Definitions

  • the invention relates to a safety device, in particular for a sliding door with automatic closing, comprising a movement motor for the movable leaf or leaves with limited closing force and a non-closing detector for signaling the presence of an obstacle in the joint plane of the uprights coming into said closed position on contact.
  • a known safety device of the kind mentioned makes use of detectors for the presence of an obstacle in the plane of the door, capable of preventing the closing or of commanding the instantaneous reopening of the door.
  • detectors for the presence of an obstacle in the plane of the door capable of preventing the closing or of commanding the instantaneous reopening of the door.
  • optical, pneumatic or mechanical detectors, in particular of the sensitive edge type make it possible to keep flexible edges on the edges of the doors preventing bruising, but they are fragile and have the drawback of being an easy command to reopen the accessible door. to the late notified user. The availability of the installation is thus reduced.
  • the door closing force is limited to a non-dangerous value and a door non-closing detector signals the presence of an obstacle.
  • This device does not provide absolute security and it is ineffective for a thin obstacle, such as a piece of clothing or a dog leash, trapped between closed doors.
  • the object of the present invention is to remedy these drawbacks and to allow the production of a device guaranteeing the safety of the user and the availability of the installation.
  • the safety device according to the invention is characterized in that the said uprights bear edges over the whole or almost all of the height, respectively, a male part and a female conjugate part interlocking in said closed position, the presence of an obstacle hindering this interlocking and closing.
  • the preferred application of the invention relates to sliding doors with one or two movable leaves, of transport vehicles, but it is clear that the invention applies to elevator doors and in general to any movable opening panel. .
  • the projecting male part is sheathed by a retractable sheath, which carries flexible edges cooperating with conjugate flexible edges fixed edge to the upright carrying the female part.
  • a retractable sheath which carries flexible edges cooperating with conjugate flexible edges fixed edge to the upright carrying the female part.
  • edges of the flexible lips are preferably profiled to achieve a chicane interlocking, and the play between the male and female parts is sufficiently small to oppose an interlocking in the presence of an obstacle inserted between the two parts.
  • the retractable sheath sheaths the door jamb over the entire height and is arranged to cover all the mechanics while fully retaining the classic aesthetics of the door.
  • leaves 10, 12 of a sliding door are mounted with horizontal sliding and actuated by a motor 86 with limited closing torque of the doors.
  • the drive can be of the friction wheel 88 type or of screw and nut type and with automatic uncoupling during excessive closing resistance.
  • the force of wedge ment of an obstacle, in particular of a person caught between the leaves 10, 12 is thus limited to a non-dangerous value.
  • Sliding doors of this kind equip elevators and transport vehicles and in automatic installations the non-closing of a door stops the cycle, in particular the starting of the elevator or the train.
  • a metal part 22 having two parallel flanges 24 which confine a U-shaped housing 26 open opposite the leaf 12.
  • the flanges 24 are flanked externally by Joints 28, 30, of a hollow elastic profiled material.
  • the rear edge of the seals 28, 30 is embedded by a dovetail 32 in the part 22 and the front edge 34, cut in a bevel, projects from the edge of the U 26. It is easy to see that the whole part 22 , seals 28, 30 constitute a flexible edge of the leaf 10 having a female U-shaped socket 26.
  • a metal part in the form of T 38 shown on an enlarged scale in FIG. 4.
  • the sole 40 of the T 38 is contiguous to the edge 36 and the leg constitutes a blade 42 s extending in the median plane of the door 10, 12 and the front part 44 of which fits in the closed position of the door between the flanges 24 in a U shape.
  • the blade 42 ends in a tip 46 made of a hard elastomeric material wedge shape, which in combination with chamfers 48 of the U 26 input, facilitates the centering and nesting of the male 38 and female 22 parts.
  • a plurality of blind holes 50 pass perpendicularly through the sole 40 and extend into the blade 42 by cutting the lateral faces to define guide openings 52 parallel to the direction of translation of the leaf 12.
  • a piston 54 In each hole 50 is slidably mounted a piston 54, extended by a rod 56 for supporting a compression spring 58 threaded on the rod 56.
  • the spring 58 The spring 58,
  • the pistons 54 constitute sliding supports of a sheath 62, arranged at the movable edge of the leaf 12, which frames and covers in the protruding position the blade 42.
  • the pistons 54 include countersunk sides 64 which are flush with the blade 42 and carry, fixed by rivets 66, two flanges 68, 70, which frame the blade 42, and whose rear edge 72 overlaps the upright 16.
  • the front part of the flanges 68, 70 is constituted by elastic seals 74, 76 similar to the seals 28, 30 of the leaf 10.
  • the front edges 78 of the seals 74, 76 have a shape combined with that 34 of the seals 28, 30, to form in a nested position a baffle seal.
  • the sheath 62 constituted by the flanges 68, 70, sheaths the blade 42 and the front edge 78 covers in the protruding position the end piece 46.
  • the sheath 62 can be pushed back against the springs 58 in a retracted position in which the pistons 54, sliding in the holes 50, come to bear on the upright 16, the seals 74, 76 coming back from the front part 44 of the blade 42.
  • the rear edge 72 of the flanges 68, 70 comes at the level a recess of the leaf 12, for example of delimitation of a window, to preserve the aesthetics of the door.
  • the sheath 62 In the open position of the door the sheath 62 is held projecting by the springs 58 and it hides the blade 42 and the mechanism.
  • the edges 34, 78 of the leaves 10, 12 are made of a flexible material.
  • the sheath 62 remains projecting (FIG. 1) until the two leaves 10, 12 come into contact (FIG. 2).
  • the seals 28, 30 and 74, 76 whose front edges 34, 78 are are fitted into a chicane, constitute a quasi-rigid assembly integral with the leaf 10.
  • the closed position is characterized by a predetermined spacing of the leaves 10, 12 and is signaled by the door closing detector 90 authorizing the starting of the vehicle.
  • FIGS. 7 and 8 illustrate the operation in the presence of a thin and rough flexible obstacle 82.
  • the obstacle 82 deforms by marrying the chicane shape of the edges 34, 78 (fig. 7). Subsequently, the obstacle stuck 82 pushes back the sheath 62 and the end piece 46 comes into contact with the obstacle 82 in the manner described above. The reduced pressing force of the end piece 46 slightly deforms the obstacle 82, but the sinuous shape of the jammed obstacle 82 and its roughness prevent any sliding of the obstacle between the seals 28, 30; 74, 76 and the continuation of the stroke of the blade 42. The complete closing of the door is prevented (fig. 8).
  • a timer causes the reopening and a new closing attempt in a well known manner.
  • baffle fitting of the seals 28; 30 74, 76 and parts 22, 38 ensures a double seal.
