Constructive disposition introduced in domestic ladder

摘要

Constructive disposition introduced in domestic ladder, more precisely, it is domestic ladder (1) of the type used to aid in the domestic tasks or minor repair maintenance; said ladder (1) comprises a main profile (2) format in the inverted "U" configuring a A pair of longitudinal rectilinear sections (SI) and (S2) which are interconnected by a lateral segment (S3).Which have cross section a.The rectangular; linking the rectilinear segments (S1) and (S2) is set across a pair of plates (CP) that form the steps (d) of the ladder (1), as well as,Is installed on the transverse axis (3) for the assembly of the front wall (4a) of the upper platform (4) of the ladder (1); main profile (2) provides both sides flat sides (2a) and close to the lateral segment (S3), a pair of holes (2b) for the assembly of axles (5) and the fixing of the profiles of The support (6a) and (6b) and pivot points (P1) and (P2); each profile support (6a) and (6b) shows.Also, the cross section B.B rectangular and height (y) identical to the height (x) of the rectilinear segments (S1) and (S2) of the main profile (2),And on the sides (6c) are charged holes (6D) corresponding with the holes (2b) of the main profile (2) for the assembly of the axles (5); the alignment of the holes (2b) of the main profile (2) with holes (6D) of the profiles of support (6a) / (and articulation points (6b) P1) / (P2) of the profiles (6a) / (6b) promotes partial juxtaposition of flat faced side (6c) of the profiles of theSupport (6a) / (6b), together with the flat side faces (2a) of rectilinear segments (S1) and (S2) by reducing the total width (W2) of the ladder (1) in relation to total width (W2) of the ladder (1) in the open position cooperating with the storage and transport of the same
