The present invention relates generally to a sling apparatus, and more specifically, to a sling apparatus adapted for carrying various objects, devices and equipment, such as without limitation, archery bows, ski and snowboard equipment and firearms.
Bow slings that can be removably fastened to a bow are well known in the prior art. For example, U.S. Pat. No. 4,760,944, issued on Aug. 2, 1988, to Hughes, discloses a sling that includes a pair of mounting members formed of wrap around fabric and hook and loop type fasteners. The mounting members are secured to the bow at each of two junctures which are located thereon between one of its limbs and its riser or handle. With the hook and loop fasteners, the mounting members can be secured to the bow without modifying it. Prior to the bow's being used, however, the sling must be removed, or it may interfere with the operation of the bow.
U.S. Pat. No. 4,768,689, issued on Sep. 6, 1988, to Davis, discloses a sling that includes a strap with hook attached to each end. The hooks are configured to hold the string of a bow. The bow is thus held to the hooks by its weight and can be removed from the sling by lifting the bow to disengage the hooks. The sling can be inadvertently or unintentionally removed from the one or both of the hooks as it is only held to the hooks by the weight of the bow.
U.S. Pat. No. 5,038,987, issued on Aug. 13, 1991 to Huddleson, discloses a sling connected to a bow string holder. The sling is held in the bow string holder by the weight of the bow and lifting of the bow allows the bow string to be removed from the holder. Like Davis above, the holder can be inadvertently or unintentionally removed from the bow string as it is only held to the adapter by the weight of the bow.
U.S. Pat. No. 5,239,976, issued on Aug. 31, 1993, to Specht, discloses a sling connected to an adapter attached to a bow. A cable or strap of the sling is held in the adapter by the weight of the bow and lifting of the bow allows the cable or strap to be removed from the adapter. Like Davis and Huddleson above, the sling can be inadvertently or unintentionally removed from the adapter as it is only held to the adapter by the weight of the bow.
U.S. Pat. No. 5,730,341, issued on Mar. 24, 1998, to Hester, Jr. discloses a sling attached to a bow using two brackets mounted on the bow by weight adjustment screws of the bow. Once attached, the sling is not configured to be readily removable from the bow during use.
U.S. Pat. No. 8,622,265, issued on Jan. 7, 2014, to Arajakis, discloses a sling strap having key hole clips at each end of the strap. Attachment straps are configured to engage with the keyhole clips to hold the sling strap to the attachment straps, which have been secured to the risers of a bow. Each end of the sling strap can be removed from the head of the attachment strap to which it is attached by sliding the head within the keyhole until it can be removed.
U.S. Pat. No. 9,146,073, issued on Sep. 29, 2015, to Roy, discloses a sling for suspending an archery bow from an archer's shoulder that has a pair of retracting mechanisms attached to a shoulder pad with cords. When the sling is removed from the archer's shoulder, the retracking mechanisms draw the cords causing the sling to draw tight between the retracting mechanisms. The sling, however, is not configured to be readily removable from the archery bow during use.
U.S. Pub. No. 2012/0043362, filed on Aug. 23, 2010, by Smith, discloses a harness worn about a hunter's chest. A bow string holder is carried by the harness and attaches to the string of the bow to allow the bow to hang from the bow string holder and thus from the harness. Tension created by the hanging of the bow from the bow string holder prevents the bow string holder from releasing the string until the tension is released upon the hunter lifting the bow from the sling for shooting. Like Specht, Davis and Huddleson above, the sling can be inadvertently or unintentionally removed from the bow as it is only held to the bow by the weight of the bow.
Thus, there is a need in the art to provide a sling that is firmly attached to a device, such as a bow, when desired, such as when carrying the device, but that can be quickly and easily released so that the sling does not interfere with operation of the device.
The present invention as shown and described herein provides such a sling and is a significant improvement over slings and the like known in the art.
Accordingly, a sling apparatus according to the present invention comprises a sling body having first and second arms downwardly extending therefrom, a first upper strap coupled to an upper portion of the sling body for carrying the sling body, a first release mechanism coupled to the first arm and a second release mechanism coupled to the second arm. The first and second release mechanisms are configured to attach to an object to be carried about a shoulder of a user. A trigger assembly is attached to the sling body and coupled to the first and second release mechanisms, whereby pulling a trigger of the trigger assembly will allow detachment of the first and second release mechanisms from the object.
