Definitions

• the invention relates to a single-axis hinge, in particular for folding doors with a plurality of door leaf elements, according to the preamble of claim 1.
• Single-axis hinges of this type are required in order, for example, in the case of folding doors, to be able to lock and open the individual door leaf elements in the manner of an accordion.
• these single-axis hinges can absorb high torques and forces and also offer the possibility of adjusting the joint width between the individual door leaves.
• a disadvantage of the known single-axis hinge is that the individual door leaves are not fixed relative to one another, so that the length of the door leaves often does not run exactly in one plane, and that depending on the angular position of the hinge, considerable forces have to be expended in order to achieve this Push the door leaf elements of the folding door further together when opening.
• the invention is therefore based on the object of developing a single-axis hinge of the type mentioned at the outset, in which symmetrical forces are exerted on adjacent door leaf elements, the door leaves being kept aligned in the extended closed position.
• a spring acts under tension on both hinge tabs in such a way that they are held in a first stable position in a closed position of the folding door at a mutual angle of 180 °.
• Such a single-axis hinge holds the door leaf elements of a folding door in their extended position, as a result of which the door leaves are held in one plane without them e.g. can move in space under the influence of pressure fluctuations.
• Such a folding door is therefore kept stable without the door leaf elements rattling.
• the spring presses both hinge tabs in the extended position of the door leaf elements, that is to say in the closed position of the folding door, against a stop which limits the angular position of the hinge tabs to one another to an opening angle of 180 °.
• a stop serves to prevent the hinge from being able to assume an open position beyond 180 °.
• the spring can also hold the hinge tabs in an open position of the folding door at a mutual angle of the hinge tabs of approximately 0 ° in a second stable position, so that the door leaf elements are also held together compactly in their open position.
• the spring exerts a restoring force on the door leaf elements and facilitates the actuation of a folding door in the direction of the end positions.
• the axis of rotation of the single-axis joint is arranged on the inside of the hinge lobe in relation to the swivel range of the hinge lobe.
• the arrangement of the axis of rotation on the inside of the hinge lobe makes it possible to pivot the hinge lobe and thus the door leaf elements by 180 °.
• the spring is also arranged on the inside of the hinge flap in relation to the swivel range of the hinge flap.
• a spring arranged in this way reaches its widest spread position at an angle of 90 ° between the hinge lugs. In this position, a dead center is reached with regard to the force acting on the hinge lobe, since the symmetrical forces of the spring cancel each other out and do not generate any torque on the hinge lobe. Before this dead center is reached from the open position, the hinge flaps are pressed apart, while after the dead center has been exceeded, the hinge flaps are pressed together due to the spring force.
• the spring consists of a leaf spring arrangement with at least one leaf spring which engages behind both hinge tabs on at least one projection each.
• a leaf spring has the advantage that the force application point on the hinge lobe can be distributed over the entire hinge width.
• the projections on the hinge lobe are provided to be formed by a groove running parallel to the axis of rotation of the single-axis joint. Appropriately shaped ends of a leaf spring can engage in this groove and thus engage behind the projections.
• the groove is interrupted by at least one stiffening rib.
• the leaf spring is recessed accordingly in order to enable the stiffening ribs to be penetrated.
• the hinge lugs can have lateral projections which are arranged in the vicinity of the axis of rotation of the single-axis joint and which hook under the hinge cups.
• the lateral projections serve to better support the hinge tabs in the hinge cups, so that single-axis hinges of this type can absorb higher forces.
• the leaf spring arrangement consists of two leaf springs, an outer leaf spring being at least partially positively seated on an inner leaf spring.
• the double arrangement of a leaf spring has the advantage that the tensile and compressive stresses in each individual leaf spring are lower during use, whereby a longer service life of the spring can be achieved.
• stretchable seals can be arranged between the end faces of the door leaf elements, which make it possible to seal the hinge area or the entire joint between two door leaf elements of the folding door.
• 1 is a plan view of a single-axis hinge connecting two door leaf elements
• FIG. 3 is a plan view of a hinge cloth with fork part
• FIG. 9 is a side view of the leaf spring of FIG. 8,
• Fig. 10 is a plan view of a leaf spring arrangement with two leaf springs.
