Definitions

  • a completed windshield antenna structure of a character that is technically and commercially acceptable to both the automotive inductry and its customers and that, at the same time, lends itself readily to production line installation on both stock and custom built automobiles.
  • a primary object of the invention is the provision of a structure of this character that can be rapidly produced to rigid specifications at a minimum of cost.
  • Another object is to provide such a structure that will function satisfactorily for its intended purpose, and that can be mounted in an automobile and electrically connected to the radio system more easily and permanently than prior known structures.
  • FIG. 1 is a fragmentary perspective view of the front end of an automobile provided with a windshieldantenna structure according to the invention
  • FIG. 2 is a quasi perspective, fragmentary, side view of the connecting area of the antenna windshield of FIG. 1, with portions broken away or removed to show the connecting tab and associated parts more clearly;
  • FIG. 3 is an enlarged perspective view of one end of the connecting tab of FIG. 2;
  • FIG. 4 is a fragmentary sectional view taken substantially along the lines 4-4 in FIG. 1;
  • FIG. 5 is a fragmentary sectional view taken substantially along the line 5-5 in FIG. 2;
  • FIG. 6 is a fragmentary plan view of an area of a plastic interlayer sheet showing the terminal ends of parallel antenna wires laid therein;
  • FIG. 7 is a view similar to FIG. 6, after the connecting tab has been positioned across the antenna wires and preliminarily heat-sealed to the plastic interlayer sheet;
  • FIG. 8 is a view similar to FIGS. 6 and 7 after the antenna wires have been wrapped around the connecting tab;
  • FIG. 9 is a similar view of the lead wire being soldered to the crossed antenna wires on the connecting tab
  • FIG. 10 is a view similar to FIG. 8 but showing a modified form of tab
  • FIG. 11 is a vertical, sectional view taken substantially along the line l1-ll in FIG. 10;
  • FIG. 12 is a view generally similar to FIGS. 8 and 10 showing still another form of tab and wrap.
  • FIGS. 1 and 2 there is illustrated in FIGS. 1 and 2 a complete antenna-windshield structure 10 of the general character contemplated by the invention, mounted in a conventional manner in an automobile 11, and comprising a laminated safety glass windshield 12 with a built in an tenna 13.
  • the windshield 12 is made up of two sheets of glass 14 and I5 and an interposed layer 16 of plastic all bonded together under heat and pressure to form a composite unit, and the lower edge of the outboard light or glass sheet 15 is notched or cut out prior to laminating to provide an indentation or opening 17 (FIGS. 2 and 5) in the finished windshield.
  • the antenna portion 13 of the structure 10 is contained between laminae of the windshield l2 and may be made up, first, of fine wire elements which preferably include both horizontal wire elements 18 and 19 and vertical wire elements 20 and 21.
  • the horizontal wire elements are located as near the upper edge of the windshield as consistent with adequate performance, for example from 1 /2 to 2 inches, and so are positioned well out of the critical sight areas in the windshield. Consequently, where a shade band is incorporated in the windshield, or where sun visors are used, these parts of the antenna will be completely hidden.
  • the vertical wire elements 20 and 21 which may be approximately inch apart, are located in the windshield midway between the driver and front seat passenger so that they are out of the critical sight area for either and will appear, if at all, only as a division line or lines.
  • these vertical wi're' elements also function as part of the special means for connecting the antenna-windshield structure to the radio than is an important feature of the invention.
  • vertical wire elements 20 and 21 extend downwardly from the inner ends of the horizontal wire elements 18 and 19 respectively toward the bottom edge of the windshield and, as best shown in FIGS. 2, 5 and 7 to 9, there is also provided between the laminae, and in alignment with the indentation 17 in the outboard lite of glass 15, a thin, flat, elongated metal plate or tab 24 under which the wires 20 and 21 extend, around which they are wrapped, and to which they are soldered or otherwise permanently secured.
  • one suitable and relatively simple procedure for doing so involves securing the antenna 13, including the connecting tab or plate 24, to or incorporating them in the plastic sheet that is to become the interlayer 16 before laminating it to the glass. This can be done for example by, first, embedding the wire elements of the antenna 13, under heat and pressure, into the surface of the plastic sheet on the side that will face the outboard sheet of glass in the finished windsheield (FIGS. 2 and 4) but leaving their lower ends free and extending out beyond the plastic sheet (FIG.
