Description

  The present invention relates to a man conveyor system in which a fixed passage such as a staircase or a sidewalk is attached to a man conveyor such as an escalator for transporting people and a moving sidewalk.

  For example, in a commercial facility such as a department store or a store, or a facility that is used by an unspecified number of people such as a transportation terminal, a stairs is often provided next to an escalator as a man conveyor.

  As disclosed in, for example, Patent Document 1, a conventional escalator includes a gantry serving as a foundation structure, a movable step train that travels endlessly along the gantry, and a balustrade supported by the gantry. .

  The gantry has a left truss and a right truss, and is bridged obliquely between the lower floor and the upper floor of the building. The movable step sequence has a plurality of steps on which a person rides, and these steps are connected endlessly via a step chain. The movable step train is configured to endlessly travel in the upward or downward direction between the left truss and the right truss of the gantry by power transmission from a drive device installed on the gantry.

  Further, the balustrade rises from the upper end of the left truss and the upper end of the right truss and extends over the entire length of the gantry. A handrail belt is attached to the outer periphery of the balustrade. The handrail belt runs endlessly in synchronization with the movable step sequence so that a person who has entered the movable step sequence can be gripped.

  On the other hand, the stairs have a plurality of treads. The treads are arranged with a predetermined step from the lower floor to the upper floor of the building. The conventional staircase is supported by a plurality of columns that stand up from the floor on the lower floor, and connects the lower floor and the upper floor at substantially the same height as the movable step row of the escalator.

Therefore, the stairs located beside the escalator are in a state of being separated from the escalator by a load, and most of the load of the person going up and down the stairs is received by the tread and the support.
JP 2002-68650 A

  In the escalator, a pedestal serving as a foundation structure is bridged between a lower floor and an upper floor of the building. Therefore, the space under the escalator is a space where people can freely come and go.

  On the other hand, the stairs located beside the escalator are supported by a plurality of support columns protruding from the lower floor. In other words, since a plurality of pillars are located between the lower floor and the stairs, the presence of these pillars inevitably loses the feeling of opening under the stairs.

  As a result, the space under the stairs cannot be used effectively, and there is still room for improvement one step from the design aspect around the stairs.

The object of the present invention is to effectively utilize the space under the man conveyor and the fixed passage, to obtain the appearance that the fixed passage is floating in the air, and to support the fixed passage in a cantilever state. The object is to obtain a man conveyor system that can prevent twisting .

In order to achieve the above object, a man conveyor system according to one embodiment of the present invention includes a man conveyor and a fixed passage. The man conveyor is configured by (1) a gantry having a left truss and a right truss, and (2) a plurality of movable steps connected endlessly via an endless traveling body. A movable step sequence that travels endlessly between the left truss and the right truss.
The fixed passage has a plurality of fixed steps supported in a cantilevered state on the frame of the man conveyor, and horizontally protrudes toward the sides of the frame . It is arranged along the running direction . The fixing step includes a tread board, and a tread board support member that is fixed to the tread board and protrudes toward the gantry from the tread board and straddles between the left truss and the right truss. The tread board support member includes a fixed end located on the opposite side of the tread board, and an intermediate portion located between the fixed end and the tread board. While being fixed to one truss of the left truss and the right truss, the intermediate portion of the tread support is movably supported by the other truss of the left truss and the right truss It is characterized by that.

ADVANTAGE OF THE INVENTION According to this invention, while being able to utilize effectively under a man conveyor and a fixed channel | path, the mysterious external appearance that the fixed channel | path floats in the air can be obtained, and it is convenient also in terms of design. Moreover, even though the fixed path is supported in a cantilevered manner relative to the pedestal of the man conveyor, the load transmitted from the fixed path to the pedestal can be distributed to both the left and right trusses, and the gantry can be twisted. Can be prevented.

  Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

  The man conveyor system includes an escalator 1 which is an example of a man conveyor and a fixed staircase 2 as a fixed passage. As schematically shown in FIG. 1, the escalator 1 includes a gantry 3 as a foundation structure. The gantry 3 includes a lower floor horizontal portion 4 installed on the lower floor 1F, an upper floor horizontal portion 5 installed on the upper floor 2F, a lower floor horizontal portion 4 and an upper floor horizontal portion 5 It is comprised with the inclination part 6 which connects between.

  A first support fitting 7 is fixed to the end of the lower floor side horizontal portion 4. The first support fitting 7 extends in the width direction of the gantry 3 and is supported by the lower floor 1F. A second support fitting 8 is fixed to the end of the upper floor side horizontal portion 5. The second support fitting 8 extends in the width direction of the gantry 3 and is supported by the upper floor 2F.

