Fig. 4 is the enlarged side view of the extrusome 24 illustrating Fig. 2.In addition, Fig. 5 is the main view of the extrusome 24 illustrating Fig. 4
Figure.Extrusome 24 has：The support member 26 of tabular, it is provided with elongated hole (guide portion) 25；Ratchet (engaging part) 27, its quilt
Elongated hole 25 guides and shifts with respect to support member 26；A pair of friction member 28, they are clamped in support member 26 and ratchet
Between 27, produce frictional force between support member 26 and integratedly shift with ratchet 27；And multiple (be in this example
2) securing member 29, ratchet 27 is held in support member 26 in the way of can shifting by they.
Extrusome 24 is stretched with respect to the displacement of support member 26 by ratchet 27.That is, the state of extrusome 24 is passed through
Ratchet 27 with respect to support member 26 displacement and extrusome 24 length reach set upper length limit L1 elongation state with
The length of extrusome 24 reaches the anaplasia of the deflated state of setting lower limit length L2 (L2 ＜ L1) shorter than setting upper length limit L1
Change.When extrusome 24 engages and shrinks with the tooth 21a of the peripheral part of ratchet 21, each friction member 28 and support member 26 it
Between produce frictional force become the resistance contrary with the revolving force of ratchet 21.
Support member 26 is fixed in rotary shaft 22 with the state configuring perpendicularly to the axis with respect to rotary shaft 22.As figure
Shown in 4, elongated hole 25 being radially disposed in support member 26 along rotary shaft 22.
Ratchet 27 has the opposed plate of opposite each other a pair 271 and the pin (engaging being fixed between a pair opposed plate 271
Piece) 272.
A pair opposed plate 271 is the plate of the length direction configuration along elongated hole 25.In addition, a pair opposed plate 271 is respective
Length is longer than the length of elongated hole 25.And, each opposed plate 271 projects from support member 26 on the length direction of elongated hole 25.
As shown in figure 5, support member 26 is held between a pair opposed plate 271 across a pair of friction member 28.Each opposed
Plate 271, each friction member 28 and support member 26 are fastened by collective by each securing member 29.Ratchet 27, each friction member 28 and
Each securing member 29 shifts with respect to support member 26 one.
Between each friction member 28 and support member 26, frictional force is produced due to the fastening of each securing member 29.Thus, one
Opposed plate 271 is accepted with the frictional force producing between each friction member 28 and support member 26 as resistance and with respect to support
Part 26 shifts.The size of the frictional force producing between each friction member 28 and support member 26 is passed through to be based on for example each step 3
The size of fastening force to adjust each securing member 29 such as weight and be adjusted.
Each securing member 29 has run through bolt 291 and nut 292, wherein, this run through bolt 291 be each passed through elongated hole 25,
The bolt hole (circular hole) that is arranged on each opposed plate 271 and be arranged at bolt hole (circular hole) on each friction member 28, should
Nut 292 is screwed together in the threaded portion of run through bolt 291, and by each opposed plate 271, each between the head of run through bolt 291
Friction member 28 and the fastening of support member 26 collective.Slided in elongated hole 25 by making each run through bolt 291, a pair opposed plate
271 are guided by the length direction to elongated hole 25.
Each securing member 29 configures on the length direction of elongated hole 25 separated from each other.Thus it is therefore prevented that each opposed plate 271 phase
Support member 26 is rotated, and maintains the length direction of each opposed plate 271 shape consistent with the length direction of elongated hole 25
State.
When the length of extrusome 24 reaches setting lower limit length L2 (that is, extrusome 24 becomes deflated state), run through spiral shell
Bolt 291 is sticked in the end (length direction one end) of the side close to rotary shaft 22 of elongated hole 25.Thus, stop ratchet 27 to
The direction displacement that extrusome 24 shrinks.In addition, when the length of extrusome 24 reaches setting upper length limit L1, (that is, extrusome 24 becomes
For elongation state) when, run through bolt 291 is sticked in the end of the side away from rotary shaft 22 of elongated hole 25, and (length direction is another
End).Thus, ratchet 27 is stoped to shift to the direction that extrusome 24 extends.That is, the length direction one end of elongated hole 25 is as resistance
Only the retainer of the direction displacement that ratchet 27 shrinks to extrusome 24 is arranged in support member 26, and the length direction of elongated hole 25 is another
One end is arranged in support member 26 as the retainer of the direction displacement stoping ratchet 27 from extending to extrusome 24.Extrusome
24 scalable scope (setting upper length limit L1 and the difference setting lower limit length L2) is the impact considering to produce on step 3
Size and determine.
