Description

The invention relates to an adjusting device of a rotating band of doors or windows, comprising a hinge plate to be attached to an end wall of a frame spar, with an adjusting plate arranged between the end wall and the hinge plate, which has at least one adjusting bevel and thus the hinge flap at different settings of an adjusting device. acting on the adjusting plate, allowed to keep at different distances from the end wall.

An adjusting device with the aforementioned features is known from DE 197 39 930 A1 known. The adjusting part is an eccentric, which is rotationally adjustable with respect to the end wall and with an eccentric disc allows adjustment of the voltage applied to the end wall adjustment plate. In different position of the adjustment plate of the hinge flap enters positions with different distances from the end wall. The adjustability of the adjusting plate is made difficult by a large engagement of the eccentric disc in an adjustment slot of the adjusting plate. It is possible that the displacement plate arranged obliquely relative to the hinge plate and thus a reliable fit between the displacement and the hinge flap is affected. In particular, in this case, it may lead to a loosening of the connection between hinge tabs and the displacement, so to a relaxation of the seat of the hinge strap on the frame spar. In addition, the eccentric disc adjustments of the adjusting plate in all directions parallel to the end wall of the frame spar, so that not only the distance of the hinge strap can be influenced by the end wall, but at the same time the position of the hinge plate parallel to the end wall.

An adjusting device exhibiting rotary belt is also from document FR 2 755 462 known.

In contrast, the invention has the object to facilitate the adjustment process.

This object is solved by the features of the main claim 1.

It is important for the invention that the adjustment plate is exclusively vertically adjustable. Each adjustment of the adjustment plate thus leads to a single and thus unique repositioning of the adjustment and thus the hinge. Furthermore, it is achieved that the hinge plate is not directly involved in securing its support position perpendicular to the end wall. Rather, instead of the hinge strap, the adjusting plate is supported by adjusting bevels on adjusting bevels of a base plate which is immovable on the end wall. The support of the adjusting plate on the base plate can be achieved with the required accuracy and safety by appropriate detail training can be used. The adjusting plate is correspondingly closer to the base plate or further from this removably positions and acts on the hinge tabs accordingly.

To secure different positions of the adjusting plate with respect to the base plate, the adjusting device can be formed so that the Einstellschrägen the adjustment plate and the base plate are provided with horizontal, to be brought into mutual engagement locking ribs and / or locking grooves. The horizontal locking ribs and / or locking grooves prevent unwanted adjustments in the vertical direction. The adjustment bevels of the adjustment plate and the base plate accordingly can not slip off each other.

A particularly advantageous embodiment of an adjustment provided with adjusting adjustment is characterized in that the base plate has two spaced from each other vertical rows of provided with Einstellschrägen plate projections, and that the adjustment plate is provided with the plate projections corresponding arranged Einstellschrägen having recesses. Plate projections of the base plate engage in the recesses of the adjusting plate, so that a perpendicular to the end wall of the frame spar compact embodiment of the adjustment results.

The adjustment is suitably designed so that the adjustment cooperates with the base plate. Since the latter is immovably supported on the end wall, it forms a reference point from which different positions of the adjusting plate can be set with the aid of the adjusting device. In terms of a perpendicular to the end wall of the frame spar compact design of the adjusting device, this is designed so that the adjustment between the rows of plate projections and the recesses is arranged.

For a perpendicular to the end wall of a frame spar compact adjustment on the one hand and the largest possible adjustment range on the other hand, the adjustment can be designed so that the adjustment is cooperating with an adjusting adjusting screw. The adjusting screw can be made sufficiently long, it can be stored safely and without Verstellrisiko due to their length and their adjusting allows a secure coupling with the adjustment plate.

A constructive preferred adjustment is characterized in that the adjusting screw is fixed axially positively to the base plate with a screw head, and that the adjusting nut engages axially positively in the adjustment plate. The positive fixing of the screw head and the positive engagement of the adjusting nut allows a simple mating of the components involved transversely to the end wall. The adjusting device can be designed so that the hinge tab is held on the base plate parallel to the end wall of the frame spar immovable. Thus, the hinge flap is secured in all its vertical to the end wall possible positions against displacements in other directions, namely the end wall parallel.

In order to facilitate the application of the adjustment, this can be formed so that the hinge flap has a provided with a pointer observation window in front of the marked with adjustment plates.

