10 plate-shaped element with arranged on an element edge profile part

The invention relates to a plate-shaped element, in particular glass pane for a motor vehicle window, having arranged on an element edge profile part, which has at least one point of its free surface at least one holding member 15, with the respective at least one functional part, such as roof trim and / or trim strip and / or Sealing lip or the like, is connectable.

It is known, the element edges, in particular the edges of in openings of

20 glass car bodies to be used, to be surrounded with more or less soft elastic frame, which extends both to the edges of the

Cling glass as well as to the edges of the body opening and thus can simultaneously perform a holding function as well as a sealing function. Before the glass pane can be inserted into a body opening, it requires the equipment of the glass pane, or of the corresponding plate-shaped element, with the profile part arranged at the edge of the element. For this purpose assembly operations are necessary. The equipped with the profile part plate-shaped element, in particular the glass, can then be handled as a unit and installed in the body. For this purpose, mostly adhesive bonds are used. 0

The plate-shaped elements, in particular glass panes for motor vehicle windows, are often additionally provided with functional parts, such as roof strips and / or trim strips and / or sealing lips, at their element edges or pane edges. equipped, which are suitably held on the element edge or disk edge arranged profile part.

It is known, for example, trim to equip with connecting elements, which then in turn is to connect with the profile parts on the edge of a plate-shaped element, in particular a glass pane.

In the case of elastically deformable profile parts, however, a holding function of correspondingly held connecting elements is only possible to a limited extent, because the regions of the less dimensionally stable profile part which hold a connecting element can deform under mechanical stresses in such a way that the holding function is no longer fulfilled. The connecting elements and thus the functional parts held by them can be detached from the profile parts located at the element edge or edge of the glass pane.

Adhesion of the connecting elements with predetermined surface areas of the plate element or the glass pane would advantageously increase the mechanical strength of the connecting elements, in particular when hardening adhesives are used. However, a bond has the disadvantage that they disassemble all arranged on the plate-shaped element or the glass pane components, functional parts and the like, for the purpose of carrying out repair work and in particular of recycling measures considerably more difficult and expensive.

The invention has for its object to provide a plate-shaped element, preferably a glass pane for a motor vehicle window, with all functional parts required for installation in the motor vehicle and the visual appearance on the motor vehicle as a unit manageable during installation and removal.

This object is achieved by the features of claim 1. Further developments of the solution according to the invention are specified in claims 2 to 11. The object is achieved by the features of claim 12. Further developments and particularly advantageous embodiments of the procedural solution of the problem are specified in claims 13 to 17.

The plate-shaped element, in particular a glass pane for a motor vehicle window, with arranged on an element edge profile part having at least one point of its free surface at least one holding member with which a functional part is connectable, according to the invention is characterized in that the profile part together with each Holding member is integrated in a present as encapsulation of the element edge integral molded part made of dimensionally stable and thus relatively hard material.

The plate-shaped element, in particular glass pane for a motor vehicle window, forms after the injection molding with the profile part a manageable unit, wherein the fact that the profiled part with molded or molded holding members are relatively dimensionally stable and hard due to the material used and are thus suitable holding functions for Roof strips, moldings, sealing lips or the like to fulfill functional parts.

The relatively hard and therefore dimensionally stable holding members are relatively easy to produce at the same time by encapsulation of the element edge with the profile part. In a suitable injection mold, a glass sheet can be inserted and overmolded. ^"

In this case, each holding member may be a survey of the profile part. The survey could be formed as ribs, strips or the like elongated shaped, strand-like projections or longitudinal parts. However, it is also possible to form each survey as a button, pin or the like point part, with multiple point parts can be arranged side by side or one behind the other in a row. Of course, a combination of longitudinal parts and point parts as survey on a profile part is possible. Conversely, not every holding member must necessarily be formed as a survey. It is also possible to form a retaining member in the form of a depression on the profile part. The injection molding process for encapsulation of the element edge with a profile part offers all the possibilities of training holding members on the profile part.

If a survey is used as a holding member, then it may be provided with at least one retaining groove or the like groove-like depression, with the projections of connecting elements of the functional parts are connectable. These fasteners may be parts of the functional parts, i. H. Function part and connecting element may also be integrally formed. The functional parts can be z. B. be equipped with elastically deformable projections, which can be brought into engagement with the retaining grooves, depressions or similar formations on the holding members of the profile parts. Snap or locking connections are particularly expedient and with particular advantage is provided that each connecting element is designed as a terminal with resiliently deflectable locking members.

