Definitions

  • ABSTRACT A door operator for driving a track guided door through opening and closing cycles, including a rotating shaft and drive member movable therealong in response to rotation wherein the drive member is resiliently coupled to a door.
  • a locking mechanism is provided for locking the door in closed position and an emergency device enables opening of the door when power is not available.
  • the integrated linear door operator of the invention includes a threaded shaft rotatably mounted adjacent to a door being operated thereby and a nut driven along the shaft and coupled to the door.
  • the shaftnut arrangement will be of the type where the shaft is threaded and the nut includes ball bearing threads wherein the efficiency of the arrangement is extremely high, therey enabling the door to be pushed manually between open and closed positions by causing rotation of the screw shaft through a force applied to the nut through the door.
  • the door operator is illustrated as being mounted in compact relation with a door suspension system and therefore in spaced relation above the upper edge of the door.
  • the door operator of the invention could be mounted below the lower edge of a door in the floor especially in the event that there was not sufficient room to mount the operator above the door. In most instances it can be expected that sufficient space will be available for mounting the operator above the door.
  • the movable driving nut is resiliently coupled to'the door by a coupling means to facilitate the cushioning of the operator when striking an obstruction and to permit closing the door under pressure to effect proper sealing of a door sealing edge relative an opening.
  • door edge obstruction sensing means is mounted on the coupling means to sense an obstruction encountered by the door during closing and either recycle the door to open position or interrupt the closing cycle.
  • a unique locking mechanism is provided for locking the door in closed position and which is unlatched at the beginning of an opening cycle by a suitable power device to start the door opening cycle and automatically latched at the end of a closing cycle by movement of the door.
  • An emergency device is also provided for permitting the unlocking and opening of the door in the absence of power to the door operator or otherwise malfunctioning of the door operator.
  • Control of the door operator motor is accomplished by a unique limit switch actuator in the form of a worm wheel driven by a worm gear on the rotatable threaded shaft of the operator which actuates a plurality of limit switches.
  • Door stops are built into the operator thereby eliminating the need to provide same on the car body.
  • a manually operable lock for locking the doors in closed position and cutting the operator out of the train door system is also built into the operator.
  • a crew switch can be built into the operator.
  • Another object of this invention is in the provision of a linear door operator resiliently coupled to the door to enable the door to be closed under pressure and effect a good sealing relation in closed position.
  • a further object of the invention is to provide a unique locking mechanism for locking the door or doors driven by the operator in closed position.
  • a still further object of the invention is to provide a unique limit switch actuator for a linear door operator.
  • Another object of this invention is to provide an integrated linear door operator having a built-in manually operable door lock that when actuated to locked position bypasses the operator in the train door system.
  • FIG. 1 is a front elevational view of a pair of track guided doors on a passenger vehicle driven by the lincar door operator of the invention
  • FIG. 2 is an enlarged front elevational view of the door operator with some parts broken away for simplicity and other parts omitted, and where the parts shown in solid lines illustrate the position of the parts when the door is in closed and locked position, and the parts in dotted lines show the locking mechanism in unlocked position;
  • FIG. 3 is an enlarged top plan view of the door operator and especially of the parts illustrated in FIG. 2;
  • FIG. 4 is a cross-sectional detailed view taken generally along line 4-4 of FIG. 2;
  • FIG. 5 is an enlarged end elevational view of the door operator shown in FIG. 2 and taken generally along line 5--5 of FIG. 2;
  • FIG. 6 is an enlarged detailed front elevational view of the door operator and illustrating particularly the emergency lever arrangement
  • FIG. 7 is a front elevational view of a limit switch actuator as driven from the linear door operator
  • FIG. 8 is a broken elevational view of a door hanger rail with door stops mounted on the ends;
  • FIG. 9 is a detailed elevational view of the obstruction sensor
  • FIG. 10 is a somewhat fragmentary elevational view of bi-parting doors and a manually operable lock associated therewith;
  • FIG. 11 is an electrical schematic diagram of the op erator control circuitry.
  • FIG. 12 is a switch diagram illustrating the relationship of the actuation of the switches to the door opening and closing movements.
  • a door opening 10 in a side wall 11 of a passenger vehicle is illustrated as being selectively opened and closed by a pair of bi-parting track guided door panels 12 and 13, each of which respectively have at their leading edge flexible sealing edges 12a and 13a.
