EP2504510B1 - Hinge assembly for doors, windows or the like - Google Patents

Description

The invention relates to a hinge arrangement for doors, windows and the like, with a fixed frame and a wing, which are pivotally connected to each other by means of hinges about a hinge axis, each of which is attached to a mounting wall of the fixed frame and a frame part attached to a mounting wall of the wing Sash hinge part, wherein a projection protrudes from the fastening walls of the frame and / or the wing, 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 the 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 band part and perforations in alignment with these in the fastening wall, which are formed by the mutually facing walls of sash and frame hollow chamber profiles. The perforations are from the Seen from the front of the profiles, arranged behind the insulating bars of the profile, so that the band parts protrude from the outside over the insulating bars.

The first fastening screws are screwed into threaded bores which are provided in fastening elements inserted from an open end face of the respective profile and engaging 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 band part and are screwed into associated holes in the fastening wall near the front surface in order to reduce the lever arm via the forces from the band being introduced into the profile.

Although it has been shown that this hinge arrangement is characterized by a particularly secure fit of the hinge-fastened hinge parts, it is disadvantageous, however, 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 straps for the respective circumstances, the strap parts must be held in position manually in order to mark the points at which perforations are required for the fastening screws, 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 band part before it is installed and indicates the positions at which the perforations have to be machined into the profile. It is also disadvantageous that the bridges can cause cold bridges, via which heat conduction from the front to the rear profile side can take place beyond the insulating webs.

A generic band arrangement is from the DE 26 24 278 A1 known and disclosed a band arrangement according to the preamble of claim 1. Its frame profile has a projection with a clamping surface extending parallel to the fastening surface of the frame profile. The band of this band arrangement comprises a fastening part with a recess which is provided for gripping around the projection. A sheet metal screw opens into the recess receiving bore. The front end of the self-tapping screw is supported on the clamping surface. To support the attachment to the projection, the frame profile has a sawtooth-like toothing on the attachment surface. A corresponding toothing on the frame part interacts with this toothing. The teeth are firmly pressed into each other by a further screw arranged perpendicular to the sheet metal screw, so that the band is fixed in two directions.

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

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

Due to the fact that the fastening means 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, the frame hinge part can be preassembled on the frame and / or the sash hinge part on the sash in that the at least a clamping screw is tightened. In this preassembled state, it can then be checked whether the locations of the attachment of the frame and / or wing hinge part lead to the desired position of the wing in the frame. Furthermore, it is advantageous in the belt arrangement according to the invention that the clamp assembly according to the invention is suitable for compensating for manufacturing tolerances. For example, if - as is known from the prior art - perforations for fasteners of strips are introduced into the frame and / or the wing before the frame and / or the wing are assembled, deformations during installation or coatings applied later on can be used lead that the perforations in the hinge parts do not align with the perforations in the frame or the sash, which means that reworking is required. The clamped band can be used as a drilling jig if, in addition to the clamping, fastening with the aid of fastening screws is also to be used. Also, the clamp assembly is such an effective attachment that in the event that the attachment to a multi-chamber profile with insulating rods, an additional fastening behind the insulating bars can be dispensed with on a regular basis.

Furthermore, the clamp assembly enables a band to be subsequently attached, for example between bands which have already been preassembled, if the end faces of the profile are already closed.

So that the visual impression conveyed by the hinge arrangement is not impaired and the fastening means are not accessible from the outside when the sash is closed, the fastening walls are the walls perpendicular to the frame and / or sash plane, i.e. those walls of the frame and the wing that face each other when the wing is closed.

The frame hinge part and / or the sash hinge part comprise a fastening leg which engages in a fold region formed between the frame and the sash and on which the recess for engaging the extension is also provided.

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

In order to enable an 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 preferably designed in several parts, a first hinge part encompassing the clamping screw and a second hinge part perpendicularly and / or parallel to the respective fastening wall can be fixed in different positions on the first part. Because of this measure, both an adjustment parallel to the wing surface in the direction of the hinge axis - also called "vertical adjustment" -, as well as parallel to the sash plane perpendicular to the hinge axis - also called "horizontal adjustment" - possible with the clamping screw tightened.

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

For this purpose, a spacer element that can be inserted between the contact surfaces of the first and the second band part can be provided. To change the spacing of the first contact surfaces from one another, either spacer elements of different dimensions or several, which can then be inserted in different numbers, can be provided.

In order to bring about the greatest possible introduction of the forces from the second into the first band part, it is advantageous to design the spacer elements as spacer plates lying flat against the first contact surfaces.

For constructive realization of the vertical adjustment, the first hinge part and the second hinge part preferably have mutually facing, approximately perpendicular to the fastening wall with a normal approximately parallel to the hinge axis, the second contact surfaces, the distance between which is in turn variable.

The distance between the second contact surfaces can - particularly preferably - be steplessly varied if the second contact surfaces are formed by a shaft end of a stud screw provided in an approximately parallel to the hinge axis, preferably in the first hinge part and a narrow side of the preferably second hinge part. In order to allow the relative displacement between the first and the second hinge part while the two hinge parts can be fixed to one another, there is preferably at least one threaded hole in the first hinge part, in the second hinge part an elongated hole which can be brought into overlap with the threaded hole and whose longitudinal direction runs parallel to the hinge axis, and one penetrating the slot, Provided in the threaded bore head screw, by means of 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 band parts can be displaced relative to one another by actuating the adjusting screw. After the desired adjustment position has been found, it is fixed by tightening the at least one clamping screw.

