Abstract: A wall board includes a board support mechanism which is adapted to be secured to a vertical wall surface and a board member which is vertically movably supported on the board support mechanism. The board support mechanism includes an arrangement which counterbalances the weight of the board member. Laterally spaced, vertically extending side walls extend rearwardly from the board member on opposite sides of the board support mechanism to locations adjacent the vertical wall surface. The inner sides of the side walls have vertically extending guide rails which receive guide slides or guide rollers provided on the board support mechanism.

Abstract: A construction set for the manufacture of frames for furniture, such as display cabinets, showcases and the like, having base profiles and enlargement profiles, wherein the base profiles have on their front viewing side a closed viewing surface and on their back side a profiled connecting edge. The enlargement profiles also have a profile connecting edge which can be connected to the connecting edge of the base profile. The enlargement profiles have, on both oppositely positioned longitudinal edges, respective connecting edges which are constructed mirror-inverted to one another and are also constructed the same as the connecting edges on the base profiles. The construction set also includes connecting profiles insertable between two closely opposed connecting edges such that the inserted connecting profile clamps together the adjacent base and/or enlargement profiles whose connecting edges oppose one another.
