Dental flosser

A flossing device (10) having a body (12) comprising a handle portion (26) and a barrel portion (28) terminating in a pair of spaced prongs (16, 18). A spool of floss (24) is mounted on the body (12), and is threaded about the body (12) in a plurality of grooves (70, 72, 74, 76) such that a length of floss (80) for flossing the teeth extends across the space between the prongs (16, 18). A trigger mechanism (20) operable by the same hand used to grasp the device (10) pinches the floss for tensioning the length (80) in one position and releases the floss for advancement to expose a new, clean length of floss (80) in a second position. The trigger mechanism (20) is moveable to a position wherein all soiled surfaces are fully exposed for cleaning.

Flossing device

A folding platform for a vehicle (12) comprising a first series of panels (2, 3, 4), and a second series of panels (5, 7, 9) which may be unfolded within the vehicle (12) to form load carrying shelves or a platform which may be used to support a mattress. The first series of panels (2, 3, 4), one of which is affixed to a shaft, rotate as a unit with the shaft. The panels fold to be stored against the rear of a folding seat back (11) in close parallel proximity to the seat back (11), thus occupying only a small volume and not interfering with the use of the rear cargo area or trunk (30) of the vehicle (12). The panels may be disposed in a flexible fabric container (101, 105) with seams between the panels serving as hinges.

Folding platform and shelves for use in vehicles

A rigid shell or framework (10) for a building structure, comprising a first pair of spaced supporting frames (11, 12) defining the end walls of the shell, a second pair of spaced supporting frames (13, 14) disposed at right angles to the first pair of frames and defining the side walls of the shell, and a plurality of further supporting frames (15) disposed intermediate the first pair of supporting frames, being supported by the second pair of frames, and in turn providing the structural support for the side walls, roof and floor defined by the rigid shell. The first pair of supporting frames comprises a pair of vertical load-bearing members (18, 19) integral with and secured to a pair of horizontal load-bearing elements (16, 17) at points spaced from the ends of such elements by from 1/8th to 1/4th their respective lengths. Vertical load-bearing members (22, 23) of the second pair of supporting frames (13, 14) also abut and are secured to the vertical load-bearing members (18, 19) of the first supporting frames (11, 12) along substantially their entire lengths to define four load-bearing columns (24) for the shell. Internal sheathing (37) and an external skin (38) provided on the plurality of further supporting frames (15) of the rigid shell define an annular cavity (43) extending about the periphery of the shell for solar heat collection and air circulation therethrough. The integral shell structure thus inherently defines an air circulation path extending about the side walls (39, 40), roof (41), and base (42) of the structure to facilitate efficient use of the structure for solar energy heat transmission.

Rigid shell for building structures

An attachment is provided for converting a vehicle, such as a compact car, into an expandable vehicle having an enlarged expandable usable volume, the attachment replaces a removed body portion of a standard type vehicle, such as the rear body panel of an automobile or a side body panel of a van, and is pivotally connected to the balance of the vehicle by an accordian folding hood to define an original enclosed usable volume in the collapsed position of the hood. The attachment comprises an extension shell whose volume is bisected by a diagonal extending through the pivot axis for the extension shell. The diagonal defines the confronting edges of the extension shell with the balance of the vehicle in the collapsed position of the hood. The extension shell in the collapsed position of the hood defines a half volume for the enclosed usable volume which when pivotally rotated about the pivot axis through an angle of 90.degree. describes an arch for the diagonal which defines a path of travel for the accordion hood to create a new expanded enclosed usable volume having an increased headroom and a total enclosed volume greater than twice that of the original enclosed volume. Many variations in this basic arrangement are described to provide a variety of configurations of cubical or rectangular volumes. The removed body portion, such as the standard rear window panel from a hatchback car, is reconnected to the extension shell to serve both its normal function in the collapsed position of the hood and as access to the expanded volume in the expanded position of the hood.

Attachment for converting a vehicle into an expandible vehicle

A body portion of a standard type vehicle, such as the rear body panel of an automobile or a side body panel of a van, is pivotally connected to the balance of the vehicle by an accordion folding hood to define an original enclosed usable volume in the collapsed position of the hood, which volume is bisected by a diagonal extending through the pivot axis for the movable body portion. The diagonal defines the confronting edges of the movable body portion with the balance of the vehicle in the collapsed position of the hood. The body portion in the collapsed position of the hood defines a half volume for the enclosed usable volume which when pivotally rotated about the pivot axis through an angle of 90 degrees describes an arch for the diagonal which defines a path of travel for the accordion hood to create a new expanded enclosed usable volume having an increased headroom and a total enclosed volume greater than twice that of the original enclosed volume. Many variations in this basic arrangement are described to provide a variety of configurations of cubical or rectangular volumes.
