f: IOP INVENTOR. Dona/d LB/esec/rer United States Patent 3,182,329 ANTENNA MOUNTING CLIP Donald L. Biesecker, Dayton, Ohio, assignor to Illinois Tool Works Inc, Chicago, 11]., a corporation of Delaware Filed June 13, 1963, Ser. No. 287,542 14 Claims. (Cl. 343-702) This is a continuation in-part of my co-pending application Serial No. 157,655, filed December 7, 1961, which is now abandoned.

This invention relates in general to antenna assemblies for electronic equipment and more particularly relates to means for mounting an antenna assembly in electronic equipment such as television equipment and the like.

In certain types of television equipment, for example, it is desirable to provide integral antenna means. This is particularly desirable among so-called portable television sets and other types of portable electronic equipment such as portable transmitters, portable short-wave radios, portable walkie-talkies and similar types of equipment. Sets of electronic equipment which must be moved from one location to another have need for integral antennas where it is inconvenient to provide a multiplicity of outlets for permanent full size antenna installations. As a compromise from an electronic standpoint, the television industry has, for example, developed the use of a pair of tubular elements commonly known as rabbit ears" which, when oriented in a directional relations-hip to the television transmitter, will receive quite effectively the transmitted signals. It is usual, in the art, to provide a ball and socket joint so that the tubular members associated therewith can be svviveled in all directions to assume an attitude and direction most desirable for the reception of the transmitted signal. Heretofore, very complex assemblies have been utilized to assure a bias against the ball and socket joint so that the tubular members are maintained in their desired final position. Further, the assemblies are made even more complex when it is desired to telescope the antenna tubular members within the casing so that they are protected against accidental damage when they are not in use.

It is an object or this invention to provide a simplified assembly of the aforenoted type for use with portable electronic equipment and the like.

More particularly, it is an object of this invention to provide a ball and socket joint which maybe readily assembled to the electronic equipment, which will maintain a permanent bias on the ball so as to retain the ball and its associated elements in a variable fixed attitude while affording telescopic movement of the tubular members through the assembly.

Still another object of this invention is to provide a clip means having a pair of substantially parallel leg portions with connection means therebetween, both of the legs being .apertured and the margin of the aperture in at least one of the legs directly supporting the ball, the other leg through the connection means imparting a bias to the ball by the mounting thereof to a portion of the electronic equipment.

Still another object of the invention is to provide a clip means of the aforenoted general characteristics which has electrical connection means integral therewith, the clip means being made of resilient metal, for atfording a direct electrical connection from the antenna means to the electronic apparatus as suitable and desired.

The novel features which are characteristic of the invention are set forth with particularity in the appended claims. The invention itself, both as to its organization and its method of operation, together with additional objects and advantages thereof will best be understood by 3,182,329 Patented May 4, 1965 the following description of specific embodiments when read in connection with the accompanying drawings in which:

FIGS. 2628 are views of still another embodiment of clip means and its assembly.

Portable electronic equipment such as, for example, the portable television set shown in FIG. 2 requires the use of an integral antenna means. To prevent accident to the antenna means during transporting of the equipment, it is preferable that the antenna be mounted so as to be located substantially within the outer housing means 6. On the other hand, when the equipment is in use in different locations, it requires that the antenna means be elevated and located at different attitudes relative to the set. Various assemblies shall now be discussed which provide these functions in an economical manner.

