Abstract
A bracket device for attachment to a thin walled section includes a main member having an operating member, and an attachment hook extending from a proximal end of the operating member which in use engages with the thin walled section, and a locking wedge associated with the attachment hook which slides in relation to the attachment hook to a locking position to create a reaction force between the attachment hook and the thin walled section.
Claims2
A step for attachment to a utility pole having a thin wall section, the step comprising:
- a main member having a step member with a flange portion formed at a proximal end thereof, a free end at a distal end thereof, and an upwardly facing support surface for a user to stand on, between said free end and said flange portion, and a single attachment portion integral with said step member extending from a face of said flange portion and terminated in a hook extending out from the flange, in alignment with said step member, then up, which in use extends through an aperture provided in a wall of said thin walled section, and
- a wedge member which is adapted to slide in a transverse relation to said attachment portion and interpose between said flange and said thin walled section, and abut against a face of said flange portion when in a locking position, to be driven downward to create a compressive force between said hook and said wedge member with said thin walled section therebetween to hold said step member in place, said wedge member comprising a body formed with an enclosed slot, and having an inner face and an outer face inclined relative to each other at an angle of from 3.5 to 5 degrees, said inner face and said outer face each being formed with a concave channel of substantially the same shape in cross section along a full length thereof.
In combination, a utility pole having a thin walled hollow section with a plurality of circular apertures through said thin walled hollow section for mounting steps to said pole, and at least one step comprising:
- a step for attachment to a utility pole having a thin walled section, the step comprising:
- a main member having a step member with a flange portion formed at a proximal end thereof, a free end at a distal end thereof, and an upwardly facing support surface for a user to stand on, between said free end and said flange, and a single attachment portion integral with said step member extending from a face of said flange portion and terminated in a hook extending out from the flange, in alignment with said step member, then up, and which extends through an aperture provided in a wall of said thin walled section and up behind said wall, and
- a wedge member which is adapted to slide in a transverse relation to said attachment portion, interposed between said flange and said thin walled section, and abutting against a face of said flange portion creating a compressive force between said hook and said wedge member with said thin walled section therebetween to hold said step member in place, said wedge member comprising a main body formed with an enclosed slot, and having an inner face and an outer face inclined relative to each other at an angle of from 3.5 to 5 degrees, said inner face and said outer face each being formed with a concave channel of substantially the same shape in cross section along a full length thereof, said hook passing through said enclosed slot.