The adjustment plate is to be positioned between a base plate and the hinge plate. To facilitate this positioning or to prevent unintentional adjustment of the adjusting plate, the adjusting device can be formed so that a spring-loaded nut is connected to the base plate, in which a screwed the band tab and the adjusting plate to the base plate-pushing retaining screw is. As a result, the hinge plate and the adjusting plate are again subjected to force with the retaining screw pressed against the base plate, so that in particular the adjustment plate can not slip.

A constructive solution of an adjustment is characterized in that a spring-loaded mother is arranged on the end wall side of the base plate within the frame spar. The mother does not contribute in the area between the adjusting plate and the base plate, but can be housed in the frame spar.

For the aforementioned space reasons, the adjustment of the other can be formed so that the base plate has a front wall side projecting retaining sleeve of a coil spring which is firmly connected to the mother.

The invention also relates to an adjusting device with an attached to an end wall of a frame spar of a door or a window hinge strap of a rotating band whose height position on the frame spar with a frame-parallel adjustment movements causing screw adjustment is adjustable, which is supported on the frame spar. Such adjustment is also from the DE 197 39 930 A1 known. It consists of a particular of the rotating hinge on the frame spar posted bearing block with the Schraubverstellorgan, by the rotation of the hinge strap can be adjusted by loosening screws vertically in both directions.

This known adjustment serves a height adjustment of the rotating belt. It increases its vertical length, since the Schraubverstellorgan is arranged below the band flap to be attached.

In order to make the adjustment compact and also in connection with the above-described adjustment perpendicular to the end wall of the frame spar secure against adjustment, the adjusting device is formed so that the Schraubverstellorgan is arranged in a recess of the hinge strap and engages a recess edge of the hinge.

Due to the arrangement of the Schraubverstellorgans in a recess of the hinge strap any supernatant of Schraubverstellorgans over an edge of the hinge plate can be avoided, so that there is a corresponding compactness of the rotating belt. Its height adjustment is ensured by the fact that the Schraubverstellorgan engages a recess edge of the hinge. Here is a secure support can be achieved.

In a suitable adjusting device is preferred that the Schraubverstellorgan is a threaded spindle piece. A threaded spindle piece is simple and inexpensive to manufacture. It contributes little in all transverse directions, so that it is to be arranged transversely to save space despite the required length.

The adjusting device may be formed so that a threaded spindle piece is arranged adjacent to both ends of a respective Ausnehmungskante the hinge plate. Both ends of the threaded spindle piece can be used to effect adjustments of the hinge flap. As a result, it is not necessary to excessively loosen fastening bolts of the hinge to achieve a downward vertical displacement of the hinge by gravity.

In order to attach the threaded spindle piece bezel side, the adjusting device can be formed so that a threaded spindle piece in one on Blendrahmenholm immovable angegeschlagenen spindle slide is held rotatably adjustable. All forces that occur during rotation of the threaded spindle piece are transmitted from the threaded spindle piece to the immovably struck spindle slide.

In terms of a compact design, it is advantageous to form the adjustment so that a spindle slide is arranged in a height adjustment correspondingly longer recesses of the hinge strap and, if necessary, a guide of the hinge strap is used. A guide of the hinge strap by means of the spindle slide is to be achieved in particular if this is matched to the recess width of the hinge strap and is dispensed with otherwise guiding the hinge strap.

Advantageously, an adjusting device, in which a spindle slide is arranged at the height of a axle bearing block of the rotating belt. This results in an advantageous stabilization of the rotating belt.

It is preferable to form an adjusting device so that the spindle slide is H-shaped and its crosspiece has a threaded bore for the arranged between the longitudinal webs threaded spindle piece. It results in a compact design in all directions of a height adjustment of the rotating belt serving components.

The spindle slide can be used to attach the hinge strap to the frame rail. For this purpose, the adjusting device is formed so that the spindle slide has a band tab in the region of the recess cross-clamping plate. The pressure plate can be bolted to the frame spar, for example, so that it presses the hinge plate firmly against the frame rail.

In order to relieve the fastening of the hinge strap serving screw means, the adjusting device can be formed so that the spindle slide has at least one engaging in the frame spar guide pin.

It may be necessary to fasten the rotating band particularly securely to the frame spar. This is especially the case with a highly loaded three-piece rotary belt. It may therefore be an adjustment of advantage that in a three-piece rotating belt at the level of an upper axle bearing block engaging in a guide recess of the hinge strap guide carriage is present. The guide carriage is used to stabilize the rotating band in the upper region of the three-piece rotating belt and at the same time is able to guide the hinge tab upon actuation of the adjusting device. At the same time, the guide carriage can be an attachment of the rotating belt or the hinge strap after a height adjustment.

