Abstract

The invention relates to a door or window hinge plate (10), comprising a flat hinge strap (12) which is located on the wing (11) of the door or window and whose edges project parallel to one another, a bearing bolt (15) being arranged at one end of each of said edges. Said bearing bolt (15) is held tightly from behind by a wall section (16) of the hinge strap (12). The inventive hinge plate also comprises a clamping plate (17) which clamps the hinge strap (12) on the wing (11) by activating fastening means which engage in said wing (11), as well as setting means (19) which displace the hinge strap (12) relatively between its edges when the hinge strap is not clamped in place, and a protective cap (20) which encompasses the hinge strap (12) and its clamping plate (17), and the bearing bolt (15). In order to provide stabilisation, especially with large wing loads, the hinge plate (10) is configured so that the hinge strap (12) has a cavity in its wall section (16) which corresponds to the circumference of the bearing bolt (15), the bearing bolt being accommodated in said cavity either directly or via a bearing sleeve (22).

Description

Door or window hinge

The invention relates to a door or window hinge with the features of the preamble of claim 1.

A door or window hinge with the aforementioned features is known from EP-A-0 659 968. The hinge plate and its edges form a U-shaped profile, the wall section of the hinge plate reaching behind the bearing pin being necessary in order to position a clamping screw here which has to be screwed into the circumferential groove in order to fix the bearing pin. This configuration of the hinge has the consequence that the bearing pin is located comparatively far from the wing or in front of the hinge in order to create the required space for the wall section of the hinge between the hinge pin and the wing. The comparatively distant arrangement of the bearing pin from the wing leads to considerable loads on the belt, particularly when the wing is open and the wing weights are large, so that its area of use is correspondingly restricted.

From DE-U-296 22 639 a generic band is known in which the bearing pin is arranged closer to the wing in comparison to the previously described band. In this band, the band tab is shorter, so it does not engage behind the bearing pin, which is held only by freely projecting edges of the band tab. This well-known hinge is also not suitable for larger wing loads because the free protruding edges of the ligament flap can become unstable when subjected to greater loads.

The invention is therefore based on the object of improving a door or window hinge with the features mentioned at the outset so that it remains stable, in particular in the case of large sash loads.

This object is achieved in that the band tab has in its wall section a recess which is adapted to the circumference of the bearing pin and in which the bearing pin is arranged directly or by means of a bearing sleeve.

It is essential for the invention that the bearing pin can be positioned comparatively close to the wing and that the edges of the hinge flap are stabilized by the wing itself. Such positioning is achieved through the recess in which the bearing pin is arranged. If the band is designed to avoid friction with bearing sleeves in which the bearing pin engages or which surround the bearing pin, such a bearing sleeve can also be arranged in the recess, so that the bearing pin engages indirectly in the recess.

So that the hinge flap can extend as far as possible in its longitudinal direction, which means a correspondingly improved stabilization of the edges holding the bearing pin, the band can be formed so that the recess is partially cylindrical and engages over the bearing pin beyond its center. The partially cylindrical design of the recess results in an optimal adaptation to the bearing pin or to its bearing sleeve and thus minimal loss of space. The overlapping of the bearing pin beyond its center causes a correspondingly enlarged support of the bearing pin with correspondingly improved guidance and stabilization of the edges of the hinge flap.

It is expedient if the recess of the band tab is stepless from the contact surface for the clamping plate extends. As a result, the tape can move in the longitudinal direction. of the band flap be more compact.

The door or window hinge can be designed in such a way that the cover cap has a bend on the bearing pin side which is supported on the bearing pin and engages with an edge overlapping in a recess in a bearing block which can be attached to the fixed door or window frame. The support of the cover cap on the bearing pin or indirectly on its bearing sleeve serves on the one hand to fasten the cover cap, but can also be used to stabilize the band if the cover cap is also sufficiently firmly connected to the other components of the band. The overlapping edge engaging in a recess of the bearing block provides a seal of the band in the joint area and promotes the appearance of the band.

The door or window hinge can also be designed in such a way that the cover cap has a bend on the bearing pin side, to which a retaining tab engaging behind the hinge flap in the region of its recess is fastened. The retaining tab on the hinge plate is used to secure the cover cap in the bearing pin area by means of clamping. The elasticity of the material of the cover cap, which consists for example of an aluminum alloy, is used here.

