Abstract: A game apparatus including an obstructing member connected to a target member. A front side of the target member lies substantially in a first plane. The front side of the target member has an area on the first plane. The obstructing member is rotationally supported by a supporting means; wherein the obstructing member is configured to rotate with respect to the target member; and the obstructing member is configured such that, when the obstructing member is in the first orientation with respect to the target member, a projectile having a sufficient velocity and mass striking a particular area of one of the protruding pieces will cause rotational movement of the obstructing member toward the second orientation so that another projectile propelled toward the front side of the target member can reach a portion of the front side of the target member that is not obstructed by the obstructing member.

Abstract: A puzzle including a background puzzle surface having printed thereon a background puzzle image including image areas and blank areas, and at least one puzzle piece formed of a transparent material having printed thereon a puzzle piece image including image areas and blank transparent areas. When solving the puzzle, the at least one puzzle piece is superimposed over the background puzzle surface and is moved thereon to a correct location in which the image areas of the background puzzle image together with the image areas of the puzzle piece image match and form a cohesive image.

Abstract: A rolling toy to be rolled on a horizontal support surface, for instance, on a floor, having a primary roller and a secondary roller. The primary roller having a tubular-like member extending along a longitudinal axis and at least one annular flange fixedly attached to the tubular-like member and extending outwardly therefrom. The secondary roller is adapted a for rolling motion upon an interior surface of the tubular-like member when the primary roller rotates about the longitudinal axis due to the rolling motion of the rolling toy on the horizontal support surface. At least one of the following includes a helical guiding means: (i) the tubular-like member and (ii) the secondary roller. Thereby, when the secondary roller is disposed on the interior surface of the tubular-like member and the primary roller is set in a rolling motion on the horizontal support surface in a predetermined direction, the rolling motion of the primary roller results in a tilting of the latter.

Abstract: An exercise device includes a housing having at least a wall portion, at least two apertures extending through the wall portion and spaced from each other, and at least one elongate rod having a center section located between opposite ends. The center section is adapted for slidable movement through the apertures. The friction generating arrangement provides frictional engagement of the elongate rod with the apertures, so as to resist sliding movement of the rod through the apertures.

Abstract: A hand exercise device comprises a hollow housing with a plurality of apertures extending through its outer wall. Exercise rods extend from the interior of the housing and through the apertures. The rods may have an enlarged section with a cross dimension that is greater than a cross dimension of the apertures for retaining the rods in the housing. Filler material is located within the housing interior. The filler material comprises a plurality of solid particles in frictional engagement with the portion of each rod within the housing to thereby resist sliding movement of the rods when they are either pushed or pulled by a user. Several different embodiments of the hand exercise device are disclosed.
