Definitions

  • the present invention also relates to a door thus equipped.
  • leaves cannot be operated in one movement. They may, for example, be leaves locked in one of the extreme positions, and it is therefore necessary to ensure unlocking before leaving this position.
  • leaves which pass from the vertical closed position to a horizontal open position by displacement of their upper edge in a horizontal plane while the lower edge lifts towards this plane.
  • the lateral edges of the leaf often have two opposite tenons engaged in slides arranged along the lateral edges of the opening.
  • They can also be watertight sliding doors which are used in particular for access to cold rooms or operating rooms, or even for inter-circulation in high-speed railway wagons. Their weight is generally important.
  • this device has the drawback of requiring actuation by jack which is not always desired for reasons of space, supply of pressurized fluid, maintenance and the like.
  • this device is not advantageous in all applications because the force provided by the jack in the two phases of the movement is necessarily the same. It will be understood that in the case of the watertight door for example, it takes a much greater effort to lift the door from the closed position than to make it slide horizontally thereafter.
  • the device is characterized in that the motor is rotary, and in that the device comprises a screw secured to the shaft of motor outlet and interposed between the motor and a shaft connected to the first mechanism, a threaded nut mounted on the screw and coupled in translation to the second operating mechanism which is movable with the nut between an extreme position corresponding to one of the extreme positions of the door and a transition position corresponding to a state of transition of the door in which the movement control passes from one of the operating mechanisms to the other, means for counteracting the free rotation of the nut with the screw when the nut is at a distance from its transition position, and means for coupling the screw in rotation with the shaft when the nut is in the transition position.
  • the engine is started.
  • the free rotation of the nut being thwarted, the nut moves to its transition position, bringing, by means of the second mechanism, the door into the transition state.
  • the transition state can for example be either a partial opening state, or a state where the leaf is still closed, but unlocked.
  • the second mechanism served for the first phase of the maneuver in one direction.
  • the second mechanism is of little use in the reverse maneuver. This is the case, for example, for certain watertight doors where the first mechanism alone allows the door to be brought back to the low closing position since it is then helped by the weight of the leaf.
  • the device further comprises means which, when the nut is in the transition position, offer some resistance to the return of the nut to the extreme position.
  • the device is used to actuate a door locked on closing.
  • the two successive phases of the operation are the unlocking and then the opening of the leaf.
  • the two successive phases are closing the leaf and then locking.
  • the door comprises a leaf 1 which, in the closed position, is locked by a locking device 2 arranged in the middle of the upper edge of the opening.
  • the leaf 1 formed of articulated segments, can pass by vertical sliding, from the closed vertical position shown in FIG. 1, to an open position in which the leaf is in a horizontal position, substantially at the upper edge of the opening.
  • the leaf is driven from one to the other of these positions by a first operating mechanism comprising a chain 3.
  • a first operating mechanism comprising a chain 3.
  • one of the strands of the chain 3 passes around a return pinion 4, while the other strand passes around a motor pinion 6 linked in rotation to a shaft 7 directed perpendicular to the plane of the opening.
  • the shaft 7 is intended to be driven in rotation by an electric motor 8.
  • a screw 11 ( Figures 2 to 6) is interposed between the output shaft 12 of the motor 8 and the aforementioned shaft 7.
  • the screw 11 is coaxial with the shafts 7 and 12, and it is linked in rotation to the shaft 12. On the other hand, it is free in rotation relative to the shaft 7.
  • the screw 11 On the side of the shaft 7, the screw 11 is supported by a plain bearing 13 arranged in a sleeve 14, keyed at the end of the shaft 7.
  • a nut 16 On the screw 11, a nut 16 is mounted which has on the wall of its central bore 17 a thread which cooperates with that of the screw 11. At its end directed towards the motor 8, the nut 16 carries an end piece 18 connected to the nut 16 proper by a shoulder 19. On the 'end piece 18, are threaded a polymer washer 21 pressed against the shoulder 19, and a metal washer 22 supported, on the motor side 8, against a stop ring 23. Between the washers 21 and 22 are engaged two opposite studs 24, perpendicular to the screw 11 ( Figures 3 and 4). The pins 24 are fixed to the two parallel arms 26 of a lever 27 forming part of the second operating mechanism, according to the invention.
