Definitions

  • the present invention relates to electrically wound closure devices, in particular those in which the operation of the movable closure member (fabric or other) is carried out using an electric motor carried by a tubular frame mounted at the very interior of the drum on which said member is wound.
  • FIG. 1 of the drawing appended hereto designates the idling drum which is rotatably mounted around an axial frame 2, which encloses all of the organs of the device and first of all the electric motor 3 associated on the one hand with an automatic brake mechanism 4 and on the other hand to a speed reducer 5 whose output shaft carries the wheel 6 linked to the internal wall of the drum 1.
  • the frame 2 is secured to a socket 7 which is free to rotate relative to a cylindrical bearing provided laterally on a vertical casing 8 in which are housed, in addition to the limit switch device (not visible in fig.
  • the manual drive system consisting of a hollow wheel 9 and an endless screw 10, which is rotated by means of a ring 11 shaped to cooperate with a removable crank.
  • the horizontal shaft which carries the hollow wheel 9 is connected by a planetary reduction mechanism to the sleeve 7, so that when the ring 11 is actuated angularly by the user as an emergency control, the frame 2 is itself even put in rotation and, through the reduction gear 5 provided irreversible, actuates the drum 1.
  • French document 2506529 shows a rotary contact intended to transmit electric currents from a fixed supply to a rotating part arranged coaxially with respect to each other by means of a contact strip split in the manner of a ashamedy arranged on the periphery coaxially between the two parts.
  • the present invention mainly intends to remedy, and this using a rotary collector of new construction, specially adapted to the particular problem to be solved.
  • the rotary collector according to the invention is essentially remarkable in that it consists of two male and female insulating bodies which are capable of fitting one inside the other and whose walls facing each other. opposite have at least three stepped steps forming supports for annular metal discs arranged two by two and connected to two sets of electrical conductors, the connection between the discs which face each other being effected through at least one arched blade integral with the 'one of the discs so that a simple axial thrust exerted on one of the two insulating bodies ensures the transmission of current.
  • fig. 1 is a schematic axial section of a blind device with integrated emergency operation, capable of being fitted with a rotary collector according to the invention.
  • Fig.2 is an axial section on a larger scale, illustrating the arrangement of such a rotary collector and the mounting thereof inside the blind device.
  • Fig. 3 illustrates in perspective the conformation of each of the two insulating bodies of the rotary collector according to FIG. 2.
  • the reference 15 designates the shaft which carries the hollow wheel of the drive system 9-10 enclosed by the side casing 8.
  • the free end of this shaft 15 has a toothing 15 a forming a planetary gear for the planet gears 16 of the epicyclic mechanism interposed between the emergency operating mechanism and the frame 2.
  • first insulating body 19 with a substantially frustoconical profile and the outer wall of which is profiled to present three stepped steps 19 a , each of these forming a support for an annular disc 20 made of beryllium bronze or other metal similar good conductor of electricity.
  • Fig. 3 clearly shows the arrangement of the body 19 and of each disc 20.
  • each step 19 a has recesses 19 b capable of forming housings for projecting radial ears 20 a provided on the opening of the disc 20 corresponding, which is thus angularly retained on its tier. Its retention in the axial direction is ensured by small teeth 19 c formed on the steps 19 a and behind which comes snap the edge of the opening of the disc, as illustrated in FIG. 2.
  • each channel 19 d is introduced one of the three conductors 21 a which make up the cable 21 connected to the motor 3 through a longitudinal passage 7 a of the socket 7; the end of each conductor 21 a is welded to the disc 20 corresponding to the level of an opening 20 b made in one of the ears 20 a of each disc.
  • each disc 20 has, preferably at each of the three ears 20 a , a blade 20 c which is obtained by cutting and which is arched outwards in order to form a current-collecting member, as will be better understood below. after.
  • the insulating body 19 thus formed and equipped, to which one can assign the qualifier "male”, is associated a hollow insulating body, consequently of the "female” type, which has been referenced 22 in the drawing.
  • This body 22 is established at an internal diameter such that the body 19 is capable of coming to fit therein, and its internal wall comprises three stepped steps 22 a corresponding to the three steps 19 a above-mentioned.
  • Each step 22 a provided with teeth 22 d similar to those 19 c of steps 19 a of the body 19, form support for a metal disc 23, also in beryllium bronze, provided with a lateral ear 23 a suitable for coming engage in one of three longitudinal housings 22 b provided for this purpose in the wall of the body 22.
  • each of these housings 22 b corresponds a longitudinal channel 22 c (fig. 2) for the passage of one of the conductors 12 a cable 12 which comes from the side casing 8; in fig. 2 it has been assumed, for the sake of clarity of the drawing, that the channels 22 c are arranged in the same longitudinal plane when in fact they are angularly offset with respect to each other, as appears in FIG. 3.
  • the stripped end of each conductor 12 a is welded inside a perforation 23 b formed in the ear 23 a of the disc 23 which corresponds to it.
  • the assembly of the rotary collector thus arranged is very simple since the wiring is capable of being carried out in the workshop on each of the bodies 19 or 22 which are then fitted and introduced in this state inside the blind device during assembly. constituent elements thereof inside the frame 2.
  • the free transverse face of the body 19 comes to bear against the overhanging heads of the axes 17 of the planet gears 16, while the free transversable face of the female body 22 comes to rest against a fixed inner part 25, constituted in the envisaged case by a cylindrical lateral extension of the casing 8.
  • the axial thrust thus determined causes the elastic deformation of the arched blades 20 c and thus ensures the transmission of the current. No other fixing or assembly is necessary, such that a notable simplification of the assembly operations is obtained, to which is added total reliability throughout the use of the blind device.
  • the plurality of cambered blades or contacts 20 c ensures transmission of the current under excellent conditions, in particular as regards the intensity capable of being transmitted.
