Definitions

  • the spring element is designed as a torsion spring which is on the one hand fixed to the column console and on the other hand with the rotationally fixed to the door bracket arranged cam plate is engaged ,
  • the free end of the torsion spring engages in certain opening angles of the door associated detents on the drive plate and thus locks the open door in preset positions, which are determined by the number and arrangement of the notches (see, eg US-A-5850673 ).
  • Such hinges have the disadvantage that wear phenomena occur with increasing life, which result in a reduction of the torque required for pivoting the door, resulting in an increasingly unreliable detent locking of the door in the respective position.
  • the torsion spring at least in the contact area with the drive plate through or at least surface hardened. The contact area is also pronounced to create a predefined contact surface on the torsion spring.
  • a hardening of the spring element has the disadvantage that it is time-consuming and expensive.
  • the surface hardening also makes the use of special and very expensive hardening process, such. B. laser hardening required.
  • the hardening also has the disadvantage that the spring characteristics of the spring element, especially in case of through hardening, be influenced in a negative way.
  • the invention has for its object to provide a door hinge and a spring element for a door hinge, which can be produced inexpensively and ensure a substantially constant operating torque over the entire life of the hinge.
  • the invention solves the problem by a door hinge according to claim 1 and by a torsion spring according to claim 7.
  • Advantageous developments of the invention are given in the dependent claims.
  • Characteristic of the door hinge according to the invention is a cam which is arranged rotationally on the running in the region of the driver plate free end of the spring element, that the cam with its lateral surface with the driver plate is engageable (claim 1).
  • the cam can, for example, through hardened, partially cured or even surface hardened, in particular, the through hardening by the ability to edit a variety of cams simultaneously, is particularly cost-effective to implement.
  • the degree of hardness of the cam can be optimally adjusted by known hardening process without the risk of structural change of the Material of the spring element consists.
  • the hinge according to the invention also has the advantage that over its entire life, the torque applied for changing the locking positions remains substantially constant, whereby a consistently reliable locking of the door is achieved in the respective position.
  • the design of the spring element is basically arbitrary. Likewise, the arrangement of the cam on the free end of the spring element in any way, for example. By a force, form and / or material connection. According to an advantageous embodiment of the invention, however, the spring element is designed as a torsion spring having a tapered portion in the region of its free end and the cam has a receiving opening adapted to the tapered portion.
  • the torsion spring is characterized by its particular reliability and insensitivity to external influences, so that the reliability can be increased by a correspondingly trained door hinge in a complementary manner.
  • a arranged at a free end of the torsion spring tapered portion according to this embodiment of the invention may in principle be arbitrarily formed and has compared to the other spring element on a smaller cross-section.
  • this development of the invention allows the cam to be reliably fixed in the sliding direction on the free end of the spring element.
  • By reducing the cross-section it is also possible to maintain existing designs of known door hinges, since it is possible to form the cam and to arrange on the free end of the spring element, that no additional space is claimed.
  • An adaptation of the components known Door hinges can thus be omitted.
  • the tapered portion connects to a shoulder at the free end of the spring element and has a deviating from a circular cross-section.
  • a paragraph according to this embodiment of the invention represents an area which extends substantially perpendicular to the lateral surface of the rest of the spring element and to which in turn connects the tapered portion vertically.
  • the paragraph represents a particularly simple form for the axial positioning of the cam at the free end of the spring element, wherein an axial displacement of the cam is effectively prevented even after a long service life.
  • tapered cross section with a deviating from a circular cross-section according to this embodiment of the invention, it allows for a corresponding configuration of the receiving opening of the cam to arrange this in a particularly simple manner rotationally on the free end of the spring element.
  • the shape of the tapered cross section is basically freely selectable and can be determined depending on the moments occurring.
  • the tapered portion is formed integrally with the torsion spring (claim 3).
  • the torsion spring by this development of the invention in the transition region between the remaining region of the spring and the tapered section to a particularly high strength, whereby damage to the torsion spring is prevented in a particularly reliable manner.
