BAG, SUITCASE AND THE LIKE FOR COUPLING TO MOTORCYCLES

Abstract: The present invention relates to a bag, suitcase and the like which comprises a substantially rigid body (1) which is provided with means (10,17) for removably coupling to a supporting plate (4) and is constituted by two half-­ shells (2,3) which are pivoted to one another and are provided with means for their mutual closure (20,30,31). The peculiarity of the invention resides in that the means for removable coupling have a button-like element (17) which is operatively associated with a plate (10) which can be removably coupled to a hook-like portion (12) of the supporting plate (4). The closure means have a lever (20) which is articulated with a coupling arm (30) for the mutual securing of the half-shells. A single lock element (40) is furthermore provided, which is supported by the lever (20) and is adapted to interact with the button element (17) and with the lever to prevent their actuation when the lock element is in closed position.

Description: The present invention relates to a bag, suitcase and the like for coupling to motorcycles. As is known, bags, suitcases and the like, structured so as to be removably applicable to a motorcycle, so as to allow the user to remove the bag from the motorcycle when required, have been commercially available for a long time. In the known embodiments, two distinct assemblies are usually provided, each having an own actuation lock, for disengaging the bag from the motorcycle and respectively for opening the bag. An example of a bag with an actuation lock for opening and closing the bag is disclosed in DE-A-3716445 issued to Bayerische Motoren Werke AG. This document describes a locking device in form of a clamp, which by means of a spring, is able to close the bag without first unlocking the said bag. This causes considerable constructive complexities and practical difficulties in use which are not positively accepted by the users. The aim of the invention is indeed to eliminate the above described disadvantages by providing a bag, suitcase and the like which has improved means for closing the bag and for coupling the bag itself to motorcycles, so as to make the actuation of said bag extremely rapid and easy while offering the possibility of using a single lock which controls both the means of application to the motorcycle and the means for opening the bag. Within the scope of the above described aim, a particular object of the invention is to provide a bag, suitcase and the like in which the closing means and the means for coupling to the motorcycle integrate in a single actuation assembly, with a reduction in bulk and with considerable constructive simplifications, without thereby limiting its functionality. Another object of the present invention is to provide a bag, suitcase and the like in which the actuation can be performed in a rapid and simple manner and in which it is possible to couple the bag to the motorcycle even when the lock element is already preset in closed position. Not least object of the present invention is to provide a bag, suitcase and the like which can be easily obtained starting from commonly commercially available elements and materials and is furthermore competitive from a merely economical point of view. The above described aim, the objects mentioned and others which will become apparent hereinafter are achieved by a bag, suitcase and the like for coupling to motorcycles, as defined in claim 1. The characteristics and advantages will become apparent from the description of a preferred but not exclusive embodiment of a bag, suitcase and the like according to the invention, illustrated only by way of non-limitative example in the accompanying drawings, wherein: figure 1 is a schematic view of the bag, suitcase and the like according to the invention, applied to a motorcycle; figure 2 is a schematic sectional view of the step of coupling the bag to the supporting plate of a motorcycle, with the lock element in closed position; figure 3 is a schematic sectional view of the bag, illustrating the movement between the small plate and the button element; figure 4 is an exploded view of the small plate and of the button; figure 5 is an enlarged-scale sectional detail view of the means for closing and for coupling to the motorcycles with the lock element in closed position; figure 6 is a sectional view of the closing and coupling means, with the lock element in open position, illustrating in broken lines the opening of the suitcase closing means; figure 7 is a schematic perspective and exploded view of the closure means; figure 8 is a rear view of the detail of the closure means applied to the bag, suitcase and the like. With reference to the above described figures, the bag, suitcase and the like for coupling to motorcycles, according to the invention, comprises a substantially rigid body which is generally indicated by the reference numeral 1; said body 1 is defined by a lower half-shell 2 and by an upper half-shell 3 which are pivoted to one another. The body 1, and more precisely the lower shell 2, defines means for removably coupling the bag to a supporting plate 4 which is fixed to a motorcycle in a per se known manner. Said coupling means comprise a small plate 10 which defines a middle opening 11 in which a hook-like portion 12, protruding from the supporting plate 4, may be removably inserted. Said small plate 10 is slidably accommodated in a recess 13 defined by the lower shell 2, and its end acts against a return spring 14 accommodated in a seat 15 defined by the half-shell. At the opposite edge, the small plate 10 defines a tang 16 which slidably inserts in a button element 17 which is slidably guided in the recess 13 and has a stop tooth 18 cooperating with a portion of the lower shell 2 to prevent an accidental extraction of the button 17. The fact that the tang 16 of the small plate 10 is slidable with respect to the button element allows the bag to be coupled to the supporting plate 4 even when the lock element is in closed position, as will become apparent hereinafter. The bag furthermore comprises means for closing the half-shells 2 and 3 which comprise a lever 20 articulated, at its end, to a bracket 21 which is fixed to the half-shell. More in detail, the bracket 21 is provided with a pair of opposite lugs 22 which define the support for the pivoting pin of the lever 20 and is downwardly provided with a protruding tab 23. An engagement arm 30 is articulated to a middle portion of the lever 20 and ends with an engagement tooth 31 which can engage the upper half-shell 3 so as to close it. An important peculiarity of the invention resides in that there is a single lock element, generally indicated by the reference numeral 40, which is supported by the lever 20 and actuates a single bolt 41 which has a first end 42 insertable below the protruding tab 23 to prevent the opening of the bag closure means and a second end 43 which acts as a stop element for a projection 19 which upwardly protrudes from the button 17 to prevent its movement in the direction which allows the disengagement of the hook 12 from the small plate 10 (to the left in the figures). Another important characteristic resides in that the button 17 passes through a port 50 (figures 7, 8) defined at the free end of the lever, so that said button can be actuated with the lever in closed position. As illustrated in figures 5 and 6, by virtue of the presence of the bolt 41, the single lock element 40 allows, in closed position, to prevent both the actuation of the coupling means, since the button 17 cannot be moved, and the actuation of the lever closure means, since the lever 20 cannot rotate as the end 42 is retained by the protruding tab 23 and consequently does not allow the disengagement of the engagement tooth 31 from the upper half-shell 3. When the lock element is in open position, as illustrated in figure 6, it is possible to act independently and separately on the coupling means, by acting on the button 17, and on the closure means, by rotating the lever 20. From what has been described it can thus be seen that the invention achieves the proposed aim and objects, and in particular the fact is stressed that a bag, suitcase and the like is provided in which the closure means and the coupling means can both be actuated by a single key which allows to simultaneously lock the closure means and the coupling means. With the described arrangement it is furthermore possible to couple the bag to the supporting plate 4 even when the lock element is in closed position, since the small plate 10 is slidably associated with the button 17 so that said small plate, when pressed against the inclined end of hook 12, slides to perform the coupling. Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the scope of each element identified by way of example by such reference signs.
