Abstract
A hatch for venting enclosed spaces has at least one carriage slideably mounted on a circular track so that the hatch may be opened in any direction to provide maximal ventilation. The circular track has a "T"-shaped cross-section that is slideably engaged by the carriage. The carriage carries a lockable hinge that interconnects the carriage and a hatch door. In operation, the carriage is moved around the track until the hatch door is oriented with respect to wind so that an optimal amount of air is directed by the hatch door into the enclosed space to be ventilated. The carriage can be locked into position at any preselected point on the track. The lock is spring-loaded and it is therefore easy to unlock the carriage and re-position it when the wind changes directions.
