Abstract
Abstract A luggage cart of the type which unfolds from its storage into its luggage-carrying condition and vice versa, and in which the extending and collapsing handle is the principal space-saver, having the improvements of (1) a spring-biased detent to hold the handle in its extended position and a detent release to cause withdrawal of the detent preparatory to collapsing the handle, and (2) a novel plastic hinge to establish and support the luggage-carrying platform of the cart.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
241 words
An improved luggage cart of the type foldable from a compact storage condition into an open condition for transporting luggage at an airport or the like, said cart comprising a body having a back, a transversely oriented support member connected across said back, a spaced-apart pair of cylindrical members connected in vertical relation to said support member, a handle slidably disposed on said back for sliding movement in said cylindrical members between a compact storage position adjacent thereto and a position extending therefrom for facilitating the pushing and pulling of said cart, said handle being formed with two depending legs movable in said cylindrical members and having detent means thereon adapted to project through openings of a specified diameter in said cylindrical members for releasably holding said handle in said extending position on said cart back, and a cylindrical detent-release bar pivotally mounted on said cylindrical members having a diameter in cross section which is sized in relation to said diameter of each said opening of said detent means so that the pivotal traverse of said detent-release bar results in the projection thereof into said openings and establishes contact with said detent means such that the continuation of said pivotal traverse of said bar causes the complete withdrawal of said detent means from said openings and the release of said handle incident to allowing the sliding movement thereof from said extended position into said compact storage condition adjacent said cart back.

An improved luggage cart of the type foldable from a compact storage condition into an open condition for transporting luggage at an airport or the like, said cart comprising a body having a back, a transversely oriented support member connected across said back, a spaced-apart pair of cylindrical members connected in vertical relation to said support member, a handle slidably disposed on said back for sliding movement in said cylindrical members between a compact storage position adjacent thereto and a position extending therefrom for facilitating the pushing and pulling of said cart, said handle being formed with two depending legs movable in said cylindrical members and having detent means thereon adapted to project through openings of a specified diameter in said cylindrical members for releasably holding said handle in said extending position on said cart back, and a cylindrical detent-release bar pivotally mounted on said cylindrical members having a diameter in cross section which is sized in relation to said diameter of each said opening of said detent means so that the pivotal traverse of said detent-release bar results in the projection thereof into said openings and establishes contact with said detent means such that the continuation of said pivotal traverse of said bar causes the complete withdrawal of said detent means from said openings and the release of said handle incident to allowing the sliding movement thereof from said extended position into said compact storage condition adjacent said cart back.
Claim 3
Dependent Claim
71 words
An improved luggage cart as claimed in claim 1 wherein each said detent means is spring-biased to project from an internal position within one of said depending handle legs through an opening in said legs and is sized to further extend through said one of said cylindrical member openings, whereby said bar is adapted to press in against said protruding detent means preparatory to causing the sliding release of said handle.
