Description

The The invention relates to a concealed hinge according to the preamble of the claim 1.

Verschwindscharniere are on the one hand in the frame, on the other hand in the frame of the adjacent Door or sash installed so that they open and Conclude of doors or enable windows, without the Individual parts of the hinge on the corresponding outer or viewing area the door or the window appear visually. Besides, is this type of concealed hinge ensures increased burglary protection, since the hinge is not when the window or door is closed accessible is.

From the DE 41 37 050 A1 a concealed hinge for a door is known in which both the frame and the door frame connected by the hinge elements to the frame are formed as a box profile. The known disappearing hinge has a hook-shaped hinge bracket, the foot of which is fastened to the door frame profile to be pivoted by means of a separate holding part to be positioned in the interior of the profile. On the holding part required for screwing the hinge bracket base, a pin is provided, which must be inserted from the interior of the door frame profile through the profile wall and inserted into a corresponding hole in the hinge bracket base in order to be able to fasten the retaining section. The other end of the hinge bracket ends in a holder in which the relevant end of the hinge bracket is pivotably mounted by means of a bearing pin. The holder is arranged within the frame profile, so that the axis of rotation of the hinge bracket extends within the frame profile and essentially parallel to the axis of the frame profile. The mounting and fastening of the bracket with the bearing pin for the hinge bracket is carried out from the side of the frame profile, which faces away from the door frame when the door is closed.

The one from the DE 41 37 050 A1 Known solution has the disadvantage that no adjustment is provided on the construction of the hinge elements, through which an adjustment of the door frame, and thus the door leaf can be carried out after installation in the frame. Such adjustment is necessary despite high accuracy in the manufacture of the individual parts of the door, in particular in the case of large doors with relatively heavy door leaves, in order to enable the door leaf to be fitted exactly into the frame profile running on three sides.

From the DE 296 02 084 U1 a vanishing hinge is known which comprises adjusting means which have parallel separating surfaces with mutually interlocking toothing and thus enable the sash to be adjusted relative to the frame.

The The disadvantage of this adjusting means is that the wing has to be adjusted Adjustment means released and must be tightened again after adjustment.

task The invention is therefore a hinge of the beginning mentioned type in such a way that a simple and precise Installation of the hinge afterwards exact adjustment relative to the frame is possible as well as a concealed hinge to indicate with adjusting means, which the disadvantages of the state of the Technology does not have.

This Task is at the disappearance hinge of the aforementioned Kind according to the invention solved, that second adjusting means for the relative height adjustment of the frame profile across from the frame profile between the pin tab and the hinge bracket in active engagement arrive and the second adjusting means contain a grub screw, which can be screwed to one of the pin tabs parallel to the bearing journal is stored and rests with one end against the hinge bracket.

The Advantages of the invention are in particular that when in use the disappearing hinges according to the invention on a door or window sash held in a frame that on the concealed hinge provided adjustment option considerably easier for the exact fitting of the swiveling wing can be and also with longer Use can be adjusted precisely. For this purpose, between the anchor body and the end of the hinge bracket remote from the rotary axis, through which the frame profile, and thus the door leaf, is adjustable relative to the frame is held.

All Adjusting means individually or together cause that between the frame profile of the wing and the frame profile often present elastic seals or sealing lips their intended effect, namely the Sealing the remaining gaps with the wing closed fulfill it effectively can.

The distance between the pin tabs is greater than the vertical height of the end of the hinge bracket remote from the axis of rotation and between the hinge bracket and the pin tabs act the second adjusting means, which enable the relative height adjustment of the frame profile relative to the frame profile and adjust the distance accordingly, for example between the upper pin tab and the hinge bracket. The second adjusting means is designed as a threaded pin, which is preferably screwed to the upper support tab - parallel to the bearing journal - and rests with its lower end against the hinge bracket and changes the vertical position of the pin tab relative to the hinge bracket when rotated.

