Description

The invention relates to a hinge for the pivotable connection of a closing element, in particular a door, to a frame, in particular a door frame, with a first hinge element for arrangement on the closure element, a second hinge element for arrangement on the frame and a movable between a locking position and an unlocking position Locking element, wherein the locking element articulates the two hinge elements together in the locking position and wherein the two hinge elements can be detached from one another in the unlocking position. The invention further relates to a locking device with a locking element which is arranged on a frame so as to be pivotable via a hinge.

Hinges have been used for a long time to connect two elements together. Typically, closing elements, such as doors, hatches, flaps, windows or lids, are articulated to a fixed frame via a hinge, so that the closing elements can be pivoted relative to the frame and can thus be opened and closed as desired.

In order to enable a corresponding articulated connection between the closing element and the frame, hinges generally have two hinge elements, one of the hinge elements being connected to the closing element and the other hinge element being connected to the frame. By means of an articulated connection of the two hinge elements, the closing element and the frame are then also articulated to one another.

In order to connect the two hinge elements together, locking elements can also be used in addition to simple plug-in connections. These are usually between a locking position, in which the two hinge elements are locked or connected to one another in an articulated manner, and an unlocking position, in which the two hinge elements are not locked or connected to one another, so that the hinge elements can be separated from one another. and movable. In the unlocking position, the closing element can then be removed from the frame, for example.

A corresponding hinge is in the DE 20 2011 103 492 U1 shown. In this hinge, a locking element in the form of a rotatable tongue is provided for selectively locking the two hinge elements. Although the two hinge elements can be connected to one another in an articulated manner using the tongue, such a tongue lock has proven to be less practical in practice, as there is often limited space in the area of the hinge, which can make it difficult to turn the tongue and often also the use of one require tools.

Based on this, the invention sets itself the task of specifying a hinge which is characterized by a simplified locking and unlocking of the two hinge elements.

This task is achieved with a hinge of the type mentioned in that the locking element can be moved linearly back and forth between the locking position and the unlocking position.

The linear movement of the locking element creates a very simple way of both locking and unlocking the two hinge elements. If the closing element is to be mounted on a frame, after aligning the closing element and thus also the alignment of the hinge elements, the locking element only needs to be moved in a linear direction and transferred from the unlocking position to the locking position. The two hinge elements are then locked together in an articulated manner, so that they can be pivoted relative to one another about the hinge axis, but cannot be separated from one another. If the locking element is to be dismantled from the frame, the locking element simply needs to be moved in the opposite direction from the locking position to the unlocking position. In this case, the two hinge elements are no longer connected or locked together, so that the closing element can be removed from the frame.

With regard to the movement of the locking element between the locking position and the unlocking position, it has proven to be advantageous if the linear movement of the locking element is limited. The locking element can therefore only be moved back and forth between the locking position and the unlocking position and not beyond, which enables a well-defined movement of the locking element. The locking and unlocking positions can therefore each represent an end position. Due to the limitation, the assembly and disassembly of the locking element is simplified, since the locking element can be easily moved between the locking position and the unlocking position can be moved back and forth.

From a design point of view, it has proven to be advantageous if two stops are provided to limit a linear movement of the locking element. The stops can be used to reliably prevent movement beyond the locking position or the unlocking position. One stop can be assigned to the locking position and the other stop can be assigned to the unlocking position. The stops can be part of the first hinge element or part of the locking element, as will be described further below.

According to an advantageous development of the invention, it is proposed that the second hinge element has a guide element, in particular a guide pin, for guiding the locking element. The guide element prevents the locking element from tilting during a linear movement between the locking position and the unlocking position and thus ensures reliable functionality.

With regard to the guide element, it has also proven to be advantageous if it extends through the locking element. This configuration ensures sufficient stability, which in turn ensures reliable functioning or movement of the locking element. Furthermore, the guide element can also engage in the locking element to limit movement and thus prevent movement beyond the locking position or the unlocking position. From a structural point of view, the guide element can be designed as a guide pin, in particular as a continuous guide pin. The guide element can extend through the locking element and can be mounted at both ends in the first hinge element, so that the guide element can be designed to be stationary together with the first hinge element in relation to the closing element. The guide pin can have a round cross-section, but other cross-sectional shapes are also possible.

