Definitions

  • This invention relates to elevator cars and, more particularly, to the construction of an elevator car door clutch attached to the elevator car door that contacts the drive rollers with an adjacent landing door to simultaneously actuate a landing door and a powered elevator car door.
  • the door of an elevator car is brought into open and closed positions relative to the elevator entrance by means of a door drive mounted on the roof of the car.
  • the cabin, the door drive and the cabin frame are collectively referred to below as the elevator cabin.
  • the landing doors on each floor of a building served by an elevator car are opened by the elevator on the corresponding floor, and a coupling attached to the elevator car has "opening” and “closing slides” which hold the corresponding elements of the landing door, such as the landing door drive rollers in Open or close in accordance with the elevator door.
  • the present invention is an elevator car, including an improved door clutch with controls that reduce the noise associated with the operation of the door clutch while allowing the elevator car and landing doors to be uncoupled by authorized personnel without the need to do so the contact between the elevator car door coupling and the shaft door drive rollers is damaged.
  • the design of the coupling also enables the door to be locked and unlocked automatically.
  • the elevator car door clutch is rotatably attached to the elevator car door, the clutch being biased into an operating position toward a landing door by a bias that can be released by authorized personnel. Manually turning the cabin door coupling against the force of the preload enables the coupling to temporarily take a position in which there is a gap between the coupling slides and the shaft door drive rollers.
  • the elevator car door coupling is automatically switched from a first configuration, which ensures a clearance of a good 0.6 cm (0.25 inch) between the opening slide and an adjacent shaft door drive roller as well as between the closing slide and an adjacent shaft door drive roller in the travel mode
  • the closing slide is gently placed against one of the shaft door drive rollers, while the opening slide makes contact with the other shaft door drive roller. Little noise is generated in connection with the movements of the coupling and the drive rollers and the mechanical wear on the elements of the elevator car and shaft doors that come into contact with one another can be considerably reduced.
  • the automatic change of distance between the opening and closing slides is only relative to the position of the elevator car door. The positions of the, on the door operator attached door arms are not used for this.
  • a cam and a cam follower are fastened, such as by attaching the cam to the elevator car and the cam follower to the elevator car door, so that they move relative to the movement of the elevator car door.
  • a change in height when the cam follower contacts and then follows the cam is used to change the gap between the slides.
  • the gap between the slides is reduced when the elevator car door begins to open, with the closing slider moving towards the opening slider.
  • the movement in connection with the change in position of the closing slide is opposite to that of the elevator car door.
  • the cam is designed so that it gently and slowly moves the closing slide towards the opening slide at approximately the same speed as the elevator car door moves in the opposite direction. The relative speed between the closing slide and the shaft door drive rollers is therefore zero.
  • the cam follower makes contact with the cam and moves it in order to enlarge the space between the opening and closing slides and thus the space required for operation between the Sliders and the adjacent shaft door drive rollers to create when the elevator car moves through an elevator shaft.
  • the closing slide is attached to a parallelogram-shaped connecting device, wherein it reaches the position for driving operation in one direction into a position which ensures the clearance for driving operation, by lifting it by means of the cam follower, and from it in the cam follower Position is held and it swings to the contact position with the shaft door in the opposite direction, this Motion is created by gravity when the cam follower moves the cam down.
  • the door coupling comprises a base surface which is attached to the cabin door, a frame which is rotatably fixed to the base surface and to which the closing slide is fastened, and the opening slide rotates in the same axis of rotation as the frame which supports the closing slide the base is attached.
  • Preloading devices in the form of springs tension the opening and closing slides outwards, away from the large, flat surface of the elevator door towards the shaft door walls and shaft doors. This is the normal operating position of the door clutch.
  • the shaft door drive rollers and clutch slides can be moved past each other by a horizontal movement relative to the said elements by manually depressing the clutch slides against the pretension of the springs, and can therefore be uncoupled easily and without the risk damage to the shaft door drive rollers or clutch slider.
  • the opening slider is designed to include fixed and movable plates connected by means of a parallelogram connector, resulting in a small movement of the moving plate when contact is made with a shaft door drive roller to begin the opening process. This small movement is translated into a lifting movement that lifts a door locking pin from an opening in the door sill of the elevator car in order to unlock the elevator car door. If a passenger should attempt to open the elevator car door when the elevator car door coupling is not near a shaft door roller, the locking pin remains in the door sill of the elevator car and prevents the door from opening over a small one, by the length of the opening or the Slot in the doorway defined area is opened.
