Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glass repair tool used for repairing dents caused by flying stones on the surface of inorganic or organic glass (including laminated glass) for vehicles and buildings.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional glass repair tool M0 has a seal member 1 and a tube 5 connected to a suction pump (not shown).

The seal member 1, as shown in FIGS.
It is made of synthetic resin and has a cylindrical tubular portion 2 and a flange portion 3 which is disposed at the lower end of the tubular portion 2 and which is brought into close contact with the peripheral edge of the concave scratch B on the surface of the glass G. . In the flange portion 3, the adhesive 3b was applied to the back surface of the main body 3a.

The tube 5 was constructed by connecting a joint 5b to the end of a flexible main body 5a.

When using the glass repair tool M0, first, as shown in FIG.
The flange portion 3 of the seal member 1 is brought into close contact with the peripheral edge of the concave scratch B, and the filler R is filled into the cylindrical portion 2 of the seal member 1.

Then, the operation of the suction pump (not shown) is stopped, and the end of the tube 5 on the suction pump side is opened to the atmosphere. Then, since the space H between the filler R and the recess B in the tubular portion 2 is depressurized from the atmospheric pressure and gravity also acts, the filler R fits into the recess B. So that it will be filled.

After that, the seal member 1 is peeled off and the filler R
If the surface of the glass G is cured while being smoothed, the repair of the glass G can be completed.

[0009]

However, in the conventional glass repairing tool M0, since the tube 5 having a small inner diameter is directly connected to the tubular portion 2 of the seal member 1, the filler R in the tubular portion 2 is used. The air A in the space H between the dents B and
In some cases, the filler R was pushed up to the side of the tube body 5a when it escaped through.

Not only could the glass G not be repaired, but the tube 5 was rendered unusable.

Such a situation frequently occurs when the glass G is repaired, and usually 3 to 4 before the repair is completed.
It has always happened.

The present invention is intended to solve the above problems, and an object of the present invention is to provide a glass repairing tool capable of surely repairing a dented glass without moving the filler to the tube side. To do.

[0013]

A glass repairing tool according to the present invention comprises a cylindrical portion for repairing the glass surface by filling and curing a filler in the concave scratch formed on the glass surface, A seal member having a flange portion that is disposed at the end of the tubular portion and is brought into close contact with the peripheral edge of the scratch on the glass surface,
An attachment connected to the tubular portion, a tube connected to the attachment and connected to a suction pump,
A glass repairing tool comprising: a lower connection part, wherein the attachment has a lower connection part at a lower end, the lower connection part being fittable to the seal member tube part, and connectable to the sealing member tube part; And a cylindrical shape having an upper connecting portion that can be connected to each other, and prevents the filler from entering the tube during suction on the lower connecting side between the lower connecting portion and the upper connecting portion. As described above, it is possible to store the filler,
In addition, it is characterized in that a liquid storage chamber capable of returning the stored filler to the tubular portion by gravity is provided.

[0014] It is desirable that the liquid storage chamber gradually becomes larger in inner peripheral shape than the seal member cylinder portion as the distance from the lower connection portion increases. And in that case, the attachment is bent so as to intersect the axial direction of the lower connection portion and the upper connection portion, and as the liquid storage chamber,
It is desirable that the angle of the inner peripheral surface of the inner portion of the bent portion is larger than the angle of the inner peripheral surface of the outer portion of the bent portion with the axial direction of the lower connection portion as the center.

Alternatively, the attachment is arranged so that the lower connecting portion and the upper connecting portion intersect in the axial direction.
Bending, forming an outwardly swelling liquid storage concave portion on the inner peripheral surface of the inner portion of the bent portion, and parallel to the axial direction of the lower connection portion on the inner peripheral surface of the outer portion of the bent portion. Alternatively, the liquid storage chamber may be formed by the liquid storage recess and the guide surface.

[0016]

In the glass repair tool according to the present invention, when used, the flange portion of the seal member is brought into close contact with the concave edge of the glass, and then the cylindrical portion of the seal member is filled with the filler.
The lower connection portion of the attachment, which is connected to the tube, is connected to the tubular portion of the seal member. Then, when sucked, the air between the filler and the glass in the tubular portion is sucked and pushed up by the air, and the filler moves to the attachment. At that time, the filler is stored in the liquid storage chamber, so that the filler is prevented from entering the tube. Then stop the suction,
By utilizing gravity, the filler is returned to the inside of the seal member tube portion, and if the tube side is raised to atmospheric pressure or the like, the filler returned to the inside of the tube portion causes a gap between the filler and the glass in the tube portion. Due to the reduced pressure and gravity of the site, the concave scratch is filled.
Then, the seal member and the like are peeled off to cure the filler, and the surface of the filler can be smoothed to complete the repair.

Therefore, in the glass repair tool according to the present invention, it is possible to reliably repair the dents in the glass without moving the filler to the tube side.

