Description

DESCRIPTION

The present invention relates to a built-in window for automobiles and to a Method for their direct and reversible connection to the body of the motor vehicle.

Wl / As is well known, the permanently mounted windows of motor vehicles are currently under the body of the vehicle Intermediate layer of a seal made of elastomeric material, which is provided with a perimetral lip, which is intended to be astride the projecting frame engaging the receiving opening the disc includes.

Since this known connection system is mechanical, has it has the advantage of reversibility, i.e. it enables the direct dismantling of the Seheibe without special additional ones Working, however, it has the serious disadvantage that it requires complicated manual assembly interventions since this takes place according to the known system with the rope, by means of which the previously arranged on the disc Seal is deformed in order to - thanks to a pressure exerted simultaneously on the disc - astride the To arrange frame.

Except that these manual activities are cumbersome and of are indefinite because the assembly time depends on the Skill of the worker depends, so can they are in no way automated, in particular they cannot be carried out by robotic systems, which

as is well known, more and more in the large series productions can be used.

With the intention of eliminating this serious drawback, assembly systems based on chemical Welding (gluing) are based, proposed, but an assembly carried out in this way is not reversible and the assembly time is indefinite as it depends on parameters that are too easily changeable.

The main aim of the present invention is to eliminate these drawbacks. So is an important one The aim of the present invention is to provide windows for motor vehicles that are mechanically and reversibly at the The body of the motor vehicle can be attached in a significantly simplified manner, including a clear A certain amount of time is required and, in particular, the use of automatic systems is advantageous Robot systems is possible.

In particular, an object of the present invention is to provide a disk that prepares in a manner is that it is connected to the body of the motor vehicle in the course of a simple arrangement and application of pressure which activities outside the body can be determined by relatively simply constructed robot systems can be carried out.

To achieve these important goals and other goals, refer to the detailed description below

the present invention is based on that in the preceding laid-open specification no. DE 3337728 of same applicant described method for adhesive Pressing rubber on a pane of glass, by means of which a pane is obtained, on which a perimetrical one is tightly attached Rubber seal stuck; identifies the connection resulting from the application of the named method due to the mutual penetration of adhesive layers with one another, with the rubber and the pane, so that the connection between the rubber seal and the washer against mechanical loads and chemical-physical Influences as well as the effects of aging is insensitive.

In the aforementioned method, the chemical-molecular adhesion of the rubber to the window during the dimensional shaping of the rubber and its simultaneous transfer from the plastic phase to the elastic phase (pressing and vulcanizing) is generated and according to the invention is during the aforementioned phases the dimensional shaping and the transfer phase into the rubber by co-pressing a variety of inserts used, which are provided with elastically yielding retaining organs, which after removal from the mold The seal protrudes from the perimetral periphery of the disc, which is in the support frame provided on the body is used. The frame, in turn, carries a corresponding number of seats, which are intended to to accommodate the holding organs, which when a corresponding pressure is exerted from the outside on the previously

arranged disc that the holding members and the seats in question are flush with each other, snap into the seats.

Accordingly, a window according to the invention for motor vehicles is characterized in that it has a Has elastomeric perimetric seal that adheres to or tightly adheres to the disc is connected, preferably by chemical-molecular adhesion, which occurs during the dimensional formation of the Rubbers and the simultaneous transfer of the same from the plastic phase to the elastic phase is, wherein the seal has a plurality of organs for elastic support, which protrude from the seal, in which they are embedded by being pressed and made to adhere and serve by snapping them into place with a corresponding number of prepared on the body frame encompassing the window opening Sitting, cooperating.

Preferably, the inserts forming the holding members or at least the inserts are pressed into the seal embedded part made of polymer material, preferably of that known under the trade name "NYLON" Polymer material containing inert glass fibers, carbon fibers or aramid fibers.

The embedded part of the insert and the protruding part that forms the elastically yielding retaining element, can be integrally formed or they can

- ic -

be present separately and mechanically connected to one another, for example by means of an extension and a corresponding seat, which are threaded so that in the event of breakage or damage the holding member can be easily replaced.

The elastically naohgibige holding member is advantageously from a fork with parallel prongs, each of which has an end tooth with an outside undercut is provided to snap into place on the edge of the to intervene on the body provided seat, further according to the invention according to the arrangement of the disc the use of a retaining element between the prongs is provided in order to prevent them from being compressed for safety reasons and consequently to prevent the holding member from accidentally slipping out of its seat. The holding elements can be provided individually for each holding member, but they exist in a very advantageous manner from a continuous, rigid on the inside Cover strip or trim strip provided rib so that the strip can be easily snapped into place can; this rib thus fulfills both the function of a safety lock for the holding members of the disc as also that of a holder and support for the said strip or cover.

Further features and advantages are the following detailed description with reference to the accompanying drawings, which explain the invention by way of example and without limitation

In Fig. 1, 10 is the disc and 11 is the perimetral seal made of elastomeric material, which was previously and closely connected to the disc,

This connection, which can be made in any way, is preferably carried out using the rubber-disc adhesive method, which is described in the above-mentioned disclosure no. DE 3337728 of the applicant. This method is based on the creation of a chemical-molecular adhesion of the rubber to the window during the pressing phase i.e. during the dimensional formation of the rubber and its simultaneous transfer from the plastic Phase into the elastic phase.