The first actuating means are advantageously by a carriage realized the slidably mounted in the anchor body and is connected to the end of the hinge bracket remote from the rotary axis is. The anchor body is preferably formed as a hollow profile, the longitudinal axis parallel to the longitudinal axis of the bearing pin, that is to the axis of rotation of the hinge bracket. The Hollow profile has a rear wall, one the hinge bracket facing front wall and two parallel side walls. The sledge is in that Anchor body cavity between back wall and front wall slidably mounted and has a holding section, through an opening or recess protrudes in the front wall and with the remote axis End of the hinge bracket connected is. There are preferably two parallel adjusting screws in the slide screw-mounted in a threaded hole. The head of the set screws lies against the inner surface the front wall, the free end of the set screws against the rear wall of the anchoring body on. An access opening is provided in front of the head of the set screws, through which - by means of a suitable key - the set screw form - and force fit detected and can be adjusted. For example, if the slide is the set screws of the rear wall of the anchor body approximated so approaching itself in the same way the hinge bracket, and thus the through axis of rotation of the hinge, the anchoring body. The distance between the frame profile and the frame profile is reduced.

There usually at least two hinges for attaching a door or sash needed can be also an undesired inclination of the wing correct that the first adjustment means of the two hinges adjusted differently become.

The anchoring body preferably has an end piece at each of its two ends, the are preferably inserted in the end face of the hollow profile and - after Introduce of the slide and the set screws - also on the end faces of the hollow profile attached, for example welded. Through the hollow profile and the end pieces preferably threaded holes, which fastening screws record with which the anchoring body on the outside Wall of the frame profile or the frame profile can be attached.

According to one another preferred embodiment According to the invention, the carriage has two spaced, vertical aligned tabs that are inserted through a recess or opening the front wall of the anchor body protrude through the end of the hinge bracket remote from the rotary axis and e.g. by means of at least one vertical pin with the rotary axis remote End of the hinge bracket are connected.

Especially preferably the end of the hinge bracket remote from the axis of rotation points parallel for a trunnion through hole in which the third adjusting means are arranged, which is the setting of a horizontal offset enable between the frame profile and the frame profile - transversely to the sash plane, the wing's pressure to be able to adjust to frame-tight sealants. The third means contain a sleeve, the rotation-free in the through hole of the end of the hinge bracket remote from the rotary axis stores and has the vertical hole for the retaining pin. The third adjusting means also contain at least one adjusting screw, by means of the end of the hinge bracket remote from the axis of rotation - horizontally and transversely to the wing plane - against the sleeve is movable. For this purpose, the through hole of the hinge bracket in the direction of adjustment a larger extension than the sleeve, so that one Relative displacement of the end of the hinge bracket free of the rotary axis to the sleeve possible is. The set screw is preferably located in a threaded hole in the Sleeve and lies with both ends on the inner surface of the through hole and is from the outside via an access hole accessible from the top and adjustable.

additional Advantageous developments of the invention are due to the features of further subclaims characterized.

in the the following is an embodiment of the Invention explained with reference to the drawings. It shows:

1 a plan view of a concealed hinge, which is installed in a hollow frame profile and a hollow frame profile, in the closed position of the wing;

2 one of the 1 corresponding representation with the wing open;

3 a side view of a disappearance hinge;

4 an exploded view of the hinge according to 3 , partly in section;

5 a plan view of the hinge bracket;

6 a section through the representation of the 7 along the line VI-VI;

7 a section through the representation of the 6 along the line VII-VII; and

8th an individual representation of the second and third actuators.

The 1 to 4 show a concealed hinge in plan view or in side view.

The 1 to 4 show a concealed hinge when installed, seen from above ( 1 . 2 ), seen from the side ( 3 ) and in an exploded side view ( 4 ). 1 shows a top view in the closed position of the door or window sash, 2 shows the corresponding top view in the open position of the door or window wing.

