BACKGROUND OF THE INVENTIONPower tools, and particularly pneumatic power tools, typically include a metal housing that has a handle. A hose is connected to the power tool in the vicinity of the handle. Alternatively, with battery operated tools, a battery pack is installed on the power tool. Oftentimes, power packs are also installed in the vicinity of the handle. Power tools may be powered in a number of different manners, including combustion, electric, powder-activated, pneumatic, battery, and otherwise as known in the art.
When not in use, users of power tools often prefer to hang the tool from a belt or on other objects, such as ladders, scaffolding or the like at a job site. Power tools are often used in tight spaces. Therefore, shape and size is important to the overall power tool design.
Nail guns are utilized to drive nails or staples into surfaces. They typically utilize a separate magazine portion for storing a stick of nails or staples prior to nailing to a surface. The magazine is attached between respective ends of the main housing and the handle of the nail gun. Magazines on small nailers or staplers typically hold a single stick of nails. Additional sticks of nails are usually stored in a box and the user must either lug the box around during use of the nailer, or must return to the location of the box when the nailer magazine is empty.

The first leg of the L 38 is cylindrical along parts of its length. The attachment end 34 includes an inner ledge 42 that is configured to rest against the side 26, 28 of the back leg 22. The inner ledge 42 has a dimension that is greater than the dimension of the opening 32 in the back leg 22 so that it serves as a stop against the side 26, 28 of the tool 10.
The attachment end 34 includes a middle portion 44 that is configured to seat inside the opening 32 of the back leg 22. The middle portion 44 is cylindrical and includes a cut out 46 that forms a spring arm 48. The spring arm 48 is resilient and can bend inwardly and spring outwardly with the application of force. The spring arm 48 has a spring arm free end 50 that includes an outwardly extending knob 52. The knob 52 is sized to mate with a notch 54 defined inside the opening 32 in the back leg 22 of the nailer 10. The notch 54 is positioned inside the opening 32 so that the belt hook 30 can only be positioned in a single desired position, which is obtained upon rotation of the hook 30 into the proper position. The spring arm 48 together with the notch 54 provide a spring loaded detent for positioning the belt hook 30 in a specific position relative to the tool 10.
The attachment end 34 also includes an outer stop member 56 that has a shape and size configured to fit through the opening 32 in the back leg 22. The stop member 56 has outwardly extending legs 58 so that after the attachment end 34 is inserted through the opening 32 and the inner ledge 42 abuts the side 26, 28 of the back leg 22, the belt hook 30 can be turned so that the outwardly extending legs 58 abut the opposite side of the back leg 22 to hold the belt hook 30 in position. In a preferred embodiment, where an oval opening is provided in the back leg 22, the inner ledge 42 is circular, the middle portion 44 is cylindrical, and the outer stop member 56 is oval or oblong in cross-section. Other shapes and sizes for the opening 32 and the attachment end 34 may also be utilized. For example, a rectangular opening and a rectangular attachment end may be used, where the stop member 56 is rectangular. In this instance, the inner ledge and middle portion may remain cylindrical, or can take on another desired shape.
The second leg of the L 40 is preferably flat and smooth and may include a bend 60. The bend 60 is utilized to restrain the belt hook 30 on a belt or other surface and to make it easier to place or remove the belt hook 30 from a belt or other surface.
Referring to
The belt hook 30 is preferably made of a plastic material, such as nylon. Other types of materials may also be used, as long as they have sufficient strength to hold a power tool.
In a preferred embodiment, the first leg 38 has a length of about 1½ inches for the portion of the leg that extends outwardly from the tool and the second leg 40 has a length of about 2½ inches. Other dimensions for the belt hook 30 may also be utilized, as desired. It is preferred that the first leg 38 have a length sufficient so that the belt hook 30 extends past the outermost side of the tool 10. Thus, leg length will be dependent on the size of the power tool. In addition, there may be instances where it is desirable to have a leg length so that the belt hook 30 does not extend past the outermost side of the tool. The present invention incorporates this length as well.