In order to minimize the manufacturing cost of the rotating belt, it is advantageous to form the adjusting device so that the guide carriage is formed identical to the spindle slide.

The FIGS. 1 to 6 each show the same complete rotary belt 10, consisting essentially of a hinged to a wing hinge tabs 12 and a hinged to a frame hinge hinge 35. The hinge tabs 12,35 are connected in a manner not shown by means of a hinge pin with each other pivotally adjustable.

The Fig.1 shows sectional views of a frame member 32 of a sash and a frame spar 33 of a window frame, wherein the rotary belt 10 serves a pivotable articulation of the wing. The wing band 12 and the frame band 35 are shown only schematically to show how they are in the rebate between the wing and frame are arranged in principle. The hinge tab 12 is struck on an end wall of the frame member 32 and the hinge tab 35 is struck on an end wall 31 of the frame member 33. When the wing is pivoted to its closed position, an immediate vicinity of the tabs 12,35 results in a view corresponding Figure 16 ,

With respect to the design of the adjusting the formation of the frame members 32,33 is arbitrary. In Fig.1 thermally insulated frame beams have been shown, the outer and inner profile parts are connected to each other by heat-insulating connection profile parts together, with metal profile parts and an existing plastic profile part together form the frame walls 11 and 31 respectively.

The rotary belt 10 is formed so that with its help, an adjustment of the wing or the frame member 32 can be made vertically to the end wall 11, as well as parallel to the end wall 31. For these purposes, the hinge tabs are 12.35 in different ways at their End walls 11,31 attached. The manner of attachment is in each case matched to the design of the adjusting device, which serves in the hinge flap 12 an adjustment of the distance of this hinge strap 12 of the end wall 11, and which serves in the hinge tab 35 a vertical adjustment of this hinge strap 35 vertical to the plane.

The 2 to 7 show that the rotary belt 10 is a so-called three-piece rotary belt. It owns according to Figure 7 an upper bearing block 40 and a lower bearing block 39. Both bearing blocks 39,40 are integral with the hinge plate 35 which is to be attached to the frame spar 33. This particularly stable design of the hinge strap 35 serves to transmit large wing loads on the frame. The wing loads are transmitted from the hinge flap 12 on the hinge tab 35, wherein the hinge tab 12 with a bearing eye 12 'between two bearing eyes 39 'and 40' of the hinge flap 35 is arranged, compare for example Fig.2 , In this storage, the bearing axis not shown engages in bushings 39 '', 40 '' of the lower and upper bearing block 39,40 and passes through the bearing eye 12 'of the hinge 12. The lower bearing eye 39 is provided with a lower cap 39''' closed and the upper bearing eye 40 is closed with an upper cap 40 '''. It can be seen that the cross-section of the bearing bores 40 '''' and 39 '''' eccentrically with respect to a central axis 22 of the bearing eyes 39,40 is formed. Accordingly, eccentrically the bearing axis, not shown, held, with the result that the bearing eye 12 'of the hinge plate 12 is held correspondingly eccentric, which is evident from the representation of the hinge flap 12 in Figure 6 in the area of adjacent bearing bushes 39 '', 40 '' on the one hand and 58 on the other hand results. By rotation of the bearing bushes 39 '', 40 '', a corresponding adjustment of the bearing axis can be achieved in order to achieve, for example, a Andruckänderung between the sash and frame. Such a pressure change is due to the rotation of the eccentric bushings 39 '', 40 '' always connected to a displacement of the wing perpendicular to its end wall. If such a displacement is undesirable, it can be compensated by adjusting the spacing of the band tab 12 from the associated end wall 11.

In order to achieve an adjustment of the distance of the hinge strap 12 from the associated end wall 11, an adjusting device is provided, the total, in particular from the 8 to 11 and regarding their details from the 12 to 18 can be seen. The rotating belt 10 is formed as a so-called roll band, wherein the hinge tab 12 consists essentially of the bearing eye 12 'and an angular support plate acting thereon, which is angular in such a way that they according to Fig.1 encompassing the rollover shown of the frame member 32 can be arranged with a plate leg 43 parallel to the end wall 11.

The plate leg 43 of the hinge plate 12 abuts against an adjusting plate 30, which in turn can be supported on a base plate 17. The base plate 17 is firmly against the end wall 11, to which they according to 8 to 10 may be provided with engagement strips 44,45, which engage in not shown receiving grooves of the frame member 32 and the base plate 17 can save against tilting assets.

