Definitions

  • the invention relates to a cap for a signal generator according to the preamble of claim 1.
  • optical Signalers are used on machines, systems, vehicles or The like used to indicate operating conditions and in particular against possible dangers by delivery of to warn about optical and / or acoustic signals.
  • optical Signalers are usually with a dome provided inside which bulbs are housed. The dome and the bulbs can be on or be multicolored to have a respective Color information corresponding signal.
  • Such optical signal transmitters are also regularly with acoustic signalers combined, i. it will be in the Dome also one or more sound sources for the production of Signal tones housed.
  • the object of the invention is this sound pressure attenuation to reduce or avoid any water.
  • These Task is based on a dome or a Signal generator of the type mentioned by the characterizing features of claim 1 solved.
  • a dome according to the invention is characterized and also provided with such a dome signal generator characterized in that the sound source based on the Mounting position of the sounder with respect to the horizontal inclined arranged receiving element is mounted.
  • the Receiving element designed to vibrate.
  • Such Receiving element for example, as in known Sound generators can be provided in the form of a membrane, is vibrated by the sound source in addition stimulated, so that a greater sound intensity is generated. Due to the inclined arrangement of such an oscillatory Receiving element this is kept largely anhydrous, so the negative effects of the water are also in this Area are reduced or completely avoided.
  • the sound source is preferably on the receiving element attached, which in particular when using a swinging receiving element such as a membrane for Transmission of the vibrations is beneficial to this.
  • the Sound source is preferably glued to the Vibration transmission if possible directly and without to cause additional inert components.
  • the Receiving element connected to the outside of the calotte.
  • the cheap installation and attachment of the receiving element on the outer edge also results from this measure the almost complete use of the dome cross section for the receiving element, which is especially in swinging Execution is beneficial.
  • the dome comprises an intermediate piece for the attachment of the receiving element with sound source.
  • One Such intermediate piece can be used as a framework for the Sound source with receiving element, so that the assembly the sound source and the receiving element or a membrane can be made separately in the intermediate piece, wherein the assembly in the dome by inserting the complete, on the intermediate piece assembled unit accomplish is.
  • the intermediate piece for the connection to Receiving element and / or the dome corresponding Fasteners on to facilitate installation.
  • the receiving element glued in particular in the form of a membrane in the intermediate piece, what if using a thin elastic membrane with low cost.
  • Fasteners e.g. for a rest and / or Bayonet catch on the other dome elements or provided segments.
  • the Intermediate piece designed so that it is on a dome or can be used between different parts of a dome, so that the intermediate piece itself represents a Kalottensegment.
  • Such an embodiment has in particular at a modular construction of a dome the advantage that optional a calotte with sounder or without one can be constructed.
  • Modular structure Signalers are already in the range of optical signal transmitters to become known, for example, color combinations for a certain dome from a modular system arbitrarily and put together quickly on request.
  • connection contacts correspond preferably also provided for the optical modules Contacts when plugging in and attaching individual Modules automatically closed without further action become.
  • the radiation characteristics the sound generated by the sound source in the desired Influenced manner is also a Sound reflector provided, the the radiation characteristics the sound generated by the sound source in the desired Influenced manner. So can with the help of such a reflector For example, the emission direction in the case of reinforced cylindrical signal transmitter in the radial direction become.
  • Such a sound reflector has for this purpose advantageously one related to the mounted position of the signal generator to Horizontal inclined reflection surface or more Reflection surfaces on.
  • an inclined Reflection surface is for example a desired lateral To achieve radiation.
  • the Sound reflector designed as a separate insert part whereby in addition to the corresponding manufacturing advantages at the same time greater flexibility in putting together a according to the invention signal generator. So depending on desired radiation characteristic no reflector element or but also provided different reflector elements become.
  • Such a sound reflector for example, as Insert in a Kalottensegment, for example in the Be formed intermediate piece. If necessary corresponding fastening devices, such as Provide locking elements or turn a bayonet lock. Even the sound reflector can do this with the rest Kalottensegmenten corresponding fasteners be provided to select between individual segments to be used.
  • the sound reflector is preferably used as a cover element formed, which is arranged above the sound source.
  • the calotte 1 is with its two uppermost segments 2, 3 and a lid 4 shown. Below the segment 2 can easily connect more segments, depending if desired to a corresponding entire dome 1 can be put together.
  • the segment 3 is used as an intermediate piece 5 for receiving a Sound generator, in the present case in the form of a piezoelectric disk 6 educated.
  • the piezoelectric disk 6 is on a membrane. 7 glued.
  • the membrane 7 can also be self-adhesive be.
  • Such a membrane is for example made of the material Pokalon can be produced.
  • the membrane 7 is circumferentially on a ring land 8 of the Intermediate piece 5, whose position in the axial direction of the Intermediate piece 5 varies so that one by the angle ⁇ inclined position of the membrane 7 results.
  • This invention provided inclination to the inclination angle ⁇ ensures that Any water in the membrane 7 or the Piezo disk 6 flows off to the side and the top specified impairments due to sound insulation prevented or reduced.
  • a reflector 9 with cone-shaped reflection surface 10 is arranged above the piezoelectric disk 6 and the membrane 7. He is at its periphery with an inner shoulder 11 on one annular, the inner shoulder 11 corresponding External shoulder 12 of the intermediate piece 5 launched.
  • the intermediate piece 5 and thus the entire dome 1 is closed by the lid 4, which has a peripheral side projecting detent spring 13 in a corresponding annular groove 14 of the intermediate piece 5 is locked.
  • the illustrated embodiment allows the Realization of the invention in a very flexible Module system for the construction of different signal transmitters.
  • Essential here is the oblique or inclined arrangement serving as a receiving element membrane 7 for the Sounder or the piezoelectric disk 6 to in this area Impairment by water or other liquids to avoid.
  • small solid particles in the form of Dust grains or the like may be present in this Arrangement especially during operation under vibration the sound source and / or the receiving element through the oblique arrangement be shaken off, so that too a Impairment of function by such foreign bodies reduced or avoided.
