Device for mounting imaging equipment to a bow and method of recording a hunt

Description

BACKGROUND

Bow hunters often desire to record a hunt, especially that moment in time when the bow is raised in preparation for a shot, a shot is launched at the target and the target reacts to the shot.

Generally, a hunter does not have sufficient time or space to both aim and fire a camera and aim and fire a bow once a target is spotted, especially since targets tend to move frequently between the time the target is spotted and the time a shot is fired at the target.

A number of devices have been developed for mounting a camera to a bow whereby aiming the bow at a target inherently results in aiming the camera at the target. Exemplary mounting devices are described in U.S. Pat. Nos. 4,296,725, 4,643,159, 4,890,128, 5,611,324 and 6,556,245, and United States Patent Application Publication 2005/0246910.

While generally effective for allowing the recording of a hunt, such mounts are not configured and arranged to accommodate the mounting of standard cameras, do not properly dampen the recoil effect experienced upon release of an arrow from the bow—resulting in a temporary “blinding” of the camera at a critical point in the hunt, are expensive and/or difficult to use.

Accordingly, a need exists for an inexpensive device capable of allowing quick and easy vibrational dampened mounting of a standard camera onto a bow.

SUMMARY OF THE INVENTION

A first aspect of the invention is a device for operably mounting a camera to a bow. The device includes a guideway, a mounting bracket assembly, a biasing system, and an attachment mechanism for securing a camera to the device. The guideway extends in the longitudinal direction, with the proximal longitudinal end configured and arranged for attachment to a bow. The mounting bracket assembly includes at least a traveler, a strut and a shelf. The traveler operably engages the guideway for movement along the longitudinal length of the guideway. The strut extends transversely from the traveler. The shelf is attached to the distal end of the strut, whereby the shelf is transversely spaced from the traveler. The biasing system is operable for longitudinally biasing the mounting bracket assembly away from both longitudinal ends of the guideway, whereby the mounting bracket assembly is biased into a rest position intermediate the longitudinal ends of the guideway.

A second aspect of the invention is a method for recording images of a hunt using the first aspect of the invention. Briefly, the method includes the steps of (1) obtaining a bow defining a median plane, (2) obtaining a camera, (3) obtaining the mounting device described in the preceding paragraph, (4) attaching the mounting device to the bow via an internally threaded stablilizer bore in the front of the bow such that the mounting device extends longitudinally forward from the bow and is laterally divided by the median plane defined by the bow, (5) activating the camera to start recording images, and (6) firing an arrow from the bow towards a target while the camera is activated.

DETAILED DESCRIPTION OF THE INVENTION INCLUDING A BEST MODE

Nomenclature

Referring to FIGS. 1 and 2, a first aspect of the invention is a device 10 for operably mounting a camera C to a bow B. The mounting device 10 includes a guideway 20, a mounting bracket assembly 30, a biasing system 40, and an attachment mechanism (not collectively numbered) for securing a camera C to the device 10.

The guideway 20 extends along a longitudinal axis x from a proximal longitudinal end 20p to a distal longitudinal end 20d. The guideway 20 serves to guide longitudinal x reciprocation of the mounting bracket 30 while limiting movement of the mounting bracket 30 in the lateral y and transverse z directions.

One embodiment of a suitable guideway 20 is depicted in FIGS. 1-7. The specific guideway 20 depicted in FIGS. 1-7 includes a center rod 21 retained within a housing unit 22. The housing unit 22 is formed from a tube 23 with a first endcap 24 secured over the proximal longitudinal end 23p of the tube 23 and a second endcap 25 secured over the distal longitudinal end 23d of the tube 23 so as to enclose the ends of the bore 23₀₉ defined by the tube 23. A slit 23₀₈ extends along the longitudinal x length of the tube 23 with the lateral y width of the slit 23₀₈ sized to accommodating passage of the strut 32 on the mounting bracket assembly 30 through the slit 23₀₈, and the longitudinal x length of the slit 23₀₈ sized to accommodate longitudinal x reciprocation of the strut 32 along the longitudinal x length of the guideway 20.

As shown in FIGS. 5 and 6, each of the endcaps 24 and 25 has an inwardly projecting nub 24_Nub and 25_Nub, respectively. An interior longitudinal x bore 24a₀₉ and 25a₀₉ is provided in each nub 24_Nub and 25_Nub, respectively. The rod 21 is suspended along the longitudinal axis x of the channel 23₀₉ defined by the tube 23 by insertion of the proximal longitudinal end 21p of the rod 21 into the interior longitudinal x bore 24a₀₉ in the first endcap 24, and insertion of the distal longitudinal end 21d of the rod 21 into the interior longitudinal x bore 25a₀₉ in the second endcap 25.

The mounting bracket assembly 30 is (i) operably attached to the guideway 20 for biased longitudinal x reciprocation of the mounting bracket 30 along the guideway 20, and (ii) configured and arranged for securely supporting a camera C with the camera C oriented so that when the device 10 is attached to a Bow B the camera C views any targets at which the bow B is pointed.

One embodiment of a suitable mounting bracket assembly 30 is depicted in FIGS. 1, 2 and 8-10. The specific mounting bracket assembly 30 depicted in FIGS. 1, 2 and 8-10 includes a traveler 31, a strut 32 and a shelf 33.

