| 摘要 |
The present invention relates to a longitudinal joint of the type forming a surface usable as a passage between first and second passage surfaces (2,3) adjacent to one another, usable as walking user passage, the distance between both in the longitudinal direction being variable. The longitudinal joint (1) has transverse slats (4) attached to one another, with a substantially planar upper surface (5), each being attached to the contiguous slats by a pivot point (6) with respect to which they can rotate preserving the continuity of the surface of the longitudinal joint (1). The slats (4) rest on a series of support surfaces (8,9,12), a certain number of slats being hidden under the first passage surface (2), below the level of the upper surface (5), by means of the relative rotation to one another with respect to the pivot point (6), defending on the distance between first and second passage surfaces (2,3). |
