The first and second surfaces each contain at least one magnet have a polarity such that the magnets repel.

Description

BACKGROUND

Nippers, sometimes known as end cutters or end cutting pliers, are used by fishermen to assist in preparing a hook and line for fishing. The conventional nipper typically comprises a pivotal jaw with a sharp blade on one side and handles or levers on the other side to transmit a pinching force to the sharp blade to facilitate the cutting or nipping of the line, hook, lure, or the like.

Conventionally, nippers are provided with removable blades that are sharp. The removable blade allows for each or both blades to be replaced. The blade needs to be replaced as the metal of the blade both dulls and corrodes over time due to use and exposure.

However, present nippers are small and difficult to keep track of while fishing. Additionally, the blade wear and corrosion can make the effectiveness of the nippers poor requiring more force and, sometimes, repetition.

Thus, against the above background, an improved nipper assembly would be desirous.

SUMMARY

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary, and the foregoing Background, is not intended to identify key aspects or essential aspects of the claimed subject matter. Moreover, this Summary is not intended for use as an aid in determining the scope of the claimed subject matter.

In some aspects of the technology, a metal nipper assembly is provided. The metal nipper assembly comprises a metal nipper and a base plate. The metal nipper is formed from a metal that is corrosion resistant, such as, for example, stainless steel. The metal nipper has a pair of opposed arms that are joined at a spring hinge. The handles terminate on a distal end with opposed blades or cutting edges. The opposed arms converge from the distal end to a proximal end and act as levers. Pinching the opposed arms compresses the spring hinge and provides a pinching or cutting force to a blade. At least one of the two handles has a surface that is either magnetic or contains magnets. The base plate is either magnetic or contains magnets that align with and releasably, magnetically couple the metal nipper to the base plate. Of course, other means for a releasable connection are possible including other magnet to magnet connections. The metal nipper is releasably coupled to the base plate such that the metal nipper can be removed from the base plate by hand for use and stored on the base plate when not in use.

In some aspects of the technology, the base plate contains a sharpening portion, such as, for example, a groove. The sharpening portion is shaped such that a hook, such as a fish hook, a knife blade, or a nipper blade (either individually or together) can be sharpened on the base plate.

In some embodiments, the base plate is formed of a metal that is shaped to fittingly engage an article of clothing, such as, for example, a hat rim, a shoulder strap, or the like. In certain embodiments, the base plate is formed into the article of clothing.

In some aspects of the technology, a metal nipper assembly is provided. The metal nipper is formed from a metal that is corrosion resistant, such as, for example, stainless steel. The metal nipper has a pair of opposed arms, which may be referred to as elongate members, that are joined at a hinge. The arms contain at least one magnetic, such that magnetics of a polarity are opposed on the inside surface of the arm. The magnetics provide a force tending to open the arms (e.g., the magnetics repel each other), or nippers. The hinge allows rotation of the arms about an axle of the hinge and provides a stop to prevent over rotation of the arms. The arms terminate on a distal end with opposed blades or cutting edges. The opposed arms converge from the distal end to a proximal end and act as levers. Pinching the opposed arms compresses provides a pinching or cutting force to a blade. When the pinching force is removed, the magnetics force the opposed arms to open.

These and other aspects of the present system and method will be apparent after consideration of the Detailed Description and Figures herein.

DETAILED DESCRIPTION

The technology of the present application will now be described more fully below with reference to the accompanying figures, which form a part hereof and show, by way of illustration, specific exemplary embodiments. These embodiments are disclosed in sufficient detail to enable those skilled in the art to practice the technology of the present application. However, embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. The following detailed description is, therefore, not to be taken in a limiting sense.

The technology of the present application is described with specific reference to a metal nipper assembly. However, the technology described herein may be used with applications other than those specifically described herein. For example, the technology of the present application may be applicable to forceps, line retractors, eye tools, knot tying tool, knife, box cutter, other blades, scissors, tippet holder, carabiner, leader straightener, fly patch holder, floatant holder, or the like. Moreover, the technology of the present application will be described with relation to exemplary embodiments. The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. Additionally, unless specifically identified otherwise, all embodiments described herein should be considered exemplary.

