Description




FIELD OF THE INVENTION




The present invention relates to a tool with a fastener engaging member, and in particular, to a fastener engaging member that forms an interface with at least one surface on the fastener such that the fastener is releasably retained to the driving portion of the tool.




BACKGROUND OF THE INVENTION




The prior art has long sought to develop a satisfactory holding attachment for tools that assist the user in holding, piloting and starting a fastener, as well as with the removal of the fastener. One approach is to magnetize the tool. A magnetized tool is only suitable for retaining ferrous fasteners. Magnetized tools also collect ferrous debris, such as metal shavings and chips.




U.S. Pat. No. 1,698,521 (Wood); U.S. Pat. No. 1,712,196 (Burger et al.); and U.S. Pat. No. 3,245,446 (Morifuji) disclose a pair of inwardly biased members that grasp the head of the fastener. These devices can typically be used only on fastener with heads within a certain size range. If the fastener head is larger or smaller than that certain size range, the device does not operate as intended. For some of these devices, the shape of the head is also critical to proper operation.




U.S. Pat. No. 4,016,913 (Anderson) discloses a pair of springs extending between a pair of arms attached to the tool that are adapted to grip the shank or threaded portion of the fastener. The usefulness of the device of Anderson is also limited by the size of the fastener. For large diameter fasteners, longer springs are required. The longer springs, however, are less effective at holding smaller diameter fasteners. Consequently, multiple devices are required to accommodate fasteners with largely varying diameters.




U.S. Pat. No. 4,197,886 (MacDonald) discloses a fastener holding nosepiece for a driving tool. The nosepieces is removable from the adapter by a quick disconnect feature that permits. Different nosepieces are required to accommodate fasteners having heads of larger or smaller diameters.




BRIEF SUMMARY OF THE INVENTION




The present invention is directed to a tool adapted to releasably retain a fastener. The tool includes a driving portion comprising a plurality of tool surfaces adapted to form an interface with a fastener. At least one polymeric fastener engaging member is attached to the driving portion that extends above one or more of the tool surfaces. The fastener engaging member forms an interface with at least one surface on the fastener such that the fastener is releasably retained to the driving portion.




The present invention is also directed to a driving portion comprising a plurality of tool surfaces adapted to be positioned in the tool receiving recess. The fastener engaging member forms an interface with at least one surface in the tool receiving recess such that the fastener is releasably retained to the driving portion. The present invention is also directed to a tool with a fastener engaging member that is adapted to be positioned around a portion of the fastener.




In one embodiment, the fastener engaging member is attached to the driving portion at only one of the tool surfaces. In another embodiment, the fastener engaging member is attached to the driving portion along an edge between two adjacent tool surfaces.




The fastener engaging member can optionally be located in a hole formed in the driving portion. In one embodiment, the fastener engaging member is molded in a hole formed in the driving portion. The hole can be located in one of the tooling surfaces or along an edge between two adjacent tool surfaces. In one embodiment, the hole extends through the driving portion such that the fastener engaging member is located in the hole and extends above two non-adjacent tool surfaces on the driving portion. The two non-adjacent tooling surfaces are preferably opposing surfaces such that the compressive forces on the fastener engaging member are generally opposing and co-linear.




In one embodiment, a reinforcing member is located in the polymeric material. The reinforcing member can be a resilient member that deforms elastically, such as spring member or a wire, or a substantially rigid member. The reinforcing member typically extends above one or more of the tool surfaces of the driving portion. In one embodiment, the reinforcing member extends above the polymeric material. The reinforcing member can also be rigid. In this embodiment, the rigid reinforcing member would be displaced (typically rotated) during compression of the polymeric material.




