Abstract
A window lock includes a stationary support base adapted to mount to a window frame. The window lock also includes a window-movement blocker mounted on the stationary support base to block selectively movement of a window panel relative to the stationary support base at the option of a user.
Claims22
A lock for a window, the lock comprising
- a blocker-support base adapted to mount to a window frame in a fixed position,
- a window-movement blocker mounted on the blocker-support base to move about an arm-rotation axis between a window-locking position wherein the window-movement blocker is adapted to block movement of a lower panel carried in a window frame to keep the lower panel in mating contact with a sill included in the window frame and a window-unlocking position wherein the window-movement blocker is adapted to allow movement of a lower panel carried in a window frame to move out of mating contact with a sill included in the window frame, and
- a blocker-movement controller including a barrier lock including an anchor and an anchor mover and a barrier-lock actuator configured to provide means for moving the barrier lock in a first stage of movement from a locked position wherein the barrier lock is arranged to engage the window-movement blocker to cause movement of the window-movement blocker relative to the blocker-support base to be blocked to an unlocked position wherein the barrier lock is positioned to lie in spaced-apart relation to the window-movement blocker to free the window-movement blocker to move relative to the blocker-support base so that window-movement blocker is free to move in a second stage of movement in response to a biasing torque applied in a counter-clockwise direction about the arm-rotation axis to the window-movement blocker so that the window-movement blocker moves in a counter-clockwise direction about the arm-rotation axis relative to the blocker-support base from the window-locking position to the window-unlocking position.
A lock for a window, the lock comprising
- a blocker-support base being adapted to mount to a window frame in a fixed position,
- a window-movement blocker including a barrier arm and an arm-rotation axle, the arm-rotation axle defining an arm-rotation axis, and the arm-rotation axle is arranged to interconnect the barrier arm and the blocker-support base to cause the barrier arm to rotate about the arm-rotation axle relative to the blocker-support base between a window-locking position and a window-unlocking position, and
- a blocker-movement controller including a barrier lock coupled to the blocker-support base and configured to move from an unlocked position wherein the barrier lock is positioned to lie in spaced-apart relation to the barrier arm to cause the barrier arm to rotate between the window-unlocking position and the window-locking position toward a locked position wherein the barrier lock is arranged to interconnect the barrier arm and the blocker-support base to block rotation of the barrier arm relative to the blocker-support base and a barrier-lock actuator coupled to the blocker-support base to move relative to the blocker-support base with the barrier lock.
A lock for a window, the lock comprising
- a blocker-support base including a carrier foundation adapted to lie in spaced-apart relation to a window frame in a fixed position, a foundation fastener coupled to the carrier foundation and adapted to mount the carrier foundation to a window frame, and a blocker carrier coupled to the carrier foundation and positioned to lie in spaced-apart relation to the foundation fastener, and the foundation fastener, carrier foundation, and blocker carrier cooperate to form an actuator space therebetween,
- a window-movement blocker including a barrier arm and an arm-rotation axle coupled to the barrier arm and arranged to extend into the actuator space to define an arm-rotation axis, the barrier arm is coupled to the arm-rotation axle and arranged to extend away from the arm-rotation axle in perpendicular relation to the arm-rotation axis, and the barrier arm is coupled to the arm-rotation axle to rotate about the arm-rotation axis between a window-unlocking position wherein the barrier arm is arranged to lie in a first generally vertical plane wherein the arm-rotation axis is arranged to lie in coplanar relation with the first generally vertical plane and a window-locking position wherein the barrier arm is arranged to lie in a second angled plane to cause an acute plane angle to be defined between the first generally vertical plane and the second angled plane, and
- a blocker-movement controller including a barrier lock including an anchor mover configured to provide a biasing force to the barrier lock to bias the barrier lock into a locking position and an anchor coupled to the anchor mover to move therewith, the barrier lock is configured to move between the locking position wherein the anchor is arranged to extend away from the blocker carrier toward the barrier arm to interconnect the barrier arm and the blocker carrier to cause the barrier arm to be blocked from moving relative to the blocker-support base and an unlocking position wherein the anchor is positioned to lie in spaced-apart relation to the barrier arm to cause the barrier arm to move relative to the blocker-support base between the window-locking position and the window-unlocking position, and a barrier-lock actuator coupled to the barrier lock to transfer a button-actuation force to the barrier lock to overcome the biasing force and move the barrier lock from the locking position to the unlocking position.
