Definitions

  • Mayewsky Attorney-Bauer & Seymour ABSTRACT A thermal window having a glass pane, an electrical heating grid including bus bands affixed to the glass pane, and flat terminals having spaced portions fixedly attached to the bus bands at spaced points.
  • the terminal intermediate the fixed points of attachment being free of attachment to the glass pane and the bus band and capable of easy change in dimension in response to external stimuli.
  • This invention relates to the construction of thermal windows (c.f. French Pat. No. 1,464,585) and particularly to the assemblage of the pane, the heating grid, and the terminal.
  • thermal windows c.f. French Pat. No. 1,464,585
  • the description will proceed with that structure in view as exemplary.
  • Thermal windows of the type improved by this invention, have a glass pane which in automobiles is plain, triplex, or tempered, to one face of which a heating grid is attached as illustrated in FIG. 5.
  • the grid may be resistance metal or resistance composition, may be in various forms either truly grid or so termed by courtesy, the shape, type, and method of attachment to the glass being part of the prior art unnecessary to be described here.
  • such windows have bus bands extending across opposite edges of the glass, between which extend the heating resistances.
  • Electrical terminals are very sensitive to the effects of changes in temperature, strong strains forming parallel to the glass because of their differences in coefficients of expansion, frequently detaching the terminal from the glass and sometimes cracking its outer surface, in either case making it useless.
  • the invention involves a thermal window comprising a glass pane, a heating grid including a bus band affixed to the glass, and a terminal fixedly attached to the bus band and to the glass at spaced points, the terminal intermediate the fixed points of attachment being free, of attachment to the glass and the bus band, and capable of easy change in dimension in response to external stimuli.
  • FIG. 1 is a perspective view of a portion of a thermal window of the simplest form according to this invention
  • FIG. 2 is a plan view, partly in section, of the connection between the terminal and the grid and glass;
  • FIG. 3 is a perspective view of an improved form of the invention.
  • FIG. 4 is a perspective view of another form of the invention.
  • FIG. 5 is a perspective view of the preferred form of the invention.
  • the window pane l bears an affixed heating grid 2-3 the bars 2 of which extend between bus bands 3, only one of which is shown.
  • the bars and bands are of some known construction mounted on the pane by known methods.
  • the electrical terminals are constructed of flat plates 5, 6, 7 shaped like the letter E, the central limb of which is extended at 8 to form a contact to which the contact of the lead will be attached, eg as in FIG. 4.
  • the limbs 5, 6 are alone attached to the grid and the glass, the method of attachment being that used in the prior art, and the areas of attachment 11, 12 (FIG. 2) are small and are spaced apart.
  • the total width of limbs 5 and 6 may advantageously be less than the width of the bus band by an amount A (FIG. 1).
  • the distance A may be on the order of 0.5 to 1 mm.
  • FIG. 3 An advantageous form of the invention is illustrated in FIG. 3 wherein the central or strap part 13 of the terminal is offset at 14, 15 from the pane and the bus band, furnishing a readily deformable connection, between the points of attachment,
  • FIGS. 1 to 3 have a projecting contact 8 which causes framing problems, but these have been overcome in FIGS. 4 and 5.
  • the oifset 13 is projected at 14 and 15 over and parallel to the edge of the pane, the part 15 being flush against but not attached to the pane and the contact 16 being displaced enough from the pane to seat the cooperating contact 18.
  • the preferred form of the invention shown in FIG. 3 has the plate 5', 6', 13' parallel to the edge of the pane, two tabs 21, 22 are bent over the edge of the pane and soldered to the bus band 3, and two contacts 23,, 24 which are the ends of a single band attached at its middle to the offset strap 13'.
  • This construction is recessed (25,25) in the side of the pane so that all problems of framing are eliminated.
  • a similar reduction at the end of the pane of FIG. 4 accomplishes a like result.
  • a thermal window comprising a glass pane, a heating grid including a bus band affixed to the glass pane, and a terminal having spaced portions fixedly attached to the bus band at spaced points, the terminal intermediate the fixed points of attachment being free of attachment to the glass pane and the bus band and capable of easy change in dimension in response to external stimuli, said terminal having a strap portion attached to said spaced portions and an intermediate part which is offset from the spaced portions, the width of the bus band being greater than the width of the spaced portions of the terminal attached thereto, and in which the terminal lies parallel to the edge of the glass pane, is attached to the bus band by spaced arms and has a contact attached to the offset part of the strap portion extending parallel to the edge of the glass pane.
  • a thermal window comprising a glass pane, a heating grid including a bus band affixed to the glass pane, and a terminal having spaced portions fixedly attached to the bus band at spaced points, the terminal intermediate the fixed points of attachment being free of attachment to the glass pane and the bus band and capable of easy change in dimension in response to external stimuli, in which the terminal has a strap portion attached to said spaced portions thereof, and at least a part of the strap portion is offset and overlies and is parallel to the edge of the glass pane and is provided with a contact parallel to the edge of the glass pane.
  • a thermal window comprising a glass pane, a heating grid including a bus band affixed to the glass pane, and a terminal having spaced portions fixedly attached to the bus band at spaced points, the terminal intermediate the fixed points of attachment being free of attachment to the glass pane and the bus band and capable of easy change in dimension in response to external stimuli, the said glass pane having a recess in a portion of its outline, and the terminal is disposed in said recess.
  • a thermal window comprising a glass pane, a heating grid including a bus band afiixed to the glass pane, and a terminal having spaced portions fixedly attached to the bus band at spaced points, the terminal intermediate the fixed points of attachment being free of attachment to the glass pane and the bus band and capable of easy change in dimension in response to external stimuli, in which the terminal has a strap portion attached to said spaced portions and.
  • the strap portion has an intermediate part which is offset from the spaced portions, the bus band overlying and extending along a broad surface of the glass pane adjacent an edge thereof, the strap portion overlying the edge of the glass pane, and the spaced portions of the terminal comprise angular elements one arm of each of which overlies the edge of the glass pane and is attached to the respective end of the strap portion, and the other arm of which overlies and is attached to the bus band.
  • a thermal window according to claim 4 in which the glass pane has a recess in a portion of its outline, and the terminal is disposed in said recess.
  • a thermal window according to claim 5, comprising a contact attached to the strap portion of the terminal, and the contact is disposed in said recess.
  • a thermal window comprising a glass pane and a heating grid therefor, including a bus band fixed to and extending along an edge portion of the glass pane, the improvement comprising, an elongated plate having end portions spaced and interconnected by an intermediate portion, said end portions only being directly and fixedly attached to said bus band at locations spaced longitudinally therealong, and electrical contact means connected with said intermediate portion.
  • said contact means comprising a strap integrally connected at one end with said intermediate portion and extending, first outwardly parallel with the glass pane, across the contiguous edge thereof, then downwardly and transversely across said contiguous edge, to