  • the doors are respectively guided along rails or tracks 15 and 16 which are in turn supported by an elongated mounting bar 17 that is in turn suitably fastened to the car body.
  • the door 12 is suspended from the rail 15 by means of a pair of trolleys 18, while the door 13 is suspended from the rail 16 by a pair of trolleys 19.
  • Door stops 20, FIG. 8 are mounted at the opposite ends of the rails 15 and 16 to limit travel of the door panels by limiting travel of the trolleys.
  • the stops are preferably in the form of rubber discs pinned to the rail, and they function to additionally eliminate the need to build stops in the car body. While the operator is shown for driving doors along a straight line, it should be appreciated it could also be used to drive a door that would rotate when opening or have a plug action.
  • the linear door operator of the present invention is also mounted on the mounting bar 17 above the doors and includes a reversible motor 25 that may be either electric, hydraulic, or pneumatic, a pair of screw shafts 26 and 27, one right-hand threaded and the other lefthand threaded, arranged co-axially with the output shaft 28 of the motor and suitably coupled directly to the motor shaft by means of couplings 29 and 30.
  • the screw shaft 26 is rotatably supported by bearing members 31, while the screw shaft 27 is rotatably supported by the bearing members 32.
  • a nut 35 is driven along the screw shaft 26 during rotation thereof and is connected to the door 12 by a bracket assembly 36 whereby driving of the nut effects sliding movement of the door.
  • a nut 37 is driven along the screw shaft 27 and suitably connected to the door 13 by means of a bracket assembly 38.
  • Any type of screw nut drive may be used where the efficiency is such as to allow the doors to be opened in an emergency without power, such as where the application of force to the leading edge of a door by a person will allow the nut to drive the screw shaft, thereby permitting the nut to move along the screw shaft and the door to be moved to an open position.
  • a ball bearing nut and screw drive arrangement will be used. It will be appreciated that the threads of the screw shafts 26 and 27 will be of opposite hand wherein rotation together in one direction will effect opening of the doors, and rotation together in the opposite direction will effect closing of the doors.
  • the door operator of the invention is shown in connection with driving bi-parting door panels, it should be appreciated that it could likewise be used for a single door where a single screw shaft and nut assembly would be utilized. Further, while the operator is shown located above a door, it could be located below the floor.
  • the bracket assembly 26 for interconnecting the door 12 and the nut 35 includes a pair of facing L-shaped brackets 41 having base legs effects a abutting against and secured to the top edge of the door 14 and upstanding legs 41b with openings through which the screw shaft 26 freely extends. It should be appreciated the brackets could be formed as a U-shaped single bracket.
  • Each of the brackets 41 at their vertical portion supports inwardly extending tubular spring guides 46 and 47 through which the screw shaft 26 freely extends.
  • Springs 48 and 49 of equal length and having the same spring rate are supported on the guides 46 and 47 and bottomed at one end on the legs 41b of the plates 41 and at the other end on collars 50 and 51 carried at the opposite ends of the nut 35.
  • the nut 35 is spring mounted between the plates 41 to thereby define a resilient coupling between the nut and the door.
  • the springs could be of unequal length and different spring rates, such as where it might be desired to have more resiliency on closing the doors.
  • the nut-35 is prevented from rotating with the threaded shaft 26 by a guide pin 54 extending laterally therefrom, having a roller 55 mounted on the end and engaging in a track 56 formed longitudinally of the mounting bar 17 as seen most particularly in FIG. 5.
  • the bracket assembly 38 for coupling the nut 37 to the door 13 is identical to bracket 36.
  • the resilient coupling connecting the door to the movable nut enables closing of the door to pressure the sealing edge by such overtravel of the nut as to cause compression of the spring 49.
  • a cushioning of the obstruction force is provided by the springs 48 and 49 of the coupling.
  • coil springs have been illustrated, it should be appreciated that other types of springs may be used to define the spring coupling between the nut and the door. For example, leaf springs could be employed. Further, it should be appreciated that any type of resilient member could be used and as an example of one other than a spring, an elastomeric member could be used to provide the resilient connection between the nut and the door.
  • an obstruction sensor for detecting an obstruction at the leading edge of a door panel during closing can be built into the operator.
