Definitions
- the invention relates to a manually operated signal generator.
- Conventional signal lights are either provided with a battery or with an accumulator, which serve to supply the optical signal transmitter.
- signal transmitters and flashlights When such signal transmitters and flashlights are used, previous use or prolonged storage may mean that they are insufficiently charged or not charged at all at the critical point in time, as a result of which they cannot be used.
- Flashlights are also in use, which are provided with a generator circuit and a manually operated push button for the drive. They are used in the dark and have a lighting effect only in one direction, which is disadvantageous for use as a warning signal generator.
- acoustic signal transmitters which are equipped with a crank drive are. As a result, they are only suitable to a limited extent for use in different locations.
- a hand-operated signal generator with an optical and / or acoustic signal transmitter is known from WO-A-94/02776.
- the signal generator comprises an AC voltage generator with a rotatable part and a manual drive for the AC voltage generator, the signal generator being fed by the AC voltage generator and being connected to it.
- the rotatable part of the alternating voltage generator is connected to the rotating part of the signal transmitter.
- the invention has for its object to provide a hand-operated signal generator that is easy to use and is always ready for use even after long periods of non-use.
- a hand-operated signal generator thus comprises a handle part and a part which can be rotated with respect to the handle part.
- An AC voltage generator is provided in the rotatable part and is driven by the rotary movement of the rotatable part. Furthermore, an optical and / or acoustic signal generator fed by the AC voltage generator is provided.
- the lack of a battery and an accumulator has the advantage that less waste has to be eliminated, which makes the signal generator according to the invention very environmentally friendly.
- the operation of the signal generator according to the invention is extremely simple and energy-saving. It is only necessary to move and turn the handle part in such a way that the rotatable part also rotates. By turning the handle part, the rotatable part is taken along and in turn set in rotation in such a way that it needs to be kept rotating, for example, like a centrifuge or a gyroscope, with little effort.
- the handle part should be cylindrical and the rotatable part should protrude from the handle part like a flag. If the handle part is turned by hand, the flag-like rotating part starts rotating, like a ratchet. This makes the handle part very handy and the rotation of the rotatable part is very easy to initiate and maintain.
- slip clutch between the handle part and the rotatable part is very favorable for the use of the signal generator according to the invention. This leads to the fact that the rotatable part starts up relatively slowly, but is then carried along faster and faster and finally runs on. The direction of rotation is completely irrelevant.
- An advantageous embodiment of the slip clutch consists in that it comprises two cylinder parts which are movable with respect to one another, an adhesive / lubricant being introduced into the bearing gap. This adhesive / lubricant can be viscous fat, for example. In particular, it causes the relatively slow start-up or start of the rotary movement of the rotatable part until the generator also runs. Another effect of this slip or take-away clutch is that it causes a blocking effect in the event of a hang-up, whereby a safety effect is achieved. , -._ . PCT /
- the AC voltage generator according to the invention is always functional. This also applies to the manual drive, so that the signal generator scets according to the invention is ready for use. Since no high drive energies are to be applied for the AC voltage generator, the manual drive can be designed relatively easily. This ensures that the signal generator is easy to handle.
- the signal generator according to the invention can be an optical and / or acoustic signal generator. It can advantageously be provided that the optical and acoustic signal transmitters are actuated together.
- a beep or siren can be provided as the signal tone for the acoustic signal transmitter. He can also e.g. a Piezomodui with Meiodiegeber etc., which is connected to the alternator by appropriate means and, if necessary, via a rectifier.
- the acoustic signal generator can also be a tone generator with howling tones, the frequency of which may be made dependent on the speed.
- a mechanical siren can also be provided, for example a perforated siren, which is provided on the outside of the rotatable part of the signal generator.
- a perforated siren which is provided on the outside of the rotatable part of the signal generator.
- air chambers are periodically provided on the outside of the rotatable part of the AC voltage generator and air slots are located opposite them in the housing, which fill with air during rotation and because of their shape. The air can escape again through the air slots, as a result of which a periodic air movement occurs as a result of the rotary movement and a howling tone is generated depending on the number, distribution and shape of the chambers or slots and on the speed.
- the speed changes and accordingly the howling tone becomes constantly higher and lower. at active, fast rotation of the handle part, the howling tone can become very high.
- Diodes are preferably used as the optical signal transmitter, but the invention is in no way restricted to these lamps.
- the manual drive of the signal generator according to the invention can preferably comprise a flywheel which is provided in the rotatable part and with which the AC voltage generator is firmly engaged.
- the flywheel is appropriately balanced for smooth running, so that a good caster function is achieved. Because of the short-time delay caused in this way, the handle part does not have to be rotated non-stop and the user tires less quickly.
- a movable cylinder part with an end gear ring is expediently arranged in the handle part, with which a gear drive of the rotatable handle part is in engagement.
- This drive is extremely simple and user-friendly.
- the ring gear with the cylinder part can also be replaced by corresponding elements with the same effect.
- the alternating voltage generator preferably has a fixed winding with a rotating magnet, it being possible for such a permanent magnet to be glued, for example, into the flywheel.
- a permanent coil is assigned to the permanent magnet, with which the signal transmitter (s) is (are) electrically connected via ferromagnetic sheets. When the permanent magnet rotates, a low voltage is induced in the electrical coil, which generates the current for the optical or ac _. ._____ PC O 96/08069
- an electrical circuit with a transmitter is connected to the AC voltage generator.
- This generates, for example, a fixed SOS signal on an international frequency, for example in the range of 50 kHz and with an output of 1/2 watt.
- Such transmitters are suitable, for example, for being carried on boats. Their great advantage is that they are always ready for operation, while in the case of battery or battery-powered devices it can happen that they are not ready for use in the event of an emergency.
