本考案は、加熱可能透明体に係り、例えば複式給電型加熱可能風防に関する。 The present invention relates to a heatable transparent body, for example, to a multiple power feed type heatable windshield.

透明体の温度を上げるためにその上の透明な導電性被膜に電流を流すことは知 られている。一般に、この透明体は、導電性被膜によって電気的に相互接続され た１対の離間した母線を含む。これらの母線は、通常リードによって電源に接続 されていて、この電源からの電流をこの被膜を通して分布する。この透明体が積 層風防である場合、この被膜を通る電流は、この風防の露出面に積った雪又は氷 を溶かすに十分にこの積層体表面の温度を上げる。 It is known to pass an electric current through the transparent conductive coating above it to raise the temperature of the transparent body. Generally, the transparency includes a pair of spaced busbars electrically interconnected by a conductive coating. These busbars are typically connected to a power source by leads that distribute current from the power source through the coating. If the transparency is a laminated windshield, the current through the coating raises the temperature of the laminate surface sufficiently to melt the snow or ice on the exposed surface of the windshield.
【０００３】 加熱可能風防は、通常、この風防の層の一つの縁に沿った切込み部又は切欠き 領域を含み、その領域が母線のリード部を露出し、この電源をこの風防に接続で きる場所を提供する。この切欠き領域は、この風防のリードを短絡するおそれの ある湿気がこの切欠き領域に入るのを防ぐため、この露出したリードに電気接続 を行ってから密封しなければならない。A heatable windshield typically includes a cutout or cutout region along one edge of the layer of the windshield, which region exposes the leads of the busbar to which the power supply can be connected to the windshield. Provide a place. The cutout area must be sealed after making electrical connection to the exposed lead to prevent moisture from entering the cutout area, which could short the lead of the windshield.
【０００４】 ギラリーの米国特許第４，８２０，９０２号及び第４，９４０，８８４号に開 示されているような複式リードの加熱可能風防では、これらの母線の少くとも一 つへの電流は２本のリードによって供給される。クンツの米国特許出願０７／４ ４４，２０６が教示するような、複式リードが熱可能風防装置用の亀裂検出器も 二つの電気接続を伴う２本の検出器線を要する。一般に、これらの電気接続は各 々この切欠き領域で行われる。複式リード加熱可能風防に電力を与え且つ監視す るために要する電気接続の数を減らすことは有利だろう。In dual lead heatable windshields such as those disclosed in Guillary US Pat. Nos. 4,820,902 and 4,940,884, the current to at least one of these busbars is Supplied with two leads. A crack detector for a dual lead heatable windshield, as taught by Kuntz US patent application 07/4 44,206, also requires two detector lines with two electrical connections. Generally, each of these electrical connections is made in this cutout area. It would be advantageous to reduce the number of electrical connections required to power and monitor dual lead heatable windshields.

In a preferred embodiment of the present invention, but not a limitation of the present invention, the windshield 10 comprises a heating device that includes a conductive coating 18 preferably located on the inside surface 20 of the outer glass layer 12. Various coatings may exhibit the necessary combination of transparency and the electrical conductivity required to act as a heating element for this transparency 10. The preferred coatings are similar to those disclosed in Gillary U.S. Pat. No. 4,610,771, the disclosure of which is incorporated herein by reference. These coatings generally include one or more silver films between a pair of zinc stannate films, each of which may be sequentially applied by magnetron sputtering.

