20110315476 | Ladder Stabilising Device - A stabilising device for stabilising a ladder relative to a structure, the stabilising device comprising a main body having associated therewith a first mount which in use can be mounted to the ladder and a second mount which in use can be mounted to the structure wherein said main body comprises an elongated member said mountings being operatively secured thereto in spaced relation therealong. | 2011-12-29 |
20110315477 | ELECTROADHESION DEVICE FOR IMPROVING EXTENSION LADDER STABILITY - A method of stabilizing a ladder is provided by attaching one or more electroadhesive devices to an attachment point on the ladder and contacting the device to a surface such as a wall or the floor. The electrostatic force achieved by applying a voltage difference in the device provides decreased ladder slip angles or increased shear forces required to create ladder slippage thereby improving ladder stability. | 2011-12-29 |
20110315478 | Rolling Toe Assist - A ladder, system, and methods are disclosed. The ladder is used on a steep-pitched roof and has a first section with rungs, a second section connected to the first section, a third section connected to the second section, and a paw pivotally connected to the third section. The third section has a length less than or equal to a length of the second section, and the third section also has a length less than a distance between a first rung of the rungs and an end of the first section. The ladder can be used in a system that utilizes the ladder and a roof anchor apparatus, where the roof-anchor apparatus has two portions and two shoes interconnected to the portions. A method includes positioning the ladder and then positioning the roof anchor apparatus, on and over a steep-pitched roof, respectively. | 2011-12-29 |
20110315479 | Article Storage Facility - A vertically movable work platform is suspended and supported by a plurality of suspension wires fed out from one or more of winding rotating bodies which is rotated such that the vertically movable work platform is vertically moved by the rotation of the one or more of winding rotating bodies. A support for receiving and supporting the lowering vertically movable work platform at a work height, and a stopper for preventing the rotation of the winding rotating body in a direction which tends to lower the vertically movable work platform when the vertically movable work platform reaches the work height are provided. | 2011-12-29 |
20110315480 | ASCENDER/DESCENDER APPLIANCE FOR CLIMBING AND DECENDING ON A ROPE - An ascender/descender appliance for ascending and descending on a rope, comprising a body having attachment means to be connected to the user's harness and a clamping device able to be released on load. The clamping device is arranged outside the body and comprises a chain of metal links constituted by a succession of friction elements articulated on one another by connecting rods to form a series of gaps for the rope to pass in zigzag manner. Means are associated with the top link to trigger clamping of the ascender device. | 2011-12-29 |
