Abstract

Tabs on the hinge plate (10) and rail clips are projections which can penetrate into the top surface of the window or door leaf frames (11).

Description

The claims relate to a door or window hinge, with a struck on a fixed frame Frame hinge part, which articulates by means of a pivot axis a wing hinge part is connected, the one on a sash horizontally slidable hinge flap has that with Help a shift-resistant clamping plate vertically positive supported and can be clamped to the sash.

A door hinge with the aforementioned features is general (see for example EP-A-0837207 or DE-U-29718528). The clamping plate is fastened with screws, which in engage the sash and the clamping plate and the between this and the sash arranged hinge tabs press against the sash. A horizontal shift Bandlappens takes place, for example, overcoming the achieved with the clamping plate and its mounting screws Clamping forces. The clamping plate passes through the hinge flap with a positioning pin and the hinge tab is because of ensuring horizontal mobility with one Pass-through slot equipped by it from the punch-through bolt vertically positively supported. This support However, it is subject to tolerances, as well as a support the band tab by the clamping plate, the fixing screws both have tolerances to the clamping plate can, as well as tolerances for hingeing. Therefore and because Do not use the fixing screws with the maximum possible tightening torque can be tightened, namely horizontal It may happen to allow for displacements of the hinge a slipping of the wing band on the sash come, especially to a lowering. It results in a from the horizontal deviating inclination of the wing band, which may be low, the additional burden of the swivel joint leads and also misalignments of the wing can result. The position of the wing in the fixed frame can be changed so that malfunction are possible, for example by incorrect sealing gaskets.

In contrast, the invention is based on the object to improve a band with the aforementioned features so that a lowering of the wing strip on the sash excluded becomes.

This object is achieved in that the hinge flap and / or the clamping plate in the surface of the sash has or have penetratable projections and that the projections have a penetration slope at least at one longitudinal end.

For the invention it is important that the band projections that protrudes into the surface of the sash can penetrate. Such a design of the band is particular designed for doors and windows whose sash frames made of plastic, but in any case also a material, in the projections of the hinge or the clamping plate can penetrate. Penetrated projections cause one very advantageous vertical positive locking, namely independent tolerances of the fasteners of the hinge or the clamping plate is. Once selected position of Wing hinge part on the sash hinge frame can then only horizontally changed, but not vertically. An unintentional Lowering the wing strap is excluded.

It is particularly advantageous to the arrangement of Projections on the formation of the fastening means of the leaf hinge part vote. In that sense, the band can do that be formed so that the clamping plate on the frame side rests on the hinge plate and on the casement with fixing screws is set, which the hinge tab by the horizontal slots pass through, and that the tabs in the area the horizontal slots are present. The projections Therefore, support the hinge plate near the mounting screws from. This results in no or only small lifting arms, which act on the protrusions and try this from their positive engagement with the casement too bring. This results in an improved load capacity of a provided with a clamping plate leaf hinge part.

An advantageous embodiment of the tape is given when the projections on the voltage applied to the casement bottom wall the hinge are arranged. The arrangement of the projections between the part to be fastened, namely the hinge flap and the supporting part, namely the sash an immediate positive engagement of the to be coupled together parts. It is not a mediation of others Parts of the vertical positive connection required. On the positioning of the hinge on the casement is immediate. A vertical slippage of the hinge on the wing frame can by appropriate design of the projections be excluded.

A very good positioning of the wing hinge part on Wing frame arises but when projections on / in Horizontal slots of the hinge engage the positioning tabs the clamping plate are arranged. It will then excluded in any case that tolerances in the Range of mounting screws on a positioning of the Bandlappens or the Flügelbandteils impact because a vertical displacement of the clamping plate on the casement because of the direct attack of the projections on the casement is excluded. On the other hand, those between the Clamping plate and the wing hinge part or the hinge strap existing Tolerances kept in sufficiently small limits being supportive, a non-lowering construction between the hinge plate and the clamping plate is possible.

To provide numerous form-fitting producing protrusions, the one correspondingly increased security against Slipping on the wing frame form, the band can be formed be that projections vertically above and below a horizontal slot of the hinge flap are arranged. It results in particular in a conventional training with several horizontal slots a multiple support of the Wing hinge part on the wing frame, wherein the respective penetration depths because of the large number can be kept low.

The above-described training with numerous indentations is possible even if the tape is so formed is that vertically above and below a punch-through hole a positioning projection penetratable projections are arranged. Such training is particular advantageous if the hinge flap formed underneath smooth shall be. But it is also possible namely, if at a wing frame side with projections provided hinge tabs further projections for the preparation of vertical form closures are to be used.

The formation of the penetratable projections can in particular in view of the fact that a good vertical Form fit is to produce. In that sense it is advantageous to form the band so that the projections are horizontal are elongated. The horizontal longitudinal extent the projections ensures good support in vertical Direction.

