Definitions

• the present invention relates to a device used for deploying the fabric of an awning.
• An awning consists of a fabric that can be unrolled over a more or less extensive area to protect oneself from the sun or inclement weather.
• An awning uses a complete deployment system to unroll or roll up the fabric.
• the deployment system typically consists of a fixed frame designed to be mounted on a building wall. This frame supports a roller onto which the fabric is wound, and a motor that drives the roller to wind or unwind the fabric.
• the system also includes a sliding weight bar that pulls the fabric when it is unfurled.
• the system generally incorporates two deployment mechanisms arranged in parallel, which drive the weight bar and tension the fabric when it is fully unfurled.
• Each deployment device includes an arm having a first fixed end connected to the chassis by an articulated link and a second mobile end connected to the load bar by another articulated link.
• the arm Between its first and second ends, the arm extends lengthwise by means of a first element and a second element connected by a central hinge, allowing it to pivot relative to each other between a folded and unfolded position.
• the arm is in its folded position when the fabric is rolled up and unfolds progressively as the fabric is unrolled.
• the device To move the arm from its folded to its unfolded position, the device includes a pre-stressed tensioning system designed to store elastic energy, enabling the arm to unfold from its folded to its unfolded position.
• This tensioning system includes a tension link (cable, chain, or other) to which pre-stressed elastic elements are attached.
• the device may include a sheath arranged at the joint to pass the tension link (the cable) along the arm.
• This sheath is made of a flexible material so that it deforms when the arm is bent or unbent.
• the electrical cable is integrated into at least one of the arms of the two deployment devices.
• this integration is often unsatisfactory from both a functional and aesthetic point of view, particularly at the central articulated joint of the arm.
• the aim of the invention is to propose a deployment device in which the integration of an electrical connection is satisfactory, from a functional and aesthetic point of view.
• the tension link consists of a cable, a ribbon, or a chain.
• the tension link is a cable, the cable having a first fixing end forming a loop so as to form two distinct strands passing respectively through said first conduit and a third conduit (41) of the sheath, each strand having a free end on which is hung a spring of said elastic means.
• the first conduit, the second conduit and the third conduit are each made in the sheath in a longitudinal direction when the arm is in the unfolded position.
• the first, second, and third conduits are arranged with their longitudinal direction lying in the same plane.
• the device includes means for retaining the sheath in position on said arm.
• Another distinctive feature is that the electrical connection includes several wires. Another distinctive feature is that the sheath contains several other conduits for other electrical connections.
• the device includes means for retaining the tension link on said arm.
• the first element includes an external housing with a longitudinal tube adapted to carry the electrical connection, upstream of the sheath.
• the invention applies to a device used for deploying the fabric of an awning.
• the invention relates more particularly to the architecture of such a device used for deploying the web.
• Each device therefore comprises an arm 1 having a first end 100 intended to be fixed to the fixed frame and a second end 110 intended to be fixed to the load bar.
• the arm 1 consists of a first element 10 intended to be fixed to the fixed frame by the first end of the arm and a second element 11 intended to be fixed to the load bar.
• the two elements 10 and 11 cooperate to form a hinged joint 12, arranged to allow the arm 1 to pivot between its two positions.
• the arm is also pivotally mounted at both ends: its first end 100, fixed to the fixed frame, and its second end 110, mounted to the load bar.
• the pivots are advantageously arranged along directions transverse to the plane of the canvas. They are not necessarily perpendicular to this plane. When extended, the arm may move away from the canvas.
• the central articulated link 12 of the arm 1 Thanks to the central articulated link 12 of the arm 1, the first element 10 and the second element 11 of the arm are able to pivot relative to each other.
• the first element each includes an external housing 101 (for the first element), 111 (for the second element) forming an external fairing, for example in aluminium, enclosing the mechanism of each element of the arm and fitting onto the articulated link.
• the device also includes a pivoting actuation mechanism for the arm between its two positions.
• the arm When in its unfolded position, the arm can form a V between its two elements, as the axes of the different articulated links are not necessarily parallel to each other.
