(2) Step 30

Next, the steps 30 will be explained with reference to fig. 2. As shown in fig. 3, the step 30 includes a pair of right and

left step frames

303, 303 having a triangular shape, a reinforcement plate surface 304 formed on an upper surface of the step frame 303, and a riser surface 305 formed on a rear surface of the step frame 303, and the step frame 303, the reinforcement plate surface 304, and the riser surface 305 are integrally formed of an aluminum die-cast material.

As shown in fig. 4, the reinforcing plate surface 304 is provided with a peak portion 306 and a valley portion 307 extending in the front-rear direction, and when the step 30 moves into the access plate 34, the teeth 61 of the comb-teeth-shaped comb teeth 62 enter the valley portion 307 to discharge foreign matter placed on the reinforcing plate surface 304.

A projecting piece 70 for preventing the skirt of the longuette, the clothes of the passenger, from being sandwiched between the steps 30 and the skirt boards 44 is provided on the pair of right and left skirt boards 44. The projecting piece 70 will be described later.

(3) Tab 70

The projecting piece 70 will be described with reference to fig. 1 to 4. As shown in fig. 1, the projecting piece 70 is provided above the reinforcement plate surface 304 of the step 30 in a row from the landing hole on the lower layer to the landing hole on the upper layer on the pair of right and left skirt panels 44. The protruding piece 70 includes a base 72, caps 74 mounted on both end portions of the base 72, and guide portions 76 provided along the base 72.

The base portion 72 is a rectangular parallelepiped made of metal and long in the longitudinal direction, and is provided continuously from the entrance at the lower layer to the entrance at the upper layer along the front-rear direction of the skirt panel 44 and slightly above the reinforcement panel surface 304 of the step 30, as shown in fig. 2 and 3. As shown in fig. 2 to 4, the end of the lower stage of the base 72 is positioned above the comb teeth 62 provided at the tip of the lifting plate 34 of the lower stage, and the upper stage is similarly positioned above the comb teeth 60 of the lifting plate 32 of the upper stage. As shown in fig. 5, a groove 78 extending in the front-rear direction is provided on the step 30 side of the base 72.

The cap 74 is made of synthetic resin, and covers the end of the lower layer and the end of the upper layer of the base 72, respectively, as shown in fig. 2 to 4. The cap 74 is a triangular cone shape, and tapers toward the entrance side in the lower layer and widens linearly toward the base 72, and as shown in fig. 4, its angle in the planar shape is θ 1 °.

The plate-like guide portion 76 is made of synthetic resin and is engaged with the groove 78 of the base portion 72. The plate-like guide portion 76 protrudes from the base portion 72 toward the step 30 side, and is inclined downward from the position of the base portion 72 toward the reinforcement plate surface 304 of the step 30 as shown in fig. 5. As shown in fig. 4, the width gradually increases from the boundary position with the cap 74 (the position of the end of the lower layer of the base 72) toward the upper layer side continuously linearly at an angle θ 2 ° and then becomes constant. The angle θ 1 ° of the widened triangle has the following relationship with the angle θ 2 °:

0 DEG < theta 1 DEG < theta 2 DEG < 60 DEG, and theta 2 DEG-theta 1 DEG < 30 deg.

Thus, the projecting piece 70 is formed to be linearly widened from the tip of the cap 74 toward the base 72, and is further widened at the position of the guide portion 76.

(4) Effect

When a passenger wearing a longuette wants to ride the escalator 10 from the lower entrance, the skirt hem of the longuette is easily sandwiched between the steps 30 and the skirt panel 44. However, in the present embodiment, as shown in fig. 2 to 5, the projecting piece 70 is provided so as to cover the comb teeth 62 and the end of the reinforcement plate surface 304 of the step 30, and therefore is not sandwiched between the skirt panel 44 and the step 30.

As shown in fig. 4, even when the clothing of the passenger and the personal belongings are positioned at both ends of the step 30, the distal end of the cap 74 comes into contact with the distal end of the cap 74, and the distal end of the cap 74 gradually widens and continuously moves along the guide portion 76, so that the clothing and the personal belongings are not caught at the lower end of the projecting piece 70. In particular, since the angle of the cap 74 is θ 1 °, and the angle of the guide portion 76 is equal to or larger than θ 2 °, the clothing, the skirt, and the belongings of the passenger can be guided more smoothly.

(second embodiment)

Next, with reference to fig. 6, a projecting piece 70 of the escalator 10 according to the second embodiment will be described.

In the first embodiment, the guide portion 76 is a synthetic resin-made plate, but in the present embodiment, as shown in fig. 6, it is formed by bristles instead of bristles.

In the present embodiment, the clothing of the passenger, the skirt of the longuette, and the personal belongings that have moved along the angle θ 1 ° of the cap 74 also move along the guide portion 76 made of the brush bristles at the angle θ 2 °, and the clothing, the skirt, and the personal belongings are not caught.

(third embodiment)

Next, with reference to fig. 7, a projecting piece 70 of the escalator 10 according to the third embodiment will be described.

In the first embodiment, the cap 74 has a linear shape on the step 30 side, and the guide portion 76 formed of a synthetic resin plate has a linear shape at its widened portion. In the present embodiment, as shown in fig. 7, the curved line shape slightly protruding toward the step 30 side is formed instead. A groove 78 is also formed in the cap 74, and the leading end of the guide portion 76 formed of a synthetic resin plate is fitted into the groove 78 of the cap 74.

In the present embodiment, the passenger's clothes, skirt, and belongings are not caught.

(fourth embodiment)

Next, with reference to fig. 8, a projecting piece 70 of the escalator 10 according to the fourth embodiment will be described.

In the second embodiment, the cap 74 has a linear shape on the step 30 side, and the guide portion 76 formed of brush bristles has a linear shape in its widened portion. In the present embodiment, as shown in fig. 8, the curved line shape slightly protruding toward the step 30 side is formed instead. A groove 78 is also formed in the cap 74, and the tip of the guide portion 76 formed of brush is fitted into the groove 78 of the cap 74.

(modification example)

In the above embodiment, the cap 74 is made of synthetic resin, but may instead be made of metal.

In addition, although the base 72 is made of metal in the above embodiment, it may be made of synthetic resin instead.

In the above embodiment, the projecting piece 70 is provided continuously from the lower layer to the upper layer, but the projecting piece 70 of the lower layer and the projecting piece 70 of the upper layer may be provided separately instead.

Although the above embodiment has been described as being applied to the escalator 10, the present invention may be applied to a moving walkway instead.

Although one embodiment of the present invention has been described above, this embodiment is provided as an example, and is not intended to limit the scope of the present invention. These novel embodiments can be implemented in other various forms, and various omissions, substitutions, and changes can be made without departing from the spirit of the present invention. These embodiments and modifications are included in the scope and spirit of the present invention, and are included in the scope of the present invention and the equivalents thereof described in the claims.
