Definitions

  • a car radio antenna support comprising a base, which is arranged to be fixed to the body of the automobile, and on which the end piece of the antenna is pivotally mounted; this support is characterized in that the end piece is a hollow piece, in which is mounted, preferably removably, a tubular sleeve, preferably metallic, internally comprising means for the removable fixing of the end of the antenna , which is engaged in one of the ends of said sleeve.
  • the hollow end piece is made of synthetic material, for example molded, and preferably colored black; on the other hand, the tubular sleeve is produced from a flat metal part, by bending, then stapling of its close edges along a generatrix of the tubular sleeve.
  • the present invention relates to a antenna support according to patent FPA '8305912 which is distinguished in particular by the production of the tubular sleeve and the hollow end piece, in which said sleeve is mounted.
  • the car radio antenna support according to the present invention is
  • tubular sleeve consists of a molded piece, preferably metallic, which is engaged in the hollow end piece so that it can be easily separated therefrom.
  • the tubular sleeve in the form of a molded part By producing, according to the present invention, the tubular sleeve in the form of a molded part, a substantial reduction in the cost price of the antenna support is obtained, and, at the same time, an increase in the mechanical resistance of said sleeve; by mounting the tubular sleeve in the hollow end piece so that they can easily be separated from one another, we obtain the possibility of being able to adapt, to the same molded sleeves, of low price, in particular thanks to the absence of external finish, hollow end pieces, of different embodiments, in particular having different exterior finishes; as a result, the same molded sleeves can be used with hollow end pieces as well.
  • a molded tubular sleeve, in particular metallic is particularly advantageous for the adaptation, inside this tubular sleeve, of means of different types for the removable fixing of the end of the antenna; in fact, the same type of tubular sleeve molded according to the present invention can be easily adapted, during its manufacture, both for fixing the end of the antenna by screwing, by providing it with an internal thread, as well as for fixing, quickly releasable, the end of the antenna, either using a latching device, such as that illustrated in FIG. 5 of the aforementioned French patent Either using a bayonet coupling, according to the present invention.
  • This latter method of attachment offers in particular the advantage of ensuring precise angular positioning of the antenna relative to the body of the automobile, which is essential in particular in the case of a dipole antenna.
  • Figure 1 is a view of this embodiment, in section through a plane passing through the axis of the antenna and through the axis of the rod for fixing the base of the support on the vehicle body.
  • Figure 2 is a sectional view along line VII-VII of Figure 1 ,.
  • FIGS. 1 and 2 of the appended drawing have been designated by the same references as the homologous components of the embodiments illustrated in FIGS. 1 to 5 of patent FpA 8305912
  • the description of the embodiment illustrated in FIGS. 1 and 2 can therefore be limited to that of the components by which it differs from the embodiments described in the aforementioned French patent.
  • the two ears, 1b1 and 3a are assembled so as to form a rotary bearing, by means of an axis which, in the illustrated embodiment, is materialized by the rod 4a of a bolt, which can be rough, that is to say without finishing, especially at the level of its head 4b.
  • the rod 4a of this bolt freely crosses aligned holes of the ears 3a and 1b1, and it is screwed into a nut 11, immobilized in rotation on the external face of the ear 3a, by engagement of the nut 11, for example hexagonal, in a housing also hexagonal in section, arranged in said ear 3a.
  • the assembly of the tubular sleeve 3, of its ear 3a, of the bolt 4a-4b and of the nut 11 can rotate freely relative to the base 1a-1b and to its ear 1b1.
  • a spring washer 5 is also interposed between the ear 1b1 of the base1b and the head 4b of the bolt which constitutes the axis of the bearing.
  • the face of the washer 5, opposite the head 4b of the bolt, cooperates with the flat face of a thin washer, 16, which is applied against the fixed ear 1b1 of the base 1b; this washer 16 is immobilized in rotation relative to the tubular sleeve 3 and to its ear 3a, in particular by engagement of a lateral appendage 16a in a recess 17, arranged in the external wall of the tubular sleeve 3, at its connection zone with ear 3a.