It is particularly advantageous that each functional element together with the connecting elements located thereon can be formed into a preassembled mounting unit. This mounting unit can be readily connected to the plate-shaped element, or the glass pane, characterized in that it is pressed and latched with its connecting elements on the holding members of the profiled part arranged on the glass pane. Of course, it is also possible to form the preassembled assembly unit of functional elements with the connecting elements located thereon in such a way that it can be inserted into an injection mold for the molding of the profile part of dimensionally stable material to the element edge. In the encapsulation of the element edge with the dimensionally stable and relatively hard material then the profile part is formed, which has at the same time connected to the corresponding projections of the connecting elements of the preassembled mounting unit by molding, injection, etc.

After opening the mold as soon as the encapsulation has cured, a finished disc unit can be removed with functional parts on the element edge and optionally be supplied to the installation in a motor vehicle window of a motor vehicle body.

Thus, the overmolded profile parts after installation of the equipped with the profile parts disc unit in a body opening as optimal as possible

Can fulfill sealing functions, is provided according to a development that in at least a portion of a predetermined side region of the first

Profile part in each case at least one second profile part is arranged with respect to the material of the first profile part less dimensionally stable material. This second profile part, which is arranged in predetermined side regions of the first profile part made of hard and therefore dimensionally stable material, can cling to body parts in the vicinity of the installed disk unit due to its relatively soft elastic properties and thus optimally fulfill sealing functions. Also, the second profile part may be molded onto the disk unit, wherein it is particularly advantageous with an overmolding of the first profile part.

Preferably, the relatively dimensionally stable material for the first profile part is an elastomer, such as PVC or TPE, having a hardness of about 30 to 40 Shore D.

In contrast, an elastomer, such as PVC or TPE, having a hardness of about 50 to 90 Shore A is expedient for the over-molded second profile part.

On a profile part and various functional elements can be present next to each other or combined.

When carrying out a method for producing a plate-like element, in particular a glass pane for a motor vehicle window, as specified in the claims 1 to 11, the procedure according to the invention is that a plate-shaped element, in particular a glass pane of a vehicle glazing, in a lower shell of a closing mold an injection molding machine is inserted. Then, the lower shell is closed by placing an upper shell to an injection mold. In the given cavity, the dimensionally stable, relatively hard material, in particular a plastic such as TPE, pressed with a hardness of about 30 to 40 Shore D, creating a profile part as Encapsulation of the edge of the inserted element, the glass pane, is formed.

Subsequently, the injection mold is opened by removing the upper shell as soon as the pressed-in material has hardened. However, then no

Demoulding, as in conventional injection molding operations, but it is rather by

Attaching a second upper shell to the lower shell, in which the glass pane with the overmolded profile part is still, closed again to the injection mold. The second cavity, which is now defined by the second upper shell, becomes with another less dimensionally stable material, for example TPE, with a hardness of approximately

50 to 90 Shore A pressed. As a result, the profiled part still in the mold is overmolded with the second profiled part made of softer material.

Subsequently, the injection mold can be opened and the framed with the enclosure formed by encapsulation and overmolding framed glass and removed for further processing or use.

Before the injection mold is closed in order to produce an encapsulation of an inserted glass, it is particularly advantageous to place a preassembled assembly unit of functional elements and connecting elements arranged thereon in the upper shell of the still open injection mold, wherein the holding parts of the profiled part forming during encapsulation of the element edge are mounted Connecting elements of the functional elements form a positive connection. Of course, it is also possible to remove the element or the glass pane with the overmolded profile parts of the injection mold and to supply a mounting station, in which corresponding functional elements are set by means of the associated connecting elements to the holding members of the profile parts. Such an assembly may, for. B. also be executed by industrial robots.