The fastening means additionally include cap screws which are screwed into the fixed frame and / or the wing transversely to the fastening walls through the frame and / or wing hinge parts.

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

The strength of the fastening can be increased if, as is particularly preferred, cap screws are provided, the axis of which is approximately perpendicular to the fastening wall and those which are inclined from the vertical to the fastening wall, preferably by approximately 30 ° to 45 °.

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

The hinge arrangement designated 100 in the drawing as a whole serves for the pivotable mounting of a wing F, of which only a section of one Sash frame profile 1 is shown, on a frame profile 2 of a fixed 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 which defines 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 wing F is closed (cf. Fig. 3 ). The wing 8 can around the hinge pin 6 after in Fig. 3 opening side located above in the direction of arrow P, for example in the in Fig. 2 reproduced position can be swung open.

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

The vertically superimposed hinge parts 4, 5 of the band 3, of which in Fig. 2 and 3rd only the wing hinge part 4 is recognizable, have on their rear side facing the wing F or the frame R fastening legs 10, 11 which engage through a shadow groove 12 between the profiles 1, 2 in the interior of the fold area 9 (cf. in particular Fig. 3 ). The fastening leg 10 is angled in the interior of the folding area 9 under the folding part 13 in the direction of the sash frame profile 1 and ends in a widened area 14, the upper side of which facing the sash frame profile 1 forms a first contact surface 15 of a second band part 16. The first hinge part 17, which together with the second hinge part 16 and the hinge part 4 forms the sash hinge part 18, lies against the profile wall forming the fastening wall 19, which is 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 which extends vertically from the fastening wall 19 projects.

One opens into the recess 21 Fig. 3 only indicated by dashed lines threaded bore 23 into which a clamping screw 24 designed as a stud screw is screwed. It is supported by one with its front end in the direction of insertion to the mounting wall 19 vertical surface of the projection 22 under the grip of a Fig. 3 downward bend 25 of the projection 22.

How out Fig. 3 becomes sensible, the frictional connection achieved with the aid of the clamping screw 24 causes the first hinge part 17 to be fixed on the casement profile 1. In order to stabilize the fixing even 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 above passes through a bore, 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 underlying cap screw 27 is screwed in through a correspondingly aligned, likewise not recognizable in the drawing hole in the first band part 17 at an angle α to the vertical of the mounting wall 19, which is approximately 45 ° in the illustrated embodiment.

The second hinge part 16 is connected to the first hinge part 17 with the aid of fastening screws 28 designed as cap screws with machine threads, which are screwed into threaded bores which are not recognizable in the drawing and are machined into the first hinge part 17. For this purpose, the fastening screws 28 penetrate the second band 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 31 can be replaced to adjust the distance of the wing F from the frame R perpendicular to the hinge axis S, the so-called "horizontal adjustment" for another with different thickness. Or the number of inserted spacer elements 31 is changed.

To adjust the wing relative to the frame in the direction of the hinge axis, the "vertical adjustment", the second hinge part 16 can be loosened compared to the first hinge part 17 in the longitudinal direction of the elongated openings 29 the fastening screws 28 are shifted. In order to be able to carry out a sensitive, controlled adjustment, an adjusting screw 32 designed as a stud screw is screwed into the first band part 17 in a threaded bore not shown in the drawing. The front in the direction of rotation, in Fig. 1 The end of the set screw 32 lying at the top forms a second contact surface 33 of the first band part, which lies against a second contact surface 34 of the second band part 16.

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

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

In order to be able to adjust the second hinge part 16 to the first hinge part 17 also in the direction running parallel to the fastening wall and perpendicular to the hinge axis S, the openings 29 are so wide that even perpendicular to their longitudinal extension to the fastening screw 28 there is sufficient play for one Relative shift exists. On the plate-shaped spacer element, on the side facing the second band part 16, a projection 41 is provided, which can optionally be introduced into one of several troughs 42 provided in the second band part 16. In Fig. 3 the extreme position of the second band 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 design the wing hinge part 18 in a corresponding manner. However, since usually the adjustability in vertical and horizontal direction on the sash hinge part is sufficient for adjusting 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 likewise comprises a projection 36 projecting vertically from the attachment wall 20 and projecting 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 attachment of the first band part 17 of the above described Sash hinge part 18 on the sash profile 1. <b><u>References :://></b> 100 Band arrangement 31 Spacer 1 Casement profile 32 Set screw 2nd Frame profile 33 second contact surface 3rd tape 34 second contact surface 4th Hinge part 35 Frame hinge part 5 Hinge part 36 head Start 6 Hinge pin 37 Recess 7 Front wall 38 Clamping screw 8th Front wall 39 Cap screw 9 Fold area 40 Cap screw 10 Mounting leg 41 head Start 11 Mounting leg 42 Hopper 12th Shadow groove F wing 13 Folded part R frame 14 Area V level 15 first contact surface S Hinge axis 16 second part of the band α angle 17th first band part P arrow 18th Wing hinge part 19th Fortification wall 20 Fortification wall 21st Recess 22 head Start 23 Tapped hole 24th Clamping screw 25th Bend 26 Cap screw 27 Cap screw 28 Mounting screws 29 Breakthroughs 30th first contact surface
