Description

Escalator step and escalator with it {ESCALATOR STEP AND ESCALATOR FITTED WITH THE SAME}

TECHNICAL FIELD The present invention relates to a step of an escalator made of a resin and having a light transmissive riser, and an escalator to which the step is mounted.

In the steps of the conventional escalator, the riser corresponding to the height of the step of the passenger and the stairs is cast-molded with aluminum die casting, and the surface is painted and colored. In such a step, the cleat portion of the scaffold or riser is worn out by long-term use, and there is a problem that the surface coating is peeled off.

On the other hand, the step of the escalator provided with the scaffold made of resin is also proposed. Since the scaffold made of resin can be colored with the resin material itself and can be colored relatively freely, there is an advantage that there is no discoloration or deterioration of design even after long-term use. In addition, by using the scaffold made of resin, there are advantages in that various features such as smooth riding comfort (tread) and weight reduction, which are not obtained in the scaffold made of aluminum die casting, can be obtained.

In addition, as a conventional technique in which a part of the riser is made of resin among the steps of the escalator, a metal support plate is formed so as to close the opening from the rear surface side of the riser after removing the central portion of the riser, which has been cast and formed by aluminum die casting. And fixing the cover display means and the cover plate which has a translucent property to this support plate are proposed (for example, refer patent document 1).

Next, the specific assembly procedure of step 12 which has the said structure is demonstrated. 9 and 10 are side views for explaining the assembling procedure of the steps of the escalator in the first embodiment of the present invention. 9 and 10, in the assembly of the step 12, first, the footrest 17 is fastened and fixed by bolts 25 to the upper mounting surface 18a of both brackets 18 arranged at predetermined intervals. do. At this time, the lower side 28a of the upper reinforcing material 28 between the mounting portion 17a of the footrest 17 on which the bolt 25 is screwed is formed and the upper mounting surface 18a of each bracket 18. The upper side of the side reinforcement 30 and the upper side 31a of the side reinforcement 31 are fastened to the bolt 25, and the upper reinforcement 28 and each upper end of side reinforcement 30 and 31 are fixed.

Here, the upper reinforcing member 28 having a small width in the vertical direction of the portion facing the riser 19 is mounted to the bracket 18 only by fixing the lower side 28a. In addition, the upper reinforcing material 28 shown in FIG. 9 is bent toward the side of the upper riser half riser 19 to secure a predetermined strength and rigidity. On the other hand, in the side reinforcing member 31 having a large width in the vertical direction of the portion facing the riser 19, the recess 31b provided at the lower end thereof is fastened and fixed to the bracket 18 on the other side by the bolt 35. Similarly, the concave portion of the lower end of the side reinforcement 30 is fixed to the bracket 18 on one side by the bolt 34.

In addition, the lower reinforcement member 29 has both ends thereof fastened and fixed to both brackets 18 by bolts 33, and the side reinforcement member 31 of which the other end of the upper side 29a bent toward the half riser 19 is disposed to face each other. It is fastened and fixed by the bolt 37 to the lower side 31c. In addition, in order to improve workability, the mounting nut 29b may be fixed to the other end of the upper side 29a of the lower reinforcing material 29 in advance. In addition, one end of the upper side 29a is fastened and fixed to the lower side of the side reinforcement 30 disposed to face each other by bolts 36. In the assembled state as described above, the footrest 17, the upper reinforcement 28, and the lower reinforcement 29 are connected between the two brackets 18 disposed on the left and right, and are firmly integrated. Further, in the assembled state, an opening 32 having a rectangular shape with an edge around each of the reinforcing materials 28 to 31 is formed.

Next, as shown in FIG. 10, after attaching the display body 38 to the predetermined position of the back surface of the riser 19, the riser 19 is fixed to the metal reinforcement member 20. Next, as shown in FIG. In addition, for fixing the riser 19 to the metal reinforcement member 20, for example, the countersunk screws 39, 40, and 41 are provided from the upper reinforcement 28 and the lower reinforcement (from the surface 26 side of the riser 19). 29) and fasten to side reinforcements 30 and 31 respectively.

According to the first embodiment of the present invention, since the surface 26 side of the riser 19 is made of light-transmitting FRP, high designability can be given to the riser 19. For this reason, the riser 19 itself becomes a display means, for example, the display body 38 does not use the display body 38 other than displaying advertisements, such as an in-store guide and a logo mark. Even if the escalator is harmonized with the architecture, it can play a role as a part of the interior, or it can be used for various purposes such as using the foot as a warning means for the safe use of the escalator. Moreover, since the whole surface 26 of the riser 19 is comprised by FRP also compared with the conventional thing, there exists an advantage that there is no fear of discoloration and design deterioration even when using for a long time.

In addition, the riser portion is required to have predetermined strength and rigidity, and when all of them are made of FRP, it is necessary to make the thickness very large, resulting in high cost and difficulty in realizing stability of dimensional accuracy. However, in Example 1, since the metal reinforcement member 20 is provided between the bracket 18 arrange | positioned at the left and right, and the riser 19 made of FRP is being fixed to this metal reinforcement member 20, The riser 19 can be constituted by a thin plate-like member, whereby the production efficiency can be improved and the cost can be realized. In particular, the metal reinforcing member 20 is disposed opposite the upper and lower edges of the rear surface of the riser 19, or disposed opposite the edge of the rear surface of the riser 19, thereby providing a predetermined strength and It is possible to secure rigidity. In addition, as described above, in addition to the fastening and fixing of screws, bolts, and the like, the fixing of each component can be used to secure the reliability of the step 12 by using an adhesive together.

In addition, unlike the step surface 23 of the footrest 17 which the passenger always presses on the riser 19, high friction resistance is not required. In addition, since it does not correspond to a part where the passenger climbs, the performance of preventing slip required on the tread surface 23 of the footrest 17 is also not required, and on the contrary, it is prevented from being sandwiched between the steps 12. From this, a low coefficient of friction is required. Therefore, the FPR material of the riser 19 does not need to be subjected to improvement of abrasion resistance or surface coating to obtain a high friction coefficient. If only the riser 19 is FRP, weight reduction and designability can be achieved without waste. Become.

In addition, when employ | adopting the step 12 of the said structure for an escalator, all the steps are made into the step 12 of the said structure, for example, a part is made into the step 12 of the said structure, and another step May be provided with a riser made of aluminum die casting as in the prior art. Moreover, even when the step 12 of the said structure is employ | adopted for all the steps, by attaching the display body 38 which does not have translucency to the one part to the back surface of the riser 19, what kind of display is given only to some steps, etc. Any correspondence is possible.

As mentioned above, according to the escalator apparatus which concerns on this invention, by using the FRP riser which has a predetermined light transmittance at the step of an escalator, it can be used for various uses, making a riser original designability.

In addition, by supporting the riser made of FPR to the brackets on both sides through the metal reinforcing member, the predetermined strength and rigidity can be secured, and the riser is formed in a thin state to improve production efficiency and reduce cost. It can be realized.
