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.
Claims54
A window tilt latch, comprising:
- base means for mounting said tilt latch on a window sash mounted in a window frame;
- handle means pivotally mounted to said base means;
- and
- plunger operatively associated with said handle means, said tilt latch being adapted so that said window sash is not tiltable relative to said window frame in which said window sash is mounted when said plunger is in a first position and said window sash is tiltable relative to said window frame when said plunger is in a second position, whereby ready visual observation of the position of said handle means will indicate whether said plunger is in said first or second position and whereby said handle means can be sued as hand holes by a user to facilitate tilting said window sash with respect to said window frame.
