The present invention relates to a safety restraint device, and more particularly, to a safety harness used by hunters to prevent accidental falls when using a tree stand.
It has been quite popular with hunters to utilize tree stands or platforms above the ground to aid in hunting. In order to prevent individuals from falling from elevated platforms, such as tree stands, a number of different types of safety devices have been developed. One example of a safety device is a harness that is attachable to the tree or other support on which the individual is standing. If the individual happens to fall off of the platform, the harness, because it is attached to the support, operates to stop the fall of the individual after a short distance in order to prevent the individual from striking the ground.
While many prior art harnesses engage to stop the fall of an individual, the harness exerts an instantaneous and significant force on the body of the individual in a direction directly opposite to the direction in which the individual is falling. The magnitude of this force can often cause injury to the individual depending upon both the size of the individual and the length of the fall traveled by the individual, i.e., the momentum of the individual, before the engagement of the harness. Even after the fall the individual is now hanging from their harness but has no way to pull themselves back up onto the platform they feel off of which in a short period of time hanging from their harness in this manner could cause them to die from suspension trauma. In addition, some prior art safety harness can sometimes suspend individuals in other than an upright position, which is not desirable for obvious safety reasons.
In addition to stopping the fall of an individual, it is desirable that the safety harness, when engaged, suspend the individual in an upright position for obvious safety reasons.
The present invention offers an improved safety restraint device that fills a need in the art for a simple, effective, inexpensive, easy to use device which is not hampered by noise or lack of flexibility of movement. The present safety system when worn facing the tree such as a climbing belt better absorbs the shock of a fall and when engaged, suspends the individual in an upright seated position. If so desired the present invention can be worn as a climbing belt or it can also be worn as a traditional 6 point safety harness. The difference between the present invention and today's safety harnesses is in case of a fall that the present invention allows you to pull yourself up when worn and used properly. The anchor member and connecting member of this invention could also be incorporated and used with the prior art harnesses used today for added safety reasons that may prevent individuals from dying from suspension trauma.
The present invention generally relates to a safety restraint suitable for restraining the hunter to a tree in a deer stand or user to a pole. The safety harness of the invention comprises a
A major difference between the harness of the invention and prior art harnesses is that with the present harness it is preferable that the hunter be facing the tree, not with his back to the tree as you are with many of the harnesses sold today, but this harness could also be used as a 6 point safety harness if so desired.
The invention relates to a safety restraint device of a configuration and shape particularly suitable for use by hunters in treestands, wherein the device is used to secure the user to the tree so that the user may move about freely without fear or possibility of falling from the stand. Those skilled in the art will recognize that treestands are typically utilized approximately 10 to 25 feet above the ground thereby inducing anxiety of falling or inadvertent falls. As those skilled in the art will recognize, treestands are well known in the art and therefore, will not be described further herein.
The anchor member (2) is connected to a tree or other suitable object. The anchor member (2) strap is generally 1 to 4 inches wide, and attached thereto is a round or oval ring approximately 3-5″ (4) in diameter and a D-ring (13) is attached approximately 3.5″ from the round or oval ring (4). The strap has a buckle on one end and on the opposite end it has a round metal grommet about 1″ from the end. The 3″ round/oval ring and D-ring are attached/sewn in such a manner that the strap first goes through the rings and then approximately 12-15″ of the strap is threaded through a buckling means. This 12-15″ of strap is then doubled through the buckle and is sewn with approximately a 2-4″ opening that starts approximately 4″ from end of buckle that the 3″ round ring is contained therein. The ring/rings are sewn such that the ring/rings are pulling against the main strap and not the 15″ sewn portion. The D-ring is sewn with a very tight opening to fit the D-ring so it cannot slide. By having the round ring sewn directly to the strap in this manner, there is only a 3″ opening or so, which does not allow the ring to slide freely on the main strap. See
The D-ring that is sewn to the anchor strap serves multiple purposes. First, it can be used as a place to attach a connecting means such as a spring snap hook/carabiner with an adjustable knot that is attached to one end of a rope or wire and attached on the other end of this rope or wire is a connecting means such as a carabiner which is attached to the end of the anchor member strap by means of a round grommet about 1″ from the end of the strap. If carabiner is not used to connect to end of strap this end could be tied through metal grommet with proper knot. This is used as a safety feature so the end of strap on the anchor member cannot accidentally be pulled back through the buckle. Second, this is a place where a connecting means such as a spring snap hook or carabiner is attached to a length of rope by an adjustable knot and is connected to the D-ring on one end and the other end is connected to the user member waist strap. This acts as a secondary safety device in the event that the primary safety strap through the round ring fails.