  Further, as shown in FIGS. 1 and 2, the upper floor side horizontal portion 5 and the inclined portion 6 of the gantry 3 are located in a space S between the floor 1F on the lower floor and the floor 2F on the upper floor. The left side surface, the right side surface, and the bottom surface of the gantry 3 are each covered with an exterior panel 9.

  As shown in FIGS. 2 and 4, the gantry 3 has a left truss 10 and a right truss 11. The left truss 10 and the right truss 11 face each other at a predetermined interval in the width direction of the escalator 1.

  The left truss 10 is assembled by welding or bolting the upper main chord member 12, the lower main chord member 13, and the plurality of vertical bars 14 to each other. The upper main chord member 12 and the lower main chord member 13 are arranged at intervals in the height direction of the gantry 3. The vertical beam 14 is bridged between the upper main chord member 12 and the lower main chord member 13.

  Similarly, the right truss 11 is assembled by welding or bolting the upper main chord member 15, the lower main chord member 16, and the plurality of vertical bars 17 to each other. The upper main chord material 15 and the lower main chord material 16 are arranged at intervals in the height direction of the gantry 3. The vertical beam 17 is bridged between the upper main string material 15 and the lower main string material 16.

As the vertical bars 14 and 17 of the left and right trusses 10 and 11, a bar, a panel, or a structure in which a bar and a panel are combined can be used. In particular, in the inclined portion 6 of the gantry 3 straddling between the lower floor and the upper floor, it is desirable to use the vertical rails 14 and 17 in which a bar material and a panel material are combined in order to resist bending load.

  As shown in FIGS. 5 and 6, a step receiving member 18 a is attached to the lower main chord member 13 of the left truss 10. Similarly, a step receiving member 18 b is attached to the lower main chord member 16 of the right truss 11. The step receiving members 18 a and 18 b are provided at locations corresponding to the inclined portion 6 of the gantry 3, and extend straight along the inclined portion 6. The step receiving members 18a and 18b are fixed to the side surfaces of the lower main chord members 13 and 16 by a known means such as welding or bolting, and project below the lower main chord members 13 and 16. For this reason, the step receiving members 18a and 18b are part of the elements constituting the left and right trusses 10 and 11, respectively.

  As shown in FIG. 1, left and right driven sprockets 19 (only one is shown) are supported on the lower floor side horizontal portion 4 of the gantry 3. A driving device 20 having a motor and a speed reducer and left and right driving sprockets 21 (only one of which is shown) are supported on the upper horizontal portion 5 of the gantry 3. A drive chain 22 is wound around the output end of the drive device 20 and one drive sprocket 21. Torque output from the drive device 20 is transmitted to the drive sprocket 21 via the drive chain 22, whereby the drive sprocket 21 rotates.

  A movable step row 23 is accommodated between the left truss 10 and the right truss 11 of the gantry 3. The movable step row 23 includes a plurality of steps 24 on which a person gets in, and left and right step chains 25 (only one is shown) that connects these steps 24 at equal intervals.

  The step 24 is an example of a movable step and includes left and right front wheels 26a and 26b and left and right rear wheels (not shown). The front wheels 26 a and 26 b and the rear wheel are located outside the left and right side surfaces of the step 24. The step chain 25 is an example of an endless traveling body, and is wound endlessly between the driven sprocket 19 and the drive sprocket 21.

  Therefore, the movable step sequence 23 has a forward path 23a for carrying a person and a return path 23b passing under the forward path 23a, and a gap G along the height direction of the gantry 3 is formed between the forward path 23a and the return path 23b. Is formed.

  As shown in FIGS. 4 to 6, guide rails 27a and 27b that contact the front wheels 26a and 26b and guide rails (not shown) that contact the rear wheels are supported inside the left truss 10 and inside the right truss 11, respectively. Has been. The guide rails 27a and 27b extend along the forward path 23a and the return path 23b of the movable step row 23.

  When the drive sprocket 21 receives torque from the drive device 20 and rotates, the step chain 25 travels endlessly. As a result, the step 24 travels along the guide rails 27a and 27b, and the person who gets on the step 24 moves from the lower floor F1 to the upper floor F2 or from the upper floor F2 to the lower floor F1. It is designed to be transported towards.

  Instead of the driven sprocket 19, an inversion rail (not shown) curved in an arc shape may be installed on the lower floor side horizontal portion 4 of the gantry 3. The reversal rail reverses the traveling direction of the step chain 25 by slidably contacting the step chain 25.

  As shown in FIGS. 1 and 2, balustrades 28 are fixed to the upper edge of the left truss 10 and the upper edge of the right truss 11, respectively. The balustrade 28 rises from the left and right trusses 10 and 11 and extends over the entire length of the gantry 3.

