ABSTRACT:
A post step gripping device, includes a flat planar platform for receiving the feet of a user, a horizontal support shaft attached by brackets and an intermediate support member to a first end of the platform, a pair of opposite arms pivotally attached to and slidably movable along the support shaft for attaching the device to a post, and a brace mounted to the bottom of the platform and a pair of angled plates attached to the pivotal connection of the arms to the support shaft for securing the platform in a substantially transverse position relative to the post. The brace, the angled plates and the arms operate in conjunction with the weight of the platform and/or the weight of the user standing on the platform to secure the device to the post. The device may also include a step member pivotally attached to an opposite second end of the platform and having a substantially U-shaped bar for receiving a foot of the user. The arms, brace and step member are pivotally movable between a retracted storage position, which permits the device to be stored in a convenient fashion, and an extended deployed position, which permits the device to be mounted to the post.
