An apparatus for carrying sound production components is disclosed, comprising a rigid frame including vertically interspaced first, second, and third surfaces. Each of the first surface, second surface, and third surface releasably engage with a plurality of sound production components. A first wing and a second wing are pivotally mounted to the third surface to releasably engage with at least one of the plurality of sound production components. A bag receives the rigid frame in a folded configuration and encloses the rigid frame and the plurality of sound production components.

Child carriers, backpacks, bags, and alterable frames assemblies that resist buckling or breaking when an excessive force is applied. Frame members may move until engagement member engage when expanding the frame assembly. A fabric body may allow for movement of frame members, limit such movement, and support & strengthen the frame members within sleeves. The frame members include U-shaped and inverted U-shaped frame members engaging at engagement member when the frame is uncollapsed.

A horizontally movable bowling bag is provided to prevent movement of a bowling ball configured such that, in order to prevent movement or falling of the bowling ball when a frame is horizontally moved or when a cover is opened, four or more points of the bowling ball including a lower part of the bowling ball and a bottom surface of the bowling ball along an outer circumference thereof are adjacent to or supported by an upper part of a ball cup provided at the frame and an inner surface of the frame, whereby movement of the bowling ball in the frame is prevented when the frame is horizontally moved.

An expandable container is disclosed. The expandable container may include a frame with extendable sections, an expandable material covering the frame and protective plates secured to the expandable material.

a luggage with composite material integrally formed frame includes a first shell, a second shell, a first frame, and a second frame. The second shell is openably assembled to the first shell. The first frame is integrated with the first shell and is located on the outer edge of the first shell. The second frame is integrally formed with the second shell and located on an outer edge of the second shell. When the first shell and the second shell are closed, the protruding engagement member of the second frame is engaged in the recessed engagement groove of the first frame.

The present disclosure is directed to a frame assembly. The frame assembly includes, for example, a bottom support structure, a handle housing coupled to the bottom support structure, a holder coupled to the handle housing, and a diagonal support structure diagonally positioned and coupled to the handle housing via the holder. The handle housing, the holder, and the diagonal support structure together form an integrated structure.
