Structure for securing weight plates

摘要

The means for securing weight plates (16) on weight rods (10′, 12) or holder bars provides at least one groove (14) formed in an end region (10′) of a weight rod (10′, 12) or in the holder bar. The weight plates (16) are formed with a radial protrusion (17) in their central bore, preferably extending over only a portion of the circumference. The diameter of the bore at the protrusion (17) is greater than the diameter of the end region (10′) of the weight rod (10′, 12) or holder bar axially next to the groove (14). The protrusion (17) falls into the groove (14) and prevents the weight plate (16) from slipping off the weight rod (10′, 12) or holder bar.

主权项

1. A structure for securing weight plates on a long weight rod, on a dumbbell with a short weight rod or on a holder bar of a piece of exercise equipment or of a rack member, wherein the weight rod on its end regions or the holder bar is provided with at least one circumferentially extending groove, and each weight plate is provided with a bore which on the bore wall has at least one circumferentially extending radial protrusion to be brought into engagement with the groove, and the diameter of the bore at the protrusion is greater than the diameter of the weight rod or of the holder bar axially next to the groove.