  • FIGS. 1 and 2 a front view of an elevator car 10 is shown in FIGS. 1 and 2, as can be seen from the shaft door side.
  • a shaft door is not shown in FIGS. 1 and 2, but a shaft door 12 of the elevator car 10 is shown in the partial view from the right in FIG. 4.
  • the elevator car 10 includes a car 14, which may be of conventional construction, with an opening 16, best seen in FIG. 2.
  • the car 14 comprises a head part 18 above the opening 16, a door sill 20 below the opening 16 and a hanging roller rail 22 attached to the head part 18 above the opening 16.
  • the car 10 comprises an elevator door 24 with one or more door fields 26 and 28 which are shown here for example purposes only.
  • the door panel 26 comprises vertically oriented leading and trailing edges 30 and 32, horizontally oriented upper and lower edges 34 and 36 and outer and inner, flat main surfaces 38 and 40, respectively, which form vertically oriented surfaces.
  • the hangers 42 and 44 or their functional equivalents are on the upper edge 34 of the Door panel 26 attached, the hanging bearings 42 and 44, including the associated hanging rollers 46 and 48, are carried by the flange 50 of the hanging roller rail 22.
  • the guide strips like the guide strips 52 and 54, are attached to the lower edge of the door panel 26 and are located in a longitudinal groove 21 in the door sill 20.
  • a retractable object sensor edge 56 can accordingly be attached to the guide edge 30 of the door panel 26.
  • the door panel 28 corresponds to the door panel 26 up to this point and is therefore not described in detail.
  • FIG. 3 is an exploded perspective view of the door coupling 60, and FIG. 3 together with FIGS. 1 and 2 are referred to in the following description of the door coupling 60.
  • Each landing door 12 includes elements with which the door coupling 60 makes contact; for example, these are referred to as drive block rollers or simply as shaft door drive rollers.
  • First and second landing door drive rollers 64 and 66 are phantom in FIG. 1 4, and the shaft door drive roller 64 can be seen in FIG. 4.
  • the door clutch 60 is comprised of the first and second slider devices 68 and 70, the first slider device 68 being referred to as an "opening slider” because it makes contact with the shaft door drive roller 66 to unlock and open the shaft door 12 when the elevator door 24 is opened.
  • the second slide device 70 is referred to as a "closing slide” because it makes contact with the shaft door drive roller 64 when the shaft door 12 is closed when the elevator door 24 is closed.
  • a force of the opening slide device 68 on the shaft door drive roller 66 causes the shaft door drive roller 66 to rotate against the shaft door drive roller 64 until the shaft door drive roller 66 has made contact with the shaft door drive roller 64.
  • This movement of the shaft door drive roller 66 is implemented by means of a mechanical connection which unlocks a conventional shaft door lock. The shaft door lock is therefore not described in detail.
  • the gap 72 between the opening and closing slides during travel is a good 9.5 cm (3.8 inches)
  • the operating gap 74 between the opening and closing slides when the elevator stops is the shaft door drive rollers 64 and 66 have made contact and the sliding devices 68 and 70 have close contact with the landing door drive rollers 64 and 66, perhaps a good 7.5 cm (3 inches).
  • the present invention changes the space between the opening and closing slides 68 and 70 without using the door drive function.
  • any door drive can be used to drive the door clutch 60 without any modifications or adjustments.
  • the only adjustments required are the locking depth and the space between the opening and closing slides. The change in the space is completely and directly dependent on the position of the elevator door.
  • the door coupling 60 specifically includes a carrier 76 and the closing slide device 70, which in turn comprises a closing slide 71 and is carried by the carrier 76 by means of upper and lower connecting devices 78 and 80, respectively, which form a parallelogram-shaped connecting device 81.
  • the upper connecting device 78 includes a support arm 82 mechanically connected to the support 76, a slide support arm 84 attached to the closing slide 71, a rotary arm 86 rotatably connected to the support arms 82 and 84 via axes of rotation 83 and 85, respectively, and a stop bracket 88 which detects the movement of the closing slide 71 limited.
  • Bracket 88 ensures that the closing slide 71 cannot rotate in such a way that the axis 85 of the rotating arm 86 reaches a vertical line through the axis 83.
  • the lower one closes similarly Connecting device 80 includes a support arm 90 mechanically connected to the support 76, a slide support arm 92 attached to the closing slide 71, a rotary arm 94 rotatably connected to the rotary arms 90 and 92 via the rotary axes 91 and 93, and a movement limiting bracket 96.
