PROBLEM TO BE SOLVED: To provide a pop-out type lock handle device for a door that is reducible in cost by simplifying a structure by decreasing the number of components.SOLUTION: A lock handle device 1 comprises a handle case 2, an inner cylinder 3, a lock member 4, a handle 5, a spring member 6, a lock mechanism 7, and a lock unit 8. A locked state is automatically entered by pressing the handle 5 into the case 2. Through rotation of a rotor 14 of the lock, a single dead bolt 15 is driven to a non-lock position through a rotor cam 16 and a joint cam 17 for unlocking. Cams 16, 17 achieve transmission by engagement between engagement parts 25, 26 which has a play. Even when unwanted external force is applied in the locked state in such a direction that the dead bolt 15 is moved to the non-lock position, one end face 42 of a passive engagement part 23 and a drive engagement part 27 enter thrust engagement, so the dead bolt 15 is never pressed in to the non-lock position.SELECTED DRAWING: Figure 1 |
