Definitions

  • the present invention relates to an elevator car door restrictor and car door interlock. escription of the Related Art.
  • the lack of such maintenance typically leads to elevator code violations or breakdowns.
  • these types of restrictors require precise adjustments for them to work, as they require a aligned path throughout the hoistway.
  • the present invention can work independently of any clutch that is used and does not rely on the clutch for the restrictor to work. This means that even if the clutch requires maintenance there will not be a violation or breakdown for a faulty restrictor because the restrictor works independently from the clutch.
  • the present invention is adjustable and can readily conform to a hoistway that is not entirely straight.
  • the present invention only uses one flag in the the unlocking zone and remains locked without the use of flags if the car doors are opened in a locking zone. This reduces the costs associated with equipment, labor and maintenance.

  • the present invention is generally referred to with numeral 10, it can be observed that it basically includes mounting assembly 20, lever arm assembly 40, hook assembly 60, locking assembly 80, flag engagement assembly 100, and electric switch assembly 120.
  • Mounting assembly 20 includes mounting plate 22 that is mounted to the car door of an elevator. As shown in figure 1 , mounting assembly 20 also includes shaft 28 that protrudes through lever arm assembly 40 allowing lever arm 46 to rotate. As shown in figure 2, mounting assembly also includes top stopper pin 24 that maintains hook assembly 60 from rotating too far back. Locking assembly 80 allows hook assembly to properly reset itself on reset portion 84. As seen in figure 2, mounting assembly 20 also includes bottom stopper pin 26 mounted to mounting plate 22 at a height that prevents hook assembly 60 from rotating freely and becoming a nuisance if the door needs to be removed or opened for emergencies or maintenance. In an alternate embodiment, bottom stopper pin 26 can be used to prevent hook assembly 60 from dragging across the sill after clearing locking assembly 80. In an alternate embodiment, shown in figure 6, roller 200 can be used instead of bottom stopper pin 26 to prevent hook assembly
  • shaft 28 can be passed through sleeve bearing 42 to reduce friction, and thus wear and tear, as lever arm 46 rotates.
  • Shaft 28 is inserted through throughhole 41 of lever 46, shown in figure 9.
  • Sleeve bearing 42 encases shaft 28 within throughhole 41.
  • Sleeve bearing 42 reduces the friction between shaft 28 and lever 46 as lever arm assembly 40 rotates.
  • elevator car doors include bumpers or astragals to prevent noise created by the closing door against the strike jamb, if a single-slide or multi-speed door. These bumpers or astragals are also used to limit the noise in center opening doors. In the event that the bumpers or astragals become defective, the elevator car doors close more than they usually would.
  • Top stopper pin 24 accounts for this breakdown possibility and is mounted to mounting plate 20 at a predetermined position so that even if car doors close more than usual, the reset function of hook assembly 60 is unaffected. Top stopper pin 24 is maintained slightly separated from flag engagement arm 102 in the traveling or reset position to account for the possibility of this extra range of motion (due to bumper or astragal failure).
  • lever arm assembly 40 includes lever 46 that rotates about shaft 28. The positioning of shaft 28 and the distance of lever arm 46 have a cooperative relationship so that hook distal end 64 rests on reset portion 84 of locking assembly 80 when car door interlock 10 is in the reset position.
  • Hook assembly 60 includes hook 62 having hook distal end 64 that rests on reset portion 84 when the car door is closed, as previously described.
  • Hook assembly 60 further includes sill distance adjustment members 65; 65a that are adjusted to outwardly extend hook 62 to accommodate the distance between lever arm 46 and the positioning of locking assembly 80 on the elevator sill.
  • pad 66 can be mounted to hook distal end 64 to reduce the coefficient of friction between hook 62 and reset portion 84.
  • locking assembly 80 includes locking cavity 82 that receives hook 62 as it falls forward into the locking position.
  • Locking assembly 80 also includes reset portion 84 upon which hook 62 rests.
  • Reset portion 84 has a sloping gradient that cooperates with the angle of hook distal end 64 to allow hook 62 to slide down when locking and slide up when resetting. The distance between where hook rests on reset portion 84 and locking cavity 82 defines the amount the elevator car door is permitted to open before being restricted.
  • locking assembly 80 also includes locking portion 86 that is kept spaced apart from reset portion 84 by locking cavity 82. Locking cavity 82 is predetermined to be a depth between reset portion 84 and locking portion 86 sufficient to allow enough of hook 62 to come in abutment with locking portion 86 that the opening movement of the car elevator door is restricted.
  • flag engagement assembly 100 includes flag engagement arm 102 that is rigidly and perpendicularly mounted to lever arm 46. Flag engagement assembly 100 also includes flag engagement member 104 that comes into an abutting relationship with a flag F.
  • hook 62 begins to slide down reset portion 84.
  • Flag engagement arm 102 is positioned at a predetermined location on lever arm 46 so that when flag engagement member 104 engages a flag F, lever arm 46 is prevented from rotating further, thereby preventing hook 62 from being lodged into locking cavity 82.
  • the elevator door is then allowed to be opened as hook assembly 60 clears locking assembly 80.
  • the over rotation of lever arm 46 is then stopped by bottom stopper pin 26 preventing hook 62 from being dragged across the sill after clearing locking assembly 80. If no flag F is present, flag engagement member 104 continues to fall forward, lever arm 46 continues to rotate urging hook 62 to become journaled between reset portion 84 and locking portion 86 within locking cavity 82, thereby preventing the elevator door from opening any further.
  • Locking assembly 80 is mounted to the elevator sill using anchoring plate 88, having fastening means 89.
  • Fastening means 89 can include bolts, screws, inserts, welding or other similar methods that can achieve the mounting purpose.
  • Electric switch assembly 120 also includes circuit closing pins 126;
  • male switch portion 124 mounted to flag engagement arm 102 begins to separate from female switch portion 122. This causes circuit closing pins 126; 126a to begin disconnecting from female switch portion 124.
  • An elevator door lock that is compatible with numerous sizes and types of hoistways. Instead of using flags throughout the hoistway where the doors cannot open the present invention only needs the presence of flags in the prescribed areas where the doors are allowed to open. This significantly reduces material, labor and maintenance costs. Also the efficiency of the components ensures safe operation.

