Definitions

  • the invention relates to a hinge, preferably a furniture hinge, with a hinge arm which can be fixed to the body and is connected to a pivotable hinge part by means of an articulated lever, an articulated lever having a projection forming a lever arm in the region of an articulated axis, and having a projection on a bolt, preferably a hinge pin opposite the hinge axis, held and in the closed position exerting a closing pressure on the pivotable hinge part, a resilient or spring-loaded flank of a pressing part on which a support edge or a support region of the projection, which migrates on this when the pivotable hinge part is pivoted, is supported.
  • a hinge of this type known from DE-PS 21 17 828 has an essentially V-shaped leaf spring, the one spring leg of which acts on a lever arm-shaped projection of a handlebar or articulated lever in such a way that this projection is its greatest effective in the closed position Lever arm length, while in the open position, the line of action of the force generated by the spring by the The region of the hinge pin of the hinge runs on which the end of the hinge lever provided with the projection is mounted, so that in the open position essentially no force is transmitted to the hinge system by the closing spring.
  • hinges are increasingly required that have a gentle closing behavior, i.e. that do not strike with greater force even if they are not moved into the closed position by hand.
  • a closing force holding the hinge or the door may only be exerted on the hinges in the region of a small opening angle, for example in the region of an opening angle of 10 degrees.
  • DE-OS 24 08 057 is a modification of the hinge of the type specified at the outset, in which the projection consists of a cam connected to the articulated lever with a control cam which has a concentric curve part corresponding to the open position and a curve part which, as it were, forms a step, with a decreasing radius, to which the closing area has angled free end of the resilient leg of the closing spring slides.
  • This known embodiment of the hinge with closing spring requires an increased production outlay owing to the special design of the cam with cam which is connected to an articulated lever.
  • the projection consists of a plastic block made of plastic and connected to the articulated lever, which is provided with a curved part which is concentric with the articulated axis and which has rounded corner areas in mutually parallel flanks of the block passes.
  • the spring-loaded pivot lever is supported on the control curve of the block, which is rounded off by the concentric curve part, and then has a flank at an obtuse angle to a flank that is curved in the shape of a cylindrical shell, which in the closed position of the hinge after the vertex has been passed between the two Flank pieces abuts on a side flank of the curve block.
  • the known hinge has a relatively complex construction, because not only a specially shaped and additionally to be assembled cam block is provided, but also because the design of the pivot lever is complex because it is provided with two curve-forming flanks.
  • the object of the invention is therefore to provide a hinge of the type specified which, with a simple structure, has a closing characteristic, according to which essentially no forces are transmitted to the joint system in the opening region of the hinge, and according to which only in the closing region, which one corresponds to the small opening angle of the door, closing forces are exerted.
  • this object is achieved with a hinge of the generic type in that the projection is supported in the closed position on an essentially straight region of the flank, which merges approximately tangentially to the free end of the flank into an arcuately curved region, the radius of which essentially corresponds to the distance of the support edge of the projection from the hinge axis, and that the projection is supported after a slight opening movement of the pivotable hinge part on the arcuate region of the flank which is essentially concentric with the hinge axis.
  • the desired closing characteristic is achieved without a special control cam attached to an articulated lever, but solely through a projection of a handlebar, which can consist of a tongue bent out of this, and an arcuately curved configuration of a resilient leg.
  • the invention Hinge is therefore characterized by a particularly simple structure that enables it to be manufactured economically.
  • the projection connected with an articulated lever or bent out of it requires only little space in the hinge arm and the supporting edge or the supporting region of the projection can be easily adapted to the desired closing characteristic.
  • the resilient flank expediently consists of one leg of an essentially bow-shaped spring or leg spring, the other leg of which is supported on one of the hinge parts. Since the cooperating with the projection leg of the leaf spring has a curvature, the axis of curvature after a short distance of the support edge from its closed position in the opening direction is concentric with the hinge axis about which the projection can be pivoted, and since the tension state of the spring over the further path of the Door remains unchanged in the open position, the spring is only stressed by a simple bending tension with small changes in tension, so that the life of the spring is extended.
  • the resilient flank is formed by a pivotably mounted lever on which one leg of an essentially bow-shaped spring or leg spring supported on the hinge pin is supported, the other leg of which is supported on one of the hinge parts.
  • the lever which is mounted on a pin, preferably on a hinge pin, has a flank which forms a control cam and consists only of a curved part of the free end of the lever. This simply curved flank area does not interact with a specially shaped cam block, but rather with a projection which is integral with the articulated lever and which can be bent out of it, for example in the form of a tongue.
  • the length of the resilient or spring-loaded flank is expediently chosen so that the same leaf spring or the same lever can be used in different joint systems with opening angles of 90 to 130 degrees and larger opening angles.
  • the curvature of the leaf spring is circular, so that neither an opening nor a closing force is exerted on the joint system from the fully open position of the door until shortly before the closed position, because the supporting edge of the projection sliding on the resilient leg does not pass through a dead center .
  • the closing spring used according to the invention can consist of a leaf spring or else of a leg spring with a central coiled area, the resilient leg or resilient legs of which are curved in the manner described or act on the lever shaped in the manner described.
  • a hinge is known in which a projection provided on an articulated lever cooperates with the flank of a pivotally mounted lever which is on a spring pillow is supported.
