Abstract
A lockset mechanism having a semi-permanent mechanical connection between the interior and exterior components thereof is provided. The lockset mechanism includes an exterior cylinder assembly releasably coupled to a mounting plate, an interior cylinder assembly having a locking blade interdisposed between the mounting plate and the interior cylinder assembly for providing a semi-permanent mechanical connection. The locking blade is rotatably positionable from an unlocked position wherein the interior cylinder assembly is uncoupled from the mounting plate to a locked position wherein the interior cylinder assembly is coupled to the mounting plate upon rotation of a knob assembly.
Claims21
A lockset mechanism comprising:
- a first cylinder assembly having a first coupling member formed thereon and a first handle assembly operably associated therewith;
- a mounting plate interconnected to said first cylinder assembly by said first coupling member, said mounting plate having a second coupling member formed thereon;
- a second cylinder assembly having a second handle assembly operably associated therewith;
- and
- a locking member interposed between said mounting plate and said second cylinder assembly, said locking member being rotatably positionable between a locked position wherein said locking member engages said second coupling member to secure said second cylinder assembly to said mounting plate, and an unlocked position wherein said locking plate disengages said second coupling member to release said second cylinder assembly from said mounting plate.
A method of installing a lockset mechanism into a door, the door having a bore formed therethrough, the method comprising:
- positioning a first cylinder assembly such that a first coupling member extends through a bore of a door;
- securing a mounting plate to said first coupling member such that said mounting plate and said first cylinder assembly are secured to said door;
- positioning a second cylinder assembly over said mounting plate such that a second coupling member of said mounting plate is covered by said second cylinder assembly;
- and
- rotating a locking member interposed between said mounting plate and said second cylinder assembly to engage said second coupling member and secure said second cylinder assembly to said mounting plate.
A lockset mechanism comprising:
- a first cylinder assembly including a first handle and a shaft extending axially away from said first handle, said shaft having a blind bore formed in an end thereof opposite said first handle;
- a second cylinder assembly including a second handle, a sleeve extending toward said first cylinder assembly and a turnpiece having a turnpiece shaft extending into said sleeve;
- a turnpiece guide received within said sleeve and having an aperture formed therein, said turnpiece shaft being received within said aperture such that said turnpiece guide is slidably positionable along said turnpiece shaft from an engaged position to couple said turnpiece shaft with respect to said sleeve for co-rotation and a disengaged position to uncouple said turnpiece shaft with respect to said sleeve from co-rotation;
- wherein said turnpiece guide aligns said turnpiece shaft with respect to said blind bore.