All of the clip means assemblies 8, about to be discussed, utilize the housing means to mount fastening means, or

provide the fastening integral therewith by various abutments which allow a wedging of the clip means 19 interiorly of the housing to provide the requisites resilient bias upon the assembly while affording telescopic movement therethrough. V V

Returning now to FIGS. 1 through 6 of the drawings, the clip means 10 is shown'in an assembly 8 in'FIGS. 4 and 5 of the drawings. FIGURES 4 and 5 of the drawings represent sectional views through the housing means 6 of a television set shown in FIG. 2 of the drawings. The clip means 1ft is generally J-shaped in configuration and has a body defined by an upper plate or leg 12 and a lower leg or plate 14 which are normally substantially parallel to one another and interconnected by a connection means in the form of a'bight portion--16 integral therewith. The upper leg 12 is apertured as at 18 and 26 respectively. Surrounding aperture 18 is a flange 22 having, in section, a substantially spherical conformation, for purposes best set forth hereinafter, which extends upward- 1y away from leg 12. Flange 22 can if desired be frustoconical as shown in FIG. 8A at 22 rather than spherical. Flange 22' has a diameter at 21 less than dimension Zr and a diameter at 23 greater than dimension 2r so that a point of tangency t is established intermediate the height of flange 22. The material surrounding aperture 2% is distorted to provide stud engaging means which is a stamped helix for accepting a screw thread.

The lower leg 14 is normally longer in length than leg 12 and is provided intermediate its length with an aperture 24. At a point just beyond aperture 24 and adjacent the terminal end of leg 12, leg 14 may be bent upwardly at substantially right angles thereto to form strut 26 and thence is bent outwardly again to provide a lateral extension 28 to its free end. Intermediate the strut 26 and the free end 28 there is provided an aperture 3% similar to aperture 20 in that it has stud engaging means encircling said aperture. Strut 26 is of such a length as to place the lateral extension 28 in substantially the same plane as leg 12.

Aperture 24- is surrounded by a downwardly and inwardly extending flange 32 having in section a substantially spherical confrontation of a radius similar to flange 22. In this embodiment flange 32 is reversely bent outwardly to provide a funnel-shaped skirt 34 which at its juncture with the flange 32 forms a passageway 36 of a predetermined diameter, for purposes best set forth hereinafter.

As best seen in FIG. 6, leg 14 and bight 16 are slotted as at 44) to provide a clearance hole in leg 14, for acceptance of a screw as later described, and to reduce the amount of material in bight 16 so as to control the resiliency of bight 16.

A tab 44 is struck from the material of leg 14 and bent downwardly in the same direction as flange 32. Tab 44 is designed to be used as an electrical connector. Inthe present instance, it is of the so-called spade type configuration although other forms of electrical connection can be made to the clip body.

Clip is preferably a heat treatable sheet metal clip made from strip material of a constant width for economy in fabrication. This product has the characteristics of high strength and continued resiliency.

The antenna utilized in portable television sets includes a ball 48, which is technically a segmented sphere of two bases, having a through bore and a collar 50 surrounding said bore at its upper end. Telescopically associated with ball 48 are a plurality of thin wall tubular members 52 which are capable of co-axially internesting inside one another. The outer tube 52 is provided at its lower end with a flange or bead 54 and at its upper end with a beaded flange 56. The diameter of the

beads

54 and 56 is controlled so as to limit the axial movement of the tubular members 52 within ball 48. At the upper end there is preferably a second beaded flange 58 which provides tubular means

intermediate beads

56 and 58 for grasping the outer tube to move same to extended position beyond the case.

The ball and tube subassembly can be preassembled to the clip prior to installation in the case. This is most easily accomplished by springing

legs

12 and 14 outwardly in opposite directions, inserting tubes 52 through aperture 18 and snapping ball 48 into the socket 66 formed by

opposed flanges

22 and 32. Clip means 10, can for ease of assembly of ball 48, be initially formed with

legs

12 and 14 disposed in a spread apart or diverging position, without impairing the function of the clip.

it is also possible to provide a clip means, of the type shown in FIG. 9, wherein the upper leg 12 and flange 18 are slotted from an edge as at 90 to assist in the preassembly of the ball and tubular members with the socket. In this modification the

legs

12 and 14 are spread apart so as to accept the ball; the tubular members are then pivoted through slot 90 into assembled position.

Referring back now to clip means 10, the radii of curvature of

flanges

22 and 32 are substantially identical to the radius of curvature of ball 48, or preferably are conical V as shown in FIG. 8A. In the embodiment shown in FIG.

