According to another aspect, the present invention provides a method for repairing damage to a window glass, wherein a pumping device (preferably a single pump) is used for: i) providing a means for securing a repairing device to the vehicle Suction on the glazing; and ii) providing a pressure cycle through the device in a repaired area.

According to still another aspect, the present invention provides a window glass repairing apparatus, comprising: a connecting means for connecting a pump device, and a fluid path connecting the connecting means and a holding area to apply suction Fixing the device on the window glass, and having a one-way check valve for maintaining the vacuum of the holding area; the vacuum can be released when the separation pressure relief valve provided on the device is activated, and wherein the device is provided There is a means of providing positive pressure and/or vacuum (suction) in a repaired area.

In accordance with this aspect, preferably, the apparatus is provided with means for providing positive pressure and vacuum (suction) in the repaired area.

According to still another aspect, the present invention provides a method for repairing damage to a window glass, wherein a power gas pumping device is used to provide a pressure cycle in a repaired area via a repairing device fixed to the window glass. (The forward pressure alternates with the vacuum suction).

It is beneficial to control the pressure cycle of the pump device by a control means.

Preferably, after the repair fluid is delivered to the repaired area, a plurality of cycles of pressure and vacuum suction are applied.

Referring to the drawings, a window glass repairing device 1 includes a body 2 on which an upper cover 3 is provided with a fixing bolt 4. The upper cover 3 and the body 2 are molded in a plastic material. Figures 1 and 2 show a repair resin delivery piston 5 positioned in a receiving tube (or interface) 6, the mode of operation of which will be described in more detail below. The resin piston 5 is provided with a rupturable repair resin bottle or capsule. Also shown is a vacuum/pressure connector 27 for connecting a single gas line to deliver a suction and/or gas forward pressure generated by a vacuum/pressure pump remote from the apparatus 1 to the apparatus.

Figure 1 shows the upper cover 3 positioned in the body 2. The third view is a corresponding view after the upper cover 3 and the resin piston 5 are removed. It can be seen that a vacuum/pressure connector 27 is coupled to a manifold 7 to deliver a vacuum negative pressure or pressure to the separation defined area on the underside of the device via the manifold branches 8, 9. Please refer to Figure 4, which shows the underside of the unit. The device is pressed against the surface of the window glass to be repaired. An outer annular suction region 10 is disposed between the inner ring rib 19 and the outer ring rib 20. The vacuum is supplied to the holding area vacuum 埠 12 via the check valve 17 to apply suction, so that the apparatus 1 can be fixed to the window glass. A pressure relief 连通 13 in communication with the pressure relief valve 16 bleeds the suction of the outer annular suction region 10. The inner ring rib 19 and the outer ring rib 20 are embossed from the lower plane of the device for contacting the window glass while keeping the lower plane of the device slightly spaced from the surface of the window glass. Thus, the repaired area and the suction area are defined in the space immediately below the lower side of the apparatus.

The vacuum/applied pressure is delivered to the outer annular suction zone 10 via a manifold 9 of the manifold joint, the one-way check valve 17 being provided in the manifold 9. The vacuum/applied pressure is also delivered to the inner repair region 18 via the manifold 8 of the manifold joint and delivered to the interior region of the repaired region via a manifold joint.

The pressure relief valve 13 is in communication with the pressure relief valve 16 (which may, for example, include a pressure relief nozzle). The pressure relief 13 is activated via a pressure relief activation button 21 pivoted to the exterior of the device. The pressure relief start button 21 is pivoted on the pivot structure, and the inclined wedge action portion 21a of the pressure relief start button 21 acts on the pressure relief actuator of the pressure relief valve.

The annular casing forming the resin piston interface is internally provided with a spike 11 for piercing the resin capsule contained in the cavity of the piston 5. After the capsule is pierced, the liquid repair resin flows down the length of the spike 11 and flows to the resin crucible 15 and the repaired region 18 via the flange 11a and the conduit 6a.

The above is the main component of the device, which is relatively inexpensive, easy to manufacture, and because the body and the upper cover are made of plastic material, not only maintenance-free, but also can be regarded as disposable parts.

The device is coupled to a gas pump 22 and a programmable controller 23 when in use. Figure 8 is a system diagram of this combination. The gas pump 22 has a vacuum (suction) 埠 24 and a pressure 埠 25.

In operation, a single gas line of the control valve unit 28 is coupled to the line joint connector 27. The control valve unit 28, under the operation of the controller, requires the gas line to deliver suction (vacuum) or forward pressure. A holding vacuum is first applied via the check valve 17, and this is established in the outer annular suction region 10. The purpose of the check valve 17 is to ensure that the vacuum does not leak unless the pressure relief valve 16 is activated. Vacuum is also applied to the damaged central internal repair region 18 via the manifold whereby the damaged region is degassed prior to application of the resin.

Then, the resin is applied in the same manner as in the previous case, that is, by pushing the piston 5 down, the resin capsule is pierced at the sharp needle 11 in the central vertical tube of the accommodating tube 6, so that the resin flows in the passage inside the body. The resin crucible 15 flows to the damaged area to fill the breakage.

The pump is typically operated in suction mode at this point to degas the resin and introduce it into the repaired area.

Then, the pump applies pressure to the damaged glass and the filled resin material by applying vacuum and forward pressure to the circulating wheel, and the mode of the circulating wheel can be set according to the best result obtained by trial and error. This ensures that the resin completely fills the break and that the resin is degassed to the maximum extent. The preferred cycle wheel mode will be described below. The power gas pump can be used to provide sufficient forward pressure and vacuum pressure for each part of the cycle for more than 30 seconds.

During the positive and negative pressure cycle, the device is firmly adsorbed to the window glass via vacuum pressure previously applied to the outer annular suction region 10.

After the operation is completed, the pressure relief start button 21 can be operated to release the pressure relief valve 16 to remove the device. The gas pump 22 can then be turned off.

Typically, the application of pressure and the overall operating cycle are controlled by a programmed controller that sets the length and operation of each positive and negative pressure during the operating cycle.

The standard procedure cycle is as follows: Vacuum = 22 in Hg Pressure = 25 psi Preliminary / Drying Stage: Vacuum - 180 seconds Repair Phase: Initial Vacuum = 30 seconds Breaking Capsule = 15 seconds Initial Pressure = 60 seconds Fast Procedure Phase 1 Vacuum #1=30 Second pressure #1=30 seconds Phase 2 Vacuum #2=30 seconds Pressure #2=30 seconds Stage 3 Vacuum #3=30 seconds Pressure #3=30 seconds Stage 4 Vacuum #4=30 seconds Pressure #4=30 seconds Stage 5 vacuum #5=30 seconds pressure #5=30 seconds phase 6 vacuum #6=30 seconds pressure #6=45 seconds

It should be understood that the features of the device 1 and the cycle of operation cycle are only preferred, and are not essential elements of the present invention. For example, other fluid paths and manifold configurations may also be used in the practice of the invention. The present invention is superior to the previous case in that an automated pressure cycle can be achieved without substantial user intervention. In the illustrated embodiment, the need for user intervention is limited to pushing the piston. Those skilled in the art should be aware that this step can also be implemented in an automated manner.

The application of this pressure can be supplied by a single pump, or multiple separate pumps can be used. The former is better than the former, but the latter is still superior to the previous case with its automation and control.
