An embodiment of a man conveyor and a man conveyor safety device will be described below with reference to FIGS. 1 to 8. FIG. In addition, the following embodiment is illustrated in order to help understanding of the structure of a man conveyor and a man conveyor safety device, etc., and does not limit the structure of a man conveyor and a man conveyor safety device.

As shown in FIG. 1, the man conveyor 1 includes, for example, a structure 2 installed on a frame, a transport section 3 for transporting people, and a pair ( 1, only one is shown), a driving unit 5 for driving the transport unit 3 and the balustrade unit 4, and a processing device 6 for controlling the driving unit 5. .

The first direction D1 is a horizontal direction and is referred to as the width direction D1, and the second direction D2 is a horizontal direction perpendicular to the width direction D1 and is referred to as a front-back direction D2 and is referred to as a third direction. D3 is a vertical direction, referred to as an up-down direction D3, and a fourth direction D4 is a direction in which the transport unit 3 transports a person, and is referred to as a transport direction D4 inclined with respect to the front-rear direction D2. The second to fourth directions D2 to D4 are directions included in the same predetermined virtual plane, and the first direction D1 is a direction perpendicular to the virtual plane.

The man conveyor 1 according to the present embodiment is an escalator having stepped treads for transporting people, but is not limited to such a configuration. For example, the man conveyor 1 may be a moving walkway (moving walkway) having a flat tread surface for transporting people.

For example, as in the present embodiment, the conveying portion 3 includes an annular running portion (for example, a chain) 3a that endlessly rotates when driven by the driving portion 5, and a running portion 3a connected to the running portion 3a. and a plurality of steps 3b having treads on which people ride. For example, a pair of running portions 3a are provided apart in the width direction D1, and a plurality of steps 3b are arranged between the pair of running portions 3a, 3a and are arranged in the width direction D1 with respect to each of the running portions 3a. A configuration in which they are rotatably connected around a shaft may also be used.

The balustrade portion 4 includes, for example, as in the present embodiment, a circular handrail belt 4a that rotates endlessly, a balustrade main body portion 4b that supports the handrail belt 4a, and a cover portion 4c that covers the lower end portion of the balustrade main body portion 4b. may be provided.

For example, as in the present embodiment, the driving portion 5 is a pair of driving sources (for example, an electric motor) 5a and a running portion 3a wound so that the step 3b is reversed, and which rotates about the width direction D1 as an axis. Rotating parts (for example, sprockets) 5b, 5b may be provided. The running of the handrail belt 4a may be synchronized with the running of step 3b by transmitting the drive from the drive source 5a to the running portion 3a and the handrail belt 4a.

As shown in FIG. 2, the man conveyor 1 may, for example, form a triangular space by crossing a skeleton or another man conveyor (in FIG. 2, the skeleton) in the width direction D1 view. . On the other hand, the man conveyor 1 may be provided with a protection device 7 and a man conveyor safety device (hereinafter also simply referred to as a "safety device") 10 in the triangular space when viewed in the width direction D1.

For example, the protective device 7 and the safety device 10 may be arranged outside the handrail belt 4a in the width direction D1 as in the present embodiment. The protective device 7 may, for example, be immovably fixed to the upper structural part X1 arranged above. The upper structural part X1 may be, for example, a skeleton (for example, a ceiling, etc.) as in the present embodiment, or may be, for example, another man conveyor arranged above.

As shown in FIG. 3, the safety device 10 includes, for example, a main body 11 arranged outside the handrail belt 4a in the width direction D1, and an upper body 11 arranged above the main body 11 in order to suspend the main body 11. A first connecting body 12 connecting the structural part X1 and the main body 11, a second connecting body 13 connecting the lower structural part 4d arranged below the main body 11 and the main body 11, and the second connecting body 13 It may be provided with an auxiliary connector 14 to be connected.

The lower structural portion 4d may be, for example, a hook member fixed to the cover portion 4c as in the present embodiment. The lower structural part 4d may be, for example, a frame (for example, fittings or the like arranged in a gap between passenger conveyors), or may be, for example, another passenger conveyor arranged below.