  • the flank of the lever is either straight or concave or convex curved, but without this forming a control curve with the characteristic desired according to the invention.
  • the hinge arm 1 bent from a corresponding sheet metal blank and of which only its front part is shown is fastened in the usual way to a body part, for example a cabinet wall 2.
  • a body part for example a cabinet wall 2.
  • articulation pins 4, 5 are held, on which the one ends of articulated levers 7, 8 are pivotably mounted.
  • the other ends of the articulated levers 7, 8 are pivotally mounted on articulated bolts 9, 10 which are fastened to the wall of the pot-shaped hinge part 11.
  • the hinge pins 4, 5 and 9, 10 form the corner points of a trapezoid.
  • the hinge pin 5 is fastened between the extended tabs of the legs 3 of the hinge arm 1 so that it can dip into the cup-shaped hinge part 11 in the closed position.
  • the cup-shaped hinge part 11 is connected to a door 12, for example.
  • the articulated lever 7 consists of a sheet metal part which is U-shaped in cross section, while the articulated lever consists of an angled sheet metal strip, the ends of which are rolled up to form eyes which receive the bolts 4, 10.
  • the hinge joint has a customary structure, so that no further description is required.
  • a tongue 14 is bent out of the articulated lever 8 in the area of the eye 13 enclosing the articulated pin 4, which tongue forms a projection and thereby turns the articulated lever 8 into a two-armed lever.
  • a bow-shaped spring 16 is held between the angled legs of the hinge lever 7 with the interposition of a pipe section 15 made of plastic.
  • This bow-shaped spring 16, with its arcuate part 19 connecting the legs 17, 18, also carries the hinge pin 5 or the tube piece 15 pushed onto it a circumferential angle that is slightly larger than 180 degrees, so that the bow-shaped spring 16 is fixed on the hinge pin 15.
  • the shorter leg 17 of the bow-shaped spring 16 lies in the manner shown in FIGS. 1 and 2 on the central web part of the hinge arm 1.
  • the tongue-like projection 14 is supported on the resilient leg 18 of the bow-shaped spring 16.
  • the resilient leg 18 has a straight section 20 which opens tangentially into the arcuate end section 21.
  • the radius of the arcuate or cylindrical shell-shaped end region 21 of the resilient leg 20 corresponds, as can be seen from FIG. 2, to the distance r from the hinge axis of the hinge pin 4 to the support edge 23 of the tongue-like projection 14.
  • the support edge 23 is supported on the straight portion of the resilient leg 18 of the bow-shaped spring 16, so that the spring 16 acts on the hinge in the closing direction with the effective lever arm length a.
  • the support edge 23 of the projection 14 migrates to the arcuate section 21 of the resilient leg 20, the axis of curvature of which coincides with the axis of the pivot pin 4, so that the component from the Spring force always runs through the hinge pin 4 and the spring 16 acts neither on the hinge in the opening nor in the closing direction.
  • the radius of curvature of the curved section 21 can increase toward the end of the resilient leg 20.
  • FIGS. 4 to 8 A second exemplary embodiment is now based on FIGS. 4 to 8 explained.
  • This second embodiment differs from that according to FIGS. 1 to 3 essentially in that it is not a leg of the spring that forms the control cam, but a correspondingly shaped pivot lever loaded by one leg of the spring.
  • the pivot lever 115 is freely pivotably mounted on the pivot pin 5 between the angled legs of the pivot lever 7.
  • the pivot lever 115 consists of a U-shaped sheet metal blank, the angled legs 116 of which are provided with bearing bores 117.
  • the web part of the articulated lever 115 consists of a straight section 118, which is for the most part between the legs 116, and a curved section 119 adjoining this towards the free end.
  • a V-shaped leaf spring 120 is held with the interposition of a plastic tube, one leg 121 of which is supported on the web part of the hinge arm 1 and the other leg 122 of which is supported on the web part of the pivot lever 115.
  • the arcuate part 123 of the V-shaped leaf spring 120 connecting the legs 121, 122 frames the hinge axis 5 for holding the spring over a circumferential angle which is somewhat larger than 180 degrees.
  • the pivot lever 115 loaded by the resilient leg 122 is supported with its web part on the tongue-like projection 14.
  • the straight section 118 of the pivot lever 115 opens tangentially into the arcuate end section 119.
  • the radius of the arcuate or cylindrical shell-shaped end region 119 of the pivot lever 115 corresponds, as can be seen from FIG. 5, to the distance r between the hinge axis of the hinge pin 4 and the support edge 125 of the tongue-like projection 14.
  • the support edge 125 is supported on the straight section 118 of the pivoting lever 115, so that the pivoting lever 115 acts on the hinge in the closing direction with the effective lever arm length a.
  • the support edge 125 of the projection 14 migrates onto the arcuate section 119 of the pivot lever 115, the axis of curvature of which coincides with the axis of the hinge pin 4, so that the component from the spring force always runs through the hinge pin 4 and the spring-loaded pivoting lever 115 acts neither on the hinge in the opening nor in the closing direction.
  • the radius of curvature of the curved section 119 can increase toward the end of the pivot lever 115.
  • the pivot lever can also be acted upon by a leg spring with a central coiled area of the type shown in FIG. 7.
