Indicator with internal attachment mechanism

Abstract

A strike indicator and strike indicator tooling assembly for use in fishing. The strike indicator comprises two hemispheres that may form a substantially spherical outer dimension around fishing line. The two hemispheres may fit frictionally together to prevent movement or slipping of the fishing line between the two hemispheres once assembled. The hemispheres may be disassembled to replace the fishing line, and reuse the strike indicator. The tooling assembly comprises a top insert, and a bottom insert. The top insert and bottom insert compress around a foam sheet to form the spherical outer form figures of the two hemispheres.

DETAILED DESCRIPTION OF THE DRAWINGS

(19) The present disclosure relates to a strike indicator assembly comprising two substantially spherical hemispheres with coupling components. The assembly comprises a top hemisphere and a bottom hemisphere. Either of both of the bottom hemisphere or the top hemisphere may have an internal gap to facilitate the engagement of a screw assembly to connect the top hemisphere to the bottom hemisphere. In other embodiments, the internal gap can be partially in the top hemisphere and partially in the bottom hemisphere. The screw assembly may comprise a female nut coupling component that may be reversibly engaged with the male screw coupling component. In embodiments, nothing (aside from a captured fishing line) extends beyond a substantially cylindrical outer form factor that would cause the indicator to be imbalanced or cumbersome.

(20) Throughout this disclosure, the term substantially is used to make clear that the hemispherical or spherical form factor of the devices described herein need not be exact. As described in more detail below, in one embodiment these devices can be formed by compressing polymer foam, or in another by cutting cork to shape. Each of these processes has a tolerance and expected deviation. As shown in some of the drawings, in the polymer compression embodiment there may be slight lips at the base of the hemispherical portion, however it should be understood that this does not detract from the overall, substantially hemispherical nature of those components. Likewise, a slight misalignment between male and female portions of the nut and screw that holds these hemispheres is to be expected, and normal machining tolerances after quality control would not result in a device that is understood to have anything but a substantially spherical form factor. Depending on the processes and materials used, these tolerances can vary from device to device, and substantially is used as a stand-in to acknowledge the variability of these physical processes and materials. As a general matter, as described above, devices should be understood to be substantially spherical if they create negligible non-uniform drag that would be undesirable to a fly-fisher, such as those caused by conventional devices that include asymmetric or protruding features.

(21) Referring now to FIGS. 1A and 1B, a representative embodiment of an assembled strike indicator (102A and 102B, respectively). FIGS. 1A and 1B illustrate example embodiments of a side view of the assembled strike indicator. These two drawings show two similar embodiments; the version in FIG. 1A includes a small flange 112 (see FIG. 2A) formed during a manufacturing process, while FIG. 1B has a substantially spherical form factor that that eliminates this flange structure. Despite this minor structural difference, each of these overcomes the deficiencies of conventional devices described above.

(22) The top and bottom hemispheres (104A/104B and 106A/106B, respectively, as shown in FIGS. 2A and 2B) are interlocked using the screw assembly 200 (see FIG. 7). According to the side view in FIGS. 1A and 1B, fishing line 114 (see FIG. 8) of any diameter may run vertically, passing through where the two hemispheres abut one another. The fishing line 114 diameter may fall within the range of 0.10-0.60 mm, in embodiments. The top and bottom hemispheres (104A/104B and 106A/106B) may be held together using the screw assembly 200. The top and bottom hemispheres (104A/104B and 106A/106B, respectively) abut one another to form the spherical outer dimension of the assembled strike indicator 102A/102B, when the flat portions of the hemispheres abut one another.

(23) Different embodiments within the scope of the invention can have different sizes. For example a small sized embodiment can be configured for use with line sizes of 0.10 to 0.60 mm, and the device itself when assembled as a diameter of 0.65 inches (16.5 mm). A medium-sized device can be used with larger lines, such as from about 0.21 mm to about 0.60 mm, and the device has an assembled diameter of 0.85 inches (21.6 mm). A large-sized device can be suitable for lines having a diameter of 0.40 mm to about 0.60 mm, and have an assembled diameter of 1.05 inches (26.7 mm). Larger devices may be more suitable for larger line sizes, to correspond to expected fishing conditions and avoid snapping thin lines in extreme scenarios.

