Description

The invention relates to a single-axis hinge according to the preamble of claim 1.

Single-axis hinges are known for example from DE 80 27 427 U. Special advantages of these single-axis hinges can be seen in the flat frame part, which allows maximum use of the interior of the cabinet.

A single-axis hinge is known from DE 80 30 213 U, which has a frame part composed of two parts, the frame part articulated on the hinge arm being braced by means of a central clamping screw against the lower frame part previously anchored in the wooden frame. The advantage of this construction is that when the furniture is assembled, the relatively small base plate can be anchored in the factory in a rational manner, for example automatically in the context of the furniture, by means of a plurality of screws which are inserted in accordance with the load. The door with the hinge completely attached to it is positively attached to the lower frame plate put on and clamped with a clamping screw using a screwing tool. Another disadvantage of this prior art is that the two frame parts rest on one another and therefore the frame part does not have the required flatness.

Single-axis hinges are also known which enable quick assembly without tools. According to the prior art, this is done by a form-fitting, spring-loaded connection between the door-side hinge end and the interior of the pot embedded in the door. The desired flatness of the fixed frame part can advantageously be maintained by the quick assembly in the wing-side pot part of the single-axis hinge. The disadvantage of this prior art, however, is that during the assembly process, in particular when the frame hinge part is first connected to the corresponding wing hinge part in the wing-side pot of a door, the pressure required to overcome the locking spring force must be applied against the door which is still loose in the room. This is particularly problematic with large doors if only one operator is provided. Furthermore, such a construction has the disadvantage that the wing-side side adjustment of the door is no longer possible, since the clamping screw, which is usually mounted in an elongated hole, is omitted in the wing pot.

The invention has for its object to provide a tool-free assembled single-axis hinge that simplifies the assembly process while maintaining a flat frame part and allows side adjustment of the door leaf.

The features of claim 1 serve to achieve this object.

Characterized in that the frame hinge part consists of at least two mutually adapted frame parts, which are arranged in a common plane and can be locked together by a pushing or pivoting movement, both frame parts having essentially the same structural height and both frame parts resting on the frame, a single-axis hinge is created that the tool-free quick assembly enables the side adjustment of the door leaves to be maintained, has a flat frame hinge part and also enables the height adjustment of the frame hinge part.

The flat structure of the frame hinge part is therefore achieved in that the two frame parts lie side by side directly on the frame, the two frame parts being locked together in the desired end position.

It is preferably provided that the first frame part hooks into at least a first point of the second frame part and is resiliently clamped into a second point of the second frame part. In this way, the two frame parts can be joined together with a simple pivoting movement of the first frame part. With the help of a spring, the two frame parts can be biased against each other. The spring can also be used to secure the snap connection.

In a preferred embodiment it is provided that a leaf spring generates the bias. A Leaf spring is particularly advantageous because it has a high clamping force with an extremely flat design.

The leaf spring can be captively attached to the first frame part.

The second frame part advantageously has undercuts, under which the first frame part can engage. The undercuts enable a highly resilient connection between the two frame parts, whereby forces can be effectively absorbed by the second frame part, which arise when the door wing is stretched beyond the opening angle and tend to lift the frame hinge part off the frame.

In a preferred embodiment it is provided that the first frame part surrounds the second frame part in a ring. In this way, a large connection area is created between the two frame parts, which distributes the forces over the entire circumference of the frame parts.

In a further exemplary embodiment it is provided that the frame parts are hooked to one another at at least one point and are pretensioned at a second point via a tensioning lever against a projection cooperating with the tensioning lever and against the hooking. In this embodiment, the clamping force is applied via a clamping lever which clamps the frame parts against one another, the hooking of the frame parts at the first point preventing the first frame part from being lifted off the second frame part.

It can be provided that the clamping lever is mounted in the first frame part and the projection on the second frame part. To apply the clamping force, the clamping lever can be provided with an eccentric clamping surface, which increasingly presses against the projection as the clamping lever swivels into its flat end position.

It is preferably provided that the clamping lever is mounted on a clamping sleeve. In addition to the clamping effect that can be achieved via the material deformation, the clamping sleeve enables the transmission of a higher clamping force with the clamping lever, whereby manufacturing tolerances can also be compensated for in an advantageous manner.

In a further exemplary embodiment it is provided that the frame parts are hooked to one another at at least one point and are pretensioned against the hooking at a second point by means of a spring lever consisting at least partially of a leaf spring. Such a single-axis hinge can be manufactured inexpensively.

The spring lever can undercut an undercut of the second frame part at one end and snap into place at the other end.

In a further embodiment it is provided that the second frame part consists of a profile rail and that the first frame part engages in the profiles of the profile rail and is hooked there. The spring lever can engage behind another undercut of the profile rail and the first Brace the frame part against the hooking.

