Description

Hinge and system for releasably connecting a door to a frame

The invention relates to a hinge for releasably connecting a door to a frame, comprising: a frame part for fastening to the frame, a door part for fastening to the door, a hinge pin with a pin axis and a

Locking element, the frame part and the door part being displaceable relative to one another along the pin axis between a pivot position and an assembly position, the frame part and the door part being connected to one another in the pivot position in such a way that the frame part and the door part relative to one another around the pin axis between an open Position and a closed position can be pivoted, the locking element being adjustable between a locking position and a release position, the displacement of the frame part and the door part from the pivoting position into the assembly position being positively blocked by the locking element in the locking position and being released in the release position, and wherein the locking element is held on the frame part or on the door part so as to be adjustable from the locking position into the release position and back.

The invention also relates to a system for releasably connecting a door to a frame, comprising: a frame, preferably formed by a sheet metal cabinet, a door, preferably a sheet metal cabinet door, and a hinge.

Hinges are basically used to connect two components to one another so that they can pivot about an axis. A large area of application of hinges is the assembly of doors on the associated frame. For example, house or room doors can be mounted on frames provided for this purpose, or furniture doors on frames formed by corresponding furniture by means of hinges. Hinges are also used in control cabinets to keep the To mount the control cabinet doors on the frame provided by the control cabinets.

Regardless of the type of door and the frame, the door is mounted on the frame in that one or more connections, hereinafter referred to as hinge connections, are established between the door and the frame via one or more hinges. For each hinge connection, a frame part of the hinge is usually first attached to the frame and a door part of the hinge is attached to the door. Subsequently, the frame part and the door part can then be pivotably connected to one another via a hinge pin of the hinge and the hinge connection can thus be established. The door is dismantled from the frame accordingly by releasing the one or more hinge connections existing between the door and the frame. This is usually done by releasing the connection established by the hinge pin between the frame part and the door part. Then, if necessary, the door part can then be detached from the door and / or the frame part from the frame. In practice, hinges have to meet different, sometimes conflicting requirements. The hinges on the one hand are intended to enable the door to be mounted on the frame easily and quickly and the door to be removed from the frame. On the other hand, however, it should also be avoided as far as possible that the connection between the frame part and the door part is inadvertently released, in particular when the door is pivoted, and that the door is accidentally unhooked. Last but not least, the hinges should also enable simple, fast and therefore inexpensive production. The known solutions have so far not met these requirements in one

satisfactory dimensions.

The invention is therefore based on the object of designing and developing the hinge mentioned at the beginning and described in more detail and the system mentioned at the beginning and described in more detail in such a way that with low Manufacturing costs of the hinge a hinge connection can be easily and quickly both established and released and at the same time accidental unhooking of the door is avoided as far as possible.

This object is achieved by a hinge for releasably connecting a door to a frame, comprising: a frame part for fastening to the frame, a door part for fastening to the door, a hinge pin with a pin axis and a locking element, the frame part and the door part being relatively are mutually displaceable along the pin axis between a pivot position and a mounting position, the frame part and the door part are connected to each other in the pivot position such that the frame part and the door part relative to each other around the pin axis between an open position and a

closed position are pivotable, wherein the locking element is adjustable between a locking position and a release position, wherein the displacement of the frame part and the door part from the pivoting position to the assembly position is positively blocked by the locking element in the locking position and released in the release position, and the Locking element is held adjustable from the locking position into the release position and back on the frame part or on the door part.

The hinge according to the invention is suitable for pivotably connecting a door to a frame. For this purpose, the hinge has a frame part and a door part, wherein the hinge can be fastened to the frame with the frame part and to the door with the door part. With regard to a simple and at the same time stable connection of the hinge to the frame and / or to the door, it can be advantageous if the frame part has fastening means for fastening to the frame and / or the door part has fastening means for fastening to the door. For the sake of simplicity, the fastening means can be designed as bores regardless of whether they are provided on the frame part or the door part. Alternatively or additionally, it can be advantageous if the frame part and / or the door part are each made in one piece. This way it won't just be one simple and inexpensive production, but also enables high stability of the frame part and / or the door part. With regard to a high level of stability of the frame part and / or the door part, it can also be advantageous if the frame part and / or the door part are made from a metallic material, in particular from steel or aluminum. Alternatively, it is also possible that the frame part and / or the door part are made of plastic.

