Description

The invention relates generally to a stabilizing device for a plurality of glass panes arranged in a row and parallel to one another, in particular motor vehicle glass panes, with a plurality of spacer tabs assigned to the individual glass panes, which spacer tabs can be placed on the edge of the glass panes, an upper part and a device for receiving of a tensioning strap in the upper part, which spacers also serve as stabilizing! tion device are combined by form-locking elements to form a stabilization bar, in which the front and the back of the spacers abut with coupled form-locking elements. - The individual spacers are generally placed or clipped onto the upper edge of the assigned glass pane from above. This direction determines the direction of touchdown. The clamping legs are set up accordingly. They lie opposite each other on the individual distance riders or are offset from one another. Often the arrangement is such that, in association, two glass panes are assigned to a spacer. However, the arrangement can preferably also be made such that a spacer is to be placed on each disc.

In the stabilization device of the generic type (known from practice), the positive-locking elements on the front are designed as father elements, on the back as mother elements. It doesn't matter which side is referred to as the front side and which side is referred to as the rear side, once you have made a corresponding definition on the spacer tabs, So in the association of the spacers to the stabilization device, the front and the back of the individual spacers are not interchangeable. In other words, it is not possible to rotate a distance rider in relation to one of its neighbors by 180 ° around an axis parallel to the direction of contact and orthogonal to the direction of friction without disturbing or canceling the positive connection. This is disadvantageous because, for the purpose of placing the individual spacers, careful manipulation must be carried out, which ensures that the positive locking is maintained and is not disturbed by interchanging the front and rear. In other words, as part of the known measures, all spacers must point in one direction with their front and vice versa with their back. If this does not happen and the interlocking is disturbed, the stabilizing strips and thus the stabilizing effect are, as it were, interrupted at this point, which is extremely disadvantageous in the manipulation of the installed glass panes, particularly in the context of automatic production.

In contrast, the invention has for its object to further develop a generic stabilizing device so that the front and rear sides are interchangeable in the association of the spacer tabs to the stabilizing device, but nevertheless the perfect form fit is ensured.

To achieve this object, the invention teaches that the positive locking elements are designed so as to be invariant in rotation, both on the front side and on the rear side of the spacers, that the individual spacers can be converted by 180 ° in the association of the stabilizing bar around an axis parallel to the mounting direction and orthogonal to the direction of friction . Rotation invariant refers to the fact that the positive engagement is not impaired during the described rotation. This can be done in different ways with regard to the geometric design and the arrangement of the form-locking elements.

An embodiment is characterized in the basic concept that the positive locking elements are designed with respect to a free zone running in the direction of attachment of the spacers on the one hand as father elements, on the other hand as mother elements, both on the front and on the back, and that the father elements on the The front of each spacer nut elements on its back, opposite the nut elements on the front of each spacer father elements on its back. In the context of this embodiment, the parent elements and the mother elements can basically be of any design, provided the above teaching on technical action is observed, as long as they are only complementary as form-locking elements. In any case, it is ensured that the interlocking of the individual spacers in the stabilization bar is not disturbed if a spacer in the row of spacers is rotated by 180 ° about an axis parallel to the mounting direction, in other words, the front and rear are exchanged. As a result, the spacers can be used without any special sorting be placed on the assigned glass panes. It is within the scope of the invention to arrange the interlocking elements on the upper part of the spacers or on their legs or to combine both measures. - A preferred embodiment, which is characterized by simplicity and reliability, is characterized in that the form-locking elements have ribs of length V as father elements and grooves of length MI as mother elements, which run transversely to the direction of insertion of the spacers, that the ribs project against a reference surface and that the grooves spring back against this reference surface and the individual spacers in the stabilization bar are displaceable relative to one another in accordance with the difference MV. This makes it easier to bring the individual spacers, which are connected to the stabilization bar, into positive engagement when these spacers are placed on the edge of the assigned glass panes, be it manually or automatically. In the stabilizing device described, the devices for receiving a tensioning strap in the upper part of the touch-down tabs are expediently designed as reversed T-shaped recesses, the T-web of which is designed to be open to the edge of the spacer tabs for inserting a tensioning strap. An additional stabilizing bar could also be insertable in such a recess.

