Fig. 5 is the engaging-in mechanism of a pawl type formula one-way clutch mechanism, comprising: the rotary component 30 that has recess 44 week; The on-rotatably moving part 8 that has recess 46 in periphery; Be contained in above-mentioned recess 44 and and above-mentioned recess 46 chimeric and overrunning clutch is in the lock state and the tine 48 of transmitting torque between rotary component 30 and on-rotatably moving part 8; And, to tine 48 to the spring 50 of on-rotatably moving part 8 reinforcings and constitute.In addition, also tine 48 and spring 50 can be configured in on-rotatably moving part 8 one sides, recess 46 is arranged on rotary component 30 1 sides.
The engaging-in mechanism of the pawl type of above structure formula one-way clutch mechanism is because if rotary component 30 rotates to a direction, then tine 48 is free to slide with respect to the periphery of on-rotatably moving part 8, so rotary component 30 and on-rotatably moving part 8 relatively dally.Secondly, if rotary component 30 will rotate to other direction, then tine 48 is chimeric with recess 46, and overrunning clutch is in the state that is lockable.
The square department of the output shaft 2 that is connected with the lowering or hoisting gear of window shade, screen or frame etc. combines to link each other in sense of rotation with the square hole of above-mentioned outlet side rotary component 4.In addition, above-mentioned housing 12 is fixed on body one side of above-mentioned lowering or hoisting gear, on input side rotary component 10 rotating operation unit is installed, and this rotating operation unit is made of with the rope form parts 18 that are wound on this pulley 10d pulley 10d.In the present embodiment, be in rotating force by the weight of window shade, screen or frame etc. the unidirectional state that is applied on the above-mentioned output shaft 2.
Below, the action of present embodiment is described.
If output shaft 2 is by will counterclockwise being rotated in Fig. 2 by the active force that weight produced of window shade or screen, frame etc., then the outlet side rotary component 4 that links with it is that the center will rotate to counter clockwise direction with the 10b of plate-like portion of input side rotary component 10, thereby engagement portion 4b pushes the 6b of fastening portion of relative helical spring 6a.Push by this, effect anticlockwise rotating force in Fig. 2 make helical spring 6a be in the state to rotary component 30 bandings, thereby helical spring 6a is locked on the rotary component 30 on the 6b of fastening portion.
At this lock state, anticlockwise rotating force from outlet side rotary component 4 is applied to rotary component 30, if rotary component 30 will be to rotation counterclockwise, needle roller 28 engaging-in outer circumferential faces then to on-rotatably moving part 8, thus rotary component 30 is locked on the on-rotatably moving part 8.Therefore, stoped the anticlockwise rotation in Fig. 2 of output shaft 2, thereby stoped the window shade of output shaft 2 or screen, frame etc. to fall because of weight.
Then explanation utilizes the rotary manipulation of input side to make output shaft 2 make the action of window shade or liftings such as screen, frame to the positive and negative direction rotation.
The occasion that rises making window shade or screen, frame etc. overcome its weight, operation rope form parts 18 grades make input side rotary component 10 clockwise direction rotation in Fig. 2.Make pulley 10d rotation if carry out the operation etc. of stay cord shape parts 18 by manpower etc., make input side rotary component 10 to the clockwise direction rotation, the then 6b of fastening portion of the engagement portion 10e of the 10b of plate-like portion of input side rotary component 10 and helical spring 6a collision.If clockwise rotating force acts on the 6b of fastening portion because of this collision, then helical spring 6a is in the state that banding becomes slack with respect to rotary component 30, and helical spring 6a is in the state that can rotate freely with respect to rotary component 30.
At this state, if apply clockwise rotating force from 10 couples of helical spring 6a of input side rotary component, then follow the rotation of input side rotary component 10 by the 6b of fastening portion, helical spring 6a will be with respect to rotary component 30 idle running.At this moment, the frictional force of the outer circumferential face by helical spring 6a and rotary component 30 and on rotary component 30, produce clockwise rotating force among the figure, therefore needle roller 28 with respect to on-rotatably moving part 8 to retreating in the opposite direction with engaging-in side, thereby rotary component 30 is in the state that can rotate freely with respect to on-rotatably moving part 8.
