(Cl. Z50- 33) -14 Claims. 1,

My present invention relates ,tov high vfrequency antennae .and more particularly .to a television receiver antennak so constructed and arranged-to `providemaxirnum elliciency in intercepting'radio frequencies -in the television spectrum and adapted to be-:readily set up from the collapsed [position ,to Athe fullyeerected ,position by.` simple .operations readily performable bythe 4unskilled user.

In television antennae adapted for use in connectionyvrith home type television receivers, it -iscustomary toA provide :some formof vertical :supporting structureisuch as almast, ahorizontal supportingstructure which is usually a metallic .crosserm secured to the mast, ran intercepting dipole which may be of ,thefolded' typesupported; at one endfof the cross farm and., insulated therefrom, Aand :a `reflecting dipole supported fat the other end of the :cross arm 4and vnot `necessarily. insulated therefrom.

lIn .thecase of: the folded.dipole,;the endsthere- Y of usually terminate at.;the cross arm 4where -appropriateconnectionsirnay be madeby lead-in Ywires -to, the `television receiver.

Various attemptshave been made to form these l1-,

ydipoles :and especially the mechanical. as well fas Athe `electrical connecting elements thereof Yin such manner that they. may vreadily z be, assembled Without the use of complex toolson the ,cross `ofthe mast. 1 .This has required, however, the utilizationof -nu'tsfand boltspassing throughregistering open.- lings:which-mustbelined up accurately in order to .permit assembly, tending to :make the .assembly `operation a factory .operation or lone which must be performed by a skilledxtelevision lerectorV or serviceman.

` Where .the connection was not propel-lyv unade for insecurely tightened, as frequently occurred yinthe case of erection of the television antenna by the home user, vibration ,caused by wind tended to loosen the antenna, therebycausing :tha-antenna itself` to wobble or vibratezin the vwind resulting. incinterference with; at least-video recentierr- YThis vVibrationwhen permitted to continue-l for any reasonable length of time tended also vto weaken and at times destroy the eifectiveoperatinsparts ofthe television antenna.

Where ,attempts havebeen made to connect =all parts of' the television antennadeavingthem,

lhotvever, inioldedcondition` for:y shipment and rstorage,;the friction or other; tightening elements -used;t o, secure the ,parts `in erected; unfolded condition werev subjected c to rotary-moments of; force on a rather long lever arm, especially :in the Ecase of a dipole-adapted for the-reception-.of the low frequency band television signals,A and :these antennae also. tended to collapse.

The object ofmy invention is :the prcmisionyof a quickly set up television antenna which without the utilization of special skill or any special `tools will permit a home user promptly and securely to connect the television dipoles to the cross arm of the mast: and this connecting setup may be made for both the main dipoles and the reflecting dipoles bythe most unskilled user within less than a minute.

Another object of my invention is to provide the dipole securing elements connectedor connectable to the cross arm of the television mast or to any other suitable supporting structure, the said connecting elements providing rigidifying elements for preventing relative movement of the dipoles with respect to the cross arm of the mast or other unit to which the dipoles are connected ;l frictionally secure positioning means which are not subject to any rotative moments of force and which can be released lonly by movement of the dipole elements in a direction which would not occur during the actual use of the antenna; and additional securing means rmly locking the antenna structure and especially the dipoles thereof in place.

Essentially, my invention contemplates the .provision of a securing or connecting member with simplied means for mounting the same on a cross arm of the antenna mast or other appropriate antenna support.

The connecting member is channel-shaped having a longitudinal axis extending parallel to the axis of the dipole. The inner end of the dipole is shaped to fit into the longitudinal connecting member. The vconnecting member and the dipole are so shaped that when the dipole is inserted longitudinally it is wedged in the connecting member by this longitudinal movement, the frictional engaging surfaces extending `substantially parallel to the axis of the dipole and the frictional Wedging force being directed at a substantial angle to the axis of the dipole.

Consequently, the only way in which the dipole may be loosened from its connecting member ris by an outward pull parallel to the axis of the dipole. Wind vibration or other forces which may cause the dipole to vibrate have a component in a direction extending at some angle to the axis `of the dipole and usually at right angles thereto.

Consequently, such vibrational forces would not have a loosening eect on the dipole. In addition, the inner end of thea-dipole has a longitudinal slot preferably extending parallel to vthe axis of the dipole and engageable under the head of a bolt carried by the connectingmember, the bolt being preferably provided with a wing nut and a lock washer to tighten the bolt down on the end of the dipole.

