The following invention refers to a suitcase for motorcycles, or similar, provided with a double purpose locking device which assures both the closing of the itslockingtothevehicle.suit@aseand The invention refers also to a method to open a suitcase for motorcycles and to release it from the vehicle by one single security device.

As known, glove compartment suitcases usually put on the bact of motorcycles, or similar, are more and more also,totheintroductionofnewlegalemployed,due, regulations which bind to use crash helmets to protect all riders of said vehicles.

Many specific suitcases have been developed and introduced on the market, for all ranges of two-wheels vehicles, that scooters,etc,eachofismotorcycles, them ownits capacities and functions.

There are, for example, suitcases of limited capacity, employed on mopeds, or low powered vehicles, which are generally fixed to respective supporting plates, integral to the vehicle body, by screw means accessible only from the inside of the suitcase. In such situation, presumably, the suitcase becomes a fixed accessory of the vehicle.

On the contrary, in case the use of it includes frequent installations and removals, the suitcase should show <BR> <BR> <BR> <BR> <BR> interesting and more suitable features of transportability, aestheticpeculiarities.capacityand In this case, it is also provided with faster and more immediate means for connecting to the vehicle: said means can further guarantee the necessary security level against illicitremo-»-als. in fact, in known arrangements, such connecting means are generally protected by key type security means, and in particuitr, most recent solutions allows operating on the same security means employed for the usual opening and closing of the suitcase, offering so a higher level of simplicity and efficacy.

In these last arrangements, the release of the suitcase from the supporting plate is possible by a pression which unhocks said connectif. means. which usually keep the suitcase fixed to above plate by the help of specific elastic means. rr is to notice that, according to the cases, the pression can be effected directly on the key, after turning it in the correct position, or on special knobs, which are however accessible after turning the key. To open the suitcase, it is sufficient to turn the same key in opposite direction, or to release special joint means of its cover, after turning the key.

With this arrangements, the advantage to open the suitcase and to release it by means of the same key is often associated to a certain structural sophistication of the double function adopted device, and to a certain intricacy to open and release the suitcase, for which it is necessary the use of both hands to make it correctly.

One aim of the present invention to propose a suitcase for motorcycles, or similar vehicles, provided with a double function device, for closing and fixing it to the vehicle, of high simplicity and reliability.

Another aim of the invention is to propose a rational and efficient method to open a suitcase for motorcycles and to release it through one single security device.

Further aim of the invention is to propose a suitcase for motorcycles, or similar, provided with a double function device by which the operating ways concerning the two functions may be clearly distinguished, avoiding so to unintentionally release the suitcase from the vehicle instead of opening it, and by which, furthermore, we can get a high security level against possible removal attempts.

Said aims are reached by a suitcase for motorcycles, or similar vehicles, comprising an inferior fixed part, a superior movable part coupled by hinge means to the fixed one, key type security means bound to said fixed part on the opposite side of said hinge means, wherein two levers, shaped as an"L", are jointe, in a rotating way, to said fixed part, and are respectively located above said security means and under said security means, said levers comprising, at one of their ends, hooks which bind the suitcase to the supporting plate and to a member integral to said superior movable part, the other ends being kept in contact, by elastic means, with a cam integral to said key type security means, said cam being rotatable from a central position, corresponding to the closing and locking of the suitcase, to two opposite positions which can produce the opening of the superior part of the suitcase, or the release of it from the supporting plate of the vehicle.

A mechanical stop element is provided to prevent one of said rotations, said element being engaged or disengaged through means located inside the suitcase.

A method to open the suitcase for motorcycles or to release it from the vehicle through one single security device comprises a phase consisting of turning the key in one estabilished direction to open the suitcase, a phase consisting of turning the key in the opposite direction to release it from the vehicle, one of such phases being preceded by a phase cf moving said key in axial sense or by a phase of disengaging a mechanical stop which is placed inside said suitcase to impede said rotation.

It has to be noticed that the possible axial movement of the key has only the role of marking the kind of operation to effect.

The avantages of above suitcase and associated opening and release method are clear ; they are mainly due to the simple structural lay out of the locking device with double function of the present invention.

