Abstract: Shooting accuracy in archery may be greatly improved by increasing the precision and repeatability in which an archer establishes “anchor points,” which are contact points between the archer and a drawn bow and arrow at a moment of launch. One such contact point is the hand gripping the bow grip. The invention provides a bow grip aid which enables an archer to repeatably grip the same location of the bow grip and maintain consistent grip firmness from one shot to the next. Reducing variances of this aspect of the archer's form benefits the archer by reducing variances between the archer's sighting process and determination of point of aim, and the impact point of the arrow on its target. The invention helps archers grip a bow more consistently so they can consistently place each arrow where they want it to go.

Abstract: A golf club head comprises a sole, a recessed sole port in the sole; and a rotatably adjustable sole piece adapted to be at least partially received within the sole port and comprising a central body having a plurality of contact surfaces adapted to contact the sole port and being offset from each other along a central axis extending through the central body of the sole piece. The sole piece can be positioned at least partially within the sole port at five or more rotational and axial positions with respect to the central axis, wherein at each rotational position, at least one of said contact surfaces of the central body contacts the sole port to set the axial position of the sole piece. The sole port and/or the sole piece can be generally pentagonal in shape.

Abstract: A hop-up device for an airsoft gun allows a user to adjust the tension applied to a BB during the chambering of the BB in the airsoft gun. The hop-up device has an adjustable tension adjustment sleeve configured to constrict a desired amount around the BB. The tension adjustment sleeve provides tension on the BB when the air nozzle is seating, or chambering, the BB in the bucking lips of a rubber bucking prior to firing. By adjusting the tension adjustment sleeve, the user can increase or decrease the bucking lip tension on the BB to reduce or essentially eliminate the adverse effects from manufacturing tolerances, wear, and the like. These adverse effects can cause double feeding of the BBs, jamming, inconsistent firing, slow firing, midcap syndrome (the feed spring in the magazine is too strong and forces BBs against the air nozzle with excessive force), and the like.

Abstract: A toy gun having a pair of sides are joined together using a number of pins inserted through pin holes passing through the pair of sides. A trigger and a slide are sandwiched between the pair of sides and are secured therein. A pivot pin allows the trigger to be pulled rearwardly such that it presses against the slide, moving it reward as well. When this occurs, the slide moves out from between the two sides, pushing the elastic bands away from static notches located on the rear end of the sides. This causes the top-most elastic band to fire away from the gun, and the remaining elastic bands to be reseated upwardly into the next adjacent respective static notch. The elastic bands pull the trigger back into its original position, allowing for semi-automatic firing.

Abstract: The present invention provides a putting guide capable of correcting a posture when putting, checking a contact angle between a putter and a golf ball, correcting a posture of an exerciser during a putting practice, and checking a focusing point that the exerciser watches.

Abstract: A repeating crossbow having a pump-action reloading mechanism. The crossbow includes an elongated body with a shooting track and a holding chamber configured to house one or more projectiles. A hatch is coupled to the body and configured to move between a first position aligned with the shooting track and a second position at least partially aligned with the holding chamber. A palm rest is slidingly connected to the elongated body. Sliding the palm rest in a rearward direction causes the hatch to move from the first position into the second position. A biasing member within the holding chamber ejects a projectile onto the hatch. Sliding the palm rest in a forward direction to return to its default position causes the hatch to return to its first position, bringing the projectile into alignment with the shooting track.

Abstract: A single-shot/repeating switching device is provided for a toy gun that includes an outer casing, a bolt seat, a trigger link, and a trigger section. The single-shot/repeating switching device includes: an adjustment hole formed between the outer casing and the bolt seat, an adjustment seat having a toothed rail, a pinion rod rotatably arranged on the toothed rail, an operating portion arranged on the pinion rod and extended to outside of the adjustment hole, a coupling portion formed on the adjustment seat and opposite to the toothed rail, and a movable arrestor joined by a joining part to the coupling portion. A user may push, from the outside the operating portion to cause corresponding motions of the pinion rod and the toothed rail so as to drive the movable arrestor by means of the adjustment seat to selectively block a movement of the trigger link for efficient single-shot/repeating switchability.

Abstract: Golf clubs and golf club heads having a weight member that is configurable in multiple positions to alter the performance characteristics of the golf club head are presented. In some examples, the weight member may be arranged in a sole of the golf club head and may include ends having different weighting characteristics. For instance, one end may be heavier or denser than another end of the weight member. The difference in weight characteristics may be due to different materials used to form the different ends, different construction of the ends, and the like. The position of the weight member may be adjusted to alter the performance characteristics of the golf club head. For instance, the weight member may be removed and rotated to position a heavier end where a lighter end was previously positioned.

Abstract: A break action pistol crossbow having a repeating capability. The crossbow has a loading chamber configured to house a plurality of bolts. A biasing mechanism is disposed within the loading chamber. The crossbow has a forward retainer positioned at the front of a flight rail and a rear retainer positioned at the back of the flight rail. The bowstring is configured to be drawn over a bolt loaded into the chamber. As the bowstring travels over the bolt, the biasing mechanism presses the bolt against the bowstring.
