In some embodiments, assembly of the tool 20 as shown in
In some methods of forming a workpiece W, the workpiece is slipped over the forming pegs 42, 44. The proximal portions 54, 84 of the handles 26, 28 are moved toward one another to move the distal ends 52, 82 away from one another in a stretching movement, thus moving the forming pegs 42, 44 away from one another along the first line of action A20 of the tool 20. The workpiece W is optionally a loop of wire, a loop of flat metal, or other material that is stretched and formed to the first and second forming pegs 42, 44 during the stretching movement, or outward spacing of the distal ends 52, 82 along the line of action A20. Although some embodiments include a stretching movement, as subsequently described, in some other embodiment tools, actuation of the handles thereof results in a clamping movement.
In some embodiments, the first perforation plate 150 includes a body 170 that is substantially block- or plate-shaped and having an upper surface 172. The body 170 has a first plurality of receptacles 174, also described as peg apertures, and a first pivot receptacle 176 formed into the upper surface 172. The body 170 also has a first slider lumen 178 and a second slider lumen 180 for receiving the first and second sliders 154, 156, respectively.
Each of the plurality of receptacles 174 is optionally of a similar diameter to the first and second receptacles 70, 100. Such an arrangement adds versatility, as forming pegs are able to be interchangeably arranged directly in the handles 26, 28 or in the first perforation plate 150 as desired. In some embodiments, the first plurality of receptacles 174 is only partially formed into the first perforation plate 150 (rather than through the first perforation plate 150) to help avoid use of additional retaining mechanisms with the first perforation plate 150.

In some embodiments, the second perforation plate 152 includes a body 190 that is substantially block- or plate-shaped and has an upper surface 192. The body 190 has a second plurality of receptacles 194, also described as peg apertures, and a second pivot receptacle 196 formed into the upper surface 192. The body 190 also has a first slider lumen 198 and a second slider lumen 200 for receiving the first and second sliders 154, 156, respectively.
Each of the plurality of receptacles 194 is optionally of a similar diameter to the first and second receptacles 70, 100. Such an arrangement adds versatility, as the forming pegs are able to be interchangeably arranged directly in the handles 26, 28, the first perforation plate 150, or in the second perforation plate 152 as desired. In some embodiments, the second plurality of receptacles 194 is only partially formed into the body 190 (rather than through the body 190) to help avoid use of additional retaining mechanisms. The second plurality of receptacles 194 optionally extend substantially perpendicular to the upper surface 192 and/or substantially parallel to the first and second receptacles 70, 100 upon assembly of the second perforation plate 152 to the second handle 28.
The second pivot receptacle 196 optionally passes through the body 190 and includes female threading adapted to mate with the second pivot fastener 160 (
Similarly to the first perforation plate 150, the second perforation plate 152 is optionally formed of metal or polymeric material. In some embodiments, the second perforation plate 152 is provided to an end user (not shown), for example in a kit of parts, without the second plurality of receptacles 194. In particular, in some embodiments the end user (not shown) is able to drill or otherwise form holes into the second perforation plate 152 as desired. In some embodiments, the second perforation plate 152 is formed of a material that is amenable to machining by an end user (e.g., appropriate polymeric material, such as those sold under the trade name “DELRIN”).
The first and second slider lumens 198, 200 are optionally substantially similar, extending substantially parallel to one another through the body 190 under the upper surface 192.
The first and second sliders 154, 156 are optionally substantially similar. In some embodiments, the first and second sliders 154, 156 are formed of a cylindrical rod material (e.g., steel stock material). In some embodiments, the first slider 154 is adapted to be received in the first slider lumens 178, 198 and the second slider 156 is adapted to be received in the second slider lumens 180, 200, as subsequently described. Each of the first and second sliders 154, 156 defines a central longitudinal axis X154, X156, respectively.

In some embodiments, the second perforation plate 152 is aligned to the second handle 28, and in particular the second pivot receptacle 196 of the second perforation plate 152 to the second receptacle 90 in the second handle 28 and securing the second pivot fastener 158 through the second receptacle and into the second pivot receptacle 196 to define a second jaw pivot P160 about which the second perforation plate 152 pivots. The second jaw pivot P160 is located distal the handle pivot P20 according to some embodiments. Upon assembly, the first and second perforation plates 150, 152 are pivotably secured to the first and second handles 26, 28, respectively. Additionally, the first and second perforation plates 150, 152 are slidably connected to one another via the first and second sliders 156, 158.
The distal portions 58, 88 of the first and second handles 26, 28 help provide means for restraining the relative lateral movement of the forming pegs to a first line of action. In some cases the means for restraining the relative lateral movement of the forming pegs to a substantially straight line of action includes the first and second sliders 156, 158.
Upon actuation of the proximal portions 54, 84 of the first and second handles 26, 28 the distal ends 52, 82 move along the substantially curved first line of action A20 (
In some methods of forming a workpiece (
As shown in
In some embodiments, assembly of the tool 320 generally proceeds similarly to that of the first tool 20. In comparison to the tool 20, however, the first and second handles 326, 328 of the tool 320 cross one another at the axis of rotation P320 such that upon actuating the handles 326, 328 toward one another at the proximal end 322 of the tool 320, the first and second perforation plates 450, 452 are moved toward one another along a substantially straight line of action A320. Thus, the tool 320 is optionally used to grasp objects (not shown) between the first and second perforation plates 450, 452 and/or to grasp objects between an array of forming pegs (not shown) releasably received in the perforation plates 450, 452.
The seventh forming peg pair 514 includes a first forming peg 514A and a second forming peg 514B, the forming pegs 514A, 514B optionally being substantially similar.

