The invention relates to entertainment industry, in particular to means for body throwing. Catapult is taken by handle with hand of one arm (for instance, the left one), under protection panel, at that the support rests on forearm, and surrounding part surrounds it. To the right hand one takes holding section of leather element, one installs leather element to holder on guide section, brings to magazine with charging one of missiles to leather element. After that, at holding in right hand the holding part, one tightens missile bunch with direction catapult to site of target, with visual fixation of light point from laser light source at the last one. With thumb of right hand through lever, con-rod, wedge one turns the holder on the axis with release of the leather element. The last one together with the missile under effect of kinetic energy stored by missile bunch moves along trajectory coinciding with working plane (K-K) of missile bunch till coming to possible end position that is determined by length of missile bunch. After that the missile moves to the side of the target itself and the leather element – to the opposite side, at that the left hand is protected against injury with protective screen. At release of the lever the wedge is taken out from guide under effect of the spring and holder under effect of pressing ring is turned to initial position and is ready for installation of leather element and next missile there. Depending on range of shooting expected correction can be included, this is carried out by means of change of height of installation of sight slat with respect to guide section. Possibility of connection of direction of missile flight and direction of laser beam from source is claimed, with decrease of bending loads ion hand in area of hand joint, with provision of convenience and reliability of holding leather element with hand, this makes it possible to give large kinetic energy to missile. |
