Detailed Description

Hereinafter, a step and a passenger conveyor according to an embodiment of the present invention will be described with reference to fig. 1 to 7. In the drawings, the same reference numerals are given to the common members.

Structure of passenger conveyor

First, the structure of the passenger conveyor will be described with reference to fig. 1.

Fig. 1 is a schematic configuration diagram of a passenger conveyor according to an embodiment of the present invention.

As shown in fig. 1, the passenger conveyor 1 is an inclined passenger conveyor, a so-called escalator, which is installed between an upper floor and a lower floor of a building structure. The passenger conveyor 1 includes a frame 2 provided to span upper and lower floors of a building structure, an endless step chain 3, an upper terminal sprocket 4, a lower terminal sprocket 5, a plurality of steps 6 on which passengers ride, and a balustrade panel 7.

The frame body 2 is formed of a truss structure having a lower frame, an upper frame opposed to the lower frame, and a vertical frame connecting the lower frame and the upper frame. An upper machine chamber 11 and a lower machine chamber 12 are provided at both ends of the frame 2 in the longitudinal direction, respectively. The upper machine room 11 is closed by an upper access floor 13, and the lower machine room 12 is closed by a lower access floor 14.

The upper terminal sprocket 4 is disposed in the upper machine room 11, and the lower terminal sprocket 5 is disposed in the lower machine room 12. Further, a step drive unit (not shown) is disposed in the upper machine room 11 or the lower machine room 12. The upper terminal sprocket 4 or the lower terminal sprocket 5 is driven to rotate by a step drive portion (not shown).

Further, the step chain 3 is wound around the upper terminal sprocket 4 and the lower terminal sprocket 5. For example, when the step driving portion (not shown) is driven to rotate the upper terminal sprocket 4, the step chain 3 moves circularly and the lower terminal sprocket 5 rotates.

The plurality of steps 6 are connected to the step chain 3 and circulate together with the step chain 3. The plurality of steps 6 are guided by rails 15 (see fig. 2) provided in the housing 2 and pass through the outward path side exposed from the housing 2. The plurality of steps 6 are guided by rails (not shown) provided in the housing 2 and pass through the inside of the housing 2, that is, the circuit side.

The balustrade panels 7 are erected and supported on the upper portion of the housing 2, and are disposed on both sides of the housing 2 in the width direction. Therefore, the balustrade panels 7 are disposed on both sides of the plurality of steps 6 on the passage side. A moving handrail 16 is provided at the periphery of the balustrade panel 7. The moving handrail 16 is formed of an endless belt member and is movably supported by the balustrade panel 7. The moving handrail 16 circularly moves in synchronization with the movement of the plurality of steps 6 in the circular movement.

2. Step structure

Next, the structure of the step 6 will be described with reference to fig. 2 to 4.

Fig. 2 is a perspective view showing the vicinity of the step 6 of the passenger conveyor 1. Fig. 3 is a top view of the step 6. Fig. 4 is a front view of the step 6.

As shown in fig. 2, the step 6 includes a step main body 21, a shaft structure 22 connecting the step main body 21, and a rear end boundary strip 23 attached to the step main body 21. The shaft structure 22 of the step 6 includes a step shaft 22A connected to the step chain 3, a bearing 22B, and a roller 22C. The rollers 22C are rotatably attached to both end portions of the step shaft 22A, and roll on the rails 15 of the frame 2.

[ step body ]

The step body 21 is made of, for example, aluminum die casting, and includes a tread surface portion (cleat) 24 on which a passenger rides, a rising portion (riser) 25 continuous with the tread surface portion 24, and a triangular bracket 26 coupled to the tread surface portion 24, as shown in fig. 2. The tread surface portion 24 is formed in a rectangular plate shape, and has a tread surface 24a on which the passenger rides and a back surface which is a surface opposite to the tread surface 24 a. The tread surface 24a has a plurality of grooves.

The rising portion 25 is formed in a plate shape that continues to one long side of the step surface portion 24 and protrudes substantially perpendicularly, and has a rising surface 25 a. A plurality of grooves are formed in the rising surface 25a in the same manner as the tread surface 24 a.

The triangular bracket 26 is formed in a substantially triangular frame shape, and one side thereof is fixed to the back surface of the step surface portion 24. Further, a roller 28 is rotatably attached to a corner portion of the triangular bracket 26 formed by two sides not fixed to the step surface portion 24. The rollers 28 roll on the rails 15 of the frame 2.

