Abstract

The substructure has a carrier plate for a flap of the hinge strip, and two or more bearing blocks, fixable to the case, for axial and radial mounting of set screws entering threaded holes in the plate, in provision for adjustably fastening a hinge strip to a door or window case. Each screw (22) has a right-hand (23) and a left-hand (21) threaded section. One is allotted a correspondingly shaped threaded hole (24) in the carrier plate (25), and the other a correspondingly shaped threaded hole (20) in one of the bearing blocks (18). Threads on the two screw sections may be of different pitch. With rebated or non-rebated doors or windows, this combines adequate setting range in the axial direction with compact height and play-free mounting of the set screws.

Description

Device for adjustable fastening of a door or

Window strip on a frame The invention relates to a device the type defined in the preamble of claim 1.

Known substructures of such devices (DE-OS 23 39 623) have a carrier plate, at one end of which the associated hinge tab of the The door or window hinge is screwed tight and the other end is rigid with the frame is welded. The carrier plate also has one between its two ends arranged bending zone and can consequently by means of at least one adjusting screw, which is supported with one end on the frame, in a perpendicular to the frame longitudinal axis Direction can be adjusted.

Because of the one-sided welding of the carrier plate, however, is here no exact axial displacement, but only a pivoting around the weld seam possible.

The same applies to substructures of similar construction which the adjusting screws are welded to the frame in an axially immovable manner Bearing blocks are out and therefore a load-bearing part together with the weld seam for the carrier plate or the door or the window.

In other known devices of the type mentioned above on the other hand, an exact parallel displacement of the carrier plate is made possible in that the carrier plate is only suspended by means of the adjusting screws, which cannot be moved axially and are rotatably mounted in bearing blocks welded to the frame. It is the arrangement made so that the heads of the adjusting screws on load-bearing parts the bearing blocks are supported, while the shafts of the adjusting screws in the Bearing blocks formed slot openings protrude. With such storage the adjusting screws, a good axial and radial mounting of the same is practical not possible. For axial fixing, the screw head must namely firmly between the Bearing blocks and the frame to be clamped, what at. not careful welding of the bearing blocks to the frame leads to a relatively large axial play and even with more careful Welding is problematic for reasons of tolerance and also because the Screw heads on the relatively weak and therefore not sufficiently resilient Must support the frame wall. With regard to the radial bearing is the one described Device therefore not sufficiently free of play because the screw heads with certain Minimum tolerances can be formed relative to the load-bearing parts of the bearing blocks must and because the entire weight of the door or window each on the lower Shifted screw head and this is therefore excessively stressed. It is therefore intended equip the bearing blocks with additional load-bearing parts that are attached to the carrier plate and other parts provided support elements cooperate, what a light Adjustability of the device runs counter to.

Another problem with the use of the devices mentioned at the beginning is that this applies equally to rebated and unrebated doors and windows should be suitable, which on the one hand the largest possible adjustment of at least about seven millimeters and, on the other hand, the flatest possible construction of the entire device of about twenty-three millimeters or less.

The invention is therefore based on the object of a rebated and unrebated doors or windows suitable device of the initially designated Generate to create that despite sufficient adjustment in the purely axial direction and flat design enables backlash-free storage of the adjustment screws.

To solve this problem are the characterizing features of the claim 1 provided.

The invention differs from the devices mentioned at the beginning essentially in that the adjusting screws both in threaded holes in the support plate as well as in threaded bores of the bearing blocks and thus axially displaceable are. This makes the weight of the doors or windows even and free of play relocated to all existing adjustment screws and a smooth adjustment option created. It is also advantageous that due to the use of adjusting screws with a right-hand thread and a left-hand thread section at least a doubling of the adjustment path for the carrier plate, based on the axial displacement of the adjusting screws in the bearing blocks is achieved, so that relatively large adjustment paths can be achieved with just a few turns of the screw can. In addition, only a relatively small part of the small amount is available Space is required for the safe storage of the adjusting screws in the bearing blocks and therefore a relatively large part of this space for the adjustment of the carrier plate made available.

Further advantageous features of the invention emerge from the subclaims.

The invention is described below in connection with the accompanying Drawing explained in more detail using an exemplary embodiment. They show: FIG. 1 a Cross section through a known device for unrebated doors; Fig. 2 is a cross section by a known device for folded doors; Fig. 3 is a longitudinal section through a device according to the invention in its rear end position; Fig. 4 is a plan view to the device according to FIG. 3; 5 shows a detail of the direction according to FIG. 3 in its front end position; Fig. 6 is a longitudinal section through a Adjusting screw of the device according to FIG. 3 in an enlarged view; Fig. 7 to 9 sections through further embodiments of the invention.

