Definitions

  • the invention is a variable speed conveyor which comprises a plurality of movable elongate platforms whose relative displacement varies as the conveyor advances and a handrail mounted at each end of each platform, each handrail comprising a lateral portion which, when the relative displacement of the platform is zero, extends in the direction of advance of the conveyor, and a longitudinal portion at an angle to the lateral portion, the arrangement of the handrails being such that when the relative displacement of the platforms is zero the lateral portions of adjacent handrails cooperate to form safety barriers extending along the conveyor and when the relative displacement of the platforms is greater than zero the lateral and longitudinal portions of adjacent handrails cooperate to form safety barriers extending along the conveyor.
  • variable speed conveyor As an improved system free from the aforementioned disadvantages, a variable speed conveyor has been developed.
  • the variable speed conveyor includes respective rectangular platforms. In a low speed zone the shortest sides of the rectangular platforms are parallel to the direction of advance of the platforms. In a high speed zone the shortest sides of the rectangular platforms are transverse to the direction of advance. In the acceleration and decleration zones each platform moves relative to adjacent platforms in the direction of the longest sides of the rectangles. Thus through the acceleration and decleration zones the relative displacement of the platforms varies, being zero or small in the low speed and a maximum in the high speed zone. Since the respective platforms are adapted to be displaced relative to each other, the handrails used in the conventional fixed-speed conveyors are not suitable for use with a variable speed conveyor, and therefore, it was dangerous to transport continuously a large number of passengers.
  • a variable speed conveyor which comprises a plurality of movable elongate platforms whose relative displacement varies as the conveyor advances and a handrail mounted at each end of each platform, each handrail comprising a lateral portion which, when the relative displacement of the platforms is zero, extends in the direction of advance of the conveyor, and a longitudinal portion at an angle to the lateral portion, the arrangement of the handrails being such that when the relative displacement of the platforms is zero the lateral portions of adjacent handrails cooperate to form safety barriers extending along the conveyor and when the relative displacement of the platforms is greater than zero the lateral and longitudinal portions of adjacent handrails cooperate to form safety barriers extending along the conveyor.
  • the invention provides handrails for assuring safety of a variable speed conveyor which can continuously transport a large number of passengers.
  • the lateral pieces of the handrails are positioned along the opposite sides of the conveyor so that the conveyor is bounded on both sides by the lateral pieces.
  • both the longitudinal and lateral pieces of the handrails are positioned along the opposite sides of the conveyor so that the conveyor is bounded on both sides by both said longitudinal and lateral pieces.
  • FIG. 1 is a schematic plan view of a conveyor provided with preferred handrails, only some of the handrails being shown;
  • FIG. 2 is an enlarged plan view of an essential part of the low speed zone in FIG. 1;
  • FIG. 3 is an enlarged plan view of an essential part of the high speed zone in FIG. 1;
  • FIG. 4 is a transverse cross-Section side view taken along line C-C in FIG. 1;
  • FIG. 5 is a longitudinal cross-section side view taken along line DD in FIG. 1.
  • Reference numeral 1 designates platforms of elongate rectangular shape which jointly forms a conveyor.
  • the platforms 1 are adapted to be displaced in their lengthwise direction with respect to each other while their opposite side edges directed in the lengthwise direction are kept in tight contact with each other, except in a low speed revolving zone shown in FIG. 1.
  • a low speed zone the platforms 1 are moved along their widthwise direction while their relative displacement in the lengthwise direction is maintained at zero.
  • a high speed zone they are moved along a direction transverse to their widthwise direction and the relative displacement in the lengthwise direction is a maximum.
  • an acceleration or deceleration zone the direction of movement of the platforms 1 relative to their widthwise direction is varied continuously while the relative displacement in the lengthwise direction is also varied continuously.
  • handrail mounting spaces 2 of right-angled triangular shape and handrails 3 that are bent at a right angle as viewed from above are integrally mounted on the spaces 2.
  • a longitudinal piece 4 of the handrail 3 is directed along an extension of one side edge of the platform 1, while the other piece, a lateral piece 5 of said handrail 3 is directed to extend from the inner end of the longitudinal piece 4 along a terminal edge of the platform 1.
  • a handrail cover 6 of doorcase type as shown in FIGS. 4 and 5.
  • the distance 1 between the lateral pieces 5 of the handrails 3 disposed at the opposite ends in the lengthwise direction of a platform 1, is selected to be equal to the sum of the maximum relative displacement x of the platforms 1 in the high speed zone plus the width y through which a passenger can pass readily.
  • the space y between a free end of a longitudinal piece 4 of a handrail on one platform and a free end of a lateral piece 5 of another handrail on the next adjacent platform is preselected at such a size that the hand of a passenger will not be pinched therebetween but the body of the passenger will not pass the space.
  • a suitable space is in the range of from 50 mm.
  • the size of the space y between a comer of a handrail 3 and a free end of a lateral piece 5 of another handrail 3 on an adjacent platform 1, is preselected so that the hand of a passenger will not be pinched therebetween but the body of the passenger will not pass through.
  • the size of the space is in the range of 50 100 mm.
  • the platforms 1 are conveyed at a rate of n platforms per unit time
  • the platforms 1 move at a speed of nW per unit time (where W represents the width of the platform 1)
  • W represents the width of the platform 1
  • the platforms 1 move at a speed of nW/sina per unit time (where represents the angle formed between the lengthwise direction of the platform 1 and the direction of movement of the platforms 1
  • the speed in the high speed zone is twice the speed in the low speed zone.
  • the passengers can get on or off the conveyor through the space 1 between the opposite side of handrails 3 of the conveyor consisting of a large number of platforms. Since the lateral pieces of the handrails 3 are aligned in a straight line with only the small space y therebetween, there is formed a safety barrier so that the passengers will be safely guarded by the handrails 3 without having their hands pinched by the handrails nor falling out of the conveyor.
  • a variable speed conveyor which comprises a plurality of movable elongate platforms whose relative displacement varies as the conveyor advances and a handrail mounted at each end of each platform, each handrail comprising a lateral portion which, when the relative displacement of the platforms is zero, extends in the direction of advance of the conveyor, and a longitudinal portion at an angle to the lateral portion, the ar rangement of the handrails being such that when the relative displacement of the platforms is zero the lateral portions of adjacent handrails cooperate to form safety barriers extending along the conveyor and when the relative displacement of the platforms is greater than zero the lateral and longitudinal portions of adjacent handrails cooperate to form safety barriers extending along the conveyor.
  • a conveyor as claimed in claim 2 wherein there is a space of from 50 to 100 mm between adjacent handrails cooperating to form a safety barrier.
  • a conveyor as claimed in claim 3 wherein there is a space of from 50 to 100 mm between adjacent handrails cooperating to form a safety barrier.
