Abstract: The system foresees for each plate (1) an autonomous mechanical structure composed of one section bar (3) connected to a gripper that holds a plate (1) as well as of another section bar (10) and at least two support arms (5, 5?, 6, 6?) hinged upon said section bars (3, 10); the structure is fixed to a section bar (9) that is in turn fixed to the display counter or window near the base of the tank; the support arms (5, 5?, 6, 6?) differ in length; two supports (4, 4?, 11, 11?) are fixed to each section bar (3, 10); said supports constitute the hinge members upon which the ends of the support arms (5, 5?, 6, 6?) fit; each plate (1) can both move in a parallelogram motion with translation parallel to the display counter or window, and open like a casement window using the pin (7) of the shorter support arm (5, 5?) as a pivot; the system also contains a spring closing mechanism and a lock (18).

Abstract: The frame is formed by the joining of four section bars that constitute an upper transom (1.1), a lower transom (1.2) and two mullions (1.3); some section bars (4) are internally attached to both the transoms (1.1, 1.2) and the mullions (1.3); said section bars (4) have some slideways (4.1) where the plates (3, 3?) slide; some plastic washers (5) are attached externally to both the mullions (1.3) and the transoms (1.1, 1.2) which touch the various parts of the furniture avoiding the entrance of insects or dust and contributing to its thermal proof; some retaining elements of the section bar (4) are attached to the upper transom (1.1) to hold the plates (3, 3?); each frame (1, 1?) can be blocked into its maximum opening position thanks to two couples of pins (12, 12?) where one pin (12) of each couple slides in a slit (11.1); said retaining elements consist of flat springs (8) or threaded pins (9).

Abstract: The opening system entails a longitudinal translation and a rotation of plates of a counter or display unit along the customer's side; each plate is fixed to a first bar; the latter is hinged to two supporting arms by pivots and at its turn each supporting arm is hinged to a lower bearing bar by two further pivots; the supporting arms are parallel and the pivots insist on their ends; a gas-actioned piston is connected to a supporting arm; the lower bearing bar is shaped in such a way to house in its section all the moving mechanics of plates; the two supporting arms of each plate in co-operation with each bar on which the plate-holding clamps are attached and the lower bearing arm form a parallelogram-like moving system.

Abstract: An opening system in which the glass doors (1, 2) move longitudinally along a customer's side between a load bearing upper bar (3) and a lower bar (4); one or more glass doors (1) are held by upper holding bar (22) and lower holding bar (23) which have rollers (20, 21) on their inner ends; the rollers (20, 21) slide transversely along the horizontal part of the T-shaped bars used as carriages (18, 19) which are equipped with wheels (9, 14) that slide longitudinally along slideways (6, 7, 11, 12) which have horizontal bases which extend longitudinally. Two slideways (6, 7) are positioned in the load bearing upper bar (3) and their bases are placed at the same height from ground level; the remaining slideways (11, 12) are positioned in the lower bar (4) and their bases are placed at the same height from the ground level too.