A handrail belt 29 is attached to the outer periphery of the balustrade 28. The handrail belt 29 travels endlessly in synchronization with the movable step row 23 so that a person who has entered the forward path 23a of the movable step row 23 can be gripped.

  As shown in FIG. 2, the fixed staircase 2 connects the lower floor 1F and the upper floor F2 on the right side of the escalator 1, for example. The fixed staircase 2 has a plurality of fixed steps 31. The fixing steps 31 are arranged stepwise at an angle corresponding to the inclination of the gantry 3.

  In other words, the plurality of fixed steps 31 are arranged stepwise along the traveling direction of the movable step row 23 of the escalator 1, and a step along the height direction of the gantry 3 is formed between the adjacent fixed steps 31. Has been.

  FIG. 3 discloses an example of the fixing step 31 constituting the fixed staircase 2. Each fixing step 31 includes, for example, a first treadboard support member 32a, a second treadboard support member 32b, a tread plate 33, a frame body 34, and a bottom plate 35.

  The first and second tread board support members 32a and 32b each have a bar shape having a square cross-sectional shape, and are arranged in parallel to each other with a space in the front-rear direction of the fixing step 31. As the first and second tread board support members 32a and 32b, for example, H-shaped steel may be used, and the cross-sectional shape thereof is arbitrary.

  The tread board 33 is fixed so as to straddle over the first and second tread board support members 32a and 32b. The frame body 34 is fixed to the outer peripheral portion of the lower surface of the tread plate 33 and surrounds the first and second tread plate support members 32a and 32b. The bottom plate 35 is fixed to the lower surface of the frame body 34 so as to cover the first tread plate support member 32a, the second tread plate support member 32b, and the tread plate 33 from below. One end of each of the first and second tread board support members 32 a and 32 b penetrates the frame body 34 and protrudes toward the mount 3 from the tread board 33.

  As shown in FIGS. 2 and 4, the fixed staircase 2 is supported by the gantry 3 in a cantilever state in a range from the upper floor side horizontal portion 5 to the inclined portion 6 of the gantry 3. FIG. 4 discloses the relationship between the plurality of fixing steps 31 located on the side of the upper horizontal portion 5 of the gantry 3 and the gantry 3. In a plurality of fixing steps 31 located beside the upper horizontal portion 5, the middle portion of the vertical beam 17 that constitutes the right truss 11 with one end of the first and second tread support members 32 a and 32 b passing through the exterior panel 9. Has been directly hit. The abutting portion between one end of the first and second tread board support members 32a and 32b and the vertical rail 17 is firmly fixed by means such as welding or bolting.

  Therefore, the first and second tread board support members 32a and 32b project horizontally from the vertical beam 17 of the right truss 11 toward the right side of the gantry 3, and horizontally support the tread board 33 on which a person rides. .

  5 and 6 disclose the relationship between the plurality of fixing steps 31 located on the side of the inclined portion 6 of the gantry 3 and the gantry 3. The plurality of fixing steps 31 positioned beside the inclined portion 6 are arranged in a stepped manner on the right side of the step receiving member 18b of the right truss 11.

  In each fixing step 31, for example, when the fixed staircase 2 is viewed from the upper floor direction, the first tread plate support member 32 a is positioned at the front end of the tread plate 33, and the second tread plate support plate 32 b is at the rear end of the tread plate 33. positioned.

  One end of the first tread board support member 32a is fitted into a fitting hole 37 that penetrates the exterior panel 9 and is opened in the step receiving member 18b. A fitting portion between one end of the first tread board support member 32a and the fitting hole 37 of the step receiving member 18b is firmly fixed by means such as welding. Therefore, as shown in FIG. 5, the first tread board support member 32 a protrudes horizontally from the step receiving member 18 b of the right truss 11 toward the right side of the gantry 3.

  As shown in FIG. 6, the second tread support material 32 b has an extension 38 that extends coaxially below the gantry 3. The extension 38 has a length that spans between the step receiving member 18 a of the left truss 10 and the step receiving member 18 b of the right truss 11. Therefore, the second tread plate support member 32 b including the extension portion 38 includes a fixed end 39 a located on the opposite side of the tread plate 33 and an intermediate portion 39 b located between the fixed end 39 a and the tread plate 33. . The fixed end 39a is defined by the tip of the extension 38. The intermediate part 39 b is defined by the starting end of the extension part 38.

  The intermediate portion 39b of the second tread support member 32b penetrates the fitting hole 37 of the step receiving member 18b of the exterior panel 9 and the right truss 11, and is firmly fixed to the step receiving member 18b by means such as welding. Yes. The fixed end 39 a of the second tread board support member 32 b is fitted into a fitting hole 40 opened in the step receiving member 18 a of the left truss 10. The fitting portion between the fixed end 39a and the fitting hole 40 of the step receiving member 18a is firmly fixed by means such as welding.