(24) In addition to the advantages described above, devices described herein can have interchangeable top and bottom hemispheres. For a variety of reasons both practical and aesthetic, an angler may wish to have two differently colored halves to the device, for example. By mixing and matching these colors or patterns, specific combinations can be formed based on angler preference, or in tournaments to indicate a sponsor or team. It is therefore contemplated that kits including one or more hemispheres (whether only top hemispheres, only bottom hemispheres, or a combination of top and bottom hemispheres) could be provided that would facilitate this type of mixing and matching. These kits could be all of one type (bottom or top hemispheres) or they could be an assortment. Likewise, the kits could include different styles or colors from one another, or they could all be the same type.

(25) Referring now to FIGS. 2A and 2B, a perspective view of a top hemisphere of a strike indicator, and a bottom hemisphere of a strike indicator, are shown. In this view, the screw 202 is still fully engaged with the nut 210 (FIG. 3), but the remaining foam of the top hemisphere 104 (which would normally be affixed to the screw 202) is pulled back for ease of viewing. The top hemisphere 104 and the bottom hemisphere 106 may define a gap 108 (FIG. 3) therebetween to facilitate engagement of the screw assembly 200 and eliminate the catching problem of conventional solutions. The screw 202 and the nut 210 are each coupled to their respective hemispheres (104 and 106), in the finished device. That coupling can be permanent (e.g., with adhesive or molding) in embodiments, or it can be semi-permanent or removable. In order to maintain a substantially spherical form factor for the overall assembled strike indicator 102 no matter how tightly or loosely screwed together the halves are, the screw 202 and the nut 210 are affixed to their respective hemispheres (104 and 106) at a central region thereof. As described above, the placement in the center may not be exact, but should be within standard part, assembly, and machining tolerances, such as by using molds described below at FIG. 9 et seq.

(26) Both the top hemisphere 104 and the bottom hemisphere 106 may be substantially the same size to facilitate a closer friction-fit when assembled. Each hemisphere has a flange 112 that extends around the flat perimeter of the hemisphere. Again referring the FIGS. 2A and 2B, the bottom hemisphere 106 illustrates the engagement of the screw assembly 200, and the female nut coupling component when screwed into the gap 108 of the bottom hemisphere 106. The surfaces of the top and bottom hemispheres (104 and 106), may be substantially flat to encompass a slight concavity.

(27) Referring now to FIG. 3, a representative embodiment of a strike indicator assembly 100 is shown. The strike indicator assembly 100 of FIGS. 1 and 2 includes a top hemisphere 104, a bottom hemisphere 106, a gap 108 within the bottom hemisphere 106, and a screw assembly 200 (see FIG. 8). The top hemisphere 104 and the bottom hemisphere 106 are identical in appearance and shape, aside from the gap 108 within the bottom hemisphere 106 to facilitate the setback of the screw assembly 200. In other embodiments, the gap can be present on one or both hemispheres. The top hemisphere 104, and the bottom hemisphere 106 may be made of a foam material, or any other reasonably compressible and buoyant material.

(28) Referring now to FIGS. 4 and 5, a representative embodiment of a top and a bottom hemisphere of a strike indicator (104 and 106), respectively, though again with the screw 202 still engaged with the nut 210. The top hemisphere 104 and the bottom hemisphere 106 may have a spherical outer dimension or form factor. While there may be some deviation from a perfectly spherical outer form factor due to manufacturing tolerances and compression or movement of the material that makes up the hemispheres 104 and 106, again it should be understood that by substantially spherical it is meant that there are no discontinuities or protuberances that significantly affect the overall article's performance as a spherical strike indicator. The top hemisphere 104, and the bottom hemisphere 106, may be made of a compressible foam. The bottom hemisphere 106 differs slightly from the top hemisphere 104, in the sense there may be a gap 108 within the bottom hemisphere 108 (see the cross-sectional view of FIG. 8 for more detail). The gap 108 within the bottom hemisphere allows for engagement with the screw assembly 200. The top and bottom hemisphere (104 and 106) interlock to form an assembled strike indicator 102.

