Abstract
The invention provides for an automatically releasing mounting system by dint of which a weight member may be releasably connected to a fishing-line. The mounting system comprises a receptacle resiliently biassed into essentially conical shape. Wall portions of the receptacle are interconnected by a pivotal joint near the upper end thereof, while latch apparatus are provided to releasably connect the lower ends of the wall portions. The latch apparatus include a latch member having a wing formed integral thereto. When the receptacle hits the surface of the water, the relative movement between the water and the wing portion of the latch member will cause moving of the latch member out of the associated latch-catch. Thus the wall portions of the receptacle cooperating in defining the lower aperture of the container can expand. The receptacle including the latch apparatus can be molded as a single essentially flat part. In order to keep this molded part having been correspondingly bended in the conical or cylindrical configuration the pivotal joint is formed by two members associated to one of the wall portions, respectively, and being adapted for releasable mutual engagement.
