PREFERRED EMBODIMENT OF THE INVENTION

(5) In the exemplary embodiment shown in FIG. 1 the anti-vibration support system comprises: a lower base consisting of a floating mount (1) and a fixed mount (2), an upper base (3) and; side structures (4a) that relate the upper base (3) to the lower base.

(6) The floating mount (1) forms a resting surface for the apparatus (E) to be protected with possibility of limited movement on three perpendicular axes X, Y, Z.

(7) Said floating mount (1) is supported by lower elastic elements (11) and by side elastic elements (12) arranged between the floating mount (1) and the fixed mount (2). In the example shown, the lower (11) and side (12) elastic elements comprise springs.

(8) On the other hand, the fixed mount (2) is anchored to the ground or other resistant surface, and together with the side elastic elements (12) acts for limiting the lateral movement of the floating mount (1) on the X-Y plane.

(9) The upper base (3) is intended to rest on the apparatus (E) to be protected, and to limit its movement in the vertical direction, preventing it from being released from the floating mount (1) in the event that the support is subjected to strong vibrations, for example, due to an earthquake.

(10) In the exemplary embodiment shown in FIG. 1, the system comprises, on two opposite sides, two side structures (4a) that relate the upper base (3) to the fixed mount (2) of the lower base.

(11) Each of the side structures (4a) comprises two tilted bars (41, 43), in the form of an X, joined together by their intermediate area (44), and attached, at the opposite ends, to the fixed mount (2) and the upper base (3) by damping elements (42).

(12) These side structures (4a) limit the movement of the upper base (3) and the apparatus (E) to be protected in a vertical direction, and also collaborate in limiting its lateral movement.

(13) In said FIG. 1, the apparatus (E) to be protected is computer equipment that has been schematically represented.

(14) In the embodiment shown in FIGS. 2 and 3, the system comprises two side structures (4b) arranged on two opposite sides of the system.

(15) Each of the side structures (4b) comprises: a tilted bar (41) joined at its ends to the fixed mount (2) and to the upper base (3) by damping elements (42); and two auxiliary bars (45) joined respectively, at one end, to the fixed mount (2) and to the upper base (3) by damping elements (46); said auxiliary bars (45) having, at their opposite ends, two ferrules (47) mounted with the possibility of movement on the tilted bar (41).

(16) Each of the auxiliary bars (45) defines with the tilted bar (41) a configuration in the form of a Y that allows a certain relative mobility of the upper base (3), limiting its vertical movement, but without reaching the rigidity of the side structure (4a) of FIG. 1.

(17) As shown in said FIG. 3, in the rest position, the tilted bar (41) and the auxiliary bars (45) of a same side structure 4b are arranged in a coplanar manner.

(18) Once the nature of the invention as well as an example of preferred embodiment have been sufficiently described, it is stated for all pertinent purposes that the materials, form, size and arrangement of the elements described are susceptible to changes, provided these do not involve an alteration of the essential characteristics of the invention that are claimed subsequently.
