Abstract
Abstract The transformable low drawing-room table of the invention comprises a bearing surface formed by four upper flat rectangular, side by side arranged, elements which are equal to one another, overlapping according to the same direction and suitably hinged on two lower flat rectangular, side by side arranged, elements which are equal to each other and have the same length as the upper flat elements while being each twice the width of one of them. The assembly of said upper and lower flat elements is supported by a pair of bearing M-shaped members each comprising two outer vertical legs integral with slanting central braces forming a "V" and carrying inside an eccentric sliding guide for support arms of the bearing surface. The slide of the arms upwardly in the oblique direction causes the bearing surface to be raised as well as the lower flat elements to be moved away from each other together with the associated upper flat hinged elements overlapping them to a predetermined extent equal to the width of the upper flat elements. Engagements are provided to lock the arms in the raised position. Stiffening means are also provided, which are disposed crosswise under the lower flat elements and which comprise telescopic extension means supporting the upper flat elements.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
255 words
A transformable low drawing-room table comprising four upper flat rectangular, side by side arranged, elements which are equal to one another in length and width, two lower flat rectangular, side by side arranged elements which are equal to each other in length and width and have the same length as the upper flat elements while being each twice the width of one of said four upper flat elements, said four upper flat elements overlap said two lower flat elements, outer elements of said upper flat elements being hinged to said lower flat elements along outer sides, inner elements of said upper flat elements being hinged to said lower flat elements along inner sides, and a pair of independently height adjustable supporting means each supporting two of said four upper elements and one of said two lower elements and each including two central slanting braces forming a "V", each slanting brace includes a groove defining an inner guide a sliding arm guided within said inner guide, an upper end of said sliding arm being integral with a horizontal bracket supporting one of said two said lower elements, locking means for locking each sliding arm in a raised position, and the length of said sliding arm being such that the movement of said sliding arm in an inclined direction causes said sliding arm to be locked and a sideward and outward shift of said lower flat element supported by said arm is allowed to extend to an extent corresponding to the width of an upper flat element.
Claim 2
Dependent Claim
255 words
A transformable low drawing-room table comprising four upper flat rectangular, side by side arranged, elements which are equal to one another in length and width, two lower flat rectangular, side by side arranged elements which are equal to each other in length and width and have the same length as the upper flat elements while being each twice the width of one of said four upper flat elements, said four upper flat elements overlap said two lower flat elements, outer elements of said upper flat elements being hinged to said lower flat elements along outer sides, inner elements of said upper flat elements being hinged to said lower flat elements along inner sides, and a pair of independently height adjustable supporting means each supporting two of said four upper elements and one of said two lower elements and each including two central slanting braces forming a "V", each slanting brace includes a groove defining an inner guide a sliding arm guided within said inner guide, an upper end of said sliding arm being integral with a horizontal bracket supporting one of said two said lower elements, locking means for locking each sliding arm in a raised position, and the length of said sliding arm being such that the movement of said sliding arm in an inclined direction causes said sliding arm to be locked and a sideward and outward shift of said lower flat element supported by said arm is allowed to extend to an extent corresponding to the width of an upper flat element.
Claim 3
Dependent Claim
88 words
A table according to claim 1, wherein each inner guide of said slanting brace is eccentrically disposed in the brace portion facing inwardly with respect to the "V" and is provided adjacent to the respective vertical leg with a widened portion having a shaped bottom, while the lower end of the sliding arm is provided with a portion having a shape complementary to the bottom of said widened portion so as to define said locking means and provide, by reciprocal engagement, locking each arm in the raised position.
Claim 4
Dependent Claim
35 words
A table according to claim 2, wherein the complementary shapes of the arm and the bottom of the widened portion of the inner guide of the slanting brace are in the form of a step.
Claim 5
Dependent Claim
58 words
A table according to claim 1, wherein stiffening means comprising telescopic extension means are provided under and crosswise to the lower flat elements, said extension means being extensible in opposite directions and supporting the upper flat elements when the upper flat elements are turned over about respective hinges connecting the upper flat elements to the lower flat elements.
Claim 6
Dependent Claim
112 words
A table according to claim 4, wherein the table is transformed into a high table when one of the two lower flat elements is raised and the respective upper flat elements overlapped thereto, thus causing the corresponding supporting arms to slide into the inner guides of the slanting braces till said arms are locked by the locking means, the telescopic extension means is withdrawn for supporting the stiffening means, the upper flat elements are turned over about the respective hinges till they come into contact with the telescopic supporting extension means, the other lower flat element is raised to provide a solid and safe table with a raised and widened bearing surface.
Claim 7
Dependent Claim
34 words
A table according to claim 4, wherein the table is transformable into a low drawing-room table with widened bearing surface and a raised central surface by turning over the two upper outer flat elements.
Claim 8
Dependent Claim
38 words
A table according to claim 4, wherein the table is transformable into a piece of furniture having two bearing surfaces at different levels by raising only one half of the table by raising one of the supporting means.
Claim 9
Dependent Claim
64 words
A table according to claim 4, wherein the table is transformable into a writing-desk with associated seat by raising only one half of the table by raising one of the supporting means and by turning over the upper inner flat element of the raised half table, such a writing-desk being extensible by turning over the upper outer flat element of said raised half table.
Claim 10
Dependent Claim
20 words
A table according to claim 4, wherein said slanting braces rest on the floor by means of a ballasted base.
Claim 11
Dependent Claim
67 words
A table according to claim 1, wherein the horizontal brackets are integral with the upper end of the arms sliding into the slanting braces and are hollow so as to contain means able to be telescopically extended in opposite directions for supporting the upper flat elements when the upper flat elements are turned over about respective hinges connecting the upper flat elements to the lower flat elements.
