Abstract

PROBLEM TO BE SOLVED: To make a cushioning piece elevated in an upper edge part of a lower end side of a main frame in a step, when the step moves in a sloped part of the main frame. SOLUTION: The cushioning piece 14 is equipped via an operation mechanism 12 in the step 4, and the piece 14 is held in a descending position in a horizontally moving portion of the step 4 in the vicinity of a getting-on and -off way of an escalator. The getting-on and -off of a passenger getting on and off the escalator is not disturbed thereby in the vicinity of the getting-on and -off way by the cushioning piece 14. The cushioning piece 14 is displaced to a position elevated from an upper face of the step 4 in a portion where the steps 4 generate a step difference between them to move inclinedly, so as to be arranged in a projected position corresponding to a corner 7 of the upper edge part of the lower end side of the main frame in a step 4. The corner 7 of the step 4 is covered by the cushioning piece 14 when the sloped part is moved, so as to moderate thereby an impact by the cushioning piece 14 when the getting-on and -off passenger is tumbled.

Reference numeral 4 denotes a step, and a riser 6 is provided at the lower end of the step board 5 and the main frame 1.
Are provided, and a corner 7 is formed at the upper end of the riser 6.

Reference numeral 8 denotes a slit-shaped through hole provided at an edge on the lower end side of the main frame 1 in the step 4 and arranged between a plurality of bars 9 formed in the step 4. A follower roller 11 pivotally attached to the lower edge of the lower end of the main frame 1 is provided on the main frame 1 and is arranged along the movement path of the step 4 to guide the follower roller 10 to roll. Rails.

Reference numeral 12 denotes an operation mechanism, which is provided on the step 4 and has one side pivotally attached to a lower side of the upper end of the main frame 1 in the step 4 and extended to a lower end of the main frame 1 in the step 4. The body 13, a cushioning piece 14 made of a soft elastic material such as rubber and attached to the rotating end of the support 13 to form a gap in each through hole 8 and fit therethrough, provided on the lower side of the support 13. An operating body 16 consisting of a rolling wheel pivotally mounted on the leg 15, and a support 13 projecting downward from the lower end side of the main frame 1 in the step 4.
A screw rod 17 inserted with a gap formed therein, a nut 18 screwed into the insertion end of the screw rod 17, a compression coil spring fitted to the screw rod 17 and disposed between the step 4 and the support 13 And a biasing body 19.

Reference numeral 20 denotes a guide rail, which is provided on the main frame 1 and is arranged along the movement path of the steps 4.
Are formed, and a tilt guide portion 22 corresponding to the tilt portion 3 of the main frame 1 is formed. Then, the operating body 16 is guided by the horizontal guide portion 21 to hold the buffer piece 14 at a position lower than the upper surface of the step 4, and the operating body 16 is guided by the inclined guide portion 22 to raise the buffer piece 14 so that the step 4 Displace to a position higher than the upper surface.

In the escalator apparatus constructed as described above, a number of steps 4 are connected and arranged endlessly on the main frame 1, and the following roller 10 is guided by the following rail 11 provided on the main frame 1. Although not shown, the drive roller of the step 4 is guided by the step rail, and the step 4 circulates in the main frame 1. The steps 4 move horizontally in the horizontal portion 2 of the main frame 1 depending on the horizontal posture, and a step is generated between the steps 4 as the stage 4 moves from the horizontal portion 2 to the inclined portion 3. Hold and tilt.

Further, since the operating mechanism 12 is provided on the step 4 and the support 13 is urged downward by the urging body 19, the buffer piece 14 is also urged downward. Then, the operating body 16 is supported by the horizontal guide portion 21 of the guide rail 20 near the entrance of the escalator, and as shown in FIG.

As described above, the operating mechanism 1 is attached to the step 4.
2 is provided with a buffer piece 14 at a horizontal movement position of the step 4 near the entrance of the escalator.
4 is held in the lowered position. For this reason, passengers getting on and off the escalator are not hindered from getting on and off by the buffer pieces 14 near the entrance. Then, at a position where the steps 4 are inclined to each other due to a step, the cushioning pieces 14 are arranged at positions higher than the upper surface of the steps 4, and the corners of the upper edge at the lower end side of the main frame 1 of the steps 4 are formed. 7 is disposed at a protruding position corresponding to the position 7.

Thus, in a state where a step is formed between the steps 4 when the steps 4 move on the inclined portion 3, the cushioning pieces cover the corners 7 formed at the lower end side edge of the main frame 1 of the steps 4. 14 are arranged. Therefore, even when a passenger who gets on and off the step 4 falls and hits the body at the corner 7, the shock is alleviated by the cushioning pieces 14, so that damage and pain caused by the fall are reduced. can do.

[0015]

As described above, the present invention provides a main frame having a plurality of main frames connected to a main frame having a horizontal portion formed at an upper end and a lower portion and a slant portion formed at an intermediate portion. A step that is disposed endlessly on the frame, moves horizontally in the horizontal portion of the main frame in a horizontal position, and moves in an inclined portion of the main frame while maintaining the horizontal position, and an upper end of the main frame provided on the step and having one side on the side A support is pivotally attached to the side of the step and extends to the lower end of the main frame of the step, a buffer piece attached to the pivotal end of the support, and an operating body attached to the lower side of the support. An operating mechanism, a horizontal guide provided on the main frame and arranged along the moving path of the steps, and a horizontal guide corresponding to the horizontal portion of the main frame and an inclined guide corresponding to the inclined portion of the main frame are formed, and the horizontal guide is provided. A position where the operating body is guided by the part and the buffer piece is lowered from the upper surface of the step Holding is obtained by providing a guide rail arranged in raised position than the step upper surface is raised guide buffers piece actuating member by the inclined guiding portion.

As a result, the step is equipped with the buffer piece via the operating mechanism, and the buffer piece is held at the lowered position at the horizontal movement position of the step near the entrance of the escalator. For this reason, the passenger getting on and off the escalator is not prevented from getting on and off by the buffer piece near the entrance. Then, at a position where the steps are inclined and move with a step between them, the buffer piece is arranged at a position higher than the upper surface of the steps, and the projecting position corresponding to the corner of the upper edge at the lower end side of the main frame of the steps. Placed in As a result, a step is generated between the steps when the steps move on the inclined portion, and the cushioning pieces are arranged so as to cover the corners formed at the edge on the lower end side of the main frame of the steps. For this reason, even if a situation occurs in which a passenger hitting the corners hits the corner when a passenger getting on and off the step falls,
The impact is alleviated by the shock-absorbing pieces, causing damage from falling,
It has the effect of reducing pain.
