Abstract

The proposed cup hinge comprises a sole plate (1) for attachment to a furniture unit (7). The sole plate comprises a base plate (10) and a covering plate (11) and contains a horizontal slide (5) which is continuously adjustable in a direction perpendicular to the leading edge (2) of the furniture unit (7). The horizontal slide (5) enables a hinge arm (63, 86), connected via two articulated levers (80, 81) to a cup element (78), to be brought into position. This is done preferably with the assistance of a ratchet device (9, 40) which is acted on by a spring . The hinge arm contains an adapter unit (53, 87) which forms the actual connection with the horizontal slide (5). The hinge arm (63, 86) can be adjusted in relation to the adapter unit (53, 87) while remaining parallel to it.

Description

Description:

Concealed hinge

The invention is based on a pot hinge. Pot hinges are used to attach doors or flaps to furniture. They contain a base plate that is attached to the furniture body, and a pot element that is articulated to the base plate via a hinge arm and that is connected to the door or flap.

An example of such a concealed hinge is known from DE-PS 28 06 958.

Pot hinges of this type have several adjustment options. One adjustment option is to change the position of the axes of rotation further forwards or backwards in relation to the front edge of the cabinet body, to compensate for inaccuracies in the attachment of the hinges.

Another adjustment option is to adjust the hinge up or down.

A third adjustment option is the so-called support adjustment, in which the hinge is to be adjusted perpendicular to the fastening surface of the base plate.

In a known solution of this type (EP-Bl-168 731), in order to adjust the hinge in this direction, the hinge arm is pivoted about a pivot axis arranged at its end remote from the door. With this pivoting, however, the gap between the door and the front edge of the cabinet body changes. In order to compensate for this, the hinge arm is simultaneously displaced longitudinally in its own longitudinal direction when pivoting. The object of the invention is to create a concealed hinge which, with a simple structure, has a very simple and safe adjustment possibility perpendicular to the fastening plate of the base plate.

To achieve this object, the invention proposes a concealed hinge with the features of claim 1. Further developments of the invention are the subject of the dependent claims.

In particular, it can be provided that the parallelism between the hinge arm and the adapter element is maintained during the adjustment. While in the prior art the gap compensation is possible due to the simultaneous pivoting and longitudinal displacement, the geometry is also retained in the invention. The pivoting in the prior art leads to the fact that the angle between the body wall and the door changes in the closed state, while it remains the same according to the invention. However, the angle is important, particularly when spring mechanisms are present which are intended to keep the door closed.

In a further development of the invention it can be provided that the base plate is constructed from a base plate fastened to the furniture body and a cover plate held on the base plate, which can be adjusted in a direction parallel to the front edge of the furniture body. An adjustment in the vertical direction can thus also be carried out, in the normal case in height.

The hinge according to the invention thus enables adjustment in three directions. It is particularly favorable if the adjustability is infinitely variable. To adjust the two plates that together form the base plate, a toothed pin can be provided according to the invention, which is rotatably mounted in one plate and engages with its teeth in a row of teeth arranged on the other plate. The adjustment can then be effected very simply and precisely with the aid of a tool, for example a commercially available screwdriver.

The guidance between the two plates can take place in that one of the plates, preferably the base plate, rests with its edge edges on the bent edges of the other plate, preferably the cover plate. No undercuts or other additional devices are therefore required for the guidance.

To protect against lifting off, it can be provided that the cover plate has tabs on the bent edges, which are bent after attachment of the base plate to the cover plate and engage under the base plate.

To securely lock the set relative position between the base plate and cover plate, it can be provided that a screw with a pointed conical front end is inserted in a threaded opening of the cover plate, which acts upon an element of the base plate or the cover plate radially outward when screwed in, so that this element counteracts another element of the other plate is pressed. If the screw acts on an element of the cover plate, this type of locking has the advantage that no forces that change the setting occur when the screw is tightened.

