The present specification relates generally to tools, and more particularly to cutting tools.
Fishermen use a variety of equipment when they fish. For instance, a fisherman may carry a tackle box or a vest holding a wide variety of flies, hooks, and other devices to be attached to a line. The fisherman might have a small guidebook describing the creek, lake, or other water which he is fishing, or the type of lure and line to be used for a fish feeding in a certain location. The fisherman will likely also carry a variety of lines with him, because he may use numerous lines of varying weights while fishing. In sum, the fisherman carries a great deal of gear. The fisherman often keeps all his gear together so that none of it is forgotten or lost, but keeping and storing it together reduces its portability and is cumbersome.
In addition to all his other gear, the fisherman typically also carries at least one knife and a pair of small scissors or snips. Booth tools can be useful in a number of expected and unexpected ways. Frequently, though, they are used to cut line, perhaps because the line is tangled, about to be tied to a leader or tippet, needs to be freed of a hook, or for other reasons. The fisherman thus frequently pulls his knife or snips out, cuts the line, and then stows the tool. When the fisherman uses his sharp tools over and over, despite the best of intentions, he can grow cavalier, and they can pose a severe danger to himself and others. Further, if the fisherman needs the immediate ability to cut the line without hesitation, he may not have time to reach to his knife or snips. Still further, if the fisherman forgets or loses his knife or snips, he has to resort to especially crude methods for cutting the line, such as using his teeth or a rock, if cutting the line is at all possible.
Quilters, sewers, and others who work with threads and fine fabrics have similar problems. They, too, face a cut risk from the tools they use to cut threads and fine fabrics. An improved device for cutting fishing line, thread, and other fine lines and fabrics is needed.
A cutting and snipping device includes a housing having a front, an opposed rear, an open mouth at the front, opposed sides extending from the front to the rear and each formed with longitudinal slots, and a head projecting from the rear, wherein a blade set into the head is exposed between the head and the rear of the housing. The device includes scissor arms, each having a cutting edge at a front end, an opposed rear end, and a grip extending between the front end and the rear end. The scissor arms are mounted within the housing for scissored movement with respect to each other and for reciprocal movement with respect to the housing between a forward position in which the cutting edges are advanced out of the mouth and a retracted position in which the cutting edges are retracted within the mouth.
The above provides the reader with a very brief summary of some embodiments described below. Simplifications and omissions are made, and the summary is not intended to limit or define in any way the disclosure. Rather, this brief summary merely introduces the reader to some aspects of some embodiments in preparation for the detailed description that follows.
Referring to the drawings:
Reference now is made to the drawings, in which the same reference characters are used throughout the different figures to designate the same elements. Briefly, the embodiments presented herein are preferred exemplary embodiments and are not intended to limit the scope, applicability, or configuration of all possible embodiments, but rather to provide an enabling description for all possible embodiments within the scope and spirit of the specification. Description of these preferred embodiments is generally made with the use of verbs such as “is” and “are” rather than “may,” “could,” “includes,” “comprises,” and the like, because the description is made with reference to the drawings presented. One having ordinary skill in the art will understand that changes may be made in the structure, arrangement, number, and function of elements and features without departing from the scope and spirit of the specification. Further, the description may omit certain information which is readily known to one having ordinary skill in the art to prevent crowding the description with detail which is not necessary for enablement. Indeed, the diction used herein is meant to be readable and informational rather than to delineate and limit the specification; therefore, the scope and spirit of the specification should not be limited by the following description and its language choices.
Referring now also to
The housing 11 has a front 23 and an opposed rear 24. In this disclose, directions, orientations, and arrangements of the device 10 are generally made with reference to this front 23 and rear 24. For example, if the description states that a feature is in front of an element, it should be understood that the feature is closer to the front 23 than is the element. An interior 40 of the housing 11 extends and is defined between the front 23 and the rear 24. A mouth 25 is formed at the front 23. The mouth 25 is open, a concave notch formed into the housing 11 and in communication with the interior 40 thereof. The scissor arms 12 and 13 partially extend through the mouth 25, and they are disposed as such in order to reciprocate and move in pivotal or scissored movement in the mouth 25, as is explained further below. A decorative cover 15 is adhered to the top housing 20.
