Description

The invention relates to a hinge, in particular for a swing door, with (i) at least one hinge axis element, (ii) a first hinge part and a second hinge part, which are connected to one another in a hinged manner via the at least one hinge axis element, (iii) at least one latching arrangement which has at least a latching device arranged on the second hinge part with a latching body and at least one latching recess arranged on the hinge axis element, wherein the latching device is set up in such a way that the latching body engages in the latching recess in a latched position and (iv) a tensioning means for releasably fixing the hinge axis element on the first Band part in which an angular position of the hinge axis element and the detent recess is adjustable with respect to the first band part.

The angular position of the two hinge parts when the latching body is latched into the latching recess, ie in a latching position, marks a zero point with respect to a swinging of the hinge parts relative to one another or a corresponding door or a corresponding window. This zero point of the pendulum can be shifted by turning the two parts of the belt against each other with the clamping device released. The turning usually takes place when the locking body is locked in the locking recess. In this detent position, the angular position of the hinge axis element with respect to the second hinge part is well defined. Is the origin at the desired angular position of the first Band part opposite the second band part, the corresponding angular position of the joint axis element is fixed with respect to the first band part via the clamping means, whereby the zero point is set.

The document DE 10 2011 088 192 A1 describes a hinge for a swing door, with (i) at least one hinge axis element, (ii) a first hinge part and a second hinge part, which are connected to one another in a hinged manner via the at least one hinge axis element, (iii) at least one latching arrangement which has at least one on the second The latching device arranged on the hinge part has a latching body and at least one latching recess arranged on the hinge axis element, the latching device being set up in such a way that the latching body engages in the latching recess in a latching position and (iv) a tensioning means for releasably fixing the hinge axis element on the first hinge part, in which an angular position of the hinge axis element and the locking recess is adjustable with respect to the first strap part. The clamping means has a locking screw held in/on the bearing element and designed as a threaded pin with a conical tip as a clamping element, which presses on one side via a flank of this tip onto a conical end section of this joint axis element to fix the selected angular position of the joint axis element. The force that occurs during clamping/clamping only acts on a very small line-like area, so that there is a correspondingly high pressure. The one-sided load can lead to a canting/tilting of the joint axis element, so that the force is distributed unevenly over the already small area, so that quite high local pressure can arise.

However, a correspondingly high pressure can lead to pinch marks appearing on the joint axis element. When correcting the zero point setting, clamping marks from previous zero point settings can make the zero point setting more difficult, since the locking means "slides" with its clamping element into the old clamping mark and the zero point setting falls back to an old angular position value.

The publication FR 2 886 965 A1 discloses a hinge having a stationary bracket fixedly mounted to a door frame and including a sliding actuator. A clamp assembly is pivoted to the stationary console, the assembly having a clamp that securely holds a glass door and two pairs of pivot clamp bolts. A trunnion is rotatably mounted through the bracket and two trunnion clamps securely hold a body on the trunnion. The bolts hold the clamps securely on the body, with the hinge loosening the bolts of the pivot clamps and loosening the pivot clamps to align the slide actuator and pivot.

The publication WO 2017/051328 A1 discloses a hinge for pivoting glass doors, in particular for shower cubicles, comprising a stop block having a substantially vertical axis and suitable to be unified with a fixed or supporting auxiliary structure. A hinge misalignment via the axis arranged in the hinge can be compensated by means of a screw arrangement.

It is the object of the invention to specify a hinge in which such problems are at least significantly reduced.

The object is achieved according to the invention by the features of the independent claim.

1. (i) mindestens einem Gelenkachsenelement,
2. (ii) einem ersten Bandteil und einem zweiten Bandteil, die über das mindestens eine Gelenkachsenelement scharnierartig miteinander verbunden sind,
3. (iii) mindestens einer Rastanordnung, die mindestens eine an dem zweiten Bandteil angeordnete Rasteinrichtung mit einem Rastkörper und mindestens eine am Gelenkachsenelement angeordnete Rastausnehmung umfasst, wobei die Rasteinrichtung derart eingerichtet ist, dass der Rastkörper in einer Raststellung in die Rastausnehmung eingreift und
4. (iv) einem Spannmittel für ein lösbares Fixieren des Gelenkachsenelements am ersten Bandteil, bei dem eine Winkelposition des Gelenkachsenelements und der Rastausnehmung bezüglich des ersten Bandteils einstellbar ist,

ist vorgesehen, dass das Spannmittel mindestens ein Paar Klemmbacken zum Einspannen des Gelenkachsenelements zwischen diesen Klemmbacken aufweist, wobei jede der Klemmbacken eine an die Kontur des Gelenkachsenelements angepasste Klemmfläche aufweist. Die beim Spannen/Klemmen auftretenden Kräfte wirken paarweise gegenläufig auf zwei ausgedehnte Flächen, sodass bezogen auf die entsprechende Kraft ein relativ kleiner Anpressdruck entsteht. Durch die paarweise gegenläufig auftretenden Kräfte wird ein Verkippen/Verkannten des mindestens einen Gelenkachsenelements vermieden und es kommt zu einer relativ gleichmäßigen Verteilung der Kräfte über die jeweiligen Flächen, was die Entstehung von Klemmmarken verhindert oder zumindest deutlich reduziert.In the hinge according to the invention, in particular for a swing door, with

