    Abstract: A window frame has one or more latches provided internally of a vent sill for pivotal engagement with a latch strike in the interior of a frame sill and a latch actuator extending outwardly through an opening in the inside face of the vent sill. A spring urges the latch into engagement with the strike with the latch and the actuator being movable in a linear horizontal direction so that a slot in the side of the actuator engages the edges of the opening through which the actuator extends to hold the actuator and the associated latch in a locked or non-pivotable condition. A second embodiment employs a similar pivotal and slidable latch member in a side frame of a horizontally movable vent frame which is pivoted into latching position inside an opening in a fixed vertical meeting rail and is retained in locked or non-pivotable condition by subsequent linear vertical movement of the latch to a restricted slot portion from which it cannot pivot from the locking position.

  • Patent number: 4103946
    Abstract: A bolt mechanism for a sliding door or the like has a body having a rectilinear slideway for slidably receiving a first member, which has a manually operable means for sliding the first member between a closing position and an open position. A second member is pivotally connected to the first member and has a bolt portion laterally offset from, but projecting generally parallel, to the path of the member in the slideway for engagement with a keeper or strike plate mounted on the door jam. The bolt mechanism has an adjusting means readily accessible from the edge of the door whereby the position of the bolt may be adjusted to accommodate minor variations in the relative positions of the bolt mechanism and the keeper from installation to installation.

  • Patent number: 3998481
    Abstract: A draw and pull latch consisting of a base plate for attachment to a cabinet, a body pivoted at one end on the base plate and normally covering the base plate, and a draw and pull nose pivoted on the body parallel to and spaced from the body-base plate pivot. The body carries a pivotal latching plate aligned with at least one latching hook on the base plate and urged by a torsion spring to a latching position. In the fully latched position the draw and pull nose pivot axis is above a plane through the body-base plate pivot axis and the keeper engagement by the draw and pull nose so that the latch will urge itself to a fully open position when the latch plate is disengaged from the latching hook.
