BACKGROUND OF THE INVENTION
Pocket multi-tools are generally known. Such tools typically include various folding devices such as scissors, pliers, knife blades, files, saws, screwdrivers, can and bottle openers, and the like. One example of a known pocket multi-tool can be seen in U.S. Pat. No. 5,711,194 (“Anderson 1”). Anderson describes a folding knife, which includes a single or dual folding sleeves, each of which can accommodate a screwdriver bit.
Another example of a multi-tool can be seen in U.S. Pat. No. 6,000,080 (“Anderson 2”). Anderson 2 describes an adaptor that mates with a hand tool such as a folding multipurpose tool to make use of the multipurpose tool as a handle to turn tool bits of various sizes.
BRIEF SUMMARY OF THE INVENTION
The present disclosure describes a folding multi-tool that includes a plurality of folding devices. One of the devices is shaped like a sleeve and accommodates therein an inner sleeve, which in turn accommodates two dual-sided driver bits. The sleeve includes a pronounced feature to facilitate opening of the device relative to the handle, and further provides a flat and/or rectangular feature that can be engaged by a wrench or pliers to increase the torque that can be applied to a fastener engaged by the multi-tool. Moreover, the multi-tool has a dual handle or “butterfly” configuration in which one side is shorter than the other, to provide a tapered overall shape that advantageously provides an improved grip surface for the user. These and other structures and features are described in further detail below.

DETAILED DESCRIPTION OF THE INVENTION
A multi-tool 100 is shown in various operating configurations and from various perspectives in FIGS. 1-9. In reference to these figures, the multi-tool 100 includes a first handle assembly 102 and a second handle assembly 104. The first handle assembly 102 is connected to a first jaw 106 at a first pin joint 108, and the second handle assembly 104 is connected to a second jaw 110 at a second pin joint 112 to form a pair of pliers 114. The pliers shown are blunt-nosed, but needle-nosed or other structures such as a pair of scissors can also be used. The first and second jaws 106 and 110 are pivotally connected to one another at a pivot 116. The pliers 114 are shown in an open position in FIGS. 1 and 2. To close the pliers 114 as shown, for example, in FIG. 3, the first handle assembly 102 can pivot relative to the first jaw 106 about the first pin joint 108 and towards the first jaw 106, and the second handle assembly 104 can pivot relative to the second jaw 110 about the second pin joint 112 and towards the second jaw 110, until internal spaces (as will be described below) in each of the first and second handle assemblies 102 and 104 cover the pliers 114 and meet. When in the open position, the pliers 114 can be operated by a user moving the first and second handle assemblies 102 and 104, and thus also the first and second jaws 106 and 110, about the pivot 116. As can be appreciated, the handles are rotatably prevented from rotating past their open positions relative to the first and second pin joints 108 and 112 in a direction away from the pliers 114 when the pliers 114 are in the open position as shown, e.g., in FIG. 1.
The first handle assembly 102 is made from first and second body plates 118 (see FIGS. 3 and 4) and 120, which are connected to one another at the first pin joint 108 and also at a first outer pin joint 122. Similarly, the second handle assembly 104 is made from first and second body plates 124 and 126, which are likewise connected to one another at the second pin joint 112 and also at a second outer pin joint 128. The pin joints together with the first and second body plates in each of the first and second handle assemblies 102 and 104 define a gap 130 between the corresponding body plates, which accommodate the jaws of the pliers when the multi-tool is closed, and also other devices.
In the illustrated embodiment, the first handle assembly 102 includes a folding bit driver assembly 132, which is pivotally attached to the first handle assembly 102 around a portion of the first outer pin joint 122 that is disposed in the gap 130. The second handle assembly 104 includes a plurality of folding tools 134 that are pivotally attached to the second handle assembly 104 around a portion of the second outer pin joint 128 that is disposed in the gap 130. As can be seen from FIG. 1, an outer end 136 of the second handle assembly 104 is shorter than the outer end of the first handle assembly 102. This difference in length, along with additional features such as grooves 137 aid in gripping the multi-tool during use.
