Definitions

  • This invention relates generally to door hardware and more particularly to door locks capable of either-handed installation and having concealed screws on both inside and outside lock portions.
  • US-A-4 037 865 discloses a device for mounting door handles on the door
  • US-A-3 955 387 describes a heavy duty cylindrical lock set adaptable for various functions.
  • a door lock comprising two interchangeable handle assemblies, one being an inside handle assembly and the other being an outside handle assembly, each handle assembly including a threaded bore therein, there being an outside chassis having means for engaging the outside handle assembly and means for engaging a bolt drawbar cam, and there being an inside chassis having means for engaging the inside handle assembly and comprising an externally threaded stud for threaded attachment with the inside handle assembly threaded bore and means for engaging a bolt drawbar cam.
  • a door lock is known from US-A-3 955 387.
  • the invention is characterised by the features of the characterising portion of claim 1.
  • handle assembly knob assembly and lever assembly, when used, are interchangeable. They are used in their generic form to refer only to the portion of a door lock which is grasped with the hand to operate the latch mechanism.
  • the drawing shows an exploded partially sectional elevation view of a door lock mounting device.
  • the lock, or latch bolt assembly is not illustrated but it may be any of a commonly available array of such latch bolt mechanisms.
  • the lock includes two identical handle assemblies 10 consisting of knobs 15 which are rotatably captured in respective bushings 20.
  • the method of capture, an "E" ring or other commonly used retaining device is not illustrated.
  • Each bushing 20 is internally threaded and is itself rotatably captured in a trim ring 100 by a retaining ring, a formed flare or other means used for such rotatable retention applications.
  • Each trim ring 100 is equipped with two or more internally threaded hollow posts projecting into a door cavity.
  • Each bushing 20 has provisions, not illustrated, for application of torque to thread the bushings 20 onto studs 170 of an inside chassis 150, as appropriate.
  • the handle assemblies 10 are functionally identical and, so long as the knobs 15 are symmetrical, are interchangeable completely. In the case of levers or other asymmetric handles, actual interchangeability may be limited, although functional interchangeability still applies.
  • the handles 10 are equipped with bores 18, or spindle sockets, having longitudinal teeth, corners or grooves for engaging mating longitudinal features of spindles.
  • An outer chassis 50 and the inner chassis 150 have several features in common and several slightly different features.
  • the body of the chassis 50 has two or more holes to accommodate internally threaded posts 30 of the handle assemblies 10.
  • the sleeve 70 projects outwardly from the chassis body and supports an outer spindle 85 which has longitudinal features designed to mesh with the spindle bores 18 of the handle assemblies 10.
  • the outer spindle 85 has an externally cylindrical portion having a bore 82 in which the inner spindle 80 is captured in a driven arrangement.
  • the inner spindle 80 and bore 82 have longitudinal meshing features which constrain the inner spindle 80 and outer spindle 85 to turn together.
  • Biasing means 83 are also included within the bore 82 of the outer spindle 85 to force the inner spindle 80 to an extended position.
  • the inner spindle 80 is captured within the bore 82 by staking or other common means which is not illustrated. Both spindles 80 and 180 are for engaging a bolt drawbar cam (not shown).
  • the inside chassis 150 is substantially identical to the outside chassis 50 with a few important exceptions.
  • Mounting legs 130 are spaced to mate with the internally threaded posts 30 of the knob assemblies 10. When inserted in the door cavity and aligned with the outside chassis 50, the mounting legs 130 register with the internally threaded posts 30 such that the posts 30 fit smoothly within alignment bores 165 in the mounting legs 130.
  • Mounting screws 160 are inserted from the inside surface of the inside chassis 150 through the mounting legs 130 into engagement with the threads of the posts 30, and when securely tightened, hold the inside chassis 150, outside chassis 50 and knob assembly 10 in securely fixed relationship with each other.
  • the posts 30 extend through holes in the outside chassis 50 into the alignment bores 165 in a telescopic arrangement which permits adjustment for doors of varying thicknesses.
  • the mounting legs 130 also have recesses 168 behind the heads of the mounting screws 160. These recesses accommodate the posts 30 of the knob assembly 10 when the knob assembly is mounted on the inside of the door.
  • Spindles 180 and 185 have the same relationship by means of spindle bore 182 and spindle bias 83 as has been described for the spindle couple of the outside chassis 50.
  • the stud 170 supports the spindle 185 in its bore while the external threads provide connection capability with the bushing 20 of the adjacent handle assembly 10. This connection capability is a key feature in that it permits attachment of either of the functionally identical handle assemblies 10 to the inside chassis 150 and, by simply reversing the positions of the inside chassis 150 and outside chassis 50, the handing of the door can be changed or accommodated.
  • the sleeve 70 of the outside chassis 50 has no external threads and therefore will not engage the internal threads of the bushing 20.
  • the outside handle assembly 10 presents no access to either the mounting screws 160 or to the mounting stud 170.
  • the internally threaded posts 30 of the inside handle assembly 10 telescope smoothly into the recesses 168 of the mounting legs 130 when the handle assembly is finally attached to the inside chassis 150 by means of the stud 170.
  • the door lock is pictured with two mounting posts and two mounting legs but may, of course, be provided with three or more legs. Size, weight and strength requirements of the installation will ultimately determine the number of mounting legs required.
