DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an escalator tread placed on an existing staircase.

[0002]

2. Description of the Related Art There is an escalator which is mounted on an existing stair and fixed and installed with concrete bolts or the like without performing a large-scale construction. Such an escalator is often installed on, for example, a stair at a station or the like because of its easy installation.

[0003] Also, on the mounting surface of the escalator tread,
It is formed in a comb-like shape by a plurality of ridges extending along the running direction and spaced from each other. The comb teeth serve as a non-slip function, and rain water and the like are guided by the concave grooves of the comb teeth, thereby preventing rain water from collecting over the upper surface of the tread plate.

[0004]

However, in the case of an escalator installed on a platform of a station, for example, when rain starts, water drops from umbrellas of many commuters cause the treads on the downstairs side to have comb teeth. There is a case where water overflows over the concave groove and rainwater collects on the upper surface of the tread. The footboard is made of aluminum die-cast or stainless steel, the ridge extends in the running direction, and the surface is smooth, so when the rider applies force to the footboard to transfer from the footboard to the floor, the surface becomes There is a problem that when wet, it becomes easy to slide along the ridge.

[0005] When the escalator is installed on the platform, rain or the like may fall directly on the escalator depending on the location, and this makes it easier for rainwater to collect.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an escalator tread that does not slip under the foot even during rain.

[0007]

[0009]

SUMMARY OF THE INVENTION The present invention is directed to an escalator mounted on a staircase and extending along a traveling direction and arranged at intervals in a width direction perpendicular to the traveling direction. In the escalator tread having ridges,
The inner surface of the concave groove between the ridges is a escalator tread plate that is subjected to a water-repellent treatment.

According to the present invention, the inner peripheral surface of the groove is subjected to a water-repellent treatment. For example, in the case of a conventional comb-shaped tread made of metal such as aluminum die-cast or stainless steel, which is not water-repellent, rainwater tends to accumulate in the groove due to surface tension. Rainwater easily accumulates over the top surface of the ridge. On the other hand, in the present invention, since the inner peripheral surface of the groove is subjected to a water-repellent treatment, it is difficult for rainwater to accumulate in the groove, and the rainwater in the groove is immediately drained along the groove, and the surface of the tread is removed. Can be prevented from being covered by rainwater. This prevents the feet from slipping even during rain.

FIG. 1 is a partially cutaway perspective view showing an escalator tread plate 1 on which the present invention is based, and FIG. 2 shows a schematic structure of an escalator 2 provided with the escalator tread plate 1. FIG. Escalator 2
Is fixed on the existing stairs 3 provided from the lower floor 4 to the upper floor 5 and fixed by a concrete bolt or the like via the mounting member 6. Such an escalator 2 is installed, for example, at a station.

The escalator 2 has a plurality of treads 1 connected to an endless chain 9 stretched over a sprocket wheel 7 provided on the lower floor 4 and a sprocket wheel 8 provided on the upper floor 5. The sprocket wheel 7 is rotationally driven by the motor 15 so that the tread 1 is moved in the traveling direction A in the upper stretch region S1.
As shown by, the circulating drive is performed from the lower floor 4 to the upper floor 5, and used as an ascending escalator. In addition, a handrail 13 circulatingly driven in synchronization with the tread plate 1 is provided at an upper portion.

One end of each tread 1 on the upper floor 5 is connected to the chain 9 so as to be angularly displaceable, and the other end of the lower floor 4 is connected to a riser 10 so as to be angularly displaceable. A roller 11 is provided at the lower end of the riser 10. As the rollers 11 are guided along the guide rails 14, the step board 10 closes the space between the step board 10 and the adjacent step board 10 at the angular displacement position protruding downward in the upper stretch region S1, and the step board 1 is horizontally moved. Drive in a good condition. Upper floor 5
Is reached, the riser 10 is guided by the guide rails 14 and retracts to an angular displacement position that is substantially horizontal with the tread 1 to be folded.

In the reversal area S3 where the step board 1 is inverted from the upper stretch area S1 to the lower stretch area S2, the step board 1 shifts to the lower stretch area S2 with the mounting surface facing the upper side of the step board 1 facing upward. . The rotation guide means 1 is located near the sprocket wheel 7.
2 is provided, and a riser 10 is provided at the upper end portion of the upper stretching region S1.
Is folded, the rotation guide means 12 rotates while supporting the rollers 11 of the riser plate 10 in the folded state, and the upper stretch region in the reversal area S3 in the folded state of the riser plate 10. S
From No. 1 is guided to the lower stay area S2.