In all of the exemplary embodiments it can be provided that the frame parts have inclined, mutually adapted support surfaces relative to the joint axis at an angle between approximately 30 ° and 60 °, preferably approximately 45 °. With the aid of these support surfaces, forces acting diagonally on the single-axis hinge can be supported in a particularly advantageous manner.

Exemplary embodiments of the invention are explained in more detail below with reference to the drawings.

Figure 1 shows the frame hinge part 4 of a single-axis hinge 1, which is attached to a frame 2. The single-axis hinge 1 consists of the plate-shaped frame hinge part 4 and a wing hinge part 6 fastened to a door leaf 3, in which the frame hinge part 4 has a fork part 9 receiving the joint axis 8. The wing hinge part 6 has a hinge arm 10 articulated on the fork part 9.

The hinge arm 10 is detachably connected to the wing hinge part 6 via a fastening screw 7 and thereby enables a lateral adjustment.

The frame hinge part 4 is formed in two parts and consists of a first frame part 12 which with the Fork part 9 is articulated on the hinge arm 10 and a second frame part 14 which can be preassembled on the frame 2. The second frame part 14 is provided with at least three bores 15, 17 for attachment to the frame 2. The rear bores 15 facing away from the hinge arm 10 are designed as elongated holes in order to enable height adjustment. The front bore 17 is used in particular to absorb forces when spanning the single-axis hinge 1 beyond its opening angle.

Both frame parts 12, 14 are plate-shaped and lie flat on the frame 2, the first frame part 12 completely enclosing the second frame part 14 in the exemplary embodiment according to FIG. 2. The front support surfaces 36 of the second frame part 14 facing the hinge arm 10 run at an angle of preferably approximately 45 ° relative to the hinge axis 8. The first frame part 12 has support surfaces 38 adapted to the support surfaces 36, which are also at an angle of approximately 45 ° run to the hinge axis 8.

The second frame part 14 preferably has a stop means 23, which is angled at right angles to the support surface and is arranged parallel to the articulated axis 8 and which serves as a mounting aid because when it is pressed into the bores 15 against the end face of the frame 2 it serves as an anti-rotation device.

The support surfaces 36 of the second frame part 14 are provided in the exemplary embodiment with three undercuts 22, specifically at the tip of the triangular front part of the second frame part 14, and at the ends of the support surfaces 38 facing away from the tip, the support surfaces 38 of the first frame part 12 being provided with a corresponding profiling which engage under the undercut 22.

The frame part 12 preferably has a captively preassembled leaf spring 20 at its rear end, which extends essentially parallel to the hinge axis 8 and to the frame parts 12, 14. In its central region, the leaf spring 20 has projections 21 projecting conically from its longitudinal and transverse extent, the projection 21 closer to the hinge arm 10 serving in particular to bias the first frame part 12 against the second frame part 14 in a direction pointing away from the hinge arm 10. The leaf spring 20 is captively supported at its ends in sections of the first frame part 12 that run orthogonally to the hinge axis 8. The first frame part 12 essentially surrounds the second frame part 14 in an annular manner.

The conical projection 21 of the leaf spring 20 can be against a rear e.g. likewise press conically shaped projection 13 of the second frame part 14, which has a recess 19 which serves to push back the projection 21 of the leaf spring 20 to release the hinge connection.

The projection 21 of the leaf spring 20 can hold the positively connected frame parts 12, 14 solely due to clamping, but it can also engage undercut the second frame part 14, for example on the projection 13.

The second frame part 14 is conventionally attached to the frame 2 by means of wood screws. Because the first frame part 12 has the same structural height as the second frame part 14 and the two frame parts 12, 14 lie side by side on the frame 2, the low structural height can be maintained. Since the separation of the hinge parts of the single-axis hinge takes place on the side of the frame hinge part, the wing hinge part can advantageously be designed in a conventional manner, i. H. with the possibility of side adjustment of the door.

FIGS. 5 and 6 show a further exemplary embodiment of the single-axis hinge 1 in which an essentially square second frame part 14 is provided, which has two rear bores 15 and two front bores 17. The second frame part 14 has in its center on the side facing the hinge arm 10 an essentially rectangular recess into which an essentially rectangular frame part 12 adapted to the recess can be inserted. The first frame part 12 engages under the rear undercuts 24 of the second frame part 14. In addition, front undercuts 25 are provided.

In the first frame part 12, a clamping lever 28 is mounted with the aid of a clamping sleeve 32 as an axis of rotation which runs parallel to the joint axis 8. The tensioning lever 28 has an eccentric clamping surface 30 which, when the tensioning lever is pivoted in the direction of the plate-shaped frame parts 12, 14, presses against a projection 26 of the second frame part 14 and braces the two frame parts 12, 14 against one another. The frame part 12 with the undercuts 24, 25 is secured at the first point 16 and at the second point 18 against lifting off from the frame part 14. The adapter sleeve 32 enables a compensation of manufacturing tolerances and enables the application of an increased spring force. In the tensioned state, the tensioning lever 28 does not protrude beyond the frame parts 12, 14.

