Abstract
Abstract Disclosed herein is a reducible volume desk, or in other words, a desk whose volume can be reduced with the utmost ease so that, at the time it is being transported, it takes up the least possible space. Subsequently, in an extremely short period of time, the desk can be reassembled in its final configuration with the certainty that all of its component parts are available. The desk is essentially composed of a first member, or support platform, to the underneath part of which are connected two second members that define the lateral walls and a third cross member perpendicular thereto; the said second and third members being foldable, one on the other, in parcel form, on the lower surface of the support platform.

A reducible volume desk comprising a first member (1) which acts as a support platform; two second members (2) connected perpendicularly to the aforementioned first member to define two parallel walls supporting the first member; and a third member (3) which acts as a wall and is connected to the lower surface of the support platform and, perpendicularly, to the above-mentioned second members; said second and third members being foldable, one on the other, in parcel form, on the lower surface of the support platform; and wherein said third and the said second members are conected by hinges to the lower surface of the support platform in such a way that said third member can be folded, in parcel form, on the lower surface of the support platform and that said second members can be folded onto the previously folded third member, the connection between said third and said second members being removable; and wherein each said hinge connecting the second members to the support platform includes: a first body (11), virtually of "L" shape, a first flange (13) of which is fixed integrally to the lower surface of the support platform of the desk; and a second body (12), virtually of "L" shape, a first flange (14) of which is fixed integrally in a notch provided for this purpose in the upper border of one of said second members, said first flanges of said first and second body being arranged parallel to one another and second free flanges (15) and (16), respectively, being parallel and adjacent; said second body being provided, at a point corresponding to where the first flange (14) joins with the second free flange (16), with a slot (17) inside which is inserted, in a complementary fashion, an extremity of the free flange (15) of said first body; a hinge connection pin (18), the axis of which is parallel both to the plane of said first member and to that defined by said second member, passing through the first flange (14) of the second body (12) in a direction toward the second flange thereof and into a vertex of said extremity of the free second flange (15) of the first body and through said slot (17), the distance the axis of said pin is away from the lower surface of the support platform being no less than the thickness of said third member.

A reducible volume desk comprising a first member (1) which acts as a support platform; two second members (2) connected perpendicularly to the aforementioned first member to define two parallel walls supporting the first member; and a third member (3) which acts as a wall and is connected to the lower surface of the support platform and, perpendicularly, to the above-mentioned second members; said second and third members being foldable, one on the other, in parcel form, on the lower surface of the support platform; and wherein said third and the said second members are conected by hinges to the lower surface of the support platform in such a way that said third member can be folded, in parcel form, on the lower surface of the support platform and that said second members can be folded onto the previously folded third member, the connection between said third and said second members being removable; and wherein each said hinge connecting the second members to the support platform includes: a first body (11), virtually of "L" shape, a first flange (13) of which is fixed integrally to the lower surface of the support platform of the desk; and a second body (12), virtually of "L" shape, a first flange (14) of which is fixed integrally in a notch provided for this purpose in the upper border of one of said second members, said first flanges of said first and second body being arranged parallel to one another and second free flanges (15) and (16), respectively, being parallel and adjacent; said second body being provided, at a point corresponding to where the first flange (14) joins with the second free flange (16), with a slot (17) inside which is inserted, in a complementary fashion, an extremity of the free flange (15) of said first body; a hinge connection pin (18), the axis of which is parallel both to the plane of said first member and to that defined by said second member, passing through the first flange (14) of the second body (12) in a direction toward the second flange thereof and into a vertex of said extremity of the free second flange (15) of the first body and through said slot (17), the distance the axis of said pin is away from the lower surface of the support platform being no less than the thickness of said third member.