Rotating force cutting action by this engaging-in mechanism formula one-way clutch mechanism makes input side rotary component 10 not be subjected to the influence of the frictional force of helical spring 6a, and successfully rotates to clockwise direction with respect to on-rotatably moving part 8.Input side rotary component 10 clockwise direction when rotation in Fig. 2, the snap-latch piece 10c of input side rotary component 10, its engagement portion 10e contacts with the 6b of fastening portion of helical spring 6a, meanwhile, its side 10f is that the above-mentioned fastening 6b of portion is that engagement portion 4b contacts with the end face 4c of the surrounding wall portion 4a of outlet side rotary component 4.Like this, the clockwise rotation in Fig. 2 of input side rotary component 10 is delivered to outlet side rotary component 4, and output shaft 2 is to the clockwise direction rotation, thus window shade or risings such as screen, frame.The butt of end face 4c, the 4c of above-mentioned surrounding wall portion 4a and side 10f, the 10f of snap-latch piece 10c structure constitutes the rotation of input side rotary component 10 to engaging unit that outlet side rotary component 4 transmits.
In the occasion that window shade or screen, frame etc. are descended, operation rope form parts 18 grades make input side rotary component 10 rotation counterclockwise in Fig. 2.Make pulley 10d rotation if carry out the operation etc. of stay cord shape parts 18 by manpower etc., make input side rotary component 10 to rotation counterclockwise, the then 6b of fastening portion of the engagement portion 10e of the 10b of plate-like portion of input side rotary component 10 and helical spring 6a collision.If anticlockwise rotating force acts on the 6b of fastening portion because of this collision, then helical spring 6a is in the state that banding becomes slack with respect to rotary component 30, and helical spring 6a is in the state that can rotate freely with respect to rotary component 30.
At this state, if apply anticlockwise rotating force from 10 couples of helical spring 6a of input side rotary component, then follow the rotation of input side rotary component 10, relative rotary component 30 idle running of helical spring 6a by the 6b of fastening portion.At this moment, if because of the frictional force of the outer circumferential face of helical spring 6a and rotary component 30 produces anticlockwise rotating force among the figure on rotary component 30, then 28 pairs of on-rotatably moving parts 8 of needle roller are engaging-in, and rotary component 30 is in the state that is locked on the on-rotatably moving part 8.Therefore, while input side rotary component 10 is rotated to counter clockwise direction the influence of the caused frictional force of idle running of rotary component 30 by helical spring 6a.
The influence of the frictional force of this helical spring 6a is by being offset by the anticlockwise rotating force in Fig. 2 of caused output shaft 2 such as the weight of window shade or screen, frame etc.Therefore, input side rotary component 10 is successfully rotated.When input side rotary component 10 counterclockwise rotated in Fig. 2, snap-latch piece 10c contacted with the 6b of fastening portion of helical spring 6a, meanwhile, its side 10f by the 6b of fastening portion with the end face 4c butt of the surrounding wall portion 4a of outlet side rotary component 4.Like this, the anticlockwise rotation in Fig. 2 of input side rotary component 10 is delivered to outlet side rotary component 4, and output shaft 2 is to rotation counterclockwise, thus window shade or declines such as screen, frame.
Below, with reference to Fig. 6 and Fig. 7 other mode of execution of the present invention is described.
On housing 12, link the lifting body (omitting diagram) that frame etc. is arranged, this housing 12 because of the weight of this lifting body and deadweight by afterburning downwards.Housing 12 is supported on along the vertical direction lifting freely by the lifting guiding element on the body of lowering or hoisting gear of frame etc. (omitting diagram).On the body of above-mentioned lowering or hoisting gear, erect and be provided with tooth bar 52, be fixed on gear 54 and these tooth bar 52 engagements on the output shaft 2.Other structure is identical with first mode of execution, at the part of correspondence mark prosign and omit its explanation.
In above-mentioned structure, though because of the downward load that is applied on the housing 12 produces anticlockwise rotating force in Fig. 7 on output shaft 2, but output shaft 2 is by coil spring type clutch 6 and by on-rotatably moving part 8 one side locks, can be to rotation counterclockwise, housing 12 remains on state of rest usually.Make output shaft 2 positive and negative rotations and making housing 12 and the occasion of the lifting body lifting of the frame that links with it etc., pulley or the handle of operation setting on input side rotary component 10 by peripheral operation power is so that the 10 positive and negative rotations of input side rotary component.If make the 10 positive and negative rotations of input side rotary component, then outlet side rotary component 4 positive and negative rotations, output shaft 2 links and positive and negative rotation with it, thus housing 12 liftings.This action is identical with illustrated in the above-described first embodiment action, so omit its explanation.
In the above-described embodiment, though housing 12 has been made lifting structure freely, but also housing 12 can be made with first mode of execution and similarly be in stationary state, and tooth bar 52 is supported in lifting freely, and in this tooth bar 52 1 sides the lifting body of frame etc. is installed, the positive and reverse return by gear 54 then make the structure of tooth bar 52 liftings.
