Abstract: A revolving sequential launching device is adapted to be used in a toy projectile launcher. The revolving sequential launching device includes a guide member and a launch unit. The launch unit includes a revolving sleeve having a guide hole, a cam rail subunit disposed on the revolving sleeve, and a plurality of second gas conduits. The cam rail subunit is movable to be in sliding contact with the guide member during movement of the launch unit such that further movement of the launch unit drives rotation of the revolving sleeve. The rotation of the revolving sleeve brings the guide hole to be sequentially aligned with the second gas conduits, thereby discharging sequentially the toy projectiles.

The gas launcher further includes a projectile housed within the launcher barrel with the bladder positioned between the first end of the launcher barrel and the projectile. The projectile is dischargeable from the launcher barrel when the bladder ruptures when gas in the bladder exceeds a pressure threshold.

Abstract: A toy launcher with a drum magazine assembly that has a rotatable drum portion mounted for rotation, with a rear plate and a central support with an opening for a support axle. A ring of projectile holders is connected to the rear plate, with each projectile holder holding at least two projectiles arranged in a generally radially stacked configuration. Generally radially extending walls are located between adjacent projectile holders. Each of the projectile holders includes a slot on a radially inner side into which a projectile biasing arm extends at a projectile launch position. A pusher is located in the housing adjacent to the projectile launch position. Drive wheels are positioned in front of the drum magazine assembly at the projectile launch position. The drive wheels are motorized so that they rotate to propel a projectile pushed from the drum between the drive wheels for launching the projectile.

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 fingers of the hand gripping the bow grip. The invention provides a torque spike as 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.

Abstract: A ball tossing device for use in playing a ball tossing game includes a rod, which is substantially rigid, a basket, which is attached to a front face of the rod proximate to an upper end of the rod, and a cup, which is positioned in the basket and which is attached to a bottom of the basket. The cup is sized complementarily to a portion of a ball to be used in a ball tossing game, allowing the portion of the ball to be inserted into and retained by the cup when the rod is substantially vertical. A rear sight is attached to and extends from the upper end of the rod. The rod can be grasped in a hand of a user, positioning the user to align the rear sight with a target and to launch the ball at the target by one or both of a flick of a wrist or an extension of a forearm of the user.

Abstract: A multi-dimensional adjustable device for use in training skiers is disclosed. The ski training device of the present invention provides a horizontal support bar having a cushioned proximal end for comfortably engagement with a skier's chest and an opposite, distal end which can be gripped by a ski instructor.
