Definitions
- the present invention relates generally to the field of multi-function tools. More particularly, the present invention relates to a multi-function tool having a tool cartridge containing a slide lock mechanism and a plurality of ancillary tools.
- the pliers head generally includes a pair of jaws that are attached to the handles.
- the jaws may be removable, or reversible, depending on the type of tool.
- the jaws can also have replaceable cutting inserts, such as those described in U.S. application Ser. No. 09/368,781, which is incorporated herein by reference.
- Types of additional implements include scissors, screwdrivers, files, knives, or bottle openers.
- U.S. Pat. Nos. 5,946,752 and 6,105,260 issued on Sep. 7, 1999 to Parrish and Aug. 22, 2000 to Parrish et al. disclose types of additional implements. These patents are incorporated herein by reference.
- Types of locks include slide locks or liner locks.
- handles may not be biased into their operative and folded positions, respectively. Therefore, the handles may inadvertently come out of their folded configuration, or close when the user desires the handles to be in their open position.
- Another disadvantage of conventional multi-function tools is that the additional implements may be directly attached to the handles via an axle. This creates both manufacturing and end-user difficulties. From the manufacturing standpoint, the manufacturer may wish to use a variety of different tool packages with a standardized set of multi-function tool handles. This is inefficient if the implements are individually directly attached to the handles. Additionally, if the end user wishes to replace one or more of the ancillary implements, or disassemble the handles for some reason, removal of the sides of the handles disassembles all of the ancillary implements simultaneously, creating reassembly difficulties.
- Another disadvantage of conventional multi-function tools is that the cutting or wire stripping portion of the pliers head is not replaceable. Therefore, if the cutting insert becomes damaged or dull, the entire head of the tool must be replaced, if that is even possible, rather than simply replacing the cutting insert.
- Another disadvantage of conventional multi-function tools is that the anti-rotational washers that may be used to prevent transmission of torque between the ancillary implements have fingers that extend into a slot in the handles. The slot extends through the handle, and therefore may be viewed from the exterior of the tool.
- the handles may have a cut-out portion to allow a user to access folded interior tools.
- This design relies on the user's ability to engage the folded tools with a thumb or fingernail. Additionally, the cut-out portion detracts from the overall aesthetic appearance of the multi-function tool.
- a multi-function tool in which the handles are biased in both the opened and closed positions. Further, it would be advantageous to have a multi-function tool with a replaceable cutting insert in the head. Further, it would be advantageous to have a multi-function tool that has a tool cartridge that may be separately installed into the handles. Further, it would be advantageous to have a multi-function tool that does not have a through slot in the handles to engage the fingers of anti-rotational washers. Further, it would be advantageous to have a multi-function tool that has a handle design that allows for easy manufacture. Further, it would be advantageous to have a multi-function tool that does not have a cut-out portion in the handle through which the user must extend a finger or a thumbnail to engage one of the retracted tools.

- the cutting inserts 42 , 44 work together to cut material placed therebetween.
- the cutting inserts 42 , 44 each have a notch 46 , 48 that may be used to strip wires.
- the notch 46 , 48 can be of various sizes for different applications.
- the notches 46 , 48 create an aperture when the jaws 28 , 30 are closed. In another, the notches 46 , 48 cut through items placed therebetween.
- the cutting inserts 42 , 44 can have multiple cutting edges allowing rotation of the cutting insert 42 , 44 .
- Each cutting insert 42 , 44 has a beveled region 45 , 47 that terminates in a cutting edge.
- the angle of the beveled region 45 , 47 can vary depending on the preferred use of the cutting inserts 42 , 44 . Additionally, because the cutting inserts 42 , 44 are removable and rotatable, each cutting insert 42 , 44 can have three different beveled regions 45 , 47 with different bevel angles to allow the user to selectively choose the preferred configuration.
- the jaws 28 , 30 combine to make a pair of pliers
- the head 11 could be any type of tool that uses two jaws 28 , 30 .
- the jaws 28 , 30 are preferably made of steel, but may also be made of other suitable materials such as aluminum.
- the cutting inserts 42 , 44 preferably are made of a hardened tool steel and have a tungsten carbide cutting surface to provide added wear resistance.
