Definitions

  • the invention relates to a single-axis hinge, in particular for folding doors with several door leaf elements, according to Preamble of claim 1.
  • Single-axis hinges of this type are needed to, for example, at Folding doors the individual door leaf elements like an accordion to be able to lock and open.
  • the invention is therefore based on the object of a single-axis hinge of the type mentioned at the beginning, where symmetrical forces on neighboring door leaf elements are exercised, with the door wings in the extended Keep closed position aligned.
  • a spring acts on both hinge tabs under tension such that this in a closed position Folding door at a mutual angle of 180 ° in a first stable position.
  • Such one Single-axis hinge holds the door leaf elements of a folding door in their extended position, which causes the door leaves to slide in held on a level without e.g. under can move the influence of pressure fluctuations in the room.
  • Such a folding door is therefore kept stable without rattling of the door leaf elements can occur.
  • the spring both hinge tabs in the extended position of the door leaf elements, that is in the closed position of the folding door, against you the angular position the hinge tab to each other at an opening angle of 180 ° restricting stop presses.
  • a such stop serves to prevent the hinge take an opening position beyond 180 ° can.
  • the spring can also open the hinge tab the folding door at a mutual angle of Hinge tabs of approx. 0 ° in a second stable position hold so that the door leaf elements also in their Open position can be held together compactly.
  • the spring exercises an intermediate position between 0 and 180 ° Restoring force on the door leaf elements and relieved the actuation of a folding door towards the End positions.
  • the axis of rotation of the single-axis joint is related to the Swivel range of the hinge flaps on the inside of the Hinge tabs arranged.
  • the arrangement of the axis of rotation on the inside of the hinge tab allows the Hinge tabs and thus the door leaf elements closed by 180 ° swivel.
  • the spring is related to the swivel range of the hinge flaps also on the inside of the hinge tab arranged.
  • a spring arranged in this way is reached their widest spread position at an angle of 90 ° between the hinge tabs.
  • a dead center of the force acting on the hinge lobe achieved because the symmetrical forces of the spring mutually pick up and no torque on the hinge tabs produce.
  • the hinge tabs are pushed apart, while after passing dead center the hinge tabs compressed due to the spring force will.
  • a leaf spring has that Advantage that the force application point on the hinge tab can be distributed over the entire hinge width.
  • the projections on the hinge tabs are provided one each parallel to the axis of rotation of the single-axis joint to form a running groove. In this groove can accordingly engage shaped ends of a leaf spring and so that the projections reach behind.
  • the groove is interrupted by at least one stiffening rib is.
  • the leaf spring is corresponding recessed to allow penetration of the stiffening ribs to enable.
  • the hinge tabs can be close to the axis of rotation of the Have lateral projections arranged in a single-axis joint, that hook into the hinge pots.
  • the side Protrusions serve to better support the hinge tabs in the hinge cups, so that such single-axis hinges can absorb higher forces.
  • the Leaf spring assembly consists of two leaf springs, wherein an outer leaf spring at least partially form-fitting sits on an inner leaf spring.
  • the double arrangement a leaf spring has the advantage that when used the tensile and compressive stress in each one Leaf springs are lower, resulting in a longer service life the spring is reachable.
  • the single-axis hinge shown in Fig. 1 for at least two door leaf elements 3 existing folding doors 2, there from two hinge tabs 4.6, which are connected via a single-axis joint 5 are hinged together.
  • the hinge cloth 4,6 are in hinge pots 8,10 with a screw 11 attached, the hinge tabs 4.6 in the hinge cups 8.10 are adjustable laterally, which makes the width the joint remaining between the door leaf elements 3 9 may also only be adjustable on one side.
  • the hinge cloth 4,6 have an elongated hole 15 for the passage the screw 11, the slot being orthogonal runs to the axis of rotation of the single-axis joint 5 and thus allows depth adjustment.
  • the hinge tabs 4.6 are at the bottom of the slot 15 and provided with teeth 17 on both sides of the elongated hole, with a corresponding toothing 19 of the hinge cups 8,10 is engaged and thus the hinge tab 4.6 against slipping out of the hinge cups 8.10 saves.
  • the hinge pots 8, 10 are in the door leaf elements 3 arranged sunk and with the help of a mounting plate 28 secured against twisting on the door leaf element 3 attached with screws 11.
  • the uniaxial joint 5 is from the fork part 30 of the hinge flap 4, the roller part 32 of the hinge flap 6 and the hinge pin 34 formed in the axis of rotation of the single-axis joint 5 through the fork part 30 and that Roller part 32 is passed.
  • the fork part 30 and the roller part 32 of the hinge flap 4,6 stand from the plate-shaped part of the hinge lobe 4.6 from an angle of approx. 70 to 75 °.
  • a cam-shaped Projection 14 or 16 formed on by a groove 18 or 20 is formed. They can around the ledge Engage ends of a leaf spring 12 in the groove 18 or 20 and one with respect to the axis of rotation of the single-axis joint 5 Transfer symmetrical force to both hinge tabs 4.6.
  • the projections 14, 16 are rounded and the outer contour the ends of the leaf spring 12 is the outer contour of the Adjusted projections 14,16 so that a relative movement Hinge actuation between the leaf spring 12 and the Projections 14, 16 is possible.
  • Both hinge tabs 4, 6 have in their longitudinal center plane each have a stiffening rib 22 that the groove projection combination 14,16,18,20 stabilized and on the other hand forms a position lock for the leaf spring 12.
  • the Stiffening ribs 22 are orthogonal to the axis of rotation of the single-axis joint 5.
  • the leaf spring 12, 12a, 12b is on their ends, which overlap the projections 14, 16 with a Provide recess 13 which the stiffening ribs 22nd is adjusted.
  • the projection is from the axis of rotation of the single-axis joint 5 at an angle of approx. 45 °. In the 180 ° position the projections form between the hinge tabs 4, 6 14.16 therefore an angle of approximately 90 °.
  • the leaf spring 12 presses the two projections 14, 16 in this position 180 ° towards each other, so that the hinge tab 4.6 below Preload are kept in the stretched position. You can the two hinge tabs 4.6 on one stop forming end face not shown in the drawings butt so that the hinge tabs 4.6 cannot be moved beyond 180 °.
  • hinge tabs 4.6 are laterally on both sides Projections 24 are molded into the corresponding recesses 23 of the hinge cups 8, 10 engage and thus additionally hook into the hinge cups 8,10.
  • the under hook the hinge tab 6,8 in the hinge cups increases the resilience of the single-axis hinge.
  • Fig. 8 shows the cross-sectional shape of the leaf spring 12, the is designed essentially ⁇ -shaped and with their free Ends adapted to the radius of curvature of the projections 14, 16 is.
  • leaf spring arrangement 10 shows a leaf spring arrangement with two leaf springs 12a, 12b, the one another in terms of their dimensions are coordinated that they are put on top of each other can be and together on the cam-like projections 14, 16 of the single-axis hinge can be clamped can.
  • Such a leaf spring arrangement with two leaf springs 12a, 12b has the advantage of being on the individual To reduce leaf spring acting tensile and compressive stresses which increases the service life of the leaf spring can.
  • FIG. 11 shows a further leaf spring arrangement with two Leaf springs 12a, 12b, in which the outer leaf spring 12a inner leaf spring 12b does not completely enclose.
  • a such leaf spring is cheaper to manufacture and easier to assemble.
