SHEET 2 OF 2 INVENTORS HANS 0/5768 PEE/Z BY f/ERM/HM ZURSSE/l ATTOR YS ELECTRIC THERMAL WINDOW WITH AN ADJUSTABLE TERMINAL STRUCTURE This application is a continuation of my application Ser. No. 666,795, filed Sept. 1 l, 1967, and now abandoned.
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. As the thermal window is useful in automobiles to prevent fogging, icing and other accumulations, 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. In general, 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.
We have discovered the cause of this imperfection and have corrected it by this invention. 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.
The above and further objects and novel features of the present invention will more fully appear from the following detailed description when the same is read in connection with the accompanying drawings. It is to be expressly understood, however, that the drawings are for the purpose of illustration only and are not intended as a definition of the limits of the invention.
In the drawings, wherein like reference characters refer to like parts throughout the several views,
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; and
FIG. 5 is a perspective view of the preferred form of the invention.
In FIG. 1 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. In this novel construction 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. This leaves the length of the plate or strap portion of the terminal between 11, 12 free in the sense of being unattached to the glass, and the length of such portion is of small width, as provided by the spaces between the limbs of the E, which reduces the strength of the terminal and allows it to yield under the differing atmospheric conditions encountered in seasons and storms. We have also discovered that 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). In a terminal of copper or brass of about 0.5 mm. thickness the distance A may be on the order of 0.5 to 1 mm.
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,
capable of yielding readily to stresses imposed by temperature change or other conditions of operation.
The forms of FIGS. 1 to 3 have a projecting contact 8 which causes framing problems, but these have been overcome in FIGS. 4 and 5. In FIG. 4 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.
These new constructions yield readily to externally applied pressure, spare the connections and the pane, reduce the stresses caused by change in temperature and different rates of expansion, and eliminate the failures caused by prior constructions. The problems of framing, and elimination of projections capable of suffering shock are solved.
As many apparently widely different embodiments of the present invention may be made without departing from the spirit and scope thereof, it is to be understood that the invention is not limited to the specific embodiments.
