9 Claims. `v1

This invention relates to new and useful improvements in antenna mountings and more particularly to antenna mountings for automoblies and similar vehicles whereby an antenna of the telescopic type may be substantially concealed within the vehicle body when the antennisl is fully telescoped.

Prior to the present invention efforts have been made lto mount antennas interiorly of automobile bodies so that the telescopic antennas would be substantially concealed within the bodies when collapsed. However, the slope or curvature of the cowls, fenders and other portions of the automobile bodies vary widely between dierent makes and models and in the absence of a satisfactory standardized mounting that could be used in all cases, considerable time and ingenuity was required to install the antennas within the variously shaped cowls and fenders of the automobiles so that when the antennas were extended they would project outwardly from vthe automobile bodies at the desired angle, normally vertically.

With the foregoing in mind, an object of the invention is to provide a novel mountingv for telescopic antennas which permits the antennas to be installed in the cowls, fenders and other portions of the vehicle body having different slopes or curvatures. y

Another object of the invention is to provide a novel mounting as setforth which is substantially concealed within the body of the vehicle and enables the antenna to be extended in a vertical or other desired direction.

A further object of the invention is to provide a novel antenna mounting having features and characteristics set forth which is of relatively simplified and inexpensive construction, and can be comparatively easily and readily installed.

These and other objects of the invention and the various features and details of the construction and arrangement thereof are hereinafter fully set forth and described with reference to the accompanying drawing, in which:

Fig. 1 is a fragmentary perspective view showing an automobile having installed therein an antenna mounting made according to the present invention.

Fig. 2 is an enlarged sectional view taken on line 2 2, Fig. 1.

Fig. 3 is asectional view taken on line 3- 3.

Fig. 2; and

Figs, 4, 5 and 6, respectively, are views in perspective of certain parts of an antenna mounting made according to the invention.

- 5 and 6, and a base I which may be employed as a housing for suitable mechanism to extend and telescope the antenna sections as desired.

-In accordance with the present invention, a mounting for the antenna comprises a sleeve or the like 8 having an upper portion S of a diameter that will pass through the body opening 2 and a lower portion I 0 of greater diameter than the portion 9 and the body opening 2. At the junction of the portions 9 and IIJ an annular shoulder II isV provided fcircumferentially of the sleeve 8 and the annular surface portion of this shoulder II preferably is arcuately concave in cross-section, for example, as best shown in Figs. 2 and 3 of the drawing.

The sleeve 8 has a bore I2 therethrough to receive the outer tubular member 6 of the antenna and this bore I2, at its lower end, preferably is counterbored as indicated` at I3 to receive the upper end of the antenna base I which preferably is secured to the sleeve 8 in any suitable manner such as, for example, by welding Il.

'I'he concave arcuate surface of the annular shoulder II provides a curved supporting surface for the rocker portions I5 of a support plate I6 (see Fig. 4). The support plate I6 has an opening I'I therethrough for the reduced portion 9 of the sleeve 8 which it surrounds, and at its four corners the said plate I B is provided with upwardly extending projections or lugs I8 arranged to engage against the underside of the automobile body section I, as shown in Fig. 2 of the drawing, when the sleeve 8 is inserted upwardly through the body opening 2. Preferably the projections I8 are tapered as shown so that point contacts are provided between the plate I6 and the underside of the body section I.

It is to be noted that the rocker portions I5 of the plate I6 decline inwardly so that their edges engage the shoulder II adjacent the inner circumference thereof, and this arrangement of the rocker portions I5 of the plate I6 and the arcuate concave configuration of the shoulder I I serve tol retain the rocker portions I5 engaged or seated upon the sleeve shoulder II.

-Furthermore, the provision of the rocker portions I5 permits the plate I6 to be disposed at any angle with respect to the axis of the sleeve `an annular gasket asumo? y 8 and still insure engagement of all of the four projections I8 thereof with the undersurface of the automobile body section i.

overlying the body section I and surrounding the opening 2 and the reduced portion 9 of the sleeve which projects upwardly therethrough. is

I9 of suitable resilient material such as, for example, rubber or the like. Surmounting this gasket i 9 is a substantially semi-spherical member 20 having an opening 2l therein through which extends the reduced portion 9 of the sleeve B. It is to be noted that the opening 2I in the semi-spherical member 2G diverges or flares outwardly from the base of said member, for example, as best illustrated in Fig. of the drawing, so as to provide for the positioning of the sleeve 8 and antenna at various angles with respect to the plane of the'base surface portion of the semi-spherical member Eil, for example, as shown in Fig. 2 of the drawing, thereby enabling the sleeve il and the antenna therein to be mounted with their common axes in the true vertical or other selected position irrespective of the slope or curvature of the automobile body section i.

Overlying the semi-spherical member is a4 cap 22 of generally spherical configuration which surrounds the reduced end portion Q of the sleeve 8 and overlies the member 2u to substantially close the portion of the opening 2i therein which is not occupied by the sleeve 3 (see Fig. 6). The several parts of the mounting are secured together in proper relation with respect to each other and the automobile body section i by means of an internally threaded cap nut 23 which is threaded onto the exterior of the upper end of the reduced portion ii of the sleeve 8, a suitable washer or gasket 24 being interposed between the end face of the sleeve 8 and the nut 23 as shown in Fig. 2.

To install the antenna mounting of the present invention the body opening 2 is drilled at the de.- sired location and the nut 23, cap 22, semispherical member' 2li and gasket i9 are moved from the assembly. The sleeve with the plate I6 thereon is inserted upwardly through the openlng 2 in the vertical or other direction in which it is desired to have the mounted antenna extend until the four upstanding. projections or lugs I8 of the plate I6 engage the undersurface of the body section I- which they will do `by reason of the fact that the plate i8 is rockably supported by the sleeve 8 through the rocker portions I5. The gasket I9, semi-spherical member 20 and cap 22 are then dropped over the protruding end portion of the sleeve 8 and the nut 23 is threaded onto the latter and tightened thereby clamping the assembly together and to the automobile body section I, and since the pressure exerted by tightening the nut 23 is exerted along the axis of the sleeve which is located within the area defined by the upstanding projections or lugs I8 of the plate I6, a ilrm and stable mounting of the antenna in the desired position is insured.

From the foregoing it will be apparent that the present invention provides a novel mounting for telescoping antennas which permits the antennas -to be installed in the cowls, fenders or other body portions of the vehicle having different slopes or curvatures. The invention also provides a novel mounting as set forth which is substantially concealed within the body of the vehicle and enables the antenna to be extended in a vertical or other desired direction. Furthermore, the invention provides a novel antenna mounting having the described features and characteristics which is of relatively simplified and inexpensive construction and can be comparatively easily installed.

While a particular embodiment of the invention has been illustrated and described herein, it is not intended that the invention be limited to such disclosure and changes and modifications may be made therein and thereto within the scope of the claims. l
