ATTACHING STRUCTURE FOR FIRE SENSOR
Document Type and Number:
Japanese Patent JP3716351
Kind Code:
B2
Abstract:
PURPOSE: To provide the fire sensor which reduces the exposed part of a ceiling face and is a small-sized rectangular parallelepiped and is suitable for the ceiling especially with respect to plan and design by providing a reverse setting prevention means which prevents the main body to be set to a set chamber from being set in the opposite direction.
CONSTITUTION: A setting member 4 is the base to set the fire sensor to a ceiling 1, and setting metal fittings 40 are provided with a holding frame 41 like a gate having a U-shaped upper side and right and left sides, a casing frame 42 obtained by extrusion processing of the body part except the frame part of a rather thin plate material, and two hook-like spring plates 43. A bending piece 40g is different in width between the front side and the rear side, and the direction in which the main body of the fire sensor is fitted to fixing metal fittings 20 is suggested by the bending piece 40g different in width and a marker 40f. Based on the suggestion of the direction by the bending piece 40g and the marker 40f, not only setting of the main body in the correct direction is guided but also the main body is prevented from being set in the opposite direction.
