Description

The invention relates to a guide angle for a flexible band for transmitting "force around the corner", in particular push or pull movements in Eckumlenkungen for transmission of windows or doors. Also an assembly process is claimed.

Guide angles or corner deflections are known in various embodiments, cf. DE-U 7418 567 (GU ) and DE-A 20 10 407 (Siegenia ). Such a guide angle generally has three supporting and guiding areas or "sections", two of which extend over the two legs of the angle and over which connects the two legs corner region or are formed thereof.

The said DE '567 , which discloses the features of the preamble of claim 1, has in the two legs integrally formed, angularly shaped guide pieces (referred to therein with 10, 11). They form in the longitudinal direction spaced a guide channel, in which a steel strip can be inserted and guided. In the corner is defined by an arcuate support strip which is inserted between the innermost holding pieces of both legs, a guideway which supports the steel strip as there called "deflector" and leads. Another support strip, there 9, is located on the other side of the deflecting member, and between the two support strips, the deflecting member is guided in the corner region along an arcuate guide section. In the aforementioned DE '407 a one-piece guideway is provided in the corner region, which is wave-shaped there to reduce the friction. On the legs are lateral webs (there 4.5) with edge breakthroughs, there 18, provided which lead the steel strip provided there in the web area. In the corner is the local FIGS. 1 . 4 and 5 a substantially open edge guide is provided, which has a channel (as slot arc), which is about twice as high as the steel strip is strong. The edge sides are closed in some places, to which serve the webs 17 shown there. In the area of the corner of the open-edged slit arc is piecewise closed by said webs, wherein the webs are arranged over a range once on one side and once on the other side, see. there page 3, middle paragraph, at the end.

Out CH-B 317 810 (Weidtmann ) is known a guide angle with guide pieces.

It is an object of the invention to develop a guide angle so that it allows safe operation in the corner area with little effort and, moreover, with a few parts allows easy mounting of a corner guide provided with such a guide angle. The guide in the corner area should be low-friction.

This object is solved by claim 1 or 17.

With this design, a uniform and secure guidance of the band is possible over the entire guide length of all three support and guide areas, in particular also in the corner area, without the band transmitting the force being exposed to greater loads due to excessive friction during its movements.

At least in the corner region an arcuate support and guide surface is provided along which the upstanding guide pieces of the opposite rows are arranged against each other in gap or offset. This makes it possible to form the guide angle with all its details as a one-piece casting according to claim 7. By arranged on gap guide pieces easy removal of the casting is achieved in its manufacture.

It has proven to be advantageous if the upstanding guide pieces of the two opposing rows are arranged continuously offset to gap or against each other on all support and guide areas of the guide angle (claim 4).

Further advantageous embodiments will become apparent from the other dependent claims.

A corner drive may be equipped with a guide bracket according to the claimed invention.

There are also advantages only less mounting hardware and assembly steps, in the assembly or assembly process (claim 17).

Figure 5a, Figure 5b, Figure 5c

show cross sections through a leg of the angle FIG. 5 according to the in FIG. 5 indicated cutting planes 6, and 7.

The guide angle is shown in the figures in the preferred embodiment as a one-piece casting.

The guide angle 1 has two legs 2 and 3, which emanate from the common corner region 4. The corner region is made of full material and has a relation to the inner surfaces 5 of the two legs raised arcuate support and guide surface 8, which open in the guide direction for both legs through beveled surfaces 8a and 8b in the legs. The guide angle 1 provides a total of three contiguous support and guide areas 10a, 10b (relative to the two legs) and 10c (in the region of the corner 4). Along these regions, two opposing rows of uprising supporting and guiding pieces 6 and 7 are respectively arranged at a distance from the side edges 2a, 3a of the angle. The support pieces 6 have on the sides facing each other at a distance from the inner surface of the angle guide slots 6a. In the corner region of the upstanding guide pieces 7 are arranged, which form in its upper region inwardly projecting hook-shaped projections 7a, the underside together with the arcuate guide surface 8 form a guide channel for the band, which opens at its transition ends to the legs at the same height, in which the plane of the guide slots 6a lies.

It can be seen that the guide pieces 7 are offset in the corner region in the two opposite rows against each other or arranged on a gap. At least two guide pieces 7 are found in each row in the corner area; through the gap arrangement can be arranged on one side more than on the other side.

