A handle assembly for towable, wheeled luggage includes an axially elongated tubular member, which is extendably and retractably attachable at one end to the luggage, and a handgrip assembly rotatably mounted on the free end of the tubular member. A slidable collar assembly surrounds the rotational dividing line between the handgrip assembly and the tubular member and is axially movable relative thereto to permit selective rotation and locking of the handgrip assembly relative to the tubular member. The handgrip assembly may have a P-shaped configuration which is rotatable to position the loop portion of the P-shaped assembly to one side or the other to accommodate lefthanded and righthanded towing of the luggage.

1. A handle assembly for towable, wheeled luggage, comprising:a tubular member having an axis of elongation and being adapted to be connected at one end to a piece of luggage; a handgrip assembly having a handgrip portion and a base portion, said assembly being mounted on the other end of said tubular member for rotation relative thereto about said axis of elongation, said rotation occurring along a dividing line between said handgrip base portion and the axially adjacent portion of said tubular member; and a collar slidably mounted on said handgrip base portion in surrounding relation thereto for movement in the direction of said of axis of elongation between a first axial position, at which said collar is located on the handgrip assembly side of said dividing line and permits rotation of said handgrip assembly relative to said tubular member, and a second axial position, at which said collar axially overlies said dividing line and prevents rotation of said handgrip assembly relative to said tubular member; wherein: the base portion of said handle assembly and the axially adjacent portion of said tubular member have substantially the same external transverse cross section; said collar has an internal transverse cross section corresponding to the external transverse cross sections of said base portion and the axially adjacent portion of said tubular member; the external transverse cross sections of said base portion and the axially adjacent portion of said tubular member and the internal transverse cross section of said collar are substantially elliptical; and the major dimensions of the elliptical transverse cross sections of the axially adjacent portion said of tubular member and said collar extend substantially perpendicular to the towing direction of the luggage. 2. The handle assembly of claim 1, wherein:said handgrip portion is eccentric relative to said axis of elongation so as to extend in part transversely beyond the transverse cross section of said tubular member; and by movement of said collar between said first and second axial positions, said handgrip assembly is selectively rotatable to and lockable in a plurality of rotational positions relative to said tubular member. 3. The handle assembly of claim 2, wherein said handgrip assembly has a generally P-shaped configuration, with said base portion forming the stem of the P-shaped configuration and the handgrip portion forming the loop portion of the P-shaped configuration.4. The handle assembly of claim 1, wherein:said handgrip portion is eccentric relative to said axis of elongation in the direction of the longer dimension of the elliptical transverse cross section of said base member; and by movement of said collar between said first and second axial positions, said handgrip assembly is selectively rotatable to and lockable in a first rotational position relative to said tubular member, at which said eccentric handgrip portion extends to one side of said tubular member in a direction substantially perpendicular to the towing direction, and a second rotational position relative to said tubular member, at which said eccentric tubular member is rotated 180° relative to said first rotational position and extends to the other side of said tubular member in a direction substantial perpendicular to the towing direction. 5. The handle assembly of claim 4, wherein said handgrip assembly has a generally P-shaped configuration, with the base portion forming the stem of the P-shaped configuration and the handgrip portion forming the loop portion of the P-shaped configuration.6. The handle assembly of claim 4, further comprising a pair of axially extending slots in the upper end of the axially adjacent portion of said tubular member, said slots extending through the upper end of said axially adjacent portion in the direction of the minor dimension of the transverse cross section thereof and being spaced apart in the direction of the major dimension of the transverse cross section thereof by a distance such that said collar, when rotated through 90° from said first or second rotational position and moved to said second axial position, is axially received within said slots to lock said handgrip assembly in a rotational position with said eccentric handgrip portion extending substantially in the towing direction.7. The handle assembly of claim 1, wherein said collar is comprised of zinc or a zinc alloy.8. The handle assembly of claim 1, further comprising a transition member mounted on the upper end of the axially adjacent portion of said tubular member, said collar when in said second axial position extending axially over at least a portion of said transition member.9. The handle assembly of claim 8, further comprising means for retaining said collar in frictional engagement with said transition member when said collar is in said second axial position.10. The handle assembly of claim 9, wherein said frictional retaining means comprises a locking taper formed on at least one of the internal surface of said collar or the external surface of said transition member.11. The handle assembly of claim 1, wherein said collar has a circumferential flange at the axially upper end thereof, said flange forming a finger grip for facilitating movement of said collar between said first and second axial positions.12. The handle assembly of claim 1, wherein:said tubular member comprises a telescopically extendable and retractable member; and said handgrip assembly further comprises a push button for operating a locking mechanism for control of the extension and retraction of said tubular member. 13. A handle assembly for towable, wheeled luggage, comprising:a tubular member having an axis of elongation and being adapted to be connected at one end to a piece of luggage; a handgrip assembly having a handgrip portion and a base portion, said assembly being mounted on the other end of said tubular member for rotation relative thereto about said axis of elongation, said rotation occurring along a dividing line between said handgrip base portion and the axially adjacent portion of said tubular member; a collar slidably mounted on said handgrip base portion in surrounding relation thereto for movement in the direction of said of axis of elongation between a first axial position, at which said collar is located on the handgrip assembly side of said dividing line and permits rotation of said handgrip assembly relative to said tubular member, and a second axial position, at which said collar axially overlies said dividing line and prevents rotation of said handgrip assembly relative to said tubular member; a transition member mounted on the upper end of the axially adjacent portion of said tubular member, said collar when in said second axial position extending axially over at least a portion of said transition member; and means for retaining said collar in frictional engagement with said transition member when said collar is in said second axial position; wherein said frictional retaining means comprises one or more raised portions on at least one of the internal surface of said collar or on the external surface of said transition member.
