Definitions

  • the present invention relates to a control mechanism for a roman or panel blind or the like.
  • roman blind will be understood to relate to a flexible panel blind suspended from its upper edge and having a plurality of cords or lines running from top to bottom, sometimes attached to a batten, beam or other reinforcing member at the bottom, by means of which the panel can be raised or lowered. Such blinds when raised, may be gathered into loose folds or pleated or otherwise folded into a small volume. The batten or beam at the bottom provides enough weight to ensure that the panel is stretched out when the control cords are slackened.
  • the present invention seeks to eliminate the above indicated disadvantages by providing a control mechanism for a Roman blind or the like which will make it possible to have only a single control element disposed laterally of the blind, by means of which raising or lowering of the blind can be effected, regardless of the number of cords provided for the movement of the blind itself.
  • a control mechanism for a Roman or like blind comprising a flexible panel suspended from an upper cross member which can be fixed to a wall or a ceiling and within which extend a plurality of control cords connected at one end thereof to the lower end of the blind panel, characterised by the fact that the said control lines are wound on a spool connected for rotation with a sprocket over which passes a chain; this sprocket and spool being rotatably supported by a support body fixable to the said supporting cross member of the blind and provided with locking means engageable by the chain and operable to prevent movement of the chain in the direction of lowering of the blind.
  • One advantage of the present invention is that an embodiment thereof may be formed as a support and actuation mechanism for a Roman blind or the like, which will give the possibility of effecting, in an extremely rapid and simple manner the locking of the blind at the desired height, without the presence of an inconveniently large number of cords which have to pass down one side of the blind.
  • Another advantage of the present invention is that an embodiment thereof may be made as a support and control structure for a Roman blind or the like, which will have significant properties of security and reliability in use. Moreover, with only one actuation member to move the user may nevertheless effect a uniform and precise adjustment of all the cords with which a blind is provided.
  • the Roman blind control mechanism forming the subject of the present invention comprises an upper support 1 formed as an extruded section in such a way as substantially to define an upper channel 2 and a lower channel 3.
  • the upper channel may be fitted plates 4 or other similar elements for fixing the upper support 1 to a wall or a ceiling.
  • the lower channel there is housed a guide section 5 which is connected to the upper end of the panel 6 (pleated panel 6' in the embodiment of Figure 4) and, in practice, supports a plurality of control cords 8 by means of pulleys 7.
  • control cords 8 extend longitudinally down the blind through suitable holes or eyelets provided therein or thereon, and are connected at a lower end to a lower cross bar or batten 9 at the lower end of the blind panel 6 or 6'. At their other end the said control cords 8 are wound on a spool 10 which may be provided with suitable grooves for winding the individual cords in such a way as to keep them all separate from one another.
  • This spool is connected rigidly for rotation with a sprocket 11 which is provided with seatings for receiving the individual links of a chain 12.
  • the chain 12 is formed as a closed loop provided with spaced balls.
  • Other types of chain may be employed, however, providing the links suitably interengage with the sprocket teeth to provide a slip-free interengagement.
  • the said chain may have regularly spaced balls as in Figures 1, 2 and 3 or balls closely adjacent one another as in Figures 4,6,7 and 9. Consequently, the seatings formed by the sprocket teeth, or otherwise formed on the said sprocket may be likewise spaced or close together in such a way as to prevent any possibility of relative slip between the chain and the sprocket.
  • a closed loop of chain 12 is preferred it is by no means essential and a single length of chain, perhaps suitably weighted at the ends, may be provided instead.
  • the spool 10 and the sprocket 11 are supported for rotation by a fixed support body generally indicated with the reference numeral 13.
  • This support body 13 is provided with a projection 14 suitably shaped to engage securely into one end of the upper cross member 1 and has, obviously, a suitable series of openings (not shown) for the passage of the control cords for operating the blind.
  • the support body 13 is advantageously made with a symmetrical structure in such a way that it can be used equally well for blinds with the control cords leading to the left or to the right of the blind panel.
  • the support body 13 has a casing 15 enclosing a part of the spool 10 and the sprocket 11 and which, in its lower part, is provided with a bifurcated housing 16 with a downwardly flaring entrance enlargement 17 terminating in a restricted zone 18 to form a forked seating in which the balls or links of the chain 12 can engage.
  • the locking of the chain can be obtained by means of a shaped spring element 19 which in practice defines a groove or throat in which the balls or links of the chain itself can be fixedly lodged.
  • the user can with a simple movement introduce a link of the control chain into the associated locking seat therefore preventing the chain from moving in a direction corresponding to lowering of the blind.
  • This forked seating 17, 18 or the corresponding spring element 19, is inclined downwardly ensures that by exercising a tension on the chain 12, in a direction corresponding to raising of the blind, the chain 12 can easily be released from engagement in the forked seating.
  • the housing of the support body 13 is formed initially with forked seatings on both sides, one of which is removable upon assembly in such a way as to be able to select left or right hand operation from a common component.
  • the said spool/sprocket unit permits the user to act on a single element, constituted by the chain 12, regardless of the number of control cords provided for the raising and lowering of the blind panel itself, these cords all being wound onto the spool in use as the blind is raised, and unwound from it as the blind is lowered.
  • Rotation, in one sense or other, of the sprocket 11 is achieved by pulling on the chain 12 on one side or the other; this in turn makes the spool 10 rotate with consequent winding in synchronism of all the control cords of the blind, thus causing raising or lowering of the blind.
