Abstract
A cursor (151), designated to slide in a case formed by two thicknesses lying alongside the cursor, is formed by cuts parallel to the direction of sliding and by weak links designed to be broken by action on the cursor (151) in the direction of f1 which causes its initial sliding; cuts parallel to the direction of sliding form elongate slots (153) running alongside the cursor (151) and each terminating in a stop (151X) formed by the cursor and in a stop (121x) formed by the material of the intermediate thickness (121) from which the cursor is formed; the two stops (121X; 151X) interact to limit the sliding of the cursor with respect to the case.
Claims19
Device forming a slide rule and indicator, being made of laminar material, comprising a portion including tree layered thicknesses of which two outer ones of said thicknesses form a case and an intermediate one of said thicknesses forms a cursor designed to slide in the case, characterized in that
- the cursor is formed in said intermediate thickness by cuts parallel to the direction of sliding of the cursor and by weak links designed to be broken by action on the cursor which causes its initial sliding,
- and that said cuts parallel to the direction of sliding of the cursor form an elongate slot running alongside the cursor and terminating in a cursor stop formed by the cursor and a frame stop formed by the material of the intermediate thickness from which the cursor is formed, the two stops interacting to limit the sliding of the cursor with respect to the case.
A prismatic box made of laminar material, the box comprising:
- a plurality of walls;
- one of said plurality of walls of said box is formed by a ruler having a portion including three layered thicknesses two of which form an outer surface and an inner surface of said wall and together form a case for a cursor and an intermediate one of said thicknesses forms said cursor designed to slide in said case;
- the cursor is formed in said intermediate thickness by cuts parallel to the direction of sliding of the cursor and by weak links designed to be broken by action on the cursor which causes its initial sliding;
- and
- said cuts parallel to the direction of sliding of the cursor form at least one elongate slot running alongside the cursor and terminating in a stop formed by the cursor and a stop formed by the material of the intermediate thickness from which the cursor is formed, the two stops interacting to limit the sliding of the cursor with respect to the case.
A slide rule arrangement comprising:
- a first pane;
- a second pane arranged adjacent to said first pane, said first and second panes forming a case;
- a cursor pane arranged in sad case, said cursor pane including a cursor and a frame surrounding said cursor, said frame defining a frame open said cursor being arranged in said frame opening, said frame opening and said cursor having a shape to cause said cursor to be movable in said frame opening, said case and said shape of said frame opening and said cursor blocking removal of said cursor from said case, said cursor and said frame being connected by links which are breakable to cause said cursor to be slidable in said case.