In addition to the frame part and the door part, the hinge also includes a

Hinge pin that has a pin axis. The pin axis can preferably be the longitudinal axis of the hinge pin. The longitudinal axis of the hinge pin can in particular be understood to mean the axis of symmetry of the hinge pin, along which the spatial extent of the hinge pin is greatest. Regardless of this, with regard to simple and inexpensive manufacture and high stability of the hinge pin, it can be advantageous if it is designed in one piece. Alternatively or additionally, the hinge pin can be made from a metallic material, in particular steel or aluminum. This can have a positive effect on the stability of the hinge pin. Alternatively, it is also possible that the hinge pin is made of plastic.

The frame part and the door part can be displaced relative to one another between a pivoted position and an assembly position along the pin axis. A displacement along the pen axis can be understood to mean a displacement in a direction whose directional component is parallel to the pen axis

at least as large, preferably at least twice as large, as theirs

Directional component perpendicular to the pen axis. In particular, however, a shifting along the pen axis becomes a shifting in one direction

understood, which is arranged parallel or collinear to the pin axis. In the pivoted position, the frame part and the door part are connected to one another so that they can pivot relative to one another about the pin axis, namely between an open position and a closed position. Take the frame part and the door part in the open position has a different angular position relative to one another than that in the closed position. Thus, the closed position can serve to arrange the door in a closed position relative to the frame, and / or the open position can serve to arrange the door in an open position relative to the frame. Regardless of this, it can be advantageous if the frame part and the door part are pivoted relative to one another in the open position by at least 45 °, preferably at least 70 °, in particular at least 90 °, compared to the closed position. In the assembly position, the connection between the frame part and the door part can be canceled. This enables easy assembly and disassembly of the door. Then the connection between the frame part and the door part can be established simply by moving the frame part and the door part from the mounting position to the pivoting position and can be canceled just as easily by moving the frame part and the door part from the pivoting position to the mounting position.

In order to prevent the frame part and the door part from unintentionally moving from the pivoted position into the assembly position, which may result in the door being unintentionally unhooked, the hinge finally has a locking element. The locking element can be adjusted between a locking position and a release position. The locking element blocks the displacement of the frame part and the door part relative to one another along the pin axis from the pivoting position to the assembly position with a positive fit when the locking element is in the locking position, preferably regardless of which angular position the frame part and the door part assume relative to one another . If, however, the locking element is in the release position, there is

The locking element allows the frame part and the door part to be displaced relative to one another along the pin axis from the pivot position into the assembly position. It is useful if the locking element allows pivoting of the frame part and the door part relative to each other as not impaired. The frame part and the door part are preferably also pivotable in the pivoted position relative to one another about the pin axis between the open and the closed position when the locking element is in the

Locked position and / or in the release position. Regardless of this, it can be advantageous with regard to the stability and service life of the locking element if the locking element is made of a metallic material, in particular steel or aluminum. Alternatively, it is also possible that the locking element is made of plastic.

In order to improve the handling of the locking element and thus enable easier and faster assembly and disassembly of the door, the locking element is held on the frame part or on the door part in such a way that the locking element between the locking position and the

Release position is adjustable. The locking element is preferably held captive on the frame part or the door part. It can thus be prevented that the locking element is accidentally lost, which can also have a positive effect on the handling of the locking element. With regard to the handling of the locking element, it can alternatively or additionally also be advantageous if the locking element is held on the frame part or the door part so as to be displaceable between the locking position and the release position. A particularly good handling of the locking element can, however, be achieved if the locking element between the

Locking position and the release position about a pivot axis

is pivotally held on the frame part. The pivot axis is preferably arranged in such a way that it is arranged at least substantially parallel to the pin axis when the frame part and the door part are in the

Swivel position.

