1-4 < act >
Then, the movement of brake apparatus 1000 involved in present embodiment is illustrated using Figure 18.In Figure 18 (a)
It is the state (normal condition) for not applying any tension to rope CD, is (b) tension to be applied to rope CD and with knurling roller 240 and roller
The state (clamp position) of the clamping of portion 42 rope CD, (c) be from the state of (a) in Figure 18 into Figure 18 when the state change of (b)
The summary figure of the direction of rotation of each component.In addition, (a) of Figure 18, (b) are identical as Figure 16, it is all the line A-A cutting of (c) in Fig. 4
The cross-sectional view in portion.Here, the periphery of roller portion 42 not shown in the cross-sectional view is overlapped in central spindle 41 for the reason in explanation
Around and indicate, the periphery of knurling roller 240 is overlapped in around central spindle 31 and indicates.In addition, the periphery of knurling roller 240 is not
Stringent circle, but in order to illustrate simplification illustrated with approximately round.
In Figure 18 shown in (a), in normal state, as described above, the inner wall at the rear of helical spring SP and shell 10A
It abuts, sliding block 220 is pushed forwards.Therefore, sliding block 220 is located at the front of shell 10A.Pass through the first of sliding block 220 as a result,
Roof slot 226 and the first bottom wall slot 228 and limited the central spindle 31 of position and by the second roof slot 227 and the second bottom wall
Slot 229 and limited the central spindle 41 of position, moved forwards together with sliding block 220.In turn, it is held in 220 top of sliding block
Shell 10A in set the first roof slot 16 and the second roof slot 17, as the distance mutual towards front becomes
It is small.Similarly, the first base seat groove 706 and the second base seat groove 707 set in pedestal 70, with towards front and it is mutual
Distance become smaller.Therefore, it is supported in the roller portion 42 of central spindle 41 in a manner of it can rotate and is supported in a manner of it can rotate
The distance between knurling roller 240 of central spindle 31 also becomes smaller.That is, the first roof slot 16 and the first base seat groove 706 are sent out as limiting groove
The effect of waving, the limiting groove and the central spindle 31 of knurling roller 240 in can it is movably chimeric thus limit knurling roller 240 can only along slot into
Row movement.Similarly, the second roof slot 17 and the second base seat groove 707 play a role as limiting groove, the limiting groove and roller portion 42
Central spindle 41 in can movably be fitted into limit roller portion 42 and can only be moved along slot.In addition, the first top when due to overlooking
Wall trench 16 and the first base seat groove 706 and the central point of the inner peripheral surface of the tooth rest 260 with internal tooth are formed on concentric circles, therefore,
Even if central spindle 31 moves in each slot, pinion gear 50 can also continue and the internal tooth that is arranged on the tooth rest 260 with internal tooth
261 engagement of wheel.
In this way, knurling roller 240 is pushed by roller portion 42 when the distance between knurling roller 240 and roller portion 42 become smaller, CD quilt of restricting
Knurling roller 240 and roller portion 42 clamp.That is, in the present embodiment, helical spring SP is also as always to the application work of knurling roller 240
Force application part firmly plays a role, so that knurling roller 240 is pushed by roller portion 42.
Moreover, applying tension towards the direction (front) of arrow D1 to rope CD in the brake apparatus 1000 of normal condition.
Then, using the frictional force generated between rope CD, knurling roller 240 is rotated counterclockwise, and roller portion 42 is rotated clockwise.
Then, by the rotation of knurling roller 240, with its share identical central spindle 31 and fixed pinion gear 50 also towards and knurling roller
240 identical direction rotations (rotation) (counterclockwise).At this point, as shown in (b) in Figure 18, direction when central spindle 31 and central spindle 41 are overlooked
Front is mobile, and close to each other in the lateral direction, and the chucking power of knurling roller 240 and 42 couples of roller portion rope CD become strong, thus according to
Restrict CD movement and knurling roller 240 is reliably rotated.Then, it is engaged due to pinion gear 50 with internal gear 261, benefit
With the power of the tooth application by pinion gear 50, internal gear 261 is rotated (rotation) counterclockwise.As a result, due to the gear with internal tooth
Frame 260 is also rotated (rotation) with internal gear 261 counterclockwise together, therefore, the row on the tooth rest 260 with internal tooth is arranged in
Star gear 280 is similarly rotated (revolution) counterclockwise.Here, due to planetary gear 280 and by sun gear 323 and shell
Body 10A fixed inner circumferential gear 115 is intermeshed, and therefore, is become towards direction (clockwise) rotation contrary with revolving,
Simultaneously to revolve counterclockwise.Therefore, the sun gear 323 engaged with planetary gear 280 in the inside of planetary gear 280 towards with
Rotation (rotation) that the opposite direction of the rotation of planetary gear 280 is (counterclockwise).At this point, using planetary gear 280, sun gear
323 rotation is by speedup.It is kept on the balance weight bracket 320 with sun gear rotated together with as a result, with sun gear 323
Balance weight 340 also start to rotate.In addition, as has been described, being engaged in the outside of planetary gear 280 with planetary gear 280
Inner circumferential gear 115 since shell 10A and pedestal 70 are fixed, even if planetary gear 280 rotate when, inner circumferential gear 115
It will not rotate.
