The tvvo substantially flat elements upon svvitching over from a first position to a second position and vice vērsa fall essentially in the same planē.
A preferable embodiment of the chair provides two connected substantially flat elements mounted on a supporting construction, consisting of tvvo linked lateral vertical elements, located at a distance from one another. In the space limited by the tvvo lateral vertical elements there are arranged tvvo substantially flat elements. In the form of a chair the first substantially flat element of the fumiture forms a back, vvhereas in the form of a desk the first substantially flat element moves in another substantially horizontal position vvhere it forms a vvorktop. In the form of a chair the second substantially flat element of the fumiture forms a seat, vvhereas in the form of a desk the second substantially flat element moves in another substantially vertical position vvhere it forms a front panei of the desk.
In another preferred embodiment of the invention, the supporting construction has tvvo parallel horizontal axes located at different Ievels, said axis being fixed permanently to tvvo lateral vertical elements. The tvvo substantially flat elements are linked vvith a hinge joint vvhose axis is parallel to the horizontal axes. The first substantially flat element is connected vvith the top horizontal axis by means of a slot, or a mechanism vvhich enables the substantially flat element to make a rotating and translation movement against the axis. The second substantially flat element is connected vvith the bottom horizontal axis, whereby the latter goes through the former, or the flat element lying on top of the axis, or by means of a mechanism vvhich enables the substantially flat element to make a rotating motion against the axis. In an altemative option, the second substantially flat element is connected vvith the bottom horizontal axis by means of a slot, or a mechanism, whereby the second substantially flat element makes a rotating and translation movement against the bottom horizontal axis, vvhile the first substantially flat element is connected vvith the top horizontal axis, whereby the axis goes through the substantially flat element, or the substantially flat element lies on top of the axis, or by means of a mechanism, aliovving the substantially flat element to make a rotating movement against the axis. In the transformation from position chair into position desk, from its vertical or nearly vertical position, the first substantially flat element-back is positioned in horizontal or nearly horizontal position as a desk top, vvhile the second substantially flat element-seat, from horizontal or nearly horizontal position, is positioned into vertical or nearly vertical position as a front panei.
In the form of a chair the first substantially flat element and the second substantially flat element of the fumiture preferably form an angle betvveen 80° and 130°, more preferably an angle betvveen 100° and 105°. Here the bottom horizontal axis connects the two lateral vertical elements in a place that determinēs the height of the position of the second substantially flat element, vvhich is a seat, in relation to the floor.
In the form of a desk the first substantially flat element and the second substantially flat element of the fumiture preferably form an angle between 80° and 130°, more preferably an angle between 100° and 105°. Here the top horizontal axis connects the tvvo lateral vertical elements in a place that determinēs the height of the position of the first substantially flat element, vvhich is the desk top, in relation to the floor.
According to a stili preferred embodiment one of the horizontal axes can consist of tvvo half-axes mounted on the substantially flat element.
In the process of transformation the hinge joint ensures a smooth change of the position of the two substantially flat elements in relation to each other: increasing the angle formed betvveen the substantially flat elements, and vice vērsa. In the process of transformation the slot ensures the translation movement of the substantially flat element it is located in, or vvhich contains the mechanism, respectively, in relation to the respective horizontal axis during the rotation of each substantially flat element around the horizontal axis connected vvith it, and the transition of the substantially flat element from vertical or nearly vertical position in horizontal or nearly horizontal position, and vice vērsa. In the form of a chair the axis of the hinge joint is on the same or nearly the same Ievel with the bottom horizontal axis. During the transformation into a desk, the axis of the hinge joint moves to one and the same or nearly the same Ievel vvith the top horizontal axis. The positions of the top and bottom horizontal axes remain unchanged.
The tvvo lateral vertical elements can be optionally formed as frames having closed or open contour. The lateral vertical elements can be formed in any other suitabie geometric shape, preferably as a panel-like lateral elements. The lateral vertical elements can be made of mētai, plastic, medium density fibre board (MDF), solid vvood, plywood, solid HPL, or other suitabie material; their construction can be non-dismountable or dismountable.
