The surface of the block on the glass side can be covered completely with a uniformly thick layer of rubber elastic material. The block has at least one cam of soft rubber material on its surface. The block surface (11) can be covered completely with a layer of soft rubber material having at least one protruding cam which is integral with the remaining material.

Description

The invention relates to a block for support of glass panes in door or window frames, with one block body made of rigid plastic that directly or by means of relatively immovable blocks on one Frame area is supported, and the glass-side soft rubber Has material.

Such a block is known from DE-GM 8 403 648. The block body is plate-like and has continuous Holes or slots with which the block and the stopper be assembled. The assembly takes place in such a way that first the stopper with its self-adhesive Surface fixed on the glass side and then the block with one of the holes is pushed over the stopper. Consequently the block can easily fall down again. When the glass pane rests on the frame, the stopper becomes completely pushed into the hole of the block and can do nothing to compensate for the edge offset, thus to make the pressure distribution of the Glass pane due to glass edges of different heights. Such one Edge offset can be up to 2 mm.

From DE-GM 8 912 744, which shows the prior art according to the preamble of claim 1, is a block with one of its own stiffness Plastic existing block body known, the is supported directly on a frame surface and on the glass side arranged compliant material. The compliant Material is part of a disc support part, which from Block part is separate and a support layer of reduced friction coefficient has, so that with the compliant Material-providing disc support part relative movements to Block body can run. This complex construction of the Block is due to the fact that the block for supporting Panels with multilayer laminated glass is intended. Layered Laminated glass is particularly heavy and as a result of Manufacturing tolerances may vary depending on the length of the individual Layers of a glass pane in the millimeter range. For common insulating glass panes and less weight glass panes such a complex construction is not necessary.

The invention is therefore based on the object To improve blocks with the characteristics mentioned at the beginning, that he reduced the specific burden by simple means allowed to reach the glass panes, for example a lower specific load on the edge a single sheet of glass due to uneven cut one Glass edge along its length or due to edge offset an insulating glass pane combined with a reliable one relative adhesion between the block and the glass sheet against slipping.

This object is achieved in that the block body at least on one for immediate disc support predetermined partial area of a glass-side block body surface is firmly connected to the rubber-soft material.

Accordingly, the block body forms with the rubber soft Material an integral component. The log is one Handling unit which does not have to be provided for that two separate parts are properly assembled be, especially while ensuring their relative Movability. The rubber-soft material can withstand the stress be configured accordingly through the glass pane and in particular it is also possible to use it only in sections to be provided on the block body surface on the glass side. The is particularly advantageous if the block through the rubber-soft material essentially only against relative Moving to the glass pane should be secured. The firm connection of the rubber-soft material with the block body can be achieved with simple means since it is on a heavy-duty connection strength against relative Moving does not arrive. The log is either directly on supported a frame surface, namely when its thickness at the same time the distance to be compensated between the glass side and corresponds to the frame side. If this distance is greater, then the block can also be made using relatively immovable blocks can be used together with the rubber switches The block comprising the material forms the total thickness or the desired distance between the glass side and frame side together bridge.

A particularly simple, easy to manufacture and to mounting embodiment of the block is given when the Glass-side block body surface with a uniform surface thick layer, rubber-soft material is provided. Such a block offers the glass pane a comparative large contact area so that the layer is rubber-soft Material can be kept thin. It offers optimal security against slipping.

The block can also be designed so that it at least one cam attached to the block body surface made of rubber-soft material. Such an arrangement is sufficient for lower loads on the block, albeit the security requirements against Are not too high. Comparatively prominent Cams also allow the block to be used with correspondingly large tolerances between the glass pane and Frame area.

An optimal design of the block is made possible if the glass-side block body surface with a full surface Layer of rubber-soft material is provided, the least a projecting one piece with the rest of the material Has cams. The projection of the cam ensures that Bridging according to large tolerances between the Glass pane and the frame surface and the full area of the rubber-soft layer ensures optimal distribution of the Forces at point loads on the glass panes or their Edge.

It can be advantageous to design the block so that the glass-side block body surface at least one out of it Plate level resiliently projecting curvature made of plastic has, which protrudes over the rubber-soft material that on the areas next to the curvature Layer on the glass block surface covering the entire surface forms. This block also allows its use on large ones Tolerances between the glass pane and the frame surface and ensures an optimal distribution of forces at the point load points of the glass panes. The one from the plate level the bulge protruding from the block body surface, made of plastic allows easier handling of the block, e.g. when moving the block in contact with the glass pane, to position the block. The comparatively low friction of the plastic curvature on the The edge of the pane makes it easier to move it without the soft rubber Material already on the glass pane at this point is present. It is also possible as a compliant material to use plate-like material that comparatively is easy and inexpensive to manufacture.

