A TTORNEYS United rates Patent COLLAPSIBLE ANTENNA Francis K. Saul, Sr.,Delhi, Ontario, Canada Application February 19, 1958, Serial No. 716,128 Claims priority, application Canada February 28, 1957 14 Claims. (Cl. 343-881) The invention relates to'an antenna of the type commonly used for reception of television signals and is particularly concerned with an antenna which can be collapsed for shipping purposes.
Prior to the invention several types of collapsible antennas have been developed which permitted shipping the antenna in a relatively small container. One type of known antenna structure which had the advantage of small shipping size also had the serious disadvantage that it must be assembled by use of nuts and bolts, so that the installer required a considerable length of time to erect the antenna. This gave rise to the need for an antenna using clamps to eliminate the use of nuts and bolts. Antenna structures were developed using spring clamps which permitted rapid unfolding of the antenna but it' was found that the spring clamps, because of the pressure which they exerted against the antenna elements as they were swung into position, caused scoring of the elements so that they were weakened, and in many cases it was found that the elements when subject to vibration such as that caused by wind broke at the points where they had been scored by the spring clamps.
The present invention provides a collapsible antenna having spring means permitting rapid erection of the antenna. According to the invention a channel-shaped member is closely fitted to each antenna element to protect it from scoring by the spring means during erection of the antenna. The antenna element is protected and reinforced at all times by the channel-shaped member in both the collapsed and erected positions of the antenna element.
The channel-shaped member is preferably of rectangular-shaped cross-section, and the spring means engages the channel-shaped member by a rectangular-shaped seat for the channel-shaped member so that the antenna element is held firmly and is reinforced against vibration or other stress. The various parts of an antenna assembly according to the invention are adapted to be riveted together thereby providing a more economical type of assembly. The antenna elements fold close to the antenna boom so that a minimum size of shipping carton is required.
The invention will be further described with reference to the accompanying drawings in which:
Figure 1 is an exploded view showing the various parts used in an assembly according to one embodiment of the invention;
Figure 2 is a perspective view of the parts shown in Figure 1 when assembled together; and
Figure 3 is a perspective view illustrating another embodiment of the invention.
The same reference designations will be used for similar parts shown in the three figures of the drawings.
Figures 1 and 2 show the assembly in accordance with the invention of antenna elements 14 to an antenna boom 10. The antenna boom is fitted with a crosswise channelshaped bridge member 11 which is cut out at 11a to fit the antenna boom 10. A spring member 12 is placed beneath the bridge member 11 and a bridge cap 15 is 2,926,350 Patented Feb. 23, 1950 placedabove the bridge member 11. A rivet 17 is used to fixthe bridge cap 15', the bridge 11 and the spring means 1210 the antenna boom 10.
Each antenna element 14 is fitted with a channelshaped reinforcing member 13 and is riveted through the bridge member 11- to the spring 12 by a rivet 16. The rivet 16 provides a pivotal engagement between the antenna element 14 and the bridge member 11, so that each antenna element 14 can be swung from a position parallel to' the antenna boom 10' to a position crosswise of the antenna boom 10 as indicated by the arrow in Figure 2. Each end of the spring member 12 is turned upwardly to form a rectangular shaped seat 12a for the channel reinforcing member 13. Sloping approaches are provided to cause the channel reinforcing member 13 to depress the spring 12 asthe antenna element 14 is swung into its position crosswise of the boom 10. When the channel reinforcing member 13 is in the seat 12a the spring 12 will snap up into its final position with the channel reinforcing member 13 securely held in the seat 12a. The antenna can be collapsed by depressing manually the springs 12 and swinging the antenna elements back against the antenna boom 10. A
Figure 3 shows a modification of an antenna structure in accordance with the invention. As shown in Figure 3 a bridge member 11 and reinforcing members 13 are used as in Figures 1 and 2 but the bridge cap 15 and the spring 12 of Figures 1 and 2 are eliminated by use of a combination spring and bridge cap 18. The bridge cap 18 is riveted by rivets 16 through the antenna elements 14 to the bridge 11. The bridge 11 is riveted to the boom 10 in the same manner as that shown in Figures 1 and 2. Because the combination spring and bridge cap 18 is on top of the assembly, the reinforcing members 13 are fitted on top of the antenna elements 14 to make engagement with the slots 18a in the bridge cap 18. Folding and unfolding of the antenna shown in Figure 3 is done in the same way as that of the antenna shown in Figures 1 and 2. The large hole 19 provided in the centre of the spring 18 is used to permit riveting of the assembled clamp to the boom 10 using a rivet 17 as in Figures 1 and 2.
The reinforcing channel 13 provided on each antenna element 14 plays an important part in supporting the elements 14 against vibration and preventing wear or scoring of each element 14 when it is swung into its position crosswise of the boom against the action of the spring 12. The reinforcing channels 13 transform the round elements 14 from a round cross-section to a rectangular cross-section so that they can be held firmly by the rectangular seats 12a of the spring 12. For shipping purposes, in order that the antennamay be placed in as small a carton as possible, the antenna elements 14 are folded to positions parallel to the boom 10 and, if there is more than one assembly of elements spaced along the boom 10, the elements 14 of adjacent assemblies can be folded to positions overlapping one another so that elements 14 from various assemblies lie side by side.
