Description

The invention relates to a hinge strap of a band hinged to a hinge axis connection of a wing to a frame, with a longitudinal recess, arranged in the longitudinal recess with a hinge axis parallel to the laterally offset axis of rotation by means of a rotary tool rotatable bearing bush having a Lagerbuchsenausnehmung for receiving a hinge pin defining the hinge axis comprises, with a provided in the operating position at least in the lower region of the longitudinal recess internal thread, and having an external thread, screwed into the internal screw lifting spindle having a support side for direct or indirect support of the bearing bush and / or the hinge pin.

The document EP 2 607 589 A2 discloses such a hinge flap according to the preamble of claim 1, wherein the axis of rotation of the bearing bush laterally offset longitudinal axis of the Lagerbuchsenausnehmung, in other words: the effective outer periphery of the bearing bush eccentric arrangement of the Lagerbuchsenausnehmung, creating the possibility to adjust the sealing pressure, ie shifting the wing in a direction perpendicular to its front surface facing relative to the frame.

In order to accomplish the required rotation of the bearing bush, in the known door hinge first, the lifting spindle, on which the bearing bush and / or the hinge pin are supported, must be completely unscrewed while sacrificing the height adjustment. At the then accessible, based on the operating position lower end of the bearing bush, on which a suitable key surface is provided, then a separately vorzuhaltendes rotary tool can be used to rotate the bearing bush in the longitudinal recess, and from a center position by up to + / - 90 °.

After this rotation of the desired sealing pressure is reached, the new height adjustment takes place in that the lifting spindle is screwed as far into the longitudinal recess until the bearing bush and / or the hinge pin supporting, other hinge tabs for the correct height adjustment of the wing in the Frame has reached the required position.

A disadvantage of this generic tape that a separate turning tool is required for rotation of the bearing bush in the longitudinal recess.

The documents EP 0 860 571 A1 and EP 2 402 533 A2 also disclose a hinge strap with a rotatable and liftable bushing.

The invention is therefore based on the object to provide an improved hinge strap.

This object is achieved by the reproduced in claim 1 hinge flap.

The fact that the lifting spindle itself is designed as a selectively attachable rotary auxiliary means, can be dispensed with a separately vorzuhaltendes rotary tool. The lifting spindle is therefore used as a turning tool itself. It is therefore effectively avoided that a Dichtungsandruckeinstellung is impossible due to the lack of a suitable turning tool.

If the bearing bush recess is formed in such a way that its longitudinal axis is arranged laterally offset from the axis of rotation, the hinge pin can be in the form of a straight component be formed over its entire length constant, circular cross-section.

In order to be able to use the lifting spindle as a selectively attachable turning aid, according to the invention a key face is provided on the bearing bush and a counter key face which can be brought into operative connection with the key face is provided on the lifting spindle. If the mating key surface is located on the opposite side of the lifting spindle from the support side, the lifting spindle can be used in their function as a turning tool by first completely unscrewed from the longitudinal recess and vice versa, i. now facing away from the bearing bush and / or the hinge pin with the support side, is attached to the bearing bush. If the external thread of the lifting spindle is outside the longitudinal recess, it can now form the handle of the turning tool.

Particularly preferred is a development of the hinge flap according to the invention, in which the longitudinal recess has at least one radial detent recess. At the bearing bush then preferably at least one locking projection is provided which can be brought into operative connection with the latching recess. If only a single detent recess and a single detent projection are provided, then these are preferably arranged such that they are in operative connection in the middle position, i. the locking defines the middle position, from which the bearing bush can be rotated by +/- 90 °. Preferably, however, a plurality of locking recesses and locking projections are provided, for example, arranged offset by 90 ° or 45 ° about the axis of rotation. A snap takes place at a rotation of the bearing bush in the longitudinal recess then every 90 ° or every 45 °, whereby exactly defined positions of the bearing bush are easier to find and maintain.

Particularly preferred is a development of the hinge flap according to the invention, in which the lifting spindle is designed such that the at least one latching projection is locked in operative connection with the at least one latching recess when the bearing bush and / or the hinge bolt in indirectly or immediate contact with the support side. This prevents that during a rotation of the lifting spindle for the purpose of height adjustment, the bearing bush rotates undesirable, which would otherwise lead to an undesirable change in Dichtandrucks.

In order to effect this locking, the lifting spindle can have an annular projection surrounding the support side, which engages behind the at least one latching projection when the bearing bush and / or the hinge bolt are in direct or indirect contact with the support side.

On the support side opposite side of the lifting spindle, an annular rim may be provided which engages in a provided on the bearing bush or formed between the bearing bush and the hinge part annular groove when the key and the counter key surfaces are in operative connection. Due to this measure, the "seat" of the lifting spindle on the bearing bush, when the lifting spindle serves as a rotation aid, can be improved against unwanted loosening during the turning process.

In order to increase the maximum torque which can be transmitted to the bearing bushing from the lifting spindle serving as a turning aid, the edge and the bearing bushing can comprise means for transmitting torques between the edge and the bearing bush.

