FR2823899A1 - Text/schematics/geographic card lecture support unit having paper roll lit lighting system board area placed low power low speed motors activated moving left/right and controlled locally/remotely. - Google Patents

Abstract

The lecture support unit has a paper roll (3) lit by a lighting system (5) engaging a board area and activated by two motors (M1,M2). The engagement motor axes (1,2) engage the drawing paper to the left or right and the motors are low power and low speed and controlled locally by four push buttons or from a remote control.

Description

- 1 The present invention relates to a device for supports

  educational (texts, diagrams, geographical maps, cadastre, etc.), the change of figures being made by

  winding controlled locally or remotely.

  Thanks to this new scrolling educational support, you can: _ Prepare educational or informative sessions in advance (texts, diagrams, maps), which allows the speaker or professor to be more available to their

audience or class.

  / Easily return to what was written during a session, and thus revise or re-explain certain points, keep track of what has been done during the sessions

  Previous É. It promotes participatory education.

  The device has a first upper horizontal axis (1) and a second axis

lower horizontal (2).

  The upper axis is driven by a motor (M1), the lower axis is driven by a

second engine (M2).

  _ S The first motor is controlled in both directions by a box with two push buttons. The second motor is also controlled in both directions by a second box with two push buttons. The motor controls can be replaced by a single box with four pushbuttons, a remote control, remote-controlled or co mm a nd nu merquem ent by a small table fixed on the front of the device itif and

  G stopping by a signal given by a cell.

  The upper axis (1) drives a sheet of drawing paper (3), the standard width of the drawing paper for plotter being 92cm or different widths. The lower axis (2) receives the same sheet of drawing paper (3). The upper axis turning clockwise drives the paper roll upwards. The lower rotating axis

  : counterclockwise draws the drawing paper roll down.

  To avoid tearing the paper, the drive motors are of low speed and low power. The main switch allows the simultaneous supply of the two motors (M1) and (M2). Two adjustable limit switches allow to stop the

unwinding of the paper.

  3o The motors (M1) and (M2) must be of the same power and the same speed, but may have different characteristics than those installed at present and without end of

  run to unwind a longer roll of paper.

  The realization of the diagrams on the paper (3) can be carried out manually using the board (4) adjustable in vertical position or inclined using rulers, compass, 3 pencils, markers before the installation of the paper on the axes or either by computer at

  from a computer, software, scanner and inkjet plotter.

  A neon tube (5) embedded in the upper part improves the visibility of diagrams, texts for students. This neon tube can be turned on or off with a simple switch (ECL), this lighting system can be made up of several tubes at

  Q'a neon horizontal or vertical, or by bulbs or spotlights.

  Behind the drawing sheet is fixed a white drawing board (4), pivoting which allows to draw manually in vertical or inclined positions and which can receive

images from an overhead projector.

  This educational unfolding device mounted on four wheels is easily

  mobile and can be moved anywhere in the room or from one room to another.

  To consolidate the educational support in the lower part, a horizontal chest (6) can receive the power supply and the storage of equipment: rolls of paper,

your markers, pencils.

  An axis (7) allows you to store a roll of paper and unroll it properly.

  Two guides (8) fixed on the board (4) allow to support a designer's tee

  or a ruler for drawing horizontal or vertical lines.

  A second vertical box, on the right or left of the device or on both sides, can be fitted to receive the power supply and serve as storage, and a second device juxtaposed with the second vertical support can be built, fixed by

  hinges or by tube, and therefore remaining aligned or offset slightly rounded.

Claims (4)

  1) Educational support device characterized by a paper roll (3) lit by a lighting system (5) which is wound or unwinding in front of a drawing board (4), the roller is activated by two horizontal axes driven by two motors (M1) and (M2),   respectively one in the upper part and the other in the lower part of the board.   2) Device according to claim 1 characterized in that the drive motors of the axes (1) and (2) entrain the drawing paper, these motors can be fixed to the right or left of the support are of low power and small speed, controlled locally (a single box with four push buttons or two boxes with double push buttons) or remotely by remote control or digitally controlled from a small table fixed on   the front of the device and stopping by a signal given by a cell.   3) Device according to any one of the preceding claims, characterized in that   it has a second vertical box built to the right or to the left of the support   educational to receive power and serve as storage.   4) Device according to any one of the preceding claims, juxtaposed with a   second support, these two supports having a common central axis (vertical box common to both) fixed by hinges or by tube, and therefore remaining aligned or offset, slightly in rounding.   ) Device according to claim 1, characterized in that the lighting system consists of one or more neon tubes and can be replaced by two neon tubes
