Description

  The present invention relates to a method for removing a window glass for an automobile, and more particularly to a method for easily and quickly removing a relatively small automobile window glass such as a rear side glass of a minicar or a wagon car.

As a known technique related to a method for removing a window glass for an automobile, there is a method described in Patent Document 1 previously devised by the applicant of the present application.
The method disclosed in Patent Document 1 is an excellent method that can be performed very easily and smoothly compared to the conventional method when removing relatively large window glass such as a windshield and rear glass. However, in order to apply to a small window glass, the work is large, so that the workability is not so good.

In fact, when repairing a car body, it is often necessary to remove a relatively small window glass such as a rear side glass of a light car or a wagon car.
For example, when replacing the quarter panel around the rear side glass of a mini car or wagon car, it is necessary to peel off the spot welding, but spot welding always exists on the sheet metal part (body panel) of the car body to which the glass is attached. In order to peel off spot welding, it is necessary to remove the rear side glass.

  As described above, there are many scenes where it is necessary to remove a relatively small window glass in vehicle body repair, while the method disclosed in Patent Document 1 is easy to apply to small window glass as described above. Is not so good, so it was rarely used in the field.

  In addition, in the method disclosed in Patent Document 1, since it is necessary to work after cutting the molding with a cutter knife or the like, when attaching the window glass again, a new molding must be purchased, The cost increases accordingly, and it is not preferable from the viewpoint of resource saving.

As another example of the method for removing the window glass for automobiles, there is a method of softening the adhesive that bonds the glass and the vehicle body panel by applying heat from the outside of the glass with a far infrared heater or the like.
However, in this method, it takes time to soften the adhesive and power consumption increases, so that it cannot be said to be a preferable method in terms of both work efficiency and cost.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, a preferred embodiment of a method for removing an automobile window glass according to the invention will be described with reference to the drawings.
The method for removing a window glass for an automobile according to the present invention is a method that can be suitably used as a method for removing a side glass such as a rear side glass, although it can be used as a method for removing a windshield or a rear glass.
This is because the windshield and rear glass use so-called “laminated glass” in which two sheets of glass are bonded together with an adhesive, and the adhesive used in the glass when heated. This is because the tempered glass may be peeled off due to softening first, whereas “tempered glass” is used as the side glass, and there is no problem even if a little heat is applied.
Therefore, in the following description, the case where the method according to the present invention is applied to the side glass removing operation will be described as an example.

FIG. 1 is a view showing a state before the operation of the method according to the present invention (a state in which an inner paste is removed), in which (a) is a front view of the side glass and its periphery viewed from the inside of the automobile, and (b). Is a cross-sectional view taken along line AA.
Since there is no structure such as a dashboard around the side glass, as shown in FIG. 1, when the inner paste is removed, as shown in FIG. 1, the sheet metal part (vehicle body panel) (2) of the vehicle body to which the glass is adhered. Appears. A solid line represented by reference numeral (2a) in FIG. 1 (a) is an outline of a window frame formed by the end of the vehicle body panel (2).

  The vehicle body panel (2) is composed of an inner panel (21) and an outer panel (22) integrated by spot welding. As shown in FIG. 1 (b), the outer peripheral edge of the glass (1) and the outer panel ( 22) is provided with a mall (3). The mall (3) may be detachable or impossible.

Inside the glass (1) is a waterproof dam rubber (4), and there is an adhesive (5) between the molding (3) and the dam rubber (4). This adhesive (5) is a urethane-based adhesive that softens when heat is applied, and bonds the glass (1) to the vehicle body panel (2) (outer panel).
The dam rubber (4) is attached to the glass (1) with an adhesive tape, but is not directly attached to the vehicle body panel (2) (outer panel).

  In the method according to the present invention, as shown in FIG. 1, first, along the portion where the glass (1) of the vehicle body panel (2) is bonded from the inside of the automobile, the belt heater (6 ) Is installed (see FIG. 2).

FIG. 3 is a view showing an example of the belt-like heater (6), where (a) is a plan view and (b) and (c) are sectional views.
The belt-like heater (6) is formed by coating a wire (61) that generates heat when energized, such as a nichrome wire, with a coating material (62) having excellent heat resistance, and forming the belt-like heater (6). The wire rod (61) is connected to the power source via the lead wire (63).
FIG. 2 (b) shows a case where silicon rubber or fluoro rubber is used as the covering material (62), and FIG. 2 (c) shows a case where glass fiber is used as the covering material (62). Is shown.

