[Technical field to which the invention belongs]
The present invention is a glass for simply determining the depth of a glass flaw in order to estimate the time and work required for the repair when partially repairing a flaw or a crack generated on the surface of a window glass of an automobile or the like. The present invention relates to a seal for easily determining the depth of a glass flaw using a light transmission shadow or a change in light transmission of a surface flaw.
[0002]
[Prior art]
Regarding a laminated glass repair system for repairing a scratch or a crack generated in a window of an automobile, in particular, when partially repairing a glass surface, the present applicant has already applied for a temporary repair seal for an automobile window suitable for this repair ( Patent Document 1).
[0003]
If the repair temporary seal is damaged or cracked in the windshield or rear window glass of the vehicle while the vehicle is running, the repaired temporary seal is damaged or cracked in the windshield or the like (hereinafter referred to as "damage"). If the repair work must be performed after a long time after the damage in the glass repair system that repairs only the part, dust and raindrops may permeate the damaged part during this time. Therefore, before starting the repair work, temporarily attach to the damaged part, and before starting the repair work, attach a transparent film of a predetermined size and shape before the repair work, and apply moisture or dust to the damaged part. , Water repellent components and the like.
[0004]
That is, as shown in FIG. 5, when a partial damage 11 occurs in the vehicle window glass 10 (see FIG. 5A), the temporary seal 20 is temporarily attached to the damaged portion 11 without keeping the interval as much as possible. When the repair work is to be started (see FIG. 5B), the temporary seal 20 is peeled off (see FIG. 5C), and then the damaged portion 11 is exposed, and the damaged portion 11 is exposed.

[Problems to be solved by the invention]
However, even if the repair work of an automobile window glass is performed exclusively by a car repairman, recently, regarding this repair, a person who receives a repair request may be different from an actual repairer.
[0006]
In such a case, the repairer can estimate the repair cost instantly by looking at the damage condition, but as described above, the person who receives the repair request is not familiar with the repair. In such a case, there was a problem that it was not possible to examine how much the repair cost would be in the actual repair just by looking at the damaged portion.
[0007]
In other words, I thought that it was minor damage and made a small cost estimate, but in fact it was a big damage and I had to charge more than the estimated cost, or I made a high cost estimate that it was a big damage However, in practice, there is a drawback that it becomes possible to know later that the cost was not so large. Particularly difficult to determine is the depth of the flaw. A deep wound, even on the surface that is not so large, requires considerable work to repair it.
[0008]
Because, when repairing a deep wound, it is necessary to scrape the area around the wound flat, and if mere scraping is not enough, if the smoothness is not maintained with the surroundings, the glass This is because the passed image looks distorted. However, it is difficult to determine whether the scratch on the glass surface is deep or shallow, even for a skilled person. For example, if 10 μm (μm), 5 μm (μm), and 2 μm (μm) scratches are collinear on the glass surface, even if 8 μm (μm) is polished and repaired, The remaining 2 micrometer (μm) scars will still remain.
[0009]
On the other hand, if only this deep flaw is polished and repaired, the above-mentioned distortion is generated in that portion, so that it is necessary to take a long time to grind and repair a wide area. The difficulty in repairing automotive window glass is determining the depth of the flaw and calculating the required working time for the flaw.
In particular, as described above, when the repair company of the automotive window glass repair work is different from the person who performs the reception work to receive the repair request, the responsibilities are prominent, and from this discrepancy, the underwriter of the glass repair work is No result.
[0010]
The present invention has been devised in consideration of the above-described disadvantages of the related art, and in the case where an automobile window glass is partially damaged, even a person who receives a repair request can easily calculate the repair cost. It is an object of the present invention to provide a glass flaw depth simple determination seal utilizing a light transmission shadow or a change in light transmission of a glass surface flaw which is easy to perform.

[Embodiment of the invention]
The glass flaw depth simple determination seal utilizing the light transmission shadow or light transmission change of the glass surface flaw according to the present invention is a translucent seal in which a plurality of line lines having a predetermined line width are printed and displayed in advance, A person who intends to discriminate can easily discriminate the depth of the damage by applying the damage depth simple discriminating seal to the damaged portion of the automobile window glass. That is, the present inventor has found that once the depth of the damage is known, the cost of the repair work can be roughly estimated, and by applying the finding to the glass flaw depth simple determination seal, This makes it possible to easily calculate an estimate of the repair work for the window glass repair.
[0013]
【Example】
One embodiment of the seal for simply determining the glass flaw depth using the light transmission shadow or light transmission change of the glass surface flaw according to the present invention will be described with reference to the drawings.
FIG. 1 is a schematic view showing a seal for simply determining a glass flaw depth using a light transmission shadow or a change in light transmission of a glass surface flaw for automotive window glass repair according to an embodiment of the present invention.
[0014]
A glass flaw depth simple discrimination seal 1 (hereinafter, sometimes referred to as "depth discrimination") using a light transmission shadow or light transmission change of a glass surface flaw using a light transmission shadow or light transmission change of a glass surface flaw shown in FIG. The seal 1 is made of a translucent polyethylene base material 2 having a length of about 70 mm, a width of about 35 mm, and a thickness of 1 μm ± 5 μm, and the surface thereof is formed as shown in FIG. At the right end, a number display section 3 on which numbers 1, 5, 10, and 15 are displayed, and a line 4 having a line width of 0.2 mm corresponding to the number display next to the position of the number 5 A line 5 having a line width of 0.3 mm corresponding to the numeral display next to the position 10 is a line 6 having a line width of 0.4 mm corresponding to the numeral display next to the position 15 of the numeral. Is displayed almost at full width at intervals of about 5 mm. It is made of the adhesive portion 7 formed of an acrylic solvent type transparent adhesive of approximately 20μm and the coating amount.