The invention further relates to a door or window hinge with the features of the preamble of claim 6. A hinge with these features is known from DE-C-37 19 516. The known cover cap only covers the clamping plate and does not engage in the area of the bearing pin. It is therefore not able to stabilize the band in the area of the bearing pin and, moreover, is comparatively less burglarproof. This hinge is therefore also based on the above-mentioned object of achieving an improvement in that the hinge remains stable, in particular with large wing loads. This object is achieved in that the cover cap comprises the bearing eye between frame-side edge sections with a retaining tab which engages between the bearing eye and a bearing block which can be attached to the fixed door or window frame and clasps the bearing eye. In this case too, the bearing pin can be positioned comparatively close to the wing and the bearing eye stabilizes the edges or the frame-side edge sections. The holding tab engaging the bearing eye is used to fasten the cover cap in the bearing pin area by means of clamping and the cover cap in turn serves to stabilize the band in the area of the bearing pin, so that the bearing eye can be made comparatively thin-walled.

If the bearing eye is formed thickened on the retaining tab side, this serves to stabilize the band in the main load direction away from the fixed frame in order to prevent deformation of the bearing eye here.

The stabilization of the band in the area of the bearing pin can be promoted in that the bearing eye has a contact surface supporting the cover cap on the side of the holding tab.

It is advantageous to design the door or window hinge so that the hinge flap has only a fraction of its thickness in the region of its recess or a connection point with the bearing eye. As a result, it is possible to make the band correspondingly compact vertically to the frame level, which also contributes to increasing the resilience of the band. This also means that the bearing pin can be positioned closer to the wing.

A further stabilization of the band is possible because the frame-side edge sections of the band tab are thickened transversely to the bearing pin in the region of the recess or the bearing eye, compared to the edge sections present on the other side of the bearing pin. There is sufficient space on the conveyor belt for such thickening, because a Bearing block holding bearing anyway has room for its

Order on the fixed frame required.

The door or window hinge can also be designed such that the cover cap is U-shaped at its end facing away from the bearing pin and engages behind the hinge flap with one leg, and that a latching nose or latching rib hooking into the hinge flap is present on the rear leg. Such a U-like design of the cover cap is known from the aforementioned DE-U-296 22 639. However, the positioning of the known cover cap is not completely satisfactory. Such an improved positioning is achieved in that the cover cap has a latching lug or rib that hooks into the band tab. According to this improved positioning, an improved stabilization of the band can also be achieved by the cover cap, in particular if it is inserted between the edges of the band tab.

It is advantageous to design the band in such a way that the edge sections located in the region of the recess of the band tab or the bearing eye protrude beyond the adjacent edge edges. This enables the use of bearing bolts with larger diameters or the use of bearing sleeves is achieved without the diameter of the bearing bolts having to be reduced excessively. This configuration is particularly advantageous for heavy-duty belts.

A further advantageous embodiment is present when the edges of the hinge tab have deposits into which the edges of the cover cap are fitted with aligned outer surfaces of the cap. The cover cap fits comparatively precisely between the edges. As a result of this and as a result of the clasping of the hinge flap at both ends, the seat of the cover cap is stabilized, which accordingly stabilizes the entire hinge and is itself relatively difficult to remove, for example in the event of break-in attempts with hinges on the outside or on the outside of the window. The invention is illustrated with reference to the drawing

Exemplary embodiments explained. It shows:

Fig.la a longitudinal section through a door structure in the area of a hinge,

Fig. Lb is a sectional view similar to Fig.la for a door hinge with a differently designed cover cap, Fig. 2 is a plan view of a door hinge according to Fig.l with the cover cap shown partially broken away,

3 shows an enlarged longitudinal section through a band tab of a band of FIGS. 1 to 2, FIG. 4 shows a perspective illustration of a band tab provided with special edges with a cover cap arranged thereon to be assembled with the band tab, and FIG. la similar sectional view of a door hinge with a differently designed mounting of the bearing pin.

The door hinge 10 shown in the Fig.la, lb is struck on the one hand on a wing 11 and on the other hand on a fixed frame 27. Both frames are made, for example, of plastic and are provided in a central hollow chamber 35 or 36 with a reinforcement profile 37 or 38. The wing 11 can be pivoted in the direction of arrow 39 to open it. For this purpose, the band 10 is correspondingly articulated.

The band 10 has a bearing block 28 fixedly attached to the frame 27, which in a known manner has a bearing bolt 15 which extends parallel to the frame or door plane in accordance with FIG. 2 and at its upper end the articulated arrangement of a further one to the bearing block 28 Permitted bearing part that is attached to the wing 11. An essential component of this second bearing part is a hinge flap 12 which rests directly on the outer surface 11 'of the sash frame. The band tab 12 is fastened with a clamping plate 17, which in turn rests on the contact surface 12 ′ of the band tab 12. The clamping plate 17 is in the frame plane adjustable, as the inlet pin 40 shows, the one.

