Abstract
The invention relates to an item of transformable furniture, more particularly to an item of furniture transformable from a chair into a desk and vice versa, from a desk into a chair. The item of transformable furniture comprises a first plate (5) and a second plate (6), linked to each other by a hinge joint (4), where said two plates can rotate respectively round first and second horizontal (2, 3) axes so that the plates can be moved from a first position as seat and back, respectively, to a second position as front panel (17) and worktop (18), respectively, and vice versa. Said plates are linked by said first and second horizontal axes to a supporting construction, which consists of at least three interconnected folding elements (1, 1′, 19).
Claims16
An item of transformable furniture, comprising:
- a supporting construction, comprising three interconnected folding elements, formed as frames and interconnected by couples of hinge joints, where one of the couples of hinge joints can slide with respect to one of the folding elements, with the first and second of the three interconnected folding elements being U-shaped tubular frames, each of which has a middle part and two legs, the respective middle parts defining a first and a second axis and the legs thereof joined together by the couple of sliding hinge joints;
- a first and a second plate, the first plate linked to the first of the folding elements along the first axis and the second plate linked to the second of the folding elements along the second axis;
- and
- a hinge joint that foldably and independently from the folding elements connects the respective plates along a hinge axis,
- such that, in a first position, the first and second plate are arranged as a seat and a back, and, in a second position, the first and second plate are arranged as a front panel and a worktop, the first and second positions achieved by rotation about the respective axes.
An item of transformable furniture, comprising:
- a first plate and a second plate, linked to each other by a horizontal hinge joint;
- a first horizontal axis parallel to an axis of the horizontal hinge joint and associated with the first plate such that the first plate can rotate around said first horizontal axis, and
- a second horizontal axis parallel to the axis of said the horizontal hinge joint and associated with the second plate such that the second plate can rotate about the second horizontal axis,
- where the two plates can rotate around the first and second horizontal axes respectively so that the first plate and the second plate can be moved from a first position as seat and back, respectively, to a second position as front panel and worktop, respectively, and where the second axis is in the form of an elongated element, lying in a horizontal plane, with a bent section, and the second plate, made of a flexible flat element, and serving as back and worktop, is joined to the second axis such that when it is moved from a back position to a worktop position it deforms in shape from a substantially concave form as back to a substantially flat form as worktop and vice versa.
An item of transformable furniture, comprising:
- a seat and a back, connected by a horizontal hinge joint, where the seat and back can rotate respectively around a first horizontal axis and a second horizontal axis so that the seat and back can be moved from a first position as seat and back, to a second position as front panel and worktop, respectively, and vice versa, and
- a supporting construction that consists of at least three interconnected folding elements, where at least two of the folding elements have horizontal sections that form the first and second horizontal axes, and the same two folding elements are connected by hinge joints with a plate, which is attached by hinge joints to the upper end of the two folding elements, such that when the plate is engaged, the relative positions of the two folding elements changes, causing the seat and back to rotate about their respective axes and change from first to second position and vice versa.
