Abstract

Traction device for roller shutters, of the type of those that are embedded in the wall and in which, by means of a crank, the winding of the corresponding traction cable of the shutter is caused on a pulley, characterized - and this is the first of the claimed characteristics - because the lid that closes the box or casing of the device has, on its internal face, two projections: one, on which is mounted, without possibility of rotation, a washer provided with teeth on its face frontal; and another, larger than the previous one, which constitutes a second box mode, equipped, in turn, with its corresponding removable cover and inside which a second washer similar to the first located so that its teeth are housed faced to the latter, a spring that constantly drives the first toothed washer against the second and a pulley for the winding of the blind's traction cable, such pulley and second washer being mounted on a threaded rod, whose head, provided with the corresponding opening for the introduction of the actuating handle of the device imprisons that second washer and the spring, protrudes out through the hole to the effect practiced in the center of the cover, in such a way that, when actuating the crank, rotates the threaded rod together with the pulley and the second washer, whose teeth slide over those of the first fixed washer, while, when the crank is stopped, that prime the washer acts as a ratchet or blocking element of the device when its teeth are encased in those of the second washer.