  • the sensor can be incorporated in the resilient coupling between the nut and door panel and includes a pin 57 extending from the collar 50 through a hole in bracket portion 41b to align with the actuating arm 58 of a switch 59 mounted on the bracket portion 41b. Collapse of spring 48 caused by an obstruction encountered by the door panel will actuate the switch 59 that may be in a circuit to cause the door panel to recycle open and then close, or to cause the door panel to stop until the obstruction is removed, or cause a reduction of the driving force for the operator.
  • the switch may be provided at either end of the coupling.
  • the door is locked in closed position against movement by a lock wheel 60 mounted on the threaded shaft 26, and a lock pawl 61 which is pivotally mounted on the mounting bar 17 to pivot on an axis extending perpendicular to the shaft 26.
  • the lock wheel 60 is provided with a plurality of circumferentially spaced notches or slots 62 at its periphery into which the pawl portion 63 of the lock pawl engages when the lock pawl is in locking position.
  • the arm portion 64 of the lock pawl 61 normally extends along the vertical when the lock pawl is in locking position, as shown in solid lines in FIG. 2, and is movable to an inclined position, as shown in dotted lines to raise the pawl portion 63 when it is desired to unlock the shaft 26.
  • a solenoid 65 having a plunger 66 engagable with the arm portion 64 of the lock pawl is employed for driving the lock pawl to its unlock position upon being energized.
  • the solenoid is suitably mounted on the mounting bar 17. It should be appreciated that any other type of power actuator may be used to drive the lock pawl to its unlock position.
  • a one-way clutch 67 is provided between the threaded drive shaft 26 and the lock wheel 60 so that the shaft overruns the lock wheel during closing rotation, indicated by the arrow 68, thereby preventing inadvertent breaking of any of the lock weeel teeth or the lock pawl. While any type of one-way clutch may be provided, a pawl and ratchet type is illustrated in FIG. 4. Accordingly, when the lock pawl 61 is in locking position with respect to the lock wheel 60, rotation of the shaft 26 in the closing direction allows the overrunning of the lock wheel but prevents rotation of the shaft in the direction which would cause opening of the door panel.
  • the smooth closing of the door panel, preloading of the door panel leading edge, and locking is accomplished at least in part by the clutch mounting of the lock wheel.
  • the lock pawl might be mounted so that it is spring biased in one direction relative to the rotation of the lock wheel.
  • a holding latch 70 shown in FIG. 2 in solid lines in unlatched position, is actuated to its latched position as shown in dotted lines, upon opening movement of the door to retain the lock pawl in unlocked position and thereafter permit the deenergization of solenoid 65.
  • the holding latch 70 is pivotally mounted to the mounting bar 17 by a pivot pin 71 and continually resiliently biased in a clockwise direction to its actuated position by means of a spring 71a.
  • a nose portion 72 is defined at one end of the holding latch to engage the lower free end of the lock pawl arm portion 64 when the holding latch is in actuated position.
  • the holding latch When closing the door and moving the coupling between the nut and the door toward closed position, the holding latch is de-actuated to trip the lock pawl and allow it to move to locked position by means of a release pin 74 carried on the leading L shaped plate 41 of the bracket assembly.
  • the pin 74 engages a cam surface 75 defined on the holding latch to cam the latch in a counterclockwise rotation and thereby release the lock pawl 61.
  • a spring may be provided to assert a bias on the lock pawl toward its locked position such as indicated at 64a, thereby providing a more positive movement toward the locked position. Therefore, in event the spring fails, the lock pawl moves to locked position gravitationally.
  • an emergency handle 80 connected to a link 81 suspended from an arm 82 of an emergency lever 83 may be pulled downwardly to rotate the emergency handle in a counterclockwise direction about its pivot 84 to drive a cam member 85 against the lock pawl arm 64 and raise the pawl portion 63 to its unlocked position, and further rotation of the emergency lever 83 will cause a roller 86 carried on an arm 87 of the emergency lever to engage the adjacent door trolley 18 and drive it toward the open position. Because of the efficiency of the nutscrew shaft drive, it is then possible to move the door to open position by the exertion of pressure against the leading edge of the door.
  • a manually operable locking device also essentially built into the door operator may be provided, such as that shown in FIG. 10.
  • a locking bar 88 is pivotally mounted on a pivot 89 carried by the door operator frame, and includes a bolt 90 selectively movable into openings 91 and 92, respectively, of brackets 93 and 94, which are respectively mounted on the upper edges of the doors l3 and 12.
