Definitions

  • the present invention relates to an alarm device for generating an alarm when a child, person or animal falls into water.
  • the present invention provides a device for giving an alarm when it enters water, comprising:
  • a frame for fastening to a person - a housing for holding a sound source
  • an attaching member for attaching the housing releasably to the frame
  • an actuator for actuating the releasable attachment of the attaching member, which actuator can be activated by means of contact with water.
  • An advantage of a device according to the inven- tion is that a loud noise can be generated, while hearing impairment can also be prevented since a certain distance can be provided between the housing and the person who falls into the water.
  • a further advantage is that the device is released from the casualty, whereby it can float to the surface and here generate sound through the air unhindered by the water.
  • the sound source is disposed in the alarm position such that water can flow off the sound source.
  • the alarm sound is not damped by water which has for instance entered the housing when the housing is submerged in water when the casualty falls into the water. Because the water can flow off, the sound source can dry rapidly and once again be able to generate the alarm sound.
  • the device has a centre of gravity such that during floating in a body of water it will move into a substantially vertical orientation.
  • This vertical orientation is suitable in this em- bodiment for holding the upper part of the housing, and the sound source in the housing, directed upward. This vertical orientation therefore contributes toward the alarm signal being generated optimally.
  • a part of the housing preferably forms a float body.
  • the sound source preferably comprises a membrane which can more preferably be actuated by means of a p ⁇ ezo element.
  • a membrane is highly suitable for placing in the desired orientation. With a correct fitting such a membrane can also form a covering for the float body.
  • a further advantage of a piezo-membrane according to the present invention is that a penetrating tone can be generated while the membrane can also take a moisture-resistant form.
  • the membrane is preferably arranged in the housing such that a slope is created for draining water under the influence of the force of gravity. Such a slope results for instance from an inclining orientation of the membrane relative to the vertical when the housing is floating on the water.
  • a slope results for instance from an inclining orientation of the membrane relative to the vertical when the housing is floating on the water.
  • the water will be discharged quickly, thereby ensuring correct functioning of the device for generating an alarm.
  • the attaching members comprise a first biasing member for holding under bias a release element which holds the housing in an attached position relative to the frame by means of the actuator, and wherein actuation of the actuator causes a movement of the releasable attachment under the bias for the purpose of releasing the attachment.
  • a second biasing member is preferably provided for the purpose of providing an ejection impulse to the housing relative to the frame.
  • a relatively strong or relatively weak spring can be applied for this purpose.
  • the actuator is a soluble tablet, such as preferably a tablet comprising a salt. Depending on the salt chosen, such a tablet can be dissolved or disintegrate in water quickly or relatively slowly, whereby the housing is released relative to the frame.
  • the actuator preferably comprises a so-called secumar pill.
  • the device comprises a connecting member for providing a connection at a distance between the person or the frame and the housing. It hereby becomes possible to ensure that the housing continues to float at a distance from the casualty such that the alarm signal also points to the casualty. Particularly in cases where the casualty him/herself is not able to give any sign of life, it is important that the casualty can be found.
  • An advantage of the present invention is therefore on the one hand that a loud signal can be generated without this excessively disturbing the casualty auditively or causing pain, while it is also possible that the distance between the casualty and the alarm signal, or at least the source thereof, does not become too great.
  • the device comprises switch-on means actuable by means of water for the purpose of switching on the alarm signal. It is possible here to envisage two electrically conductive contact points which protrude from the housing at some mutual distance, wherein an actuation signal can be generated in per se known manner by submersion thereof.
  • the device preferably comprises a programmable processing unit for generating a signal for reproduction thereof by the sound source.
  • a programmable processing unit for generating a signal for reproduction thereof by the sound source.
  • the housing of the device comprises an upper body and a body extending eccentrically thereunder as seen in bottom view.
  • the design of the housing and the frame is more preferably such that there is a space between them, whereby release is enhanced. In the case of contamination such a space can be easily flushed clean when entering water.
  • a spherical shape of the top side of the housing- provides the further advantage that during release it can function as a joint for the purpose of releasing the housing from the frame.
  • the device preferably comprises a cord for connection between the housing and the frame after these have separated.
