<p>#CMT# #/CMT# The buckle (10) has a pair of superposed rings (11, 12) i.e. rectangular frames of different dimensions, where one of the rings includes a rectangular opening (13) arranged under another rectangular opening (14). The buckle is in position to block a strap in a slot (16) to follow application of clamping force or in releasing position after swiveling movement of the other ring. The latter ring is articulated on the former ring by utilizing a connecting spring (19) to press the latter ring against the former ring and to urge the latter ring slidingly to blocking position. #CMT# : #/CMT# The ring is totally molded from casting in coating made of plastic material. #CMT#USE : #/CMT# Attachment buckle for a strap. #CMT#ADVANTAGE : #/CMT# The buckle provides optimum blocking of the strap to prevent undesirable loss of adjustment, and enables a large opening to be obtained for fitting the strap. The buckle determines pinching effect to prevent loosening when the strap does not include longer taut, and allows possibility of sliding when pulling end of the strap to perform adjustment. The strap is inserted in the buckle in an easy manner by large clearance of the ring with respect to the other ring. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of a buckle. 10 : Attachment buckle 11, 12 : Superposed rings 13, 14 : Rectangular openings 16 : Slot 19 : Connecting spring.</p> |