1. (i) at least one hinge axis element,
2. (ii) a first strap part and a second strap part, which are hingedly connected to one another via the at least one hinge axis element,
3. (iii) at least one latching arrangement, which comprises at least one latching device arranged on the second strap part with a latching body and at least one latching recess arranged on the hinge axis element, the latching device being set up in such a way that the latching body engages in the latching recess in a latched position and
4. (iv) a tensioning means for releasably fixing the hinge axis element to the first strap part, in which an angular position of the hinge axis element and the locking recess can be adjusted with respect to the first strap part,

it is provided that the clamping means has at least one pair of clamping jaws for clamping the joint axis element between these clamping jaws, each of the clamping jaws having a clamping surface adapted to the contour of the joint axis element. The forces occurring during clamping/clamping act in pairs in opposite directions on two extensive surfaces, so that a relatively small contact pressure is created in relation to the corresponding force. Due to the forces acting in opposite directions in pairs, tilting/canting of the at least one joint axis element is avoided and this occurs to a relatively even distribution of forces over the respective surfaces, which prevents or at least significantly reduces the formation of pinch marks.

According to a preferred embodiment of the invention, the clamping surfaces of each pair of clamping jaws jointly overlap the circumference of the joint axis element in a corresponding axis section by at least 33%, preferably by at least 50%. In the case of 33%, for example, these are two opposing circumferential arcs of 60° each, i.e. 120° (= 33% of 360°) together. At 50%, these are two mutually opposite circumferential arcs of 90° each, i.e. 180° together. The clamping marks that occur with these dimensions are usually hardly detectable.

According to a further preferred embodiment of the invention, the clamping means has a fixed clamping state with a well-defined clamping force of the clamping jaws with respect to the hinge axis element. The clamping means can optionally be brought into this state and also kept in this state. The clamping force can be selected in such a way that a clamping mark in a hinge with such a tensioning device could lead to a reduced clamping force, but not to "sliding into" the old clamping mark.

According to yet another preferred embodiment of the invention, the clamping means has two clamping means parts, each part comprising one clamping jaw for each pair of clamping jaws. In other words, n (with n=1, 2, ...) pairs of clamping jaws are formed using only two clamping means parts. The two clamping devices must be able to move in relation to one another.

According to a further preferred embodiment of the invention, it is provided that the clamping means has at least one device for fixing a relative position of the clamping means parts to one another, in particular in the form of a screw connection, in which the clamping jaws clamp in an angular position of the joint axis element fixing clamping position. This is then the "fixed clamping condition" referred to above.

Furthermore, it is advantageously provided that each of the two clamping means parts that can be moved relative to one another has a base and at least one arm on which the clamping jaw for the corresponding pair of clamping jaws is arranged at a distance from the base. Unlike the document mentioned at the beginning DE 10 2011 088 192 A1 the screw connection is not used here directly for clamping/clamping, but for fixing the relative position of the clamping device parts to one another by fastening the clamping device parts to one another.

In this case, it is advantageously provided that the device for determining a relative position of the clamping means parts with one another acts on the base of the clamping means parts involved. If this device is a screw connection, then this is preferably a central screw connection, in particular by means of only one screw.

Furthermore, it is provided in particular that the clamping means parts comprise the base and two arms which are arranged in a U-shape. Via this U-shape, the two clamping means parts that can be moved relative to one another can, for example, clamp a single joint axis element in place at its two ends.

According to yet another preferred embodiment of the invention, the contour of the at least one joint axis element is circular-cylindrical, with the clamping surfaces of the clamping jaws being adapted accordingly. For this purpose, each of the clamping jaws forms, for example, a kind of half-shell in relation to its respective clamping surface.

Furthermore, it is preferably provided that the latching device has a device for applying force to the latching body. It is advantageously provided that the

Device for applying force to the locking body comprises a spring device, in particular a compression spring. Such spring loading has proven itself in practice. In the following, the invention is explained by way of example with reference to the accompanying drawings using preferred exemplary embodiments.

a comparison of the Figures 3 and 4 shown states of the hinge in a plan view.

