ABSTRACT:
A resistance weight kit which may be readily installed in a door frame. The resistance weight kit includes an extendable screw threaded support bar assembly (22) having rubber feet (28) at either end which may engage the sides of a door frame in an elevated position. Mounted on the support bar assembly are two radiallly outwardly extending eyes (52). A first pulley block (14) may be secured to one of the eyes (52) by a quick connector (60). A second pulley block (16) is provided and intermediate portions (74, 76) of a primary rope (18) engage the sheaves (58) of each of the pulley blocks. The ends of the rope are formed into eyes and one end (80) may be connected to the other radially outwardly extending eye (52) by another quick connector (60). A weight holder (12) is connected to an eye (56) on the second pulley block (16) by another quick connector (60). An engagement device is connected to the eye (78 ) on the other end of the rope by another quick connector (60). The engagement device may be a baseball (88) with an extension length of rope (86). Alternatively, it may be a cross bar (110) or ankle band (122). The kit may further include a platform (20) having a third pulley block (114) mounted thereon, another extension length of rope (116) passing through the pulley block and having eyes at either end, the platform mounted extension length of rope also being quickly connectable.
The kit may be used for physical therapy and rehabilitation after injury or surgery, and also for physical training, such as for example in instructiong a baseball player in the proper overhand throwing technique.
