Definitions

  • the invention relates to an electric actuator chain for an opening such as a gate leaf.
  • an electromechanical actuator between a pillar and a leaf, in particular to allow remote opening before the arrival of the vehicle in front of the gate.
  • an actuator for operating a gate leaf comprising, as means of transmitting motion, an open chain.
  • open-chain actuators or push-pull
  • a particular problem concerns the immobilization of an opening, such as a gate leaf, in the pushed configuration of the chain.
  • a door leaf must be able to withstand wind, shocks or attempts to maneuver forced by hand.
  • the electric motors used in known actuators generally do not have sufficient irreversibility to withstand such efforts.
  • the addition of a gearbox or a brake which allow this irreversibility with other transmission means that an open chain, such as a wheel and worm device, would significantly increase the price of returns from such an actuator, without necessarily being compatible with the open chain transmission.
  • the invention more particularly intends to remedy by proposing a new electric chain actuator for opening, in particular for gate leaf, which reliably and economically ensures an irreversibility function.
  • the invention relates to an electric actuator chain for opening, this actuator being intended to be supported by a fixed plate and comprising an electric motor driving a pinion, a carriage movable along a predetermined path, between a first position and a second position, this carriage being kinematically linked to the opening, an open chain engaged with the pinion and hinged to the carriage, and a core on which is mounted the engine and which defines an elongated housing for guiding the chain and of the carriage, this housing comprising, at one end, a receiving area of the carriage in its first position.
  • the housing is bordered by, and opens into, a partial receiving cavity of at least two links of the chain in a locking configuration where respective longitudinal axes of these links form between them an angle greater than 45 °, while the carriage is in place in the receiving zone.
  • the at least two links are able to be engaged in the cavity by a pushing force exerted on a tab integral with the carriage and directed towards an axis of rotation of the pinion, whereas, when engaged in the cavity, these at least two links block a movement of the leg and the carriage towards the pinion.
  • the cavity which borders the housing in which the chain moves can receive two links in a configuration where they are misaligned, to the point that they form with the edges of this cavity a stop to a movement tending to push the carriage outside the reception area, that is to say to release it from its first position.
  • the two links of the chain received in the cavity constitute with it irreversibility means that maintain the carriage in its first position, without soliciting the electric motor nor require a brake
  • a leaf 2 is articulated on a pole 4 about an axis X2 which is vertical and delimited by hinges 22 and 24.
  • a plate 6 is fixed on the pole 4 and supports an electric actuator 8 which is articulated on this plate around an axis X8 parallel to the axis X2.
  • a tab 10 is fixed on the leaf 2 by means of two screws 12 represented by their centerlines at the figure 1 .
  • two screws 12 represented by their centerlines at the figure 1 .
  • the base of the tab 10 is shown on the drawing. figure 2 and this leg is omitted on the Figures 3 to 5 .
  • the tab 10 is secured to a carriage 82 which belongs to the actuator 8 and which is attached to an end 84A of an open chain 84.
  • a part of the tab 10 is shown in solid lines in a first position, on the right of this figure, and in phantom in a second position, on the left of this figure.
  • the part of the motor 8 which is used for its mounting on the plate 6 is omitted in this figure, as well as the outer cover 81 of the motor 8 which is visible to the figure 1 .
  • 841 is a first link of the chain 84 which is articulated on a shaft or pin 821 of the carriage 82 and which constitutes the end 84A.
  • 842 is a second link of the chain 84 which is articulated on the link 841 around a shaft 843.
  • the actuator 8 also comprises an electric motor 86 which is mounted cantilevered on a core 88 made by cutting a sheet metal plate and in which are defined two sliding recesses L1 and L2 of the chain 84 respectively according to two directions D1 and D2 which, in the example shown, are parallel to a longitudinal axis A88 of the core 88.
  • the core 88 may be formed by the stack of several sheets, for example three.
