Definitions

  • the present invention relates to an awning roll-up device.
  • Awning roll-up devices which comprise a hollow box-like body, which is typically shaped like a parallelepiped and is elongated longitudinally in horizontal direction; a drum is rotatably supported at its transverse ends, and an awning can be rolled up and unrolled on said drum, for example by means of the action of an electric motor keyed axially to the drum or of a crank which can be operated manually.
  • the awning exits from the box-like body typically through a longitudinal slot formed in the bottom of such body.
  • Such known type of awning roll-up device is typically fixed to a wall of a building above an opening to be covered with the awning, such as for example a window or a French window.
  • the awning By unrolling the awning from the drum, the awning descends toward the floor of the building, thus covering the opening.
  • awning roll-up devices of a known type, arranged side by side and with several aligned individual drums.
  • the aim of the present invention is to solve the above-mentioned problems, eliminating the drawbacks of the cited background art, by providing an awning roll-up device that covers even an opening that has a large horizontal extension.
  • an object of the invention is to provide a device that has low weights and is easy to install.
  • Another object is to provide an awning roll-up device that allows to affect even a space that is horizontally very large and at the same time allows to block all the light that affects said space.
  • Another object is to provide a device that is structurally simple and has low manufacturing costs.
  • an awning roll-up device characterized in that it comprises a frame provided with first and second rotary support means for at least one first drum and at least one second drum, which are arranged so as to approximately face each other horizontally, said first and second rotary support means dividing each of said at least one first drum and at least one second drum into mutually contiguous regions, on each of which a first awning and a second awning are wound alternately for at least one of said at least one first drum or at least one second drum, said awnings being guided on at least one first bar and at least one second bar, which are mutually adjacent and arranged on the same side of said at least one first drum and at least one second drum, partially surmounting each other laterally.
  • an awning roll-up device characterized in that it comprises a frame provided with first and second rotary support means for at least one first drum and at least one second drum, which are arranged so as to approximately face each other horizontally, said first and second rotary support means dividing each one said at least one first drum and at least one second drum into mutually contiguous regions, on each of which a first awning and a second awning is wound alternately for said at least one first drum and at least one second drum, said first awning being guided on at least one first bar, which is arranged approximately parallel to said second drum, on the opposite side with respect to said first drum, and said second awning descending directly when it unrolls from said second drum.
  • the reference numeral 1 designates two embodiments of an awning roll-up device, each of which comprises a frame 2 constituted by a front element 3, which is obtained advantageously by extrusion, is preferably but not necessarily made of aluminum and has an approximately rectangular transverse cross-section.
  • each wing 4 protrude from a same side of the front element 3; each wing has a C-shaped cross-section, so that each one forms first longitudinal guides 5, which advantageously have an approximately T-shaped transverse cross-section, so as to form a first access opening 6 and two first longitudinal abutments, designated by the reference numerals 7a and 7b, which affect the first guides 5 along their entire length.
  • Two cross-members respectively designated by the reference numerals 8a and 8b, protrude at right angles at least proximate to the lateral ends of the front element 3, are preferably shaped approximately like a parallelepiped, and are fixed preferably to the front element 3 by means of suitable screws or rivets, not shown in the accompanying figures.
  • the first and second drums may have an identical or different longitudinal extension, as long as they lie, starting from the first ends, longitudinally and oppositely until their respective second ends at least mutually overlap.
  • the longitudinal central axis of the second drum 10, arranged closer to the front element 3, is arranged at a lower height than the plane of arrangement of the longitudinal central axis of the first drum 9.
  • One or more first and second rotary support means for the second ends of said at least one first drum 9 and at least one second drum 10, are associated or associable with the frame 2.
  • Said first and second means are advantageously constituted respectively by one or more members 11a and 11b, which are shaped approximately like an inverted letter U, from a first prong 12 of which teeth 13 protrude which are shaped complementarily to the first guides 5.
  • each U-shaped member is followed by a base 14, which protrudes opposite the front element 3, and by a second prong 15, from the end of which first and second arms, respectively designated by the reference numerals 16 and 16', protrude toward the front element 3, said arms being adapted to support rotatably the first drum 9 and the second drum 10 and being advantageously shorter than the base 14.
  • the U-shaped members 11a and 11b can therefore be fixed to the front element 3 by arranging the teeth 13 in the first guides 5 and/or by fixing suitable screws or rivets, not shown in the accompanying figures.
