Abstract
A tracing an object has front and rear shells that are pivoted to each other to form a case. The rear shell defines a platform for supporting an object and the front defines a clear window pane forming a tracing plane through which the object is visible. A leg connected between the shells supports the front shell at an open position. A support movably mounted to the front shell carries a view port to view the object through the window pane and to trace an image of the object on the tracing plane.
Claims15
A tracing device for tracing an object, comprising:
- a rear member in the form of a rear shell and defining a platform for supporting an object to be traced;
- a front member pivotally mounted to the rear member and having a clear window pane defining a tracing plane, through which the platform, and an object supported on the platform are visible;
- positioning means connected between the rear member and the front member for supporting the front member in at least one open position with respect to the rear member for defining an enlarged object space between the platform and the window pane, the positioning means comprising a support leg;
- a support structure movably mounted to the front member for movement between a stored position and a viewing position;
- means defining a view port at a location on the support structure for viewing the platform and an object on the platform, through the view port when the support structure is in the viewing position so that an image of the object on the platform can be traced at the tracing plane of the window pane;
- and
- a drawer slidably mounted into and out of the rear shell, the support leg being pivotally mounted to the drawer so that the drawer slides out of the rear shell when the front member raises to the open position.