The disappearing hinge according to the 1 to 4 has a bracket 4 that in a box profile of a frame, the so-called frame profile 3 is installed. The concealed hinge also has an anchoring body 40 on that in the frame profile 2 of a wing 2a , for example a door leaf or a window leaf, is installed. On the bracket 4 is a bearing journal 10 attached, which is within the frame profile 3 extends parallel to its longitudinal axis, and on which a hinge bracket 20 pivotable about an axis of rotation 12 that with the longitudinal axis of the trunnion 10 coincides, is stored. The end near the axis of rotation 22 of the hinge bracket 20 takes in a corresponding hole 26 the bearing journal 10 on, the end remote from the rotary axis 24 of the hinge bracket 20 is about first actuators 60 . 90 - And in the embodiment shown - also via second actuating means 80 . 67 as well as via third means 30 . 100 , in the anchor body 40 adjustable in all three directions of a Cartesian coordinate system. The frame profile 2 and the frame profile 3 , ie, the wing 2a and the frame 3a are interchangeable without restricting the function of the concealed hinge.

In the 3 and 4 are - in side view - together with the 5 to 8th the individual parts of the concealed hinge and its structure are recognizable. The in the 3 and 4 bracket shown 4 has a front panel 5 with an opening 8th and with one over and under the opening 8th perpendicular to the front panel 5 protruding tang 6 , Both pin lobes 6 carry aligned holes 9 , by a bearing journal at a specified distance from the front panel 10 runs and is secured there. Through the opening 8th the hook-shaped hinge bracket extends through it 20 which at its end close to the rotary axis 22 on the trunnion 10 is pivotally mounted, the pivoting movement about the pin axis or axis of rotation 12 takes place, which - in the installed state of the concealed hinge - runs parallel to the longitudinal axis of the frame profile. The pivoting movement of the hinge bracket 20 will when the wing closes 2a by a stop between the frame profile 3 and frame profile 2 or between frame 3a and wings 2a limited; the pivoting movement of the hinge bracket 20 is when you open the wing 2a through a stop 7 limited to the bracket 4 is formed, and against which the hinge bracket 20 - when opening the wing - strikes.

Like the one in particular 4 and 6 can be removed, the concealed hinge with an anchoring body 40 in the frame profile 2 used and on the frame profile 2 of the wing 2a attached.

The anchor body 40 is in the embodiment shown as a hollow profile 41 trained, the longitudinal axis 41a parallel to the longitudinal axis 12 of the trunnion 10 runs. The hollow profile 41 becomes from a back wall 42 , one the hinge bracket 20 adjacent front wall 44 and two parallel side walls 46 is formed and is the end of each end piece 50 closed, which - in the embodiment shown - fits into the ends of the hollow profile 41 inserted and fastened there. front wall 44 and end pieces 50 have aligned holes / threaded holes on which the anchoring body 40 on the frame profile 2 can be attached. Alternatively, it is also possible to use the hollow profile 41 shorten in the longitudinal direction and then the two end pieces 50 face of the hollow profile 41 put on and at the ends of the hollow profile 41 to fix.

In the area of the opening 45 the front wall 44 is in the hollow profile 41 a sleigh 60 slidably mounted, which has the shape of a rectangular full profile and between the two side walls 46 of the hollow profile 41 is led. The sled 60 extends in the longitudinal direction of the hollow profile 41 and reaches behind the front wall 44 on both sides at the edge of the opening 45 , The sled 60 owns between the back wall 42 and the front wall 44 a measure of the distance between the rear wall 42 and front wall 44 is reduced by a displacement x and thus a displacement of the carriage 60 between front wall 44 and back wall 42 allowed. The displacement of the sled 60 takes place in the x-direction in a plane that is partially or entirely on the wing 2a circumferential frame profile is defined and is also referred to as the sash level.

Parallel to the level of the frame profile 2 , ie there are two set screws in the x direction 90 in corresponding threaded holes in the slide 60 screw-mounted and their heads lie against the inner surface of the front wall 44 , with its other end against the inner surface of the rear wall 42 of the hollow profile 41 and are each through a comparatively small access opening 48 that in the front wall 44 is provided, accessible from the front by means of a socket wrench and adjustable. When turning the set screws 90 the sledge approaches 60 either the back wall 42 or the front wall 44 on.

