FIELD: displaying equipment. SUBSTANCE: stand is made in two versions, each having display column mounted on poles and formed as regular triangular prism. Each side face of prism is defined by hollow side and transverse connecting members of rectangular section, which are rigidly secured one relative to another in each corner of face by means of insert and two fingers. Devices for accommodating information material are made in the form of cassettes, each having two frames of equal size and similar shape. Frames are composed of side and transverse connecting members and coupled one with another to define cavity for receiving information material. Cassettes are provided with devices allowing them to be readily connected with or disconnected from prism faces. According to first version, stand may be dismantled prior for transportation. Each face of prism has equally sized cells adapted for accommodation of cassettes. Two frames are connected at an angle of 120 deg to side connecting members of each prism face to increase the number of cells for cassettes. Device for connecting and disconnecting prism faces has outer projection made on insert and formed as scalene triangle with central opening. Each frame has support adjustable in vertical plane. Fingers are pressed into openings of inserts positioned on tops of each face of prism. Support with two fingers is introduced into one opening of lower insert. Device for connecting cassette to cells has at least two flags with pin and handle. Flags are mounted on side connecting members of one frame. Slots are made in other frame of cassette. Connecting members of prism face cells and of cells of each frame are provided with supporting surfaces for cassettes and slots for receiving cassette flags. According to second version, transportation may be performed without dismantling due to small size of such stand. EFFECT: increased efficiency, simplified construction and wider operational capabilities. 4 cl, 21 dwg= |
