The present invention relates to archery bows and more particularly pertains to a slide arrangement for use with a bow and arrow.
In bowfishing, a fishing line is attached to the arrow that is projected at a target, allowing the arrow and any connected targets to be retrieved after firing. In certain arrangements, the line is attached to the arrow by an arrow slide arrangement that helps prevent the line from interfering with or becoming tangled with parts of the bow while the arrow is being drawn and released.
Bowfishing arrangements according to certain embodiments described herein include bowfishing slide apparatuses configured for use with archery bows. In typically embodiments, an archery bow includes a bow body with a riser and upper and lower limbs. A bowstring extends between the upper and lower limbs. An arrow is equipped with a stop near the rear of the arrow shaft and a slide assembly. The slide assembly includes a sliding portion configured to slide along an arrow shaft and a flexible strand to which fishing line is configured to be attached. In the illustrated embodiments, the flexible strand is engaged with and extends from the sliding portion. The stop may be arrangeable on the arrow shaft in a manner to prevent the slide member from sliding off of the arrow shaft.
In certain specific embodiments, the sliding portion defines two or more attachment points and an interior passage. The passage allows the sliding portion to translate along portions of the arrow shaft. The flexible strand has two or more attaching segments, each engaging an attachment point of the sliding portion, and defines a loop. The loop is sized to extend behind the arrow when the sliding portion is adjacent to the stop. In such embodiments, a fishing line is secured to the loop. The fishing line may be secured to the bow, for example to a reel secured to the bow body.
Other objects and attendant advantages will be readily appreciated as the same become better understood by references to the following detailed description when considered in connection with the accompanying drawings.
For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiments illustrated and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended, such alterations, modifications, and further applications of the principles being contemplated as would normally occur to one skilled in the art to which the invention relates.
Embodiments disclosed herein include a bowfishing arrow slide arrangement for use with an archery bow. In certain configurations, a slide is arranged on an arrow shaft and a flexible member is connected to both the slide and a fishing line. When a bow and arrow are in a drawn position, the slide is located at or near the front of the arrow. As the arrow is fired, the arrow slides through the slide until the slide contacts a stop located near the rear of the arrow, after which the flexible member trails the arrow and pulls the fishing line in a direction substantially along the path of the arrow.
The portion of the cable which defines the bowstring cable 34 includes an upper portion 28 and a lower end portion 30 which are fed out from cams 16 and 18 when the bow is drawn. The non-bowstring portions of the cable arrangement including return or cross cables extending between the cams and/or limb tips are not illustrated for ease of reference. Each cable has a thickness and one or more strands forming a round cross-section defining a circumference.
From the perspective of the archer, the bowstring is considered rearward relative to the riser which defines forward. Directional references herein are for ease of explanation and are not intended to be limiting. Similarly, a bow riser held with the left hand is illustrated, but is not intended to be limiting. A symmetric arrangement can be used with a bow having a right-handed riser.
When the bowstring 34 is drawn, it causes cams 16 and 18 at each end of the bow to rotate, feeding out cable and bending limb portions 12 and 14 inward, causing energy to be stored therein. When the bowstring 34 is released with an arrow engaged to the bowstring, the limb portions 12 and 14 return to their rest position, causing cams 16 and 18 to rotate in the opposite direction, to take up the bowstring 34 and launch the arrow with an amount of energy proportional to the energy initially stored in the limbs. Bow 10 is described for illustration and context and is not intended to be limiting.
Certain embodiments can also be used with single or hybrid cam compound bows. A single cam bow includes a similar riser with a handle, upper limb portions, and lower limb portions. Rotational members such as an upper idler wheel and a lower eccentric cam are supported at the limb tip sections for rotary movement about their axles. A bowstring cable includes an upper end fed-out from the upper wheel and a lower end mounted to an fed-out from the lower cam when the bow is drawn. A return cable portion has an upper end wrapped around the upper cam and a lower end mounted to the lower cam, with the lower end fed-out from the cam as the bow is drawn. Additionally, a y-yoke anchor cable has a lower end mounted to the lower cam and two upper ends mounted to the axle of the upper cam. The lower end is taken in to the lower cam as the bow is drawn. References herein to a bowstring or cable portion extending to the limb tips are intended to broadly include a cable portion wrapped around or mounted to a track of a rotational element or an attachment to an axle mounted at the limb tips.
The present disclosure can also be used in other types of bows, for example recurve bows, hybrid cam bows, or crossbows, all of which are considered conventional for purposes of the present disclosure. For convenience, the combination of riser 11 and either single or quad limbs forming upper limb 12 and lower limb 14 may generally be referred to as a bow body. It should be appreciated that a bow body can take on various designs in accordance with the many different types of bows. Similarly, a bowfishing arrangement can take on a variety of designs by adding a line or reel to any of the various bow body types.
