  • the number of second springs 34 is not limited to the number of first springs 33 and may be different from the number of first springs 33.
  • the second springs 34 do not have to be opposed to the first springs 33 and the working plate 32 in a one-to-one manner in the longitudinal direction (moving direction).
  • the second spring 34 may be displaced in the width direction of the operation plate 32 with respect to the corresponding first spring 33.
  • the number of the second springs 34 is not limited to two, but may be three or more, or one. Even if there is only one second spring 34, for example, by selecting a material, it is possible to cope with a wide range of required spring force without much increasing or decreasing the winding diameter or wire diameter.
  • the first spring 33 may bias the operating plate 32 to the closed position
  • the second spring 34 may bias the operating plate 32 to the open position.
  • the ventilation port 31a may be opened and closed by rotating the operation plate 32 within an angle range around an axis provided in the main body 11.
  • the first spring 32 and the second spring 31 may be provided so as to face each other in the direction of the rotation with the operation plate 32 interposed therebetween, and the plurality of first springs 32 may be arranged in the direction of the shaft.
  • the ventilation port 31a may be opened and closed by the operation plate 32 sliding in the width direction.
  • first spring 32 and the second spring 31 may be provided so as to face each other in the width direction of the operation plate 32 with the operation plate 32 interposed therebetween, and the plurality of first springs 32 are arranged in the longitudinal direction of the operation plate 32. It is good to line up.
  • the second spring locking holes 31g are provided with ventilation plates.
  • a plurality of the terminals 31 (and thus the apparatus main body 11) may be arranged in a grid pattern on the second end side portion.
  • the locking holes 32g are not provided when the operating plate 32 is manufactured.
  • the locking hole 32g may be formed at a position that matches the required spring force of the second spring 34.
  • the locking holes 31g are not provided, and when the individual second springs 34 are attached, the positions corresponding to the required spring force of the second springs 34 are related.
  • a stop hole 31g may be formed.
  • the spring engaging portions 32f and 32g are not limited to holes, and may be hooks or convex portions provided on the operation plate 32.
  • the spring engaging portions 31f and 31g are not limited to holes, but may be hooks or convex portions provided on the ventilation plate 31.
  • the springs 33 and 34 are not limited to tension coil springs, and may be compression coil springs or leaf springs.
  • the biasing means 38 and 39 may include an elastic member other than a spring, such as rubber.
  • the present invention can be applied to a ventilation device attached to a wall, a sash, a horizontal rail, a vertical, a door, or the like of a building.

Abstract

Une plaque d'actionnement (31) permettant l'ouverture et la fermeture automatiques d'un dispositif de ventilation (10) est poussée soit en position ouverte soit en position fermée par un premier moyen de pression (38). De plus, la plaque d'actionnement (31) est poussée par un deuxième moyen de pression (39) du côté opposé au côté vers lequel le premier moyen de pression (38) pousse la plaque d'actionnement (31). Des premiers ressorts (33) en alliage à mémoire de forme sont utilisés comme premier moyen de pression (38). Les premiers ressorts (33) sont placés dans la direction perpendiculaire à leur direction de pression. Grâce à cette configuration, sans modification importante des dimensions des ressorts en alliage à mémoire de forme, telles que le diamètre de spire et le diamètre de fil, le dispositif de ventilation peut respecter de façon fiable les spécifications, y compris la performance de ventilation.
