Description

  The present invention relates to a step of an escalator that circulates between entrances and exits.

  Conventionally, a tread with an opening formed at the upper stage end, a riser provided at the lower end of the tread, a bracket connected to the tread and the riser, and a rotating pivot provided on the bracket. An escalator step including a moving member is known. The rotating member includes a rotating rod whose intermediate portion is rotatably supported by the bracket, a closing member provided at one end portion of the rotating rod, and a weight member provided at the other end portion of the rotating rod. have.

  Due to the gravity acting on the weight member, the rotating rod rotates about the intermediate portion, and the closing member protrudes upward from the opening portion of the tread. Since the closing member protrudes upward from the tread board, the adjacent steps are closed by the closing member. As a result, an object such as a shoe of a passenger is prevented from being sandwiched between adjacent steps (see, for example, Patent Document 1).

JP-A-11-139740

  However, even when an object is placed on the upper end of the step, the weight of the weight member must be increased in order for the closing member to protrude upward from the step board. As a result, there is a problem that the weight of the entire step becomes large.

  The present invention provides an escalator step that can prevent an object from being caught between steps and can reduce the weight of the entire step.

  The steps of the escalator according to the present invention include a step plate, a riser provided at the lower end portion of the step plate, and an upper end portion of the tread plate, and the horizontal position and the upper step end portion are lower than the lower end portion. And a demarcation comb that is displaced between the upper and lower inclined positions, and includes a first protrusion provided on the riser, the first protrusion being a rear stage. The demarcation comb of the step adjacent to the side is pressed upward to displace the demarcation comb from the horizontal position to the inclined position.

  According to the step of the escalator according to the present invention, the demarcation comb that is displaced between the horizontal position and the inclined position in which the upper stage side end is located above the lower stage side end, and the first provided in the riser And the first protrusion presses the demarcation comb of the step adjacent to the rear side upward to displace the demarcation comb from the horizontal position to the inclined position, so that an object is sandwiched between the steps. This can be prevented. Further, since the first projection pushes the demarcation comb of the step adjacent to the rear stage upward to displace the demarcation comb from the horizontal position to the inclined position, the closing member is displaced by the gravity acting on the weight member. Compared with the conventional apparatus, the weight of the entire step can be reduced.

The grooves 5a are arranged side by side in the width direction of the step 1 so as to be separated from each other. Each groove 5 a is formed extending from the upper end portion of the riser 5 toward the lower end portion. The upper stage protrusion 17 (FIG. 3) of the demarcation comb 9 is inserted into the groove 5a.

  The first protrusion 10 is fixed to a portion on the rear stage side of the riser 5 where the groove 5a is not formed. The first protrusion 10 is in contact with the demarcation comb main body 15 of the demarcation comb 9 in the step 1 adjacent to the rear stage side from below, and can press the demarcation comb main body 15 upward.

  Next, the operation of the escalator according to Embodiment 1 of the present invention will be described. When the ascending operation of the escalator is started by the control device, the step chain 2 is circulated and moved by driving of a driving device (not shown). Thereby, the step 1 is circulated and moved so that the step 1 on the forward path side is raised.

  When the steps 1 circulate and move, adjacent steps 1 in the lower floor horizontal path portion are stepped with each other as these steps 1 move from the lower floor horizontal path portion to the inclined path portion. That is, the step 1 that is in front of the moving direction among the steps 1 that are adjacent to each other rises higher than the step 1 that is behind in the moving direction. At this time, the first protrusion 10 of the step 1 in front of the moving direction comes into contact with the demarcation comb main body 15 of the demarcation comb 9 of the step 1 in the rear of the moving direction.

  Thereafter, as the step 1 in the front in the moving direction rises higher than the step 1 in the rear in the moving direction, the first protrusion 10 that is in contact with the demarcation comb main body 15 moves the demarcation comb main body 15 upward. Press on. As a result, the demarcation comb 9 of the step 1 located behind in the moving direction is displaced from the horizontal position to the inclined position. As a result, if there is an object such as a passenger's foot between adjacent steps 1, the passenger is alerted.

  Thereafter, the steps of the adjacent steps 1 in the inclined path portion become smaller as the steps 1 move from the inclined path portion toward the upper floor horizontal path portion. At this time, the first protrusion 10 of the step 1 located in the front of the moving direction in the adjacent steps 1 is separated downward from the demarcation comb main body 15 of the step 1 located behind the moving direction. Since the demarcation comb main body 15 is not pressed upward, the demarcation comb 9 is displaced from the inclined position to the horizontal position by its own weight.

  As described above, according to the step 1 according to the first embodiment of the present invention, the demarcation comb that is displaced between the horizontal position and the inclined position where the upper stage side end is located above the lower stage side end. 9 and a first protrusion 10 provided on the riser 5, and the first protrusion 10 presses the demarcation comb 9 of the step 1 adjacent to the rear stage side upward to Since it is displaced from the horizontal position to the inclined position, it is possible to prevent an object from being sandwiched between the steps 1. Since an object is prevented from being caught between the steps 1, it is possible to prevent a passenger from falling due to an emergency stop of the escalator caused by an object being caught between the steps 1.

  Further, the demarcation comb 9 of the step 1 adjacent to the rear stage side is pushed upward by the first protrusion 10 to displace the demarcation comb 9 from the horizontal position to the inclined position, so that it is blocked by the gravity acting on the weight member. Compared with the conventional apparatus which displaces a member, the weight of the whole step 1 can be reduced.

  Moreover, since the demarcation comb 9 is displaced by rotating with respect to the tread plate 4, the demarcation comb 9 can be displaced with a simple configuration.