The means may be operatively connected by at least one protrusion provided on the edge or at least one recess provided on the edge and by at least one complementary recess or at least one complementary protrusion of the bearing bush when the key and counter key surfaces are engaged.

Thus, the lifting spindle can not automatically solve their function as a rotary tool from the bearing bush, a locking device and on the bearing bush a counter-locking device are preferably provided on the side of the mating key surface.

The latching device may be a latching projection and the mating latching device may be a latching recess, such that the lifting spindle can be placed under overcoming a latching force on the bearing bushing by engaging the key surface and mating key surface or separating the key surface and mating key surface from the bearing bushing.

In a constructive, preferred variant, the latching projection extends radially outwards from the counterkey surface.

The counter-latching recess can be provided in the contour of the bearing bush forming the key surface.

It is particularly preferred if two with respect to the axis of rotation by 180 ° staggered latching and counter-locking devices are provided, as this is a particularly effective protection against automatic release is effected.

In order to facilitate the placement of the lifting spindle on the bearing bush in its function as a rotation aid, the counter-locking devices are preferably arranged in certain angular relationships to the lateral offset of the longitudinal axis and the axis of rotation. If, for example, the bearing bushing is in a predefined "zero position" when the band strap is delivered, then the user is unambiguously given the orientation in which the counter-locking devices are located. The lifting spindle in its function as a rotation aid can then be placed specifically without failures, even if due to the installation situation, the front end of the bearing bush on which the lifting spindle is placed, can not be optically detected.

In order to detect the direction of the lateral offset between the longitudinal axis of the recess of the bearing bush and the axis of rotation thereof in the hinge strap optically unambiguous, the direction of this lateral offset is preferably on the side facing away from the key surface end face of the bearing bush optically highlighted by a first mark. By looking at the hinge tab from the top can thus be checked in a simple manner, whether the bearing bush, for example, is in its zero position.

In addition, it is particularly preferred if at least one second marking is provided on the support side of the lifting spindle, which is arranged in a certain angular relationship to the latching device. Due to this measure, the placement of the lifting spindle is facilitated in its function as a rotary tool on the bearing bush again.

The exemplary embodiment of a hinge strap 100 according to the invention shown in the drawing is part of a hinge hinge-hinged about a hinge axis S connection of a wing, not shown, to a frame. The hinge flap 100 is shown as a frame hinge flap.

It comprises a fastening part 1, which is the attachment - in the illustrated embodiment on the frame - is used. On the fastening part 1, a hinge part 2 is formed. The hinge part 2 comprises a longitudinal recess 3, in which a bearing bush 4 is provided. The latter is rotatably arranged about an axis of rotation D parallel to the hinge axis S, but laterally offset, by means of a rotary auxiliary means to be described in detail below.

The bearing bush 4 has a Lagerbuchsenausnehmung 5 with a longitudinal axis T, which is laterally offset from the axis of rotation D and coincides with the hinge axis S in the illustrated embodiment. The Lagerbuchsenausnehmung 5 is in other words arranged centrally with respect to the effective outer periphery of the bearing bush 4. With "effective outer circumference" is the outer periphery which defines the axis of rotation D of the bearing bush 4 in the longitudinal recess 3.

In the longitudinal recess 3, an internal thread 7 is provided. In this internal thread 7 - based on the operating position of the hinge strap - from below a lifting spindle 6, which has a female thread 7 to the complementary external thread 8, screwed. The lifting spindle 6 points to its in the in Fig. 1 to 7 illustrated operating position upper, the bearing bush 4 side facing a support side 9, on which the bearing bush 4 is supported. The support side 9 is surrounded by an annular projection 10th

How out Fig. 1 is apparent, the bearing bush 4 can be in the longitudinal recess 3 of the hinge part 2 in the direction of the arrow P relocate by the lifting spindle 6 is further screwed from below into the longitudinal recess 3 or further unscrewed down. To effect the screwing operation, the lifting spindle has a measure for applying a rotary tool, which is designed as a hexagon socket 11 in the illustrated embodiment.

As already mentioned above, the bearing bush recess 5 is arranged eccentrically to the effective outer circumference of the bearing bush 4. If the bearing bushing 4 is rotated within the longitudinal recess 3, then the longitudinal axis T and thus the hinge axis S is displaced relative to the hinge part 2. As a result, the other hinge tabs - in this case the hinge hinge tabs - are displaced relative to the hinge tab 100 perpendicular to the axis of rotation D. whereby, for example, a seal pressure change can be achieved.

