    BRIEF DESCRIPTION OF THE INVENTION The object of the present invention is to provide an expandable roof box which, compared with the prior art, provides lower air resistance and less fuel consumption and provides a possibility of considerably reducing the possibilities for transported objects to move inside the roof box.
    In the case of a roof box of the type specified in the first paragraph above, this is achieved by the mechanism according to the invention being self-inhibiting and designed to allow the height of the intermediate part after loading of the object / objects in the roof box to be reduced in height, so that the lid part presses the object / objects against the bottom part or at least significantly reduces the ability of the object (s) to move vertically inside the roof box. If desired, of course, conventional straps can also be arranged inside the roof box for clamping the object / objects.
    Preferably, the mechanism is of the scissor jack type and comprises for each long side of the roof box a rotatable screw, at least two scissor link units driven by the screw, each scissor link unit comprising four links arranged to form a diamond, one corner of the diamond being attached to a nut which is threaded engagement with the screw, and an opposite corner of the rhombus is supported freewheeling by the screw, and the remaining two corners of the rhombus are at least indirectly connected to each of the lower side facing the middle part, and its upper side, towards the lid part. tande side.
    A scissor jack is self-locking, so that an axial pressure on the nut cannot cause the screw to rotate. At least two scissor link units are required on each long side of the roof box to ensure that the height of the intermediate part changes equally at a front and a rear part of each long side when the screws 10 15 20 25 30 35 are rotated. By said opposite corner of the rhombus being attached to the intermediate part and supported by the screw, a rotation of the screw will cause the nut to move along the screw and change the shape of the rhombus in the scissor link unit, so that when the remaining two corners of the rhombus are at least indirectly connected to each of the lower side of the middle part, facing the bottom part, and its upper side, facing the lid part - the height of the middle part changes.
    Preferably, a common drive device is provided for simultaneously driving the two screws to raise and lower the lid part relative to the bottom part. This avoids that the height change of the intermediate part becomes different along the two long sides of the roof box.
    In order to provide an installation which only slightly intrudes on the cargo space in the roof box, it is suitable that the drive device comprises a distribution gearbox, which is connected to each screw via a flexible shaft.
    To facilitate loading of objects into and unloading of objects from the roof box, the drive device suitably comprises a crank for manual operation and / or at least one electric motor.
    Preferably, two electric motors are provided, one for each screw inside the box, and these can then suitably be remotely operated. In a preferred embodiment, the roof box comprises a power source for supplying power to the motors, an electronics unit for controlling the power supply, and a receiver for receiving a signal from a remote control for controlling the electronics unit.
    The power source is suitably an accumulator or a battery. In addition, it is suitable that the roof box comprises a remotely operable lock, which is controlled by the remote control via the electronics unit. This increases the comfort when using the roof box. The intermediate part preferably comprises a height-expandable wall, for example of the corrugated type, and inside the wall a wall-supporting cage with a plurality of circumferential supports, which extend along the contour of the roof box in the horizontal plane, and articulated links connecting adjacent support rings to each other and allowing the intermediate portion to be reduced in height to a minimum when the articulated links are swung away from the vertical position and extended in height to a maximum when the articulated links are vertical. Such a cage is expandable and gives the surface-expandable wall sufficient support for the formed intermediate part to withstand the wind.
    Preferably, the said remaining two corners of the diamond are attached, one to the top and the other to the bottom of the circumferential support rings for the middle part wall. With such a construction, the screw will move axially in the intermediate part during rotation. If desired, however, it is possible that the mentioned two remaining corners of the diamond by means of e.g. carriages can instead move along each of the top and bottom around the support ring for the wall of the intermediate part, whereby the screw remains fixed in place during rotation.
    If the two screws are equipped with their own electric motor, it is advisable that each of them is mounted to be supported by the rhombus corner of the scissor link unit that is free-running on the screw.
    If desired, at least one of the lid part and the bottom part can be provided with an internal elastically deformable lining of foam type to allow the object / objects carried in the roof box to be clamped by the lid part against the bottom part without risking the object / objects to be injured. 10 15 20 25 30 35 Suitably, the roof box is internally provided with brackets for straps or other fastening devices for fixing objects which are transported in the roof box.
    After mounting on a vehicle roof, the roof box has a front end, and to enable opening of the roof box for loading objects into and unloading objects from the roof box, the lid part or bottom part is connected at the front end or along a long side to the intermediate part by means of a hinge .

    DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Figure 1 shows a roof box for protected transport of objects on the roof of a vehicle. The roof box shown is mounted on the roof of a passenger car and comprises a bottom part 1, a lid part 2 and a vertically expandable intermediate part 3 connecting these parts. The intermediate part 3 comprises a mechanism 4 for increasing the height of the intermediate part to its largest possible height measurements shown in Figure 1 and reduce it to the minimum possible height measurements shown in Figure 11.
    According to the invention, the mechanism 4 is self-restraining and designed to allow the height of the intermediate part 3 after loading of the object / objects in the roof box to be reduced in height, so that the lid part 2 presses the object / objects against the bottom part 1 or at least substantially reduces the object / the ability of objects to move vertically inside the roof box. In this way, an expandable roof box is achieved, which compared with known technology provides lower air resistance and less fuel consumption and provides the opportunity for a significant reduction in the possibilities for transported objects to move inside the roof box.
    As best seen in Figures 2, 4 and 5, the mechanism 4 is preferably of the scissor jack type and comprises for each long side of the roof box a rotatable screw 40, at least two scissor link units 41 driven by the screw 40, each scissor link unit comprising four links 42 arranged to form a substantially diamond-shaped figure (Fig. 4). A corner 45 of the diamond is attached to a nut 43 which is in threaded engagement with the screw 46, and an opposite corner 46 of the diamond is supported free-running by the screw 40 by a bushing 44 fixed on each side by means of a locking washer, inside which a non-threaded portion of the screw 40 can rotate. The remaining two corners 47 and 48 of the diamond are at least indirectly connected to each of the lower side 3 of the intermediate part 3, facing the bottom part 1, and its upper side, facing the lid part 2.
    At the two corners 47 and 48 of the diamond, the links 42 forming the sides of the diamond are not connected directly to each other but to a short spacer 49, so that the outermost tip of the diamond is cut off. It is suitable that it is the intermediate pieces 49 which are connected to each of the lower side 3 of the intermediate part 3, facing the bottom part 1, and its upper side, facing the lid part 2. Because the bushing 44 is rotatably fixed to the screw 40, a rotation of the screw will result in the nut 43 and the bushing 44 approaching each other or moving away from each other, whereby the height of the diamond-shaped scissor link unit 41 (i.e. the distance between the diamond corners 47 and 48 ) increases or decreases. In order to avoid that the nut 43 and the bushing 44 are removed too far from each other when the height of the intermediate part 3 becomes as small as possible, the screw 40 can be provided with a stop for the nut. When the height of the intermediate part 3 is as large as possible, the two diamond corners 45 and 46, which lie along the screw 40, have approached each other so much that the diamond can almost be characterized as a narrow, standing rectangle.
    A scissor jack is self-locking, so that an axial pressure on the nut 43 cannot cause the screw 40 to rotate. The height of the roof box can therefore not be changed by itself while driving.
    At least two scissor link units 41 are required on each long side of the roof box to ensure that the height of the intermediate part 3 changes equally at a front and a rear part of each long side when the screws 40 are rotated. By said opposite corners 47 and 48 of the diamond being attached to the intermediate part 3 and supported by the screw 40, a rotation of the screw 40 will result in the nut 43 being moved along the screw 40 and changing the shape of the diamond in the scissor link unit 41, so that when the remaining two corners 47 and 48 of the diamond are at least indirectly connected to each of the lower side 3 of the intermediate part 3, facing the bottom part 1, and its upper side, facing the lid part 2 - the height of the intermediate part 3 is changed.
    The intermediate part 3 preferably comprises a height-expandable wall 30, for example of bellows type, and inside the wall 30 a wall-supporting cage 31 with a plurality of circumferential support rings 32, which extend along the contour of the roof box in the horizontal plane, and articulated links 33 which The adjacent support rings 32 connect to each other and allow the intermediate part 3 to be reduced in height to a minimum when the articulated links 33 are swung away from the vertical position (Fig. 5) and extended in height to a maximum when the articulated links 33 are vertical (Fig. 6). Each of the link elements in the articulated links 33 has one end attached to one of the support rings 32 and its other end attached to an adjacent support ring 32 and is also hinged in the middle.
    Furthermore, two such articulated links 33 are provided at the front end of the roof box, one on each side of a center line of the roof box, and along each long side of the roof box there is a first such articulated link 33 between said front end and the first scissor link unit 41 and a second such articulated link 32 between the second scissor link unit 41 and the rear end of the roof box.
