Description

  The present invention relates to a step of an escalator that does not cause injury even if a passenger accidentally falls.

  Conventionally, in the escalator step, if an elderly person accidentally falls on the step, the head etc. hits the acute angle part formed on the riser mounting side end of the step plate, causing bleeding or injury was there.

  Further, as a conventional technique, there is known an escalator in which a step having a thickness of about 2 mm is provided on a step plate and a riser at an acute angle portion of a step and a rubber protective cover having a thickness of 2 mm is attached (for example, see Non-Patent Document 1). ).

Japan Society for Invention and Innovation Open Technical Report No. 99-6611

  With conventional escalator steps, safety can be improved by attaching a rubber protective cover, but this is not perfect. Also, the role other than the protective cover could not be expected.

  The present invention has been made to solve the above-described problems. When the surface of the tread board is coming out of the boarding / exiting portion so that passengers can be put on the step, the shock absorber at the stepped acute angle portion protrudes upward by a spring force. In addition, the present invention provides an escalator step in which the cushioning material is pushed down by the comb teeth and retracted when the step enters the boarding / exiting portion.

  The step of the escalator according to the present invention includes a step board having a plurality of cleats and a riser, a plurality of cushioning materials provided between the cleats on the riser mounting side end of the tread board, and the tread board and the buffer. When the surface of the tread board is coming out of the boarding / exiting part to carry passengers, a plurality of cushioning materials are urged so as to protrude above the upper surface of the cleat, and the step is in the boarding / exiting part. When entering, it is provided with a biasing body that is pushed down by the comb teeth of the getting-on / off portion and receives a plurality of cushioning materials at the retracted positions between the cleats of the tread.

  In addition, the biasing body that projects the plurality of cushioning materials upward from the top surface of the cleat and that is received at the retracted position between the cleats of the tread plate projects by spring force.

  Further, the urging body for projecting the plurality of cushioning materials upward from the top surface of the cleat and receiving them at the retracted positions between the cleats of the treads is provided with end cams provided at both ends of the plurality of cushioning materials, The connecting member for connecting the cushioning material and the end operation cam, and a spring provided between the connecting member and the tread.

  Further, the spring provided between the connecting body and the tread is inclined in an oblique direction.

  According to the present invention, when the surface of the tread board comes out of the boarding / alighting part in order to put passengers on the step, the shock absorber of the step acute angle part formed at the riser mounting side end of the tread board protrudes upward by the spring force. Therefore, even if an elderly person or the like accidentally falls on the step and hits the head, the shock can be reduced by the cushioning material, and bleeding and injury can be eliminated. Further, when the step enters the boarding / exiting section after the passenger gets off, the cushioning material is pushed down by the comb teeth and retracted, so there is no problem in the operation of the escalator. Further, since the cushioning material protrudes above the upper surface of the cleat at the riser mounting side end of the tread board, there is an effect that passenger's belongings, such as a trunk, do not fall.

Embodiment 1 FIG.
1 is a front view showing a schematic configuration of an escalator step in Embodiment 1 of the present invention, FIG. 2 is a side sectional view of the same, and FIG. 3 shows a main configuration of the escalator step in Embodiment 1 of the present invention. FIG. 4 is a side sectional view showing a state immediately before the cushioning material of the escalator step in the first embodiment of the present invention is pulled down by being pushed down by the comb teeth of the boarding / exiting portion.

  In the figure, 1 is an escalator step, 2 is a tread plate, 3 is a riser, 4 is a follower roller, 5 is a cleat provided on the tread plate 2, and 6 is provided between the cleats 5 at the end of the tread plate 2 on the riser mounting side. When the surface of the tread plate 2 comes out of the boarding / exiting part for carrying a passenger during normal operation, it protrudes above the upper surface of the cleat 5 so that the passenger When the step 1 enters the boarding / exiting section after getting off, the cushioning material 6 is retracted by being pushed down by the comb teeth. 7 is an end operation cam provided at both end portions of the cushioning material 6, 8 is a coupling body in which a large number of cushioning materials 6 are fixed through and both ends are connected and fixed to the end motion cam 7, and 9 With springs provided at both ends of the riser mounting side end of the step 1, when the surface of the step board 2 comes out of the boarding / exiting part for carrying a passenger during normal operation, the cushioning material 6 is cleat 5 by the spring force. It is energized so as to protrude upward. The end portion operation cam 7, the coupling body 8, and the spring 9 constitute an urging body that urges the plurality of disk-shaped cushioning materials 6 so as to protrude above the cleat 5 by a spring force. Reference numeral 10 denotes comb teeth provided on the escalator getting on / off portion. When the step 1 enters the getting on / off portion after the passenger gets off, the cushioning material 6 resists the spring force as shown by an arrow in FIG. It is pushed down by 10 and retracts.

  According to the first embodiment, when the surface of the tread board is coming out of the boarding / exiting portion for carrying passengers, the shock absorber at the stepped acute angle portion formed at the riser mounting side end of the tread plate protrudes upward by the spring force. Therefore, even if an elderly person falls accidentally on the step and hits the head, the shock can be reduced by the cushioning material, and bleeding and injury can be eliminated. Further, when the step enters the boarding / exiting section after the passenger gets off, the cushioning material is pushed down by the comb teeth and retracted, so there is no problem in the operation of the escalator. Further, since the cushioning material protrudes above the top surface of the cleat at the riser mounting side end of the tread board, there is no possibility that passenger's belongings, such as trunks, will fall over the cushioning material.