The lower portion 520A is configured to be received in the receptacles 70, 100 and/or the perforation plates 150, 152 while the upper portion 522A is formed to a desired shape and/or diameter (e.g., the upper portion 522A is substantially cylindrical and ½ inch in diameter in one example). In some embodiments, the upper portions of the forming peg pairs 502, 504, 506, 508, 510, 512, 514 and the first and second forming pegs 42, 44, graduate in diameter. For example, the first and second forming peg pairs optionally graduate from about 1/16 inches to about ½ inches in diameter in 1/16 inch increments. As shown, in some embodiments, the lower portions of the forming peg pairs are substantially similar in size and shape (e.g., ⅛ inch in diameter) and configured to be received in the receptacles 70, 100 and/or the perforation plates 150, 152. In some embodiments, the first pair 502 is about 1/16 inches, the first and second forming pegs 42, 44 are about ⅛ inches, the second pair 504 is about 3/16 inches, the third pair 506 is about ¼ inches, the fourth pair 508 is about 5/16 inches, the fifth pair 510 is about ⅜ inches, the sixth pair 512 is about 7/16 inches, and the seventh pair 514 is about ½ inches at the upper portions thereof, respectively.

As another example, the first forming peg pair 502 includes a first forming peg 502A and a second forming peg 502B, the forming pegs 502A, 502B optionally being substantially similar. The first forming peg 502A has a lower portion 530A and an upper portion 532A. The lower portion 530A has a central longitudinal axis X530A and the upper portion has a central longitudinal axis X532A. The axes X530A, X532A are substantially parallel, but are laterally offset from one another, or eccentric to one another.
In some embodiments, assembly of the tool 320 generally proceeds similarly to that of the first tool 20. In comparison to the tool 20, however, the first and second handles 326, 328 of the tool 320 cross one another at the axis of rotation P320 such that upon actuating the handles 326, 328 toward one another at the proximal end 322 of the tool 320, the first and second perforation plates 450, 452 are moved toward one another along a substantially straight line of action A320. Thus, the tool 320 is optionally used to grasp objects (not shown) between the first and second perforation plates 450, 452 and/or to grasp objects between an array of forming pegs (not shown) releasably received in the perforation plates 450, 452.
The first mounting arm 664 is optionally secured, or attached, to the base 649 (e.g., via welding, screws, bolts, or other fastening means). The second mounting arm 666 is optionally slidably received against the base 649. In some embodiments, the second mounting arm 666 slides against the surface of the base 649 and moves in a substantially linear, parallel relationship with the first mounting arm 664. If desired, the second mounting arm 666 is adapted to slide on a track (not shown) secured to the base 649, or is otherwise slidably secured relative to the base 649.
The actuation means 625 is attached to the first mounting arm 664 in some embodiments, and comprises an actuator 626 (also described as an actuation portion), such as a pneumatic drive, hydraulic drive, electric motor drive, or other actuator for providing a forming force. The actuation means 625 also includes an elongate drive arm 634 (also described as a drive portion) that is attached to the second mounting arm 666. In some embodiments, the actuation means also includes an actuating lever 628 for controlling operation of the actuator 626, where depressing the actuating lever 628 extends the drive arm 634 to a maximum distance that is determined by the adjustable travel stop 636. When the actuating lever 628 is released, the drive arm 634 retracts to its beginning position. In some embodiments, the actuating lever 628 can be replaced by a foot pedal, or electric, pneumatic, hydraulic, or digitally controlled valves to regulate and control movement of the drive arm 634.
In some embodiments, the first perforation plate 750 is substantially similar to the first perforation plate 150, the first perforation plate 750 including a body 770 that is substantially block- or plate-shaped and having an upper surface 772. The body 770 has a first plurality of receptacles (not shown), also described as peg apertures, formed into the upper surface 772. The body 770 also has a first slider lumen 778 for receiving the first slider 754. In some embodiments, the body 770 has a second slider lumen (not shown) for receiving a second slider (not shown).
In some embodiments, the second perforation plate 752 is substantially similar to the second perforation plate 152, the second perforation plate 752 including a body 790 that is substantially block- or plate-shaped and has an upper surface 792. The body 790 has a second plurality of receptacles (not shown), also described as peg apertures, formed into the upper surface 792. The body 790 also has a first slider lumen 798 for receiving the first slider 754. In some embodiments, the body 790 has a second slider lumen (not shown) for receiving a second slider (not shown).
The first and second perforation plates 750, 752 are optionally used in operations similar to those described in association with the tools 20, 320. For example, pegs (not shown) are optionally inserted into the perforation plates 750, 752. The actuator 626 is optionally operated to apply a forming force that causes the first and second perforations plates 750, 752 to move away from one another along a substantially linear path in a forming (e.g., including bending and/or grasping) operation with a workpiece (not shown) received over and/or between the pegs.
The mounting arms 664, 666 help provide a means for restraining the relative lateral movement of the forming pegs. In some cases the means for restraining the relative lateral movement of the forming pegs to a first, substantially straight line of action includes the first slider 754 and, optionally, second slider. In some embodiments, the adjustable travel stop 636 also restrains the lateral movement of the forming pegs to a desired range of motion.
The second mounting arm 866 is threaded to accept the threaded rod 826. The threaded rod 826 is threaded through the second mounting arm 866 and affixed to the first mounting arm 864. As a forming force is applied, the threaded rod 826 is turned about axis X826, the second mounting arm 866 can move back and forth along line of action A920. The adjustable travel stop 836 determines how far the movable mount 866 moves along the mounting fixture 848.
In some embodiments, a handle crank 828 (also described as an actuation portion or actuation arm) is attached to the threaded rod 826 for application of a forming force by a user (not shown). In some embodiments, a forming force is applied to the threaded rod 826 via an actuation portion comprising an electric motor or rack and gear powered by an air cylinder or hydraulic cylinder. In some embodiments, the rotation of the threaded rod 826 can be controlled or regulated by foot pedal, electric, pneumatic, hydraulic, or digitally controlled relays and valves.

