Raynor, Reseda, Calif., assignor to Clear Beam Antenna Corporation, Canoga Park, Calif., a corporation of California Filed Sept. 17, 1959, Ser. No. 840,681 7 Claims. (Cl. 248-43) This invention relates to an antenna mount having a bracket which permits a pivot type mount on top of the roof, a wall mount on the side of a building, and an antenna mount for a chimney.

In the prior art, antenna mounts have generally been single purpose mounts. That is, the individual mounts were made for example, to be mounted only as a pivot mount on top of the roof, as a wall mount on a wall or as a chimney mount. This required every manufacturer and distributor to make and store, respectively, at least three types of antenna mounts. Needless to say, this requires considerably more storage space and capital investment than is required for storing an antenna kit which contains a mount adaptable to -be secured to a roof, wall or a chimney. Throughout the United States the pivot type antenna -lmount is the most common and is used on a flat or slanted roof. However, in the Chicago area, for example, most antennas are mounted on chimneys Whereas in Florida, where tile roofs tend to prevail, most antennas are mounted on the wall of the building structure.

According to the present invention, an antenna mount has been devised that can be sold in a single do-it-yourself kit and with a minimum of extra parts can be mounted on a roof, chimney or wall. In the prior art, three different types of brackets are required Wher-eas, according to the present invention, one type of bracket is adaptable to be mounted on the top of a roof, on a wall, or on a chimney.

It is therefore an object of the present invent1on to provide an improved antenna mount.

it is a principal object of the present inventton to provide an antenna mount bracket which can 'be used in place of three types of brackets, that is, vfor roof mounting, wall mounting, and chimney mounting.

It is a further object of the present invention to provide an antenna mount which Will greatly reduce the required storage space for distributors who will have to stock only one mount instead of the three required in the prior art.

The invention also comprises novel details of construction and novel combinations and arrangements of parts, which will more fully appear in the course of the following description. However, the dra-wings merely show, and the following description merely describes, preferred embodiments of the present invention, which are given by way of illustration and example only.

In the drawings, like reference characters designate similar parts in the several views:

FlG. 1 is a perspective view of a pivot type roof mount embodiment of the invention;

FIG. 2 is a fragmentary view of one of the guy wires holding the mount shown in FIG. 1;

FIG. 3 is a fragmentary side elevational view of the mount shown in FIG. 1;

PIG. 4 is a perspectve view of the invention used as a chimney mount;

FIG. 5 is a view taken along the lines 5-5 in FIG. 4;

FIG. 5 is a perspective view of the present invention used as a wall mount; and

FIG. 7 is a view taken along the lines 7 -7 in FIG. 6.

The present invention is comprised in part of a bracket 2 as used in the various figures to support a tubular antenna mast 20. In FIGS. 143, the braclcet 2 is used in a pivot or roof mount form, which is the most widely used type of antenna mounting means in the United States. As may be noted, the bracket 2 may be conveniently rnade from a square piece of metal of the proper gauge. The first step in making it -is to cut out the square central portion which is used as the guy ring 22 in the pivot type mount. In the same stamping operation, the opening 23 in the guy ring may be made by the cutting of the pinion washers 37 as used in the chimney and wall mounts.

The 'bracket 2, as formed, may consist of two spaced base portions 3 and each of the base portions 3 have a hole 4 for the insertion of a screw or nail therein to secure the bracket to the roof or to a side wall of a building. At each of the outer ends of the base portions 3 are the bent ends 5 vwhich may be conveniently formed in a plane at 45 to the base. The bent end portions 5 each have a hole 6 which are used in the chimney type mount.

In the right angle breaks formed between the base portions 3 and the side walls 9 of the b'racket are the strengthening indentations '7. Inwardly of the two base portions 3 is the cut away portion 8 which is formed by the cutting of the square guy ring 22. The walls 9 on4 each side of the bracket have a cut away portion having edges which are jointed at their highest point to form a downwardly opening ninety degree V-shaped recess 11.