  Accordingly, the second tread board support member 32b protrudes horizontally from the step receiving members 18a and 18b of the left and right trusses 10 and 11 toward the right side of the gantry 3, and cooperates with the first tread board support member 32a. Thus, the tread 33 is supported horizontally.

  In the present embodiment, although several steps of fixing steps 31 located below the inclined portion 6 of the gantry 3 are not shown, one end of the first and second tread support members 32a and 32b is connected to the right truss 11. Are welded to an intermediate portion of the vertical beam 14 constituting the. Therefore, several fixed steps 31 located below the inclined portion 6 of the gantry 3 are cantilevered to the right truss 11 with the same structure as the several fixed steps 31 located on the upper floor side horizontal portion 5 of the gantry 3. It is supported.

  According to the first embodiment having such a configuration, the fixed staircase 2 attached to the right side of the escalator 1 is directly supported in a cantilever manner on the mount 3 of the escalator 1. In other words, the fixed staircase 2 that connects the lower floor and the upper floor can be supported by using the gantry 3 that is the basic structure of the escalator 1.

  For this reason, it is not necessary to arrange | position the support | pillar which supports the fixed staircase 2 on the floor 1F of a lower floor, and it can utilize effectively as the channel | path etc. for which a person passes under the escalator 1 and the fixed staircase 2, for example. At the same time, since there is no support that supports the fixed staircase 2 from below, it is possible to obtain a mysterious appearance as if the fixed staircase 2 is floating in the space between the lower floor and the upper floor. There is an advantage that it becomes convenient.

  Further, according to the above configuration, the plurality of fixing steps 31 located beside the inclined portion 6 of the gantry 3 are fixed to the right truss 11 of the gantry 3 with the first tread plate support member 32a that supports the front end portion of the tread plate 33, A second tread support member 32 b that supports the rear end of the tread 33 is fixed to both the right truss 11 and the left truss 10. For this reason, when receiving the weight of the fixed staircase 2 and the weight of the person who has entered the fixed staircase 2 with the gantry 3 of the escalator 1, the load transmitted from the fixed stairs 2 side to the gantry 3 is applied to the left truss 10 and the right truss 11. It can be distributed to both.

  Therefore, the load burden of the right truss 11 adjacent to the fixed staircase 2 can be reduced, and the gantry 3 can be prevented from being twisted.

  In the plurality of fixing steps 31 located beside the upper floor side horizontal portion 5 of the gantry 3, the first and second tread plate support members 32 a and 32 b of each fixing step 31 are fixed only to the right truss 11. . Therefore, the load from the fixing step 31 is concentrated on the right truss 11, and the right truss 11 is twisted.

  In this case, in order to counter the load from the fixing step 31, for example, a plurality of reinforcing materials straddling between the upper main chord material 15 and the lower main chord material 16, or the side surface of the upper main chord material 15 and It is desirable to attach a strength member such as a flat bar to the side surface of the lower main chord member 16.

  In addition, for example, by increasing the height dimension (depth dimension) of the upper floor side horizontal part 5, the section modulus of the upper floor side horizontal part 5 is increased, and the upper floor side horizontal part 5 is configured not to be twisted. Good.

  The present invention is not limited to the first embodiment described above, and can be implemented with various modifications without departing from the spirit of the invention.

  For example, according to the first embodiment, at the position corresponding to the inclined portion 6 of the gantry 3, the first tread support material 32 a of the fixing step 31 is cantilevered to the step receiving material 18 b of the right truss 11. It is supported.

  However, the present invention is not limited to this. For example, the left and right step receiving members 18a and 18b are extended below the pedestal 3, and the position of the fixed staircase 2 with respect to the pedestal 3 is slightly lowered. The support members 32a and 32b may be bridged between the left and right step receiving members 18a and 18b.

  According to this configuration, the load transmitted from the fixed step 31 side to the inclined portion 6 of the gantry 3 can be distributed to both the left truss 10 and the right truss 11. Therefore, it is more convenient to prevent the inclined portion 6 of the gantry 3 from being twisted.

  FIG. 7 discloses a second embodiment of the present invention.

In the second embodiment, the vibration isolator 50 is interposed between the tread plate 33 of each fixing step 31 and the first and second tread plate support members 32a and 32b, and between the tread plate 33 and the frame 34. Has been. The vibration isolator 50 is formed of, for example, a plate-like rubber-like elastic body having approximately the same size as the tread board 33, and the tread board 33 is elastic with respect to the first and second tread board support members 32 a and 32 b and the frame body 34. I support it.

