Abstract: A vertical bolt mechanism and installation configuration that avoids damage to a door corner comprises a vertical bolt case of tubular shape and a horizontal tubular transfer case. The mechanism is substantially contained within the bolt case and transfer case. In the installation in a door, the bolt case and the transfer case require only two major holes in the door top and edge, each hole being well spaced from the door corner and the axis of each hold being directed perpendicular to the other. Installation requires insertion of the bolt case through the hole in the top of the door and the transfer case through the hole in the edge of the door. The two cases come together to form an L-shape within the door with the internal mechanism of each case joined in engagement. Routing or cutting out of the door at the corner is thus avoided.

Abstract: An automatic locking window latch including a housing for holding a handle with a fully integrated bolt for securing a window, and a catch for engaging the window to release the bolt to secure the window, as well as to hold the bolt open to open the window. The catch may include a catch body, a spring guide, and a trigger pin. The spring guide slideably fits over a post attached to the housing for guiding the catch body and positioning a catch spring. In an unlocked position, an external force acting against the trigger pin causes the catch body to slide from between the bolt and a slide surface of the housing along the post. As the catch body moves past the bolt, bolt springs push bolt extensions of the bolt through the housing and into an adjoining window molding to secure the window. The catch spring presses the catch body against the bolt until the handle pulls the bolt from the locked position.
