Abstract

The invention relates to drawing equipment and is intended to fasten drawing sheets of different, personal formats. The purpose of the invention is to improve ease of operation. Stretched elastic bands are bent through the edges of the panel. The ribbons are fastened to the ends by means of sliders. The guides are made at the panel along the upper and lower edges thereof. The slides are mounted on the guides movably with the possibility of fixation. Tapes have levers suspended to them on the slider. The levers are hingedly connected with the sliders and have a handle on one shoulder, while the other shoulder is connected under the tapes so that the tapes can be pulled out from the front side of the panel. The ends of the belts are attached to the sliders through the couplings. The couplings of one of the halves screwed together are connected with sliders, and the other with tapes. 1 Cp. Fg-ly, 2 ill.

The invention relates to drawing-on when attaching a drawing sheet to any equipment and is intended for someone else to format tape 2, fix mounting drawing sheets, drawings, roll along the edges of the drawing sheet so schemes, posters and other media are placed under them. At the same time, the formations of various formats are applied to the drawing — press the handle of the levers 7 with each demonstration or advertising tape 2, pulling it away from the panel 1, the board, and move each tape 2 to the half. the desired position of the Cr - in at work. The Q drawing sheet is inserted under the ribbon 2. In Figure 1, the drawing sheet is shown and then the knob levers are released. ka, general view; 2 - section 2 of the Ribbon due to the elastic elasticity A-A in FIG. Tension of the tapes 2

The drawing board contains panel 1, rute, screwed halves. 8 and 9 couplings,

through the opposite edges of which, if necessary, the sliders 6 are set, stretched, stretched two elastic sheets, either on the edge of the drawing sheet,

tape 2. The latter fit snugly 20 or behind its edge, to panel 1 from the front and end

Claims (2)

They are attached by means of sliders 3 of the invention to guides 4 and 5, which are extended along the upper and lower edges of the drawing board, containing  Panel 1 from the side of her. The fully stretched elastic tapes, the over-sleeves 3 are mounted movably onto the pipes through the opposite edges of the pan-guides 4 and 5 with the possibility of a fixture and tightly adjacent to it with faceting on them. Tapes 2 have a proxy side, differing from 6 levers 7. on them, which, for the purpose of increasing convenience The sliders 6 are movably mounted at 30 in work, the tape ends are attached ribbons 2 with the ability to move by means of sliders to the guides, by him. The levers 7 are hingedly connected at the panel from the edges with all of the sliders 6 and have, on one shoulder, movement together with the handle, and the other shoulder is brought by slider mounted movably with under the tape 2 flat surface with. 35 by the possibility of fixing on the rounded edges. Articulated connections have Levers 7 with 6-slider 6 slider slides movably mounted on complete by means of an axis with optional tapes Stew squeeze tapes raised by levers, pivotally connected to these levers 7 from the front 40polzushkami and summed under the tape panels 1. with the possibility of pressing tapes from the front side of the panel. The ends of the strips 2 are attached to the creeper. 2. The drawing board according to item i, we are 3 through couplings, which consist in the fact that the ends 8 halves screwed together are attached to the sliders through and 9. One half 8 of each clutch, which is one of the screwed connected to the slider, and the other between the halves, connected to tape 2, sliders and another with tape .. J FIG. 2
