Claims14
A fenestration system comprising:
- a door frame including a lock jamb;
- a strike assembly secured to the lock jamb;
- a sliding panel received in the door frame, the sliding panel including a lock stile;
- a lock assembly secured to the lock stile, the lock assembly being transitionable between a locked stated and an unlocked state, the lock assembly including:
- a housing;
- a cam gear pivotally secured to the housing and defining a receiving pocket and a cam surface;
- a reversal gear pivotally secured to the housing and engaging the cam gear;
- a lock cam pivotally secured to the housing and including a cam portion and a link portion and defining a cam surface;
- a first catch pivotally secured to the housing and configured to interact with the cam gear;
- a second catch pivotally secured to the housing and configured to interact with the lock cam;
- a link pivotally secured to the reversal gear and the lock cam, such that the reversal gear is prevented from being transitioned to the locked position when the first and second catches are in the open position by the cam surface of the cam gear engaging the first catch and the cam surface of the lock cam engaging the second catch;
- wherein the lock assembly is prevented from transitioning from the unlocked state to the locked state when the first and second door catches are in the first, open position.

A lock assembly configured to be secured to a lock stile, the lock assembly being transitionable between a locked stated and an unlocked state, the lock assembly including:
- a housing;
- a cam gear pivotally secured to the housing and defining a receiving pocket and a gear portion having a plurality of teeth, the cam gear defining a cam surface;
- a reversal gear pivotally secured to the housing and including a gear portion including a plurality of teeth positioned to engage with the gear portion of the cam gear;
- a lock cam pivotally secured to the housing and including a cam portion and a link portion and defining a cam surface;
- a first catch pivotally secured to the housing and configured to interact with the cam gear;
- a second catch pivotally secured to the housing and configured to interact with the lock cam;
- a link pivotally secured to the reversal gear and the lock cam, such that the reversal gear is prevented from being transitioned to the locked position when the first and second catches are in the open position by the cam surface of the cam gear engaging the first catch and the cam surface of the lock cam engaging the second catch;
- and
- a lock spring engaging the first and second catches to bias the first and second catches toward a first, open position,
- wherein the lock assembly is prevented from transitioning from the unlocked state to the locked state when the first and second door catches are in the first, open position.