With regard to the design of the locking element, it has proven to be advantageous if it has a recess, in particular an elongated hole, into which the guide element extends. When the locking element moves relative to the first hinge element, the recess can move relative to the fixed guide element, wherein the guide element can move relative to the recess in the latter. The design as an elongated hole has proven itself from a constructive point of view, as it ensures reliable guidance of the locking element and is comparatively easy to manufacture.

With regard to the recess, it has proven to be advantageous if it is designed as a guide to guide a linear movement of the locking element. By designing it as a guide, a reliable linear movement of the locking element between the locking position and the unlocking position can be ensured. Tilting or wedging of the locking element in the first hinge element can thus be reliably prevented.

According to an advantageous development of the invention, it is proposed that the recess has two stops for limiting the linear movement of the locking element. The stops can represent the two ends of the recess, so that the guide element rests against one stop in the locking position and against the other stop in the unlocking position. Any movement beyond this is then prevented by the stops. With an elongated hole, the two round ends can form the stops. The guide element can rest against one stop in the locking position and against the other stop in the unlocking position. During a linear movement of the locking element, the guide element can move back and forth between the stops relative to the locking element or the locking element can be moved in a linear direction in such a way that the recess between the two stops moves around the fixed guide element.

According to an advantageous development of the invention, it is proposed that the locking element can be tilted back and forth about a tilt axis between the unlocking position and a tilt position. To unlock the two hinge elements, the locking element can first be moved in a linear direction from the locking position into the unlocking position and then tilted from the unlocking position into the tilting position. In the tilted position, the two hinge elements continue to be unlocked, so that the locking element is also in the tilted position in a position that unlocks the two hinge elements.

It has proven to be advantageous if the tilt axis extends parallel to the hinge axis. This design only requires one small installation space and is characterized by a compact design. The tilt axis can extend through the guide element or the guide pin. Both the hinge axis and the tilt axis can extend parallel to the closing element or to the closing element surface. The direction of movement of the locking element can extend perpendicular to the hinge axis, so that the locking element is moved perpendicularly towards or away from the hinge axis during a movement between the locking position and the unlocking position.

To ensure a reliable tilting movement, it has proven to be advantageous if the locking element can be tilted back and forth around the guide element. The guide element can therefore have a dual function and can serve both to ensure a reliable linear movement and to ensure a reliable tilting movement. The locking element can first be transferred from the locking position into the unlocking position, in which the guide element rests on one of the two stops of the recess of the locking element, and in a next step the locking element can then be transferred into the tilting position about the tilt axis or around the guide element .

With regard to the tilting position, it has proven to be advantageous if the locking element is secured against linear movement in the tilting position. In this respect, the locking element cannot be transferred from the tilted position directly into the locking position, but in order to lock the two hinge elements together, it must first be tilted from the tilted position into the unlocked position and then transferred from there in a linear direction back into the locking position. The locking element can be locked in the tilt position. Preventing the locking element from being transferred directly from the tilting position into the locking position prevents the locking element from being accidentally locked. In addition, since a direct transfer from the tilting position to the locking position is not possible, the locking element can be secured in the tilting position against unintentional movement, in particular into the locking position.

From a structural point of view, it has proven to be advantageous in order to prevent a corresponding movement of the locking element if the locking element is locked in the tilting position with the second hinge element. The locking element is held or secured in the tilting position by appropriate latching and can therefore not be moved into the locking position independently or unintentionally. Structurally, the locking element can be positively connected to the first hinge element, for example by locking the locking element in or on the first hinge element in the tilt position. This is advantageous, especially if the closing element is attached to a frame via several hinges, since it is not necessary to hold the various locking elements of the hinges in the unlocked position, but rather these can be transferred from the unlocked position to the tilted position. The locking element thus remains in the tilting position, into which the two hinge elements can be released from one another, even without constant force.