(29) In another embodiment of FIGS. 4 and 5, the top hemisphere 104, and the bottom hemisphere 106, may be shaped in an ovular nature rather than spherical. The gap 108 within the bottom hemisphere 106 may be shaped to engage with a different sized screw or attachment mechanism. As shown in these figures, a flange 112 may also extend around each hemisphere (104, 106) at the edge of the faces where they intersect, though this does not detract from the overall spherical or oval form factor.

(30) Referring now to FIGS. 6 and 7, representative embodiments of a screw assembly 200 and its components. The screw assembly 200 comprises a male screw coupling component 202, with a head 204, and a threaded portion 206. The screw 202 may have a notch 208 to allow for a fishing line 114 to pass therethrough when the screw is engaged to the coupling component (e.g., 210). The screw assembly 200 also may have a female nut coupling component 210, with a centrally located aperture that allows for the threaded portion 206 of the screw 202 to threadingly engage with the female nut coupling component 210.

(31) As shown in FIG. 7, the nut 210 receives the screw 202, which has a lead 202A that is angled. This angled portion assists with getting the threading started, alleviating some of the complaints with conventional devices that are hard to manipulate in cold weather or with larger fingers or gloves.

(32) Referring now to FIG. 8A, an embodiment of a disassembled strike indicator with fishing line threaded therethrough. The top hemisphere 104 and the bottom hemisphere 106 are separated to illustrate the substantially flat hemispheres. The compression fit of the top hemisphere 104 and the bottom hemisphere 106 may aid in keeping the screw assembly 200 engaged tightly, while the screw assembly 200 holds the fishing line 114 in place and prevents slip or movement by fitting tightly on the line.

(33) Referring now to FIG. 8B, an embodiment of an assembled strike indicator with fishing line threaded through. The top and bottom hemispheres (104 and 106), may have substantially flat inner surfaces that interact when the screw assembly 200 is tightened. The compressibility of the foam locks around the screw assembly 200 to prevent movement and allow the hardware to create a friction fit. The screw assembly 200 locks around the fishing line 114 to hold it in place and prevent any slip.

(34) Referring now to FIG. 8C, an embodiment of an assembled strike indicator. The assembled strike indicator may be hollow in some embodiments for purposes of flotation. Rather than being a solid foam hemisphere, the strike indicator may have a foam, or other sufficiently buoyant material that defines the outer perimeter of the hemisphere, which the remainder of the hemisphere is hollow. The hollow nature of the strike indicator aids in flotation and can be lighter than a strike indicator that is solid.

(35) Referring now to FIGS. 9-13, embodiments of a strike indicator cutting die and tooling mold assembly. The tooling mold assembly 300 may consist of two aluminum or steel inserts. One of the inserts may be a top insert 302 with concave cavities that may form the spherical outer dimension of the top of the strike indicator 102. The other insert may be a bottom insert 306 which may also have concave cavities to form the other half of the spherical outer dimension of the bottom of the strike indicator 102. The top insert 302 and bottom insert 306 may be compressed to form the strike indicator 102 out of a foam sheet 308 or another suitable material.

(36) Referring now to FIG. 13, an embodiment of a compression molding tooling. The mold may comprise two aluminum or steel inserts, a top insert 302, and a bottom insert, 306. The top insert 302 and the bottom insert 306 may each have air vents 304 to increase ventilation during the compression process. The top insert 302 and the bottom insert 306 come together to compress a foam sheet 308, forming the spherical outer dimensions of the top hemisphere 104 and the bottom hemisphere 106 of the strike indicator 102.

(37) Referring now to FIG. 14, an embodiment of a molded sheet of foam prior to cutting is shown. The foam sheet 308 may be cut to any diameter suitable for the strike indicator 102. After compressing and cutting the foam sheet, the female nut coupling component 210, and the male coupling screw component 202 may be arranged in the hemispheres cut from the foam sheet 308.

(38) Referring back to FIG. 3, in assembly, the strike indicator assembly 100 may have three components: the top hemisphere 104, the bottom hemisphere 106, and the screw assembly 200. The screw assembly 200 may be comprised of the female nut coupling component 210 having a centrally located aperture, and the male screw coupling component 202, having the head 204 and the threaded portion 206. The screw assembly 200 may be assembled by engaging the female nut coupling component 210 with the threaded portion 206 of the male screw coupling component 202.