Pin 272 is fixed between the end of the side away from rotary shaft 22 of a pair opposed plate 271.Thus, the position of pin 272
Become the position away from rotary shaft 22 than support member 26.From rotary shaft 22 to the distance of pin 272 according to ratchet 27 along elongated hole 25
Length direction shift with respect to support member 26 and change.That is, work as extrusome with regard to from rotary shaft 22 to the distance of pin 272
24 is maximum during elongation state, minimum when extrusome 24 is deflated state.
When extrusome 24 is displaced to clamped position under elongation state, the tooth 21a card of the peripheral part of pin 272 and ratchet 21
Close.In the state of the tooth 21a of the peripheral part of ratchet 21 is engaged with pin 272, pin 272 accepts revolving force from ratchet 21, thus spine
Pawl 27 resists the frictional force producing between each friction member 28 and support member 26 and to pin 272 close to the direction of rotary shaft 22
Displacement.
Then, action is illustrated.Fig. 6 is to illustrate that the extrusome 24 of Fig. 2 is present in the amplification of the state releasing position
Side view.During normal operation, the slide mass 23b of detection bar 23 is placed in drive chain 14.Now, as shown in Figure 2 and Figure 6,
The position of extrusome 24 is held in releasing position detached from ratchet 21, and the state of extrusome 24 becomes elongation state.Thus, hold
Permitted the rotation of ratchet 21.
When running well, when the driving machine sprocket wheel 10 of driving machine 6 is rotated by the control of control device, drive chain
Bar 14 is rotated around in the state of slide mass 23b is placed in drive chain 14.Thus, main shaft 11, drive sprocket 12,
Top ladder sprocket wheel 13 and ratchet 21 integratedly rotate, and step 3 and mobile handrail 5 are mutually in step and mobile.
Fig. 7 is that the extrusome 24 illustrating Fig. 6 is displaced to the enlarged side view of the state of clamped position.When generation drive chain
During the exception of 14 disconnections, detection bar 23 is integratedly rotated with extrusome 24 by deadweight.Thus, extrusome 24 is from releasing position
It is displaced to clamped position, as shown in fig. 7, the pin 272 of extrusome 24 is engaged with the tooth 21a of the peripheral part of ratchet 21.
Fig. 8 be illustrate the ratchet 21 of Fig. 7 engage with pin 272 and extrusome 24 become deflated state state side-looking

When the direction that the step 3 of the position of passenger declines rotates, pin 272 is pushed away to close to the direction of rotary shaft 22 by the tooth 21a of ratchet 21
Press, and ratchet 27 shifts with respect to support member 26 along elongated hole 25, thus, the state of extrusome 24 becomes contracting from elongation state
Little state.Now, ratchet 27 is resisted the frictional force producing between each friction member 28 and support member 26 and is shifted.Thus, to
Ratchet 21 and chain gear apparatus 7 apply brake force, and the rotation of ratchet 21 and chain gear apparatus 7 stops.When the rotation of chain gear apparatus 7 stops
When, the mobile stopping of step 3.
In such safety device 8, when extrusome 24 is displaced to the engaging engaging with the tooth 21a of the peripheral part of ratchet 21
During position, because producing the resistance contrary with the revolving force of ratchet 21, and extrusome 24 shrinks, therefore, it is possible to by extrusome
Resistance during 24 contraction prevents the rotary speed of ratchet 21 from drastically reducing.Thus, forcibly make spine when in escalator exception
When wheel 21 stops, the impact producing can be relaxed on ratchet 21, and the impact that the stopping of step 3 causes can be relaxed.In addition,
Because simple for structureization of the ratchet 21 as the part bigger than extrusome 24 can be made, and the structure of extrusome 24 is also letter