With reference now to FIG. 1, a metal nipper assembly 100 is shown. The nipper assembly 100 is shown attached to an article 10, which in this exemplary embodiment the article 10 is an article of clothing and more particularly, the article of clothing is a hat 12 having a hat bill 14. The nipper assembly 100, however, may be attached to other articles 10 such as, for example, a shoulder strap, a belt, a belt buckle, a pocket, or the like. Also, while shown as attached to an article of clothing, the nipper assembly 100 may be clipped or snapped onto an article that is not clothing, such as a cooler strap or handle, a surface associated with a cooler, thermos, tackle box, or the like as well.

The nipper assembly 100 includes a metal nipper 105 and a base plate 115, which are shown coupled together in FIG. 1 and separate in FIG. 2. As shown in FIG. 2, the metal nipper 105 includes a first elongate member 102 and a second elongate member 104 each having a proximal end 106 and a distal end 108. The distal end 108 of each of the first and second elongate members 102, 104 terminates in a cutting edge 110, which may be a blade or the like. The first and second elongate members 102, 104 are coupled closer to the proximal end 106 by a spring hinge 112, as seen in FIG. 1. The spring hinge 112 in a particular embodiment is explained further below

During operation, the metal nipper 105 is removed from the base plate 115 as shown in FIG. 2. Pinching or squeezing the first and second elongate members 102 and 104 compresses the spring hinge 112 such that the cutting edges 110 move together to clip a fishing line, for example, or other object.

Metal nipper 105 is generally made from a metal that is corrosion resistant to general oxidation. One particularly good metal for corrosion resistant is stainless steel. While certain stainless steels are magnetic, conventional stainless steel is not magnetic. With reference to FIG. 3, an outer surface 300 of the second elongate member 104 is shown. The outer surface 300 of the second elongate member 104 generally abuts a top surface 302 (sometimes referred to as the mounting surface) of the base plate 115. The second elongate member 104 has at least one cavity 304 in the outer surface 300, although the exemplary metal nipper 105 has two cavities 304. Each of the cavities 304 includes a bore 306 in a base 308 (neither specifically shown) of the at least one cavity 304. The bore 306 may be a threaded bore. A magnetic element 310 is disposed in the cavity 304. The magnetic element 310 has a through bore 312 and a counterbore 314 that forms a shoulder. A fastener 316, such as a set screw, couples the magnetic element 310 to the base first elongate member 104. In this particular embodiment, the fastener 316 is a set screw with a threaded shaft that threads into the bore 306 in the base. A head of the set screw abuts the shoulder formed by the counterbore 314. Thus, in this particular embodiment, threading the fastener 316 into the threaded bore 306 couples the magnetic element to the second elongate member 104.

The second elongate member 104 has a threaded bore 320 that aligns with a threaded bore 400 on the first elongate member 102, see FIG. 4. The threaded bores allow coupling the spring hinge 112 to the first and second elongate members 102, 104.

With reference to FIG. 5, the base plate 115 of the metal nipper assembly 100 is shown. The base plate 115, in this case, is a magnetic, metal material, such as steel, iron, or the like. The base plate 115 is formed from a sheet of the metal material. The base plate 115 has a first portion 502 coupled to a second portion 504, not specifically seen in FIG. 5, at a spring bend 506. The spring bend 506 is formed by rolling/folding the second portion 504 back over the first portion 502 to form a clamp space 508. The clamp space 508 separates the first portion 502 and the second portion 504 by a first thickness T₁. The first thickness T₁ is sized to be smaller than the article to which the base plate 115 is attached. In other words, the clamp space 508 is slightly smaller than a second thickness T₂, where the second thickness T₂ is the thickness of the article to which the base plate 115 will be attached.

When attaching the base plate 115 to the article 10, the clamp space 508 is expanded to fit onto the article 10, such as the hat bill 14 shown, to which the base plate 115 is attached. The expansion of the clamp space 508 plastically deforms the spring bend 506 that provides a compression force to clamp the article 10 between the first portion 502 and the second portion 504. To facilitate sliding the base plate 115 onto the article, the edges of the base plate 115 may be chamfered or beveled.

The base plate 115, alternatively, may be incorporated directly into the article 10. For example, the base plate 115 may be attached directly to a bill member and stitched in place by the fabric stitching. The base plate 115 may be covered by fabric, or other material, in certain embodiments. If the base plate 115 is covered by fabric, or other material, the covering should be such that it does not interfere with the magnets. The base plate 115, in certain embodiments, may be permanently affixed to the article 10, such as, for example, by being directly incorporated, glued, welded, or the like to the article.

