The present invention relates to a staircase of an escalator.

14 to 20 show, for example, the steps of the escalator 1 shown as a conventional example in Japanese Patent Laid-Open No. 57-137282 (USP 4,483,432).

In FIG. 14, (1) is an escalator, (2) is a staircase for carrying and carrying passengers, and several staircases (2) are constantly connected by a link. Run in parallel with each other, and the adjacent step (2) becomes horizontal in both end sections C close to the platform 3, and in step B in which the inclination angle between the intermediate section A and both end sections C is changed, Drive while changing

The stairs 2 will be described in detail with reference to FIGS. 15 to 20. In these drawings, reference numeral 4 denotes a passenger board, and several cleats 41 and grooves 42 are alternately provided on the upper surface of the board 4. (5) is a curved part arranged in substantially L shape at the back end of the answer board 4, and several cleats 51 and the groove | channel 52 are provided in the convex surface of the curved part 5.

The cleat 41 of the answer plate 4 has a front end portion 411 every other line and protrudes by a length L, and the rear end 412 of the cleat 41 from which the front end portion 411 protrudes is a groove of the curved portion 5 ( 52, the rear end portion 414 of the cleat 41, which is uniformly drawn to the bottom surface of the length L, and the front end 413 does not protrude, is adjacent to the height L of the cleat 51 of the curved portion 5 ( 42 and protrude as much as the width T, and the curved portion 5 has a cleat 51 and a rear end 412 having the same width as that of the cleat 41 of the answer board 4 on which the rear end 414 protrudes. The grooves 52 having the same width as that of the cleats 41 not provided are provided, and the pitch P ₂ of the cleats 51 and the grooves 52 is twice the pitch P ₁ of the cleats 41 of the answer board 4. The width (length) T ₂ of the cleats 51 is configured to be about 3.5 times smaller than the width T ₁ of the cleats 41 of the answer board 4.

(6) is a bracket for integrally coupling the plate (4) and the bent portion (5), (7) is a roller mounted to the bracket (6) via the shaft (8), the shaft (8) is coupled to the link As a result, the roller 7 is guided to the guide rail so that the stairs 2 run.

When the stairs 2 configured as described above are driven in the direction of the arrow of FIG. 14 by driving the escalator 1 up, the stairs 2 adjacent to the one before passing the section B between the intermediate section A and both end sections C are provided. With respect to the stepped step, the relative position changes horizontally as indicated by E → F → G in FIG.

In the stairs of the conventional escalator as described above, as shown in FIG. 20, the passenger on the answering plate 4 pushes the toe 91 of his shoe 9 against the cleat 51 of the curved portion 5. In particular, when the shoe 9 has a large coefficient of friction such as rubber shoes, the toe 91 is bent downward by the frictional force, and the stepboard 4 is moved while the stairs 2 are moved horizontally from the stepped state. The cleat 41 of the cleat 41 and the engaging part of the cleat 51 of the curved part 5 may be clamped, and the engaging part of both cleats 41 and 51 may be made when the answer board 4 becomes horizontal in a stepped state. Since it is constant until the shoe (9) once tightened, it is difficult to remove, entering the platform (3) there was a problem that leads to human accidents.

In addition, since the front end portion 411 of the cleat 41 of the plate 4 protrudes only one line in the stairs of the conventional escalator as described above, the interval S in the step width direction between the protruding front end portions 411 is There was a problem in that foreign matter such as the tip of the passenger's shoes, the tip of the umbrella or dust was caught.

If all the front ends of the cleats of the answer boards are projected with the same width, the cleats are usually formed integrally by the answer boards and the bent parts, respectively, with the casting of the metal, so that casting becomes difficult.

That is, the gap between the front end of the cleat protruding from the answer board and the cleat width direction of the cleat of the curved part needs to secure a predetermined dimension in order to prevent contact due to the shaking of the running of the stairway, and the front end from which the cleat of the answer board protrudes. If the width of the part is to be the same and the gap of the predetermined dimension is to be secured, the cleat of the bent portion must be molded to a width narrower than the minimum thickness necessary for casting, and casting becomes difficult.

The present invention solves the problem described above, even if the front end portion of the foot of the passenger's shoes, etc. is tightened when the stepped state of the cleat of the answer plate and the cleat of the bent portion in the stair state, whether the horizontal portion of the cleat is naturally removed from the engaging portion of both cleats An object of the present invention is to provide a safe escalator stairway by easily pulling out with a slight force.