  • the two arms 26 are welded to a sleeve 28 keyed to a shaft 29 perpendicular to the screw 11 and parallel to the studs 24.
  • the shaft 29 is pivotally mounted in the two side walls 31 of a housing 32, having a profile in U, to which the motor 8 is fixed.
  • the rotation of the shaft 29 is controlled by the translation of the nut 16.
  • the shaft 29 is rigidly connected to another lever arm 33 directed opposite the arms 26.
  • the end 34 of a cable 36 is fixed to the arm 33 in a position distant from the axis 29.
  • the cable 36 which is mounted in a sheath 37 whose end is stopped at 38, relative to the housing 32, is directly connected to the locking mechanism 2 of the leaf 1 (FIG. 1).
  • This mechanism is of the type in which unlocking takes place, by means of compression of a return spring 39.
  • a tensioning device 41 is articulated by one of its ends at the end 40 of the arm 33 opposite the shaft 29.
  • the other end of the device 41 is articulated at 43 to a bracket 42 fixed to the side wall 31 adjacent to the U-shaped housing 32.
  • the device 41 comprises a compression spring 44 mounted between two cups 46 and 47.
  • the cup 46 located on the side of the bracket 42 is in abutment at the bottom of a stirrup 48 hinged directly to the lever arm 33.
  • the stirrup 48 is mounted with slide, relative to a rod 49 connected to the bracket 42, and to the other end of which the cup 47 is fixed.
  • the nut 16 At its axial end directed towards the shaft 7, the nut 16 carries a lug 51 directed radially. This is intended to cooperate with a stop 52 formed by a cutout in the side wall 31 of the housing 32 opposite the tensioning device 41.
  • the stop 52 which is bent at 90 ° relative to the wall 31, extends over a certain length, from the end of the U-shaped housing 32 adjacent to the shaft 7.
  • the stop 52 extends substantially in a plane passing through the screw 11 and parallel to the shaft 29.
  • the sleeve 14 (FIG. 2) rigidly carries a disc 53 coaxial with the screw 11 and the shaft 7. Between the disc 53 and the end of the U-shaped housing 32, and in particular between this disc 53 and the end of the stop 52 directed towards it, is provided with a free space L sufficient for the lug 51 to be entirely released from the stop 52 when the nut 16 is in the so-called "transition" position, in which it is in abutment against the disc 53.
  • the disc 53 In a position spaced from its axis, the disc 53 carries a finger or roller 54 (FIGS. 3 to 5) which projects less than L in the direction of the motor 8.
  • the finger 54 is sufficiently distant from the axis of the mechanism so as not to not be struck by the nut 16 proper, when it is in abutment against the disc 53. However, this distance is small enough that the finger 54 can cooperate with the lug 51 of the nut 16.
  • the wall 31 of the housing 32 which already carries the stop 52 carries under it a CHS contact, controlling the change of direction of rotation of the motor 8.
  • the other wall 31 carries an FCL contact controlling when the engine stop is actuated 8.
  • Each of the arms 26 carries a plate 58 for actuating the contact CHS or FCL on the adjacent wall 31 ′.
  • the CHS contact is actuated by the associated wafer 58 when the nut 16 is in the vicinity of its transition position (adjacent to the disc 53), but not quite in this position.
  • the FCL contact is actuated when the nut 16 is in its so-called "extreme" position in which it is adjacent to the motor 8 (FIG. 6).
  • FIG. 7 shows the electrical diagram of the device in the case where the motor 8 is single-phase, with an input terminal N for the neutral and two input terminals M and D on one or the other of which the phase can be connected by means of an inverter 56, depending on whether it is desired that the motor 8 rotates in the direction of raising or lowering of the leaf respectively.
  • the inverter 56 is normally closed on line D.
