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.
Claims30
A tip-out window apparatus for a sash slidable in a jamb, comprising:
- at least two spaced protruding parts for mounting along an edge abutting the jamb at a slot in the jamb for receiving the protruding parts, whereby the sash is slidable in the jamb in a first, normal mode to open and close the window as the sash is maintained in a same plane with the jamb, one of the protruding parts being a releasable latch means, the sash being released and rendered rotatable around the other of the protruding parts and out of said plane when the latch means is retracted in a second, tip-out mode;
- and,
- a catch arm having a hook at a distal end of the catch arm, the hook being engageable in the jamb and being pivotably connected relative to the sash at a proximal end of the catch arm, the catch arm defining a maximum displacement between the jamb and the edge of the sash when the sash is released from the plane of the jamb in said tip-out mode, and the catch arm being fully releasable from the jamb by pivoting free the hook.
A tip-out window, comprising:
- a sash disposed in a jamb, the sash and the jamb having complementary structures whereby the sash in one mode is maintained in a plane of the jamb, and in a second mode is displaceable from the plane of the jamb;
- a latch means mounted on the sash for controllably fixing the sash in the jamb, the latch means including at least one extendible and retractable tenon for bridging between the sash and the jamb, the tenon when retracted releasing the sash from the jamb at least at one edge of the sash;
- and,
- a catch mechanism including a hook at a distal end of the catch mechanism, engageable in the jamb and being connected at a proximal end relative to the sash, the catch mechanism defining an at least temporary maximum displacement between the jamb and the edge of the sash when the sash is released from the plane of the jamb, the catch mechanism having a catch arm collapsible for stowing the catch mechanism along an edge of the sash, and being operable to engage the hook in the jamb when the latch means is operated, and manually releasable by pivoting the hook free of the jamb.
