Northwood, Iowa Application February 11, 1955, Serial No. 487,637

1 Claim. (Cl. 248-48) This invention relates to mounts for television or radio antennas, and more particularly, has reference to an improved mount that summarized briefly, comprises a vertically extending, upwardly opening pipe socket adapted to receive an antenna mast, a plurality of downwardly divergent legs detachably secured to said pipe socket, brace means extending between the legs and the lower end of the pipe socket, and adjustable feet or clips carried by the lower, divergent ends of the legs for adapting the mount for installation on variously pitched roofs.

One object of importance is to provide an antenna mount which will simplify to a marked degree the installation of an antenna the construction being such as to permit a single man to easily and quickly install an antenna in far less time than is regularly required following conventional installation practices.

Another object of importance is to provide an antenna mount as stated which not only will reduce the cost'of installation by the above mentioned reduction in labor cost, but which is at the same time itself composed of easily assembled, simply designed components, thus to reduce the basic cost of manufacture of the device.

Still another object is to so form the antenna as to simplify manufacturing costs and installation procedures without sacrificing ruggedness and durability of the mount.

Another important object is to provide an antenna mount which will eliminate the use of guy wires, the mount being so designed as to support a mast of substantial height without danger of said mast, toppling or bending under heavy winds.

Yet another object is to form the antenna mount with means at the lower end thereof which will permit the adjustment of the same to any pitch of roof, and which will, in fact, permit the mount to be erected on flat roofs as well as in position over the ridge peak of variously pitched roofs.

Still another object is to provide an antenna mount which will, when erected, have a more attractive appearance than conventional mounts now in use.

A further object is to provide an antenna mount of knockdown characteristics, which can be shipped in a relatively small carton, and which can be swiftly assembled when it is to be installed.

Other objects will appear from the following description, the claim appended thereto, and from the annexed drawing, in which like reference characters designate like parts throughout the several views, and wherein:

Figure 1 is a perspective view of an antenna mount formed in accordance with the present invention, as it appears when in use;

Figure 2 is an enlarged top plan view of the mount per se;

Figure 3 is a vertical sectional view on line 33 of Figure 2;

Figure 4 is a vertical sectional view on line 44 of Figure 2;

ice

Figure 5 is a transverse sectional view on line 5-5 of Figure 4; and

Figure 6 is a perspective view of the socket assembly of the mount.

Referring to the drawings in detail, the reference numeral 10 generally designates a conventional television antenna, 12 the antenna mount constituting the present invention, and 14 a pitched roof on which the antenna is to be erected.

The mount 12 constituting the present invention includes a relatively elongated, vertically extending, upwardly opening mast socket 16 closed at its lower end by a rectangular base plate 18 having a centrally disposed drain opening 20 and a series of corner openings 22. Spaced longitudinally of the socket 16 are set screws 24 threadable inwardly against the mast to firmly engage -the same in the socket, the set screws being provided with lock nuts 26 which are turned home against screw-receiving bosses formed upon the socket after the set screws have been clampably engaged against the mast.

Intermediate the opposite ends of the socket 16, but closer to the upper end than to the lower end, the diametrically opposed, angularly bent small ends of flat, downwardly divergent, approximately triangular leg attachment plates 30 are welded or otherwise fixedly secured. Two pairs of elongated legs 32 of L-shaped cross section are provided, the legs of each pair diverging in a downward direction and being connected by a single bolt 34 to the opposite sides of the associated attachment plate 30. As will be noted from Figures 1 and 2, the downwardly divergent side edges of the attachment plates 30 are engaged against the associated legs 32. The screws 34 are located at the lower corners of the attachment plates 30, and thus when the device is being assembled, the legs 32 may initially be swung together in par allel relation to facilitate carrying of the assembly, to the roof after which the legs 32 are swung outwardly to the positions thereof illustrated in the drawing, into engagement with the side edges of the associated attachment plates 30. This is of course at the users option, and one can instead assemble the device fully either on the ground or on the roof, wherever is more convenient.

Welded or otherwise fixedly securedto the respective legs 32, intermediate the opposite ends thereof are brace rods 36 extending radially and inwardly of the mount toward the brace plate 18, and having at their inner ends, depending, short extensions 38 engaged in the corner openings of the base plate. The rods 36 are inclined slightly from the horizontal as shown in Figure 4, downwardly in the direction of the base plate from their fixed connections to the legs 32.

Integrally formed upon the lower ends of the several legs 32 are short, depending, vertical extensions 40, connected to short feet 42 of right-angled cross section by I means of a single bolt 44. The bolt 44 provides a pivot about which the feet 42 can turn, thus to adjust the feet to any pitch of roof.

It will be apparent that the device is of such design as to permit it to be knocked down completely, preliminary to shipment and sale. This reduces measurably the cost of transportation, and at such time as the mount is to be placed in use, the several legs 32 can be swiftly assembled with the pipe socket, merely by connection of the bolts 34 to the attachment plates 30 and engagement of extensions 38 with base plate 18. When the mount is erected, of course, screws are extended through the base portions of the feet 42, with said feet adjusting themselves automatically to the pitch of the roof by reason of their being disposed transversely of the peak of the roof. The completely erected mount resists pressures effectively, so that the mast is firmly supported in such a position as to minimize to the fullest extent possible the danger of bending the mast or toppling thereof. This is achieved without the use of guy wires, since a substantial portion of the mast is engaged in the socket, with no loss of desired elevation of the antenna due to the elevation of the socket itself a substantial distance above the ridge peak.

It is believed apparent that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claim.

What is claimed is:

An antenna mount comprising: an elongated, tubular, vertically extending mast socket open at its upper end; a base plate closing the lower end of the socket, said plate including a marginal portion projecting laterally outwardly from the socket; means on the socket for clampably engaging an antenna therein; a pair of identical but opposite leg attachment plates fixed to the socket intermediate the ends of the socket, each plate having upwar'dly convergent side edges symmetrically arranged in respect to the length of the socket at opposite sides thereof, said plates lying in downwardly divergent planes symmetrically arranged in respect to the length of the socket at opposite sides thereof, corresponding side edges of the plates being in registration with each other transversely of the socket; pairs of legs, one for each plate, each pair being coplanar with its associated plate and the legs of each pair being respectively in longitudinal alignment with the respective side edges of their associated plate, the legs of each pair being pivotally connected intermediate their ends to their associated plate for swinging movement about axes normal to the plane of their associated plate and disposed symmetrically in respect to the socket at opposite sides thereof, each leg including a portion projecting across the plane of its associated plate for engaging a side edge of the plate on swinging movement of the leg in one direction to limit swinging of the legs in said direction; elongated brace rods rigid at one end with the respective legs and projecting radially of the socket from the legs, said marginal portion of the base plate having openings angularly spaced about the socket, the rods having extensions at their other ends removably engaged in said openings on swinging of the legs in said direction to positions in which said portions of the legs are in engagement with the side edges of their associated plates; and supportingsurface engaging feet on the several legs, formed as short bars pivoted on the lower ends of the legs for swinging movement about axes parallel to the pivot axes of the legs.