  • At least one first support 17 protrudes from the first arm 16 of the U-shaped member 11 a, approximately at right angles thereto and toward the base 14, and is provided with at least one first hole 18, which accommodates the second ends of the first drum 9 or the first drum 9.
  • the second rotary support means for the second ends of the second drum 10 or for the second drum 10 are similar to said first means, except for the fact that the second arm 16' is longer than the first arm 16 and a second support 19 protrudes therefrom and is provided with a second hole 20, which accommodates said second ends of the second drum 10 or the second drum 10.
  • the first and second supports and the corresponding first and second holes formed therein are respectively aligned axially with the receptacles formed on the cross-members 8a and 8b.
  • first and second drums have approximately the same length; further, the cross-members 8a and 8b may be replaced with a pair of first supports 18 and second supports 19.
  • one or more U-shaped members 11a and 11b are used which are provided with the first and second supports 17 and 19 arranged in intermediate regions, or with the chosen spacing, of said first and second drums.
  • three U-shaped members 11a are associated on the first drum 9 and are provided with first supports 17, which devide the first drum 9 into various mutually contiguous regions, on each of which a first awning 21 is wound alternatively (and therefore in one region but not in the adjacent one).
  • the second drum 10 is supported rotatably by three other U-shaped members 11b, provided with the second supports 19, arranged advantageously in a region adjacent to the first support 17 for the first drum 9.
  • the arrangement of the U-shaped members 11b and of the cross-members 8a and 8b is such that at least one U-shaped member 11b (and therefore a second support 19) is interposed between the first two supports 17 of the first drum 9 with which the first awning 21 is associated.
  • At least one second awning 22 can be wound onto the second drum 10; in the embodiment shown in Figures 1, 2 and 3, it is possible to wind, merely by way of example, two second awnings 23 onto the second drum 10.
  • Each first awning 21 is thus at least partially superimposed laterally on each contiguous second awning 22.
  • the portions of the at least one first awning 21 and of the at least one second awning 22 that unwind respectively from the first drum 9 and from the second drum 10 are then made to pass slidingly at at least one first bar 23 and at least one second bar 24, which are parallel to each other adjacent to the front element 3 and are adapted to keep the portions of the first and second awnings approximately parallel to each other and at a chosen mutual distance once they have been lowered vertically.
  • the first and second bars are at least slightly longer than the respective first or second awnings that affect them.
  • the first and second bars preferably have an approximately rectangular transverse cross-section, in which the transverse ends are conveniently rounded in order to allow the sliding thereon respectively of the portions of the first awnings 21 and of the second awnings 22.
  • the first and second bars are arranged inverted with respect to each other.
  • a second longitudinal guide 25a and a third longitudinal guide 25b are formed on the two lateral surfaces of the first and second bars, asymmetrically with respect to the central transverse axis, and are mutually mirror-symmetrical with respect to a central plane arranged longitudinally to the first and second bars.
  • the second guide 25a and the third guide 25b have an approximately T-shaped transverse cross-section, so as to form respectively a second access opening and a third access opening and second and third longitudinal abutments, which affect respectively the second and third guides 25a and 25b, along their entire length.
  • the first bar 23 is associable, at its ends, with the facing lateral surface of the front element 3 by means of two first brackets, designated respectively by the reference numerals 26a and 26b, which are approximately I-shaped and whose ends can be inserted in the first guide 5 of the front element 3 and in the third guide 25b of the first bar 23.
  • the second bar 24 is associable with the adjacent first bar 23 by means of two second brackets, designated respectively by the reference numerals 27a and 27b, which are approximately I-shaped and whose ends can be inserted respectively in the second guide 25a of the first bar 23 and in the second guide 25a of the second bar 24.
  • the length of the pairs of first and second brackets can change depending on specific requirements; the user can thus preset or change the mutual distance between the first and second awnings.
  • the adjustability of the position of the first brackets 26a and 26b with respect to the front element 3 and of the second brackets 27a and 27b with respect to the first brackets 26a and 26b allows the user to preset or change the extent of the overlap of the first and second awnings.
  • the awning roll-up device 1 can lack the second bars 24 and can comprise therefore only one or more first bars 23: in this case, only the portions of the awnings 21 that unwind from the first drum 9 are then made to pass slidingly at at least one first bar 23, while the second awning or awnings 22 descends or descend directly, as it unwinds or they unwind from the respective second drum 10, without the aid of any intermediate element (see Figure 13).