Similar to the dual feed bus bar device disclosed in 820,902, the disclosure of which is incorporated herein by reference. Referring to FIG. 1, a lower bus bar 24 and an upper bus bar 26 are arranged along the surface 20 of the glass layer 12 and in contact with the coating 18. Electrical connection to this top busbar 26 is made by a pair of extensions, or leads 28 and 30, of this busbar 26, each of which extends along opposite sides and bottom edge of the windshield 10 to a terminal region 32. The lead 28 further includes an extension 34 that extends to the edge of the outer glass layer 12 of the windshield 10, as discussed in more detail below. The electrical connection to this lower bus bar 24 is made by a lead 36 extending from this bus bar 24 in the terminal region 32 to the edge of the layer 12. While not limiting in the present invention, this terminal area 32 is preferably along the bottom edge of the windshield 10 as shown in FIGS. 1 and 2, but at a convenient location on the periphery of the windshield 10. It should be understood that it can be anywhere.
【００１３】 これらのリード２８及び３０は、この被膜１８への電力が母線２４及び２６を 通してのみ供給されることを保証するため、この技術分野で知られた何れかの都 合のよい方法で、この被膜１８及び下母線２４から電気的に絶縁されている。本 考案では限定的ではないが、この被膜１８の縁は、図１及び図２に線３８で示す ように、この透明体１０の縁から離間していて、リード２８及び３０はこの被覆 されない、周辺領域に配置されている。These leads 28 and 30 ensure that power to the coating 18 is provided only through the busbars 24 and 26, and may be any suitable method known in the art. Are electrically insulated from the coating 18 and the lower bus bar 24. Although not limiting in the present invention, the edge of the coating 18 is spaced from the edge of the transparent body 10 as shown by the line 38 in FIGS. 1 and 2, and the leads 28 and 30 are not coated. It is located in the peripheral area.
【００１４】 これらの母線及びリードは、この技術分野でよく知られているように、銀を含 むセラミックのフリット材料で作られているのが好ましく、且つ何れかの都合の よい方法、例えばスクリーン印刷でこのガラス層１２のガラス面２０につけても よい。印刷の後、このフリット材料を加熱するか“焼いて”、このフリット材料 を融解し、ガラス面上に溶融する。これらの母線２４及び２６並びにリード２８ 及び３０の一部又は全部をかくすため、不透明なセラミックエナメル縁（図示せ ず）をこのガラス層１２の表面２０につけるのは任意である。These busbars and leads are preferably made of a ceramic frit material containing silver, as is well known in the art, and any convenient method, such as a screen. It may be attached to the glass surface 20 of the glass layer 12 by printing. After printing, the frit material is heated or "baked" to melt the frit material and melt it onto the glass surface. An opaque ceramic enamel edge (not shown) is optionally applied to the surface 20 of this glass layer 12 to hide some or all of these busbars 24 and 26 and leads 28 and 30.
【００１５】 母線及びリードをこのガラス層１２に焼付け且つ被膜１８を表面２０に付けて から、図２及び図３に示すように母線ジャンパ部材４０をガラス層１２に付ける 。特に、ジャンパ部材４０は、リード２８の端４２をリード３０の端４４と電気 的に相互接続する導電性部材である。このジャンパ部材４０の大きさは、一部そ こを通過して上母線２６に給電する電流の量に依る。一つの特別な加熱可能風防 の構成では、２０アンペアの電流がこの上母線２６に与えられ、各母線リードが 完全に機能していれば、１０アンペア、即ち全電流の半分が各リード２８及び３ ０を通して伝導される。もし、リードの一つが破損し、それでもこの風防１０が 機能し続けるなら、このジャンパ部材４０は全電流負荷をこの上母線２６に伝達 できなければならない。本考案では限定的ではないが、０．９５ｃｍ×１０．１ ６ｃｍで厚さ０．０９ｍｍの銅の小片を導電性接着剤（図示せず）で端４２と４ ４に固着して上に議論した２０アンペアの電流負荷に対するジャンパ部材４０と して使った。図２及び図３に示した特定の実施例でのジャンパ部材４０は下母線 ２４のリード３６を横切って伸びるので、限定はされないが絶縁テープ又はポリ エステルテープのような誘電体材料４６をこのリード３６とジャンパ部材４０の 中央部４８との間に配置し、この電源の風防１０への電気的短絡を防止する。好 ましいジャンパ４０配置では、この導電性接着剤を銅小片の下面に付け、絶縁テ ープ４６をこの小片の中央部４８に直接固着してこのジャンパ部材４０に接着剤 の包帯をしたかのようにする。この種の構成で、このジャンパ部材４０を１回の 作業で付けることができる。The busbars and leads are baked onto the glass layer 12 and the coating 18 is applied to the surface 20, and then the busbar jumper member 40 is applied to the glass layer 12 as shown in FIGS. 2 and 3. In particular, jumper member 40 is a conductive member that electrically interconnects end 42 of lead 28 with end 44 of lead 30. The size of the jumper member 40 depends on the amount of current passing through the jumper member 40 and feeding the upper bus bar 26. In one particular heatable windshield configuration, 20 amps of current is applied to this upper bus bar 26, and if each bus bar lead is fully functional, 10 amps, or half of the total current, is applied to each lead 28 and 3.
