(57) A device helping to close sliding doors, comprising a frame (1) mounted in the inner
part of an end of a guiding channel (2a) being finished off by opposing flanges in
its ends, which is part of a conventional guide-profile (2) of the assembly of sliding
doors (3) and which is inherent in the displacement rail (2b) of the wheels (6) of
the sliding door (3), in whose frame (1) a closing damper (4) is installed and a swinging
trigger (5) is adapted to engage with a side hook (6a) of the wheel (6) of the sliding
door (3), which is forward according to the closing direction, and there is a tension
spring (7) having an end attached to the swinging trigger (5) and it is tightened
when opening the sliding door; taking into account that the reference of forward of
the device will be understood as the first part the wheel reaches in the advancing
direction of the closing of the sliding door, and vice versa. In the device exits
a flexible brace (8) having an end attached to the swinging trigger (5) and, in a
rear pulley (9), it forms a flat loop along which it extends rearwards in the rear
pulley (9), leaves it forwards and it extends out of the frame (1) locating another
end being engaged to a removable carriage (10) being susceptible to receive the rear
end of an independent tension spring (7) being located out of the frame (1) and having
a forward end attached to an outer anchorage (11) being susceptible to be fixed along
the guiding channel (2a) selectively.
