Definitions

  • deadbolt mechanism including single action double bolt release and more particularly, to such a construction which provides double latch or latch bolt protection which may be double keyed, yet is panic-free.
  • Two latch assemblies are positioned adjacent the first preferably having a latch spring urged extended and the second preferably having a deadbolt requiring deliberate movement to both extended and retracted, both preferably having outside keyed opearators with locks and inside hand operators.
  • an object of this invention to provide a combined dual latch assembly including single action double latch or bolt release wherein there are two latch assemblies for door mounting which are preferably separately keyed requiring separate key outside operation, yet may be simultaneously operated by one of two inside operators.
  • the two latch assemblies being separately keyed and requiring separate key outside operation, the former single security of a single latch assembly is conveniently increased to double latch assembly security.
  • the provision of the double latch security is not at the sacrifice of two latch assemblies requiring separate inside operation for withdrawing the associated latches and permitting the door to be opened from the inside or interior of a structure, but rather, by unique integration of the two latch assemblies, operation of a single outside operator will quickly withdraw both latches or bolts and results in a panic-free" dual latch assembly.
  • the second latch assembly is of the pure deadbolt type which requires a deliberate extension of the bolt, once the door is closed, through a deliberate action.
  • interconnection for integration between the dual latch assemblies is provided by a relatively simple rack and gear assembly, the rack and gear assembly being arranged for transmitting relative motion between the dual latch assemblies in one direction but not in the other, and in this manner, transmitting motion from the one inside operator for dual latch retraction, while not transmitting motion from the other inside operator therebetween.
  • FIG. 2 is a horizontal sectional view, part in elevation, looking in the direction of the arrows 22 in FIG.
  • FIG. 4 is a vertical sectional view, primarily in elevation, looking in the direction of the arrows 44 in FIG.
  • the pinion drive plate 92 telescopes and engages flats 102 on the thumb bar inwardly extending portion 94 with an axially extending lug or pin 104 received in the side surface recess 98 of the pinion 90, a similar pin 106 projecting axially opposite of the pinion drive plate 92 again for alternate assembly as will be briefly hereinafter described.
  • the cam follower portion 124 of the cam follower plate 108 rides from the segmental flat cam surface 72 outwardly in one circumferential direction or the other onto the circumferential cam surfaces 73 of the cam plate, thereby pivoting the cam plate 64 and its connected drive plate 66 against the extended tensioning of the positioning spring 126.
  • a latch construction as defined in claim 1 in which said first outside operator is a keyed operator including a lock; in which said second latch assembly includes a second outside operator operable for actuating said second latch mechanism, said second outside operator being a keyed operator including a lock; and in which said gear and rack means is free of actuating said first latch mechanism during operation of said second outside operator.
  • a latch construction as defined in claim 1 in which said first inside operator is operable by rotation in either of opposite rotatable directions from a neutral position for actuating said first latch mechanism to withdraw said first latch; and in'which said gear and rack means includes said gear and said rack 'innerconnecting said certain of said first latch mechanism andsaid first inside operator and said certain of said second latch mechanism and said second inside operator for generally simultaneously actuating said first and second latch mechanisms upon operation of said first inside operator by rotation of said first inside operator in either of said rotational directions.
  • a latch construction as defined in claim l in which said gear and rack means includes said gear at said second latch mechanism and second inside operator, and said rack being a pivotal rack extending between said gear and said first latch mechanism and first inside operator, said rack being operably connected to said gear rotating said gear upon movement of said rack; in which cam means is operably associated with said first latch mechanism and said first inside operator normally positioning said rack stationary, said cam means being movable to move said rack and rotate said gear during actuation of said first latch mechanism by said first inside operator; and in which drive transmitting means is operably connected between said gear of said gear and rack means and said second latch mechanism for transmitting drive from said gear to said second latch mechanism for actuating said second latch mechanism and being free of transmitting drive from either of said second latch mechanism and second inside operator to said gear.
  • a latch construction as defined in claim 1 in which said first outside operator is a keyed operator including a lock; in which said second latch assembly includes a second outside operator operable for actuating said second latch mechanism, said second outside operator being a keyed operator including a lock; in which said gear and rack means is free of actuating said first latch mechanism during operation of said second outside operator, said gear and rack means including said gear at said second latch mechanism and second inside operator, and said rack being a pivotal rack extending between said gear and said first latch mechanism and first inside operator, said rack being operably connected to said gear rotating said gear upon movement of said rack; in which a cam is operably associated with said first latch mechanism and first inside operator operably engaged with said rack positioning said rack stationary, said cam rotating and pivoting said rack during actuation of said first latch mechanism by said first inside operator; in which resilient means is operably connected to said rack constantly urging said rack against said cam; and in which drive transmitting means is operably connected between said gear of said gear and rack means and said second latch mechanism for transmitting drive from said gear
