Board describing or showing reality in four dimensions, a universal plotter and a scientific measurement and learning tool

Abstract

The present invention relates to a metal-sheet board or blackboard with magnetic features having two or three movements, which plots and represents reality in four dimensions (horizontal, vertical, depth and time) and which describes reality objectively, in which a T-shaped ruler is moved on a rail along the horizontal or X axis by a digital stepper motor controlled by a driver and software on the computer (horizontal movement). Furthermore, a tool truck surrounding the T-shaped ruler moves along the entire length (vertical movement) or Y axis thereof, actuated by a digital stepper motor controlled by a driver, which is in turn controlled by software on the computer, with these two movements controlled by mathematical speed and acceleration functions. A felt-tip pen or marker is placed in the tool truck against the surface of the blackboard in order to plot all manner of FIGURES. Furthermore the tool truck includes a third motor providing movement perpendicular to the blackboard (depthways), together with the respective motor and driver thereof. Different scientific measurement tools and structures are mounted on the board or the tool truck and connected electronically to the different data input or output pins available on the blackboard by means of the driver and the related software on the computer, providing a real scientific measurement and laboratory instrument that interacts with the computer.

1 . A board having movements in a horizontal axis, a vertical axis and a depth axis that draws, makes measurements, and interacts with a computer, for providing three-dimensional constructions, comprising:
 a first means for movement across the entire length of the horizontal axis configured for moving a T-shaped ruler;   a second means for movement, adjacent the T-shaped ruler, configured for moving a tool holder carriage across the entire length of the vertical axis; and   wherein the first means for movement and the second means for movement are respectively actuated by a first digital engine and a second digital engine both instructed by mathematical functions of velocity and acceleration and, respectively, handled by at least one driver wherein the at least one driver is controlled by a software from the computer for travelling over an entire surface of the board for describing slopes and parabolas.   
     
     
         2 . A board according to  claim 1 , comprising a tool holder carriage that displaces across the entire panel surface, having mechanisms of subjection of various instruments or tools. 
     
     
         3 . A board according to  claim 2 , comprising any type of tracer in the tool holder carriage, that is actuated against the board through a electromagnetic mechanism controlled from the software and with the respective horizontal and vertical movements, could make all kind of graphics, draws or paintings on the board, paper, canvas or another surface. 
     
     
         4 . A board according to  claim 3 , comprising a third means for movement across the entire length of the depth axis actuated by a third engine mounted in the tool holder carriage handled by the at least one driver from the software on the computer. 
     
     
         5 . A board according to  claim 2  comprising, measurements tools, visualization screen, power terminal blocks, mechanisms, and sensors in the surface or in the tool holder carriage which are connected to the input and/or output data legs to disposition of the respective controllers that interact with the software from and to the computer. 
     
     
         6 . A board according to  claim 5  comprising, a metallic plate for rotating the panel over its horizontal axis, getting different positions and maintaining the constructions and magnetized mechanisms attached to it. 
     
     
         7 . A board according to  claim 1 , characterized by displacing a T-shaped ruler across the horizontal on a rail (steel tube) where there are two pairs of pulleys fixed embracing it. 
     
     
         8 . A board according to  claim 1 , characterized by starting the movements of the horizontal axis and the vertical axis across a cable that wraps a turn and a half a double lane pulley, that is mounted on a digital engine and tied to its movements through a key joint, the cable goes to the other end and passes through the free pulley, a one lane pulley, then returns and ties the T-shaped ruler and goes out and returns again to the dragging pulley, this mechanisms also works for the Z axis o depth axis. 
     
     
         9 . A board according to  claim 9 , distinguished by putting onto the rail the cable that wraps in a turn and a half the double lane pulley, placing from outside of the pulley two entrainment pins that make it follow the desire trajectory for the cable not to mount.
