Description

[0001] The invention relates to a hinge, particularly for glass doors, comprising two hinge parts pivotally connected to each other about a pivot axis and a locking device effective between the two hinge parts, which essentially consists of at least one locking element assigned to the first hinge part and movably guided against the action of at least one spring element, and a locking body assigned to the second hinge part with at least one locking recess cooperating with the locking element in a locking position, wherein the locking body is arranged coaxially to the pivot axis between two hinge webs formed on the second hinge part and can be locked in various angular positions of its locking recess.

[0002] Such hinges, which can be used, for example, for furniture doors or a glass shower enclosure door, are known from DE 10 2005 025 278 B3 and EP 3 741 944 A1. With the aid of the adjustable detent device, the closed position of the door attached to the hinge can be set by adjusting the locking element, which is arranged coaxially to the pivot axis between the two hinge webs of the second hinge part, with its detent recess, so that the door assumes the desired angular position when the locking element is pressed into the detent recess by the spring element.

[0003] To prevent the door or hinge from unintentionally changing its locked position, it is necessary to reliably lock the locking element in its correct angular position on the second hinge section. In the current state of the art, this is achieved by dividing the two hinge webs on the second hinge section in a plane parallel to the pivot axis. These webs comprise a first clamping jaw fixed to the second hinge section and a second clamping jaw attached to a detachable clamping element. These clamping jaws can be adjusted relative to each other by means of a screw connection and, if necessary, a detent mechanism. The clamping jaws clamp the end sections of the locking element between them, thus securing its position relative to the second hinge section and consequently the desired angular position of the detent recess.

[0004] The assembly of the individual components into the finished hinge presents problems with the known hinge designs, particularly the installation of the locking mechanism and its adjustment to the correct angle. This is because installation, and especially the adjustment of the closed position (zero position), can only be achieved if the clamping jaws, by sufficiently loosening the screws, release the intermediate end sections of the locking mechanism enough to allow it to be adjusted to the desired position relative to the second hinge section. Precise adjustment is very difficult to achieve, especially if the adjustment process is to be carried out with the hinge already installed and the door attached.The weight of the door causes the locking mechanism to not maintain its coaxial positioning to the pivot axis during the adjustment process, but instead to be subjected to a relatively large force perpendicular to the direction of the pivot axis during the assembly and / or adjustment process, which makes precise work more difficult.

[0005] The object of the invention is to avoid these disadvantages and to facilitate the assembly and adjustment of the joint band.

[0006] This problem is solved by the invention in that the second band part is at least partially divided / divisible transversely to the pivot axis and comprises a first web part having one of the two band webs and a second web part having the other of the two band webs, wherein the two web parts are detachably connectable / connected to each other by means of at least one connecting element.

[0007] The invention thus departs from the prior art approach with two-part band sections divided in a plane parallel to the pivot axis. Instead, in the invention, the second band section is divided in a plane that runs transversely or perpendicularly to the pivot axis. In an advantageous embodiment, the locking element can have a central section with the locking recess(s) and two pivot pins, preferably reduced in cross-section, arranged at opposite end faces of the central section and fixed relative to it in a rotationally fixed manner. These pivot pins are fixed to the band sections of the second band section in the assembled state.The band webs can be designed to be completely closed by means of the division of the second band section proposed according to the invention in a division direction or plane transverse to the pivot axis, for example by forming circumferentially closed ring receptacles into which the pivot pins of the locking element engage. The mounting of the locking element is also easily possible with closed band webs according to the invention. For this purpose, the two initially separated web sections with the band webs formed on them can be mounted at the two ends of the locking element by attaching them in the direction of the pivot axis, so that the two band webs enclose the pivot pins or the like formed at the ends of the locking element.Subsequently, the two bridge parts are firmly connected to each other using the connecting element provided for this purpose, which is preferably formed by at least one screw connection acting between the two bridge parts, whereby this connection does not need to be loosened during the subsequent adjustment of the closing element to the desired angular position.

[0008] In an advantageous embodiment of the invention, the second band section can comprise a locking element that covers the two web sections in the area of ​​their division plane and is connected to them, preferably screwed, when the web sections are connected. The arrangement of the locking element relieves the load on the connecting element acting between the web sections, in the preferred embodiment the provided screw connection, and ensures that the connection between the web sections cannot unintentionally loosen.

[0009] To fix the desired rotational position of the locking element mounted on the hinge pins, various measures can be provided. For example, in a preferred embodiment of the invention, the locking element can be locked in a rotationally fixed position by means of anti-rotation elements provided on the hinge pins. These anti-rotation elements are particularly preferably clamping screws, e.g., set screws, which penetrate the hinge pins transversely and can be adjusted against the locking element mounted thereon or its pivot pin.

[0010] It is advantageous if the two bridge sections are equipped with interacting positive-locking guides. This ensures, in a particularly simple manner, that during assembly of the hinge band, the two bridge sections are connected with the band webs precisely aligned to each other, so that the locking element is mounted exactly coaxially to the pivot axis between the two band webs.

[0011] The locking device can have a housing that movably receives the locking element transversely to the pivot axis and is rotatably mounted about the central section of the locking body. In an advantageous embodiment of the invention, the locking element can be provided on its front face facing the locking body with at least one rotatably mounted pressure roller, which interacts with the locking recess formed on the locking body to engage it.

