Ladder attachment apparatus and methods are disclosed. In one embodiment, an attachment apparatus (100) for a ladder (104) includes a main support (120) adapted to be coupled to the ladder approximately parallel to the rungs (102). The main support (120) includes a first coupling member (150) proximate a first one of the elongated rails (106) of the ladder and a second coupling member (150) proximate another one of the elongated rails. The attachment apparatus further includes first (130A) and second (130B) support modules removeably coupled to the first and second coupling members, respectively. Each support module includes a support member (1323) including a proximal end (134) and a distal end (136) attached to the support member proximate the distal end and projecting outwardly therefrom in a first direction. The support member(132) includes at least one projecting portion (144) that is removeably coupleable to the corresponding one of the first and second coupling members.
La présente invention concerne un dispositif et des procédés de fixation d'échelle. Dans un mode de réalisation de l'invention, un dispositif de fixation destiné à une 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 près d'un premier montant allongé de l'échelle et un second élément de couplage près d'un autre montant allongé. Ce dispositif de fixation comprend aussi un premier et un second module couplé démontable au premier et au second élément de couplage, respectivement. Chaque module de support comprend un élément de support comprenant une extrémité proximale et une extrémité distale et un bras de support fixé à l'élément de support près de l'extrémité distale et faisant saillie vers l'extérieur de celui-ci dans une première direction. Cet élément de support comprend au moins une partie faisant saillie qui peut se coupler démontable à l'un des deux éléments de couplage correspondant.
