Sports shooting target and corresponding launching device and apparatuses
The invention relates to a sports shooting target made of a biodegradable material, the target having a rotational axis (z) and attachment means ( 2, 4′, 4″, 10, 11, 15 ) for releasable attachment to a launching device, where the target is provided with trajectory stabilizing means that are configured to stabilize the trajectory of the target by gyro effect caused by rotation about said rotational axis (z) which stabilizing means further function as propelling means that cause forward movement of the target along its trajectory due to the rotation about said rotational axis (z), when the target is rotating, where said stabilizing means comprises a fan comprising fan blades ( 3′, 3″ ) that rotates in unison with the target, when the target rotates, such that the stabilizing means both provides said stabilizing gyro effect and forward propulsion (movement) of the target along a chosen trajectory. The target comprises a hub portion ( 2, 15 ) configured for releasable attachment to a corresponding portion of a launching device and a plurality of concentric ring members ( 5, 6, 7; 12, 13, 14 ) arranged about the rotational axis (z) of the target at different distances (r 5 , r 6 , r 7 ) from the rotational axis (z) and outside the hub portion ( 2 ) The stabilizing means comprises first fan blades ( 3 ′) that extend radially from the hub portion ( 2, 15 ) to the ring member ( 7, 14 ) provided at the largest distance from the rotational axis (z) and second fan blades ( 3 ″) that extend radially between two adjacent ring members. The invention further relates to a launching device for launching the target, launching apparatuses comprising the launching device of the invention as well as a method of launching targets for skeet shooting and similar sport shooting activities.
1. A sports shooting target made of a biodegradable material, the target having a rotational axis (z) and attachment means configured for releasable attachment of the target to a launching head of a launching device, wherein the target is provided with trajectory stabilizing means that are configured to stabilize the trajectory of the target by gyro effect caused by rotation about said rotational axis (z) which stabilizing means further function as propelling means that cause forward movement of the target along its trajectory due to the rotation about said rotational axis (z), when the target is rotating, wherein said stabilizing means comprises a fan comprising fan blades that rotates in unison with the target, when the target rotates, such that the stabilizing means both provides said stabilizing gyro effect and forward propulsion (movement) of the target along a chosen trajectory wherein:
the sports shooting target comprises a hub portion configured for releasable attachment to a corresponding portion of a launching head of a launching device; and
the hub portion is provided with an inner circumferential surface facilitating release of the target from said portion of the launching head and defining an inner space;
the target comprises a plurality of concentric ring members arranged about the rotational axis (z) of the target at different distances from the rotational axis (z) and outside the hub portion;
the stabilizing means comprises first fan blades that extend radially from the hub portion to the ring member provided at the largest distance from the rotational axis (z); and
wherein the hub portion further comprises inwardly sloping surfaces that converge towards the longitudinal rotational axis (z) of the target, wherein the sloping surfaces have similar slope angles relative to the longitudinal axis (z), whereby the hub portion of the target is attachable to the launching head from either side of the target.
2. A sports shooting target according to claim 1 , wherein said ring members have cross-sectional shapes comprising curved first and second side faces, wherein the first and second side faces meet at a substantially sharp edge portion, thereby optimizing the aero-dynamic properties of the respective ring members.
3. A sports shooting target according to claim 1 , wherein said second fan blades are provided between the outermost ring member and the adjacent ring member.
4. A sports shooting target according to claim 1 , wherein the inclination angle of the fan blades relative to an (x, y) plane of the target increases towards the hub portion.
5. A sports shooting target according to claim 1 , wherein said inner circumferential surface of the hub portion is conical.
6. A sports shooting target according to claim 1 , wherein the plurality of concentric ring members comprises an innermost ring member located closest to the hub portion, a middle ring member and an outermost ring member located furthest from the hub portion, the second fan blades extending radially only between the middle ring member and the outermost ring member.