According to one embodiment of the hinge it is provided that the frame part and the door part relative to one another between two different pivot positions for Connecting the door to opposite sides of the frame are adjustable. In this case, the frame part and the door part can be set in a further (second) position relative to one another in addition to the already described (first) pivot position

Take up the swivel position. For example, one of the two

Pivot positions are used to connect the door to the right side of the frame, and the other of the two pivot positions are used to connect the door to the left side of the frame. In this way it is possible that the same hinge can be used to connect the door to different sides of the frame. It is therefore no longer necessary to adapt the hinge type to the frame side to which the door is to be connected. In this way, the number of types of hinge to be produced can be reduced, which enables the production costs to be reduced. It is useful if the frame part and the door part are connected to one another so that they can pivot relative to one another about the pin axis between a closed position and an open position in both pivoted positions.

If two different pivot positions are provided, it can also be advantageous if the frame part and the door part can be displaced relative to one another along the pin axis from the pivot positions into an assembly position and back. In this way it is made possible that the frame part and the door part can be adjusted easily and quickly between the two pivot positions. This applies in particular if the

Connection between the frame part and the door part is canceled. Regardless of this, it can be provided that in both pivot positions the

Moving the frame part and the door part relative to each other along the

The pin axis is positively blocked from the respective pivot position into the associated assembly position by the locking element in the locking position and released in the release position. This way it can work in both

Pivoting positions of the frame part and the door part are avoided that the frame part and the door part inadvertently move from the corresponding pivoting position into the associated assembly position without an additional one Locking element would have to be provided. This applies in particular when, in both pivot positions, the frame part and the door part are moved from the corresponding pivot position into the associated assembly position by the locking element in the locking position, regardless of this

Is positively blocked which angular position the frame part and the door part assume relative to one another.

Another embodiment of the hinge provides that the locking element is positively connected to the hinge pin in the locking position in such a way that the frame part and the door part cannot be displaced, in particular relative to one another along the pin axis, from the pivoted position to the assembly position. When the frame part and the door part are in the pivoted position and the locking element is in the locking position, an action between the locking element and the hinge pin

Positive fit, which allows the frame part and the door part to move relatively

Prevented each other along the pin axis from the pivot position into the assembly position, in particular regardless of which angular position the frame part and the door part assume relative to each other. In this way, it can be prevented in a structurally simple manner that there is an accidental displacement of the frame part and the door part from the pivoted position into the assembly position. At the same time, however, in the release position of the locking element, it can be advantageous if the frame part and the door part can be moved easily from the pivoted position into the assembly position

positive connection between the locking element and the

Hinge pin is canceled in the release position of the locking element.

In the event that the frame part and the door part can assume two different pivot positions, for the reasons mentioned above, it can be advantageous if in each of the pivot positions the locking element is positively connected to the hinge pin in the locking position and, preferably, in each the two pivot positions this positive connection is canceled in the release position of the locking element.

According to a further embodiment of the hinge, the hinge pin has a locking groove. The locking element can then engage positively in the locking groove when the frame part and the door part are in the

Swivel position. In this way, a form fit between the locking element and the hinge pin can be produced in a structurally simple manner. In order to be able to provide the form fit independently of the angular position between the frame part and the door part, it can also be advantageous if the locking groove is designed to run around the hinge pin. Then the locking element can namely preferably independently of the relative

Engage angular position between the frame part and the door part in the locking groove. Regardless of this, the locking element is advantageously arranged in the release position outside the locking groove. It can thus be ensured that the frame part and the door part can be adjusted from the pivoted position to the assembly position without any problems. As an alternative or in addition, in the event that the frame part and the door part are adjustable between two different pivot positions, for the reasons mentioned above, it can also be advantageous if the hinge pin has two correspondingly designed locking grooves. Then the locking element in the locking position can, depending on which of the two pivoting positions the frame part and the door part are in, correspondingly engage in one or the other locking groove.

