Abstract: A device for powering interactive appliances in moving playground equipment includes an electrical generator mounted onto the moving element of the playground equipment, characterized by the design of the electrical generator, which includes a case (1) inside of which there is fixed a tube (7) made out of insulating material, on the tubes periphery surface there are fixed n number of coils (4). n is greater or equal to one. The coils (4) are divided from each other by separating insolating elements (3). Inside the tube it is placed a permanent cylindrical magnet (5) allowing for its sidestep movement along the tube. At the two ends of the tube (7) there are fixed rebound elements (6) The terminals of single coils or a group of connected coils (4) are terminals of the powering device, connected to the interactive appliances.

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).

Abstract: The invention relates to an item of transformable furniture, in particular to a chair that transforms into a desk and vice cersa. An item of transformable furniture consisting of two substantially flat elements (5) and (6) connected with each other, which can switch over between a first position as a seat (6) and a back (5) and a second position as a front panel (6) and a worktop (5) and vice versa. The item of transformable furniture is provided with a supporting construction for the two substantially flat elements (5), (6). The supporting construction consists of two linked lateral vertical elements (1) located at a distance from one another, where the two substantially flat elements are located between the two linked lateral vertical elements (1).
