## Abstract

An extension arm connected to a panel of a safety sign is moveable between a first position extending laterally of the panel a distance at least equal to the maximum width of the panel and a second position. In one embodiment the arm is an assembly held to a handhold of the safety sign. In some embodiments the arm is hinged for folding in the manner of a carpenter's rule. In some embodiments the arm is rotatable between an operative laterally extending, generally horizontal, position and a stowed position. In other embodiments, an A-frame safety sign has a removable arm attached to it, the removable arm when attached being movable to a position extending outward a distance at least equal to the maximum width of the panel.

## Claims

### Claim 1

In combination, an A-frame safety sign having a first panel and a second panel hinged together at an upper portion of each panel by two spaced apart hinges and a handhold between the hinges, an arm extending laterally beyond the panels by at least the width of the panels, and a connector holding the arm to the handhold, the arm being removably clamped to the handhold.

### Claim 2 (depends on 1)

The combination of claim 1 wherein the arm is clamped by a strap.

### Claim 3 (depends on 1)

The combination of claim 1 wherein the safety sign has a height of about 22″ to about 40″, a maximum width of about 10″ to about 13″, and a width near the top of the sign of about 7″ to about 11″.

### Claim 4 (depends on 3)

The combination of claim 3 wherein the arm has a height of 1″ to 8″ and a length several times greater than its height.

### Claim 5 (depends on 3)

The combination of claim 3 wherein the first panel and the second panel are molded of plastic.

### Claim 6 (depends on 5)

The combination of claim 5 wherein the hinge limits opening of the panels beyond about forty degrees.

### Claim 7 (depends on 1)

The combination of claim 1 wherein the arm is formed in multiple segments, a first segment carrying the connector, the connector being a clamp sized to engage a first side of the handhold and a second side of the handhold, and a second segment being moveable relative to the first segment.

### Claim 8 (depends on 7)

The combination of claim 7 wherein the segments are pivoted to each other.

### Claim 9 (depends on 8)

The combination of claim 8 wherein the segments are pivoted by a bolt.

### Claim 10 (depends on 7)
