摘要:
A refrigerated cabinet with one or more self-closing doors, comprising a support frame (2), which defines a load compartment 3, and at least one door (10) for closing the load compartment. The door is hinged to the frame with a vertical rotation axis (X) and may rotate to move between a closed position and a predefined position of maximum opening. The cabinet comprises an automatic door closing system, which comprises a hydropneumatic piston (40). The piston is hinged to the door in an offset position with respect to the rotation axis by means of a lever extension (43) integral with the door. The two hinging points of the piston are positioned with respect to the rotation axis so that: the hydropneumatic piston exerts a force (F) which always develops an angular momentum (M) for closing the door about the rotation axis, and the perpendicular distance (B) between the dynamic action axis (Y) of the piston and the rotation axis (X) decreases as the degree of angular opening of the door increases.

A safety cabinet includes an enclosure having a double-walled construction and a pair of doors to selectively seal the enclosure. The safety cabinet can be used to store, for example, flammable liquids, flammable waste, corrosives, pesticides, or combustible waste. The safety cabinet incorporates a sequential door-closing system that sequentially closes the doors of the safety cabinet in a predetermined order.

A skylight or roof hatch that is manually opened and closed. The skylight has one or more hinges allowing it to open and close and it also has one more gas springs that exerts constant force against the window urging the window into an open position. The window is closed to overcome the biasing force exerted by gas springs by winding in a cable that is connected to the window. A single pulley wheel that is mechanically linked to other mechanical elements is utilized to spool in cable in order to close the window and to unlock a reel lock to allow for automatic opening of the window.

The sash (2) of the window is connected with the frame (1) by means of a hinge device including a set of pivot hinges (12) defining a hinge axis of the window. The hinges are mounted in such a position that the hinge axis is situated between a centre line of the window and the top or bottom of the window. The window is provided with a least one auxiliary opening device comprising at least one pressure medium operated cylinder (124) with an operating rod (123). At least one hinge comprises check means restricting the movement of the window.