According to a further embodiment of the invention it can be provided that the frame part has a contact surface for contacting the frame or the door part has a contact surface for contacting the door. The contact surface can then be designed in such a way that the door or the door resting against the contact surface

The frame resting against the contact surface when the frame part and the door part are pivoted from the open position to the closed position Locking element adjusted from the release position into the locking position, in particular pivoted. Then, when the locking element is in the release position, when the frame part and the door part are pivoted from the open position to the closed position, it can be automatically moved into the locking position by contact with the door or the frame. In this way it can be prevented that the locking element inadvertently remains in the release position, for example after the door has been mounted on the frame.

Alternatively or additionally, the contact surface of the frame part or of the door part can also be designed in such a way that the frame or door adjacent to it can be adjusted, in particular pivoted, the

Locking element blocked in a form-fitting manner from the locking position into the release position when the frame part and the door part are in the

closed position. This can prevent the

closed position of the frame part and the door part, the locking element is adjusted from the locking position to the release position. This has the advantage that when the door is closed, it is much more difficult to unhook it, for example by unauthorized persons. Provided two different swivel positions and

Accordingly, two different closed positions are provided, it can be advantageous if the door or the frame adjacent to the contact surface, regardless of which of the two closed positions the frame part and the door part are in, the adjustment of the locking element blocked accordingly.

The locking element inadvertently remaining in the release position, for example after the door has been installed, can alternatively or additionally also be prevented by moving the locking element against the restoring force of a spring means from the release position into the locking position and in the direction of the

Restoring force of the spring means is adjustable from the release position into the locking position. The restoring force of the spring means can cause the The locking element is automatically adjusted into the locking position when the locking element is not held in the release position by an external force, for example by the user.

A further embodiment of the hinge provides that the frame part and the door part are positively connected to one another in the closed position in such a way that the movement of the frame part and the door part, in particular relative to one another along the pin axis, from the pivoted position to the assembly position is positively blocked. So can in the closed position of the frame part and the door part regardless of whether the locking element is in the

Release position or the locking position is located, a form fit between the frame part and the door part acts, which blocks the displacement of the frame part and the door part from the pivoted position into the locked position. When the door part and the frame part are in the closed position, the shifting from the pivoted position to the assembly position can not only be positively blocked by the locking element, but also by the especially direct, form-fitting connection between the frame part and the door part. In this way, in the closed position of the frame part and the door part, unhinging the door is made significantly more difficult, which can offer an advantage in terms of safety. However, in order to ensure that the door can be unhooked without any problems when the door is open, it is useful if the positive connection between the frame part and the door part is canceled in the open position. When the frame part and the door part are in the open position, the movement from the pivoted position to the assembly position is blocked

Form fit between the frame part and the door part is therefore preferably

canceled. Then the move from the pivot position to the

The positive fit between the frame part and the door part blocking the assembly position can be produced in a simple manner by pivoting from the open position into the closed position and canceled by pivoting from the closed position into the open position. If two swivel positions and, accordingly, two closed and open positions are provided, For the reasons mentioned above, it can also be advantageous if the frame part and the door part are correspondingly positively connected to one another in both closed positions and, preferably, the positive connection is canceled in both open positions.

Regardless of whether one or two pivot positions are provided, it is further proposed for this embodiment that the frame part has one

Closure receptacle and the door part has a closure element or that the frame part has a closure element and the door part has a closure receptacle. In this way, in the closed position of the frame part and the door part, the locking element can intervene in the locking receptacle to form the interlocking connection between the frame part and the door part that blocks, in particular, the shifting of the frame part and the door part from the pivoted position to the assembly position. Thus, in a structurally simple manner, the positive fit between the frame part and the door part blocking the displacement of the frame part and the door part from the pivoted position into the assembly position can be produced. In the event that two pivot positions and, accordingly, two closed positions are provided, it can be advantageous for the same reason if the frame part or the door part has two

Has closure recordings. Then, depending on which of the closed positions the frame part and the door part are in, the closure element can correspondingly engage in one or the other closure receptacle. Alternatively, the frame part or the door part can also have two

Have closure elements, so that depending on which of the closed

Positions the frame part and the door part occupy, the locking element can engage in either one or the other locking receptacle accordingly.

