Abstract: An auxiliary door lock for a dead bolt lock includes a relatively flat rectangular housing for mounting on a door over the interior operating knob of the dead bolt lock; and an actuator slidable and rotatable in an opening in a front wall of the housing. The actuator includes a hollow handle, which is used to rotate the knob. Teeth on the actuator mesh with teeth in the housing in one position of the actuator so that the latter and the knob cannot be rotated when the door is locked. Thus, even using a key, someone outside of the door cannot unlock the dead bolt lock. By pushing the actuator into the housing to a second position, the teeth are disengaged and the actuator can be rotated to unlock the dead bolt lock.

Abstract: In general, latch devices for sliding patio doors are complicated and/or intended to lock a door fully closed. A simple device for latching a sliding door or window partly or fully open or fully closed includes a track for mounting on a frame opposite the side edge of a movable door or window panel; a slide for slidable mounting on the track; a bracket for mounting on the edge of the panel at the bottom thereof; a rod pivotally connected to the slide and to the bracket; a bolt slidable in a recess in the slide body which contains a spring for biasing the bolt outwardly against teeth on the track, the teeth normally permitting movement of the slide in one direction on the track so that the door can be closed but not opened; and a pin for insertion through the slide into the bolt to hold the bolt retracted in the slide, so that the door can move freely between the open and closed positions.

Abstract: An exercise device for the hands and wrists includes an elongated cylindrical body, with a sleeve rotatably mounted on each end thereof and a cord, one end of which is fixedly connected to the body between the sleeves. A weight is mounted on the other end of the cord. By alternately squeezing, rotating and releasing the ends of the body, i.e. by squeezing, rotating and releasing one sleeve and then the other sleeve, the cord is coiled around the center of the body to raise the weight.