According to the invention, during the said pressing phase in the rubber of the seal 11 by pressing and adhesion a plurality of inserts 12 used, each of which has a base 13 and a body 14 that has a forms elastically yielding retaining member. The body protrudes from the seal on the circumference of the disc after it has been formed the side of the same which is intended to be arranged on the projecting frame 15 (Fig. 2), which latter is provided in the body and includes the receiving opening for the window. The liability of the base 13 of the Inserts on the rubber of the seal 11 is also made according to the method described in the aforementioned disclosure achieved.

The inserts 12 are preferably made of polymer material and advantageously of the one under the trade name "NYLON" known material, loaded with glass fibers, carbon fibers or aramid fibers, which make the elastic

improve the modulus of the base material and the latter give the necessary elasticity and rigidity. The body 14 of each insert is preferably (however not necessarily) fork-shaped and has two parallel prongs, each with a tooth 16 ends with a first outside undercut 17 and a second inside undercut 18 is provided. The first outside undercut 17 is intended to snap into place on To attack the edge of a corresponding seat 19 on the frame 15 in the area of each on the disc located holding member is provided.

Since the body of each holding member has a rectangular plan shape, the plan shape of the seats is also 19 rectangular, which, as can be seen in the drawing, preferably have a drawing depth to a greater one To allow elongation of the fork-shaped body 14, so that a greater elasticity is achieved in a corresponding manner the same results.

The seats 19 are preferably arranged on the frame 15 as shown in Fig. 2, from which it can be seen that the seats lying on the opposite sides of the circumference are arranged perpendicular to one another. This arrangement enables the inclusion of any, in itself already narrow (JL0.25 mm) tolerances, with all geometric sizes are given by the shape.

The second, on the inside of the prongs of the body 14

provided undercut 18 is used for snapping Receiving and holding a safety element against slipping out, which after insertion between the Prongs, after the arrangement of the disc, a compression and consequently an unintentional slipping out of the holding member 14 prevented.

As can be clearly seen from Fig. 1, there is Security element from the lance-shaped end of a continuous rib 20 on the inside a rigid cover strip 21 or a portion of any rigid cover inside the vehicle compartment is provided. The rib 20 thus fulfills the double function of a security element in the aforementioned sense and that of a retaining element which is snap-mounted for the rigid cover strip 2T.

FIG. 3 illustrates the sequence of operations in assembling the pane, the first of which Operation (indicated by A) in the arrangement of the disc 10 in relation to the frame 15 in such a way that the holding members 14 and the seats 19 are aligned with one another. In the second step B, the disc is from pressed on the outside in order to move the holding members 14 into the seats 19 so that they snap into place on the edges of the seats. In this phase the in Sealing lips 29 provided in a known manner on the seal 11, as shown in the drawing figure, compressed and pressed against the body panel. The last assembly phase, labeled C, exists

finally, that the cover strip 21 is inserted with a snap, so that the holding members 14 are blocked will. Due to the perfect reversibility of the assembly, the work steps for dismantling the pane run in reverse order.

The variant according to FIG. 4 relates to a solution in which the safety element against slipping out is provided individually for each holding member and from one Stopper 30 with a lance-shaped handle 31 is made with the on the inside of the prongs provided undercut 18 comes into engagement. Preferably, the plug 30 is integral with the body 14 of the holding member, with which it remains connected by means of a film 32.

The variant according to FIG. 5 shows an insert 120 with * a base 121 which is embedded in the rubber of the seal 11 and glued to this, and an elastic one fork-shaped body 140, which is separated from the base and with this for example by means of a Threaded extension 141 is detachably connected, which engages in a corresponding threaded seat of the base 121. These Solution enables the body 140 to be replaced in the event of breakage or damage to it, which is particularly important is important in the phase of reassembling the disc, for example when dismantling the same one or more of the holding organs should have broken due to a mistake.

The variant shown in Fig. 6 illustrates a pin-like designed auxiliary holding member 150, the Use in combination with the described snap-on retaining elements 14-140 for special Assembly conditions, i.e. when the seat of the holding member is in a blind space 151, e.g. inside a hollow rib N der Body flows, can be useful. In this case, the pin or pins 150 are first in the relevant Seat 190 with the displacement of the disc 10 parallel to itself and taking advantage of the elasticity of the Seal 11 to keep the disc slightly spread apart with respect to the end position, inserted. Then will the disc rotated and pressed to engage the snaps 14-140 with the respective retaining seats bring to. Of course, pegs, like pegs 150, can be arranged in the area of only one side of the disk to allow the aforementioned rotation and translation.

While maintaining the basic idea of the invention, the details of the training and the Embodiments in relation to the above exemplary embodiments in a wide range can of course be varied without thereby going beyond the scope of the invention.
