Description: The present invention relates to a device for activating a mobile car stabilizer, designed to move from an idle position, wherein it is housed inside a compartment in the car bodywork, into an operating position wherein it is located outside the contour of the said bodywork and exposed to the air stream flowing over the said bodywork. Known devices for moving a stabilizer from the said first to the said second position comprise a train of articulat­ ed members, a first of which is powered by a motor, and the last of which is connected to the stabilizer in such a manner as to move the same, via a fairly complex move­ ment, from the said first to the said second position. Known devices of the aforementioned type present a number of drawbacks. First and foremost, in addition to being fairly complex in design and cumbersome in size, the said compartment (in which the stabilizer is housed in the said idle position) usually remains open and is therefore ex­ posed to external agents when the stabilizer is moved into the said operating position. The aim of the present invention is to provide a device for activating a mobile stabilizer of the aforementioned type, but involving none of the aforementioned drawbacks, i.e. a device of compact size and highly straightforward construction design, which provides for closing off the said compartment even with the stabilizer set to the said operating position. A further aim of the present invention is to provide a device of the aforementioned type housed inside a cavity formed in the boot lid on the car. With this aim in view, according to the present invention, there is provided a mobile car stabilizer actuating de­ vice, designed to move from an idle position, wherein the said stabilizer is housed inside a compartment in the car bodywork, into an operating position; characterised by the fact that it comprises a movable panel designed to support the said stabilizer by means of at least one rib; an opening in the said bodywork, the edge of which opening presents substantially the same shape as the said stabili­ zer contour and the said panel contour; and actuating means designed to move the said panel from a first posi­ tion, wherein the upper surface of the said stabilizer is substantially flush with the said edge of the said opening which is thus closed off by the said stabilizer, into a second position wherein the said panel is arranged substantially flush with the said edge of the said opening which is thus closed off by the said panel. The present invention will be described by way of example with reference to the accompanying drawings, in which : Fig.1 shows a schematic section of the device according to the present invention in a first position, wherein the stabilizer is arranged in the said idle position; Fig.2 shows the Fig.1 section of the device in a second position, wherein the stabilizer is arranged in the said operating position. The device according to the present invention is designed to move a stabilizer 1 from a first position, as shown in Fig.1 and wherein stabilizer 1 is housed inside a com­ partment 2 formed in the bodywork 3 of the car, into a second position as shown in Fig.2 and wherein the said stabilizer 1 is arranged in an operating position outside the said compartment 2 and exposed to the air stream flow­ ing over the said bodywork 3. In the embodiment shown, the said compartment 2 is formed underneath the boot lid 4 on the car, which, as described in more detail later on, is an ideal location for the de­ vice according to the present invention. The device according to the present invention comprises a panel 5 formed in any appropriate manner, e.g. by means of a pair of sheet metal walls 6 or a second stabilizer formed, for example, from plastic; which panel 5 is de­ signed to support stabilizer 1 by means of at least one, but, in this case, conveniently two ribs 7. The device according to the present invention also com­ prises an opening 8 formed in lid 4, the edge 9 of which opening 8 presents substantially the same shape as the respective contours of stabilizer 1 and panel 5. The con­ tours of the said two parts, which are substantially iden­ tical, are preferably rectangular, but may be of any other shape. Conveniently, surface 10 defining the top of sta­ bilizer 1 is shaped in such a manner as to blend with upper surface 11 of lid 4 when stabilizer 1 is set to the Fig.1 position. The device according to the present invention also com­ prises actuating means for moving panel 5 from a first position, as shown in Fig.1 and wherein upper surface 10 is substantially flush with edge 9 of opening 8 (thus blending with surface 11 of lid 4) and opening 8 is closed off by stabilizer 1, into a second position as shown in Fig.2 and wherein panel 