Patent number: 5921521Abstract: A short, crescent-shaped copy stand engages the bottom edges of sheets and holds the sheets upright. The stand includes a back and an integrally formed, relatively small front block. The back has a downwardly and forwardly sloping concave sheet backing wall, a substantially horizontal top wall and a stepped front wall. A ledge or step extends forward from the lower edge of the sheet backing wall. The ledge slopes downward and inward from the its outer edges. The backing is concavely curved about a slightly rearward sloping axis, and the ledge concavely curves or slopes slightly upward and outward along the backing wall. The block is integrally formed with the backing wall and ledge at the approximate center of the backing wall. The block has a curved, generally vertical rearward wall that extends upward from a center of the ledge. The backing and the rearward facing wall of the block define sides of a slot for receiving centers of sheet bottom edges.Type: GrantFiled: June 29, 1998Date of Patent: July 13, 1999Assignee: Microplas, Inc.Inventors: William T.

Patent number: 5632374Abstract: A holder for temporarily storing and displaying compact discs has a front, a back and a disc-receiving base sloping downward from the back to the front. The disc-receiving base has molded pockets or slots for receiving and vertically supporting the compact discs. Each pocket has a lead-in for quick drop-off of a disc and for guiding it to a trough at the bottom. The trough contacts the flat sides of the disc but does not touch the information containing regions on the programmed side. Three bumps extend inward from the walls of the trough for orienting the disc at a rearward leaning angle to enhance visual identification and to prevent the discs from tilting forward and becoming dislodged. Effective disc orientation is achieved by providing a straight slot, with no bumps, that is molded at the desired angle of disc tilt or inclination. The pockets have openings that are wider than the thicknesses of standard compact discs.Type: GrantFiled: December 7, 1995Date of Patent: May 27, 1997Assignee: Microplas, Inc.Inventors: Tyler Fitzsimmons, Steven E. Callahan, Todd K. Dyment, Jon Noce

Patent number: 5509731Abstract: A storage device stores computer data cartridges in individual boxes. The storage device can store multiple boxes of computer cartridges. Preferably six boxes are stored in one case. The case has two side walls, a back, an upper wall, and a lower wall. A case with multiple inner dividers forms inner chambers for holding and separating one box from another. An ejector is associated with each of the chambers. Each ejector has an elongated and tilted floor member extending from the front of the ejector to the back of the case. The upward tilted position of the floor member holds the boxes against the upper wall and back of the case and therefore does not allow unintentional ejection of the boxes. Pushing the ejector downward forces the tilted floor member downward, sliding and ejecting the box outward under its own weight. A comb-like clamp and ejector assembly has rear grippers that grip a downward edge of the back. Fulcrums upwardly tilt forward cantilevered fingers which form the floors of the chambers.Type: GrantFiled: October 18, 1993Date of Patent: April 23, 1996Assignee: Microplas, Inc.Inventors: Steven E.

Patent number: 5464091Abstract: Method and apparatus for protecting and storing media, such as magnetic storage discs. A protective cover is formed by a front side, a back side and a mechanism for engaging a storage container. The front side can be connected to the back side by a base that promotes the separation of the sides and their closure towards one another, or includes a recess conforming to the object to be protected, with at least one side having a detent for promoting the retention of the object, such as a rectangular jacket with a movable shutter for a magnetic storage disc. The recess can include a shutter lock. The protective cover is insertable into a storage tray which retains the protective cover by, for example, hingeable extensions of the tray which are folded against sides of the tray when the cover is to be inserted, and the cover is retained unless it is moved to a substantially vertical position which permits withdrawal.Type: GrantFiled: October 26, 1993Date of Patent: November 7, 1995Assignee: Microplas, Inc.Inventors: Steven E. Callahan, Robert G. Petit

Patent number: 5415298Abstract: A compact disc and data cartridge storage has a base, a back, a front and first and second opposite sides. A plurality of parallel ribs extend along a rear portion of the base and a lower portion of the back for separating stored data packages. The base has a rear portion and a front portion respectively sloped rearward and forward from a center line which extends between the sides. The front portion is longer than the rear portion. Ribs extend upward from the front and rear position to guide and separate the data packages. In one form, the ribs extend fully along the back portion and partially along the front portion for storing tall and thin objects between the ribs, leaning against the back portion with centers of gravity rearward of the central ridge before tipping selected thin objects forward and moving the center of gravity forward of the central ribs and allowing the thin objects to slide downward along the front portion of the base while held vertically between the ribs.Type: GrantFiled: November 30, 1993Date of Patent: May 16, 1995Assignee: Microplas, Inc.Inventors: Steven E.
