DETAILED DESCRIPTION

(18) FIG. 1 illustrates an embodiment of a cutting apparatus 10 that incorporates teachings of this disclosure. The illustrated cutting apparatus 10 includes a top 12 and a base 16, which are configured to be at least partially assembled with and disassembled from one another. More specifically, the top 12 may be configured to be positioned over and assembled with the base 16 to define a closed arrangement between the top 12 and the base 16. In addition, the top 12 may be configured to be removed from or spaced apart from the base 16 to provide an open arrangement of the top 12 and the base 16. In some embodiments, a hinge 18 (FIGS. 3 and 7) may secure corresponding edges of the top 12 and the base 16 to one another to facilitate movement of the top 12 between the closed position over the base 16 and the open position relative to the base 16.

(19) With reference to FIGS. 2 through 6, an embodiment of the top 12 of a cutting apparatus 10 is described in further detail. The top 12 may include an upper surface 20 and an opposite engagement portion 21. The upper surface 20 may define at least a portion of an upper surface of the cutting apparatus 10, while the engagement portion 21, and a retention surface 30 thereof, may be configured to face the base 16 of the cutting apparatus 10 when the top 12 is placed over the base 16 in the closed arrangement.

(20) The engagement portion 21 of the top 12 may define a recess 22. As depicted in FIG. 5, the recess 22 may be elongated in configuration and be arranged centrally relative to the retention surface 30 into which the recess 22 extends (e.g., between elongated, spaced apart sections of the retention surface 30, etc.). An aperture 15 may extend between the recess 22 and the upper surface 20 of the top 12. Together, the aperture 15 and the recess 22 may accommodate certain other components of the top 12.

(21) Among other components, the top 12 may include a button 14 with an external portion 14E and an internal portion 141. The external portion 14E of the button 14 may extend through the aperture 15 and protrude from the outer surface 20 of the top 12, where the external portion 14E of the button 14 may be accessed and depressed when use of the cutting apparatus 10 is desired.

(22) The internal portion 141 of the button 14 may be located within the recess 22. As depicted, the internal portion 141 may include a pair of spaced apart arms 27 that extend generally away from the upper surface 20 of the top 12. A wire 28 may extend from one arm 27 to the other, and be positioned at an elevation that causes the wire 28 to remain within the recess 22 when the button 14 is in its non-operational original position, but enables the wire 28 to be moved downwardly out of the recess 22 as the external portion 14E of the button 14 and, thus, the button 14 is depressed, or placed in an operational position.

(23) The top 12 may also include means for resiliently moving the button 14 back to its original position once its external portion 14E is released. In a specific embodiment, shown in FIG. 4, one or more springs 29 may be associated with the internal portion 141 of the button 14 in a manner that urges the button 14 toward its original position.

(24) As FIGS. 3 and 4 illustrate, the top 12 may also include other features, such as the depicted switch 23 (e.g., a two position sliding switch, etc.) and indicator light 24 (e.g., a light-emitting diode lamp, etc.), which are associated with an electrical circuit of which the wire 28 and a power source 46 (FIG. 8) is also a part. The wire 28 may comprise an electrically conductive material with sufficient resistance to heat up to a desired temperature as the switch 23 is placed in a position that completes the electrical circuit and the power source 46 applies a current to the wire 28.

(25) In some embodiments, the top 12 of a cutting apparatus 10 may also include a safety mechanism. In some embodiments, a safety mechanism may prevent depression of the button 14 if the top 12 and the base 16 are not in the closed arrangement, but enable depression of the button 14 if the top 12 and the base 16 are in the closed arrangement. In addition, or alternatively, a safety mechanism may be configured to enable operation of the heating element only when the top 12 and the base 16 are in the closed arrangement.

(26) Turning now to FIGS. 7 through 10, an embodiment of the base 16 of a cutting apparatus 10 is illustrated.

