#CMT# #/CMT# The clasp has a deploying loop (10) whose end is connected to a thread of a strap and another end is connected to a cap (16). A control unit (22) and a locking unit (20) are connected with the deploying loop to maintain the deploying loop in a folded state under the cap or to allow the deploying loop to unfold after a manual actuation of the control unit. A sliding system (26) slides between two extreme positions according to a longitudinal axis of the clasp. Another control unit i.e. button, is placed in a plane parallel to the cap, and is accessible only when the deploying loop is unfolded. #CMT#USE : #/CMT# Extensible strap clasp for a watch. #CMT#ADVANTAGE : #/CMT# The clasp has prolonged service life. The deploying loop can be closed again and locked while keeping another deploying loop open, thus providing appreciably larger length to the clasp and the strap. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a top perspective view of an extensible strap clasp. 10 : Deploying loop 16 : Cap 20 : Locking unit 22 : Control unit 26 : Sliding system. |