1, while these

radii

62 and 64 as indicated by the arrows are on the common center line or axis of

opertures

18 and 24, their centers are axially displaced relatively to one another. The center of radius 62 for flange 22 is positioned below the center of radius 64 for flange 32, for purposes best set forth hereinafter. It should be noted, however, as indicated hereinabove, that while this embodiment of the present invention utilizes spherically disposed flanges to form the socket means, other means can be used and will bediscussed hereinafter.

For the application of the clip 10 to the housing means 6 of a television set, the upper wall of the case 7 6 may be provided with a plurality of apertures suitable for the mounting of two assemblies 8 of clip, ball and tubes, but in the present instance we will only discuss a single application since they are identical. (Also, it will be noted that some sets only use one antenna.) A central aperture '72 is provided in case 7%) and on opposite sides thereof a 'pair of

smaller apertures

74 and 76 respectively are also provided. The clip and ball assembly are positioned with leg 12 resting against the inside surface of case 79 and with flange 22 projecting upwardly into aperture 72, serving as a locating means for accurate positioning of the clip. Leg 12 is dimensioned to traverse both sides of aperture 72 and prevent removal of the clip through aperture 72. A pair of screws '78 and 80 are telescoped through apertures 74 and '76 into engagement with thread engaging means 2% and 30, respectively. Screw 78 draws leg 12 into intimate contact with the inner surface of case 7tl. Screw 8t) draws the lateral extension 28 into intimate contact with the inner surface of the housing or case 70. It will be appreciated that when ball 48 is positioned in the socket 6t) during preassembly the distended relationship of the radii of

curvature

62 and 64 tends to spread the clip apart from the preferred initial substantially parallel relationship of legs 12 and '14. When screw 30 draws lateral extension 28 into engagement with the undersurface of case 70, this bows leg 14 and because of the resilient nature of the material of the clip impresses a spring bias against the surface of ball 48. The amount of this bias, as a result of the bowing, is predetermined by the length of strut 26. This bias continues throughout all angular positions of ball 48 relative to the socket 60. The ball and tube subassembly can be tilted within limits of the contact of collar 50 with the upper surface of flange 22, as shown in phantom in FIG. 4.

Referring now to FIGS. 4 and 5, the diameter of beaded .flange 54 and the outer tubular member 52 are controlled relative to passageway 36 so that the internested tubes 52 can be axially pressed downwardly in internested relation to be enclosed within case 70. The lateral movement, of

the tubes 52 in this lowered position, is limited by the controlled diameters of the tubes 52 relative to passageway 36, when taken in conjunction with the center of movement of ball 48. This limited lateral motion as best seen in phantom in FIG. 15 prevents contact of the tubular antenna elements with any of the electronic circuitry internally contained within case 71}.

The funnel-shaped skirt 34 has a two fold function, first, it provides a pilot or guide means for feeding flange 54 up within socket on so that the subassembly of ball and tubes can be fully extended and swiveling thereof permitted. Secondarily, it has been found desirable in certain applications to provide a dielectric tube 80 for encapsulating tubes 52 in their lowered or retracted position as an added safety feature. Suitable spring securing means 82 encircles the outside surface of the juncture of

flanges

32 and 34 and retains the end of tube 80 in the concavity therebetween.

A modification of the present invention is shown in FIG. 7 wherein similar numerals are utilized to designate similar parts with the addition of the suflix a. In certain case designs it is desirable to retract the tubes 52 at an angle other than perpendicular relative to the surface of case 70, hence, in this embodiment the passageway 35a is angularly disposed relative to the axis of flanged aperture 18a. All of the other features of the clip such as the disposition of legs 12a and 14a and flanges 22a and 32a are substantially identical.

