Definitions

  • the present invention relates to an operator for a door with at least one leaf with automatic closing and opening, in particular of an elevator car, in particular of the accordion type comprising at least one folding leaf element.
  • the invention also relates to a swing door with automatic closing and openings, in particular of an elevator car, actuated by an operator of the aforementioned type.
  • switches of the tear-off type, comprise in a known embodiment, at least one movable contact mounted on a leaf element pivoted on the door which cooperates, at the end of pivoting of this leaf element, with a fixed contact integral with the fixed amount of the clapper.
  • the life of such switches is limited and moreover, these switches are unreliable because it may happen that the end leaf element is no longer guided in its guide rail but that the closing contact is nevertheless established. so that the elevator car may leave when its door is not or is not closed properly.
  • An object of the invention is to provide an operator for a door with at least one leaf with automatic closing and opening, in particular of an elevator car, in particular of the accordion type comprising at least one folding leaf element, which is of design robust and reliable, that is to say in particular of which it is certain that the elevator car fitted with such a door will not leave until the door is actually closed and which also draws the number of opening-closing sequences related to the utilization rate of the elevator car.
  • Another object of the invention is to improve the aforementioned operator by providing it with torque limiting means which are capable of effectively controlling in sequence the interruption of the closing of the leaf and the reopening of this leaf in the event of blockage to the closing of it.
  • the invention also aims to propose an operator who adapts to elevator car doors of variable width and which can also be installed above or below the door.
  • the operator further comprises means for guiding in linear displacement of the free end of the leaf, this leaf comprising for example a first leaf element pivoted by said rotary drive means and at least one leaf element articulated on the first.
  • the aforementioned combination of means makes it possible to produce an operator whose operation is extremely reliable even after ordering a very high number of door opening and closing sequences.
  • the means for guiding in linear displacement of the free end of the leaf associated with the first end of stroke sensor means of the free end of the leaf secured to this free end and cooperating with these second end of stroke sensor means of said free end integral with the operator's chassis make it possible to reliably deliver a signal which authorizes or not the departure of the cabin.
  • the torque limiting means comprise a slide coaxial with the first pinion and made integral in rotation with the latter and this slide is held in abutment against the first pinion by means of biasing means elastic arranged between the internal face of the slider and an end opening of the output shaft of the motor, the means for securing the slider to the first pinion being designed so that a blocking of this first pinion causes a translation of the slider towards the end of the output shaft opposite the motor and that these cam-forming means projecting radially from the external face of the slide cooperate with a fixed contact secured to the operator's chassis to control in sequence the interruption of the closure and reopening the leaf.
  • the means for securing the slider to the first pinion comprise at least two conical projections regularly distributed on the periphery of the surface of the first pinion adjacent to the slider and housed in corresponding recesses in the base of the slider and for securing the first pinion with the output shaft of the torque motor is obtained by keying with play in the circumferential direction while the internal face of the slide has at its end opposite the first pinion grooves regularly distributed and forming with the external surface of the end opening of the output shaft of the housings for balls facilitating the relative movement of the slide and the output shaft.
  • cam means are arranged in such a way relative to the external surface of the slide that in the closed position of the leaf, said means escape the fixed contact secured to the chassis.
  • the guide means in linear displacement of the free end of the leaf comprise a carriage mounted, at each end of the free end of the leaf, sliding relative to a guide rail which stretches over the width of the door, while at least one of the carriages carries a device for actuating an end-of-travel contact of the leaf integral with the operator's chassis.
  • the second pinion is made integral in rotation with a first drive pulley of a toothed belt made of relatively inextensible material , itself integral in rotation with a second pulley for driving in rotation a rotary drive axis of one of the leaves, this second pinion also meshing a toothed sector for driving in rotation of the other leaf .
  • This planetary arrangement of the sprocket drive pinions as well as the use of a toothed sector for the rotational drive of one of the leaves makes it possible to limit the size of the operator according to the invention.
  • the means for actuating the leaves are mounted on support plates fixed in adjustable position on an operator base in order to adjust the distance between the pivoted ends of the leaves to allow them to adapt to a door of variable width.
  • a door with at least one leaf with automatic closing and opening, in particular of an elevator car characterized in that it is actuated by an operator having at least one of the aforementioned features.

  • each leaf 2 a , 2 b could for example comprise three or four leaf elements depending on the width of the door.
  • the fastening means, which will be described later, of the slide 20 to the first pinion 5 are designed so that a blocking of this first pinion 5, due to an unexpected blocking of the closing of the leaves 2 a , 2 b , cause a translation of the slide 20 towards the end of the output shaft 4 opposite the motor 3 and that cam means 23 projecting radially from the external face 20b of the slide 20 cooperate with a fixed contact 24 secured to the frame 12 of the operator 1 which delivers, so known an electrical signal to the motor 3 for controlling in sequence the interruption of the closing of the leaves 2 a , 2 b and a reopening of these leaves 2 a , 2 b .
  • Contact 24 is for example a switch contact or the like.
  • the means for securing the slide 20 to the first pinion 5 comprise (see FIG. 6) three conical projections 25 regularly distributed around the periphery of the surface 5 a of the first pinion 5 adjacent to the slide 20 and, during normal operation of the leaves 2 a , 2 b , housed in corresponding recesses 26 of the base 20 c of the slide 20 which is in the general form of a cylindrical sleeve whose end adjacent to the first pinion 5 is partially closed by said base 20 c which comprises, on the side of the first pinion 5, an axial bore for the passage of the output shaft 4 and said recesses 26.