As shown in fig. 3, a front end boundary strip 31 is integrally formed at the front end of the step surface portion 24, and side end boundary strips 32 and 33 are integrally formed at both side ends of the step surface portion 24. The rear end of the tread surface portion 24 is a portion where the tread surface 24a and the rising surface 25a intersect, and forms a corner portion of the step main body 21.

[ Back end edge bar ]

As shown in fig. 4, the rear end boundary strip 23 is attached to the rear end of the step surface portion 24 by a fixing screw 35. The rear end boundary strip 23 is provided as a member different from the step main body 21.

The rear end boundary strip 23 is formed in a rectangular parallelepiped shape extending along the rear end (one long side) of the step surface portion 24. The upper surface 23a of the rear end edge strip 23 and the tread surface 24a form the same plane. Further, a groove having continuity with the plurality of grooves formed in the tread surface 24a is formed in the upper surface 23a of the rear end boundary bar 23.

A rear surface 23d of the rear edge strip 23, which will be described later, is flush with the rising surface 25 a. Further, a groove continuous with the plurality of grooves formed on the rising surface 25a is formed on the rear surface 23d of the rear end boundary strip 23.

[ mounting Structure of rear end edge strip ]

Next, the mounting structure of the rear end boundary strip 23 will be described with reference to fig. 5 to 7.

Fig. 5 is a sectional view taken along line a-a shown in fig. 4. Fig. 6 is a sectional view taken along line B-B shown in fig. 4. Fig. 7 is a sectional view taken along the line C-C shown in fig. 4.

In general, when a passenger runs down, the feet of the passenger tend to ride on the rear end boundary strip of the steps. When the foot is put on the corner of the rear end boundary strip, a rotational moment acts on the rear end boundary strip, and the rear end boundary strip may fall off from the step main body. Therefore, when the rear end border is provided as a member different from the step main body, it is desirable to firmly fix the rear end border to the step main body. Therefore, in the present embodiment, the rear end boundary strip 23 is formed of a material having an appropriate strength and is configured not to fall off from the step main body 21 in the upward direction.

In the rear end boundary bar 23, a direction along the rear end portion of the tread surface portion 24 is defined as a longitudinal direction, and a direction orthogonal to the longitudinal direction and orthogonal to the tread surface 24a is defined as a short direction. As shown in fig. 5, the rear end boundary strip 23 has an upper surface 23a and a lower surface 23b as surfaces facing in a direction orthogonal to the tread surface 24a, and a front surface 23c and a rear surface 23d as surfaces facing in the short side direction.

A plurality of positioning pins 41 are provided on the lower surface 23b of the rear end boundary strip 23. The positioning pin 41 shows a specific example of the positioning protrusion of the present invention. The positioning pins 41 are formed in a cylindrical shape protruding substantially perpendicularly from the lower surface 23b, and are arranged at appropriate intervals in the longitudinal direction of the rear end boundary bar 23. The positioning projection of the present invention is not limited to a pin, and any shape may be applied as long as it protrudes from the lower surface 23 b.

The front surface 23c of the rear end edge strip 23 faces the step surface portion 24. The front surface 23c of the rear end boundary bar 23 is provided with a first engaging portion 42. The first engaging portion 42 shows a specific example of the engaging portion of the present invention. The first engaging portion 42 is a protruding portion formed on the lower surface 23b side of the front surface 23c, and is continuous in the longitudinal direction. The first engaging portion 42 has an inclined abutment surface 42a facing obliquely upward.

Further, a second engaging portion 43 is provided on the rear surface 23d of the rear end boundary bar 23. The second engaging portion 43 shows a specific example of the engaging portion for standing of the present invention. The second engaging portion 43 is formed by cutting out a corner portion where the rear surface 23d and the lower surface 23b intersect, and is continuous in the longitudinal direction. The second engaging portion 43 has an inclined abutment surface 43a facing obliquely downward.

On the other hand, the tread surface portion 24 of the step main body 21 is provided with a plurality of fitting holes 51 into which the plurality of positioning pins 41 of the rear end boundary strip 23 are fitted. By fitting the plurality of positioning pins 41 of the rear end boundary strip 23 into the plurality of fitting holes 51, the rear end boundary strip 23 can be easily positioned in the step main body 21.