Thus, in connecting a dipole end to myvnovel connecting member, the end of the dipole need merely be slid into the end of thel connector and pushed tightly therein so that the end of the slot moves under the head of the bolt on the connector; the wing nut is then tightened.

Therefore, each dipole end requires two simple operations for connection: (l) an inward push into the connector as far as it will go, and (2) the tightening of the wing nut. Each such operation requires but a few seconds so that an entire antenna interceptor and reflector structure may be assembled even by the unskilled user within less than a minute.

The mechanical connector for the dipole may be provided with an additional opening preferably adjacent the end thereof opposite that into which the dipole is inserted through which a bolt may be passed for connection to a lead-in wire; so that the only other operation required after erection of the antenna is to connect the lead-in wire to this bolt, on each side of the dipole.

My invention may take many forms, but its essential element is the provision of means for Wedging the dipole end in position by longitudinal movement combined with a simple operable securing means; and further combined, if desired,

With simplified means on the connecting element itself for connection to a lead-in wire.

The foregoing and many other objects of my invention will become apparent in the following description and drawings in which:

Figure 1 is a view in perspective showing my novel antenna structure.

Figure 2 is an exploded view in perspective showing my novel connector structure.

Figure 3 is a top plan View of the connector of Figures 1 and 2.

Figure 4 is a side view of the connectors of Figures 1, 2, and 3.

Figure 5 is a View in perspective showing a modified form of the connector of Figures 1 to 4.

Referring first to Figure l, a vertical mast I carries secured thereto cross arm II which preferably is a tubular metallic cross arm in order to obtain sufcient structural strength.

The cross arm II carries clamping channel I2 having the V-shaped notches I3, I3 which are aligned vertically to engage the mast I0. A U- shaped bolt I4 is arranged to surround the mast I0, the legs of the U-shaped bolt I4 passing through openings I in the cross arm II and through similarly aligned openings in the chan- U-shaped bolt I4 toward the base of the channel I2 making a clear space between V-shaped notches I3 and the bend of the U I4 smaller until the mast IIJ is tightly clamped.

This particular securing or integrating member for connecting the cross arm II to the mast I0 forms no part of my present invention but is described and shown herein only for the sake of completeness. Any suitable means may be used to obtain this interconnection between the cross arm II and the mast I0.

The ends of the cross arm II are collapsed at 20, 2| to provide a flat surface on which the interceptor dipole and the reflector dipole may be mounted.

In Figure 1 there is shown a folded dipole for interception of the high frequency waves. The folded dipole comprises the pair of

metallic tubes

26, 21 bent into a U-shape and collapsed, respectively, at their ends 28, 29 and 30, 3|.

The ends 28 and 29 of the U-shaped section 26 and the ends 3U, 3| of the U-shaped section 21 are collapsed in such manner as to produce a relatively flat center 35 and longitudinally extending lateral'ribs 36, 31. (See also Figures 2 and 4.)

The tube end 28 illustrated in Figures 2 and 4 and the other tube ends as well are also so collapsed as to produce the chamfered connection 40 at each side between the body of the tube and the lateral longitudinally extending ribs 36, 31.

The end of the tube at the flat section 35 ls provided in each case with the longitudinally extending slot 42 communicating with the end of the tube and open thereat. Each of the connecting elements 45 is provided with a pair of parallel side walls 46, 41 extending substantially parallel to the axis of the connector and substantially parallel to the axis of the tube to be inserted therein.

However, the walls 46 and 41 taper toward each other so that the space between them at end 48 of the connector is narrower than the space between them at end 55 of the connector. The ribs 36, 31 at the end 28 of the tube are spaced apart so that their outer transverse dimension is less than the distance between the parallel Walls 46, 41 of the connector 45 at end 50 but is greater than the distance between the walls 46, 41 at end 48.

As a matter of fact, the walls 46, 41 taper together quite close to the end 50 to a degree where they will tightly engage the ribs 36, 31.

The ribs 36, 31 of the tube end 28 in essence form an I beam with the tube section 35 and are substantially incompressible.

The walls 46, 41 of the connector 45 are of relatively strong metal; but are sufficiently resilient so that they may be resiliently spread by the insertion of the tube end 28 therebetween with sufficient force and owing to their resilience will frictionally engage tightly against the sides of ribs 36 and 31.

