed towards a sleeve secured to a portion of a barrel of an air hammer, air gun or similar pneumatic tool and process of using the hand tool. 
     BACKGROUND OF THE INVENTION 
     Pneumatic tools such as impact wrenches, socket wrenches, and similar tools are frequently used by automotive repair technicians. Frequently, the tool needs to be positioned and maneuvered into a preferred orientation or rapidly repositioned from one location to a second location during a repair job. Such positioning typically involves repositioning the tool relative to the user&#39;s support hand which is positioned about the barrel of the air tool. For extended use, the repetitive movement and placement of the air tool requires a frequent adjustment and rotation with respect to the operator&#39;s support hands. This can create both operator fatigue as well as contribute to a longer time interval of situating and resituating the tool. Within the context of a professional, frequent user of such tools, the constant manipulation of the tool and the tool orientation can create fatigue and be time consuming. Accordingly, there remains room for variation and improvement within the art. 
     SUMMARY OF THE INVENTION 
     It is one aspect of at least one of the present embodiments to provide for a cylindrical sleeve positioned on an exterior portion of a barrel of an air tool which allows rotation of the air tool relative to the sleeve. 
     It is a further object of at least one embodiment of the present invention to provide an air tool with a rotatable sleeve secured to a barrel of the air tool where the sleeve is cylindrical. 
     It is a further object of at least one embodiment of the present invention to provide an air tool with a rotatable sleeve secured to a barrel of the air tool where the sleeve is tapered. 
     It is a further object of a least one embodiment of the present invention to provide a new and improved air tool in which the air tool has a rotatable sleeve along an longitudinal axis of the air tool, the sleeve secured to the air tool by a retaining ring defined along a barrel of the air tool. 
     It is a further object of at least one embodiment of the present invention to provide for a sleeve on an air tool that is secured to a longitudinal portion of the air tool by a retaining ring in which the retaining ring provides for an effective amount of rotational resistance between the sleeve and the air tool. 
     These and other features, aspects, and advantages of the present invention will become better understood with reference to the following description and appended claims.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Reference will now be made in detail to the embodiments of the invention, one or more examples of which are set forth below. Each example is provided by way of explanation of the invention, not limitation of the invention. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used on another embodiment to yield a still further embodiment. Thus, it is intended that the present invention cover such modifications and variations as come within the scope of the appended claims and their equivalents. Other objects, features, and aspects of the present invention are disclosed in the following detailed description. It is to be understood by one of ordinary skill in the art that the present discussion is a description of exemplary embodiments only and is not intended as limiting the broader aspects of the present invention, which broader aspects are embodied in the exemplary constructions. 
     It is to be understood that the ranges mentioned herein include all ranges located within the prescribed range. As such, all ranges mentioned herein include all sub-ranges included in the mentioned ranges. For instance, a range from 100-200 also includes ranges from 110-150, 170-190, and 153-162. Further, all limits mentioned herein include all other limits included in the mentioned limits. For instance, a limit of up to 7 also includes a limit of up to 5, up to 3, and up to 4.5. 
     In describing the various figures herein, the same reference numbers are used throughout to describe the same material, apparatus, or process pathway. To avoid redundancy, detailed descriptions of much of the apparatus once described in relation to a figure is not repeated in the descriptions of subsequent figures, although such apparatus or process is labeled with the same reference numbers. 
     As set forth in  FIGS. 1-3 , a tool gun  10  is illustrated having a cylindrical barrel portion  20  ( FIG. 3 ) extending from the main body of the air tool surrounding the barrel  20  and exhaust deflector  50  is an exhaust deflector  50 . A rotatable sleeve  30  is secured along an exterior of barrel  20  and is designed to rotate via an attachment to a retaining ring  40 .  FIG. 1  illustrates one embodiment of the retaining ring  40  positioned on barrel  20  near a first end of the rotatable sleeve  30 . While the retaining ring  40  is illustrated positioned near one end of the sleeve  30 , other configurations are possible where the retaining ring is positioned along any suitable interior portion of sleeve  30 . 
     Preferably, the tension provided between the retaining ring  40  and sleeve  30  provides sufficient resistance to rotation such that a user can easily rotate the tool relative to the sleeve  30  but the resistance is sufficient enough to prevent the “free wheeling” or too low of a resistance force. 
     Alternatives to a retaining ring for the rotational arrangement between the sleeve and the barrel of the air tool are also possible including the use of a groove on the barrel which interacts with a mated projection defined by the sleeve. 
     One advantage of the rotatable sleeve  30  with respect to the air tool  10  is that it helps eliminate operator fatigue when using the tool for extended periods of time and or with repetitive motion. The rotating sleeve allows the operator to secure the hand tool and also move the main body of the tool in order to accommodate tight spaces within the tool environment. In addition, the rotating sleeve provides an additional margin of safety when using the air tool should an unexpected resistance or torque be experienced that might create an unexpected rotation of the barrel relative to the operator&#39;s hand. Absent the rotating sleeve, the tool could move suddenly within the operator&#39;s hand causing loss control of the tool or injury. With the rotating sleeve, the unexpected movement does not effect the securement of the tool when the collar is engaged by the operator. 
     As seen in  FIGS. 1-3 , one embodiment of the rotatating sleeve  30  is in the form of a cylinder and in which a longitudinal axis of the air tool barrel is aligned with a longitudinal axis of the sleeve. It is envisioned that other shapes of the sleeve can be provided including variations where the exterior of the sleeve may define a taper that facilitates gripping by the operator. In addition, the exterior of the sleeve can be textured or constructed of a cushioning material that provides a more comfortable grip. It is also envisioned that the rotatable sleeve can be in the form of an ergonomic grip that facilitates engagement by the operator&#39;s hand but still rotates relative to the barrel of the air tool. 
     As further seen in reference to  FIGS. 1-3 , the exhaust deflector  50  may be opposite an exterior surface of the barrel. When an exhaust deflector  50  is present, the sleeve  30  would be positioned directly opposite the corresponding portion of the deflector  50 . In some embodiments, the interior of the sleeve may physically engage one of a surface of either the barrel exterior or the deflector exterior. 
     Although preferred embodiments of the invention have been described using specific terms, devices, and methods, such description is for illustrative purposes only. The words used are words of description rather than of limitation. It is to be understood that changes and variations may be made by those of ordinary skill in the art without departing from the spirit or the scope of the present invention. In addition, it should be understood that aspects of the various embodiments may be interchanged, both in whole, or in part. Therefore, the spirit and scope of the invention should not be limited to the description of the preferred versions contained therein.