The base plate 17 carries a plurality of plate projections 20. The plate projections 20 are arranged one above the other in three vertical rows 19, wherein the rows 19 have a distance of 18 from each other. Each plate projection 20 has a Einstellschräge 16. All Einstellschrägen 16 are provided with each other parallel horizontal locking ribs and locking grooves. Figure 12 can be seen on an adjusting plate 13 locking ribs 46, which alternate with not designated locking grooves.

The Einstellschrägen 16 cooperate with Einstellschrägen 15 of the adjustment plate 13. Their Einstellschrägen 16 are formed in recesses 21 which are so large that the plate projections 20 can engage sufficiently deep, so that both Einstellschrägen 15,16 come to rest against each other. The locking ribs / locking grooves of all Einstellschrägen are the same size and arranged horizontally in the same way, so that their mutual engagement means that the displacement plate 13 and the base plate 17 with a support of both plates on their Einstellschrägen 15,16 can not slip off each other.

Between the base plate 17 and the adjusting plate 13, an adjusting device 14 is provided which consists essentially of an adjusting screw 24 and an adjusting nut 23. The adjusting nut 23 is on a thread 24 '' the screw shank screw axially adjustable. In order to effect a displacement of the adjusting plate 13 relative to the base plate 17 with the aid of this adjusting device 14, the adjusting screw 24 is assembled with its screw head 20 axially form-fitting manner with the base plate 17. The assembly takes place with Figure 10 In an upper transverse wall of the base plate 17, a through-opening 48 is provided for a rotary tool, for example, a hexagon wrench, in the off Figure 10 or 15 apparent Innensechskantaufnehmung the screw head 24 is able to engage, so that the screw 24 can be rotated about its longitudinal axis. It is according to Figure 15 mounted immovable transversely to its longitudinal axis between the base plate 17 and the adjusting plate 13. The adjusting screw 23, which is longitudinally adjustable on the screw 24, engages in an engagement slot 49 of the adjustment plate and can adjust it vertically upwards or downwards in accordance with its axially positive engagement. In this case, the distance of the adjusting plate 13 from the base plate 17 changes according to the inclination of the Einstellschrägen 15,16. Accordingly, the distance of the hinge tab 12 from the base plate 17 and of the end wall 11, since the hinge tab 12 rests with the plate leg 43 on the displacement plate 13 changes.

The plate leg 43 is according to Figure 10 in cross-section U-shaped, so that he clasps the cover plate 13 with retaining strips 50, which in particular from Figure 18 can be seen. The cover plate 13 is supported on the one hand directly to a retaining leg 51 and on the other hand via a retaining strip 50 of the plate leg 43 on a holding leg 52 of the cross-section of Figure 18 U-like base plate 17. The other is off Figure 8 can be seen that the plate leg 43 engages vertically form-fitting between horizontal walls 53 of the base plate 17. As a result, the plate leg 43 and thus the hinge flap 12 is neither vertical end wall parallel to adjust horizontally parallel to the end wall. To change is only the distance of the plate leg 43 and thus the hinge strap 12 of the end wall 11 of the frame member 32nd

In order to recognize the respective position of the cover plate 13 between the plate leg 43 and the base plate 17, the plate leg 43 is provided with an observation window 26 in which a pointer 25 is mounted. The pointer 25 is according to, for example Figure 6 arranged in front of markings 27. The markings 27 indicate whether the cover plate 13 is moved upwards or downwards. An adjustment down means smaller distance of the hinge strap 12 of the end wall 11, an upward adjustment means a greater distance of the hinge strap 12 of the end wall 11th

An attachment of the hinge flap 12 on the frame member 32 is carried out with fastening screws, not shown. These fastening screws penetrate through-holes 12 "of the plate leg 43, through-holes 13" of the cover plate and through-holes 17 "of the base plate. In this case, the through-holes 12 "of the cover plate oblong holes, so screwed fastening screws not hinder an adjustment of the adjustment plate 13 in the vertical direction. There are a total of four through-holes 12 '', 13 '' and 17 '' available. The arranged in these holes mounting screws are slightly loosened when the position of the adjustment plate 13 is to be changed. So that all three components 43,13,17 abut each other and an unwanted adjustment of the adjusting plate 13 is avoided, all three components are pressed against each other by spring force. For this purpose, a coil spring 34, which is installed in a retaining sleeve 30 of the base plate 17, see Figure 11 . 18 , The coil spring 34 protrudes from the retaining sleeve 30 and carries at its free end a nut 38, see for example Figure 10 . 18 , In the nut 38, a retaining screw 29 is screwed, with its head 29 ' can press on the plate leg 43, if it is screwed deep enough. The nut 28 is pulled in the direction of the base plate 17, wherein the spring force increases with increasing adjustment of the nut 28. With the respectively determined by the rotational position of the retaining screw 29 spring force of the plate leg 43, the adjustment plate 13 and the base plate 17 are pressed together. As a result, the secured with the locking ribs 46 and locking grooves mutual engagement of the Einstellschrägen 15,16 is preserved and an unintentional adjustment of the adjustment plate 37 can be excluded. The Figure 9 . 17 and 18 show the nut 28 adjusted in the direction of the base plate 17.

