A collapsible camping trailer or camper having a horizontal top panel which serves as the ceiling of the camper in the opened position and as a flat storage bed when the camper is in the collapsed position. A rigid front panel is pivotally affixed at its upper end to one edge of the top panel and has tracking members at its lower end received by a pair of channels in the camper floor. The rigid front panel collapses from a vertical position when the trailer is opened to a horizontal collapsed po...

A stereophone includes a headband which supports cup assemblies at each of its ends. The cup assemblies can be pivoted to a transport position in which they are enclosed within the headband. The ends of the headband may be fastened together to retain the cup assemblies in this position.

For taking up less space when not in use, a ski is designed with a folded joint between its ends. For locking the front and back parts of the ski in the in-line condition ready for use, it is possible to have a top part acting as a splint which is bolted, for example, to the inner ends of the two ski parts, possibly between two heel-pieces on top of the ski parts. As a further possible design, the system for locking the ski parts in the in-line position, two links with a toggle function may be u...

A collapsible carton comprising inner and outer snugly nestable tubular shells. Each shell includes a series of side wall panels hingedly connected together along their side edges. The shells are telescopically adjustable into and out of a set-up relationship in which the overlying side wall panels define a set of double-walled carton sides. A plurality of foldable strips interconnect adjacent bottom edges of the overlying side wall panels, the strips being unfolded and parallel to their respect...

A container able to be moved from a raised position to a folded position. The container has a base and a roof spaced. First members are pivotally attached to the base and extend upwardly when the container is raised. Second members are pivotally attached at one end to the roof and each pivotally attached at its other end to a first member. Upper side panels extend between the roof and a pair of second members. Lower side panels extend between the base and a pair of first members. Reciprocable lo...

A collapsible grill comprises a plurality of rods which are attached at their ends to a pair of flexible cables. A pair of bars are attached by several turns to the respective ends of the first rod and constrained to prevent escape from near the ends by a pair of pins in the first rod near its ends. The bars have hooks which engage detents on the last rod, which may be formed of indentations or the like, so that when assembled for use, the bars are held by the spring action of the last bar and t...

An elongated horizontal base is pivotally connected at one end with an upstanding link and has a stop forming tongue struck out of its link connected end portion in contact with the link. The link is connected at its upper end portion with a horizontally disposed U-shaped yoke for engagement with and removing a boot. The yoke and link may be pivoted to a common plane and pivoted as a unit to underlie the base when not in use.

A collapsible container comprising collapsible stepped walls which are formed by alternating substantially horizontal surfaces and substantially vertical surfaces.

A paperboard tray and a blank therefor is disclosed which is collapsible to form a carton. More specifically, the subject tray may be collapsed and sealed to hold a product and may then be subsequently opened and reformed into a tray for use in serving or cooking. A pair of handle flanges are provided defining carrying handles when the tray is opened and for structurally rigidifying the tray and preventing its inadvertent collapse.

A bulkhead formed of nesting channels connected together with toggle arms. The channels are attached to the forward wall of a refrigerated trailer and form a barrier to protect a refrigeration unit and provide an unrestricted air passage duct for return air. A channel shaped outboard extending support member swivels on toggle arms and due to its overcenter arrangement, remains extended vertically. When the outboard member is rotated upwardly, the channels and toggles nest together decreasing the...