- a benefit of having a removable cutting insert 42 , 44 is that by simply removing the fasteners 114 , the cutting insert 42 , 44 may be easily rotated or replaced by the user.

- the second side 74 has a second flange 90 extending perpendicularly therefrom.
- the first flange 88 has a groove 92 (FIG. 14).
- the second flange 90 has a tongue 94 (FIG. 14).
- the sides 72 , 74 can be attached together by screws 96 that are threaded into axles 20 , 22 , 24 , 26 .
- the screws 96 not only join the handle sides 72 , 74 but help maintain the tool cartridge 16 and spring arm insert 68 in position by fixing the axles 20 , 22 , 24 , 26 with respect to the handle sides 72 , 74 .
- the tongue 94 and groove 92 fit together when the first side and second side are assembled to create a three-sided channel 99 (FIGS. 14 and 18).
- a web 91 (FIG. 14) is created by the two joined flanges 88 , 90 .
- the remaining portion of the assembled handle has a longitudinal slot or opening 98 between the two sides 72 , 74 of the handle 12 (FIG. 18).
- the handle 12 may be attached to the head 11 in the following manner.
- a spring arm insert 68 has a pair of spring arm insert apertures 77 , 79 that line up with the first handle apertures 76 , 78 . Accordingly, the first and second handle sides 72 , 74 and the spring arm insert 68 may be coupled to the first axle 20 along with the tang 38 .
- a pair of spacers 81 may also be coupled to the first axle 20 on either side of the tang 38 . When the screws 96 are threaded into the first axle 20 , the handle 12 is thereby rotatably coupled to the head 11 .
- each handle 12 , 14 is constructed using two separate sides 72 , 74 and fasteners 96 , components may be inserted and removed after assembly of the handles 12 , 14 . Additionally, interchangeable components, such as spring arm insert 68 may be captured between the two sides of each handle once the two sides are attached.
- the handles 12 , 14 are assembled by first inserting any desired interchangeable components between the two handle sides 72 , 74 .
- the tongue 94 and groove 92 are meshed to ensure that the web 91 is flat.
- the screws 96 can then be used to complete the assembly.
- the handles 12 , 14 are preferably made of steel or aluminum. Exterior surface 100 of handles 12 , 14 has textured surface areas 104 to provide extra gripping ability as well as a more comfortable fit in the user's hand.
- each handle 12 , 14 has a curved profile.
- the curved structure allows the tool to fit better into user's hand both when handles 12 , 14 are in the opened position, as well as in the folded position.
- the tool cartridge 16 resides within each handle 12 , 14 . Because the tool cartridges 16 are similar, only one set of reference numerals will be used for convenience.
- the tool cartridge 16 has a first side 118 , a second side 120 , and a cartridge bottom 122 connecting the two sides. Each side 118 , 120 fits into a cartridge recess 124 (see FIG. 5) in the first side 72 and the second side 74 of the handle 12 .
- the cartridge bottom 122 is integral with the cartridge sides 118 , 120 and extends the length of the tool cartridge 16 .
- a portion of the cartridge bottom can comprise a plastic insert.
- the use of the cartridge recesses 124 permits the capture of the tool cartridge 16 without the use of fasteners.
- the tool cartridge 16 may be inserted between the handle sides 72 , 74 prior to assembly of the handle 12 , 14 , and captured therebetween once the handle sides 72 , 74 are coupled together.
- the capture construction and method of assembly is superior because of the resultant reduction in parts, such as springs and fasteners, and lighter weight of the multi-function tool 10 .
- a cartridge axle 126 which may serve as second axle 24 , 26 , extends between the first side 118 and the second side 120 of the cartridge.
- the cartridge axle 126 can have threaded recesses 128 to receive screws 96 (see FIGS. 5 and 14).
- the cartridge 16 is secured to the handle 12 by means of screws 96 inserted through the second apertures 80 , 82 of the handle and threaded into the cartridge axle recesses 128 .
- the cartridge axle 126 is used to adjust the tension of the ancillary tools 132 .
- the cartridge axle 126 has a keyed head 130 that fits into a corresponding recess 129 in the tool cartridge 16 .
