Abstract: A window latch mechanism for use on cab structures associated with agricultural and construction machinery having improved resistance against breakage. The resistance against breakage is accomplished by constructing the window latch from a resilient material shaped in a forked configuration having a first and second tine. The latches are oriented such that the tines maintain a general vertical orientation. The window latch is pivotally connected to one tine, and the remaining tine is supported by the window slide. Vertical forces imparted to the window are reflected onto the latch and cause the resilient latch tines to move relative to each other, thereby allowing the tines to absorb the forces.

The latch includes a stud adapted to be mounted in fixed position on one of the members and a receptacle adapted to be mounted in fixed position on the other of the members and located to engage with the stud when the members are brought together. A coupling on the stud and receptacle automatically couples and holds the two members together. A release on the stud and receptacle which is exposed for actuation acts to uncouple the latch and permit the members to be separated. The coupling includes at least one flanged finger on the stud resiliently displaceable and a fixed rim on the receptacle so that when the stud and receptacle are engaged the flanged finger will displace and engage the rim to close the latch. The release includes a surface to direct the resilient finger away from engagement with the rim and release the latch when the release is actuated.

Abstract: A guard grille for a window, door, or the like, has a retainer member which is fixedly attached thereto and which is adapted to releasably engage a latching mechanism which is retained on the wall adjacent to a window frame. The latching mechanism includes an inner latching member which is attached to a slidably mounted rod and an outer retainer collet which in the latched position retains the latching member within the retainer member. A spring is placed between the inner latching member and the retainer member, this spring being compressed when the mechanism is in the latched condition. The mechanism is unlatched by means of a knob located adjacent to the inner wall surrounding the window frame, this knob being attached to the rod connected to the inner latching member. Inward actuation of the knob moves the inner latching member away from the retainer collet against the spring, thereby releasing the latching mechanism, the spring and actuation by the operator driving the grille away from the window.
