A sash tilt system for an upper sash of a double hung window includes a mounting bracket sized and shaped to be fixed relative to a lower sash jamb pocket. A sleeve that is configured to be mounted on the upper sash, and a sash link including a first end and an opposite second end. The first end is rotatably coupled to the sleeve and the second end includes a post extending therefrom. The post is at least partially receivable within the mounting bracket such that the sash link is rotatable with respect to the mounting bracket and the sleeve when the upper sash tilts away from an upper sash jamb pocket.

A child safety locking mechanism has first and second movable doors, a fixed frame, first and second latching means and a catching means, the first and second latching means each comprising a retractable rod retractable by unlocking means having secondary locking means which must be unlocked before the unlocking means operates and is unlocked by a rotating, sliding or pressing-in action, the unlocking means may be released by a rotating, sliding or pressing in action, and movement direction to unlock the secondary locking means is different to the movement direction to release the unlocking means. The retractable rod includes a gear rack, and the unlocking means includes a user engaging surface and is connected by a shaft to a gear wheel engaging the gear rack to slidably move the retracting rod when the engaging surface is rotated by an adult.

A device may limit opening of a sash hingedly coupled to a master frame, and includes: a bracket attached to the sash; a first arm having a first end pivotally coupled to the bracket; a second arm having a first end pivotally coupled to the first arm's second end; means for biasing the second arm into a retracted position; and a release assembly. The release assembly is secured to the master frame and includes a hook pivotable between a first position and a second position, which, in the first position, may be releasably received in an opening in the second end of the second arm when the second arm is in the retracted position, as the sash is closed and received within the master window frame. The second arm is disengaged from the hook, permitting full opening of the sash, when the hook is pivoted into the second position.

A locking structure for securing an electronic device includes a body, a worm shaft, a guide rod, a fixing base and a linkage set. When a user wants to connect the electronic device to another device, the user could insert the electronic device into the locking structure which is set on the device. Then, the user pushes down the electronic device to drive the locking structure and the worm shaft of the locking structure would be rotated from a releasing direction to a securing direction. When the user wants to release the electronic device, the user could push it back to the original position. Then, the worm shaft would be rotated from the securing direction to the releasing direction so the user could release the electronic device from the locking structure. Consequently, it is easy to secure or release the electronic device to another device through the locking structure.

A locking device for a container having a hinged lid, comprises a base unit adapted to be fixed to the container and a pivotable unit mounted to the base unit and pivotally movable between open and closed positions. The base unit includes a locking mechanism comprising a casing, a rotatable shaft, a blocking member fixed to the shaft and disposed in the casing, and a rolling member. The pivotable unit is mounted to the shaft of the base unit. The rolling member is provided to move within the casing between a blocking position wherein the rolling member blocks movement of the pivotable unit relative to the casing to prevent unauthorized opening of the lid, and a release position wherein the rolling member moves away from the blocking member to permit the movement of the blocking member relative to the casing thereby permitting opening of the lid.
