CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a Continuation-In-Part of U.S. patent application Ser. No. 10/447,163, filed May 27, 2003, now U.S. Pat. No. 6,880,435.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to hand tools, and, more particularly, to foldable multipurpose tool kits or combination tools.

2. Description of the Related Art

Multipurpose tool kits or combination tools are well known in the bicycle industry, in particular. This is due primarily to the fact that only a limited number of tools are required to meet most of the mechanical repair needs of bicycles. As a result, bicyclists and technicians find it beneficial and convenient to combine select tools into a single multipurpose tool kit or combination tool.

Among competitive cyclists and bicycle enthusiasts, it is generally desired for multipurpose tool kits to be as compact and lightweight as possible for ease of carrying while riding, but without compromising the sturdiness or performance of the individual tools of the tool kit. At the same time, it is desirable to include as many tools as possible in the tool kit to ensure the cyclists have available, in one tool kit, the tools necessary to repair most mechanical breakdowns likely to be experienced while riding. It should be appreciated, however, that the desire to provide a sturdy, rigid tool kit with a multiple of quality tools necessarily conflicts with the competing interest of providing a compact, lightweight tool kit.

In attempting to satisfy the foregoing competing interests many combination tool kits have been developed. While the various commercially available tool kit designs may serve their intended purpose, heretofore, none have satisfactorily met all the foregoing competing interests and objectives. Heretofore, all known bicycle tool kits have utilized a shackle or clevis type design in which the individual tools are pivotally disposed on a shaft or pin supported at each end by an eyelet or ear. The eyelets or ears may be disposed in the opposing sidewalls of the tool kit body (much like a jack knife design), such as disclosed in U.S. Pat. No. 6,601,481 to Chuang; U.S. Pat. No. 6,216,301 to Rivera; U.S. Pat. No. 5,581,834 to Collins; U.S. Pat. No. 5,450,774 to Chang; and/or U.S. Pat. No. 5,320,004 to Hsiao. In other tool kit designs, the ears or eyelets extend or project from a wide block or base comprising a portion of the tool kit, such as disclosed in U.S. Pat. No. RE37210 to Chuang; U.S. Pat. No. 6,564,678 to Wang; U.S. Pat. No. 6,622,329 to Ostor et al.; and U.S. Pat. No. 6,112,351 to Hawkins et al.

While the foregoing shackle or clevis type designs minimize torque and bending stresses exerted on the pin when the tools are in use due to the pin being supported at both ends, such shackle or clevis type designs necessarily result in greater weight and size of the tool kit as a result of the additional sidewall or larger block base associated with such designs. Thus, it should be appreciated, that by eliminating one of the sidewalls of the foregoing designs or by eliminating one of the ears or eyelets projecting from the block base of the other foregoing designs, substantial weight reduction can be achieved.

The present invention overcomes the shortfalls of other commercially available multipurpose tool kits by providing a lightweight, compact tool kit comprising a plurality tools necessary for meeting most mechanical repair needs experienced with bicycles, without sacrificing tool quality or performance or the sturdiness or rigidity of tool kit as a whole. In addition, as identified herein, the present invention offers other features and advantages over known multipurpose tool kits or combination tools.

SUMMARY OF THE INVENTION

A foldable tool kit having a body constructed of a single elongate beam member to which is pivotally secured a plurality of individual tools pivotally movable about a pin between a folded position and a working position. The plurality of tools may include any type or combination of tools, including, but not limited to hex wrenches, screwdrivers, and chain tools.

In one embodiment, the tool kit includes a single pin supported by the single elongate member substantially transverse and approximate one end of the single elongate member. The pin may have one end cantilevered from the single elongate member or the pin may be supported substantially at its midpoint such that its two ends are cantilevered on each side of the single elongate member.

In another embodiment, rather than a single pin, there may be two pins supported by the single elongate member on opposing sides thereof.

In another embodiment, the tool kit may be substantially as described in either of the two immediately preceding paragraphs but with a second single pin or two pins supported at the other end of the single elongate member.

In all of the foregoing embodiments, the single elongate member preferably includes at least one tool stop to abut the tools in the folded position so that the tools are not free to rotate 360 degrees in one direction. If the tool kit includes tools pivotally secured to the elongate member at each end thereof, as in the preferred embodiment, it should be appreciated that multiple tool stops may be provided, depending on the cantilevered arrangement of the pin and the positioning of the tools on the pin with respect to the single elongate member.