- a screw 96 is threaded into the recess 128 distal the keyed head 130 , the keyed head 130 is drawn through the recess 129 to compress the ancillary tools 132 .
- the interference between keyed head 130 and keyed opening 129 after assembly prevents the cartridge axle 126 from rotating.
- the amount of compression on the ancillary tools 132 after assembly is determined by the tightness of screws 96 .
- Each ancillary tool may be rotatably coupled to the cartridge axle 126 .
- Each ancillary tool has a working portion 134 and a tang 136 .
- the tang 136 has an aperture 138 through which the cartridge axle 126 travels.
- the tang 136 also has an associated notch 168 and an associated flattened portion 170 .
- the working portion 134 of the ancillary tools 132 can include such implements as screwdrivers, files, scissors, knives, bottle openers, rulers, corkscrews, and assorted other cutting instruments.
- a retaining finger 140 Extending outward from the cartridge bottom 122 is a retaining finger 140 .
- the retaining finger 140 is sloped away from the cartridge bottom 122 .
- An end 142 of the retaining finger 140 extends at a greater angle relative to cartridge bottom 122 .
- a wedge lock 144 includes a wedge plate 146 , a compression spring 148 , and a spring housing 150 .
- the wedge plate 146 has a first planar side 152 disposed against the bottom 122 of the tool cartridge 16 and a second planar side 154 facing the ancillary tools 132 (FIG. 15).
- the second side 154 has a beveled region 166 distal compression spring 148 .
- the wedge plate 146 has wings 156 that extend outward through the tool cartridge slots 158 (FIG. 6) and further through handle slots 84 , 86 (FIG. 5).
- the wings 156 may have a serrated edge 157 (FIG. 18) to aid in frictionally engaging a user's thumb and fingers.
- the wedge plate 146 retains one end of the compression spring 148 .
- the compression spring 148 is located within the spring housing 150 .
- the spring housing 150 is attached to the bottom 122 of the tool cartridge 16 .
- the spring housing 150 has a spring retaining finger 162 on an end distal the wedge plate 146 .
- the spring housing 150 is shaped to fit within a wedge plate notch 164 to allow the wedge plate 146 to be moved back and forth relative to the fixed spring housing 150 .
- integral with the plastic insert can be the spring housing 150 .
- the integral design eliminates the necessity of fasteners used to attach the spring housing 150 to the bottom 122 of the tool cartridge 16 .
- FIGS. 15 - 17 show the operation of the wedge plate 146 .
- the wedge plate 146 When all of the ancillary tools 132 are in the closed position, the wedge plate 146 is biased against the notches 168 of the ancillary tools 132 as shown in FIG. 15. In this position, the wedge plate 146 provides a closing torque on the ancillary tools 132 to maintain the ancillary tools 132 in their closed position.
- the ancillary tools 132 are not locked in the closed position however, in that the ancillary tools 132 may be opened by the user without manually disengaging the wedge plate 146 .
- the notch 168 of the ancillary tool 132 can move the wedge plate 146 away from its first operative position automatically as the ancillary tool 132 is rotated from its folded position.
- FIG. 16 shows the position of the wedge plate 146 when an ancillary tool is in an intermediate position between its fully closed and fully opened positions.
- the compression spring 148 biases the wedge plate 146 into the operative position shown in FIG. 17.
- the beveled region 166 of the wedge plate 146 is disposed against the flattened region 170 of the tang 136 of the opened ancillary tool 132 .
- the flattened region 170 is disposed at a slight angle relative to the tool cartridge bottom 122 , creating a v-shaped opening for insertion of the wedge plate 146 .
- the wedge plate 146 locks the ancillary tool 132 in the fully opened position, preventing rotation of the ancillary tool 132 until the wedge plate 146 is disengaged from the ancillary tool.
- the remaining ancillary tools 132 may still be rotated into an opened position. The wedge plate 146 will lock multiple tools in their fully opened position if desired.
- the wedge lock 144 To close a locked open ancillary tool 132 , the wedge lock 144 must be disengaged from the ancillary tool 132 .
- the disengagement may be effected in two ways. First, a user may retract the wedge plate 146 manually by grasping the wings 156 of the wedge plate 146 and moving the wedge plate 146 out from engagement with the tang 136 of the opened tool.
