DEFINITION

Classification: 49/149

(under the class definition) Device wherein the closure is mounted for two or more distinct opening and closing movements, used interchangeably and optionally by the user, and wherein different or additional mounting means are provided for the several movements, e.g., structures in which the closure may be adjusted vertically to permit the passage of small animals and may either be moved in this adjusted position to form another opening or returned to its original lowered position and then moved. See particularly subclasses 158+ and 190+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

129, for a closure having optional movements in which one of

the movements is from an edge to edge alignment to an offset position with respect to another closure.

208+, for a closure mounted to have a combination of simple movements (e.g., sliding and swinging) in a single opening movement.

382, for a closure having means for mounting the same hinge at different points usually to allow swinging in reversed directions. 453+, for a reciprocating closure having a movable or removable guide to permit removal of the closure from its supporting frame.