In a further development of the invention, it can advantageously be provided that the horizontal slide can also be moved continuously is held on the base plate. Once a position has been set, it can be locked in a manner similar to that between the base and cover plates.

For guiding and holding the horizontal slide on the

Base plate can be provided that it has at least one extension which extends through a longitudinal slot in the base plate. To fix it can be provided in particular that the approach has a widened head with which it can hold on the back of the base plate laterally behind the edges of the longitudinal slot. According to the invention it can be provided that two such approaches are provided at a distance in the longitudinal direction of the horizontal slide.

According to the invention, in a further development it can be provided that a screw is provided for locking the horizontal slide on the base plate, which tries to lift it off the base plate and thereby allows the hooks of the lugs to come into contact with the underside of the base plate.

This screw can advantageously be inserted into a threaded opening of the horizontal slide and act on the top of the base plate. The locking then also takes place with the aid of a tool in the usual direction of rotation. It would of course also be possible to insert the locking screw into a threaded opening in the base plate and then to lock it by turning it to the left. In this case, the horizontal slide would have an opening that is narrower than the diameter of the screw.

For particularly secure locking, it can be provided according to the invention that the free end of the locking screw, ie the end which effects the locking by being acted upon, is designed as an annular cutting edge. The fastening device for fastening the hinge arm to the horizontal slide can be designed according to the invention in such a way that the fastening takes place without tools by simply pressing on or snapping on. For this purpose, the fastening device can have at least one spring-loaded pawl which engages in a corresponding recess in the hinge arm.

In order to also be able to undo the fastening device without tools, the fastening device according to the invention can have an actuating element for opening or retracting the pawl.

It is possible, for example, to hang the hinge arm in one place and then to bring it into engagement with the spring-loaded pawl. According to the invention, however, it can be provided in a particularly favorable manner that the attachment can be carried out by simply sliding it open. This can be pushed on perpendicular to the body. Especially in the case of doors with several hinges, attachment is greatly facilitated in this way, since all hinge arms can be pressed and snapped onto the parts of the hinge fastened to the body wall at the same time perpendicular to the body wall.

For this purpose it can be provided that pawls are arranged on both sides of a center line and at two points spaced apart in the direction of displacement of the horizontal slide. Then it becomes possible to hold the hinge arm in four places with the help of spring-loaded pawls.

The invention proposes that the pawls are made such that they themselves have spring properties. In particular ders advantageous further development can be provided that the pawls and the spring are integrally formed from a correspondingly bent spring wire.

According to the invention, in a further development of the invention

Fastening device can be designed such that it acts on the hinge arm in the direction of its removal, for example by a spring, preferably by the same spring which also acts on the pawls. This leads to the fact that when the fastening device is loosened, preferably with the aid of the actuating element, the hinge arm is released from the fastening position. At the same time, this spring action also leads to a certain counterpressure being generated when the hinge arm is attached, which leads to a tangible snapping of the hinge arm.

According to the invention, it can be provided that the actuating element acts pullingly on the spring, so that the operations mentioned can be triggered by a simple pulling operation.

For example, the pawls can be formed by projections which engage through window-like openings in two opposite side walls of the horizontal slide in corresponding openings of the adapter element. These window-like openings can simultaneously serve to fix the spring forming the pawls.

The adjustment of the adapter element on the hinge arm can, as proposed by the invention, be carried out in a stepless manner and is preferably effected by means of a screw. Any means can be provided for the parallel displacement. However, it is particularly favorable if two compression springs are supported between the adapter element and the hinge arm, which bring about the parallel alignment of the two parts to one another. In this case, the adjustment can be carried out with the aid of a single adjustment element. In addition, the provision of these compression springs has the advantage that the hinge according to the invention even has a shock-absorbing effect.

To produce the parallel displacement, it can also be provided that a slide is slidably mounted on the adapter element or the hinge arm, which engages in a link guide of the other part. The slide can, for example, have teeth, so that it can then be adjusted by a toothed pin. This toothed pin can in turn be operated with a commercially available screwdriver.

