Definitions

  • the present invention concerns a fixing device particularly suitable for fixing an antenna to a support surface that is often constituted by the body of a motor vehicle.
  • the present patent also concerns an antenna using the above mentioned fixing device.
  • motor vehicles are usually equipped with an antenna for receiving and transmitting radiofrequency signals for applications like radio station broadcasting activities, mobile telephony or other applications.
  • Said antennas can be arranged on various points of the motor vehicle but in most cases they are positioned on the roof of the motor vehicle, to which they are attached via fixing means.
  • the latter are usually constituted by a base plate, on which the antenna rests, said plate being attached to the body of the vehicle by means of one or more screws.
  • the base plate is positioned on the body of the vehicle, at the height of the hole through which the screw must pass, and is held in this position until the screw is tightened.
  • Said elastic body generally presents a head surface provided with a central through hole and with two or more lateral tabs folded according to longitudinal development axes that are divergent and incident on the surface defined by the head surface, in such a way as to substantially obtain a cap.
  • the head surface is smaller than the through opening provided in the body, while the free ends of the tabs delimit a surface that is larger than the through opening.
  • the elastic body associated with the base plate is passed through the through opening present in the vehicle, starting from the head surface, initially deforming and then returning to its initial conditions when also the ends of the tabs have passed through the opening.
  • the tabs create a first constraint of the antenna to the vehicle, being arranged against the body of the vehicle.
  • a first drawback is constituted by the fact that, since the elastic body is compressed while passing through the through opening, if said compression is excessive it may cause a permanent deformation or, in extreme cases, also cause the tabs to break.
  • this can be such that the free ends of the tabs delimit a surface that is smaller than the through opening, thus losing its capacity to constrain the antenna to the vehicle.
  • the object of the present invention is to overcome all the above-mentioned drawbacks that are typical of the known embodiments.
  • the presence of a casing for containing the elastic body at least partially makes it possible to prevent the tabs of the elastic body from opening out excessively while the device is being screwed, and thus from causing its irreversible deformation or breakage.
  • the casing prevents the insertion of the device that is the subject of the invention in through openings that are too small and that could deform the elastic body or damage it irreversibly.
  • the convexity of the head surface of the elastic body makes it possible to increase its elasticity compared to the equivalent elastic bodies of the fixing devices of known type.
  • the presence of threads on the surfaces delimiting the through holes provided in the base plate and in the elastic body also advantageously makes it possible to obtain that, in case of removal of the antenna from the support surface, the parts of the fixing device are not all separated from one another but, at least as regards the elastic body and the casing, remain attached to the constraining means, thus reducing the risk of loss of the components.
  • the device for fixing an antenna to a support surface S that is the subject of the invention is represented in Figure 1, where it is indicated as a whole by 1 and where it is possible to see that it comprises:
  • the projection of the through opening 4 on the shaped body 8 is contained at least between the free ends 13 of the tabs 11 and contains the head surface 9 of the shaped element 8.
  • the fixing device 1 also comprises:
  • the casing 15, housing the elastic body 7 inside its cavity 17, makes it possible to prevent the lateral tabs 11 of the elastic body 7 from opening out excessively while the device 1 is being tightened to the support surface S.
  • the cavity 17 of the casing 15 is delimited by four walls 171, substantially vertical, for partially containing said tabs, having at the top a C-shaped opening 172 from which the free ends 13 of the tabs 11 (see Figure 5) exit.
  • the outside of the casing 15 has a substantially parallelepiped shape, as shown also in Figure 2.
  • said casing 15 and the base plate 2 present projections and recesses that are mutually conjugated in correspondence with the through opening 4 present in the support surface S.
  • the base plate 2 is provided with a shaped projection 3 that can be inserted in the through opening 4 of the support surface S and is conjugated with the shaped profile of the cavity 17 of the casing 15 through the interposition of the elastic body 7.
  • the first through hole 5 it is created in the shaped projection 3 at the height of its head end 6.
  • the shaped projection 3 presents, as can be observed also in Figure 3, also one or more cylindrical ducts 20 that develop substantially perpendicular to the surface defined by the base plate 2 and that fit in corresponding housings 21 present in the casing 15.
