Description

Bulletproof glass pane for motor vehicle

Technical Field

The invention relates to the field of glass processing equipment, in particular to a bulletproof glass pane for a motor vehicle.

Background

The bulletproof glass pane has the structure of a composite glass pane comprising a plurality of glass panes and an interposed composite layer of plastic material, for example polyurethane. At the peripheral edge or circumference of the prior art bullet-proof glass panel there is a protrusion with an inner step. Inside the projection, a perimeter reinforcement is integrated as part of the composite material, having a rectangular cross-section, and is arranged on the surface of the projection facing the interior of the vehicle. The edge reinforcement is formed as a welded or stamped frame and is constructed, for example, from metal or stainless steel. The metal edge reinforcement is subject to relatively high temperature-dependent positional variations, which may even lead to cracking, splitting or other damage of the bulletproof glass pane in the edge region.

The object of the present invention is to overcome the above-mentioned drawbacks of the prior art and to provide a bulletproof glass pane for motor vehicles which is suitable for preventing damage due to temperature fluctuations.

The technical scheme of the invention is as follows: comprising a plurality of panes and layers of glass, ceramic or plastic material, a composite material as layers bonded together at their interfaces, and an edge reinforcement extending at the circumference of the bulletproof glass pane, the edge reinforcement comprising at least two or more reinforcement members, which reinforcement members are in loose mutual engagement; each end of two adjacent and assembled reinforcing members of the edge reinforcement being engaged with each other in a manner movable relative to each other and overlapping each other; in the adjacent end and the fitting end, an end portion of one reinforcement member is provided with at least one receiving portion, and an end portion of the other reinforcement member is provided with at least one protruding portion that is fitted with the receiving portion, the receiving portion or the receiving portion and the protruding portion or the protruding portion having matching tapered structures.

Wherein each end of two adjacent and assembled stiffening members engage each other in a tongue and groove system, wherein the end of one stiffening member has at least one groove and the end of the other stiffening member has at least one groove; the forcing member has at least one tongue, which fits into the groove.

One stiffening member of the rim stiffener is provided with at least one protrusion or at least one tongue and/or with at least one receiving portion or at least one groove at each end thereof.

The interlocking ends of two adjacent stiffeners of the edge stiffener have facing, exposed planar abutment surfaces extending parallel to the cross-sectional plane of the stiffener or edge stiffener and abutment; when two adjacent reinforcing members are fully engaged, they oppose each other.

The plurality of glass panes are arranged in layers with interposed composite layers, wherein at least one outer, first glass pane, a second glass pane arranged at the inner side next to the outer glass pane, and a third glass pane arranged on the outer glass pane. And e, which is arranged next to the second glass pane, wherein the first glass pane, which is located outside the edge of the bulletproof glass pane, protrudes above the second glass pane and the third glass pane, which is located at the edge of the bulletproof glass pane, protrudes above the second glass pane, so that a groove is formed between the outside, the first glass pane and the third glass pane, wherein the edge reinforcement extends into the groove in such a way that the third glass pane overlaps the edge reinforcement.

The invention has the beneficial effects that: which contributes to simplifying the manufacture or installation of a bulletproof glass window with edge reinforcement.

Detailed Description

In fig. 1, a bullet-proof glass pane for a motor vehicle has a laminated or laminated outer glass pane 1, a central glass panel 3 and an inner glass pane 5. Wherein the inner glass pane 5 is arranged towards the vehicle interior and the outer glass pane 1 is arranged towards the vehicle exterior and the centre glass. The central glass panel 3 is arranged between the outer glass pane 1 and the inner glass pane 5. The left side of the outer glass pane 1 is the outer, representing the side of the vehicle facing the impact. The polyurethane layer 2 extends between the outer glass panel 1 and the central glass panel 3, forming a composite between the outer glass panel 1 and the central glass panel 3. The polyurethane layer 2 or polyurethane foil has the same contour and extension as the outer glass pane 1. For example, an additional composite layer of polyurethane 4 or polyvinyl butyral (PVB) is formed between the central glass pane 3 and the inner glass pane 5, which in turn forms a fixing composite between the central glass pane 3 and the inner glass pane 5. The polyurethane layer 4 has the same ductility as the adjacent surface of the central glass panel 3. The outer glass pane 1 protrudes above the further

central glass panels

3 and 5 in a bulge 8 at the edge of the shown bulletproof glass pane, whereby a step or step with respect to the central glass panel 3 and the inner glass pane 5 is formed at the end face or peripheral surface. On the surface 10 of the polyurethane layer 2 facing inwards in the region of the bulges 8, an edge reinforcement 6 is mounted, which edge reinforcement 6 can consist of stainless steel, for example, which at least partially surrounds the bulletproof glass pane in the form of a frame, and at the same time H forms a fixed composite with the outer glass pane 1 via the polyurethane layer 2. On the end face 9 of the bullet-proof glass pane or on the end face of the projection 8, the outer glass pane 1, the polyurethane layer 2 and the edge reinforcement 6 are flush with one another. The edge stiffener 6 has a rectangular cross-section. The projection 8 formed by the edge reinforcement 6, the outer glass panel 1 and the interposed composite layer 2 is thus supported in the frame 14 of the motor vehicle. As a fold line and extends in the region of the roof of the motor vehicle. The protrusions 8 of the bullet-proof glass pane extend into the frame 14. The side window shown is thus rolled up and the window is closed. In the stepped region of the shown bullet-proof glass pane the inner glass pane 5 protrudes above the central glass pane 3, so that a groove 12 or a groove or a receiving portion is formed in the region between the inner glass pane 5, the central glass pane 3, which groove or receiving portion is flush with the polyester. An end polyurethane layer 4 and a continuous polyurethane layer 2. The edge stiffener 6 extends into the recess 12 and abuts against the end face of the centre glass pane 3 in a near butt joint engagement. At the end faces, the central glass pane 5 is provided with a seal 7, for example of polyurethane, which also fills or seals the cavity 11 in the groove 12 between the adjacent surfaces of the edge reinforcement 6, the central glass pane 3 and the polyurethane layer 4-or bottom 1-. The inner glass pane 5 and the polyurethane layer 2 of the recess 12 are within the recess 12. The three

stiffeners

2, 3, 4 of the edge stiffener 6 have a strip-like and relatively elongated structure and all have substantially the same rectangular cross-section when viewed in cross-section, for example when viewed in cross-section at a mid-position of the

stiffeners

2, 3, 4. When the three reinforcing

members

2, 3 and 4 shown are assembled, the result is a frame-like edge reinforcement 6 on three sides of the bullet-proof glass pane. The reinforcing

members

2, 3 and 4 may be manufactured by punching out a punched plate.