The third modification shown in FIG. 8 relates to a similar device wherein similar parts are designated by similar numerals with the addition of the sufix b. In the first embodiment the radii of

curvature

52 and 64 had centers axially displaced along the common center line. In the

present embodiment flanges

22b and 32b have a common radius of curvature 84 on a common center. In this embodiment, strut 26b is made shorter than strut 26 of the other embodiments. When extension 28b and its threaded aperture 39b are drawn into engagement with the under surface of the case, leg 14b will bow and produce the desired spring bias against a ball, not shown, having a radius of curvature complementary to radius 84.

In all of the embodiments suitable connection means 86, shown in phantom for purposes of illustration, are attached to terminal 44 for electrically interconnecting the tubular antenna members 52 through the ball 48 and clip to the electronic circuitry of the set.

Referring now to FIGS. 10 and 11 wherein similar parts are designated by similar numerals with the addition of suflixes c and d respectively, FIG. 10 is basically identical to the first embodiment with the exception that aperture 180, instead of being surrounded by a spherical or conical flange, is provided with a reversely bent flange portion 92. Flange 92 presents a smooth interior surface 94 and is totally adequate as a bearing surface for a ball of the type previously described. In addition, the terminal 440 in this embodiment has been moved from the central portion to the left extremity as viewed in the drawing and depends from the bight portion 16c. Similar to the first embodiment, it is struck from the material forming leg 140.

The embodiment set forth in FIG. 11 shows a modification to the lower flange $20!. A plurality of protuberances extend inwardly from the inner surface of flange 32d. Ball 48d is provided with a plurality of annular grooves 98 axially spaced about ball 48d. The grooves 98 cooperate with protuberance means 96 to permit ball 48d and associated tubular elements 52d to be ratcheted in angular increments within the socket member.

FIGS. 12 through 14 disclose various forms of alternate fastening means wherein similar parts shall be designated by similar numerals with the addition of the suflixes e, f and g respectively. In FIG. 12 the fastening means such as screw 78 and thread engaging means 2%, of the first embodiment, are replaced by a hook shaped means 100. Hook 1% is struck from the confines of leg 12e. In assembling this clip with the case, hook 109 is telescoped through aperture 74:; and the entire clip assembly is then slid to the right, as seen in the drawing, to engage the upper surface of case Ytle. Screw Stle is then passed through bore 76c into engagement with thread means 302 and drawn upwardly to fasten the assembly to the case.

FIG. 13 discloses an embodiment similar to that shown in FIG. 12 with the exception that a hook means 102 is provided at the extremity of leg 14- with the resultant elimination of the screw 86 and thread locking means 30 of the first embodiment. In this instance hook 1tl2 is fed through bore 76 until it is overriding the upper surface of case 711 Then screw 78 is telescoped through bore '74- into engagement with nut means 29 In both of the embodiments shown in FIGS. 12 and 13, the remaining portions of the clip are substantially identical to the first embodiment.

While all of the previous embodiments show the clip as having a substantially J-shaped con-figuration, it must be appreciated that the choice of this shape is primarily for economy of materials. However, it has been found that certain advantages accrue when the upper leg 12g, as seen in FIG. 14, is made of a length substantially equal to lower leg 14g and provided with a pass-through aperture 194 to accommodate the telescopic assembly of screw 80g with threaded means 30g. This provides an assembly with more positive control over the location of the ball retaining flanges and affords a wider range of tolerances in the casing aperture 72g. It will also be noted that strut 26g is at an angle other than in this embodiment. Also to be noted is the frusto-conical shape of flanges 22g and 60g which accommodate to a wider range of tolerances in the balls 48g.

It should be noted, of course, that it is most desirable that the case 70 used with this sheet metal clip means be fabricated of a dielectric or plastic material. Should the case 70, of necessity, be metallic in nature, then it would be necessary to interpose a dielectric material between the clip and the case to prevent a short circuit or grounding of the antenna.

