Abstract: An improvement to a striking bag for boxing or martial arts practice, which provides aural feedback to the user, as to the accuracy of strikes. Compressible pneumatic targets (10-A, 10-B, 10-C) are mounted partially into the side of a striking bag (9). Targets (10-A,10-B,10-C) are compressible both outside and inside the surface of the striking bag (9). When any of the pneumatic targets (10-A, 10-B, 10-C) are compressed by a strike, displaced air is driven into a pneumatic hose (34, 36, 38 respectively) which runs through the interior of the striking bag, connecting the pneumatic target to a whistle (12). Flexible washers on the inside (14) and outside (16) of striking bag (9) mount each pneumatic target (such as 10-A), onto striking bag (9). The inner washer (14), and outer washer (16), are connected through the surface of striking bag (9) by bolts (18,20,26, 28) and nuts (22,24,30,32). Alternate embodiments include pneumatic targets (10-D,10-E,10-F, 10-G,10-H).

Abstract: A retractable key holder having an external housing and an internal housing pivotably secured at least partially within the external housing by pivot pins, a retractable transverse spring biased pin that extends through substantially vertically aligned slots formed in the external and internal housing, an actuator button on each end of the retractable pin and positioned outside the external housing for access by a user, and a key ring attached to the spring biased pin. The user can retract keys secured on the key ring into the internal housing by retracting the retractable pin along the length of the slots and pivot the internal housing within external housing until the keys engage a sound buffering material within the external housing disposed to press against keys to prevent rattling of the retracted keys.