  According to such a configuration, when the user going up and down the fixed staircase 2 lands on the tread board 33, the input vibration momentarily applied to the tread board 33 can be absorbed by the vibration isolator 50. For this reason, the vibration transmitted from the tread 33 to the first and second tread support members 32a and 32b can be reduced, and the shaking of the fixed step 31 cantilevered by the gantry 3 can be suppressed.

  In particular, when a plurality of fixing steps 31 are individually supported by the gantry 3, the vibration of one fixing step 31 is also transmitted to the other fixing steps 31 by solid propagation via the gantry 3, so that the vibration isolator 50 The vibration countermeasure using can be an effective means for suppressing the entire shaking of the fixed staircase 2.

  FIG. 8 discloses a third embodiment of the present invention.

  The third embodiment is different from the first embodiment in that the intermediate portion 39b of the second tread support member 32b is rotatably connected to the step receiving member 18b of the right truss 11. . Other configurations of the escalator 1 and the fixed staircase 2 are the same as those in the first embodiment. Therefore, in the third embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 8, the fitting hole 37 of the step receiving member 18b has a larger opening shape than the intermediate portion 39b of the second tread board support member 32b. Therefore, a gap g is formed between at least the upper surface of the intermediate portion 39b and the upper edge of the opening of the fitting hole 37 that can allow the second tread support member 32b to rotate.

  Further, the intermediate portion 39b of the second tread board support member 32b is supported via a pivot 60 so as to be rotatable. The pivot 60 extends horizontally along the depth direction of the tread 33 so as to be orthogonal to the second tread support 32b.

  For this reason, the second tread support material 32b is supported so as to be rotatable in the vertical direction of the gantry 3 with the pivot 60 as a fulcrum with respect to the step receiving material 18b.

  According to such a configuration, when a user going up and down the fixed staircase 2 lands on the tread 33, the second tread support 32 b is moved clockwise about the pivot 60 as indicated by an arrow in FIG. 8. A force to rotate is applied. For this reason, much of the load resulting from the weight of the fixed step 31 and the weight of the person who has entered the fixed step 31 can be positively transmitted to the left truss 10 on the side opposite to the fixed staircase 2 as a moment force.

  Therefore, although the fixed staircase 2 is supported on the right side of the gantry 3 in a cantilever state, the load transmitted from the fixed stairs 2 side to the gantry 3 can be distributed to both the left truss 10 and the right truss 11. it can. Therefore, the load burden of the right truss 11 adjacent to the fixed staircase 2 can be reduced, and the torsion of the gantry 3 can be reliably prevented.

  As a result, the degree of reinforcement of the gantry 3 can be reduced, the structure of the gantry 3 is simplified correspondingly, and the weight of the gantry 3 can be reduced. At the same time, the number of welding steps when assembling the gantry 3 can be reduced, which contributes to a reduction in manufacturing costs of the gantry 3.

  Further, it is not necessary to increase the height dimension (depth dimension) of the gantry 3 in order to ensure the section modulus of the gantry 3. As a result, it is possible to cope with the gantry 3 having a standard height dimension (depth dimension), and the design of the escalator 1 is improved.

  9 and 10 disclose a fourth embodiment of the present invention.

  The fourth embodiment is different from the first embodiment in that the intermediate portion 39b of the second tread support member 32b is movably connected to the step receiving member 18b of the right truss 11. Other configurations of the escalator 1 and the fixed staircase 2 are the same as those in the first embodiment.

  As shown in FIGS. 9 and 10, the fitting hole 37 of the step receiving member 18b has an opening shape that is slightly larger than the intermediate portion 39b of the second tread support member 32b. Therefore, a gap 70 that is continuous in the circumferential direction of the intermediate portion 39 b is formed between the outer peripheral surface of the intermediate portion 39 b and the inner peripheral surface of the fitting hole 37.

  According to such a configuration, the second tread plate support member 32b penetrates the step receiving member 18b without contacting the step receiving member 18b of the right truss 11, and the step receiving member 18b is provided by the gap 70. It is held in a movable state.

  For this reason, when a user going up and down the fixed staircase 2 lands on the tread board 33, a force is applied to move the second tread board support member 32b downward with the fixed end 39a as a fulcrum. Thereby, most of the load resulting from the weight of the fixed step 31 and the weight of the person who has entered the fixed step 31 can be positively transmitted to the left truss 10 located on the opposite side of the fixed staircase 2 as a moment force. .

  Therefore, as in the third embodiment, the load transmitted from the fixed staircase 2 side to the gantry 3 can be distributed to both the left truss 10 and the right truss 11 to reliably prevent the gantry 3 from being twisted. it can.