- the signal generator according to the invention is preferably constructed in such a way that the handle part consists of a base part and a cover 1, which are connected by a rod. This is very cheap in terms of production.
- a movable cylinder part with a gear rim on the end face with which, as mentioned, a gear mechanism of the rotatable handle part engages.
- the rotatable part is expediently connected to the handle part in the region between the base part and the cover part.
- the structure of the signal generator according to the invention is thus very simple and few parts are required, as a result of which the device costs are reduced. Plastic parts are expediently used.
- FIG. 1 is a partial sectional view of a signal generator according to the invention with an optical signal transmitter, the section through the handle being a longitudinal section, and
- FIG. 2 shows a sectional view in a plane perpendicular to the sectional plane of FIG. 1.
- the signal generator comprises a handle part 2 and a part 4 which can be rotated with respect to this.
- the handle part 2 consists of a cylindrical base part 6 and a likewise cylindrical cover part 8.
- the base part 6 and the cover part 8 each carry a guide - or mounting sleeve 10 or 12.
- one end of a rod 14 is seated be provided by screwing.
- the lower edge of the cover part 8 and the upper edge of the cylindrical base part 6 are arranged at a distance from one another.
- the handle-side end of the rotatable part 4 Between them is the handle-side end of the rotatable part 4. At the upper end, this has a cylindrical collar 16 which extends radially inwards with respect to a cylindrical part 18 and forms a support shoulder 20 with it. The lower edge of the cover part 8 rests on the shoulder 20.
- the base part 6 is also provided at its upper end with a shoulder 22 forming a shoulder and a ring part 24.
- the lower edge of the cylindrical part 18 again rests on the shoulder 22 in this way, the lateral surfaces of the cover part 8, the cylindrical part 18 and the handle part 6 are aligned.
- the rotatable part 4 is designed in the form of a flag and, in the exemplary embodiment shown, has an approximately quadrangular shape in the flag region 26, the front end, the end face 28, being of arched design. Near the handle-side end, the flag part 26 has a vertical wall 30 running parallel to the rod 14.
- a gearwheel gear 32, a flywheel 34, an alternating voltage generator 36, a circuit arrangement 38 and light emitting diodes 40 as optical signal transmitters 40 are arranged on the end face 28 in the flag part 26, these parts being discussed in further detail.
- a cylinder 42 which consists of a disk 44 and an inner cylinder 46 each with a central bore, is fixedly attached in the handle part 6.
- Another cylinder 48 is seated on cylinder 42 or inner cylinder 46, which has a central recess 50 at the bottom and is provided with a ring gear 52 on its upper side.
- the annular space between the inner cylinder 46 and the outer surface of the recess 50 is so narrow that the two cylinders 42, 48 act as a slip clutch.
- an adhesive is introduced into the intermediate space 52, as can be seen from FIG. 1. The effect of the adhesive is that when the cylinder 48 begins to rotate on the inner cylinder 46, it initially only starts slowly, but is then carried along more and more quickly.
- a gear 54 runs on the ring gear 52 of the cylinder 48 and is supported on a shaft 56 extending through the wall 30.
- a further gear 58 which in turn is in engagement with a ring gear 60.
- the ring gear 60 sits on the side surface of a tooth 62 provided on the end face Gear 64.
- the gear 64 is in engagement with a pinion 66 which is mounted coaxially with a further gear 68.
- the teeth 70 of the gear 68 are in engagement with a further pinion 72, which in turn is mounted coaxially with a gear 74.
- this gearwheel combination of the gearwheel gear 32 causes a translation of about 1:15.
- the teeth 76 of the gear 74 are in engagement with the teeth 82 of a gear 80 which has approximately the same diameter.
- the gearwheel 80 is connected to the flywheel 34, which in the exemplary embodiment shown e.g. made of cast metal; is.
- a permanent magnet 84 is glued into the flywheel 34, the number of poles corresponding to the number of sheet metal tabs 86, which are designed as ferromagnetic sheets.
- the rotating magnetic field of the permanent magnet 84 is guided into the interior of the coil 88 via the basket-shaped, ferromagnetic sheets 86.
- An alternating field is generated in the coil by the rotating field of the permanent magnet 84 and an alternating voltage is thereby induced.
- the AC voltage generator 36 further comprises a coil winding 88 which, like the magnetic sheets 86, is attached to the housing of the flag part 4.
- the circuit arrangement 38 mentioned is connected to the AC voltage generator 36 via lines 90. It comprises a circuit board 92, a smoothing capacitor 94, diodes 96 and the light-emitting diodes 40, which in the exemplary embodiment shown are designed in multi-color, for example in a flashing circuit. Furthermore, reflectors and optionally an electronic voltage stabilizer can be provided.
- an electronic transmitter can also be included in the circuit arrangement, which is used, for example, for use on watercraft to send SOS signals in the previous written frequencies with the required range and power.
- the parts from the flywheel 34 to the end face 28 form the mass required for the rotary movement, since these are essentially metal parts, so that together they form the flywheel mass required for the drive.
- the diodes 40 illuminate due to the induced voltage. Due to the rotation of the flag part 4 around the handle part 6, all-round lighting is achieved which provides a particularly good optical signal effect.
- the circuit arrangement can additionally contain a rectifier for the electrical supply from the AC voltage generator.
- an acoustic signal transmitter is not shown.
- This can e.g. be designed in the form of recessed air chambers, at the level of which there are louvers in the housing.
- the air chambers then fill with air in the direction of rotation. This then escapes cyclically through the louvers, creating a howling sound.
- the housing of the signal generator described is preferably made of plastic. Of course, it can also consist of metal, etc.
