Definitions

  • the present invention relates to a housing for Hearing aids or hearing aids according to the preamble of claim 1.
  • Hearing aids or hearing aids generally have one in operation closed housing resp. Housing shell on. Since the Devices operating a number of environmental influences are exposed, these housings, also at multi-part construction, be tightly closed. Therefore leave the housing is usually only using special Tools and by appropriately trained personnel to open.
  • lids are for example by means of a metal axis, which both through the cover as it leads through the housing.
  • the lid is from the outside in the Opening insertable, with the lid resilient in corresponding recesses in the housing snap into place Hinge elements is equipped. So that can Lid are made in one piece, but there is Danger of improper use of the cover disengages the recesses and is lost or is damaged.
  • Another known variant is that respective openings by means of a flexible Hinge and flexible material of existing cover, for example made of rubber.
  • the disadvantage This variant is that due to the flexibility and resilient property of the hinge part of the lid often snaps open again independently. falls before the intended intervention through the opening could take place.
  • the object of the present invention was a Find housing with cover, which without much effort is to be produced and the lid reliably against unintentional removal is secured.
  • the cover is made of one piece with cones pointing outwards.
  • the pegs from the inside of the Housing can be inserted into the grooves, but for Stop on the outside through the limits. So that the lid can not directly from the front Housing can be pulled out or removed, which also includes a unintentional or independent loosening of the lid is reliably prevented. Nevertheless, the onset of the Lid in the housing easily possible and can for example also from the front.
  • the lid must be provided with the pin End in the twisted position from the front into the opening of the Housing inserted and then like that be twisted until the pegs from the inside of the Engage housing in the open grooves there.
  • the lid can then be swiveled into the Housing, usually pulled against the stop of the grooves and close the opening as intended or by pivoting essentially around the pin axis be opened.
  • the lid and the Tenon from a single part and can be easily and Inexpensive, for example made of plastic, also in large Quantity can be produced economically.
  • the lid is preferably rounded in the area of the pins, and preferably has at least some areas cylindrical shape. This allows this area of the Lid against a suitably trained wall part of the Get into the housing and oppose it there support, resulting in high mechanical strength leads.
  • the pins are preferably lying on one axis Lid formed. This axis is the same the pivot axis of the cover when installed.
  • the pins preferably have a circular shape Cross section on. This also makes it easy to use the tenons insert into the grooves and into the end position of the Move the cover.
  • At least one resilient tab on the housing arranged, which at least in some areas with the lid when installed, preferably in the area of the pegs, comes into resilient stop and part of the Swiveling hinge of the lid forms.
  • this tab can be the lid in the Snap the intended end position into place Fix position.
  • a swivel hinge together with the pins guided in the grooves. This makes it a reliable pivoted lid formed, which is neither unintentionally still independently from its final position in the Can solve the housing.
  • the tab is preferably part of the housing educated.
  • the tab is advantageously made in one piece made of the same material as the housing and can thus integrated into the production form of the housing become.
  • the housing is preferably composed of at least two housing shells releasably connectable and is preferably made of plastic. With that one can cheap and easy production of the housing also in realize large quantities. Due to the multiple parts can be arranged inside the housing Simply insert elements and modules. assemble.
  • a hearing aid or hearing aid is also used a housing according to one of claims 1 to 6 proposed.
  • Figure 1 shows the view of the housing behind the ear Hearing aid to be worn, consisting of a rear Housing shell 1 and a front housing shell 2.
  • the front housing shell 2 are on the outside directed surface formed several openings, including opening 3 for outside access the electronic components arranged underneath.
  • FIG. 1 In the representation of Figure 1 are for the sake of clarity only the two housing shells 1 and 2 shown without the ones usually inside the housing electrical resp. electronic components for Sound reinforcement.
  • the opening 3 is through the in the front housing shell 2nd pivotably arranged lid 4 closable.
  • the Cover 4 is here in the half-open position shown.
  • FIG 2 is the longitudinal section through the Area of the opening 3 shown.
  • the lid 4 can of the inside of the housing shell 2 outwards the opening 3 are pushed.
  • These pins 5 can now from the inside in each at the edge the opening 3 formed in the wall of the housing shell 2
  • Grooves 6 are introduced. These grooves 6 are against that Interior of the housing shell 2 open and run as in the Figure 2 shown, advantageously in a Z shape inside the wall of the housing shell 2.
  • the cover 4 can now be shown in FIG Position can be moved along the grooves 6. There the pins 5 of the cover 4 reach the rear Stop 6 'of the grooves 6.
  • a resilient tab 7 is formed, which from below against the lid bottom 4 'comes into resilient stop. If the lid underside 4 'is advantageously rounded is a snap-in connection between the Cover 4 and the housing shell 2 are created.
  • the underside of the lid 4 'is advantageous rounded cylindrical and the tab 7 has a appropriately rounded recess and thus forms a hinge for the lid 4, as special is clear from Figure 4.
  • the lid 4 can now not be pulled outwards because the pins 5 come into abutment against the grooves 6 here and reliably prevent this. Nevertheless, according to the Simply open the housing shell 2 and the cover 4 and will be removed if necessary.
  • the cover 4 is made in one piece from a single piece, and can be produced easily and inexpensively.
