Definitions

  • the present invention relates to an easily assembled and installed packet curtain.
  • packet curtains conventionally comprise a supporting device, provided for coupling to a top side of the window or window holder supporting construction, on which the curtain is to be mounted, as well as a frame which is provided with a top side associated with the mentioned supporting device.
  • the latter usually comprises a section member element which is horizontally fixed to the window or window holder bearing construction and which supports at least two coaxial pulleys, which have their axes arranged horizontally and spaced from one another in the width direction of the curtain fabric or cloth element.
  • the number of the mentioned pulleys can vary, depending on the cloth element width.
  • a thread-like element is provided which has its top end fixed to one of said pulleys and its bottom end fixed near the bottom side of the cloth element.
  • Each thread-like element is moreover coupled, along the length thereof, to a face or surface of the cloth element by vertical rows of eyelet elements, fixed to the cloth element, which eyelet elements are slidably traversed by the thread-like element.
  • the cloth element is progressively wound up, and collected in a bellows like configuration, because of the pulling force exerted thereon by the thread-like element.
  • the cloth element in particular, is unwound by operating or turning the pulleys in a turning direction causing the thread-like elements to be progressively unwound.
  • This operation is a comparatively complex one and it frequently requires skilled operators.
  • this method includes a very complex step for coupling-removing the top end portions of the thread-like elements and related pulleys.
  • the thread-like elements can be wound with different diameters, i.e. in different winding amounts, thereby causing the bottom side of the cloth element to be arranged in a slanted attitude instead of a precise horizontal attitude.
  • the aim of the present invention is to overcome the above mentioned problems, by providing such a packet curtain in which the cloth element can be quickly and easily coupled to/disengaged from its supporting device.
  • a main object of the present invention is to provide such a packet curtain in which the elements coupling the cloth element to the winding-unwinding pulleys can be coupled in a very simple and quick manner.
  • Another object of the present invention is to provide such a packet curtain which is very reliable and safe in operation.
  • Yet another object of the present invention is to provide such a packet curtain in which the cloth or fabric element can be wound/unwound in a very even manner, so as to always hold the bottom edge of the cloth element in an accurate horizontal attitude.
  • an easily assembled and installed packet curtain comprising a supporting device including winding means, in turn including at least a horizontal axis pulley which can be rotatively driven about a rotary axis thereof, and a cloth element having a top side coupled to said supporting device and provided, at said pulley, with a winding element having one end portion thereof coupled, near the bottom side of the cloth element and slidably connected, along the length thereof, to a face of said cloth element along a substantially vertical direction, characterized in that said winding element is provided, at its top end portion thereof, with a coupling element and in that said pulley is provided with gripping means for automatically gripping, at the start of the rotation of said pulley with said cloth element in a fully unwound condition, said coupling element to cause the winding element to be progressively wound on said pulley, said pulley comprising moreover
  • the packet curtain according to the present invention which has been generally indicated by the reference number 1, comprises a supporting device 2, provided for connection to the top side of the window or window holder frame, on which the packet curtain is to be mounted, as well as a cloth or fabric element 3 which is associated, at its top side, with said supporting device 2.
  • the supporting device 2 comprises moreover a section member 4, provided to be horizontally connected to the window or window holder bearing construction, on which the packet curtain is to be mounted, and which supports at least two pulleys 5, coaxial to one another, which have their common axis horizontally arranged and which can be rotatively driven about said horizontal axis.
  • said pulleys 5 are keyed on a polygonal cross-section shaft 6, which is supported by said section member 4 by means of arms 7 and which can be rotatively driven about its rotary axis by a conventional driving device, such as, for example, a drum rigid with said shaft 6 and which can be turned by a pulling driving force provided on a chain or belt element, partially entrained about said drum, not shown for simplicity.
  • a conventional driving device such as, for example, a drum rigid with said shaft 6 and which can be turned by a pulling driving force provided on a chain or belt element, partially entrained about said drum, not shown for simplicity.
