In both of these devices, however, the pressure exerted against the object to be captured by the tool comes directly from the pressure of the user's hand squeezing the trigger. 4,709,837 concerns a somewhat similar tool containing a shoe horn and an abutment attached to a movabIe portion at the lower end of the shaft for aiding a person in putting on and taking off their shoes. Such tool is successful for picking up small items. 3,527,492 concerns a tool for use in picking up trash or other items, comprising an elongated shaft having a handle at the upper end and a pair of springs operated pick-up fingers at the lower end. Simply picking up items has been the general subject of many reachers. While young people may undertake and complete such an operation with ease, there are people, such as infirm, aged and even others who cannot maintain a constant grip on the tool handle with such a degree of consistency as to insure their grip will not loosen during the manipulation thereby allowing the item to fall from the grasp of the tool's pickup fingers. Such an operation requires constant pressure applied to the manipulating tool against the object, so that it does not slip away. In addition, there are instances where an item is needed to be carefully moved from one location to another. Instances such as where house keys drop down through a grate, keys locked in a car, and a wallet dropped into a sewer are all instances where direct access to the article is prevented and some retrieval tool is needed. There are times and situations wherein an individual cannot directly use his or her hands to undertake a manipulative operation. In a single hand-actuated pick-up tool of the type comprising an elongated shaft terminating at spaced-apart upper and lower ends, a pair of spaced-apart, pick-up fingers extending from the lower end of the shaft including a pair of springs for biasing them apart, and a pair of ribbons including a handle with a finger-actuable trigger at the upper end, biased apart from the handle, for drawing the fingers together as the trigger is squeezed against the handle, the improvement of providing for the fingers to be able to close together and form locked configurations less than the fully-opened configuration including an arm extending from the trigger for reciprocal motion as a function of movement of the trigger, at least one notch formed in the arm adapted for engagement with a stop in the handle, a spring urging the arm into sliding contact with the stop as the trigger is moved and, a lever pivotally mounted at the upper shaft end for movement between a first unlocked position that permits the spring to retain the arm in contact with the stop and a second, unlock position where the arm is moved out of contact with the stop to permit full range of motion of the fingers from full open to full closed.
