Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an escalator installed at an angle between each floor of a high-rise building, and in particular, to a riser of a moving step in this escalator. Concerning improvements to the main body.

(Prior art) Conventionally, the moving steps in this type of escalator were
It is constructed as shown in FIGS. 7 to 7.

That is, in FIGS. 4 to 7, a large number of movable steps 2 are provided on a loop-shaped rail 1 that is installed at an angle between each floor of a high-rise building so that it can be raised and lowered by a drive chain (not shown). Each movable step 2 has a pair of rollers 4a and 4b rotatably mounted at the front and rear of the lower part of the step frame 3, and a tread 5 is laid horizontally on the upper part of the step frame 3. A riser main body 6 provided with an arc-shaped create 6a on the step frame 3 located at the rear end of the step frame 3 is configured to mesh with an edge of the create 5a of the other step board 5.

In particular, the riser main body 6 has an uneven create 6a formed on its surface, and reinforcing ribs 6b formed on its back surface, and the riser main body 6 has its respective ears 6c and support parts 6d to support the steps. It is attached to frame 3.

Therefore, during operation of the escalator described above, as shown in FIG. A relative movement is generated between the movable steps 2 and the create 6a of the board 6, and each adjacent movable step 2 near the entrance changes from a stairway state to a substantially horizontal state, thereby facilitating the boarding and alighting operations of passengers.

(Problems to be Solved by the Invention) However, during operation of the above-mentioned escalator, as shown in FIG. and create 6 of the tread plate 5 and the riser body 6.
When the adjacent movable steps 2 in the vicinity of the entrance/exit change from a stairway state to a substantially horizontal state due to a relative movement between There is a risk that the user may be caught between the create 6a of No. 6 and the footboard 5. In particular, the child's rubber shoes S on the treadle 5 and the vinyl tip Sl are attached to the riser body 6.
There is a risk that the user may be caught between the create 6a and the footboard 5.

On the other hand, if lit smoke moss is caught between the create 6a of the riser main body 6 and the step board 5, the create 6 of the riser main body 6 made of synthetic resin, for example,
(a) not only causes thermal deformation, but also damages the engagement between the edge of the create 5a of the step board 5 and the create 6a of the riser body 6, which may cause galling or noise.

The present invention was made in view of the above-mentioned circumstances, and involves heating and pasting a film made of a heat-resistant polymer material on the surface of the create of the riser body to prevent the generation of static electricity and thermal deformation. To provide an elevator that prevents children's rubber shoes and vinyl tips on the tread from being caught between the riser main body's create and the tread, and improves passenger safety. The purpose is to

[Structure of the invention]

(Means for solving the problems and their effects) The present invention includes:
The cleat on the riser body is formed into a rough surface, and a polymeric film that is integrated with the aluminum sheet is heated and attached to this rough surface to prevent static electricity generation and thermal deformation. This prevents the tip of the rubber shoe or vinyl from being caught between the riser body's create and the treadle, and improves passenger safety.

(Example) Hereinafter, the present invention will be described with reference to an illustrated embodiment.

Note that the present invention includes the same constituent members as those in the above-mentioned specific example.
The same reference numerals will be used for explanation.

In FIGS. 1 to 3, reference numeral 6 denotes a riser body made of, for example, a synthetic resin material, and this riser body 6 has a create 6a with an uneven surface formed thereon. A reinforcing rib 6b is formed on the back surface, and the riser main body 6 is attached to the step frame 3 by each lug 6C and a support part 6d formed on a part of the riser main body 6. In particular, the create 6a, which has irregularities formed on the surface of the riser main body 6, forms a rough surface with fine irregularities, as shown enlarged in FIGS. 2 and 3. For example, a film 7 formed integrally with each polymeric material 7a such as a polyethylene film and an aluminum sheet 7b may be used on the rough surface with unevenness.
The surface of this film 7 prevents the generation of static electricity and thermal deformation, and protects the top end S1 of the children's rubber shoes S and vinyl shoes S on the treadboard 5 from the riser body. It is designed to have a low friction surface so as not to be pinched between the treadle 5 and the treadle 5, and to improve passenger safety.

Therefore, during operation, the present invention, as shown in FIG.
During the process in which the adjacent movable steps 2 in the vicinity of the entrance/exit change from a staircase state to a substantially horizontal state, a relative movement is caused between the step board 5 and the film 7 integrated with the create 6a of the riser body 6. As a result, the adjacent moving steps 2 near the entrance and exit change from a stairway state to a substantially horizontal state. Even if the tip end Sl is in contact with the film 7 that is integrated with the create 6a of the riser main body 6, this film 7 forms a low friction surface, so that it does not get caught between the riser body 6 and the tread plate 5. In addition to improving the safety of passengers, even if a lit cigarette is caught between the create 6a and the footboard 5, the film 7 integrated with the create 6a will not be exposed to heat. There is no risk of physical deformation.

〔Effect of the invention〕

As described above, according to the present invention, the cleat 6a of the riser body 6 is formed to have a rough surface, and the aluminum sheet 7 is formed on this rough surface.
Since the film 7 made of polymeric material 7a, which is integrated with the riser 7 body 6, is applied by heating, it prevents the generation of static electricity and thermal deformation, and prevents the tip of the passenger's rubber shoes on the tread. This has excellent effects such as preventing the passenger from being caught between the create 6a and the step board 5, and improving passenger safety.