  • the motor 86 is shown in phantom at the figure 2 because it is behind the soul 88 with respect to the cutting plane. It incorporates a gearbox that forms a bevel gear.
  • the output shaft 861 of the motor 86 drives a pinion 862 which is engaged with the chain 84 shaped in a 180 ° turn around the central axis Y86 of the shaft 861, the axis X86 being perpendicular to the axis A88 and the lateral surfaces of the core 88, including that visible at figure 2 .
  • the carriage 82 can be brought into different positions in the housing L1.
  • a first position represented in solid line at the figure 2 and which is obtained by a rotation of the pinion 862 in the direction of the arrow R1 the carriage 82 is disposed in an end zone Z1 of the housing L1 which corresponds to an end-of-travel configuration for the tab 10 relative to the 88.
  • the carriage 82 and the tab 10 can be brought into the position shown in phantom for the tab 10, this position corresponding to a second end-of-stroke configuration.
  • the carriage 82 is movable in a path defined by the housing L1 between the configuration shown in solid lines to the figures 2 and 3 and that corresponding to the position shown in phantom of the tab 10 on the figure 2 .
  • the displacement between these first and second positions is rectilinear, along the direction D1. Alternatively, it could be curved.
  • the directions D1 and D2 coincide with the respective longitudinal axes of the housings L1 and L2.
  • the housing L1 and L2 through the soul 88 from side to side. 101 and 102 are respectively noted the two longitudinal edges of the housing L1 which extend in the thickness of the web 88.
  • the edge 102 is closer to a longitudinal edge 881 of the web 88 as the edge 101.
  • Each of the edges 101 and 102 is shaped as a rail to be engaged between the plates of the links of the chain 84, which guides the chain 84 in the housing 81 , without this chain being able to slide out of the housing L1, in a direction perpendicular to that of the plane of the Figures 2 to 5 .
  • the two longitudinal edges 103 and 104 of the housing L2 which are defined in the thickness of the core 88 are also each configured in the form of a rail intended to be engaged between the plates of the links of the chain. 84, to guide this chain in the housing L2.
  • the carriage 82 has, in section perpendicular to its direction of sliding in the housing L1, a complementary shape of the edges 101 and 102, which allows it to be guided by these edges.
  • edges 101 to 104 are formed by portions of the core 88 of reduced thickness compared to the nominal thickness of the core, measured at a distance from the housing L1 and L2.
  • the edge 101 is interrupted and the housing L1 opens into a cavity C1 adjacent the housing L1 and which is bordered by a portion 887 of the core 88 which has a thickness, measured perpendicular to the plane of Figures 2 to 5 less than the rest of the core 88.
  • the thickness of the portion 882 is identical to that of the edge 101.
  • a shim 89 is provided in the edge 102, facing the cavity C1. This shim protrudes from the edge 102 towards the cavity C1.
  • the links 841 and 842 arrive in the configuration of the figures 2 and 3 where the longitudinal axis A841 of the link 841, which connects the shafts 821 and 843, forms a non-zero angle ⁇ 1 with the direction D1.
  • the third link 844 is the third link of the chain 84 starting from the carriage 82 and 845 the articulation shaft between the second and third links 842 and 844.
  • A842 is noted the longitudinal axis of the second link, which connects the trees 843 and 845. In the configuration of figures 2 and 3 the axis A842 forms with the direction D1 a second angle ⁇ 2 which is non-zero.
  • each of the angles ⁇ 1 and ⁇ 2 may be of the order of 30 °.
  • the first and second links 841 and 842 are partly driven towards the cavity C1 in which are partially received at their hinge zones around the shaft 843.
  • the axes A841 and A842 form between them an angle ⁇ which is non-zero and, in the example of the figures, equal to the sum of the angles ⁇ 1 and ⁇ 2, ie 60 °.
  • the dimensions of the cavity C1 are selected according to the dimensions of the links of the chain 84 so that the angle ⁇ is greater than or equal to 45 °, preferably greater than or equal to 60 °, so as to ensure misalignment links in the cavity C1.