Also in the region of the legs, the guide pieces of the opposite rows are offset from each other or arranged on a gap. The width 52 is, measured in the guide direction, approximately equal to the gap or the mutual distance 51 between two guide pieces 6 following one another in the same row.

In this way, for all three support and guide portions 10a, 10b and 10c continuous rows of guide pieces, which are uniformly and uniformly spaced and offset from the guide pieces of the opposite row are arranged in gap.

The one leg 2 has outside the associated support and guide surface 10a near its end a centrally disposed opening 12. The other leg 3 has in a similar region of this leg a towering in the angular range Guide piece 13, which is also centrally located and has a through opening 13a. Furthermore, at the ends of the legs relative to the inner surface 5 of the legs outwardly stepped staggered connecting pieces 16,17 are provided.

With the guide piece 1 after FIG. 1 can be easily assembled a corner drive. The parts of such are in FIG. 2 shown. In the illustrated embodiment, the forces-transmitting band 30 of three bands 30a, 30b and 30c, which are dimensioned differently to a predetermined extent slightly different in length and at their ends have openings 31 and 32 for riveting with coupling pieces 20 and 21 respectively. Each coupling piece has a rivet end 20b, 21b and a coupling end 20a or 21a for a connecting rod to be connected. Furthermore, each coupling piece over a part of its length on a guide slot 20c and 21c.

In the FIG. 2 parts shown are in FIG. 3 shown in section and form a mounted corner drive 50th Like out FIG. 3 can be seen, the one leg 3 in the support and guide portion 10b has a centrally disposed opening 14, the meaning of which will be explained in more detail below.

FIG. 4 shows the corner drive in the mounted state in side view. The moving parts are in the direction indicated by the arrow end position. FIG. 5 shows a look - related to FIG. 4 - from above. It can be seen hidden by the band 30 indicated the disposed in the leg 3 opening 14. Further, it can be seen that the longitudinal slot 21c of the coupling piece 21 in the in FIG. 4 shown position abuts with its end on the guide piece 13.

In the FIGS. 5a to 5c Sections are shown by the leg 3, in the in FIG. 5 Planned levels G, H and J. The illustration serves to illustrate the very simple assembly of a corner deflection by means of the guide angle. 1

For assembly, the first of one or more, for example, from three bands according to FIG. 2 formed band package (also: band package) riveted by means of the rivet attachment 20 b of the coupling piece 20 to the coupling piece 20. Thereafter, the opposite ends of the band 30 are inserted from the end of the leg 2 of the guide angle 1 forth in the support and guide portion 10 a between the guide pieces 6 and inserted over the support and guide portion 10 c of the corner portion 4 in the portion 10 b of the angle 3, and although so far that the rivet 21b of the other coupling piece 21, which has been threaded with its guide slot 21c on the guide projection 13, can engage in the opening 31 of the belt or tape package and is brought into engagement with this hole. This position is in FIG. 5a shown, cut GG.

Then the unit of the two coupling pieces 20,21 and the band within the guide angle is shifted so that the rivet 21b of the coupling piece 21 with the opening 14 in the leg 3 of the guide angle comes into alignment, as in FIG. 5b is shown, section HH.

Then, with a suitable tool, the rivet 21 on the back of the band is deformed accordingly to obtain a fixed rivet connection between the coupling piece 21 and the band 30 also at this end of the band. The riveted state is off FIG. 5c recognizable as 21b. Thus, the assembly of the elements of the corner 50 is already completed.

It can be seen that in total only a few parts and above all a few assembly steps are needed. The band 30 is reliably guided in the guide angle against any bending out, even under load, without the band edges being subject to excessive friction.

By the design of the guide pieces 6 and 7 and their arrangement is achieved that over the entire length of the tape the tape is held at least on one edge side in the guide.

The mutually offset guide pieces 6 and 7 ensure that the guide angle can be produced as a casting and easy removal of the cast piece is ensured in the corner 4. The training ensures that the Eckumlenkung is relatively smooth and therefore the transmission requires only correspondingly lower actuation forces.

The invention relates to a guide angle for a bendable band (30) for transmitting cornering power (push and / or pull movements) at a corner drive (50). It comprises three support and guide areas (10a, 10b, 10c). In the corner region (4) and at least at part lengths of the two legs (2, 3) of the guide angle (1) starting from the corner region. On both sides of all three support sections run rows of spaced guide pieces (6,7) for the bendable band (30), which protrude from inner surfaces (5,8) of the two legs and the corner region.