FIG. 2 shows a state in which the belt-like heater (6) is installed along the glass bonding portion of the vehicle body panel (2) (that is, along the window frame (2a)), (a) is a front view, and (b) ) Is a sectional view taken along line AA.
The belt-like heater (6) is installed along the glass bonding portion of the vehicle body panel (2) by using a plurality of locking tools (7) arranged at appropriate intervals. As a locking tool (7), the clip marketed as a stationery may be used, and what is shown in FIG. 4 may be used.

Fig.4 (a) is sectional drawing of a locking tool (7), FIG.4 (b) is sectional drawing of the state which mounted | wore the locking tool (7) with the strip | belt-shaped heater (6).
The locking tool (7) includes a surrounding part (71) having a substantially rectangular cross section surrounding the belt-like heater (6) and a locking part that can be locked to the glass (1) side surface of the vehicle body panel (2). (72) is integrally formed of a metal spring material.

  A surrounding part (71) is arrange | positioned at the back side part (7a) arrange | positioned at the back side of a strip | belt-shaped heater (6), and a lower side, when attaching to the lower side of a window frame (refer FIG.2 (b)). The lower surface portion (7b), the front surface portion (7c) disposed on the front side, and the upper surface portion (7d) disposed on the upper side are integrally formed continuously in this order.

The front surface portion (7c) is recessed in a V shape toward the back surface portion (7a), and the apex of the recessed portion comes into contact with the surface of the belt-like heater (6).
The back surface part (7a) is formed shorter than the front surface part (7c), and a gap is formed between the back surface part (7d) and the top surface part (7d). The upper surface portion (7d) is formed longer than the lower surface portion (7b) and extends beyond the back surface portion (7a).
The extended end of the upper surface portion (7d) is bent downward and inward, and this bent portion constitutes the locking portion (72).

When the belt-like heater (6) is locked to the vehicle body panel (2) using the locking tool (7), first, as shown in FIG. 4 (b), the belt-like heater (6 ).
Next, by locking the locking portion (72) of the locking tool (7) to the glass side surface of the vehicle body panel (2) (outer panel), as shown in FIG. It can fix along the glass adhesion part of a vehicle body panel (2).
At this time, since the locking tool (7) is integrally formed from the spring material, the belt-like heater (6) is pressed tightly against the vehicle body panel (2).

  As shown in FIG. 2 (a), a plurality of locking devices (7) are attached to the belt heater (6) at appropriate intervals and locked to the vehicle body panel (2), as shown in FIG. 6) can be installed along the glass bonding portion of the vehicle body panel (2) (along the window frame).

However, the strip heater (6) has high flexibility in the thickness direction but low flexibility in the width direction. Therefore, in the installed state of FIG. 2 (a), the corner portion (corner portion) of the glass (window frame). ), The strip heater (6) is lifted.
FIG. 5 is a diagram in which the corner portion is viewed in the direction of arrow B in the installed state of FIG. 2 (a). The belt-shaped heater (6) is lifted and a gap is formed between the vehicle body panel (2). It shows a state.

  Even when the belt heater (6) is lifted at the corner (installed state in FIG. 2 (a)) and the belt heater (6) is energized to generate heat, the glass panel of the vehicle body panel (2) is bonded by heat conduction. Although heat spreads over the entire part, in the present invention, it is preferable to use a second locking tool having a shape different from that of the locking tool (7) in order to reliably heat the corner portion.

FIG. 6A is a cross-sectional view of the second locking tool (8), and FIG. 6B is a cross-sectional view of a state in which the belt-like heater (6) is mounted on the second locking tool (8). is there.
The second locking tool (8) includes a surrounding section (81) having a substantially square cross section surrounding the belt-like heater (6) and a locking section that can be locked to the glass side surface of the vehicle body panel (2). (82) are integrally formed of a metal spring material.

The second locking tool (8) is greatly different from the locking tool (7) described above in that the locking part (82) is inclined with respect to the surrounding part (81). Specifically, it is inclined about 30 to 50 °.
When the surrounding part (81) is attached to the upper side of the window frame (see FIG. 8C), the upper surface part (8a) disposed on the upper side of the belt-like heater (6) and the surface disposed on the front side The portion (8b), the lower surface portion (8c) disposed on the lower side, and the rear surface portion (8d) disposed on the rear side are integrally formed in this order.

  The upper surface part (8a) is formed shorter than the lower surface part (8c), and a gap is formed between the upper surface part (8d) and the back surface part (8d). Further, the back surface portion (8d) is bent outwardly into a U-shape and then further outwardly bent into a U-shape, and the portion bent into this U-shape is involved. The stop part (82) is comprised.