    Such a cage 31 is expandable and gives the surface-expandable expandable wall 30 sufficient support for the formed intermediate part 3 to withstand the wind. Instead of or in addition to being of the bellows type, the wall 30 can also be elastic and preferably consists of a chloroprene rubber such as neoprene or other suitable material. In the preferred embodiment shown, the number of circumferential support rings 32 is five, and the diamond corners 45 of the nuts 43 in the scissor link units 41 are anchored to the middle of these support rings 32, so that the two operating screws 40 extend along the central support ring 32.
    Along one long side of the roof box the fastening of each of the two scissor link units 41 on the lower support ring 32 is provided with a hinge 15 for articulated fastening of the intermediate part 3 to the bottom part 2. Along the other long side of the roof box the fastening of each one of the two scissor link units 41 on the lower support ring 32 provided with means 34 for hooking a hook member 16 in a locking mechanism 17, which is mounted in the bottom part 1 and can be operated with a key. If desired, it is of course possible to instead make the lid part 1 openable from the intermediate part 2 by arranging along the one long side the hinges 15 between the uppermost support ring 32 and the lid part 2 and placing the hooking means 34 along the second long side of the uppermost support ring 32 and arrange the locking mechanism 17 with the hook means 16 in the lid part 1.
    In order to avoid the height change of the intermediate part becoming different along the two long sides of the roof box when raising and lowering the lid part relative to the bottom part, it is suitable that a common drive device 5 is provided for simultaneous driving of the two screws 40. comprising a distribution gear 50 from which two flexible shafts 51 protrude, one to each of the two screws 40. Figure 9 shows that the distribution gear 50 is attached to the rear end of the roof box at the middle of the circumferential support rings 32, but as can be seen from Figure 10, it can also be arranged behind a transverse partition wall 10 in the rear end of the bottom part 1 of the roof box. In both cases, the distribution gear 50 can be driven by hand with a crank 52, which is normally attached to the rear side of the partition wall 10. see e.g. Figure 2. If desired, it is possible to drive the gearbox 50 with an electric motor (not shown). Preferably, however, two electric motors 53 are used, each of which is directly connected to the front end of the screw 40, i.e. the screw end which is closest to the front end of the roof box, as shown in Figures 2, 3, 5 and 7.
    For power supply to the electric motors 53, there is in the rear end of the roof box a beam delimited by the partition wall 10, which houses a power source 11, such as a battery or an accumulator, and an electronics unit 12 for controlling the current to the motors 53. Preferably, a receiver (not shown) for a signal from a mobile remote control 13 (indicated in Figures 2, 3 and 7) integrated in or connected to the electronics unit 12. With the remote control it is thus possible to increase and reduce the height of the intermediate part 3. In order to supply the electronic unit 12 with power in an emergency if the power in the power source 11 should run out, it is suitable that in the rear end of the roof box, as shown in figure 9, there is a connection option 14 for plugging in a power cord from a cigarette lighter socket or directly from the car battery. The remote control 13 can also be designed to allow locking and unlocking of the roof box locking mechanism 17, e.g. in the same way that a lock to a car door is locked and unlocked with a remote control.
    As best shown in Figures 2-8, the bottom part 1 is internally provided with two transverse reinforcements 18 to enable external mounting of transverse mounting accessories for attaching the roof box to a car roof.
    These reinforcements 18 are suitably provided at their ends with brackets 19 for straps or other fastening devices for fixing objects which are carried in the roof box. If desired, in an embodiment of the roof box (not shown), at least one of the lid part 2 and the bottom part 1 can be provided with an internal elastically deformable lining of foam type to allow the object / objects carried in the roof box to be clamped by the lid part 2 towards the bottom part 1 without the object / objects risking being damaged.
    Furthermore, a gas spring 6 shown in Figures 2, 7, 9 and 10 is connected between the bottom part 1 and the intermediate part 3 to carry the total weight of the intermediate part 3 and the top part 2 when the roof box is opened.
    Otherwise, the roof box according to the invention has a shape which is adapted to give a low air resistance. Its front end is rounded both vertically and laterally, and both the bottom part 1 and the lid part 2 are curved in such a way that the roof box forms a substantially symmetrical wing profile in the horizontal plane with the greatest thickness about a quarter 10 15 20 25 30 12 to a fifth from the leading edge. Even laterally, the roof box narrows slightly towards its rear end.
    INDUSTRIAL APPLICATION The invention is applicable to provide an expandable roof box, which compared with known technology provides lower air resistance and less fuel consumption and provides the opportunity to significantly reduce the possibilities for transported objects to move inside the roof box.
