Publication number: 20070284973Abstract: The Mobile Modular Furniture Framework consists units of furniture constructed to be moved without being unpacked. Each unit will have an internal mechanism to secure the items stored within. Possible securing mechanisms include, but are not limited to, air bags or internal straps. Each unit will also have a mechanism, a handle or a strap, that facilitates carrying. The units will be able to be stacked in combinations that produce visually attractive bookshelves, chests of drawers, dressers, filing cabinets, beds, wardrobes, or other furniture used for storage. There will be horizontal surfaces included in the framework that will combine with the storage units to create desks and tables. The Mobile Modular Furniture Framework includes a collection of bases, with and without wheels, upon which the storage units will sit to further enhance customizability and mobility. There will also be a collection of toppers help finish combinations, and, in some cases, add stability.Type: ApplicationFiled: June 5, 2006Publication date: December 13, 2007Inventor: Jannifer Jones

Publication number: 20070284975Abstract: An exemplary hanging file folder retainer is provided that, in one embodiment, includes a first attaching member, a second attaching member, and a retaining member. The first and second attaching members couple to a hanging file drawer rail in order to secure the hanging file folder retainer to the hanging file drawer rail. The second attaching member is linearly disposed from the first attaching member such that the hanging file folder retainer is secured to the hanging file drawer rail in at least two locations. The retaining member has a length sufficient to at least span the distance between said first and second attaching members and is functionally coupled to the first and second attaching member such that, in at least one functional position, the retaining member inhibits hanging file tabs from disengaging from the hanging file drawer rail.Type: ApplicationFiled: June 13, 2006Publication date: December 13, 2007Inventor: Donald B.

Publication number: 20070284976Abstract: A drawer slide structure comprises a slide base and a homing interlocking mechanism. The slide base is for holding passive and active movable devices. The active movable device is for shifting the passive movable device by outward movement of the drawer. The homing interlocking mechanism comprises a base, first and second pivotal rotating devices, and an elastic device. The homing interlocking mechanism is attached to the slide base to facilitate assembling production and damage repair. When the drawer shifts outward, the active movable device shifts the second and first pivotal rotating devices until being blocked by the retaining pillar and fixed by the pulling force of the elastic device. Besides, the lifting blocks on the first pivotal rotating device push the movable braking plates for achieving the purpose of interlocking. When the drawer shifts inward, the drawer slide shifts to its initial position automatically by the elastic device.Type: ApplicationFiled: June 8, 2006Publication date: December 13, 2007Inventor: Kuo-Sheng Huang