When not used, the depth discriminating seal 1 is formed on a release paper 8 of about 86 μm with a white glassine separator interposed.
[0015]
Next, an example in which the depth determination seal 1 is used to measure the depth of the damage generated in the window glass will be described. For example, if a linear damage occurs on the windshield of an automobile window glass, a person who measures the depth of the damage places the above-mentioned depth discriminating seal 1 on the damaged part as shown in FIG. It is stuck on the linear damage 11 at a right angle. FIG. 2 shows a state in which a linear damage 11 on the surface of the glass 10 is affixed at right angles to the depth determination seal 1.
[0016]
After attaching the above-mentioned depth discriminating seal 1 to the surface of the glass 10 in this way, the surface is illuminated by a predetermined light source 20. This light source may be a light bulb, an LED (semiconductor light source), or, in some cases, daylight in daylight. Any light source that emits light from a certain direction may be used. Then, for example, as shown in FIG. 3A, light 11 from the light source 20 is observed at a position 21a or 21b on the back surface of the glass 10. As for the position of the light source 20 and the observer, at a position where the damage 11 can be seen in the light from the light source, for example, at a position 21a, a straight shadow that can be said as a shadow of the damage 11 is seen. When the observer is at the position 21b, the damage 11 appears as a reflected shadow which can be said to be a reflection of the cross section of the opening of the damage 11.
[0017]
Although detailed knowledge of these causes is not known, by attaching the discrimination sheet 1 according to the present embodiment to the glass surface, irregular reflection on the glass surface is suppressed, and more light is absorbed in the glass. It is also imagined that the absorbed light is observed as a light transmission shadow or a change in light transmission corresponding to the depth of the flaw depending on the depth of the flaw on the glass surface. Is done.
[0018]
When the light from the light source 20 directly enters the eyes of the observer, the straight shadow or the reflected shadow may be difficult to see. Therefore, as shown in FIG. When observed in the above, the straight shadow and the reflected shadow of the damage 11 can be clearly seen. It is preferable that the observer changes the position as needed for observation. FIGS. 3A and 3B are diagrams showing that it is better to observe at a better position because the straight-ahead shadow and the reflected shadow are often seen or hard to see depending on the position of the light source 20 and the prosecutor.
[0019]
FIG. 4 schematically shows a state in which the straight shadow and the reflected shadow are visible. FIG. 4 shows a state in which there is a damage 11 having a certain depth on the surface of the glass 10, and the depth discrimination seal 1 is attached to the surface. The state when light is irradiated from the direction of the thick arrow is shown. When this is viewed by the observer at the position 21a, the damage 11 appears in a shadow state because the light is partially blocked or refracted in the light.
[0020]
In FIG. 4, this part is blocked or refracted and looks like a shadow (hereinafter, what is seen in this shadow is referred to as “straight shadow 31” for convenience). Further, when the observer looks at the position 21a in FIG. 4, the damage 11 is reflected by a part of the wall of the damage 11 and looks whitish (hereinafter, what is seen in this state is referred to as “reflection shadow” for convenience). 32 "). That is, as shown in FIG. 4, the flaw 11 having a certain depth on the surface of the glass 10 appears as a straight shadow 31 or a reflected shadow 32 with respect to the irradiated light depending on the observation position. In FIG. 4, reference numeral 31 denotes a straight shadow, and reference numeral 32 denotes a reflected shadow.
[0021]
Then, the inventor of the present application measured the relationship between the size of the straight shadow 31 or the reflected shadow 32 and the actual depth of the damage 11. The measurement was measured with a surf tester (surface roughness meter), and the depth of the wound was compared with the size of a straight or reflected shadow.
As a result, when the damage depth was 5 microns, the depth discrimination sheet 1 was displayed on the surface of the discrimination sheet 1 when the flaw 11 was illuminated with light and observed from the back by attaching the disc to the surface. It was found to look the same as a line width of 0.2 mm width. Similarly, a flaw with a depth of 10 μm on the surface of the glass 10 is the same as a line width of 0.3 mm width displayed on the surface of the discrimination sheet 1, and a flaw with a depth of 15 μm is similarly on the sheet 1. It was found to look the same as a 0.4 mm line width line on the surface.
[0022]
Therefore, as described above, when each line of the discrimination sheet 1 stuck at a right angle to the linear scratch 11 is compared with the straight shadow 31 or the reflection shadow 32, the depth of the scratch can be easily determined. .
Therefore, if the depth of the flaw can be determined, it is considered that the flaw in the repair work of the automobile glass or the like is a flaw within a repairable range, or that the flaw is within a feasible repair range. The degree can be easily known, and the cost required for the repair can be easily estimated.
[0023]
[Effect of the invention]
By doing so, even a layman who was difficult to calculate in the past can easily estimate the cost of repair work for automobile window glass repair, and not only professional repair operators but also many ordinary However, it is also possible to accept repairs for window glass repairs at shops and the like.
[0024]
In particular, it was difficult to determine the depth of scratches on the glass surface, so it was easy to overcome the difficulty of calculating the repair estimate, and the skilled worker was freed from calculating the estimate, contributing to the expansion of the repair business. It is possible to achieve a tremendous effect of doing so.
[0025]
Furthermore, since the degree of the depth of the damage can be known in advance, the repair operator can incorporate the work procedure in advance, and, for example, a long time is required for deep damage, so that a sufficient time can be allocated. Thus, the adjustment of the schedule can be taken into consideration, and there is an extremely excellent effect that the efficiency of the repair work as a whole is improved.