When the belt-like heater (6) is locked to the corner portion of the vehicle body panel (2) (window frame) using the second locking tool (8), first, as shown in FIG. The strip heater (6) is accommodated in the part (81).
Next, the locking portion (82) of the second locking tool (8) is placed on the glass of the vehicle body panel (2) (outer panel) at the corner of the glass (1), that is, the corner portion of the vehicle body panel (2). By locking to the side surface, the belt-like heater (6) can be fixed to the corner portion of the vehicle body panel (2) as shown in FIG.

FIG. 7 is a front view showing a state in which the second locking tool (8) is installed in three corner portions, and FIG. 8 (a) is a view showing a state in which the corner portions are viewed in the arrow B direction. 8B is a cross-sectional view of the arrow B portion, and FIG. 8C is a cross-sectional view taken along the line CC of FIG. 8A.
As described above, the strip heater (6) is in a raised state at the corner portion (corner portion) of the glass (window frame), but the second locking tool (8) is in relation to the surrounding portion (81). Since the locking part (82) is inclined, the raised belt-like heater (6) can be accommodated in the surrounding part (81).
Therefore, even at the corner of the glass where it is difficult to bring the belt heater into close contact with the vehicle body panel, the heat of the belt heater (6) is utilized by the heat conduction of the metal second locking tool (8). Can be transmitted to the body panel.

  Thus, after installing the strip heater (6) along the entire circumference of the glass bonding portion of the vehicle body panel using the latch (7) and the second latch (8), the strip heater ( By energizing 6) to generate heat, the glass bonding portion is heated to soften the adhesive (5) in the portion.

  Next, the glass (1) is removed from the vehicle body panel (2) by cutting the adhesive (5) with a blade. At this time, since the adhesive (5) is softened by heating, it is possible to easily and quickly perform the cutting operation with the blade.

A commercially available cutter knife may be used as the blade for cutting the adhesive (5), but it is preferable to use a dedicated cutting tool.
FIG. 9 is a view showing a dedicated cutting tool (9), where (a) is a plan view, (b) is a front view, and (c) is a right side view.
The cutting tool (9) has a rod-shaped handle portion (91) that a person can hold with both hands, and a blade portion (92) extending from the tip of the handle portion (91).
The blade portion (92) has a tip portion bent at a substantially right angle with respect to the handle portion (91). More specifically, after extending a predetermined length in the length direction of the handle portion (91), it is bent in a direction substantially perpendicular to the length direction of the handle portion (91). Here, the predetermined length is a length that does not cause the handle portion (91) to interfere with the locking tool (7) when cutting the adhesive (5) with at least the blade portion (92) (see FIG. 10).

FIG. 10 is a diagram showing a state where the adhesive (5) is cut using the cutting tool (9).
By using the special cutting tool (9), the blade part is parallel to the glass without causing the handle part to interfere with the vehicle body while holding the handle part with both hands in the adhesive cutting process. Can be moved.
Therefore, the softened adhesive can be cut easily and in a short time. The state after cutting the adhesive is shown in FIG.

Moreover, in this invention, it is preferable to use the glass pressing tool which presses a glass surface toward the exterior side (direction away from a vehicle body) in the cutting process of the adhesive agent with a cutter.
FIG. 12 is a view showing the glass pressing tool (10), in which (a) is a plan view of a frame that is one of the components of the pressing tool, (b) is a front view of the entire pressing tool, (c) is the sectional view on the AA line of (b), (d) is the sectional view on the BB line of (b).

  The glass pressing tool (10) includes a frame (101) formed in a straight line, left and right legs (102) attached to both ends of the frame (101) to hold the frame at a predetermined height, It is comprised from the adsorption | suction part (103) attached between the leg parts (102) on either side of a flame | frame.

The frame (101) is a member having a cross-sectional shape in which the center of the lower side of the rectangle is cut out, and a slit (101a) is formed on the upper surface thereof.
The lower ends of the left and right legs (102) are bent toward opposite sides (outside), and these bent portions can be locked to the glass side surface of the vehicle body panel (2). (102a) is formed. In addition, the upper end is formed with a flange portion (102b) that is locked to the inner lower end of the frame (101), and the leg portion (102) can be slid along the frame (101). ing.

The suction portion (103) includes a slide member (103a) movable along the frame (101), and a suction cup (103b) attached to the slide member (103a) so as to be adjustable in height and capable of being sucked to the glass surface. ).
The slide member (103a) is a U-shaped member facing upward in cross section, and is accommodated in the frame (101). Further, the screw rod (103c) penetrates the slide member (103a) in the vertical direction.
A knob (103d) is attached to the upper end of the screw rod (103c), and a suction cup (103b) is attached to the lower end. Further, a nut (103e) is screwed to the middle portion of the screw rod (103c) with its lower surface in contact with the slide member (103a).

