## Abstract

Multiple embodiments of a portable ballet bar exercise device are disclosed.

## Claims

### Claim 1

A portable ballet bar exercise device, comprising:
a single vertical column;
a horizontal bar coupled to a single pivotable neck, the neck coupled to the single vertical column such that the horizontal bar is pivotable about the single vertical column, wherein the single vertical column is adjustable in height and is capable of being locked in place by a locking mechanism;
a cross bar coupled to the single vertical column and spanning a base structure; and
a floor board coupled to the cross bar;
wherein the single vertical column can operate in a first position approximately perpendicular to the base structure, and wherein the single vertical column is foldable about an axis of the cross bar to a second position approximately parallel to the base structure.

### Claim 2 (depends on 1)

The device of claim 1, wherein the base structure comprises rear legs that are extendable from the base structure.

### Claim 3 (depends on 2)

The device of claim 2, wherein the device further comprises a back board.

### Claim 4 (depends on 3)

The device of claim 3, wherein the single pivotable neck comprises at least two pieces.

### Claim 5 (depends on 4)

The device of claim 4, wherein the device further comprises a plurality of wheels.

### Claim 6 (depends on 5)

The device of claim 5, wherein the device further comprises a spring within the single vertical column.

### Claim 7 (depends on 6)

The device of claim 6, wherein the spring is a constant force spring.

### Claim 8 (depends on 7)

The device of claim 7, wherein the back board is constructed from wood.

### Claim 9 (depends on 8)

The device of claim 8, wherein the floor board is constructed from wood.

### Claim 10 (depends on 9)

The device of claim 9, wherein the device further comprises a locking mechanism coupled to the rear legs and the cross bar.

### Claim 11

A portable ballet bar exercise device, comprising:
a horizontal bar coupled to a support mechanism;
a single pivotable neck coupled to the support mechanism;
a single vertical column attached to the neck such that the horizontal bar and support mechanism are pivotable about the single vertical column, wherein the single vertical column is adjustable in height and is capable of being locked in place by a locking mechanism;
a first cross bar coupled to the single vertical column;
a floor board coupled to the first cross bar;
a backboard coupled to the first cross bar;
a base structure coupled to the first cross bar; and
a locking mechanism coupled to the first cross bar and the base structure;
wherein the single vertical column can operate in a first position approximately perpendicular to the base structure, and wherein the single vertical column is foldable about an axis of the first cross bar to a second position approximately parallel to the base structure.

### Claim 12 (depends on 11)

The device of claim 11, wherein the base structure comprises rear legs that are extendable from the base structure.

### Claim 13 (depends on 12)

The device of claim 12, wherein the device further comprises one or more support structures coupled to a second cross bar and the base structure.

### Claim 14 (depends on 13)
