Claims
- 1. In a door set having two subassemblies each having housing plates for permanent assembly in which such housing plates are located a predetermined distance apart and are fastened together using fasteners and with a cylinder lock in one subassembly comprising
- a) engagement means for temporarily engaging said subassemblies during installation prior to engagement with such fasteners, said engagement means in turn comprising
- i) a first projection on an assembly which projection has a stop means at its end;
- ii) a second projection on the other assembly which projection has a stop means at its end;
- said stop means being engageable to prevent separation until a predetermined light force separates them and such stop means being spaced apart prior to such separation a predetermined distance such that the housing plates are spaced the same as or greater than the distance apart during said temporary engagement than after final installation with such fasteners.
- 2. The door set of claim 1 in which the first projection is rigid and the second projection is flexible.
- 3. The door set of claim 1 in which the secured projection has an anchor portion which snap-fits into the other assembly.
- 4. The door set of claim 2 in which the rigid projection has a plurality of stops to provide varying separation distances of the plates while the first and second projections are engaged.
- 5. The door set of claim 1 in which one subassembly has a turn button located in a sleeve with the button having a configured recess for receiving a turn bar having a configured end which bar is part of the other subassembly and in which the door set has a turn button flexible projection positioned in a slot in such sleeve with such button projection in an orientation determined by said flexible button projection projecting into such slot whereby the projection orients the button to receive the turn bar into its recess as assembly of the subassemblies occurs.
- 6. The door set of claim 1 in which one subassembly has a turn button with a configured recess for receiving a configured turn bar end with the turn button adaptor positioned in a slot apertured sleeve with such button adaptor in a orientation determined by a flexible button projection projecting into such slot whereby the projection orients the button adaptor for assembly of subassemblies.
- 7. The door set of claim 5 in which the button projection flexes after assembly to permit door set operation thereafter.
- 8. The door set of claim 5 in which the button projection after assembly is sheared off to permit door set operation thereafter.
- 9. In a door set having an outside subassembly including a stationary housing with a passageway therethrough and a ball-receiving cavity therein, a turn bar rotatable through a selected turning range; a cam connected to and rotatable with the bar, the improvement comprising
- a sleeve surrounding the cam and rotatable within the housing under a spring return force;
- a slot opening in the sleeve normally positionable due to such spring force opposite the ball-receiving cavity;
- a ball positioned in the slot opening and carried by the sleeve as it turns: and
- a cam pocket with a cam surface comprising part of the cam, said surface having a curved arcuate segment which surface when opposite said ball prevents such ball from moving out of ballreceiving cavity in the stationary housing
- whereby a selected rotation of the cam moves the ball through the slot into the housing cavity to lock the ball and rotation of the cam in the opposite direction through such arcuate segment is insufficient to allow the ball to commence moving out of the cavity.
- 10. The door set of claim 9 in which the curved segment arc is larger than the arc of rotation movement of the cam when caused to rotate to the full extent of its clearance and tolerance movement when locked and subjected to vibration.
