  The escalator of embodiment is demonstrated based on drawing. In the following text, front, rear, left and right are expressions when the upper floor is viewed from the lower floor. Here, the front means the lower floor side.

(Escalator structure)
FIG. 1 is a cross-sectional view of an escalator 2 according to this embodiment. Trusses 20 are installed on the upper and lower floors of the building. Sprockets 21 and 22 are arranged inside the upper floor side and the lower floor side of the truss 20, respectively. An endless chain 23 is wound around the sprockets 21 and 22. One of the sprockets 21 and 22 is connected to a driving device 24 having a motor and a speed reducer, and rotates by driving of the driving device 24. This rotation drives the chain 23 and the other sprocket. Steps 1 are connected to the chain 23 at equal intervals with no gaps. When the chain 23 is driven, the step 1 connected thereto is circulated between the upper floor side and the lower floor side along a guide rail (not shown).

(Structure of escalator step 1)
Steps 1 of the escalator 2 according to this embodiment are shown in FIGS. The framework of the step 1 is formed by a frame 10. The frame 10 includes side plates 11 disposed on the left and right sides of the step 1, a coupling portion (not shown) that couples the left and right side plates 11, and an upper plate 12 that is disposed across the upper portions of the left and right side plates 11. The upper plate 12 is provided at three locations in the front-rear direction.

  At the front and rear of the lower portions of the left and right side plates 11, wheels 13 are provided that rotate along the guide rail when the step 1 moves. In addition, a riser 14 is provided at the front portion of the left and right side plates 11 and serves as the upper part of the step 1. A cleat 15 is provided on the upper surface of the upper plate 12.

  The upper plate 12 is a rectangular member in a plan view having a width slightly wider than the interval between the left and right side plates 11. The left and right end portions of the upper plate 12 are made one step lower than the central portion 18, and the side wall 4 and the upper plate end portion 40 of the step portion are formed.

  As shown in FIG. 4, the cleat 15 is a corrugated stainless steel plate. The wavy peak is extended in the front-rear direction of the cleat 15. The length of the cleat 15 in the front-rear direction coincides with the length of the upper plate 12 in the front-rear direction, and the length of the cleat 15 in the left-right direction coincides with the length of the central portion 18 of the upper plate 12 in the left-right direction. The cleat 15 is attached to the upper plate 12 by fixing the lower surface of the cleat 15 and the upper surface of the upper plate 12 by spot welding. Reference numeral 16 in FIG. 4 denotes a welded portion.

  At the center of the cleat 15 in the front-rear direction, a wavy peak of the cleat 15 is cut out in the left-right direction to form a groove 17. The groove 17 is linearly extended to both ends of the cleat 15. The cleat fixture 3 is disposed in the groove 17. The cleat fixture 3 includes a rod-like main body 30 having the same length as the groove 17 and a fixing portion 31 formed by bending both ends of the main body 30 at a right angle. The main body 30 of the cleat fixing tool 3 is disposed at the groove bottom of the groove 17, and the fixing part 31 is bent downward along the side wall 4 outside the both ends of the cleat 15 of the groove 17. The fixing portion 31 is fixed to the side wall 4 with bolts 32 from the outside. Accordingly, the cleat 15 is fixed to the upper plate 12 of the frame 10 by the cleat fixing tool 3.

  A demarcation cleat 33 is fixedly disposed on the upper plate end 40 on the outer side of the bolt 32 in the left-right direction. The distance between the head of the bolt 32 and the inner end face of the demarcation cleat 33 is shorter than the length of the threaded portion of the bolt 32. The color of the cleat 15 is black, and the color of the demarcation cleat 33 is yellow.

(effect)
In the escalator step 1 of the embodiment, since the cleat 15 is fixed to the upper plate 12 of the frame 10 by the cleat fixture 3, the cleat 15 does not rise even if the weld between the cleat 15 and the upper plate 12 is peeled off. Therefore, it does not cause problems such as poor ride comfort and problems caused by cleats hitting the comb.

  In particular, since the cleat fixture 3 is provided in the center of the cleat 15 in the front-rear direction, it is possible to prevent the front and rear of the cleat 15 from partially rising.

  Here, the demarcation cleat 33 is disposed outside the bolt 32, and the distance between the head of the bolt 32 and the inner end face of the demarcation cleat 33 is shorter than the length of the threaded portion of the bolt 32, so that the bolt falls off. There is no. Therefore, the cleat fixture 3 does not come off.

(Example of change)
The upper portion of the cleat fixture may be waved with ridges formed at the same intervals as the cleat 15. In this case, the peak portion of the cleat fixture and the peak portion of the cleat 15 are made to coincide with each other in the front-rear direction.

  Thereby, it is possible to prevent the foot from being caught in the groove 17 of the cleat 15.

  When the upper part of the cleat fixture is corrugated, it is desirable that the upper end of the peak part slightly protrudes from the upper end of the corrugated peak part of the cleat 15. The protruding height is desirably 1 mm or less in order to prevent the foot from being caught.

  As a result, the upper end of the cleat fixture plays a role of preventing the slipping of the foot.

  In the case where the upper portion of the cleat fixing tool is corrugated, the material of at least the mountain portion of the cleat fixing tool may be made of non-slip material such as rubber.

  As a result, the upper end of the cleat fixture plays a role of preventing the slipping of the foot.

  The cleat fixture may be provided at a place other than the center in the front-rear direction of the cleat. For example, it may be provided on the side of the step corner in the front-rear direction of the cleat.

  If the top of the cleat fixture is corrugated and its upper end protrudes from the upper end of the cleat or is made of a non-slip material, the cleat fixture must be provided on the side of the step corner in the longitudinal direction of the cleat. , Play the role of anti-slip of the foot.

  The cleat may be fixed to the frame by a plurality of cleat fixtures.

  If the cleat is fixed to the frame by a plurality of cleat fixtures, the cleat is more difficult to lift.

  The cleat and the upper plate of the frame may be fixed by a method other than spot welding. For example, it may be fixed with an adhesive. The cleat and the upper plate of the frame may be fixed only by the cleat fixing tool without being fixed.

  The cleat fixture may be fixed to the frame by means other than bolts. For example, a claw protruding toward the upper plate central portion 18 is formed at the tip of the fixing portion of the cleat fixing tool, a hooking hole is formed in the side surface 19 of the upper plate central portion 18, and the claw is engaged with the hooking hole. By doing so, the cleat fixture may be fixed to the frame. Further, the cleat fixture may be fixed to the frame with an adhesive. Moreover, you may use an adhesive agent and another fixing means together.

  The cleat fixture may be a different color than the cleat.

  Thereby, a user can be made to feel beauty through vision.

  In the case where irregularities different from the corrugated shape of the above-described embodiment are formed on the top surface of the cleat, it is desirable that irregularities that coincide with the irregularities are also formed on the cleat fixture.

  Thereby, it is possible to prevent the foot from being caught in the cleat fixing tool or the groove of the cleat.

  The steps of the above embodiment can also be used for moving walkways.

  The above embodiment is an illustration and the scope of the invention is not limited to this. The above embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the scope of the invention. The above embodiments and modifications thereof are included in the inventions described in the claims and their equivalents.
