[0026] Further details and advantages of a hinge according to the invention as well as of a method for adjusting the hinge are to be explained in an exemplary manner hereunder by means of two exemplary embodiments of the invention which are schematically illustrated in the figures in which:

DETAILED DESCRIPTION
[0036] Hinges 1 have two hinge elements 2, 3 which are articulated so as to be mutually pivotable and which enable a closing element such as, for example, a door leaf, a porthole window, window leaf, a cover, or a hatch, to be pivoted in relation to a frame. To this end, a hinge element 2 is disposed on the closing element, and a hinge element 3 is disposed on the frame. An opening which is surrounded by the frame and which can be, for example, a door, a porthole, or a window, herein can be closed or released in a simple manner.
[0037] In order for uniform closing of the opening by the closing element to be enabled and also for a sealing element, such as a sealing lip or a sealing bead, which is disposed between the frame and the closing element to be compressed herein for sealing, the hinge 1 has to be aligned. The hinge 1 according to the invention enables a simple and precise alignment. Two potential exemplary embodiments of said hinge 1 are to be discussed in more detail hereunder by means of the figures. According to the invention, the frame does not have to be a separate element. The frame can also be formed by the edge of a wall or similar that surrounds the opening.
[0038]
[0039] The box-shaped hinge element 2 and the elongate hinge element 3 are preferably composed of injection-molded plastics material but may also comprise metallic elements, in particular in the region of the hinge axis A, or be completely composed of metal.
[0040] The illustrated hinge 1 is configured in the manner of a closure hinge. Said hinge 1 has an activating device 6 which is disposed on the hinge element 2, the function of said activating device 6 yet to be described in more detail.
[0041] The two hinge elements 2, 3 are connected to one another by way of a hinge axis A in an articulated manner such that said two hinge elements 2, 3 can be mutually pivoted. The hinge axis A runs so as to be substantially parallel to the plane of the closing element (not illustrated). In order for the spacing of the hinge axis A in relation to the hinge element 3 to be adjusted, the illustrated hinge 1 has two actuating elements 5, wherein a single actuating element 5 would however also be sufficient for adjusting the space of the hinge axis A according to the invention.
[0042] The actuating elements 5 for visualization are illustrated so as to be spaced apart in relation to the hinge elements 2, 3 in
[0043] As can be seen in
[0044] In order to be disposed on the axle support 4, the actuating element 5 by way of a groove 5.2 has a circumferential constriction. The groove 5.2 is delimited by the thread 5.1 and the head 5.3 but may nevertheless also be spaced apart from said thread 5.1 and said head 5.3. The groove 5.2 enables a rotatable yet axially fixed disposal on the axle support 4. To this end, the groove 5.2 is configured in the manner of a variation of the radius which is abruptly sent back toward the inside. This enables the groove 5.2 to be mounted in a form-fitting manner in the bearing opening 4.1. Shear and traction forces for setting the spacing in relation to the hinge element 3 herein can be transmitted from the actuating element 5 to the axle support 4.
[0045] The hinge element 3 illustrated in
[0046] Apart from the protrusions 3.02, the hinge element 3 has in each case one countersink 3.5 in which a connection recess 3.2 is located. Said connection recess 3.2 herein serves for disposing the hinge element 3 on the frame, wherein a connecting means (not illustrated) such as, for example, a screw or a rivet, is guided through the connection recess 3.2. The hinge element 3 can in this way be connected directly to the frame, or can be connected to one or a plurality of further elements for disposal on the frame. The countersink 3.5 ensures that the connecting means does not protrude from the side 3.01 of the hinge element 3 and does not impede the actuating movement of the axle support 4.
[0047] A recess 3.3 which is disposed between the mating threads 3.1 in the assembled state of the hinge 1 permits a free rotating movement of the hinge element 2 which is disposed about the hinge axis A. Any collision of the regions of the hinge element 2 that are disposed about the hinge axis A of the axle support 4 and the hinge element 3 is avoided on account of the recess 3.3. The hinge element 2 is provided with sufficient freedom of movement even at a minor spacing of the hinge axis A from the hinge element 3.
