A foldable paper sheet is formed having a sheet body portion, a sheet lower side flap extending out from a lower side edge of the sheet body portion, a pocket panel extending out from a bottom edge of the sheet body portion, and a pocket side flap extending out from a side edge of the pocket panel. The pocket side flap is folded in towards the pocket panel, the pocket panel is folded up and the pocket side flap is glued to the back face of the sheet body portion. The sheet lower side flap is folded and glued to the pocket panel. The pocket panel is thereby secured along both side edges to the sheet body portion, has an open top and thus defines a pocket on the back of the sheet body portion. The pocket panel can have a finger notch at the center of its top edge. A tab is cut out of the edge portion of the sheet body portion to form a tabbed divider sheet. The tab advantageously can be formed at any location along the edge portion including at a lower location directly adjacent to the pocket. Binder holes were punched in the paper preferably during an early production step of the foldable paper sheet. Binder holes in the pocket panel, the side edge flap and the sheet body portion are in alignment with the foldable paper sheet folded and glued. Two of the binder holes in the body portion are spaced above the pocket, and to reinforce these holes the sheet includes an upper side flap. This flap also has two binder holes which with the flap folded onto and glued to the back of the body portion align with the two body portion holes.

A device for illuminating a generally flat surface essentially without emitting significant light beyond the surface is particularly adapted for use as a book light. The device comprises a battery-operated light source contained within a housing to which a transparent light-conductive illuminating body is mounted in close adjacency to the light source to transmit the light through the illuminating body. The device may be placed with the illuminating body over a book or other flat surface for illuminated viewing through the transparent illuminating body. The illuminating body is tapered in a wedge shape to deflect the conducted light onto the underlying surface.

A binder for papers, photographs, or other sheet-like materials is provided with a cover having one or more window openings defined therein. A flat, transparent protective sheet is located in contact with the inside surface of the binder cover and a backing sheet overlies the protective sheet. The backing sheet is secured to the peripheral margin of the protective sheet, and elsewhere as required, to delineate at least one, and preferably a plurality of pockets. The pockets are formed between the backing sheet and the protective sheet. An elongated slit in defined through the backing sheet behind each pocket created. The peripheral edges of the backing sheet are permanently secured to the inside surface of the binder cover. Photographs or other flat display materials may be inserted into the pockets formed between the backing sheet and the protective sheet through the elongated slits. The pockets are delineated so that they are aligned with the window opening in the cover. The photographs or other display materials may thereby be viewed through the window openings from the outside through the transparent protective sheet. Selected display materials may be inserted and withdrawn from the pockets through the elongated slits in the backing cover.

This invention provides a padfolio, portfolio or other foldable business accessory that is organized with three hinged leaves (including two main leaves and one overriding leaf that folds over the main leaves when closed together) that may be unfolded and laid flat to expose various internal elements within an overall interior. The elements are organized so that a notepad is provided in a center leaf, while one of the opposing side leaves include a raised clock base having a well or recess for securing a clock having a folding stand that can be raised into an angled, standing position from a flat position. One main leaf also includes a support base that removably supports a personal digital assistant (PDA), that is normally secured flat against the leaf, but that can be hinged upwardly into at least one adjustable angled position whereby the PDA is tilted for easier viewing whilst working in another area of the padfolio, such as the notepad. In this manner, it is more accessible and easier to use. During folding of the leaves, both the clock and the PDA can be secured in a flat orientation for compact storage. The leaves can include, variously, a series of pockets and sleeves for carrying documents, effects and business accessories. In an illustrative embodiment, the a leftmost main leaf can include the pockets the PDA, the center leaf can include the notepad and the overriding leaf includes the clock.

There is an electric motor driven drop bolt having a housing which in use is mounted into a doorway frame and has the bolt pivotal therein by a mechanical drive set in a cage disposed at an operative position. The bolt is pivotal between a locking configuration where the bolt extends outward of the housing to engage in an aperture associated with a door within the frame and an unlocked configuration where the bolt is withdrawn to clear the aperture. The mechanical drive includes a screw shaft rotatable by the electric motor to move a roller nut along the length of the shaft whilst engaging a cam surface on the bolt. To obtain fail safe operation of the drop bolt the cage is slidable in the housing from the operative position to a disengaged position so that the bolt is movable from the locking configuration to the unlocked configuration without operation of the mechanical drive.