To facilitate the insulation of the clip means from a metallic case, we refer now to FIGS. 15 through 17 wherein similar parts are designated by similar numerals with the addition of the suflix 11. FIG. 15 is a perspective view of a plastic or dielectric spacer mounting means 108. Means 1% is a generally planer member having a large central aperture surrounded by an upstanding flange 112. A pair of smaller apertures 114 are provided on opposite sides of aperture 110 and each has an upstanding flange 116 extending in the same direction as flange 112. Each of said flanges 116 are countersunk at their outer extremity as at 118 for purposes best set forth hereinafter.

Spacer means 108 can be preassembled to clip means ltlh by telescoped aperture 110 over the extremity of tubular members 52g and the outer flange 22h of the clip. A pair of oval head screws 119 are mated with their respective thread means to assemble a spacer means 108 with the preassembled clip and antenna. The entire assembly is then telescoped into a metallic case 120 having

mating apertures

122, 124 and 126. The flange 112 projects internally of aperture 124 while flanges 116 project beyond the limits of

apertures

122 and 126 respectively to position the entire assembly relative to the case. By tightening screws 119 their heads will radially deform flange 116 so as to overlie the upper surface of metallic case 121 Thus, in this embodiment applicant has provided means for insulating the clip 10 from the metallic case 120 and also has made provision for an economical mode of assembly.

Another embodiment of the invention is shown in FIG. 18 which is similar in many respects to that shown in FIG. 12 and similar parts will be identified by similar reference numerals with the addition of the suflix i. In this embodiment the portion of the upper leg shown to the right of the aperture 18 has a little more stock and the corresponding portion on the lower leg, instead of being through apertured to receive a screw, is offset downwardly for engagement with an integral molded abutment 127 of the casing. In assembly the clip means 19 the two free ends of the upper and lower arms are inserted between the upper portion of the housing 70 and the boss 127 and slid to the right as viewed in FIG. 18 so as to affordthe positioning of the hook 1601' over the margin surrounding the aperture 74 It will be seen that this embodiment does not require auxiliary fastening means, relying instead upon the boss 12'? to provide a reaction member against which the lower leg will impart a bias to the ball 48 through the connection means bight portion 16 The assembly 8k shown in FIG. 19 is similar in many respects to that shown in FIG. 18 and similar parts Will be identified with similar reference numerals with the addition of the sufiix k. The assembly 8k utilizes two

abutments

127k and 129 which are spaced apart to provide an internal housing aperture 131 for affording the telescopic movement of the antenna 52 therein. This type of mounting arrangement, i.e. with the use of no screws with the clip means ltik as shown, requires that the aperture 72k be located relatively close to an edge surface of the housing. 7

The assembly 81 shown in FIG. 20 is substantially similar to the foregoing and similar parts will be identified with similar reference numerals with the addition of the suffix l. The clip means rather than being J-shaped or U-shaped, is S-Shaped in configuration. It is mounted by a wedging action rather than by auxiliary fastening means. The upper leg ml is not as long as that shown in the foregoing embodiments and the middle leg 128, intermediate the upper leg and the lower leg 141 provides the flange 68! for ball 48L Electric terminal tab 441 is struck from bight 130 connecting legs 128 and 14L It will be noted that apertures 13] and 241 and 132 are coaxial when the clip means ltll is in assembled position. The lower leg 141 of the clip means It)! is formed with downturned tabs 134 adjacent the free end thereof to prevent outward movement of the clip means or the assembly once it has been placed in position as shown in FIG. 20. The leg 14l engaging the margin surrounding the aperture 1311 of the casing imparts a bias through the bight portion 130 to the lower portion of the ball and through bight portion 161 to the upper portion of the ball to provide a resilient bias against the ball 14!. The clip is assembled by placing the assembly into the aperture from right to left as viewed in FIG. 20, the electrical terminal tab 441 being positioned for easy access thereto for connection to the circuit as aforedescribed.

