EP2837762B1 - Belt assembly for doors, windows and similar - Google Patents

Description

The invention relates to a hinge arrangement for doors, windows and the like, with a fixed frame and a sash, which are connected to one another pivotably about a hinge axis by means of bands, each of which has a frame hinge part attached to a fastening wall of the fixed frame and a hinge part attached to a fastening wall of the sash Include sash hinge part, with a projection protruding from the fastening walls of the frame and / or the sash, which is encompassed by the frame hinge part and / or the sash hinge part in a recess, and with fastening means for fastening the frame hinge part and / or the sash hinge part to the respective fastening wall .

Such a band arrangement is from DE 200 05 202 U1 known.

In this band arrangement, the fastening means comprise first fastening screws, which are designed as machine screws. They penetrate perforations in the respective hinge part and perforations in the fastening wall which are aligned with them and which are formed by the mutually facing walls of the sash and frame hollow chamber profiles. The holes are from the Arranged on the front of the profile behind insulating webs of the profile, so that the band parts protrude from the outside beyond the insulating webs.

The first fastening screws are screwed into threaded bores which are provided in fastening elements which are introduced from an open end face of the respective profile and engage behind the respective fastening wall.

Furthermore, second fastening screws are provided which are designed as self-tapping screws. These pass through corresponding bores in the respective hinge part and are screwed into associated holes in the fastening wall near the front surface in order to reduce the size of the lever arm by means of which forces are introduced into the profile by the band.

Although it has been shown that this hinge arrangement is characterized by a particularly secure fit of the hinge parts screwed in this way, it is disadvantageous that incorrect assembly can easily occur when the hinge parts are attached to the frame or the sash. After determining the correct position of the belts for the respective conditions, the belt parts must be manually held in position for the purpose of marking the points where holes for the fastening screws are required, which harbors the risk of incorrect positioning, for example due to unnoticed slipping. Or an additional drilling jig must be used, which is attached to the profile instead of the hinge part prior to its assembly and indicates the positions at which the perforations must be worked into the profile. Another disadvantage is that the bands can create cold bridges, via which heat can be conducted from the front to the rear side of the profile on the other side of the insulating webs.

From the EP 1 223 278 A1 a band arrangement is known, with a fastening plate which can be attached to a fastening rail in a height-adjustable manner by having bores into which screws extending parallel to the thread axis engage.

The DE 196 24 558 C1 shows a device for fastening hinge tabs of hinges to steel frames, in which a hinge tab has angular, slotted recesses, with which it can be pushed onto locking screws between two clamping plates and clamped. Adjustment is made using retaining screws that move the clamping plates relative to the frame.

The invention is therefore based on the object that from DE 200 05 202 U1 known band arrangement to improve the attachability of the bands and the formation of cold bridges.

This object is achieved by the belt arrangement reproduced in claim 1.

Because the fastening means of the hinge arrangement according to claim 2 comprise at least one clamping screw provided on the frame hinge part and / or the sash hinge part, which can be brought into operative connection with the projection, pre-assembly of the frame hinge part on the frame and / or the sash hinge part on the sash can thereby take place that the at least one clamping screw is tightened. In this preassembled state it can then be checked whether the locations of the attachment of the frame and / or sash hinge part lead to the desired position of the sash in the frame. In the case of the belt arrangement according to the invention, it is also advantageous that the clamp assembly according to the invention is suitable for compensating for manufacturing tolerances. For example, if - as known from the prior art - perforations for fastening means of straps are made in the frame and / or the sash before the frame and / or the sash is installed, deformations during installation or coatings applied later lead to the fact that the perforations in the hinge parts do not align with the perforations in the frame or the sash, which means that reworking is necessary. The clamped band can be used as a drilling jig in the event that, in addition to clamping, it is also to be fastened with the aid of fastening screws. The clamp assembly is such an effective attachment that in the event that the attachment to a multi-chamber profile with insulating rods is to take place, additional fastening behind the insulating bars can be dispensed with.

Furthermore, the clamp assembly enables a subsequent attachment of a band, for example between already preassembled bands when the end faces of the profile are already closed.

The fastening walls from which the projection protrudes can in principle be all walls of the frame or of the sash that are suitable for fastening the respective hinge part. So that the visual impression conveyed by the band arrangement is not impaired and the fastening means are not accessible from the outside when the sash is closed, the fastening walls are preferably the walls perpendicular to the frame and / or sash plane, i.e. those walls of the frame and of the wing which face each other when the wing is closed.

In this case, the frame hinge part and / or the sash hinge part preferably comprise a fastening leg which engages in a rebate area formed between the frame and the sash and on which the recess for engaging the extension is also provided.

So that the already spatially restricted rebate area is not unnecessarily restricted by the clamping screw, this is preferably designed as a stud screw which is provided in a threaded hole opening into the recess. The length of the stud screw is - particularly preferably - adapted to the prevailing conditions in such a way that in the clamped state it does not protrude or at least only slightly protrudes from the threaded hole into the rebate area.

