Abstract: A longitudinal joint forms 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 the relative rotation to one another with respect to the pivot point (6), depending on the distance between first and second passage surfaces (2,3).

Abstract: Moving ramp for the transportation of people and/or goods, comprising a moving belt (1) limited between upper and lower fixed plates (3) for loading and unloading. The moving belt is constituted by a plurality of inclined pallets (4-4?), which are parallel to the noticeably horizontal lower fixed plates (3), having said pallets the inclination of the moving belt (1).

Abstract: The invention relates to a system having: a first longitudinal member and a second longitudinal member arranged symmetrical to the first longitudinal member in relation to a longitudinal mid-plane of the conveyor system, to define a forward movement track and a return track of the rollers (4); a connecting crossbeam (6) for connecting the longitudinal members. The longitudinal members have: an upper surface defining the forward movement track (2) on which the rollers (4) roll; a lower surface defining the return track (3) on which the rollers (4) roll; an inner surface provided with means for fixing the longitudinal members; an outer surface. The first longitudinal member is connected to the second longitudinal member by means of a connecting crossbeam (6) to ensure a necessary tolerance between longitudinal members.

Abstract: Auxiliary drag mechanism at variable speed, consisting of a variable pitch worm being geared with connection means of the components to be moved, at least during part of their path of travel, at variable speed. The worm is mounted between two end supports (8) and at least one intermediate support (9), whose supports leave free the gearing area between the connection means and the worm, along said worm.

Abstract: Load-bearing structure of a people and/or goods transport system, comprising a mobile band, blades/rungs containing a roller; two side beams; a central body in the form of a sheet having: an upper connection surface to connect the side beams through connection elements; a lower sealing surface parallel to the upper connection surface, at a level below the upper connection surface, to define a closure of the load-bearing structure. The two side beams have a lower connection surface to connect with the central body through connection elements.
