Description

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

Hinges are on the one hand in the frame, on the other hand in the frame of the adjacent door or window sash installed so that they can be opened and Allow doors and windows to be closed without the individual parts of the Hinge on the corresponding outer or visible surface of the door or Window appear optically. In addition, such disappearance hinges ensure increased protection against burglary, since the hinge at ge closed window or door is not accessible.

From DE 41 37 050 A1 a concealed hinge for a door is known from which both the frame and the hinge elements with the frame connected door frames are designed as a box profile. The well-known Ver shrink hinge has a hook-shaped hinge bracket, whose foot by means of a separate, to be positioned inside the profile Holding part is attached to the door frame profile to be pivoted. On the for Screwing the required hinge bracket foot is a pin  provided, which from the interior of the door frame profile through the Profilwan plugged in and inserted into a corresponding hole in the hinge bracket foot must be set in order to be able to fasten the holding part. The other end of the hinge bracket ends in a bracket in which this is concerned fende end of the hinge bracket pivotally mounted by means of a bearing pin is. The bracket is arranged within the frame profile, so that the Axis of rotation of the hinge bracket within the frame profile and essentially extends parallel to the axis of the frame profile. The installation and attachment of the Mounting with the bearing pin for the hinge bracket is from the side of the Frame profile, which faces away from the door frame when the door is closed.

The solution known from DE 41 37 050 A1 has the disadvantage that the Construction of the hinge elements no adjustment is provided by which an adjustment of the door frame, and thus the door leaf after installation can be made in the frame. Such adjustment is despite high Accuracy in the manufacture of the individual parts of the door, especially for large ones Doors with relatively heavy door leaves are required in order to fit the To enable door leaf in the three-sided frame profile.

The object of the invention is therefore, a concealed hinge called ten kind such that a simple and precise installation of the hinge with subsequent exact adjustment relative to the frame is possible.

This task is in the disappearing hinge of the type mentioned solved according to the invention by adjusting means which the frame profile or Connect the frame profile to the hinge bracket in an adjustable position.

The advantages of the invention are in particular that when using the concealed hinges according to the invention a door or held in a frame Window sash possible through an adjustment provided on the disappearing hinge speed for exact fitting of the swiveling wing can be made considerably easier can and can be precisely adjusted even with prolonged use. To this Purpose are between the anchoring body and the rotary axis distal end of the Hinge bracket adjusting means provided, through which the frame profile, and thus the door leaf is held adjustable relative to the frame.

According to a preferred embodiment of the invention there are first adjusting means provided that a substantially horizontal position adjustment of the wing frame  mens, and thus allow the entire wing in the wing plane, by the three-sided or four-sided sash frame is stretched. This first adjusting means have the advantageous effect that the wing horizontally so can be fitted between the two vertical frame sections that the vertical gaps between the casement and the frame are both essentially have the same width and also a constant width over their length have.

According to a further particularly preferred embodiment of the invention second adjusting means are provided which allow vertical adjustment of the wing enable relative to the frame or the frame profile. These second actuators thus allow the horizontal gaps between the casement and the frame to be considered Lich adjust their width so that the wing exactly - on all sides with the desired Distance - in which the frame profile comes to rest.

According to a further preferred embodiment of the invention, there are third Adjustment means are provided, which an adjustment of a horizontal offset of the Sash or the sash profile opposite the plane of the frame profile enable by the partially or completely surrounding frame profile is defined. These third actuators make it possible to insert the wing plan into the insert the adjacent plane defined by the frame profile so that the sash in its closed position with the adjacent building level closes.

In addition, all adjusting means individually or together that the 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 when the sash is closed is also special can meet effectively.