According to a further embodiment, the hinge pin has an adjustment surface which is arranged obliquely to the pin axis and which is suitable for the locking element when moving the frame part and the door part from the assembly position into the To adjust the pivot position from the locking position to the release position, in particular to pivot. Thus, the locking element can be adjusted from the locking position into the release position simply by moving the frame part and the door part from the assembly position into the pivot position. This has the advantage that when installing the door the locking element does not first have to be moved into the release position by the user and, if necessary, held there, but that the door can simply be hooked in regardless of the position in which the locking element is located. In this way, the assembly of the door on the frame can be further simplified. It offers itself in terms of a simple adjustment of the

Locking element on when the adjustment surface encloses an angle between 15 ° and 60 °, preferably between 30 ° and 50 °, with the pin axis. Out

For the same reason, it can alternatively or additionally be advantageous if the

Adjustment surface is designed to run around the hinge pin and / or conically. Independently of this, the hinge pin can also have two correspondingly designed adjustment surfaces, in particular if the frame part and the door part can assume two pivoting positions and assembly positions. Then, depending on which of the two assembly positions the frame part and the door part can be adjusted into the associated pivoting position, either the one adjustment surface or the other adjustment surface allows the locking element to be adjusted

Effect the locking position in the release position. This can be implemented in a particularly simple manner in terms of design if the two adjustment surfaces

are assigned to different longitudinal ends of the hinge pin.

According to a further embodiment of the invention it can be provided that the frame part or the door part has a pin receptacle. This allows the

Hinge pin in the pivoted position of the frame part and the door part, in particular in the pivoted position of the frame part and the door part, be received in sections in the pin receptacle. So can be structurally simple and

the pivotability between the frame part and the door part in the pivot position, in particular in the pivot positions, is implemented in a cost-effective manner will. This applies in particular when the pin receptacle is designed as a sleeve at least in sections. Alternatively or additionally, it can be useful if in the pivoted position, in particular in the pivoted positions, the

The hinge pin is held positively in the pin receptacle perpendicular to the pin axis, preferably regardless of which angular position the frame part and the door part assume relative to one another. That way you can

ensure that the connection between the frame part and the door part does not inadvertently come off when pivoting relative to one another.

In relation to the pin receptacle, it is further proposed that it have a recess through which the locking element can partially reach in the locking position. In this way, a compact and stable design of the hinge can be made possible. This applies in particular when the recess is arranged between the two longitudinal ends of the pin receptacle, that is to say is arranged in particular at a distance from the two longitudinal ends. Regardless of this, it can also be advantageous with regard to the compactness and stability of the hinge if, in the pivoted position, in particular in the pivoted positions of the frame part and the door part, the locking element engages in the locking position through the recess in the locking groove of the hinge pin.

According to a further embodiment of the hinge it is provided that the

Locking element from the locking position to the

Release position and back is adjustable. So the hinge can preferably without additional tools by hand between the locking position and the

Release position can be adjusted. In this way, the handling of the

The hinge can be further improved, so that the assembly and disassembly of the door can be carried out more easily and in less time.

Another embodiment of the hinge is finally characterized in that the hinge pin is attached to the frame part or the door part. This has the advantage that the hinge pin through the assembly and disassembly of the door User does not have to be brought into position separately and held there, but can be adjusted and held in a simple manner together with the frame part or the door part. This applies in particular if the hinge pin is fixed in place on the frame part or the door part. For the sake of simplicity, the

The hinge pin and the frame part or the hinge pin and the door part can then also be formed in one piece.

The above-described object is also achieved by a system for releasably connecting a door to a frame, comprising: a frame, a door and a hinge for releasably connecting the door to the frame. The system is characterized in that the hinge is designed according to one of Claims 1 to 13. In such a system, the aforementioned advantages of the hinge are particularly evident. This is especially true if the frame and door belong to a sheet metal cabinet. Then the frame can be formed by the sheet metal cabinet, in particular by the body of the sheet metal cabinet, and the door can be a sheet metal cabinet door.

