  • Patent number: 6095333
    Abstract: A bucket that children cannot put over their head, having a bottom wall, side walls, a removable lid and a non-pivoting U-shaped handle. The side walls project upwardly from the bottom wall and form an opening having circumscribing edges. The removable lid fits in the circumscribing edges for closing the bucket. The non-pivoting U-shaped handle has opposite side legs slidably mounted onto the side walls. The U-shaped handle also has stopping means for limiting sliding of the handle between a first position where the U-shaped handle bears against the lid when the same is fitted in the circumscribing edges and a second position where the U-shaped handle extends away from the lid and thus makes it possible to remove the lid from the circumscribing edges. Thus, the U-shaped handle, both in first and second positions, divides the opening into two smaller openings which are smaller than a child's head, thus children cannot put the bucket over their head.

  • Patent number: 5779515
    Abstract: A base for a modular multi-part construction toy is disclosed which has a surface which permits the assembly of a number of toy modules thereon to form an erected toy. The base further includes a number of mechanically movable elements which are used in association with various drive shaft pieces to rotate or otherwise move part or all of the erected toy. The drive shaft pieces are engaged by the movable elements which in turn are driven in movement by gearing mechanically coupled to a motor which is housed internally within the base. The base further includes a number of electrical receptacles for supplying electric power to electric light emitting toy modules, and an audio output mechanism for producing sounds associated with the erected toy. The surface of the base may further be provided with a desired contour or profile and have indicia which simulates a particular geographic location, vehicle, vessel, or other structure.