The block can advantageously be designed in this way that the cams and the curvature rubber-soften the layer Material protrusions are that between Longitudinal panel edges with an arcuate outer surface extend from one to the opposite longitudinal edge. As a result, the cams and bulges take all of them Panel width between the panel longitudinal edges, so that the remaining areas of the glass-side block body surface with flat layers of rubber-soft material can be covered.

Another advantageous embodiment of the block is achieved in that it is near its two ends each has a cam or a curvature, if necessary extending between the longitudinal edges, evenly over the width of the cams or arches have distributed ribs. This makes the block parallelism when creating guaranteed to the glass pane and at the same time the risk of Slipping reduced on the glass edge, in particular also when the contact area is small and in the case of made of plastic, the coefficient of friction is only minor.

The block can advantageously be designed in such a way that that it has at least one vertical edge on the longitudinal edge to the glass side Block body surface has projecting side flap, the with a glass adhesive to be applied on the glass side is to be provided. The block can then pass through the glass pane Glued to be fixed so that the relative position is secured and the assembly of the glass pane with the frame is simplified can be.

It is advantageous if the rubber-soft material with the block body by injection or by locking connected is. Both connection methods guarantee a sufficiently firm connection, the spraying particularly in the case of large areas Connection is used, so with plate-like rubber soft Material, and the locking with small-area rubber-soft Material, if only for example is designed as a single cam.

The invention also relates to a method known from DE-GM 8 912 744 to assemble a door or window frame with a Glass pane over at least one block with its on a frame area directly or by means of relatively immovable Blocks lying on block body is supported, the glass-side block body surface over compliant material the edge of the glass pane is brought into contact.

From DE-GM 8 912 744 it is known the block body to place directly on the frame surface and that the compliant Stick the layered support part to the glass edge, for which the necessary to seal the interior of the pane Sealant is used. That doesn't just result Difficulty positioning the compliant material having part on the glass pane relative to the block surface placed block body, but also needs an assembly that allows the sliding of the compliant Block material on the block body, for example, through appropriate purity care. Furthermore, this known method assumes that Adhesive should always be contacted with sufficient sealant can, otherwise a special adhesive would have to be used.

In contrast, the invention is based on the object the above method to improve the assembly of the frame and the glass pane, especially without regard to the formation of an insulating glass pane with regard to sealant present in the adhesive area.

This object is achieved in that a rubber soft as a flexible material block that is attached to a Long edge at least one vertical to the glass block surface has projecting side flap on the glass-side tab surface with a glass adhesive is provided that the block then before inserting the glass sheet glued into the frame on the side of the glass pane and that afterwards the glass pane provided with the block with the block body resting directly on the frame surface is pushed into the frame.

This method ensures that the glass pane completely regardless of the presence of a block or several blocks can be assembled with the frame. The block only needs to be in a predetermined position to be glued to the side of the glass pane, i.e. with one Glue that very quickly has the required adhesive strength developed. Then the glass pane can e.g. with the help of Suction cups can be lifted and moved, also by the block body slipping on the frame surface, e.g. with wooden windows with laterally smooth groove bottom. A sliding of the glass pane on a placed in the frame before installation Because of the rubber-soft material, block would run the risk of that the block would slip and above all that the glass pane not as close as possible to the outside of the window limited frame rollover would be pushed.

The block shown in Fig.1 is a lattice block, like results from Fig.1c. So it consists of a closed one Plate 22, which is supported by a plurality of webs 23 which is in the longitudinal direction and in the transverse direction, respectively extend at right angles to each other due to the design. The log is essentially elongated and its Width is determined e.g. through a frame groove in which it is housed becomes. The block body 10 has a glass side Block body surface 11 extending from an outer surface of plate 22 is formed. On this glass-side block body surface 11 there is a layer 14 of rubber-soft material, the covers the entire area 11. During the block body 10 made of polypropylene, for example, is the rubber soft one Layer 14 is a thermoplastic elastomer overlay.

