DESCRIPTION OF THE INVENTION

what

ANTÓNIO PERMUY PEDRE, Spanish, industrial, resident in Manifos Aldea - <? 1, Fene, A Coruña, Spain, intends to obtain in Portugal, for "LIFT WINDOW FOR BLINDS".

The present invention relates to a roller shutter lathe.

The present invention, as expressed in the title of this specification, consists of a roller lathe.

In general the object of the present invention is a clutch installed inside a box and driven by a crank.

Specifically, the clutch is

by a disk with its corresponding descending diameter axis for the fastening, at the free end of the drive crank, which disc has an annular projection on one of its faces with an open section in which there is a floating part small nail. In the outer zone of the projection a crown is provided with its outer contoured toothing, while in the channel which determines the circular projection and its axis, a projection is disposed on one of the faces of the reel of the rope, this projection of the reel a small radial shoulder which is disposed in the open section of the disc protrusion and is susceptible of coming into contact with the small floating nail or one of the ends of the open circular protrusion. The ring gear is in contact with a tongue fixed in the housing two mechanisms.

One embodiment variant of the

(I.e.

The object of the present invention is to replace said pawl by a locking lever which does not alter the structure of the invention and which is solely and exclusively one of the multiple embodiments which may derive from the structure of the lifting lathe for

shutters, object of the present invention.

In order to complete the description which is to be given hereinafter and in order to assist in the better understanding of the features of the present invention, the following description is attached to a set of drawings in which the following is represented:

Figure 1 - corresponds to a perspective view of the entire lift assembly assembly, disassembled.

Figure 2 - corresponds to a perspective view of the winch with all its elements assembled, and in which a corfe was made to visualize all the elements of which it appears, |

As can be observed, by the plans

a gearbox 1 which is comprised of a disc 2 provided in a pair of faces of a protruding shaft 3 with a stepped diameter C | descending end capped on a hexagonal rod 4 which functions as the coupling element at the end of the actuating crank 5,

The disc 2, on the front face of which the axle 3 protrudes, has a pivot projection 6 having an open section 7. In the open section 7 a small floating flange 8 engages and on the outer surface of the flange 6 a crown 9 engages which has its toothed outer periphery.

In the channel produced by the protrusion 6 and by the axis 3 a circular protrusion 10 which radially / radially engages a shoulder 11, the protrusion 10 β being the protrusion 11 being disposed on one of the faces of the carriage 12. All this in such a way that. the shoulder 11 is located in the open section 7 and in contact with one of the ends of the flange 6 and with the knob.

floating point 8 «

The entire clutch assembly disposed in the groove 1 is housed in a housing 13. On the housing 13 and the housing 11 is provided a bolt 14 with its corresponding fixing axis, which bolt acts on the crown 9, locking its movement in one direction, while allowing its free rotation in the other,

The clutch assembly is mounted at its ends by corresponding rims 15, at the bottom of the housing 13 and the cover 16, which covers the housing 13. The cover 16 is covered by an embellishment cover 17, the cover and the overlap having the hole corresponding to the passage of the hexagonal lever 4 of engagement with the crank 5, which lever 4 is covered by the crank plug 18,

The rope 19 is attached at one of its ends to the carriage 12 on which it is to be wound and unrolled *

With this constitution, the operation of the elevator lift for shutters is as follows

In actuating the crank 5, the shaft 3 of the clutch body 2, in the upward direction of the blind, the said disc 2 draws the carriage 12, since its shoulder 11 engages one end of the circular protrusion 6 of the disc 2 , releasing the small floating nail 8 and thereby leaving the crown 9 retained by its tongue 14

When the ascent is achieved, there is a slight retraction of the clutch due to the sheer weight of the shade, causing the shoulder 11 to depress the small flap 8, against the crown 9 retained by the pawl 14, with which it locks set.

By actuating the crank 5 in the opposite direction to lower the blind, the whole assembly rotates in a solid manner, while the pawl 14 jumps freely on the teeth

55,643

Iv / l84,154

of the crown 9, until the downward movement stops, at which time the pawl 14 again acts on the crown 9, thereby blocking any unwanted rotation.

The clutch can be operated in both directions of rotation at will, simply by changing the position of the parts.

As a variant of embodiment, it was provided that instead of the tongue-shaped tongue 14 to retain a direction of rotation in the toothed ring 9, there is provided a locking wing located in the same place as said pawl 14.

Likewise, the drive of the crank 5 can be made directly on the shaft or said crank 5 acting on a reduction gear wheel, which engages with the body of the clutch 2, i.e. with the periphery of the disk 2.

The deposit of the first application for the invention described above was carried out in Spain - as Utility Model - under ο δδ. 274-128 on August 30, 1983.
