Referring now to FIG. 1-12, the present invention features a novel arm guard system.
Introduction:
Arm guards for the sport of archery have been used for years to protect archers from the trauma of a string striking the arm. When the string strikes the arm, lacerations, contusions, or abrasions may result. Modern materials have led to a number of different designs, but none have been completely successful at protecting the arm. Additionally, when the bow string strikes the armguard, string movement and harmonics are affected with the net result of affecting arrow flight and making arrows inaccurate and inconsistent.
Devices designed to protect the arm in addition to affecting arrow flight may also accelerate string breakdown and failure because of friction related damage.
Here, we introduce a new armguard design that is novel in shape and materials. It is designed to protect the arm from traumatic damage, to reduce the effect that an arm strike has on arrow dynamics and flight, and to protect the string from damage.
Problems with Existing Designs:
Arm Protection:
A number of designs have been manufactured to try to protect an archer's arm from the trauma of a string strike. Simple sleeve style armguards can protect the arm but can be bulky and may not conform to the arm properly due to thickness or rigidness; they may result in an increased number of arm strikes because of the nonconformity. Partial coverage armguards may protect the arm but again do not conform well to the arm during shooting because of the rigidness of the armguard and movement of the arm during shooting.
A typical mode of arm injury in spite of arm guard installation occurs when the string strikes the proximal end of the arm guard and the string moves under the arm guard hitting the arm and causing injury. Current arm guard designs have a proximal end with a straight or convex design that allows an undesired capture of the bow string.
Placement of retaining straps distal from the proximal end of the arm guard can compound the string capture problem, resulting in more traumatic damage to the arm. The solution to the string capture problem is to change the shape of the proximal end of the armguard to a concave shape and to place the restraining strap in close proximity. When the armguard conforms to the shape of the arm, it develops an arc-like cross-section with a sloping concave proximal end. As the bowstring strikes the end of the armguard, it is guided onto the surface of the armguard instead of striking the end of the arm guard and displacing it as would happen with a straight proximal end or being guided under it as would happen with a convex or straight proximal end.
Hence the first novel feature of the design: the arm guard has a concave proximal end with closely adjacent retaining straps that allows the string to be guided onto the surface of the armguard when the string strikes the end of the arm guard.
Friction generated when the string strikes the arm and protection of the string:
The second feature of the armguard is the material from which it is made. When a bowstring strikes an armguard, the string direction, speed, and harmonics are affected. The result is an inaccurate arrow that may miss the target or create inconsistency in a series of arrows. Use of a low friction polymer such as but not limited to polytetrafluoroethylene (PTFE, e.g., TEFLONTM), fluorinated ethylene propylene, and perfluoroalkoxy, and silicone rubber allows the arrow to strike the arm guard with a minimal effect on arrow flight. Additionally, tests have demonstrated that the low friction material guards against wear on the bow string resulting in a longer lasting string.
The arm guard may be made from solid low friction polymer sheet or tube, or may be low friction polymer bonded to cloth, leather, or other material. Additionally the polymer may be used as a coating on cloth, leather, metals, or other materials. The low friction polymer may also be expanded and breathable such as expanded PTFE. Additionally the armguard may be incorporated into clothing such as sleeves of shirts or jackets by stitching, coating, or direct incorporation into clothing fibers.
Lack of Conformity to the Arm:
Thick armguards may not conform to the shape of the arm, especially when the arm moves as the bow is raised. Thus, the third feature of the armguard is its' thinness. The arm guard may be made of low-friction polymer sheet in a thickness ranging from 0.0005 inches to 0.5 inch. The thin and flexible material allows for better conformity to the arm and decreases the likelihood of an arm strike. This may result in a decreased likelihood of arm damage or aberrant arrow flight.
The preferred embodiment of the armguard uses a thickness of 1/32′′.
Finger Tab:
The purpose of the finger tab is to protect the fingers from frictional forces generated when the string is released. Traditional finger tabs are constructed from leather with/without a metal base and have a finger spacer. The new design has a layer of PTFE or other low friction material that contacts the string and minimizes string-finger friction. Testing reveals that arrow velocities are faster compared to a traditional finger tab, resulting in a flatter trajectory, shorter travel time, and more accurate shot.
PTFE Coated String Release:
A release device is used in compound archery to achieve a more accurate shot. The device consists of a hinged hook to hold the string. The hinge is allowed to swing, resulting in a release of the string or string loop. The new device focuses on the metal or plastic hook that holds the string or string loop. In the new release, the release is coated with PTFE or is created from PTFE, allowing increased arrow velocity, flatter arrow trajectory, and a more accurate shot.
Chest Guard:
The chest guard is used to minimize interaction between the string and clothing or tissue. Constructing a chest guard from low friction materials such as polytetrafluoroethylene (PTFE, e.g., TEFLONTM), expanded PTFE, fluorinated ethylene propylene, perfluoroalkoxy, or silicone rubber.
Summary of Novel Features:
An archery arm guard with a concave shaped proximal end with adjacent restraining straps to reduce the risk of arm strikes. An archery arm guard made of a low friction polymer such as PTFE. This may be an expanded material, fused material, coating, or direct low friction fiber construction. An archery arm guard made to be thin and flexible to allow conformity to the arm. The armguard may be independent or incorporated into a shirtsleeve, jacket, or other article of clothing.