[0012] Further features and advantages of the invention will become apparent from the following description and the drawing, in which a preferred embodiment of the invention is explained in more detail by way of an example. It shows: Fig. 1 a hinge according to the invention in a perspective view; Fig. 2 the subject of the Fig. 1 in horizontal section; Fig. 3 the subject of the Fig. 1 and 2 in a vertical section through the second part of the band; Fig. 4 the ligament after the Fig. 1 bis 3 in a first perspective, exploded view of its individual components from a first viewing direction; and Fig. 5 The ligament in a second exploded view from a different perspective.

[0013] The hinge 10, as a whole designated by , serves as a hinge fitting for a glass door that is attached to a wall (not shown). The hinge 10 has a first hinge part 11 and a second hinge part 12, which are pivotally connected to each other about a pivot axis 13. While the first hinge part 11 is provided with a mounting plate 14 having two elongated holes 15 with which it can be screwed to the wall, the second hinge part 12 has two clamping jaws 16 between which the glass door to be held is clamped, as is known, for example, for the door of a shower enclosure.

[0014] The hinge 10 is equipped with a detent device, designated 17, which has a locking element 18 associated with the first hinge section 11. The locking element 18 is housed in a housing 20 that is attached to the mounting plate 14 by screws 19. The locking element 18 is movable in the housing 20 transversely to the pivot axis 13. It is pre-tensioned by two compression springs 21, which engage in spring receptacles 22 in the locking element 18 and press against the rear side of the locking element 18 facing away from the pivot axis. The ends of the springs protruding from the spring receptacles bear against the mounting plate 14. For this purpose, the mounting plate 14 is provided with two short blind holes 23, which, when the housing 20 is mounted, are aligned coaxially with the spring receptacles 22 in the locking element 18 and, together with these, ensure that the compression springs 21 cannot buckle laterally.

[0015] The locking element 18 is provided on its front face 24, which faces the pivot axis 13, with two rotatably mounted pressure rollers 25. These rollers interact with a locking element 26 associated with the second hinge part 12, which is mounted coaxially to the pivot axis 13 on the second hinge part 12 as part of the detent device 17. The locking element 26 has a central section 27 with two ring-shaped shoulders 28 whose height is adapted to the position of the pressure rollers 25. Each shoulder has a detent recess 29 in the form of a concave indentation into which the pressure rollers 25 on the locking element 18 can engage to position the door in its rest position. The housing 20, with the locking element 18 slidably mounted therein, is rotatably mounted about the central section 27 of the locking element 26. The locking element 26 has a pivot pin 30 at each of its upper and lower ends, by which it is fixed to the second hinge part 12.According to the invention, the second band section 12 is divided / divisible transversely to the pivot axis 13, i.e., in the exemplary embodiment, in a horizontal direction or plane E. Thus, the second band section 12 comprises a first web section 31 with a first band web 32 and a second web section 33 with a second band web 34. The two band webs 32 and 34 are designed as circumferentially closed ring receptacles 35 into which the pivot pins 29 of the locking element 26 engage with very little play.

[0016] How to find out especially in the Fig.4 and 5As can be clearly seen, the two bridge sections 31, 33 can be detachably connected to each other by means of screw connections. In the illustrated embodiment, the arrangement is such that a cylinder head screw 36 can be screwed through a hole provided parallel to the pivot axis 13 in one of the two bridge sections into a corresponding threaded bore 37 provided in the other bridge section to connect the two bridge sections. Interacting positive locking guides in the form of a groove 38 and tongue 39 are provided on the contact surfaces of the two bridge sections 31, 33, which ensure precise positioning of the two parts relative to each other.The assembly of the locking element 26, together with the housing 20 mounted on it and the locking element 18 contained therein, on the second hinge section 12 can be easily accomplished with separate web sections 31, 33 by inserting the pivot pins 30 from the inside into the corresponding, ring-shaped hinge webs 32, 34. The two web sections 31, 33 can then be screwed together with the two cylinder head screws 36. The locking element 26 is then hinged to the hinge webs 32, 34 with virtually no play and can be continuously adjusted to the desired position by rotating it about the pivot axis 13, in which the rest position or zero position between the two hinge sections 11, 12 is reached.In this desired position, the locking body 26 is then secured against rotation by means of grub screws 40, which for this purpose pass transversely through the band webs 32, 34 in threaded bores 41 and can be adjusted against the pivot pins 29 of the locking body 26 which are mounted in the ring receptacles 35 and clamp it firmly against the band webs.

[0017] To secure the two web parts 31, 33 against each other and, in particular, to relieve the screws 36 that screw them together, the second band part 12 is provided with a securing element 42 that covers the two web parts 31, 33 in the area of ​​their division plane E, and which, in the connected state of the web parts 31, 33, is screwed to them with a total of four countersunk screws 43, with each pair of these screws 43 being inserted into corresponding threaded bores 44 o are screwed into the upper of the two bridge parts 31 and 44u on the lower bridge part 33.

[0018] The invention makes it possible to adjust the rest position / zero position of the hinge or the door it supports in a particularly simple manner, without inaccuracies or difficulties arising from excessive play between the hinge webs of the second hinge part and the locking mechanism it holds. Readjusting the desired position is easily accomplished by simply loosening and then retightening the grub screws, which are easily accessible from the side.
