A book enclosure for the storage, transport and display of decorative pins. The book has page (s) that open for the viewing, securing, protecting and safe transportation of decorative pins in which the page surface is comprised of a puncturable and resilient material for the piercing through and repositioning of the post (s) portion of a decorative pin(s) and defining a mounting surface for decorative pins. Between the page (s) there is a protective page to prevent decorative pins from contact and potential damage. A translucent front with a zipper allows for the display and viewing of decorative pins. A zipper closure allows for the secure closure to protect pins from falling out. The book has a removable strap for shoulder or cross-body portage or to hang for display. The back of the book has a pouch enclosure for the storage of pin backs.

A screen structure comprises at least one support element comprising a bistable extendable member; a panel element attached to the at least one support element, wherein the at least one support element and the panel element are configured to be rollable about a first longitudinal axis, to provide for extension and retraction thereof along a direction generally perpendicular to the first longitudinal axis; a handle element for extending and retracting the at least one support element and the panel element upon application of a force to the handle element, wherein when the at least one support element and the panel element are substantially fully retracted, the handle element is arrangeable in one or more first positions and in a parked position; and at least one guide element comprising a curved or angled portion which the handle element is configured to bear against and move relative to, to guide the handle element from the one or more first positions to the parked position.

A device and method for temporarily establishing privacy at a scene, such as an accident site. An arm is removably mounted with respect to a base. A panel is movably mounted with respect to the arm to visually black the scene or accident site. A stand is removably mountable with respect to a surface, such as a ground surface. The panel is removably attachable to the stand. The panel can be moved between a closed position visually blocking the scene or accident site and an open position visually unblocking the scene or accident site.

Improvements in the straightness in the vertical plane of a screen panel attached within a rectangular frame structure employing split tubes as its top and bottom edges/struts are described. Areas permitting the straightness of the screen panel to be improved include zip attachment of the screen panel to the split tubes, dependence of teeth orientation, reinforcement of the frame structure using struts, clamping of the split tubes to the frame, and modification of the screen panel, individually or in any combination thereof.

A portable expandable device with a contracting mechanism which allows for many forms of recreational products and structures to be expanded, reinforced in the expanded shape, and then contracted easily to regain its portable form. The expansion means is exercised by the use of at least one of the following, resiliently extending, unfolding, inflating, as to become an expanding form which can then be easily retracted to the redeployed form. The retraction mechanism reverses the expansion process utilizing a mechanism which sequentially exerts the forces needed in the proper locations in order to ensure proper contraction. Disclosed embodiments utilized supplemental structural reinforcement of the expanded form through the use of joints, releasable interlocks, latching mechanisms, air bladders, to ensure the form is stable and usable. The objective being a stable structure with a rapid and easy deployment and a supplemental retraction means as to be easily transportable.