  In addition, since the second tread support material 32b only passes through the fitting hole 37 of the step receiving material 18b, the structure is simple and the number of parts of the gantry 3 can be reduced. At the same time, since there is a gap 70 between the inner peripheral surface of the fitting hole 37 and the outer peripheral surface of the second tread board support member 32b, the second tread board support member 32b is easily passed through the fitting hole 37. be able to. For this reason, the workability | operativity at the time of attaching the fixed staircase 2 to the mount frame 3 becomes favorable.

  FIG. 11 discloses a fifth embodiment of the present invention.

  The fifth embodiment is related to the fourth embodiment. In the fifth embodiment, the lower surface of the intermediate portion 39b of the second tread plate support member 32b penetrating the fitting hole 37 of the step receiving member 18b is welded to the step receiving member 18b.

  More specifically, the step receiving member 18b has an outer surface 80a that faces the fixed staircase 2, and an inner surface 80b that is located on the opposite side of the outer surface 80a. The outer side surface 80a of the step receiving member 18b is positioned so as to be orthogonal to the lower surface of the intermediate portion 39b of the second tread board support member 32b, and welding is performed between the outer side surface 80a and the lower surface of the intermediate portion 39b. A bead 81a is formed.

  Similarly, the inner side surface 80b of the step receiving member 18b is positioned so as to be orthogonal to the lower surface of the intermediate portion 39b of the second tread plate support member 32b, and between the inner side surface 80b and the lower surface of the intermediate portion 39b. A weld bead 81b is formed across the bridge.

  Accordingly, the intermediate portion 39b of the second tread plate support member 32b is welded to the step receiving member 18b of the right truss 11 from below the gantry 3, and the welding direction of the second tread plate support member 32b with respect to the step receiving member 18b. Is limited to one direction.

  Further, in the present embodiment, a gap 70 that allows movement of the second tread plate support member 32b between the outer peripheral surface of the intermediate portion 39b of the second tread plate support member 32b and the inner peripheral surface of the fitting hole 37. Is left as it is.

  According to such a configuration, the intermediate portion 39b of the second tread board support member 32b is stopped at its lower surface welded to the step receiving member 18b. There is a gap 70 between the peripheral surface. In other words, the second tread board support member 32b is not firmly fixed to the step receiving member 18b so as not to move, but is maintained in a temporarily fixed state that allows a certain amount of movement.

  For this reason, when the user who goes up and down the fixed stairs 2 lands on the tread 33, the second tread support 32 b tries to move within the gap 70 around the fixed end 39 a as a fulcrum due to the impact. Therefore, as in the fourth embodiment, the left side of the fixed step 31 is located on the opposite side of the fixed staircase 2 as a moment force with much of the load caused by the weight of the fixed step 31 and the weight of the person getting on the fixed step 31. The truss 10 can be actively communicated.

  Therefore, the load transmitted from the fixed staircase 2 side to the gantry 3 can be distributed to both the left truss 10 and the right truss 11 to reliably prevent the gantry 3 from being twisted.

  Further, the second tread plate support member 32b is temporarily fixed to the step receiving member 18b in such a form that it is supported from below by the weld beads 81a and 81b. Therefore, when a user who goes up and down the fixed staircase 2 lands on the tread board 33, vibration transmitted from the tread board 33 can be received by the step receiving member 18b. Therefore, especially in comparison with the fourth embodiment, it is possible to suppress the shaking of the fixing step 31 that is cantilevered by the gantry 3.

  In addition, since the lower side of the second tread support material 32b is widely opened, the welding operation of the second tread support material 32b to the step receiving material 18b can be easily performed.

  In the fifth embodiment, the second tread plate support member 32b is welded to the step receiving member 18b from below the gantry 3. However, the present invention is not limited to this, and the second tread plate support member 32b may be welded to the step receiving member 18b from above the gantry 3.

  12 and 13 disclose a sixth embodiment of the present invention.

  The sixth embodiment is related to the fourth embodiment. In the sixth embodiment, a ring-shaped vibration isolator 90 is interposed between the intermediate portion 39b of the second tread board support member 32b and the fitting hole 37 of the step receiving member 18b. The vibration isolator 90 is formed of a rubber-like elastic body, and is in contact with the outer peripheral surface of the intermediate portion 39 b and the inner peripheral surface of the fitting hole 37. Therefore, the vibration isolator 90 elastically supports the second tread support material 32b with respect to the step receiving material 18b.

  According to such a configuration, when a user going up and down the fixed staircase 2 lands on the tread 33, the tread 33 is instantaneously transferred to the step receiving member 18 b of the right truss 11 via the second tread support material 32 b. The applied input vibration can be absorbed by the vibration isolator 90. For this reason, the vibration transmitted to the right truss 11 can be mitigated, and the shaking of the fixing step 31 that is cantilevered by the gantry 3 can be suppressed.

