Title (EN) LADDER-TYPE CABLE TRAY
(FR) CHEMIN DE CABLES EN ECHELLE
Abstract:
(EN) A cable tray (20) comprising a pair of generally parallel spaced-apart metal sides (22, 24) and metal rungs (26) extending between the rails (22, 24) at intervals along the rails (22, 24). Each metal rung (26) has opposite ends (28, 30) generally abutting respective side rails (22, 24) and a pair of preformed openings (48, 50) extending inwardly from the opposite ends (48, 50) of the rung (26) lengthwise of the rung (26). A pair of metal mechanical fasteners (32) extend through the side rails (22, 24) and into respective preformed openings (48, 50) in the rung (26) to fasten the rung (26) to the side rails (22, 24). Each of the openings (48, 50) is defined by a rung structure (46) which, as viewed in a cross section taken transversely with respect to the rung (26), extends completely around the perimeter of the opening (48, 50) so that the perimeter of the opening is totally enclosed by the rung structure (46). Each of the fasteners (32) is engageable with the rung structure (46) defining a respective opening (48, 50) for securely holding the rung (26) in fixed position with respect to its respective side rail (22, 24).
(FR) L'invention porte sur un chemin de câbles (20) comportant une paire de rails latéraux métalliques (22, 24) espacés et généralement parallèles et des barreaux (26) reliant les rails (22, 24), à intervalles réguliers le long de ces derniers (22, 24). Chaque barreau (26) présente des extrémités opposées (28, 30) venant généralement buter contre les rails latéraux (22, 24) respectifs ainsi qu'une paire d'ouvertures préformées (48, 50) s'étendant vers l'intérieur depuis les extrémités opposées (48, 50) des barreaux (26), le long de ces derniers (26). Deux éléments de fixation mécaniques (32) traversant les rails (22, 24) viennent s'engager dans chacune des ouvertures préformées respectives (48, 50) des extrémités (48, 50) d'un barreau (26) pour fixer ledit barreau (26) aux rails (22, 24). Chacune des ouvertures (48, 50) est entourée par une structure (46) du barreau, selon une section transversale par rapport au barreau (26), et s'étend intégralement autour du périmètre de l'ouverture (48, 50) de manière à ce que le périmètre de cette dernière soit totalement entouré par la structure (46) du barreau. Chacun des éléments de fixation (32) s'engage dans la structure (46) du barreau (26) percée de son ouverture respective, de manière à en fixer fermement chaque extrémité à son rail latéral respectif (22, 24).
