Patent number: 5975296Abstract: A dental floss holder includes a pair of arms, each arm having a middle portion and first and second opposite end portions. The first end portion of each arm curves outwardly away from its respective middle portion wherein the middle portions of the arms are positioned proximate one another so as to define a pivot. The second end portions are movable between a first position in which the first end portions of the arms diverge away from one another, and a second position in which the first end portions are moved toward one another. Dental floss material has one end secured to the first end portion of one arm and an opposite end secured to the first end portion of the other arm. The dental floss material has a first tension when the first end portions are in their spaced apart position and a second tension when the first end portions are moved toward one another, said first tension being greater than the second tension. Further embodiments of the dental floss holder are also contemplated.Type: GrantFiled: October 27, 1997Date of Patent: November 2, 1999Assignee: Gore Enterprise Holdings, Inc.Inventors: John W.

Patent number: 5950386Abstract: A wall construction for subdividing building space includes a pair of interconnected frames forming a rectangular arrangement, the interconnected frames having abutting vertical side edges and non-abutting vertical side edges, and a removable cover for covering a portion of the interconnected frames, the cover including cover vertical side edges, the cover being removably supported on the interconnected frames. In one form, the cover spans the abutting vertical side edges of the interconnected frames with at least one of the cover vertical side edges being located between the non-abutting vertical side edges. In another form, the cover vertical side edges are both located between the non-abutting vertical side edges of the interconnected frames, and further both are misaligned with the abutting vertical side edges.Type: GrantFiled: May 1, 1998Date of Patent: September 14, 1999Assignee: Steelcase Inc.Inventors: David A. Shipman, Robert J. Luchetti, Gregg R. Draudt, Charles A. Seiber, Phillip M. Hobson, Benjamin G. Shaw, James B. Eldon, III, David D. McClanahan

Patent number: 5899036Abstract: A freestanding portable partition assembly and related system are provided for open office spaces and the like. Each partition system includes a floor channel having an aperture defined therein; a partition frame having a downwardly projecting leg assembly received in said aperture; and a locking plate slidably engaging the floor channel and having a slot receiving a portion of the downwardly projecting leg assembly therein for releasably coupling the partition frame to the floor channel. With this construction, the partition frames may be quickly and easily connected to the floor channels, and the entire assembly may be shipped with the floor channel attached without fear of damage. Moreover, the resulting assembly resists damage from catastrophic events, such as earthquakes.Type: GrantFiled: November 26, 1996Date of Patent: May 4, 1999Assignee: Steelcase Inc.Inventors: Charles A.

Patent number: 5746035Abstract: A freestanding portable partition panel and related system are provided for open office spaces and the like. Each panel includes a skeleton-like frame having two vertical uprights positioned adjacent opposite side edges thereof. A foot extends downwardly from the bottom of the frame to abuttingly support the panel freestanding on a floor surface. Two pairs of horizontal stringers are attached to the outer faces of the uprights in a vertically spaced apart relationship to rigidly interconnect the same, and define therebetween two horizontal raceway cavities which open to the opposite side faces of the frame, and extend continuously between the opposite side edges thereof. Hence, when like panels are interconnected side-by-side, the open ends of adjacent raceway cavities are aligned and communicate.Type: GrantFiled: December 26, 1995Date of Patent: May 5, 1998Assignee: Steelcase Inc.Inventors: Charles A. Seiber, Benjamin G. Shaw, Christopher O. Lada, Phillip M. Hobson, Robert P. Poppe, David A. Shipman, Robert J. Luchetti, Gregg R. Draudt, James B. Eldon, III, David D. McClanahan

Patent number: 5607050Abstract: A floss dispenser has an essentially cylindrical case, the case including a cylindrical wall with an inner surface and two opposite ends. The case further includes an opening formed in at least one end for receiving a spool having floss wrapped around a hub. A cap is received within the opening in the end of the case. The cap has an annular wall for receiving and centering the hub of the spool when the cap is sealing the opening of the case, and at least one opening formed therein through which floss is threaded out of the end of the case. For securely attaching the cap to the case, a first interlocking engagement member associated with the cap engages a mating second interlocking engagement member associated with the case. The arrangement is such that upon insertion of the cap into the open end of the case and rotating the cap, the first engagement member of the cap engages the second engagement member of the case for preventing the axial movement of the cap relative to the case.Type: GrantFiled: November 1, 1995Date of Patent: March 4, 1997Assignee: W.
