Definitions

  • the present invention relates to retractable awnings or like sun protection 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, which is attached to a movable front bar, is guided and supported by a pair of articulated and collapsible arms.
  • the articulated arms together with the front bar define a collapsible frame, which is supported by the same structure that also supports the roller.
  • the articulated arms usually comprise two hollow arm profile parts that are hingedly connected by a central swivel pivot. End plugs co-operating with the hollow interior of the arm profiles serve to attach functional outer portions to the arms.
  • This invention further relates to an articulated arm for an awning and specifically to an end plug element for the arm.
  • End plug elements of articulated arms for awnings are known from DE 42 00 564, EP 1,063,367 and EP 1,122,378.
  • All end plug elements comprise two portions, an outer portion and a plug-in portion.
  • the outer portion of the end plug comprises a functional part for co-operation with a support bracket for hingedty connecting the arm to the bracket, or for attaching the arm to the front bar, or for forming a central swivel pivot in order to make the arm an articulated arm.
  • the plug-in part co-operates with the hollow interior of the arm profile. There are different known methods of attaching the end plug elements to hollow interior of the arm profile.
  • the wedge is adjustable in longitudinal direction of the arm, which makes it impossible to adjust without disassembling the hinge pivot and or without taking the arm away from the mounting bracket or the front bar. This makes on-site repairs difficult and cumbersome. And it also precludes relative simple adjusting of the plug, once the awning is assembled.
  • the plug travels along a threaded bolt into clamping position, but in this case the bolt can become loose and fall out or stick out.
  • the position of the wedge and bolt might weaken the connecting web between the outer functional part of the end plug element and the plug-in part, since a hole has been provided in the web for passage of the bolt which pulls the wedge into position.
  • the present invention has as an object to eliminate inconveniences of the prior art by providing such an end plug with improved features.
  • the invention provides an arm for an awning comprising a tubular arm profile and an end plug element inserted therein and fixedly attached therewith, wherein the tubular arm profile is of generally rectangular cross-section with a hollow interior and front, back, top and bottom walls each comprising an inner surface, the end plug element comprises a body portion and a wedge which together co-operate with at least one of the walls of the hollow interior of the arm profile once inserted therein, wherein the body portion comprises an upper support wall which comprises a sloped portion which is in contact with a sloping bottom wall of the wedge, the wedge further comprising a top wall which is in contact with the top wall of the arm profile and front and back walls connecting the top and bottom walls and wherein the wedge is positionable laterally along the upper support wall from the outside of the arm profile.
  • FIG. 1 shows a retractable arm awning 1 with articulated arms of the general type with which the present invention is concerned.
  • the awning 1 of Figure 1 has a wall mounted cassette 3 housing a roller 5 with a fabric cloth 7 attached to the roller with a rear edge of the fabric, a front bar 9 connected to a front edge of the fabric cloth 7 and a left and right articulated collapsible arms 11, 13 one end of which is attached to the wall and another end is attached to the front bar.

  • the end plug according to the invention can have any type of outer part, a forked part or a hinge body or another type of functional outer part suitable for attaching the arm to a mounting bracket, forming the central swivel pivot or for attaching the arm to the front bar.
  • the end plug element 37 comprises outer part 39 and plug-in part 41.
  • the plug-in part 41 extends in longitudinal direction from a back web 40 of the outer part 39 and can be longitudinally inserted in the hollow interior 67 of the arm profile 15.
  • the arm profile 15 is a hollow tubular profile which is generally rectangular. Having a longitudinally extending upright back wall 69, an opposite longitudinally extending upright front wall 71. the back and front walls 69, 71 being connected by longitudinally extending lateral top and bottom walls 73, 75.
  • the inner surface of the bottom wall 75 comprises a ramp 77 which laterally extends from the bottom near the back wall 69 towards the front.
  • the ramp 77 has a sloped top 79 which increases in height as it extends laterally towards the front and preferably reaches its maximum height near the lateral middle of the bottom.
  • the ramp 79 than ends in a generally steeply downwardly sloping or vertical wall 81, extending generally parallel to the inner surface of the upright front wall 71.
  • the ramp 77 extends in longitudinal direction along the inner surface of the bottom wall 75 of the arm profile 15.
  • the inner surface of the front upright wall 71 comprises a ridge-like portion 83. It extends a small distance laterally inward from the top of the inner surface of the front upright wall towards the upright back wall 69 and comprises an upright inner surface 85 facing the inner surface of the upright back wall 69 and being generally parallel thereto.
  • the ridge 83 ends in a lateral lower surface 87.
  • the ridge 83 extends in longitudinal direction along the inner surface of the front wall 71 of the arm profile 15, and serves as a thickened portion of the front wall 71 of the arm profile 15.
  • the plug-in part 41 of end plug element 37 comprises a body 89 and a wedge 107
  • the body 89 extends in longitudinal direction from a lateral upright back web 40 of the outer part 39 of the end plug element and is formed to fit into the hollow interior 67 of the arm profile 15.
  • the body 89 comprises an upright longitudinally extending back wall 91 and two spaced apart upper and lower support walls 93 and 95 extending laterally inward from the back wall
  • the support walls 93 and 95 can be separated from each other by a generally U-shaped open channel 97. as is shown in figure 3.
