(11) FIG. 10 shows the hinge according to FIG. 2 along a cutting path marked X-X in FIG. 11, and

(12) FIG. 11 is a plan view of the hinge according to FIG. 1.

(13) FIG. 1 shows a hinge according to the invention, said hinge being what is known as a cup hinge. Of course, the invention can also be applied to other types of hinges and is not limited to cup hinges. The explanations below therefore apply both to cup hinges and to other hinge types.

(14) The hinge comprises two hinge parts 100, 200. These two hinge parts 100, 200 are hingedly interconnected by means of a hinged connection. The first hinge part 100 comprises a hinge cup 105. A limiting element 101 indirectly or directly adjoins the hinge cup 105. Said limiting element 101 may be plate-like and is used to limit the insertion movement of the hinge cup 105 into a milled recess of a part of an item of furniture, the limiting element 101 striking the top of the element of the item of furniture, around the milled recess. The limiting element 101 may for example, as shown in the figure, comprise extensions 102 that extend on opposing sides of the hinge cup 105. The extensions 102 comprise receptacles. The fastening elements 103 are pushed through the receptacles. The fastening elements may be formed by fastening screws. In this case, the fastening screws can be screwed into anchors 104 in a pre-mounting position, as shown in the figure.

(15) A damping device 109 is received in the hinge cup 105. In this case, the damping device 109 may comprise a fluid damper. This fluid damper may for example be an air damper or a liquid damper. The fluid damper may be formed as a linear damper for example, said damper comprising a damping cylinder in which a piston is linearly adjustable. A piston rod may be coupled to the piston. The damping device 109 can be covered by a cover 107 in order to be fixed securely in the hinge cup 105 for example, the cover 107 being connected to the first hinge part 100.

(16) According to a preferred variant, it is furthermore also possible to use a switching means. The damping effect of the damping device 109 can be adjusted or at least in part prevented thereby. It is conceivable, for example, for the switching means to block the damping means 109 in the compressed or partially compressed state thereof, i.e. when the piston has been inserted completely or in part into the cylinder. In this state, no or just a short damping path is provided. The switching means may comprise an actuator 108. As shown in FIG. 1, the actuator 108 is user-friendly and is easily accessible from the front of the hinge cup 105.

(17) The two hinge parts 100, 200 are interconnected by means of a hinge arm 207. The hinge arm 207 is integrally attached to the second hinge part 200 in order to reduce the outlay for parts. It is also conceivable, however, for the hinge arm 207 to be attached to the first hinge part 100 or to be a separate component. In the present embodiment, the hinge arm 207 is fastened to the hinge cup 105 by means of a hinge pin 106. The hinge arm 207 comprises a gudgeon 208 that is integrally molded on and through which the hinge pin 106 is guided. The pivot axis is thus arranged in the region of the hinge cup 105. The hinge arm 207 is designed and arranged so as to also be used for operating the damping means 109. In this respect, a convexly curved contour (visible in FIG. 1) of the hinge arm 207 strikes an actuation element of the damping device 109 (see reference sign 109 in FIG. 1) during the closing movement of the hinge proceeding from the open position shown in FIG. 1. In this case, the damping cylinder and the piston that is guided therein are adjusted relative to one another.

(18) The second hinge part 200 comprises a plate 201. The hinge arm 207 is integrally molded onto said plate 201. A recess 202 passes through the plate 201. Extensions 203 bend off on opposing sides of the plate 201. The ends of the extensions 203 that are turned away from the bend region comprise an end portion 204 having a curved contour.

(19) A thread receptacle 205 may be provided in the plate 201. An adjustment element 206, preferably in the form of an adjustment screw, is inserted into said thread receptacle 205.

(20) As can furthermore be seen in FIG. 1, the second hinge part comprises a support portion 210 that is molded on. Said support portion 210 comprises a screw receptacle. A fastening screw 209 can be pushed through said screw receptacle.

(21) A mounting element 300 can be connected to the second hinge part 200. The structure of the mounting element 300 can be seen in greater detail in FIGS. 9 to 11. As these drawings show, the mounting element 300 comprises a base part 301. Chamfers 302 are provided on the two opposing sides of the base part 301. The two extensions 203 of the second hinge part in each case rest on the outside of said chamfers 302, as shown in FIG. 10. The chamfers 302 thus form a positive contact means for the extensions 203 in the direction of the hinge axis. Transition portions 303 adjoin the chamfers 302. Said transition portions 303 are bent off from the chamfers 302 and are preferably aligned so as to be at right-angles thereto. The transition portions 303 each carry a centering element 304. Centering elements 304 are thus provided on both sides of the mounting element 300. The centering elements 304 comprise at least one guide surface 306, 307. In the preferred embodiment shown in the drawings, two guide surfaces 306, 307 are provided per centering element 304.

