SECTION I - CLASS DEFINITION

This class includes all bolt elements and latching devices, not combined with lock structure, for securing in closed or adjusted position any closure element, such as a door, window, gate, trunk lid, box cover, bag frame, or the like.

SECTION II - REFERENCES TO OTHER CLASSES

SEE OR SEARCH CLASS:

49Movable or Removable Closures,   appropriate subclasses, particularly subclasses 276+ for closure fasteners when combined in or with closure operators, and this class (292) for devices for starting a closure open, or drawing it from a substantially closed to a fully closed position, wherein such operation is accomplished by cooperating surfaces on the latch bolts and keepers which function during movement of the bolts into or out of latching position relative to the keepers.
70Locks,   for key or combination locking devices.
99Foods and Beverages: Apparatus,   subclasses 349+ for fasteners combined with food compacting followers and subclass 402 for fasteners associated with hinged bread toaster grids.
109Safes, Bank Protection, or a Related Device,   subclasses 62+ for devices for safes and vaults commonly known as pressure mechanisms, the function of which is to cam the door tight in its jamb, and which usually serve to crack the door to an ajar position; and subclass 63.5 for devices for receptacles which render the closure fastener thereof ineffective when the receptacle is in a condition of abnormal use.
220Receptacles,   subclasses 315+ for receptacle closure fasteners.
