Abstract: Window grill clips which can be used to removably attach window grills to windows. The window grill clip has a window frame segment and a grill segment extending from the window frame segment at an upward inclined angle. An opening is defined through the grill segment. A tang connected to the grill segment has a first leg extending away from the grill segment and a second leg extending from the first leg and back toward the opening in the grill segment. The grill segment may have a tab which extends downward from and end of the grill segment opposite an end of the grill segment connected to the window frame segment. Window frame engagement spikes may be provided on the window frame segment.

Abstract: A door handle assembly comprises an interior handle connected to the interior face of a door, a latch mechanism which is operable between latched and unlatched positions to secure the door, an operator mounted to the door and rotatable with respect to the handle, and a rack and pinion assembly to transfer the rotary motion of the operator to the latch mechanism. The operator includes a tumbler assembly. The rack and pinion assembly may include a rack and two pinions one located at each end of the rack. However, other arrangements are possible including gear trains comprising two or three gears driven by the rack. The rack and pinion assembly may be mounted between a pair of planar members which form part of a housing which is proportioned to fit between the latch mechanism and an interior surface of a stile of a door. The rack and pinion assembly permits the latch mechanism and the operator, which have usually been coaxial, to be vertically offset from each other.

Abstract: A door lock has a latch which is rotatable from a retracted position to an extended position by means of a linkage. A safety button extends from the latch when the latch is retracted. The linkage cannot be moved unless the safety button has been pressed, which occurs when the door is adjacent the door frame. This prevents the latch from extending and so damaging the keeper in the door frame. The linkage also has a notch which cooperates with a tang projecting from the housing. The tang an notch prevent the latch from being rotated from the extended position to the retracted position except by operation of the linkage. This feature makes it difficult to force the lock open without a key. In addition, one or more remote locks may be added to the main lock. With two remote locks it is possible to provide three anchor points for a door.

Abstract: A sliding door lock assembly providing the feature of automatic unlatching if closed when in a latched position along with effective normal operation and burglar resistance. It employs a latch member spring biased to an open position and cammed into a closed or latched position by a lever member. If the latch is in a locked position and is impacted with the door frame upon closing, it is translated and moves the locking lever to an unlocked position. The locking lever includes a jaw portion which engages the latch effectively. The latch is generally T shaped with the head of the T within the housing of the assembly.

Abstract: A vent operator assembly employing a pair of operator arms which simultaneously control the position of an edge opening vent for recreational vehicles and the like. An operator body is secured to the inner side of the recreational vehicle adjacent to the vent opening therein. The body mounts a worm gear extending between a wall of the body and a cup recess in a bridge extending across a sector shaped recess in the body. A pair of operator arms, each including integral gears are journaled in the body from within the sector recess for simultaneous rotation in opposite arcs. The operator arms are relatively rigid except for the outer 16% which is a flexure spring element. Each spring element mounts a roller which engages a track in the edge of the vent cover opposite its hinged side. Upon rotation of a knob connected to the worm gear, the operator arms move simultaneously in the opposite direction to either open or close the vent cover.

Abstract: A window latch and handle assembly exhibiting an attractive appearance while providing a high degree of strength and small size. The assembly employs a pair of body members which are secured to a door or window frame and a unitary handle and latch. The handle extends from one side of the assembly of the two body parts and the latch from the opposite side thereof. A lock member with an elongated arm surface engages a key slot in the handle and latch. When in one orientation, the locking member allows the handle and latch to move laterally against the resistance of return spring and when turned 90.degree., effectively prevents movement of the handle and latch by direct broad area contact with one of the body parts. When rotated 90.degree., the lock member rests in the key slot allowing limited movement of the handle and latch to release the door or window.