Moreover, as shown in (b) in Figure 18, when knurling roller 240 and roller portion 42 are close to boundary (clamp position), knurling roller
240 continue rotations, but knurling roller 240 along internal gear 261 moves stopping.At this point, by knurling roller 240 it is geostrophic its
The rotation of his component is also continuing.Then, balance weight 340 is abutted using centrifugal force with the internal perisporium of shell 10A, thus to rotation
Generate resistance.That is, the movement speed rising by the CD that restricts rises revolving speed, thus centrifugal force increases.Moreover, passing through centrifugation
Power increases, and balance weight 340 is more strongly abutted with the internal perisporium of shell 10A, so that resistance increases.Thereby, it is possible to inhibit the CD that restricts
Movement speed (decrease speed of insolation curtain-shaped cover member).Here, being approximately fixed situation (example in the tension applied to rope CD
Such as, free by the insolation curtain-shaped cover member of suspension strut in a manner of it can go up and down on the rope CD of the front side of brake apparatus 1000
The case where falling bodies) under, when the tension applied to rope CD is equal with the resistance generated by the internal perisporium of balance weight 340 and shell 10A
When weighing apparatus, the movement speed for the CD that restricts becomes approximately fixed.Therefore, damping due to rotation of the brake apparatus 1000 as the movement for rope CD
Device plays a role, and insolation curtain-shaped cover member can be made slowly to decline.
(c) is that the clamp position variation for discussed above from normal condition to clamp position summarizes respectively in Figure 18
The figure of the direction of rotation (about pinion gear 50, and then further including the front-rear direction and fastening direction when overlooking) of component.
On the other hand, in the case where applying tension towards the direction (rear) opposite with arrow D1 to rope CD, knurling roller

The position of clip position before being moved past abrasion simultaneously clamps rope this state of CD in the clip position.
5. the 5th embodiment
Then, brake apparatus 5000 involved in the 5th embodiment is illustrated using Figure 28~Figure 34.This implementation
Brake apparatus 5000 involved in mode is formed as movement converter section DT and resistance assigning unit RA and configures side by side as shown in Figure 28 etc.
This composition.Hereinafter, the summary to present embodiment is illustrated.
As shown in Figure 28~Figure 30, movement converter section DT is constituted by grabbing roller (catch roller) 32A and grabbing roller 32B,
In, it grabs roller 32A and is made of inner cylinder 42A and outer cylinder 240A, grab roller 32B for so-called fixed pulley and by the side can rotate
Formula is mounted on the composition of the knurling roller 240 in central spindle 31.It is arranged on shell 440A in addition, grabbing roller 32A, 32B.Using grabbing roller
The rotational torque clamping rope CD of 32A, 32B.In addition, rope CD is inserted through movement converter section DT via rope insertion hole 14A.For grabbing
Roller 32A, is illustrated in more details later.
Resistance assigning unit RA is so-called centrifugal governor, and is following component: that is, balance weight 340A is with Figure 29 institute
It revolves centered on the damping shaft shown, when mobile to outer diameter side due to centrifugal force balance weight 340A, balance weight 340A and shell
Friction occurs for body 10Aa contact to generate this component of brake force.The rotary transfer machine for rotating balance weight 340A (is not schemed
Show) it is connect with the central spindle 31 for grabbing roller 32B, when grabbing roller 32B rotation, power involved in the rotation is via rotary transfer machine quilt
It is transferred to resistance assigning unit RA, thus balance weight 340A is revolved centered on damping shaft.The number of balance weight 340A does not have
Limitation, such as can be two, four, eight, 16.
Grab roller 32A composition are as follows: inner cylinder 42A and outer cylinder 240A can mutually be relatively rotated and be had in the relative rotation
Resistance to sliding.As shown in figure 31, it is constituted in such a way that the periphery of inner cylinder 42A is encased by outer cylinder 240A.For the situation, it is laggard
Row is described in detail.It is provided with rotary shaft 31B and guiding axis 31C on the side of inner cylinder 42A, is provided with rotary shaft on shell 440A
The guide groove 31Ca of the movement of the bearing and guidance guiding axis 31C of 31B.That is, grabbing roller 32A and being configured to and be with rotary shaft 31B
Center is rotated.Guide groove 31Ca makes to grab roller 32A with one side and the CD that restricts is close, the other side makes to grab roller 32A and rope CD is separate
Mode be arranged.In other words, guide groove 31Ca from side towards the other side to grab roller 32A and be formed from the separate mode of rope CD.
