The present invention relates to archery products, and more particularly to a vane wrap system on an archery arrow to stabilize the arrow in flight.
Archery arrows typically are outfitted with feathered or polymeric vanes to stabilize the arrows in flight. Vanes produce lift and lateral force on the arrow, which in turn stabilizes the arrow's flight pattern by moving the center of pressure rearward. In turn, this usually provides consistent arrow flight and can improve shot accuracy.
Some manufacturers utilize special features of vanes to improve arrow flight and stablization. For example, some arrow vanes are curved to include a spiral shape. A popular arrow vane used by many archers is the SPINWING arrow vane, available from Range-O-Matic Archery Company of Ray, Mich. Sets of this arrow vane, and many other similar types, are typically applied to arrows with multiple, narrow strips of tape. To apply the vanes, a user must apply a set of markings, typically with a marker, around the circumference of the arrow, corresponding to future locations of each vane. The user then tediously applies multiple individual strips of tape over the markings, being careful to align each strip with the marking. Then, the user aligns each individual vane with a respective individual strip of tape, pressing the vane onto the tape.
While this application works, it is very tedious. There can be issues if the original markings on the arrow are off, as that will cause the vanes to be applied improperly, misalign the vanes, and typically cause off balanced spin and flight. Further, the pieces of tape are to be applied perfectly aligned with the markings, again assuming they are straight. If the tape is off, then the applied vane likely will be too, or the vane will not contact enough tape to properly attach the vane to the arrow. The strips of tape also are tiny, and require special attention to detail and placement. Typically, the strips are longer than the vanes, so the tiny strips also need to be carefully cut after placement of the vanes, which can add an extra, time-consuming step. In addition, due to the individual nature of the strips and vanes, the vanes can be imprecisely taped, so they might not attach fully and can detach from the arrow, or can be misaligned to cause erratic flight or less than perfect stabilization of the arrow.
Accordingly, there remains room for improvement in the field of archery vane attachment to an arrow.
A vane wrap for a projectile is provided where the wrap includes a base configured to wrap entirely around a circumference of a projectile, such as an arrow, and adhere to the arrow. The base includes an outward facing surface having a set of adhesive strips which are placed in predetermined locations and equally spaced about the circumference when the base is applied to the arrow. Each adhesive strip can include an individual corresponding release liner removable from the strip to expose the respective adhesive for application of a vane thereto, and to the arrow in predetermined locations.
In one embodiment, the base can be provided in a flat, planar sheet form. The base can include a lower surface and an opposing upper surface, a longitudinal axis, and a width perpendicular to the longitudinal axis. The lower surface can include an adhesive layer that is coextensive with the entire lower surface. The upper surface can include two or more elongated, individual adhesive strips aligned with the longitudinal axis and disposed across the width at a predetermined spacing from one another.
In another embodiment, the base sheet can include a first end edge and a second end edge distal from one another, at opposite ends of a length of the base sheet. The base sheet can also include a first side edge and a second side edge opposite one another, across the longitudinal axis. The base releaser liner can be coextensive with the base sheet on the lower surface, extending entirely to the first end edge, the second end edge, the first side edge, and the second side edge. The release liner can cover a base adhesive layer on the lower surface that also is coextensive with the base sheet to the edges.
In still another embodiment, a first adhesive strip and a second adhesive strip can be disposed on the upper surface of the base sheet, opposite one another across the longitudinal axis of the base. Each strip can be inwardly disposed from the first and second side edges, as well as the first and second end edges.
In yet another embodiment, first strip can be spaced a predetermined first distance from the second strip at respective centerlines of the strips. The first distance can be one half, one third or one quarter the circumference of the arrow to which the base sheet is to attach.
In even another embodiment, the strips can be placed on the base such that the strips closest to the side edges lay unequal distances from the side edge to which they are closest. In this manner, the one side edge can form an overlap region such that when wrapped around the circumference of an arrow, the first and second side edges overlap.