For example, as in the present embodiment, the main body 11 includes a plate portion 11a arranged along the transport direction D4 (the front-rear direction D2) and the vertical direction D3, and an end portion in the transport direction D4 (the front-rear direction D2). , and a cylindrical portion 11b extending in the vertical direction D3. Although not particularly limited, the main body 11 may be made of, for example, a transparent hard resin (for example, acrylic resin).

For example, the lower portion of the main body 11 may overlap the balustrade portion 4 as viewed in the width direction D1, as in the present embodiment. Thereby, the upper end of the main body 11 is arranged above the handrail belt 4a, and the lower end of the main body 11 is arranged below the handrail belt 4a.

The diameter of the cylindrical portion 11b may be, for example, larger than the thickness of the plate portion 11a (the dimension in the width direction D1). As a result, since the radius of curvature of the outer peripheral surface of the columnar portion 11b is large, when a person being transported hits the columnar portion 11b of the main body 11, for example, the impact on the person can be reduced.

For example, the first connecting body 12 may be rotatably connected to the upper structural portion X1 and the upper end portion of the main body 11 as in the present embodiment. The number of first connectors 12 is not particularly limited, but a plurality of first connectors 12 (two in this embodiment) may be provided, for example, as in this embodiment. Thereby, it is possible to suppress the main body 11 from swinging around the vertical direction D3.

Although the configuration of the first connection body 12 is not particularly limited, it may be, for example, an elongated body that can be deformed by an external force. In this specification, the term "long body that can be deformed by an external force" may be, for example, a chain as in the present embodiment, or may be a rope (eg, metal rope, resin rope, etc.) or an elastic body. It also includes bodies (eg, springs, etc.) and the like.

For example, the second connection body 13 may be connected to the lower structural portion 4d and the lower end portion of the main body 11 as in the present embodiment. The number of second connectors 13 is not particularly limited, but a plurality of second connectors 13 (two in this embodiment) may be provided, for example, as in this embodiment. Thereby, it is possible to suppress the main body 11 from swinging around the vertical direction D3. The configuration of the second connection body 13 is not particularly limited, but the second connection body 13 may be, for example, an elongated body deformable by an external force.

As shown in FIGS. 4 and 5, the second connecting body 13 may be provided with separating means 13a that can be separated by applying force to the main body 11, for example. As a result, the second connecting body 13 has an upper connecting portion 13b that is connected to the main body 11 when the separating means 13a is separated, and a lower connecting portion 13c that is connected to the lower structural portion 4d when the separating means 13a is separated. and

Therefore, the separating means 13a includes an upper separating portion 13d that is the lower end of the upper connecting portion 13b, and a lower separating portion 13e that is detachable from the upper separating portion 13d and is the upper end of the lower connecting portion 13c. That is, when the separating means 13a is separated, the upper separating portion 13d constitutes at least a part (in this embodiment, the whole) of the upper connecting portion 13b, is connected to the main body 11, and is connected to the lower separating portion 13e. constitutes at least a portion (a portion in this embodiment) of the lower connecting portion 13c and is connected to the lower structural portion 4d.

The auxiliary connector 14 may, for example, connect the upper connection portion 13b and the lower connection portion 13c as in the present embodiment. The configuration of the auxiliary connection body 14 is not particularly limited, but the auxiliary connection body 14 may be, for example, an elongated body that can be deformed by an external force.

Although not particularly limited, for example, the length of the auxiliary connector 14 may be set such that the lower separation portion 13e separates from the lower structural portion 4d when the separation means 13a separates. This can prevent the lower separating portion 13e from falling and colliding with the cover portion 4c and the lower structure portion 4d when the separating means 13a is separated.

As shown in FIG. 6, for example, the upper separating portion 13d may have an annular portion 13f, and the lower separating portion 13e may be inserted into the annular portion 13f. As a result, the upper separation portion 13d and the lower separation portion 13e are connected by stopping the lower separation portion 13e on the inner peripheral portion of the annular portion 13f.

For example, as in the present embodiment, the annular portion 13f is fixed to the fixing portion 13g fixed to the lower end portion of the main body 11 and fixed so as to be rotatable about the width direction D1 with respect to the fixing portion 13g. A movable portion 13h connected to the portion 13g and a holding portion 13i holding the movable portion 13h may be provided. Thereby, the separating means 13a is arranged at the upper end of the second connecting body 13, and the upper separating portion 13d is fixed to the main body 11 by the fixing portion 13g.