End sits firmly in the clamping plate 17 and engages with the other end in a hole in the frame 11. The clamping plate 17 has fastening means 18 in the form of fastening screws 41 shown in FIGS. 1, 2, which pass through elongated holes 42 in the hinge 12 and can be tightened so that the clamping plate 17 clamps the hinge 12 on the wing 11. There are several fastening means 18 or fastening screws per elongated hole 42, as shown in FIG. As a result, the band tab 12 can be adjusted in its longitudinal direction when the screws 41 are loosened. Such an adjustment serves to be able to make the horizontal adjustment of the sash 11 relative to the frame 27 which is required in the frame plane.

Adjustment means 19 in the form of an adjusting screw 43 and an adjusting nut 44 are used to adjust the hinge flap 12. Both are partly housed in recesses in the hinge flap 12 and partly in recesses in the clamping plate 17, so that the latter two lie flat on one another accordingly. The adjusting screw 43 engages with its head 43 ′ in a recess 45 of the hinge 12 and the adjusting screw 44 is fixed in a recess 45 of the clamping plate 17. The head 43 'of the adjusting screw 43 is provided with an internal polygonal recess, not shown, in which an adjusting key can engage. As a result of the adjusting nut 44 fixed in the clamping plate 17, rotation causes the screw head 43 'to move the hinge flap 12 between the clamping plate 17 and the wing 11. So that this displacement is not hindered by the adjusting nut 44, the hinge flap 12 is provided with a longitudinal slot 47 according to FIG.

The band tab 12 is provided with the edges 13 shown in FIG. 4 below, which project away from the window plane and have bearing bores 48 for the bearing pin 15 or its bearing sleeve 22. The bearing bores 48 are circular and are provided with semicircular extensions 49 which can be made to coincide with recesses 50 of the bearing sleeve 22 which are triangular in cross section, as shown in FIGS. In the through the recess 50 and the extension 49 jointly formed cross section, a locking part, not shown, is introduced, which can be part of the bolt cap 51 shown schematically in FIG. 2, for example. The locking part secures the angular position of the bearing sleeve 22. The FIGS. 1b, 1b show that the bearing sleeve 22 has a plurality of triangular recesses 50, which can each be brought into register with one of the extensions 49. The bearing sleeve 22 accordingly has numerous adjustment positions. From the Fig.la, lb it can be seen that the bearing pin 15 is eccentric with respect to the bearing sleeve 22. If the relative angular position of the bearing sleeve 22 is changed, the position of the bearing pin 15 changes correspondingly vertically to the frame 27. By adjusting the angular positions of the bearing sleeve 22, adjustment can accordingly take place vertically to the frame 27, namely a pressure adjustment of the wing 11.

The hinge flap 12 engages behind the bearing pin 15 and connects the wing-side edge sections 23 of the hinge flap 12 to one another. There is a corresponding stiffening of the band tab 12 in this area. The engaging wall section 16 of the band tab 12 is, however, provided with a recess 21 which, according to FIG. 3, is partially cylindrical. The recess 21 is adapted to the circumference of the bearing pin 15, as the identity of the radii of the bearing bore 48 and the recess 21 show. The wall section 16 engages behind the bearing pin 15 beyond its center, so that there is an encirclement of the bearing pin 15 of approximately 120 degrees. The enclosure extends into the immediate vicinity of the extension 49, so that there is a correspondingly large adjustability of the bearing sleeve 22 without having to take into account a special design of the wall section 16. The wall section 16 engages the hinge plate 12 so that its recess 21 extends continuously from the support surface 12 'intended for the clamping plate 17, so that the region 12''of the hinge plate 12 fully to stabilize the support of the bearing pin 15 or Bearing sleeve 12 is available. The wall section 16 is designed so that it over the

Support surface 12 '' 'of the band tab 12 protrudes. This is harmless with regard to a secure support of the hinge flap 12 on the wing 11 because the hinge flap engages in the bearing block 28 in this area, which here bridges the distance between the surface 11 'of the wing 11 and the frame 27.

For the same reason, it is advantageous to thicken the edge sections 23 of the band tab 12 in comparison to the edge sections 24. The thickening leads to an improved absorption of the loads perpendicular to the frame from the axle bolt and stabilizes the band in this area without weakening the bearing block 28.