  • the switching circuit includes a voltage source V. Between this and the earth are mounted c in order the relay 58 controlling the contact 57, a self-maintenance contact 59 of the relay 58, the FCL contact, an FCO contact which is open when it detects the end of the leaf 1 opening, and a push button contact A allowing in all circumstances to cut the power to the motor 8. Between the source V C and a point 61 located between the relay 58 and the contact 59, in parallel with the relay 58, are mounted in series the relay 62 for controlling the inverter 56, and its contact self-maintenance 63. A push button D, normally open, used to start the engine in the direction of descent, is mounted between point 61 and a point 64 located between the FCO contact and button A.
  • a diode 66 is mounted between point 61 and earth terminal 67 of relay 62, its direction going from point 61 to point 67. Between points 67 and 64, a push button is normally mounted in parallel open M used to start the motor in the upward direction, and on the other hand, the normally open contact CHS in series with an FCF contact which is opened by the leaf when the latter is closed but not necessarily locked.
  • the motor 8 therefore starts in the direction of ascent but at this stage it only drives the screw 11 because it is not secured to the shaft 7.
  • the line d action of the tensioning device 41 passes on the side of the shaft 29 opposite the motor 8, so that the device 41 urges the nut 16 towards the motor 8.
  • the lug 51 of the nut 16 is in abutment on the upper face of the stop 52.
  • the nut 16 does not tend to move along the screw 11 but on the contrary tends to turn with it .
  • the nut 16 then reaches the end of the race against the disc 53, in the so-called “transition” position. During its movement from its so-called “extreme” position, it brought with it the lever 27 by means of the pins 24. The lever 27 pulled on the cable 36, so that the door is now unlocked.
  • the lug 51 escapes the stop 52 because it is in the space L which separates the housing 32 from the disc 53. After a possible fraction of a turn, the lug 51 meets the worn finger 54 by the disc 53. Consequently, the rotation caused by the motor 8 continuing, the nut 16, in abutment against the disc 53, must rotate with it, so that the shaft 7 is in direct engagement with the motor 8 and the opening of leaf 1 begins, while the FCF contact closes.
  • the push button D is pressed.
  • the relay 58 is supplied by this button which short-circuits the contacts 59 and FCO currently open.
  • the relay 62 is not supplied, so that the inverter 56 supplies the input D (descent) of the motor.
  • the screw 11 is therefore rotated in the opposite direction to the aforementioned direction m.
  • the nut 16 tends to rotate with the screw 11 and not to return to the motor 8. It thus performs an almost complete revolution until it comes to bear on the 'other side of the finger 54 ( Figure 5) after which it immediately drives the shaft 7 in the direction of descent. As soon as the descent has started, the FCO contact closes and button D can be released.
  • the finger 54 is replaced by a flexible leaf spring 74 in the circumferential direction of the disc 53.
  • the disc 53 carries a cap 76 which at least partially covers the lug 51 when that -this bears against the spring 74 in the direction of closing the leaf.
  • the spring 74 is a leaf spring fixed to the periphery of the disc 53, and it has, near its free end, a tongue 77 directed towards the motor 8 and by which, when it is at rest, it bears against the cap 76.
  • the spring 74 can therefore only flex in the direction of rotation corresponding to the closing of the leaf 1.
  • the spring 74 pressed against the cap 76 behaves like a rigid finger for driving the shaft 7.
  • FIGS. 8 and 9 makes it possible to lighten or even eliminate the tensioning device 41.
  • the arrangements according to the invention are applied to a door whose rectangular leaf 81 carries on its lateral edges two opposite aligned tenons 82 each engaged in a vertical slide 83 extending along the edges vertical of the opening.
  • the tenons 82 are for example at the limit of the lower third of the panel 81.
  • the lateral edges of the latter are each articulated to a rod 84 whose other end is articulated substantially at the upper corner opening correspondent.
  • a shaft 86 is rotatably mounted along the upper edge of the opening and carries rigidly at each end, beyond the lateral edges of the opening, a pulley 87 used for returning a cable 88, one end of which is attached to one of the studs 82 and the other end is attached to a counterweight 89.
  • a leaf thus mounted passes from the fully closed position to the fully open position in two successive phases. From the closed position, the upper edge 91 shifts horizontally without the pins 82 moving appreciably in the slides 83 (1st phase), then the lestons 82 go up in the slides 83 while in the vicinity of the position of total opening, the edge 91 hardly moves any more. Thus, it would be ineffective to want to initiate the movement by stressing the panel vertically from below. We can therefore think of pulling the upper edge horizontally, but this will become ineffective at the end of the movement. It is therefore very difficult to find a single maneuver performing the operation completely.