  • this washer 16 which rubs against the fixed ear, 1b1, when the tubular sleeve 3 pivots relative to said ear 1b1, while the washer 5, which is interposed between the two elements, 16 and 4b, integral in rotation of the tubular sleeve 3, ensures the locking of the rod 4a of the bolt in the nut 11, so as to avoid any loosening of said bolt, which would be due to vibrations and shocks to which the motor vehicle is exposed.
  • a hollow end piece 6, for example made of chromed metal on the outside, is shaped so that it can be engaged, by its left end, the most widely open, over the tubular sleeve 3, so as to come laterally cover the ears 3a and 1b1, the head 4b of the bolt, the opposite end of its rod 4a and the nut 11, as clearly shown in FIG. 2.
  • the antenna fitter first communicates to the latter an axial thrust in the direction of the axis A of the sleeve 3, so that the end piece 8a firstly crosses its bore 3f; for an appropriate angular position of the antenna and its tip 8a, its radial projections, 13a and 13b, then engage respectively in the longitudinal grooves 12a and 12b, which then guide the tip 8a when it crosses the bore 3g sleeve 3; when the radial projections 13a and 13b of the tip 8a have respectively penetrated into the notches 14a and 14b, the turn of the helical spring 18, opposite the tip 8a, comes to rest against the bottom 3h of the blind bore 3g of the sleeve 3, and said tip 8a slightly compresses said spring 18 when the axial movement of the tip 8a continues until the radial projections, 13a and 13b, abut against the left edges (in FIGS.
  • the fitter must then rotate the antenna 8 around the axis A in an appropriate direction to bring the radial projections 13a and 13b respectively opposite the notches 15a and 15b of the notches 14a and 14b; it then releases the antenna 8 and the relaxation of the helical spring 18 has the effect of communicating to the antenna 8 and at its end 8a an axial movement, directed to the right of the figures.! and 2, and having the effect of engaging the radial projections 13a and 13b in the corresponding notches 15a and 15b, where they remain blocked.
  • To remove the antenna from the support just manually perform the same operations, in reverse order from the one they just described.
  • the antenna support according to the present invention also has the following characteristics, already described in the aforementioned French patent application FPA 83 05 912: the base 1a-1b of the support is fixed to the bodywork by a threaded rod 2, which passes right through them, and which is immobilized in rotation relative to said base, as well as by two nuts, 2a and 2b, screwed respectively on the two ends of the rod threaded; the middle part of the threaded rod 2 has a radial projection 2c, of polygonal outline, generally hexagonal, which can slide with the threaded rod 2 in a prismatic recess, of the same cross section, polygonal, arranged in the base 1a-1b; the base comprises a first element 1a, made of plastic, applicable to the bodywork, and a second element, 1b, metallic, applicable to the first element 1a, and serving as a support for the corresponding nut, 2a; finally, a cover 7, for example of molded synthetic material - not shown in
  • the present invention is not limited to the embodiment previously described; it encompasses all of its variants, only a few of which will be indicated, by way of nonlimiting examples.
  • the base 1b and / or the sleeve 3 could each have two ears, provided with holes aligned for the passage of the rod 4a of the bolt, as described in patent 8305912 .
  • the production of the bayonet coupling between the sleeve 3 and the tip 8a of the antenna 8 is also optional material; the helical spring 18 could be fixed to the bottom 3h of the blind bore 3g of the sleeve 3, its other end cooperating directly with the end, flat or suitably shaped, of the tip 8a of the antenna 8.
  • the helical spring 18 could be replaced by other elastic means of equivalent function.
  • the tip 8a of the antenna 8 with a single radial projection such as 13a, the sleeve 3 itself being provided internally with a single guide groove such as 12a, opening into a notch such as 14a .
  • the notches such as' 15a, notches such as 14a could be eliminated, as well as the spring 18. It would then be preferable to provide means producing a braking of the rotation of the antenna 8 around of axis A of sleeve 3.
