Definitions

  • the present invention relates to glazing, and more particularly, to glazing including busbars having one or more openings formed on the surface thereof.
  • Glazing according to the present invention is particularly used as a glass for a vehicle, that is, a front window glass, a rear window glass, and a side window glass for a vehicle.
  • the glass for the automobile is bonded to a window frame generally using urethane.
  • Enamel(referred to as "black enamel”) whose color changes into black after heat treatment is printed on a peripheral portion of the glass in order to prevent defect generation of a bonding portion by ultraviolet rays and to hide defects as illustrated in Figs. 1 and 2A.
  • Fig. 1 is a front view of conventional glazing used as front window glass of a vehicle
  • Fig. 2A is a front view of conventional glazing used as rear window glass of a vehicle.
  • black enamel 3 is printed on a peripheral portion of a front window glass 1.
  • a hot wire 5 containing Ag and a busbar 7 for supplying a current to the hot wire 5 are printed on a lower end of the front window 1.
  • black enamel 13 is printed on a peripheral portion of a rear window glass 11
  • busbars 17 for supplying a current to a hot wire 15 are printed on both sides of the rear window glass 11 , respectively.
  • a plurality of hot wires 15 connected to the busbars 17 is formed along a width direction of the rear window glass.
  • the hot wires 5 and 15 and the busbars 7 and 17 formed by heat- treating Ag paste prevent a window glass for a vehicle from being dimmed by the frost or the snow and thus providing poor sight during winter, and heat the window glass so that frozen wipers not in operation can be easily detached and moved. Meanwhile, since the Ag paste is white, the Ag paste is easily seen to the outside of a vehicle when applied to a front window glass and a rear window glass of a vehicle. Therefore, portions to which the Ag paste has been applied, that is, the hot wires 5 and 15, and the busbars 7 and 17 need to be hidden using the black enamel 3 and 13 in order to make the glass of a vehicle elegant.
  • the black enamel 3 and 13 is not applied to only portions to which the Ag paste has been applied but applied to an entire peripheral portion of the window glass.
  • the black enamel 3 and 13 should have opacity in order to properly hide the Ag paste.
  • the black enamel is printed in advance in the form of paste containing glass frit existing in a suspension state inside an organic medium and black pigment using a silk screen method before the Ag paste is printed on a glass substrate.
  • the black enamel is printed in advance on an inner side of the window glass and then the Ag paste is printed on the inner side to overlap the black enamel.
  • the above-formed glazing is heat-treated using usually radiant heat at a temperature range of about 600-700°C in order to bake the black enamel and the Ag paste.
  • a connector connected to a battery of a vehicle is connected to the busbar through soldering.
  • the black enamel 13 does not always represent uniform black color but generates a gray region 17 in the busbar portion that overlaps with the Ag paste.
  • There is a blot of the busbar which can be seen at the exterior of a vehicle. The wider an area of the Ag paste that overlaps with the black enamel is, the more this undesired blot called "milky" is generated.
  • the present invention is directed to glazing that substantially obviates one or more problems due to limitations and disadvantages of the related art.
  • An object of the present invention is to provide glazing that allows heat to be uniformly dispersed over an entire surface of the glazing by allowing radiant heat to be easily transferred toward black enamel located under a busbar formed of Ag paste during a heat treatment process for the glazing.
  • glazing including a busbar having one or more openings that allow a heat-generating ray such as infrared rays to pass through a surface portion of the busbar during a heat treatment process.
  • the entire area of the one or more openings occupies 10-95% of a surface area of the busbar, and preferably, occupies 50-95% of the surface area of the busbar.
  • a heating net formed of Ag paste is formed in a width direction of the glazing between busbars, and the heating net may be formed in a silk screen method.
  • a surface area of the busbar should be increased in order to guarantee an electrical characteristic. That is, when the area of the busbar through which a current can flow is reduced due to the openings formed in the busbar, density of a current flowing through the busbar increases. Further, when the density of the current exceeds a predetermined level, a fire may break out in the busbar. For example, when the openings occupy 50% of the surface area of the busbar, the surface area of the busbar should be increased twice.
  • a shape of the opening formed in the busbar and then allowing a heat-generating radiant ray to pass through includes a square, a rectangle, a diamond, a circle, and an oval.
  • the shape of the busbar should be compatible with a function of the busbar delivering a current. That is, an entire surface of the busbar must have a shape of an opening that does not generate discontinuity in Ag paste of the busbar.
  • the opening can be distributed in the same size or a gradually changing size in the busbar with consideration of an aesthetic aspect and an electrical characteristic.
  • an area of the busbar that has been reduced due to the opening can be compensated for by increasing a thickness of the busbar.
  • total resistance of the hot wires are identical for both the case where there exists the openings in the busbar for allowing passing of a heat-generating radiant ray and the case where there does not exist the openings.
  • This busbar accommodates a connector connected to a cable for delivering a current from a battery of a vehicle.
  • the connector is soldered on the busbar, and a busbar portion on which the connector is soldered does not include the opening. If a surface portion of the busbar where the connector is accommodated is limited, it is possible to reduce the danger that a portion of the black enamel that is located under the busbar is insufficiently baked.
  • glazing according to the present invention can be constituted by a single glass substrate including busbars having one or more openings.
  • the glazing according to the present invention can be constituted by overlapping a plurality of glass substrates including busbars having one or more openings. Two sheets of glass are coupled to each other using polyvinyl butyral (PVB) for example. In this case, it is preferable that the busbars are located on the second glass surface or the fourth glass surface when the glazing is finally formed.
  • PVB polyvinyl butyral
  • Fig. 1 is a front view of related art glazing used as a front window glass of a vehicle
  • Fig. 2A is a front view of related art glazing used as a rear window glass of a vehicle
  • Fig. 2B is a backside view of the glazing of Fig. 2A;
  • Fig. 3A is a front view of glazing having busbars according to an embodiment of the present invention

  • Fig. 3B is an enlarged view of a busbar portion in which openings of lattice patterns are formed
  • Fig. 3C is a view illustrating an outer side of the glazing of Fig. 3A.
  • a portion that looks black in the lattice patterns of Figs. 3A and 3B is black enamel seen through an opening formed in the busbar.
  • a busbar 27 of glazing 21 includes an opening 29 of lattice patterns. Accordingly, some of heat-generating radiant rays are reflected by Ag paste 31 of the busbar 27 and the other heat-generating radiant rays pass through the opening 29 to reach a portion of the black enamel that is located under the busbar 27.
  • the reason why the opening 29 looks black in Fig. 3B is that the black enamel printed under the white Ag paste 31 is seen through the opening 29.
  • the black enamel is sufficiently baked to represent proper black color sufficient to hide the busbar existing on said black enamel. That is, since a gray busbar is not observed any more from an outer side of the glazing according to the present invention, a "milky” effect is suppressed, which is apparent from Fig. 3C.
  • Fig. 4 illustrates the busbar 27 including an opening 29 of various shapes that can be provided to glazing according to the present invention.
  • Heat-generating radiant rays can reach the black enamel sufficiently through the opening of a shape such as a square, a rectangle, a circle, and an oval.
  • the reason why the opening 29 formed in the busbar 27 looks black in Fig. 4 is to describe the black enamel printed under the Ag paste of the busbar.
  • Fig. 5 is a cross-sectional view of laminated glass 41 including glazing according to the present invention.
  • the laminated glass 41 means glass formed by interposing a transparent organic layer between two sheets of glass and closely attaching the two sheets of glass to provide safety.