It here, guide groove 31Ca is equivalent to limiting groove in the 5th embodiment, and is more than cramping body (grab roller 32A and grab roller 32B)
Clip position under original state and extend.In addition, the circle in (a) of Figure 30 with dotted line illustrates defined clip position, with
Under explanation be to cramping body abrasion after movement be illustrated.
According to the above structure of guide groove 31Ca, when rope CD is moved towards in Figure 30 with the braking direction that arrow in scheming indicates
When, it grabs roller 32A and is rotated centered on rotary shaft 31B, be accompanied by this guiding axis 31C and moved along guide groove 31Ca.Here,
In guide groove 31Ca, by clamping guiding surface 31a, release guiding surface 31b, nip side limitation face 31c and release lateral confinement system
Face 31d forms inner peripheral surface.Moreover, the location of guiding axis 31C on the side of guide groove 31Ca shown in (a) of Figure 30
At (first position), the rotation for grabbing roller 32A is limited.In this state, rope CD is grabbed roller 32A, 32B clamping, when rope CD is into one
When step is mobile towards braking direction, the outer cylinder 240A for grabbing roller 32A is rotated relative to inner cylinder 42A, is grabbed roller 32B with central spindle 31 and is
Center is rotated.That is, using with grab the resistance assigning unit RA that roller 32B connect and assign resistance, thus the mobile progress to rope CD
Braking.
In addition, according to the above structure of guide groove 31Ca, when rope CD is towards the release side indicated in Figure 30 with arrow in scheming
To when movement, grabs roller 32A and rotated centered on rotary shaft 31B, be accompanied by this guiding axis 31C and moved along guide groove 31Ca.
At this point, movement (rotation) track for grabbing roller 32A is the track along guide groove 31Ca.In addition, as shown in (b) of Figure 30, it is mobile
Track is more than defined clip position and extends.In addition, the variation one~tri- of aftermentioned 5th embodiment is also identical, therefore
The illustration is omitted and explanation.
Moreover, the location of guiding axis 31C (second on the other side of guide groove 31Ca shown in (b) of Figure 30
Set) at, the rotation for grabbing roller 32A is limited.In this state, rope CD is not grabbed roller 32A, 32B clamping or only by with relatively weak
Power clamping keep the torque for grabbing roller 32B rotation also insufficient, to grab roller 32B not even if rope CD is further mobile to release direction
Rotation.Therefore, it is not endowed with the resistance applied by resistance assigning unit RA.
Summarize speech, during the state change of (b) into Figure 30 of the state from (a) in Figure 30, although by resistance
Assigning unit RA imparts resistance to rope CD, but resistance assigning unit RA does not play a role in the state of (b) of Figure 30.Moreover,
The distance between outer cylinder 240A and knurling roller 240 be than big in the state of (a) of Figure 30 in the state of (b) of Figure 30, therefore right
The chucking power of rope CD dies down.As a result, due to becoming the state being released to the rope CD brake force applied, it is achieved that rope CD
It moves freely.In turn, during the state change of (a) into Figure 30 of the state from (b) in Figure 30, by resistance assigning unit RA
Resistance is assigned to rope CD, resistance assigning unit RA plays a role while rope CD is clamped in the state of (a) in Figure 30.
In addition, as long as resistance to sliding when inner cylinder 42A and outer cylinder 240A relative rotation turns to first in guiding axis 31C
The resistance of the degree of relative rotation is unable to when position.In consideration of it, the inner cylinder 42A and outer cylinder 240A that grab roller 32A can be as follows
It constitutes.

Three > of variation of the 5th embodiment of <
Then, brake apparatus 5300 involved in the variation three using Figure 38~Figure 40 to the 5th embodiment is said
It is bright.Brake apparatus 5300 involved in this variation is formed as moving converter section DT and resistance assigns as shown in Figure 36 and Figure 37
The composition that portion RA is configured on (direction vertical with paper) side by side in left and right directions.Hereinafter, the summary to this variation is said
It is bright.
As shown in figure 38, movement converter section DT is constituted by grabbing roller 830 and grabbing roller 840, wherein grabs roller 830 by inner cylinder 830A
It is constituted with outer cylinder 830B, grabs roller 840 and have the knurling roller 43 being mounted in central spindle 41 in a manner of it can rotate.It is same as Figure 31
Ground, inner cylinder 830A and outer cylinder 830B are constituted are as follows: inner cylinder 830A is mounted in rotary shaft 831 in a manner of it can rotate, inner cylinder
830A and outer cylinder 830B from each other being capable of relative rotation and for providing that torque below carries out one rotation using resistance to sliding
Turn.But unlike Figure 31, the center for grabbing roller 830 is arranged in rotary shaft 831, and is supported by shell 810A axis.In addition,
From 831 eccentric position of rotary shaft, guiding axis 850 is protruded towards axial sides.In addition, in this variation, grabbing roller
840 as shown in figure 39, are maintained at the support for the mobile shell 820 that can be moved in parallel along the vertical direction in a manner of it can rotate
In slot 821 (referring to Figure 39).Here, in the present embodiment, constituting a pair of of hold assembly (cramping body) by grabbing roller 830 and 840.