Opposed sides 26 and 27 extend between the front 23 and rear 24 of the housing 11. The sides 26 and 27 are arcuate, bowing outwardly from the interior 40 in a convex arrangement. Sides 26 and 27 begin at the front 23 at the mouth 25 and extend rearwardly to terminate at shoulders 30 and 31. The housing 11 thus progressively enlarges from the mouth 25 toward the shoulders 30 and 31. The shoulders 30 and 31 are short, small projections extending laterally outward at the rear 24 of the housing 11 from the sides 26 and 27.
Just behind the shoulders 30 and 31 are decks 32 and 33. The decks 32 and 33 are slightly curved, extending laterally inwardly from the shoulders 30 and 31 to a neck 34 of the housing 11. The neck 34 is a thin extension of the housing 11, aligned between the front 23 and rear 24, which connects a head 35 of the device 10 to the rear 24 of the housing 11.
The head 35 projects from the rear 24 of the housing 11. The head 35, in this embodiment, is approximately triangular. It has a wide base opposite the rear 24 of the housing 11. As such, a gap 36 is defined between the head 35 and the rear 23 on both sides of the neck 34. Edges of the blade 14 are exposed in these gaps 36. The head 35 includes a hole 36 through which a lanyard or other leash can be run to attach the device 10 to a vest, article of clothing, or other item.
Reference is now made primarily to
A thin slot 41 is formed at the mouth 25. The slot is cooperatively defined by two coextensive and opposing recesses formed into otherwise-mating surfaces of the top and bottom housings 20 and 21. In other embodiments, the slot 41 is defined by a recess formed into only one of the mating surfaces of the top and bottom housings 20 and 21. The slot 41 is aligned between the sides 26 and 27 but does not extend so far: its width is confined by the mouth 25. Indeed, two opposed endwalls 49, marking the beginning of the sides 26 and 27 at the front 23, bound both the mouth 25 and the slot 41. The front ends of the scissor arms 12 and 13 extend through this slot 41.
There are also elongate slots 42 and 43 which extend in and along the sides 26 and 27. The slots 42 and 43 are formed cooperatively from two coextensive and opposing recesses in the mating surfaces of the top and bottom housings 20 and 21. The slots 42 and 43 extend longitudinally, entirely from the endwalls 49 at the mouth 25 to the shoulders 30 and 31 proximate the rear 24 of the housing 11. These slots 42 and 43 accommodate handles of the scissor arms 12 and 13, respectively.
Behind the track 45 are two posts 50 formed integrally and monolithically to the top housing 20. The posts 50 extend downward from the top housing 22 are and received in complemental sockets 51 formed integrally and monolithically into the bottom housing 22 and extending upward therefrom.
Just in front of the decks 32 and 33, proximate to the shoulders 30 and 31, are two chocks 52 and 53 enclosed within the interior 40. While the posts 50 are preferably cylindrical, the chocks 52 and 53 are preferably rectangular. The posts 50 are both closer to the front 23 of the housing 11 than are the chocks 53 and 53. The chocks 52 and 53 are formed integrally and monolithically to the top and bottom housings 20 and 21 to form the set of chocks 52 and 53 entirely through the vertical extent of the interior 40. The chocks 52 and 53 are spaced apart from each other and are each formed proximate to and integrally to the rear 24 of the housing 11 as an integral, monolithic, non-separate portion of the housing 11. The chocks 52 and 53 are also proximate the opposing sides 26 and 27.
Turning now primarily to
The arms 12 and 13 are shown in
When carried within the interior 40, the arm 12 is mounted onto the post 48 of the guide 46. A hole 71 through the handle 61, just behind the blade 60, accommodates the post 48. A second hole 72 is formed behind the hole 71. This second hole 72 receives legs of a spring which biases the scissor arms 12 and 13 apart, as will be described. The inner side 67 of the blade contours around the hole 72; the inner side 67 extends inwardly at a notch 73 proximate the hole 72, a bump 74 then projects outwardly from the behind the notch 73, and then the inner side 67 cuts inward and extends backward to form a large open corner 75 proximate the rear end 66. The rear end 66 of the arm 12 is generally transverse to a line extending from the front end 65 to the rear end 66. A notch 76 is formed into the rear end 66 of the arm 12; the notch 76 is a rectangular recess with two approximately right-angled corners. The notch 76 is sized and shaped to receive the chock 53 stop means in certain positions of the arm 12.