On the sledge 60 is a holding section 64 arranged by the opening 45 in the front wall 44 of the hollow profile 41 protrudes through and two spaced pin tabs 66 bears their distance 110 from each other in the longitudinal direction of the hollow profile 41 , and thus in the Z direction by a predetermined amount ΔZ is greater than the corresponding height 111 of the hinge bracket 20 , The two pen tabs 66 have aligned holes parallel to the trunnion 10 in which pens 80 respectively. 86 can be used, which engage in corresponding blind holes or bores, which at the end remote from the axis of rotation 24 of the hinge bracket 20 - also parallel to the bearing journal 10 - Are provided so that in this way a connection between the holding portion 64 of the sled 60 and the end remote from the rotary axis 24 of the hinge bracket 20 will be produced.

The pin bearing in the upper pin tab 66 is as a threaded hole 67 trained and takes the grub screw 80 on the one with its lower end 82 for example in a blind hole 330 against the hinge bracket 20 comes to rest and the two pin tabs when adjusted 66 of the holding section 64 , and thus over the sled 60 the anchor body 40 and the frame profile attached to it 2 the door wing 2a upwards in the Z direction, i.e. parallel to the longitudinal axis of the bearing journal 10 raises or lowers in the opposite direction. The grub screw 80 and the threaded hole 67 in the upper pen tab 66 thus form the second adjusting means, which allow the sash to be adjusted in the Z direction, that is to say in the vertical direction, relative to the frame profile.

Like the one in particular 4 . 6 to 8th can be removed, the hinge bracket 20 at its end remote from the axis of rotation 24 parallel to the journal 10 , a through hole in the Z direction 27 with a cross-section deviating from the circular cross-section, which approximately has a square or rectangular shape with rounded corners. In this through hole 27 are the third means of control 30 . 100 arranged, which is an adjustment of a horizontal offset transversely to the wing plane, ie in the Y direction between the pin tabs 66 and the end remote from the rotary axis 24 of the hinge bracket 20 enable. The third means 30 . 100 contain a sleeve 30 , see. the 4 . 6 and 8th that consist of two annular parts 32 . 34 exists and via a screw connection 33 in the through hole 27 can be put together. Coming from above, the upper sleeve section has 32 a blind hole 33a , an internal thread towards the lower end 33 which is part of the screw connection 33 forms. The lower sleeve section 34 has a blind hole at its lower end 39 and a threaded hole above it 38 , which is transverse to the longitudinal axis of the sleeve section 34 runs and - in the through hole 27 used sleeve sections 32 . 34 - runs perpendicular to the wing plane, i.e. in the x direction. The sleeve 30 has a dimension in the Y direction which is smaller than the corresponding dimension of the through hole 27 of the hinge bracket 20 , whereas the sleeve dimension in the x direction, i.e. in the direction of the wing plane, corresponds to the corresponding dimension of the through hole 27 equivalent. The adjustment of the wing in the Y direction serves to set the contact pressure between the wing 2a and a frame-tight seal is available.

In the hole 38 the sleeve 30 there is a set screw 100 that together with the sleeve 30 the third actuators 30 . 100 forms and with their two ends 102 on the inner surface of the through hole 27 is applied. It is through a comparatively small access hole 29 in the hinge bracket 20 accessible from the top by means of a key and sends the hinge bracket when adjusted 20 relative to the sleeve 30 in the Y direction. In contrast is the sleeve 30 through the grub screw 80 and the holding pin 86 stable and non-rotating against the pin tabs 66 fixed. The holding pin 86 has, for example, a cross-section deviating from the circular shape and thereby ensures that the sleeve 30 rotation-free in the through hole 27 of the hinge bracket 20 and rotation-free in the corresponding cross-sectional bore 68 of the pen tab 66 is fixed.

In the area of the threaded hole 38 and the set screw stored here 100 is the lower sleeve section 34 with a drop 37 provided between the sleeve portion 34 and the threaded hole 38 Space for the head of the set screw 100 creates.
