    摘要: Methods and apparatus for expanding a rod from a collapsed position to a formed position are disclosed. One such apparatus includes a plurality of segments for forming the body of the collapsible rod including with each segment coupled to each immediately adjacent segment of the plurality of segments. The apparatus may include a coupler for coupling each segment of the plurality of segments to each immediately adjacent segment of the plurality of segments. The coupler may stretch from a base segment to the tip of the apparatus and may be biased to apply a force to hold the plurality of segments in a formed position and to urge the plurality of segments into a formed position from a collapsed position. In the formed position, the plurality of segments may be aligned end-to-end to form a rod and in the collapsed position, the plurality of segments may be folded against each other such that cylindrical walls of each of the plurality of segments are positioned adjacent each other.

    摘要: A convertible bullet-proof backpack and vest includes a body section divided into a front portion, a middle portion, and back portion. The middle portion has a head slot opening, and the front and back portions have respective sections of bullet-proof fabric integrated therein. A zipper runs around an outer perimeter of the front and back portions. In a backpack configuration, the front portion and the back portion fold toward each other and the zipper secures the outer perimeters of the front portion and the back portion together thereby forming a hollow backpack interior between them. In a bullet-proof vest configuration, the zipper is unzipped thereby allowing a user to insert their head through the head slot opening such that the front portion hangs in front of a torso of the user and the back portion hangs behind the torso of the user.
