A transport device for fitting to the roof of a motor vehicule

Abstract: A transport device for fitting to the roof of a motor vehicle which includes a bearing arm (14) rotatable about a vertical axis between a longitudinal position which provides a seat (16) for the wheel (17) of a bicycle and a transverse position in which it provides support for at least one ski (25) to rest on. A locking arm (15) is rotatable about a longitudinal axis between a raised position for holding the bicycle (18) in a vertical position and a horizontal position in which the arm (15) lies over the arm (14) so as to clamp at least one ski (25) between the two. A rigid rectilinear element (20) is fitted to the bearing arm (15) so as to be extendable, with fastening means (21) for releasably engaging the bicycle (18) in order to hold it in a vertical position.

Description: The present invention relates to a transport device for fitting to the roof of a motor vehicle for carrying one or more skis and/or one or more bicycles. The invention also relates to a combined ski-carrier and bicycle rack to be fixed on the roof of a motor vehicle. Ski carriers are known in the prior art which comprise a support element in the form of a transverse bar which extends from one side to the other of the roof and on which several arms which act to fix one or more skis, aligned longitudinally across the roof of the vehicle, are mounted for rotation in a transverse vertical plane. While ski carriers of the aforesaid type are both efficient and of elegant design, bicycle racks currently on the market are clumsy objects which are difficult to assemble. The object of the present invention is to provide a multifunctional transport device combining the roles of ski carriers and bicycle rack. A further object of the present invention is to provide a compact device, which is both easy to use and of an elegant design. According to a first aspect of the present invention, these objects are achieved by a device having the characteristics claimed in Claim 1. According to another aspect of the present invention, these aims are achieved by a unit having the characteristics claimed in Claim 9. Other important characteristics are claimed in the dependent Claims. Further characteristics and advantages of the invention will become more apparent from the detailed description of one embodiment thereof, given with reference to the appended drawings, provided by way of purely non-limitative example, in which: Figures 1, 2 and 3 are a perspective view, a view from above and a front elevation view respectively, which illustrate schematically a bicycle and a series of skis carried on the roof of a motor vehicle by means of two ski/bicycle transport units, each having a pair of devices according to the present invention; Figure 4 is a view from above of a motor vehicle fitted with a pair of ski/bicycle transport units according to the invention, in a configuration for carrying a bicycle, which is not shown for the sake of simplicity; Figure 5 shows a detail of Figure 4 on an enlarged scale; and Figure 6 is an exploded perspective view of some components of the transport device of the invention. With reference initially to Figures 1 to 3, the roof of a motor vehicle is schematically indicated 10, with two ski/bicycle transport units according to the present invention, each generally indicated 11, fixed thereon in longitudinally spaced positions. Each unit 11 includes a transverse bar 12 as the support element fixed to the roof 10 of the motor vehicle, which element, in this embodiment, is of a type removably fixed by its ends to the sides of the roof 10. It is clear, however, that the bars 12 could alternatively be elements of a different type, for example in form of bars or plates secured by magnets in continuous manner or otherwise across the roof of the vehicle. In the preferred embodiment shown in the drawings, a pair of transport devices, each generally indicated 13, are mounted alongside each other along each bar 12. According to the present invention, each transport device 13 comprises a bearing arm 14, mounted for rotation about a substantially vertical axis in an outer or side position with respect to the roof 10, and a locking arm 15, mounted for rotation about a horizontal axis, in an inner or central position with respect to the roof 10. In the preferred embodiment, each of the locking arms 15 is also mounted so that it is also able to turn about a substantially vertical axis. With reference to Figure 1 in particular, the bearing arms 14 form upwardly concave channel-shape seats 16; as shown in the upper left-hand portion of Figure 1, each seat 16 able to support a respective wheel 17 of a bicycle 18 when the bearing arms 14 are set in a longitudinal direction. The locking arms 15, on the other hand, are turned to a raised position, in order to lock the bicycle 18 and hold it in a vertical position, as will be explained in further detail herein after. Each locking arm 15 is secured to an associated bar 12, for example by means of an articulation element 19 or other securing element permitting the movements stated above and, again according to the invention, has a rigid rectilinear element 20 mounted in extendable manner with respect to the associated bar 15 and bears a fastening element 21 on its free end, for example a clamp or hook which can be fixed to the bicycle 18, preferably to the frame 22 thereof. In the illustrated locking position, the position of the extendable element 20 must be fixed in order to hold the bicycle 18 in a stable vertical position and to prevent it from swaying sideways or moving lengthways, especially when the vehicle is moving. The extendable element 20 therefore has appropriate locking means (Figure 5) such as transverse pins 23, resiliently hinged to engage selectively, in the extended position shown, one of a plurality of holes 24 constituting locking seats formed in the arm 15 for fixing the relative position between it and its extendable element 20. Advantageously, several holes or engagement seats 24 are formed in the arms 15, in order to be able to adapt the position of the element 20, when extended, to the dimensions of the bicycle 18 to be carried. In the example of figure 5, the extendable element 20 slides like a telescope within the arm 15. With reference again to Figure 1, the position of the fastening means 21 relative to the arm 15 or to the fixed point constituted by the pivot 19 can preferably be finely adjusted, so as to match the dimensions of the bicycle to be carried and to prevent any play or relative motion between the bicycle and the support structure thereof, for example by providing a threaded adjustment device 28 at the free end of the extendable element 20. The support arms 14 for the wheels 17 have appropriate locking means (not shown) for releasably fixing their orientation relative to the transverse bars 12, these may be snap engagement or other fixing means operable to lock them in the correct position: that is longitudinal for transporting a bicycle and transverse for transporting skis, as shown in Figure 1. With reference now to the lower right-hand portion of Figure 1, in which the two transport devices 13 are used to carry three skis 25, the two lower bearing arms 14 are rotated so as to be parallel to and over of the transverse bars 12; the upper locking arms 15 are lowered, parallel to and over of the bearing arms 14 so as to clamp and lock the skis 25 in a per se known configuration of prior art ski racks. Horizontal, rotating blocks, indicated 26 are provided for pivoting the bearing arms 14 and could have a lock (not shown for the sake of simplicity) operable securely to close the locking arms 15 in the same way as for ski racks of known kind. Despite the fact that the drawings show a configuration in which only one of the two locking arms 15 is used to hold the bicycle 18 in a vertical position, it is preferable to use both arms in order to prevent the bicycle from moving longitudinally; to this end, the two locking arms 15 will preferably be oriented so as to be outwardly convergent, as shown schematically in Figure 4, with their extendable elements 20 and associated fastening means appropriately secured to the bicycle. In other words, the fastening means 21 should be fixed to the bicycle 18 at an intermediate position between the transverse bars 12, in such a way that at least one of the arms 15 and its associated extendable element 20 locks the bicycle 18 like a tie rod according to whether the vehicle is decelerating or accelerating and thus whether the bicycle is subjected to a force of inertia tending to move it forwards or backwards. With reference, finally, to Figure 6, in one preferred embodiment the locking arm 15 and the bearing arms 14 are both made of a light, rigid material, such as extruded aluminium. The channel-shape seat 16 in the bearing arms 14 is preferably formed of rubber or other resiliently flexible material moulded onto the said arm while, in the same way, a further rubber element 27 is preferably moulded onto the lower surface of the locking arm 15, in order to grip the skis 25 resiliently when the devices 13 are used for this purpose.