  • the application of the device according to the invention makes it possible to carry out the maneuver in two phases from a single motor movement. As shown in FIG. 10, this device 92 is mounted on a horizontal plate 93 overhanging the opening on the side (which should be called inner side) towards which the edge 91 moves during the opening of the leaf 81.
  • the first mechanism 96 comprises two wheels with coplanar chains 98.99, surrounded by a chain 101.
  • the wheel 98 is fixed on the shaft 86, which is parallel to the shaft 97.
  • the wheel 99 is fixed on the latter and there is positioned axially to serve as a stop defining the transition position of the nut 16, which in this example is the position remote from the motor 8.
  • the arm oscillating 109 and the link 111 are mounted between the screw 11 and the plate 93.
  • a tension spring 113 is mounted between a point 114 of the plate 93 and a point 116 of the link 111.
  • the lever 112 carries on its underside two rollers 117, 118 with vertical axes, intended to cooperate with a cam 119 shaped as an arch fixed by its ends 121 (FIG. 10) in the vicinity of the middle of the upper edge 91 of the leaf 81.
  • the ends 121 are bent so that, apart from these, the arch 119 extends in a plane perpendicular to the plane of the panel 81 and located beyond the edge 91 of the panel 81.
  • the arch 119 protrudes relative to the face of the panel 81 which is below when the panel 81 is open.
  • the arch 81 is profiled along three sides of a rectangle connected by two angles, one of which, pointing substantially towards the axis H, is replaced by a bevel 122.
  • the roller 118 (fig. 11) is applied externally against the arch 119 while the roller 117 is engaged in the arch 119.
  • the nut 16 is in its extreme position. Seen from above, the axes EFG are substantially aligned while the axes FGH make a salient angle towards the motor 8.
  • the spring 113 whose line of action then passes substantially through the axes G and H, does not exert torque on the rod 111 around the axis G, nor on the lever 112 around the axis H. Any opening force exerted on the edge 91 of the leaf 81, is transmitted by the roller 118 to the lever 112 in the form of a torque clockwise which would amount to moving point G towards point E.
  • the electric motor 8 is rotated in a direction such that the nut 16, immobilized in rotation by pressing the lug 51 on the stop 52 moves towards its transition position, that is to say say moves away from the motor 8.
  • the nut 16 drives the roller 107 which, by means of the link 111, pulls the lever 112 clockwise (seen from above as in FIGS. 11 and 12).
  • the free end of the lever 112 therefore departs from the panel 81 until the roller 117, coming into engagement with the central part of the hoop 119, pulls the hoop and consequently the panel 81.
  • the lever 11 2 When the nut 16 reaches its transition position, in abutment against a flange 120 of the shaft 97 to which the wheel 99 is fixed, the lever 11 2 has then pivoted so that the roller 118 is completely outside the trajectory of hoop 119 (figure 15).
  • the axis F occupies the position F I determined by the position of the nut 16.
  • This position F 'can correspond to two positions G' and G "(fig. 11) taking into account the distances FG and GH.
  • the spring 113 which is more relaxed when G is in G 'rather that in G ", forces the axis G to take the position G '.
  • the spring does not have for this significant effort to overcome because this movement can take place when the panel 81 is no longer engaged with the lever 112, and because on the other hand the roller 107 has a slight clearance between the washers 21 and 22.
  • the motor 8 continuing to rotate, drives the nut 16 in rotation, the lug 51 of which escapes the stop 52, as well as the shaft 86 which, via the cables 88 , raises the pins 82 with the help of the counterweights 89, until the panel 81 is fully opened.
  • the motor 8 is started in the other direction. Given the configuration described above of the broken line EF'G'H, this rotation of the screw 11 cannot cause the nut 16 to return to its extreme position. Indeed, any tendency to such a return causes a bracing of the lever 112 against the stop 123.
