Embodiment
With reference to Fig. 1 and 2, there is provided with rescuing lowering means（RDD）12 are used together to allow user from elevated structure
（High-storey, drilling platforms, windmill platform or public utilities pylon in such as mansion）The descending system 10 safely declined.Although
Particular configuration is shown, but RDD 12 can be any appropriate rescue lowering means or control lowering means, many of which
Be it is known, one be by Honeywell with Miller SafEscape ELITE trademark Soynattos, another example be by
DBI/Sala is with Rescuematic Automatic Descent Controller trademark Soynattos.
Descending system 10 is included to receive the safety line spool 14 of one section of safety line 16, and the safety line 16 is being opened up
Open and be wrapped under ready condition around spool 14.Safety line spool 14 is installed to rigid frame 20 so as to around axis 22
Rotate to allow as RDD 12 provides controlled decline to the user for being tethered to safety line 16 and allows this section of safety line
16 are deployed into RDD 12 from spool 14.System 10 also includes friction mechanism 24, its be installed to rigid frame 20 and with rope 16
Friction load is generated to allow to pacify to be extended to RDD 12 with safety line 16 with least one engagement in spool 14
Full rope 16 is deployed into RDD 12 from spool 14 in a controlled manner.In this respect, the combination of the anti-locking system 10 of friction mechanism 24
Quality（Including safety line 16）When framework 20, spool 14 and safety line 16 are dropped by user from elevated position with height
Speed declines.Friction mechanism 24 should allow the sufficiently low speed of spool 14, framework 20 and safety line 16 so that positioned at making
People below user is as safety line 16 is by from declining spool 14 and framework 20 spreads across RDD 12 to being tethered to
The user of the brace of link 25 on the end of safety line 16 will not be hurt by spool 14 and framework 20.In this side
Face, link 25 can be that any appropriate fall protection connects, such as lifting-hook or suspension hook.System 10 also includes being fixed on framework
In so that safety line is guided to RDD 12 safety line guiding piece 26 from spool.As being seen best in fig. 2, scheming
In 1-3 embodiment, safety line guiding piece 26 is the framework for being spaced apart and being sized to receive safety line with spool
In hole 27.
In the embodiment of Fig. 1-3, friction mechanism 24 includes the He of a pair of frictional disks 28 most preferably seen in figures 4 and 5
30, disk 28 is fixed on spool 14 to rotate therewith, and another disk 30 is fixed on framework 20 against rotation.
As most preferably seen in Figure 5, disk 30 includes friction surface 32, and it is engaged against on the disk 28 that is rotated together with spool
Surface 34, it is resulting to rub for allowing safety line being deployed into RDD 12 from spool in a controlled manner.In this respect,
Any appropriate means can be used（Such as via appropriate disk or helical spring mechanism）Or by for the He of holding tray 28
30th, surface 32 and 34 is caused to abut one another any other appropriate means being preloaded and disk 28 and 30 abut one another into pre-add
Carry.
In the embodiment of Fig. 1-3, framework 20 includes a pair of supporting legs 36 being relatively spaced apart, and it is from cross member 38
Extend to axis 22 and realize rotation to install spool 14.Cross member 38 limits safety line guiding piece in the form of hole 27
26。
As most preferably seen in figs. 6 and 7, in another embodiment of system 10, friction mechanism 24 forms safety rope
Guiding element 26 is indexed, and including three parallel bars 40,42 and 44, it is installed to framework 20 and is spaced apart with spool 14, bar 40,
42 and 44 extend in common plane.Safety line 16 passes through bar 40,42 and 44 so that each bar frictionally engages safety line
16, and safety line 16 must be deployed with it from system 10 and around bar " bending ".In the embodiment shown, bar 42
Be installed in a pair of slits 46, its relative to axis 22 radially, and allow bar 42 relative to axis 22 radially
It is mobile, with adjustment as safety line 16 is deployed and the friction load in face placed on it from system 10.
In Fig. 6 and 7 embodiment, framework 20 includes a pair of supporting legs 48 being relatively spaced apart, and it is by the phase of bar 40 and 44
It is mutually fixed and extend to the axis 22 of spool 14 from bar 40 and 44 so that spool 14 is rotatably mounted into framework 20.
In the embodiment shown, spool 14 includes that the wheel hub 50 of safety line can be wound around it and to take turns
A pair of spaced radially extending walls 52 and 57 of safety line are included on hub.Any appropriate means can be used（Such as with
A pair of rotatable bearings spaced apart（It is not shown）Wheel shaft）Wheel hub is installed to rigid frame to realize rotation.
In operation, RDD 12 anchors to stationary structure, and framework 20 and spool at elevated position by user
14 is empty from elevated position by user after the safety line 16 that the brace of user has been connected at link 25 by user
Throw.User then by their own from safety line 16 hang out come, while RDD with safety line 16 by a controlled manner from
Spool 14 is deployed into RDD 12 and provides the controlled decline of user.In this respect, it should be appreciated that system 10 can reach " flat
Weigh point ", wherein, framework 20 and spool 14 decline no longer as rope 16 is extended to RDD 12.
It should be appreciated that installing the framework 20 of spool 18 together with friction mechanism 24 by providing, descending system 10 is permitted
Perhaps using rescue lowering means, such as RDD 12, without requiring the length of the relatively long of safety line 16 and weight with uncontrolled
Mode is dropped downwards from the user position on elevated structure, and is pointed to so as to eliminate below the elevated position of user
People potential danger.Furthermore, it is to be understood that be that framework 20 and spool 14 simplify user and carried out during emergency
RDD 12 use because its make system 10 component shortly can be used under the conditions of occur.
It is understood that while the particular form for each component has been disclosed herein, but in the scope of the present disclosure
It is interior to be contemplated that using the other appropriate formats for being used for open structure.