The polymeric material is selected from a group comprising nylon, polypropylene, PVC, ABS, cellulose, acetyl, polyethylene, fluoropolymers, polycarbonate, natural or synthetic rubber, and the like. In one embodiment, the polymeric material comprises an adhesive. The polymeric material typically extends above the tool surface about 0.001 inches to about 0.2 inches, although this distance will vary considerably with the application, such as the type of tool, the type of fastener, the material from which the fastener is constructed, and the like. The tool can be one of a ballpoint tool, a torx® driver, square drivers, a hex wrench, socket wrench, a flat-head screw driver, a phillips screw driver, an open-ended wrench, a box wrench, or any other tool adapted to releasably engage with a fastener.




The present invention is also directed to a tool adapted for use with a fastener having a tool receiving recess. The tool includes a driving portion comprising a plurality of tool surfaces adapted to be positioned in the tool receiving recess. A hole located in the driving portion extends across two or less tool surfaces. At least one elongated fastener engaging member is located in the hole in the driving portion and extends above one or more of the tool surfaces. The fastener engaging member forms an interface with at least one surface in the tool receiving recess such that the fastener is releasably retained to the driving portion.




The fastener engaging member can be a polymeric material, metal, ceramic, or a combination thereof. The fastener engaging member can be configured as a coil spring, a wire, a ribbon, and the like. The fastener engaging member preferably comprises a spring member shaped to generate a biasing force against inside surfaces of the hole where the biasing force retains the elongated fastener engaging member in the hole. A polymeric material, such as an adhesive, can optionally be deposited in the hole with the elongated fastener engaging member.

DETAILED DESCRIPTION OF INVENTION





FIGS. 1



a


-


1




c


illustrate various views of a tool


20


in accordance with the present invention. In the illustrated embodiment, the tool


20


is a hex wrench with a standard hex-shaped driving portion


22


at one end and a ballpoint driving portion


24


at the other end. The ballpoint driving portion


24


can be a conventional ballpoint tool or a torx® driver, such as disclosed in U.S. Pat. No. 5,251,521.




The driving portion


22


includes six tool surfaces


26


(only three of which are shown) that are adapted to form an interface with a fastener (see FIG.


2


). In the illustrated embodiment, the driving portion


22


includes at least one polymeric fastener engaging member


28


. The fastener engaging member


28


is sufficiently elongated to extend above the tooling surfaces


26


to releasably retain a fastener to the driving portion


22


.




Each fastener engaging member


28


is preferably a discrete structure that is located in only one tool surface


26


or at a transition or edge between two adjacent tool surfaces


26


. As discussed herein, a plurality of fastener engaging members can be located at a plurality of locations on a single driving portion of a tool. As used herein, “discrete fastener engaging member” refers to a structure located on only one tool surface or at a transition or edge between two adjacent tool surfaces.




The driving portion


24


also includes six tool surfaces


32


. In the illustrated embodiment, a pair of opposing fastener engaging members


56


,


58


are located on opposite surfaces


32


of the driving portion


24


. The number and location of the fastener engaging members


56


,


58


can vary with the application. For example, the fastener engaging members


56


,


58


can be located on adjacent surfaces


32


. The fastener engaging members


56


,


58


each extend above their respective tooling surfaces


32


to releasably retain a fastener to the driving portion


24


(see FIG.


3


).





FIG. 2

is a side sectional view of the tool


20


of

FIGS. 1



a


-

c


engaged with a fastener


34


. The fastener


34


includes a tool receiving recess


36


having a plurality of inside surfaces


38


. In the illustrated embodiment, the tool receiving recess


36


includes six surfaces that correspond generally to the six tool surfaces


26


on the driving portion


22


. As used herein, “driving portion” refers to a portion of tool surfaces that engage or mate with a fastener. The amount of torque that is transmitted by a particular portion of a tool surface will vary with the design of the tool and the fastener. For example, there are portions of tool surfaces that mates with a fastener, but transmit little or no torque to the fastener.




The driving portion


22


of the tool


20


forms an interface


40


with the tool receiving recess


36


of the fastener


34


. As used herein, “interface” refers to point or surface contact between a fastener engaging member, a driving portion of a tool and a fastener. In the embodiment illustrated in

FIG. 2

, the interface


40


includes tooling surfaces


26


and the fastener engaging member


28


in contact with inside surfaces


38


on the fastener.




