The invention relates to an end stop device for blind-rolling shafts, which can be used in a wide range of blinds regardless of the length thereof. The inventive device has a high breaking strength since a cylindrical helical pinion has to engage with only a worm, such that the life of the device, in terms of the number of cycles that withstand stresses, is very long. The aforementioned cylindrical helical pinion comprises a special configuration formed by two parts. In addition, the assembly that defines the end stop is equipped with a device for counting the number of times that the blind shaft rotates.

This invention relates to a compact transverse joist for blinds meant to be installed in the narrow cavity defined by the window frame with the masonry, with a front opening for the handle used to raise the blinds. The special compact configuration of the hoist and the presence of a window opposite the inlet window for the cable allows threading the cable without opening the cover. This hoist characterises a special configuration that optimises the space inside the case in the case segment that corresponds to the winding and the case segment corresponding to the main conical gear so that a height difference can be determined required for the presence of the second window.

The object of this invention consists of an autolocking closure for awning boxes, this is, a closure constituted on a box that houses the shaft on which an awning fabric is wound, provided with a load bar that locks itself in the box. The invention uses a configuration of the box and the load bar such that it closes the box with the load bar without a direct manipulation of the load bar. In case of a vertical elevation of the load bar it is associated to folding arms, being locked in the box by a simultaneous double sliding and rotation motion so that it is automatically and completely locked, while if it is attached to the end of hinged arms the box is closed directly by locking the bar in the box.
