Patent ID: 8726550

Claim:
Apparatus for holding and displaying an aeronautical chart or other type of map, said apparatus comprising, in combination: an elongated base member having spaced first and second base member ends, each of said first and second base member ends defining a hole; a double-ended, elongated first map support having a proximal end and a free distal end, the proximal end of said first map support positioned in the hole defined by said first base member end, said first map support extending away from said base member and the free distal end thereof spaced from said base member, and said first map support rotatable relative to said base member; first retainer structure for releasably retaining the proximal end of said first map support in the hole defined by said first base member end; a double-ended, elongated second map support member having a proximal end and a free distal end, the proximal end of said second map support positioned in the hole defined by the second base member end, said second map support extending away from said base member and the free distal end thereof spaced from said base member, and said second map support rotatable relative to said base member; second retainer structure for releasably retaining the proximal end of said second map support in the hole defined by said second base member end, said first and second support members being substantially parallel and independently manually rotatable; and brake structure for resisting manual rotation of said first and second map supports, said brake structure comprising flexible springs located at and connected to said first and second base member ends frictionally engageable with said first and second map supports to resist rotation of said first and second map supports, said flexible springs additionally comprising said first and second retainer structure for releasably retaining the proximal ends of said first and second map supports in the holes defined by said first and second base member ends, and said flexible springs comprising tension springs having flat surfaces bearing against outer peripheral surfaces of a said map supports.