In addition, an object of the present invention is to provide an escalator staircase that solves the above-mentioned problems and is difficult to fit into shoes and foreign objects of passengers and has high safety and is suitable for mass production.

The present invention is a step of an escalator having an answer plate provided with alternating cleats and grooves on the upper surface and a curved portion provided with alternating cleats and grooves on the convex surface, the protrusion of the cleats provided on the answer plate of one adjacent step Cleats provided at one end and at the bend of the other step are deeply engaged when stepped, and are shallowly engaged as they are lined up side by side in a horizontal state.

In the present invention, since the configuration as described above, even when the adjacent staircase is in a staircase state, even if the toe of the shoe, such as a rubber shoe of the passenger, is tightened into the engaging portion of the cleat of the answer plate and the cleat of the bent portion, the engagement depth of the two cleats is in the step state In the horizontal part, the toe of the shoe is naturally pulled out of the engaging part of both cleats, or with a slight force, so that the toe is stuck into the platform with the toe being tightened. can do.

Embodiments of the present invention will be described below with reference to FIGS.

1 to 5 show one embodiment of the present invention, in which the same reference numerals as those of FIGS. 15 to 20 denote the same or corresponding parts.

In this embodiment step (2) by varying the curvature of the cleat 51 and the groove 52 of the curved portion 5, the height of the cleat 51 and the depth dimension of the groove 52, the opposite side plate 4 Gradually become smaller as it is turned toward the opposite side, and the engaging portion α of the protruding front end portion 411 of the cleat 41 provided on the cleat 51 and the step plate 4 of the staircase 2 adjacent to the rear of the staircase 2 Is deep when the staircase is in a staircase, and is shallow as the level becomes horizontal, and the overlapping portion β of the front end of the grooves 42 of the cleats 51 and the plate 4 also becomes a lot when the staircase is in the horizontal state. I'm doing less.

Further, by forming irregularities alternately in the width direction of the staircase 2 in the curved portion 5, the deep groove 521 to which the protruding front end portion 411 of the cleat 41 of the answer board 4 engages. And shallow grooves 522 are alternately formed at pitches P ₃ and P ₄ , and the cleats 41 of the plate 4 are opposed to the grooves 521, 522, respectively, and the pitch P ₃ is greater than P ₄ . It's loud.

Incidentally, the configuration other than the above described in this embodiment is the same as the conventional one shown in Figs.

Since the staircase of this embodiment is configured as described above, when the adjacent staircase 2 is in the staircase state as shown in FIG. 1D, the groove 42 of the step plate 4 of the one staircase 2 Since the portion β overlapping the cleat 51 of the curved portion 5 of the other staircase 2 located in front is large, the toe 91 of the shoe 9 such as the rubber shoes of the passenger on the answer board 4 is the answer plate. It becomes difficult to reach to the space | interval of the cleat 41 of (4) and the cleat 51 of the curved part 5, and it becomes difficult to toe the toe 91 to the engaging part of the cleats 41 and 51. FIG.

In this embodiment, even if the toe 91 of the shoe 9 is tightened to the engaging portions of the cleats 41 and 51, for example, the engaging portions α of FIG. As indicated by E → F → G, as the horizontal state becomes shallow, the toe 91 is naturally pulled out of the engaging portion or easily pulled out with a slight force in the horizontal portion.

In addition, since it is made integrally by casting of a normal curved portion, and the height of the cleats is high, it is necessary to secure the gap between the front end portions of the cleats, so that the inclination of the cleats becomes sharp and the consumption of casting is severe. Although unsuitable for mass production, in this embodiment, the pitches of the grooves 52 and the cleats 51 of the curved portions 5 alternately vary, so that the front end portions 411 of the cleats 41 of the answer board 4 protrude. The groove 521 to be engaged has a large pitch P ₃ , and a portion of the groove 522 to which the front end 413 of the cleat 41 of the answer board 4 does not fit is formed at the front end of the cleat 51. It is shallower than the depth of 522, so that the subtraction inclination can be made gentle. Therefore, the embodiment of this embodiment consumes less mold when casting the curved portion 5, and is suitable for mass production.

In addition, in the above embodiment, the cleats 41 and the grooves 42 of the answer board 4 and the cleats 51 and the grooves 52 of the bent portion 5 are illustrated with pure materials. As shown in FIG. 7 and the cleats 41 and the grooves 42 of the plate 4 and the cleats 51 and the grooves 52 of the curved portions 5 may be formed using a press-formed thin steel sheet. good.

