Definitions

  • the invention relates to a hearing aid according to the preamble of patent claim 1; Such a hearing aid is known through the Siemens INIFINITY Pro hearing aid. Moreover, the invention relates to a battery compartment according to the preamble of patent claim 10; Such a battery compartment is known by the same device mentioned above.
  • a housing with a battery compartment for receiving a battery.
  • the battery compartment is locked with a locking mechanism in the housing.
  • This locking mechanism is often equipped with a child safety lock so that the locking mechanism can only be locked by a special tool, e.g. a small screwdriver or a sharp object, can be opened.
  • a known locking mechanism has a slider with a bore which forms a fit with the shaft, such that the slider for locking and unlocking the battery compartment is slidably disposed in the housing on the shaft.
  • a fit is to be understood as a combination of two interlocking parts with coordinated dimensions.
  • the shaft engages the bore, wherein the outer diameter of the shaft corresponds approximately to the inner diameter of the bore.
  • both the bore and the shaft have a circular cross-section. Due to the small size of the hearing aid - and thus due to the cross section of the bore and the shaft - the production of a precisely matched fit is difficult. If the cross section of the bore is too large relative to the cross section of the shaft, the locking mechanism may self-unlock during operation of the hearing aid and possibly even fall out of the battery by itself. This is a danger, especially for children, for whom the battery should not be accessible.
  • a hearing aid which has a pivotable battery compartment with a locking mechanism.
  • the locking mechanism includes a slider which blocks the pivotal movement of the battery tray in the locked position.
  • the invention is therefore an object of the invention to provide an easily unlocked locking mechanism, which provides a reliable protection against self-unlocking.
  • the problem is solved by a hearing aid according to claim 1 and by a battery compartment according to claim 10.
  • This principle of construction allows, in particular, an interference fit between the bore in the slider and the shaft, without thereby significantly hindering the unlocking of the locking mechanism.
  • a press fit is particularly insensitive to variations in manufacturing tolerances, since even if the cross section of the shaft is smaller than intended, the shaft is still in firm contact with the bore in the slide and thus an automatic release of the locking mechanism is prevented.
  • the cross-section of the shaft is rotationally symmetrical such that it is imaged on itself by an angle of 360 ° / n in rotations about the center of rotation, where n is an integer and greater than 1.
  • the slider of the locking mechanism engages in locking the battery compartment in a corresponding locking bracket in the battery compartment. Conversely, when the shaft is attached to the battery compartment, the slider of the Locking mechanism in a locking holder of the housing of the hearing aid.
  • the attachment of the shaft to the housing or to the battery compartment is particularly easy by a fit with a hole in the housing or the battery compartment. To provide a particularly secure hold, this hole has the same cross-section as the shaft itself.
  • a trilobular cross section of the shaft (n 3), since such a cross section brings the shaft at three points with the circular wall of the bore in the slide in contact and due to the simple shape in a size which is suitable for a Hearing aid, easy to make.
  • a shaft with such a cross-section is mechanically very stable.
  • a cylindrical shaft with a base corresponding to one of the aforementioned cross-sections is particularly easy to manufacture and allows easy linear displacement of the slide along the shaft.
  • the shaft is along three parallel lines in the longitudinal direction of the shaft in contact with the bore of the slider, so that the slider can be easily moved along these lines.
  • the shaft may be helical.
  • FIG. 1 shows a hearing aid 1 of the prior art with a microphone opening 2, a volume control 3, a programming socket 4, a program button 5 with an off function and a battery compartment 6 with a locking mechanism.
  • FIGS. 2 to 4 each show a perspective view of the lower end of the hearing aid 1 from FIG. 1 with the battery compartment 6.
  • the perspective view is opposite FIG. 1 something turned to that in the Figures 2-4 illustrated opening and closing of the battery compartment 6 to make it more visible.
  • FIG. 2 shows the opening of the battery compartment 6 by pivoting out of the housing 7 of the hearing aid 1.
  • the Battery compartment 6 connected to the housing 7 via a pivot axis and on the other side is the locking mechanism, with only the slider 8 of the locking mechanism is visible.
  • FIG. 3 shows the battery compartment 6 in an open state while the battery 9 is inserted into the battery compartment 6.
  • FIG. 4 shows how the battery compartment 6 is closed by pivoting into the housing 7 again.
  • FIG. 5 shows in an enlarged perspective view again the lower end of the hearing aid 1 with the battery compartment 6. It is shown how the locking mechanism by moving the slider 8 by means of a screwdriver 10 is to lock or unlock. To recognize is also suggestively the shaft 11, of which the slider 8 is guided.
  • FIG. 6 shows in a perspective view the battery compartment 6 with the locking mechanism.
