Abstract: A support for a manikin is provided having a pair of opposed elongated extension members having a continuous substantially smooth outer surface forming a cradling surface to support a manikin minimizing the possibility that movement of the manikin will be interfered with through contact with the members when the manikin is removed from the cradling surface.

Abstract: A support for a manikin is provided having a pair of opposed upstanding extension members forming a cradling surface to support a manikin. One of the extension members is biased in an inward direction toward the second extension member to return to a normal position and moveable from the normal position in an outward direction away from the other extension member upon application of a pre-determined force on the extension member.

Abstract: A joint for rotatably connecting a distal part to a proximal part of a testing and training target the joint including a first member attachable to one of the distal part and the proximal part of the target, a second member attachable to the other of the distal part and the proximal part of the target with the first and second members being rotatable relative to each other and engageable with each other such that the first member may be rotated with respect to the second member between first and second positions and upon the application of a predetermined force rotated past the second position to a third position. A detent communicates with one or both of the first and second members preventing movement of the members past the second position to the third position until at least the first predetermined force is applied to one or both of the members.

Abstract: A joint for releasably and pivotally connecting a mannequin to a support structure as might be used, for example in simulating martial arts skills such as those associated with judo, wrestling, jujitsu, akido, karate, taekwon do, etc. and other body contact sports including football, rugby and the like and in related testing, training and rehabilitative programs. The support structure includes a pivot member connected to the mannequin having a semispherical shaped pivot contact surface and an annular ring connected to the support having an annular ring contact surface for receiving the pivot member which permits circumductal rotation of the pivot member in the ring. A connector connects the pivot member to a resisting force which acts to constrain the pivot member within the ring against the ring contact surface and to permit pivotal movement of the pivot member within the ring against the force of the resisting force.