[0048] The hinge element 3 moreover has a guide region 3.4 for guiding the actuating movement of the axle support 4. Said guide region 3.4 interacts with a guide region 4.4 of the axle support 4 illustrated in
[0049] The hinge element 3 and the axle support 4, by way of the guide 3.4, 4.4, are configured in the manner of interacting plug-fit connection elements. The axle support 4 by way of the guide region 4.4 herein partially encompasses the hinge element 3 along the section plane illustrated in
[0050] The axle support 4 according to
[0051] Passages 4.2 render the connecting means accessible from the outside in order for the hinge element 3 to be connected by way of the connection recesses 3.2, without the axle support 4 having to be removed to this end. For this purpose, the passages 4.2 are disposed on the axle support 4 in such a manner that said passages 4.2 in the assembled state of the hinge 1 are aligned with the connection recesses 3.2.
[0052] The bearing openings 4.1 are disposed on both sides of the joint pin 4.3, a disposal of the actuating elements 5 on both sides being achieved on account thereof. The two actuating elements 5, apart from adjusting the spacing of the hinge axis A in relation to the hinge element 3, also enable the hinge axis A to be inclined. A distortion of the closing element and/or of the frame due to production tolerances or use can be equalized by the adjustable oblique positioning of the hinge axis A. Dissimilar spacings between the hinge axis A and the hinge element 3 are adjusted herein by means of the actuating elements 5, on account of which an inclination of the hinge axis A in relation to the hinge element 3 results.
[0053] As described above, the actuating element 5 is mounted in a bearing opening 4.1 of the axle support 4. The bearing opening 4.1 has a bearing region 4.11 and a plug-fit region 4.12. The plug-fit region 4.12 is dimensioned so as to be larger in comparison to the bearing region 4.11. This enables the actuating element 5 to be plug-fitted in the plug-fit region 4.12 with the thread 5.1 and/or the head 5.3 leading. To this end, the internal radius of the plug-fit region 4.12 is at least the size of the external diameter of the thread 5.1 and/or of the head 5.3 of the actuating element 5.
[0054] In contrast, the bearing region 4.11 has an internal diameter which is less than the external diameter of the thread 5.1 and/or of the head 5.3 of the actuating element 5. On account of said smaller internal diameter of the bearing region 4.11 it is prevented that an actuating element 5 that is mounted in the bearing region 4.11 can depart from the bearing region 4.11 in the axial direction. An axial restriction of the freedom of movement of the actuating element 5 is achieved. The radius of the bearing region 4.11 corresponds substantially to the external diameter of the groove 5.2 of the actuating element 5. The axial dimension of the bearing region 4.11 likewise corresponds substantially to the axial length of the groove 5.2. The groove 5.2 can in this way be mounted in a form-fitting manner in the bearing region 4.11. The shear and traction forces for adjusting the spacing from the hinge element 3 are thus transferred from the actuating element 5 to the axle support 4.
[0055] The bearing region 4.11 and the plug-fit region 4.12 form a keyhole-shaped bearing opening 4.1 in which the two substantially circular regions 4.11 and 4.12 are connected to one another by way of an elongate bore which runs between the two regions 4.11, 4.12. The smaller diameter of said elongate bore herein corresponds substantially to the internal diameter of the bearing region 4.11.
[0056] In order for the head 5.3 of the actuating element 5 to be received, the bearing opening 4.1 is disposed in a countersink 4.6. This enables the actuating element 5 to be mounted in the bearing opening 4.1 and prevents the head 5.3 from projecting from the upper side of the axle support 4.
[0057] The bearing opening 4.1 and the guide region 4.4 are mutually disposed in such a manner that the actuating element 5, which in the case of the assembled hinge 1 in which the guide region 4.4 bears on the guide region 3.4 is established by way of the mating thread 3.1, cannot be transferred from the bearing region 4.11 to the plug-fit region 4.12. Any unintentional departure of the actuating element 5 from the bearing opening 4.1, and thus a release of the axle support 4 from the actuating element 5, is prevented in the assembled state.
[0058] When assembling the hinge 1, the actuating element 5 is first plug-fitted in the plug-fit region 4.12 of the axle support 4 and, in order for the groove 5.2 to engage in the bearing region 4.11, is displaced transversely to the plug-fitting direction. The actuating element 5 mounted in the axle support 4 is subsequently connected to the hinge element 3 by means of the thread 5.1 and the mating thread 3.1. Alternatively, an engagement between the thread 5.1 and the mating thread 3.1 is first established, and the axle support 4 is subsequently plug-fitted on the actuating element 5 in such a manner that the actuating element 5 is plug-fitted in the plug-fit region 4.12. Thereafter, the axle support 4 is displaced in relation to the actuating element 5 and the hinge element 3 in order for the actuating element 5 to be transferred to the bearing region 4.11. The second alternative requires that the axle support 4 by way of the actuating element 5 can be spaced apart from the hinge element 3 in such a manner that the guide regions 3.4, 4.4 no longer bear on one another.