According to the invention it can also be provided that two such sliders are provided at two spaced locations. These slides can be adjusted, for example, by the same adjustment element. In particular, it can be seen that both slides are actuated in opposite directions.

Further features, details and advantages emerge from the patent claims, the wording of which is made by reference to the content of the description, the following description of a preferred embodiment of the invention and with reference to the drawing. Here show:

FIG. 22 shows a representation corresponding to FIG. 17 in a modified embodiment;

FIG. 23 shows a side view of the arrangement according to FIG. 22;

24 shows a representation of a further embodiment corresponding to FIG. 3. The base plate 1 seen in a top view in FIG. 1 is drawn in the correct position, the dash-dotted line 2 is intended to represent the front edge of the furniture body, which therefore runs perpendicularly. The base plate 1 has two wing parts 3, which are arranged at the upper and lower ends of the base plate 1. Between the two wing parts 3 there is a depression 4, which runs perpendicular to the front edge 2. In the recess 4, a horizontal slide 5 is fastened to the base plate 1 and fixed in a certain position with a locking screw 6.

The base plate 1 is fastened to the furniture body 7 with the aid of two screws 8, the screw heads of which can be seen in FIG. 1 through corresponding openings in the base plate 1. A screw 8 is arranged in each wing part 3.

After the locking screw 6 has been loosened, the horizontal slide 5 can be displaced or adjusted somewhat in its own longitudinal direction, so that its distance from the front edge 2 of the body 7 can be adjusted. In a similar manner, the position of the horizontal slide can be changed together with a part of the base plate 1 parallel to the front edge 2.

The horizontal slide 5 contains a fastening device shown in FIG. 1 in the release position, which can be actuated with the aid of an actuating element 9. The actuating element 9 can, for example, as shown, be a push button.

As shown in FIG. 2, the base plate 1 is made up of two plates, namely a base plate 10 and a cover plate 11. In FIG. 2, the base plate 1 is shown in a position rotated about the line IV-IV in FIG. 1. The base plate 10 is screwed onto the furniture body 7 using the screws 8 mentioned, for which purpose it has two fastening holes 12. The base plate 10 has an outer circumference in the form of a rectangle. The cover plate 11 is bent down along its entire edge, ie in the direction of the furniture body 7 or in the direction of the base plate 10. This bent edge 13 has the shape of a rectangle in the area of the wing parts 3. The transverse dimension of the rectangular shape of the base plate 10 corresponds to the inner distance of the bent edge 13 of the cover plate 11, so that the base plate 10 rests on the edge 13 with parts of its longitudinal side edges. As a result, the cover plate 11 is guided on the base plate 10 without any undercuts being necessary for this.

To secure against lifting off, the base plate 10 has raised areas 14, see also FIG. 3, which are formed by folding the base plate 10. Here, the base plate 10 is at a distance from its underside. The edge 13 of the cover plate 11 contains tabs 15 which are bent away laterally inwards and engage under the raised areas 14 of the base plate 10. This secures against lifting.

The base plate 10 contains an elongated opening 16 running approximately parallel to the front edge 2 of the furniture body 7, one longitudinal side edge 17 of which is provided with a row of teeth 18. The teeth of a toothed pin 19 engage in the toothing of this row of teeth 18, which is mounted in the cover plate 11 and is accessible from the top of the cover plate 3 through an opening. The toothed bolt 19 can, for example, have a slot-like shape in its accessible end face Have notch 20 so that it can be turned with a conventional flat-head screwdriver.

As can be seen from FIG. 1, the cover plate 11 contains a punched-out area 21 in which the sheet metal material of the cover plate 11 is deformed downwards to form a curved web 22.

The base plate 10 also contains a punched-out portion 23 which is elongated and rectangular and whose longitudinal direction runs parallel to the adjustment direction of the base plate and cover plate. There, on the base plate 10, a narrow strip 24 is formed, which is directed upward toward the cover plate 11, see FIG. 3 and is positioned such that it lies against the side edge of the web 22.

