Fenestration unit with accessible IG space
Various systems and methods are provided for controlling access to the insulated glass space of a fenestration unit. A hinge lug is provided including a lug body having a mounting portion, a cam portion defining a curved cam surface, and a retention portion projecting from the cam portion, and a first retention arm extending from the lug body such that the retention arm is elastically deflectable away from the retention lip. A restrictor link is provided including a restrictor link body having a first end and a second end, wherein the restrictor link body is elastically deflectable, a securing lock positioned proximate the second end, and a cap extending from the securing lock, the cap defining an engaging surface operable to engage the lip channel of the sash. A latch system is provided including a latch base with a ramp access aperture and a latch body including a ramp.
1. A hinge lug comprising:
a lug body having, a mounting portion, the mounting portion defining a mounting surface,
a cam portion opposite the mounting portion, the cam portion defining a curved cam surface, and
a retention portion projecting from the cam portion, the retention portion including a retention lip; and
a first retention arm extending from the lug body such that the first retention arm is elastically deflectable away from the retention lip;
wherein the first retention arm includes a first trunk extending from the lug body and a first finger extending from the first trunk, the first trunk and the first finger extending at an acute angle relative to one another.
2. The hinge lug of claim 1 , further comprising a second retention arm opposite the first retention arm, the second retention arm being elastically deflectable away from the retention lip, the first retention arm including a first retention finger and the second retention arm including a second retention finger, the first and second retention fingers extending toward one another and being separated by a gap.
3. The hinge lug of claim 1 , wherein the first trunk has a decreased thickness at a location where the first finger extends from the first trunk relative to a thickness of the first trunk where the first trunk extends from the lug body.
4. The hinge lug of claim 1 , wherein the first retention finger is elastically deflectable between a first, retention position and a second, receiving position.