It has also proven to be advantageous if the locking element is biased into the locking position via a spring. The spring can ensure a secure locking of the two hinge elements, since the locking element is correspondingly biased into the locking position by the spring. In the event of an unintentional movement of the locking element in the direction of the unlocking position, the spring ensures that the locking element automatically returns to the locking position. Only by transferring the locking element from the unlocking position to the tilting position is it achieved that the locking element no longer has to be actively held against the force of the spring. In the tilted position, the spring, in conjunction with the latching mechanism, ensures that the locking element is held in the tilted position. In this respect, the spring has a dual function.

It has also proven to be advantageous if the locking element has a recess for locking with the second hinge element, into which the second hinge element can engage. By tilting the locking element, the locking recess can be positioned in such a way that it engages behind the second hinge element, so that the second hinge element basically engages in the recess. The locking element or the recess can have a locking contour which, in the tilt position, can interact with a counter contour on the hinge side, so that the locking element is held or secured in the tilt position and prevents movement of the locking element into the locking position. The locking element or the locking contour or the recess can be pressed against the second hinge element by the spring, which will be described in more detail below. Particularly due to the emerging existing frictional forces, the preload force of the spring can ensure that the locking element is reliably held in the tilt position.

Furthermore, it has proven to be advantageous if the locking of the locking element is released when the locking element is transferred from the tilting position to the unlocking position, so that the locking element is automatically transferred into the locking position due to the compressive force of the spring. In this respect, only a small tilting movement of the locking element from the tilting position into the unlocking position is required in order to automatically transfer the locking element into the locking position using the force of the spring. The tilt angle by which the locking element can be tilted back and forth between the unlocking position and the tilt position is advantageously small. This tilt angle is preferably below 30 degrees, particularly preferably below 20 degrees and very particularly preferably below 10 degrees. As soon as the latching connection between the locking element and the second hinge element is released, the locking element can snap shut automatically due to the spring. In order to lock, the locking element only needs to be tilted by a small tilting angle from the tilted position into the unlocked position. Especially when the closing element is connected to the frame via a large number of hinges, this very simple locking of the two hinge elements is advantageous and only requires a very short time.

With regard to the second hinge element, it has proven to be advantageous if it has a hinge pin forming a hinge axis. The first hinge element or the closing element can be pivoted about the hinge axis relative to the second hinge element or relative to the frame, for example to open or close the closing element. The hinge pin can extend in the vertical direction, so that the hinge axis then also runs vertically and, for example, along the long side of the door. However, a different orientation of the hinge pin or the two hinge elements is also conceivable.

In a further development of the first hinge element, it has proven to be advantageous if it has a hinge pin receptacle for receiving the hinge pin. When the two hinge elements are locked, the hinge axis can run centrally through the hinge pin receptacle. The hinge pin receptacle can be U-shaped and encompass the hinge pin at least in sections. The hinge pin can be inserted into the hinge pin receptacle in one direction or the first hinge element can be applied to the hinge pin in one direction so that it is arranged in the hinge pin receptacle.

To ensure reliable locking of the two hinge elements, it has proven to be advantageous if the locking element secures the hinge pin in the locking position in the hinge pin receptacle. If the hinge pin is secured accordingly, the two hinge elements are locked together and they can then only be rotated relative to one another. A translational relative movement of the two hinge elements is then no longer possible.

To secure the hinge pin, it has also proven to be advantageous if it is positively encompassed by the hinge pin receptacle and the locking element located in the locking position. This configuration ensures that the hinge pin is reliably secured, so that the two hinge elements are connected to one another in an articulated manner. The wrap angle of the hinge pin receptacle and the locking element is advantageously greater than 180 degrees, so that the two hinge elements can no longer be separated from one another.

With regard to the locking element, it has also proven to be advantageous if it has a locking contour to secure the hinge pin in the hinge pin receptacle. The locking contour can be arranged at the end and can at least partially surround the hinge pin in the locking position and cannot surround it in the unlocking position or in the tilt position.