The plurality of folding tools 134 can include any variety of folding tools. As shown in FIG. 3, the plurality of folding tools 134 in the illustrated embodiment includes a knife, a flat screwdriver 138, a bottle/can opener 140 and a file 142, but any other such tools can be used. The folding bit driver assembly 132 includes a tubular socket that accommodates a driver bit 144 and a platform 146 along its length that defines two thumb cavities 148. The platform 146 provides a flat surface, as shown in FIG. 6, which can be used to provide additional torque by engaging the shaft with a wrench or pliers. The platform 146 in the embodiment shown is rectangular and disposed along a plane that is tangential to the outer cylindrical shape of the sleeve of the driver assembly 132. The platform 146 also defines the thumb cavities 148 below to aid the user opening the folding bit driver assembly 132. The thumb cavities 148 are defined on both sides of the platform 146 under an overhang thereof. A width of the platform 146 as shown is about equal to the diameter of the cylindrical sleeve of the driver assembly 132, but a greater width can be used to provide a larger area to engage the driver and also a larger thumb cavity 148. The two thumb cavities 148 have the same size on either side of the sleeve of the driver 132 but can alternatively have different sizes, including having only one thumb cavity on only one side of the sleeve of the driver assembly 132.
A cross section through a portion of the multi-tool 100 is shown in FIGS. 7 and 8, and an enlarged detail view is shown in FIG. 9. In reference to these figures, each of the first and second handle assemblies 102 and 104 includes a stop 150 disposed adjacent the first and second pin joints 108 and 112 and extending transversely at least partially across the gaps 130 such that it contacts features formed in the periphery of the first and second jaws 106 and 110 around the respective pin joints. The stops 150, which are rigid, help transfer motion from the handles to the jaws to operate the pliers 114 when the multi-tool 100 is open, and to also limit travel of the jaws relative to the handles when the multi-tool is closed.
On the opposite, outer ends of the first and second handles 102 and 104, two similar bridges 152 having springs 154 attached on their ends are disposed adjacent the pin joints 122 and 128. As shown in FIG. 8, and also FIG. 9, each bridge 152 spans the width of the gap 130 and includes an extension, which acts as a leaf spring, that resiliently contacts hinge portions of the driver 132 and other devices 134, for example, the opener 138. The springs 154 limit the free rotation of these hinges and help keep the devices in place when unfolded or open, and closed, when the multi-tool 100 is in the closed position.
An enlarged detail of the driver 132 is shown in FIG. 9. In reference to this figure, it can be seen that the driver 132 includes an outer sleeve 156. The outer sleeve 156 had a generally hollow cylindrical shape forming a bore 158 that is open at one end. At an opposite end, the outer sleeve 156 forms a hinge 157 having an opening that is pivotally connected around a portion of the pin joint 122 to permit rotation of the sleeve 156 relative to the handle, e.g., the plate 120. The bore 158 of the outer sleeve 156 has a non-circular cross section, for example, a hexagonal cross section, which includes flats that engage corresponding flats on a driven component disposed therein to transmit torque therebetween. While the bore 158 can accommodate a driver bit directly, in the illustrated embodiment, an inner sleeve 160 having two opposing bores 162 and 164 is disposed in the outer sleeve 156. Each bore 162 and 164 rotatably and releasably slidably engages and includes a driver bit such as the driver bit 144 and a second driver bit 166. Each driver bit 144 and 166 has dual working ends, for example, small or large flathead or phillips head drivers, to provide a total of four bits that can be used by removing, rotating and replacing the inner sleeve 160 and each of the driver bits 144 and 166 into the outer sleeve 156. As can be seen from the figures, the outer sleeve has a hexagonal inner and outer profile that is dimensioned such that the outer sleeve rotatably engages the outer sleeve 156 and also each of the driver bits 144 and 166 rotatably and slidably engages the bores 162 and 164 of the inner sleeve 160. The rotatable engagement is provided in all cases by the hexagonal profiles. The slidable engagement is provided by spring loaded spheres 168, which are disposed between the outer and inner sleeves, and also between each of the two driver bits and the inner sleeve bores.