At the same location in the longitudinal direction of the base plate 10 as the punched-out portion 23, the edge 25 of the base plate 10 is also bent upwards and there forms a second strip 26 corresponding to the strip 24. This strip 26 lies against the bent edge 13 of the cover plate 11.

The cover plate 11 contains a threaded opening 27 into which a threaded screw 28 is screwed. The threaded screw 28 has, at its front end protruding into the bore, a truncated cone-shaped flattening 29 which bears against the inside of the strips 24 and 26. If the threaded screw 28 is screwed in further, it acts on the two strips 24, 26 in the radial direction and presses them outward, so that one strip 24 ver¬ against the web 22 and the second strip 26 against the inside of the edge 13 of the cover plate 11 gets stuck.

For the adjustment of the cover plate 11 on the base plate 10 screwed to the body 7, the toothed pin 19 is used. while the locking screw 28 is used to lock a once set position. In this way, a very precise and sensitive adjustment of the cover plate 11 is possible, and the locking can then be effected in such a way that there is no more adjustment.

In the middle part of the cover plate 11, in which it has the upper recess, the aforementioned bent edge 13 is also formed. As a result, a space is formed in the middle transverse part 30 of the cover plate in which there is a distance from the furniture body 7.

In this central part 30 two longitudinal slots 31 are formed at a distance in a direction running transversely to the front edge 2 of the furniture body 7 and have a widening 32 at one end thereof. By widening 32 hook-shaped lugs 33 of the horizontal slide are inserted, which are then secured behind the edges of the longitudinal slots 32 against lifting off.

FIG. 4 shows another illustration of the parts of the base plate and the horizontal slide in an exploded state for better illustration. The base plate 10 is connected directly to the body 7 after it has previously been connected to the cover plate 11. The horizontal slide 5 is placed on the cover plate 11 and its lugs 33 are inserted through the widened parts 32 of the longitudinal slots 31.

The horizontal slide 5 has a plate-shaped central part 34 which is provided with short, downwardly directed side walls 35 in the region of the long sides. In the middle part 34 there is an apron-like, threaded opening 36 into which a locking screw 37 is inserted. can be screwed. Since the lugs 33 secure the horizontal slide 35 against lifting, screwing the locking screw 37 tightly results in the horizontal slide 5 being acted on away from the cover plate 11, so that the locking and jamming takes place on the underside of the cover plate 11.

In the side walls 35 of the horizontal slide 5, a window-like opening 38 is arranged in the area of both ends, one end 39 of which extends obliquely. A fastening device 39 is inserted between the cover plate 11 and the horizontal slide 5, which in the example shown is designed as a one-piece spring 40. This spring 40 is fixed by projections in the windows 38. A part of the spring 40 is designed as a projection 41, which projects through an opening 42 in the central plate-shaped part 34 of the horizontal slide 5.

FIG. 5 shows a top view of the base plate 10, which could be seen from below in FIG. 2. The raised areas 14, under which the tabs 15 can engage, can be seen in the edge area on the longitudinal side edges. Also visible are the strip 24 formed by the punched-out 23 and the strip 26 formed by the bending of the edge 25, which form a channel with parallel side walls between them for receiving the front part 29 of the locking screw 28.

6 shows the underside of the cover plate 11 with the openings for the fastening screws 8, the opening 43 for mounting the upper end of the toothed bolt 19 and the threaded opening 27 for the locking screw 28. The web 22 can also be seen , which is arranged next to the aforementioned threaded opening 27 for the locking screw 28. This web 22 can also be seen in the angled longitudinal section of FIG. 7. The section of FIG. 7 also shows the tabs 15 in the edge 13 which serve to fix the cover plate 11 on the base plate 10. The recess 4, which forms the central part 30 of the cover plate 11, serves in its recessed area to accommodate the horizontal slide 5, not shown in FIG. 7.

