Definitions

  • the invention relates to a hinge arm with a mounting plate, some of which are provided with a spring-loaded pivotable lever and the other with an abutment gripped by the lever, which after inserting the hinge arm into a guide of the mounting plate and moving in the longitudinal direction into its lower detachable, together snap locked position, and with a stop that limits the displacement when or after snapping the interlocking parts.
  • the latching is effected by a lever provided with a latching projection which engages in a latching opening of the opposite in such a way that a wedge-shaped flank of the latching projection engages with it in a self-tensioning manner, so that the hinge arm is held free of play at the stop of the mounting plate.
  • the known snap connection enables quick and easy assembly of hinge joints in that the hinge arm only needs to be pushed onto the preassembled mounting plate. Since the flank of the spring-loaded locking projection constantly exerts a push on the edge region of the locking opening, the fastening plate and the hinge arm are clamped together without play.
  • this known snap connection for fastening the hinge arm to the fastening plate is relatively complex and a good self-tightening effect is only achieved if the locking lever is acted upon by a relatively strong spring.
  • the object of the invention is therefore to constructively simplify the known hinge arm with improved self-tensioning effect.
  • this object is achieved by the characterizing features of patent claim 1.
  • the hinge arm according to the invention its locking with the fastening plate is achieved in a simple manner in that the latching lever and the abutment are supported on one another at an angle or at right angles to the latching flank and the latching lever is subjected to pressure in such a way that the pull on the hinge arm Locking lever engages the abutment with greater locking force.
  • the locking effect is essentially caused only by the frictional force exerted by the lever or the abutment on the locking surface, so that the spring loading the lever can be made very weak, since it only needs to pivot the locking lever against the abutment when loosening or there should be a game between the two.
  • the latching flank can be formed on the lever or else on the abutment, while the other part has the support edge or support surface.
  • the support of the support edge or support surface on the latching flank is expediently located between the hinge pin of the lever and the front end of the hinge arm provided with the bearing bores.
  • the required support force can also be achieved by the gravity of the lever, which is supported by the spring force.
  • the hinge arm expediently consists of a U-shaped sheet metal stamped part, the lever being mounted in its end region on a bearing pin fastened between its legs.
  • the hinge arm is locked in its end region with the fastening plate, so that a stable fastening is ensured due to the large effective lever arm of the hinge arm.
  • the latching flank can be provided both on the hinge arm and on the fastening plate. However, a simpler construction results if the latching flank is provided at the rear end of the fastening plate.
  • the guide for webs bent from the legs of the hinge arm can be provided between a base plate with an attached holding block and the edges of the legs directed against the base plate of a U-shaped cover plate screwed onto the base plate, both of which form the fastening plate.
  • the latching flanks are expediently provided on the rear end regions of the legs of the cover plate.
  • the lever consists of a U-shaped sheet metal part, the legs of which form locking levers that interact in pairs with the locking flanks.
  • the two-armed lever can be mounted in bores in its legs on the bearing bolt fastened between the legs of the hinge arm, the web part of which forms an opening button located between the cut-out legs.
  • This opening button can be operated easily by hand, since it only needs to be acted upon by a small spring force and, with the depression of the opening button, the hinge arm can also be pushed off the fastening plate.
  • a leaf spring can be clamped between the web part of the hinge arm and the lever and the bearing bolt lying between them, which is preloaded so that it tries to raise the lever arm provided with the web part so that the locking lever is pressed against the flank forming the abutment.
  • the locking lever can be provided at its front end with a cutting-like tip, with which it is supported on the locking flank. This coefficient increases the coefficient of friction, so that the angle of friction also increases.
  • the flank forming the abutment can be inclined relatively flat, so that a locking of the hinge arm with the mounting plate is ensured over a relatively long way.
  • the locking flank is formed by the end face or end faces of the leg or legs of the lever.
  • the abutment can be formed by the rear edge of the web part of the cover plate.
  • the base plate and the cover plate are expediently formed symmetrically to their longitudinal and transverse center lines, so that simple left and right installation is possible.
  • the end regions of the side walls formed by the legs of the cover plate are expediently beveled in order to create wedge-shaped inlet regions for the guides.
  • the base plate 3 is screwed onto the supporting wall 2, which can consist of a cabinet wall or another carcass part, and is provided with fastening holes 4, 5 for its fastening.
  • the rectangular base plate 3 is provided in its central region with a holding block 6, which is extended in an H-shape on both sides by webs 7.
  • the holding block 6 with the webs 7 that extend this forms a cross-sectionally rectangular holding and guiding part for a cover plate 8 screwed onto it.