1 shows a door hinge 1 for an unrebated door 2. The door hinge 1 contains a hinge flap 3 fastened to the door 2 and one to a frame 4 attached tape flap 5. The fastening device for the tape flap 5 contains a substructure 6 with a support plate 9, a pressure plate 8 and a Number of fastening screws 9 9 which through openings in the frame 4 through can be introduced and operated and the pressure plate 8 and the carrier plate 7 with the intermediate clamping of the hinge flap 5 clamped NEN. To protect the substructure 6 against the masonry a protective box 10 is provided that the substructure 6 encloses and is attached to the frame 4.

2 shows a door hinge 11 for a rebated door 12, which has a tape tab 13 attached to the door 12 and a tape tab 14 which with one of FIG. 1 corresponding and therefore provided with the same reference number Substructure 6 is attached to the frame 4.

The distance usually required between the facing Surfaces of the frame 4 and the hinge tabs 5 or

14 is seven millimeters for unrebated doors and for rebated doors Doors, on the other hand, ten millimeters. When using the same substructure 6 this must therefore at least one adjustment path of the hinge tabs 5 and 14 in the axial direction of the fastening screws 9 by three millimeters. enable. In addition, the hinge should be adjusted 5 or 14 in the axial direction of the fastening screws 9, starting from a central position, of two millimeters on both sides to be possible when assembling the The door or window make the necessary adjustments make to can. The entire adjustment path for the hinge tabs 5 and 14 should therefore at least be about seven millimeters. To carry out this movement is available at the A measured in the axial direction of the fastening screws 9 under the usual installation conditions Space of about twenty-three millimeters is available within which the entire Substructure must be accommodated.

For this purpose, the invention proposes that in particular from FIG. 3 and 5 visible substructure 16 in front. This substructure 16 contains at least two substantially identical bearing blocks 18, of which below only the upper bearing block in FIG. 3 is shown and explained in detail. The bearing block 18 is attached to a frame 19, preferably welded to this, and has a threaded bore 20 with an internal thread into which a first section 21 of an adjusting screw 22 arranged perpendicular to the longitudinal axis of the frame (cf. also Fig. 6) is screwed, which has an external thread corresponding to the internal thread 20 having. A second section 23 of the adjusting screw on the right in FIG. 3 22 also has an external thread and is in a with a corresponding Internally threaded threaded bore 24 of a carrier plate 25 is screwed. The adjusting screw 22 is thus axially displaceable both in the bearing block 18 and in the carrier plate 25 stored.

The two sections 21 and 23 of the adjusting screw 22 are threaded provided with different directions of rotation, i.e. one of the two sections 21, 23 has a right-hand thread, while the other section has a left-hand thread owns. When turning the adjusting screw 22 in one direction or the other therefore places the carrier plate 25, measured in the axial direction of the adjusting screw 22, a way back that is twice as large as the axial displacement of the adjusting screw 22 is in the bearing block 18, provided the pitches of the two threads are the same.

However, the two sections 21 and 23 preferably have threads with different pitches. The thread with the smaller pitch is used P1 to section 21 and the thread with the larger pitch P2 to section 23 assigned, and corresponds, for example, to Pl one millimeter, P2 on the other hand two millimeters, then the carrier plate 25 with one rotation of the adjusting screw 22 by one Shifted distance of three millimeters, while at the same time the adjusting screw 22 covers a distance of only one millimeter in the bearing block 18.

For structural reasons, the thread has a smaller pitch expediently designed both as a left-hand thread and as a fine thread, while the other thread is designed as a right-hand thread and as a normal or regular thread is.

In a practical embodiment the thread of the section is 21 an M14 x 1 - left-hand thread and the thread of section 2 an M14 - right-hand thread, which usually has a pitch of two millimeters. To move the Carrier plate 25 to the required seven millimeters are therefore 2.33 revolutions the adjusting screw 22 is required, which is an axial displacement of the adjusting screw 22 makes it necessary in the bearing block by 2.33 millimeters. It is useful to have a slightly larger displacement of the adjusting screws provided, as a clear assignment the beginning of the thread is not possible.

The particular advantage of the measure described is that the thread of the section 21 practically during the entire displacement of the carrier plate 25 can remain fully engaged with the internal thread 20 of the bearing block 18, even if this, measured in the axial direction of the adjusting screw 22, is relatively proportionate for reasons of space must be measured briefly. This not only ensures that the adjusting screw regardless of the respective position of the carrier plate 25 radially and axially largely is stored without play in the bearing block IS, but also that there is also a high level of stability with regard to the fastening of the door or window, because the door or distribute the weight of the window evenly over all the adjustment screws can. Apart from this, the production of the bearing blocks 18 prepares manufacturing technology no big problems.