In a further embodiment, the base can include a first adhesive strip and a second adhesive strip, each covered by respective first and second release liners. The adhesive strips and the release liners can each be of a second length that is shorter than a first length of the base sheet.
In still a further embodiment, a first upper end of a first adhesive strip and second upper end of a second adhesive strip can be each disposed a first end distance from the first end edge. A first lower end of a first adhesive strip and second lower end of a second adhesive strip can be each disposed a second end distance from the second end edge. The first end distance can be less than the second end distance so that the base sheet extends a greater length beyond the adhesive strips below them, closer to an arrow tip, than above them, closer to an arrow nock, on an arrow.
In yet a further embodiment, the base sheet can be outfitted with three or four or more adhesive strips and corresponding release liners. Thus, three vane, four vane or other vane configurations on arrows can be produced with the vane wrap.
In even a further embodiment, a method of installing vanes on an archery arrow is provided. The method can include providing the vane wrap; removing a base release liner from the base adhesive layer; adhering the base sheet around a circumference of an archery arrow with the base adhesive layer so that the vane wrap follows the contours of the archery arrow and wraps around the circumference; removing a first release liner from the first adhesive strip; applying a first vane to the first adhesive strip; removing a second release liner from the second adhesive strip; and applying a second vane to the second adhesive strip.
The vane wrap of the current embodiments is well-suited to precisely and efficiently apply individual vanes to an arrow. With the preplaced adhesive strips on the base sheet, a user can quickly apply vanes at those locations with little guesswork. The exact, low tolerance positioning of the adhesive strips across the width of the base sheet and thus the circumference of the arrow to which it is attached provides precise and consistent orientation and positioning of the vanes about the arrow. In turn, the applied vanes precisely and predictably provide consistent spin and stabilization of the arrow or projectile in flight. The base sheet also provides a versatile platform to two, three or four adhesive strips so that a corresponding number of vanes can be precisely applied to the base to a user's preference. The vane wrap also makes the application of vanes to the vane wrap less tedious and much less time consuming than conventional vane application systems.
These and other objects, advantages, and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiment and the drawings.

A vane wrap for use with a projectile in accordance with a current embodiment is illustrated in
As shown in
The base or base sheet shown in
With reference to
The vane wrap 10 also can include a base release liner 60 covering and/or concealing the base adhesive layer so that the base adhesive layer does not engage a surface unintentionally and bond or secure the vane wrap to that surface before installation on an arrow. The base release liner 60 can be disposed over the lower surface of the base sheet, separated at least partially from the base sheet via the adhesive layer sandwiched therebetween. The base release liner 60 can be in the form of a sheet as well. It can extend across the base width BW and along the base length BL, coextensive with the base sheet 20. The base release liner can have a base liner width equal to the base width BW and a base liner length equal to the base liner length BL. Of course, where the adhesive layer 50 is of a different shape or format from the base sheet, the release liner can extend primarily across that layer in a similar manner to cover the adhesive.
With reference to
The first adhesive strip 30 also can be separated from the side edges of the base sheet by different separation distances. For example, as shown in
Turning to
With reference to
As shown in
With reference to
The centerlines C1 and C2 of the respective adhesive strips also can be in a particular orientation relative to the longitudinal axis LA of the base sheet or vane wrap 10. For example, the first strip centerline can be on a first side of the longitudinal axis, while the second strip centerline can be on a second opposing side of the longitudinal axis. This can be the case regardless of how close the first strip is placed relative to the first side edge without extending beyond that edge 21.
The vane wrap 10 can include separate and independent release liners disposed over the respective adhesive strips 30 and 40. As shown in
Optionally, the first release liner 45 includes a first length and the second release liner includes a second length. The first length and second length can be equal to one another and less than the base length BL as shown. The release liners can be coextensive with each of the respective adhesive strips. The release liners can have lengths optionally less than three quarters, less than two thirds, or less than one half the length of the base BL. The release liners also can be spaced from the side edges and end edges similar to the adhesive strips which they cover. The first release liner also can include a first width and the second release liner can include a second width. The first width and the second width can be optionally less than ½, less than ⅓, less than ¼ or other portions of the base liner width or base width BW.
