Definitions

  • the invention concerns a device to be used with cords to raise or lower vertically-operated curtains of various kinds such as those that are pleated or rouched, Venetian blinds and others.
  • Cord lengths obviously differ allowing for the fact that they are fixed at different points on the lower cross-piece in relation to the side from which they are pulled.
  • the curtain is fixed at the desired height by means of a mobile roller which, due to cord friction, moves in the direction of cord movement becoming wedged between an op ⁇ posing wall and the cords themselves, so fixing them. It often happens, however, that the roller gets out of place so that the cords cannot be fixed and may even be freed because of one overlying another.
  • Subject of the invention is a device for working vertically operated curtains by means of cords fixed at the lower edge of the curtain and pulled passing, in doing so, through means of transmission placed on a headpiece at the top of the curtain.
  • the upper ends of the cords pass round two or more opposing pulleys, one or more of which are supported by the curtain's headpiece and one or more by a carriage sliding axially in relation to said headpiece.
  • a chain is fixed and after said chain has passed round a means of transmission on the headpiece,oppo ⁇ site (in relation to the carriage) to the pulleys carried by the headpiece, it drops down to a position within reach of the user's hand. Therefore, by pulling said chain the carriage moves causing the curtain to be drawn up while, when releasing the chain,
  • Curtain movement is multiplied in relation to chain move ⁇ ment in a ratio the value of which differs according to the number of opposing pulleys mounted respectively on the head ⁇ piece and on the carriage, and according to whether the upper end of each cord is fixed to said headpiece or to said carriage.
  • the value of said ratio is 2 to 1 if only one pair of pul- leys is used, 4 to 1 if there are two pairs of pulleys or 6 to 1 if there are three pairs of pulleys, or else 3 to 1 if the upper end of each cord is fixed to the carriage and so on.
  • cords may be one or more cords according to the width of the curtain, and they are fixed to the end of the lower cross- piece to which the curtain too is fixed, and possibly at in ⁇ termediate points. It is an advantage for the cords to be of a constant length as their lower ends are fixed to one of the ends of the cur ⁇ tain's lower cross-piece (at the end opposite to the position of the pulley mounted on the upper headpiece) and they are carried up to the top headpiece over means of transmission which, as the case may require, are mounted at the other end of the curtain's lower cross-piece or at intermediate points.
  • Fixing the curtain at different heights is done by means of a transmission block in which there is a downward-facing groove made inside a vertical channel whose end slopes slight- ly outward, the chain sliding in this channel. , The end of i • . the groove is smaller than the diameter of the little balls placed at regular intervals along the chain.
  • the chain is pulled at an inclination slightly sharper than that of the bottom of the channel, it can slide freely and the curtain can be pulled up or let down but if the chain is set vertically, one of the little balls becomes stuck in the end of the groove and the curtain is thus held firmly in the desired position.
  • the above ratio means that curtains can be raised or low ⁇ ered far more quickly and easily. Length of the cords fixed to the lower cross-piece of the curtain being constant ensures simpler manufacture and in ⁇ stallation.

  • the pleated curtain 10 hangs from the upper headpiece .50 onto whose two ends blocks 11 and 20 are respectively forced.
  • the carriage 28 is fitted inside the headpiece.
  • Block 11 is a body of hard plastic material comprising a
  • the carriage 28 is a block of plastic material which also has a comb and teeth 31 between which are placed the pulleys 29 freely rotating round the small shaft 30 pressed in trans- versally in relation to said teeth 31.
  • the cross-piece 38 at the lower edge of the curtain 10, contains holes 37.
  • Said lower cross-piece 38 is connected to the (upper headpiece
  • Cord 17 passes through the hole 37 in the cross-piece 38 and is held there by a knot 40.
  • said cord has passed through holes made in the pleats 19 of the curtain and the hole 39 in the upper headpiece 50, it passes round the race on the pulley 13 in block 11, then round the race on pulley
  • cord 42 starts from a hole at one end of the cross-piece 38, passes from hole 49 at the other end of said cross-piece and having passed round pulleys 51 and 52 in block 11 and in the carriage 28 respectively, it is then held in said block by the knot 53.
  • the block 20, placed at the other end of headpiece 50, serves to guide the sliding movement of the chain 21 working the curtain, said chain being then fixed at one end, in hole

Abstract

Dispositif servant à ouvrir ou refermer des rideaux à actionnement vertical au moyen de cordons (17, 41, 42) dont les extrémités supérieures passent autour de deux poulies ou plus, placées à l'opposé les unes des autres (13-29, 46, 47, 51, 52), dont une ou plusieurs (13, 46, 51) sont soutenues par le caisson (50) du rideau, et dont une (29, 47, 52) ou plusieurs sont soutenues par un chariot (28) coulissant axialement par rapport audit caisson (50) et relié à une chaîne (21) qui, après être passée autour d'un moyen de transmission (20) monté sur le caisson (50), tombe de manière à pouvoir être tirée manuellement et de sorte que le mouvement coulissant du rideau est démultiplié par rapport au mouvement de la chaîne (21).
