Claims
- 1. A latch assembly that mounts entirely on the exterior of a door and yet is concealed from view and protected by a handle used to open the door, said latch assembly comprising in combination:
- a door;
- an actuating handle including an extended channel of generally concave cross section having two lips joined by a central portion;
- means located on the exterior of said door for mounting said actuating handle to said door for limited pivotal motion about an axis that is parallel to the channel and parallel to said door with the lips of the channel extending toward but spaced from said door;
- first cam means affixed to said actuating handle for pivotal motion with it and having an inclined cam surface that faces generally in a first axial direction and that progresses both axially and circumferentially around the axis;
- second cam means slidably and non-rotatably mounted to the exterior of said door and having an inclined cam surface bearing against the inclined cam surface of said first cam means for producing a translational motion of said second cam means parallel to the axis when said actuating handle is pivoted;
- a latch bolt connected to said second cam means for translational motion with said second cam means parallel to the axis, whereby rotation, in one sense, of said actuating handle about the axis results in translational motion of said latch bolt in one direction and rotation of said actuating handle in the opposite sense results in translational motion of said latch bolt in the opposite direction;
- the two lips and the central portion of the extended channel substantially enclosing a space between the extended channel and said door;
- said first cam means, said second cam means, and said latch bolt located in said space so as to be concealed from view and protected by said extended channel.
- 2. The latch assembly of claim 1 wherein said first cam means further comprise an uninclined cam surface, merging with the inclined cam surface and facing in the first axial direction and that progresses only circumferentially around the axis, and on which said second cam means rides as said actuating handle approaches one extreme of its limited pivotal motion to maintain said latch bolt at a corresponding extreme of its translational motion.