With regard to the design of the locking contour, it has proven to be advantageous if it is essentially U-shaped. In relation to the hinge pin receptacle, the locking contour can be rotated by 90 degrees, so that the wrap angle formed by the hinge pin receptacle and the locking contour of the locking element is as large as possible. The wrap angle is preferably greater than 270 degrees. The locking contour can be designed in the shape of a mouth and can be moved towards or away from the hinge pin receptacle by a linear movement of the locking element. Both the hinge pin receptacle and the locking contour can be designed to be round, at least in sections, and can therefore be adapted to the shape of the hinge pin.

According to an advantageous development of the invention, it is proposed that the locking contour is designed in such a way that it pushes the first hinge element away from the hinge pin when the locking element is transferred from the unlocking position to the tilting position. Due to the tilting movement, the locking element or the locking contour can come into contact with the fixed hinge pin and then push the first hinge element away from the second hinge element or the hinge pin. This configuration initiates a translational movement of the two hinge elements and thus provides a solution aid for releasing the two hinge elements.

In order to simplify locking the two hinge elements, it has proven to be advantageous if the locking contour is designed in such a way that it comes into contact with the hinge bolt when the hinge elements are plugged together and the locking element is thereby transferred from the tilted position into the unlocked position. When the locking element is released from the frame, the locking element or elements can be in the tilt position. If the locking element is then positioned in such a way that the hinge bolts are arranged in the hinge bolt receptacles, the hinge bolts can contact the locking contour of the locking element and tilt it about the tilt axis from the tilt position into the unlocked position. Due to the compressive force of the spring, the locking element can then be automatically moved into the locking position and lock the two hinge elements together. A manual transfer of the locking element from the tilting position to the unlocking position is then not necessary.

From a design point of view, it has proven to be advantageous if the locking contour has a pressure lug for contacting the hinge pin. When releasing the two hinge elements and when transferring the locking element from the unlocking position to the tilting position, a radial force can be exerted on the hinge pin via the pressure lug, so that the locking element or the first hinge element is pushed away from the hinge pin or the second hinge element. The pressure force can act in the direction of the opening of the hinge pin holder. When the two hinge elements are plugged together or when locking, the pressure lug can be moved in the opposite direction by the hinge pin and the locking element can thereby be tilted about the tilt axis into the unlocking position.

With regard to the pressure nose, it has proven to be advantageous if it is designed as a one-sided locking contour extension. In the unlocking position, the push lug can initially be arranged next to the hinge pin and by moving the locking element into the tilt position, the push lug can then push the first hinge element away from the hinge pin. The pressure lug and the locking recess can lie opposite one another with respect to the guide element, so that the guide element represents the pivot point or the axis of rotation of the locking element. The locking element can therefore be designed in the manner of a rocker.

With regard to the second hinge element, it has proven to be advantageous if it has at least one, in particular two, bearing eyes in which the hinge pin is received. The hinge pin can be fastened or held in the two bearing eyes. The two bearing eyes can attack the upper and lower ends of the hinge pin and thus give it sufficient stability. If the two hinge elements are locked together, the locking element can be arranged between the two bearing eyes

In order to ensure reliable support of the closing element relative to the frame, it has proven to be advantageous if the first hinge element is supported on one of the two bearing eyes. The first hinge element can advantageously be supported on the lower of the two bearing eyes, so that the weight force from the first hinge element or the weight force from the door can be introduced via the corresponding bearing eye into the second hinge element and thus into the frame.

Since frictional forces arise between the first and second hinge elements during an opening or closing movement of the closing element, a washer that reduces the friction between the two hinge elements can be provided. The washer can be arranged between the two hinge elements. The washer is advantageously arranged on the hinge pin and between the lower bearing eye and the first hinge element, so that the washer lies in the flow of force from the first hinge element to the second hinge element.

Furthermore, it has proven to be advantageous if the locking element is guided in one of the two hinge elements. In particular, the locking element can be guided in the second hinge element, which in this respect Linear guide for the hinge element is used. Together with the guide element, the first hinge element can ensure reliable movement of the locking element so that it cannot tilt. The first hinge element can have a recess for the locking element, through which the locking element can be inserted.