  • An operating or connecting clip 98 is attached to the upper end of the closing slide 71.
  • the process of lifting the operating clamp 98 rotates or swings the closing slide 71, as shown in FIG. 1, upward to the right.
  • the operation of lowering the operating bracket 98 allows the gate valve to gravitationally swing downward to the position shown in FIG. 2.
  • the closing slide 71 can only swing downwards until the axis of rotation 85 is a little bit by the support arm 84 below a horizontal plane formed by the axis of rotation 83 together with the support arm 82, and until the axis of rotation 91 by the support arm 92 is below a horizontal plane formed by the axis of rotation 93 together with the support arm 90.
  • any force generated during the closing process will attempt to hold the slide 71 in the locking or driving position.
  • the mechanical lifting or lowering process which causes the closing slide device 70 to swing back and forth between the driving and operating positions is directly dependent on the position of the elevator car door.
  • the relative movement between the cabin door 24 and the cabin 14 is implemented to operate the door coupling 60 by means of a cam and cam follower device 100, which comprises a cam 102 and a cam follower 104.
  • the cam 102 is attached to the cabin 14, that is, on the hanging roller rail 22, and a cam follower device 104 is attached to the door panel 26, that is to say on the hanging bearing 42; these positions can be reversed if desired.
  • the cam follower is, in particular, part of a clutch drive device 105, which comprises a support plate 106 attached to the hanging bearing 42, a drive arm 108 with one end rotatably attached to the support plate 106 - as indicated by pivot pin 110 - and a second end 112.
  • the cam follower 104 is attached to the drive arm 108 between the pivot 110 and the second end 112.
  • the second end 112 of the drive arm 108 is connected to the clamp 98 in such a way that the desired slide spacing 74 shown in FIG. 2 can be adjusted by means of a threaded rod 114 with a rotary turnbuckle 116.
  • the cam 102 has an inclined surface with which the plunger makes contact.
  • the door 24 is moved in its guidance by a door drive 62.
  • the door panel 26 is moved by a door drive arm 118 which is connected to the carrier 76 of the door coupling 60 by means of a connection 120 rotatably attached to the coupling carrier 76 and the rotating arm 118.
  • the door panel 28 is moved by a door drive arm similar to the arm 118, the arm being connected to the door panel 28 by means of a connection 122 similar to the connection 120.
  • the closing slide device 70 In the operating description of the closing slide device 70, it is first assumed that the door 24 closes and the door field 26 moves to the left, as shown in FIG. 2. As the door panel 26 now approaches the fully closed position shown in FIG. 1, the cam follower 104 makes contact with the cam 102, moves it, lifts the rod 104 and swings the closing slide device such that the closing slide 71 moved in the opposite direction to the closing door field. This creates a gap for driving between the closing slide 71 and the shaft door drive roller 64 when the cam follower 104 has reached a stop at the end of the inclined part of the cam 102.
  • the cabin door 24 has a cabin door lock 124 which is operated by means of the door coupling 60.
  • the door coupling operation of the door lock 124 is ensured by the opening slide device 68 so constructed that there is a predetermined mechanical movement that unlocks the elevator car door 24 when the opening slide device 68 exerts an opening force on the shaft door drive roller 66. If the elevator car door 24 is moved by a passenger when the opening slide device 68 is not in the vicinity of a shaft door drive roller 66, no mechanical door unlocking movement is carried out and the elevator car door 24 remains locked.
  • the opening slide device 68 comprises an opening slide 126, an opening slide carrier plate 128, an upper and a lower pivot arm 130 and 132, respectively, which rotate the opening slide 126 with the carrier plate 128 connect, and the Sliders 138 and 140.
  • the opening slide device 68 there is a parallelogram-shaped connecting device 141, in which a force exerted by the shaft door drive roller 66 on the opening slide 126, the opening slide 126, as shown in FIGS. 1 and 2, about the axes of rotation 134 and 136 swing left.
  • the lower pivot arm 132 includes an integral, downward extension that extends beyond the opening slider 126 and its support plate 128 to have an actuator for the door latch 124.
  • the opening slider device 68 will therefore contact the landing door drive roller 66 when the elevator car door begins to open and rotate the landing door drive roller 66 against the landing door drive roller 64 to achieve mechanical motion implemented by a conventional linkage around the landing doors to unlock.
