[0019] Referring to
[0020] The housing 102 includes a first side 116 (also referred to as a tree facing back side 116) adapted to contact/abut the tree 200 and a second side 118 disposed spaced apart and opposite to the first side 116. In an embodiment, the first side 116 is a concave side, and includes a concavity to facilitate a relatively increased contact surface area with the tree 200 to provide an increased frictional engagement between the housing 102 and tree 200. In an embodiment, the first side 116 may also include a plurality of projections 120 (shown in
[0021] The housing 102 further includes a first handle 134 integrally formed on the third side 130 of the housing 102 and defining a first though hole 136. The first handle 130 extends in a longitudinal direction of the housing 102 such that the first through hole 136 extends laterally to the third side 130. In this manner, the first through hole 136 extends along a width of third side 130. Similarly, the housing 102 further includes a second handle 138 integrally formed on the fourth side 132 of the housing 102 and defining a second though hole 140 between the fourth side 132 and the second handle 138. The second handle 138 extends in a longitudinal direction of the housing 102 such that the second through hole 140 extends laterally to the fourth side 132. In this manner, the second through hole 140 extends along a width of the fourth side 132. The first though hole 132 and the second through hole 140 facilitates an attachment of the holder 106 with the housing 102. A groove channel 148 may be formed along the outer surface 122 of the second side 118, generally forming a path for the holder between the first though hole 132 and the second through hole 140.
[0022] In an embodiment, the holder 106 may include a strap 150 and ratchet 152 for tightening the strap 150 around the tree 200. As shown, the strap 150 may pass through the first though hole 136 and the second though hole 140, and may wrap around the second side 118, the third side 130 and the fourth side 132. The strap 150 may include a first end portion 154 and a second end portion 156 adapted to wrap around the tree 200 to attach the housing 102 with the tree 200. To facilitate a secure attachment of the strap 150 to the tree 200, the first end portion 154 is attached to the second portion 156 by using the ratchet 152. In an embodiment, the ratchet 152 may be connected and disposed at the second end portion 156. For connecting the first end portion 154 to the second end portion 156 and tightening the strap 150, the first end portion 154 is inserted into the ratchet 152 and pulled through the ratchet 152, and the ratchet 152 is engaged until the strap 150 is sufficiently taunt. In an embodiment, the first end portion 154 and the second portion 156 may include a plurality of teeth 158, spikes, or other protrusions extending from an inner surface 160 of the strap 150 to increase a frictional engagement between the strap 150 and the tree 200. In an embodiment, rivets may be disposed on the strap 150 to allow a stainless-steel nail, or other rust proof/resistant nail or fastener to be driven through and firmly attach the strap 150 to the tree 200. Further, in an embodiment, the strap 150 may include one or more hooks 161 or rings attached thereto, to allow the hunter 300 to hang one or more items to the holder 106. In some embodiments, the strap 150 may be weather resistant and ultraviolet (UV) resistant.
[0023] Additionally, or optionally, the device 100 may include a retention assembly 162 (shown in
[0024] Additionally, or optionally, the device 100 includes a carabiner back up attachment 180 for attaching the housing 102 to the tree 200. The carabiner back up attachment 180 is attached to a top end 182 of the housing 102, and includes a first hook 184 attached to the top end 182 of the housing 102 and a second hook 186 connected to the first hook 184 and adapted to be coupled to the tree 200. In an embodiment, the carabiner back up attachment 180 may include a cord or a rope extending between the first hook 184 and the second hook 186 and attached to the first hook 184 and the second hook 186. To facilitate the attachment of the first hook 184 to the housing 102, the housing 102 may include a hook portion 188. The hook portion 188 may define a third though hole 190 for receiving the first hook 184 and facilitating the attachment of the first hook 184 with the housing 102. The second hook 186 is shown as a carabiner, but it may be other hooks or securing fasteners.
[0025] Referring to
[0026] As shown, the winch 506 is disposed within the space 520 and includes a shaft 522 extending from the first bracket 502 to the second bracket 504 and rotatable supported by the first bracket 502 and the second bracket 504. The winch 506 further includes a first disk 524 supported by the shaft 522 and attached to the first bracket 502, and a second disk 526 supported by the shaft 522 and disposed proximate to the second bracket 504. As shown, the first disk 524 is attached to the first bracket, 502 such that the first disk 524 remains stationary upon a rotation of the shaft 522. Further, the second disk 526 is connected to the shaft 522 such that the second disk 526 rotates along with the shaft 522 upon the rotation of the shaft 522.
[0027] Further, the spring 510 includes a first end portion 530 connected to the shaft 522 and a second end portion 532 connected to the first disk 524. As shown, the second end portion 532 of the spring 510 is connected to the first disk 524 at a location proximate to an outer periphery 534 of the first disk 524. In an embodiment, the second end portion 532 of the spring 510 may be connected to the second bracket 502. In such a case the first disk 524 may be adapted to rotate along with the shaft 522. The spring 510 is adapted to bias the shaft 522 to a first position (initial position), and is adapted to resist a rotation of the shaft 522 from the first position. In this manner, the spring 510 is adapted to bring or rotate the shaft 522 back to the first position. In an embodiment, the spring 510 may be a flat spiral spring. Alternatively, the spring 510 may be a torsional spring.
