United States Patent 3,240,863 STANDOFF ROD AND BRACING MEANS FOR ELECTRIC CABLES OR THE LIKE Robert G. Brede, Dows, Iowa, assignor of one-half to Carl A. Aagesen, Dows, Iowa Filed Sept. 16, 1963, Ser. No. 309,109 10 Claims. (Cl. 174-45) This invention relates generally to transmission wire supports and more particularly to a standoff device for lead-in wires of TV antennas.

Where television antennas are used outside of a building, which is the typical practice, it is desirable that the lead-in wires be held in spaced relation to the building structure and antenna mast. For this purpose, various types of standoffs are employed.

It is desirable that standoffs be very inexpensive. However, it is necessary to maintain leadin wires in tension to avoid motion and flexing which would otherwise be created by the wind and would cause eventual failure of the wires. The least expensive and most convenient standoff devices heretofore known have not usually been adequate to maintain the proper tension in the wires.

In many lead-in installations, it is necessary to change directions of the lead-in wire at various places. An example of such a place is that where the lead-in passes across the peak of a roof. It is necessary to locate a standoff at the peak to provide the desired space between the peak of the roof and the lead-in. Yet the standoffs presently available are not strong enough to properly support a lead-in at such a location.

It is, therefore, a general object of the present invention to provide an improved standoff device.

A further object is to provide a standoff device incorporating a brace of very simple and inexpensive construction and which is easily employed without tools.

A further object is to provide a standoff device including a brace which is well suited to mounting both to antenna masts and to building wall structures.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims.

FIG. 1 is an elevational view of a typical embodiment of the present invention as applied to a television antenna rnast.

FIG. 2 is a section through the illustration of FIG. 1 taken along the line 22 and viewed in the direction of the arrows.

FIG. 3 is an elevational view of the brace support plate, the view being taken in the same direction as in FIG. 1.

FIG. 4 is an elevational view of the brace support plate as seen from the right-hand side of the illustration in FIG. 3.

FIG. 5 is an elevational view of the brace wire and the rod 13 as they appear when viewed in the direction of the arrow 5 in FIG. 1.

FIG. 6 is an elevational view illustrating the invention as applied to a building wall.

FIG. 7 is a fragmentary section taken along line 77 in FIG. 1 and viewed in the direction of the arrows.

In FIG. 1, the standoifs are shown closely spaced to conserve space in the drawing. Actually, the present invention, by bracing the standoffs, permits them to be spaced farther apart than could heretofore be successfully done.

Referring to the drawings in detail, a tubular antenna mast or pole 11 having a longitudinal axis 11a is shown having a pair of largely conventional standard standofis 12 mounted thereto. These standoffs include a rod 13 having a threaded inner end portion 14 and having a loop 16 at the outer end. A suitable insulating insert Patented Mar. 15, 1966 ice 17 is provided in the loop and has an aperture therethrough accommodating the television lead-in wire 18. A branch rod 19 is secured to the rod 13 and is formed in a loop 21 at its outer end and also receives a suitable insulating insert 22 having an aperture 23 therein suitable for receiving a lead-in wire. The shape of the apertures in the inserts depends on the type of lead-in wires being used.

The threaded portion 14 of the rod 13 is received in a substantially hollow base 24 which is a metal plate stamped into a shape accommodating mounting to the mast. A thin metal band employed as a fastener has one end fastened to the base 24 by means of rivet 25. The free end is passed around the mast at 26 and passed through the slots 26a in the walls of the base and pulled tight. Ordinarily, the rod 13 is then screwed into the base thereby forcing the portion of the band spanning the slots 26a into engagement with the mast to secure the assembly to the mast.

However, according to the present invent-ion, a brace support plate 27 is disposed between the base 24 and the outer surface of the mast. Also, the end of the rod 13 is pointed as shown at 47. As shown in FIGURE 4, the brace support plate includes an aperture 28 which receives the end portion of the rod adjacent portion 30 of the band which is pierced by pointed end 47 of the rod 13. It hereby positively maintains the vertical position of the support plate.

Additional apertures

28a and 28b are provided and one or the other of these can be used instead of aperture 28 if desired, to accommodate positioning the support plate as desired.

An important advantage of the use of an aperture in the support plate will be described at this point. Ordinarily, when a standoff having a strap, rod, and base similar to that shown in the drawings herein, is mounted to a round pole, the tendency is for the end of the rod to walk or slide out of alignment with the center of the pole before the assembly is tight enough on the pole. Then it cannot be tightened properly. According to the present invention, however, the end 47 of the rod 12 pierces the band at 30 and enters and is guided by a selected one of the

apertures

28, 28a, or 28b, before it gets a chance to go out of alignment. Consequently, the rod 12 can be screwed into the base to whatever extent necessary to secure the assembly to the pole as tightly as desired.

