1. Apparatus comprising:

  • a pair of primary, opposite frame members;

    a pair of secondary, opposite frame members, said frame members being disposed to define a substantially rectangular frame;

    web means elastically disposed within said frame and attached at its periphery to each member of each of the pairs of frame members;

    linking means pivotally attached to each frame member at each corner of the two pairs of members so as to hold the secondary members substantially at right angles to the primary members;

    wherein the pivots at the ends of each secondary member are disposed such that increasing the spacing between the primary members swings the linking means so as to increase the spacing between the secondary members, thereby to stretch the web in orthogonal directions.