In some variations, an arrow is included in the bowfishing arrangement and includes a shaft 40, a nock 42, and a point 44. The point is at the forward end of the shaft and the nock is at the rear and is adapted to engage with a bowstring. The arrow also includes a slide 50 and stop 60. The stop 60 is located along the rearward portion of shaft 40 near or part of nock 42. The slide 50 includes a slide body or a sliding portion 51 with an interior surface defining an interior passage 52 allowing the sliding portion 51 to slide along the arrow shaft 40. In certain embodiments, the interior passage 52 is generally cylindrical with an inner diameter that is approximately equal to the outer diameter of the shaft 40. The interior passage may be shaped differently in other embodiments. Stop 60 prevents slide from sliding off the rear of the shaft 40.
The slide 50 further includes a flexible strand or flexible member 70 engaged with and extending from the sliding portion 51. In the particular illustrated embodiments, the sliding portion 51 may have two or more attachment points 56, 58 where the flexible member 70 engages with the sliding portion 51 (see
Preferably, the loop 76 may be long enough to extend behind the rear of the arrow when the slide 50 is arranged on an arrow shaft and the slide 50 abuts the stop 60. For example, the loop 76 may define a length or a distance which it extends from the sliding portion 51 along a straight line axis. The distance the loop extends from the sliding portion 51 may be more than twice the distance from the rear of the sliding portion 51 to the rearward end of the arrow shaft when the sliding portion 51 abuts the stop 60. In optional embodiments, including the illustrated embodiment, a portion of the flexible member 70 may be gathered or pulled together by clasp 77 to form a secondary loop 78. The secondary loop 78 can be sized and arranged so that an attached fishing line 36 can be secured at or near the central point 79 of the secondary loop 78. If the secondary loop 78 is absent, the fishing line 36 may be secured to the loop 76. The flexible member 70 may be formed from a variety of materials, including but not limited to wire, string, or synthetic filaments. The member 70 may be a single strand of material or multiple strands. When multiple strands are used, the strands may optionally be twisted or braided to increase strength of the member and avoid tangling of strands.
In arrangements where loop 76 is sized to extend behind the rear of the arrow shaft 40 when the sliding portion 51 is adjacent to the stop 60 such as, for example in
In certain arrangements, some or all of the exterior of the sliding portion 51 approximates the shape of a truncated cone, truncated pyramid, or other form of frustum. The truncated form may have a variety of different base shapes. As examples, the form may be circular, elliptic, or polygonal in cross-section. In one specific example, all or a substantial portion of the sliding portion 51 may be frusto-conical in shape. In
The sliding portion 51 may, in some variations, be rotatable around the arrow shaft 40. For example, the sliding portion 51 may have a substantially cylindrical interior passage 52 that allows the sliding portion 51 to rotate around an arrow shaft with a circular cross-section. In other forms, as shown in
Preferably there is minimal translational friction between the sliding portion 51 and the arrow shaft 40. In some forms, at least the portions of the sliding portion 51 in contact with an arrow shaft may be formed from self-lubricating materials, such as Delrin® plastic to give one non-limiting example. Alternatively, the interior passage of the sliding portion 51 may be lubricated or it may be coated with low friction materials, such as Teflon® coating, to reduce friction. In some forms, the arrangement of alternating recessed portions 55 and raised portions 57, as seen in
According to other alternative variations, as shown with reference to
Preferably, attachment points 56, 58 may be located on diametrically-opposed sides of the sliding portion 51. In certain embodiments, the sliding portion 51 may be formed so that attachment points 56, 58 are on the rearward end of the sliding portion 51 closest to the nock, as in
In other embodiments, as depicted in
In use, a bowfishing archery bow may be used to shoot an arrow. With a bow, an arrow, a stop near the rear of the arrow, a sliding portion on the shaft of the arrow, and a flexible member attached to the sliding portion and secured to one end of a fishing line with the other end secured to the bow body, the nock of the arrow is placed adjacent to the bowstring in an undrawn position. As the bowstring and arrow are pulled rearward, drag on the slide allows the shaft to pass through the sliding portion and the sliding portion, the flexible member, and the fishing line may remain substantially in front of the riser or aligned adjacent with the riser body. Once the bow is drawn, the bent limbs of the bow body store energy. When the bowstring is released, the limbs return to their original position and kinetic energy is transferred to the arrow. As the arrow is projected forward, it moves faster than and through the sliding portion, relatively translating the slide towards the rear of the arrow. When the sliding portion reaches the stop, a portion of the flexible member is pulled to a position trailing the arrow, and the fishing line is pulled by the arrow substantially along the trajectory of the arrow. Optionally yet preferably, the fishing line can be used to retrieve the arrow and any items attached thereto.
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiments have been shown and described and that all changes and modifications that come with the spirit of the invention are desired to be protected.
