Patent ID: 6901774

Claim:
In an air-cooling/tempering device for a glass plate comprising a plurality of upper blowing members for blowing air to an upper face of a bend-shaped glass plate heated to a high temperature and a plurality of lower blowing members for blowing air to a lower face of the glass plate, the air-cooling/tempering device for a glass plate being characterized by comprising: a first link mechanism comprising a plurality of four-bar linkages and being formed by connecting a plurality of units each having a common link, a first connecting link connected to an end portion of the common link so as to be rotatable and a second connecting link connected to the other end of the common link so as to be rotatable, the first link mechanism being connected to the upper blowing members, and a second link mechanism comprising a plurality of four-bar linkages and being formed by connecting a plurality of units each having a common link, a first connecting link connected to an end portion of the common link so as to be rotatable and a second connecting link connected to the other end of the common link so as to be rotatable, the second link mechanism being connected to the lower blowing members so as to oppose the first link mechanism, wherein first connecting links of adjacent units in the first and second link mechanisms have respectively an end portion around which a gear cut portion is formed, and the first connecting links are connected to one end portions of the adjacent common links so as to be rotatable under the condition that gear cut portions of the first connecting links of adjacent units are meshed with each other, and the first link mechanism and the second link mechanism are respectively capable of swinging around a predetermined fulcrum point of swing.