The D-ring is also a place where the connecting member could be connected to by means such as a rope, which on one end has a carabiner and pulley hoist connected to the D-ring and the other end of the rope is attached to the end of the connecting member strap through the round grommet at end of connecting member by means such as a prusik knot and carabiner. Those skilled in the art could see how this anchor member and connecting member could be incorporated with today's harnesses for added safety reasons.
The user member is generally a belt type fastener which has two separate main straps or webbing approximately 2″ wide, which are attached to a wider foam waist belt. One strap approximately 64″ long is attached to user member foam waist belt and goes around the waist of the user and is attached by means of a buckle or 3 bar slide that is attached to the side of user member foam waist belt, which will allow for adjustment. The second strap is another approximately 2″ wide and 74″ long piece of strap or webbing that is attached also to the foam waist belt. This second strap runs from one side of the waist belt and across the users back to the other side, then the strap runs through the 3″ round ring on anchor member that is attached to the tree or pole and is then threaded through a buckle or 3 bar slide which is attached to the side of the user member waist belt. This will allow the user to make the proper length adjustment as compared to the size platform or device that the user is standing on. The user can now lean back against the foam waist belt, which should be a minimum of 4-6″ wide but can be wider. With this belt now around the user's waist and through the round ring to support the user the user can now move from side to side or up and down in a smooth, quiet motion not worrying about the strap making noise as he or she moves. This design will now allow for safe and controlled movement as the user moves from side to side. As you can see if the round ring was allowed to slide freely on the main strap around the tree or pole as the user leaned or moved from side to side he or she could be thrown from the pole or tree. This design creates a V shape as the belt goes around the user's waist and hip area and through the round ring, allowing for smooth, quiet and safe operation. This user member has a 4-10″ tether located in the center of the waist belt, for safety reasons. An advantage of having a large round ring attached to the anchor member strap is in event that the user fell from the device or platform he or she was standing on the larger round ring would allow the user a place to grab and pull them self up. This round ring would also allow a place to attach the connecting member to in case of a fall. In some cases this may actually save the users life in that it allows the user to avoid suspension trauma by pulling themselves up thus relieving the pressure put around there legs from the leg straps on most harnesses today.
The user member can also include a sling or seat-like attachment approximately 5-10″ wide and 32″ long that can suspend the hunter in a seated, upright position in the event of a fall. In this design, the lower seat strap/attachment is connected to the main waist belt by means of a buckle/3 bar slide on one side for adjustment. The user member may also have optionally two leg straps attached to it that will go around user's legs. The leg straps are sewn to each side of waist belt. The straps go around each leg and are crisscrossed through the crotch area and then are fastened to a buckle or fed through (2) D-rings or 3 bar slides that are attached on each side of waist belt also. This crisscrossing of these leg straps is very important in case of a fall. This lower sling or seat-like attachment does several things. First it allows the user to sit down on the lower seat allowing the user to relieve stress on the leg and back muscles. This kind of design also allows the user more freedom and quiet movement than if the waist belt and lower seat were all one piece. Another reason for this lower seat would be in case the user fell from the platform or device he or she was standing on. In case of a fall this lower seat with the leg straps properly crisscrossed would not allow the user to fall to the ground. Most importantly in case of a fall the user would now be facing the tree or pole and in a seated position. Being in a seat position plus having the round ring to grab hold of for support if needed would decrease the chance of death from suspension trauma and would not be as likely to happen as it is today with many harnesses on the market today
The user member could also have optional shoulder straps with tethers attached which could allow the harness to be worn as a 6 point safety harness also, if so desired. The tethers and shoulder straps would be approximately 2″ wide webbing which would be attached to the user member waist strap and or waist belt. This could be done by open loops on all ends and by using a buckle/3 bar slide for adjustment. In one embodiment there are two tethers where in the first tether is a traditional tether, which is approximately 24″ long, from where the shoulder straps separate. This tether is where the strap that would connect the harness to the tree or pole would be connected. There would also be a second shorter tether 5-12″ long, which would be used for safety reasons. In case of a fall by having a length of rope with a connecting means on each end such as a carabiner and prusik knot on one end attached to the short tether and on the other end a snap hook or carabiner connected to a small pulley hoist which then could be connected to the anchor members round ring or D-ring. The user could now pull themselves up which would prevent the user from dying of suspension trauma.