5 is substantially flush with the said edge 9 and the said opening 8 is closed off by panel 5 itself. The said actuating means substantially comprise a crank 15 mounted for rotation about a shaft 19 and controlled by an electric motor 17 via a pair of gears 18. By means of a pin 16, the end of the said crank 15 is hinged to a first point of panel 5, located underneath the said pan­ el 5 and on a bracket 20 integral with the same. The de­ vice according to the present invention also comprises a guide member 21 designed to guide a second point of panel 5 in a given prearranged direction when the said first point is moved by crank 15 in the arc of a circle. The said second point is also located underneath panel 5 and on a bracket 22 integral with the same. The said bracket 22 conveniently comprises a shoe 23 designed to slide inside guide member 21 which is conveniently straight, as shown clearly in the attached drawings. The said actuating means are conveniently arranged on one or both sides of panel 5: crank 15, together with gears 18 and respective motor 17, is arranged on one side, whereas one of guide members 21, together with respective shoe 23, is conveniently located on either side of panel 5. All parts of the said members are housed inside compart­ ment 2, which is closed off at the bottom by a wall 24 integral with lid 4, in such a manner as to enable lid 4 to be opened for enabling access to the boot. The edge 9 of opening 8 is fitted with a sealing member 25 designed to seal with the matching edges of stabilizer 1 and panel 5. The said sealing member 25 conveniently consists of a section of flexible material, for example, having a round cross section, secured in any appropriate manner to edge 9 and designed to be flexed by the respect­ ive edges of stabilizer 1 and panel 5. The device as described operates as follows. When idle, the device is arranged in a first position, as shown in Fig.1, wherein the edge of stabilizer 1 con­ tacts sealing member 25 so as to close off opening 8 in substantially sealed manner. In such a position, upper surface 10 of stabilizer 1 blends with surface 11 of lid 4 so as to form, with the said surface 11, a single unbro­ ken surface. In the same position, crank 15 is located in one of its limit positions, as shown in Fig.1, which corresponds with one of the limit positions of shoe 23 inside guide member 21. For moving stabilizer 1 into its operating position, elec­ tric motor 17 is operated so as to turn crank 15 anti-­ clockwise, and so cause pin 16 on crank 15 (and, conse­ quently, also the said first point of panel 5 hinged to the said pin 16) to move substantially through an arc of a circle. Subsequent to such displacement, and by virtue of the respective ties between shoes 23 and guide members 21, the second point of panel 5 is forced to move in a substantially straight line, and panel 5 is henceforth positioned as dictated by the said ties. In particular, when crank 15 reaches its limit position, as shown in Fig.2, shoes 23 are also located in their respective limit positions inside respective guide members 21, and panel 5 is positioned exactly between edges 9 of opening 8, as shown in Fig.2. In this second position, panel 5 closes off opening 8 in substantially sealed manner, whereas sta­ bilizer 1 is arranged in its correct operating position exposed to the air stream flowing over the car bodywork. By operating electric motor 17 for turning crank 15 clock­ wise, stabilizer 1 may be brought back to its initial idle position as shown in Fig.1. In each of the said two po­ sitions, opening 8 is closed off in substantially sealed manner by virtue of the edges of stabilizer 1 or panel 5 cooperating with sealing member 25 and so preventing water or any other foreign external substances from pene­ trating inside compartment 2. Furthermore, in the said first position, no discontinuity exists on account of the presence of stabilizer 1, whereas, in the second, the po­ sition of stabilizer 1 in relation to the bodywork is identical to that of a stabilizer connected in fixed man­ ner to the bodywork. Finally, the actuating device accord­ ing to the present invention is extremely straightforward, in term of construction design, and highly reliable. To those skilled in the art it will be clear that changes may be made both to the form and arrangement of the vari­ ous component parts of the embodiment described herein without, however, departing from the scope of the present invention. In particular, the form of stabilizer 1 and panel 5, as well as the manner in which the former is con­ nected to the latter, may be other than as described and illustrated herein. Furthermore, the device described may be housed in a compartment formed elsewhere than under­ neath lid 4 of the car boot.
