An improved striking device is provided as including a main post having two main longitudinal slots. An insert post having an outside diameter that is less than the inside diameter of the main post is provided. A striking surface is provided that is attached to an arm which in turn is attached to an arm housing. The arm housing has a first housing end and a second housing end. The arm housing is placed around the main post and the second housing end rests upon a support axle passing through the insert post. The first housing end includes a cam surface having two peaks located on opposite sides thereof and two valleys located on opposite sides thereof with each of the two valleys disposed between each of the two peaks. A cam follower is included which is retained in contact against the cam surface by a pair of springs. During rotation of the arm housing the cam follower cooperates with the cam surface of the arm housing to provide a first striking position and a second striking position that are each located one hundred and eighty degrees of rotation apart with respect to each other. As the arm housing rotates the cam surface extends the cam follower which is turn extends the pair of springs in proportion to the contour of the cam surface. If sufficient force is imparted to the striking surface, the arm housing is urged away from the first striking position, and indexes into the second striking position.

A striking device useful for training, comprising: (a) base means; (b) main post means attached at one end thereof to said base means and extending generally in an upward direction therefrom; (c) insert post means adapted for insertion in said main post means, said insert post means able to be disposed within said main post means along a longitudinal axis thereof; (d) means to secure said insert post means where desired along said longitudinal axis; (e) arm housing means adapted to fit over said main post means, said arm housing means having cam surface means attached at a first housing end and having bearing surface means at a second housing end thereof; (f) said cam surface means having two peaks and two valleys with each of said two peaks being disposed at opposite sides of said first housing end and each of said two valleys being disposed between each of said two peaks and at opposite sides thereof; (g) arm means attached to said arm housing means and extending a predetermined distance therefrom; (h) striking surface means attached to said arm means at an end of said arm means opposite to where said arm means is attached to said arm housing means; (i) cam follower means having a first cam follower means end and a second cam follower means end, said cam follower means including means to maintain cooperation of said cam follower means with said insert post means wherein said means to maintain cooperation of said cam follower means with said insert post means includes bearing means attached to said cam follower means and said insert post means includes insert post slot means, said insert post slot means being adapted for cooperation with said bearing means; (j) spring means attachable to said insert post means at one end of said spring means and attached to said cam follower means at the remaining end of said spring means, said spring means applying a force sufficient to maintain said cam follower means in a position of cooperation with said cam surface means and to cause said cam follower means to apply a force sufficient to rotate said arm housing means to a first striking position wherein said first cam follower means end is disposed substantially in a position of cooperation with one of said two valleys and said second cam follower means end is disposed substantially in a position of cooperation with a remainder of said two valleys; and (k) support axle means passing through a pair of holes provided in said insert post means, said support axle means providing means for maintaining said arm housing means in a relative position of cooperation with respect to said insert post means; whereby when said striking surface means is struck by a force that is insufficient to rotate said arm means in excess of ninety degrees with respect to said main post means, said cam follower means is able to apply a force to said cam surface means sufficient to rotate said arm housing means back to said first striking position, and when said striking surface means is struck by a force that is sufficient to rotate said arm means in excess of ninety degrees with respect to sad main post means, said cam follower means is able to apply a force to said cam surface means sufficient to rotate said arm housing means to a second striking position wherein said first cam follower means end is disposed substantially in a position of cooperation with said remainder of said two valleys and said second cam follower means end is disposed substantially in a position of cooperating with said one of said two valleys, and said arm housing means is maintained in the same position with respect to said longitudinal length of said main post means when said arm means is rotated from said first striking position to said second striking position.