In addition, in the present embodiment, resistance assigning unit RA is also to have centrifugal governor and by the rotation of rotary shaft 831
Turn be transferred to centrifugal governor and make its brake component, it is identical as above-mentioned variation two, grab the rotation of the outer cylinder 830B of roller 830
Turn to be passed to resistance assigning unit RA via pinion gear 50B (referring to Figure 37).It, can be appropriate about the composition of resistance assigning unit RA
Use documented composition in already described embodiment.
Mobile shell 820 has a pair of of the parallel-plate 822 for being formed in and grabbing roller 830,840 both ends, is formed on each parallel-plate 822
There is support slot 821 (referring to Figure 39).In addition, the centre in the front-back direction above parallel-plate 822 is formed with and opens upward

It is equivalent to limiting groove to slot 823, and is extended more than the clip position under the original state of cramping body (grabbing roller 830,840).Separately
Outside, the circle in (b) of Figure 38 with dotted line illustrates defined clip position, and the following description is to the movement after cramping body abrasion
It is illustrated.
Here, in this variation, in the case where not applying the state (normal condition) of tension to rope CD, such as (a) institute of Figure 38
Show, rope CD be configured to only be located above grab roller 830 contact, with grab roller 840 and do not contact.
Using composition as above, never make rope CD towards rear (Figure 38 the rope CD state (normal condition) for applying tension
Right) it is mobile when, the outer cylinder 830B for grabbing roller 830 is intended to towards counter clockwise direction (arrow X-direction) rotation in (a) of Figure 38,
But due to a pair of of hold assembly, grab roller 830,840 and do not clamp rope CD (also referring to (a) of Figure 39, (a) of Figure 40),
Rope the mobile of CD fails sufficiently to transmit as the rotation for grabbing roller 830 (outer cylinder 830B), so that the rotation of outer cylinder 830B will not be passed
It is handed to resistance assigning unit RA and assigns resistance to rope CD.In addition, in this case, inner cylinder 830A is had even if outer cylinder 830B rotates
Standby guiding axis 850 is also abutted with the long hole 824 of mobile shell 820, since mobile shell 820 is in the longitudinal direction by shell
810A limitation, therefore inner cylinder 830A becomes to rotate counterclockwise.
On the other hand, when the CD that restricts is mobile towards front (left of Figure 38), as shown in (b) of Figure 38, the outer of roller 830 is grabbed
Cylinder 830B rotates toward the clockwise direction (arrow Y-direction).At this point, due to there is sliding resistance between outer cylinder 830B and inner cylinder 830A
Power, therefore outer cylinder 830B and inner cylinder 830A starts to be rotated integrally.Then, while inner cylinder 830A rotates, inner cylinder 830A
The guiding axis 850 being had is towards the upper surface of the long hole 824 for being rotated clockwise, and pushing mobile shell 820, to will move
Dynamic shell 820 be pushed into top (referring to (b) of Figure 38, (b) of Figure 39, Figure 40 (b)).As a result, being maintained at mobile shell
The direction of roller 840 upward, i.e. close to rope CD of grabbing on body 820 is moved, and clamps rope CD with 830 co-operating of roller is grabbed.
When rope CD is mobile further towards front (left of Figure 38) in this case, the mobile of the CD that restricts is used as outer cylinder
The rotation of 830B and transmit.But after grabbing roller 840 and being abutted with rope CD, since mobile shell 820 cannot be moved towards more top again
It is dynamic, therefore inner cylinder 830A also becomes the state that can not be rotated again, thus only have outer cylinder 830B rotating relative to inner cylinder 830A.
It is above as a result, when in Figure 38 (b) grab roller 830 and grab in the state that roller 840 holds rope CD and make the CD that restricts
When mobile towards front (left of Figure 38), the movement for the CD that restricts sufficiently is transmitted as the rotation of outer cylinder 830B, resistance assigning unit
RA assigns brake force to the rotation of outer cylinder 830B, so that the CD that restricts is braked.
It is more than to grab roller 830 or grab the clamping under the original state of roller 840 also by limiting groove in this way, in this variation
Position and extend, also can be suitably thus even if in the case where grabbing roller 830 or grab the diameter of roller 840 and become smaller because of abrasion
Clamping rope CD.
