## Abstract

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.

## Claims

### Claim 1

A weight apparatus, comprising:
a bar comprising
a handle,
an anchorage rotatably mounted to an end of the handle, the handle and the anchorage having an axially extending opening,
a first rod slidably disposed inside the axially extending opening,
a second rod slidably disposed inside the axially extending opening,
the first rod and the second rod being movable between a retracted position in which the first rod and the second rod overlap a first length and an extended position in which the first rod and the second rod do not overlap, and
wherein the first rod and the second rod are movable in opposite directions upon rotation of the handle relative to the anchorage.

### Claim 2 (depends on 1)

The weight apparatus as set forth in claim 1, wherein the handle comprises a first and a second end, and the bar comprises a first and a second anchorage on the first and the second end of the handle, respectively.

### Claim 3 (depends on 2)

The weight apparatus as set forth in claim 2, wherein the first and the second anchorage are substantially identical.

### Claim 4 (depends on 1)

The weight apparatus as set forth in claim 1, wherein the handle extends into the anchorage and is mechanically linked to the first rod.

### Claim 5 (depends on 1)

The weight apparatus as set forth in claim 1, comprising a member disposed between the first rod and the second rod.

### Claim 6 (depends on 1)

The weight apparatus as set forth in claim 1, comprising a weight, the weight and the anchorage comprising a joint that permits radial movement of and prevents axial movement of the second weight relative to the anchorage.

### Claim 7 (depends on 6)

The weight apparatus as set forth in claim 6, wherein the weight comprises an axial opening, and the rod is adapted to be axially moved into and removed from the axial opening, the weight being prevented from axially moving relative to the anchorage body when the rod is disposed in the axial opening of the weight.

### Claim 8 (depends on 6)

The weight apparatus as set forth in claim 6, comprising at least one second weight, the weight and the second weight comprising a joint that permits radial movement and prevents axial movement of the second weight relative to the weight or another second weight.

### Claim 9 (depends on 8)

The weight apparatus as set forth in claim 8, wherein the weight comprises a weight axial opening and the at least one second weight comprises a second weight axial opening, and the rod is adapted to be axially moved into and removed from the weight axial opening and the second weight axial opening, the weight and the second weight being prevented from axially moving relative to the anchorage body when the rod is disposed in the weight axial opening and the second weight axial opening.

### Claim 10 (depends on 1)

The weight apparatus as set forth in claim 1, comprising at least one radially extending pin, the radially extending pin being movable relative to the anchorage between an innermost position in which an outer end of the pin is disposed radially inside or even with an external surface of the anchorage and an outermost position in which the outer end of the pin extends radially beyond the external surface of the anchorage, and
an auxiliary weight comprising a weight opening in which the anchorage is adapted to be received, the weight comprising a radially extending pin opening adapted to receive the outer end of the pin when the pin is in the outermost position to attach the weight to the anchorage.

### Claim 11 (depends on 10)

The weight apparatus as set forth in claim 10, wherein the handle comprises a cam surface having a first portion with a first diameter and a second portion with a second diameter smaller than the first diameter, the first diameter of the first portion of the cam surface being such that the first portion of the cam surface contacts the inner end of the pin so that the pin is not movable inwardly of the outermost position when the handle is rotated to a first position relative to the anchorage, and, the second diameter of the second portion being such that, when the handle is rotated to a second position relative to the anchorage, the inner end of the pin is adapted to contact the second portion of the cam surface so that the pin is movable to the innermost position.
