(Cl. Z50-33) 12 Claims.

This invention relates generally to radio antennae and in particular to an antenna unit for mounting on a side portion of a vehicle body and having an antenna member adjustably movable to a position in conformity with the slope or angle of such body side portion.

Antenna units for mounting on various portions of a vehicle body are well known. In order to present a neat appearance it is desirable that the angle at which the antenna member is supported conform substantially with the contour of the vehicle body. Where the antenna member is fixed in the antenna unit, it is evident that the angular position thereof is determined by the angle of the body portion on which the unit is mounted. The position of the antenna member may thus be at wide variance with the contour of the body portion with which it should conform to be pleasing in appearance. This variance in the angular matching of the antenna member with the car body is particularly objectionable where the antenna unit is mounted back of the engine hood since the projecting or sticking out of the antenna laterally away from the vehicle body appreeiably detracts from the neatness and attractiveness of the vehicle.

It is an object of this invention, therefore, to provide an improved antenna unit for mounting on a vehicle body.

Another o-bject 0f this invention is to provide an improved antenna unit for mounting on a Vehicle body in which the antenna member is adjustably movable to conform with the slope or angle o-f the vehicle body.

Another object of this invention is to provide an antenna unit for mounting on the side portion of a vehicle body having an adjustably supported antenna member which is adjustable relative to the vehicle body, but independently of its supporting structure.

Yet another object of this invention is to provide an antenna unit for a vehicle which is compact and rugged in construction, exible in application to a plurality of different makes of vehicles, comprised of a minimum of easily machined parts, and having an antenna member which is easily and simply adjustable to a position conforming to the angle of the vehicle body.

A feature of this invention is found in the provision of a vehicle antenna unit having a supporting member with a cavity therein and an adjustable antenna member pivotally supported on and extending through a wall portion of the cavity, the means for adjusting the antenna memberI being entirely within the cavity to provide 55 for an overall neat appearance of the antenna unit.

Further objects, features and advantages of this invention will become apparent from the following description when taken in connection with the accompanying drawing in which:

Fig. 1 is a fragmentary perspective side view of a vehicle body showing the antenna unit of this invention mounted thereon;

Fig. 2 is a fragmentary front perspective view of a vehicle body showing the antenna unit thereon with the antenna member in changed positions;

Fig. 3 is a vertical sectional view of the complete assembly of the antenna unit; and

Fig. 4 is a front view of the antenna unit as seen along the line 4-4 in Fig. 3.

Referring to the drawing the antenna unit of this invention is shown in Figs. 3 and 4 as including a longitudinally extending mounting or supporting member 5 having a substantially fiat base portion 6 with a laterally projecting rim I0 thereon forming a cavity 1, the open side 8 of which is opposite the base portion 6. The supporting member 5 is of integral constructionand molded in Bakelite or like material, with the studs or holding members 9 and II for securing the antenna unit to a side portion I2 of a vehicle body I3, being bonded in the base portion 6 during the molding operation. The holding member II is of a tubular construction, with the bore I4 therein being in registry with the cavity 'I.

The rim portion I6 or upper end wall of the cavity 'I, as viewed in Figs. 3 and 4, is formed with an aperture II extending therethrough for receiving the lower or lead-in end I8 of a tubular telescopic type antenna member I9. The upper cavity Wall I6 about the top 2| of the aperture I'I is of substantially semi-spherical form to provide a mating seat for an annular shoulder or ball portion 22 formed on the antenna member I 9 at a spaced distance from the lower end I8. The extension of the antenna I9 into the cavity 'I is thus defined by the engagement of the ball portion 22 in the seat 2l. The walls of the aperture I 1 diverge toward the cavity 'I to provide for a pivotal moving of the antenna I9 on the mounting unit 5, the annular seat 2l and ball portion 22 cooperating as a ball and socket pivotal support for the antenna.

Retention of the operative engagement of the ball'and socket support 2I-22 is accomplished by means including a coil spring 23 positioned in the cavity I and arranged in compression about the antenna I9 between the upper cavity wall I6 and a retaining washer 24. The washer 24 is slidably mounted on the antenna member I9 and maintained in a position axially thereof by a holding pin 26 which extends through diametrically aligned apertures 21 formed in the antenna I9, and diametrically aligned slots 23 formed in an insert or connector member 29 to be later fully explained. Intermediate the top wall I6 and the end 3I of the spring 23 are metal washers 32 and 33 which are held against the wall I6, and hence retained in a position axially of the antenna I9 by the pressure of the spring 24. The washer 32 is of a construction to facilitate the pivotal action of the antenna member I9, the washer 3I being slidably engageable over the washer 32 for concurrent movement with the antenna I9. The lead in 34 to the radio receiving apparatus (not shown) enters the cavity 'I through the bore I4 in the tubular holding member I I, and is suitably connected, as by soldering, to the antenna I9 as indicated at 35.

The insert or connector member 29, previously mentioned, has a tubular portion 34 slidably supported within the lower end I8 of the antenna gagement with a threaded adjusting screw 38 for pivotally adjusting the antenna I9. The adjusting screw 38 is positioned coaxially with the axis of the aperture 31 and substantially normal to the base portion 6 and has an adjustment portion 39 at one end which is rotatably supported in a drawn aperture or bearing support 4I provided in a cover plate 42 for the open side 8 of the cavity 1. The cover 42 fits on a shoulder 43 formed on the inner periphery of the laterally extending rim I0. The opposite end 44 of the adjusting screw 38 extends through an elongated aperture 49 in the base portion 6 and into a recess 48 formed in the flat or outer side of such base portion. The screw end 44 has a nut 46 soldered thereon, a spring washer 41 being mounted at such end intermediate the nut 46 and the shoulder 45 formed at the junction of the recess 48 with the aperture 49, the recess being of a depth to completely receive the nut and spring washer therein. The spring washer 41'acts to pull or bias the adjusting screw 38 toward the left, as viewed in Fig. 3, to in turn pull the adjustment portion 39 against the cover 42 to retain the same seated on the member 5 at the shoulder 43. It isevident, therefore, from Fig. Y3 that the cover 42 completely encloses the cavity 1, with only the adjustment portion 39 0f the screw 38 being exposed and accessible for adjusting the antenna.