  In particular, when a plurality of fixing steps 31 are individually supported by the gantry 3, the vibration of one fixing step 31 is also transmitted to the other fixing steps 31 by solid propagation via the gantry 3. The vibration countermeasure using can be an effective means for suppressing the entire shaking of the fixed staircase 2.

  FIG. 14 discloses a seventh embodiment of the present invention.

  In the seventh embodiment, the positional relationship between the fixing step 31 and the gantry 3 is different from that of the first embodiment. Other basic configurations of the escalator 1 and the fixed staircase 2 are the same as those in the first embodiment.

  As shown in FIG. 14, a plurality of step receiving members 100 (only one is shown) are welded across the upper main chord member 12 and the lower main chord member 13 of the left truss 10. The step receiving material 100 overlaps with the vertical beam 14 of the left truss 10 inside the left truss 10.

  Similarly, a plurality of step receiving members 101 (only one is shown) are welded between the upper main chord member 15 and the lower main chord member 16 of the right truss 11. The step receiving material 101 overlaps the vertical beam 17 of the right truss 11 inside the right truss 11.

  The fixing step 31 has a pair of tread support members 102 (only one is shown) that supports the tread 33. The tread board support members 102 have, for example, a bar shape having a square cross-sectional shape, and are arranged in parallel to each other with a space in the front-rear direction of the tread board 33.

  The tread board support member 102 has an extension 103 that extends coaxially inside the gantry 3. The extension 103 has such a length as to straddle between the vertical beam 14 of the left truss 10 and the vertical beam 17 of the right truss 11. Therefore, the tread board support member 102 including the extension portion 103 includes a fixed end 104 a located on the opposite side of the tread board 33, and an intermediate portion 104 b located between the fixed end 104 a and the tread board 33. The fixed end 104 a is defined by the tip of the extension portion 103. The intermediate portion 104 b is defined by the starting end of the extension portion 103.

  The intermediate portion 104 b of the tread board support member 102 continuously passes through the through hole 105 formed in the vertical beam 17 of the right truss 11 and the through hole 106 formed in the step receiving member 101. As a preferred example, a vibration isolator 108 is interposed between the outer peripheral surface of the intermediate portion 104 b and the inner peripheral surfaces of the through holes 105 and 106. The vibration isolator 108 is made of, for example, a rubber-like elastic body, and elastically supports the intermediate portion 104 with respect to the right truss 11 by contacting the outer peripheral surface of the intermediate portion 104b and the inner peripheral surfaces of the through holes 105 and 106. is doing.

  The fixed end 104 a of the tread board support member 102 is fitted in a fitting hole 109 opened in the vertical beam 14 of the left truss 10 and a fitting hole 110 opened in the step receiving member 100. The fitting portion between the fixed end 104a and the fitting holes 109 and 110 is firmly fixed by means such as welding. Accordingly, the tread board support member 102 horizontally supports the tread board 33 by projecting horizontally from the left and right trusses 10 and 11 toward the right side of the gantry 3.

  Furthermore, the extension 103 of the tread support material 102 that advances into the gantry 3 extends between the left and right trusses 10 and 11 through the gap G between the forward path 23a and the return path 23b of the movable step row 23. .

  According to such a configuration, since the tread support material 102 straddling between the left and right trusses 10 and 11 passes between the forward path 23a and the return path 23b of the movable step row 23, the step receiving materials 100 and 101 and the tread board The support material 102 does not protrude below the gantry 3.

  For this reason, the height dimension (depth dimension) of the gantry 3 can be kept small, which is an advantageous configuration for improving the design of the escalator 1.

  In the seventh embodiment, the step receiving members 100 and 101 are superposed on the vertical beams 14 and 17 of the gantry 3, but by increasing the thickness of the vertical beams 14 and 17, the steps are placed on the vertical beams 14 and 17. The functions of the receiving materials 100 and 101 may be combined.

  According to this configuration, the step receiving materials 100 and 101 can be omitted, and the number of parts of the gantry 3 can be reduced.

  FIG. 15 discloses an eighth embodiment of the present invention.

  In the eighth embodiment, the configuration of the fixed staircase 2 is different from that of the first embodiment. As shown in FIG. 15, the frame body 34 of each fixing step 31 has a rear frame portion 120 located behind the first tread plate support plate 32a. The rear frame portion 120 extends along the length direction of the tread plate 33, and projects below the fixed step 31 positioned one step above the rear frame portion 120.

  A connecting material 121 made of, for example, tempered glass is interposed between the upper surface of the rear frame portion 120 of each fixing step 31 and the bottom plate 35 of the fixing step 31 positioned one step higher than the rear frame portion 120. The connecting member 121 stands from the upper surface of the rear frame portion 120 so as to fill a gap between the adjacent fixing steps 31. The lower end of the connecting member 121 is fixed to the upper surface of the rear frame portion 120, and the upper end of the connecting member 121 is fixed to the lower surface of the bottom plate 35.

