An isolator comprises a manipulation chamber isolated from the external atmosphere, a door for opening and closing a portal formed on the manipulation chamber, a linear guide mechanism for guiding a linear motion of a front-side edge of the door along the portal, and a rotation guide mechanism defining a rotation of the door about an axis coinciding with the front-side edge. The door is closed by positioning the front-side edge at the front side of the manipulation chamber, and the door is opened inward into the manipulation chamber by moving the front-side edge toward the back side while rotating the door about the front-side edge.

An assembly for closing an opening comprising a door panel adapted for sliding movement between an open position and a closed position, a first extendable member located at a first edge of the opening and extendable towards an opposed second edge of the opening, and a second extendable member located at the second edge of the opening and extendable towards the first edge of the opening, and wherein the door panel includes a stop member attached thereto and movable therewith, the location of the stop member defining the limit of movement of the first extendable member towards the second edge of the opening, and the limit of movement of the second extendable member towards the first edge of the opening.

A sliding arrangement, in particular a slide-out device for drawers, sliding doors, etc., includes a sliding piece and a pulling arrangement which can be coupled together by a coupling piece. The pulling arrangement can be placed in a resiliently pretensioned manner in a parking position and can be blocked in the parking position by a locking element. In order to ensure a reliable movement of a drawer or the like into the closure position, the locking element may be locked in the parking position of the pulling arrangement by a bar.