• the arm 1 actuation mechanism includes a tension assembly designed to mechanically move arm 1 to its extended position, thus tensioning the fabric.
• the system reverses the tension assembly to fold each arm 1.
• This tension assembly of the device advantageously includes at least one tension link.
• this tension link is a cable 2.
• Some solutions use several cables in parallel and are perfectly adaptable to the device of the invention. Similarly, it would also be possible to replace each cable with another type of link, for example, a chain, a ribbon, or equivalent.
• the cable 2 used in the device is divided into two separate strands 20, 21 by forming a loop 22.
• This loop 22 forms a first attachment end of the cable 2.
• the two strands 20, 21 formed by the loop each terminate in a free end 200, 210 onto which a spring 300, 310 is attached.
• Each spring is pre-stressed when the arm is folded so that it can move the arm 1 towards its unfolded position.
• the two springs 300, 310 can have different spring constants to manage the dynamics of the arm's deployment.
• the tension assembly is attached via each spring 300, 310 to the first end 100 of the arm 1, located on the side of the fixed chassis and via the loop 22 formed by the cable 2 to the second end of the arm.
• the tension assembly extends at least over part of the first element 10 of the arm 1, continues through the articulated link 12 between the two arms, and then, at least in part, along the second element 11 of the arm 1.
• the device comprises a sheath 4 through which the two strands 20, 21 of the cable pass.
• the sheath 4 is made of a material chosen to be sufficiently flexible to deform at the articulated joint 12 when the arm 1 is folded. This could be a rubber-type material or equivalent.
• the two strands 20, 21 pass through the sheath 4 in parallel.
• the sheath 4 is equipped advantageously of two first longitudinal conduits 40, 41, each traversed by a strand 20, 21 distinct from the cable.
• the device may include means for retaining the sheath in position within each arm element, so as to remain in place during arm pivoting.
• retaining means include, for example, locking sleeves 42 positioned at the outlet of each conduit 40, 41 of the sheath 4, each designed to cooperate with a housing on the body of the element.
• the device may also include, on each strand 20, 21 of the cable, on the side of its fixing loop 22, a retaining sleeve 23 for the cable in the second element.
• the cable 2 thus remains in place during the pivoting of the arm 1, its variation in length being absorbed by the springs.
• the sheath 4 comprises at least one other longitudinal conduit 43 through which an electrical connection 5 is inserted.
• the electrical connection 5 may comprise several separate electrical wires 50, 51 grouped within a single cable or several cables passing through the same dedicated longitudinal conduit 43 of the sheath. It would also be possible to provide a separate longitudinal conduit within the sheath 4 for each electrical connection.
• the sheath 4 is positioned so as to pass over the outside of the articulated joint 12 of the arm. It thus follows the external curvature of the articulated joint 12 when the arm is pivoted into its folded position.
• the electrical connection 5 is lengthened upstream or downstream of the sheath 4, so as to maintain slack 52 ( figure 4B ), thus allowing the pivoting movement of arm 1 to be followed without damage and without traction likely to damage the installation.
• the three longitudinal conduits are arranged superimposed along the same plane P, perpendicular to the plane of the fabric.
• the longitudinal conduit 43 dedicated to the passage of the electrical connection 5, is positioned between the two other longitudinal conduits 40, 41, each dedicated to the passage of a separate strand 20, 21 of the cable 2.
• conduit By conduit, we must understand an independent channel having a closed cross-section and extending over a length sufficient to longitudinally accommodate one or more wires of the electrical connection.
• Sheath 4 also provides additional protection for the electrical connection.
• the external housing 101 of the first element 10 may also include an internal longitudinal tube 102, closed by a plastic strip 103, pierced, for example, with one or more holes 104 to allow the electrical connection 5 to pass into the tube 102, at the outlet of the sheath 4.
• the figure 4C This demonstrates the specific architecture.
• the electrical connection 5 is thus isolated, both electrically and mechanically, from the springs 300 and 310 along the first element 10 of the arm.
• This tube 102 accommodates the electrical connection upstream of the sheath 4, the latter being dedicated to the passage of the electrical connection at the level of the articulated joint 12.
