Abstract: The present invention provides a mortise lock mechanism, that includes a lock housing adapted for secure positioning within a mortise, first and second locking members positioned within the housing, each having a first end and a hooked second end, an actuator mounted for rotational movement within the housing and adapted for user directed rotational movement, and a motion translating linkage having a first end pivotally interconnected to the first end of the first locking member, a second end pivotally interconnected to the first end of the second locking member. The motion translating linkage is interconnected to the actuating member and adapted for corresponding movement when the actuator is moved. A first bias member interconnects the translating linkage to the housing, whereby the bias member retains the actuator and the translating linkage in a first position absent user force directed to the actuator.

Abstract: An actuator for use in fenestration systems having a swinging sash or door is characterized by the use of a linear member running continuously from an actuating assembly to a locking pin assembly. The linear member can be a flexible linear member, allowing it to convey motion to the locking pin assembly around corners. The locking pin assembly has a moveable locking pin with an actuator and an extension that can engage a keeper. The linear member has multiple actuator engagement sites along its length where the actuator of the locking pin can engage the linear member. The linear member can then be used to move the locking pin with respect to the locking pin assembly so that the extension can engage or disengage a keeper. The locking pin assembly can be mounted on a fenestration frame and the keeper opposingly mounted on a window or door mounted in the fenestration frame.

Abstract: An improved building foundation form system that includes an integral drain and a spacer bar with engagement lugs at each end adapted to engage a T-shaped engagement channel formed in each of the form surfaces of the inner and outer forms.

Abstract: A gate lock device with front and rear units to be mounted on opposite sides of a structure associated with the gate and against which the gate closes. A gravity latch, displaceably mounted in the housing of the front unit, is engageable with a keeper pin. The front and rear units are provided with key-operated locks which are operable to lock and unlock the gravity latch. The rear unit includes an axially displaceable actuator operable to unlock the gravity latch when the key-operated locks are unlocked.

Abstract: A magnetic latch system including a latch assembly and a keeper assembly. The keeper assembly includes a magnetically attractable keeper pin. The latch assembly includes a magnet and a movable internal lever which is arranged to engage the keeper pin to move it away from the permanent magnet. The system may also include a lock to hold the internal lever in a fixed position so that it cannot be moved to move the keeper pin away from the magnet.
