Abstract: A toggle tilt latch for a tiltable window assembly which comprises a base adapted to be mounted to a window sash, a handle pivotally mounted to the base and a plunger operatively associated and movable with the handle. The plunger has a free end which protrudes from the base and engages the window frame when the window sash is in its normal vertical position. The plunger is retracted into the base by rotating the handle away from the base. This will allow the window sash to tilt inwardly relative to the window frame. The handle portion not only gives a ready visual indication of whether the plunger is retracted or not but also can be used as hand holds by a user to facilitate tilting of the window sash relative to the window frame.

Abstract: A retaining catch for a tip-out sash provides an automatically deployed retainer mechanism for a sash slidably captive in a window frame or jamb. The sash can be raised and lowered by sliding it along the jamb. A releasable tenon, for example at the top edge of the sash, allows the user to rotate the sash out of the plane of the jamb, facilitating cleaning of the outside. Releasing the sash from the jamb by releasing the tenon activates a mechanism with a distal hook by which the edge of the sash remains captive and displacement of the edge of the sash from the jamb is limited to the unfolded length of the mechanism. The mechanism can be released fully from the jamb by manual action of the user, whereupon the hook returns under spring bias to reside along the edge of the sash.
