Description

The invention relates to moving diagrams with the use of endless ribbons arranged in parallel rows and moved on the main board along its direction. In the proposed mobile diagram, in order to better shade the data on the data tapes, the gaps between the tapes are covered with strips of a grid located above the tapes.

In a modification of the invention, two groups of infinite ribbons are applied, between which there is a transverse band serving as a zero line for quantities that are set in the marked groups of ribbons.

In FIG. 1 shows a front view of a moving diagram in the form of a flat table; FIG. 2 is a section along the line P - II in FIG. one; FIG. 3 is a partial section along the line III-III in FIG. one; FIG. 4 and 4 are a view of the upper and lower edges of the base board serving as a base, which are circumscribed by ribbons; FIG. 5 shows a section along the line V - V in FIG. four; FIG. 6 is a front view of a modified mobility chart; FIG. 7 is a section along line VII-VII in FIG. 6

The device (Figs. 1-5), in the form of a flat table, consists of three boards or plates, namely, from the bottom board 1, the middle board or the base 2 of the top plate 3. Both longitudinal ribs of the middle plank 2 envelope with endless ribbons 4, half of which are colored in one, for example, black, and half in the other, for example, white. When guiding ribbons 4, when they are longitudinally displaced, they are narrow bulging along the S board of the middle board 2. For greater reliability, the ribbons on the middle board 2 edges of the latter, which bend around the ribbons, can be provided near the upper edge of the board with corresponding cuts b displaced relative to each other. The bottom edge of the board can be provided with notches 7 (Fig. 4) along the width of the ribbons 4. Both transverse edges 2 of the middle board 2 can also protrude forward with respect to the plane of the board 2 (Fig. 3). The bottom board 1 is completely flat, and only its transverse edges 1 protrude with their surfaces forward (Fig. 3), adjacent to the edges 2 of the middle board 2, which ensures the relative position of the boards 2 and 1. The lattice 3, completely flat, has the shape of a frame and consists of two transverse fields 3, the lower field 3 and the upper field 3 (Fig. I). Kra all

adjacent planks or plates 1, 2 and 3 are connected by a sleeve, with various rivets 8, the upper pair of which serves at the same time for suspending the entire device.

The grille 3 consists of a series of vertical strips 9, the number of which corresponds to the number of individual strips 4. The strips 8TI adjoin the convexities of the strips 5 of the middle plank 2 and separate one tape from the other from the outside. The entire outer surface of the table, including the strips 9, can be made black so that the installed white parts of the strips 4 clearly stand out against a black background, or vice versa. The upper field of the grille 3 is provided with pockets 10 in an amount equal to the number of tapes 4 for placing or sticking cards with data on the values shown by the respective tapes, and these karyanchiki are closed with a hinged lid 11.V

In addition, along the upper field of the grid 3 and the middle board 2 located below it, there are a number of holes 12 above each Tape 4 serving to insert special marking sticks 13 (Fig. 1).

In order to move the tapes 4 from top to bottom, on each of them there is, on the border between the black and white parts, a transverse thickening 14. Instead of these thickenings, the tape can be provided with holes 14, in which a stick is stuck to move the tape.

The proposed moving diagram can be used as follows. The values related to a particular heading 10 are indicated by the appropriate tape installation; if any of the rubrics should be highlighted, then a marking stick 13 is stuck in the corresponding hole 12 above it.

The modified moving diagram (Figs. 6 and 7) is intended to indicate positive and negative values.

in the vertical row of each rubric. For this, the lattice by the transverse strip 15, which represents the zero line, is divided accordingly into two parts. Here, in each vertical heading of the table, there are two tapes 4 and 4, which are passed through the slots in the board 2 on both sides of the strip 15 and can be rearranged independently of each other, with the upper tape 4 showing positive values and the lower 4 negative. Therefore, in each vertical heading, either the positive or negative part must be completely covered by the black half of the tape.

Patent Subject

1. A moving diagram with the use of endless ribbons moved on the main board in the direction of its length, parallel to each other, characterized in that, in order to better shade the data printed on the ribbons (Fig. 1-5), the intervals between the ribbons 4 are overlapped. 9 is placed on top of the ribbons of the lattice 3.

2. In the case of the mobile chart described in paragraph 1, the use of pockets 10, used for placing cards with data with respect to the values shown by the respective ribbons, in which these pockets are closed with a folding lid I.

3. In the case of the mobile diagram described in paragraph 1, the use of marking sticks 13, stuck into the holes 12 made in the upper field of the grid 3.

4. Variation of the mobile diagram described in clause 1, characterized by the use of two groups of endless ribbons (Fig. 6 and 7), between which there is a transverse strip 15 serving as the zero line for the values established by the said groups of ribbons.
