Abstract
A collapsible binocular and a blank for forming the same and made of semi-rigid sheet material, the binocular having front and rear lens mounting panels connected by top and bottom panels having integrally formed hinges therein, and end flaps attached to the lens mounting panels and connected at approximately the mid-point of the binocular, the top and bottom panels also including integrally formed hinges so that the binocular may be collapsed to a flat, compact package and stored within a one piece sleeve when not in use.
Claims16
A collapsible binocular having a housing formed of semi-rigid sheet material comprising:
- front and rear lens mounting panels,
- top and bottom panels, each being hingedly connected to both of said lens mounting panels, said top and bottom panels each having a pair of transverse fold lines substantially parallel to and spaced from said lens mounting panels,
- each of said lens mounting panels being provided with end flaps at each end thereof hingedly connected therewith, the end flaps of the rear lens mounting panel being hingedly connected to the end flaps of the front mounting panel for forming end walls of said binocular,
- whereby pressure application on said lens mounting panels urging said lens mounting panels toward each other causes outward deflection of said top and bottom panels and folding of said top and bottom panels along said transverse fold lines for collapsing said binocular and the collapsed binocular having a thickness approximately equal to the spacing of the lines of said pairs of fold lines.
A blank for a collapsible binocular formed of semi-rigid sheet material and comprising:
- an objective lens mounting panel of rectangular configuration and having a first top panel adjacent thereto and connected thereto at a first score lines,
- a glue flap connected top said first top panel opposite said objective lens mounting panel along a pair of second score lines,
- an ocular lens mounting panel,
- a bottom panel connecting said objective and ocular lens mounting panels along third and fourth score lines, said bottom panel including a pair of fold lines substantially parallel to and spaced from said third and fourth score lines,
- a second top panel including two score lines connected to said ocular lens mounting panel opposite said bottom panel along a fifth score line,
- each of said score lines being substantially parallel with, and each of said panels being of substantially the same length,
- an end flap attached to each end of each said lens mounting panels,
- whereby connection of said first and second top panels forms generally tubular collapsible binocular closed at the ends by said end flaps and having a collapsed thickness approximately equal to the spacing of the lines of said pairs of fold lines.