The connecting member is a separate strap approximately 3-6″ wide and approximately 30″ long that is optionally wider in the middle, with one end attached in the middle of the waist belt and or waist strap. This could be attached to the front or back side of waist strap. Said strap may also have an optional D-ring attached also. At the other end of the strap is a round metal grommet located in the middle of the strap and approximately 1″ from the end of the strap. Attached to this metal grommet is a cord, or rope that is approximately 3-6′ long or longer. Attached at one end of this rope is a pulley hoist with a connecting means such as carabiner or snap hook connected to the D-ring or round ring that is attached to anchor member and the other end has an adjustable knot, such as a Prusik knot with a carabiner attached to a round grommet at the end of the connecting member. With the connecting member attached in this manner it can act as a seat and possibly prevent a fall. In case of a fall, if the connecting member was not already attached to anchor member before the fall, given the proper length of rope and with the connecting devises mentioned previous the rope could be run through the users legs or around both legs and connected to the round ring or D-ring which are connected to the anchor member, which is attached to a tree or pole. Once this connecting member strap is attached to the anchor members round ring or D-ring the user can then pull the rope through the pulley and carabiner system (pulley hoist) or prusik knot. By pulling them self up in this manner this connecting member strap will help cradle the user into more of a seated position. By being able to use the connecting member and anchor member in this manner would again help prevent the user from dying from suspension trauma if they fell from the platform they were standing on.
One of the major problems today with many of the harnesses sold in the market is that if the user were to fall from a treestand, the harness might initially save the users life by preventing the user from falling to the ground, but if the user has no means to pull him/her self up, they could die from suspension trauma in as little as 30 minutes. With the design of the present invention, this would not happen in that the user has several possibilities to pull them self up. More particularly, a major advantage of the design of the present invention compared to many other designs is that in the case of a fall, the risks of dying from suspension trauma are greatly reduced. With the present design when used properly the user would not fall straight down and hang from your harness; rather, the user would fall forward into the tree or pole, thereby facing the tree or pole in a somewhat seated position. With the round ring to grab hold of and help pull yourself up to situate your weight the user now can shift his or her weight around and sit in the harness until help arrives. If used properly the connecting member used in conjunction with the anchor member as stated above could be used as an accessory to many of the harnesses on the market today. These 2 members could help prevent death's that are occurring today from suspension trauma when a user falls from the platform they were standing on.
While the present invention will be described with respect to a preferred configuration of the device, and with respect to preferred materials and shapes of construction, it will be understood that other configurations, materials, and shapes could be used for constructing the safety devices, without departing from the spirit and scope of the invention. Various advantages and features of novelty which characterize the invention are pointed out with particularity in the claims annexed hereto and which form a part hereof. However, for a better understanding of the invention and its advantages obtained by its use, reference should be made to the drawings which form a further part hereof and the accompanying descriptive matter in which there is illustrated and described a preferred embodiment of the invention.
Referring to the drawings, wherein like numerals represent like parts throughout the several views:
As shown in
The user member (1) is preferably in the form of a waist belt (5) approximately 5-10″ wide that is formed around the users waist and made of a suitable material, such as polar fleece, foam, nylon or canvas, among others, and that can include a separable closure. Attached to and around the foam waist belt are 2 separate pieces of webbing/waist strap (1a) and ring strap (1b) attached on top of each other, This will form a belt like loop. The end of waist strap (1a) is to be placed around the user's waist as shown in
Another alternative is to have a single strap (8) attached about the middle of the back by an open loop on the end of strap (8) which will form a half hitch knot around straps (1a) and (1b) which are on waist belt (5) user member (1). Strap (8) will come up approximately half way up the user's back and then separate into two shoulder straps (7). These shoulder straps are then run over the shoulder. These shoulder straps are not sewn to the waist belt instead they have open loops (9) on them in which the waist belt (1a) runs through these open loops and is then attached to some type of fastening means, for example, a buckle (6a). On these shoulder straps (7) are 3 bar slides (20) that allow the user to make length adjustments on these straps. By not permanently attaching these shoulder straps to the waist belt it will allow this harness to fit a wider range of waist sizes that the users may have.

In operation, the device is used in the manner generally shown in
Because the user is secured to the tree or other object, he or she may lean back or to the side and take aim at game which would not be possible without restraint. The device offers advantages for bow and rifle hunters as well as observers and photographers who wish to prevent an accidental fall. This invention also has the ability to be used as a six-point safety harness. See
It is believed that the invention, its mode of operation, construction, and assembly and many of its advantages should be readily understood from the foregoing without further description.