- a second way of disengaging the wedge plate 146 is to partially remove a second ancillary tool 132 from its closed position. When an ancillary tool 132 is rotated from its closed position toward its open position, the tang 136 of the ancillary tool 132 will automatically slide the wedge plate 146 away from its locked position.
- the wedge lock 144 will be automatically unlocked (see FIG. 16), disengaging the beveled region 166 from the flattened portion 170 of the locked fully opened tool 132 .
- the fully opened tool 132 may then be closed while the wedge plate 146 is disengaged.
- disposed between ancillary tools 132 are a number of washers 180 .
- the washers 180 each have a profile that roughly matches the tangs 136 of the ancillary tools 132 when the ancillary tools 132 are in the closed position.
- the washers 180 have a washer finger 182 that extends into a transverse slot 184 in the bottom 122 of the tool cartridge 16 . Because the washer fingers 182 extend into the transverse slot 184 , the washers 180 do not rotate.
- the adjacent ancillary tools 132 remain in position because the washer 180 prevents torque from being transmitted from the tool 132 being rotated to an adjacent tool 132 .
- the washer finger 182 extends into the transverse slot 184 .
- the web 91 Next to the transverse slot 184 is the web 91 , which does not have a corresponding slot. Accordingly, the washer 182 and the slot 184 are not visible from the exterior of an assembled handle 12 , 14 because the web 91 covers the slot 184 .
- the user To rotate the ancillary tools 132 from their folded to their opened position, the user must grasp or engage the ancillary tools 132 in some fashion.
- Conventional handle designs have a cut-out portion in the sides of the handles 12 , 14 to allow a user to access a tool 132 disposed adjacent to the side 72 of the handle 12 , 14 .
- the tool 132 conventionally has a recessed portion that a user may insert a fingernail into to aid in rotating the tool 132 from its closed position.
- the multi-function tool 10 has an ancillary tool 132 with a nub 186 that a user may use to engage the ancillary tool adjacent the side of the handle 12 , 14 .
- the nub 186 resides in a handle notch 190 when the ancillary tool 132 is in the stowed position (see FIG. 1).
- the user may easily open the stowed tool by engaging the nub 186 to pivot ancillary tool 132 from within the handle 12 , 14 .
- the surface of the nub 186 is textured to aid in engaging with the user's thumb or finger.
- An ancillary tool 132 disposed inward from the sides of the handles 12 , 14 may have a catch structure 188 (see FIG. 3) that a user may use to rotate an interior ancillary tool 132 outward without first rotating the other ancillary tools 132 that are closer to the handle 12 , 14 sides outward.
- the spring arm insert 68 is disposed between handle sides 72 , 74 proximate the jaw tang 38 .

No. 6,305,041, which is a continuation of application Ser. No. 08/771,449, filed Dec. 20, 1996, now U.S. Pat. No. 6,088,860. application Ser. No. 09/756,547 is also a continuation-in-part of application Ser. No. 09/368,781, filed Aug. 5, 1999.
- The present invention relates generally to the field of multi-function tools. More particularly, the present invention relates to a multi-function tool having a tool cartridge containing a slide lock mechanism and a plurality of ancillary tools.
- Conventional multi-function tools generally have a pair of handles, a pliers head, and a variety of additional tools. The pliers head generally includes a pair of jaws that are attached to the handles. The jaws may be removable, or reversible, depending on the type of tool. The jaws can also have replaceable cutting inserts, such as those described in U.S. application Ser. No. 09/368,781, which is incorporated herein by reference. Types of additional implements include scissors, screwdrivers, files, knives, or bottle openers. U.S. Pat. Nos. 5,946,752 and 6,105,260 issued on Sep. 7, 1999 to Parrish and Aug. 22, 2000 to Parrish et al. disclose types of additional implements. These patents are incorporated herein by reference.
- Conventional multi-function tools generally have the ability to fold into a compact state. This can be done by rotating the handles about the jaws to result in a position whereby the jaws are folded into the handles. This configuration is shown in U.S. Pat. No. 6,047,426 to McIntosh et al.
