INVENTORS EDWARD KAUFMAN GERALD SEIFF BY Iiatented Jan. 1, 1963 3,l?1 .,338 ANTENNA BRACKET FGR PGRTABLE GR MGBILE RADIG COMMUNKCATEON Edward Kaufman, 560 Barron Ave, Weodbridge, Ni, and Gerald Seilf, 134 Bevan Road, Colouia, NJ. Filed lune 21, 195i, Ser. No. 118,713 6 Claims. (ill. 248-43) This invention concerns a bracket for window mounting of a whip antenna.

According to the invention, there is provided a bracket adapted for mounting on a window of an automobile or other vehicle, or on a window of a building. An arm is adjustably carried by the bracket. On the arm is a whip antenna and associated cable. The antenna may be associted with a receiver, transmitter, or transceiver in the short wavelengths ranging from above one and one quarter meters to eleven meters or more. The bracket is adaptable for mounting the antenna above the roof at the center of a Vehicle. No holes need be drilled in the vehicle body. The closing and opening of vehicle doors is unimpaired. The antenna and bracket can be removed and installed without use of any tools. The bracket will mount on any window of a vehicle, building, store display and the like.

It is therefore one object of the invention to provide a bracket for a radio antenna, adaptable 'for adjustable mounting on a window.

A further object is to provide a bracket having a pair of spaced arms provided with adjustable spacing means and adjustably carrying an antenna mounting arm.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a perspective view of a bracket and antenna assembly embodying the invention.

FIG. 2 is a side elevational view of the bracket shown mounted on a window of a vehicle, parts of the window of the vehicle and of the roof of the vehicle being shown in vertical section.

FIG. 3 is a side elevational View of the bracket shown mounted on a window of a building, part of the window and its frame being shown in section.

PEG. 4 is a perspective view of a bar or arm employed in the bracket.

FIG. 5 is a perspective view of another bracket and part of an antenna according to the invention.

FIG. 6 is a sectional view on an enlarged scale taken on line 6-6 of FIG. 5.

PEG. 7 is a top plan view on a reduced scale of part of the bracket of FIG. 5.

MG. 8 is a sectional view taken on line 38 of FIG. 7.

in FIGS 1 and 2 is shown the bracket assembly 1%? including a first bracket member 12 having a straight, flat depending leg 14. Leg 14 is perpendicularly disposed to an intermediate horizontal arm section The leg 14 arm 16 are bent reversely and doubly at 13 and The bends and 29 are such that the upper leg portion id is offset from the plane of leg id. A second L.- shaped bracket member has a depending leg 26 disposed adjacent to leg and an arm 28 parallel and juxtaposed to arm section 16. Leg 26 is spaced from leg 14, but the legs converge inwardly to provide spring action. The member 25 is provided with a section 27 which is doubly bent at 23 and 29 and which is spaced from the offset portion id of leg 14 to define an opening 3%) which is generally triangular in cross'section. The section 27 is disposed at an les of about 35, to both leg 26 and arm 23 so that leg 2% is disposed in a vertical plane while arm 28 is horizontal. Arm 28 is provided with a plurality of longitudinally spaced threaded holes 32 best shown in FIG. 4.

Thumb screws 34 are inserted in elongated closed slots 36 spaced along arm section 16 and are threaded into the holes 32 of arm 28 to secure the member 25 to member 12. Flanges 33 are provided on the thumb screws.

An upright arm section 35 is perpendicularly disposed to arm section 36 at bend 1'7. Spaced threaded holes 37 receive the shanks 39 of thumb screws 46 inserted through holes in a vertical short leg 41 of bracket member 45. Bracket member 35 is L-shaped with a long, straight arm 46 and short vertical leg 41. T he bracket member 45 is adjustably positioned on member 16 since the thumb screws 40 can be located in diilerent holes to raise or lower the member 45 with respect to members 12 and 25. The thumb screws 34 can be selectively located to adjustably position member 25 on member 12 so that leg 26 will be closer to or further spaced from leg 14.

At its outer free end, arm 46 carries a whip antenna assembly 5%. This assembly includes a threaded tube 48 secured vertically by nuts 51, 52 to the arm 46. Threaded, knurled sleeves 53, 54 screw on the upper and lower ends of tube 43. Upper sleeve 53 supports an antenna whip 55 while lower sleeve 54 supports a cable 56 which terminates in a connector 6% adapted to be attached to a suitable coupling element in a radio apparatus.

FIG. 2 shows the bracket assembly 10 supported on a window 62 of a vehicle 64. The bracket arm 46 extends over the roof 65 of the vehicle and can be long enough to locate the antenna assembly 5@ at the central plane of symmetry of the vehicle.

The spaced legs 14 and 26 fit snugly on both sides of the window. Rubber pads may be provided on the inner sides of one or both legs; see pad 61 in PEG. 4, and pads 61, 63 in FIGS. 5, 8. Pad 61 extends over bond 23 and over a portion of section as indicated at 65, and pad 63 covers bend 26 and part of arm section 16 as indicated at 66. The upper arm section 16 is disposed between the upper edge of the window 62 and the bottom of the window frame 66. The cable 56 can be led into the vehicle through the narrow space defined between the top edge of the window and the bottom of the window frame. The window 62 is protected by the extensions 55 and 66 of the pads 63. and 63, respectively.

in FIG. 3, the bracket assembly ill is mounted on window '79 in a building wall The window has a sash frame 74 extended throu h the triangular opening 39 defined between leg sections 14', 2.7 and the upper arm section it). The arm section 16 is located between the window .frame '75 and sash frame 74. The window it; can be raised and lowered without interference by the bracket assembly Ill. The bracket member 45 is turned from its position in FIGS. 1 and 2 Leg 411 has its outer side abutting arm section 35. Thumb screws 49 secure the bracket member 45 in place so that the antenna assembly 5% is supported at the outer end of arm dd spaced away from the building wall 72.

In FIGS. 5-8, the bracket assembly Ill) is modified in that, bracket member 12 is integrally formed with a tubular section 16 and is adjustably secured there by a thumb screw 34 whose shank 34' is threaded in a hole 36 in the top of section 16'. Pads 61 and 63 are provided on legs 14 and 26 which are adjustably spaced and parallel to each other. Another tubular section 41' is integrally formed with leg 41 of bracket member 45". Screw 4W has its shank 39 threaded in a hole 57 and bearing on arm section 35 of member 12*.

The tubular sections 16' and 41' may be formed by bending lateral extensions of the arm section 16 and leg 41* to tubular form. Arm section 35 is adjustably positionable in section 41' and may be secured by screw 45 to maintain the bracket member t5 in a selected fixed position above members 25 and 12 The assembly provides a greater range of adjustments for positioning the bracket member and with respect to the other members 12 than is altorded for members 25 and 45 with respect to member 12 in assembly 10.

The bracket assemblies are mountable on windows and other plane supports without use of any tools, since it is only necessary to loosen and tighten the several thumb screws to mount the assemblies.

The bracket members of the assembly are preferably made of strong lightweight metal such as aluminum. They can be stamped out or formed by conventional metal working machinery at high speed and low cost.

While we have illustrated and described the preferred embodiment of our invention, it is to be understood that we do not limit ourselves to the precise construction herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
