Abstract: A yo-yo with an axle having two side-by-side bearings constituting a double bearing that enhances yo-yo performance characteristics by improving balance and reducing unwanted effects such as wobble, tilting, twisting, vibration, and string friction. Each bearing having an outer ring, an inner ring, and an array of balls trapped in tracks between the two rings. The outer rings of the bearings may be beveled to form a groove to enhance stability and centering of a string. Alternatively, the bearings may be covered with a bridge that has a straight outer surface or has an outer surface with a groove that could take several shapes. The bridge may have an internal ridge that acts as a centering mechanism for the bearing and bridge assembly. The inner and outer rings of the bearings may be independent or shared, and the rings of one bearing may overlap the rings of the other bearing. The inner rings of the bearings may be extended outward to provide spacing between bearing parts and yo-yo side walls.

Abstract: A portable bucket for carrying baseball equipment (such as bases, gloves, balls) that is attached to a pitching target. The bucket, a bottom mounting bracket, a top mounting bracket and an extendable frame provide support for the pitching target. The pitching target can be folded and snapped to the lower mounting bracket when the invention is being carried. The target is positioned for play by fully extending the frame, unsnapping the pitching target from the lower mounting bracket, rotating it, unfolding it, and then fastening it to the extendable frame. Also attached to the bucket could be tubes for carrying baseball bats or holding a tee for tee-ball, or wheels to assist in transport.

Abstract: A yo-yo wherein each half body has three essential elements: a axle/hub assembly, a rim, and an interior space containing flexible, compressible material, such as an elastomer or a bladder filled with gas, liquid, or gel. The axle/hub assembly and the rim contain the flexible, compressible material but are not rigidly in contact with each other. In this way a shock to the rim and vibrations to the string are suppressed and dampened by the flexible, compressible material. For greater flexibility and shock damping, there could be cavities (grooves or holes) in the elastomer material or for greater lateral stability, the rim could overlap the gaps between it and the axle/hub assembly. There could also be containment/alignment walls extending into the flexible, compressible material or O-rings in gaps between the rim and the axle/hub assembly.

Abstract: A rotatable toy in which a light emitting diode, positioned in one of the body halves, is connected to a solid state control circuit which includes a timer to periodically energize the LED and produce a stroboscopic effect.
