ABSTRACT:
A bolt fits slidably within a cylinder and is inserted in a drilled hole through a first slidable member to be interlocked. The bolt, under force of a coil spring within the cylinder, is forced into any of a series of aligned holes in a second member to be interlocked. A striker plate with aligned holes is attached to the second member and receives the end of the bolt as it slides until forced into a hole. A body is attached to the cylinder and the body is secured to the slidable first member to be interlocked. A D-spring on the body engages a D-spring notch on the bolt, locking the bolt in the projected position, thereby interlocking the two members. The body and handle, attached to the bolt, have flat surfaces which when aligned indicate that the D-spring is engaged to the D-spring notch. The handle must be rotated to disengage the D-spring and D-spring notch before the handle and bolt can be retracted. A secondary pair of D-spring notches forward on each side of the bolt at 90 degrees to the first D-spring notch engage the D-spring to retain the bolt in a retracted unlocked position for free sliding of the two members. Sliding windows, sliding doors, movable shelves and other slidably interactive members may be locked together.