Further, by fitting the plurality of positioning pins 41 of the rear end boundary strip 23 into the plurality of fitting holes 51, rotation of the rear end boundary strip 23 can be suppressed when a rotational moment acts on the rear end boundary strip 23.

The pedal surface portion 24 is provided with a first engaged portion 52 that engages with the first engaging portion 42 of the rear end boundary strip 23. The first engaged portion 52 shows a specific example of the engaged portion of the present invention. The first engaged portion 52 is formed as a concave portion corresponding to the first engaging portion 42. The first engaged portion 52 has an inclined abutment surface 52a facing obliquely downward.

When the first engaging portion 42 is engaged with the first engaged portion 52, the first engaging portion 42 overlaps the first engaged portion 52 in a direction intersecting the tread surface 24a and is located below the first engaged portion 52. The inclined contact surface 42a of the first engaging portion 42 contacts the inclined contact surface 52a of the first engaged portion 52. Thus, even if a rotational moment acts on the rear end boundary strip 23, the first engaged portion 52 locks the rotation of the rear end boundary strip 23, and therefore, the rear end boundary strip 23 can be prevented from falling off from the step main body 21.

The rising portion 25 of the step main body 21 is provided with a second engaged portion 53 that engages with the second engaging portion 43 of the rear end boundary strip 23. The second engaged portion 53 shows a specific example of the engaged portion on the rising side of the present invention. The second engaged portion 53 is formed as a convex portion corresponding to the second engaging portion 43. The second engaged portion 53 has an inclined contact surface 53a facing obliquely upward.

When the second engaging portion 43 is engaged with the second engaged portion 53, the second engaging portion 43 overlaps the second engaged portion 53 in the direction intersecting the rising surface 25a, and is located closer to the first engaging portion 42 than the second engaged portion 53. The inclined contact surface 43a of the second engaging portion 43 contacts the inclined contact surface 53a of the second engaged portion 53. Thus, when a force acting in the direction of the short side and away from the step surface portion 24 is applied to the rear end boundary strip 23, the second engaged portion 53 locks the movement of the rear end boundary strip 23. As a result, the rear end boundary strip 23 can be prevented from falling off from the step main body 21.

As shown in fig. 6, a through hole 45 is provided in the bottom surface of the predetermined groove of the rear end boundary bar 23. The rear end boundary strip 23 of the present embodiment has a plurality of predetermined grooves in which the through holes 45 are formed. The screw shaft portion 35a of the fixing screw 35 penetrates the through hole 45. The through hole 45 is subjected to spot facing 45a for receiving the screw head 35b of the fixing screw 35. Therefore, the screw head 35b of the fixing screw 35 does not protrude from the bottom surface of the groove of the rear end boundary strip 23.

On the other hand, the tread surface portion 24 of the step main body 21 is provided with a nut fitting hole 55 facing the through hole 45 of the rear end boundary 23. A snap nut 36 is fitted into the nut fitting hole 55. The rear end boundary strip 23 is fixed to the step surface portion 24 (the step main body 21) by screwing the screw shaft portion 35a of the fixing screw 35, which penetrates the through hole 45 of the rear end boundary strip 23, to the snap nut 36.

As shown in fig. 7, the through-holes 45 are not provided in the grooves other than the predetermined grooves of the rear end boundary bar 23. That is, the through holes 45 are provided at appropriate intervals in the longitudinal direction of the rear end boundary bar 23. The positioning pins 41 (see fig. 5) are also provided at appropriate intervals in the longitudinal direction of the rear end boundary bar 23.

The positioning pins 41 are not provided at positions facing the grooves of the lower surface 23b of the rear end boundary strip 23. Therefore, the position where the positioning pin 41 is provided and the position where the through hole 45 is provided do not overlap, and the rear end boundary strip can be easily designed. The positioning pins 41 may be provided at positions facing grooves other than the predetermined grooves on the lower surface 23b of the rear end boundary bar 23. That is, the positioning pin of the present invention may be provided at any position as long as it does not overlap with the fixing screw or the snap nut.

