Self-emptying bag having a quick coupling buckle assembly, in particular for shoulder-strap
US-7300206-B2Abstract
A self-emptying bag having a quick coupling buckle assembly, in particular for shoulder-strap, has a buckle assembly ( 4 ) comprised of two parts ( 40, 41 ) that are respectively fixed to two sections ( 201, 202 ) of a shoulder-strap ( 200 ) of a bag so that a snatch on the bag, through the flexible transmission ( 30 ), operates the release mechanism and causes the expandable sack to be inflated to upset outside the contents in the bag. Flexible transmission ( 30 ) is connected to a coupling member ( 91 ) movable inside the first part ( 40 ) of the buckle assembly ( 4 ). The two parts of buckle are formed in such a way that first the second part ( 41 ) can be detached from the first part ( 40 ), and then the second part ( 41 ) can be detached from the coupling member ( 91 ) after a traction has been exerted on the coupling member ( 91 ).