  • connecting tab 24 which may be of thin sheet copper or steel and is preferably phalange' or digital bone shaped in outline, symmetrically over the wire elements and 21; and heat sealing or otherwise bonding the mid portion of the tab, that lies between the wires, to the plastic sheet (FIG. 7).
  • the tab or plate 24 as illustrated in FIGS. 3 and 7, comprises a substantially rectangular middle portion 25, with generally semi-circular end portions 26 connected thereto by necks 27 formed by substantially semi-circular cuts 28; and the rectangular middle portion of the tab can be heat sealed to the plastic sheet by the application of approximately pounds pressure and a temperature of around 300 F. for about 4 seconds.
  • the loose end of the wire element 21, for example, is then wrapped upwardly, over and across the exposed surface of the mid portion of the tab 24, and down behind the neck portion, as indicated in broken lines in FIG. 7; after which the surplus length of the wire is cut off by a sharp upward tug against the lower edge of the curved neck of the connecting tab. Then the same thing is done with the loose end of the wire element 20 to leave the elements 20 and 21 crossed over one another at the center of the exposed surface of the rectangular portion 25 of the tab (FIG. 8).
  • the plastic sheet or interlayer 16, with the antenna wires and connecting tab incorporated therewith, is then assembled with two sheets of glass 14 and 15, and with the tab 24 in proper registry with the indentation 17 in the outboard sheet of glass 15 (FIGS. 2, 5 and 9).
  • the resulting assembly is then subjected to conventional prepressing procedures, usually involving roller pressing first at room temperatures and again after the assembly has been heated at around 150 F. This is preferably followed by a localized pressing over the entire area of the connecting tab 24, and against the portions of the interlayer l6 and of the glass sheet 14 that are in alignment therewith, while the assembly is still at the prepressing temperature.
  • a suitable pigtail or lead wire 30 (FIG. 9), which may be of tinned copper and suitably insulated, is soldered to the crossed wires 20 and 21 and, together with them, to the connecting tab 24 by a single high temperature soldering operation employing a soldering iron 31.
  • a solder alloy comprising 0.75% tin, 97.5% lead, 1.75% silver, and a suitable flux, such as Kester 1544, may be used with a metal temperature of from 900 to I,O0O F.
  • the final step of the procedure is to fill the indentation 17 in the glass and to cover the connecting plate and wires, with a heat and moisture resistant plastic sealing compound 32 such as Thiokol" (FIG. 5), after which the resulting windshield-antenna structure is ready for use and can be mounted in the windshield opening of an automobile in the same way that a conventional windshield for the same model is mounted. Also by providing the lead wire 30 with a suitable electrical connection, such as one half of a plug type fixture 33, installation of the device can be completed by simply plugging the connector 33 into the radio of the automobile.
  • a heat and moisture resistant plastic sealing compound 32 such as Thiokol"
  • tab which has been designated 24 and described in detail above
  • other specifically different forms may be employed and, indeed, may offer other or additional advantages.
  • the middle and end portions of the tab could be connected by other than the relatively narrow neck portions 27.
  • a tab 34 of the same general character as the tab 24 but which is of still different outline and is of lesser area.
  • the tab 34 comprises a middle portion 35, with curvilinear end portions 36 connected thereto by neck portions 37 that are formed by substantially semicircular or concave upper cuts 38 and lower cuts 39.
  • the cuts 39 also create a downward extension 40 from the middle portion 35, which extension can be bent outwardly away from the body of the tab 34 as shown in FIG. 11.
  • the entire tab (except for the outwardly bent portion) can be sealed by the heat and pressure to the interlayer 16' as soon as it has been placed over the wires 20' and 21'.
  • the uncovered end of first one and then the other of the wires 20' and 21 are brought over and wrapped, preferably twice, around the outwardly bent extension 40 and broken off by a sharp tug against its edge.
  • the wires that are wrapped around the tab will not necessarily be in crossing, although they will always be in contacting, relationship; and, as described in connection with the tab 24, can have a pigtail or connecting wire soldered to the contacting wires 20 and 21 and, together with them, to the connecting tab 34 by a single soldering operation.
  • FIG. 12 Another desirable modification is illustrated in FIG. 12 wherein a tab 44, of the same form as the tab 24 of FIGS. 2 through 9, and having a similar mid portion 45 and end portions 46 connected thereto by necks 47, is located on a plastic sheet 16" and in the same relation to antenna wires 20" and 21" carried thereby as was the tab 24.