  • the shaft 11 outside the bore 12 in the battery compartment, in which the shaft 11 is otherwise shown.
  • the slider 8 has a locking bolt 13, which engages in a housing of the hearing aid 1 for locking the battery compartment in a locking holder.
  • the slider In order to operate the locking mechanism with a screwdriver, the slider also has a notch 14 into which the screwdriver 10 can reach.
  • the score is also - as in FIG. 5 recognizable - accessible in the closed state of the battery compartment 6 from the outside.
  • FIGS. 7 and 8 show a cross section and a longitudinal section through the shaft 11.
  • the shaft 11 has a substantially cylindrical shape with a circular cross-section.
  • FIG. 9 shows a cross section through the battery compartment 6 according to FIG. 6 ,
  • the shaft 11 is intended in the hole 12 in the battery compartment 6.
  • the bore 11 pierces the battery compartment 6 on both sides, so that the fit between the shaft 11 and the bore 12 must provide sufficient support that the shaft when moving the hearing aid 1 or when moving the slider 8 on the shaft 11 does not slip out of the bore 12.
  • FIG. 10 shows a section of the battery compartment according to FIG. 9 along the section plane XX in FIG. 9 ,
  • the cut surface extends transversely through the shaft 11 in a region in which the shaft 11 is inserted in the bore 12 of the battery compartment 6.
  • FIG. 11 shows a section of a cross section through the battery compartment 6 along the sectional plane XI-XI in FIG. 9 ,
  • the cut surface in turn extends transversely to the shaft 11, but this time in a region in which the shaft 11 extends through the bore in the slide 8.
  • FIGS. 12 and 13 each show a section enlargement of the FIG. 10 respectively.
  • FIG. 11 The detail enlargements show the shaft 11 in the respective bore.
  • FIGS. 6 to 13 each represent true to scale drawings to a battery compartment of the prior art. Die FIGS. 6 and 9 to 11 are also true to each other to scale.
  • FIGS. 14 to 21 correspond in their basic structure of the previously described FIGS. 6 to 13 but wherein the shaft 11 according to an embodiment of the present invention has a trilobular cross-section.
  • FIGS. 15 and 16 show a transverse or longitudinal section through the shaft 11th
  • FIG. 15 In particular, the trilobular cross section of the shaft 11 can be seen.
  • the outer contour has 3 circular cutouts 15 to 17 and 3 straight pieces 18 to 20 between the circular cutouts 15 to 17.
  • FIG. 18 shows the in FIG. 17 drawn section XVIII-XVIII and FIG. 19 shows the in FIG. 17 drawn section XVIIII-XVIIII.
  • FIG. 20 In the magnification view in FIG. 20 the fit between the shaft on the one hand and the bore 12 of the battery compartment 6 on the other hand is shown.
  • the bore 12 in the battery compartment 6 has the same trilobular cross section as the shaft 11, so that on the one hand the shaft 11 is secured against rotation along the longitudinal axis of the shaft 11 in the bore 12 and on the other hand by the fully circumferential contact of the shaft 11 with the bore 12th a very tight fit of the shaft 11 in the bore 12 against slipping along the longitudinal direction of the shaft 11 is ensured.
  • FIG. 21 shows the fit between the shaft 11 on the one hand and the bore in the slider 8 on the other.
  • the cross section of the bore in the slide 8 deviates from the cross section of the shaft 11.
  • the cross section of the bore through the slide 8 is circular, so that the shaft 11 is only in contact with the wall of the bore in the slide 8 at the outermost points of the circular cutouts 15 to 17. This reduces the static friction and allows a displacement of the slider 8 on the shaft 11 without much resistance.
  • the fit between the shaft 11 and the bore in the slide 8 is an interference fit, so that a secure hold of the slider 8 is ensured against slipping without exerting a force in the direction of the longitudinal axis of the shaft 11 on the slide 8.
  • the press fit is on the one hand designed so that a certain threshold value of a force in the direction of the longitudinal axis of the shaft 11 must be exceeded before the slide 8 moves on the shaft 11. This threshold of force is such that it is not exceeded by merely moving (e.g., shaking) the hearing aid 1. On the other hand, the threshold value is such that it is easily exceeded by external action with the screwdriver 10 on the notch 14 of the slider 8.
  • the invention is not limited to a trilobular cross section of the shaft 11. Any cross section having the aforementioned discrete rotational symmetry is basically suitable for this invention. Some more examples are in the FIGS. 22 to 26 shown.
  • a trilobular form can also be designed differently than in FIG. 15 shown.
  • Another example is in FIG. 26 displayed. This in FIG. 26 The example shown is similar to a solid rounded triangle.
