DETAILED DESCRIPTION

A screwdriver 10 includes a handle 14, a shank 18, and a neck 22 in between the handle 14 and the shank 18. In some embodiments, the neck 22 is omitted from the screwdriver 10. The shank 18 includes a hex bolster 26, such that a wrench may be used to manipulate and rotate the screwdriver 10 via the hex bolster 26. Knurling 30 is provided on a portion of the shank 18 and a tip 34 is provided on the end of the shank 18 opposite the handle.

The handle 14 may be made of multiple materials. In the illustrated embodiment, the handle has a core plastic material 38, which also forms neck 22. As shown in FIG. 16, the shank 18 is formed from metal and to assembly the screwdriver 10, a rear portion 40 of the shank 18 is set into an annular bore 44 that begins at the neck 22 and is longitudinally defined within the core plastic material 38. In alternative embodiments, the bore 44 is omitted and the shank 18 is simply insert molded into the core plastic material 38. As shown in FIG. 17, two grooves 48 arranged opposite each other extend radially outward from the annular profile of the bore 44 along at least a portion of the length of the bore 44. As shown in FIG. 18, two splines 52 extend radially outward from the rear portion 40 of the shank 18. The splines 52 are arranged within the grooves 48 when the rear portion of the shank 40 is arranged within the bore 44. A hard plastic material 42 is provided around the core plastic material 38 and a rubber overmold material 46 is provided over the hard plastic material 42. A recess 50 is defined in the handle 14 for attachment to a lanyard or a tool belt. In the illustrated embodiment, the recess 50 extends through the hard plastic material 42 and the core plastic material 38.

On the side of the handle 14 opposite the shank 18 the handle 14 has a butt 54. The butt 54 includes a first indicating element 58 having a shape corresponding to the tip 34. For instance, as shown in FIGS. 1 and 2, the first indicating element 58 has the shape of a cross. The cross shape corresponds to the tip 34 because the screwdriver 10 of FIGS. 1-3 is a Philips head screwdriver, and thus has a cross-shaped tip 34, as shown in FIG. 3. As shown in FIGS. 1 and 2, the butt 54 also includes a plurality of second indicating elements 62 arranged around the first indicating element 58. Also, in the illustrated embodiment, the second indicating elements 62 are arranged around the first indicating element 58 in an annular arrangement. However, in other embodiments, the second indicating elements 62 could be arranged around the first indicating element 58 in other arrangements or patterns, such as polygonal arrangements.

The second indicating elements 62 have the same shape as the first indicating element 58. In the illustrated embodiment, the first indicating element 58 has a first size that is slightly larger than a second size of the second indicating elements 62. However, in other embodiments, the first indicating element 58 may be the same size as the second indicating elements 62. In the illustrated embodiment, the first indicating element 58 is located on the core plastic material 38 portion of the butt 54 and the second indicating elements 62 are located on the hard plastic material 42 portion of the butt 54. However, in other embodiments, the first indicating element 58 and the second indicating elements 62 may be located on the same material portion of the butt 54.

In the illustrated embodiment, the first indicating element 58 is recessed into the butt 54 and the second indicating elements 62 are also recessed into the butt 54. However, in other embodiments, the first indicating element 58 may be a protrusion formed on the butt and the second indicating elements 62 may also be protrusions formed on the butt 54. In still other embodiments, the first indicating element 58 may be a protrusion and the second indicating elements 62 recessed, or the first indicating element 58 may be recessed and the second indicating elements 62 may be protrusions.

As shown in FIGS. 4-6, a square screwdriver 10 is illustrated. The square drive screwdriver 10 is identical to the Phillips head screwdriver 10 of FIGS. 1-3 except that the tip 34, first indicating element 58, and plurality of second indicating elements 62 have a square shape, rather than a cross shape. FIG. 7 illustrates the butt 54 of another square screwdriver, except that that the first indicating element 58 is larger than the first indicating element 58 of the square screwdriver butt 54 in FIG. 5, to indicate to the operator that the screwdriver 10 of FIG. 7 has a larger square tip 34 than the screwdriver 10 of FIGS. 4-6.

FIGS. 8 and 9 illustrate the butts 54 of two other screwdrivers 10 with first indicating elements 58 that have a shape corresponds to the tip 34 with the shape shown in FIG. 10. FIGS. 11 and 12 illustrate the butts 54 of two Pozidriv screwdrivers 10 with first indicating elements 58 that have a shape relating to the tip 34 shown in FIG. 13. FIG. 14 illustrates the butt 54 of a flathead screwdriver 10 with a first indicating element 58 having a shape relating to the tip 34 shown in FIG. 15. In the screwdriver 10 of FIGS. 14 and 15, instead of a plurality of second indicating elements 62, there is an annular recess 66 surrounding the first indicating element 58 on the butt 54.

Regardless of what size, shape, or pattern the first and second indicating elements 58, 62 are arranged in, and regardless of whether the first and second indicating elements 58, 62 are recessed or formed as protrusions on the butt 54, the first and second indicating elements 58, 62 are tactile indications for the operator representing the type of screwdriver IO being utilized. An operator need only reach down and feel the butt 54 of the screwdriver TO, by pressing fingers against the first and/or second indicating elements 58, 62, to identify the type of screwdriver 10 and the tip 34 it utilizes.

Various features of the invention are set forth in the following claims.