  • the pulleys 5 are spaced from one another in the width direction of the cloth element 3, and the number thereof can be varied depending on the width of the cloth element 3.
  • the cloth element 3 comprises, for each said pulleys 5, a winding element which preferably includes a web or strip like element 10, which is in turn coupled, at the bottom end portion thereof, near the bottom side of the cloth element 3 and being provided, at its top end portion, with a coupling element 11 which can be automatically latched or engaged by gripping means 12 as suitably provided for each said pulleys 5.
  • Each strip element 10 is slidably coupled, along the length thereof, to a face of the cloth element 3, since each said strip-like element slidably passes through a vertical row of eyelet elements 13 fixed to a face of the cloth element 3.
  • the bottom end portion of the strip-like element 10 can be coupled near the bottom side of the cloth element 3 by a hook element 14 engaging through a slot 15 correspondingly associated with the cloth element 3, so as to provide a removable type of coupling of the bottom end portion of the strip like element 10 and bottom side or edge of the cloth element 3.
  • the coupling element 11 in particular, is provided with a substantially T-shape, the central leg of the T being connected to the top end portion of the strip-like element 10, and the two transverse legs of the T laterally projecting from the strip-like element 10.
  • the coupling element 11 has moreover a stiffness greater than the flexure stiffness of the strip-like element 10, and being suitably curved along the extension thereof.
  • a supporting eyelet element 16 is connected, for holding the coupling element 11 at a position suitable for engagement by the gripping means 12.
  • Said supporting eyelet element 16 is provided with a projection or lug 30, adapted to engage in a suitable recess 31, provided on the arms 7.
  • each pulley 5 comprises a pulley groove 17, for engaging and holding therein the strip-like element 10, as said strip-like element 10 is wound, said groove being laterally delimited by two side walls 18a and 18b of disc-like configuration.
  • the gripping means 12 comprise a spiral recess or hollow 19a, 19b which is formed in the side walls 18a and 18b starting from the periphery of said side walls.
  • each pulley 5 is provided with locating means for properly locating the coupling element 11 on the bottom of the groove of the pulley at the start of the winding of the element 10 on the pulley.
  • said locating means comprise a projecting push-button 40, which projects on the bottom side of the wall 18a and which is arranged at one end of a resiliently flexible tongue 41, formed on said wall 18a.
  • the push-button 40 and tongue 41 operate to hold the coupling element 11, which, upon engaging by the recesses 19a and 19b will project inwardly of the push-button 40 due to the resilient flexibility of the tongue 41, tightly adhering on the bottom of the groove of the pulley 5 at the start of the winding operation, thereby providing a very even winding of the winding element 10.
  • the section member 4 of the supporting device 2 and bottom side of the cloth element 3 are provided with mutually engaging means of a removable type for allowing, in a very simple and quick manner, the cloth element to be removed from and reconnected to its supporting device 2.
  • Said mutual engagement means are preferably constituted by a tearing strip, for example of the VELCRO type, including two elements of which an element 20 is seamed or coupled in any other known manner near the top side of the cloth element 3, and a further element 21 which is coupled to the section member 4 of the supporting device 2.
  • the strip-like element 10 can be fully disengaged or unthreaded from the eyelet elements 13, by disengaging its hook-like bottom end portion 14 from the elongated slot 15.
  • the cloth element 3 can be washed without any problems.
  • the coupling element 11 After engagement with the recesses 19a and 19b, the coupling element 11 will leave, as disclosed, the push-button 40 thereby properly arranging on the bottom of the groove of the related pulley, where it will be held by said push-button 40.
  • the rotary driving in the winding direction of said pulleys 5, will cause the strip-like element 10 to be progressively wound about said pulleys 5, thereby the curtain will be packaged.
  • a further advantage of the packet curtain according to the present invention deriving from the use of a strip-like element to cause the curtain to be wound and unwound, is that it is possible to wind in a very even manner the strip-like elements thereby allowing the curtain cloth element to be evenly brought to its packet-like configuration, while holding its bottom side or edge in a perfect horizontal condition.
