Art instructing apparatus
专利汇可以提供Art instructing apparatus专利检索，专利查询，专利分析的服务。并且This art instructing apparatus allows the art student to compose his own three dimensional scene for reproduction in two dimensional form. The apparatus affords particular assistance to the student in the handling of perspective views. The rate at which the three dimensional scene recedes from the foreground to vanishing points in the background is graphically defined by four elastic cords attached to a pair of spring clips carried by two vertical rods at the rear of the apparatus and to a figure model, which serves as a foreground art object. An elastic cord extends from each spring clip to the top of the foreground figure model, and an elastic cord extends from each spring clip to the bottom of the foreground figure model. The spring clips can be vertically positioned on the rods to set the vertical position of the horizon relative to the foreground figure model. The horizontal separation of the vertical rods is also adjustable to adjust the rate at which the perspective lines, defined by the four elastic cords, approach the vanishing points. Additional figure models are provided for attachment to the elastic cords such that a three dimensional scene, including both foreground and background figures, can be composed. A transparent grid is provided at the front of the apparatus to assist the student in reproducing the proportions of the various models. The foreground figure model stands on a magnetic base or pedestal which can be selectively positioned on the base of the apparatus to provide the art student maximum flexibility in composing the three dimensional scenes he wishes to reproduce. This art instructing apparatus is designed for easy disassembly so it can be conveniently and compactly transported.，下面是Art instructing apparatus专利的具体信息内容。