The first actuating means are implemented by a sled, which is in the anchoring Rungs body is slidably mounted and with the end remote from the axis of rotation Hinge bracket is connected. The anchoring body is preferably a hollow profile formed, the longitudinal axis parallel to the longitudinal axis of the journal, that is The axis of rotation of the hinge bracket runs. The hollow profile has a rear wall, one the front wall facing the hinge bracket and two parallel side walls. The Sled is in the cavity of the anchoring body between the rear wall and Front wall slidably mounted and has a holding section through a  Opening or recess in the front wall protrudes and with the rotary axis far end of the hinge bracket is connected. In the sled are preferred two parallel set screws screw-mounted in a threaded hole. The The head of the set screws lies against the inner surface of the front wall, the free end the set screws against the back wall of the anchor body. Before the An access opening is provided at the head of the adjusting screws, through which - using a suitable key - the set screw is positive and non-positive can be detected and adjusted. For example, using the set screws the rear wall of the anchoring body approximates, then approaches in the same Way of the hinge bracket, and thus the one defined by the bearing journal Axis of rotation of the hinge to the anchor body. The distance between Frame profile and frame profile is reduced.

As a rule, at least two hinges for attaching a door or Window sash are required, can also be an undesirable inclination Correct the wing by moving the first adjusting means of the two hinges can be adjusted differently.

The anchoring body preferably has at each of its two ends an end piece, which are preferably inserted into the end face of the hollow profile and - after the insertion of the slide and the set screws - also on the front of the Hollow profile attached, for example, can be welded. By the Hollow profile and the end pieces preferably run threaded holes, which Pick up fastening screws with which the anchoring body on the external wall of the frame profile or the frame profile can be attached can.

According to a further preferred embodiment of the invention, the Slide two spaced, vertically aligned pin tabs that are separated by an off Take or opening in the front wall of the anchor body through protrude the end of the hinge bracket remote from the axis of rotation and z. B. by means of at least ver a vertical pin with the end of the hinge bracket remote from the rotary axis are bound.

The distance between the pin tabs is greater than the vertical height of the turn far end of the hinge bracket and between the hinge bracket and the Pin lobes preferably act on the second adjusting means, which affect the relative heights enable position of the frame profile relative to the frame profile and the distance  for example, between the upper pin tab and the hinge bracket adjust speaking. The second adjusting means is preferably designed as a threaded pin det, which can be screwed to the upper support tab - parallel to the bearing journal is stored and rests with its lower end against the hinge bracket and at one rotation the vertical position of the pin tab relative to the hinge temple changed.

The end of the hinge bracket remote from the rotary axis particularly preferably points parallel for the journal on a through hole in which the third adjusting means are ordered, which is the setting of a horizontal offset between the Frame profile and the frame profile - transversely to the sash level - allow to to be able to adjust the system pressure of the sash on frame-tight sealants. The third adjusting means contain a sleeve which is in the through hole of the rotary axis distal end of the hinge bracket and the vertical hole for the Has retaining pin. The third adjusting means also contain at least one Set screw, by means of which the end of the hinge bracket remote from the axis of rotation horizontal and transverse to the wing plane - can be moved against the sleeve. To this end the through hole of the hinge bracket has one in the direction of adjustment larger extension than the sleeve, so that a relative displacement of the rotary axis-free end of the hinge bracket relative to the sleeve is possible. The adjusting screw be sits preferably in a threaded bore of the sleeve and lies with both of them Ends on the inner surface of the through hole and is from the outside via a Access hole accessible and adjustable from the top.

Figs. 1 to 4 show a Concealed in plan view and in side view.

Figs. 1 to 4 show a Concealed in the installed state, as seen from above (Fig. 1, Fig. 2), seen from the side (Fig. 3) and in a lateral exploded view (Fig. 4). Fig. 1 shows a top view in the closed position of the door or window sash, Fig. 2 shows the corresponding top view in the open position of the door or window sash.

