Title:
SLIDING DOOR LOCK DEVICE
Document Type and Number:
Japanese Patent JPH10184132
Kind Code:
A
Abstract:

To eliminate a problem regarding the conventional sliding door double lock where only a crescent is locked, resulting in the negligence of locking the double lock, or the locking of both the crescent and the double lock is neglected, because of the double lock attached to a lower stile, so as to be locked by pressing a locking button and released by pressing a releasing button.

An auto lock device 5 is fitted to the lower stile 4c of an outer sash 4, and provided with a stopper 6 for allowing the slide of an inner sash 3 in a closing direction, but not in an opening direction. When the stopper 6 is forced into the lower stile 4c (i.e., into a case 11), an engagement member 9 prohibits the stopper 6 from projecting, thereby allowing both of the inner sash 3 and the outer sash 4 to slide in an either direction. Furthermore, the auto lock device 5 is fitted with a pushbutton 7 to be pressed inside with the inner sash 3 as opened, and when the pushbutton 7 is pressed inside, a releasing means 8 slides, thereby releasing the engagement member 9 and the stopper 6 from each other. As a result, the stopper 6 projects for allowing the slide of the inner sash 3 in a closing direction, but not in an opening direction.