The band can be developed to the effect that the Projections are formed like a blade. The cutting-like Formation of the projections facilitates penetration into the material of the sash. It also comes the horizontal adjustment the wing hinge part on the wing frame, because they cut in an appropriate design the projections in the material of the sash lightened.

The above-described facilitation of the intrusion of Projections into the material of the casement is in particular given horizontal displacements then when the projections at least at one longitudinal end a Eindringschräge exhibit. The penetration slope acts under vertical pressure on the sash so that a cutting takes place, associated with a lateral displacement of the sash material. Even with larger clamping forces is an adjustment the wing hinge part still possible.

Conveniently, the band is formed so that the Projections at least schwenkachsenabseitig with a maximum Adjustment of the hinge overlapping distance are arranged by a hinge tab end. This excludes that the leaf hinge part is adjusted and by Displacement of his band flap. Indentation notches in the casement become visible.

Fig. 1 shows the cross section of a fixed frame 11 of a door. In the frame 11 is a door with a door hinge 10 hinged. The door hinge 10 is formed so that a Sash frame 16 of the door on the fixed frame 11 at closed wing arranged in the illustrated manner sealed is and verschwengt in the direction of arrow 26 can. Both frames 11, 16 are formed as hollow profiles, which are made of plastic. In a central cavity 27, 28 of the frame 11 are each a metallic Stiffening profile, namely a pipe with which the required Stiffness of the frame spars is improved. The stiffening profiles also serve for improved attachment of parts of the door hinge 10.

The door hinge 10 consists of a frame hinge part 13, the struck on the fixed frame 11, and from a Wing hinge part 15, which is posted on the sash 16. The frame hinge part 13 has a base 13 'by a Paßstift 30 is attached. The dowel 30 ensures in Connection with a height-adjusted hole of the frame 11, the desired height position of the frame hinge part 13th

Its attachment is done with mounting screws, not shown, the screwed parallel to the dowel 30 are. The base 13 'of the frame hinge part 13 is with a frame projecting outwardly eye 31 provided in the one end of a pivot axis 14 is inserted. The other End of the pivot axis 14 serves the articulated coupling of a Wing hinge part 15.

The wing hinge part 15 consists essentially of a Band tab 17, which is flat on the surface 16 'of the sash 16 rests. The hinge flap 17 has two parallel Side web 32, the ends 32 'eyes 33 for receiving a Form end of the pivot axis 14. In these eyes 33 is the Swivel axis 14 mounted with a sleeve 34 which is an eccentric Receiving bore for the pivot axis 14 has. Moderate angle Adjustments of the sleeve 34 lead due to fixed Swivel axis 14 to the fact that the wing hinge part 15 accordingly is adjusted. The wing hinge part 15 is thus perpendicular to Frame level and / or horizontally adjusted in the frame plane, in order to 16 accordingly due to its attachment to the sash To achieve adjustments of the wing, the Deformation of the function are necessary, for example for Setting the sealing function of the sash 16 in With respect to the fixed frame 11.

The attachment of the band 17 on the sash 16 takes place by means of a clamping plate 18, which has through-holes 23, see Fig.4a, by the fastening screws 20th are screwed into the sash 16. Because the clamping plate 18 frame on the hinge tab 17 between the Seitstegen 32 is seconded, see Figure 4, introduces Tightening the fastening screws 20 causes the hinge tab 17 pressed against the surface 16 'and thus on the sash 16 is attached.

The attachment of the hinge 17 on the sash 16 must done so that a horizontal adjustment of the hinge 17 is possible. For this purpose, the fixing screws 20 either be solved, or they will from the outset not tightened with the maximum tightening torque, so that the horizontal adjustment of the hinge 17 under Overcoming any clamping forces is possible. One such Adjustment is an adjustment 35, the in itself is known. An adjusting screw 36 engages with her Shaft 37 in the shaft correspondingly shaped recesses 38th the clamping plate 18 on the one hand and the hinge strap 17 on the other hand, compare Fig.4a, 4b. On the threaded Screw shaft is an adjusting nut 39, the in a not shown recess of the hinge plate 17th invisibly engaged. In addition, the head 36 'of the set screw 36 in a not shown recess of the Bandlappens 17 rotatable, but arranged axially immovable. As a result, performs an adjustment of the adjusting screw 36th by applying the screw head 36 ', for example with an Allen key to that of the adjusting nut 39 supporting adjusting screw 36 axially adjusted and doing in accordance with the hinge tab 17 entrains. Relocation the hinge 17 is carried out depending on the turning of the adjusting screw 36 in one direction or the other Adjusting screw 36 so that the fixed with the hinge tab 17th connected sash 16 the fixed frame 11 of his the sealing end face either approximated or it is removed. With the adjustment 35 can therefore an exclusively horizontal adjustment of the door leaf be achieved.

