Definitions

  • the invention concerns an antenna particularly suited to be applied to motor vehicles.
  • antennas for motor vehicles substantially consist of a base applied to the body of the car and supporting a rod which constitutes the active element of the antenna.
  • the rod of the antenna can be fixed or it can be oriented with respect to the base and it is connected to the base itself by means of removable connection means, for example screws, pins and the like. Therefore, one of the drawbacks of the known antennas is represented by the fact that unauthorized persons can remove the antenna rod from the relevant support with rather simple operations, even if this requires the use of appropriate tools.
  • the present invention is aimed at eliminating the inconvenience described above through the implementation of an antenna particularly suitable for being installed on motor vehicles that should also have antitheft features, that is, features suitable for preventing the removal of the rod from the support base.
  • Another aim of the invention is the implementation of an antenna in which said antitheft features can be provided both on the version with adjustable inclination and on the fixed version.
  • an antenna particularly suitable for being installed on motor vehicles which, according to the main claim, comprises a rod that is suitable for receiving radio-frequency signals and can be connected to a joint element belonging to a support base of the antenna itself and also suitable for being constrained to a support surface and is characterized in that said rod is provided with a terminal element that can be unidirectionally inserted in a through hole obtained in an elastic body belonging to said joint element.
  • the antenna object of the invention can also be oriented and its joint element, which belongs to the support base and to which the rod is fixed, is constituted by a ball-and-socket joint.
  • the antenna object of the invention As can be observed in Fig. 1, the antenna object of the invention, indicated as a whole with 1, comprises a rod 2 connected to a supporting base 3 applied to a supporting surface 4 consisting of the body of a car, for instance.
  • joint element 5 is a ball-and-socket joint, so that the rod 2 can be oriented.
  • the joint element may also be fixed.
  • Said ball-and-socket joint indicated as a whole with 5, visible in better detail in the exploded views of Fig. 2 and Fig. 3, which is composed by a first ball-and-socket joint element 6, connected to the base 3, which co-operates with a second ball-and-socket joint element 7 connected to the rod 2.
  • first ball-and-socket joint element 6 is applied to said base 3 through first connecting means which consist of an annular area 61 arranged at the extremity of the body 62 of said first ball-and-socket joint element 6, said area snap-coupling with a corresponding annular duct 31 visible in Fig. 9 and obtained in the base 3 of the antenna itself.
  • Said first ball-and-socket joint element 6 is made of conductive material and presents a pair of rings 63 co-axial with one another and placed at a distance from each other, which are preferably obtained from a single block in the body 62 of the element itself, and a housing 64, having an essentially circular profile, being defined between said two rings.
  • Said second ball-and-socket joint element 7 comprises, as can be observed in Fig. 3, an insulating reel 71 having an essentially circular profile, which presents a seat 72 within which, as can be observed in better detail in Fig. 4, a toothed element 73 made of conductive material and having a substantially circular profile is inserted.
  • said seat 72 is defined inside said insulating reel 71 by the presence of an elastic body consisting of a plate 74 having a through hole 471 communicating with a notch 174 suited to make it elastic.
  • said insulating reel 71 has an axial length 571 equivalent to the axial distance 563 between the rings 63, so that said insulating reel 71 can be lodged in the housing 64 provided between said rings 63.
  • Said toothed element 73 belonging to said second ball-and-socket joint element 7 and said co-axial rings 63 belonging to said first ball-and-socket joint element 6 are equipped with contrasting means which comprise an outer toothing 173 obtained in said toothed element 73 and an inner toothing 163 obtained in each of said rings 63, wherein said toothings present profiles connected with one another and such as to be able to reciprocally co-operate whenever said first and second elements are joined together. It can be observed in particular in Fig.
  • the toothed element 73 has an axial length 573 which is bigger than the axial length 571 of the insulating reel 71, so that when said toothed element 73 is lodged in the seat 72 of said insulating reel 71, once the latter has been inserted in the housing 64, its ends 273 protruding from the reel 71 co-operate with the coaxial rings 63 by means of their corresponding toothings, as can be observed in Fig. 4.
  • said toothed element 73 and said insulating reel 71 are equipped with second means for the connection to the rod 2 of the antenna which consist of a through hole 371 drilled in the body of said insulating reel 71 which is positioned coaxially with a corresponding threaded through hole 373 drilled in the body of said toothed element 73; a non-threaded through hole 471 is provided at the center of the partition 74.
  • the rod 2 is provided with a terminal element 21 that can be unidirectionally inserted in the fhrough hole 471 obtained in the elastic partition 74.
  • the terminal element 21 comprises a substantially cylindrical body mainly developed in the axial direction and having a threaded area 123 at the end of the rod 2 and a non-threaded area 124 with reduced diameter positioned at the end of said threaded area 123, provided with a conical terminal part 121.
  • the toothed element 73 rests on the elastic partition 74, which yields elastically when the terminal element 21 of the rod 2 unidirectionally pushes the toothed element 73 against the elastic partition 74 itself.
  • the conical terminal part 121 fits in the through hole 471 of the partition 74 and the non-threaded area 124 and threaded area 123 couple in the holes 371 and 373 respectively, said holes constituting the already mentioned second connection means.
  • the antenna has the required antitheft features, since the rod 2 cannot be removed from the support 3 to which it is applied.
  • the rod 2 can therefore be oriented in different directions in any sense on the drawing plane indicated by the arrow 120.
  • the elastic recovery of the partition 74 restores the meshing of the toothings, in such a way as to keep the rod 2 fixed in the reached direction.
  • Fig. 9 which represents the detail of the connection between said first ball-and-socket joint element 6 and the base of the antenna 3, it can be observed that the watertight seal in the area 21 which is below said first ball-and-socket joint element 6 and, therefore, in contact with the supporting surface 4 of the antenna, is ensured by the presence of a gasket 131, preferably an OR, which is lodged inside an annular groove 161 obtained in the body 62 of said second ball-and-socket joint element 6.
  • a gasket 131 preferably an OR
  • said ball-and-socket joint 50 presents said second ball-and-socket joint element, indicated as a whole with 60
  • the insulating reel 710 is equipped with an elastic partition 740 which, instead of being obtained in a single piece with the body of the reel 710, is added to it since it is lodged inside guides 741 obtained in the body of the reel itself ⁇ which receive said elastic partition 740.
  • the shape and dimensions of the ball-and-socket joint which connects the rod to its base may change, as may the shape and dimensions of the contrasting elements of the elements which compose the ball-and-socket joint.
  • these may acquire any shape which, rather than being essentially cylindrical as has been described, it can be spheric so as to permit the orientation of the rod of the antenna in space rather than on the surface.
  • all said possible modifications will fall within the spirit and scope of the present invention.