  • Upper support wall 93 has a narrow lateral extending horizontal portion 99. It further comprises an inward and downward sloping portion 101.
  • the lower support wall 95 has a narrow lateral extending horizontal portion 103, it also has an inward and upward sloping portion 105.
  • the end-plug element 37 When the end-plug element 37 is inserted into the hollow interior of the arm profile 15, horizontal portion 99 of the upper support wall 93 will be in contact with a portion of the inner surface of the top wall 73 and the sloping portion 101 of the upper support wail 93 will carry the wedge 107. Furthermore the horizontal portion 103 of the lower support wall 95 will be in contact with a narrow horizontal portion of the inner surface of the bottom wall 75 between the upright back wall 67 and the ramp 77, and the sloping portion 105 of the lower support wall 95 will rest on the ramp surface 79. The sloping portion 105 of the lower support wall 95 is complementary in slope to the slope of the ramp surface 79.
  • the lower support wall of the body 89 comprises a wide horizontal portion and not a sloping portion. The wide horizontal portion will contact the inner surface of the bottom wall of the profile, which in this case will not have a ramp.
  • the wedge 107 is a longitudinally extending generally triangular part. it comprises an upright longitudinally extending back wall 109, an upright, longitudinally extending front wall 111, a top wall 113 extending laterally between back and front wall and connecting the two.
  • the back wall 109 has a smaller height than the front wall 111, and a sloping wall portion 115 connects the lower portions of the back 109 and front walls 111.
  • the sloping wall portion 115 slopes in a lateral direction upward from front to back.
  • the sloping wall 115 of the wedge is complementary in slope to the sloping wall portion 101 of the upper support wall 93.
  • the wedge 107 also has the same longitudinal length as the upper support wall 93 of the body 89 of the plug-in part 41 of the end plug element 37
  • a threaded bore 117 extends honzontally in a lateral direction from upright front wall 111 through the wedge 107 end exits in the sloping wall portion 115.
  • the sloping portion 101 of the upper support wall 93 of the body 89 of the end plug element comprises a blind hole or recess 119 ending in an generally vertical wall portion 121.
  • the front wall 71 of the arm profile 15 has a through hole 123 in the ridge 83.
  • a flat ended bolt 125 with a head 127 and a screw threaded stem 129 can be screwed in the bore 117.
  • the head 127 of the bolt 125 comprises an inner surface 131 oriented towards the stem 129 and a planar outer surface 133 oriented away from the stem.
  • the bolt when assembled to the wedge will extend through the bore 117 into blind hole or recess 119 of the body 89 of end plug element 37, the end of the stem abutting or almost abutting against vertical wall portion 121 of the blind hole.
  • the two parts 89 and 107 of the end plug are thus pre-assembled and can be inserted into the hollow interior 67 of the arm profile 15. Once inserted, the three holes 117, 119 and 123, and the bolt are aligned.
  • the outer surface 133 of the head 127 of the bolt 125 bolt abuts against the a portion of upright inner surface 85 of ridge 83.
  • the bolt head is effectively captured between the wedge and the front wall of the profile.
  • the bolt head 127 comprises a slot or a hexagonal blind hole for co-operation with the end of a screw-driver or a hexagonal tool, and can be reached by such tools through hole 123 in the profile.
  • the wedge will travel upward along the sloped portion 101 of the upper support wall 93 and will securely wedge the end plug element 37 in the hollow arm profile 15. If the bolt is turned in the opposite direction, the wedge will travel along the screw thread in the reverse direction, and loosen the connection between plug end element 37 and the profile 15.
  • Figure 4 shows a cross section of an assembled plug-in part of an end plug element in a arm profile.
  • top wall 113 of wedge 107 is forced against the inner surface of top wall 73 of the arm profile 15.
  • the wedge is also forced against sloping wall portion 101 of upper support wall 93.
  • the wedging forces are thus also directed through body 89 towards back wall 69 of arm profile 15.
  • sloping wall portion 105 of lower support wall 95 is forced against upper surface 79 of ramp 77. This also results in a wedging force directed towards back wall 69 of the arm profile 15.
  • the wedge provides for the wedging forces acting on the upper, lower and back walls of the arm profile firmly securing the end-plug element in the arm profile.
  • plug-in part of the end plug element is described and shown in the figures as end plug element 37 of the articulated arm. All end plug elements used in the arms of any awning can have a plug-in part comprising a body and a wedge as described above.
  • the plug-in element and the wedge can be made longer in longitudinal direction. Additional screw-hole and bolts can be spaced apart along the length of the wedge and the arm profile. Since the wedge extends along the length of the body it has a maximum effective surface. The lateral travel up against the sloping wall portion is relatively small without decreasing the effective wedging force. The head of the bolt is of a larger diameter than the hole in the front wall on the profile. And the dimensions are chosen so that the bolt can travel in vertical direction as the wedge travels upwards against the sloping wall portion.
  • a U-shaped ridge 140 can be placed such that a spring end can be attached to it. So that springs used in conventional retractable and extendable awnings as biasing means acting on the articulated arms to build the collapsible frame can be attached to the end plug elements where required. Or other arrangements such as different forms of flexible elements, such as cables; chains and flexible belts or strips. Of course other attachement means are possible, doing away with the U-shaped channel altogether. The way of attaching springs or other biassing means to the end plug elements does not change the plug-in part according to the invention.