As described above, in the present invention, in the staircase of an escalator having an answer plate having several cleats and grooves alternately provided on the upper surface and a curved portion having several cleats and grooves alternately provided on the convex surface, When the cleats provided in the front end of the cleats protruding from the curvature of the other stairs are deeply and horizontally engaged when they are in a staircase state, the end portions of the toes of the passenger's shoes, such as the tip of the passenger's shoe, Even when tightened in the stepped state with the engaging part, the horizontal part can be easily pulled out by the natural or slight force from the engaging part of both cleats, thus providing a safe escalator stairway without entering the platform with shoes attached. The effect is that you can.

In the embodiments of FIGS. 8 to 12 of the present invention, irregularities are alternately formed in the curved portion 5 in the width direction of the stairs 2, so that the width is wide and the depth groove 521 and the width are narrow. The shallow grooves 522 are alternately formed, and the front end portion 411 and the front end portion 411, which protrude from the front end portion 411 and the front end portion 413, which are wide and long, protrude in the cleats 41 of the answer board 4, as in the prior art. The portions 415 are alternately formed, and the pitch P ₃ of the cleats 41 is made larger than P ₄ .

Then, the front end portion 411 of the cleat 41 provided in the step plate 4 of the adjacent step is wide and protrudes in the groove 521 having a wide and deep groove of the curved portion 5, and the width of the cleat 41. These narrow and short protruding front ends 415 are engaged with the narrow and shallow grooves 522 at intervals, respectively.

The configuration other than the above-described configuration of this embodiment is the same as the conventional one shown in FIGS.

In this embodiment, the front end portion 411 of the cleat 41 of the answer plate 4 has a wide and protruding front end portion 411 in the wide and deep groove 521 of the curved portion 5, and the width of the cleat 41 is short and short. Since the protruding front end portions 415 are alternately arranged by engaging each of the narrow and shallow grooves 521, the cleats 41 of the answer board 4 are the front end portions 411 protruding over the entire step width direction. Since the 415 is provided, the interval in the step width direction between these ends becomes small, and foreign matters such as toe of the passenger's shoes, the tip of the umbrella, dust, etc. are difficult to fit in the gap.

In addition, since the step plate and the curved part of a normal staircase are made integrally by casting, and when the height of a cleat is high, since the clearance of the cleat of a staircase and the cleat of a curved part needs to be ensured to a predetermined dimension, the inclination of the cleat is Although there is a point that the consumption of casting is severe and is unsuitable for mass production, in this embodiment, the pitches of the grooves 521, 522 and the cleats 51 of the curved portion 5 are alternately different, and thus the answer board 4 is used. The width of the groove 521 is wide, the front end portion 411 protruding long and wide, the width of the groove 522 is small, the front end portion 415 protruding short width of the answer plate 4 is narrow Since it is shallow, the subtraction inclination can be made gentle and the casting consumes little when cast.

In addition, since the cleat 41 of the answer board 4 of this embodiment alternately arranges the front end portion 411 which is wide and protrudes long and the front end portion 415 which is narrow and short protrudes, the short front end has a wide width. Even if it is narrow, the minimum thickness required for casting may be thin, so that the minimum thickness required can be maintained, so that the casting can be easily performed and the productivity is good.

Therefore, this embodiment is suitable for mass production.

In the present invention, as shown in FIG. 13, the short protruding front end portion 415 of the cleat 41 of the answering plate 4 may be formed in a substantially thin front plane.

Incidentally, in the above embodiment, the cleats 41 and the grooves 42 of the plate 4 and the cleats 51 and the grooves 52 of the curved portions 5 are made of pure material. As shown in FIG. 8, the cleat 41 and the groove | channel 42 of the answer board 4, and the cleat 51 and the groove | channel 52 of the curved part 5 may use the press-formed workpiece of a thin steel plate. .

Moreover, this invention is applicable also to the thing whose height of the cleat of a curved part is the same from the opposite end side of an answer board side.

As described above, the present invention is a step of the escalator provided with the answer plate provided with alternating cleats and grooves on the upper surface and the curved portion provided with alternating cleats and grooves on the convex surface, the width of the cleats of the answer plate is wide The long protruding front part is placed in the wide and deep groove of the curved part, and the short and short protruding front part of the cleat is placed in the narrow and shallow groove, respectively. The shape makes it difficult to pinch shoes, foreign objects, etc., and thus has high safety, high productivity, and is suitable for mass production, thereby providing an inexpensive escalator stairs.
