Claims
- 1. A mechanism for controlling the flow of air from an air-conditioning unit, comprising:
- a plurality of guide vanes located within an air outlet of said air-conditioning unit, said plurality of guide vanes engaging in rotational movement to adjust a direction of said flow of air;
- pivotal bearings located at edge portions on one side of each of said plurality of guide vanes;
- sleeves fitted over said pivotal bearings to hold said pivotal bearings in place; and
- shafts inserted within said sleeves and connected to an inner wall of said air-conditioning unit.
- 2. An air-direction adjusting apparatus in an air-conditioning equipment, which comprises guide vanes which are disposed in a blow-outlet and which make rotational movement to thereby change the air direction, wherein each vane has a C-shaped annular pivotal bearing and a sleeve fitted into the bearing so as to be held by the bearing, a shaft extending from an inner wall of the blow-outlet being inserted into the sleeve, the shaft having claws which project from the upper end portion of the shaft so as to retain the sleeve.
- 3. Apparatus as claimed in claim 2, in which there is a guide vane of a first type at one end of a set of the guide vanes, a guide vane of a second type at the other end, and guide vanes of a third type intermediate the two end guide vanes, there being non-sliding connections between the two end guide vanes and a link connecting all the guide vanes of the set.
- 4. Apparatus as claimed in claim 3, in which each intermediate guide vane has a slot in which a shaft on the link is received to connect the guide vane to the link.
- 5. Apparatus as claimed in claim 4, in which one shaft on the link is received in a bearing portion of one of the intermediate guide vanes.