The layer 14 is provided with cams 15 on the glass side project. These cams 15 are in one piece with the layer 14 connected and can be produced together with this, e.g. by spraying. The cams 15 are near the ends 19 of the block body 10 arranged and ensure one considerable lead, so that accordingly tolerances between the glass pane and the frame or the block body surface 11 can be bridged. The bridging causes that the block lies non-slip on the glass pane, so for example, even if it passes through the glass pane or whose weight is not loaded, but between her and the frame surface is installed on a vertical spar.

A peculiarity of the block of Fig.1 to le exists in that 17 side tabs 21 are arranged on one of the longitudinal edges are. These side tabs 21 protrude on the glass side and its tab surface 24 can be covered with a glass adhesive or a Glue to be coated, which is a fast bearing Connects to glass. It is then possible to use block 10 attach to the edge of a sheet of glass by using the side tabs 21 pressed against the outside of the glass. That happens before the glass pane is inserted into the frame. The adhesive develops a holding force that makes it possible Insert glass pane in the frame without being on the Liability. The block can be placed directly the block body 10 on the frame surface or in plant pushed into the frame on the side of the frame surface become. Since the block was glued in the same way as the Block positioned relative to the glass pane when installed there should be no danger of the Block on the edge of the glass pane because this is from the rubber soft Layer 14 is prevented. On the other hand, it is not necessary, the glass on the rubber-soft layer postpone what because of the comparatively large liability between this rubber-soft layer and the glass pane would not be possible or only possible under difficult circumstances.

Fig.2 shows a variant of a block, the glass-side Block body surface 11 with two near ends 19 arranged bulges 16 is provided, for example correspond to the positions of the cams 15 according to FIG. 1. This However, curvatures 16 are part of the block body 10, wherein they spring out of the plate level and with it are connected in a way that facilitates their deformation. The Detail of Fig.2a shows that the curvature, for example has a depression 25 on its underside. This Recess 25 is a weakening of the material thickness of the curvature 16, so that this is loaded by the glass especially here will deform and an impression of this Curvature 16 allowed by the weight of the glass sheet. The Training of this curvature can be practical Requirements are made accordingly. Thereby should also express that the curvature 16 in the rest can be arbitrary, that is also different from the representation in Fig.2a.

In Fig.2 the glass-side block body surface 11 is adjacent the curvatures 16 with a uniformly thick layer 12 rubber-soft material provided, applied in three parts is, namely the end of the bulges 16 and between this. In the event of a load on the bulges 16 through a sheet of glass, the bulges are compressed and the glass pane comes to rest on layer 12, so that there is a correspondingly large liability, whereby protruding support points in the sense of that known with wood Beechwood effect can be relieved. The one on the vault 16 provided grooves 20 which are between the longitudinal edges 17th of the block, also work, while at the same time also to reduce the displaceability of the block contribute to the glass pane.

3a shows a block, the glass-side block body surface 11 only near the block ends 19 with each a cam 13 made of rubber-soft material is provided. This Cams are used in particular to bridge tolerances between the glass pane and the frame, but are also sufficient to then to prevent the block from accidentally coming out of the can move the intended position, e.g. on a vertical Frame spar. The amount of rubber-soft material is in particularly low in this case. The connection of the cam 13 with the block body surface 11 can be done as in Case of the embodiments of Fig. 1,2, namely by injection or stick on. But it is especially in this Case also possible to make a snap connection by the block body in its manufacture by spraying with a Mounting hole is provided in the one when manufacturing of the cam 13 provided by injection locking projection is snapped into place.

In all cases of Figures 1 to 3 it can be seen that the cams 13, 15 or bulges between the longitudinal edges of the plate 17 extend over the entire width of the block, with an arcuate outer surface 18, the provides optimal adhesion with the least amount of material, as well as an attractive appearance.

In Fig.4a, 4b it is shown that the glass-side Block body surface 11 of a block also with a uniform strong layer 12 rubber-soft material can be provided can be used without protruding cams or bulges come. The block is in the case of Fig.4a as Bridge formed, so in a conventional manner with a Water passage 26 between side webs 27. Fig.4b shows in Compare this to a glass rebate insert, which is the space of a Fills the frame groove of a profile frame and in turn can support a block. Also a block according to Fig.1 to 3 can be used as a glazing seam insert, the Cam 13, 15 and the arches 16 between them a support block can hold, then not in the longitudinal direction of the block can slip, e.g. on a vertical frame spar. Of the rubber-soft material of layers 12, 14 and also rubber-soft Material of the cams 13, 15 prevents slipping of such an additional support block, which is then required can be if there are larger distances between glass pane and frame area must be balanced.
