Definitions

  • the invention concerns an antenna particularly suited to be applied on motor vehicles.
  • antennas for motor vehicles essentially 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 is fixed in relation to its supporting base and when it is mounted it positions itself with an inclination which depends on the construction shape of the supporting base and on the position which said base acquires when it is applied to the body of the car.
  • the impossibility of positioning the antenna at different inclinations prevents an optimum exploitation of the same, above all when said antenna is used with a double function both for the reception of radio broadcastings and for two-way transmissions by radiophone.
  • the present invention proposes to overcome such inconveniences.
  • One purpose of the invention is to obtain an antenna particularly suited to be mounted on motor vehicles, equipped with a rod adjustable in inclination in relation to the supporting base by means of which it is applied to the motor vehicle.
  • the rod of said antenna can be locked in any of the adjusting positions in which it can be arranged.
  • the antenna according to the invention presents theft-preventing characteristics such as to prevent the rod from being removed from its supporting base.
  • connection of the rod of the antenna with its supporting base can be performed without using removable connecting means such as screws, locks, plugs and similar.
  • an antenna particularly suited to be mounted on motor vehicles which, in accordance with the main claim comprises a rod connected to a supporting base applied to a surface supporting the antenna and is characterized in that said rod is connected to said supporting base by means of a ball-and-socket joint which is formed by a first ball-and-socket joint element rigidly connected to said supporting base by means of first connecting means and by a second ball-and-socket joint element connected to said rod by means of second connecting means, said first and said second ball-and-socket joint elements revolvingly co-operating with each other in order to permit the orientation of said rod of said antenna in relation to said base and being equipped with contrasting means suited to permit the fixing of said rod in any of the orientation positions achieved by reciprocal interference between said contrasting means, when at least one of said connecting means reciprocally forces said ball-and-socket joint elements.
  • said first ball-and-socket joint element presents a body made of conductive material which is connected to said supporting base and equipped with a pair of rings co-axial with one another and placed at a distance from each other.
  • Said second ball-and-socket joint element comprises an insulating reel having an essentially circular profile and presenting a seat wherein is inserted a conductive plate, the extremities of which protrude in relation to said insulating reel and co-operate with the inner surface of said co-axial rings of said first ball-and-socket joint element, said insulating reel being coupled by rotation within a housing having an essentially circular profile, obtained in said first ball-and-socket joint element in the area comprised between said co-axial rings.
  • Said insulating reel and said conductive plate are connected to the rod of said antenna.
  • the rod is locked because of the reciprocal interference between the toothed elements, joined together and co-operating with one another, which belong to said co-axial rings of said first ball-and-socket joint element and to said conductive plate of said second ball-and-socket joint element.
  • Said 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, is inserted a plate 73 made of conductive material .
  • said seat 72 is defined inside said insulating reel 71 by the presence of a partition 74.
  • 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 present between said rings 63.
  • Said plate 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 plate 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.
  • the plate 73 has an axial length 573 which is bigger than the axial length 571 of the insulating reel 71, so that when said plate 73 is lodged in the seat 72 of said insulating reel 71, once the latter has been inserted in the housing 64, its extremities 273 protruding from the reel 71 co-operate with the co-axial rings 63 by means of their corresponding toothings, as can be observed in Fig. 4.
  • said conductive plate 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 positions itself co-axial with a corresponding threaded through hole 373 drilled in the body of said conductive plate 73.
  • This latter hole is in turn co-axial with another unthreaded through hole 471 drilled in the partition 74 of the insulating reel 71, wherein said holes are all lined up one after the other.
  • said partition 74 also presents a slit 174 which communicates with its own said through hole 471 and which is suited to yield elasticity and flexibility to said partition in relation to the body of the insulating reel 71 to which it belongs.
  • Said second connecting means of said second ball-and-socket joint element 7 couple with a terminal element, indicated as a whole with 21 belonging to the rod 2 of the antenna and which comprises an essentially cylindrical body, mostly developed following an axial direction, which presents a threaded area 123 obtained in correspondence with said rod 2 and an unthreaded area 124 having a reduced diameter, arranged on the continuity of said threaded area 123.
  • Said terminal element 21 also presents at the extremity a conic terminal element 121 having a bigger diameter than said unthreaded area 124.
  • the antenna according to the invention permits the orientation of the rod 2 in any of the directions shown in the plan of the drawing indicated by the arrow 120. Moreover, any reached position can be maintained because of the reciprocal interference of the toothings 163 and 173 present in the ball-and-socket joint element 5, by tightening the rod 2. This yields the advantage that the antenna can be pointed in the best position, whether it is used as an antenna for the reception of radio broadcastings or as an antenna for the two-way transmission by radiophone.
  • the antenna can also present antitheft characteristics, such as to prevent the rod 2 from being removed from the supporting base 3 to which it is applied.
  • Fig. 7 shows that if the rod 2 is unscrewed from the threaded through hole 373 within which it is coupled and then is lifted up following the vertical direction indicated by the arrow 221, the conic terminal element 121 stops against the elastic partition 74 which prevents the same from being removed and taken away.
  • the partition 74 in fact, cannot be deformed following the direction 221 by the conic terminal element 121, since the presence of the conductive plate 73, which is rigid, prevents any deformation in such a direction.
  • the antenna also presents antitheft characteristics.
  • 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 of the OR type, which is lodged inside an annular groove 161 obtained in the body 62 of said second ball-and-socket joint element 6.
  • FIG. 10 A different embodiment of the ball-and-socket joint element of the antenna is represented in Fig. 10, wherein it can be observed that said ball-and-socket joint 50 presents said second ball-and-socket joint element, indicated as a whole with 60, wherein 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 antenna may undergo some modifications concerning its shape, its length, its dimensions in general.
  • 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.