  • cylindrical ducts for example, can be identified on projections belonging to the casing and fit in housings that can be identified on the base plate.
  • the housings 21 present in the casing 15 are created on the lateral surface of the casing 15 itself, but this should not be intended as a limitation for different embodiments, not represented and not described herein, according to which the cylindrical ducts are provided in correspondence with the inner space of the casing.
  • housings if peripheral, are generally constituted by shaped bevels, which in the particular embodiment described herein are created, as already said, at the height of the side corners of the parallelepiped shaping of the casing 15.
  • Said cylindrical ducts 20 advantageously allow the passage of electric wires for the connection of electric/electronic elements present on opposite sides of the base plate 2 and, in particular, serve as devices for retaining the wires.
  • the head surface 9 of the elastic body 7 it presents, as shown also in Figure 4, a convex shaping facing towards the base plate 2.
  • said convex shaping makes it possible to increase the elasticity that is typical of the elastic body 7 belonging to the fixing device 1 that is the subject of the invention.
  • the elastic body 7 also presents, in any section passing through the axis Y defined by the second through hole 10, a substantially U-shaped profile having diverging lateral arms.
  • This configuration makes it possible to achieve the characteristics described in the main claim, that is, to obtain a fixing device where the projection of the through opening 4 on the elastic body 7 can be contained at least between the free ends 13 of the tabs 11 and can contain the head surface of the elastic body 7.
  • tabs 11 are preferably but not necessarily four.
  • the tab may be simply one or there may be any number of tabs in order to increase the degree of grip of the same on the support surface and to reduce their resistance to elastic deformation.
  • Said tabs 11 also present a sharp profile at least in correspondence with their free end 13 and, in cross section, a preferably but not necessarily C-shaped profile.
  • the sharp profile advantageously makes it possible to improve and therefore increase the degree of friction that they achieve when in contact with the support surface S , making it possible to stabilize the constrain of the fixing device 1 with no need to tighten the constraining means 18 excessively.
  • the latter comprise a screw 26 that passes through the first through hole 5, the second through hole 10 and a third through hole 16 present in the casing 15.
  • Said screw 26 is provided with a manoeuvring head 27, projecting from the third through hole 16, and with a free end 28 that is coupled with a nut 29 arranged on the opposite side of the base plate 2 with respect to the shaped projection 3.
  • This constraint advantageously makes it possible to keep said components joined together, in particular the casing and the elastic body, during assembly and during removal of the antenna from the vehicle.
  • the casing can be permanently attached to the screw via the interaction of the edge of the third through hole with a coupling neck present on the screw.
  • the screw can project from the casing at the height of its cavity.
  • this patent obviously concerns also an antenna for vehicles provided with a device for fixing to a support surface according to the details described above.
  • the fixing device 1 that is the subject of the invention is preferably but not necessarily supplied preassembled, which means that it is supplied, as shown in Figure 5, with the constraining means 18 passing through the holes 5, 10, 16 and screwed onto the nut 29 in such a way as to be mutually constrained.
  • the user must therefore arrange the fixing device 1 at the height of the through opening 4 present in the vehicle and push the casing 15 into the opening until the elastic body 7, which during insertion deforms owing to compression at least in correspondence with the free ends 13 of the tabs 11, exceeds the limit of the opening 4 itself and expands again owing to elastic deformation.
  • the fixing device 1 is constrained to the support surface S and cannot be accidentally detached therefrom.
  • the user tightens the fixing device 1 to the support surface S manoeuvring the manoeuvring head 27 of the constraining means 18.
  • the clamping of the constraining means 18, even if carried out with excessive force, does not damage the anchorage of the elastic body 7 and in particular of the side tabs 11, owing to the control exerted on the opening of the tabs by the walls 171 and by the openings 172.
  • the fixing device that is the subject of the present invention achieves all the set objects.
  • the invention also achieves the aim to carry out a device for fixing an antenna to a support surface in which the elastic elements, though using the same materials in the same thickness, are characterized by a higher degree of elasticity than those used in equivalent known devices.
  • construction variants of the fixing device that is the subject of the invention may be carried out.