If the liquid storage chamber of the attachment is gradually made larger in inner peripheral shape than the seal member tubular portion as it goes away from the lower connection portion of the attachment, suction after filling the seal member tubular portion with the filler is performed. At this time, even if the air in the space between the filler and the concave scratch in the tubular portion pushes the filler into the liquid storage chamber, the volume of the liquid storage chamber is large, so before the filler moves to the tube side. Since the air passes through the inside of the filler, the movement of the filler to the tube side can be prevented. Further, after suction, since the liquid storage chamber has a taper shape in which the inner peripheral shape is gradually made larger than the sealing member tubular portion as the distance from the lower connecting portion increases, the filler naturally fills the sealing member tubular portion by the action of gravity. It can be moved into the department. Therefore, it is possible to surely repair the glass scratches without moving the filler to the tube side.

Further, the attachment used at that time is bent so as to intersect the axial direction of the lower connecting portion and the upper connecting portion, and is bent around the axial direction of the lower connecting portion as a liquid storage chamber. The angle of the inner peripheral surface of the inner part of the part,
If it is configured to be larger than the angle of the inner peripheral surface of the outer portion of the bent portion, the following effects can be obtained.

That is, at the time of suction after filling the seal member cylinder portion with the filler, if the inner portion of the bent portion of the liquid storage chamber is arranged downward, the volume is large, so that the filler is stored. Easy to do. Then, after suction, if the attachment is rotated by 180 ° with respect to the seal member cylinder, the inside portion of the bent portion is located above, and the filler stored in that portion is outside the bent portion. Since the inner peripheral surface of the outer part that hangs down to the part side is not closer to the vertical direction than the inner peripheral surface of the bent inner part that is rotated by 180 °, it is possible to use the gravity to place it inside the tubular part of the seal member. It is easy to transfer the filler. Therefore, it is possible to smoothly store the filler in the liquid storage chamber and transfer it to the seal member tube portion, and improve the workability of the repair work.

Further, the attachment is bent so as to intersect the axial direction of the lower connecting portion and the upper connecting portion, and a liquid storage concave portion bulging outward is formed on the inner peripheral surface of the inner portion of the bent portion. Formed, on the inner peripheral surface of the outer part of the bent part,
When a guide surface parallel to the axial direction of the lower connection part is formed, and a liquid storage chamber is formed by the liquid storage recess and the guide surface, when the filler is sucked into the seal member tubular portion after suction, the liquid If the inner part of the bent part of the reservoir is placed below, the volume is large, so even if the amount of filler is large, there is no problem.
Can be stored in the liquid storage recess. Then, after suction, if the attachment is rotated 180 ° with respect to the seal member tubular portion, the guide surface of the outer portion of the bent portion is arranged below, and the guide surface is in the axial direction of the lower connection portion, that is, Since it is parallel to the axial direction of the seal member tubular portion, it becomes easy to transfer the filler into the tubular portion of the seal member by utilizing gravity. Therefore, it is possible to smoothly store a large amount of the filler in the liquid storage chamber and transfer it to the seal member tubular portion.

And

The attachment 7 can be manufactured by injection-molding a divided product which is divided into two parts at a site where the die can be easily removed, and joining the divided products using an adhesive. can do.

Explaining the mode of use of the glass repair tool M1 of the embodiment, first, as shown in FIG. 1, the adhesive 3b is used to apply the flange portion of the seal member 1 to the periphery of the concave scratch B of the glass G. 3, and the filler R is filled in the cylindrical portion 2 of the seal member 1.

Thereafter, as shown in FIG. 3, the lower connection portion 8 of the attachment 7 to which the joint 5b of the tube 5 is connected.
Is fitted into the tubular portion 2 of the seal member 1. At this time, the attachment 7 is arranged so that the liquid storage recess 12 of the liquid storage chamber 11 is located below the guide surface 13.

Then, a suction pump (not shown) connected to the tube 5 is operated. Then, as shown in FIGS. 3 and 7, the air A in the space H between the filler R in the tubular portion 2 and the recess B is sucked, and the filler R is moved along with the movement of the air A at that time. Moves from the tube portion 2 to the attachment 7. At this time, the lower connection portion 8 in the intermediate portion 10 of the attachment 7
On the side, since the liquid storage recess 12 of the liquid storage chamber 11 which is expanded and has a large internal space is formed, the filler R and the air A are separated, and the filler R is stored in the liquid storage recess 12. The Rukoto. Then, the filler R is stored in the liquid storage recess 12, so that the inside of the tubular portion 2 of the seal member 1 and the tube 5 are electrically connected to each other via the lower connection portion 8, the intermediate portion 10, and the upper connection portion 9 of the attachment 7. As a result, the pressure inside the tubular portion 2 is reduced.

Thereafter, as shown in FIG. 8, the seal member 1
The attachment 7 is rotated 180 ° with respect to the tubular portion 2. Then, parallel to the axial direction of the lower connecting portion 8, that is,
A guide surface 1 formed parallel to the tubular portion 2 of the seal member 1.
3 is disposed below, and the filler R stored in the liquid storage recess 12 moves to the guide surface 13 in the liquid storage chamber 11 so as to drop by the action of gravity, and further, the tubular portion 2 It moves to the inside and closes the tubular portion 2.