With particular advantage, the respective lower shell after inserting the plate-like element, in particular the glass, gradually, z. B. about 90 °, are rotated in the predetermined closed position in front of the first upper shell. It is Z. Example, possible to arrange a plurality of lower shells on a turntable and successively past in provided with shells spray heads of arranged on the periphery of the turntable extruders in clocked steps. So z. B. two subshells offset by 180 ° to each other in a forming head are combined, which then cyclically in steps of z. B. is rotated about 90 °. Two injection molding machines or extruders, each for the different materials and each equipped with the associated upper shells, then stand together so that the open sides of the upper shells face each other. In the middle between the upper shells is the turntable with the forming of the two lower shells forming head, which is practically a central form. The manufacturing method for edging the edge of the element with cyclic rotation steps has the advantage that there are always several elements or glass panes on the turntable and thus successively an insertion station for pre-assembled functional parts, the Umspritzstation for the profile part, a waiting and cooling station, a removal station and if necessary, go through the overmolding station for the second profile part. The removal station can also be the station for inserting a new glass pane and a new preassembled assembly unit.

The insertion and removal of the items and the finished disc units can machine z. B. be carried out with corresponding suction cups on hoists within a production line or a transport line.

Embodiments of the invention, from which further inventive features result, are shown in the drawing. Show it:

Fig. 1 shows a partial section of a first portion of the Rand¬ area of a glued into a body windshield unit made of glass and circumferential

Surrounding consisting of a profile part with functional parts held on it, and 2 shows a sectional view of a second section of an edge region of a pane unit glued into a body made of glass pane and surrounding skirting from a first profile part with overmolded second profile part and mounting unit arranged on the first profile part of a functional element with connecting element in the form of a clamp located thereon ,

In Fig. 1 is a sectional view is represented by a part of an opening bounded by flanges 1 in a vehicle body. This bounded by the flanges 1 opening is closed by a plate-shaped element 2, which is present in the form of a glass plate 3 in this embodiment. On the element 2, or the glass sheet 3, a profile part 4 is arranged, which has on its free surface 5, two holding members 6 and 7, with each of which a functional part 8 and 9 is connected. The functional parts 8 and 9 are designed here as a decorative strip. The present as a decorative strip functional part 9 is also additionally combined with a sealing lip 10.

The profile part 4 is integrated together with each holding member 6, 7 in an overmolding of the element edge 11 of the element 2 and the edge of the glass sheet 3 present integral molding of dimensionally stable and thus relatively hard material. The seated on the element edge 11, and the edge of the glass pane 3 profile part 4 surrounds the element edge 11 as shown, so that the profile part 4 is relatively firmly on the element 2 and on the glass pane 3 sits.

The adhesive bead 12 is applied to the prepared for installation unit of plate-shaped element with profile part 4 and functional parts 8 and 9, held in the body opening and pressed against the flanges 1. Not yet cured adhesive is flattened until the provided on the profile part 4, indicated by dashed lines spacer 13 touches him facing the body flange 1. This ensures that a predetermined distance between the body flange 1 and the glass pane 3 or the plate-shaped element 2 is maintained.

This distance is also important insofar as it ensures the correct fit of the sealing lip 10 in the body opening.

Each holding member 6 and 7 is a survey 14 and 15 of the profile part 4, wherein each elevation 14, 15 is formed as a strip or the like longitudinal part.

The second profile part 22 is an overmolding of the profile part. 4

FIG. 2 shows a sectional view similar to FIG. 1, but in another edge region of the plate-shaped element 2, which here again is in the form of a glass pane 3. In this embodiment, the profile part 4 is again an encapsulation of the element edge 11 of a dimensionally stable and thus relatively hard material, such as TPE, having a hardness of about 30 to 40 Shore D. The profile part 4 has on its side facing away from the element edge 11 page or Free surface, a holding member 6 ^' , whose free edge is formed as a mushroom-like thickening 23 in cross section. On this mushroom-like thickening 23 of the clamping foot 24 of a connecting element 18 ^{'can be} latched, with its resiliently deflectable latching members 20 ^" and 21" here also as a trim strip present functional element 8 ^{' can be} latched.

With 22 ^' and 22 ^" second profile parts are designated, which are again over-molding of the profile part 4. The over-molded profile parts 22 ^' and 22 ^" consist of a less dimensionally stable material, such as an elastomer, for. As PVC or TPE, with a hardness of about 50 to 90 Shore A.

In both embodiments according to FIGS. 1 and 2, the profile part 4 is integrated together with each holding member 6, 7 and 6 ^' in a present as encapsulation of the element edge 11 integral molding of dimensionally stable and thus relatively hard material. This is advantageous for recycling measures, since a unit made of plastic parts can be removed from the plate-shaped element, or the glass pane 3, and glass and plastic can then be supplied to separate disposal.