Another embodiment of the invention is characterized in the basic concept in that the positive locking elements consist of point elements protruding from the front surface and from the rear surface as parent elements and between the point elements serving as mother elements, in which the point elements can be inserted, so that the point elements can be inserted rooms are arranged according to a predetermined grid with equidistantly in alternating order on the front and on the back of the individual spacers in alternating order on the one hand in rows and on the other hand in rows crossing rows, the form-locking elements in the crossing points of the rows and rows as well as the rows Rows belong to the fact that the point elements and the point element gaps on the front of the individual distance tabs are opposite point elements and point element gaps on the back of the individual distance tabs, and that the individual distance tabs in the union to the stabilization bar with respect to the adjacent spacer tabs by half a division, three times that half the division, five times half the division, etc. with odd multiples of half the division, are offset from one another. The point elements can have a circular plan with respect to the front surface or the rear surface. However, the point elements can also be provided with a square or rectangular plan with respect to the front surface or the rear surface. In addition, other layout shapes, for example polygonal, such as uniformly hexagonal, are also possible. The size of the point elements with regard to diameter or edge length and height is also arbitrary within the scope of the invention and depends on the respective operational circumstances. A preferred embodiment of the invention is characterized in this context in that the point elements have a diameter or an edge length of 2 to 5 mm and a height corresponding approximately to their diameter or their edge length. It is within the scope of the invention, the point elements and the To arrange point element gaps on the upper part of the spacers or on their legs or to combine both measures. It is understood that the point elements z. B. pyramid-shaped and / or conical and / or cylindrical. The device for receiving the tensioning strap can be set up in various ways within the scope of the invention. An embodiment, which is characterized by simplicity and reliability, is characterized in that the device for receiving a strap consists of an inverted T-shaped recess, the T-web is open to insert the strap towards the top of the spacers. An additional stabilizing bar can be inserted into the device for receiving a tensioning strap. It could also be used as a hold-down from above. - In the last-described embodiment of the stabilization device, the spacers carry point elements and point element gaps on the front as well as point elements and point element gaps on the back, in other words, in alternating order, with the same grid on the front and back with a given pitch dimension, parent elements (point elements) and mother elements ( Dot element gaps). Adjacent spacer tabs can nonetheless be united by positive locking, in that they are offset by half a division, three times half the division, five times half division, etc. with odd multiples of half the division. The displacement does not interfere and is determined by the absolute size of the point elements and thus the point element gaps. The offset can therefore be made very small by making the pitch small. Add to that the distance Riders on the glass panes when putting them on or afterwards when they are combined to form the stabilization bar in accordance with the displacement to be taken, can be moved without difficulty simply by pressing the spacer tabs together.

In general, you will inject the plastic spacers. They can have weight-saving recesses.

The spacers 1 have clamping legs 4 which can be placed on the edge 2 of the glass panes 3, an upper part 5 and a device 6 for receiving a tension band 7 indicated by dash-dotted lines in the upper part 5.

The spacers 1 of FIGS. 1 to 9 function as a stabilization device because they are combined to form a stabilization bar by complementary form-locking elements designed as father elements 8 and nut elements 9, in which the front 10 and the rear 11 of the spacers 1 with coupled form-locking elements 8, 9 abut each other. This is shown in particular in FIGS. 8 and 9. From a comparative view of FIGS. 1 and 2, it can first be seen that the positive-locking elements with respect to a positive-free free zone 12 running in the direction of attachment of the spacers 1 are designed on the one hand as father elements 8 and on the other hand as mother elements 9 are. This applies to both the front 10 and the rear 11, for which reference is made to FIG. 3. For the purpose of identification, the area of the front 10, which is equipped with father elements 8, has also been provided with an arrow and the letter V in the figures. Accordingly, the area which carries the nut elements 9 has been provided with a note and the letter M. The same applies to the rear side 11. These arrows have also been entered in FIG. 5. - The free zone 12 can be of any width and also very narrow. In Fig. 1 mag they have a width of about 5 mm. In contrast, in FIG. 6 it is reduced to an extremely narrow area. The arrangement, as can be seen in particular in FIG. 5, is such that the mother elements 8 on the front 10 of a spacer 1 mother elements 9 on its back 11, the mother elements 9 on the front 10 of each spacer 1 father elements 8 on its back . In the exemplary embodiment in FIGS. 1 to 9, the interlocking elements have ribs 8 as father elements and grooves 9 as mother elements, _I which extend transversely, namely orthogonally, to the plug-on direction of the spacers 1. The ribs 8 project against a reference surface 13, which corresponds to the surface of the free zone 12 in the exemplary embodiment and according to the preferred embodiment of the invention. The grooves 9 jump back relative to this reference surface 13, so they are, as it were, embedded in it. It is thereby achieved that the individual spacers 1 in the stabilization bar can be displaced in relation to the free zone 12 in accordance with the width S measured transversely to the mounting direction. In the exemplary embodiment, the device for receiving a tensioning band 7 consists of a T-shaped recess 6, the T-web 14 of which is open towards the upper edge of the spacer 1 for inserting the tensioning band 7. In addition, a stabilizing rod 15 can also be inserted into this T-shaped recess 6. It could also be used as a hold-down from above. The spacer 1 shown and thus the stabilizing device as a whole consist of plastic and have been produced by means of the injection molding process. It was not shown that they can have weight-saving or material-saving cavities. It is understood that the spacer 1 of the stabilizer according to the invention tion device can not only plug on the upper edge 2 of an associated glass sheet 3. The embodiment according to FIGS. 1 to 5 is set up so that a spacer 1 is assigned to two glass panes 3 in association with the stabilization bar. 7 to 9, in contrast, a spacer 1 is also assigned to each glass pane 3.