In one embodiment, the sling apparatus is configured to carry a bow.
In another embodiment, the sling body is generally elongated and has a rectangular or trapezoidal shape.
In another embodiment, the first strap is part of a shoulder strap attached to and between top lateral sides of the sling body so that the sling body can be supported by the shoulder of the user.
In yet another embodiment, the trigger assembly is housed at least partially within the sling body.
In still another embodiment, the trigger assembly is positioned toward a front of the sling body so that the trigger is easily accessible by a hand of the user.
In yet another embodiment, the trigger assembly is linked through each of the first and second arms to the first and second release so that when the trigger is pulled, the two release mechanisms simultaneously open and release the object to which first and second release mechanisms are attached.
In another embodiment, the trigger assembly comprises a housing that defines a trigger slot sized and shaped for receiving the trigger, but that is longer than the trigger thereby forming a space between a back end of the trigger and a back wall of the trigger slot, the space allowing the trigger to slide from front to back within the trigger slot.
In another embodiment, biasing members are positioned between the back of the trigger and a back of the trigger slot to bias the trigger toward a front end of the trigger slot.
In yet another embodiment, a cable having a first end is coupled to the first release mechanism and a second end coupled to the second release mechanism and coupled to the trigger assembly, whereby pulling the trigger pulls the cable relative to the first and second release mechanisms.
In another embodiment, the trigger comprises a trigger body having a generally rectangular outer shape and a central aperture, a front end of the trigger body defining a C shaped channel, the cable extending to and between proximal ends of cable sleeve ends positioned proximate respective ends of the C shaped channel
In still another embodiment, when the trigger is pulled, the cable is pulled in precisely equal lengths relative to each side so as to cause the first and second release mechanisms to release the object to which they are attached substantially simultaneously.
In yet another embodiment, the trigger of the trigger mechanism is biased to keep the release mechanisms in a closed position.
In still another embodiment, each of the first and second release mechanisms are comprised of a housing to which first and second clamping members are pivotally attached, a slidable clamp actuation member, a first biasing member biasing the clamping members into an open position, and a second biasing member for biasing the actuation member into engagement with the first and second clamping members. The actuation member being retractable from the first and second clamping members by the cable allows the first and second clamping members to open into the open position.
In another embodiment, each of the first and second clamping members have laterally extending first and second tabs wherein the second biasing member engages the first and second tabs to bias the first and second clamping members into an open position.
In yet another embodiment, the actuation member includes first and second forward extending tabs that when engaging with a respective one of the first and second clamping members pivots it into a closed position.
In still another embodiment, the first and second forward extending tabs are provided with beveled edges to provide a smooth transition surface between proximal ends of the clamping members to allow the clamping members to automatically move to a closed position.
In yet another embodiment, the first and second forward extending tabs are provided with blunt edges to provide an abrupt transition surface between proximal ends of the clamping members and the tabs to hold the clamp members in the open position.
In another embodiment, each of the release mechanism comprise a thumb actuation member for actuating the release mechanism.
In yet another embodiment, the first upper strap is configured to couple to a shoulder strap of a backpack.
In still another embodiment, a second upper strap is attached to the body of the upper portion of the sling body at a second end of the sling body opposite a first end where the first upper strap is attached and is configured to couple to a body of the backpack.
The foregoing embodiments provide a sling apparatus with significant advantages and novel improvements over the prior art. These advantages and improvements are further set forth in of the drawings and detailed description of the invention that follows.
Those of ordinary skill in the art will realize that the following description of the present invention is illustrative only and not in any way limiting. Other embodiments of the invention will readily suggest themselves to such skilled persons, including, without limitation, combinations of features of the illustrated embodiments.
