ABSTRACT:
A striking apparatus includes a resilient joint between a support and a strike receiving target. The hinge member has two resilient leaves joined to each other and retaining the target therebetween. A set of central stiffeners on the hinge leaves defines the preferential hinge axis. The apparatus includes a base section with a support arm which is attachable through a bracket to a vertical support. Posts extending perpendicular to planar plates defining the support and the target carry changeable dampers in the form of bands, O-rings or flexible rods, for user selection of target resistance.