The disappearing hinge according to FIGS. 1 to 4 has a holder 4 which is installed in a box profile of a frame, the so-called frame profile 3 . The concealed hinge also has an anchoring body 40 , which is installed in the frame profile 2 of a wing 2 a, such as a door wing or a window wing. On the bracket 4 , a journal 10 is fixed, which extends within the frame profile 3 parallel to its longitudinal axis, and on which a hinge bracket 20 is pivotally mounted about an axis of rotation 12 which coincides with the longitudinal axis of the journal 10 . The end 22 of the hinge bracket 20 near the axis of rotation receives the bearing pin 10 in a corresponding bore 23 , the end 24 of the hinge bracket 20 remote from the axis of rotation is via first adjusting means 60 , 90 - and in the embodiment shown - also via second adjusting means 80 , 67 and via third adjusting means 30 , 100 , in the anchoring body 40 is adjustably supported in all three directions of a Cartesian coordinate system. The frame profile 2 and the frame profile 3 , ie the wing 2 a and the frame 3 a are interchangeable without restricting the function of the concealed hinge.

In Figs. 3 and 4 are - in side view - together with Figures 5 to 8, the individual parts of the Verschwindscharniers and its structure identified.. The holder 4 shown in FIGS. 3 and 4 has a front plate 5 with an opening 8 and with one above and below the opening 8 projecting at right angles to the front panel 5 Zapf cloth. 6 Both pin lugs 6 have aligned bores 9 through which a bearing pin 10 runs at a predetermined distance from the front plate and is secured there. The hook-shaped hinge bracket 20 protrudes through the opening 8 and is pivotably mounted on the bearing pin 10 at its end 22 near the axis of rotation, the pivoting movement taking place about the pin axis or axis of rotation 12 which, in the installed state of the disappearing hinge, runs parallel to the longitudinal axis of the frame profile . The pivoting movement of the hinge bracket 20 is limited when closing the wing 2 a by a stop between the frame profile 3 and frame profile 2 or between frame 3 a and wing 2 a; the pivoting movement of the hinge bracket 20 is limited when opening the wing 2 a by a stop 7 which is integrally formed on the bracket 4 , and against which the hinge bracket 20 - when opening the wing - strikes.

As can be seen in particular from FIGS. 4 and 6, the disappearing hinge is inserted with an anchoring body 40 into the frame profile 2 and fastened to the frame profile 2 of the wing 2 a.

The anchoring body 40 is formed in the illustrated embodiment as a hollow profile 41 , the longitudinal axis 41 a parallel to the longitudinal axis 12 of the bearing pin 10 . The hollow profile is formed on a rear wall 42 , a front bracket 44 adjacent to the coulter nierbügel 20 and two parallel side walls 46 and is closed at the end by an end piece 50 , which - in the embodiment shown - is inserted into the ends of the hollow profile 41 and fastened there is. Front wall 44 and end pieces 50 have aligned bores / threaded bores to which the anchoring body 40 can be attached to the frame profile 2 . Alternatively, it is also possible to shorten the hollow profile 41 in the longitudinal direction and then to place the two end pieces 50 on the end face on the hollow profile and to fasten them to the ends of the hollow profile 41 .

In the area of the opening 45 of the front wall 44 , a slide 60 is slidably mounted in the hollow profile 41 , which has the shape of a rectangular solid profile and is guided between the two side walls 46 of the hollow profile 41 . The carriage 60 extends in the longitudinal direction of the hollow profile and engages behind the front wall 44 on both sides at the edge of the opening 45 . The carriage 60 has a dimension between the rear wall 42 and the front wall 44 which is reduced by a displacement x compared to the distance between the rear wall 42 and the front wall 44 and thus permits a displacement of the carriage 60 between the front wall 44 and the rear wall 42 . The carriage 60 is displaced in the x-direction in a plane which is defined by the frame profile which runs partially or completely on the wing 2 a and is also referred to as the wing plane.

Parallel to the plane of the frame profile, ie in the x-direction, two adjusting screws ben 90 are screw-mounted in corresponding threaded bores in the slide 60 and lie with their heads against the inner surface of the front wall 44 and with their other end against the inner surface of the rear wall 42 of the hollow profile 41 and are accessible and adjustable from the front by means of a socket wrench each through a comparatively small access opening 48 which is provided in the front wall 44 . When the set screws 90 are turned, the carriage 60 approaches either the rear wall 42 or the front wall 44 .