The traveler 31 defines a longitudinal x bore 31₀₉. The guideway rod 21 extends through the bore 31₀₉ in the traveler 31 such that the traveler 31 can slide longitudinally x along the length of the rod 21.

The strut 32 extends transversely z from a proximal transverse end 32p attached to the traveler 31 through the longitudinal x slit 23₀₈ in the guideway tube 23.

The shelf 33 is attached to the distal transverse end 32d of the strut 32. The strut 32 preferably transversely z extends within a median plane xz defined by the shelf 33 so that the device 10 is laterally y symmetrical and balanced relative to the median plane xz defined by the device 10.

The traveler 31 is longitudinally x biased into a rest position intermediate the longitudinal ends 21p and 21d of the rod 21 by a biasing system 40. Substantially any of the well know biasing means may be employed in the present invention including specifically, but not exclusively, elastic bands, compression springs, expansion springs, leaf springs, pneumatic cylinders, etc. As shown in FIG. 2, the embodiment of the invention depicted in FIGS. 1-11 employs first and second compression springs 41 and 42 to achieve the necessary biasing. The first compression spring 41 is positioned within the longitudinal x bore 23₀₉ of the tube 23 and compressed between the first endcap 24 at the proximal longitudinal end 23p of the tube 23 and a first annual shoulder 31r on the traveler 31 near the proximal longitudinal x end 31p of the traveler 31 for biasing the traveler 31 along the rod 21 in a first longitudinal direction x₁ away from the proximal longitudinal end 23p of the tube 23 and towards the distal longitudinal end 23d of the tube 23. The second compression spring 42 is positioned within the longitudinal x bore 23₀₉ of the tube 23 and compressed between the second endcap 25 and a second annual shoulder 31s on the traveler 31 near the distal longitudinal x end 31d of the traveler 31 for biasing the traveler 31 along the rod 21 in a second longitudinal direction x₂ away from the distal longitudinal end 23d of the tube 23 and towards the proximal longitudinal end 23p of the tube 23. The traveler 31, and hence the entire mounting bracket assembly 30 is biased into an intermediate position between the longitudinal ends 21p and 21d of the rod 21 because the first compression spring 41 longitudinally x biases the traveler 31 against the bias of the second compression spring 42, and the second compression spring 42 longitudinally x biases the traveler 31 against the bias of the first compression spring 41.

The device 10 may be attached to a Bow B by any convenient attachment mechanism or system ranging from hook and loop tape (not shown) to a mechanical clamp (not shown). A preferred attachment mechanism, depicted in FIG. 2, is a double end threaded collar stud 70 capable of engaging the device 10 at one end (unnumbered) via an internally threaded longitudinal bore 24b₀₉ in the first endcap 24 and engaging the bow B at the other end (unnumbered) via an internally threaded bore B₀₉ customarily provided in the front of a Bow B and commonly known as a stabilizer bore.

A camera C, or other electronic component such as a laser range finder (not shown) or GPS system (not shown), may be secured atop the shelf 33 by any convenient attachment mechanism or system ranging from hook and loop tape (not shown) to a mechanical clamp (not shown). A preferred attachment mechanism, depicted in FIG. 2, is a simple thumb screw 60 capable of extending from underneath the shelf 33 through a transverse hole 33₀₉ in the shelf 33 and into threaded engagement with internally threaded bore C₀₉ customarily provided in the bottom (unnumbered) of cameras C and other electronic equipment for use in securing the camera C to tripods (not shown) and other similar supports.

Another suitable attachment mechanism, depicted in FIG. 2 in phantom and shown in detail in FIG. 11, is a laterally y elongated strap 50 configured and arranged for attachment to the mounting bracket assembly 30 and equipped with a releasable fastener 51 (e.g., hook and loop tape) for strapping a camera C down onto the first major surface (unnumbered) of the shelf 33.

Use

The device 10 can be used to record images of a hunt with minimal interference or impact upon the hunt. The device 10 is employed by simply, (1) attaching the device 10 to a bow B at an internally threaded stablilizer bore B₀₉ in the front of the bow B so that the device extends longitudinally x forward from the bow B and preferably is laterally y divided by the median plane xz defined by the bow B, (2) proceeding with efforts to locate a target (not shown), such as deer, elk or other wild game, (3) activating the camera C to start recording images as desired, with a strong preference for activation shortly after a target (not shown) has been spotted, and (4) firing an arrow (not shown) from the bow B towards the target (not shown) while the camera C is activated. No other changes, adjustments or other interaction with the camera C is required to obtain a high quality photographic or video recording of the hunt, including a recording of an target (not shown) prior to, during and immediately after firing of an arrow (not shown) from the bow B at the target (not shown).

Release of an arrow (not shown) from the bow B caused the bow B to experience a recoil effect. This recoil effect would normally effect a momentary “blinding” of the camera C at one of the most exciting moments of a hunt (i.e., the moment the target is struck by the arrow and reacts). The mounting device 10 eliminates or substantially minimizes this “blinding” effect by allowing the camera C to longitudinally x reciprocate against a bias in both longitudinal directions x₁ and x₂, thereby quickly and efficiently damping the recoil effect.