- The tangs of the respective plier jaws can be slidably affixed to the respective handles such that the jaws can be slidably retracted into the interior of the handle channels. Examples of such multi-function tools are described in U.S. Pat. Nos. 5,142,721 and 5,212,844 issued on Sep. 1, 1992 and May 25, 1993, respectively to Sessions et al., and U.S. Pat. No. 6,088,860 issued Jul. 18, 2000 to Poehlmann et al. These patents are incorporated herein by reference.
- Conventional multi-function tools typically have some means to lock the additional implements into the opened position. Types of locks include slide locks or liner locks.
- One disadvantage of conventional multi-function tools is that the handles may not be biased into their operative and folded positions, respectively. Therefore, the handles may inadvertently come out of their folded configuration, or close when the user desires the handles to be in their open position.
- Another disadvantage of conventional multi-function tools is that the additional implements may be directly attached to the handles via an axle. This creates both manufacturing and end-user difficulties. From the manufacturing standpoint, the manufacturer may wish to use a variety of different tool packages with a standardized set of multi-function tool handles. This is inefficient if the implements are individually directly attached to the handles. Additionally, if the end user wishes to replace one or more of the ancillary implements, or disassemble the handles for some reason, removal of the sides of the handles disassembles all of the ancillary implements simultaneously, creating reassembly difficulties.
- Another disadvantage of conventional multi-function tools is that the handles are difficult to manufacture because of the difficulty in aligning the two sides of the handles to create a flat exterior surface.
- Another disadvantage of conventional multi-function tools is that the cutting or wire stripping portion of the pliers head is not replaceable. Therefore, if the cutting insert becomes damaged or dull, the entire head of the tool must be replaced, if that is even possible, rather than simply replacing the cutting insert.
- Another disadvantage of conventional multi-function tools is that the anti-rotational washers that may be used to prevent transmission of torque between the ancillary implements have fingers that extend into a slot in the handles. The slot extends through the handle, and therefore may be viewed from the exterior of the tool.
- Another disadvantage of conventional multi-function tools is that the handles may have a cut-out portion to allow a user to access folded interior tools. This design relies on the user's ability to engage the folded tools with a thumb or fingernail. Additionally, the cut-out portion detracts from the overall aesthetic appearance of the multi-function tool.
- Accordingly, it would be advantageous to have a multi-function tool in which the handles are biased in both the opened and closed positions. Further, it would be advantageous to have a multi-function tool with a replaceable cutting insert in the head. Further, it would be advantageous to have a multi-function tool that has a tool cartridge that may be separately installed into the handles. Further, it would be advantageous to have a multi-function tool that does not have a through slot in the handles to engage the fingers of anti-rotational washers. Further, it would be advantageous to have a multi-function tool that has a handle design that allows for easy manufacture. Further, it would be advantageous to have a multi-function tool that does not have a cut-out portion in the handle through which the user must extend a finger or a thumbnail to engage one of the retracted tools.
- One embodiment of the invention relates to a multi-function tool having a head with a first jaw and a second jaw joined at an axis. A first handle is coupled to the first jaw, and the first handle has a channel. A second handle is coupled to the second jaw. A first scissors piece is pivotally secured to the first handle. A second scissors piece is pivotally secured to the first scissors piece at a scissors axle. The second scissors piece has a working portion and a tang. The two scissors pieces have a first configuration suitable for storage in the channel, and a second configuration suitable for operation, wherein the tang is positioned above the channel in the second configuration.
- A further embodiment of the invention relates to a multi-function tool having a head with a first jaw and a second jaw joined at an axis. The first and second jaws have a working portion and a tang. A first handle is coupled to the first jaw and a second handle is coupled to the second jaw. The handles have a folded configuration and an unfolded configuration. A spring in the head biases the working portions apart from one another, wherein the handles are biased in an open position when the handles are in the unfolded configuration and the handles are biased in a closed position when the handles are in the folded configuration.
- A further embodiment of the invention relates to a method of operating a multi-function tool. The tool has a scissors tool including a first piece and a second piece. The method includes the steps of unfolding the scissors tool by rotating the scissors tool in a first direction of rotation, and replacing the scissors tool in an operative configuration by rotating the second piece relative to the first piece in a second direction of rotation that is opposite of the first direction of rotation.
