A convertible wagon adaptable from an extending use position to a collapsed storage position. The wagon has a telescopically extensible center portion that slidably secures and separates oppositely disposed end enclosure portions. A telescopically extensible handle is provided for deployment when in use configuration allowing for directional mobility of the wagon by the user.

The present invention is a collapsible two-wheeled vehicle, wherein the vehicle comprises a down tube and a horizontal stay that are pivotably connected to one another at midsections thereof as well as being slidably connected to steering and seat assemblies, respectively. The slightly canted arrangement of the various members and assemblies provides a rigid structure to support an operator during use yet allows the vehicle to be collapsed to a compact size for storage and shipping. The vehicle ...

A catamaran type water craft having two tandem pairs of scissors-like folding mechanisms disposed between and pivotally connecting to the opposing upright surfaces of adjacent, juxtaposed hulls. The folding mechanisms comprise two pairs of overlapped cross-linked beams joined about central pivot joints. A pair of cross-linked overlapped forward bow beams can also be provided, arranged so as to rise at an increasing angle to the water craft as the water craft collapses. When the boat is collapsed...

A collapsible structure includes first and second longitudinally extending rigid members, and a connector pivotally connecting the first and second members for movement between a compact storage orientation, wherein the first and second members extend longitudinally in a substantially parallel relationship, and an erected use orientation, wherein the first and second members extend longitudinally in a substantially non-parallel relationship. Movement between the storage and use orientations requ...

The present invention a collapsible shelter comprises spaced apart first and second upright pleated wall sections disposed substantially parallel to each other, first and second slanted pleated roof sections joined at upper ends to form a saw tooth roof peak, and joined at lower ends to upper ends of said wall section to form saw tooth wall-roof junctions, wherein said pleated wall sections together with said pleated roof sections form a tunnel member which is collapsible by folding said pleated...

A collapsible bag comprising a flexible outer skin, defining an interior and a substantially unobstructed opening. Reinforcing material is provided around said opening to define a pocket containing a rigid support, which allows the bag to hydrostabilize when filled with a fluid.

A collapsible keyboard includes left and right subframes hinged to each other at proximate lateral sides by a hinge member. The hinge member includes a mounting member with front and rear mounting portions pivoted to the subframes, two wing members hinged to lateral edges of the mounting member, and couplers disposed to link the subframes and the wing members. As such, the subframes are turnable between deployed and collapsed positions, where the subframes are planar and face towards each other,...

A collapsible article is disclosed herein which comprises: a plurality of slats, each slat having opposing longitudinally extending edges, a flute extending along one edge, a bead extending along the other edge and adapted to fit within the flute of an adjacent slat, and at least one opening transversely extending between the bead and flute; and at least one elongated elastic member received in and extending through said at least one opening of each slat so that the slats are selectively positio...

A collapsible keyboard that is collapsible between a deployed configuration in which the keyboard is generally planar and a collapsed configuration, the keyboard being foldable about three substantially parallel axes between the deployed and collapsed configurations, the keyboard having four rigid subframes for supporting keys, each subframe being pivotally connected at a folding axis to an adjacent subframe. The keyboard preferably has support frames supporting keys thereon. The keys are slidab...

A collapsible structure has first and second wall panels, each wall panel having a foldable frame member having a folded and an unfolded orientation, a frame retaining sleeve for retaining the respective frame member, and a fabric material substantially covering each frame member to form the panel for each frame member when the frame member is in the unfolded orientation. The fabric assumes the unfolded orientation of its associated frame member. The foldable frame member for each wall panel fur...