However, for a better understanding of the structural characteristics and use of the suitcase of the invention, this will now be described by way of embodiment examples, with reference to the accompanying drawings, in which: -figure 1 is a schematic view of the profile, in partial Section, of a suitcase for motorcycles according to the present invention ; -figure 2 is a view, in section, of one portion of the suitcase of fig. 1, in one determined operative configuration ; -figure 3 is one further view, in section, of the portion of the suitcase of fig. 2, in one different configuration; -figure 4 is a view, in partial section, obtained through the section line IV-IV of fig.3- -figure 5 is a view, in section, of one portion of a different embodiment of the suitcase of the invention ; -figure 6 is an interior top view of the portion of the suitcase of fig. 5.

Referring now to fig. 1, it is indicated with la suitcase for motorcycles, or similar vehicles, connected, in a removable way, to a supporting plate, 2, jointed to the vehicle. The suitcase, 1, comprises one inferior fixed part, 3, and one superior movable part, 4, coupled to the fixed one, 3, by hinge means, 5.

The inferior part 3 is provided with one or more back protruding portions 6, which fit with holes, 7, of the 2,and,ontheoppositeside,itissupportingplate provided with an opening, 8, in which a profiled hook, 9, of the plate 2 is insertable. In a further opening, 10, on the Front of the fixed part 3, there is a security locking device, 11, which rotates a shaped cam, 12, shown in figure 4, fixed to the movable part of the locking device, 11, by screw means, 13.

Pressed to said shaped cam, 12, can cas fond the ends 14, 15, of two leviers 16,17, shaped as an"L", turning around two hubs 18,19, supported bv two internal walls 20,21, of the fixed part 3. Said levers 16,17, are in contact with the cam, in, thanks to two respective elastic means s 22,23, which are working between the levers and the corresponding hubs.

As see, the other two ends 24, 25, of said levers 16,1"are shaped so that they can bound respectively with "U"member, 26, integral with the movable superior part 4 of the suitcase, and with the profiled hook, 9, of the supporting plate, 2.

An auxiliary internal wall 28, together with the other 21,protecteandseparatestheabovememberswalls,20, from the useful space of the suitcase.

As per figures 3 and 4, the two ends 24,25, of the shaped levers 16,17, are bound with the corresponding members of the cover of the suitcase and of the plate when the shaped cam 12 is in the neutral position shown in said figures, that is the vertical position of the key 27. Such position is corresponding both to the closing of the suitcase and to its locking to the vehicle.

An anticlockwise rotation of 90 degrees, in the plane of fig. 4, brings the cam 12 in the position shown in figure _. Following to such rotation, the end part, 15, of the lever, 17, goes down, so we have the release of the other end,, of the same lever from the hook, 9.

Said rotation, thanks to the special profile of the cam 12, does not cause any movement of the lever 16, so it is assured that the suitcase remains closed during the disengaging from the supporting plate 2.

It is clear that the rotation in opposite sense of the cam, in respect of the neutral position, causes the release of the lever 16 from the member 26 integral with the superior part of the suitcase, while the position of the lever 17 remains unchanged, therefore, in this case, we have just the opening of the suitcase, without its release from the vehicle.

So the different functions of opening and release of the suitcase are very easy to obtain with the above disclosed embodiment.

Moreover, in order to avoid the case that one of the two <BR> <BR> operations is effected unintentionally, the security means, cas can assure, according to known technics, that one of the two rotations from the neutral position can be done only after the movement in axial sense of the key, according to precise and limited extensions, which amount can be perceived by comparing, in fig. 3, the dotted position of the key 27 in respect to the marked position.

So, adopting the above solution it is possible to define a method of opening and/or release of the suitcase from the vehicle singlekeysecuritydevice,thatcomprisesaone pnase of rotation of the key in one estabilished direction to open it, and a phase of rotation of said key in opposite direction to release it from the vehicle, one of said phases being anticipated b-, a phase of movement of the key in axial sense, in order to distinguish the kind of operation to effect.

In order to avoid that someone may unintenionally release the suitcase from the vehicle, instead of opening it, or vice versa, according to the above described solution, the rotation of the key in the direction useful to get the release of the suitcase can be done only after a small movement of the key main bodv, in axial sense, towards the interior of the suitcase. without causing any displacement of the shaped cam, 1. and, the less, of the"L"levers, i, moved by said cam.

A further solution to the above problem is shown in figs. 5 and 6, which refer to a different embodiment of the invention.