  Further, since the demarcation comb 9 is made of resin, the demarcation comb 9 is destroyed when the passenger's feet are sandwiched between the adjacent steps 1. Thereby, a passenger's leg can be protected.

  Although the first embodiment has been described with respect to the configuration in which the first protrusion 10 is disposed on the portion on the rear stage side of the riser 5 where the groove 5a is not formed, the first protrusion 10 May be arranged in the groove 5 a of the riser 5. In this case, the first protrusion 10 abuts the upper projection 17 of the demarcation comb 9 from below so that the upper projection 17 can be pressed upward.

Embodiment 2. FIG.
5 is a side view showing a step 1 of an escalator according to Embodiment 2 of the present invention. In the figure, the step 1 further includes a second protrusion (displacement device) 18 provided at the lower end portion of the step plate 4.

  6 is a cross-sectional view taken along the line VI-VI in FIG. 5, and FIG. 7 is a plan view showing an upper stage side end portion of the step 1 in FIG. A groove 4a is formed in the rear side end of the tread plate 4 and on the rear side surface. The grooves 4a are arranged side by side in the width direction of the step 1 so as to be separated from each other. Each groove 4 a is formed to extend in the thickness direction of the tread plate 4. Moreover, each groove | channel 4a is formed so that it may connect with the groove | channel 5a (FIG. 4) of the riser 5. FIG. Therefore, the upper stage side protrusion 17 of the demarcation comb 9 passing through the groove 5a of the riser 5 can be inserted into the groove 4a. The second protrusions 18 are disposed only in the grooves 4 a located at both ends of the grooves 4 a arranged in the width direction of the step 1. The second protrusion 18 is in contact with the upper protrusion 17 of the demarcation comb 9 passing through the groove 4a from above, and can press the upper protrusion 17 downward.

  8 is a cross-sectional view taken along the line VIII-VIII in FIG. The end surface of the upper stage side end portion of the upper stage side projecting portion 17 of the demarcation comb 9 is formed such that the upper part is farther from the shaft member 14 than the lower part. As a result, the second protrusion 18 comes into contact with the upper portion of the upper projection 17 of the demarcation comb 9 at the inclined position. As a result, the second protrusion 18 can reliably press the upper projection 17 of the demarcation comb 9 downward. The upper projection 17 of the demarcation comb 9 has the same upper surface as the upper surface of the step board 4 of the step 1 adjacent to the upper step when the demarcation comb 9 is in the horizontal position. A recess for accommodating the second protrusion 18 may be formed so as to be disposed on the top.

  Next, the operation of the escalator according to Embodiment 2 of the present invention will be described. When the step 1 in the lower floor side horizontal path part goes to the inclined path part, the demarcation comb 9 is displaced from the horizontal position to the inclined position as in the first embodiment.

  Thereafter, as the adjacent steps 1 in the inclined path portion move toward the upper floor side horizontal path portion, the steps become smaller from each other. At this time, the first protrusion 10 of the step 1 that is in the forward direction in the moving direction among the steps 1 that are adjacent to each other is separated downward from the demarcation comb main body 15 of the step 1 that is in the rear in the moving direction. Thereby, the demarcation comb main body 15 is not pressed upward. Here, for example, when dust or the like is sandwiched between the lower projection 16 of the demarcation comb 9 and the shaft member 14, the demarcation comb 9 rotates around the shaft member 14 due to its own weight. If this is not possible, the position of the demarcation comb 9 remains in the inclined position. However, when the steps of the adjacent steps 1 are further reduced, the second protrusions 18 of the steps 1 in the front of the moving direction become the upper protrusions 17 of the demarcation comb 9 of the steps 1 in the rear of the moving direction. Abut.

  Thereafter, as the level difference between the adjacent steps 1 decreases, the second protrusion 18 of the step 1 in the front of the moving direction becomes the upper protrusion 17 of the demarcation comb 9 of the step 1 in the rear of the moving direction. Is pressed downward. As a result, the demarcation comb 9 of the step 1 located rearward in the moving direction is reliably displaced from the inclined position to the horizontal position. As a result, when the adjacent step 1 is in the upper floor horizontal path portion, the position of the demarcation comb 9 on the step 1 is surely the horizontal position.

  As described above, according to the step 1 according to the second embodiment of the present invention, the second protrusion that displaces the demarcation comb 9 provided on the step board 4 and in the inclined position of the adjacent step 1 to the horizontal position. 18 is further provided, even when the demarcation comb 9 is not displaced from the inclined position to the horizontal position by its own weight, the demarcation comb 9 can be reliably displaced from the inclined position to the horizontal position.

  Since the second protrusion 18 is provided on the tread plate 4 and presses down the demarcation comb 9 of the step 1 adjacent to the rear stage side, the demarcation comb 9 is displaced from the inclined position to the horizontal position with a simple configuration. be able to.

  The demarcation comb 9 includes a demarcation comb main body 15 and an upper-stage protruding portion 17 protruding from the demarcation-com main body 15 toward the upper stage side. Since the groove 4a into which the upper-stage protruding portion 17 is inserted is formed and the second protrusion 18 is disposed in the groove 4a of the tread plate 4, the upper protrusion of the second protrusion 18 and the demarcation comb 9 It is possible to prevent foreign objects such as passenger shoes from being sandwiched between the side protrusions 17.

  In the second embodiment, the second projecting portion 18 provided on the tread board 4 has been described as an example of the displacement device. However, in the displacement device, for example, the position of the demarcation comb 9 is changed from the inclined position to the horizontal position. An urging member such as a spring that urges the demarcation comb 9 in the displacing direction may be used.

  In the second embodiment, the configuration in which the second protrusion 18 is disposed in the groove 4 a of the tread 4 has been described. However, the second protrusion 18 is disposed in the groove 5 a of the riser 5. It may be.
