Description

The present invention relates to a hinge lock, comprising a frame assembly having an axis for fastening to a door frame and a rotatable hinge assembly which can be supported on the axis with a door part for fastening the hinge assembly to a door, a pivot part which is mounted on the door part so as to be pivotable about a pivot axis and a displaceable pivot part in the door part mounted carriage, the hinge assembly in a hinge state in which the pivot part is pivoted into the door part, exclusively rotatable about the axis of the frame assembly and in a vented state in which the pivot part is pivoted out of the door part, transversely to the Axis of the frame assembly is translationally displaceable and not yet completely detachable from the axis of the frame assembly, and the hinge assembly can be converted from the vented state into a removal state by manually actuating the slide against a spring preload t in which the hinge assembly is completely removable from the frame assembly.

Such hinge locks are used in cabinets, the interior of which can be under pressure. In order to prevent the door from inadvertently pivoting open when a lock is opened due to the pressure present, the overpressure in the cabinet must first be reduced by venting. For this purpose, it is known that the hinge can be brought into a state in which the part connected to the door the hinge can be offset by a predetermined distance relative to the frame of the cabinet.

A hinge lock with the features mentioned at the beginning is off WO 2012/123776 A1 known. In this hinge lock, the pivot part and the door part form a seat for the axis of the frame assembly in the hinge state. The door part and the pivot part are thus designed so that the hinge assembly cannot be displaced transversely to the axis of the frame assembly when the pivot part is pivoted into the door part. The sections of the pivoting part and the door part that form the seat are designed in such a way that the entire hinge assembly can be displaced transversely to the axis when the pivoting part is pivoted sufficiently far out of the door part. For this purpose, the pivot axis of the pivot part mounted in the door part must coincide with the axis of the frame assembly.

In the known hinge lock, the spring-loaded slide is designed and arranged so that when the pivot part is swung out, the hinge assembly can only be displaced transversely to the axis of the frame assembly until it comes into contact with the axis of the frame assembly with the slide. So that the hinge assembly can be completely removed from the axis of the frame assembly, the slide must be withdrawn against the spring bias so that the retracted slide with the hinge lock can be moved past the axis of the frame assembly.

In the case of the aforementioned hinge lock, the slide is arranged asymmetrically in the door part, which means that in the vented state the force is introduced unevenly into the hinge assembly, which in turn could lead to uneven wear.

The object of the present invention is therefore to solve the problems described with reference to the prior art and, in particular, to provide a hinge assembly which is evenly loaded in the vented state.

This object is achieved by a hinge lock with the features of the independent claim. Advantageous further developments of the hinge lock are specified in the dependent claims and in the description, with individual features of the advantageous further developments being able to be combined with one another in a technologically sensible manner.

This object is achieved in particular by a hinge lock with the features mentioned at the beginning, the slide being designed and arranged in such a way that the slide together with the door part forms a seat for the axis of the frame assembly in the hinge state and that the pivot part is designed and arranged in such a way that the pivot axis of the pivoting part is also offset in the hinge state to the axis of the frame assembly, the pivoting part acting on the slide during pivoting out of the door part and shifting it until the ventilation state is reached and the slide is manually shifted further against the spring preload to reach the removal state got to.

The basic idea of the invention thus provides that the slide, in particular at one end, forms part of the seat for the axis of the frame assembly, which surrounds the axis of the frame assembly, so that the hinge assembly can be rotated around the axis of the frame assembly in the hinge state. In order to release the seat for the axis, the slide is first displaced by the pivoted part so far that the hinge assembly can be moved to the frame assembly without the hinge assembly being completely detachable from the frame assembly. The end of the slide is shaped in such a way that after the offset the hinge assembly again comes into contact with the axis of the frame assembly. The coupling between the pivoting part and the slide is thus designed in such a way that the slide is only displaced over a partial section of its displacement path in the vented state. In order to achieve the acceptance status, the slide must be moved further manually until the axis of the frame assembly is completely released. In this way, the slide can be arranged centrally in the door part, so that the forces are introduced evenly into the hinge assembly in the vented state.

At its end facing the frame assembly, the carriage has on the one hand a section that is in contact with the axis of the frame assembly in the hinge state, and on the other hand an area that is only transverse to the axis of the frame assembly with the in the venting position after the hinge assembly has been attached Axis comes into contact.

The offset of the pivot axis of the pivot part of the hinge assembly to the axis of the frame assembly ensures that the (virtual) pivot axis of the pivot part does not coincide in any state with the axis of rotation of the hinge assembly formed by the axis of the frame assembly. In the hinge state, the pivot axis of the pivot part is offset, in particular, parallel to the axis of the frame assembly. The hinge assembly is also designed so that a pivoting of the pivoting part results in a displacement of the slide, regardless of whether the pivoting part is pivoted in or out.

In a preferred embodiment of the hinge lock, the slide has a first actuation projection which interacts with the pivoting part, so that the pivoting part moves the slide without spring preload when pivoting. The slide is therefore mounted without spring preload over the displacement path between the hinge state and the ventilation state. The sliding of the carriage results between them both states therefore solely due to the pivoting of the pivoting part, which cooperates with the first actuating projection.

In order to transfer the slide from the venting state to the removal state, a second actuating projection is provided in particular, with which the slide can be actuated manually against a spring preload. Without manual actuation, the slide always returns to the vented state due to the spring preload.