With regard to the spring, it has proven to be advantageous if it rests on the first hinge element on one side and on the locking element on the other side. As a result of the spring, the locking element can be biased in the direction of the locking position relative to the first hinge element. The locking element can have a contact surface that extends perpendicular to the direction of movement, against which the spring can press to pretension the locking element. The spring can apply its compressive force acting in the direction of the locking position via the contact surface.

Furthermore, it has proven to be advantageous if the locking element can be moved into the unlocking position against the force of the spring. The locking element can be retracted against the force of the spring and thus brought into the unlocked position.

For the corresponding movement, it has proven to be advantageous if the locking element has a handling area over which the locking element can be moved by hand from the locking position to the unlocking position. The locking element can therefore be moved by hand against the force of the spring and can also be moved by hand from the unlocked position to the tilt position. The handling area can be arranged in the end area of the locking element opposite the locking contour. The locking element can also be reliably tilted about the guide element or about the tilting axis via the handling area.

According to an advantageous development of the invention, an external actuation is proposed, via which the locking element can be moved back and forth. The locking element can also be operated from the outside of the closing element via the external actuation. The external actuation therefore provides an alternative or additional possibility for moving the locking element and for locking or unlocking the two hinge elements. From a design point of view, the external actuation can be coupled to the locking element via gear components and can move it.

The external actuation can, for example, have a manually movable slide that is directly or indirectly coupled to the locking element and via which the locking element can be moved back and forth in a linear direction. Alternatively, the external actuation can also have a rotatable actuation means, which can be rotated, for example, by hand or using a tool. This rotatable actuating means, which is accessible from the outside of the closing element, can then be connected to the locking element, for example via gear components, so that a rotary movement initiates a linear movement of the locking element. The closing element can have a recess for external actuation, so that the locking element can be actuated not only from the inside of the closing element, but also from the outside of the closing element or can be moved back and forth between the locking position and the unlocking position.

Furthermore, it has proven to be advantageous if the hinge is designed as a hinge lock. When the locking element is in the locking position, the hinge can function as both a hinge and a closure, depending on whether the locking element can be pivoted about the hinge axis or not. If the hinge is designed as a hinge lock, corresponding hinge locks are usually arranged on opposite sides of the closing element, so that the closing element can then be opened either to the left or to the right, depending on which hinges or which locking elements of the hinges are currently unlocked or are locked. If all locking elements are unlocked and are in the unlocking position or in the tilt position, the locking element can be removed from the frame.

It can also be provided that the first hinge element is arranged on the frame and the second hinge element is arranged on the closing element. Even with such a configuration, the hinge elements can be connected to one another in an articulated manner in the manner described above and the closing element can be moved accordingly relative to the frame. If the above explanations referred to a relationship to the frame or to the closing element, this then also applies in reverse for a reversed hinge arrangement.

With regard to the task mentioned at the outset, a locking device with a locking element and a frame is also proposed, the locking element being arranged on the frame in a pivotable manner via a hinge and wherein the hinge is designed in the manner described above. This results in the advantages already described with regard to the hinge.

Advantageously, the hinge elements can each be detachably connected to the closing element or to the frame. For this purpose, the hinge elements can each have corresponding mounting holes, via which they can be releasably connected, in particular via screw or bolt connections, to the closing element or to the frame. The hinges can be arranged such that the hinge axis extends along the closing element. Depending on the size of the closing element, several hinges can be arranged.

Further details and advantages will be explained in more detail below using the attached drawings. Show in it:

• 1 a hinge in an exploded view;
• 2a to 2c a hinge in different positions;
• 3a to 3e a door hinged on a frame in various positions;
• 4a , 4b a sectional top view of two hinge elements, with the locking element in different positions;
• 5a , 5b a door arranged on a frame via a hinge and with external operation.

