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.
