Abstract: An arrow having a shaft that has a forward end, an oppositely disposed rearward end, a central axis and a plurality of axially elongated vanes mounted to the shaft contiguous the oppositely disposed rearward end thereof. Each vane of the plurality of axially elongated vanes has a planar portion tangentially attached to the shaft and an extended fin portion projecting from the planar portion in a direction away from the central axis of the shaft. The undersurface of the extended fin portion defines an air channel for channelling air flow along the undersurface of the extended fin portion to generate a rotating moment about the central axis of the shaft to provide increased rotation and increased stability to the shaft and improve flight accuracy of the arrow.

Abstract: An archery training device for teaching an archer proper muscular control, muscle force and body positioning before, during, and after release of an arrow for promoting accurate shooting of the arrow with a bow. The archery training device promotes a push-pull balance between the archer's string arm elbow and bow hand throughout the shot while also providing feedback of this balance when shooting arrows. The archery training device includes a string arm connector which is securable to the string arm elbow and a bowstring connector that is secured to the bowstring. An inelastic cord-like force carrying member extends between the string arm connector and the bowstring connection which creates a predetermined slack in the force carrying member when the archer is in the full draw position. Upon full release of the bowstring by the archer's fingers, the cord-like force carrying member becomes taut and instantaneously transfers the tensional forces to the upper body of the archer.

Abstract: A bowsight is provided for an archery bow including a support bracket for attachment generally parallel to the length of the archery bow. A plurality of sights are connected to and are longitudinally spaced along the support bracket. Each of the sights defines an outer longitudinal height and a smaller inner longitudinal height. The outer heights are successively smaller from sight to sight. Each of the outer longitudinal heights are positioned so that the bow will be properly aimed at a target when the outer longitudinal height of any one of the sights equals the apparent vertical height of the target. The inner longitudinal heights are successively smaller from sight to sight in the same direction as the outer heights become smaller. Each of the inner longitudinal heights are of a dimension so that the bow will be properly aimed when the inner longitudinal height of any one of the sights is equal to the apparent vertical height of the target.

Abstract: A height adjustment mechanism for a vehicle seat cushion which permits selective vertical adjustments of the forward and the rearward portions of the seat. The seat support includes fore and aft brackets which extend downward from the seat cushion and are attached in a pivotal manner at their lower ends to outboard ends of link arms. The link arms extend in the fore and aft direction from a central location where they are pivoted about a common axis and supported by a stationary support or bracket means. Interaction between pins carried by the arms and vertically toothed sector means formed in the stationary bracket positively locates the arms in a preselected vertical position. The arms are movable within a range determined by the extent which the pins are free to move in the toothed sector or slotted apertures.

Abstract: A combination of a bow and power handle, the power handle will isolate an archer's hand from the bow in order to prevent the archer's hand from effecting the position of the bow which would, in turn, change the direction of the arrow. In addition, the instant invention adds energy to the bow in order to increase force to an arrow which increases the flight distance when the arrow is launched. The assembly includes an archery bow having limbs interconnected by a bowstring which is movable to a drawn position to impart energy to an arrow upon release of the bowstring from the drawn position. A power means is formed from a connecting portion and a biasing portion and includes a suitable handle.

Abstract: An archery arrow comprising a shaft having a circular cross section with a forward end and a rearward end. The improvement comprises a vane system adjacent the rearward end of the shaft for stabilizing the flight of the arrow. The vane system comprises first and second vanes disposed diametrically opposite one another on the vane shaft. Each vane is defined by an integral member having an aerodynamic fin extending tangentially from one side of the shaft and supporting the vane so that the vane is spaced from the shaft, the spacing between the vane and the shaft decreasing from the forward end of the vane to the rearward end thereof so as to define a pocket between the vane and the shaft of decreasing volume from front to rear to create pressures upon the vane and the aerodynamic fin to cause the arrow to rotate.A hunting arrowhead is also disclosed. The head includes two identical halves.

Abstract: An arrow comprising a shaft with forward and rearward ends. An integral plastic vane member extends along the shaft adjacent the rearward end and includes first and second vanes spaced from the shaft by a pair of spaced generally parallel support vanes. The support vanes are interconnected by a base portion which may take one of various configurations for engaging the arrow shaft. The first and second vanes are generally triangular in configuration and are planar; however, one of the first and second vanes is disposed so as to angle downwardly from the front to the rear relative to the shaft while the other vane is disposed to angle upwardly from front to rear relative to the shaft to induce rotation of the arrow shaft during flight. The support vanes can also be spiralled to induce rotation. Thus, the first and second vanes and the first and second support vanes provide four vanes from one integral piece of plastic and all of which perform an aerodynamic function.