  • the shaft door lock is described in a simultaneously filed US patent application (Serial No. 309630) by the same applicant.
  • the parallelogram link 141 rotates to the left as shown in the figures and actuates the elevator car door actuator 142.
  • the parallelogram-shaped connecting device 81 Simultaneously with the link turning to the left 141, the parallelogram-shaped connecting device 81 also rotates to the left, which in addition to contacting each other also brings the two shaft door drive rollers 66 and 64 into contact with the opening and closing slides 68 and 70, respectively.
  • the cabin door latch 124 includes a spring-loaded locking pin device 144 attached to the rear edge 32 of the door panel 26, the locking pin device 144 a locking pin or pin biased downward by a spring (not shown) includes.
  • a motion enhancing lifter or angle lifter 148 is rotatably attached to the outer major surface 38 of the door panel 26, the angle lifter 148 having a configuration similar to a right triangle with the unevenly sized first and second sides 150 and 152 and the hypotenuse 154.
  • the side 150 is shorter than the side 152.
  • a pivot bearing 156 is attached close to the right angle formed by the two sides 150 and 152; an actuating element 142 is connected to the corner of the lifter 148 formed by the shorter side 150 and the hypotenuse 154, for example by means of a threaded rod; 158 and 160 and a connecting turnbuckle 162 and a rod or cable 164 connect the end of the lifter 148 formed by the longer side 152 and the hypotenuse to the locking pin 146.
  • the elevator door sill 20 defines a longitudinal groove 21 of the guide rail, represented by 166, an elongated slot.
  • the opening slide 126 In operation of the door latch 124, when the door panel 26 of the elevator car door 24 reaches the fully closed position shown in FIG. 1, the opening slide 126 will be in a position in which it is no longer in contact with the landing door drive roller 66.
  • the opening slide 126 can therefore swing downward by gravity and also by a force exerted on the locking pin 146 by means of the prestressed spring, as shown in FIGS. 1 and 2.
  • the dimensions are chosen so that the clearance required for driving operation between the opening slide 126 and the shaft door drive roller 66 is a good 0.6 cm (0.25 inch).
  • the locking bolt 146 is pretensioned such that it projects into the slot 166 in the bottom of the longitudinal groove 21 of the guide rail of the elevator car door sill 20 and prevents the elevator car door panel 26 and the elevator car door panel 28, which changes the position mechanically in relation to the elevator car door panel 26, can be moved beyond the length of the slot 166.
  • the opening slider 126 will make contact with the landing door drive roller 66, swing upward left, lift the elevator 148 clockwise into the, in 2, rotate the position and move the locking pin 146 upward against the spring force exerted downward on the locking pin 146 in order to lift the locking pin 146 out of the locking slot 166.
  • the car door locking device 124 remains in the unlocked configuration shown in FIG. 2 until the elevator car door has again reached the fully closed position, whereupon it is brought back into the position shown in FIG. 1.
  • a vertically oriented cross bar 167 connects the support arms in particular, as can best be seen from the exploded perspective view in FIG. 3 82 and 90 to form a rigid support frame 169 for the closing slide device 70, which is rotatably attached to the support 76 and is biased outwards by the upper and lower springs 168 and 170 into the desired operating position.
  • 5 and 7 clearly show the operating position of the spring 168, FIG. 5 being a partial view, seen from the left, of the door coupling 60 and FIG. 7 being a section of the door coupling 60 according to the arrows VII-VII.
  • the bracket 76 includes a plurality of vertical brackets or projections 172 spaced vertically with vertical openings 174 for receiving the pivot pins 176 and 178.
  • the pivot pins 176 and 178 also connect the openings defined by the bracket arms 82 and 90, respectively 180 and 182.
  • the support plate 128 of the opening slide 126 comprises a plurality of projections 184 spaced vertically with vertical openings 186, said openings also being connected by the pivot pins 176 and 178.
  • the springs 188 and 190 bias the opening slide device 68 outwards into the operating position shown in FIG. 6. 5 and 8 clearly show the operating position of the spring 188, wherein FIG. 8 is a section of the door coupling 60 according to the arrows VIII - VIII.
  • Manually depressing the opening and closing slide devices 68 and 70 against the elevator door 24 and against the bias by the springs 168, 170, 188 and 190 shown in FIG. 9 creates a gap between the opening and closing slides 126 and 71 and the landing door drive rollers 66 and 64 so that the elevator and landing doors 24 and 12 can be uncoupled for maintenance purposes.
