US 6,220,411 B1 · Expandable luggage

Abstract

An item of expandable luggage includes a substantially rigid main peripheral frame and a substantially rigid secondary peripheral frame. A peripherally continuous gusset of flexible material is connected between the two peripheral frames. Opposite wall panels of the main peripheral frame are joined to corresponding opposite wall panels of the secondary peripheral frame by bridge assemblies, one such assembly being associated with each of the opposite wall panels of the respective frames. Each bridge assembly includes a pair of parallel spaced-apart slide rails affixed to the wall panel of the main peripheral frame, a substantially rigid bridge plate affixed to the wall panel of the secondary peripheral frame and slidably received by the slide rails, and a releasable latch that couples the bridge plate to the wall panel of the main peripheral frame in at least one position in which the secondary peripheral frame is held securely in a position spaced apart from the main peripheral frame.

Dependent claims

An item of expandable luggage comprising

a frame having a first substantially rigid component and a second substantially rigid component, each of which includes a pair of opposite rectangular peripheral wall panels that together with another pair of peripheral wall members form the peripheral boundary of a variable volume enclosure and a generally rectangular area,
a peripherally continuous gusset of flexible material connected between the perimeter wall panels and peripheral wall members of the two frame components, and
a bridge assembly joining each wall panel of the first component to a corresponding wall panel of the second component in coplanar relation and for linear displacement of the two components toward and away from each other, each bridge assembly including
a pair of parallel spaced-apart slide rails affixed to the wall panel of the first component,
a substantially rigid bridge plate affixed to the wall panel of the second component and slidably received by the slide rails, and
a latch releasably latching the bridge plate to the wall panel of the first component in at least one position in which the second component is held spaced apart from the first component.

An item of expandable luggage comprising

a frame having a substantially rigid main frame component that includes a pair of opposite rectangular planar main wall panels forming together with a pair of wall members the peripheral boundary of a larger main volume and a rectangular area and a substantially rigid secondary frame component that includes a pair of opposite rectangular planar secondary wall panels forming together with a pair of wall members the peripheral boundary of a smaller secondary volume and a rectangular area that is the same in size and shape as that formed by the wall panels and wall members of the main frame component;
a peripherally continuous gusset of flexible material connected between the wall panels and wall members of the main frame component and the wall panels sand wall members of the secondary frame component;
and
a bridge assembly joining each wall panel of the main frame component to a corresponding wall panel of the secondary frame component in coplanar relation and for linear displacement of the secondary frame component toward and away from the main frame component, each bridge assembly including
a pair of parallel spaced-apart slide rails affixed to the wall panel of the main frame component,
a substantially rigid bridge plate affixed to the wall panel of the secondary frame component and slidably received by the slide rails, and
a latch releasably latching the bridge plate to the wall panel of the main frame component in at least one position in which the secondary frame component is spaced apart from the main frame component such that the luggage item has a total volume substantially greater than the total of the main volume and the secondary volume.