FIG. 9 shows the horizontal slide 5 in a view from below. Its two side walls 5 arranged on the longitudinal side edges each contain a notch 44 in their two end regions, the meaning of which will be explained in the following. The approaches 33 mentioned are produced by bending the punched-out ends of the sheet material of the horizontal slide 5. They have the shape shown in FIG. 10, namely approximately a T-shape with a shaft 45 and a transverse beam 46. The dimension of the transverse beam 46 is selected such that the projections 33 extend through the widened parts 32 of the longitudinal slots Allow 31 to be inserted and then after shifting it can rest behind the edges of the longitudinal slots 31. Accordingly, the width of the shaft 45 corresponds to the width of the longitudinal slots 31.

11 shows a top view of the spring 40 already mentioned in FIG. 4. The spring 40 is produced from a single piece of wire by appropriate bending. Roughly speaking, it has the shape of a U, the ends 47 of the legs 48 being bent toward one another inwards. The legs 48 run essentially parallel to one another. They are each provided with a sawtooth-shaped, outwardly directed pawl 49 at two spaced locations. The pawls 49 have a sloping front edge 50 and a steep trailing edge 51. All leading edges 50 are oriented in the same direction.

At the closed part of the U-shape, the spring 40 deviates from this shape, so that the shape of a W can be seen here. This inwardly directed, again U-shaped part 52 allows not only the better inward springing of the legs 48 of the spring 40, but also forms a projection 41 somewhat protruding from the plane of the spring 40, see FIG. 4. This projection 41 reaches through the opening 42, see FIG. 9 lying above FIG. 11.

The spring 40 of FIG. 11 is compressed and inserted into the horizontal slide 5, the pawls 49 then engaging in the window-like openings 38 in the side walls 35, see FIG. 4. The situation arises as shown in FIG. 5. Here the legs 48 of the spring 40 lie parallel on the inner sides of the side walls 35, while the pawl-like projections 49 reach through the windows 38 and protrude outwards. If one pulls on the actuating element 9 shown on the left in FIG. 15, which is connected to the bent ends 47 of the spring 40, the pawls 49 slide out of the window 38 along their oblique front flanks 50 until the pawls 49 do not protrude more from the outside. This is the opening or unlocking position.

The adapter element 53 to be held in the hinge arm and shown in FIGS. 12 to 14, which will now be described, is intended for connection to the horizontal slide 5.

The adapter element has an elongated central plate 54, which corresponds approximately in shape and dimension to the central part 34 of the horizontal slide 5. On both longitudinal side edges 55 are formed, which are produced by bending the sheet material. Plate elements 56 are formed at the two ends of the side walls 55 and extend up and down over the plate 54. These plate elements 56 arranged at the four corners serve to guide the adapter element 53 in the trough-shaped hinge arm.

In the two side walls 55 there are recesses 57 which correspond in size and position to the windows 38 of the side walls 35 of the horizontal slide 5.

The side walls 55 of the adapter element 53 also have two projections 58 on each of their longitudinal edges, which, see FIG. 13, have ends that are bent toward one another. The size and positioning of these projections 58 is matched to the size and position of the notches 44 in the side walls 35 of the horizontal slide 5. The adapter element 53 can be pushed onto the horizontal slide 5 in such a way that the projections 58 come to lie in the notches 44. As a result, the position of the adapter element 53 with respect to the horizontal slide 5 is fixed.

The plate 54 contains in its center an upward passage 59 with an internal thread 60.

In the longitudinal direction of the adapter element 53 on both sides of the passage 59, upwardly directed webs 62 are formed by punched-out portions 61, the meaning of which will be explained below. As the top view in FIG. 14 shows, the adapter element 53 is elongated with a rectangular outline. The plate 54 contains openings in order to allow access to the underlying horizontal slides 5. If the adapter element 53 is placed on the horizontal slide 5 in the manner described and the spring 40 is released from its release position, the pawls 49 of the spring 40 reach through the windows 38 into the recesses 57 and in this way lock it Adapter element 53 on the horizontal slide, which in turn is fixed on the base plate 1.

