Definitions

• the invention relates to a hinge, in particular for glass doors, with two hinge parts which are connected to one another in an articulated manner about a pivot axis of an axle bolt, and with a locking device which acts between the two hinge parts and which essentially consists of at least one locking element which is assigned to the first hinge part and is guided so as to be movable against the action of at least one spring element, and a closing body which is assigned to the second hinge part and has at least one locking surface which interacts with the locking element in a locking position, wherein the closing body is arranged between two hinge webs formed on the second hinge part coaxially to the pivot axis and can be locked in various angular positions of its locking surface.
• Such hinges which can be used for furniture doors or even a glass door of a shower enclosure, are made from DE 10 2005 025 278 B3 and the EP 3 741 944 A1 known.
• the closed position of the door hinged to the hinge can be adjusted by adjusting the locking body, which is arranged coaxially to the pivot axis between the two hinge webs of the second hinge part, with its locking surface so that the door assumes the desired angular position when the locking element is pressed against the locking surface by the spring element.
• the two hinge webs on the second hinge part being divided in a plane parallel to the pivot axis and comprising a first clamping jaw fixed to the second hinge part and a second clamping jaw formed on a detachable clamping means part, which are mutually secured by means of a screw connection and, if necessary, a locking mechanism.
• the clamping jaws clamp end sections of the locking body between them, thus securing its position relative to the second hinge part and thus the desired angular position of the locking recess.
• the object of the invention is to avoid these disadvantages and to design a hinge of the generic type in such a way that it can be assembled and adjusted more easily than known designs and that the adjustment found is then reliably maintained.
• the locking body is formed by the axle bolt, which forms a bearing receptacle for the first hinge part between a first axle bolt end and a second axle bolt end, on the circumference of which the locking surface is formed, wherein the first axle bolt end is rotatably engaged in a first axle receptacle arranged on the first hinge web of the second hinge part and the second axle bolt end is rotatably engaged in a second axle receptacle arranged on the second hinge web of the second hinge part, wherein at least one of the axle bolt ends is provided with a threaded bore arranged transversely to the pivot axis and a clamping screw screwed into this for clamping the axle bolt end in the associated axle receptacle. which is adjustable from an outer side of the second band part in the threaded hole.
• the adjustment and locking of the locking body relative to the second hinge part in various angular positions can be achieved very easily and quickly by adjusting the clamping screw, which is accommodated transversely to the pivot axis in the threaded hole in the axle pin end, from the outside of the hinge part in such a way that the axle pin end clamps inside the axle receptacle that receives it, thus preventing any initial rotational mobility.
• the axle pin forming the locking body can rotate with its axle pin ends essentially freely in the axle receptacles.
• the second hinge part can be adjusted to the desired position relative to the locking body (and thus also relative to the first hinge part). If the clamping screw is then screwed into the threaded hole from the outside of the second hinge part, this creates a radially directed clamping force acting between the wall of the axle mount and the axle pin end, which then prevents relative rotation between the second hinge part and the locking body and thus ensures that the previously set position of the locking surface is fixed relative to the second hinge part.
• the design according to the invention not only allows the desired position of the locking body to be easily adjusted, but the screw connection transverse to the pivot axis makes it possible to achieve a high clamping force between the axle pin end and the axle mount that accommodates it, so that subsequent unintentional adjustment of the position once achieved is largely ruled out. Nevertheless, readjustment is possible at any time without problems thanks to the easy accessibility of the clamping screw from the outside of the hinge part, and in particular without the complex disassembly of the (door) element held by the hinge.
• the at least one axle pin end is designed to be slotted parallel to the pivot axis over at least part of its length and forms two clamping jaws that can be spread radially outwards relative to each other by means of the clamping screw.
• the arrangement can also be such that the both clamping jaws are designed with different thicknesses, i.e. one of the two clamping jaws has a stronger cross-section than the other of the two clamping jaws. Since the clamping jaws can be adapted on the outside to the circular cylindrical contour of the axle mount, the preferred design enables high spreading forces caused by the clamping screw between the two clamping jaws to be achieved with comparatively low surface pressure between the clamped parts.