Further according to this invention, a brace 29 is provided. This brace is a continuous wire or rod which is symmetrical with respect to a plane 31 in which lies the axial center line of the mast 11. Beginning at the end 33 of one leg of the brace, there is a short portion 32 which extends in a direction perpendicular to the direction of the wire 18. This first portion extends a short distance whereupon there is a transition at the point 34 to a second portion 36 extending parallel to the direction of the wire 18. This second portion extends a short distance to a point 37 from which a third portion 38 of the rod extends at an angle with respect to the direction of the wire 18. As shown in the drawing, this third, angularly extending portion continues from point 37 a substantially greater distance than the sums of the short distances of the first and second portions to a point 39 where the angle with respect to the direction of the line 18 decreases for a fourth portion 41. As shown in the drawing portion 41 extends at an obtuse angle with respect to said third portion for a short distance and is terminated at a point 42 followed by a fifth portion 43 lying in the same plane 44 as the fourth portion, there being an acute angle between the fifth and fourth portions. The fifth portion then curves inwardly in the plane 44 to the plane 31 of symmetry of the brace, the inclined plane 44 being perpendicular to the plane of symmetry and lying at an acute angle with respect to the direction of the lead-in wire.

It is seen, therefore, that when viewed as shown in FIG. 2, the brace has the general appearance of a triangle with a re-entrant U where the apex of the triangle would ordinarily be. When viewed as shown in FIG. 5, the device has the general appearance of an M. When viewed as shown in FIGS. 1 and 6, the device is generally straight with an obtuse angle at each end.

The distance X in FIG. 1 between the junction 34 and the center 46 of the U is somewhat greater than the distance between the end 47 of the rod 13 and the beginning of loop 16 at point 48. The point 48 may be referred to as a loop junction of the rod 13 and engages the yoke at the center 46 of the U. The second portions 36 of the legs rest on the tabs 49 of the brace support plate, with the first portions 32 of the brace projecting through the apertures 51 of the brace support plate. The brace can be elastically deformed for installation, and when installed, it may remain elastically deformed to some extent, thereby making certain that contact is maintained between the loop junction of the rod and the yoke of the brace. Also, the fact that the yoke portion of the brace lies in the plane 44 which is inclined with respect both to the direction of the wire 18 and the direction of the rod 13 assures that the rod 13 cannot slip out of the yoke. This is because the loop 16 engages the outer face 53 of the yoke portion in a locking relationship. It also prevents the loop 16 from turning, thereby assuring that the rod 13 will not unscrew.

As shown in FIG. 5, the distance between corresponding portions 43 of the two legs where the imaginary line 45 is drawn between them normal to plane 31 is less than the diameter of rod 13. This necessitates an elastic spreading of these portions slightly to install the brace on the rod. When the brace is installed, the portions 43 return to their original state further insuring that the rod is retained in the yoke. The result is that there is a snap action as the brace is mounted on the rod.

By providing two braces as shown in FIG. 1, the proper tension in the wire 18 can be constantly maintained, it being understood, of course, that the apertures in the loop inserts are sufficiently snug on the wire to exert tension thereon.

Referring now more specifically to FIG. 6, the threaded end portion 14 of the standoff rod 13 is threadedly re- Ceived in the fiat member 54, which member may be a part of a building wall or siding or may be a board attached to the building wall, for example. Apertures 56 are provided in spaced relation to receive the leg portions 32 of the brace 29. The distance between the apertures 56 and their distance from the rod 13 can be selected as required to establish the desired mechanical bias on the rod 13. The brace functions in the same manner as described with reference to FIG. 1. Of course the apertures 56 need not extend completely through member 54. However, in certain materials, such as soft pine for example, it is not necessary to provide apertures as such, because the pointed ends 33 of the brace, can be pressed into the material and will securely anchor the legs. Moreover, by making the brace portions 32 comparatively short and pointed, and having the adjacent portion 36 disposed approximately at right angles thereto, the portions 32 can be conveniently driven into harder materials by striking portions 36 with a hammer.

It will be seen from the foregoing discussion that the present invention is well suited to achievement of all of the objectives set forth herein and provides other advantages and benefits which will become apparent to those skilled and working in the art.

While the invention has been disclosed and described in some detail in the drawings and foregoing description, they are to be considered as illustrative and not restrictive in character, as other modifications may readily suggest themselves to persons skilledin this art and within the broad scope of the invention, reference being bad to the appended claims.