(22) As can be seen in FIG. 1, the mounting element 300 extends in the direction of the longitudinal axis L of the hinge, the longitudinal axis L also simultaneously defining the joining direction of the mounting element 300 into the retaining part 400. The mounting element 300 is preferably symmetrical with respect to the longitudinal axis L. The first guide surface 306 mentioned above extends so as to be inclined and at the angle of the longitudinal axis L, the guide surface 306 extending so as to be inclined inwardly proceeding from an end facing the first hinge part 100 in FIG. 1, i.e. so as to be inclined towards the component center of the mounting element 300. The two guide surfaces 306 of the centering element 304 thus extend so as to be inclined at an acute angle relative to one another. An angle between the guide surfaces 306 can preferably be in the range between 1 and 10°.

(23) The second guide surfaces 307 that are provided in addition and/or alternatively extend proceeding from the end facing the first hinge part 100 in FIG. 1 towards the end remote from the first hinge part 100 in a sloping, and thus inclined, manner. In this case, the inclination angle can preferably be in the range between 0.5 and 5°.

(24) As can further be seen in FIG. 1, stops 305 are also molded on the mounting element 300, on opposing sides. It is also conceivable to use just one stop 305.

(25) According to FIG. 3, two latching extensions 308 are provided on the region of the mounting element 300 remote from the first hinge part 100. The function of said latching extensions 308 will be explained later.

(26) As can be seen in FIG. 1, the retaining part 400 is used. The design of the retaining part 400 can be seen more clearly in FIGS. 4 to 8. As these drawings show, the retaining part 400 comprises a fastening portion 401. The fastening portion 401 is plate-like. Said portion comprises an opening in the form of a screw receptacle 402. Guides 405 are provided on sides of the retaining part 400 that are opposing with respect to the longitudinal axis L. In this case, the guides 405 each form a first centering guide 406. In addition and/or alternatively, a second centering guide 407 may also be provided. The centering guides 406, 407 are designed so as to be complementary to the guide surfaces 306, 307. Accordingly, the centering guide 406 extends so as to be at an angle and inclined inwardly proceeding from the insertion region of the retaining part 400 facing the first hinge part 100, towards the end of the retaining part 400 remote from the insertion region. In this respect, the two centering guides 406, which may be planar according to the present embodiment, are at an acute angle relative to one another, the angle preferably being selected in accordance with the pitch of the guide surfaces 306, 307. The pitch of the centering guides 406 results in a guide receptacle for the mounting element 306 that tapers in the direction of the longitudinal axis L.

(27) The centering guides 407 can be designed so as to be complementary to the guide surfaces 307 of the mounting element 300. Said guides accordingly extend so as to be inclined, proceeding form the insertion region. Accordingly, a tapering receptacle is provided in the direction of the longitudinal axis L, proceeding form the insertion region between the fastening portion 401 and the regions of the second centering guides 407 associated in each case. The inclined pitch of the centering guides 406 and 407 can be seen in FIG. 5 and in the enlarged view in FIG. 7. In FIG. 8, the pitch angle α shows the inclined pitch of the first centering guides 406 relative to the longitudinal axis L and to one another. In FIG. 6, the pitch angle β shows the inclined pitch of the second centering guide 407 relative to the top of the fastening portion 401.

(28) As can be seen in the drawing according to FIG. 8, one or two bearing pieces 409 are molded onto the fastening portion 401. Said bearing pieces are preferably chamfered off from the fastening portion 401. The bearing pieces 409 comprise a bearing receptacle. The bearing receptacle is in alignment with a bearing receptacle of a release element 411. The release element 411 is pivotably connected to the retaining element 400 by means of a bearing 410, preferably a bearing pin, that is guided through the mutually aligned bearing receptacles.

(29) In the preload state shown in FIG. 1, the release element 411 is aligned relative to the retaining part 400 by means of a spring 412. The release element 411 comprises a hand-operated actuation surface (see the corrugated upwardly facing surface in FIG. 1). On this actuating surface, the release element 411 can be pivoted into the bearing 410 counter to the preload of the spring 412. The release element 411 comprises one, preferably two, latching elements 413. As shown in FIG. 1, said latching elements 413 are provided on both sides of the release element 411.

(30) The latching element 413 comprises a deflection slope 414 that extends so as to be inclined in the direction of the longitudinal axis. The deflection slope 414 transitions into a steep latching flank 415 in the opposing direction to the longitudinal axis L.