Abstract

L'invention concerne un dispositif de verrouillage mutuel de porte de cabine d'ascenseur, lequel dispositif utilise des indicateurs le long d'une cage d'ascenseur dans des zones enregistrées où des portes de cabine d'ascenseur sont autorisées à s'ouvrir. Le dispositif de verrouillage mutuel de porte de cabine d'ascenseur est monté à l'extérieur d'une porte de cabine d'ascenseur à l'aide d'une plaque de montage et comprend un ensemble de verrouillage mutuel monté sur le seuil de la porte de cabine d'ascenseur. Le dispositif de verrouillage mutuel de porte de cabine comprend un levier muni d'un crochet à son extrémité distale. Le système comprend également un bras de prise d'indicateur monté perpendiculairement sur le levier. Quand la porte de cabine est ouverte, le levier commence à coulisser dans l'ensemble de verrouillage. Si le bras de prise d'indicateur vient en prise avec un indicateur sur la cage d'ascenseur, le crochet est empêché d'être logé dans l'ensemble de verrouillage et la porte de cabine est autorisée à s'ouvrir. Inversement, si aucun indicateur ne vient en prise, le levier continuera à tourner, poussant le crochet à être logé à l'intérieur de l'ensemble de verrouillage, de façon à empêcher ainsi la porte de cabine d'ascenseur de s'ouvrir davantage. Dans un autre mode de réalisation, un ensemble de commutateur électrique peut être utilisé pour arrêter les moyens d'entraînement de l'ascenseur. Le commutateur n'est fermé, de façon à activer ainsi les moyens d'entraînement, que quand les portes sont complètement fermées et que le crochet est dans la position de remise à l'état initial.