The assembly shown in FIGS. 21 and 23 utilizes the clip means 10m shown in FIG. 22. Similar parts will be identified with similar reference numerals together with the addition of the suflix m. The assembly 8m is quite similar to that shown in FIG. except that it is two piece in that the upper leg is replaced by a collar 136 which is separate from the remainder of the clip means. The collar has a flange which engages the margin of the casing surrounding the aperture 72m in the casing. A ball retaining flange is formed similarly to those formed normally in the upper leg of the clip means heretofore described. As can be seen in FIGURE 22, the lower portion of the clip means 10m has a leg 128m providing the lower ball flange 60m which is connected 7 to the lower leg 14m by a bight portion 13tlm. The lower leg is bifurcated to the left of the aperture 132m and the tabs 134m are struck out of portion of the margin of the aperture 132m as best shown in FIGS. 22 and 23. The tab for electrical connection means 44m is struck out of the bight portion 139m. The bifurcation of the lower leg 14m affords slightly easier springing of the assembly 8m between the

bosses

127m and 129m duringinitial assembly. The confronting side edges of the bifurcated lower leg 14m may be formed with tabs'137 for purposes about to be described.

The assembly 811 is substantially identical to the assembly shown in FIGS. 21-23 with the addition of the assembly member 138 and similar parts will be identified with similar reference numerals with the addition of the suffix n. The antenna guide means 138 essentially comprises a flared hollow member having a groove means 146 at the lower end which'is merely inserted between the bifurcated legs of the lower leg 14. of the clip means. The tabs 137 of the clip means retain the member 138 in a coaxial position with the antenna and member 138 has a height sufiicient to guide the lower end of the antenna within the housing. In all other respects the assembly 811 is identical to assembly 8m. It will be noted, as shown in FIG. 25, that the member 138 is initially not coaxially aligned with the aperture flange 61in but it becomes coaxial therewith after assembly as shown in FIG. 24.

The assembly 8p shown in FIG. 28 and the clip means 10p shown in FIGS. 26 and 27 have many similarities to the foregoing embodiments and similar parts will be identified with similar reference numerals with the addition of the sufiix p. In this embodiment, the clip means ltlp is Z- shaped in configuration, the upper leg 128p corresponding to 1281i and 128m of the embodiments shown in FIG. 25. The middle leg 14p and the lower leg are shown in stressed position in the assembly 8p shown in FIG. 28, each being apertured at 132p and 142 respectively. In essence the bight portion p immediately above the tab 44p is a shortened version of bight 130m and an additional bight portion 146 is provided between the lower leg 144 and middle leg to impart the resilient bias against the ball. To facilitate assembly of the clip in the assembly hp, the upper leg 128p is provided with a shallow curvilinear groove 148 adjacent the free end thereof as best shown in FIGS. 26 and 28. The free end 134p of the lower leg 144 is turned downwardly to prevent accidental withdrawal of the clip means.

As can be seen from all of the embodiments in the invention, it is contemplated that simple stamping means in the form of various types of clip means are mounted to the casing by fastening means in the form of bolts or screws or a simple wedging action is used in conjunction with utilization of bosses or abutments within the television casing. In all embodiments of the assemblies shown, coaxial bore means are provided in the legs of the clip means to accept a plurality of the tubular extensible members which are telescopable within the housing. Also at least the margin surroundingbore means in one of the leg means of the clip means directly supports the ball for limited swivel movement thereon, the construction being of the type wherein another leg of the clip means is mounted to the housing so as to impart through a connection portion to another portion of the clip means, a resilient bias to supply resilient pressure on the swivel ball without disabling the telescopic movement of the antenna therethrough. Also all of the clip means have electrical connection means integral therewith to provide an electrical connection through the clip means to the swivel ball and thus to the antenna members.

The assembly provides a constant predetermined amount of spring bias for effectual operation and use of antenna means, no readjustment being necessary by the purchaser. Fatigue of parts, as experienced in other antenna assemblies, is virtually eliminated.

While various embodiments of the invention have been shown and described, it will be apparent to those skilled in the art that many modifications are possible. The invention, therefore, is not to be restricted except insofar as is necessitated by the prior art and by the spirit of the appended claims. I

What is claimed as the invention is:

1.
