Abstract

PURPOSE:To simplify the process of work by engraving a positioning mark of a holder simultaneously at the time of engraving a trade mark ny a sand blast. CONSTITUTION:A trade mark and a positioning mark are simultaneously engraved by drawing a cutting line on a side window glass 1 by a cutting device arranged on the upper part of a positioned material plate glass, simultaneously blowing abrasive sand from mask plates 3', 6' of a trade mark marking device 7 and a pair of position making devices 8 provided on the lower part of the glass juxtaposed with each other. The side window glass 1 folded and separated from the cutting line is moved in a heating furnace and receives a bending moulding process. As the positioning markis engraved simultaneously with the trade mark by the sand blast, no new process is required, and an etched mark is not dispositioned nor lost by a following process.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle window glass, and more particularly to a side window glass thereof.

[0002]

2. Description of the Related Art The side window glass of an automobile is moved up and down by a hand operation, and the window is opened and closed by raising and lowering it. However, the window glass is connected to a vertically moving mechanism incorporated for raising and lowering through a holder. For the attachment of the holder, see, for example
The publication No. 69 and the publication No. 53-25931 are
Disclosed is a screw or bolt-nut on the lower edge of the window glass, or a holder made of a hard synthetic resin having a U groove for holding the lower edge of the window glass, which is fixed with an adhesive. Regarding the window glass, for example, in Japanese Utility Model Laid-Open No. 3-75015, a window glass in which white portions are formed at appropriate intervals on a ceramic coating portion that is painted near the periphery of the vehicle window glass is formed. The ceramic coating part shape is disclosed.

[0003]

If the position of the holder attached to the window glass is not accurate, it cannot be connected to the vertical movement mechanism incorporated in the body of the vehicle, and even if it can be connected by force. The opening and closing of the elevator is not done smoothly, and in order to fix it in the correct position, mark the attachment position of the holder on the inspection jig of glass size and curvature in advance, and place the dummy glass on the inspection jig. Since the marking position is transferred and the holder mounting machine is set on the basis of the dummy glass, due to a slight error generated from the transfer from the inspection jig, the setting of the mounting machine from the dummy glass, or the like, There is a problem such as lifting failure caused by poor connection to the vertical movement mechanism built into the vehicle. Window glass is also possible to form a white portion provided coated part is limited to the glass of the front or Rya, the side window glass has a problem that can not be adopted.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is possible to accurately and surely position a holder fixed to a window glass without a new process. For the purpose of being able to do so, in a vehicle window glass in which a holder provided between a vertical movement mechanism for vertically moving the window glass is positioned and fixed to the lower edge of the glass, a mounting positioning mark of the holder is attached to the window glass. The present invention provides a window glass for a vehicle that is engraved at the same time as an engraved trademark mark, and it is more preferable that the positioning mark and the trademark mark are engraved by sandblasting.

[0005]

[Function] In the pretreatment before cutting, which is cut out from the raw glass plate, the trademark mark is engraved by sandblasting and the positioning mark of the holder is engraved at the same time, so no new process is required. The error due to the positioning means by the glass for use disappears.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view showing a partially cut side window glass according to the present invention and a holder before attachment, FIG. 2 is an overall view of the side window glass according to the present invention, and FIG. 3 is an arrangement of a marking device. The schematic diagram to demonstrate is shown.

The side window glass 1 is provided with a cutting device (not shown) provided on an upper portion of the positioned raw sheet glass to give a cutting scoring line, and at the same time, a pair of positioning devices with a trademark marking device 7 arranged under the glass. Side windows cut off from the scoring line by jetting grinding sand from the mask plates 3 ', 6', 6'of the marking device 8, 8 to engrave the trademark mark 3 and the positioning marks 6, 6 at the same time. The glass 1 moves in a heating furnace which is the next step and undergoes bending forming processing.

The bent side window glass 1 is
A holder 2 having a concave portion 4 made of resin or metal and a bolt hole 5 is attached to the lower edge of the glass 1 that has passed the inspection of dimensions and curvature by an inspection jig, but the holder is not shown in the figure. Positioning mark 6 by machine
One side of the holder 2 is aligned with and the concave portion 4 is inserted into the window glass 1 via an adhesive agent, and when the adhesive agent is cured, it is carried into a vehicle assembly factory, and a side window up / down mechanism incorporated in a vehicle door is installed. By connecting the bolt holes 5,
The side window glass 1 is moved up and down by operating the vertical movement mechanism.

The operation of the present invention will be described below. At the same time as the trademark mark 3 by sandblasting, the positioning mark 6,
No new process is required by engraving 6, and the etched mark is not displaced or disappeared in the next process. When mounting the holders 2 and 2, the positioning mark 6 and the base point of the holder 2 are aligned with each other. The holders 2 and 2 attached to the window glass 1 can be attached accurately and reliably even in the setting with the vertical movement mechanism, and can be smoothly moved up and down without raising and lowering even during its lifting operation. To do.

Although the center mark for attachment is also provided in the rear window, it may be engraved at the same time as the trademark mark as described above, and the engraved portion is not clear for the center mark provided on the windshield or the like for print printing. In such a case, it goes without saying that a marking may be provided on the printed surface of the print instead of sandblasting.

[0011]

INDUSTRIAL APPLICABILITY The vehicle window glass of the present invention does not require a new step because the holder mounting position mark is engraved at the same time as the trademark mark by sandblasting.
Since the positioning accuracy of the etched mark is the same as the positioning when cutting the blank glass, it has a remarkable accuracy, and the positional deviation of the holder mounting machine can be easily found.
There is no defective assembly to the vehicle due to the position of the holder that is fixed to the window glass.