The attachment of the adapter element 53 to the hinge arm 63 will be explained with reference to FIG. 17.

16 now shows the hinge arm in a longitudinal section. The hinge arm 63 contains two parallel, approximately right-angled side walls 64 which have two bearing openings 65 for articulated axes in their end region on the right in FIG. 16.

The two side walls 64 are connected to one another by a front wall 66, which has an apron-like, bent downward at its end facing away from the bearing openings 65

Has edge 67. An edge 68 bent downward is also formed in the front region, the distance between these two bent edges corresponding approximately to the longitudinal dimension of the adapter element 53.

The front wall 66 contains a central hole 69 which serves to receive an adjusting screw to be described later. In the longitudinal direction, on both sides of the hole 69, further openings 70, 71 are formed, the edge of which is deformed in such a way that an indentation 72 which is groove-like at least on one side is formed on the underside around the openings 70, 71. This deformation or groove 72 forms a centering for a helical spring 73 designed as a compression spring, which is shown in FIG. 17. In the hinge arm 63, the adapter element 53 is inserted between its side walls 64 and the pulled-down edges 67, 68 and secured by an adjusting screw 74. The two helical compression springs 73 are inserted between the adapter element 53 and the hinge arm 63 and are secured in their position by the edge of the openings 70, 71 on one side and by the webs 62 on the side of the adapter element 53. The characteristics of both helical compression springs 73 are selected identically, so that they act uniformly on the adapter element 53 and thereby hold them parallel to the front wall 66 of the hinge arm 63. The adjusting screw 74 engages with its threaded section 75 in the thread 60 of the passage 59 and rests with the underside of its head on the edge of the hole 69. The distance between the hinge arm and the adapter element 53 is changed by simply adjusting the adjusting screw 74. This change in the distance takes place parallel to itself, in the illustrated and preferred example perpendicular to the surface 76 of the furniture body 7 shown in dash-dotted lines. When adjusted in this direction, the gap distance between the front edge 2 of the body and that used in the door 77 changes Pot element 78 does not.

An axis 79 is inserted into the bearing bores 65, see FIG. 17. An articulated lever 80, 81 can be pivoted about each axis and, in the area of its opposite ends, is in turn connected to articulated axes 82, 83 of the top element 78. The pot element 78 is fastened in the usual way in the door 77, so that this part is not described further.

A tongue spring 84 is held in the hinge arm and, with its free end 85, presses on the articulated lever 80 in the region of its end on the hinge arm side. This end of the Steering lever 80 is shaped such that its distance from the free end 85 of the spring 84 increases when it is opened, while occupying a minimum in the closed position. As a result, the door 77 normally remains closed. Since there is no change in the angle between the hinge arm and the cup element when the hinge arm is adjusted relative to the base plate, the so-called support adjustment, the spring characteristic of this closing spring 84 remains independent of the position of the hinge arm 63 relative to the body 7.

18 shows, in a position corresponding to FIG. 17, a further possibility of how a parallel displacement between a hinge arm 86 and an adapter element 87 can take place. The hinge arm contains two slots 88 in its side walls 64, which run obliquely to the front side 66. Both slots 88 are oriented in mirror image to one another, that is to say they have the same slope but the opposite orientation.

There are two on the plate part 54 of the adapter element 87

Slider 89 slidably mounted, one side of which rests directly on the top of the plate 64 and is secured against lifting off by side extensions 90 of the plate 54. A toothed bolt 92 is inserted through a recessed part 91 of the plate 54 and riveted to the underside of the recessed part 91. The toothed pin 92 also has an actuating slot 93 on its upper side. His head 94 rests on the top of the two sliders 89.

