A non-sliding spring mechanism for picture and poster frames. A flat metal spring biasing member having a pair of opposed sawtooth or irregular edges is positioned between a rotating cover member and a stationary base member in each section of the frame device. The projections on the irregular edges of the spring members are preferably pointed and embed in the metal channels of the cover and base members and dig grooves therein, preventing the cover member and base member from sliding longitudinally relative to one another. Various configurations of toothed and pointed members can be utilized on the opposed irregular edges of the spring biasing member. Preferably, the irregular edges have one or more flat areas in order to prevent the spring members from embedding too deeply in the channels in the cover and base members.
