Patent number: 4657100Abstract: This invention concerns a portable golf cart. It includes two wheels which support an axle upon which is mounted a main horizontal frame. An elongated bag support frame for holding the golf clubs is connected to the frame by a pivot connection so that the bag support frame can rotate from one position where it is essentially perpendicular to the horizontal frame to a second position where it is in alignment with such horizontal frame. The bag support frame can be locked in either position. The bag support frame itself is made of at least two sections that are pivoted with respect to each other so that they can be in an extended position or one section can be folded over the other so as to form a compact golf cart when the bag support frame is in its folded position and is rotated into alignment with the axle.Type: GrantFiled: December 6, 1985Date of Patent: April 14, 1987Inventor: Andrew R. Lewis

Patent number: 4460189Abstract: A portable multi-directional hand truck A is illustrated including a frame 10 having a toe plate 14 and a pair of rear indexing wheel assemblies B. Indexing mechanism D is connected between the frame 10 and a contoured wheel C in each wheel assembly having a first position in which wheels C are aligned for forward movement and a second position for movement transverse to the forward movement. Wheels C include a contoured surface 54 for forward movement and a rounded contoured surface 56 for transverse movement. Surface 56 provides a rounded support surface over which the load may be broken and transported in which configuration the load is supported in a raised position for transporting long loads transversely down narrow passageways without dragging and sagging ends of a long load.Type: GrantFiled: May 24, 1982Date of Patent: July 17, 1984Inventor: Frederick Goff
