Abstract
An apparatus is disclosed for engaging locking elements to secure and lock a window sash to a window frame. A force transmitting device may be included with a guide forming a channel for an elongated tape transmits a horizontal movement provided by an operator mechanism into a vertical movement at a locking mechanism. The operator mechanism may include a removable bezel and a removable handle to facilitate access to the operator mechanism. A lockbar retainer of a compact construction guides a lockbar that actuates the locking elements.
Claims31
An apparatus for locking a window having a frame and a sash movable relative to the frame, which comprises:
- a first receiver for attachment to the sash and a second receiver for attachment to the sash, the first receiver having a retaining profile;
- a lockbar for attachment to the frame and selectively movable between a locked position and an unlocked position;
- a first strike mounted to the lockbar and a second strike mounted to the lockbar;
- at least one lockbar retainer having a base for attachment to the frame and a cover coupled by a hinge, the base and the cover forming an axial passage with a separate inlet and outlet so that the lockbar is retained for movement along the axial passage through the separate inlet and the outlet;
- an input device coupled to the lockbar adapted to selectively move the lockbar between a locked position and an unlocked position,
- wherein the input device is configured to translate a generally horizontal input movement into a generally vertical output movement.

An apparatus for locking a window having a frame, and a sash movable relative to the frame, which comprises:
- a first receiver adapted to be mounted to the sash and a second receiver mounted to the sash, the first receiver having a retaining profile;
- a lockbar adapted to be coupled to the frame and selectively movable between a locked position and an unlocked position;
- a first strike mounted to the lockbar and a second strike mounted to the lockbar;
- at least one lockbar retainer having a base for attachment to the frame and a cover coupled by a hinge, the base and the cover being coupled to provide an axial passage with a separate inlet and outlet so that the lockbar is retained for movement along the axial passage through the separate inlet and the outlet;
- an input device coupled to the lockbar adapted to selectively move the lockbar between a locked position and an unlocked position;
- wherein progressive locking of the sash to the frame is developed as the lockbar is moved from the unlocked position to the locked position, the first strike being engaged with and progressively received and retained along the retaining profile of the first receiver, progressive locking continuing as the second receiver engages and retains the second strike,
- wherein the input device comprises an operator mechanism and a transmitting device coupled between the operator mechanism and the lockbar for translating an input movement of the operator mechanism in a first direction into an output movement of the lockbar in a second direction, and the transmitting device is configured to translate a generally horizontal input movement into a generally vertical output movement.