Arranged on the carriage 60 is a holding section 64 which projects through the opening 45 in the front wall 44 of the hollow profile 41 and carries two spaced pin tabs 66 , the spacing a of which from one another 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 b of the hinge bracket 20 . The two pin tabs 66 have aligned holes parallel to the bearing pin 10 , into which pins 80 and 86 can be inserted, which engage in corresponding blind holes or holes which are provided on the end 24 of the hinge bracket 20 remote from the axis of rotation - also parallel to the bearing pin 10 - so that in this way a connection between the holding portion 64 of the carriage 60 and the end 24 of the hinge bracket 20 remote from the axis of rotation is produced.

The pin bearing in the upper pin tab 66 is designed as a threaded bore 67 and receives the threaded pin 80 , which comes into contact with its lower end 82, for example in a blind hole against the hinge bracket, and when the two pin tabs 66 of the holding section 64 are adjusted, and thus over the slide 60 raises the anchoring body 40 and the frame profile 2 attached to it / the door leaf 2 a upwards in the Z direction, that is to say parallel to the longitudinal axis of the bearing pin 10 or lowers it in the opposite direction. The grub screw 80 and the threaded hole 67 in the upper pin tab 66 thus form the second adjusting means, which allow an adjustment of the wing in the Z direction, that is, in the vertical direction relative to the frame profile.

As shown particularly in FIGS. 4, 6 to 8 is removed, the hinge bracket 20 has at its drehachsfernen end 24 parallel to the bearing journal 10, ie in the Z direction, a through hole 27 with a deviating from the circular cross-section cross-section which is approximately a square or rectangular shape with has rounded corners. In this through hole 27 , the third adjusting means 30 , 100 are net angeord, which allow adjustment of a horizontal offset transversely to the wing plane, ie in the Y direction between the pin tab 66 and the end 24 of the hinge bracket 20 remote from the axis of rotation. The third adjusting means 30 , 100 contain a sleeve 30 , cf. , there is Fig. 4, 6 and 8, the annular of two parts 32 and 34 may be assembled via a screw 33 in the through-hole 27. Coming from above, the upper sleeve portion 32 has a blind hole 31 , towards the lower end an internal thread 33 , which forms part of the screwing 33 . The lower sleeve section 34 has at its lower end a blind hole 39 and above it a threaded bore 38 which runs transversely to the longitudinal axis of the sleeve section 34 and - in the case of sleeve sections 32 , 34 inserted into the through hole 27 - runs perpendicular to the wing plane, that is to say in the x direction. The sleeve 30 has a dimension in the Y direction, which is smaller than the corre sponding dimension of the through hole 27 of the hinge bracket 20 , whereas the sleeve dimension in the x direction, that is, in the direction of the wing plane, corresponds to the corresponding dimension of the through hole 27 . The adjustment of the wing in the Y direction serves to adjust the contact pressure that is present between the wing 2 a and a frame-fixed seal.

In the bore 38 of the sleeve 30 there is a set screw 100 which, together with the sleeve 30, forms the third adjusting means 30 , 100 and rests with its two ends 102 on the inner surface of the through hole 27 and through a comparatively small access hole 29 in the hinge bracket 20 is accessible on the head side and is adjustable by means of a key and, when adjusted, the hinge bracket 20 is adjusted relative to the sleeve 30 in the Y direction. In contrast, the sleeve is fixed in position by the threaded pin 80 and the holding pin 86 and rotation-free against the pin tab 66 . The retaining pin 86 has, for example, a cross-section deviating from the circular shape and thereby ensures that the sleeve 30 is fixed without rotation in the through hole 27 of the hinge bracket 20 and without rotation in the correspondingly cross-sectionally shaped hole 68 of the pin tab 66 .

In the area of the threaded bore 38 and the adjusting screw 100 stored therein, the lower sleeve portion 34 is provided with a countersink 37 , which creates space between the sleeve portion 34 and the threaded bore 38 for the head of the adjusting screw 100 .