In addition, the connector 45 is provided with the bent-up Wall 52 adjacent the end 5D, the said Wall 52 having the horizontal slot 53 to permit passage thereinto of the flat section 35 of end 28 of tube 26, the tube 26 being taken by way of example and being representative of the other tubes.

Communicating with the flat horizontal slot 53 are the vertical slots 54, 54 in the bent-up wall 52. These vertical slots 54 are dimensioned so that they will readily receive the ribs 36 and 31 and permit the entire unit thereby to be inserted into the connector 45.

They are, however, so dimensioned that the chamfered portions 40 of the ribs 36 and 31 which connect them with the tube 26 can slide in only part way before engaging in tight frictional engagement with the material defining the vertical slots 54, 54.

The force necessary to push the tube end home in the connector will result in a slight deformation of the portion of the wall 52 defining the slots 54 as they are forced up onto the chamfered portions 40 of the tube 26. This deformation is also a resilient one creating a line frictional engagement at substantial pressure which serves to anchor the tube in place.

As the tube end 28 is pushed home, the slot 42 moves under the head of bolt 60 which passes through opening 6I. Bolt 60 may be tightened in place by the wing nut 62. and an appropriate vby the bolt66 and the nut 61. through opening 6| of the connector and aligned "gagsevgsvv ldckwasher'may be used. This serves mechani- `'callytoanchor the tube en'd in'place.

By this means, therefore, any lateral vibrat.

ing force transverse to the axis. of tube 26 will have no component of force tending to loosen vibrating force to which the tube may reasonably be subjectedwill 'have a component in that direction. In vadditionthe bolt 60 rand wing nut 62.provide. a secure mechanical arrangement.

Thus, Ain order to anchor the tube 26 in the connector, it is necessary only to insert the flat- -tened end thereof through the composite slot 54,

Since the connector is metallic, it may be made-of suitably conductive material and provide'an appropriate means of securement for a `lead-in wire. This means of securement for the lead-in wire is providedvat end 48 of the connector by the opening 65, the bolt 66 passing through the opening and the nut 61 which provide a means for securing the terminal lug of the lead-in wire or the lead-in wire itself to the end 48 of the connector 45.

` While Figures 1 vto 4 show the preferred form -of my novel connector, it will be obvious that it may'assume many other shapes within the principles of my invention.

Thus, in Figure 5 I have shown a modiedform of connector |45 having the opening |6| to receive a bolt and wing nut assembly similar to -the bolt and Wingnut assembly 62 of Figure 2.

Instead of the parallel walls 46, 41 and the end Wall 52 of the connector of Figure 2, I provide curled-over channel members l 46, |41 in the These will receive the ribs36, 31 of the end 28 of tube 26, the chamfered por- Vtion of the tube pressing into the

edges

200, 200

ofthe connector |45 When'the'tube is pushed home.

Here again the channels |46 and 141 may be tapered'toward each other to provide a tight 'frictional resilient engagement'of the ribs 36 V and 31 in connection with the frictional engagement of the ends 200 of channels |46 and |41 on the chamfered surfaces 49 of the tube.

'The other operations, aswell as the advantages of the unit of Figure 5, are substantially the same as those previously described in connection with the unit of Figures=l to 4.

In iFigures l and 2I have shown apreferred "manner in which the connector maybe embodied commercially for use in connection with the antenna structure.

An insulating plate or bracket 90 is providedV with longitudinally aligned openings 9|, 92, 91a, 92a. A connector 45 is secured to the pair of openings 9|92, and another connector 45 reversed 180 is secured to the aligned openings Bolt 66 passes through opening 92 of the insulating bracket 90 and opening 65 of the connector 45, the connector being, therefore, held in place Bolt 60 passes opening 9| ofthe; insulating .bracket-90 where 'it is held in placeby the Wingnut 62.

Wing nut 62 need not be .removed from the bolt 60 in ordertoprovide for securementof the antenna thereto .as `previously described since the slot 42 simply 4slides under .thehead of `bolt Bolt 66 need. notbe removed completelybut need merely be loosened in order toV provide, .for the insertion under the head thereof of anantenna 1ead-in connector clip or of a turn or two of the. lead-in wire itself.