  • This cord ensures that the alarm goes off in the vicinity of the casualty, and that the alarm can be recovered. Since the cord is connected by means of the frame to the casualty, it is also functional in finding the casualty, for instance in a situation with poor visibility. If the cord is grasped, this gives at least an indication in the direction of the casualty.
  • the cord can also be applied by pulling thereon in order to pull a casualty toward the rescuer or to carry the rescuer to the casualty.
  • the device preferably comprises a reel around which the cord can be wound for storage thereof.
  • This reel is more preferably attached at or close to the middle of the cord so that, after two-sided simultaneous winding-up thereof, it can then be easily unwound again so that the distance between the frame in the housing can be optimized.
  • FIG. 2 is a perspective view of an assembled device according to the present invention.
  • FIG. 3 is a perspective view of a further as-impld embodiment.
  • Figure 1 shows a preferred embodiment of the device showing various aspects in graphic manner.
  • Device 1 comprises frame 2 and housing 3.
  • the housing is provided with arms 6,7 with protrusions on the end thereof.
  • the protrusions hook behind arms 10 of the release member 9 displaceable in the direction of arrow A.
  • the housing driven by spring 4 moves in the direction of arrow B.
  • Salt tablet 11 or other water-soluble or reactive material protrudes through a round opening 15 and the opening 16 corresponding with the blocking position of the release member. In this position of the salt tablet the release member 9 is fixed relative to the frame and cannot therefore displace in order to release the protrusions from the arms .
  • Membrane 15 is situated in a space of housing 3 in a sloping position.
  • This space of the housing comprises openings for passage of the water.
  • the water inevitably flowing inside through these openings can hereby also flow outside again, and this is stimulated under the influence of the vibrations of the membrane which are used to gener- ate sound.
  • the water also flows off the membrane under the influence of the force of gravity, since the housing will float in substantially vertical orientation.
  • the housing further comprises a battery (not shown) and two contacts 8 which are connected to a circuit controlling generation of sound by the membrane.
  • the contacts can be activated by contact with water.
  • Frame 2 ' can be fastened to clothing, belts, body parts etc., and in order to illustrate this further reference is made to figures 2 and 3.
  • the embodiment of Fig. 2, which is the same as that of Fig. 1, has a relatively large rear surface on the frame for attachment to an article of clothing or fixing in (part of) an article of clothing.
  • the embodiment of Fig. 3 has on both sides an eye 18 so that a band or belt can be passed therethrough for fastening to a body.
  • Holes 19 in the frame are suitable for admitting water when a carrier of the alarm device falls into water.
  • the salt tablet can hereby be wetted relatively quickly, and the housing therefore released and/or the alarm actu- ated.
  • the alarm is actuated by releasing the housing from the frame by means of for instance a switch.
  • a further preferred embodiment (Fig. 3-4) relates to a rescue alarm 21 comprising a frame 2 and a housing 3 mutually connected by means of a cord 23.
  • This cord can be wound up over a diabolo-like reel which can be placed freely in the lower part 37 of the frame. The cord is wound up on two sides.
  • the cord is fixed in the middle thereof to the reel.
  • a hole is preferably made for this purpose through the shaft of the diabolo through which the cord can be guided.
  • the cord can then be fixed about halfway along its length to the reel between the housing and the frame while it is being guided through the hole.
  • the reel is more preferably provided with a flange-like wall in the middle of the shaft so that the cord can be wound up on either side in opposing directions. Winding-up of the cord is preferably performed such that it is wound up simultaneously along two sides while the reel is being rotated. ⁇ -
  • the housing is constructed from the top downward as follows.
  • the upper part is formed by a substantially cupola-like top part 26 with at least an outlet opening 25, which also serves as a sound passage opening.
  • a membrane 27 for producing the sound, such as a piezo.
  • a PCB for controlling the piezo.
  • Under the PCB is situated a PCB support for supporting the PCB relative to the underside 33 of the housing and for providing an electrical contact with the upper pole of battery 30 arranged thereunder.
  • Frame 2 of this embodiment has a design adapted to this housing 3.
  • the frame further comprises eyes for guiding a belt there- through (not shown) .
  • the frame also comprises a movable pusher member 38 for ejecting the housing from the frame by means of push spring 39 after the secumar pill (not shown) has dissolved, which is also present through eye 34 for holding the housing by means of the eye.