In the upper portions of the side Walls 9 the generally V-shaped recesses '12 are cut and each of said upwardly opening recesses have serrated edges 13. A bolt hole 14, best seen in PIG. 5, is also punched into the two side walls between the top and bottom of the said V-shaped recesses 11 and `12, respectively, and in FIGS. 1 and 3, a bolt 15 is shown extending through h-oles 14 of the walls 9 and the holes 18, shown in FIG. 4, in the tubular mast 20 so as to secure the mast to the bracket. The nut threadedly engaged on the bolt 15 adjacent the second wall is not shown. The tubular mast 26 is thus pivotally mounted in the bracket and is held in a Vertical position by means of the guy wires 25 which are secured at one end in holes 24 of the guy ring 22 and at the other end in a pinion screw eye 30 which is made to serve, according to the invention, as a turnbuckle, Wood screw and pinion. In FIG. 2, the pinion screw eye 30 is used as a 'Wood screw with the pointed threaded end 34 threadedly engaged in the shingle covered roof 31 on which the pivot type antenna mount is typically mounted. The guy ring 22 is supported upwardly on the mast 29 by means of projections 21 extending outwardly of the surface thereof. Also shown in FIG. 1 are the holes 19 extending through the mast 20, the thread holes being used for insertion of the pinion screw eyes to secure the mast to the bracket. The generally horizontal antenna 28 is shown fragmentarily in phantom outline as typically mounted to the mast 20 by a U-clamp 29.

In FIGS. 4 and 5, a second embodimen't of the invention is shown where the two brackets 2 are held in place on the corner of a chimney 32 with the edges forming a ninety degree recess 11 in contact with the ninety degree corner of the chimney. Here, the wires supplied in the 3 kit are used as straps 35, one end of which is secured to a bent end 5 through the opening 6 therein and the other end of the Wire is secured to pinion screw eye 30 which is used here as a turnbuckle. 'the pointed end of the screw 30 is secured to the other bent end 5 by a nut 36 which is used to tighten and hold the strap around the chimney. As shown in PIG. 5, the bent ends 5 have been bent so as to be substantialiy ninety degrees with the straps 35 and at substantially ninety degrees with the surface of the chimney 32.

To support the antenna mast 20 on the chimney, four of the pinion screw eyes 3h are required, two being required to hold the two straps 35 and the other two are used as pinions extending outwardly of the bracket 2 so as to hold the mast tube 2d against the serrations 13 of the bracket. The latter is accornplished by having the hole extend through the eye of the pinion 3h and through the openings 14 in the bracket walls 9: Here, again, bolts 15 are held in place by a nut (not shown) adjacent one of the walls 9. The pinions 3d extend through the openings 19 in the tube 26 and are secured in place by means of a nut 36 with a washer 37 on the pinion 3 between the nut 36 and the tube Zfi. The washers 37, as aforestated, are cut from the center of the guy ring 22.

By having two of the brackets 2 secured tightly to the chimney and, in turn, supporting mast 20, an excellent antenna mount is provided to support the antenna 23 by means of the U-clarnp 29. The mast is held very close to the wall of the chimney in the two V-shaped recesses 12 on the serrations 13 so as to provide a very strong supporting means with a minimum of metal in the brackets and straps.

In FIGS. 6 and 7, the third embodiment of the invention is shown. Here the mast is secured to the brackets 2 in the same manner as in the chimney mount. The difference in the installation is that in this embodiment, the 'base portions 3 of the brackets are secured to the Vertical wall of a building 33 by means of screws 16 instead of the straps 35. lfthere is excessive overhang on the roof of the building, thel brackets will have to be mounted on blocks or other means outwardly of the Wall so that the mast 20 will be outwardly of the roof overhang. Another means of making this installation on the wall is to have the mast extend through a drilled opening in the overhang portion of the roof.

It should be clear that by means of the present invention, three different types of antenna mounts may be inserted into one mount kit with a minimum number of parts. That is, bracket 2 replaces three other brackets and the excessive parts in the kit for any installation are very small in number and inexpensive as compared with the prior art which required three different types of kits and brackets.

By having only one kit for the three different installations, the supplier can much more easily meet the demand of his customers with less storage space and without fear of not having the right type of mount available for the individual demands.

The previous brackets for wall and chimney installations were required to be of heavier material because they had a much longer lever arm effect and, therefore, were more expensive in addition to being adaptable for only 'on type of installation.

Another salient feature of the invention is that in its use a servicernan is permitted to pick the easiest spot on a roof to install an antenna; That is, rather than having to climb on special ladders or work at precarious angles on a given roof, the serviceman may simply select the easiest place on the house to install the antenna and then put it up using the bracket provided in the present invention. Thus, the present invention not only makes the antenna installation easier but also makes it a safer one. Needless to say, installation of the mount in the safer and easier places makes it possible to save a considerable amount of time with a'r'esultingb'en'efit to both the serviceman and the Consumer.

Although the invention has been described and illustrated in detail, it is to be clearly understood that the same is by way of illustration and example only and is not to be taken by way of illustration, the spirit and scope of the invention being limited only by the terms of the appended claims.
