The invention relates to stationery supplies, in particular to containers for storing and transporting items, rolled, first of all sheets of drawings. The invention can be applied in the production of goods of wide application and is used in everyday life and in organizations.

Known case for drawings (tube), containing two popupular (internal and external), one of which is telescopically slide into the other. Profusley mutually fixed due to friction of their cylindrical surfaces (see Tube company "Domingo Ferrer. Spain, the company's Catalog, 1994). Thus, the amount of space to accommodate the rolled object is determined by the length of the roll and may change quickly, smoothly and in a wide range. When transporting the case is suspended on the shoulder using the strap attached to the ends of Polovetsian. The disadvantage of this tube is that it has no rigid fixing of the relative position of Polovetsian. When the great weight of the roll of mutual fixation of Polovetsian becomes unreliable, and the roll may fall out of the tube.

Known tube that contains two popupular, one of which is wrapped around to the other with the historical surface Polovetsian); the tube is suspended from the shoulder by means of a belt, fastened to the ends of Polovetsian(see Case company "ELBA", Germany, Directory, company, 1994 ). Profusley this tube is rigidly fixed relative to each other due to the threaded connection. However, the disadvantage of this tube is the inconvenience of using them, so as to accommodate the roll of a short length need to be wrapped around profusley

Also known tube that contains two popupular cylindrical shape, worn on one another with hard and mutual fixation; the tube is suspended from the shoulder by means of a belt, fastened to the ends of Polovetsian (see case company "KOH-1-NOOP", Czechoslovakia, the company's Catalog, 1994). Fixing the mutual position of Polovetsian provided in several positions in accordance with standard length rolls of drawings (under the format of A1, A2, A3, A4). Fixation was performed using Zamanov, located perpendicular to the generatrix of the cylindrical surface, made in one polyfuse, and rusty, also located perpendicular to the generatrix of the cylindrical surface, is made in another polyfuse. When the lower internal propular in the outer in positions corresponding to the sizes of formats Batut on the deformation zones of the surface of propular in locations rusty. The design of this tube allows you to quickly change the size of the storage space of rolled items at fixed formats of sheets of paper. However, the disadvantage of this tube is that it is not enough to fix the mutual position of Polovetsian. When the great weight of the roll of mutual fixation of Polovetsian becomes unreliable, and the roll may fall out of the tube. As the closest analogue to the invention, the selected known case containing a receptacle for rolled object formed from the halves, connected with the possibility of telescopic extension of one another and tied one to another inside through progestagenic elastic cords with strain together with the nomination of one of the halves and snagging one of the halves over the edge of the other by means of a ring worn on the outside to put forward half with the possibility of fixing it in any place (see Case, SU, and. C. N 1416102, class A 45 C 11/24, 1988). The disadvantages of this case (tube) are insufficient manufacturability (many operations to manufacture), inconvenience of use - you have to adjust the size of the space to accommodate the roll.

The technical result is achieved by the fact that, as in the nearest analogue, case for drawings contains internal popupular, telescopically udegey in the outer popupular to lock the relative position of the inner popupular relative to the outer popupular a few fixed positions with the clamp position, the latter is in the form of embossed surfaces wetted parts internal popupular and outer propular in places fixing their relative position. Unlike closest retainers provisions made in the form of two tabs, radius passing from one to the other with one hand and mud on themselves with the other hand on one polyfuse and in the form of protrusions on the other polyfuse. These protrusions is oriented perpendicularly to the forming cylindrical surfaces of Polovetsian.

Profusley are cylindrical in shape and slide into one another with discrete fixing their relative position, for example, appropriate placement in the tube sheets of standard paper formats. Fixing the desired mutual position (under the required size of the roll of the subject) is the connection of parts to fix the your of this solution is that it allows you to store and transport a greater number of rolled items at a constant firmly Polovetsian. In comparison with analogues such tube simpler and more adaptable to production. For example, for the prototype required the construction of classes of accuracy from the third to the fifth, then how to make the proposed device according to the seventh accuracy class.

The device contains an internal popupular 1 and the outer popupular 2 (see Fig. 1), which telescopically slide into one another (see Fig. 1 and Fig. 2). On the inner polyfuse 1 made ribs 3 in the form of two oriented perpendicular to the generatrix of the cylindrical surface protrusions, radius passing one another on the one hand and mud on themselves - on the other (see Fig. 6 and Fig. 7). On the outer polyfuse 2 has grooves 4 (on the inner side of the outer popupular 2 - tabs, see Fig. 9 and Fig. 10), oriented perpendicular to the generatrix of the cylindrical surface of the outer polluter 2 and mud on both sides for yourself. The size of riffles 3 and grooves 4 are selected so that the inner popupular 1 and the outer popupular 2 freely diglis were put forward (see Fig. 8 and Fig. 10). The coincidence riffles 3 and grooves 4 by the rotation of the internal popupular 1 relative to the outer popupular 2 is achieved by fixing their relative position (groove 4 is included in the corrugation 3, see Fig. 3).

The tube used in the following way. Open the tube (fully nominated internal popupular 1 from the outdoor popupular 2), internal popupular put 1 roll of redemption, 3 and grooves 4, mutually rotate the inner popupular 1 and the outer popupular 2 up to the stop grooves 4 in the cylinders 3. Then the tube with a rolled item is ready for storage and transportation.

The case for drawings containing internal popupular, telescopically udegey in the outer popupular to lock the relative position of the inner popupular relative to the outer popupular a few fixed positions using clamps provisions made in the form of embossed surfaces wetted parts internal popupular and outer propular in places fixing their relative position, wherein the tabs of the provisions made in the form of two tabs, radius passing from one to the other with one hand and mud on themselves with the other hand on one polyfuse, and in the form of protrusions on the other polyfuse, while the tabs are oriented perpendicular to the forming cylindrical surfaces of Polovetsian.