In order to enable adjustment of the sash in the frame without the clamping screws having to be loosened, the frame hinge part and / or the sash hinge part are constructed in several parts according to the invention, a first hinge part comprising the clamping screw and a second hinge part perpendicular and / or parallel to the respective fastening wall can be fixed in different positions on the first part. Due to this measure, both an adjustment parallel to the wing surface in the direction of the hinge axis - also called "vertical adjustment" - and parallel to the wing plane perpendicular to the hinge axis - also called "horizontal adjustment" - is possible with the clamping screw tightened.

The horizontal adjustability can - particularly preferably - be realized in that the first hinge part and the second hinge part have mutually facing first contact surfaces which run approximately parallel to the fastening wall and which can be positioned at different distances from one another.

To this end, a spacer element that can be inserted between the contact surfaces of the first and second hinge parts can be provided. To change the distance between the first contact surfaces, either spacer elements of different dimensions or a plurality of which can then be inserted in different numbers can be provided.

In order to bring about a flat introduction of the forces from the second into the first hinge part, it is advantageous to design the spacer elements as spacer plates that lie flat against the first contact surfaces.

To constructively implement the vertical adjustment, the first hinge part and the second hinge part according to the invention have second contact surfaces which face one another and run approximately perpendicular to the fastening wall with a normal approximately parallel to the hinge axis, the spacing of which in turn is variable.

According to the invention, the distance between the second contact surfaces can be varied continuously if the second contact surfaces are formed by a shank end of a stud bolt provided in a threaded hole extending approximately parallel to the hinge axis, preferably in the first hinge part, and a narrow side of the preferably second hinge part. About the relative displacement between the first and the second band part with simultaneous fixability According to the invention, at least one threaded hole is provided in the first band part, in the second band part an elongated hole that can be brought into overlap with the threaded hole, the longitudinal direction of which runs parallel to the hinge axis, and a cap screw that penetrates the elongated hole and is screwed into the threaded hole is provided according to the invention which the second band part can be clamped against the first band part. For horizontal adjustment, the at least one clamping screw must then be loosened to such an extent that the two hinge parts can be displaced relative to one another by actuating the adjusting screw. After finding the desired adjustment position, it is fixed by retightening the at least one clamping screw.

Depending on the load on the belt arrangement to be expected during use, fastening the belt parts with the aid of the clamping screws may already be sufficient. However, a further development of the hinge arrangement according to the invention is particularly preferred in which the fastening means additionally comprise head screws which are screwed transversely to the fastening walls through the frame and / or sash hinge parts into the stationary frame and / or the sash.

If the stationary frame and / or the wing cover frame profiles designed as hollow profiles, the head screws are preferably designed as self-tapping screws which are screwed into the hollow profile walls.

The load-bearing capacity of the fastening can be increased if - as is particularly preferred - head screws are provided whose axis is approximately perpendicular to the fastening wall and those which are inclined from the perpendicular to the fastening wall, preferably by about 30 ° to 45 °.

the same band arrangement in one Fig. 1 corresponding view with the sash closed.

The hinge arrangement, denoted as a whole by 100 in the drawing, is used to pivot a sash F, of which only a section of a sash profile 1 is shown, on a frame profile 2 of a stationary frame R. The frame profiles 1, 2 are designed as hollow profiles.

The belt arrangement 100 comprises a belt 3, which is designed as a so-called roller belt. It comprises hinge parts 4, 5 which receive a hinge pin 6 defining the hinge axis S. The hinge parts 4, 5 are arranged on the outside of the profiles 1, 2 close to their front wall 7, 8, which is located in a common plane V when the sash F is closed (cf. Fig. 3 ). The wing 8 can around the hinge pin 6 according to the in Fig. 3 opening side located above in the direction of arrow P, for example in the in Fig. 2 reproduced position can be pivoted.

How in particular turn out Fig. 3 can be seen, the two profiles 1, 2 are designed such that a rebate area 9 remains between them.

The vertically superimposed hinge parts 4, 5 of the belt 3, of which in Fig. 2 and 3 only the wing hinge part 4 can be seen, have fastening legs 10, 11 on their rear side facing the wing F or the frame R, which engage into the interior of the rebate area 9 through a shadow groove 12 between the profiles 1, 2 (cf. in particular Fig. 3 ). The fastening leg 10 is angled inside the rebate area 9 under the rebate part 13 in the direction of the sash profile 1 and ends in a widened area 14, the top side of which facing the sash profile 1 forms a first contact surface 15 of a second hinge part 16. The first hinge part 17, which together with the second hinge part 16 and the hinge part 4 forms the leaf hinge part 18, lies on the the fastening wall 19 forming the profile wall which lies opposite the fastening wall of the frame when the sash is closed. The contact side of the first band part 17 is pierced by a recess 21 into which a projection 22 extending vertically from the fastening wall 19 protrudes.