The bearing blocks 18 also have at least one each for the threaded hole 20 parallel bore 26, which is at a corresponding distance from the threaded hole 24 arranged and alignable to this parallel bore 27 in the carrier plate 25 and how this is used to receive a grooved or dowel pin 28.

The mounting of the support plate 25 takes place in such a way that the adjusting screws 22 are initially screwed with their section 23 into the threaded bores 24 until they assume the position shown in FIG. Then the Bearing blocks 18 screwed like a nut onto the sections 21 of the adjusting screws 22, until they assume the desired position within the threaded bores 20.

Then the bearing blocks are rotated until the holes 26 and 27 are aligned, and then the pins 28 are driven in, whereby the carrier plate 25 is non-rotatably fixed to the bearing blocks. The bearing blocks can now be welded to the desired location of the frame 19 before the associated hinge tabs attached to the carrier plate 25 in any manner will.

For this purpose, a pressure plate 29 is advantageously provided which has a plurality of holes 30, which on at corresponding intervals in the Support plate 25 provided threaded holes 31, on at appropriate intervals openings 33 aligned in the flap 32 to be fastened and on in corresponding ones Openings 34 formed at intervals in the frame 19 can be aligned. Before welding the Bearing blocks 18 on the frame 19 is the pressure plate 29 by means of the holes 30 inserted through and screwed into the threaded holes 31 fastening screws 35 attached to the carrier plate 25. This is usually done between the two Plates 25 and 29 clamped a disposable filling piece, which is to be assembled later Slap tape 32 simulated.

The door hinge is installed after the bearing blocks have been welded on 18 to the frame and after its installation. For this purpose, the fastening screws 35 completely unscrewed through the openings 34, whereby the pressure plate 29 is free comes, but is still held by the pins 28. After removing the disposable filling piece the hinge flap 32 is inserted, and then the fastening screws 35 screwed in again.

The required dimension between the inside of the frame and the one opposite it The side of the hinge flap 32 can now be produced by turning the adjusting screws 25 be by this by located in the frame 19 and on the heads 36 of the adjusting screws 22 aligned openings 37 are actuated therethrough. The achievable limit positions can be seen from Fig. 3 and 5 respectively. Parallel to the longitudinal axis of the frame, i.e. in Fig. 3 and 4 in the vertical direction, as well as in the one in Fig. 3 perpendicular to the plane of the drawing In the direction 1 running horizontally in FIG adjust that the openings 33 have a larger cross-section than the shafts of the Fixing screws 35 received.

In order to safely avoid that the adjusting screws 22 with frequent Loosen actuation of the door or the window, however, when using a fine thread for one of the sections 21 or 23 due to the natural self-locking hardly to is feared, additional anti-rotation devices can be assigned to the adjusting screws be. These anti-rotation devices can according to FIG. 5 made of plastic screws 38 exist, which run in perpendicular to the adjusting screws 22 and in the bearing block 18 formed bores are screwed in and each have a compressible end piece 39, that when tightening the plastic screws 3R against the thread of the sections 21 and thereby fixes the angular position of the adjusting screws 22. Alternatively the plastic screw can also be converted into a corresponding one formed in the carrier plate 25 Be screwed in the hole.

The plastic screws 38 should be made of a high temperature resistant material, e.g. a polyimide or a polyphenyl sulfide, because the frame is stove enamelled after the substructure has been welded on.

According to a further alternative it can be provided that the carrier plate 25 to bend slightly in the area of the threaded bores 24, thereby creating a Obtain self-locking for the adjusting screws 22.

To achieve that the bearing blocks 18 after reaching the desired The position of the adjusting screws 22 is not yet a maximum of almost a complete turn be rotated further measure, can in the bearing blocks 18 several, preferably Bores 26 arranged at equal angular intervals around the threaded bore 20 be arranged. When using two bores, maximum further turning is then required from 1800, when using four bores 26 a maximum further turning of only 900 required.

Instead of the grooved or dowel pin 28 shown above in FIG can be provided in accordance with the lower part of FIG. 3, a dowel pin 40, the at least in its located between the carrier plate 25 and the bearing block 18 Section 41 has an enlarged cross section. This cross-sectional enlargement is so large that the pressure plate 29 is practical in the position shown in FIG sits on the dowel pin 40 and therefore not when loosening the fastening screws 35 slide down in the gap between the carrier plate 25 and the inside of the frame can.

When the adjusting screws 22 are in their end position shown in FIG occupy, the heads of the fastening screws 35 have a relatively large Distance from the inside of the frame, if it is to be avoided that it is in the other End position (Fig. 5) protrude too far from the visible frame surface. To the Covering the unattractive-looking openings 34, cover caps 42 are therefore provided, cie are placed on the openings 34 from the outside and inwardly protruding projections 43 have undercuts 44 which, when the cover caps 42 are put on, behind snap into place on the inner edge of the frame and clamp the cover caps 42 in place.