• the arrangement can be such that the threaded hole and the clamping screw that can be screwed into it are provided in only one of the two clamping jaws; in the case of asymmetrical (i.e. different cross-sections) design of the clamping jaws, preferably in the stronger clamping jaw.
• the clamping screw can be a grub screw that can be fully screwed into the threaded hole, preferably with a continuous thread along its length.
• a grub screw without a screw head that protrudes radially beyond the diameter of the thread, can be fully screwed into the threaded hole and thus does not protrude from the threaded hole laterally. This would not only represent a visual disadvantage in the design of the hinge, but could also negatively affect the relative mobility between the hinge part and the locking body.
• the clamping screw can have a front clamping point whose diameter is smaller than the effective thread diameter of the clamping screw or the threaded hole.
• the clamping point can be pressed against the inside of one
• the clamping jaw (especially the one with the smaller cross-section) or the one with the smaller cross-section can be positioned directly against the wall of the axle mount. It is possible that - in the design with two clamping jaws - the front clamping tip of the screw engages in a centering guide provided on the inside of one of the two clamping jaws, facing the other clamping jaw with the threaded hole.
• both axle pin ends are provided with threaded holes arranged transversely to the pivot axis and with clamping screws screwed into these holes to clamp the respective axle pin end in the corresponding axle mount.
• the locking action thus occurs on both sides of the locking surface located between them, thus avoiding torsional loading of the locking element when the hinge is opened and the locking element is moved from its locking position on the locking surface.
• the second hinge part is preferably provided with at least one access opening to the axle bolt end provided with the threaded hole and the clamping screw received therein.
• a suitable tool e.g., an external hexagon or a hexalobular socket wrench.
• the access opening is preferably designed as an elongated hole aligned transversely to the pivot axis, so that the tool holder formed on the clamping screw, for example, a hexagon socket or hexalobular socket, is easily accessible in various angular positions of the locking body.
• the access opening can advantageously be closable or closed by means of a cover, so that it is only visible when the cover is removed or opened for adjustment work.
• the locking surface on the locking body is preferably aligned at least substantially parallel to the axis of rotation of the clamping screw(s).
• a glass shower door can be pivotally mounted on a wall according to the preferred embodiments shown.
• the invention is not limited to this application.
• the hinge 10 essentially consists of a first hinge part 11, which can be screwed to a wall by means of a perforated mounting plate, and a second hinge part 12, which is pivotally connected to the first hinge part 11.
• the second hinge part 12 is provided with a first hinge web 13 and a second hinge web 14 with associated axle supports 15, in which axle supports 17 are provided, drilled coaxially to the pivot axis 16.
• the axle supports 17 each receive a first and second axle pin end 18 and 19 of a between the two belt webs 13, 14 through an axle bolt 20.
• this In its central region, located between the two axle bolt ends 18, 19, this forms a bearing receptacle 21 for a support bracket 22 formed on the first belt part 11, which is provided with a through-bore 23 adapted to the diameter of the axle bolt 20, in which the axle bolt 20 with its bearing receptacle 21 is rotatably received about the pivot axis 16.
• the hinge 10 is equipped with a locking device, designated overall by 24, which has a locking element 25 assigned to the first hinge part 11, which is received in a transverse bore 26 arranged transversely to the pivot axis 16 in the support bracket 22.
• the locking element 25 is movable in the support bracket 22 transversely to the pivot axis 16. It is preloaded by a compression spring 27, which engages in a spring receptacle 28 open at the rear in the locking element 25 and presses there against the rear of the locking element 25 facing away from the pivot axis 16. With its rear end protruding from the spring receptacle 28, the spring 27 is supported on a closure cap 29, which closes the rear of the transverse bore 26 in the support bracket 22 of the first hinge part 11.
• the locking device 24 also includes the locking body 30 of the axle bolt 20, which has a flat locking surface 31 milled around the circumference in the area of the bearing support 21 for the support bracket 22, which interacts with the front, likewise flat, end face 32 of the locking element 25.
• the locking surface 31 and the end face 32 of the locking element 25 lie flat against one another under the action of the spring force of the compression spring 27.