So that the axle pin 15 or its bearing sleeve 22 can be used with comparatively large diameters, which are desirable in relation to the heavy-duty property of the band, the edges 13 of the band tab 12 are modified such that the edge sections 24, which are in the region of the recess 21 facing away from the wall section 16, project beyond the adjacent edge edges. This configuration not only affects the stability of the band, but also its appearance positively. The wing-side hinge part appears slim.

The hinge plate 12, its clamping plate 17 and the axle pin 15 or its bearing sleeve 22 are covered by a cover cap 20. In Figure 4, the cap 20 is shown in perspective in the upper part. The Fig.la, lb show a sectional view in the installed state, in which the cover cap 20 is installed with its edges between the edges 13 of the band tab 12, so that the outer surfaces 34 of the cap 20 are aligned with the edges of the edges 13. 4 shows below a special configuration of the edges 13 in that they have steps 33 which are so deep that they correspond to the thickness of the cap wall. The deposits form, as can be seen from the perspective representation, additional vertical supports of the cap 20, so that this helps stabilize the band in the clasped area or in its area Position is stabilized in order to be able to resist violent removal as much as possible.

The cover cap 20, which engages with its edges 20 '' 'in the above-described steps 33, is designed differently at its ends 20', 20 ''. The end 20 '' is provided on the bearing pin side with bends 25, 29 of different design in Fig.la, lb. However, both bends have support ribs 51 which rest on the bearing sleeve 22 and support the cover cap 20 in the longitudinal direction. According to Fig.la the bend 29 is provided with a retaining tab 30 which projects from the bend 29 in the direction of the other end 20 'and engages behind the wall portion 16 of the hinge tab 12 and clasps together with the cover cap 20. The retaining tab 30 is adapted to the outer peripheral surface of the wall section 16.

The above-mentioned clasping is not present in the design of the cover cap 20 according to Fig.lb. Here, the bend 25 engages with an edge 25 'in a recess 26 of the bearing block 28. The recess 26 is designed such that when the wing is pivoted it does not form an obstacle to the required pivoting of the edge 25 of the cover cap 20. When the window sash is closed, the edge 25 ′ seals the bearing pin area to the outside and prevents an intervention preventing the bearing pin from being broken open by force. In both cases of Fig.la, lb, the cap is formed in the area of its bend 25,29 such that it can correspond to the changes in distance caused by the adjustments of the bearing sleeve 22 without loosening the cap 20 in this area is coming.

The other end 20 'of the cap 20 is U-shaped. A leg 31, which engages behind the hinge flap 12, sits on a bend forming the U-base 52 as a further bend. According to the Fig.la, lb there is a hole in the U-bottom 52, which is closed by a plug 53. After this plug 53 has been removed, the head 43 'of the adjusting screw 43 is accessible and can be take the cover cap 22 are rotated by engagement of an insert key in the inner polygonal recess, not shown.

The leg 31 engaging behind the hinge flap 12 is provided with a locking rib which engages in a correspondingly positioned notch not shown in the bottom of the hinge flap and for this purpose provides an additional anchoring of the cover cap 20.

In Fig.5, the reference numerals designate the same components as in Fig.la, Ib. In this regard, a further description of FIG. 5 is avoided and reference is made to the previously described representations. Of greater importance, however, is the formation of the band in the area of the mounting of the bearing pin 15 by the second bearing part with its band tab 12. Instead of the band tab 12 described above, a bearing eye 54 is provided on the edge of the bearing block, with a connection point 55 between the Band lapping 12 and the bearing eye 54 is an integral connection. The bearing eye 54 completely surrounds the bearing pin 15 or the bearing sleeve 22 surrounding the latter. At its ends perpendicular to the plane of the illustration, the bearing eye 54 is in one piece with edge sections 23, 24, so that an overall excellent stability is obtained even when the bearing eye 24 is formed as a picture.

The stability of the bearing of the bearing pin 15 is specified in that the bearing eye 54 is made thicker on the bearing block side compared to the wall thickness of the bearing eye 54 facing away from the bearing block.

The configuration of the cover cap 20 can be regarded as a further stabilization measure. This is provided in the region of its bulge 56, with which it adapts to the projecting edge profile of the projecting edge sections 24, with an angled portion 29 which is essentially perpendicular to the plane of the frame. A retaining tab 30 engages behind the bearing eye 54 and clasps it in a form-fitting manner, so that the cover cap 20 is clamped in place. The holding tab 30 lies between frame-side edge sections 23

Edges 13 of the band tab 12. For the clasping, reference is made to the description of the Fig.la. An improvement in the clamping effect is given in that the bearing eye 54 is provided with a contact surface 57 for the bulge 56 of the cover cap 20. As a result of the planar contact, the cover cap 20 is supported better against twisting.