A spiral pin can be used as the clamping sleeve 32. In a departure from the exemplary embodiment shown, it is also possible to mount the tensioning lever 28 in the second frame part, in which case the eccentric clamping surface 30 presses against a projection of the first frame part 12.

The second frame part 14 has a recess 27 into which a lever for releasing the tensioning lever 28 can be immersed.

In the embodiment of FIG. 7, the locking force is applied by a spring lever 40 mounted in the first frame part 12, the two ends of which are shaped so as to extend transversely to the hinge axis 8 in such a way that they engage in corresponding undercuts 22, 24 of the frame parts 12, 14. The spring lever 40 achieves a tensioning effect in which an unwanted loosening is prevented and loosening can only take place with the aid of a tool. For this purpose, the spring lever 40 has at its end facing away from the fork part 9 a projection 41, under which a lever tool can engage. The spring lever 40 is mounted on a rigid round web 42, which is part of the first frame part 12. The undercut 24, which is further away from the fork part 9, is formed on the first frame part 12 and is essentially round in cross section, the free end of the spring lever 40 being able to clip in via this rounding of the undercut 24.

In this exemplary embodiment, too, the first frame part 12 can engage undercuts 44 of the second frame part 14. The second frame part otherwise largely corresponds to the embodiment provided with a tensioning lever 28.

The spring lever 40 or tensioning lever 28, which braces the frame parts 12, 14 against one another, could also be mounted in a different way from FIG. 7 in the second frame part 14.

In the exemplary embodiment shown in FIG. 9, the second frame part consists of a profile rail 34, for example made of aluminum, which is fastened in a known manner, for example on an end face of the frame 2. The first frame part 12 hooks into an undercut 35 of the profile rail 34 with a hook-shaped projection 37. A spring lever 40, which is pivotably mounted in the first frame part 12, engages when depressed with its end facing the fork part 9 - similar to that described previously Exemplary embodiment - behind a further undercut 39 of the profiled rail 34 and thus braces the hook-shaped projection 37 against the profiled rail 34. The spring lever 40 of the exemplary embodiment according to FIGS. 9 and 10 has at its end two leaf spring parts 44 and 46 which extend parallel to the joint axis 8 that can get caught in the first frame part 12. This can take place, for example, at the free ends of the spring leaf parts 44, 46, as shown in FIG. 11. With the aid of a recess 48 in the central region between the leaf spring parts 44 and 46, the engagement of the spring lever 40 can be released again.

12 shows another exemplary embodiment for the clamping of the spring lever 40.

The undercuts 35, 39 required for clamping are formed by molded, continuous profile grooves, which allow the height position of the single-axis hinge to be shifted continuously.

In addition, a raster row bore 50 made in the profile rail 34 can be used for taking preferred positions by means of centering pins 66 cast onto the frame part 12.

FIGS. 13 and 14 show a further exemplary embodiment for fastening the single-axis hinge to a profile rail 34. In contrast to the exemplary embodiment of FIGS. 9 to 12, in this exemplary embodiment, as can best be seen from FIG. 14, the first frame part 12 hooks into undercuts 35 and 45 of the profile rail 34 with two hook-shaped projections 37, 43. Similar to FIG. 10, only a hook-shaped projection 37 can also be provided. The hook-shaped projection 43 engages an undercut 45 on the free end face of the profile rail 34. The spring lever 40, which, as in the exemplary embodiments in FIGS. 9 to 12, is pivotably mounted in the first frame part 12, engages behind the further undercut 39 of the profiled rail 34 with its end facing the fork part 9 and thus braces the hook-shaped projections 37, 34 against the profiled rail 34. In this exemplary embodiment, the spring lever 40 extends in its longitudinal direction transversely to the hinge axis 8 between two side parts 52, 54 of the first frame part 12 which also extend transversely to the hinge axis 8 In the middle region of the spring lever, a hook-shaped projection 56 protrudes from the profile rail 34, which resiliently engages behind a projection 58 of the first frame part 12 which is shaped to be complementary thereto, whereby the spring lever 40 is locked. The spring lever 40 can be released from its latching by lifting by means of a handle 60 of the spring lever 40 which is angled from the profile rail 34.

Similar to FIG. 12, a grid row bore 50 made in the profiled rail 34 can also be used for taking preferred positions by means of centering pins 66 cast onto the frame part 12.

In addition to the positioning of the respective hinge part, the centering pins 66 also have the task of absorbing forces and torques that occur.