In the assembly of the antenna unit the member 29 is inserted in the lower end I8 of the antenna member I9, which in turn is inserted through the aperture I1 into the cavity 1 until seating engagement occurs between the ball portion 22 and its corresponding seat 2l. The slots 28 and apertures 21 in the insert 29 and member I9 respectively, are diametrically aligned and faced toward the open side 8 of the cavity 1. The washers 32 and 3|, the spring 23, and retaining washer 24 are then stacked in that order fil) sapeva about the lower end I8 of the antenna member I9, with the pin 26 being extended through the insert 29 and antenna I9 on compressing of the spring 23 between the upper wall I6 of the cavity 1 and the washer 24. The antenna is then rotated about 90 so that the pin 26 extends transversely of the cavity 1 to its position shown in Figs. 3 and 4. This rotation of the antenna I9 positions the axis of threaded aperture 31 in the connector portion 36 normal to the base portion 6 so as to be engageable with the adjustment screw 33. The adjusting screw 38 with the lock nut 46 and Washer 41 removed from the end 44 thereof, is inserted through the opening 4I in the cover plate 42 and threaded in the aperture 31 until the end 44 is extended through the oval shaped opening 49 and into the recess 48. The spring washer 41 is first placed about the end 44 with the nut 46 then being threaded on the screw until the outer face thereof is substantially flush with the end 44 of the screw, or at least until the cover 42 is rmly engaged with the shoulder 43. The nut 46 is then soldered to the adjusting screw 38.

By virtue of the construction and support of the adjusting screw 38 and its relative assembly with the insert or connector member 29, rotation of the screw member, as by means of a screw driver or the like applied at the adjustment portion 39, pivotally moves the antenna I9 in a plane axially of the adjusting screw 38 and substantially normal to the plane of the base portion 6. Since the screw end 44 is movable within the washer 41 and in the elongated slot 49, movement thereof relative to the base portion 6 is provided so that the screw 38 is readily movable into an aligning position with the aperture 31 in the member 29 for all operating positions thereof.

In the mounting of the antenna unit to the side portion I2 of thev vehicle body I3 there is provided a rubber gasket 5I which is attached to the base section 6 by the cooperating action of mating peripheral portions 52 and 53 formed on the gasket 5I and base portion 6, respectively. The gasket 5I is composed of rubber or like material and fits over the entire outer surface of the base portion 6 to completely enclose and cover the nut 46 and washer 41 in the recess 48. With the exible gasket 5I arranged against the body portion I2, any slight relative variations in the respective contours of the body side portion I2 and outer surface of the base portion 6 are compensated for to assure a more secure tting of the member 5 on the vehicle body. The tubular insert member II is extended through but spaced from the body portion I2 with the cooperating nut 5D thereon being iirmly attached to the body I2 by a lock washer 54. From a consideration of Fig. 3, therefore, it is seen that the unit is entirely insulated from the car body I2. To provide for the elimination of any moisture which might seep into the cavity 1 through the aperture I1 or insert bore I4, a drain hole 55 is formed in the lower end wall 69 of the cavity.

lThe antenna unit is initially mounted on the vehicle body to provide for an angular position of the antenna' I9 in conformity with the angle or contour of the vehicle body portion longitudinally thereof, such initial mounting being illustrated in Fig. 1 relative to the' vehicle windshield 56. With the antenna unit thus initially set, adjustment of the antenna to a position in conformity with theangle or contour of the body portion I2 in adirection transversely of the vehicle body is accomplished by manipulation ofthe adjustment portion 39. Thus, as is clearly illustrated in Fig. 2, the initial angular position of the antenna. I9 relative to the slope or angle of the body side portion l2 is shown in dotted lines, with its angular movement transversely of the car body and to a position in conformity withv the angle of such body portion, as accomplished by adjustment of the adjustment screw 38, being indicated in full lines. Referring to Fig. 3 the relative positions of the parts of the adjusting mechanism, when the antenna I9 is inclined inwardly toward the vehicle body is shown in full lines, with their positions with the antenna I9 adjusted outwardly from the vehicle body being shown in dotted lines. In one commercial embodiment of the invention the adjusting mechanism provides for an overall pivotal swinging or travel of the antenna of about 12.

The invention is thus seen to provide an antenna unit for a vehicle which is neat and cornpact in appearance and readily adapted to provide for the adjustment of the antenna member thereof to a position in conformity with the angle or contour of the body of such vehicle. The invention is flexible in application to a plurality of vehicles of different makes to provide for its standardization and hence economy in cost of manufacture. The adjustable means for the antenna are completely and fully*enclosed within the supporting structure therefor, with only the antenna during adjustment being movable relative to the vehicle body.

Although the invention has been described with reference to a specic embodiment thereof it is to be understood that it is not to be so limited since modifications and alterations in the parts and their relative arrangement can be made therein within the full intended scope of the invention as defined by the appended claims.