The holding portion 13i may be, for example, an elastic body that applies an elastic restoring force to the movable portion 13h as in the present embodiment. Although not particularly limited, the holding portion 13i may be, for example, a torsion spring. Then, for example, as in the present embodiment, the holding portion 13i applies an elastic restoring force to the movable portion 13h, and the engaging portion 13j of the fixed portion 13g and the engaging portion 13k of the movable portion 13h come into contact with each other. 13h may be held in a closed position (position shown in FIG. 6) that closes the interior of annular portion 13f. Note that the enlarged view of the dashed-dotted line area in FIG. 6 shows a longitudinal section of the area.

Then, for example, the inside of the annular portion 13f may be completely closed by positioning the movable portion 13h at the closed position as in the present embodiment. For example, even though the annular portion 13f is partially opened by positioning the movable portion 13h at the closed position, the inside of the annular portion 13f is closed so that the lower separation portion 13e cannot pass through. good.

Next, the operation of the safety device 10 according to this embodiment will be described with reference to FIGS. 6 to 8. FIG.

As shown in FIG. 6, for example, when a wind or a person hits the main body 11 in the width direction D1 and a force is applied to the main body 11 in the width direction D1, the lower separation portion 13e is separated from the annular portion 13f (fixed portion 13g, A force in the width direction D1 is applied to the movable portion 13h). However, the movable portion 13h does not rotate against the force in the width direction D1. Accordingly, since the inside of the annular portion 13f remains closed, it is possible to suppress separation of the lower separating portion 13e from the upper separating portion 13d.

Thus, in the width direction D1, the force that prevents separation between the upper separation portion 13d and the lower separation portion 13e is increased. Thereby, for example, when the wind or a person hits the main body 11 from the width direction D1, it is possible to suppress the main body 11 from swinging in the width direction D1. Therefore, for example, it is possible to prevent the main body 11 swinging in the width direction D1 from hitting the person being conveyed in the step 3b.

On the other hand, as shown in FIG. 7, for example, when the force in the conveying direction D4 is applied to the main body 11 and the lower separating portion 13e applies the force in the conveying direction D4 to the movable portion 13h, the movable portion 13h , rotates around the width direction D1 against the force of the holding portion 13i. As a result, the holding of the movable portion 13h by the holding portion 13i is released, so that the movable portion 13h moves to the open position (position shown in FIG. 7) in which the inside of the annular portion 13f is opened. Therefore, since the inside of the annular portion 13f is opened, the lower separating portion 13e is separated from the upper separating portion 13d.

Thus, in the transport direction D4, the force that prevents separation between the upper separating portion 13d and the lower separating portion 13e is small. As a result, when the person being transported in step 3b collides with the main body 11, the separation means 13a is separated by applying a force in the transport direction D4 to the separation means 13a. Therefore, the connection between the main body 11 and the lower structural portion 4d by the second connector 13 can be released as needed.

By the way, the forces that prevent the separation between the upper separation portion 13d and the lower separation portion 13e have a difference in the directions D1 and D4. Specifically, the force that prevents separation between the upper separation portion 13d and the lower separation portion 13e in the transport direction D4 is greater than the force that prevents separation between the upper separation portion 13d and the lower separation portion 13e in the width direction D1. It's getting smaller. On the other hand, since the upper separating portion 13d is fixed to the main body 11, the directionality of the force that prevents separation between the upper separating portion 13d and the lower separating portion 13e is maintained with respect to the main body 11. FIG.

Note that even when the separation means 13a is separated, the lower connection portion 13c is connected to the upper connection portion 13b by the auxiliary connector 14. As shown in FIG. Thereby, it is possible to suppress separation of the lower connection portion 13c from the upper connection portion 13b. Therefore, for example, as shown in FIG. 8, by lifting the lower connection portion 13c using the auxiliary connector 14, the upper separation portion 13d of the upper connection portion 13b and the lower separation portion 13e of the lower connection portion 13c are separated. Can be easily connected.

As described above, the man conveyor 1 according to the present embodiment includes the man conveyor safety device 10 described above.

