## Abstract

One embodiment of a support assembly comprises an elongated rail, a support sleeve slidable along the elongated rail, a handle attached to the support sleeve and having a central axis, a first grip and a second grip on opposite sides of the central axis and each grip being connected to the other by first and second connecting members that combine with the first and second grips to form a handle frame.

## Claims

### Claim 1

A support assembly comprising:
an elongated rail;
a support sleeve slidable along the elongated rail;
a handle adjustably attached to the support sleeve and having a central axis, a first grip and a second grip positioned on opposite sides of the central axis;
each grip being connected to the other by first and second connecting members that combine with the first and second grips to form a handle frame.

### Claim 2 (depends on 1)

The support assembly of claim 1, wherein the support sleeve slides only under a force substantially along the elongated rail.

### Claim 3 (depends on 2)

The support assembly of claim 2, wherein the support sleeve slides in only one direction at a time along the elongated rail based on a user selection.

### Claim 4 (depends on 3)

The support assembly of claim 3, further comprising a friction wheel for controlling the direction of travel of the support sleeve.

### Claim 5 (depends on 1)

The support assembly of claim 1, wherein the support sleeve limits the rate of movement along the elongated rail.

### Claim 6 (depends on 1)

The support assembly of claim 1, wherein the handle frame is rotatable about the central axis.

### Claim 7 (depends on 6)

The support assembly of claim 6, further comprising a locking mechanism for fixing the orientation of the handle frame about the central axis.

### Claim 8 (depends on 1)

The support assembly of claim 1, wherein the handle frame is substantially rectangular.

### Claim 9 (depends on 1)

The support assembly of claim 1, wherein the first grip and the second grip are arched towards the central axis.

### Claim 10 (depends on 8)

The support assembly of claim 8, wherein additional gripping elements are located at each corner of the handle frame.

### Claim 11 (depends on 1)

The support assembly of claim 1, further comprising a bisector connecting the first connecting member to the second connecting member that bisects the handle frame along the central axis.

### Claim 12 (depends on 11)

The support assembly of claim 11, further comprising an additional support feature attached to the handle.

### Claim 13 (depends on 12)

The support assembly of claim 12, further comprising one or more of a tray, a hook or a magazine rack attached to the bisector.

### Claim 14 (depends on 12)

The support assembly of claim 12, wherein the bisector extends beyond the second connecting member and forms a hook.

### Claim 15 (depends on 1)

The support assembly of claim 1, further comprising an additional support feature attached to the handle.

### Claim 16 (depends on 15)

The support assembly of claim 15, further comprising one or more of a tray, a hook or a magazine rack attached to the handle.

### Claim 17 (depends on 1)

The support assembly of claim 1, wherein the first connecting member and the second connecting member are extendable to vary the distance between the central axis and each of the grips.

### Claim 18 (depends on 17)

The support assembly of claim 17, wherein the distance between each of the grips and the central axis can be varied independently of each other.

### Claim 19 (depends on 1)

The support assembly of claim 1, wherein the connecting members extend telescopically.