  • the brackets 93 and 94 overlap so their holes align when the doors are in closed position, wherein the insertion of the bolt by manual movement of the locking bar 00 to the position shown in solid lines effects the locking of the doors in closed position.
  • a bypass or cutout switch 95 is actuated by the locking bar 88 to bypass the operator and essentially remove it from the operation of the door train line.
  • Controlling the operation of the door operator motor and solenoid may be accomplished by the actuation of limit switches operated in time sequence with the opening and closing cycles. While any sort of arrangement may be employed to actuate limit switches, one form according to the invention is illustrated in FIG. 7 which includes a worm gear mounted on the threaded shaft of the operator for rotation therewith and in engagement with a worm wheel 101 rotatably carried by the mounting bar. Dogs may be mounted on the worm wheel adjacent its periphery for engagement with and actuation of limit switches mounted adjacent thereto, or a cam member may be mounted on the worm wheel for rotation therewith, having a peripheral formation capable of suitably operating the necessary limit switches. It can be appreciated that the relationship between the worm gear and the worm wheel will be such that no more than one and preferably about one-half a revolution of the worm wheel will be effected during v the opening or closing cycle of the door operator.
  • a cam 102 is mounted on and rotatable with the worm wheel 101 for actuation of limit switches 103, 104 and 105 arranged in the electrical circuitry for controlling operation of the door operator.
  • limit switch 106 FIG. 2 is actuated by the lock pawl 61 when it moves to unlock position and limit switch 107, FIG. 6, is actuated upon operation of the emergency lever 03.
  • the operation of the door operator can best be understood by reference to the electrical schematic diagram of FIG. 11 and the switch diagram of FIG. 12. It should be appreciated that the positions of the switches in the electrical schematic diagram of FIG. 1 1 are such as when the door is in closed position.
  • Line is connected to the supply potential and when a door open signal is applied to line 111, the opening cycle of the operator is initiated.
  • the door open signal applies an unlock signal to line 112, thereby causing energization of the lock solenoid 65 to drive the lock pawl 61 to unlock position.
  • the lock pawl thereby actuates switch 106 which closes the motor control relay interlock contacts 106a in the motor control relay line 113 to energize the motor control relay 115.
  • traction motor interlock contacts 106b are opened in the traction motors circuit 116 thereby preventing energization of the traction motors when the door is opening or in open position and until the door comes back-to closed position to actuate the switch 106 and close contacts 106b.
  • Contacts 104b which are in a circuit to short out the opening series resistor 118 when closed, are opened at the same time to connect the opening series resistor 1 18 in the motor circuit to assist in slowing down the motor.
  • limit switch 117 is actuated by the cam 102 to open contacts 1 17a and to de-energize the locking solenoid 65 so that it is not energized when the door is in the open position and during the closing cycle.
  • the switch actuator cam 102 actuates the open limit switch 103 to open contacts 1030 in the motor circuit and cause de-energization of the operator motor and allow coasting of the door panel to the fully open position.
  • Removal of the door open signal on the door train line 111 de-energizes the motor control relay 115 and removes the voltage signal from the solenoid unlock line 112 wherein the motor control relay contact arms 1 a and 1 15b resume their original positions as shown in solid lines to cause the operator motor to be energized in the reverse direction for driving the threaded shaft 26 in the direction of clsoing rotation so that the nut 35 and door panel 12 connected thereto is driven toward closed position.
  • Closing resistor 120 is in the motor circuit during the closing cycle in order to reduce the speed of the motor and the linear speed of the door as it moves from open to closed position.
  • the closing limit switch 105 operated by the cam 102 is actuated to open the contacts 105a in the motor circuit and de-energize the operator motor.
  • the release pin 74 carried on the bracket 41 forces the holding latch 70 to move into release position and allow the lock pawl 61 to pivot into locking position with the lock wheel 60.
  • the lock pawl 61 actuates switch 106 which closes the traction motors interlock contacts 106b in the traction motor circuit and opens motor control relay interlock contacts 1060 in the motor control relay line 113.
  • Cam operated switch 105 is actuated during the closing cycle to close the traction motors interlock contacts l05b in the traction motors circuit, thereby allowing the traction motors to be energized.