The representation of the 1 shows a hinge 10 in an exploded view, via which a closing element 30, such as a door, can be articulated to a fixed frame 20, so that the closing element 30 can be pivoted relative to the frame 20 and this can be opened and closed. The closing element 30 and the frame 20 are shown in the illustration 1 not shown. The two hinge elements 1, 2 each have mounting holes 1.2, 2.3, via which they can be detachably connected to the frame 20 or to the closing element 30.

The hinge 10 essentially consists of three elements, namely a first hinge element 1, which is arranged on the closing element 30, a second hinge element 2, which is arranged on the frame 20 and a locking element 3, via which the two hinge elements 1, 2 can be selectively connected can be locked together.

If the two hinge elements 1, 2 are locked together via the locking element 3, they can be rotated or pivoted relative to one another about a hinge axis A. The two hinge elements 1, 2 are then connected to one another in an articulated manner, basically like a commercially available hinge. However, a separation of the two hinge elements 1, 2 from each other or a translational relative movement of the two hinge elements 1, 2 is not possible. Accordingly, the closing element 30 is movable relative to the frame 20 and can be opened and closed, but the closing element 30 is secured to the frame 20 and cannot be easily removed from it.

If the two hinge elements 1, 2 are not locked, they can also be moved translationally relative to one another, so that the two hinge elements 1, 2 can be separated from one another. In this unlocking position E of the hinge 10 or the hinge elements 1, 2, the closing element 30 is no longer secured to the frame 20, but the closing element 30 can be removed from the frame 20.

In order to lock or unlock the two hinge elements 1, 2 accordingly, the locking element 3 can be moved back and forth between a locking position V and an unlocking position E, as will be explained in more detail below.

The 2a until 2c first show different positions of the hinge 10. In the 2a the hinge 10 is in a closed position in which the closing element 30 rests on the frame 20 on the circumference. This position is also in the 3a can be seen, in which the closing element 30 and the frame 20 are also shown. In the 2 B is one relative to the position 2a to recognize the pivoted position. The two hinge elements 1, 2 have been rotated relative to one another about the hinge axis A, but are otherwise still firmly connected to one another. In this position, the closing element 30 was moved relative to the frame 20 and opened slightly. This is also in the representation of the 3b to recognize.

Since both at the 2a as well as at the 2 B Although the hinge elements 1, 2 are connected to one another in an articulated manner, they are also locked to one another, the closing element 30 is arranged in an articulated manner on the frame 20. The locking element 3 is located in the locking position V in both positions.

The 2c now shows a position in which the two hinge elements 1, 2 no longer cooperate not locked to each other, but released from each other. In this respect, the closing element 30 is no longer connected to the frame 20 in this configuration. This is also in the representation of the 3e can be seen in which the closing element 30 was removed from the frame 20.

The functionality of the unlocking and locking of the two hinge elements 1, 2 via the locking element 3 as well as the structural design of the elements will now be explained below, in particular with reference to 1 as well as the 4a and 4b , will be explained in more detail, which show the two separate hinge elements 1, 2 in a sectioned top view.

The frame-side second hinge element 2 has two bearing eyes 2.2 which hold a hinge pin 2.1 in a vertical orientation. For this purpose, the hinge pin 2.1 is clamped in the bearing eyes 2.2 at the upper and lower ends and is then arranged in a stationary manner relative to the frame 20 together with the other components of the second hinge element 2. Between the two bearing eyes 2.2, the first hinge element 1 is articulated to the hinge pin 2.1, so that the first hinge element 1 can be rotated relative to the second hinge element 2 about the hinge pin 2.1 or about the hinge axis A running centrally through the hinge pin 2.1.

The first hinge element 1 is supported on the lower bearing eye 2.2. To reduce friction, the second hinge element 2 is equipped with a washer 6, which is shown in the illustration 1 can be recognized. This washer 6 is arranged on the hinge pin 2.1 and between the lower bearing eye 2.2 and the first hinge element 1. The weight of the closing element 30 can thus be introduced via the first hinge element 1 and via the washer 6, which is then loaded under pressure, into the bearing eye 2.2 and thus into the fixed frame 20.

