In one embodiment, an attachment apparatus for a ladder includes a main support adapted to be coupled to the ladder approximately parallel to the rungs. The main support includes a first coupling member proximate a first one of the elongated rails of the ladder and a second coupling member proximate another one of the elongated rails. The attachment apparatus further includes first and second support modules removeably coupled to the first and second coupling members, respectively. Each support module includes a support member including a proximal end and a distal end, and a support arm attached to the support member proximate the distal end and projecting outwardly therefrom in a first direction. The support member includes at least one projecting portion that is removeably coupleable to the corresponding one of the first and second coupling members.
La présente invention concerne un appareil et des procédés de fixation d'échelle. Dans un mode de réalisation de l'invention, un appareil de fixation pour échelle comprend un support principal conçu pour être couplé à l'échelle approximativement parallèlement aux échelons. Ce support principal comprend un premier élément de couplage à proximité d'un premier rail effilé de l'échelle et un second élément de couplage proximité d'un autre rail effilé.