(31) In order to mount the hinge shown in the drawings, the retaining part 400 is initially attached to a carcass of an item of furniture. Alignment elements 403, 404 protrude on the underside of the retaining part 400. The retaining part 400 can be aligned to associated surfaces, for example to a frame profile of the part of the item of furniture, by means of said alignment elements 403, 404. In order to fasten the retaining part 400 on the part of the item of furniture, a fastening screw is guided through the screw receptacle 402 of the retaining part 400 and screwed into a thread receptacle of the carcass of the item of furniture. The pre-mounted module shown in FIG. 1 can now be mounted on the retaining part 400 that is fixed in this way. For this purpose, the free end of the mounting element 300 is pushed into the guides 405. This is achieved in a simple manner, since the first centering guides 406 align the mounting element 300 in a first mounting direction that extends in the direction of or substantially in the direction of the hinge axis (axis of the hinge pin 106). In this case, the first guide surfaces 306 are guided and aligned on the first centering guides 406. At the same time, alignment of the mounting element 300 in a second mounting direction that extends transversely to the first mounting direction is brought about in the event of the mounting movement in the direction of the longitudinal axis L. In this case, the second guide surfaces 307 of the centering elements 304 are accordingly aligned to the second centering guides 407 of the guides 405, in a plane extending transversely to the hinge axis. The association brought about thereby between the guide surfaces 306, 307 and the centering guides 406, 407 can be seen in particular in FIGS. 9 and 10, which show the hinge in the mounting position.

(32) During the joining process, the latching extensions 308 glide on the deflection slopes 414 of the release element 411. As a result, the release element 411 is pivoted about the pivot axis of the bearing 410. As soon as the latching extensions 308 have passed the deflection slopes 414, the release element 411 snaps back into the upright position thereof shown in FIG. 1, the latching extensions 308 engaging behind the latching flanks 415. This brings about the firm association between the mounting element 300 and the retaining part 400. At the same time, the joining movement is also limited by the stops 305. Said stops 305 strike the retaining part 400. According to the present embodiment, the stops 305 strike the end of the first centering guides 406 at the end of the end of the guides 405 facing the insertion region. Of course, a stop connection to a stop 305 for limiting the joining movement relative to the retaining part 400 may also be provided at any other point. Limiting the joining movement by means of a stop 305 prevents the guide surfaces 306, 307 of the mounting element 300 from clamping onto the associated centering guides 406 and/or 407 in a wedge-shaped manner, which would impede dismantling in particular if the pitch angles of the guide surfaces 306, 307 or of the centering guides 406, 407 were selected to be so small that self-locking would occur in the wedge connection.

(33) The second hinge part 200 is screwed to the mounting element 300 by means of the fastening screw 209. For this purpose, the fastening screw 209 is inserted through a screw receptacle in the support portion 210 and screwed into a thread receptacle of the mounting element 300. Consequently, the module on the left in FIG. 1 is thus associated with and fastened to the retaining element 400 in a precisely positioned and aligned manner.

(34) It may be the case that it is necessary to adjust the hinge in order to align a door that is fastened to the hinge. The alignment can be carried out in two planes, using the hinge shown in the drawings. Alignment in the direction of the hinge axis can be carried out by releasing the screw that is inserted through the screw receptacle 402 of the retaining part 400. This is easily possible on account of the mutually aligned recesses 202, 309 in the second hinge part 200 and in the mounting element 300, respectively. A screwdriver can access the screw head of the fastening screw through said recesses 202, 309. When the fastening screw is released, the retaining part 400 can be adjusted in a limited manner in the direction of the hinge axis, since the cross section of the screw shank is smaller than the extent of the screw receptacle 402 in the direction of the hinge axis. Alignment of the hinge perpendicularly to the hinge axis can be carried out by means of the adjustment element 206. For this purpose, the fastening screw 209 is first released. The adjustment element 206, designed as an adjustment screw, can then pivot the second hinge part arm 200 relative to the mounting element 300. This is possible because the end of adjustment screw remote from the screw head is supported on a support region of the base part 301 of the mounting element 300 and said adjustment screw is simultaneously screwed into a thread receptacle 205 of the hinge arm 207. As soon as the desired adjustment position is reached, the fastening screw 209 can be tightened again. During adjustment by means of the adjustment screw, the pivoting of the hinge arm 207 relative to the mounting element 300 occurs about an axis that is located substantially in the region of the support portion 210. In order to prevent a collision with the mounting element 300, the end portions 204 of the extensions 203 have the curved contour mentioned above. This makes it possible to achieve a small overall height.

(35) In order to dismantle the door, it is merely necessary for the release element 411 to be actuated by hand and pivoted about the pivot axis of the bearing 410. In the process, the latching extensions 308 are then disengaged from the latching flanks 415 of the release element 411. Subsequently, the mounting element 300 can be removed from the guides 405 of the retaining part 400. This is achieved simply and without using much force, on account of the use according to the invention of centering guides 406, 407. In particular, no high friction forces need to be overcome here.

(36) Within the meaning of the invention, the hinge described above thus comprises two interconnected hinge parts 100, 200, the second hinge part 200 carrying or comprising a mounting element 300. The mounting element 300 comprises at least one guide assembly comprising at least one guide 405 that extends in the direction of a longitudinal axis L of the mounting element 300. In the mounting position, the mounting element 300 is connected to a retaining part 400 and the guide assembly acts between the mounting element 300 and the retaining part 400, by means of which guide assembly the mounting element 300 can be moved into a mounting position in a manner guided in the guide direction. The guide assembly comprises at least one first centering guide 406, by means of which the mounting element 300 is aligned in a first mounting direction when adjusted in the guide direction L.