  • the first bar 23 is arranged approximately parallel to the second drum 10, on the opposite side with respect to the first drum 9, and is adapted to keep said portions of the first awning 21, once they have been lowered vertically, at a chosen distance from the front element 3.
  • the device 1 is fixed in an upper region with respect to a space to be covered with an awning; the first drum 9 and the second drum 10 can be turned by way of suitable known movement means, such as for example electric motors or a suitable and known manually-operated chain, which are not shown in the accompanying figures.
  • suitable known movement means such as for example electric motors or a suitable and known manually-operated chain, which are not shown in the accompanying figures.
  • the first awning or awnings 21 and the second awning or awnings 23 are then made to descend vertically, sliding respectively on the first bar 23 and on the second bar 24; they are thus kept approximately parallel to each other and at a chosen mutual distance.
  • the device 1 does not comprise the second bars 24 but comprises only the first bars 23, the first awning or awnings 21 is or are conveyed, along an inclined plane, on the respective first bar 23, in order to be made to descend vertically, while the second awning or awnings 22 descends or descend directly, as they unwind from the respective second drum 10, without the aid of any intermediate element (see Figure 13).
  • each of the first awnings 21 is further partially superimposed laterally with respect to the contiguous second awnings 22, achieving the complete coverage of the space without any discontinuity in a horizontal direction.
  • an awning roll-up device having been devised which is capable of completely covering the opening even of a space that has a considerable horizontal extension.
  • first and second supporting means it is possible to use drums that have a small diameter without subjecting them to intense flexing.
  • the production costs of the device according to the invention remain low, since such device is constituted by components that are easily available or simple to manufacture and assemble.
  • Figures 4, 10, 15 and 16 illustrate two additional embodiments of awning roll-up devices 101, each of which comprises a frame 102 constituted by a box-like body 128, which is advantageously approximately shaped like a parallelepiped and is hollow and is extended longitudinally in a horizontal direction.
  • the substantially flat bottom 129 is associable detachably with the box-like body 128; the longitudinal ends 132a and 132b of the bottom 129 are slidingly associable with complementarily shaped seats 133 and 134 formed at the lower ends of a front wall 130 and of a rear wall 131, which constitute the box-like body 128.
  • One or more first and second rotary support means are associated or associable with the frame 102 of the device 101 and support at least one first drum 109 and at least one second drum 110, which are arranged approximately parallel to each other on a plane which is preferably horizontal or slightly inclined with respect to the perpendicular to the front wall 130.
  • first and second drums may have an identical or different longitudinal extension, as long as they are arranged longitudinally, starting from the first ends, oppositely with respect to each other until the respective second ends thereof at least mutually overlap.

  • the first and second rotary support means are constituted advantageously respectively by at least two third supports 135 and at least two fourth supports 136, which protrude approximately at right angles from the bottom 129 of the box-like body 128 and are provided respectively with a third hole 137 and a fourth hole 138, which accommodate respectively the first drum 109 and the second drum 110 or their ends.
  • the third supports 135 and the fourth supports 136 can be arranged in a chosen longitudinal position with respect to the first drum 109 and the second drum 110; at least one fourth support 136 of the second drum 110 is interposed in any case between two third supports 135 of the first drum 109.
  • first supports 135 and the second supports 136 optionally located at the ends of said first and second drums can be constituted advantageously by a single body, in which the third and fourth holes are provided respectively.
  • first and second drums In order to support appropriately the first and second drums, if they have a chosen length, and in order to avoid their flexing, one or more third and fourth supports arranged in intermediate regions or at the chosen spacing, of the first and second drums, are used.
  • three first supports 135 are associated with the first drum 109: two are arranged at the ends of the drum and are formed monolithically respectively with two fourth supports 136, and one is arranged approximately at the centerline of the drum 109; the third supports 135 divide said drum into two mutually contiguous regions, on each of which two first awnings 121 are wound along part of the length.
  • the second drum 110 is supported rotatably by four second supports 136: two are arranged at the ends of the second drum 110 and are formed monolithically respectively with two first supports 135 located at the ends of the first drum 109, and two are interposed respectively between said supports and the third support 135 arranged approximately at the centerline of the first drum 109.
