Description

• t · «

The invention relates to a blocking part in flat square form for stabilizing glass panes and in particular insulating glass panes in wings of windows, doors or the like made of wood, plastic or light metal with a support surface on the pane side and a support surface on the rebate side provided with at least one recess.

Blocking strips of this type are well known and are used in practice in different sizes and thicknesses. In many cases, they are used in accordance with the guidelines provided by the respective sash or profile system manufacturers, which include, for example, information on the respective height and length of the blocking as well as the positioning of the blocking.

Blocking parts in the form of solid blocks, grid blocks and also block bridges are known, although the first two blocking parts mentioned have the general disadvantage that they do not allow for effective rebate drainage and ventilation, particularly in the case of so-called glass rebate cavity glazing. As a result, glass damage can occur, particularly in the insulating glass.

With the so-called block bridges, which have at least one channel on the fold side running parallel to the length of the block part, the problem of blocking the water drainage in the fold is eliminated, but with these known block bridges there is on the one hand the risk that if the blocks are placed on top of each other they will tip over, which can lead to glass damage, and on the other hand these known block bridges are difficult to slide over each other, since

the recess provided on the fold side/ i.e. lower recess does not allow simple parallel movement of the parts, but leads to interlocking.

The object of the invention is to design a blocking part of the type mentioned at the beginning in such a way that it can simultaneously fulfill the punctures of the solid blocks, grid blocks and block bridges used to date, ensures good water drainage, has no tendency to tip over when stacked and allows problem-free sliding over one another for the purpose of stacking, in particular while simultaneously fixing one another.

This object is achieved according to the invention in that at least one channel extending over the entire length of the flat cuboid, running at least over partial areas of its length at an angle to the longitudinal center plane of the flat cuboid and open at both ends of the flat cuboid divides the support surface on the fold side into mutually spaced-apart partial support surfaces.

The channel design provided according to the invention ensures, on the one hand, that water can drain freely, i.e. that water that penetrates the glazed sash can pass unhindered through the block to the water drains provided in the sash and flow away, and on the other hand, the nesting of the partial support surfaces eliminates any possibility of tipping over when blocks are placed on top of one another and enables blocking parts to be pushed over one another without any problems.

Blocking parts designed according to the invention can be used universally for all purposes encountered in practice, which results in significant advantages in storage, since the storage of different types of blocks is no longer necessary and only the universal block designed according to the invention needs to be manufactured in different sizes and kept in stock in stores.

Another significant advantage resulting from the invention is that the nested support surfaces ensure a high level of stability for each blocking part, while optimizing the overall weight, which in turn enables cost-effective production without compromising on quality.

There are a number of options for the design of the channel path, but what is essential in all embodiments is that the partial support surfaces formed by the channel path receive a multi-point support distributed over their length for each support line running parallel to the longitudinal extension of the flat cuboid, since tipping processes can be completely eliminated in this way.

Preferably, both the support surface on the pane side and the partial support surfaces on the rebate side are provided with transverse and/or diagonal grooves in order to make slipping more difficult or prevent it, both when using individual blocks and when using blocks arranged one above the other.

Blocking parts according to the invention can be manufactured in particular using the injection molding process from different materials, in particular from PS, PP, NPE and PVC, however, in all embodiments the basic design principle expressed in claims 1 and 2 is used.

Particularly advantageous embodiments of the subject matter of the invention are specified in the subclaims.

The invention is explained below by way of example with reference to the drawing, in which:

Fig. 1 a top view of the fold-side support surface arrangement in connection with a diagonal channel,

Fig. 2 a plan view of the support surfaces on the fold side when using an angled channel,

Fig. 3 is a plan view of the support surfaces on the fold side when using a meander-shaped channel, and

Fig. 4 is a plan view of the fold-side support surfaces when using a double arrangement of meander channels.

Fig. 1 shows a blocking part made of a plastic injection-molded part in the form of a flat cuboid 1. The length of such flat cuboids is, for example, 100 mm, while the width is in the range between 20 and 30 mm and the thickness is graded between 1 and 6 mm. However, these details are not to be understood as limiting.

-s-

The flat cuboid 1 has long sides 2, 3 and end faces 4, 5, with a continuous channel 6, preferably U-shaped in cross section, extending between these end faces 4, 5. This channel 6 enables unhindered flow of water that has penetrated into the wing to the corresponding water drains.

Partial support surfaces 7, 8 are formed through the channel 6, which are preferably provided with recesses 9 so that the partial support surfaces have a rib structure.

The channel 6 runs essentially diagonally and merges into axially parallel opening sections in its front end areas. It is important that the course of this channel is selected in such a way that the partial support surfaces 7, 8 formed form a multi-point support distributed over the length of each support line running parallel to the longitudinal extension of the flat cuboid 1, which eliminates the possibility of these flat cuboids interlocking and thus tipping over when such flat cuboids are arranged one above the other. By eliminating any possibility of tipping over, it is ensured that glass damage resulting from this undesirable effect can no longer occur.

In the following figures, corresponding parts are marked with the same reference numerals as in Fig. 1.

The variant according to Fig. 2 differs from the embodiment according to Fig. 1 essentially in that instead of a diagonally running channel 6, an obtuse-angled, V-shaped channel 6 is used, which, however, is in the same way as the

Diagonal channel according to Fig. 1 ensures that the partial support surfaces 7, 8, which in this case are again designed in the form of webs by means of recesses 9, form a multi-point support distributed over the length of each support line running parallel to the longitudinal extension of the flat cuboid 1.

Fig. 3 shows a variant in which the continuous channel 6 has a meandering shape. The partial support surfaces 7, 8 are formed by edge regions running parallel to the longitudinal extension of the flat cuboid 1 and by projections which extend inwards from these edge regions and interlock with one another. These projections can run at right angles and/or at an acute angle with respect to the longitudinal center plane.

The variant according to Fig. 4 shows a blocking part with two mirror- and center-symmetrical, meander-shaped channels 6, 6', which were created by using a central web 10, which has projections on both sides, each of which is located between corresponding, but longitudinally offset, projections on lateral webs. In this embodiment, which is characterized by particular stability, a particularly pronounced, uniform multi-point support is obtained along the conceivable support lines parallel to the longitudinal extension of the flat cuboid 1.