In the preferred embodiment, a tire lever is provided which removable attaches to the single elongate member. Also in the preferred embodiment, the single elongate member removably attaches to and cooperates with secondary tools.

Other objects, advantages, and novel features of the present invention will become apparent from the following detailed description of the invention when considered in conjunction with the accompanying drawings.

 DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several figures, drawing FIG. 1 illustrates one embodiment of a multipurpose tool kit or combination tool of the present invention, designated generally by reference numeral 10.

The tool kit 10 includes a body 12 comprising a single elongate beam member 14 to which is pivotally secured a plurality of individual tools 16 pivotally movable about a pin or shaft 18 (FIG. 3) between a folded position (FIG. 1) and a variety of working positions (FIG. 2). Although the embodiments illustrated in the various drawing figures shows the tools 16 pivotally attached near the ends of the elongate member 14, it should be appreciated that the tools 16 may be pivotally attached anywhere along the length of the elongate member 14.

The tools 16 may include any combination of individual tools. However, as best illustrated in FIG. 3 which is an exploded perspective view of the preferred embodiment of the tool 10, the tools 16 include a range of hex wrenches 20, for example, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 4.0 mm, 5.0 mm and 6.0 mm hex wrenches. In addition, the tools 16 of the preferred tool kit 10, includes a screwdriver 22 (either flathead, Phillips head (not shown) or both) and a six-point or star shaped driver 24, commonly known as a Torx® fitting driver. Also, the tool kit 10 preferably includes an 8.0 mm hex key socket 26 having a 6.0 mm internal hex for removably mounting onto the end of the 6.0 mm hex wrench. The wrenches 20 and screwdrivers 22, 24 are preferably formed from steel bar stock bent at one end to form a circular opening 28 (FIG. 3) through which the pin 18 is received.

Among the tools 16 is also preferably a chain tool 30 for repairing bicycle chains. The chain tool 30 includes a chain support 32 for receiving the bicycle chain and a pressure screw 34 used to force or dislodge the rivets joining the chain links.

Continuing to refer to FIG. 3, the shafts or pins 18 preferably extend through apertures 40 in the elongate member 14. In this embodiment, each of the pins 18 comprise a stud 42 having a head 44 at one end and internal threads 46 at its other end for receiving a threaded fastener 48 also having a head 44. As best illustrated in FIG. 8, when assembled, the two heads 44 at each end of the stud 42 removably secures the individual tools 16 onto the pin 18. In this embodiment, each end of the pin 18 cantilevers from opposite sides of the elongate member 14 whereby each cantilevered end supports a group of tools on each side of the elongate member. The tools are preferably divided such that the tools readily nest with adjacent tools and/or opposing tools while in the folded position, so as to provide a more compact tool kit 10.

An alternative embodiment of the tool kit 10 is illustrated in FIG. 4 wherein the pin 18 is disposed such that only one end of the pins 18 cantilever from the elongate member 14, whereby the individual tools 16 are all disposed on only one side of the elongate member 14. Alternatively, rather the tools 16 being disposed on only one side of the elongate member 14 at both ends, the pins 18 may cantilever from the elongate member 14 in opposing directions, such that half the tools are disposed on one side of the elongate member 14 at one end thereof and the other half of the tools are disposed on the other side of the elongate member 14 at the other end thereof.

Furthermore, it should be appreciated that the pin 18 may take any suitable form recognized by those of skill in the art for pivotally securing tools 16 to an elongate member. For example, as illustrated in FIG. 5, the pin 18 may comprise two separate studs 50 having external threads 52 at one end thereof and a head 44 at the other end. In this embodiment, the threaded ends 52 threadably engage internally threaded apertures 54 extending completely or partially through the elongate member 14. In yet another alternative embodiment, as illustrated in FIG. 6, the pin 18 may comprise a stud 56 having internal threads 46 at each end thereof for receiving a threaded fastener 48. In this embodiment, the stud 56 may be press fit into an aperture 40 in the elongate member 14 or it may be bonded thereto, such as by welding or by an adhesive, or the stud 56 may be formed integral with the elongate member 14. In yet another embodiment, as illustrated in FIG. 7, the pin 18 may comprise a stud 50 having external threads 52 at one end as previously described with respect to the stud 50 illustrated in FIG. 5. However, in the embodiment of FIG. 7, the stud 50 preferably extends through an aperture 40 in the elongate member 14 and is threadably received by a domed nut 56. It should be appreciated that with any of the embodiments of the tool 10 described and illustrated in FIGS. 5-7, the pin 18 may comprise one stud having two cantilevered ends (as best illustrated in FIGS. 3, 6, 7 and 8), one stud having one cantilevered end (as best illustrated in FIG. 4), or two studs having one cantilevered end (as best illustrated in FIG. 5) or any combination thereof.