In order to permit engagement and disengagement with the fastener


34


, the driving portion


22


has a smaller cross-section than the tool receiving recess


36


. Gap


42


exists between the driving portion


22


and the inside surfaces


38


of the fastener


34


. The size of the gap


42


varies with the type of tool and the type of fastener. The gap


42


also varies around the perimeter of the driving portion


22


. For example, the gap


42


is generally greater at the tool surface


26


where the fastener engaging member


28


is located than at other tool surfaces


26


.




For low cost fasteners produced at high volume, the gap


42


is typically large enough that the fastener


34


will easily fall off the driving portion


22


. The polymeric fastener engaging member


28


is located at the interface


40


to engage with one or more of the inside surfaces


38


on the fastener


34


. Once engaged, the fastener engaging member


28


and tool surfaces


26


form a friction fit with one or more inside surfaces


38


of the fastener


34


. The fastener engaging member


28


is preferably elastically deformable. Deformation of the fastener engaging member


28


permits the fastener


34


to be engaged and disengaged from the driving portion


22


with minimal effort. The resiliency of the fastener engaging member


28


, however, is sufficient to retain the fastener


34


on the driving portion


22


until the operator is ready to separate them.





FIG. 3

is a cross-sectional view of the driving portion


24


engaged with a fastener


50


in accordance with the present invention. The fastener


50


includes a tool receiving recess


52


with a plurality of inside surfaces


54


. Again, the number of inside surfaces


54


typically corresponds with the number of tool surfaces


32


on the driving portion


24


. In the embodiment illustrated in

FIG. 3

, the driving portion


24


includes a pair of opposing polymeric fastener engaging members


56


,


58


located at interface


60


between the driving portion


24


and the fastener


50


. The fastener engaging members


56


,


58


form a friction fit with one or more of the inside surfaces


54


to releasably retain the fastener


50


to the driving portion


24


. The fastener engaging members


56


,


58


are preferably located on opposing tool surfaces


32


so that the resulting compressive forces on the fastener engaging member are generally opposing and co-linear.





FIGS. 4

As best illustrated in

FIG. 4



b


, the fastener engaging member


72


is located in a hole


76


formed in the driving portion


70


. Top surface


78


of the fastener engaging member


72


extends above tool surface


74




a


. For a typical hex wrench application, the top surface


78


is about 0.001 inches to about 0.2 inches above the tool surface


74




a


. This dimension can vary depending upon the tool size, the size and weight of the fastener to be retained, the material from which the fastener is constructed and the like. While the hole


76


is typically cylindrical in shape, a variety of shaped recesses can be used for retaining the fastener engaging member


72


, including hemispheric or curvilinear shaped recesses, conical recesses, frusto-conical recesses, hex shaped recesses, and the like.




Forming the hole


76


in the driving portion


70


reduces the torque transmission capability of the tool


68


. Therefore, the size of the hole


76


is preferably minimized. For a hex wrench application, the hole


76


is approximately 0.10 inches to about 0.2 inches in diameter. This dimension can also vary depending upon the tool size, the size and weight of the fastener to be retained, the material(s) from which the fastener engaging member


72


is constructed, the material from which the fastener is constructed and the like. Since most of the torque transmission occurs at the edges

c


between the tool surfaces


74


, the hole


76


for the fastener engaging member

The fastener engaging member


72


can be formed from a variety of polymeric materials, such as nylon, polypropylene, PVC, ABS, cellulose, acetyl, polyethylene, fluoropolymers, polycarbonate, natural or synthetic rubber, and the like. In one embodiment, the fastener engaging member


72


is a separate component that is inserted in the hole


76


. In another embodiment, a polymeric material is deposited in the hole


76


and cured in situ. The top surface


78


can optionally be treated, such as with an abrasive material, so that the height above the tool surface


74


and the shape of the top surface


78


are adapted for the particular application.