So that the hinge assembly can be placed on the axis of the frame assembly again without manual independent actuation of the slide, the slide is beveled at its end facing the frame assembly on its underside, so that the slide when the hinge assembly in the ventilation state is placed on the frame assembly through the axis against the spring tension is shifted out of the vented state. To put it back on the axis, the pivoting part must therefore be pivoted out of the door part of the hinge assembly. The bevel of the slide ensures that the slide is pushed back by the force applied when it touches down. After the slide has been moved past the axis of the frame assembly, it is pushed back into the ventilated state due to the spring preload, so that the hinge assembly is fastened to the frame assembly. The pivoting part then has to be pivoted into the door part so that the hinge assembly is brought into the hinge state.

In the case of the hinge lock known from the prior art, it is also disadvantageous that the distance between the axis of the frame assembly and the door frame can only be changed by placing washers. However, it regularly happens that due to the installation situation specified, for example, by the geometry of the frame or the thickness of the seal the position of the axis has to be adjusted. It would therefore be desirable to be able to adjust the distance from axis to frame more easily during assembly. This problem is also solved independently of the solution described above in that the frame assembly comprises a frame part for fastening the frame assembly to the door frame and a door part forming the axis, which are connected to one another via at least one adjusting means so that a distance of the axis to the Door frame is adjustable by means of the at least one adjustment means. The object described above is thus achieved in that the frame assembly consists of at least two elements which can be fixed in different positions relative to one another with the adjustment means.

In this context it is provided in particular that the at least one adjustment means is a screw which is passed through a through hole in the frame part and engages in a thread formed in the axle part.

In one embodiment it is provided that the screw is arranged with its screw head having a height in a recess formed on the side of the frame part facing the hinge assembly and that the through hole is an elongated hole. With such an arrangement, the distance between the axis and the frame can be adjusted by tightening the screw at different heights on the elongated hole.

Alternatively, it can be provided in particular that the screw is inserted from the top into the frame assembly and screwed into a nut on the underside of the frame part, which is positively arranged in a recess on the underside of the frame part and whose height corresponds to the depth of the recess. The distance between the axis and the frame can thus be easily changed since the screw is easily accessible.

When mounting on a cabinet, the frame assembly 2 is attached to a frame of the cabinet and the door part 5 of the hinge assembly 4 is attached to a door of the cabinet. In the in Fig. 1 and Fig. 6 In the illustrated hinge state, the hinge assembly 4 connected to the door would be pivotable about an axis 3 formed by the frame assembly 2.

If the pivoting part 6 is pivoted out of the door part 5, the hinge assembly 4 is in a vented state ( Fig. 7 ), in which the hinge assembly 4 can be displaced transversely to the axis 3 of the frame assembly 2, the hinge assembly 4 not yet being completely removable from the frame assembly 2. In order for the door connected to the hinge assembly 4 to be completely detachable from the frame, a slide is still required 8 must be pulled completely backwards so that the axis 3 of the frame assembly 2 is completely released ( Fig. 8 ).

In Fig. 2 the components of the hinge assembly 4 are shown. The pivot part 6 is mounted pivotably in the door part 5 by means of a pivot axis 7. The pivot axis 7 is offset relative to a seat surrounding the axis 3 of the frame assembly 2. The pivot part 6 can be fixed in a state pivoted into the door part 5 by means of a lock 25.

The hinge assembly 4 further comprises a slide 8 which is slidably mounted in the door part 5. The carriage 8 comprises an end 11 facing the frame assembly 2, a first actuation projection 9 and a second actuation projection 10. With its end 11, the carriage 8 in the hinge state forms part of the seat for the axis 3 of the frame assembly 2 ( Fig. 6 ). The slide 8 is coupled to the pivoting part 6 via the first actuation projection 9 in such a way that the slide 8 is withdrawn from the pivoting state into the ventilation state while the pivoting part 6 is pivoted out of the door part 5 so that the seat for the axis 3 is partially released becomes. In the ventilated state, the hinge assembly 4 can only be displaced transversely to the axis 3 of the frame assembly 2 until the outermost end of the carriage 8 comes into contact with the axis 3 ( Fig. 7 ). In order to transfer the hinge assembly 2 into a removal state, the slide 8 must be pushed back completely by means of the second actuating projection 10 against a preload provided by a spring 24, whereby the axis 3 of the frame assembly 2 is completely released ( Fig. 8 ).

In the Figures 3 and 4 a first embodiment of a frame assembly 2 is shown. The frame assembly 2 comprises a frame part 12 and an axle part 13. The frame part 12 and the axle part 13 are by means of two Screws 14 connected to one another, which are guided from an upper side 22 first through a through hole 15 in the axle part 13 and then through a through hole 15 in the frame part 12. In the following, the screws 14 are each screwed into a thread 16 in the axle part 13 and then pass through a through hole 15 in the frame part 12. On an underside 26, not visible recesses are formed here, in each of which a nut 23 is arranged, in which the Engage screws 14. The distance between the axis 3 and a frame can thus be adjusted by operating the screws 14.

In Fig. 5 a further embodiment of the frame assembly 2 is shown. In this embodiment, the through hole 15 is designed as an elongated hole in one side 21 of the frame part 12 which faces the hinge assembly 4 in the assembled state. The through hole 15 is designed as an elongated hole, so that the distance between the axis 3 and the frame can be determined by the relative position of the screws 14 engaging in the thread 16 formed on the axis part 13. The screws 14 each have a screw head 17 with a height 18. The screw heads 17 are each arranged in a countersunk hole described as a recess 19, the depth 20 of which is at least as great as the height 18 of the screw heads 17.