FIG. 13: is a figure which shows the attachment state to the glass surface of a glass pressing tool (10).
As for the mounting method, from the inside of the automobile, the locking portions (102a) of the left and right legs (102) are locked to the glass side surface of the vehicle body panel (2), and then the knob (103d) is turned to turn the screw. The rod (103c) is screwed downward, and the suction cup (103b) of the suction portion (103) is pressed against the glass surface for suction.
As a result, a pressing force acts on the glass (1) on the outside side, that is, in a direction away from the vehicle body panel (2), so that the force required to cut the adhesive (5) by the blade is further reduced.

When the adhesive on one or two sides of the glass is cut, a gap is formed between the glass and the vehicle body panel, and further, the gap is widened by pressing the suction cup, so that the cutting is further facilitated.
For example, if the suction cup is pressed against the glass with only the left side and the lower side cut out of the four sides of the glass, the knife is not resistant even if the adhesive is not sufficiently softened, so that it can be easily cut.
When the car body and glass are attached, there is no room for the cutter to enter because there is no escape area for the adhesive when the cutter enters the adhesive. Cutting becomes easy.

  Since the leg (102) and the suction part (103) are slidable along the frame (101), the glass pressing tool (10) can move the leg (102) and the suction part ( 103) can be adjusted.

  The glass pressing tool (10) may be used before cutting the adhesive with a blade, or may be used after partially cutting, depending on the state of adhesion.

Hereinafter, the effect of the present invention will be made clearer by showing examples of the method for removing a window glass for automobiles according to the present invention. However, the present invention is not limited to the following examples.
(Example 1)
Using the method according to the present invention, the removal work of the side glass (about 20 cm wide × about 40 cm long) of the minicar was performed according to the following procedure.
After removing the inner paste, install the belt heater using the above-mentioned locking device and the second locking device along the part where the glass of the vehicle body panel is bonded from the inside of the car, and energize the belt heater The glass adhesion part was heated by generating heat.
As the belt-like heater, a glass fiber having a width of 20 mm × length of 1 m and power: 200 W / 1 m is used as a covering material (see FIGS. 3A and 3C), and the glass is sequentially applied to the right side, the lower side, and the left side. It was arranged in a substantially U shape so as to be along.
After heating (energization) for 20 minutes, the temperature of each part around the glass was measured and as shown in Table 1.

  Since the adhesive part was not exposed, the temperature could not be measured, but it seems that the temperature was higher than 72 ° C. near the heater of the vehicle body panel (inner panel).

Immediately after the temperature measurement, the adhesive cutting operation was started.
The cutting operation was performed as shown in FIG. 10 using the cutting tool (9) shown in FIG. The time required for cutting the heated portion (three sides) of the adhesive was about 4 minutes.
Subsequently, the glass pressing tool (10) shown in FIG. 12 was used to cut the remaining one side adhesive using the same cutting tool (9), and the glass was removed from the vehicle body panel. The time required for cutting was about 3 minutes.
The time required for installing the heater and pulling in the power supply was about 3 minutes, so when combined with the heating time, the total work time was about 30 minutes, but the net work time excluding the heating time was about 30 minutes. It was 10 minutes.

(Example 2)
The side glass (about 60 cm wide × about 40 cm long) on the opposite surface of the same vehicle as in Example 1 was removed.
The same belt-like heater as that of Example 1 was disposed as shown in FIG. 7, and then the glass-bonded portion of the vehicle body panel was heated by energizing the belt-like heater to generate heat.
When the temperature of each part was measured after heating (energization) for 30 minutes, the temperature at the center part of the heater surface was slightly higher (about 210 ° C.), but the other parts were not much different from the temperatures shown in Table 1. (± 0 to about + 2 ° C.).

Immediately after the temperature measurement, the adhesive (four sides) was cut using the same cutting tool as in Example 1. In addition, the glass pressing tool was not used.
The total time required for the work was about 40 minutes because the heating time was 10 minutes longer than that of Example 1 to heat the four sides, but the net work time excluding the heating time was about 10 minutes. .
In Example 2, the work could be performed smoothly without using a glass pressing tool, but this was because the temperature was relatively warm at about 20 ° C., and when working in a mid-winter environment. It seems necessary to use a glass pusher in place.

From the above examples, it was confirmed that according to the method according to the present invention, the working time can be greatly reduced as compared with the conventional method without heating.
Moreover, it is thought that the temperature of glass and a molding became low with respect to heater temperature is the effect which has not heated glass directly. In addition, when a heater is directly applied to the molding, it burns instantaneously, but such a problem does not occur in the method according to the present invention.

  The present invention is used for removing a window glass at the time of repairing a car body of an automobile, and can be suitably used for removing a relatively small window glass such as a rear side glass of a light car or a wagon car.