The door wields a considerable amount according to its weight Load on the door hinge 10 off. Especially at prolonged use of the door is to be feared that the clamping load of the hinge 17 is not sufficient to slipping on the surface 16 'to prevent. It is as a result a dowel 40 is present, which is fixed to the clamping plate 18 is connected and according to Figure 1 in the sash 16 intervenes. In this case, the hinge tab 17 of the dowel pin 40 in a slot 41 passes through, arranged horizontally is and a horizontal adjustment of the hinge 17 allowed. Such a configuration is conventional and intended cause the hinge tab 17 against vertical loads is supported, so that so the sash 16 on the dowel 40 additional supports and vertical relative movements between the hinge flap 17 and the sash 16 does not occur can. However, it has been proven that such Design is not sufficient. Due to structural tolerances and by tolerances in the field of fastening screws 20, especially at non-maximum torques this fastening screws 20 occur relative sieges the hinge 17 on, so that the door is an undesirable Position relative to the detecting frame 11 occupies. Such a configuration is therefore in the illustrations the hinge 17 of the Fig.2 not shown.

The horizontally displaceable hinge flap 17 is rather provided with projections 19 which in the material or in the Surface 16 'of the sash 16 are penetrated. The Projections 19 are one-storey on the surface 16 'resting bottom wall 21 of the hinge 17. Sie are thus produced at the same time with the hinge flap 17, the for example by injection molding of a suitable metal will be produced. The position of the projections 19 in Determined with respect to the fastening means of the bottom flap 17. This has horizontal slots 17 'for the passage of the Fixing screws 20 with which the clamping plate 18 verschiebefest is attached. The horizontal slots 17 'are 2 in the push-through area of the fastening screws 20 matched to the outside diameter. Close the horizontal slots 17 'are vertically above and below a horizontal slot 17 'each have a projection 19. With two horizontal slots 17 'result accordingly a total of four projections 19. With these, the hinge flap 17 in the attachment of the wing hinge part 15 exactly in held the desired position without the risk slipping would be particularly large. Be the fixing screws 20 tightened so that the clamping plate 18 on presses the hinge tab 17, penetrate the projections (19) in the Material of the sash 16 and prevent in particular at full surface conditioning of the bottom wall 21 on the surface 16 'any vertical adjustment.

Similarly, projections 19 acting on the Clamping plate 18 are arranged, more precisely at the positioning projections 22. The positioning projections 22 are, for example horizontally extending ribs, which are in horizontal slots 17 '' of the hinge 17 are inserted. The positioning projections 22 jump the thickness of the hinge 17 correspondingly far in front, so that the existing projections on you 19 protrude beyond the bottom wall 21 of the hinge 17. Are fixing screws in through holes of Positioning projections 22 screwed, so the plate 18th pulled against the sash 16 and it clamps according to Figure 4 shows the hinge tab 17 on the surface 16 'of the sash 16 firmly. The projections 19 already prevent the Attach the wing hinge part 15 on the frame 11 slipping and after their penetration into the material of the sash 16 is a vertical slippage also because of by the Eindrigen produced positive connection vertically or parallel to the pivot axis 14 impossible.

With regard to the horizontal adjustability of the Bandlappens 17 are the projections 19 in a special way formed, so apart from a horizontal longitudinal extent, parallel to the horizontal slots 17 ', 17' ' or horizontally aligned. In this regard, Fig. 3a shows an embodiment of a projection 19 which at both longitudinal ends each has a penetration 25. This indentation 25 causes a horizontal adjustment of the hinge 17, the cutting-like projections 19 knife-like penetrate into the material of the sash 16 and so the horizontal adjustment in the sense of a favor reduced adjustment effort. The two Eindringschrägen 25 each act in one of the two adjustment directions.

In order to prevent the penetration of the projections 19 in the material of To facilitate sash 16, the projections 19 formed like a blade. So you have a triangular Cross section with a wing frame side cutting edge, the even at low generated by the clamping plate 18 Contact forces allows penetration and thus already too Beginning of the fastening process ensures that the leaf hinge part 15 can not be moved vertically.

The arrangement of the projections 19 is made such that a horizontal adjustment of the hinge 17 not to a Visible can lead to deformations caused by penetration of the projections 19 were achieved. In terms of then the projections 19 are at a distance from the hinge tab ends seconded, at least at a distance to a hinge end 17 '' ', because here most likely deformations of the surface 16 'could be visible if the hinge tab 17th in Fig.1 is adjusted to the right. The distance is tuned to the maximum displacement 24 of the hinge 17, is therefore at least the same size or larger. The adjustment path 24 is shown in FIG. 1 by the slot length of the penetration slot 41 determined for the positioning pin 40.