  • the rotationally fixed arrangement of the cam on the free end of the spring element can in principle be done in any way.
  • the cam can be screwed, glued or welded to the free end.
  • the paragraph has at least one inclined side surface and the cam on the side surface adapted form (claim 2).
  • the side surface extends from the peripheral surface of the non-tapered region of the spring element to the paragraph arranged perpendicular to the tapered section.
  • the cam has according to this embodiment of the invention a trained accordingly Side surface, which comes in the assembled state on the inclined side surface of the spring element to the plant, so that the cam can be arranged against rotation on the free end of the spring element. Due to the simple production of corresponding side surfaces on the spring element and the cam, this can be arranged in a particularly simple manner against rotation on the spring element.
  • the cam is adapted to the contour of the notches and has a deviating from the circular cross-section, preferably at least one protruding from the lateral surface bead (claim 4).
  • the detents can be formed, for example, by a corresponding wave-shaped contour of the peripheral surface of the driver plate or by attachable to the driver plate locking rollers.
  • the design of the cross section of the cam according to this development for example.
  • the arrangement of a bead makes it possible to dispense with an expression of the spring element or the cam to produce a defined, adapted to the detents contact surface, so that the manufacturing cost of the door hinge in a complementary manner can be reduced.
  • the cam In order to ensure a reliable function of the door hinge, it is basically sufficient to arrange the cam against rotation and only in the direction of sliding against displacement on the free end of the spring element. According to a further embodiment of the invention, however, the cam is fixed against rotation and displacement on the free end of the spring element (claim 5).
  • the additional displacement protection namely the axial fixing of the cam at the free end of the spring element increases the reliability of the door hinge in a complementary manner.
  • the axial fixation can be done in any way.
  • the axial position of the cam can also be secured by a locking ring, a nut, a split pin or the like.
  • the cam is secured against rotation by means of at least one form-fitting embossing and is fixed against displacement on the free end of the torsion spring (claim 6).
  • the embossing is characterized by its particularly simple and inexpensive and at the same time reliable way to fix the cam in the desired manner at the free end of the spring element.
  • the spring element according to the invention is characterized in that it is designed as a torsion spring having a tapered portion in the region of its free end, which adjoins a shoulder and has a deviating from a circular cross-section.
  • a spring element can be produced in a particularly simple manner, for example by machining conventional and common torsion springs.
  • the production of a tapered section can be done, for example, by common machining methods, so that the spring according to the invention can be produced particularly inexpensively.
  • the door hinge shown in Fig. 1 consists of a door bracket 3 and a pillar bracket 5, which are hingedly connected to each other via a hinge pin 4, as well as one formed from a torsion spring 6 and a driver plate 7 lock. 2
  • the driver plate 7 is rotationally connected to the column bracket 3 via the hinge pin 4 and has a wave-shaped peripheral surface with two detents 8, which are associated with specific opening angles of a door, not shown here.
  • the torsion spring 6 is fixed with its the free end 9 opposite end of the pillar bracket 5.
  • the free end of the torsion spring 6 has a tapered portion 10, on which a cam 11 is pushed.
  • the cam mimics with its end opposite the free end on a shoulder 14, which extends perpendicular to the tapered portion 10 and perpendicular to the adjoining the tapered portion 10 portion of the torsion spring 6.
  • the cam 11 has a flank 17, which abuts on the spring element 6 on a side surface 15 of the torsion spring 6 in the mounted state of the cam 11, so that the cam 11 is arranged against rotation on the tapered section 10 (FIGS. 2 to 5).
  • the cam 11 is arranged on the tapered portion 10 such that a bead 12 engages with the notches 8. For axially securing the cam 11 to the tapered portion 10, the cam 11 is stamped on the tapered portion 10.
  • the spring element 6 For axial securing of the free end 9 opposite end of the spring element 6 on the pillar bracket 5, the spring element 6 has a recess 16, by means of which this spring end can be embossed with the pillar bracket 5.
