Claim 1

Independent Claim 184 words

A safety guard apparatus comprising: two or more units to be spaced apart on a pitched roof and secured together by a rail fastened to each unit, each unit having a first elongate member with a second and a third elongate member mounted in spaced relation thereon and pivotally connected thereto, said second and third members being interconnectible together, each first member having at one end fastening means by which the unit can be supported on a roof member with its second member serving as a tie for the third member which serves as an upright guard rail support; said first members each having a tubular collar rigidly fixed thereto at an end opposite said fastening means with a tubular axis of said collar at a right angle to the first member; and a fourth rigid elongate member engaged through and in sliding engagement with each said tubular collar, each said fourth member being positionally adjustable with respect to its collar such that a lower end thereof may abut a vertical wall below said pitched roof to support its respective unit above said roof.

Claim 2

Dependent Claim 184 words

A safety guard apparatus comprising: two or more units to be spaced apart on a pitched roof and secured together by a rail fastened to each unit, each unit having a first elongate member with a second and a third elongate member mounted in spaced relation thereon and pivotally connected thereto, said second and third members being interconnectible together, each first member having at one end fastening means by which the unit can be supported on a roof member with its second member serving as a tie for the third member which serves as an upright guard rail support; said first members each having a tubular collar rigidly fixed thereto at an end opposite said fastening means with a tubular axis of said collar at a right angle to the first member; and a fourth rigid elongate member engaged through and in sliding engagement with each said tubular collar, each said fourth member being positionally adjustable with respect to its collar such that a lower end thereof may abut a vertical wall below said pitched roof to support its respective unit above said roof.

Claim 3

Dependent Claim 157 words

A safety guard apparatus for a pitched roof comprising: a unit having a first elongate member with second and third elongate members pivotally mounted in spaced relation thereon, said second and third members being interconnectible together, the first member having at one end fastening means by which the unit can be supported on a roof member with said second member serving as a tie for the third member which serves as an upright guard rail support; said first member having a tubular collar rigidly fixed thereto at an end opposite said fastening means with a tubular axis of said collar at a right angle to the first member; and a fourth rigid elongate member engaged through and in sliding engagement with said tubular collar, said fourth member being positionally adjustable with respect to said collar such that a lower end thereof may abut a vertical wall below said pitched roof to support said unit above said roof.

Claim 4

Dependent Claim 157 words

A safety guard apparatus for a pitched roof comprising: a unit having a first elongate member with second and third elongate members pivotally mounted in spaced relation thereon, said second and third members being interconnectible together, the first member having at one end fastening means by which the unit can be supported on a roof member with said second member serving as a tie for the third member which serves as an upright guard rail support; said first member having a tubular collar rigidly fixed thereto at an end opposite said fastening means with a tubular axis of said collar at a right angle to the first member; and a fourth rigid elongate member engaged through and in sliding engagement with said tubular collar, said fourth member being positionally adjustable with respect to said collar such that a lower end thereof may abut a vertical wall below said pitched roof to support said unit above said roof.

Claim 5

Dependent Claim 61 words

Apparatus as claimed in claims 1 or 2, wherein the fourth member has a lengthwise series of apertures to be aligned one at a time with an aligned set of apertures in the collar and secured by a pin or bolt located therethrough to hold them in said position whereby the fourth member can be length-adjusted relative to the first member.

Claim 6

Dependent Claim 24 words

Apparatus as claimed in claims 1 or 2, wherein the outer end of the third member is provided with a guard rail fastening mechanism.

Claim 7

Dependent Claim 23 words

Apparatus as claimed in claims 1 or 2, wherein means are provided on the third member to hold a plank upright on side.

Claim 8

Dependent Claim 22 words

Apparatus as claimed in claim 5, wherein the means are in the form of lugs extending laterally out from the third member.

Claim 9

Dependent Claim 22 words

Apparatus as claimed in claim 6, wherein the lugs are apertured to accept screw fastenings therethrough to be screwed into the plank.

Claim 10

Dependent Claim 21 words

Apparatus as claimed in claims 1 or 2, wherein the fourth member has an angled foot plate at its lower end.
