In one embodiment, a frame assembly includes a base frame member, two peripheral frame members and two connecting members connecting the two peripheral frame members to the base frame member.

An item of expandable luggage includes a substantially rigid main peripheral frame and a substantially rigid secondary peripheral frame.

Further, the peripheral frame defines an opening.

A second perimeter frame may join the second panel and the third panel, with the second perimeter frame defining a second cavity in between the second panel and the third panel.

A first perimeter frame may join the first panel and the second panel, with the first perimeter frame defining a first cavity in between the first panel and the second panel.

The support structure comprises a peripheral frame (2, 4) and an anchor-region (6, 7) located substantially lower than the peripheral frame (2, 4) when the arrangement is in use.

A case- body outer peripheral frame (9) and a cover outer peripheral frame (10) of the case body (4a) and the cover (4b), respectively, are formed by injection molding.

Cooperating with the peripheral frame is a laminated panel which is structurally mounted to and sealingly spans the peripheral frame opening to form a structural and leak proof interconnection.

The holding frame (14) is detachably fitted to the outer peripheral frame (12) from the underside.

The perimeter frame (14) comprises a first frame component (26) which is detachably connected to a second frame component (28).

The peripheral frame (13) is assembled and surrounded by the cover frames (131).

The high frequency vibration is generated at the peripheral frame about the screen.

The screening panel includes a peripheral frame and a plurality of ribs.

The first glass unit comprises a plurality of glass members (60, 64) and a second caming framework (58) supporting the glass members (60, 64).

The peripheral frame has an upper surface, a lower surface, and an outer peripheral surface interconnecting the upper surface and lower surface.
