Definitions

  • the present invention relates to retractable awnings or like sunprotection window coverings.
  • retractable awnings a fabric or cloth sheet material is rolled or unrolled onto or from a roller and a forward end of the fabric. wich is attached to a movable front bar, is guided and supported by a pair of collapsible arms.
  • the collapsible arms together with the front bar define a collapsible frame, which is supported by the same structure that also supports the roller.
  • Such retractable and extendable awnings are generally known and usually comprise biasing means acting on the collapsible frame to urge the awning sheet and frame towards the extended position.
  • Suitable arrangements for biasing awning arms into an extended position are described a.o in GB 1.175.723; EP 0,125,727, EP 0.489.186 and EP 0.795.660.
  • these documents show the arrangement of tension springs and the use of different forms of flexible elements. such as cables: chains and flexible belts or strips.
  • One problem associated with such arrangements is that the required length of spring extension or compression, to act during the full movement of such arms, is rather large.
  • Another problem associated with such arrangements is that the flexible elements are deflected through angles and around radii, which tend to be rather small in relation to their required size. This and the rather high tension forces involved tends to reduce the durability of these flexible elements.
  • the present invention overcome or ameliorate at least one of the disadvantages of the prior art. It is also an object of the present invention to provide alternative structures which are less cumbersome in assembly and operation and which moreover can be made relatively inexpensively.
  • the present invention thus has as an object to eliminate inconveniences of the prior art by providing such an awning with improved features.
  • an articulated awning support arm for a retractable and extendable awning
  • the articulated arm including: an elongate first pivoting arm section; an elongate second pivoting arm section, a central hinge defining a pivot axis generally perpendicular to the longitudinal extent of at least one of the first and second arm sections, the central hing being arranged to pivotally connect the first arm section to the second arm section; at least one resilient element associated with one of the first and second arm sections for pivotally biasing the other of the first and second arm sections towards the one arm section associated with the at least one resilient member; and a swivel element associated with the central hinge, so as to share the pivot axis of the central hinge the swivel element having a first outrigger and a second outrigger angularly spaced from the first outrigger: wherein one end of the at least one resilient member is connected in a force transmitting manner to the one arm section, with which it is associated, the other end of the at least one resilient member
  • the invention also provides a retractable and extendable awning.
  • a retractable and extendable awning including at least one arm support bracket. incorporating at least one articulated awning support arm in accordance with the invention, a front bar, a roller adapted to be mounted for rotation, a fabric cloth for winding about and unwinding from the roller, wherein the first arm section has a first end pivotally linked to the bearing support and a second end, the second arm section having a first end pivotally linked to the second end of the first arm section and a second end pivotally linked to the front bar.
  • FIG. 1 shows a retractable arm awning 1 of the general type with which the present invention is concerned.
  • the awning 1 of Figure 1 has a wall mount cassette 3 housing a roller 5 from which a fabric cloth 7 in the extended position of the awning is extending and supported by a collapsible support system comprising a front bar 9 connected to a front edge of the fabric cloth 7 and two collapsible arms 11, 13.
  • Each of the collapsible arms 11, 13 is hingeably mounted from a corresponding arm support bracket 15 and 17 respectively and comprises first and second pivoting arm sections 19, 23 and 21, 25 respectively.
  • Each of the first and second arm sections are joined by a central pivot joint 27, 29 respectively and the second arm sections 21, 25 are hingeably joined to the rear side of the front bar 9.
  • the front bar 9 preferably. but not necessarily, is shaped as a lid to close the opening 31 in the cassette 3 from which the fabric cloth and collapsible frame extend, when the awning is in a retracted position.
  • the awning of Figure 1 preferably includes some mechanism for adjusting the angle 33 at which the awning extends from a building wall (not shown).
  • Figure 2 shows a perspective view of a collapsible awning arm corresponding to awning arm 13 of Figure 1.
  • Arm 13 has a first pivoting section 23 and a second pivoting section 25.
  • the first and second pivoting sections are joined to one another by a central pivot joint 29 and a front pivot 89 connects the front bar 9 (shown in Figure 1) to an opposite end of the second pivoting section 25.
  • first arm section 23 opposite of the central pivot swivel 29 carries a forked end 93 for hingeably attaching to the arm support bracket 17 (shown in Figure 1).
  • a hinge pin (not shown, but conventional) will be inserted through respective openings 95, 96 in an aligned arrangement with a through bore of the arm support bracket 17(of Figure 1).
  • the first and second arm sections 23, 25 each comprise a length of tubular profile 97. 99 respectively, which can each be of an appropriate length in relation to the desired drop of the awning and the extended length of the awning cloth (7 in Figure 1).
  • the forked end 93 is in the form of a first end plug element 101, which partly engages into the hollow interior of the tubular profile 97
  • the central pivot joint 29 is an assembly of second and third plug elements 103, 105
  • the front pivot 89 is arranged on yet another, fourth plug element 107.
  • Figure 3 the awning arm of Figure 2. but with the tubular profiles 97 and 99 removed to show the internal structure of the collapsible awning arm 13
  • Figure 3 clearly shows a first spring 151 and a second spring 153. These are tensioning springs and As shown in Figure 3. are in a relaxed position.
  • One end 155 of the first spring is attached to a first link 157. while another end 159 of the first spring 151 receives a screw 161.
  • the screw 161 is rotatably held in the first end plug 101 and can be rotated from the exterior of the first end plug 101 for increasing or reducing the tension of the first spring 151.
  • the second spring 153 has one of its ends connected to a second link 163. which extends fro the central pivot joint 29 in a direction opposite to the first link 157.
  • the other end of the second spring element 153 can either be fixedly attached to the fourth end plug 107 by a screw 165 or be adjustable as described in relation to the first end plug 101.
  • one or more of the spring ends can receive a resilient end cap 167 to inhibit noise production of the spring end if scraping against an inner wall surface of tubular profiles 97 and 99 when fitted as shown in Figure 2.
