Abstract
A slide latch assembly having a keyless toggle lock capability and capable of being unlocked by either a low level security key or a master key. When a user lifts up on the front grip piece or the rear grip piece of the latch assembly, a dual pawl rotary latch is opened so that the latch assemble can then be latched to a keeper. The lock cylinder can be provided with either a master annular ring on the front of the lock plug which can only be opened by a master key or a low level security annular ring which permits the lock cylinder to be opened by either the master key or the low level security key.
Claims9
A slide latch assembly for fastening a closure member to a keeper in a latched position, said slide latch assembly being capable of assuming a latched configuration in which said slide latch assembly engages the keeper, and said slide latch assembly being capable of assuming an unlatched configuration, said slide latch assembly comprising:
- a latching means for engaging the keeper when said slide latch assembly is in said latched configuration and when the closure member is in a closed position relative to the keeper, said latching means having a biasing means for biasing said latching means into engaging the keeper when said slide latch assembly is in said latched configuration and the closure member is in a closed position relative to the keeper,
- a locking module link for actuating said latching means, said locking module link being slidable relative to said latching means, said locking module link having a locking module link notch;
- a locking module adapted to be fixed relative to the closure member, said locking module having a toggle button, said toggle button having a toggle button protuberance, said toggle button being pivotable between a locked state in which said toggle button protuberance engages said locking module link notch thereby preventing sliding movement of said locking module link relative to said latching means and an unlocked state in which said toggle button protuberance does not engage said locking module link notch thereby permitting sliding of said locking module link relative to said latching means,
- said locking module further including a lock cylinder, said lock cylinder having a means for engaging said toggle button such that rotation of said lock cylinder pivots said toggle button between said locked state and said unlocked state;
- and
- a grip piece slidable relative to said latching means and connected to said locking module link such that upon sliding of said grip piece relative to said latching means said locking module link actuates said latching means,
- wherein said latching means comprises:
- a pawl actuator;
- a first rotary pawl, said first rotary pawl being rotatable between a latched position corresponding to said latched configuration of said slide latch assembly and an unlatched position corresponding to said unlatched configuration of said slide latch assembly;
- a second rotary pawl, said second rotary pawl being rotatable between a latched position corresponding to said latched configuration of said slide latch assembly and an unlatched position corresponding to said unlatched configuration of said slide latch assembly, said second rotary pawl having a lever, said first rotary pawl being rotated by said second rotary pawl upon actuation of said lever by said pawl actuator such that said first rotary pawl and said second rotary pawl rotate into their respective latched positions and engage the keeper;
- whereby sliding of said grip piece and said locking module link relative to said latching means actuates said pawl actuator and thus actuates said latching means.
A slide latch assembly for fastening a closure member to a keeper in a latched position, said slide latch assembly being capable of assuming a latched configuration in which said slide latch assembly engages the keeper, and said slide latch assembly being capable of assuming an unlatched configuration, said slide latch assembly comprising:
- a latching means for engaging the keeper when said slide latch assembly is in said latched configuration and when the closure member is in a closed position relative to the keeper, said latching means having a biasing means for biasing said latching means into engaging the keeper when said slide latch assembly is in said latched configuration and the closure member is in a closed position relative to the keeper,
- a locking module link for actuating said latching means, said locking module link being slidable relative to said latching means, said locking module link having a locking module link notch;
- a locking module adapted to be fixed relative to the closure member, said locking module having a toggle button, said toggle button having a toggle button protuberance, said toggle button being pivotable between a locked state in which said toggle button protuberance engages said locking module link notch thereby preventing sliding movement of said locking module link relative to said latching means and an unlocked state in which said toggle button protuberance does not engage said locking module link notch thereby permitting sliding of said locking module link relative to said latching means,
- said locking module further including a lock cylinder, said lock cylinder having a means for engaging said toggle button such that rotation of said lock cylinder pivots said toggle button between said locked state and said unlocked state;
- and
- a grip piece slidable relative to said latching means and connected to said locking module link such that upon sliding of said grip piece relative to said latching means said locking module link actuates said latching means.
