Abstract: A hooking system for a motorcycle bag is described, comprising a framework, intended to be constrained to a fixed structure of a motorcycle, and a hooking plate, intended to be constrained to the bag. The hooking plate is provided with first fixed hook-shaped hooking means, suitable to hold a first portion of the framework, and second fixed support means, suitable to receive a second portion of the framework opposite to such a first portion. The system comprises moveable hooking means positioned at the second fixed support means and able to be rotatably actuated, by means of a lock mechanism, between a first operative position, to hold the second portion of the framework and keep such a framework hooked to the hooking plate, and a second non-operative position, to release the second portion of the framework and, thus, obtain the disengagement of the bag from the motorcycle.

Abstract: A system is described for hooking and unhooking a carrier bag with respect to the tank of a motorcycle. The system comprises a first group of components suitable to be fixed to the carrier bag and a second group of components suitable to be fixed to the tank. The first group of components comprises a flexible ring provided with a plurality of locking teeth elastically projecting inwards of such a flexible ring. The locking teeth are coupled with an annular flange of the second group of components to obtain the hooking of the carrier bag to the tank. On the flexible ring there is a hand-driven mechanism for the radial retraction of the locking teeth to generate a radial displacement of such locking teeth, allowing disengagement between the flexible ring and the annular flange and, hence, obtaining the disengagement of the carrier bag from the tank.

Abstract: An opening/closing and hooking/releasing system of a suitcase for motorcycles is described, provided with a lower shell and an upper shell. On the bottom portion of the lower shell reversible hooking means to a support plate fixed to the motorcycle are provided. On the lower shell a plaque is made integral, on which are obtained a first release button of the suitcase with respect to the support plate, a second opening button of the upper shell and a locking block. The first and the second buttons are mobile along a predetermined direction. A rotatable under-locking ring is rigidly constrained to the locking block, said ring being provided with a pair of counter-posed protruding teeth and able to rotate in support on the side wall to shift from a first simultaneous blocking position of the first and second buttons to a second simultaneous release position of such first and second button.