• the locking body 30 formed by the axle bolt 20 In order to bring the locking device 24 out of the locking state, the locking body 30 formed by the axle bolt 20 must be rotated about the pivot axis relative to the locking element 25 and thus to the first hinge part 11, wherein one or the other of the two axially parallel edges, at which the flat locking surface 31 borders on the otherwise circular-cylindrical circumferential surface of the axle bolt 20 in the region of the bearing receptacle 21, slides along the end face 32 of the locking element 25 and presses it into the transverse bore against the spring.
• the two axle bolt ends 18, 19, which initially engage in the axle receptacles 17 formed on the hinge webs 14 in a rotationally adjustable manner during assembly of the hinge are provided with threaded holes 33 arranged transversely to the pivot axis 16.
• a clamping screw 34 for clamping the respective axle bolt end 18, 19 is screwed into the threaded holes in such a way that it can be adjusted from an outer side of the second hinge part 12 in the threaded hole 33.
• the second hinge part 12 is designed to be divided in a plane of the glass door to be supported (not shown) and has two clamping plates, of which the first clamping plate 12a has the axle supports 15 with the axle receptacles 17 arranged therein for the axle bolt ends 18, 19.
• the second of the two clamping plates 12b can be clamped to the first clamping plate 12a with a total of four countersunk screws 35 in the exemplary embodiment, wherein the glass shower door (not shown) is then clamped and securely held between the two clamping plates 12a, 12b of the second hinge part 12 with the interposition of several elastic compensating plates 36, as is known to the person skilled in the art.
• elongated holes 37b and 37a are arranged on the second clamping plate 12b thereof, as well as on the axle supports 14 on the first clamping plate 12a, such that the clamping screws screwed into the threaded holes 33 can be reached through these holes with a suitable tool and can be screwed in and out.
• the clamping screws 34 are grub screws that can be screwed fully into the respective threaded hole 33 and have a hexagon socket at the rear head end, which can be reached from the outside through the elongated holes. By inserting a suitable hexagon socket wrench through the elongated holes 37, the clamping screws can be screwed in and out of their threaded holes.
• the axle bolt 20 is designed asymmetrically slotted at its two bolt ends 18, 19 parallel to the pivot axis 16 and forms two clamping jaws 38, 39 of different cross-sections that can be spread radially outwards relative to each other by means of the clamping screw 34.
• the threaded bore 33 is located only in the first of the two clamping jaws 38, which has a has a significantly larger cross-section than the second clamping jaw 39.
• the clamping screw 34 has a front clamping tip 40 whose diameter is smaller than the effective thread diameter of the clamping screw 34 or the threaded bore 33.
• the clamping screw engages in a centering recess 41 provided on the inside of the second clamping jaw 39, so that when the clamping screw 34 is screwed into the threaded bore 33 and the spreading force thereby caused between the two clamping jaws, it is guided and cannot run sideways.
• the clamping jaws 38, 39 which are spread radially outwards relative to one another, press firmly against the cylindrical bores in the axle receptacles 17 and thus clamp the axle bolt ends 18, 19 in a rotationally fixed manner in these, so that the previously set angular position between the closing body 30 and the second hinge part 12 is secured by screwing in the clamping screws 34.
• a cover 42 that can be locked to the clamping plate can be attached to the outside of the second clamping plate 12b, so that the four countersunk screws 35 and also the elongated holes 37 are then no longer visible.
• the axle bolt ends 18, 19 are not slotted and thus not divided into two clamping jaws each as in the first embodiment, but the threaded bore 33 penetrates the one-piece axle bolt end 18, 19 transversely across its entire diameter, so that the screwed-in clamping screw, with its flattened front end here, comes into contact directly with the inner wall 43 of the respective axle receptacle 17 when the clamping screw 34 is screwed into the threaded bore by means of the appropriate tool attached to its rear screw head through the elongated hole 37.
• This also radially clamps the axle bolt end 18, 19 in the associated axle receptacle and thereby locks the locking body 30 in its angular position relative to the second hinge part 12. Access to the clamping screws in various angular positions is ensured by the elongated holes, because the tool holder at the rear end of the clamping screws can be easily reached from various positions using the appropriate socket wrench.