Where the connector clip is a full annular'tclip, then, of course, the bolt 66 must be temporarily removed to slide the clip over the same. The

connection of the lead-in wire may, if desired,

be made at the factory for standard lengths since the lead-in wire may readily be coiled up and `.will not interfere with the arrangementl ofthe antenna structure in a small package for shipment. v

The antenna parts, however, are. disconnected during shipment and are-inserted in position-b the simple method vpreviously described.

The insulating plate or bracket is also provided with Va pair of Atransversely aligned openings 95, 96 for securement to the collapsed end'20 of cross arm that is, a pair of bolts 91,98 are passed through openings 96, and appropriately spaced openings in the collapsed end 20 of cross arm l and are held in place by nuts.

Thus, where a straight dipole is used, the only operation required in assembly is to pass'the bolts 91,98 through op'enings'96, 95 .and then .through the aligned openings in the collapsed end-20 of cross arm and zsecure them'in place by nuts. The two dipoles are .then forced into the opposite connectors 45 and secured `in position as previously described.

This is also true in the case of a folded dipole,

lthe ends of the dipole being sufficiently 'flexible and the relative amount of movement being such as to permit this kind of connection to be made.

Where, however, the 'folded dipole is-too rigid to permit this to be done or where the Vfolded dipole is a large one for use'primarily on relatively low frequencies, then the folded dipole is shipped in two

parts

26, 21 each bent in U-shapedform as shown in Figure 1.

In this case, a U-shape'd bracket |00 is secured to the top of the insulating bracket 60 (on'the side opposite the securement of bracket 92 on the cross arm Il so that bracket |00 will be insulated therefrom) by the bolts 91, 98.

The two ends 28, 29 of theU-shaped tube 26 are pushed in simultaneously in the upper and lower` brackets onthe right side rof Figure land the two ends` 30 Aand 3| of the' U-shaped tube'21 are'pushed in simultaneously in the upper and

lower connectors

45, 45 on the left side of Figure 1. The metallic strip |90 serves, to completethe folded dipole at its upper leg.

The base of the bracket |00 is, of course, spaced from the inner ends of the lower connectors:l 45, 45'so that the dipole is not short circuited.

The reflecting antenna 225 comprises a pair of tubes 226, 221 shaped at theirv inner ends 23|, 229 to correspond exactly with the shape shown for the tube 26 of Figure 2. The connectors 45 are mounted on a rear metallic plate 299 secured to the. collapsed rear end 2| of. the cross arm. Il

by the bolts 25|, 292 passing through appropriate openings in the collapsed end 2| of the cross arm and being held in place by appropriate nuts.

An insulating bracket similar to the bracket 90 may be used, where desired, but for utilization as a reilecting antenna it is preferred that the reector 225 be a single cross bar electrically in engagement with the cross arm and the lmast I0.

the antenna will be the home user himself, then preferably the cross arm has secured thereto the insulating bracket 90, the bracket |00, and the Abracket |90 at the front end and at the opposite end the bracket 290 together with the six connectors normally carried thereby.

Since the bracket 90 need be no more than of the order of six inches long, the maximum Width of the package in one plane need be no more than six inches and the other elements of the antenna, of course, may be appropriately nested in the package.

Where the package is to be flattened to say a maximum width of one inch, then, of course, brackets 90, |90, and 290 mut be disconnected from the cross arm.

When, however, the home user receives the cross arm with the brackets thereon, the only operation he must perform is to push the ends of the dipoles into the connectors and tighten the wing nuts.

If the lead-in Wire has not already been connected to bolts 66, then, of course, they should be connected to these bolts or they may even be connected under the wing nuts to bolts 5G where required.

Thus, to connect the dipoles to the cross arm the only operation that need be performed is the single longitudinal movement of each dipole into its connector and the tightening of the wing nut.

This is the essence of my invention.

In addition, the simplified means provided for connecting the lead-in wire makes such a connection obvious and easily performed.

The connectors may be delivered mounted on their appropriate brackets so that where the brackets must be disconnected from the cross arm to facilitate shipment it is only necessary to pass a pail` of bolts through aligned openings of the bracket and the cross arm to connect the bracket to the cross arm.

By this means, therefore, an antenna structure is provided which may be readily and quickly erected and locked in position which is mechanically strong enough to survive weathering and wind forces and which will not be disrupted by vibrational forces.

In the foregoing I have described my invention solely in connection with specific illustrative embodiments thereof. Since many variations and modifications of my invention will now be obvious to those skilled in the art, I prefer to be bound not by the specific disclosures herein contained but only by the appended claims.
