Abstract
Latch hardware including drive rod fittings in which at least two profile grooves are undercut at an angle to one another within the frame shanks and drive rods are positioned, guided, and coupled to a corner guide. The profile grooves within the frame shanks are arranged stepwise and are of a depth which is larger than the thickness of the drive rods. In addition, the angled housing for the corner guide has at least one shank which is pushed on safety sleeves on molded edge stems in which may also be fixedly positioned parts which serve to guide the driving rod.
Claims7
Latch hardware for windows and door frames provided with frame members having grooves which are substantially cross-shaped in cross-section including lateral undercut portions and a base portion extending below the undercut portion, said latch hardware comprising:
- (a) at least two drive rods displacably guiding within the undercut portions, respectively of two adjacent frame members extending at an angle to one another to form a corner,
- (b) latch elements connected to each drive rod,
- (c) an L-shaped corner guide element positioned in the corner of said frame members, one leg of the guide element being disposed within the groove of the adjacent frame member and having a cross-section which substantially fills said groove, the other leg of the corner guide having a cross-section which fills the base of the groove of the adjacent frame member and has a longitudinal slot on the side facing the adjacent frame member,
- (d) a pair of connecting elements connected, respectively, to said two drive rods, one of the connecting elements being slidable within said longitudinal slot and the other connecting element being guidingly mounted with respect to said one leg of the guide element,
- (e) a flexible re-directing member extending within the corner guide element for connecting the pair of connecting elements, and
- (f) clamping means located in the grooves of the frame members outside of the movement area of the drive rods for clamping the corner guide element in the corner position within the frame.