  • This position of links 841 and 842 in the configuration of figures 2 and 3 results from the geometry of the cavity C1 which is generally triangular in shape with a first open side defining the junction zone between the cavity C1 and the housing L1.
  • This imaginary side is identified by the line in phantom 882 at the figure 4 .
  • the cavity C1 is delimited, in the vicinity of the portion 887, by a first edge 883 and a second edge 884, these two edges being closed, in that they consist of material, unlike the purely geometric edge 882 of the cavity C1 which connects this cavity with the housing L1.
  • Fillet connections connect the edges 883 and 884 to each other and to the edge 101.
  • the cavity C1 is triangular in shape with rounded edges.
  • the edge 882 is parallel to the direction D1.
  • ⁇ 1 the angle formed by the edge 883 and the direction D1 and ⁇ 2 the angle formed by the edge 884 and the same direction D1.
  • the angle ⁇ 1 has a value less than that of the angle ⁇ 2.
  • the angle ⁇ 1 may be of the order of 30 °, while the angle ⁇ 2 is of the order of 60 °. It is indeed advantageous to provide an asymmetrical geometry of the cavity, to allow the realignment of the links when the chain is pulled by the action of the motor and a folding of the links when the chain is pushed in a reverse movement.
  • the first link 841 extends along the substantially rectilinear edge 883, so that the angles ⁇ 1 and ⁇ 1 have identical or substantially identical values.
  • the geometry of the cavity C1 can be provided so that a wedge 885 protruding between the edges 101 and 884 engages between the shafts 843 and 845 in the configuration of the figures 2 and 3 as shown in dashed line at figure 3 .
  • This 885 projecting corner allows a locking of the link along the edge 883 and thus a better irreversibility of the device.
  • the shaft 843 is located near the vertex of the cavity C1 which connects the edges 883 and 884.
  • the cavity C1 allows to receive the first and second links 841 and 842 in a configuration where they block a translation of the carriage 82 and the tab 10 under the effect of a force exerted F3 on this tab.
  • These elements thus constitute means of irreversibility of the actuator 8 in the first position of the carriage 82.
  • These means do not oppose a displacement of the carriage 82 and the lug 10 under the action of the electric motor 86, since the rotation of the pinion in the direction of the arrow R2 makes it possible, thanks to the force T4, to realign the links 841 and 842 with the other links of the chain 84.
  • the wedge 89 makes it possible to slightly offset the shaft 843 in the direction of the cavity C1 when this shaft passes over the wedge which is projecting with respect to the edge 102. This makes it possible to initiate the "folding" movement of the chain between the links 841 and 842, in a direction where the shaft 843 is engaged in the cavity C1.
  • the shim 89 may be replaced by another system which pushes the shaft 83 towards the cavity C1, for example a system comprising a spring and a ball.
  • a mechanical device can be provided for exerting on the links 841 and 842 in the configuration of the figures 2 and 3 a force E5 perpendicular to the axes X86 and A88, in order to push towards the housing L1 the parts of the links 841 and 842 engaged in the cavity C1.
  • a force can be exerted by means of a pin embedded in the core 88 and protruding from its edge 886 opposite to the edge 881.
  • the application of the force E5 makes it possible to eliminate the irreversibility obtained at the level of the cavity C1 , in order to mechanically unlock the actuator, for example in the event of a power failure.
  • the irreversibility means constituted by the cavity C1 and the links 841 and 842 make it possible to protect the motor 86 in the event of heavy force exerted on the lug 10 in the direction of the arrow F3, for example in the event of high wind or of choc.
  • the cavity C1 borders the housing L1, being adjacent to the zone Z1, and opens into this housing through the interrupted portion of the edge 101 whose trace defines an immaterial limit between the volumes L1 and C1, namely the edge 882
  • the cavity C1 may be provided to receive more than two links of the chain 84.