  Therefore, the plurality of adjacent fixing steps 31 having steps in the vertical direction are integrally coupled via the plurality of connecting members 121.

  According to such a configuration, between the plurality of adjacent fixing steps 31 are integrally coupled via the connecting member 121, the rigidity of the fixed staircase 2 is improved. Therefore, although the fixing step 31 is supported in a cantilever state on the mount 3 of the escalator 1, it is possible to reduce the shaking of the fixing step 31 when a person goes up and down the fixing stairs 2.

  In other words, when a user going up and down the fixed staircase 2 lands on the tread board 33, an impact applied to the fixed step 31 can be released to the adjacent fixed step 31 via the connecting member 121. As a result, the swing of the fixed step 31 can be attenuated by using the adjacent fixed step 31, and the swing of the solid staircase 2 can be suppressed.

  FIG. 16 discloses a ninth embodiment of the present invention.

  The ninth embodiment differs from the first embodiment in the configuration of the second support fitting 8 of the gantry 3. FIG. 16 is a plan view of the base 3 and the fixed staircase 2 of the escalator 1 as viewed from above.

The tip of the extension 130 is located at the end opposite to the gantry 3. The connecting part 131 extends in a straight line from the tip of the extension part 130 along the arrangement direction of the fixing steps 31. Therefore, the extension part 130 and the connection part 131 maintain a positional relationship such that they are orthogonal to each other, and the second support fitting 8 is bent into an L shape when the man conveyor system is viewed from above.

  The connecting portion 131 passes under the fixed step row 23 and reaches the fixed step 31 whose lower end is positioned at the lowermost stage of the fixed step 2. Further, the connecting portion 131 is connected to the tip of the fixing step 31 on the side opposite to the gantry 3 by means such as welding or bolting. Therefore, the adjacent fixing steps 31 having a step in the vertical direction are integrally coupled via the connecting portion 131.

  According to such a configuration, the tip portions of the plurality of fixing steps 31 positioned on the opposite side of the gantry 3 are integrally coupled via the connecting portion 131 of the second support fitting 8. The rigidity of the stairs 2 is improved. For this reason, when a user going up and down the fixed staircase 2 lands on the fixed step 31, an impact applied to the fixed step 31 can be released to the adjacent fixed step 31 via the connecting portion 131. As a result, similarly to the eighth embodiment, the swing of the fixed step 31 can be attenuated by using the adjacent fixed step 31 and the swing of the solid staircase 2 can be suppressed.

  Furthermore, according to the above configuration, the second support fitting 8 that is a constituent element of the gantry 3 extends toward the fixed step 31 positioned at the uppermost stage of the fixed staircase 2 and is connected to the fixed staircase 2. For this reason, the rigidity of the second support fitting 8 is improved, and the twist of the second support fitting 8 can be reduced while the fixed staircase 2 is attached to the gantry 3.

The second fixed staircase 141 is supported in a cantilevered state on the right truss 11 of the inclined portion 6. For this reason, the first and second fixed stairs 140 and 141 are arranged so as to be laterally distributed with the mount 3 of the escalator 1 interposed therebetween.

  In the tenth embodiment, the configuration of the first and second fixed steps 140 and 141 and the support structure of the first and second fixed steps 140 and 141 with respect to the gantry 3 are the same as those in the first embodiment.

Therefore, the first extension portion 155 includes a fixed end 157 a located on the opposite side of the tread plate 33 and an intermediate portion 157 b located between the fixed end 157 a and the tread plate 33. The fixed end 157 a is defined by the tip of the first extension 155. The intermediate portion 157 b is defined by the starting end of the first extension portion 155.

  The intermediate portion 157 b of the first extension portion 155 passes through the fitting hole 37 of the step receiving member 18 b of the right truss 11. A gap 158 that is continuous in the circumferential direction is formed between the outer peripheral surface of the intermediate portion 157 b and the inner peripheral surface of the fitting hole 37. The fixed end 157 a of the first extension 155 is fitted in the fitting hole 40 opened in the step receiving member 18 a of the left truss 10. The fitting portion between the fixed end 157a and the fitting hole 40 of the step receiving member 18a is firmly fixed by means such as welding.

  The second extension 156 has such a length as to straddle between the step receiving member 18 a of the left truss 10 and the step receiving member 18 b of the right truss 11. Therefore, the second extension portion 156 includes a fixed end 160 a located on the opposite side of the tread plate 33 and an intermediate portion 160 b located between the fixed end 160 a and the tread plate 33. The fixed end 160 a is defined by the tip of the second extension 156. The intermediate portion 160 b is defined by the starting end of the second extension portion 156.