The base plate 115 includes a groove 510. The groove 510 may be sized to receive a fish hook, a knife blade, the nipper cutting edge, or the like. The groove 510 is designed to allow for sharpening of the fish hook, knife blade, nipper cutting edge, or the like. To facilitate the durability and sharpening, the base plate 115 may be diamond coated.

FIG. 6 shows an exploded view of the metal nipper 105 with the spring hinge 112 shown in more detail for this exemplary embodiment. The spring hinge 112 of this particular embodiment is shown and described here for completeness, but other means for hinging the first and second elongate members 102, 104 are possible. In this particular embodiment, the first and second elongate members have facing, opposed surfaces 502, 504. Each of the facing, opposed surfaces 502, 504 contains at least one socket 506 to receive a ball 508, such as a ball bearing. The present exemplary embodiment contains two sockets 506 in each of the facing opposed surfaces 502, 504 and a pair of balls 508. The threaded bores 320 and 400 are aligned to receive the fastener 316, such is a screw 316 in this embodiment. A coil spring 510 is contained between the first and second elongate members and generally under compression, which tends to cause the coil spring 510 to provide an expansion force moving the first and second elongate members 102, 104 aware from each other. The fastener 316 holds the first and second elongate members 102, 104 together on the balls 508 with the coil spring 510 in compression. Pinching the first and second elongate member 102, 104 causes the distal end 108 (and cutting edges 110) to move towards each other and cut. This action puts the coil spring 510 under compression such that when the pinch force is removed, the distal end 108 opens. The facing, opposed surfaces 502, 504 may have divots 512 to contain the coil spring 510. As can be appreciated from FIG. 6, each facing, opposed surface 502, 504 has a pair of divots 512 and two coil springs 510.

FIGS. 7 and 8 show another embodiment of a nipper assembly 600. The nipper assembly 600 is similar to the nipper assembly 100, which similarities will not be re-explained herein. The nipper assembly 600, however, has a different hinge construction than the nipper assembly 100 described in FIG. 6 above. The nipper assembly 600 comprises a first elongate member 602 (or first arm 602) and a second elongate member 604 (or second arm 604). The first elongate member 602 has a first surface 606. The second elongate member 604 has a second surface 608 opposed to the first surface 606. Both the first and second elongate member 602, 604 have proximal ends 610 and distal ends 612.

The second elongate member 604 has a pair of first tangs 614 at the proximal end 610, which is opposite the cutting edges not specifically labeled or described here. The first tangs 614 have aligned bores 616, which could be through bores as shown or blind bores. The first tangs have a sliding surface 618 shaped to engage a corresponding movement surface on the first elongate member 602, explained further below. The sliding surface 618 ends in a stop 620. The second surface 608 has at least one (1) cavity 622 that receives a magnet 624 (which could be the same magnet as described above that is used to couple the nipper assembly 600 to a base plate 115 or different magnets).

The first elongate member 602 has a pair of engagement lobes 626 at the proximal end 610. The engagement lobes are sized and shaped to rotate with respect to the first tangs 614. The engagement lobes 626 have aligned bores 628 that further align with the bores 616 of the first elongate member 602. A pin 630 extends through the aligned bores 616 and 626 such that the first elongate member 602 and the second elongate member 604 are hingedly coupled by the pair of first tangs and the pair of engagement lobes. In other words, the tangs 614, lobes 626, and pin 630 together form a hinge with an axle to allow rotation of the first elongate member 602 and the second elongate member 604. Although not shown, the second elongate member 604 has at least one cavity (1) 632, aligned with the at least one cavity 622, that has a magnet 634 (also not shown) having the same polarity as the magnet 624 such that the magnets 624 and 634 tend to repel. The first elongate member 602 has a movement surface 636 that is shaped to cooperatively engage the sliding surface 618. The movement surface 636 slides (relatively) over the sliding surface 618 until the second elongate member engages the stop 620. Thus, the magnets 624 and 634 provide a force tending to move the first elongate member 602 and the second elongate member 604 apart until the second elongate member engages the stop 620, e.g., the first elongate member 602 pivots about the pin 630 relatively to the second elongate member 604. During use, a user would pinch the first and second elongate members 602, 604 to overcome the magnet force to cause the cutting edge to engage.