  • the portion of the tab 44 that is initially heat sealed to the plastic sheet 16" includes, along with the mid portion 45, portions of the necks 47 to provide an adhered or sealed area outlined by broken lines 48 and which includes extensions 49 and 50 from the mid portion 45, which extensions seal the wires 20" and 21" between the tab 44 and the plastic sheet 16" and bond them thereto.
  • the loose end of the wire 20 is then wrapped parallel to the tab 46 around the seal at the extension 49, then downwardly across the exposed face of the tab 44 to the low side of the opposite neck 47, then under this neck of the tab, after which the excess length of the wire is broken off by a sharp tug outwardly and downwardly against the sharp upper side of the neck of the tab.
  • the loose end of the other wire, 21" in this case is then wrapped in a reverse manner around the seal at the extension 50, across the exposed face of the tab 44, and behind the opposite neck portion 47 before tugging it outwardly and downwardly to break off the surplus. Thereafter, the completion of an antenna windshield incorporationg the tab 44 in the arrangement illustrated in FIG. 12, and the soldering of the crossed wires 20" and 21", will be the same as that described in connection with the tab 24.
  • connecting tabs can be envisiond for obtaining a variety of specifically differing results.
  • the undercuts 28 may be made much deeper. This will have two advantages, the first being that the wrapped wires will be farther upward away from the bottom edge of the laminated structure, and the second that total area of the tab will be less, with correspondingly less capacitance to ground.
  • tab 34 which, in addition, permits faster heat up in the solder area; and both the tabs 34 and 44 exhibit increased resistance to wrapped wire and pigtail pull, the former because of the presence of the extension 40, and the latter because of the service loop in the wires around the extensions 49 and 50 in the initial seal.
  • a laminated safety glass windshield comprising alternate sheets of glass and plastic bonded together in face-to-face relation and having a radio circuit supported on one of said sheets.
  • which circuit includes horizontally disposed wire elements with spaced, parallel, vertically disposed wire elements extending downwardly therefrom; the improvement in which an elongated connecting tab having a middle portion, opposite end portions, and portions connecting said end portions to said middle portion is disposed across and in contact with said vertically disposed wire elements, and each of the wires of said spaced, parallel, vertically disposed elements is wrapped over an edge of one of said connecting portions of said tab while in spaced relation to the other wire of said elements and extends therefrom toward said other wire and is then wrapped around the other connecting portion of said tab.
  • an antenna windshield structure which is made up of alternate sheets of glass and plastic bonded together in face-to-face relation and has a radio circuit that includes spaced, parallel, vertically disposed wires supported on one of said sheets, the steps of supporting said circuit on said sheet with the ends of said vertically disposed wires unattached to said sheet adjacent its lower edge, locating an elongated metal connecting tab having a middle portion, opposite end portions, and portions connecting said end portions to said middle portion across said wires on said supporting sheet, bonding said middle portion of the tab to the surface of said supporting sheet between said wires, and wrapping the loose ends of each of said spaced wires first over an edge of one of said connecting portions of said tab then across the face of the middle portion of the tab and over and behind an edge of the opposite tab connecting portion to cross each other on the face of said tab.
  • said supporting sheet is a sheet of plastic
  • said circuit is embedded in a surface of said supporting sheet, the portion of said tab lying between said parallel wires is heat sealed to said supporting sheet before wrapping said wires and the end portions of said tab are heat sealed to said supporting sheet after wrapping said wires.
  • an antenna windshield structure which is made up of alternating sheets of glass and plastic bonded together in face-to-face relation and has a radio circuit that includes spaced, parallel, vertically disposed wires supported on one of said sheets, the steps of supporting said circuit on said sheet with the ends of said vertically disposed wires unattached to said supporting sheet adjacent its lower edge, locating an elongated metal connecting tab having a middle portion, opposite end portions, and portions connecting said end portions to said middle portion across said wires on said supporting sheet, said tab also including an extension projecting outwardly from said middle portion and out of the plane of the supporting sheet, bonding said tab other than said extension thereof to the surface of said supporting sheet, and wrapping the loose ends of each of said spaced wires to said tab by passing said wires from under said connecting portions of said tab and then toward each other and wrapping them around said outwardly projecting extension and in contact with each other.