• FIG. 11 is a plan view of a further leaf spring arrangement.
• the single-axis hinge shown in Fig. 1 for at least two door leaf elements 3 existing folding doors 2, consists of two hinge lugs 4, 6 which are articulated to one another via a single-axis joint 5.
• the hinge tabs 4, 6 are fastened in hinge pots 8, 10 with a screw 11, the hinge tabs 4, 6 in the hinge pots 8, 10 being adjustable laterally, so that the width of the joint 9 remaining between the door leaf elements 3 may also only be is adjustable on one side.
• the hinge tabs 4, 6 have an elongated hole 15 for the passage of the screw 11, the elongated hole being orthogonal to the axis of rotation of the single-axis joint 5 and thus allowing depth adjustment.
• the hinge lugs 4, 6 are provided on their underside at the level of the elongated hole 15 and on both sides of the elongated hole with a toothing 17 which engages with a corresponding toothing 19 of the hinge cups 8, 10 and thus the hinge lugs 4, 6 secures against slipping out of the hinge cups 8, 10.
• the hinge pots 8, 10 are recessed in the door leaf elements 3 and secured against rotation by means of a fastening plate 28 on the door leaf element 3 with screws 11.
• the single-axis joint 5 is formed by the fork part 30 of the hinge flap 4, the roller part 32 of the hinge flap 6 and the hinge pin 34, which is passed through the fork part 30 and the roller part 32 in the axis of rotation of the single-axis joint 5.
• the fork part 30 and the roller part 32 of the hinge flap 4, 6 protrude from the plate-shaped part of the hinge flap 4, 6 at an angle of approximately 70 to 75 °.
• a cam-shaped projection 14 or 16 is formed, which is formed by a groove 18 or 20.
• the ends of a leaf spring 12 can engage in the groove 18 or 20 and transmit a force symmetrical with respect to the axis of rotation of the single-axis joint 5 to both hinge lugs 4, 6.
• the projections 14, 16 are rounded and the outer cone ⁇ ture of the ends of the leaf spring 12, the outer contour of the projections 14, 16 is adapted so that a relative movement when the hinge is actuated between the leaf spring 12 and the projections 14, 16 is possible.
• Both hinge lugs 4, 6 each have a stiffening rib 22 in their longitudinal center plane, which stabilizes the groove / projection combination 14, 16, 18, 20 and on the other hand forms a positional securing for the leaf spring 12.
• the stiffening ribs 22 run orthogonally to the axis of rotation of the single-axis joint 5.
• the leaf spring 12, 12a, 12b is provided at its ends, which overlap the projections 14, 16, with a recess 13 which is adapted to the stiffening ribs 22.
• the projection protrudes from the axis of rotation of the single-axis joint 5 at an angle of approximately 45 °.
• the projections 14, 16 therefore form an angle of approximately 90 °.
• the leaf spring 12 presses the two projections 14, 16 towards one another in this position of 180 °, so that the hinge tabs 4, 6 are held in the extended position under pretension.
• the two hinge lugs 4, 6 can abut one another on an end face that does not form a stop in the drawings, so that the hinge lugs 4, 6 cannot be moved beyond 180 °.
• hinge tabs 6, 8 are formed laterally on both sides, which engage in corresponding recesses 23 in the hinge cups 8, 10 and thus additionally hook into the hinge cups 8, 10. The hooking of the hinge tabs 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, which is essentially ⁇ -shaped and its free ends are adapted to the radius of curvature of the projections 14, 16.
• 10 shows a leaf spring arrangement with two leaf springs 12a, 12b, the dimensions of which are matched to one another in such a way that they can be slipped over one another and can be clamped together onto the cam-like projections 14, 16 of the single-axis hinge.
• Such a leaf spring arrangement with two leaf springs 12a, 12b has the advantage of reducing the tensile and compressive stresses acting on the individual leaf spring, as a result of which the service life of the leaf spring can be increased.
• FIG. 11 shows a further leaf spring arrangement with two leaf springs 12a, 12b, in which the outer leaf spring 12a does not completely surround the inner leaf spring 12b.
• Such a leaf spring is cheaper to manufacture and easier to assemble.
