Abstract
Abstract This invention relates to an antivibratory support comprising at least one solid resilient element interposed between a support bedplate and a support element, wherein it comprises at least one means for applying to at least one of the solid resilient elements a prestress in at least one direction, this means abuts exclusively on at least two of the rigid elements of this support and said means is preferably adjustable and independent of the means for changing the level.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
201 words
An antivibratory support for isolating a vibrating structure from a support body, comprising, in combination: a rigid bedplate arranged to be supported by the support body; a first solid resilient element resting on, and permanently supported exclusively by, said bedplate; a rigid support plate resting on, and permanently supported exclusively by, said first solid resilient element and including means for supporting the vibrating structure; a second solid resilient element resting on, and permanently supported exclusively by, said support plate; a rigid clamping plate resting on said second resilient element and permanently separated from said support plate; and adjustable compression means connected between said bedplate and said clamping plate, and permanently isolated from said support plate, said compression means being operatively associated with at least one of said resilient elements for compressing said element in at least one direction by any selected amount within a predetermined range when said support is supporting the vibrating structure, thereby varying the vibration absorption and insulating characteristics of said support; said support being free of any connection to the support body and said bedplate and clamping plate being permanently isolated from said support plate, and isolated from each other, by said first and second resilient elements.
Claim 2
Dependent Claim
201 words
An antivibratory support for isolating a vibrating structure from a support body, comprising, in combination: a rigid bedplate arranged to be supported by the support body; a first solid resilient element resting on, and permanently supported exclusively by, said bedplate; a rigid support plate resting on, and permanently supported exclusively by, said first solid resilient element and including means for supporting the vibrating structure; a second solid resilient element resting on, and permanently supported exclusively by, said support plate; a rigid clamping plate resting on said second resilient element and permanently separated from said support plate; and adjustable compression means connected between said bedplate and said clamping plate, and permanently isolated from said support plate, said compression means being operatively associated with at least one of said resilient elements for compressing said element in at least one direction by any selected amount within a predetermined range when said support is supporting the vibrating structure, thereby varying the vibration absorption and insulating characteristics of said support; said support being free of any connection to the support body and said bedplate and clamping plate being permanently isolated from said support plate, and isolated from each other, by said first and second resilient elements.
Claim 3
Dependent Claim
28 words
An arrangement as defined in claim 1 further comprising isolating means interposed between said bedplate and the support body for isolating said compression means from the support body.
Claim 4
Dependent Claim
32 words
An antivibratory suppoRt as claimed in claim 1, wherein each resilient element is a coronal plate made of a solid elastomer having annular grooves in its faces applied against said rigid plates.
Claim 5
Dependent Claim
42 words
An antivibratory support as claimed in claim 1, wherein each resilient element is constituted by a plurality of sleeves made of a solid elastomer and a variable number of these sleeves are inserted in housings regularly spaced out in said rigid plates.
Claim 6
Dependent Claim
23 words
An antivibratory support as claimed in claim 1, wherein the said compression means is oriented in a direction substantially perpendicular to said bedplate.
Claim 7
Dependent Claim
18 words
An antivibratory support as claimed in claim 5, wherein said compression means is also oriented in another direction.
Claim 8
Dependent Claim
35 words
An antivibratory support as claimed in claim 5, wherein said compression means connects said bedplate to said clamping plate and is arranged to perform a screwing action in order to move them toward one another.
Claim 9
Dependent Claim
55 words
An antivibratory support as claimed in claim 5, wherein the distance of at least one of said rigid plates from the face opposite its contiguous resilient element is variable in radial direction for causing the portion of said resilient element which is compressed to increase as the amount of compression in the axial direction increases.
Claim 10
Dependent Claim
35 words
An antivibratory support as claimed in claim 8, wherein said at least one rigid plate is flat and at least one face of at least one of the solid resilient elements contiguous therewith is incurved.
Claim 11
Dependent Claim
43 words
An antivibratory support as claimed in claim 7, wherein said compression means is constituted by a plurality of pins passing through the solid resilient element or elements, the head of the nut of these pins abutting on said bedplate and said clamping plate.
Claim 12
Dependent Claim
43 words
An antivibratory support as claimed in claim 7, wherein said compression means is constituted by a tapped ring of contrary pitches and screwed on threaded edges or flanges likewise of contrary pitches, these edges being unitary with said bedplate and said clamping plate.
Claim 13
Dependent Claim
64 words
An antivibratory support as claimed in claim 6, wherein it comprises, in addition to said compression means for applying a compression in a direction substantially perpendicular to the bedplate, an angle-shaped element housed in a complementary recess formed in at least one face of at least one of said solid resilient elements and arranged to be in contact with the rigid plate contiguous therewith.
Claim 14
Dependent Claim
28 words
An antivibratory support as claimed in claim 12, wherein each angle-shaped element is a ring housed in the corresponding groove of a coronal resilient element having corrugated faces.