In the following, the invention is merely a preferred one

Exemplary embodiment illustrated drawing explained in more detail.

A perspective view of the hinge from FIGS. 1A-1D, and FIG

3A-3F: the system according to the invention from FIG. 2 in different ways

Pivoting positions in perspective view. 1A and 1B show a detachable hinge 1 according to the invention

Connecting a door to a frame in a perspective view. The hinge 1 has a frame part 2, a door part 3, a hinge pin 4 and a locking element 5. The locking element 5 is arranged on the frame part 2 and the hinge pin 4 is arranged on the frame part 2. In contrast to what is shown in FIGS. 1A and 1B, the arrangement could also be reversed; the locking element 5 could therefore be arranged on the door part 3 and the hinge pin 4 could be arranged on the frame part 2. The

The locking element 5 is pivotably held on the frame part 2, so that the locking element 5 can be pivoted about a pivot axis relative to the frame part 2. The locking element 5 can be adjusted between a locking position (FIG. 1B) and a release position (FIG. 1A). In contrast, the hinge pin 4 is rigidly connected to the door part 3 in the hinge 1 shown.

The hinge pin 4 has a pin axis A which, in the case of the hinge 1 shown, corresponds to the longitudinal axis of the hinge pin 4. In addition, the hinge pin 4 has at each of its two longitudinal ends a conical adjustment surface 6 which tapers in the direction of the associated longitudinal end of the hinge pin 4. Thus, in the exemplary embodiment shown, which is preferred in this respect, the adjustment surfaces 6 each enclose an angle of approximately 35 ° with the pin axis A. Between the two adjustment surfaces 6, the hinge pin 4 also has two locking grooves 7, which are each formed around the hinge pin 4. The frame part 2 has a pin receptacle 8, which is sleeve-shaped, in particular cylindrical, and serves to receive the hinge pin 4 in itself. The pin receptacle 8 has a recess 9 into which the locking element 5 can engage.

The frame part 2 and the door part 3 can be displaced relative to one another along the pin axis A between a pivot position (FIG. 1B) and an assembly position (FIG. 1A). In the pivoting position (FIG. 1B), the hinge pin 4 of the door part 3 is in the The pin receptacle 8 of the frame part 2 is pushed in, but in the assembly position (FIG. 1A) the hinge pin 4 is arranged outside the pin receptacle 8.

The door part 3 has a contact surface 10 on its outside in the area between the two locking grooves 7, with which the door part 3 can be placed against a door (not shown in FIGS. 1A and 1B). In order to be able to fasten the door part 3 in a simple manner to the door resting against the contact surface 10, the door part 3 also has a fastening element in the form of a bore 11. The door part 3 can for example be screwed to the door via this bore 11.

The frame part 2 also has two bores 11, via which the frame part 2 can be screwed to the frame, for example.

The frame part 2 has a locking receptacle 12 and the door part 3 has a locking element 13. Alternatively, the frame part 2 could be a

The locking element 13 and the door part 3 have a locking receptacle 12.

The locking receptacle 12 and the locking element 13 ensure that in the closed position of the frame part 2 and the door part 3 the

Closure element 13 engages in closure receptacle 12. 1C and 1D also show a hinge 1 according to the invention for releasably connecting a door to a frame in a perspective view. The areas of the hinge 1 already described in conjunction with FIGS. 1A and 1B are provided with corresponding reference symbols in FIGS. 1C and 1D. A difference from the configuration of the hinge 1 shown in FIGS. 1A and 1B is that, in the configuration of the hinge 1 shown in FIGS. 1C and 1D, both the frame part 2 and the door part 3 have been turned over (rotation by 180 °). In this way, it is possible to fasten a door with the hinge 1 both on the left side of a frame and on the right side of a frame. The hinge 1 can be used on both sides in that both the frame part 2 and the door part 3 are constructed with mirror symmetry (that is, they have a plane of symmetry). In particular, the door part 3 has a hinge pin 4 which extends in two opposite directions (along the pin axis A) and the frame part 2 has two matching pin receptacles 8 into which the hinge pin 4 can be inserted from two opposite sides. Fig. 1C shows the hinge 1 in the assembly position and that