- A still further embodiment of the invention relates to a multi-function tool having a head with a first jaw and a second jaw joined at an axis. The first jaw has a working portion and a tang, and the second jaw has a working portion and a tang. A first handle is coupled to the first jaw at a first axle and a second handle is coupled to the second jaw at a second axle. A replaceable cutting insert is coupled to the head. The cutting insert has two pieces, one coupled to each of the jaws. The pieces each have a notch.
- A still further embodiment of the invention relates to a multi-function tool having a head with a first jaw and a second jaw joined at an axis. A first handle is coupled to the first jaw, and the first handle has a first channel. A second handle is coupled to the second jaw, and the second handle has a second channel. The first and second handles each have a first side and a second side. The first side of each handle has a tongue, and the second side of each handle has a groove configured to receive the tongue.
- A still further embodiment of the invention relates to a multi-function tool having a head with a first jaw and a second jaw joined at an axis. The first and second jaws each have a working portion and a tang. The first handle is coupled to the first jaw, and a second handle is coupled to the second jaw. The first and second handles each have a channel. The handles have a folded configuration and an unfolded configuration. A cam surface is on each of the tangs and a spring arm is coupled to each handle. Each spring arm is configured to engage one of the cam surfaces wherein the handles snap into the folded configuration due to the interaction between the spring arm and the cam surface, and wherein the handles snap into the unfolded configuration due to the interaction between the spring arm and the cam surface.
- A further embodiment of the invention relates to a method of manufacturing or repairing the handle of a multi-function tool. The handle has a first side and a second side. The method includes the steps of providing a tool cartridge having a plurality of ancillary tools, inserting the tool cartridge between the two sides of the handle, and fastening the sides together using a plurality of fasteners. The tool cartridge is captured between the first and second sides.

handle 12 is shown. Theother handle 14 is of similar construction. For convenience, reference numerals will only be used forhandle 1 2. Thehandle 12 hasfirst side 72 andsecond side 74. Eachside first aperture second aperture second aperture handle slot first side 72 has afirst flange 88 extending perpendicularly therefrom. Thesecond side 74 has asecond flange 90 extending perpendicularly therefrom. Thefirst flange 88 has a groove 92 (FIG. 14). Thesecond flange 90 has a tongue 94 (FIG. 14). Thesides screws 96 that are threaded intoaxles screws 96 not only join the handle sides 72, 74 but help maintain thetool cartridge 16 andspring arm insert 68 in position by fixing theaxles tongue 94 andgroove 92 fit together when the first side and second side are assembled to create a three-sided channel 99 (FIGS. 14 and 18). A web 91 (FIG. 14) is created by the two joinedflanges sides - Referring to FIGS. 5 and 7, the
handle 12 may be attached to thehead 11 in the following manner. Aspring arm insert 68 has a pair of springarm insert apertures first handle apertures spring arm insert 68 may be coupled to thefirst axle 20 along with thetang 38. A pair ofspacers 81 may also be coupled to thefirst axle 20 on either side of thetang 38. When thescrews 96 are threaded into thefirst axle 20, thehandle 12 is thereby rotatably coupled to thehead 11. - Because each handle12, 14 is constructed using two
separate sides fasteners 96, components may be inserted and removed after assembly of thehandles spring arm insert 68 may be captured between the two sides of each handle once the two sides are attached. - The
handles sides tongue 94 andgroove 92 are meshed to ensure that theweb 91 is flat. Thescrews 96 can then be used to complete the assembly. - The
handles Exterior surface 100 ofhandles surface areas 104 to provide extra gripping ability as well as a more comfortable fit in the user's hand. - Referring to FIGS. 1 and 2, once assembled, each handle12, 14 has a curved profile. The curved structure allows the tool to fit better into user's hand both when handles 12, 14 are in the opened position, as well as in the folded position.
