Abstract

A tubular lockset includes a push button locking actuator with an automatic kick-off feature. A spindle assembly extends between an interior knob or lever and an exterior knob or lever. A latch assembly includes a bolt and a locking member that is movable between a locking position, where the locking member engages the spindle assembly, and an unlocking position. When the latch bolt is moved about ⅛ inch, a locking member is disengaged from the spindle assembly to unlock the lockset. The disengagement occurs independently of any movement of the interior knob or lever.

Claims (43)

1. A tubular lock assembly having a tubular chassis comprising:

an exterior assembly;

an interior assembly having a push button locking mechanism;

a spindle assembly coupled to the exterior assembly and the interior assembly and including an actuator;

a latch assembly coupled to the spindle assembly including a locking member movable between a locking position and an unlocking position, a biasing member detent configured to bias the locking member in the locking position, an actuator, a bolt configured to engage the locking member and move the locking member from the locking position to the unlocking position, the locking member being movable to the unlocking position, independent of movement of the bolt, in response to movement of the interior assembly, the locking member being movable to the unlocking position, independent of movement of the bolt, in response to movement of the actuator,

wherein the spindle assembly includes a full round spindle, the locking member including means for engaging the full round spindle to prevent movement of the exterior assembly.

2. A tubular lock assembly having a tubular chassis comprising:

an exterior assembly;

an interior assembly having a push button locking mechanism;

a spindle assembly coupled to the exterior assembly and the interior assembly and including an actuator;

a latch assembly coupled to the spindle assembly including a locking member movable between a locking position and an unlocking position, a biasing member detent configured to bias the locking member in the locking position, an actuator, a bolt configured to engage the locking member and move the locking member from the locking position to the unlocking position, the locking member being movable to the unlocking position, independent of movement of the bolt, in response to movement of the interior assembly, the locking member being movable to the unlocking position, independent of movement of the bolt, in response to movement of the actuator,

wherein the interior assembly includes a half round configured to engage the locking member and move the locking member to the unlocking position.

3. A tubular lock assembly having a tubular chassis comprising:

an exterior assembly mounted on an outside surface of a door;

an interior assembly mounted on an inside surface of the door and having a rotating handle and a push button locking mechanism;

a spindle assembly coupled to the exterior assembly and the interior assembly; and

a latch assembly coupled to the spindle assembly including locking means for moving between a locking position and an unlocking position, resilient means for retaining the locking means in the locking position, and first means for moving the locking means from the locking position to the unlocking position, independent of movement of either the interior assembly or the exterior assembly;

second means, coupled to the exterior assembly, for moving the locking means from the locking position to the unlocking position, independent of movement of either the interior assembly or the first means for moving; and

third means, coupled to the interior assembly, for moving the locking means from the locking position to the unlocking position in response to rotation of the interior assembly, independent of movement of either the exterior assembly or the bolt means for moving.

4. A tubular lock assembly having a tubular chassis comprising:

an exterior assembly mounted on an outside surface of a door;

an interior assembly mounted on an inside surface of the door and having a push button locking mechanism;

a spindle assembly coupled to the exterior assembly and the interior assembly; and

a latch assembly coupled to the spindle assembly including locking means for moving between a locking position and an unlocking position, resilient means for retaining the locking means in the locking position, and first means for moving the locking means from the locking position to the unlocking position, independent of movement of either the interior assembly or the exterior assembly;

second means, coupled to the exterior assembly, for moving the locking means from the locking position to the unlocking position, independent of movement of either the interior assembly or the first means for moving; and

third means, coupled to the interior assembly, for moving the locking means from the locking position to the unlocking position in response to movement of the interior assembly, independent of movement of either the exterior assembly or the bolt means for moving,

wherein the spindle assembly includes a spindle having a slot and the locking means includes a locking member having a tongue configured to engage the slot to lock the tubular lock assembly and the first means for moving includes a bolt disposed in the latch assembly to engage the locking member to move the tongue out of the slot.

5. The assembly of claim 4 wherein the second means for moving includes an actuator disposed in the slot and configured to cam the locking member out of the slot.

6. The assembly of claim 4 wherein the third means for moving includes a half round coupled to the interior assembly, the half round being disposed to engage the locking member to move the tongue out of the slot in response to movement of the interior assembly.

7. A tubular lock assembly having a tubular chassis comprising:

an interior assembly having an interior operator and a push button locking mechanism;

an exterior assembly having an exterior operator;

a spindle assembly coupled to the exterior assembly and having a spindle and a locking slide, the spindle having means for moving the locking slide and a longitudinally extending slot, the spindle rotating in response to movement of the push button locking mechanism between a spindle locking position and a spindle unlocking position, the locking slide being moveable from an unlocking position to a locking position in response to rotation of the spindle from the spindle unlocking position to the spindle locking position; and

a bolt assembly coupled to the spindle assembly and including a bolt and a locking member, the locking member being configured to engage the slot to prevent rotation of the spindle from the spindle locking position to the spindle unlocking position, the bolt being movable between a latching position and an unlatching position in response to movement of one of the interior operator and the exterior operator.

8. The assembly of claim 7 further including first means coupled to the exterior operator for moving the locking member out of engagement with the slot.

9. The assembly of claim 7 further including second means coupled to the interior operator for moving the locking member out of engagement with the slot.

10. The assembly of claim 7 further including third means coupled to the bolt for moving the locking member from the locking position to the unlocking position.

11. A tubular lock assembly having a locked condition and an unlocked condition, the assembly comprising:

an interior assembly;

an exterior assembly;

a spindle assembly coupled to the interior assembly and the exterior assembly and having a spindle, a locking slide and a locking bar, the locking slide being moveable between a first position in the unlocked condition and a second position in the locked condition and the locking bar being moveable between a first position in the unlocked condition to a second position in the locked condition;

a push button locking mechanism coupled to the spindle, the push button locking mechanism being moveable between a first position in the unlocked condition and a second position in the locked condition, the spindle moving to the second position in response to movement of the push button lock mechanism to the second position, the locking slide moving to the second position in response to movement of the spindle to the second position, and the locking bar moving to the second position in response to movement of the spindle to the second position; and

a bolt coupled to the locking bar, the locking bar moving from the second position to the first position in response to movement of the bolt.
