  • Lattice structure formed from curved elements
    Patent number: 5555692
    Abstract: A latticework structure providing a composite curved appearance is formed from slat elements each having a shape defined by a waveform curve repeating about a longitudinal axis, the waveform defined by a wavelength and a magnitude, each of the first slat elements having a substantially constant and common width orthogonal to the defining curve. Such elements are arranged in two levels with axes of symmetry of the slat elements all parallel, and the width of slat elements in one level at maxima points positioned to overlap the width of minima points of the slat elements on the other level, and the elements are joined at the areas of overlap. In a preferred embodiment, the elements are wooden slats, and in other embodiments other materials are used, such as plastic and metal. Joining methods are selected appropriate to the materials used.
