The disk consists of a base 1 with a protrusion 3 and a figured tucker 5 and a profile washer 2. The base and the washer are fixed to each other with a screw 6 with a conical head. Between the base and the washer there is a variable cross-section cavity 9. In it is placed a replaceable cargo package 10 - 12. These weights are made in the form of concentric rings, forming a cross-sectional collection form corresponding to the shape of the cavity. In particular, this form is made conical. Cargo can be placed in the cavity together or separately. In the latter case, projections 13 are provided in the base 1 for fixing the average load 11.

В шайбе 2 выполнено коническое отверстие дл размещени допол-пп ннтельной шайбы 8 и конической головки винта. Между основанием и шайбой 2 образована полость 9 переменного сечени дл размещени сменного пакета грузов, выполненных в виде кон- 25 центричных колец 10 - 12. Пакет грузов в сборе имеет форму в поперечном сечении, соответствующую форме полости корпуса. В частности, эта форма представл ет собой вид обращенных большими основани ми один к друго- му двух усеченных конусов. В основании выполнены выступы 13, а в среднем кольце 11 - ответные им отверсти дл фиксации кольца.with a hole 6 and a figured recess 5. Parts of the body assembly are fixed between each other by a screw 6 with a conical head 7. A washer 2 is made in the washer 2 to accommodate the add-on washer 8 and the conical screw head. A variable section cavity 9 is formed between the base and the washer 2 to accommodate a replaceable cargo package made in the form of concentric rings 10-12. The assembly cargo package has a cross-sectional shape corresponding to the shape of the housing cavity. In particular, this form is a form of two truncated cones facing one large another. At the base, protrusions 13 are made, and in the middle ring 11, there are holes corresponding to them for fixing the rings.

Выступ 3 основани и бокова поверхность 14 выточки 5 могут иметь скосы дл исключени проворота колец. Масса колец может быть выполнена с различным соотношением либо 1:1:1, либо 1:2:4. В последнем случае обеспечиваетс возможность максимального количества вариантов сборки снар да при минимальной градации изменени . массы грузов.. При этом максимальной массой должен обладать груз 10.The protrusion 3 of the base and the side surface 14 of the undercut 5 may be bevelled to prevent the rings from turning. The mass of the rings can be performed with a different ratio of either 1: 1: 1 or 1: 2: 4. In the latter case, it is possible to maximize the number of projectile assembly options with minimal gradation of change. mass of cargo .. In this case, the maximum mass should have a load of 10.

При этом грузы можно установить все (как показано на фиг. 1) или в различном сочетании, или по одному . При этом от перемещени грузы удерживаютс : при установке одного груза 10 коническими поверхност ми 5 и 9 и выступом 3, груза 11 - выступами 13 основани , а груза 12 - боко40If necessary, change the weight of the projectile and unscrew the screw 6, remove the washers 8 and 2, opening access to the cargo 10-12. In this case, the cargo can be installed all (as shown in Fig. 1) or in various combinations, or one by one. At the same time, the loads are prevented from moving: when installing one load 10 with conical surfaces 5 and 9 and a projection 3, the load 11 - with the projections 13 of the base, and the load 12 - laterally 40

Claims

1. A throwing disk containing a composite housing of two parts with an alternating cross section cavity between them and axial holes, one of which is made conical and the other threaded to accommodate means for fixing body parts and a package of interchangeable weights that differ By the fact that, in order to increase the usability while using the centering, the package of replaceable weights is placed in the housing cavity and consists of concentric rings, the shape of which in the cross section assembly corresponds to the shape of the cavity, while discharge of the housing parts provided with protrusions, and the average of the rings - openings for its fic sation to them.

2. The disk of claim 1, which distinguishes the fact that the shape of the cavity of the couspus and the cross section of the assemblies of the rings is a cone that face large bases facing each other.

3.Disc on tt. 1 and 2, which is based on the fact that one part of the body is made in the form of a base with an axial protrusion, with a central threaded hole in it to accommodate a screw with a conical PF and figures

bitten out the surfaces of the notches 5. The parts of the projectile are fixed in reverse order.

If interchangeable weights have an equal weight, then with a change in weight of 0.5 kg, a change in the mass of the disk can be made within 1.5 kg, and when carrying out loads with a mass ratio of 1: 2: 4 or 2: 1: 4 when changing grades of mass of 0.25 kg achieve a change in the mass of the disk within 1.75 kg.