(27) As shown in FIG. 7, the base 16 includes a support surface 34 against which the retention surface 30 of the top 12 (FIG. 6) is configured to be positioned. At least a portion of the support surface 34 may have a contour that complements a contour of a corresponding portion of the retention surface 30 of the top 12, which may enable these portions to contact each other when the top 12 and the base 16 are placed in the closed arrangement. In the depicted embodiment, the support surface 34 of the base 16 and the retention surface 30 of the top 12 are both flat.

(28) With continued reference to FIG. 7 and returned reference to FIG. 6, one or both of the retention surface 30 of the top 12 and the support surface 34 of the base 16 may be configured to hold an elongate element in place while the top 12 and the base 16 are in the closed arrangement with the elongate element positioned between the retention surface 30 and the support surface 34, and as a downward force on (i.e., depression of) the button 14 (see, e.g., FIG. 4) forces the wire 28 (see, e.g., FIG. 4) against the elongate element. In some embodiments, one or both of the retention surface 30 and the support surface 34 may comprise (e.g., be coated with, be formed from, etc.) an engagement material 32 and 36, respectively, that holds the elongate element in place. Such an engagement material 32, 36 may be tacky, compliant or have another property that enables it to engage the elongate material. In a specific embodiment, one or both of the retention surface 30 and the support surface 34 may comprise silicone. In addition, or as an alternative, one or both of the retention surface 30 and the support surface 34 may include a texture 33 and 37, respectively, that holds the elongate element in place.

(29) In some embodiments, such as those illustrated by FIGS. 7A and 7B, the support surface 34 of an engagement portion 16A of the base 16 may include alignment features 35, 35, which may facilitate placement of an elongate element on the support surface 34 and, thus, its alignment with the wire 28 (FIG. 4). In various embodiments, the alignment features 35, 35 may include horizontal elements and vertical elements. The alignment features 35 may also include diagonal elements.

(30) Again referring to FIG. 7, in addition to the support surface 34, the engagment portion 16A of the base 16 includes an elongated receptacle 38 recessed in a central region of the support surface 34 (e.g., between spaced apart elongated sections of the support surface 34, etc.). The receptacle 38 may be configured to receive and accommodate the wire 28 (FIG. 4) and the arms 27 of the internal portion 141 of the button 14 (FIG. 4) (or at least the lowermost portions thereof) when the button 14 is depressed. In addition, as depicted by FIG. 7B, an indicator 40, such as the depicted line, may be provided in the bottom of the receptacle 38 to show where the wire 28 will intersect an elongate element positioned over the support surface 34.

(31) The base 16 may also define a receptacle 45 for a power supply 46 (e.g., four AA batteries, etc.). In the embodiment depicted by FIGS. 7 through 9, the base 16 includes an engagement portion 16A and a lower portion 16B that are ordinarily assembled with one another (e.g., while the cutting apparatus 10 is being used, during storage of the cutting apparatus 10, etc.), but may be disassembled from one another to provide access to the receptacle 45, such as when access to the power supply 46 is desired (e.g., for replacement, etc.). Alternatively, as illustrated by FIG. 10, access to the receptacle 45 within the base 16 may be obtained through an access panel 44 (e.g., a sliding access panel, another type of battery cover, etc.) at the bottom surface 42 of the lower portion 16B of the base 16.

(32) Various embodiments of methods for using the cutting apparatus 10 are also disclosed. In FIGS. 11 through 14, an embodiment of a method for forming a substantially linear cut through an elongate element 50 is depicted. FIGS. 15 through 18 illustrated an embodiment of a technique for forming a V-shaped cut through an elongate element 50.

(33) As shown in FIG. 11, the top 12 of a cutting apparatus 10 may be at least partially spaced apart from the base 16 of the cutting apparatus 10 to expose a support surface 34 of the base 16. An elongate element 50 that is to be cut, such as the depicted ribbon, may be placed on and supported by the support surface 34. In some embodiments, one or more alignment features 35, 35 (FIGS. 7A and 7B, respectively) and/or another indicator 40 (FIG. 7B) may be used to guide placement of the elongate element 50 on the support surface 34.