In the embodiment according to FIGS. 10 to 16, individual spacers 1 have been represented by another embodiment of a stabilization device according to the invention, and also in the assembled state, which thus serve as part of the stabilization bar belonging to the stabilization device. The stabilizing device serves to stabilize a plurality of glass panes 3, which are arranged in a row and parallel to one another, in particular motor vehicle glass panes for the purpose of handling. A plurality of spacers 1 assigned to the individual glass panes 3 are used. In the embodiment according to FIGS. 10 to 14, each glass pane 3 is assigned an individual spacer 1. In the embodiment according to FIG. 16, a single spacer 1 works for two glass panes 3, as indicated by the figures mentioned. The spacers 1 have clamping legs 4 which can be placed on the edge 2 of the glass panes 3, an upper part 5 and a device 6 for accommodating a tensioning band 7 indicated by dash-dotted lines in FIG. 10 in the upper part 5. The spacers 1 are furthermore a stabilizing device by means of form-locking elements 8, 9 united a stabilizing bar, FIGS. 13 to 15 show a section made up of two spacers 1 from such a stabilizing bar. It can be seen that in the stabilization bar The front and the back of the spacers 1 with coupled form-locking elements 8, 9 abut each other. From the _Fi g. 11 and from a comparative consideration of FIGS. 12 to 15, it can be seen that the form-locking elements consist of point elements 8 protruding from the front surface and from the rear surface and father elements and point element interspaces 9 arranged between the point elements 8 as mother elements, in which the point elements 8 can be used . The expression "point element space" includes several embodiments of the spatial design. If one mentally starts from a flat surface and the point elements 8 are raised opposite it, the point element interspaces 9 arise without further shaping. This has been shown in the drawing for reasons of clarity. The point element interspaces could also be depressions in a flat reference surface over which the point elements protrude. The point elements 8 and the point element interspaces 9 are arranged according to a predetermined grid with equidistantly in alternating sequence on the one hand in rows and on the other hand in rows crossing the rows 10 on the front 10 and on the back 11 of the individual spacers 1 with the same pitch. It can be seen in FIG. 11 that the interlocking elements 8, 9 belong to both the rows and the rows at the crossing points of the rows and rows. As the shape of the front side 10 shown in FIG. 11 looks, the rear side 11 also looks identical. The arrangement is thus such that the point elements 8 and the point element spaces 9 on the front 10 of the individual spacers 1 point elements 8 and point element spaces 9 on the rear 11 of the individual spacers 1 opposite and that the individual spacers 1 in the union to the stabilization bar with respect to the adjacent spacers 1 are offset by half a pitch T against each other. You can see that from the figures. At the same time, one realizes that the offset could also be three times half the pitch T, five times half the pitch T, etc., with odd multiples of half the pitch T. In practice, an offset of half a pitch T generally occurs automatically. In the exemplary embodiment according to FIGS. 10 to 16, the point elements 8 have a square outline with respect to the front surface or the rear surface. In Fig. 11 it was indicated by dash-dotted lines that this floor plan can also be circular. It could also be rectangular. For the rest, the geometry of the interrelationships in the exemplary embodiment is shown more roughly than is necessary in practice. In practice, the point elements 8 z. B. a diameter or an edge length of 2 mm and a height corresponding to their diameter or their edge length. The point elements 8 are otherwise conical, pyramid-shaped, cylindrical, wart-shaped or similar. 10 to 16 you can see the device 6 for receiving a tension band 7. It consists of an inverted T-shaped recess 6, the T-web 14 for inserting the tension band 7 to the upper edge 16 of the spacer 1 is open towards the edge. An additional stabilizing rod 15 could be insertable into the device 6 for receiving a tensioning band 7, which was indicated by dash-dotted lines in FIG. 10.

The individual spacers 1 are expediently injection molded from plastic. They can have weight-saving recesses, which has not been shown.