In the lower stretch area S2, the riser 10 travels from the upper floor 5 to the lower floor 4 with the riser plate 10 folded. When reaching the lower floor 4, the roller 11 provided on the riser 10 is guided by the guide rail 18,
The riser 10 moves from the lower stretch region S2 to the upper stretch region S1 in the inverted region S4 in a folded state. After reaching the upper stretching area S1, the roller 11 provided on the riser 10
Is guided by the guide rail 18, and the riser 10 is angularly displaced downward by its own weight. When the riser 10 is angularly displaced downward in this manner, a gap between the tread and the tread adjacent to the lower floor 4 is closed by the riser 10. It is possible to prevent the toes from being pinched.

As described above, the tread plate 10 is angularly displaced downward and protrudes in the upper stretch region S1, thereby closing the gap between the tread plates 1, and in the lower stretch region S2, the tread plate 10 is angularly displaced upward and retracts to be folded. Since the escalator 2 is folded, the thickness of the escalator 2 can be reduced, and the thickness W can be, for example, 40 cm or less.

Such an escalator 2 is not limited to being used as an ascending escalator, but can also be used as a descending escalator by reversing the rotation direction of the motor. In this case, the rotation guide means 12 is provided on the lower floor 4 side, and guides the tread plate 10 from the upper stretch area S1 to the lower stretch area S2 in the inverted area S4 in a folded state.

As shown in FIG. 1, the tread 1 comprises a comb plate 20 and a tread board 21. Comb plate 20
Has a plurality of ridges 22 extending along the traveling direction A and arranged at intervals in the width direction perpendicular to the traveling direction A. The tread board 21 is bent in an L-shape as shown, and the comb-tooth plate 20 is fixed to one surface facing upward.

The riser plate 10 is a comb tooth plate 25a, 25
b and the riser board 24. Comb plate 25a,
Reference numeral 25b extends in the up-down direction and has a plurality of ridges 26 arranged at intervals in the width direction perpendicular to the up-down direction.
The riser board 24 is curved, and a comb-tooth plate 25a is fixed to one surface facing outward. Further, a comb tooth plate 25b is fixed to a falling portion 29 which falls below the tread board 21.

Each of the comb-tooth plates 20 and 25 is made of a hard rubber or a synthetic resin.
Numerals 1 and 24 are made of aluminum die-cast or stainless steel, and the comb-tooth plates 20 and 25 are fixed with an adhesive or screws to prevent peeling from the substrates 21 and 24. Each of the comb-tooth plates 20 and 25 has a higher coefficient of friction than a flat metal.

Therefore, even if rainwater or the like accumulates on the tread 1 and covers the upper surface 28 of each ridge 22, the ridge 22 has a large friction coefficient, so that the foot of the occupant slips. Is prevented.

In FIG. 1, reference numeral 23 indicates the boundary between the riser plates 25a, 25b, where the riser plate 10 separates when the riser plate 10 is folded. Therefore, when the riser plate 10 is angularly displaced downward, the upper riser plate 25a and the lower riser plate 25b come into contact with each other, so that the respective riser plates 25a, 25
b also functions as a cushioning material. As a result, generation of noise and vibration can be prevented.

Also, as shown in FIG.
The leading end portion 22a of each of the ridges 22 on the side is formed so as to protrude toward the upper floor 5 toward the upper surface 28. Therefore, as shown in the plan view of the tread 1 shown in FIG. 2
The two tip portions 22a are fitted between the respective protrusions 26 of the riser plate 10, respectively. In such a state, when the tread 1 and the riser 10 are mutually displaced in the lateral direction perpendicular to the running direction A, as shown in FIG. Each tip 22a and each ridge 26 of the riser plate 10 come into contact with each other.

For example, when each ridge is made of metal, such as a conventional tread and riser, when the ridge collides, loud collision noise and vibration are generated, and the ridge may be missing. In the present embodiment, since the ridges 22, 26 of the tread 1 and the riser 10 are made of rubber or synthetic resin,
It has flexibility and resilience, and prevents generation of noise and vibration at the time of contact. Also, it is possible to prevent the protrusions 22 and 26 from being easily chipped when they come into contact with each other.

Further, since the comb-tooth plate 20 is made of a flexible or resilient rubber or synthetic resin, even if the rider falls down, the impact can be reduced. In addition, when each ridge 22 is worn down and rainwater easily overflows from the concave groove 27, only the comb tooth plate 20 can be replaced.

FIG. 4 is a sectional view showing an escalator tread plate 30 according to an embodiment of the present invention. Note that the tread plate 30
Is used for the escalator 2 shown in FIG.

The tread plate 30 is made of aluminum die-cast or stainless steel, extends in the traveling direction A, has a plurality of ridges 22 spaced apart from each other, and has a surface facing the tread plate substrate 31 facing upward. And a covering layer 32. The covering layer 32 is made of a synthetic resin having water repellency, and is coated on the tread board 31 so as to cover at least the concave grooves 34 between the ridges 33. Since the coating layer 32 having high water repellency, that is, a small surface tension is coated on the concave grooves 34 between the ridges 33, rainwater hardly accumulates in the concave grooves 34, and the rainwater on the treads 30 is It will be drained immediately along. Therefore, even when it is raining, it is possible to prevent rainwater from collecting on the tread plate 30 by covering the upper surface 35 of each ridge 33, thereby preventing the rider's feet from slipping.