[0059]
[0060] In order for the spacing D1 to be varied and thus also for the spacing of the hinge axis A disposed on the axle support 4 from the hinge element 3 to be adjusted, the adjustment element 5 is rotated about the longitudinal axis thereof. On account of the interaction between the thread 5.1 and the mating thread 3.1, this rotating movement is converted to an axial longitudinal movement of the actuating element 5. A shear or traction force exerted on account of the axial longitudinal movement is transferred to the axle support 4 by way of the axial fixing of the actuating element 5 described above. The axle support 4 by way of the shear or traction force is moved away from the hinge element 3 or toward the latter and herein is guided by the guide 3.4, 4.4.
[0061] The maximum achievable spacing D2 which still permits a guided movement is shown in
[0062]
[0063] A link eye 2.1 which is open on one side permits the link eye 2.1 to be released and locked in a simple manner on the joint pin 4.3. To this end, the hinge element 2 has a locking mechanism 2.3 which can be seen in
[0064] The activating device 6 which is configured in the manner of a handle and is disposed in the recess 2.4 of the hinge element 2 serves for activating the locking mechanism 2.3.
[0065] The hinge 1 equipped with a locking mechanism 2.3, apart from the function as a hinge, can at the same time also be used in the manner of a closure hinge for closing and/or locking. The hinge 1 can thus be used as a replacement for or as an addition to a lock. If a plurality of said hinges 1 are used at various locations of the closing element of a closable opening, said hinges 1 can enable the opening direction of the closing element to be selected. The link eye 2.1 of the hinge 1 about which the closing element is to be pivoted, herein can remain in a position locked to the joint pin 4.3, while the link eyes 2.1 of the remaining hinges 1 by moving the respective locking mechanism 2.3 are released from the joint pins 4.3 assigned to said link eyes 2.1. The closing element in this instance can be pivoted about the hinge 1 which is still locked. In order for the closing element to be locked in the closed position thereof, the respective joint pins 4.3 and link eyes 2.1 of the hinges 1 are locked to one another. Particularly stable locking of the closing element can be achieved in this way.
[0066] A further exemplary embodiment of a hinge 1 according to the invention is to be discussed hereunder. Elements with equivalent functions herein are identified by the same reference signs as have already been used in the description of the first exemplary embodiment. The substantial difference in comparison to the first exemplary embodiment lies in design details of the hinge element 3 and of the axle support 4. Only the points of differentiation in relation to the first exemplary embodiment will therefore be discussed hereunder, wherein the description above to this extent also applies to the second exemplary embodiment.
[0067]
[0068]
[0069] As can be seen in
[0070] In order for the actuating elements 5 to be mounted, the axle support 4 again has keyhole-shaped bearing openings 4.1 which are disposed in countersinks 4.6. The two bearing openings 4.1 are mutually aligned in such a manner that the bearing regions 4.11 of the two bearing openings 4.1 face one another. An additional safeguard against the actuating elements 5 departing from the bearing openings 4.1 is achieved on account thereof.
[0071] Since the grooves 5.2 prevent any departure of the actuating elements 5 from the bearing regions 4.11 in the axial direction, the actuating elements 5 would have to be transferred to the larger plug-fit regions 4.12 in order to be able to depart from the latter. However, by virtue of the disposal of the bearing regions 4.11 so as to align with the mating threads 3.1, an actuating element 5 that is connected to the mating thread 3.1 cannot be freely transferred to the plug-fit region 4.12. The mutually facing bearing regions 4.11 of the bearing openings 4.1 moreover prevent that the axle support 4 in relation to the actuating elements 5 which are established relative to the hinge element 3 is displaced in such a manner that the actuating elements 5 enter the plug-fit regions 4.12. This is because the axle support 4 to this end would have to be moved along the hinge axis A in another direction for each of the two actuating elements 5. Such a movement which corresponds to a compression of the axle support 4 is not possible in the case of the fixed axle support 4. Therefore, the actuating elements 5 cannot depart from the bearing opening 4.1 without being released from the hinge element 3.
[0072] An alignment which is simpler and more precise can be achieved by using the hinge 1 described above and the method for adjusting the hinge 1.