3. Summary of the invention

As described above, the step 6 of the above embodiment includes the step main body 21 and the rear end boundary strip 23. The step main body 21 has a tread surface portion 24 provided with a tread surface 24a on which a passenger rides. And a rising portion 25 having a rising surface 25a continuous with the tread surface 24 a. The rear end boundary strip 23 is attached to a corner portion where the tread surface 24a and the rising surface 25a of the step main body 21 intersect, and has a first engaging portion 42 that engages with the tread surface portion 24. The pedal surface portion 24 has a first engaged portion 52 that engages with the first engaging portion 42 of the rear end boundary 23. Further, in the direction in which the first engaging portion 42 intersects the tread surface 24a, the first engaging portion 42 overlaps the first engaged portion 52 and is positioned below the first engaged portion 52.

According to such a configuration, since the first engaging portion 42 of the rear end boundary strip 23 is engaged with the first engaged portion 52 of the step main body 21, even if a rotational moment acts on the rear end boundary strip 23, the first engaged portion 52 locks the rotation of the rear end boundary strip 23. As a result, the rear end boundary strip 23 can be prevented from falling off from the step main body 21.

In the above embodiment, the first engaging portion 42 has the inclined contact surface 42a, and the first engaged portion 52 has the inclined contact surface 52a that contacts the inclined contact surface 42 a. Thus, the first engaging portion 42 is in surface contact with the first engaged portion 52, and the rotational moment acting on the rear end edge strip 23 can be prevented from concentrating on the first engaging portion 42 or a part of the first engaged portion 52. As a result, the first engaging portion 42 and the first engaged portion 52 can be prevented from being damaged.

The rear end boundary strip 23 of the above embodiment has the positioning pins 41, and the step main body 21 has the fitting holes 51 into which the positioning pins 41 are fitted. This makes it possible to easily position the rear end boundary strip 23 on the step main body 21. In addition, when the rotational moment acts on the rear end boundary strip 23, the rotation of the rear end boundary strip 23 can be suppressed.

The rear edge border 23 of the above-described embodiment has the second engaging portion 43 that engages with the rising portion 25, and the rising portion 25 has the second engaged portion 53 that engages with the second engaging portion 43 of the rear edge border 23. The second engaging portion 43 overlaps the second engaged portion 53 in a direction intersecting the rising surface 25a, and is located closer to the first engaging portion 42 than the second engaged portion 53. Thus, even if a force is applied to the rear end boundary strip 23 in a direction intersecting the rising surface 25a and in a direction away from the step surface portion 24, the movement of the rear end boundary strip 23 can be locked by the second engaged portion 53. As a result, the rear end boundary strip 23 can be prevented from falling off from the step main body 21.

The embodiments of the steps and the passenger conveyor according to the present invention have been described above, including the operational effects thereof. However, the steps and the passenger conveyor of the present invention are not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention described in the claims.

For example, in the above-described embodiment, the rear end boundary strip 23 is fixed to the step main body 21 using the fixing screw 35 and the snap nut 36. However, the fixing of the boundary strip to the step main body according to the present invention is not limited to the fixing screw and the snap nut, and for example, a nut and a fixing screw may be used, or a fixing screw may be screwed into the step main body.

In the above embodiment, the inclined abutment surface 42a provided on the rear end boundary strip 23 is configured to abut against the inclined abutment surface 52a of the step main body 21. However, the engaging portion of the present invention is not limited to the case where it has an inclined surface that abuts against the engaged portion, and the engaging portion may be disposed below the engaged portion in a direction intersecting with the tread surface. Therefore, the engaging portion of the present invention may have a surface parallel to the tread surface, and the surface may abut against the engaged portion.

In the above embodiment, the inclined abutment surface 43a provided on the rear end boundary strip 23 is configured to abut against the inclined abutment surface 53a of the step main body 21. However, the rising engaging portion (second engaging portion) according to the present invention is not limited to the case where it has an inclined surface that abuts against the rising-side engaged portion (second engaged portion), and the rising engaging portion may be located on the engaging portion side of the rising-side engaged portion in the direction intersecting the rising surface. Therefore, the engaging portion for standing of the present invention may have a surface parallel to the standing surface, and the surface may abut against the engaged portion on the standing side.

In the present specification, terms such as "parallel" and "orthogonal" are used, but they mean not only "parallel" and "orthogonal" strictly, but also "substantially parallel" and "substantially orthogonal" within a range in which they can function, including "parallel" and "orthogonal".
