Definitions

  • the present invention is related to a portable smoke alarm according to the preamble of the claims.
  • Portable smoke alarms especially indented for use when travelling, are commercially available in an number of different designs.
  • the alarm as such is part of a number of subjects to be packed before leaving, often in a hurry.
  • the portable smoke alarm according to the present invention comprises one main unit and one sensor unit.
  • the two units are arranged separately during use, however connected to each other to one unit when not in use.
  • the main unit comprises a battery powered alarm clock and suitably also is designed to be used as a flash light. It furthermore comprises a receiver for wireless transmission of signals from the sensor unit.
  • the main unit further comprises an alarm unit connected with the receiver which, when receiving signals from the receiver unit, activates an alarm which may be the buzzer of the alarm clock.
  • the flash light which is build into the main unit, the alarm clock and the receiver unit are all connected with the battery in the main unit which the user will ensure to be intact to be able to use the alarm clock.
  • the sensor unit comprises a smoke sensor, a battery and a transmitter, preferably for transmitting infrared beams to the main unit when detecting smoke.
  • a smoke sensor preferably for transmitting infrared beams to the main unit when detecting smoke.
  • an optical sensor is used.
  • the sensor unit may further comprise a buzzer to be activated shortly when the sensor unit is removed from the main unit in case the battery is still intact.
  • the sensor unit is provided with a clamp, a hook, lock or such, thereby making it easy to secure the unit as close to the sealing as possible, such as on curtains or other places.
  • the sensor unit is to be secured to the main unit after use, by snapping, clamping, by means of a magnet or such.
  • the buzzer is activated a short moment to indicate that the battery in the sensor unit is intact. In this way it is ensured that the user, before use of the alarm, has controlled that the battery is intact and he may possibly replace the battery with a new battery if the buzzer is not activated.
  • the main unit is such designed that the buzzer is activated in case the main unit is lifted from a table or such without having the sensor unit secured to it. This may be achieved for example by arranging in the main unit a sensor or micro switch registration that the main unit is resting on a surface and a further sensor or micro switch registration whether or not the sensor unit is secured to the main unit. When lifting the main unit without the sensor unit from a table or such, the buzzer in the main unit is activated until the sensor unit is secured to the main unit or the main unit is placed on a surface.

Abstract

Dispositif détecteur de fumée portatif avec alarme, comportant un détecteur de fumée et une sonnerie d'alarme à piles. Le dispositif comporte une unité centrale à laquelle peut être fixée détachablement une unité détectrice comportant un détecteur de fumée, et un émetteur de signal assurant la radio-émission de signaux en direction de l'unité centrale lors d'une détection de fumée, et conçue pour pouvoir se fixer détachablement à proximité du plafond d'une pièce, par exemple à un rideau. L'unité centrale comporte une sonnerie d'alarme, par exemple un vibreur, un récepteur destiné à capter les signaux provenant de l'unité détectrice, et une pile alimentant le vibreur. L'unité centrale comporte également un détecteur ou un interrupteur apte à déterminer si l'unité détectrice est fixée ou non à l'unité centrale, ledit vibreur étant actionné si l'on ramasse ladite unité centrale avant d'avoir fixé à celle-ci l'unité détectrice.
