Motorcycle case having a mechanism for the securing and closure thereof

Abstract: It comprises a lock (17) intended to block or release at will an engagement member (11) of the lid (3) when the latter is in closed position on the tub part (2) of the case, said tub (2) being provided with a fold-down handle (8) and with means to prevent detachment of the case from a support base (4). The engagement member (11) is linked to the tub part (2) by being hinged to a rod (10) that in its turn is hinged to the handle (8) and to the tub (2), stops being provided to rest against the handle (8) to prevent swinging of the engagement member (11) when the handle (8) is lowered down against the tub (2) and the engagement member (11) is in a lid closing position; the lock (17) is carried by a blocking lever (15) hinged to the tub part (2) and cooperating with an anchoring member (25) which tends to engage a tooth (5) of the support base (4); when the lock (17) is in closed position, at least one latch (18) of said lock (17) immobilizes the handle (8) when the latter is lowered while another latch (19) of said lock (17) immobilizes said blocking lever (15).

Description: The present invention relates to a motorcycle case having a mechanism for the securing and closure which ensures closure of the case, both when it is secured and when it is not secured to the motorcycle, and the same time prevents removal of the case if the closure mechanism is in working position. BACKGROUND OF THE INVENTION The attachment of cases to motorcycles is increasingly frequent, which makes it essential to ensure the inviolability of cases, both in respect of undue opening of the lid and in respect of the case to motorcycle chassis securing device. Known from EP-EP-0 517 265 is a device for closing and coupling carryall cases comprising a mutually hinged shell and counter-shell. The sell comprises a shaped plate linked to lever systems for coupling to said counter-shell and a locking plate to close the device which carries a handle hinged to said shaped plate. DE 42 30 972 discloses a motorcycle case with a base and a lid hinged to said base. There is a handle rotatably mounted by means of two stems in the base. Cooperating with a stop which is operable with a key are two U-shaped guides which allow the handle from being rotated 90º. The lid is attached to the base by two closing pins formed in said base, these closing pins being engaged with respective locking bolts. DESCRIPTION OF THE INVENTION The motorcycle case of the invention has been designed to provide an effective solution to the needs that have arisen. Accordingly, the motorcycle case having a mechanism for the securing and closure includes a mechanism provided with a lock intended to block or release at will an engagement member of the lid when the latter is in closed position on the tub part of the case, said tub being provided with a fold-down handle and with means to prevent detachment of the case from a support base that is integral with the chassis of the motorcycle. According to the invention, said engagement member of the lid is linked to the tub part by being hinged to a rod that in its turn is hinged to the handle and to the tub, stops being provided to rest against the handle to prevent swinging of the engagement member when the handle is lowered down against the tub and the engagement member is in a lid closing position; the lock is carried by a blocking lever that is hinged to the tub part and that cooperates with an anchoring member which tends to engage a tooth integral with the support base upon which the case removably rests; and said lock is hinged to the tub by means of a first pin and to the fold-down handle by means of a second pin, said second pin (12) carrying said engagement member. There exist stops formed in the tub part intended to prevent swinging of the engagement member and the handle when they remain lowered down. The lock has three latches, one of which is intended to be inserted within a recess provided in the fold-down handle and which serves to lock said handle, the rest being engageable with said stops for immobilisation of the engagement member and the blocking lever. It is thus impossible to detach the case from the support base unless the lock is first opened so that the handle can be raised, thus releasing on the one hand the blocking lever and on the other the engagement member. Advantageously, each end of said pin project outwards defining two protruding stops apt to be inserted in two side notches formed in the handle when the latter is in a lowered condition. BRIEF DESCRIPTION OF THE DRAWINGS For a better understanding of all that is set out in the present specification some drawings are attached in which, solely by way of example, a practical example of embodiment of the motorcycle case is shown. In said drawings, Figure 1 is a longitudinal section view of the mechanism of the motorcycle case in closed position; Figure 2 is a view similar to the previous one, with the mechanism in opening position of the lid and the case anchored on the chassis of the motorcycle; Figure 3 is a view similar to the previous ones with the lid closed and the handle raised; and Figure 4 is a view similar to the previous ones, showing the mechanism in the position of closure of the lid and release of the case from the motorcycle chassis, DESCRIPTION OF A PREFERRED EMBODIMENT Said drawings show a case having the general reference -1-, which comprises a tub part -2- and a hinged lid -3-. The case rests on a support base -4- attached to the chassis of the motorcycle, provided with a front tooth -5- and another rear tooth -6-. The front tooth is intended to anchor a closure mechanism which will be described below, while the rear tooth secures a rear projection -7-of the case. The tub part is provided with a fold-down handle -8- hinged around a pin -9-; around said pin is likewise hinged a rod member -10- arranged between the handle, as mentioned, and an engagement member -11- that is in turn hinged around a pin -12- whose ends project from the sides of said member, forming protruding bosses or stops. The side arms -8a- of the handle have notches -13- into which the ends of the pin -12- can be inserted (Figures 1, 2 and 4). The engagement member -11- forms a tooth -11a- on its upper edge intended to secure the lid -3- by virtue of a front groove -14- provided for this purpose (Figures 1, 3 and 4). Under the handle -8- is arranged a blocking lever -15- hinged around a pin -16- and carrying a lock -17-provided with latches -18-, -19- and -20-. Latch -18- is intended to be inserted into a recess -21- provided in the handle -8- when the latter is lowered, to prevent it from being raised, while latches -19- and -20- are retained by stops -22- and -23- of the case, to prevent the blocking lever -15- from swinging forward. The blocking lever in question is elastically biased by a spring (not shown) which tends to place it in a closure position applied against the tub part. This lever presents a notch -24- into which slots a bar -25- which travels axially and which, when the lever is situated against the tub part, engages the tooth -5- and prevents the case from being detached from its support base -4-(Figures 1, 2 and 3). As can be deduced from all that has been outlined and from observation of the drawings, it can be understood that in the closure position (Figure 1), the handle -8- and the lever -15- are blocked. The handle in its turn blocks the engagement member -11-, so that the lid cannot be opened, while the lever -15- blocks the bar -25-, so that the case cannot be detached from the base -4-. Upon opening of the lock -17-, the latches -18-, -19- and -20- release the aforesaid handle and lever, allowing the lid to be opened by moving the engagement member -11- upwards, and allowing the case to be detached by pulling the lever -15- outwards. Independent of the object of the invention shall be the materials used in the manufacturing of the components of the case closure and retention mechanism, their shapes and dimensions and all accessory details which might arise, as long as they do not affect its essential nature.
