Definitions

  • the invention relates to furniture hinges with a locking or locking device, consisting of a spring element which acts on at least one articulated lever which connects the hinge parts to one another in an articulated manner or on a latching member (latching nose, latching lever) accommodated in one of the hinge parts and at least shortly before reaching the When the hinge is in the closed position, a force component acting in the closing direction of the hinge is produced, adjustment means acting on the spring element being present in order to be able to change the strength of the spring force.
  • Such hinges with variable closing or locking force are known.
  • the changeable closing or locking force should enable the closing behavior to be adapted to special customer requirements or different door weights and / or door sizes.
  • the disadvantage here is that it is difficult or impossible to identify the degree of spring preload from the screw position alone.
  • the spring element is a leaf spring, one end of which lies in a tooth gap of a notch-like toothed rack.
  • the end of the leaf spring must be brought into an adjacent gap in the rack, either to increase or decrease the curvature of the spring.
  • the invention has for its object to provide an acting on the spring element of a furniture hinge with locking or locking device adjusting that is easy and quick to operate, the degree of spring bias can be recognized at any time and with little space required for different trained spring elements or spring systems and / or hinge types can be used.
  • the adjusting means is a threadless, axially immovable, rotatably mounted molded body, which acts directly or indirectly on the spring element during rotation and changes the position of the entire spring element or the position of at least one leg of the spring element.
  • the molded body is mounted in the hinge arm on the furniture side and has at least one eccentric projection which, with its end face or circumferential surface, interacts directly or indirectly with the spring element - or a part thereof.
  • the molded body is mounted in the yoke of the U-shaped hinge arm and has an actuating part accessible from the outside and an eccentric extension projecting into the interior of the hinge arm, which engages in an elongated hole of a flat sliding piece lying on the yoke of the hinge arm, which lies with one end under one leg of the spring element.
  • the setting can be carried out quickly and easily - even by the end user - and the entire facility takes up little space and can be used for differently shaped spring elements (leaf springs, leg springs, coil springs) and different locking and locking systems, for example, even if the locking or guard locking device is housed in the door-side hinge part (hinge cup) or in the furniture-side hinge part (hinge arm).
  • the hinge shown in the partial representation corresponding to FIG. 1 is a known furniture hinge, consisting of a hinge part to be fastened on the furniture side, the hinge arm 1 and the hinge part, not shown, to be fastened on the door side, the hinge cup.
  • Hinge arm 1 and hinge cup are articulated to one another in a known, unspecified manner by two articulated levers 2, 3.
  • the hinge lever 3 fastened to the hinge arm 1 with the hinge pin 6 has a cam-like elevation 8 on its back 7.
  • In the yoke 9 of U-shaped design Hinge arm 1 is an adjusting member 10 with a cylindrical projection 11 in a recess 12 of the hinge arm 1 rotatably mounted.
  • the adjusting member 10 has an outer actuating part 13, with a screwdriver slot 14 or the like, and an eccentric pin 16, which projects into the interior 15 of the hinge arm 1 and penetrates an elongated hole 17 of a slide piece 18.
  • a washer 35 riveted to the eccentric pin 16 holds the described arrangement together.
  • the sliding piece 18 has approximately the width of the hinge arm interior 15 and is guided laterally through the side flanks 19 of the hinge arm 1.
  • the sliding piece 18 carries an inclined surface 21.
  • the first leg 22 of the leg spring 5 lies on this inclined surface 21.
  • the end 23 of the leg 22 can be angled.
  • the second leg 24 of the leg spring 5 is supported on the cam-like elevation 8 of the articulated lever 3.
  • the hinge shown in Fig. 1 is in the closed position.
  • the leg spring 5 acting with the leg 24 on the cam 8 of the articulated lever 3 generates a force component in a known, not to be described manner, which presses the hinge on the last part of the closing movement into the closed position and holds it there.
  • the adjusting member 10 is rotated, for example, with a screwdriver or the like which extends into the screwdriver slot 14.
  • the eccentric pin 16 which engages in the elongated hole 17 of the sliding piece 18 moves the sliding piece 18 towards or away from the leg spring 5.
  • the inclined surface 21 presses the first leg 22 - in the sense of increasing the spring preload - towards the second leg 24.
  • An increase in the spring preload leads to an increase in the force component acting in the closing direction of the hinge.
  • noses, grooves or grooves 25 which produce a positive connection can be provided on the sliding piece 18 and on the yoke 9 of the hinge arm 1.
  • These grooves 25 can, however, also be arranged on the inclined surface 21. In this case, it can be useful to design the kink 26 of the angled end 23 of the leg spring 5 so that it has a sharp nose.
  • a spring washer (not shown) accommodated between the parts can provide the necessary contact pressure or positive locking between the grooves, grooves 25.
  • the degree of the change in position or the adjustment of the leg 22 can, if necessary, be influenced by changing the angle of the inclined surface 21 in the sense of an enlargement or reduction.
  • a marking can be made on the actuating part 13 and a scale can be placed on the top of the hinge arm 1 in the area of the actuating part 13 (for example with numbers 1 to 10). or another orientation aid with corresponding symbols, markings or the like.
  • the start and end positions can be defined by stops, i.e. the max.
  • the adjustment path is then less than 360 °.
  • the spring element need not be exclusively a wire leg spring 5;
  • a leaf spring or helical spring can also be used with the described adjustment principle, provided that the spatial conditions or special design allow it.
  • the adjustment principle described can also be applied to so-called single-joint hinges, i.e. for hinges that do not have two articulated levers or for so-called wide-angle hinges with several articulated levers that allow an opening angle of approx. 180 °.
  • FIG. 3 shows a further very simple, possible embodiment of an adjusting member 10a with a cylindrical basic shape and on the end faces 28 eccentrically attached bearing journals 29 with screwdriver slots 14a for screwdrivers or the like.
  • the adjusting member 10a is also provided with lugs, grooves, Grooves 25a are provided in order to produce a locking action in cooperation with the first leg 22 and the kink 26.
  • the adjusting member 10a is mounted with its eccentrically attached bearing journals 29 in the side flanks 19 of the hinge arm 1 in correspondingly provided recesses, not shown.
  • the correspondingly long leg 22 of the leg spring 5 lies on the peripheral surface 30.
  • the sleeve-shaped body 31 carries on the face rising or falling surfaces / curves 32, which can be provided with grooves, grooves 25b in order to produce a locking effect in cooperation with the correspondingly long leg 22.
  • the surfaces / curves 32 could have different courses or different inclinations / slopes in order to be able to cover different applications.
  • FIG. 5 also shows a sleeve-shaped adjustment part 33 of the adjustment element 10, but the slots rising / falling on the circumference 34 shows, which can also alternatively have different inclinations / slopes if different spring travel or force components are desired.
  • the correspondingly long leg 22 engages in one of the selected slots 34 and - depending on the direction of rotation - is moved towards the second leg 24 or removed therefrom.
  • the slots 34 can also be provided with grooves or grooves to produce a locking effect.
  • the embodiment according to FIG. 6 shows that it is also conceivable to move the entire spring element 5a with the adjusting member 10.
  • the length of the effective spring leg changes, based on the point of application A, and the spring 5a is displaced when the spring 5a is moved Hinge pin 4,5 towards a shortening of the effective spring leg and thus to a strengthening of the force component and a displacement of the spring 5a in the sense of an extension of the effective spring leg 5a to a weakening of the force component.