According to such a configuration, the separating means 13a of the second connecting body 13 is separated by applying force to the main body 11. As shown in FIG. Thereby, the connection between the main body 11 and the lower structural portion 4d by the second connecting member 13 can be released as needed.

In the passenger conveyor safety device 10 according to the present embodiment, the second connection body 13 includes an upper connection portion 13b connected to the main body 11 when the separation means 13a is separated, and the separation means 13a and a lower connection portion 13c that is connected to the lower structural portion 4d when separated, and the man conveyor safety device 10 is connected to the main body 11 or the upper connection portion 13b (in this embodiment, the upper connection portion 13b ) and the lower connection portion 13c.

According to such a configuration, the lower connection portion 13c is connected to the main body 11 or the upper connection portion 13b by the auxiliary connection body 14 even when the separation means 13a is separated. This can prevent the lower connection portion 13c from separating from the main body 11 or the upper connection portion 13b.

In the passenger conveyor safety device 10 according to this embodiment, the separating means 13a is connected to the upper separating portion 13d connected to the main body 11 when separated, and connected to the lower structural portion 4d when separated. and a force that prevents separation between the upper separating portion 13d and the lower separating portion 13e in the conveying direction D4 in which a person is conveyed is the upper separating portion 13d and the lower separating portion 13e in the width direction D1. A configuration in which the force is smaller than the force that prevents separation between the lower separation portions 13e is preferable.

According to such a configuration, in the transport direction D4 in which a person is transported, the force that prevents separation between the upper separating portion 13d and the lower separating portion 13e is small. As a result, when the person being transported in step 3b collides with the main body 11, the separation means 13a is separated by applying a force in the transport direction D4 to the separation means 13a. On the other hand, in the width direction D1, the force that prevents separation between the upper separation portion 13d and the lower separation portion 13e is large. Thereby, it is possible to suppress the main body 11 from swinging in the width direction D1.

In the passenger conveyor safety device 10 according to this embodiment, the separation means 13a is arranged at the upper end of the second connection body 13, and the upper separation portion 13d is fixed to the main body 11. is preferred.

According to such a configuration, there is a difference in the forces that prevent separation between the upper separation portion 13d and the lower separation portion 13e in the directions D1 and D4. 13 , and the upper separating portion 13 d is fixed to the main body 11 . Thereby, the directionality of the force that prevents the separation between the upper separating portion 13d and the lower separating portion 13e can be maintained with respect to the main body 11. FIG.

In the passenger conveyor safety device 10 according to the present embodiment, the upper separation portion 13d includes an annular portion 13f formed in an annular shape, and the lower separation portion 13e is stopped by the annular portion 13f. The annular portion 13f is inserted through the inside of the annular portion 13f, and the annular portion 13f is movable between a fixed portion 13g fixed to the main body 11 and a closed position that closes the inside and an open position that opens the inside. a movable portion 13h connected to the fixed portion 13g so as to be rotatable about the width direction D1; A configuration including a holding portion 13i for releasing the holding is preferable.

According to such a configuration, since the lower separation portion 13e is inserted into the annular portion 13f of the upper separation portion 13d, the lower separation portion 13e is stopped by the annular portion 13f. Then, when the force in the conveying direction D4 is applied to the main body 11 and the lower separating portion 13e applies the force in the conveying direction D4 to the movable portion 13h, the holding by the holding portion 13i is released, and the movable portion 13h is It rotates about the axial direction D1 and is positioned at the open position. As a result, the inside of the annular portion 13f is opened, so that the lower separating portion 13e is separated from the upper separating portion 13d.

On the other hand, when the force in the width direction D1 is applied to the main body 11 and the lower separation portion 13e applies the force in the width direction D1 to the movable portion 13h, the movable portion 13h rotates about the width direction D1. Since it is movably connected to the fixed portion 13g, the movable portion 13h is positioned at the closed position without rotating. Accordingly, since the inside of the annular portion 13f remains closed, it is possible to suppress separation of the lower separating portion 13e from the upper separating portion 13d.

In addition, the man conveyor 1 and the man conveyor safety device 10 are not limited to the configurations of the above-described embodiments, and are not limited to the above-described effects.
