DEFINITION

Classification: 160/188

(under subclass 181) Devices in which there are means (including counterbalance means) to either (1) cause motion of one or more of the strips, slats or panels relative to others of the unit, (2) cause motion of the unit or some portion thereof relative to the support or mounting means or (3) both. The operating means must be more than a mere hand hold or handle.

(1) Note. Means to force the unit against its support or against portions of the structure having an opening to be closed by the unit are not considered operators but are in appropriate coordinate subclasses below, e.g., subclass 209.

SEE OR SEARCH THIS CLASS, SUBCLASS:

181+, for the combination with operating means for the particular types of devices there provided for.

218+, for the structure of the unit both with and without means to cause relative motion of the strips, slats or panels where no supporting or mounting means are claimed.
