Abstract
A latch assembly for use in a flip panel sign display is disclosed. The latch assembly includes a latch pin releasably coupled to the sign panel in a manner to prevent relative rotation therebetween. A latch is disposed an end of the latch pin. The latch pin includes a neck portion and an end portion, the neck portion having a particular cross-sectional configuration which prevents relative rotation in the side panel. The latch is rotatably supported on the end portion and capable of rotation between a locked position which retains the flip panels in a desired configuration and an unlocked position which permits relative positioning of the flip panels.
Claims21
A latch assembly for releasably retaining a display on a sign panel comprising:
- a pin including a neck portion which is adapted to be inserted into an aperture formed in the sign panel and having a cross-section for preventing rotation of said pin and a first axle extending from a first end of said neck portion and having a first retaining flange formed on an end thereof;
- a first latch having a bore formed therethrough to receive said first axle such that said first latch is rotatably supported on said first axle between said neck portion and said first retaining flange, said bore having a shoulder formed therein which engages said retaining flange for releasably securing said latch to said pin, said bore opposite said shoulder formed in said first latch having an enlarged diameter to provide clearance for said neck portion of said pin such that said latch rotates on said axle;
- and
- wherein said lever further comprises a detent formed on an interior surface defined by said enlarged diameter for releasably retaining said lever in a first location relative to said latch pin.

A latch assembly for releasably retaining a display on a sign panel comprising:
- a pin including a neck portion which is adapted to be inserted into an aperture formed in the sign panel and having a square cross-section for preventing rotation of said pin, a first axle extending from a first end of said neck portion and having a first retaining flange with a tapered leading face formed on an end thereof, and a second axle extending from a second end of said neck portion and having a second retaining flange with a tapered leading face formed on an end thereof;
- a first latch including a hub portion having a bore and a shoulder formed therein and a lever extending from said hub portion, said bore receiving said first axle and said first retaining flange engaging said shoulder such that said first latch is rotatably supported on said first axle between said neck portion and said first retaining flange;
- and
- a second latch including a hub portion having a bore and a shoulder formed therein and a lever extending from said hub portion, said bore receiving said second axle and said second retaining flange engaging said shoulder such that said second latch is rotatably supported on said second axle between said neck portion and said second retaining flange.
1 more element
A sign display comprising:
- a sign panel having an aperture formed therein;
- a movable display panel;
- a latch assembly disposed adjacent said movable display panel for releasably retaining said movable display panel on said sign panel, said latch assembly including a pin having a neck portion which is adapted to be inserted into an aperture formed in said sign panel such that said pin is prevented from rotating relative to said sign panel and a first axle extending from a first end of said neck portion and having a first retaining flange formed on an end thereof;
- a first latch having a bore formed therethrough to receive said first axle such that first latch is rotatably supported on said first axle between said neck portion and said first retaining flange, said first latch being positionable between an unlocked position and a locked position, said bore formed in said first latch having a shoulder formed therein which engages said first retaining flange for releasably securing said first latch to said pin, a portion of said bore opposite said shoulder formed in said first latch having an enlarged diameter to provide clearance for said neck portion of said pin such that said latch rotates on said axle;
- and
- wherein said lever further comprises a detent formed on an interior surface defined by said enlarged diameter for releasably retaining said lever in a first location relative to said latch pin.
3 more elements
A sign display comprising:
- a sign panel having an aperture formed therein;
- a movable display panel;
- a latch assembly disposed adjacent said movable display panel for releasably retaining said movable display panel on said sign panel, said latch assembly including a pin having a neck portion which is adapted to be inserted into an aperture formed in said sign panel such that said pin is prevented from rotating relative to said sign panel and a first axle extending from a first end of said neck portion and having a first retaining flange formed on an end thereof;
- a first latch having a bore formed therethrough to receive said first axle such that first latch is rotatably supported on said first axle between said neck portion and said first retaining flange, said first latch being positionable between an unlocked position and a locked position;
- a second axle extending from an end of said neck and having a second retaining flange formed thereon;
- and
- a second latch having a bore formed thereon to receive said second axle such that said second latch is rotatably supported on said second axle between said neck portion and second retaining flange.