In these figures we note, in fact, that inside the suitcase, 28', there is a vertical thin rod, 30, placed laterally in respect of the vertical median plane; said rod being rotatable around its axis and being provided with a lug, 31. When said rod, 30, is in one of the two terminal positions of its rotation, as per fig. 5, the lug, 31, is situated exactly below the horizontal branch of the"L"lever, 17', in contact of this one, impeding so, any rotation of the lever in the vertical plane; considering that said lever is dedicated to the locking of the suitcase to the supporting plate,'', we have, therefore, a stable locking condition of the suitcase to the vehicle.

When, on the contrary, the vertical thin rod, 30, is put in the other position, rotated of 90 degrees in respect of the above one, the lug, 31, does not interfere at all with any possible rotatory movement of lever 17'around its horizontal pivot; therefore, said lever can move to the release position, shown in fig. b, in consequence of a proper working of the shaped cam, 12', through key means, '1' We can just see that in fig. 6 lug, 31, is located parallel to said horizontal branch of lever 17'and does not interfere with it.

It has to be noticed that, using a special twin dumped cam, we can have, according to known technics, that the key rotation useful to the release of the suitcase may be 90- 100 degrees, from the neutral position of fig. 3, and the key rotation in the opposite sense, useful to the opening of the suitcase, may be 45 degrees approximately. That is, obviously, an important distinguishing factor of the two functions of the locking device of the disclosed suitcase.

So, in this second embodiment of the invention, we have that, when the suitcase is bound to the supporting plate, 2', the usual apening of the same suitcase is achieved through a simple clockwise rotation. of about 45 degrees, of the key inserted in the safety lock, 11'; whilst, when it is desired to take the suitcase away from the vehicle, it has preliminary to put the internal rod, 30, in the proper position, indicated just by word "Open" in fig.5, and, then, it has to rotate the key inserted in safety lock, 11', in anticlockwise direction, for an angle of about 90-100 degrees.

B-yt this last rotation the shaped cam, 12', is moved to the position which causes the displacement of the lever end, 15', towards the bottom and, consequently, the disengaging cf the other end, 25', of the same lever from the profiled 9'.

As already pointed out with regard to the former embodiment, this last rotation, thanks to the special shape of cam, 12', does not cause any movement of the other lever, 16' ; having so the result that during the release of the suitcase from the supporting plate, 2', it continues to stay closed.

In the embodiment of fig. 6, we can note, furthermore, the suitcase-handle, 32, useful to the carrying of the suitcase released from the vehicle, said handle being located, when not in use, in a hello of the suitcase surface, just below the key means, 11'. in the embodimer. of figs. 3, 4 and in the embodiment of figs. 5,6, the operations of closing and locking, thanks to the particular form of the two ends 24,25 of the levers, 16,17 and thanks to elastic means 22,23, are completely automatic ; in fact, for closing it is just necessary to press a bit the superior movable part 4 to the inferior fixed one 3, while to lock the suitcase to the vehicle it is just necessary to press a bit the fixed part 3 to the plate 2, after inserting the protruding portion 6 in the corresponding hole 7 of said plate 2. it is obvious that the ciear and immediate avantages of the suitcase according to the invention remain the same, also if some changes are effected on the disclosed embodiments.

It could be, for instance, that the conformation of the member 26 integral to the cover 4 of the suitcase is different, as long as it remains compatible with the shape and the position of the lever 16, which has to bound it in closing position. The same is for the shaped hook 9,9', compatible with the plate 2.

The elastic means 22,23, which work on the levers, 16,17, can be different from the ones schematicallv shown in fig. a.

Also the capacity and the conformation of the suitcase can be changed from the ones designed in the appended drawings.

Moreover for its structural simplicity and cheapness, the canbeappliedalsotosuitcasesofdisclosedsolution reduced dimensions and price, which, usually, are stable fixed to the vehicle.

In reference to the method of opening and/or release of the suitcase from the vehicle, according to the first embodiment of the invention, the axial movement of the key 27 can be of different extension from the one indicated in fig. 3, and in the meantime, the cam 12 can move accordingly, without interfering with the functionality of the device.

About the second embodiment of the invention some changes may regard the material of the mechanical stop, its manufacturing process or assembly,thewaysofreaching it, from the interior of the suitcase or by external means ; also the contour of the key actuated cam may be altered in order to have different angular displacement of the levers in respect of the ones shown in the drawings.

These and further changements can be made, always within the limits defined by the following claims.