A trigger assembly 20 is attached to and housed at least partially within the sling body 12. The trigger assembly 20 is positioned toward the front of the sling body 12 so that the trigger 22 is easily accessible by a hand of the user. As will be described in more detail herein, the trigger assembly is linked through each of the two clamp arms 14 and 16 and to the clamps 24 and 26 so that when the trigger 22 is pulled, the two clamps 24 and 26 simultaneously open and release the object to which they are attached (e.g., a bow as shown and described herein below or other devices where a two point, releasable shoulder sling may be advantageous such as for a rifle). The length of each clamp arm 14 and 16 is to position the object to which they are attached at a comfortable height for the user relative to the trigger when releasing the object so that the object can be grasped and supported with one hand as the trigger 22 is pulled with the other. The shoulder strap 18 includes a shoulder pad 34 for resting on top of the shoulder of the user and adjustable length straps with adjustment buckles to adjust the length of the shoulder strap 18 thereby adjusting the position of the sling body 12 and trigger 22 and the object coupled to the clamps 24 and 26 relative to the shoulder of the user, thereby allowing the user to adjust the positioning of the sling body 12 and attached object by adjusting the length of the sling strap 18.
As shown in
The trigger 22 is comprised of a trigger body 50 having a generally rectangular outer shape and a central aperture 52. The aperture 52 has an arc shaped front end extending from proximate one lateral side of the trigger 22 to the other. The back portion of the aperture 52 is also arch shaped but is provided with a plurality of grooves to provide a gripping surface 54 for the trigger. This gripping surface 54 can be gripped by one or two fingers of the user extending their fingers through the aperture 52 to pull the trigger 22 so as to compress the springs 42 and 44.
The front end of the trigger body 50 defines a C shaped channel 60 that extends to and between the proximal ends of the cable sleeve ends 62 and 64. The channel 60 is sized and shaped to receive the cable 66 extending from and between the cable sleeve ends 62 and 64. When the front plate (not shown) of the trigger assembly 20 is placed over the trigger 22, the cable 66 is prevented from dislodging from the channel 60 as the trigger 22 is moved from front to back and back to front. Moreover, the elongate C-shape of the channel 60 and relatively sharp angled corners into the cable sleeve ends 62 and 64 prevents the cable 66 from sliding within the channel 60 when the trigger 22 is actuated in either direction. As such, as the trigger 22 is pulled toward the back of the housing 36, the cable 66 is pulled from each of the cable sleeves 63 and 65 in precisely equal lengths from each side so as to cause the clamps 24 and 26 to open substantially simultaneously. By the term “substantially simultaneously,” the inventor is referring to actuation of the clamps that occurs at nearly the same time so that the object to which the sling of the present invention is attached is fully released from both clamps when the trigger is pulled. That is, so long as both clamps open within the time it takes to fully pull the trigger of the sling, the clamps are considered herein to have substantially simultaneously opened at the same time. Likewise, when the biasing force from the springs 42 and 44 bias the trigger 22 toward the front of the housing 36, the cable 66 is forced into the cable sleeves 63 and 65 in precisely equal lengths on each side so that each clamp 42 and 44 (although already in an open state from being previously opened) are ready to be closed and remained in a closed state once the clamps are placed in a closed position as further described herein.
As shown in
When the trigger is released as previously described, the actuation member 78 may remain in the position as shown in

Conversely, in
There may be some advantages to maintaining the clamps in an open position upon removal from an object. For example, when the clamps are already in an open state, reattaching them does not require one to open them first, thus making reattachment much quicker. Otherwise, placement of a coil spring between the proximal end of the actuation member and the housing would always force the actuation member toward the clamp and cause the clamp to always be in a closed position when the trigger of the sling is not in a pulled state.

When it is desirable to release the bow 400 from the sling 10, the user grasps the bow 400 with one hand and engages the trigger with a finger of the other hand. When the user then pulls or slides the trigger to one side of the aperture, both of the clamps 24 and 26 are substantially simultaneously opened, thereby releasing the bow 400 from the sling 10 to be held by the user.
When it is desirable to reattach the bow 400 to the sling 10, the user, grasping the bow 400 with one hand, reattaches each clamp 24 and 26 to a respective attachment ring as previously shown and described herein. Each of the clamp arms 14 and 16 are made to be laterally flexible to allow a user to easily attach the claps 24 and 26 to the bow 400 as shown.