When carried within the interior 40, the arm 12 extends through the slot 41 in the mouth 25 and through the slot 43 in the side 27. The upstanding grip 70 is larger than the slot 43. It is disposed outside the slot 43, such that it cannot be moved through the slot 43. As such, when the arm 12 moves in either reciprocal or scissored movement, the grip 70 remains outside the housing 11, where the user's fingers can hold and manipulate it. The blade 60 is positioned within the slot 41. The blade 60 is thin, and smoothly moves through the slot 41 between retracted and advanced positions with respect to the mouth 25.
Again, the arm 13 is nearly the mirror identical of the arm 12. The arm 12 overlies the arm 13 when carried in the housing 11; indeed, the arm 12 slides directly on top of the arm 13 during pivotal movement of the arms 12 and 13. The arm 13 includes a front end 85 and an opposed rear end 86, and a forward blade 80 at the front end 85 and an opposed rearward handle 81 at the rear end 86. The blade 80 and handle 81 are delineated approximately by the broken line marked with the reference character C in
When carried within the interior 40, the arm 13 is mounted onto the post 48 of the guide 46. A hole 91 through the handle 81, just behind the blade 80, accommodates the post 48. A second hole 92 is formed behind the hole 91. This second hole 92 receives legs of a spring that biases the scissor arms 12 and 13 apart, as is described below. The inner side 87 of the blade 61 contours around the hole 92; the inner side 87 extends inwardly at a notch 93 proximate the hole 92, a bump 94 then projects outwardly from the behind the notch 93, and then the inner side 87 cuts inward and extends backward to form a large open corner 95 proximate the rear end 86. The rear end 86 of the arm 13 is generally transverse to a line extending from the front end 85 to the rear end 86. A notch 96 is formed into the rear end 86 of the arm 13; the notch 96 is a rectangular recess with two approximately right-angled corners. The notch 96 is sized and shaped to receive the chock 53 stop means in certain positions of the arm 13.
When carried within the interior 40, the arm 13 extends through the slot 41 in the mouth 25 and through the slot 42 in the side 26. The upstanding grip 90 is larger than the slot 42 and is disposed outside the slot 42, such that it cannot be moved through the slot 42 into the interior 40. As such, when the arm 13 moves in either reciprocal or scissored movement, the grip 90 remains outside the housing 11, where the user's fingers can hold and manipulate it. The blade 80 is positioned within the slot 41. The blade 80 is thin and smoothly moves through the slot 41 between retracted and advanced positions with respect to the mouth 25.
Turning now to
Moreover, the open corners 75 and 95 of the arms 12 and 13 interact with the posts 50 within the housing 11. The open corners 75 and 95 are sized and shaped to receive both of the posts 50; the open corners 75 and 95 have a length corresponding to the combined diameters of the two posts 50. Further, when the arms 12 and 13 are in the closed position thereof, the open corners 75 and 95 are spaced apart from each other by the posts 50. The posts 50 act as stops to the arms 12 and 13; preventing, by contact therewith, the arms 12 and 13 from overlapping too far. The width of the arms 12 and 13 (between the inner and outer sides 67 and 68 and inner and outer sides 87 and 88, respectively) is such that, when the arms 12 and 13 are in the closed position and the inner sides 67 and 87 are received against the posts 50, the upstanding grips 70 and 90 are just outside the slots 42 and 43, such that the grips 70 and 90—each arcuate—are registered with and registered along the arcuate sides 26 and 27.
When the device 10 is arranged as shown in
Indeed, each chock 52 and 53 prevents both arms 12 and 13 from pivoting. For example, the chock 52 directly engages the notch 96 of the arm 13, thereby preventing the arm 13 from scissored movement. Because the arms 12 and 13 are coupled to each other at the post 46, the arm 12 is prevented from moving forward so long as the arm 13 is held in place. Therefore, so long as the arm 13 is in the retracted position and is engaged with the chock 52, the arm 12 cannot scissor either. The same is true if the arm 12 is engaged with the chock 53.