To adapt to different frame thicknesses, you can do this lengthways of the projections 43 several such undercuts 44 at suitable intervals be provided. Alternatively, it is possible to use washers for the fastening screws 35 45 to be assigned, which during the assembly of the hinge flap 32 between the pressure plate 29 and the heads of the fastening screws 35 are placed so that these heads after the assembly regardless of the position of the support plate 25, for example, always the assume the position shown in Fig. 3 relative to the inner side of the frame. Another Cap 47, each with one at the rear, can be used to cover the openings 34 and 37 Projection 48, which is in an axial bore of the fastening and adjusting screws 22,35 is pressed in and preferably made of plastic.

The substructure described can be used to protect against the masonry with a protective box 46 attached to the bearing blocks 18 or to the frame (Fig. 5) be surrounded.

The various holes and openings in the parts described are expediently arranged so that the hole pattern that has been used for a long time in the Frame is retained that the two openings 37 above and below Actuation of the adjusting screws 22 and the four openings in between 34 for actuating the fastening screws 35 includes. Also, the heads should the adjusting and fastening screws 22,35 be designed in such a way that these can be operated with the same key, e.g. with the usual Allen key can.

According to a preferred embodiment (FIG. 7), the bearing blocks are 49 designed as cylindrical disks, while the pressure plate 29 on both of them the ends adjacent to the bearing blocks 49 each have a segment of a circle, the associated one Has bearing block 49 partially encompassing recess 50. The cylindrical bearing blocks 49 are cheaper than those shown in FIG. 4 for manufacturing reasons cuboid bearing blocks 18 and allow a statically more favorable welded connection between the bearing blocks and the frame. The circular segment-shaped recesses 50 on the other hand, cause the pressure plate 29 with the fastening screws removed 35 is held in the horizontal direction and therefore when inserting the hinge flap 32 cannot slip backwards, which is the case with substructures without a protective box could happen.

The recesses 50 can be designed so that the pressure plate 29 rests in its area on the bearing blocks 28 and thus also a load-bearing Function.

When installing particularly heavy or heavily used doors at least one additional counter screw 51 (Fig. 8) can be provided, which after correct setting of the adjusting screws 22 through additional openings 52 and 53 of the frame 19 and the bearing block 18-through in a correspondingly provided Threaded hole of the support plate 25 is screwed in and this with the bearing blocks 18 braced.

Additional stabilization is also possible in that according to 9 at least one guide pin 54 is provided instead of the counter screw 51 is, which is mounted in a bore of the bearing block 18 and either with his head 55 is supported between the bearing block 18 and the frame 19 or by a The cross pin is secured on the bearing block 18. Each guide pin 54 has a corresponding one arranged bore of the carrier plate 25 assigned so that this on the Fürhungsbolzen 54 slides.

Another way to increase the stability of the device and to eliminate the bearing play that may

due to the sole use of the adjusting screws 22 for storage the door could arise is indicated in the lower part of FIG. The carrier plate 25 is at its lower end that receives the adjusting screw 22 after manufacture of the threaded hole 24 with a parallel to the broad side of the carrier plate Slit 56 is provided which extends approximately to the axis of the adjusting screw 22. This slot is slightly compressed before screwing in the adjusting screw 22, so that the subsequently screwed in adjusting screw 22 over its thread the original Plane parallelism of the two sections of the carrier plate formed by the slot 56 25 seeks to restore. This creates an elastic pretensioning of the plate sections against the adjusting screw 22, which eliminates the thread play and the adjusting screw 22 is secured against loosening. In a corresponding manner, the bearing block 18 have a slot 57.

According to Fig. 3, the slot 57 of the bearing block 18 is with a screw 58 combined, protrudes through the stain formed by the slot 57 and sections serves to adjust these two sections after adjusting the adjusting screw 22 to brace against each other. This can already be done during the factory assembly of the Substructure take place so that no additional opening in the frame 19 is required and the usual hole pattern is retained.

Corresponding anti-rotation locks for the adjusting screws 22 can finally also with the help of radially in the carrier plates 25 and / or bearing blocks 18 extending slots are brought about.

There is a particular advantage of the substructure according to the invention that the hole pattern usually provided in the frame, formed by the Openings 34 and 37, except when using the embodiment according to 8 need not be exited. This hole pattern and accordingly also the The space available to accommodate the substructure is provided by the special type of frame production, e.g. the punching tools used, given and can therefore not, which is for reasons of improved stability the substructure itself would be desirable to be abandoned. Despite this given restrictions, the construction according to the invention is extremely stable and shows no signs of fatigue even in long-term tests.