In the recess 22 opens into a Fig. 3 Threaded bore 23, indicated only by dashed lines, into which a clamping screw 24 designed as a stud screw is screwed. It is supported with its front end in the screwing-in direction on a surface of the projection 22 that is perpendicular to the fastening wall 19, engaging behind an according to FIG Fig. 3 downward bend 25 of the projection 22.

How out Fig. 3 becomes apparent, the frictional connection achieved with the help of the clamping screw 24 causes the first hinge part 17 to be fixed to the sash profile 1. To stabilize the fixing against higher loads, two pairs of cap screws 26, 27 are also provided, which are designed as self-tapping screws . In the Fig. 3 Head screw 26 of the upper pair shown further above penetrates a hole not shown in the drawing perpendicular to the fastening wall 19, its thread being in operative connection with a perforation in the fastening wall 19. The head screw 27 underneath is screwed in through a correspondingly aligned bore in the first hinge part 17, likewise not visible in the drawing, at an angle α to the perpendicular of the fastening wall 19, which in the illustrated embodiment is approximately 45 °.

The second hinge part 16 is connected to the first hinge part 17 with the aid of fastening screws 28 designed as head screws with machine thread, which are screwed into threaded bores incorporated in the first hinge part 17, which cannot be seen in the drawing. For this purpose, the fastening screws 28 penetrate the second hinge part 16 in elongated openings 29. A plate-shaped spacer element 31 is inserted between the first contact surface 15 of the second band part 16 and the opposite, first contact surface 30 of the first band part 17. The spacer element 31 can be replaced by another with a different thickness to adjust the distance between the wing F and the frame R perpendicular to the hinge axis S, the so-called "horizontal adjustment". Or the number of inserted spacer elements 31 is changed.

To adjust the sash relative to the frame in the direction of the hinge axis, the "vertical adjustment", the second hinge part 16 can be displaced relative to the first hinge part 17 in the longitudinal direction of the elongated openings 29 after loosening the fastening screws 28. In order to be able to undertake a sensitive, controlled adjustment, an adjusting screw 32 designed as a stud screw is screwed into the first hinge part 17 in a threaded hole not shown in the drawing. The front in screw-in direction, in Fig. 1 The upper end of the adjusting screw 32 forms a second contact surface 33 of the first hinge part, which rests against a second contact surface 34 of the second hinge part 16.

How out Fig. 1 becomes obvious, turning the adjusting screw 32 leads to a raising or lowering of the second hinge part 16 relative to the first hinge part 17, provided that the fastening screws 28 are sufficiently loosened.

As in Fig. 1 As can also be seen, the first hinge part 17 above the second hinge part 16 has a corresponding design with an adjusting screw 32 and second contact surfaces 33, 34. Due to this measure, it is on the one hand possible to use the sash hinge part 18 without modification for both the right and left hinged sashes, on the other hand, the second hinge part 16 can be additionally fixed with respect to the first hinge part 17 by using the upper one after reaching the desired adjustment position Adjusting screw 32 is tightened.

In order to adjust the second hinge part 16 to the first hinge part 17 also in the one running parallel to the fastening wall and perpendicular to the hinge axis S. To be able to make direction, the openings 29 are made so wide that there is sufficient play for a relative displacement even perpendicular to their longitudinal extension to the fastening screw 28. On the plate-shaped spacer element, on the side facing the second hinge part 16, a projection 41 is provided which can optionally be introduced into one of a plurality of recesses 42 provided in the second hinge part 16. In Fig. 3 the extreme position of the second hinge part 16 is shown, in which the hinge axis S has the maximum distance in front of the front side 7.

In principle, it is possible for the hinge part 5 and the frame hinge part 35 comprising the fastening leg 11 to configure the sash hinge part 18 in a corresponding manner. However, since the adjustability in the vertical and horizontal direction on the sash hinge part is usually sufficient to adjust the sash in the frame, the fastening leg is formed in one piece in the frame hinge part 35 of the hinge arrangement 100. The attachment to the frame profile 2, which also comprises a projection 36 protruding vertically from the attachment wall 20 and protruding into a recess 37, is carried out in the same way by means of a clamping screw 38 and cap screws 39, 49 as the above-described attachment of the first hinge part 17 of the Sash hinge part 18 on the sash profile 1. <b><u> Tag List :</u></b> 100 Band arrangement 31 Spacer element 1 Sash profile 32 Adjusting screw 2 Frame profile 33 second contact surface 3 tape 34 second contact surface 4th Hinge part 35 Frame hinge part 5 Hinge part 36 head Start 6 Hinge pin 37 Recess 7th Front wall 38 Clamping screw 8th Front wall 39 Cap screw 9 Folding area 40 Cap screw 10 Mounting leg 41 head Start 11 Mounting leg 42 Hopper 12 Shadow groove F. wing 13th Folded part R. frame 14th Area V level 15th first contact surface S.