Also in the preferred embodiment, as best illustrated in FIG. 3, washers 60 or other suitable spacers, are disposed between each of the individual tools 16 and adjacent the heads 44 of the pin 18. The washers 60 between the individual tools serve to separate adjacent tools to prevent their rubbing or interference with when being moved between their folded position and an open working position. The washers 60 adjacent to the heads 44, serve to provide a larger surface area against which the heads 44 can bear, so as to more securely hold the tools 16 onto the pin 18. In addition, a compression washer 62 is preferably provided between the elongate member 14 and the first washer 60 to maintain a tight frictional fit between adjacent tools so as to minimize wobbling or lateral movement of the tools on the pin 18.

As illustrated in FIGS. 2 and 8, in the preferred embodiment, the tool kit 10 includes stops 70 projecting from each side of the elongate member 14 and formed integral therewith. These stops 70 provide a surface against which the tools 16 will abut when in the folded position so that the tools 16 are restrained from pivoting fully about the pin 18 in one direction. As with the pins 18, the stops 70 may take any desired form and may project from the elongate member 14 in any desired manner. For example, rather than being substantially flat and integral with the elongate member 14, the stops 70 may be press fit into an opening 72 in the elongate member 14 as illustrated in FIG. 4. Alternatively, the stops 70 may be cylindrical and threadably connected to the elongate member 14, as illustrated in FIG. 5, for example. Alternatively, the stops 70 may fixed or secured, such as by welding or by an adhesive, to the elongate member. It should also be appreciated that depending on whether the tools 16 are disposed on one side or both sides of the elongate member, the tool may use one stop (as in FIG. 4) or two stops (as best illustrated in FIGS. 5 and 8). Furthermore, depending on the tools, the stop(s) 70 may be disposed substantially at the midpoint of the elongate member (as shown in FIGS. 2 and 3) or the stops may be disposed closer to one end of the elongate member 14.

Additionally, as best illustrated in FIGS. 1-3 and 8, in the preferred embodiment, the tool kit 10 includes a tire lever 80 which preferably removably attaches to the elongate member 14 by any suitable connection, including, for example, by a magnetic connection, a dove tail connection, or any other suitable means of attachment. As best illustrated in FIG. 8, in the preferred embodiment, the tire lever 80 slidably attaches to the elongate member by a dovetail connection, wherein the elongate member 14 includes a male wedge shaped tenon 82 and the tire lever 80 includes a mating female mortise 84 which slidably receives the tenon 82. Also, as best illustrated in FIG. 3, the tire lever 80 also preferably includes a box wrench 86 for matingly receiving the head of the pressure screw 34 of the chain tool 30. The tire lever 80 may further include cutouts 88 for functioning as spoke wrenches or the like.

In addition, as illustrated in FIG. 9, the tool kit 10 of the present invention preferably cooperates with secondary tools 90. In the example of FIG. 9, one such secondary tool 90 is shown as a bottle opener on one end and a flat head screw driver on the other. Other secondary tools 90 which may cooperate with the tool 10 may include knife blades, open end wrenches of varying sizes, a pin spanner, etc. In the embodiment of FIG. 9, the tire lever 80 is shown removed and replaceable with one of the secondary tools 90 attachable to the elongate member 14 by the above described dovetail connection, wherein the supplemental tool 90 includes a mating female mortise 84 adapted to slidably receive the male tenon 82.

Various modification to the embodiments of the tool kit described herein will be readily apparent to those of skill in the art. As such, the present invention is not to be limited to the embodiments described above and illustrated in the drawing figures, but rather should be accorded the widest scope consistent with the spirit and scope of the appended claims.