(34) With the elongate element 50 positioned as desired on the support surface 34, the top 12 of the cutting apparatus 10 may be positioned against the base 16, as shown in FIG. 1. In this closed arrangement, the retention surface 30 (FIG. 11) of the top 12 and the support surface 34 (FIG. 11) of the base 16 may hold the elongate element 50 in place.

(35) The wire 28 (FIG. 4) may be heated as power is supplied to the wire 28. In the illustrated embodiment, power may be supplied to the wire 28 by moving the switch 23 to an on position. Once the wire 28 has heated to a sufficient temperature (which may occur within a matter of seconds (e.g., about five seconds or less, etc.) of supplying power to the wire 28), it may be used to cut the elongate element 50 and, when the elongate element 50 includes a material that may be seared or melted, seal the cut ends 52A and 52B (FIG. 13) of the elongate element 50.

(36) As depicted by FIG. 12, slight depression of the button 14 in the top of the cutting apparatus 10 may force the top 12 against the base 16 (FIG. 11) and, thus, hold the elongate element 50 in place between the top 12 and the base 16. Further depression of the button 14 may bring the heated wire 28 (FIG. 4) into contact with the elongate element 50. As disclosed previously herein with reference to FIG. 7, such further depression of the button 14 may cause the wire 28 to move from a first position within a recess 22 in the top 12 of the cutting apparatus 10, or a location above (or on a first side of) the elongate element 50, to a second position within a receptacle 38 (FIGS 7 and 13) in the engagement portion 16A (FIGS. 7-7B) of the base 16 of the cutting apparatus 10, or a location beneath (or on a second side of) the elongate element 50. As the heated wire 28 contacts and is forced through a portion of the elongate element 50 that extends over the receptacle 38 in the base 16, the heated wire 28 cuts and, in some embodiments, seals the newly cut ends 52A and 52B (FIG. 13) of the elongate element 50.

(37) Once the elongate element 50 has been cut, the button 14 may be released, enabling the button 14 and the wire 28 to return to their original positions. As illustrated by FIG. 13, the top 12 may then be at least partially removed from the base 16 of the cutting apparatus 10, and the cut sections 50A and 50B of the elongate element 50 may be removed from the support surface 34 of the base 16.

(38) In a variation of the process depicted by FIGS. 11 through 13, FIGS. 14 through 17 illustrate a process in which a V-shaped cut may be formed in an elongate element 50. As illustrated by FIG. 14, a portion 54 of the elongate element 50 may be folded along its length, then positioned somewhat diagonally relative to the support surface 34 of the base 16 of a cutting apparatus 10. While that portion 54 of the elongate element 50 remains folded, a top 12 of the cutting apparatus 10 may be positioned against the base 16, as shown in FIG. 15, holding the elongate element 50 in place and maintaining its folded orientation. With the wire 28 (FIG. 4) heated to a sufficient temperature, an individual may depress the button 14 in the top 12 of the cutting apparatus 10, as shown in FIG. 16, forcing the hot wire 28 through and cutting (and, in some embodiments, sealing) the folded portion 54 of the elongate element 50. Once the elongate element 50 has been cut, the button 14 may be released and, along with the wire 28, allowed to return to its original position. Additionally, as shown in FIG. 17, the top 12 may be at least partially removed from the base 16 to enable removal of the cut sections 50A and 50B from the cutting apparatus 10. As the cut sections 50A and 50B are unfolded at their respective cut ends 52A and 52B, the V shapes of the cut ends 52A and 52B are revealed.

(39) By holding the elongate element in a desired orientation while confining movement of the wire 28 (or any other embodiment of cutting element), the cutting apparatus 10 may be used to cut an elongate element 50 without repeated effort. In addition, the use of a heated wire 28 to cut through an elongate element 50 may seal the newly cut edges 52, which may prevent fraying of the edges 52.

(40) The disclosed embodiments should not be deemed to limit the scope of any of the claims that follow. The scope of each claim should be limited merely by its plain language, and should be deemed to include the full complement of available equivalents.