  • the cover plate 8 consists of a U-shaped sheet metal, the web part of which has an elongated hole 9 and at its front end an outwardly open slot 10 is provided.
  • the cover plate 8 is screwed to the base plate 3 by a holding screw 11, which is screwed into a threaded bore 12 of the holding block 6, in such a way that the legs 13, 14 of the cover plate 8 overlap the guide part formed by the holding block 6 and the webs 7 .
  • the elongated hole 9 enables a longitudinal displacement of the cover plate and thus also of the hinge arm relative to the base plate 3.
  • the lower edges of the legs 13, 14 of the cover plate 8 screwed onto the base plate 3 end at such a distance above the lateral regions of the base plate 3 that 7 guide grooves 15 are formed on both sides of the webs for webs 16 of the hinge arm, which are formed by the legs 17 of the Hinge arms 1 are angled inwards.
  • the legs 13, 14 of the cover plate are provided in their rear end regions with extensions 18, 19 which abut the base plate 3 and thus form stops in the manner shown in FIG. 1 for the webs 16 inserted into the guide grooves 15.
  • the legs 17 of the hinge arm are provided with bores 20, 21 for bearing bolts of the hinge joint.
  • a bearing pin 22, on which the locking lever 23 is mounted, is fastened in the rear region of the hinge arm 1 between the legs 17.
  • the locking lever 23 is U-shaped in the manner shown in FIGS. 1, 2 and 4.
  • the legs 25, 26, which form the latching levers and are provided with support edges 34 at their lower free ends, are angled away from the web part 24, which forms an opening button.
  • the locking lever 23 is mounted in holes in its legs on the bearing pin 22, so that it is formed with two arms.
  • a leaf spring 27 is supported on the bearing axis 22, the ends of which rest against the web parts of the locking lever 23 and the hinge arm 1 with prestress.
  • the web part of the hinge arm 1 is further provided with a window 28 in order to be able to reach the fastening screw 11 and with a flared threaded hole for the set screw 29.
  • the adjusting screw 29 is in its lower area provided an annular groove 30 which engages in the elongated hole 10.
  • the legs 13, 14 of the cover plate 8 are provided in their rear area on the side opposite the extensions 18, 19 with latching flanks 31. These locking flanks are shown in an enlarged form in FIG. 5. As long as the friction angle a, which results from the angle between the connecting line of the support edge 34 with the center line of the bearing pin 22 and the normal to the locking flank 31, is smaller than the friction angle, the locking lever is securely engaged on the locking flank and thus a locking guaranteed of the hinge arm with the mounting plate.
  • the legs 13, 14 cut free from the web portion of the cover plate 8 are approximately raised in their rear area, so that when the hinge arm 1 is pushed on, the legs 25, 26 of the locking lever 23 run over the hump 32 formed thereby and fall into their latching position with an improved snap effect can.
  • the base plate 3 is provided in the area to the side next to the webs 7 with ramps 33 which rise outwards in a wedge shape and which, when the hinge arm 1 is pushed on, additionally press the webs 16 which are angled inward from its legs 17 against the lower edges of the legs 13, 14 of the cover plate 8 .
  • the wedge-shaped ramps 33 are arranged in mirror image to the transverse axis of the base plate 3 in order to be able to mount the hinge arm pointing to the left as well as to the right. So that when the hinge arm is pushed on, the front ramps 33 in the pushing-on direction do not impede the pushing on, the legs 13, 14 of the cover plate are lower in the front area in the manner shown in FIG. 1.
  • the legs 13, 14 of the base plate 8 are extended towards the front, rounded and bent inwards.
  • the legs 41 of the latching lever 43 pivotally mounted at the rear end of the hinge arm 40 about the pivot pin 42 are provided on their outer end faces with curved curved flanks 44 which are eccentric to the latching pin 42.
  • the latching flanks 44 are designed eccentrically in such a way that, in a side view, they move upwards approximately spirally from the central axis of the hinge pin 42.
  • the locking lever 43 is acted upon by the S-shaped leaf spring 45, which it tries to pivot clockwise in FIG. 7.
  • the leaf spring 44 is supported in its central region on the hinge pin 42 and with its end regions on the web parts of the hinge arm 40 and the locking lever 43.
  • the Ste part 46 of the locking lever 43 also forms the opening button.
  • the intermediate or cover plate 47 is U-shaped in cross-section and has a central elongated hole 48 for the fastening screw 49 and elongated holes 49, 50 which are open at the ends thereof, in which the annular groove 52 can be seen in FIG. 7 the set screw 51 engages.
