## Abstract

A mechanical arm assembly which has two arm members connected by an elbow. The movable connectors at the end of each arm are connected by belts or the like to a locking mechanism at the elbow such that engaging the locking mechanism simultaneously locks both movable connectors as well as the elbow.

## Claims

### Claim 1

A mechanical arm comprising:
a) A first and second arm,
b) A first and a second positionable connector mechanism, said first positionable connector secured to a second end of the first arm, said second positionable connector secured to a second end of the second arm, said first positionable connector being selectively positionable relative to the first arm, and the second positionable connector being selectively positionable relative to the second arm;
c) An elbow mechanism secured to a first end of the first arm and a first end of the second arm, said elbow mechanism allowing relative movement between the first and second arms;
d) A first belt extending between the elbow mechanism and the first positionable connector such that movement of the first positionable connector causes movement of the first belt;
e) A second belt extending between the elbow mechanism and the second positionable connector such that movement of the second positionable connector causes movement of the second belt;
f) A manually operated locking mechanism located at the elbow, said manually operated locking mechanism simultaneously engaging the first belt and the second belt such that said locking mechanism is able to simultaneously prevent the first belt and the second belt from movement and the elbow mechanism.

### Claim 2 (depends on 1)

The mechanical arm according to claim 1, further including,
a) A first sprocket engaging the first positionable connector;
b) A second sprocket engaging the second positionable connector;
c) A third sprocket engaging the manually operated locking mechanism; and,
d) Wherein the first belt extends around the first sprocket and the third sprocket; and,
e) Wherein the second belt extends around the second sprocket and third sprocket.

### Claim 3 (depends on 2)

the mechanical arm according to claim 2, wherein the first belt and the second belt each contain teeth adapted to engage the sprockets.

### Claim 4 (depends on 2)

The mechanical arm according to claim 2, further including a mounting mechanism secured to a surface; and, wherein the second positionable connector is securable to the mounting mechanism.

### Claim 5 (depends on 4)

The mechanical arm according to claim 4, further including a track; and, wherein the mounting mechanism is secure to the track.

### Claim 6 (depends on 3)

The mechanical arm according to claim 3, wherein the track is secured to a ceiling.

### Claim 7 (depends on 1)

The mechanical arm according to claim 1, further including an attachment mount and wherein the first positionable connector is securable to the attachment mount.

### Claim 8 (depends on 7)

The mechanical arm according to claim 7, wherein the attachment mount is secured to a monitor.

### Claim 9

A mechanical arm comprising:
a) A first and second arm connected at their proximal ends via an elbow, said elbow having a manually operated locking mechanism;
b) A first and a second positionable connector mechanism connected to the distal ends of the first and second arms respectively;
c) A first belt extending between the locking mechanism and the first positionable connector and a second belt extending between the locking mechanism and the second positionable connector; and,
d) Wherein engagement of the locking mechanism simultaneously locks the first belt and the second belt to simultaneously prevent the first belt and the second belt from movement as well as the elbow mechanism.

### Claim 10 (depends on 9)

The mechanical arm according to claim 9, further including,
a) A first sprocket engaging the first positionable connector;
b) A second sprocket engaging the second positionable connector;
c) A third sprocket engaging the manually operated locking mechanism; and,
d) Wherein the first belt extends around the first sprocket and the third sprocket; and,
e) Wherein the second belt extends around the second sprocket and third sprocket.

### Claim 11 (depends on 10)

the mechanical arm according to claim 10, wherein the first belt and the second belt each contain teeth adapted to engage the sprockets.

### Claim 12 (depends on 11)

The mechanical arm according to claim 11, wherein the first belt and the second belt are made of flexible material.

### Claim 13 (depends on 11)

The mechanical arm according to claim 11 wherein the first belt and the second belt are metal.

### Claim 14

A mechanical arm comprising:
a) A first and second arm connected by an elbow at a proximal end, each arm having a connector at a distal end thereof;
b) A first belt extending between the elbow mechanism and the connector of the first arm such that movement of the t connector of the first arm causes movement of the first belt;
c) A second belt extending between the elbow mechanism and the connector of the second arm such that movement of the connector of the second arm causes movement of the second belt; and,
d) A manually operated locking mechanism located at the elbow, said manually operated locking mechanism simultaneously engaging the first belt and the second belt adapted to lock the first belt and the second belt in a stationary position.

### Claim 15 (depends on 14)

The mechanical arm according to claim 14, further including,
a) a first sprocket engaging the positionable connector of the first arm;
b) A second sprocket engaging the positionable connector of the second arm;
c) A third sprocket engaging the manually operated locking mechanism; and, d) wherein the first belt extends around the first sprocket and the third sprocket; and, e) wherein the second belt extends around the second sprocket and third sprocket.

### Claim 16 (depends on 15)

the mechanical arm according to claim 15, wherein the first belt and the second belt each contain teeth adapted to engage the sprockets.

### Claim 17 (depends on 16)

The mechanical arm according to claim 16, wherein the first belt and the second belt are made of flexible material.

### Claim 18 (depends on 16)

The mechanical arm according to claim 16 wherein the first belt and the second belt are metal chains. n