  • the nut 16 therefore remains in the transition position, while the shaft 86 is driven so as to raise the counterweights 89 with the help of the weight. of panel 81.
  • the first phase of closing is thus exactly the reverse of the second phase of opening.
  • the arch 119 after having avoided the roller 118 which has remained in its position in FIG. 15, engages with the roller 117 and causes the lever 112 to rotate anti-clockwise. This changes the axis G from G 'to G "( Figure 11), position in which the angle F'G" H is projecting towards the motor 8, unlike the angle F'G'H.
  • the conditions by which the tendency for the nut 16 to return to its extreme position caused the lever 112 to buttress against the stop 123 are therefore defeated.
  • the screw 11 being reversible, the nut 16 is pulled by the lever 112 to its extreme position so that the lug 51 engages the stop 52.
  • the subsequent rotation of the screw 11 causes the complete return of the nut 16 towards its extreme position while the roller 118, coming into contact with the bevel 122, pushes the leaf 81 to the fully closed position shown in FIG. 11.
  • the roller 117 which describes an orbital movement around the axis H, urges the arch 119 in the direction of the opening of the upper edge 91 of the leaf 81 at the same time as it goes back and forth at the bottom of the section 119a (situations II and III).
  • the roller 117 is opposite the section 119b, the leaf is therefore driven by the first mechanism while, the arch 119 continuing its movement, the roller 117 escapes by the open end of the section 119b.
  • the leaf 131 comprises a horizontal upper beam 132 to which are rigidly fixed, in the vicinity of the two lateral edges of the leaf, two vertical columns 133, 134 each of which carries at its upper end a roller with an axis of horizontal rotation 136, 137.
  • Each roller 136, 137 is mounted to rolling on a respective raceway 138, 139 each of which has a hozizontal closing zone 138a, 139a, then a sloping zone 138b, 139b, followed finally by a horizontal zone 138c, 139c, going to the location occupied by the rollers in the fully open position of the leaf 131.
  • the raceway 138 assigned to the roller 136 which is behind the other in the direction of opening is offset downward relative to the other path 139 by a height equal to the difference in level provided by the sloping zones 138b, 139b.
  • the length of column 134 is correspondingly increased relative to column 133.
  • the first mechanism 141 comprises two wheels with coplanar chains 142, 143 surrounded by a chain 140.
  • One of the wheels 142 is fixed to the end of the shaft 147 opposite the motor 8
  • the other 143 is fixed to the end of a screw 144 extending horizontally under the beam 132, parallel to the latter, and cooperating with two nuts 145, 146 engaged in stirrups 148, 149 arranged at the lower end of the columns 133, 134 respectively.
  • Columns 133, 134 are thus. vertically slidable relative to the nuts 145, 146, but are linked in horizontal translation to these and prevent them from turning with the screw 144.
  • the second mechanism 151 comprises a lever 152 articulated at a fixed point 153, carrying at its free end a roller 154 engaged between the washers 21 and 22, and also carrying, between the point 153 and the roller 154, a roller 156 which is substantially pressed against the front end of the beam 132 when the second mechanism 151 is in its extreme position and the leaf 131 is in the closed position.
  • the dimensions and arrangements are such that the slopes 138b and 139b are crossed by the rollers 136 and 137 when the nut 16 is in the transition position. Consequently, the first mechanism 141 is sufficient to move the leaf 131 along the horizontal zones 138c and 138c.
  • the beam 132 moves away from the roller 156. The transmission of the movement takes place via the screw 11, the nut 16, the tubular shaft 147 and the chain 140.
  • the motor 8 On returning to the closed position, the motor 8 is started in the opposite direction.
  • the nut 16 first returns to its extreme position without any useful effect on the leaf 131. Consequently, the nut 16, which can no longer undergo translation, becomes integral in rotation with the screw 11, and therefore causes the screw 144 to rotate. in the closing direction.
  • the leaf 131 finally crosses the slopes 138b, 139b under the effect of its own weight.
  • the invention provides a safe, inexpensive and above all space-saving means for operating a door in two successive phases automatically.
  • the shaft 7 can form an angle with the screw 11, and to cooperate with the nut 16 by bevel gears.
