Abstract

Abstract 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.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 75 words
An art instructing apparatus comprising: a base member; a transparent grid carried by said base member and disposed substantially perpendicularly to said base member; a foreground art object positioned on said base member; a background art object; and perspective means coupled with said background art object for positioning said background art object with respect to said foreground art object to simulate various perspective scenes involving both said foreground art object and said background art object.
Claim 2
Dependent Claim 75 words
An art instructing apparatus comprising: a base member; a transparent grid carried by said base member and disposed substantially perpendicularly to said base member; a foreground art object positioned on said base member; a background art object; and perspective means coupled with said background art object for positioning said background art object with respect to said foreground art object to simulate various perspective scenes involving both said foreground art object and said background art object.
Claim 3
Dependent Claim 39 words
An apparatus as in claim 1 wherein said means for positioning said background art object includes means for controlling the angle at which the scene comprising said foreground art object and said background art object recedes to the horizon.
Claim 4
Dependent Claim 35 words
An apparatus as in claim 1 wherein said means for positioning said background art object includes means for controllably positioning the horizon in the scene comprising said foreground art object and said background art object.
Claim 5
Dependent Claim 21 words
An apparatus as in claim 3 wherein said foreground art object is adapted to be selectively positioned on said base member.
Claim 6
Dependent Claim 40 words
An apparatus as in claim 4 wherein said base member includes a ferromagnetic portion and wherein said foreground art object includes a pedestal having a magnetic portion whereby said foreground art object can be selectively positioned on said base member.
Claim 7
Dependent Claim 15 words
An apparatus as in claim 5 wherein said foreground art object comprises a figure model.
Claim 8
Dependent Claim 30 words
An apparatus as in claim 1 wherein said perspective means includes a rod disposed perpendicularly to said base member and a cord interconnecting said rod with said foreground art object.
Claim 9
Dependent Claim 34 words
An apparatus as in claim 1 wherein said perspective means includes first and second rods disposed perpendicularly to said base member and a plurality of cords interconnecting said rods with said foreground art object.
Claim 10
Dependent Claim 12 words

Dependent Claim 14 words
An apparatus as in claim 11 wherein the separation between said rods is adjustable.
Claim 14
Dependent Claim 21 words
An apparatus as in claim 12 wherein said transparent grid is disposed substantially at the front edge of said base member.
Claim 15
Dependent Claim 15 words
An apparatus as in claim 13 wherein said transparent grid is disposed within mounting brackets.
Claim 16
Dependent Claim 12 words
An apparatus as in claim 14 wherein said grid includes diagonal lines.
Claim 17
Dependent Claim 16 words
An apparatus as in claim 15 including an adjustable horizontal reference marker carried by said grid.
Claim 18
Dependent Claim 20 words
An apparatus as in claim 16 wherein said adjustable horizontal reference marker comprises first and second clips and a cord.
Claim 19
Dependent Claim 32 words
An apparatus as in claim 14 wherein said transparent grid, said foreground art object, said background art object and said first and second rods are adapted to be disassembled for compact packaging.