For the articulated connection of the two hinge elements 1, 2, the first hinge element 1 has a hinge pin receptacle 1.1, which has a U-shaped cross-section and which is therefore adapted to the geometry of the hinge pin 2.1. When the two hinge elements 1, 2 are plugged together, the hinge pin 2.1 lies in the hinge pin receptacle 1.1, as shown in the illustrations 3a to 3c is visible. The hinge pin 2.1 can then be secured in the first hinge element 1 or in the hinge pin receptacle 1.1 via the locking element 3 designed as a latch, so that the two hinge elements 1, 2 are connected to one another in a non-detachable but articulated manner.

The locking element 3 is guided in the first hinge element 1 and can be moved back and forth in a linear direction between the locking position V and the unlocking position E. How this is based on the representation of the 4b can be clearly seen, the locking element 3 is biased into the locking position V via a spring 4 designed as a compression spring. The locking element 3 has a contact surface 3.6 which extends perpendicular to the direction of movement, via which the spring 4 applies its force which biases the locking element 3 into the locking position V.

In order to pull the spring from the locking position V into the unlocking position E against the force of the spring 4, the locking element 3 has a handling area 3.5 at the end, which is shown in the illustrations 4a and 4b can be recognized. The locking element 3 can be retracted by hand via the handling area 3.5. On the side opposite the handling area 3.5, the locking element 3 has a locking contour 3.7. When the locking element 3 is in the locking position V, the locking contour 3.7 secures the hinge pin 2.1 in the first hinge element 1 or in the hinge pin receptacle 1.1 of the first hinge element 1. The hinge pin 2.1 is then encompassed by the hinge pin receptacle 1.1 and by the locking contour 3.7, so that it is secured in a form-fitting manner in the first hinge element 1.

The locking contour 3.7 also has a substantially U-shaped cross section, which, however, is rotated by 90 degrees compared to the cross section of the hinge pin receptacle 1.1, as can be seen, for example, in the enlarged sectional view of 4b is easy to see. Due to this configuration, the hinge pin 2.1 can be reliably gripped and the two hinge elements 1, 2 can be locked together in an articulated manner.

Like this based on the 1 As can be seen, the locking element 3 is not only guided in the first hinge element 1, but a guide element in the form of a guide pin 5 is also provided, which holds the locking element 3 movably in the first hinge element 1. For this purpose, the guide pin 5 is connected in its two end regions to the first hinge element 1 and this extends through the locking element 3. The locking element 3 has a recess in the form of an elongated hole 3.1, in which the guide pin 5 is guided, or over which the locking element 3 relative to the first Hinge element 1 fixed guide pin 5 is guided.

However, the locking element 3 is not only guided in a linear direction by the guide pin 5 and the elongated hole 3.1, but the guide pin 5 and the elongated hole 3.1 also ensure that the locking element 3 only within predetermined limits, i.e. between the locking position V and the unlocking position E , can be moved back and forth linearly. The two ends of the elongated hole 3.1 function as stops 3.2, 3.3, so that the guide pin 5 rests against one of the stops 3.3 in the locking position V and correspondingly against the other stop 3.2 in the unlocking position E.

In addition to the linear movement of the locking element 3 from the locking position V into the unlocking position E, the locking element 3 can also be tilted about a tilting axis P into a tilting position K in the unlocking position E. This tilt position K is shown in the illustration 4a to recognize. The tilt axis K runs through the guide pin 5, which also functions as a pivot point or swivel joint for the locking element 3.

As a rule, closing elements 30 are connected to a frame 20 not just via a single hinge 10, but via several. To dismantle the closing element 30, it is therefore necessary to first move the locking elements 3 of all hinges 10 into the unlocking position E. Although this is not a problem for a single hinge 10 and this can be done by hand in a very simple manner, the locking element 3 is biased into the locking position V by the spring 4. This means that the locking elements 3 would then have to be held by hand in the unlocking position E so that they do not automatically snap back into the locking position V.