In order to effect the rotation of the bearing bush 4 in the longitudinal recess 3 - as symbolized by arrow O - are at the lower end of the bearing bush 4 designed as a hexagon key surface 13 and on the support side 9 opposite side of the lifting spindle 6 as a complementary hexagon trained counter key surface 14 is provided. The rotary actuation of the bearing bush 4 can therefore be done by the lifting spindle 6 first from its in Fig. 1 and 5 completely unscrewed position, turned by 180 ° and then in the in Fig. 8 and 12 illustrated reversed position is attached to the bearing bush 4, so that the counter key surface 14 is in operative connection with the key surface 13. The external thread 8 can then - if it protrudes from the hinge part 2 - to serve as a handle. Or it can be used for rotary actuation, not shown in the drawing rotary tool, which is adapted to the hexagon socket 11, use.

In order to improve the seat of the lifting spindle 6 on the bearing bush 4 in this "rotational actuation position", an edge 15 surrounding the counter key surface 14 is provided, which engages in an annular groove 16 provided on the bearing bush 4.

As in particular in Fig. 3 can be seen, are distributed in the longitudinal recess 3 over the circumference, offset by 90 ° to each other, four radial locking recesses 17 are provided. Complementary latching projections 18 are also provided offset by 90 ° to one another on the bearing bush 4. The locking projections 18 are elastically formed so that they shift back and release the rotation of the bearing bush 4 in the longitudinal assembly 3 when a certain torque is exceeded.

The latching projections 18 are designed such that they are engaged behind by the annular projection 10 of the lifting spindle 6 when it is screwed into the internal thread 7 in its operating position in which the bearing bush 4 is supported on the support side 9. Because of this measure, it is reliably prevented that the bearing bush 4 can rotate within the longitudinal recess 3, if due to a frictional connection by supporting on the support side 9 of the lifting spindle 6, a torque is exerted on the bearing bush 4 during a Höhenjustiervorganges in the direction P.

Fig. 15 shows a further embodiment of a lifting spindle 6. It differs from the lifting spindle 6 in that four inwardly directed projections 19 are provided on the edge 15, which in complementary recesses 20 (s. Fig. 10 ) engage the bushing 4 when the lifting spindle 6 serves as a rotation aid for rotational actuation of the bearing bush 4. By the engagement of the projections 19 in the recesses 20, the maximum torque, which can be transmitted through the lifting spindle 6 on the bearing bush 4, can be increased.

Another embodiment of a lifting spindle 6 is in the Fig. 16 to 20 shown. To avoid repetition, only the differences from the first embodiment described above are mentioned below. The description of the first embodiment is hereby fully incorporated by reference. Unlike the particular in Fig. 6 and 13 illustrated, the first embodiment of the lifting spindle, the counter key surface 14 is not formed as an external hexagon, but gear-like. Between the counter-key surface 14 and the edge 15 extend with respect to the rotation axis D opposite one another latching projections 23 which form part of a arranged on the side of the mating key surface latching device 21.

As in particular in Fig. 18 can be seen, the locking projections 23 in the direction of the rotation axis D slightly over the edge 15 via. It has a "bulbous" shape in cross-section, in order to interact with a provided in the bearing bush 4 mating latching means 22 latching, as will be described below.

Finally, on the external thread 8 of the lifting spindle in an opposite and with respect to the latching projections 23 about the rotation axis D offset by 90 ° two flat surfaces 28 for attachment of a rotary tool, not shown in the drawing for rotating the lifting spindle 6 is provided in its function as a rotation aid.

In the FIGS. 22 to 25 shown, for use together with in Fig. 16 to 20 shown bearing bush comprises an outer part 29 made of a dimensionally stable plastic, in which an inner part 30 is inserted from a friction-reducing plastic for supporting a hinge pin, not shown in the drawing.

At the according to FIGS. 22 to 24 lower end comprises the bearing bush 4 in further difference from the particular with reference to Fig. 1 and 3 described embodiment, a key surface 13 which is approximately complementary to the counter key surface 14 and thus formed like a ring gear. Opposite one another, a counter-latching device 22 for the latching device 21 of the lifting spindle 6 is formed in the contour 31 forming the wrench surface 13.

The counter-latching device 22 comprises two mutually oppositely disposed latching recesses 24, which are formed approximately complementary to the latching projections 23 and thus have a constriction 32, under the elastic extension of the "bulbous" latching projections 23 selectively inserted or removed by displacement of the lifting spindle in the direction of the rotation axis D. are.

To facilitate the finding of the correct rotational positions with respect to the axis of rotation D for placing the lifting spindle 6 in its function as a rotation aid, is - how Fig. 25 is removable - at the according FIGS. 22 to 24 upper end face 25, a first mark 26 is arranged in the form of an outwardly directed arrow. This first marking 26 points in a direction perpendicular to the connecting plane between the latching recesses 22, in which also the axis of rotation D and the hinge axis S or longitudinal axis T are offset from each other. As a result, the current adjustment position can be recognized by a user with the aid of the first marking 26.

As in Fig. 17 can be seen, a second mark 27 is provided in the form of two recesses on the support side 9 of the lifting spindle 6. The two recesses are arranged opposite to the two locking projections 23, so that they characterize their position and thus the lifting spindle can be brought to place in their function as a rotary tool in the required position for latching.