(39) The gap 108 within the bottom hemisphere 106 accepts the nut 210, which in turn accepts the screw coupling component 202, such that screw assembly 200 holds the hemispheres 104 and 106 together. The gap 108 within the bottom hemisphere 106 may be present in the top hemisphere 106 in an alternate embodiment. The top hemisphere 104 and the bottom hemisphere 106 may be connected by engaging the flat portion of the top hemisphere 104 with the head 204 of the male screw coupling component 202, such as by adhesive. The foam of the assembled strike indicator 102 may be reasonably compressible and allows for a friction fit locking mechanism to hold the top hemisphere 104 and the bottom hemisphere 106 together.

(40) Each hemisphere may have a slight indentation on the inner surface so that once they are screwed together (using the screw assembly 200), the flange 112 of each hemisphere will still fit tightly together. The indentation on the inner surface of each hemisphere may assist with the friction-fit primarily caused by the locking nut and screw, because the internal assembly components may be further compressed to prevent movement of the fishing line 114. Without said indentation the foam may become too dense to allow the screw and nut hardware to come together and lock the line. The male screw coupling component 202 may be relatively large to support a friction-fit of the top and bottom hemisphere. The male screw coupling component 202 may thereby force the foam of each hemisphere to compress around the head 204 of the male screw coupling component 202.

(41) In operation, the top hemisphere 104 and the bottom hemisphere 106 allow for fishing line 114 to be attached internally, passing through the space between the top hemisphere 104 and the bottom hemisphere 106. The fishing line 114 may pass through the notch 208 to be secured in the center of the assembled strike indicator 102. The notch 208 facilitates use of any diameter of fishing line 114 up to the width thereof, preventing the need to have different sized screws and attachment mechanisms. The notch 208 also ensures that the line passes substantially through the center of the strike indicator assembly 100, preventing imbalance. The internal attachment of fishing line 114 enables easy application and repositioning of the assembled strike indicator 102.

(42) The tooling mold assembly 300 may be a two-step process. FIGS. 9-12 are the dies used to cut molded foam hemispheres out of the sheet. FIG. 10 shows cutting die 350 and compression mold tooling 352. FIG. 11 shows these same components from a rear perspective view, while FIG. 12 is a read view. FIG. 13 is a detailed view of the inside of the compression molding tooling, which is a part of the tooling mold assembly 300. That is, if the halves 352A and 352B or the compression mold tooling 352 were separated, the interior view is what is shown in FIG. 13. The cutting die 350 of FIG. 13 includes cutting edges 354. An aluminum or steel fixture may be used to ensure that the hardware gets placed at the right depth in relation to the foam. This may be necessarily if foam tolerances are too great to ensure hardware placement at a consistent depth. It should be understood that while a cutting die (350) or compression mold tooling (352) may be used in some embodiments, other widely used mechanisms for cutting, machining out, or either subtractively or additively forming foam or hollow spheres or hemispheres can be used.

(43) The tooling mold assembly 300 may be a compression-based system. The top insert 302 and the bottom insert 306 engage around the foam sheet 308 to form the spherical outer form factor of each hemisphere. As the top insert 302 and bottom insert 306 are heated and pressed together around the foam sheet 308, the mold of each hemisphere is formed. Then the foam sheet 308 can be cut to remove the finished hemispheres. In another embodiment, the tooling mold assembly may have top inserts 302 and bottom inserts 306 that vary in size. In yet another embodiment, the foam sheet 308 may be any material that is light and buoyant to create the strike indicator 102.

(44) In another embodiment, a solid screw may be used rather than a split screw. A user can wrap the line around the solid screw, rather than passing the line through the split screw as described above. Advantages to this arrangement are less complex parts and ease of use for some users, for whom threading the screw could be difficult. Wrapping the line around the screw is a quick alternative to threading the line through a split screw and can be done even while the two hemispheres are partially threadably connected, but wrapping the line can also be harder on the line as it is being turned at a tight angle with force applied thereon, which can cause breakage.
