Abstract: A convertible, foldable stand and portable tray combination is designed to yield a maximum of utility. The stand is built of identical frames assembled in link relationship, the legs having slip-grip feet which are restrained in lateral spread by flexible reins. The stand features a removable footrest and removable braces. Portable trays, having invertible surfaces, handles, rails, and locks, feature open corners which act to facilitate many conversion arrangements on and off the stand. Tray conversions are described for obtaining vertical suspension, surface compartments, game boards, a collapsible tray system, aperture boards, side to side and edge to edge connections, bedroom lapboard, and, on the stand, many table combinations of level, slope, and level plus slope. One or more trays store between upper frame sections of the folded-up stand.

Abstract: For automotive use, an inexpensive gasoline tank theft guard adjustably attached so that owner may integrate the guard or not by choice of a quick manual setting. The guard utilizes a gasoline fill-tube cover, a lockable body-entry panel, and the owner's key and perhaps his license plate for intercepting access to the gasoline tank when cover and panel are proximate and closed, and for protection against gasoline theft when entry panel is locked. By way of example, a pin (10, FIGS. 3-6), pivotally anchored inside gasoline fill-tube cover (6) engages a receptacle (9) in the trunk lid (2) when the lid closes (FIG. 5). Owner's key (1) unlocks lid to free pin. Anchor heads (4, FIG. 3) are concealed behind mounted license plate (7, FIG. 4) and are designed to frustrate tampering. Stability and rattle of the adjustable pin are controlled manually (FIG. 7) and automatically (FIG. 8). Pin (10) pivots manually aside to disconnect the system.

Abstract: A deformable cradle, after reposit in, and beneath the looseleaf filler of, a ringbinder notebook, assists collection of the filler whenever the open ringbinder is closed. The cradle designs fit ringbinders employing two or more rings and accommodate ring widths from about one to three inches (25 to 75 mm). A binary guide is described; unitary cradles are shown and described; a cradle is shown and described as employing an independent centering means attached; methods and materials are shown and described for effecting dependent connections of a cradle to the spine of a ringbinder, both permanently and removably. Improvement resides in ability of a cradle to usher the filler out of the troughs under the ringbinder rings where filler stock is prone to catch and bind during ringbinder closure.

Abstract: In a collapsible tea table combination wherein a foldable X-legged stand provides level and lengthwise parallel crossbars, and supports the improved tray system, maximum usable planar spread of crossbars can be selectively spanned and detained by rails rigidly attached along two parallel sides of the tray-bed to provide a minimum usable tray elevation. Minimum usable planar spread of crossbars can be selectively spanned and detained by means of deformable hangbuttons inserted into apertures formed in the tray-bed near the rails to provide a maximum usable tray elevation. The tray can be rendered invertible by using reversible tray-bed material, by using rails which juts both above and below the tray-bed, and by using hangbuttons which are symmetrically contoured for vertical displacement and rotation. Inasmuch as hangbuttons rotate within their apertures, they serve as rotary locks for stabilizing a table erected from any one of the choice of practical tray settings.
