Abstract: An automatic release buckle assembly including a mating buckle and latch tongue. A resiliently biased tongue latch engages the latch tongue to prevent withdrawal of the latch tongue from the buckle. A manually operable release mechanism is provided for causing the tongue latch to disengage the latch tongue to permit withdrawal of the latch tongue from the buckle. An automatic release device causes the tongue latch to disengage the latch tongue and includes an element movable between first and second positions where in the second position the tongue latch is disengaged from the latch tongue. A support is provided for supporting the movable element in the first position and a resilient element is provided for urging the movable element from the first position to the second position when the movable element becomes unsupported in the first position.

Abstract: A modular arrangement for supporting any one of a wide variety of sizes of reading and other materials at a freely selectable location in relation to any selected one of a wide variety of local environments, such as chairs, sofas, tables and the like is disclosed and includes an expansible reading material holding assembly along with a plurality of support mechanisms each accepted for attachment to a different class of local environment and an arrangement for coupling the holding assembly to a select one of the support mechanisms to provide limited manual adjustability of the elevation of the holding assembly relative to the selected support mechanism as well as a limited amount of manual adjustability of the holding assembly, from vertical to horizontal, as may be preferenced by the various users. In the horizontal attitude the holding assembly functions as a table.