Each slide, see FIG. 19, is approximately U-shaped and in the region of its end connecting the two webs to one another each has a projection 95 which engages in the longitudinal slot 88. The longer of the two In the area of its outside, leg 96 has a projection 97 which bears against the inside of the side walls 64 for guiding it. On the inside, the longer legs 96 each have a toothing 98, which is in engagement with the external toothing of the tooth bolt 92. 19, both slides 89 are pulled inwards so that their projections 95 are pulled inwards from the upper end regions of the longitudinal slots 88 and thus the adapter element is moved away from the hinge arm 86 becomes. The opposing arrangement of the two slides 89, together with the symmetrical arrangement of the slots 88, has the advantage that, without additional guide elements, the parallel displacement runs perpendicular to the surface 76 of the furniture body 7, exactly as in the embodiment according to FIG. 17.

To cover the assembled hinge, it can be provided according to the invention that a cover 99 is placed on the part of the hinge attached to the body wall, which cover can be fixed, for example, by snapping in or also pushed on. The cover hood 99 can be shaped such that it covers all parts of the hinge and has a smooth surface shape. The cover 99 shown in top view in FIG. 20 has two side lugs 100 assigned to the wings 3 of the cover plate, which have a lower height than the rest of the cover 99, see in particular FIG. 21. With the aid of the lugs 100, an alignment of the Cover 99 on the hinge. The front edge 101 of the cover 99 extends in the closed state up to the corresponding side of the top element 78.

While in the embodiment of the hinge arm, which is shown in detail in FIG. 17, the hinge arm is parallel 22 and 23 shows an illustration in which the adjustment takes place in a swiveling movement. An adapter element 102, on which the hinge arm 103 is adjustably mounted, is clipped onto the base plate in the same way as in the aforementioned embodiment. The hinge arm 103 is constructed in the region of its right end in FIG. 22, ie the end facing the door, in the same way as in the embodiment according to FIG. 17, so that this part is no longer described. The adapter element 102 in the form of an adapter plate contains a pair of outwardly directed axle journals 104 and 105 in the area of both ends. Each pair of axle journals 104, 105 could also be designed as a continuous axle.

The hinge arm 103, which is U-shaped in cross section, has a U-shaped slot 106 in the region of its end facing away from the door 77, the width of which slot corresponds approximately to the diameter of the stub axle 104.

In the area of its opposite end, the contains

Hinge arm 103 has a slot 107 extending over an arc, the width of which corresponds to the diameter of the stub axle 105, the center of the arc being in the end region of the slot 106.

The hinge arm 103 contains an adjustment screw 108 screwed through a thread, which engages with its free end in an opening of the adapter element 102, see FIG. 22. When the adjustment screw 108 is rotated, the hinge arm 103 pivots about that due to the engagement of the

Axle stub 104 formed in the slot 106 pivot point. The front slot 107, together with the stub axles 105 arranged there, serves to guide the hinge arm 103. FIG. 24 shows a representation corresponding to FIG. 3 in the case of an embodiment which has been slightly changed compared to FIG. 3. While the threaded screw 28 in the embodiment of FIG. 3 presses two strips 24, 26 outwards and thereby against parts of the cover plate 11, the base plate 110 of the embodiment according to FIG. 24 contains a region 111 which is slightly offset from its underside and which the area lying in front of and behind the plane of the drawing in FIG. 24 is separated by a slot. As a result, the offset area, which is still essentially parallel to the underside, can be bent somewhat. At the free end of the raised area 111, a bent tab 112 is formed, which extends almost at right angles to the area 111. The edge of the cover plate is also slightly deviated from the straight shape in this area, so that the tab 112 lies flat against the inside of the edge. When the threaded screw 28 is screwed in, it presses on the region 111, which can pivot somewhat, so that the outside of the tab 112 is pressed against the inside of the edge of the cover plate 11. This leads to jamming and thereby fixing the cover plate 11 to the base plate 110.