In order not to have to hold the locking elements 3 in the unlocking position E, they can be tilted from the unlocking position E into the tilting position K. In the tilting position K, the locking elements 3 cannot move back into the locking position V, so that the hinge pin receptacle 1.1 is instead kept open. Even in the tilt position K, the locking element 3 is therefore in a retracted and unlocking position.

In order to prevent a backward movement of the locking element 3 in the tilting position K, the locking element 3 is locked in the tilting position K with the first hinge element 1. The locking element 3 has a locking recess 3.4, which is shown in the illustration 4a can be recognized. The locking recess 3.4 is designed in the manner of a recessed shoulder and this can reach behind the first hinge element 1 in the tilting position K. The locking element 3 and the first hinge element 1 are then locked together in the tilting position or positively connected to one another in such a way that a linear movement of the locking element 3 in the direction of the locking position V is prevented or prevented.

Due to the compressive force of the spring 4, the locking recess 3.4 is pressed against the first hinge element 1 in such a way that reliable locking is ensured. In order to move the locking element 3 back into the locking position V, the locking must be canceled. According to the presentation of the 4a it is only necessary to move the locking element 3 via the handling area 3.5 from the tilting position K about the tilting axis P back into the unlocking position E. Due to the biasing force of the spring 4, the locking element 3 is then automatically moved into the locking position V.

Locking the two hinge elements 1, 2 is therefore very simple. If a locking element 30 is to be attached to the frame 20, all locking elements 3 are first moved into the unlocking position E and then locked in the tilt position K. If the closing element 30 is positioned such that the hinge bolts 2.1 of the second hinge elements 2 are arranged in the hinge bolt receptacles 1.1 of the first hinge elements 1, it is sufficient to tilt the locking elements 3 slightly in order to release the locking connection. The locking elements 3 then snap shut automatically and lock the two hinge elements 1, 2 together.

In order, among other things, to simplify the separation of the two hinge elements 1, 2 from one another, the locking contour 3.7 is extended on one side. This extension forms a pressure nose 3.71, which is shown in the illustration 4a can be seen and which moves in the direction of the opening of the hinge pin receptacle 1.1 when the locking element 3 tilts. This is in the 4a recognizable. When the locking element 3 is thus moved into the tilt position K, the pressure lug 3.71 presses against the fixed hinge pin 2.1, which results in the entire first hinge element 1 being pushed away from the hinge pin 2.1 and thus also from the second hinge element 2.

Furthermore, the pressure lug 3.71 not only facilitates the separation of the two hinge elements 1, 2 but also simplifies the assembly of the closing element 30. Because when the hinge pin 2.1 is moved into the hinge pin receptacle 1.1 or when the first hinge element 1 is arranged and moved in such a way that the hinge pin 2.1 is moved into the hinge pin receptacle 2.1 and this comes into contact with the pressure lug 3.71, the locking element 3 is thereby tilted about the tilting axis P from the tilting position K into the unlocking position E, in which the locking element 3 then automatically snaps shut. If the hinge pin 2.1 comes into contact with the pressure lug 3.71 and the locking element 3 is tilted as a result, the two hinge elements 1, 2 are automatically locked together. In this respect, the pressure lug 3.71 also simplifies the locking of the two hinge elements 1, 2 or the assembly of the closing element 30 on the frame 20.

The 5a and 5b finally show a further development of the hinge 10, in which the locking element 3 can be moved not only from the inside via the handling area 3.5, but also from the outside via an external actuation 9. The closing element 30 has a recess for the external actuation 9, so that the external actuation 9 is accessible from the outside 30.1 of the closing element 30, and the locking element 3 can be moved from the outside even when the closing element 30 is closed.

In order to move the locking element 3 accordingly, the external actuation 9 can, for example, have a slide, which is shown in the illustration 5a can be seen, or a rotatable actuation that is shown in the illustration 5b is shown. Depending on which form of external actuation is provided, various transmission components can then be provided in order to transmit the corresponding movement to the locking element 3 and to transfer it from the locking position V to the unlocking position E.
