Definitions

  • the invention relates to a hinge.
  • the invention further relates to a one-piece hinge, in particular for use in headphone brackets, in spectacles, for the lid of small containers, for furniture doors, etc.
  • Hinges usually consist essentially of a cylindrical axis and lugs rotatably mounted thereon, to which the mutually movable parts are attached. Special forms of hinges have two mutually parallel axes through which a raising movement of a door is achieved in order to make the collision of the two mutually moving parts occur only at a large tilt angle, but are not the subject of the invention.
  • Hinges of the abovementioned type allow the parts connected to one another to be twisted until they hit one another, which means that the parts themselves must be provided with stops so as not to be damaged even under normal use.
  • the invention aims to provide a hinge which, in one direction, has a stop of its own, over which it can not be pivoted without appreciable force, possibly only when damaged.
  • a hinge characterized in that it consists of at least two elastically bendable connecting elements, for example in the form of rods, bands, wires, springs or the like, whose longitudinal extension is substantially perpendicular to the joint axis of the hinge and in that the connecting elements are offset from one another in the direction which is substantially normal to the longitudinal extent and substantially normal to the joint axis.
  • connecting elements is to be understood that they directly or indirectly connect the two parts of an object to be pivoted against each other.
  • the respective connecting element in the region of the joint axis or pseudo-axis is formed continuously, thus extending over this area.
  • each connecting element in itself already constitutes a connection between the two parts of an object to be pivoted.
  • the effect according to the invention is achieved only with two connecting elements.
  • the hinge consists of at least one band whose longitudinal axis intersects the joint axis at least approximately at right angles or crosses at a small distance, and that the band has a cross section in the normal section to its longitudinal axis, the unilaterally curved flat.
  • This corresponds to a so-called parabolic surface, consisting of straight, mutually parallel generatrix, the cross section of the tape itself can have a variety of forms, but its center line may not have a turning point.
  • Such a band can be easily curved from its rectilinear extent in the unloaded state in the direction in which its surface from parabolic to elliptical, thus double positive, is curved.
  • the band according to the invention has a great resistance to being bent from the straight, unloaded, extension into a hyperbolic curvature, since in this case the cross section must be "leveled” in the bending region, which requires a great deal of deformation work and thus acts as a stop ,
  • the band in the unloaded state in rest position on a curved longitudinal extent which can be easily achieved in the production, so that the stop corresponds to this curved rest position.

  • the cross-section of the band and / or its shape may vary over the length of the band.
  • spring steel, metallic materials in general, but also plastics and combinations thereof, for example in the form of casings or sandwich construction may be used as the material, locally or over the entire length / width of the strip. Knowing the invention and the particular field of application, the material expert can easily select the appropriate materials.

  • mounting options for the shells in particular gimbals, but the type of attachment of the shells for the present invention is of little relevance.
  • hangers where the wires for the speakers in the shells are guided along the bracket. Again, this does not affect the invention in its essence, it only concerns the formation of the temple itself.
  • the object and purpose of the invention when used as a headband is to increase the mechanical stability of these straps, to reduce the weight and to be able to slightly reduce the size of the headphone in the unused state, without compromising the wearing comfort or increasing the manufacturing cost.
  • the headband has at least a portion of a hinge according to the invention.
  • At least one hinge according to the invention in the earpiece of a headphone permits a reduction in the radius of the bow which can be carried out easily, which makes the picking up possible. and transport in the unused state much easier.
  • the hinge acts against bending like a rigid body, so that the pressing forces exerted by the other portions of the headband are transmitted to the head of the listener.