The 1 shows the assemblies of a hinge 10, more precisely a hinge for a (not shown) swing door, in particular a glass swing door. The first assembly has a first strap part 12 and a tensioning means 14 . The second assembly has a second band part 16 and a bearing unit 18 fastened to the second band part 16 and in which a pin-like joint axis element 20 is rotatably mounted via a bearing bush 22 . The joint axis element 20 protrudes with its end sections 24, 26 on opposite sides of the bearing unit 18. Inside the storage unit 18 results in an in 2 latching arrangement 28 shown, via which a zero point of the pendulum movement of the swinging door is defined. The clamping means 14 has two clamping means parts 30, 32 that can be separated from one another, of which the first clamping means part 30 is fastened to the first belt part 12, while the second clamping means part 32 can be detachably fastened to the first clamping means part 30 via a screw connection 34 . The screw connection 34 forms, together with projection-recess arrangements, a device for fixing a relative position of the clamping means parts to one another.

Here in the example shown, the first hinge part 12 is a hinge part for a door leaf of the swing door and the second hinge part 16 is a hinge part for attachment to a door frame, a wall or another fixed element. Alternatively, it is also possible and also common in corresponding configurations that the second hinge part 16 is the hinge part for the door leaf of the swing door and the first hinge part 12 is a hinge part for attachment to a corresponding fixed element. The two band parts 12 , 16 are connected to one another in the manner of a hinge within the assembled hinge band 10 via the hinge axis element 20 . As already mentioned, a zero point of the pendulum movement of the swinging door results from a detent position of the detent arrangement 28 . In order to assign this zero point to an angular position of the swing door or of the first hinge part 12, the joint axis element 20 can be detachably fixed to the first hinge part 12 via the clamping means 14 in such a way that a desired angular position of the joint axis element 20 with respect to the first hinge part 12 can be adjusted.

Each of the clamping means parts 30, 32, which can be moved relative to one another, has a U-shape with a base 36 and two arms 38, 40, with the screw connection 34 taking place on the base 36 in each case. The clamping means 14 has a total of two pairs of clamping jaws 42, 44, 46, 48, of which one pair (with the clamping jaws 42, 44) the joint axis element 20 at its one end portion 24 and the other pair (with the clamping jaws 46, 48) can encompass the joint axis element 20 at its other end section 26 and releasably clamp it. Each of the clamping means parts 30, 32 in one Middle portion of its arms 38, 40 each have a jaw 46, 48 per pair of jaws 42, 44.

The 2 shows a section through the second assembly of the hinge 10, the section going through the bearing unit 18 at the level of the hinge axis element 20. In addition to the joint axis element 20 and the bearing bushing 22 for supporting the joint axis element 20, the bearing unit 18 also contains the locking arrangement 28, which has a locking device 50 with a locking body 52 and a device 54 for applying force to the locking body 52 and a locking recess formed in the joint axis element 20 56 included. The device 54 for applying force to the detent body 52 is essentially a compression spring 58 which presses the detent body 52 in the direction of an axis section of the joint axis element 20 in which the detent recess 56 is formed. In other words, the locking device 50 is set up in such a way that the locking body 52 engages in the locking recess 56 in a locking position.

The angular position of the two hinge parts 12, 16 when the latching body 52 is engaged in the latching recess 56, i.e. in a latching position, marks a zero point with respect to an oscillating movement of the hinge parts 12, 16 relative to one another or a corresponding door or a corresponding window. This zero point of the pendulum can be shifted by twisting the two belt parts 12, 16 against each other with the clamping means 14 released. The turning usually takes place when the locking body 52 is locked in the locking recess 56. In this locking position, the angular position of the joint axis element 20 with respect to the second hinge part 12 is well-defined. If the zero point is at the desired angular position of the first hinge part 12 in relation to the second hinge part 16, the corresponding angular position of the joint axis element 20 in relation to the first hinge part 12 is fixed via the clamping means 14, whereby the zero point is set. For this purpose, the screw of the screw connection 34 is simply tightened at the appropriate angular position.

The 3 shows a view of the hinge 10 with loosened tensioning means 14. In this view it can be seen that the free ends of the mutually associated arms 38, 40 of the two tensioning means parts 30, 32 form joints 60, 62 with respect to a common axis of rotation 64. The clamping means parts 30, 32 can be pivoted relative to one another with respect to this axis 64. The hinge axis member 20 is not fixed with respect to the first band portion 12 .

The 4 shows a view of the hinge 10 with fixed clamping means 14 and with the joint axis element 20 fixed by clamping means 14. The joints 60, 62 are on one side of the clamping jaws 42, 44, 46, 48 and the screw connection 34 is on the other side of the clamping jaws 42 , 44, 46, 48 arranged. This results in a large lever and thus also a high clamping force.

The figure 5 finally shows in a comparison in the Figures 3 and 4 shown states of the hinge 10 in a plan view. It is clearly visible that the clamping surfaces of the clamping jaws 40, 42; 46, 48 of each pair of the circumference of the joint axis element 20 in the corresponding axis section 24, 26 together almost completely, ie more than 90%, overlap.
