    • 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. In an alternative embodiment elements on one level are parallel in one direction, and in the other level elements are parallel in a crossing direction to the direction of the axes of the first elements, providing a structure of increased strength exhibiting increased economy of manufacture. In both side-by-side and in crossing patterns, panels are provided with notches at the overlapping areas, producing panels with the thickness of a single slat element.
    • 提供复合弯曲外观的网格结构由每个具有由围绕纵向轴线重复的波形曲线限定的形状的板条元素形成,波形和幅度确定的波形,每个第一板条元件具有基本上恒定的和常见的 宽度与定义曲线正交。 这样的元件被布置在两层中,其中板条元素的对称轴全部平行,并且在最大点处的一个层中的板条元素的宽度被定位成与另一层上的板条元素的最小点的宽度重叠,并且元件 在重叠的区域连接。 在优选实施例中,元件是木制板条,在其它实施例中,使用其它材料,例如塑料和金属。 选择适合所用材料的连接方法。 在一个替代实施例中,一个水平面上的元件在一个方向上是平行的,而在另一个水平位置,元件在与第一元件的轴线方向交叉的方向上是平行的,从而提供增加的强度的结构,表现出增加的制造经济性。 在并排和交叉图案中,面板在重叠区域处设有凹口,产生具有单个板条元件厚度的面板。

    • A bar grate and the method of making the same. The bar grate includes a reticulated grate made from a unitary flat sheet and a plurality of lengthwise extending and transversely spaced bars fastened thereto within saddles formed during the making of the reticulated grate. The saddles include projecting tab portions which are folded over and retain the bars in the grate so that no additional fastening is required. The method includes the steps of forming a reticulated grate from a flat sheet to provide a plurality of lines of bar receiving saddles, each having integral therewith tab fastening means, and inserting bars into the respective lines of saddles and bending the tabs about the bars to retain the latter fastened to the reticulated grate.