In some embodiments, a lever 1028 is attached to the shaft-mounted gear 1110 such that applying a forming force to the lever 1028 rotates the gear 1110. The teeth 1112 on the gear 1110 engage the rack 1026 to move the second mounting arm 1066 back and forth along the line of action A1120. In some embodiments, the adjustable travel stop 1036 determines how far the second mounting arm 1066 moves along the mounting fixture 1048.
In some embodiments, forming force is applied to the gear 1110 via an electric motor or rack and gear (not shown) powered by an air cylinder or hydraulic cylinder. In some embodiments, the rotation of the gear 1110 can be controlled or regulated by foot pedal, electric, pneumatic, hydraulic, or digitally controlled relays and valves.
In some embodiments, a rack 1026 and gear 1110 arrangement is affixed to the perforation plates 1150, 1152. A rack 1026 is affixed to the first perforation plate 1150 and a forming gear 1110 is affixed to the second perforation plate 1152. The rack 1026 is affixed to the first perforation plate 1150 so as to be able to pivot at pivot receptacle 1060. A compression spring 1034 pushes on the rack 1026 to engage the gear 1110. As the perforation plates 1150, 1152 move back and forth in a line of action A1120, the gear 1110 rotates. The gear 1110 comprises a form 1042 designed with a geometric shape. A retention peg 1114 holds a wire W20 against the form 1042 as the gear 1110 rotates, such that the wire W20 is bent around the form 1042 to form shapes. In some embodiments, an adjustable tensioning device (not shown) is affixed to the first perforation plate 1150 to keep the wire W20 taut as it is being formed.
In some embodiments, a lever (not shown) is attached to the forming gear 1110 such that moving the lever rotates the gear 1110. In other embodiments, the forming gear 1110 incorporates a one-way bearing or ratchet mechanism (not shown) to accommodate wire forms that require multiple linear cycles to achieve the desired form.
The foregoing examples provide a description of tools, tool kits, and associated methods. The tools are suited to interchangeably maintain forming pegs or forming gears and, in some embodiments, include perforation plates and sets of forming pegs or forming gears of varying configurations, which are optionally supplied as a kit of parts to a user or other recipient. The tools provide versatile solutions to forming and/or clasping needs associated with, for example, jewelry making activities.
Although various features have been described in association with example embodiments, such features are interchangeable (e.g., as additional or alternate feature) between the various examples provided herein—while the embodiments described above refer to particular features, the scope of this invention also includes embodiments having different combinations of features and embodiments that do not include all of the described features. Similarly, various modifications and additions can be made to the exemplary embodiments discussed without departing from the scope of the present invention. Accordingly, the scope of the present invention is intended to embrace all such alternatives, modifications, and variations as fall within the scope of the claims, together with all equivalents thereof.
This application claims the benefit under 35 U.S.C. §119 of U.S. Provisional Application No. 61/235,501, filed on Aug. 20, 2009, entitled “Hand Tools and Associated Methods,” which is incorporated herein by reference in its entirety for all purposes.
