  • Publication number: 20120097481
    Abstract: A ladder attachment includes an elastomeric member having a rigid body including a concave recess created between first and second end legs. First and second gripper wings are connected to the elastomeric member and extend into the concave recess. Each gripper wing has multiple teeth oriented away from the body. The first and second gripper wings are separated from the body by first and second slots. The first and second gripper wings elastically deflect into the first and second slots and toward the body by a force acting on the body. The body has first and second apertures including first and second body angled surfaces oriented at an acute angle with respect to a line extending through the body and perpendicular to a planar body surface. The first and second gripper wings have a maximum thickness at the first and second connecting ends, and thinner first and second free ends.

  • Patent number: 7575097
    Abstract: A ladder attachment including an elongated one piece member preferably molded from an elastomeric material and formed with an arcuate cavity on one side sized to approximately correspond to the outside of a utility pole or tree trunk and having a pair of end parts each formed with a hole sized to receive the upper end of a ladder stile to be mountable crosswise to the upper end of the ladder. A pair of curved slits are formed into the one side of the member each extending around one side of the cavity to form a pair of concentric curved gripper wing portions concentric to the cavity which are drawn together with a strap, which has ends connected together with a cinch to secure the ends together.