[0028] Referring to
[0029] The first lever 540 is pivotally attached to the second disk 526 such that the first lever 540 moves away from the first position, towards the second position, in response to the rotation of the second disk 526 (i.e. the shaft 522) reaching above a threshold speed. As a rotational speed of the shaft 522 exceeds the threshold speed, the first lever 540 reaches to second position due to the centrifugal force acting on the first lever 540, and contacts the teeth 548 of the ratchet wheel 540. In so doing, the locking assembly 512 applies the brake on the shaft 522 (i.e. the winch 506) and stops the rotation of the shaft 522 (i.e. the winch 506). In an embodiment, the first lever 540 is biased into the first position by a spring (not shown). In such a case, the first lever 540 returns to the first position from the second position upon a decrease of torque on the shaft 522 and locking assembly 512 below the spring bias of the spring 510.
[0030] Further, the device 100 includes a cable 550 having a first end attached to the retracting device 500 a second end 552 disposed outside or extending outwardly of the housing 102, and a latch 192 (best shown in
[0031] An operation of the device 100 is now explained. At first, the hunter 300 may attach the device 100 to the tree 200 using the holder 106. For so doing, in an embodiment, the hunter 300 may climb to the tree stand 400 and wrap the first end portion 154 of the strap 150 and the second end portion 156 of the strap 150 around a trunk of the tree 200, and tightens the strap 150 using the ratchet 152. In so doing, the first side 116 of the housing 102 abuts the tree 200 and frictionally engages with the tree 200. In some other implementations, the hunter 300 may attach or affix the device 100 to the tree 200 while being on the ground. In such a case, the hunter 300 may use a projectile gun to shoot a projectile that embeds into the tree 200. The projectile may include a wire that remains attached to the projectile gun. Thereafter, the hunter 300 may attach the device 100 to the wire and may be winched/spooled up onto the tree 200 via a tether. When the device 100 reaches the tree 200 and contacts the tree 200, a switch disposed on the first side 116 of the housing 102 may get depressed that may cause the spool to stop. Further, the depressing of the switch may activate the arms 164, 166 such that the arms 164, 166 grip the tree 200 and the spikes 168, 170 embed into the tree 200. In an embodiment, the device 100 may include a proximity sensor that activates the arms 164, 166 when the first side 116 contacts the tree 200. In this manner, the retention assembly 162 facilitates an attachment of the device 100 with the tree 200 from the ground. The hunter 300 can then attach the latch 192 to the hunter's harness 193 while still on the ground, and the retention assembly 162 maintains stability while the hunter 300 makes the first climb. After climbing the tree stand 400, the hunter 300 may further attach the device 100 using the holder 106 as explained previously.
[0032] As the latch 192 is connected to the cable 550 and the retracting device 500, the hunter 300 is protected from sudden fall during hunting. In a scenario, the hunter 300 may lose contact from the tree stand 400 or ladder and fall towards the ground and a speed of reeling out of the cable 550 may reach above a predefined rate corresponding to threshold speed of shaft 522 before the hunter 300 hits the ground. In such a case, the reeling out of the cable 550 is stopped due to the brake applied by the locking assembly 512 owing to the engagement of the levers 540, 542 with the ratchet wheel 544. Therefore, the hunter 300 is prevented from hitting the ground and protected from falling. In practice, the retracting device stops a two-hundred-pound hunter free falling before one foot of cable is unwound, and preferably in under six inches of free falling. After the cable 550 is stopped, the hunter may climb back onto the stand or ladder. In another embodiment, after the cable 550 is stopped, an electric motor may automatically engage, and first wind the shaft 522 back up enough to allow the levers 540, 542 to return to respective initial positions, and then slowly reel out the cable 550, at a rate of between 1 and 5 feet per minute, for example. In this manner, the hunter 300 reaches the ground safely. In a further embodiment, the device 100 may be equipped with a microphone and after the detecting a fall, by the shaft 522 locking and a torque over a certain limit on the shaft 522 being detected by a sensor over a certain limit of time, for example, and wait to detect if the hunter states a key word or phrase such as release, and then unlocks the shaft 522 and lowers the hunter to the ground. In other embodiments, the device may just wait for any noise from the suspended hunter over a certain decibel level, such as 60, 65, 70, 75, 80, 85, or 90 decibels, for example. Therefore, in normal use, the retracting device 500 reels in cable 550 as a hunter 300 climbs the tree 200, and allows for the cable 550 to reel out from the housing 102 at a slow rate i.e. below the predefined rate (threshold speed) as a hunter moves about or descends a ladder, but automatically stops the reeling out of the cable 550 if a rate (speed) of reel out of the cable 550 exceeds the predefined rate.
