A lock mechanisms for a fenestration assembly, such as a sliding door, includes a strike element preferably coupled with the door frame and a catch assembly preferably coupled with the fenestration member slidably supported within the frame. The catch assembly includes a catch having structure defining an element receiving slot. The catch is mounted for shifting among a plurality of positions including an engaged position in which the element is received within the slot and retained therein by the catch when the fenestration member is in a closed position, a disengaged position in which the element is disengaged by the catch when the fenestration member is shifted out of the closed position, and an intermediate position in which the element is received within the slot and the catch is positioned between the engaged and disengaged positions. The catch assembly further includes locking structure for shifting the catch from the intermediate position to the engaged position, and thereby shifting the fenestration member to the closed position, and for locking the catch in the engaged position. The lock mechanism may also be provided with structure for blocking movement of the strike element out of the element receiving slot defined in the catch, when the catch is in the engaged position so as to reduce the risk of intrusion through the fenestration assembly.

[ The inventor hereby states his intent to rely on the doctrine of equivalents to determine and assess the reasonably fair scope of the present invention as pertains to any apparatus not materially departing from but outside the literal scope of the invention as set forth in the following claims:] [1.]1. A lock mechanism for a fenestration product having a frame member and a fenestration member shiftably supported by the frame member for movement into and out of a closed position, said lock mechanism comprising:a strike element; anda catch assembly,said catch assembly and said strike clement being mountable to respective ones of the members so that there is relative shifting movement between said catch assembly and said strike element when the fenestration member is shifted into and out of the closed position,said catch assembly includingscatch having structure defining an element receiving slot,a mounting assembly configured to shiftably mount said catch for shifting among a plurality of positions including an engaged position in which said element is received within said slot and retained therein by said catch, a disengaged position in which said element is disengaged by said catch, and an intermediate position in which said element is received within said slot and said catch is positioned between said engaged and disengaged positions, anda locking assembly operable to shift said catch from said intermediate position to said engaged position, and thereby cause said relative shifting movement in a direction corresponding to shifting of the fenestration member to the closed position, and lock said catch in said engaged position such that said locking assembly prevents said catch from shifting out of said engaged position,said locking assembly including a locking component shiftably supported for selective movement between a locked position in which the locking component engages and thereby prevents the catch from shifting away from the engaged position and an unlocked position in which the locking component is disengaged from the catch and thereby permits the catch to shift freely toward and away from the engaged position,said catch being yieldably biased into the disengaged position.