As shown, the release liners are separate and independent, with one capable of being removed from one adhesive strip without pulling the other release liner off the other strips. Optionally, the release liners can be connected, however, for example, a remnant strip (not shown) can extend across from one liner to the other over the upper surface of the base to connect two or more release liners. One liner can be removed from one strip, and then can dangle via an attachment to the other remaining installed liner. Further optionally, the first release liner and second release liner can be formed of a continuous unitary strip wide enough to cover both adhesive strips.
A method of installing the vane wrap 10 to an arrow will now be described. In general, the method can include the following steps: providing the vane wrap; removing a base release liner from the base adhesive layer; adhering the base sheet around a circumference of an archery arrow with the base adhesive layer so that the vane wrap follows the contours of the archery arrow and wraps around the circumference; removing a first release liner from the first adhesive strip; applying a first vane to the first adhesive strip; removing a second release liner from the second adhesive strip; and applying a second vane to the second adhesive strip. Where more adhesive strips and release liners are included on the vane wrap, the release liners can be removed and the additional vanes installed.
More particularly, a user can obtain a vane wrap 10 and lay it out in a planar form. The base release liner 60 can be removed from the base adhesive layer 50. The first and second release liners remain attached to the first and second strips 30 and 40. The base sheet 20 can be turned over, adhesive layer 60 facing up, optionally on a rolling pad. The user can take a clean archery arrow and place it adjacent the base sheet, aligning the upper or first end edge with the end of the cylindrical arrow shaft. The user can roll the arrow as straight as possible to adhere the base sheet around the circumference of the arrow as the arrow rolls over. During the rolling, the base sheet adheres to the contours of the arrow, changing from a planar configuration to a curved configuration, wrapping around the arrow's circumference. The base sheet 20 adheres to the arrow until the second end edge 22 overlaps the first end edge 21 to create the overlap region 220L where the base width BW is greater than the circumference C of the arrow. The overlap region can be pressed down to secure the vane in place.
With the vane wrap 10 installed on the arrow, the vane wrap has the configuration shown in
The vane V1 can be applied to the arrow with the vane secured at the nock end of the arrow first. The vane V1 can be place at or slightly inside the outer edge of the adhesive strip, depending on its width, which may or may not be greater than the width of the base of the vane V1. That end of the vane V1 can be held while the end farthest from the nock is also placed at or slightly inside the outer edge of the adhesive strip. The exposed vane edge can be rubbed and pushed into engagement with the entire length of the adhesive strip.
After the first vane V1 is attached to the first adhesive strip, shown in
When the vanes are installed on the arrow, they can be disposed at an angle A1 taken between the respective centerlines C1 and C2 of the adhesive strips as shown in
The vanes installed on the vane wrap 10 can be constructed from a rigid or semi rigid but flexible material. This material can be a polymeric material, such as MYLAR®, natural or synthetic rubber, silicone, a composite material or other material. In some applications, the material can be an alloy or metallic. Generally, the material can retain its general shape as an associated arrow is accelerated and flies during flight. The material, however, can withstand the impact of the vane with a bow riser or an arrow rest without permanent deformation so that the vane can be used multiple times and provide similar aerodynamic effects on the arrow to which the vane is attached. Again, these aerodynamic effects can include spinning, rotating or otherwise reorienting the projectile to which the vane is attached.
A first alternative embodiment of the vane is illustrated in
As shown in
With reference to
The method of installing the arrow wrap 110 of this embodiment is virtually identical to that of installing the arrow wrap 10 as described above, except that one more release liner 175 is removed to reveal another adhesive strip 170 to install a third vane V3, in addition to the other vanes V1 and V2 as shown in
