the first joining member forms at least one beam extending from the first zipper teeth, and the second joining member forms at least one beam extending from the second zipper teeth; or the first joining member forms one beam at each of the opposing ends, and the second joining member forms one beam at each of the opposing ends.
5 . The luggage case of claim 4 , further comprising:
a first end clip for securing the at least one first beam and the at least one second beam, the end clip including a first end portion for receiving the at least one first beam and the at least one second beam; and
a second portion extending from the first portion and defining an interlocking feature.
6 . The luggage case of claim 5 , wherein the interlocking feature includes a first feature and a second feature symmetrically positioned about a long axis of the second end portion, and/or the first feature is a protrusion, and the second feature is an aperture.
7 . The luggage case of claim 1 , wherein:
the first joining member includes at least one end clip engaging the first zipper teeth and/or the second zipper teeth.
8 . The luggage case of claim 1 , further comprising:
a modular expansion zipper assembly comprising:
a first and second zip tape members, each including a tape defining zipper teeth extending along opposing outer and inner edges;
a flexible gusset attached between the first and second zip tape members;
an expansion zip formed by releasably engaging the zipper teeth on the inner edges, the expansion zip converting between a unexpanded position when the zipper teeth are engaged, and an expanded position when the zipper teeth are disengaged; and
a first outer zipper edge defined by the zipper teeth on the outer edge of the first zip tape member;
a second outer zipper edge defined by the zipper teeth on the outer edge of the second zip tape member; and
the first outer zipper edge releasably engaging the first zip member; and
the second outer zipper edge releasably engaging the second zip member.
9 . The luggage case of claim 8 , wherein:
the joining member may include a middle portion positioned along the opposing ends of the first and second zip tape members, and at least one protrusion extending away from the middle portion;
the at least one protrusion forming an end clip on one of the first outer zipper edge, second outer zip edge, or the expansion zip.
10 . The luggage case of claim 8 , wherein:
the joining member is positioned at least partially on a lower surface of the gusset.
11 . The luggage case of claim 8 , wherein:
the joining member includes a first rail formed on the first zip tape member and a second rail formed on the second zip tape member, each rail extending from the middle portion at an angle towards the outer edge of the first and second zip tape member, respectively, when the expansion zip is in the expanded position.
12 . The luggage case of claim 8 , wherein:
the middle portion extends when in the expanded position, and the middle portion folds when in the stowed position.
13 . The luggage case as defined by claim 12 , further comprising:
a second end clip for securing the beams at the opposing ends of the first and second zipper teeth respectively, the second clip having a first portion for receiving the beams, and a second end portion defining a second interlocking feature; and
wherein the interlocking feature of the first end clip engages the second interlocking feature of the second end clip to secure the two end clips together.
14 . The luggage case of claim 13 , wherein:
the second interlocking feature includes a first feature and a second feature; and
the first feature on the first end clip engages the second feature on the second end clip, and the second feature on the first end clip engages the first feature on the second end clip to secure the two end clips together.