The coating layer 32 is made of, for example, a silicone resin having high water repellency. In addition, by coating the covering layer 32 with silicone rubber so as to cover not only the concave groove 34 but also the upper surface 35 of the ridge 33, not only does water drain during rainfall, but also the friction coefficient of the upper surface 35 of the ridge 33 increases. Therefore, the feet of the rider can be made hard to slip.

FIG. 5 is a sectional view showing an escalator tread plate 40 according to another embodiment of the present invention. Note that this tread plate 40 is used for the escalator 2 shown in FIG.

The tread plate 40 extends in the traveling direction A and includes a metal tread substrate 41 having a plurality of spaced ridges 42, and a non-slip member fixed on an upper surface 44 of each ridge 42. 43. The non-slip member 43 is made of rubber or synthetic resin having a higher coefficient of friction than a flat metal,
It is fixed to the upper surface of the tread board 41 with screws or an adhesive. By providing the non-slip member 43 in this manner, even if rainwater accumulates on the tread plate 40, it is possible to prevent the rider's feet from slipping. Further, even if a part of the non-slip member 43 is worn, the non-slip member 4
3 can be replaced, and the durability of the tread 40 is improved.

The surface of the step board 41 of the step board 40 may be subjected to a water-repellent treatment so as to cover at least the concave groove 45 between the ridges 42. This makes it difficult for rainwater to drain from the concave groove 45 and to collect on the tread plate 40, thereby further preventing the rider from slipping.

The non-slip member 43 is not limited to a rectangular plate as shown in FIG. 5, but may be a protruding fitting ridge 5 having a central portion protruding and extending in the longitudinal direction as shown in a tread plate 50 shown in FIG.
1 may be the non-slip member 52. At this time,
A non-slip member 52 is provided on each of the protrusions 42 of the tread board 41.
A fitting groove 53 into which the fitting protrusion 51 is fitted is formed. Since the non-slip member 52 is fitted into and fixed to each of the protrusions 42 of the tread board 41 in this way, it is possible to prevent the non-slip member 52 from easily peeling off from the protrusion 42.

The non-slip member is a tread plate 5 shown in FIG.
5, the cross-sectional shape is U-shaped, and the tread board 41
May be fixed to the ridge 42 so as to cover the ridge 42. At this time, the non-slip members 43 may not be provided on all the protrusions 42 but may be provided alternately every other as shown in FIG. Even with such a configuration, it is possible to reliably prevent the rider's feet from slipping. Further, since the non-slip member 56 is fixed so as to cover the ridge 42, the non-slip member 56 is prevented from easily peeling off.

FIG. 8 is a perspective view showing an escalator tread plate 60 according to still another embodiment of the present invention. Note that this tread plate 60 is used for the escalator 2 shown in FIG.

The tread plate 60 includes a tread plate substrate 61 and a non-slip member 6.
The tread board 61 has a plurality of ridges 63 extending along the traveling direction A and spaced from each other. As shown in FIG. 8, trapezoidal cutouts 64 are formed in the protruding portions 63 at intervals in the longitudinal direction, and each of the cutouts 64 has a slip coefficient having a larger coefficient of friction than a flat metal. The stop member 62 fits. The protrusion 63 of the tread plate 60 is constituted by the protrusion 63 of the tread board 61 and the non-slip member 62.

The tread board 61 is made of aluminum die-cast or stainless steel, and the non-slip member 62 is made of rubber or synthetic resin having flexibility and elasticity.

In the conventional tread 1, the ridges are made of flat metal, and the ridges extend along the running direction. Therefore, when the treads are wet with rainwater when descending from the treads onto the floor. When the force is applied to the tread, the feet may slide along the ridges and fall, but the ridges 65 of the present embodiment may fall.
Are alternately spaced apart in the longitudinal direction with metallic ridges 63
And the non-slip member 62 having flexibility and elasticity are provided, so that when a force is applied to the tread to descend from the tread, the flexible non-slip member 62 is dented and mounted. It can be surely prevented that the foot of the person catches on the notch 64 and the foot slides along the ridge 65.

Such a non-slip member 62 is made of, for example, urethane rubber. In addition, the non-slip member 62 is formed in a trapezoidal shape with an expanded lower surface, and is fixed in a state of being fitted into the notch 64, so that it can be prevented from easily being detached.
In addition, by forming the non-slip member 62 with silicone rubber and coating the surface of the tread board 61 with a water-repellent silicone resin, it is possible to prevent rainwater or the like from accumulating in the concave groove between the ridges 65, thereby further It can be made less slippery.
