Abstract: A heating and cooling apparatus is disclosed that combines a PTC heating element with a fan, and a combination of a cooling device aided by a thermoelectric cooling device to provide heating, passive air conditioning, and air circulation. The heating and cooling apparatus can include a condensation trap, a collection container, and an ozone generator for collecting and purifying the condensate. In addition, this apparatus provides the additional function of serving as an air purification system operating either in combination with the heating/cooling functions or as an independent air purifier.

Abstract: A dumbbell assembly having a dumbbell. The dumbbell has a center grip disposed between and connecting a pair of weight retaining spools. Each spool has an outer sidewall and a plurality of spaced apart radial flanges extending from the sidewall. An area between adjacent flanges on a single spool define a weight retaining facet. The dumbbell assembly further includes a toroidal shaped weight made from flexible material. The material forms a pocket which is filled with granular material. The weight is adapted to fit over the flanges and engage the facet.

Abstract: An exercise bench assembly having at least one leg block and a platform. The leg block has a pair of opposing laterally directed projections and the platform has a pair of projection receiving slots for respectively receiving the projections so that the platform can be supported by the leg block. The projections and the projection receiving slots have cooperating arcuate shapes to allow rotation of the platform with respect to the leg block.

Abstract: An improved baseball game that is played by two or more players within a limited space in a room that closely simulates real baseball. One player manipulates a bat which is pivotally mounted on a base that is located within a transparent enclosure and attempts to strike a ball propelled by a hand manipulated wand operated by another player at a pitching station located outside of the enclosure. The balls move through an opening formed in an end wall of the enclosure and down an inclined surface toward the bat. A backstop will signal whether an unbatted ball is a ball or strike. A ramp within the enclosure directs a batted ball toward a plurality of ball receiving compartments which designates whether a hit or out has been achieved. A transparent shield is located at the pitching station for protecting the pitcher from being struck by a batted ball passing through the opening in the end wall of the enclosure.