- Referring to FIGS. 5, 6, and12, the
tool cartridge 16 resides within eachhandle tool cartridges 16 are similar, only one set of reference numerals will be used for convenience. Thetool cartridge 16 has afirst side 118, asecond side 120, and acartridge bottom 122 connecting the two sides. Eachside first side 72 and thesecond side 74 of thehandle 12. - In an exemplary embodiment, the
cartridge bottom 122 is integral with the cartridge sides 118, 120 and extends the length of thetool cartridge 16. In an alternative embodiment, a portion of the cartridge bottom can comprise a plastic insert. - The use of the cartridge recesses124 permits the capture of the
tool cartridge 16 without the use of fasteners. Thetool cartridge 16 may be inserted between the handle sides 72, 74 prior to assembly of thehandle multi-function tool 10. - A
cartridge axle 126, which may serve assecond axle first side 118 and thesecond side 120 of the cartridge. Thecartridge axle 126 can have threadedrecesses 128 to receive screws 96 (see FIGS. 5 and 14). Thecartridge 16 is secured to thehandle 12 by means ofscrews 96 inserted through thesecond apertures - The
cartridge axle 126 is used to adjust the tension of theancillary tools 132. Thecartridge axle 126 has a keyedhead 130 that fits into acorresponding recess 129 in thetool cartridge 16. As ascrew 96 is threaded into therecess 128 distal thekeyed head 130, thekeyed head 130 is drawn through therecess 129 to compress theancillary tools 132. The interference betweenkeyed head 130 and keyedopening 129 after assembly prevents thecartridge axle 126 from rotating. The amount of compression on theancillary tools 132 after assembly is determined by the tightness ofscrews 96. - Referring to FIG. 6 number of
ancillary tools 132 may be rotatably coupled to thecartridge axle 126. Each ancillary tool has a workingportion 134 and atang 136. Thetang 136 has an aperture 138 through which thecartridge axle 126 travels. Thetang 136 also has an associatednotch 168 and an associated flattenedportion 170. The workingportion 134 of theancillary tools 132 can include such implements as screwdrivers, files, scissors, knives, bottle openers, rulers, corkscrews, and assorted other cutting instruments. - Extending outward from the
cartridge bottom 122 is a retainingfinger 140. The retainingfinger 140 is sloped away from thecartridge bottom 122. Anend 142 of the retainingfinger 140 extends at a greater angle relative tocartridge bottom 122. - Referring to FIGS. 12 and 13, a
wedge lock 144 includes awedge plate 146, acompression spring 148, and aspring housing 150. Thewedge plate 146 has a firstplanar side 152 disposed against thebottom 122 of thetool cartridge 16 and a secondplanar side 154 facing the ancillary tools 132 (FIG. 15). Thesecond side 154 has abeveled region 166distal compression spring 148. Thewedge plate 146 haswings 156 that extend outward through the tool cartridge slots 158 (FIG. 6) and further throughhandle slots 84, 86 (FIG. 5). Thewings 156 may have a serrated edge 157 (FIG. 18) to aid in frictionally engaging a user's thumb and fingers. - The
wedge plate 146 retains one end of thecompression spring 148. Thecompression spring 148 is located within thespring housing 150. Thespring housing 150 is attached to thebottom 122 of thetool cartridge 16. Thespring housing 150 has aspring retaining finger 162 on an end distal thewedge plate 146. Thespring housing 150 is shaped to fit within awedge plate notch 164 to allow thewedge plate 146 to be moved back and forth relative to the fixedspring housing 150. - When a plastic insert is used as a portion of the
tool cartridge bottom 122, integral with the plastic insert can be thespring housing 150. The integral design eliminates the necessity of fasteners used to attach thespring housing 150 to thebottom 122 of thetool cartridge 16. - FIGS.15-17 show the operation of the
wedge plate 146. When all of theancillary tools 132 are in the closed position, thewedge plate 146 is biased against thenotches 168 of theancillary tools 132 as shown in FIG. 15. In this position, thewedge plate 146 provides a closing torque on theancillary tools 132 to maintain theancillary tools 132 in their closed position. Theancillary tools 132 are not locked in the closed position however, in that theancillary tools 132 may be opened by the user without manually disengaging thewedge plate 146. Thenotch 168 of theancillary tool 132 can move thewedge plate 146 away from its first operative position automatically as theancillary tool 132 is rotated from its folded position. FIG. 16 shows the position of thewedge plate 146 when an ancillary tool is in an intermediate position between its fully closed and fully opened positions. - Once the