Thereafter, the operation of the suction pump (not shown) is stopped, and the end of the tube 5 on the suction pump side is opened to the atmosphere. Then, as shown in FIGS. 8 and 9, the space H between the filler R and the concave scratch B in the tubular portion 2 is depressurized from the atmospheric pressure, and the filler R is urged by the action of gravity. , So that it is filled in the concave scratch B.

Then, the sealing member 1 is peeled off together with the attachment 7 and the like, and the surface of the filler R is smoothed and cured, whereby the repair of the glass G can be completed.

Therefore, the glass repair tool M1 of the embodiment
Then, when the suction pump (not shown) is operated, as shown in FIG. 7, the filler R can be stored in the liquid storage recess 12 of the liquid storage chamber 11, and the filler R can be prevented from entering the tube 5. Also, after that, if the attachment 7 is rotated, the filler R can be returned to the inside of the tubular portion 2 of the seal member 1 by gravity. Therefore, the filler R can be repaired when the glass G is repaired.
The concave scratch B on the glass G can be reliably repaired without moving the glass to the tube 5 side.

In the above-described embodiment, the liquid storage chamber 11
Although it is shown that it is composed of the liquid storage recess 12 and the guide surface 13, the axial direction C between the lower connecting portion 8 and the upper connecting portion 9 is similar to the attachment 17 of the glass repair tool M2 shown in FIG.
1. C2 is bent so that it intersects at a crossing angle α of 150 °, and as the liquid storage chamber 21 becomes farther from the lower connecting portion 8, the inner peripheral shape is gradually increased from the sealing member tubular portion 2, and the lower connecting portion is formed. With the axial direction C1 of the part 8 as the center,
The large volume portion 22 and the small volume portion 23 are configured such that the angle β of the inner peripheral surface 22a of the inner portion of the bent portion is larger than the angle γ of the inner peripheral surface 23a of the outer portion of the bent portion. You may do it.

Also in this glass repair tool M2, when the suction pump (not shown) is operated, as shown in FIG.
The filler R can be stored in the large volume portion 22 of the above, and the invasion of the filler R into the tube 5 can be prevented.
When rotated by 0 °, the large volume portion 22 is located above, so that the stored filler R drips toward the small volume portion 23 side.
Further, since the inner peripheral surface 23a of the small volume portion 23 is closer to the vertical direction than the inner peripheral surface 22a of the large volume portion 22 in the state before being rotated by 180 °, the inner peripheral surface 23a of the small volume portion 23 passes through the seal. The filler R can be returned by gravity into the tubular portion 2 of the member 1. Therefore, the storage of the filler R in the liquid storage chamber 21 and the transfer to the seal member tubular portion 2 can be performed smoothly, and the workability of repair work can be improved.

By the way, in the case of forming the liquid storage recess 12 that bulges outward in the liquid storage chamber 11 as in the glass repair tool M1, the liquid storage recess 12 is larger than that in the case where the inner peripheral surface is linear. Since the volume of the recess 12 becomes large, when the suction pump (not shown) is operated, even if the amount of the filler R is large, it becomes difficult to transfer it to the taper pipe portion 14 on the upper connection portion 9 side in the intermediate portion 10 of the attachment 7. Further, the movement of the filler R to the tube 5 side can be further prevented.

In the above-described embodiment, the axial direction C1 between the lower connecting portion 8 and the upper connecting portion 9 of the attachments 7 and 17 is C1.
The crossing angle α of C2 is set to 150 °, but the crossing angle α of the attached metes 7 and 17 to bend is the angle of the surface of the glass G to be repaired or the cylindrical portion of the seal member 1 to be used with respect to the flange portion 3. Depending on the angle of 2
It is easy to store the filler R in the inside 21, and after that, the attachments 7 and 17 are attached to the sealing member tube portion 2 by 180 °.
The filler R may be appropriately set so that the filler R easily drips toward the seal member cylinder portion 2 side when rotated.

Even if the attachments 7 and 17 are not bent, if the liquid storage chambers 11 and 21 are formed to have a shape in which the inner peripheral shape is gradually increased from the sealing member tubular portion 2 as the liquid collecting chambers 11 and 21 move away from the lower connecting portion 8, suction During operation of the pump, even if the air A in the space H between the filler R in the tapered cylindrical portion 2 and the recess B pushes the filler R to the liquid storage chambers 11 and 21,
Since the volume of the liquid storage chambers 11 and 21 is large, the air A passes through the filler R before the filler R moves to the tube 5 side, and the movement of the filler R to the tube 5 side is prevented. Can be prevented. Further, after the suction, the liquid storage chambers 11 and 21 have a tapered shape in which the inner peripheral shape gradually increases from the sealing member tubular portion 2 as the distance from the lower connecting portion 8 increases. The seal member 1 can be naturally moved into the tubular portion 2.
