## Abstract

A guard device is designed to be fitted around a signpost to provide a barrier against persons attempting to climb the signpost. A pair of mating guard members each have a mating edge for engagement with the mating edge of the other guard member, and the mating edges each have a central recess forming an opening with the other recess for fitting around a signpost. Fastener devices such as bolts secure the guard members together with the opening in gripping engagement with the signpost. The guard members when secured together form a continuous barrier surface projecting outwardly from the signpost.

## Claims

### Claim 1

A guard device for impeding access to signs via signposts, comprising:
a pair of guard members each comprising a semi-circular, substantially flat sheet member having a straight mating edge for engagement with the corresponding straight mating edge of the other guard member to form a substantially continuous guard surface;
each mating edge having a central recess for alignment with the central recess in the mating edge of the other guard member to form a circular opening for fitting around a signpost;
each recess having a semi-cylindrical flange projecting downwardly from said recess in a direction transverse to said guard surface, the flanges cooperating when the guard members are secured together to form a generally cylindrical collar, said collar comprising means for gripping engagement with a signpost; and
securing means for securing the guard members together with the opening and collar in gripping engagement with the signpost and the guard surface formed by the members projecting outwardly from the signpost in a generally radial direction to form a barrier against persons climbing the signpost.

### Claim 2 (depends on 1)

The device as claimed in claim 1, wherein the opening is of smaller dimensions than the cross-sectional dimensions of a signpost around which it is to be fitted.

### Claim 3 (depends on 1)

The device as claimed in claim 1, wherein said members have an outer diameter of at least 60 inches.

### Claim 4 (depends on 1)

The device as claimed in claim 1, wherein said members are of sheet metal.

### Claim 5 (depends on 1)

The device as claimed in claim 1, wherein said members form a slightly conical shape with said opening at the center.

### Claim 6 (depends on 1)

The device as claimed in claim 1, wherein each guard member has a pair of attachment flanges each projecting downwardly from the straight mating edge of said member at a location spaced from said semi-cylindrical flange, one of said attachment flanges of each member being located on one side of said semi-cylindrical flange and the other attachment flange being located on the other side of said semi-cylindrical flange, said attachment flanges having openings which are aligned when the members are secured together in mating engagement, said securing means comprising fastener means for extending through said openings.

### Claim 7

A guard device for impeding access to signs via signposts, comprising:
a pair of guard members each comprising a sheet member having a straight mating edge for engagement with the corresponding mating edge of the other guard member to form a substantially continuous guard surface;
each mating edge having a central recess for alignment with the central recess in the mating edge of the other guard member to form an opening for fitting around a signpost;
securing means for securing the guard members together with the opening in gripping engagement with the signpost and the guard surface formed by the members projecting outwardly from the signpost to form a barrier against persons climbing the signpost; and
a pair of attachment flanges projecting downwardly from the straight mating edge of each of said guard members at locations spaced from said recess, one of said attachment flanges being located on one side of said recess and the other attachment flange being located on the other side of said recess, said attachment flanges having openings which are aligned when said members are secured together, said securing means comprising attachment bolts for extending through said aligned openings.
