Abstract A folding poster board on which accounting forms are mounted, including a clamping means for clamping the forms to the board and a stripper plate for stripping forms from the board. A separate operating plate is provided for operating the stripper plate. The clamping member is mounted for rotation about a first axis, and the stripping plate and operating plate are mounted for rotation about a second axis parallel to and spaced from the first axis. Toggle spring means holds the clamping member resiliently in its open and closed positions. The operating plate for the stripper plate is resiliently biased away from the latter towards a relative position where further movement of the operating member will operate the stripper member. The board comprises first and second board members hinged together. When the second board member is folded over to cover the first board member, the clamping member, when moved to closed position, will engage the second board member and thereby prevent the poster board from inadvertently coming open.
A poster board comprising: board means including at least a first horizontal board member for supporting at least one accounting form, said accounting form being provided with a row of preformed mounting holes; mounting means on said board member for mounting said form thereto, said mounting means comprising a row of mounting pins rigidly secured to and fast with said board membeR, and adapted to extend through said holes in said form to hold said form on said board; means mounted on said board member and defining first and second axes of rotation extending in generally the same direction as said row of pins and horizontally spaced from each other, said second axis being between said first axis and said row of pins; clamping means for clamping said form to said board member, said clamping means being mounted for rotation about said first axis in one direction to an open, non-clamping position and in the opposite direction to a closed, clamping position; a stripper member rotatably mounted for operating movement about said second axis from a given position abutting the surface of said board member and underlying said form when the latter is mounted on said board member, to another position and effective to strip said overlying form from said pins in the course of said movement from said given position to said another position; a manually engageable and operable operating member for operating said stripper means independently of the movement of said clamping means when said clamping means is in its open position, said operating member being mounted for rotation about said second axis and being rotatable relative to said stripper member about said second axis; means operable, upon rotation of said operating member to a given position away from said stripper member, to cause further movement of said operating member in the same direction to cause operation of said stripper member, said last-mentioned means comprising cooperable interengageable portions of said stripper member and said operating member; spring means for resiliently urging said operating member to move to said given position relative to said stripper member; said clamping means when in its closed position holding said operating member downward toward said stripping member against the resilient urging of said spring means in the opposite direction; said clamping means when in closed position overlying and shielding said stripper and operating members.

A poster board comprising: board means including at least a first horizontal board member for supporting at least one accounting form, said accounting form being provided with a row of preformed mounting holes; mounting means on said board member for mounting said form thereto, said mounting means comprising a row of mounting pins rigidly secured to and fast with said board membeR, and adapted to extend through said holes in said form to hold said form on said board; means mounted on said board member and defining first and second axes of rotation extending in generally the same direction as said row of pins and horizontally spaced from each other, said second axis being between said first axis and said row of pins; clamping means for clamping said form to said board member, said clamping means being mounted for rotation about said first axis in one direction to an open, non-clamping position and in the opposite direction to a closed, clamping position; a stripper member rotatably mounted for operating movement about said second axis from a given position abutting the surface of said board member and underlying said form when the latter is mounted on said board member, to another position and effective to strip said overlying form from said pins in the course of said movement from said given position to said another position; a manually engageable and operable operating member for operating said stripper means independently of the movement of said clamping means when said clamping means is in its open position, said operating member being mounted for rotation about said second axis and being rotatable relative to said stripper member about said second axis; means operable, upon rotation of said operating member to a given position away from said stripper member, to cause further movement of said operating member in the same direction to cause operation of said stripper member, said last-mentioned means comprising cooperable interengageable portions of said stripper member and said operating member; spring means for resiliently urging said operating member to move to said given position relative to said stripper member; said clamping means when in its closed position holding said operating member downward toward said stripping member against the resilient urging of said spring means in the opposite direction; said clamping means when in closed position overlying and shielding said stripper and operating members.

The combination according to claim 1, wherein: said clamping means includes means defining an external elongated finger-receiving recess, said recess including a lateral wall portion at least a portion of which comprises an oblique upwardly and laterally inwardly facing surface disposed on the opposite side of said first axis of rotation from the second axis of rotation, the arrangement being such that when said oblique surface is manually pushed against, there will be provided a force component directed to cause movement of said clamping means about said first axis from closed to open position.