The nut 28, the spring 34 and the sleeve 30 are mounted on the end wall side of the base plate 17 and obviously protrude so far that they would hinder a flat contact of the base plate 17 on the end wall 11. As a result, to form the base plate 17 on the end wall 11 form a corresponding receiving bore through which said components are inserted and then located within a cavity of the frame spar 32, where sufficient space is available.

It is also necessary to form the rotary belt so that it can be adjusted in its height position. The height position of the rotating belt on the frame member spar 33 is carried out expediently with a Schraubverstellorgan. The Schraubverstellorgan acts on the hinged on the frame hinge hinge 35 of the rotating belt 10 a. especially the Fig. 2.3 and 6 . 7 let recognize the formation of the adjustment for influencing the height position of the rotating belt 10 on the frame.

The hinge tab 35 is provided at the height of the lower axle bearing block 39 with a recess 36 into which a spindle slide 38 engages. The spindle carriage 38 is substantially H-shaped, thus has two mutually parallel longitudinal webs 38 '', which are connected by a transverse web 38 'integrally with each other. Between the longitudinal webs 38, the Schraubverstellorgan is arranged in the form of a threaded spindle piece 37. The threaded spindle piece 37 is a cut-to-length part of a threaded rod and passes through a threaded bore provided in the transverse web 38 '. The length of the threaded spindle piece 37 is chosen so that the latter between Ausnehmungskanten 36 ', 36''of the recess 36 fits. As a result, the threaded spindle piece 37 can be supported with its upper end on the upper recess edge 36 'and with its lower end face on the lower recess edge 36''. The threaded spindle piece is provided with a non-illustrated recess, for example with a hexagonal recess and can be rotated by means of a tool which engages in this recess. The engagement can take place through a Durchgriffsausnehmung 54, which is formed in the hinge flap 35. Fig.2 shows such a Durchgriffsausnehmung at the upper end of the hinge plate 35, it being understood that at its lower end a corresponding Durchgriffsausnehmung is present.

A rotation of the threaded spindle piece 37 in the transverse web 38 'of the spindle slide 38 causes, since the spindle slide 38 is fixed to the frame, that the hinge tab 35 is pressed upwards or downwards, depending on the direction of rotation. According to the required adjustment, the recess 36 is longer than the longitudinal webs 38 '' are.

The spindle slide 38 must be fixed to the frame. For this purpose, it is provided with a pressure plate 57 which rests against the frame-worn outer wall of the hinge plate 35, see for example Fig.2 ,

The pressure plate 57 has screw holes 55, which also through the longitudinal webs 38 '' of the spindle carriage 37 therethrough walk. As a result, not shown fixing screws can be inserted through the screw holes 55 and press on the pressure plate 57, which in turn pushes the hinge plate 35 against the frame, namely against the end face 31, in which the fastening screws are screwed. In this case, the spindle slide 38 is not quite as thick as the hinge tab 35th

There are two diametrically opposite screw holes 55 on the spindle slide 38 in the longitudinal webs 38 '' available. The consequently free further ends of the longitudinal webs 38 '' are filled with guide pins 44 which project from the spindle slide 38 in the direction of the frame 33 and accordingly are able to intervene in engaging holes formed there. These guide bolts 44 relieve the screws engaging in the screw holes 35 and serve the exact fit of the spindle slide 38 on the frame 33rd

The spindle slide 38 may be formed so that it guides the hinge tab 35 laterally. For this purpose, however, the cover plate 43 can be used, which abuts against vertical side edges 56 of the hinge strap.

At the height of the upper axle bearing block 40, a guide recess 41 is formed in the hinge flap 35. In this guide recess 41 engages a guide carriage 42 a. This guide carriage is identical to the spindle slide 38. Also, the guide recess 41 corresponds to the recess 36 of the hinge plate 35 for the spindle slide 38. Regarding the features of the guide carriage 42 and its guide recess 41 is therefore taken to the description of the spindle slide 38 and its recess 36 reference.
