Weight apparatus including weight adjustment arrangement
A weight apparatus includes a handle, first and second anchorages mounted to first and second ends of the handle, respectively, the handle and the first and second anchorages having an axially extending opening, first and second rods axially movable inside the axially extending opening and adapted to be moved axially relative to the axially extending opening in opposite directions upon rotation of first and second pinion gears in the first and second anchorages, respectively, that engage with first and second racks on the first and second rods, respectively, and a lock having a locked condition in which rotation of the first and second pinion gears is prevented and an unlocked condition in which rotation of the first and second pinion gears is permitted.
1. A weight apparatus, comprising:
a handle,
first and second anchorages mounted to first and second ends of the handle, respectively, the handle and the first and second anchorages having an axially extending opening,
first and second rods axially movable inside the axially extending opening and adapted to be moved axially relative to the axially extending opening in opposite directions upon rotation of first and second pinion gears in the first and second anchorages, respectively, that engage with first and second racks on the first and second rods, respectively,
a lock having a locked condition in which rotation of the first and second pinion gears is prevented and an unlocked condition in which rotation of the first and second pinion gears is permitted.
2. The weight apparatus as set forth in claim 1 , wherein the first and the second anchorages are substantially identical.
3. The weight apparatus as set forth in claim 1 , wherein the first and second pinion gears are non-rotatably mounted on first and second axles disposed in the first and second anchorages, respectively.
4. The weight apparatus as set forth in claim 2 , wherein the first and second pinion gears are rotatably mounted in first and second pinion housings disposed in the first and second anchorages, respectively, the first and second axles extending through openings in the first and second pinion housings, respectively.
5. The weight apparatus as set forth in claim 4 , comprising a tube extending through the axially extending opening from the first anchorage to the second anchorage, the first and second pinion housings and the first and second pinion gears being disposed inside of the tube at first and second ends of the tube, respectively.
6. The weight apparatus as set forth in claim 5 , wherein the first and second axles extend through openings in the first and second ends of the tube, respectively.