  • the end opening 22 of the output shaft 4 is in the form of a blind sleeve of generally frustoconical shape, the end opposite to the first pinion 5 is screwed axially on the output shaft 4 and which has an axial bore into which the end of the output shaft 4 is introduced, a longitudinal key 27 of which is housed in a longitudinal groove of said bore of the frustoconical sleeve 22.
  • This end sleeve 22 of the output shaft 4 also has an external annular radial projection 28 which forms a stop for the end of the helical spring 21 opposite the first pinion 5, the other end of this spring 21 being in abutment on the face of the base 20 c of the slide 20 opposite the first pinion 5.
  • the internal face 20 a of the slide 20 has at its end opposite the first pinion 5 of the grooves 29 regularly distributed over this internal surface 20a, for example three grooves, and forming with the external surface 22a of the end sleeve 22 of the output shaft 4 housings with an axis parallel to the output shaft 4 for balls 30 facilitating the relative movements of the slide 20 and the sleeve 22.
  • the balls 30 which are two in number per groove 29, could of course be replaced by any other suitable "lubricating" device such as rings of the METAFRAM brand (registered trademark ).
  • the securing of the first pinion 5 with the output shaft 4 of the torque motor 3 is obtained by keying with play in the circumferential direction (see Figure 6).
  • the surface of the axial bore of the first pinion 5 comprises a longitudinal keyway 31 in which is housed, with play, the key 27 secured to the output shaft 4.
  • the output shaft rotates through the end sleeve 22 and the balls 30, the slide 20, the walls 26a of the recesses 26 of which slide upwards, that is to say say on the side opposite to the first pinion 5 on the sides 25a of the conical projections 25 of the first pinion 5, so that the slider 20 slides upwards, relative to the sleeve 22, and that the cam 23 comes into contact with the switch 24 which then delivers the signal to interrupt the closing of the leaves 2a, 2b and the reopening of the said leaves.
  • cam means 23 are arranged in such a manner relative to the external surface 20b of the slide 20, that in the closed position of the leaves 2a, 2b, said means 23 escape the fixed contact of the switch 24 secured to the chassis 12 so as not to order an unexpected reopening of these leaves.
  • the guide means in linear displacement of the free end 10a, 10b of each leaf 2a respectively 2b comprise a carriage 13a respectively 13b mounted, at each end of the upright 35a respectively 35b forming the free end 10a respectively 10b of each leaf 2a respectively 2b, sliding with respect to a pair of upper and lower guide rails 37 and of each leaf 2a, 2b which extend over the entire width of the door.
  • the mobile devices 39a, 39b are electrically conductive fingers which, in the closed position of the leaves 2a, 2b, are inserted between two fixed contacts 40a or 40b forming a plug to close a circuit which then delivers the signal by question.
  • the second drive pinion 6 meshed by the first pinion 5 is made integral in rotation by means of an axis 4 of a first notched pulley or roller 42 for driving a belt 43 itself integral in rotation with a second notched pulley or roller 44 of rotary drive of the rotary drive axis 7a of the pivoted end of the leaf 2a, this second pinion 6 also meshing a toothed sector 45 of rotary drive of the rotary drive axis 7b of the pivoted end on the other wing 2b.
  • the aforementioned belt 43 is for example a notched strip of synthetic material such as rubber or the like but in any case relatively inextensible, the two ends of which are connected by means of a device forming a graph 50, known in itself, and stretched by means of a tensioner device 51, also known in itself and not specific to the invention.
  • the second pinion 6 is further made integral in rotation with an arm 52 (see FIG. 1) which cooperates with a stop 53 limiting the angular travel of the second pinion 6 and consequently that of the belt 43 and of the toothed sector 45, limiting thereby the angular displacements of the rotary drive axes 7a, 7b of the leaves 2a respectively 2b.
  • the planetary configuration of the leaf actuation means 2a, 2b that is to say the rotational drive of the pulley 42 which carries the belt 43 and of the toothed sector 45 which controls the rotation of the axis 7b by the second pinion 6, gives the operator 1 according to the invention a minimum size.
  • the use of a toothed sector 45 for controlling the rotation of the axis 7b also contributes to the reduction of this bulk.
  • the means for actuating the leaves 2a, 2b that is to say in particular the torque motor 3 and the associated gear means 5, 6 and 45, as well as the pulleys 42 and 44 and that the axes 7a and 7b of drive in rotation of the pivoted ends of the leaves 2a, 2b, are mounted on support plates 52a, 52b fixed in adjustable position, for example by means of rails 54 and suitable screws (see Figure 1) on a fixed base of the chassis 12 of the operator 1 to adjust the distance between the pivoted ends of the leaves 2a, 2b to allow them to adapt to a door of variable width.
  • This characteristic is particularly advantageous when it comes to equipping already old elevator cars with automatic closing doors and openings actuated by an operator according to the invention.
  • the operator according to the invention therefore makes it possible to produce an accordion type swing door with automatic closing and opening for an elevator car, the operation of which is extremely reliable even after a very large number of opening and closing operations.
  • the space requirement of the operator being reduced, it is very easy to install such an operator on existing installations, that is to say for example old elevator cars which are not yet equipped with interior door with automatic closing and opening.
  • the invention is not limited to the examples described and shown.
  • the operator who has been shown in the high position of the cabin, that is to say above the leaves 2a, 2b, could very well be disposed in the pass position, that is to say under the leaves 2a 2b.
