Abstract

A drawing apparatus for accurately generating a hand-drawn reproduction of an image or object is provided. The drawing apparatus includes a mirror and reflective filter arrangement that allows a user to view, through a single eyepiece, both the object being reproduced and the drawing surface where the user generates a hand-drawn reproduction of the viewed drawing object. In one embodiment, the apparatus includes an adjustable, angled stand for supporting the drawing object, and a drawing surface for generating hand-drawn reproductions. As viewed through the single eyepiece, an image of the drawing surface appears superimposed on the drawing object being reproduced. In further embodiments, the single eyepiece is used with a selectable filter arrangement for adjusting the amount of focus on the drawing surface and/or drawing object.

First claim

The invention claimed is:

1. A drawing apparatus comprising:
a first support having a first surface and an eyepiece, wherein at least a portion of the first surface comprises a mirrored surface;
a reflective component coupled to the first support, the reflective component comprising at least one reflective filter and at least one tinted filter;
a second support hingedly attached to the first support, the second support comprising at least one drawing surface; and
a third support hingedly attached to the second support, the third support configured to support the at least one drawing object,
wherein the at least one drawing surface and the at least one drawing object are simultaneously viewed through the eyepiece via the reflective component,
wherein the at least one tinted filter is selectively positionable with respect to the reflective component,
wherein when the tinted filter is in a first position relative to the reflective component, the drawing surface is in greater focus than the drawing object,
wherein when the tinted filter is in a second position relative to the reflective component, the drawing object is in greater focus than the drawing surface, and
wherein the tinted filter is in a second position when only the reflective filter is viewed through the eyepiece.

2. The drawing apparatus of claim 1 , wherein the tinted filter is in a first position when a surface of the tinted filter is parallel to a surface of the reflective filter such that both the reflective filter and the tinted filter are viewed through the eyepiece.

3. The drawing apparatus of claim 1 , wherein the drawing surface is viewed through the eyepiece based on reflection of the drawing surface by the mirrored surface and the reflective filter.

4. The drawing apparatus of claim 1 , wherein the drawing object is viewed through both the eyepiece and the reflective filter.

5. The drawing apparatus of claim 4 , wherein the drawing object is further viewed through the tinted filter.

6. The drawing apparatus of claim 1 , wherein the drawing apparatus is configured to adjust between an open position and a collapsed position.

7. The drawing apparatus of claim 6 , wherein the first support and the third support are adapted to fold towards the second support when the drawing apparatus is in a collapsed position.

8. A drawing apparatus for reproducing at least one drawing object on a drawing surface, the drawing apparatus comprising:
a first support comprising an eyepiece, a mirror on a first surface of the first support, and a reflective component, wherein the reflective component comprises a reflective filter and a tinted filter;
a second support coupled to the first support, the second support comprising at least one drawing surface; and
a third support coupled to the second support, the third support configured to support the at least one drawing object,
wherein the at least one drawing object and the at least one drawing surface are simultaneously viewed through the eyepiece from a second surface of the first support,
wherein the tinted filter is selectively positionable between at least a first position and a second position relative to the reflective filter, and
wherein the tinted filter is in the second position when only the reflective filter is viewed through the eyepiece, wherein when the tinted filter is in a second position, the drawing object is in greater focus than the drawing surface.

9. The drawing apparatus of claim 8 , wherein the at least one drawing surface is viewed through the eyepiece based on reflection of the at least one drawing surface by the mirrored surface and the reflective filter.

10. The drawing apparatus of claim 8 , wherein the at least one drawing object is viewed through the eyepiece and the reflective component.

11. The drawing apparatus of claim 8 , wherein the tinted filter is in the first position when a surface of the tinted filter is parallel to a surface of the reflective filter such that both the reflective filter and the tinted filter are viewed through the eyepiece, wherein when the tinted filter is in a first position, the drawing surface is in greater focus than the drawing object.

12. The drawing apparatus of claim 8 , wherein the drawing apparatus is adapted to collapse into a folded configuration.

13. A drawing apparatus comprising:
a first support comprising an eyepiece, a mirror, and a reflective component, wherein the reflective component comprises a reflective filter and a tinted filter, wherein the tinted filter is selectively positionable with respect to the eyepiece between at least a first position and a second position relative to the reflective filter, and
wherein the tinted filter is in the second position when only the reflective filter is viewed through the eyepiece,
and further wherein when the tinted filter is in a second position, the drawing object is in greater focus than the drawing surface;
a second support coupled to the first support, the second support comprising a drawing surface; and
a third support coupled to the second support, the third support configured to secure the at least one drawing object,
wherein the drawing surface and the at least one drawing object are simultaneously visible to a user through the eyepiece, wherein the at least one drawing object is directly viewed via the eyepiece and the reflective filter, and further wherein the drawing surface is indirectly viewed via the eyepiece and the mirror.
