Abstract
Abstract A wheeled baggage hinge system (10) adapted for use on a luggage carrier (12). The luggage carrier (12) is adapted for wheeled rotation on a base surface (16) and is further structurally defined to allow opening of lid element (18) and bottom element (20) on a base surface (16) in a manner such that lid sidewall (30) and bottom sidewall (34) lie in interfacing contact with the horizontal base surface (16) when luggage carrier (12) is opened. The wheeled baggage hinge system (10) includes a hinge mechanism (44) composed of a pair of bottom planar elements (52) and (54) rotatively coupled to a central planar element (56) which is pivotally mounted to each of bottom planar elements (52) and (54). The central planar element (56) includes an extended transverse length to allow non-interference of wheel elements (38) and (40) when lid element (18) and bottom element (20) are opened for interfacing contact with a base surface (16).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
A wheeled baggage hinge system for coupling a luggage bag lid element and a bottom element in rotative displacement, said lid and bottom elements each having a respective sidewall and bottom wall comprising: (a) at least a pair of wheel elements secured respectively to a lower surface of said bottom walls of said lid and bottom elements, said wheel elements being substantially aligned each with respect to the other in a transverse direction; and, (b) luggage hinge means secured to said bottom walls of said luggage lid and bottom elements for rotative displacement therebetween, said lid element and said bottom element being transversely displaced each from the other by a distance sufficient to provide non-interference of said wheel elements when said lid and bottom sidewall elements are positionally located in contact interface with a substantially horizontal base surface, said wheel elements being secured to said luggage hinge means.
Claim 2
Dependent Claim
148 words
A wheeled baggage hinge system for coupling a luggage bag lid element and a bottom element in rotative displacement, said lid and bottom elements each having a respective sidewall and bottom wall comprising: (a) at least a pair of wheel elements secured respectively to a lower surface of said bottom walls of said lid and bottom elements, said wheel elements being substantially aligned each with respect to the other in a transverse direction; and, (b) luggage hinge means secured to said bottom walls of said luggage lid and bottom elements for rotative displacement therebetween, said lid element and said bottom element being transversely displaced each from the other by a distance sufficient to provide non-interference of said wheel elements when said lid and bottom sidewall elements are positionally located in contact interface with a substantially horizontal base surface, said wheel elements being secured to said luggage hinge means.
Claim 3
Dependent Claim
65 words
The wheeled luggage hinge system as recited in claim 1 where said luggage hinge means includes: (a) a pair of bottom wall planar elements secured to said bottom walls of said luggage bag bottom elements; and, (b) a central planar element extending in said transverse direction, said central planar element being pivotally coupled to said pair of bottom wall planar elements on opposing ends thereof.
Claim 4
Dependent Claim
35 words
The wheeled luggage hinge system as recited in claim 2 where said lid element and said bottom element are pivoted each with respect to the other about an axis line substantially normal said transverse direction.
Claim 5
Dependent Claim
40 words
The wheeled luggage hinge system as recited in claim 3 where said luggage hinge means includes a pivot pin element extending through rotatively cooperating and aligned sleeve elements formed on said bottom wall planar elements and said central planar element.
Claim 6
Dependent Claim
41 words
The wheeled luggage hinge system as recited in claim 2 where said wheel elements are rotatively coupled to each of said bottom wall planar elements, each of said wheel elements extending from said bottom wall planar elements by a predetermined distance.
Claim 7
Dependent Claim
37 words
The wheeled luggage hinge system as recited in claim 5 where said central planar element extends in said transverse direction by an amount substantially equal to the sum of said predetermined distance extensions of said wheel elements.
Claim 8
Dependent Claim
36 words
The wheeled luggage hinge system as recited in claim 5 where said central planar element extends in said transverse direction by an amount greater than the sum of said predetermined distance extensions of said wheel elements.
Claim 9
Dependent Claim
34 words
The wheeled luggage hinge system as recited in claim 1 where said wheel elements are rotatively coupled to a pair of flange elements, said flange elements being secured to said bottom wall planar elements.
Claim 10
Dependent Claim
23 words
The wheeled luggage hinge system as recited in claim 2 where said pair of bottom wall planar elements are of unequal transverse length.
Claim 11
Dependent Claim
61 words
The wheeled luggage hinge system as recited in claim 9 where said central planar element is rotatively coupled to said pair of bottom wall planar elements for providing an obtuse angle between said central planar element and one of said bottom wall planar elements when said bottom and sidewall elements are in said contact interference with said substantially horizontal base surface.