Locking element 5 in the release position and FIG. 1D shows the hinge 1 in the pivoted position and the locking element 5 in the locked position. In FIG. 2, a system 14 according to the invention with a frame R, a door T and the hinge 1 from FIGS. 1A-1D is shown in a perspective view. In FIG. 2, too, the areas of the hinge 1 already described in conjunction with FIGS. 1A to 1D are provided with corresponding reference symbols. Both the frame R and the door T are only shown partially. The frame part 2 is screwed to the frame R and the door part 3 is screwed to the door T. The configuration and position of the hinge 1 corresponds approximately to that in FIG. 1B

The situation shown, the hinge 1 is thus shown in the pivoted position and the locking element 5 is shown in the locking position.In the pivoted position shown, the frame part 2 and the door part 3 can be pivoted relative to one another about the pin axis A between an open position and a closed position. ln the also shown

In the locking position, the displacement of the frame part 2 and the door part 3 relative to one another along the pin axis A is blocked by the locking element 5.

3A to 3F show the system 14 according to the invention from FIG. 2 in different pivoting positions in a perspective view. Also in FIGS. 3A to 3F are the areas of the already described in conjunction with FIGS. 1A to 2

Hinge 1 is provided with corresponding reference numerals. In FIGS. 3A to 3F, the hinge 1 is continuously in the pivoted position; the hinge pin 4 of the door part is therefore always pushed into the pin receptacle 8 of the frame part 2.

Fig. 3A shows the hinge 1 in an open position in which the

Locking element 5 is in the release position, so not in the Recess 9 of the pin receptacle 8 engages. This situation can exist, for example, immediately after the door has been “hung in”, that is to say immediately after the hinge pin 4 has been pushed into the pin receptacle 8. FIG. 3B shows the hinge from FIG. 3A in a sectional view. In the sectional view, it can be seen particularly well that the locking element 5 with its

The hook-shaped end does not yet engage in the recess 9 of the pin receptacle 8 and thus also cannot block the locking groove 7 of the hinge pin 4.

Fig. 3C shows the hinge 1 in a closed position, in which the

Locking element 5 is in the locking position, the

The locking element 5 thus engages in the recess 9 of the pin receptacle 8. This situation can exist, for example, after the door T has been locked for the first time. FIG. 3D shows the hinge from FIG. 3C in a sectional view. In the sectional view, it can be seen particularly clearly that the

The locking element 5 engages with its hook-shaped end in the recess 9 of the pin receptacle 8 and thus the locking groove 7 of the hinge pin 4 can be blocked. When pivoting the frame part 2 and the door part 3 from the open position (Fig. 3A, Fig. 3B) into the closed position (Fig. 3C, Fig. 3D), the door T has the locking element 5 from the release position into the

Locking position adjusted. The locking element 5 is therefore automatically pressed into the locking position (“locking position”) when the door T is closed, whereby it can be ruled out that the hinge 1 inadvertently remains in an unlocked position.

FIG. 3E shows (like FIG. 3A) the hinge 1 in an open position in which the locking element 5 (in contrast to FIG. 3A) is in the

The locking position is, the locking element 5 engages in the recess 9 of the pin receptacle 8. This situation can exist, for example, after the door T has been hung and after the hinge 1 has been locked (for example by closing the door T for the first time as described above). 3E thus represents represents the proper operating state. FIG. 3F shows the hinge from FIG. 3E in a sectional view. In the sectional view it is particularly easy to see that the locking element 5 engages with its hook-shaped end in the recess 9 of the pin receptacle 8 and can thus continue to block the locking groove 7 of the hinge pin 4.
