Definitions

  • the invention relates to a partial bracket for a Sp Dahlkopfbügel for headphones or headsets, a connecting element for a Sp Dahlkopfbügel and headphones or headsets with such Sp Dahlkopfbügeln.
  • Spreading headband which in the GB 1,177,925 and in US 4,634,816 are used to ensure a comfortable and secure fit on the head with headphones or headsets, especially in the professional field of application.
  • the Bügelandruck so the pressure with which the headband presses the headphone clasps to the head, should not be too high.
  • the spreading of the headband is that at least two part of the bracket are spread apart and thus rest on different positions of the head.
  • the object of the invention is to provide a Sp Dahlkopfbügel for headphones or headsets, which spreads automatically when opening or widening, in use, the spread maintains and in which after use, the part bracket are brought together automatically.
  • a partial bracket for a Sp Dr Drunk for a headphone or a headset with at least two partial straps for receiving at least one headphone shell at an end portion with a substantially arcuate curvature wherein the part of the bracket has an elastic spring portion for resilient expansion and narrowing of the partial bracket in which the end regions are rotated relative to the spring region about the longitudinal axis, and are angled relative to the curvature for generating a mechanical stress in the part clip and the end regions can be mounted on connecting elements.
  • a corresponding solution of the problem is obtained with a connecting element for a Sp Dreutickopfbügel for a headphone or a headset with at least two partial straps with a substantially arcuate curvature, each partial bar has a resilient spring portion for resilient expansion and contraction of the partial bracket and two end portions, and two Connecting elements, wherein the connecting element has holding elements to which the end portions of the part yokes are mountable, wherein the holding elements for rotating the end portions relative to the spring portions about the longitudinal axis, for bending the end portions relative to the buckle and for generating a mechanical stress in the part bracket in the assembled state are configured, wherein the end portions are rotated in the mounted state relative to the spring portion.
  • the invention is based on the finding that by the introduction of mechanical stresses in the Sp Draillebügel in addition to the tension, which is caused by the opening or placement of the headphone, an automatic spreading and Wiederzusammenil the partial bracket can be effected.
  • the corresponding stresses can be generated by a torsion in conjunction with a bend.
  • the partial brackets can themselves be designed in accordance with claim 1, wherein even an assembly with conventional connecting elements enables the solution according to the invention.
  • conventional partial hangers i. those without twisting and bending, are provided in the assembly with fasteners according to claim 9 in such a way with mechanical stresses that results in a solution to the problem.
  • the elastic spring area consists continuously of a material, in particular of spring steel.
  • spring steel In view of the occurring mechanical stresses in the part of the bracket can occur in a multi-part design at the joints weak points that could break in the course of use. The use of spring steel is recommended, since a favorable production with a good handling and a good quality resistance can be combined.
  • the end portions opposite to the spring portion are rotated in opposite directions to each other.
  • the torsional stresses introduced at the end regions by this rotation during assembly complement each other.
  • the end regions are angled inwardly relative to the curvature in order to introduce a corresponding voltage during assembly.
  • the end regions are bent relative to the curvature by an angle in the range of 0 ° to 20 °, preferably in the range of 0 ° to 10 °, in particular by approximately 5 °.
  • the partial bracket is configured such that a cable is guided from one end region to the other end region through the partial bracket.
  • a cable bushing through a part of the bracket has the advantage that a signal must be supplied to the electro-acoustic transducer of the headphone on only one side of the headphone. A user is not hampered by cables running off the headset on either side of the headset.
  • the partial bracket has a sheath for guiding a cable from one end region to the other end region through the Sheathing up. In this way, a corresponding cable management is possible without changing the spring area of the part bracket itself.
  • a headphone or headset with a Sp Dahlkopfbügel and at least one earphone shell part handle and / or connecting elements according to one of claims 1 to 9, wherein at least one support for the at least one headset is arranged at the end portions of the part bracket and / or connecting elements.
  • Fig. 1 shows a front view of a partial hoop 1 according to the invention, which is evenly arched curved in the embodiment shown, so that it has the essential shape of a circular cut over an angular range of slightly more than 180 °.
  • the cross section of the partial hoop 1 substantially corresponds to a flat rectangle, the broad sides of the cross section corresponding to the inside and outside of the curvature.
  • the detail views 1a and 1b illustrate the rotation of the end regions 2a and 2b along their longitudinal axis by an angle ⁇ relative to the spring region 3, which extends in this embodiment over the entire part of the bracket 1 except the Ent Schle 2a, 2b.
  • the angle ⁇ is about 15 °.
  • Fig. 2 shows one opposite Fig. 1 Enlarged front view of an end portion 2a of a part of the invention bracket 1.
  • an angle ⁇ here inwardly, angled.
  • the angle ⁇ is about 5 °.
  • Fig. 3 shows a side view of the in Fig. 1
  • the end portions 2a, 2b each have a hole 4, which serves to facilitate a simple connection between part bracket 1 and connecting element (not shown here) by, for example, a screw.
  • the bevel 5 on the spring region 3 opposite end of the end portion 2a, 2b in combination with a corresponding configuration of the connecting element, to limit the spread of the Sp Schwarzkopfbügels to a maximum value.
  • Fig. 4 shows a front view of a headphone 6 according to the invention.
  • the headphone 6 has two partial yokes 1, whose end regions 2a, 2b (not shown) are mounted on or in connecting elements 7a, 7b, which in turn have holders 8a, 8b for receiving supporting elements 9a, 9b for headphones (not shown).
  • the part of hoop 1 are spread when using the headphone 6. This spreading is done so that the part of the bracket 1 are tilted forward or backward from the plane of the drawing.
  • the headphone 6 can also be designed so that it has only a headphone shell. However, an additional device may be provided on the end regions 2a, 2b or the connecting element 7a, 7b, on which or no headset is attached, which is pressed against the head in accordance with a headphone clam.
  • headphone and headset are to be understood as meaning not only devices having electro-acoustic transducers, but also, in a broader sense, devices serving, for example, for soundproofing or soundproofing of the ear.
  • Fig. 5 shows a cross section through a part of the invention bow 1 of Fig. 4
  • the sub-bracket 1 has a sheath 10 which extends around the spring portion 3 and has a passage 11 through which a cable from one end portion 2a, 2b of the part bracket 1 can be guided to another.
  • a Sp Dr Dr Drettigel with part of the invention and / or fasteners is user-friendly, since it automatically spreads when widening associated with the touch and after use, ie in the narrowed state, the spread automatically reverses. The user is not in danger of pinching hair, as the spread is maintained during use.
