Abstract: A ball rolling unit for fun to initiate vision and hand coordination for pre-school children includes multiple canopies, a section of course extending downward at a certain inclination being sewn to each canopy; an inner peripheral of each course and its corresponding sides being sewn with hooks and loops of a Velcro to open or close each course; and a ball rolling upon the ball rolling unit for pre-school children standing around the ball rolling unit to roll the ball thereon by holding an edge of the ball rolling unit to pull it up and down for learning to focus on movement of an object and agile reaction of their hands in various forms of the game with each channel opened, closed, or formed into a pocket.

Abstract: A pepper grinder has a grinding assembly including an inner grinding member and an outer grinding member turnable relative to each other to grind pepper in between. The outer grinding member is secured in a lower housing member by means of a lower securing ring connected to the outer grinding member; the securing ring has saw teeth projecting from an upper edge, and is pressed into the lower housing for the pointed ends of the saw teeth to be inserted into the inner side of the lower housing such that the outer grinding member can't turn relative to the lower housing. The inner grinding member is also secured to an upper housing by a securing ring of the kind. Thus, the inner grinding member can turn relative to the outer one when the upper housing is turned relative to the lower housing.

Abstract: A rack includes a base, a supporting rod, and a hanging member. The base has opposing connecting parts on two opposing ends. The middle portions of the connecting parts define an upright cylindrical holding space in between. The supporting rod is passed into the upright holding space, and pivoted to the connecting parts at a lower end so that the supporting rod can be pivoted between a laid down position and an upright in-use position. The hanging member includes a ring-shaped supporting part pivoted to the top of the supporting rod such that it can be disposed perpendicular to the supporting rod for a bag to be hung on. The supporting rod is provided like a telescope so that the height of the hanging member can be changed to be suitable for bags of different sizes.

Abstract: A playcart movable with hands has two wheel supports each has a side wheel fitted onto it. The wheel supports are each connected to a connecting plate with two pins. The connecting plates are each connected to one of two bent ends of a front support member, and can be relocated on the front support member to change a width of the playcart for users of various bodily sizes. A main support member connected with a seat member is separably secured to the front member; the seat member can be relocated on the main support to change a length of the playcart. The wheel supports each can be pivoted inwards to fold the playcart for easy storage when one of the pins is removed.
