Abstract
Abstract A collapsible luggage carrying device is provided having a triangular telescoping back portion and a triangular luggage supporting base section connected thereto. Both the back and the base include elongated tubular frame members diverging from a common apex and being interconnected by a generally transverse connecting and stabilizing bar which maintains the triangular shaped back and base portion in a rigid, expanded position for carrying luggage. The base may also include a plurality of sections telescoped together to thus provide an adjustable length for accommodating several pieces of luggage. The apex of both the upright back portion and the base are interconnected with a flexible strap to provide an enclosed rigid triangular supporting frame surrounding the articles being transported.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
228 words
A portable luggage carrier comprising: wheel means; a frame including both a collapsible triangular upright back section adapted to extend upright, and, an attached triangular base platform portion adapted to extend horizontally and receive luggage for transport; handle means mounted atop said back section; hinge means providing for pivotal movement of the back section into a position adjacent to the base portion; said upright back section including a pair of collapsible leg sections; pivotal means joining said leg sections and said leg sections constructed to diverge downwardly and outwardly of said pivotal means; said base portion including a pair of side members and joint means pivotally connecting said sides and said sides constructed to diverge outwardly of each other from said joint means; and, connecting means constructed for positioning and holding both the diverging leg sections of the upright back portion and the diverging side members of the base portion, wherein said luggage carrier is movable from a collapsed position to both a partially extended and fully extended position; said luggage carrier includes means mounting said wheel means and also includes movement compensating means operatively attached to said carrier to compensate for relative rotation between the leg sections of the upright back section and the side members of the base platform for the transport of luggage when said carrier is in the partially extended and fully extended position.
Claim 2
Dependent Claim
228 words
A portable luggage carrier comprising: wheel means; a frame including both a collapsible triangular upright back section adapted to extend upright, and, an attached triangular base platform portion adapted to extend horizontally and receive luggage for transport; handle means mounted atop said back section; hinge means providing for pivotal movement of the back section into a position adjacent to the base portion; said upright back section including a pair of collapsible leg sections; pivotal means joining said leg sections and said leg sections constructed to diverge downwardly and outwardly of said pivotal means; said base portion including a pair of side members and joint means pivotally connecting said sides and said sides constructed to diverge outwardly of each other from said joint means; and, connecting means constructed for positioning and holding both the diverging leg sections of the upright back portion and the diverging side members of the base portion, wherein said luggage carrier is movable from a collapsed position to both a partially extended and fully extended position; said luggage carrier includes means mounting said wheel means and also includes movement compensating means operatively attached to said carrier to compensate for relative rotation between the leg sections of the upright back section and the side members of the base platform for the transport of luggage when said carrier is in the partially extended and fully extended position.
Claim 3
Dependent Claim
54 words
The carrier of claim 1, wherein: said connecting means includes crossbar means extending between at least one pair of diverging members of the luggage carrier frame; said crossbar means also comprising a releasable locking member constructed to permit the diverging members to be moved from a diverging, operable position into a generally parallel position.
Claim 4
Dependent Claim
41 words
The carrier of claim 1, wherein: structural reinforcing and luggage restraining strap means are attached to the base portion and to the upright back section for structurally interconnecting said frame members to provide a luggage supporting triangle encircling the transported luggage.
Claim 5
Dependent Claim
22 words
The carrier of claim 1, wherein: said handle means include a movable handle portion which may be folded into a collapsed position.
Claim 6
Dependent Claim
118 words
The carrier of claim 1, wherein: said motion compensating means include connector means for attaching wheels to a portion of the base and having attaching means to permit relative rotation of the side members of the base portion within the attaching means as the luggage carrier is folded and unfolded; and, said crossbar means constructed for positioning and holding the diverging frame members comprises a releasable member extending between the wheels and having means operatively connected to each wheel in such a manner as to prevent rotation of the wheels as the luggage carrier is folded and unfolded, thereby allowing the luggage carrier to be used when the upright back section is in an intermediate, partially collapsed configuration.
Claim 7
Dependent Claim
109 words
The carrier of claim 1, and: said frame members of the upright back section having a plurality of telescoping tubular members and including a lower tubular section connected to said hinge means, an intermediate tubular member of smaller diameter than the lower tubular member and positioned to telescope into the lower tubular member, and, an upper tubular member of smaller diameter than the intermediate tubular member and positioned to telescope into the associated intermediate tubular member; and, each tubular member including at least one cooperating locking portion adapted to join with a locking portion of an associated tubular member when the tubular sections are extended from the collapsed position.
Claim 8
Dependent Claim
52 words
The carrier of claim 6, wherein: each side member of the lower base portion including a first tubular member pivotally attached to the associated hinge means and each side member also including a second tubular member of smaller diameter than the first tubular member and attached to telescope into first tubular member.
Claim 9
Dependent Claim
128 words
The carrier of claim 6, wherein: said lower tubular section of the upright back portion and the first tubular member of the lower base portion having substantially the same length and diameter and thereby being interchangeable to reduce the number of parts required for the luggage carrier; and, said upright back portion and said lower base portion being collapsible by telescoping from a fully extended, operable position into a shortened position and thereafter said crossbar connecting member being collapsible to thereby bring the leg sections of the upright back and sides of the base portion into a collapsible position, and further, said base portion being rotatable into a position adjacent collapsed leg members of the upright portion to thereby completely collapse the luggage carrier for easy, portable transport.