ancillary tool 132 is in its fully opened position, thecompression spring 148 biases thewedge plate 146 into the operative position shown in FIG. 17. In this position, thebeveled region 166 of thewedge plate 146 is disposed against the flattenedregion 170 of thetang 136 of the openedancillary tool 132. In the locked open position, the flattenedregion 170 is disposed at a slight angle relative to thetool cartridge bottom 122, creating a v-shaped opening for insertion of thewedge plate 146. In this position, thewedge plate 146 locks theancillary tool 132 in the fully opened position, preventing rotation of theancillary tool 132 until thewedge plate 146 is disengaged from the ancillary tool. In the position shown in FIG. 17, the remainingancillary tools 132 may still be rotated into an opened position. Thewedge plate 146 will lock multiple tools in their fully opened position if desired. - Referring to FIG. 17, when an
ancillary tool 132 is locked open, thewedge plate 146 is pushed into an interference fit with the flattenedregion 170 of the lockedancillary tool 132 by thecompression spring 148. Thewedge plate 146 does not extend fully as shown in FIG. 15 when locking anancillary tool 132. This design allows for greater variability in manufacturing tolerances.Wedge plate 146 rests againstnotch 168 of the closedancillary tool 132 when all ofsuch tools 132 are folded as shown in FIG. 15. If thewedge plate 146 were to reside in the same position when locking anancillary tool 132 into the open position as shown in FIG. 17, variability in the positioning of thenotch 168, or thickness of thewedge plate 146 could allow play in the fully openedtool 132. Thus the interference fit shown in FIG. 17 betweenbeveled region 166 and flattenedregion 170 allows for more manufacturing variability. - To close a locked open
ancillary tool 132, thewedge lock 144 must be disengaged from theancillary tool 132. The disengagement may be effected in two ways. First, a user may retract thewedge plate 146 manually by grasping thewings 156 of thewedge plate 146 and moving thewedge plate 146 out from engagement with thetang 136 of the opened tool. A second way of disengaging thewedge plate 146 is to partially remove a secondancillary tool 132 from its closed position. When anancillary tool 132 is rotated from its closed position toward its open position, thetang 136 of theancillary tool 132 will automatically slide thewedge plate 146 away from its locked position. Therefore, if a secondancillary tool 132 is partially rotated from its closed position, thewedge lock 144 will be automatically unlocked (see FIG. 16), disengaging thebeveled region 166 from the flattenedportion 170 of the locked fully openedtool 132. The fully openedtool 132 may then be closed while thewedge plate 146 is disengaged. - Referring to FIG. 6, disposed between
ancillary tools 132 are a number ofwashers 180. Thewashers 180 each have a profile that roughly matches thetangs 136 of theancillary tools 132 when theancillary tools 132 are in the closed position. Thewashers 180 have awasher finger 182 that extends into atransverse slot 184 in thebottom 122 of thetool cartridge 16. Because thewasher fingers 182 extend into thetransverse slot 184, thewashers 180 do not rotate. Thus when anancillary tool 132 is rotated about thecartridge axle 126, the adjacentancillary tools 132 remain in position because thewasher 180 prevents torque from being transmitted from thetool 132 being rotated to anadjacent tool 132. - Referring to FIG. 16, the
washer finger 182 extends into thetransverse slot 184. Next to thetransverse slot 184 is theweb 91, which does not have a corresponding slot. Accordingly, thewasher 182 and theslot 184 are not visible from the exterior of an assembledhandle web 91 covers theslot 184. - To rotate the
ancillary tools 132 from their folded to their opened position, the user must grasp or engage theancillary tools 132 in some fashion. Conventional handle designs have a cut-out portion in the sides of thehandles tool 132 disposed adjacent to theside 72 of thehandle tool 132 conventionally has a recessed portion that a user may insert a fingernail into to aid in rotating thetool 132 from its closed position. - Referring to FIGS. 3 and 5, instead of a cut-out portion in the
handle multi-function tool 10 has anancillary tool 132 with anub 186 that a user may use to engage the ancillary tool adjacent the side of thehandle nub 186 resides in ahandle notch 190 when theancillary tool 132 is in the stowed position (see FIG. 1).
