Abstract
A sign stand is provided having a foldable support mechanism for quickly and conveniently manipulating the sign panel from a deployed state to a folded state. The fold-up sign panel assembly includes a foldable support mechanism having a hinge assembly coupling the upper and lower vertical brace members. The horizontal brace members are pivotally secured to the hinge assembly. A latch mechanism is operable for releasably retaining the foldable support mechanism in the deployed state.
Claims31
A fold-up sign panel assembly positionable between a folded position and a deployed position, said fold-up sign panel assembly comprising:
- a hinge assembly having a fist hinge member and a second hinge member interconnected by a hinge pin for rotation about a first axis;
- a first brace member rigidly secured to said first hinge member;
- a second brace member rigidly secured to a planar face of said second hinge member;
- third and fourth brace members pivotally connected to said second hinge member for rotation about second and third axes, respectively, said second and third axes being perpendicular to said first axis and perpendicular to said planar face of said second hinge member;
- wherein said second, third and fourth brace members are positioned parallel and adjacent to said first brace member in the folded position;
- and
- wherein said second brace member is positioned parallel to and extends from said first brace member and said third and fourth brace members are positioned perpendicular to and extend from said first brace member in the deployed position.
A fold-up sign panel assembly positionable between a folded position and a deployed position, said fold-up sign panel assembly comprising:
- a first brace member having a hinge plate on an end thereof;
- a second brace member having a hinged plate on an end thereof, said hinged plate being connected to said hinge plate for rotation about a hinge axis by a hinge pin;
- a third brace member connected to said hinged plate for rotation about a first pivot axis which is perpendicular to a longitudinal axis of said second brace member and perpendicular to said hinge axis;
- and
- a fourth brace member connected to said hinged plate for rotation about a second pivot axis which is perpendicular to a longitudinal axis of said second brace member and perpendicular to said hinge axis;
- a latch mechanism interposed between said first brace member and said second brace member, said latch mechanism being positionable between a locked position to prevent rotation of said hinged plate relative to said hinge plate and a released position to permit rotation of said hinged plate relative to said hinge plate, thereby enabling said fold-up sign panel assembly to be folded.
A fold-up sign panel assembly positionable between a folded position and a deployed position, said fold-up sign panel assembly comprising:
- a first brace member;
- a second brace member;
- a hinge assembly including a hinge plate secured to an end of said first brace member, a hinged plate secured to an end of said second brace member and a hinge pin connecting said hinged plate to said hinge plate for rotation about a hinge axis;
- a third brace member connected to said hinged plate by a first pivot pin for rotation about a first pivot axis, said first pivot axis being perpendicular to a plane defined by a longitudinal axis of said first brace member and said hinge axis;
- a fourth brace member connected to said hinged plate by a second pivot pin for rotation about a second pivot axis, said second pivot axis being parallel to said first pivot axis;
- a latch mechanism including a latch cover having a pair of side walls and an end wall defining a channel, a catch having a lost motion slot formed therein which receives an axle pin extending between said pair of side walls, and a spring interdisposed between said catch and said end wall said catch being slidably supported in said channel for movement between a locked position wherein said catch engages said hinged plate to prevent rotation thereof relative to said hinge plate and a released position wherein said catch releases said hinged plate to permit rotation thereof relative to said hinge plate;
- and
- a flexible sign panel secured to a free end of each of said first, second, third and fourth brace members.
A foldable support mechanism for a sign panel assembly having a plurality of supports including a first member, a second member, a third member and a fourth member, said foldable support mechanism being positionable in a deployed position wherein said second member is parallel to and extends from said first member and said third and fourth members are perpendicular to and extend from said first member, said foldable support mechanism further being positionable in a folded position wherein said second, third and fourth members are positioned parallel and adjacent to said first member, the improvement comprising a hinge assembly wherein said first member is interconnected to said second member at a hinge for rotation about a first axis, said third member interconnected to said second member at a first pivot for rotation about a second axis, and said fourth member interconnected to said second member at a second pivot for rotation about a third axis, said second axis and said third axes being perpendicular to said first axis and perpendicular to a plane including at least one of said first and second members and at least one of said third and fourth members when the foldable support mechanism is in said deployed position.