In this manner, in the closed position of the arms 12 and 13, the arms 12 and 13 are securely held, and inadvertent opening of the arms 12 and 13 is mitigated. The blades 60 and 80 are retracted, such that a portion of the blades 60 and 80 are behind the mouth, and only the very front ends 65 and 85 of the arms 12 and 13 extend beyond the endwalls 49 of the housing 11. The cutting edges 62 and 82 are within the mouth 25 and overlap each other.
When the arms 12 and 13 are in the retracted position thereof, the guide 46 is against the rear portion of the oval sidewall 44 defining the track 45. As noted above, the post 48 of the guide passes through the holes 71 and 91 of the arms 12 and 13. When the arms 12 and 13 are in the device, these holes 71 and 91 are registered and aligned with each other, such that the arms 12 and 13 pivot about the common post 48.
When a person wants to use the snips, he takes his thumb and finger and places them against the grips 70 and 90. He moves the grips 70 and 90 forward. The arms 12 and 13 thus move forward, pushing the post 48 of the guide 46 forward as well. The guide 46 slides forwardly in the track 45; it cannot move in any other direction, and so the arms 12 and 13 are limited in their reciprocal movement in a forward direction from the initial rearward disposition of the guide 46. The user pushes the arms 12 and 13 forward until the base 47 of the guide 46 encounters the front of the sidewall 44 and prevents further forward movement. When the guide 46 is moved fully forward, the arms 12 and 13 are in the advanced position, as shown in
To use the device 10 to snip, the user now releases his hold slightly on the grips 70 and 90, and the spring 100 biases the arms 12 and 13 apart. The arms 12 and 13 swing in scissored movement, apart from each other and away from the sides 26 and 27 of the housing 11, along the arcuate lines shown in
The user places a thread, line, or other fabric or material between the edges 62 and 82 and then squeezes the grips 70 and 90 together. This causes the blades 60 and 80 to close, thereby cutting the material between the edges 62 and 82. If additional snips are required, the user cyclically releases and squeezes the grips 70 and 90 according to conventional scissor use. When no further snips are required, the user squeezes the grips 70 and 90 together and then applies force on them in a rearward direction. This aligns and registers the notches 96 and 76 with the chocks 52 and 53 and causes the grips 70 and 90 and the arms 12 and 13 to slide backward. The arms 12 and 13, mounted on the post 48 of the guide 46, impart rearward movement of the guide 46 within the track 45 until the guide 46 is stopped at the rear of the track 45. The notches 96 and 76 are moved over the chocks 52 and 53, respectively, which are sized and shaped complementally. The chocks 52 and 53, having a rectangular shape, prevent inadvertent movement of the arms 12 and 13 outward away from each other, thereby locking the arms 12 and 13 in place in the retracted or stowed position, shown in
The device 10 also includes the blade 14 carried in the head 35. The blade 14 is carried between the top and bottom housing 20 and 21, secured there by two pins 106 through the head 35 and the blade 14. A cutting edge 108 of the blade 14 is revealed in the opposed gaps behind the decks 32 and 33 and in front of the head 35. Fishing line, thread, or other items can be drawn into either of these gaps and then pulled so as to be drawn against the cutting edge of the blade 14, thereby cutting the item.
The device 10 also includes a clip 107 on the bottom housing 21 to allow the device 10 to be secured to pockets and articles of clothing. The clip 107 is constructed from a resilient spring metal or plastic and includes a long arm extending along the bottom housing 21 between the shoulders 30 and 31 and the mouth 25.
A preferred embodiment is fully and clearly described above so as to enable one having skill in the art to understand, make, and use the same. Those skilled in the art will recognize that modifications may be made to the description above without departing from the spirit of the specification, and that some embodiments include only those elements and features described, or a subset thereof. To the extent that modifications do not depart from the spirit of the specification, they are intended to be included within the scope thereof.
