As shown in figure 3, wireline reel 12 is rotated forward centered on pivot 12A, when the entirety of screen 13 leaves guide rail 21, The downside end edge of screen 13 is located at the upside of guide rail 21.From the state, wireline reel 12 is inverted centered on pivot 12A, screen When the downside end edge of curtain 13 declines, the outer edge 13E of screen 13 enters：Front side is induced between wall 22F and rear side induction wall 22B.

At this moment, for example, the centre relative to front side induction wall 22F and rear side induction wall 22B induces wall 22F closer to front side Position, enter fashionable from the outer edge 13E of the location screen 13, the outer edge 13E of screen 13 induces wall 22F to guide by front side, Induced positioned at front side in the middle of wall 22F and rear side induction wall 22B.Also, for example, induce wall 22F and rear side induction relative to front side Wall 22B position is induced in the middle of wall 22B closer to rear side, enters fashionable from the outer edge 13E of the location screen 13, outside screen 13 Edge 13E induces wall 22B to guide by rear side, similarly, and wall 22F and rear side induction wall 22B centre are induced positioned at front side.

As shown in figure 4, front side channel formation part 23F is fixed on front side guide wall 21F trailing flanks, and back side walkway shape Rear side guide wall 21B leading flanks are fixed on into part 23B.Front side channel formation part 23F (example of movable part) and after Wing passage formation part 23B (example of movable part), with respect to front side channel formation part 23F and back side walkway shape Vertical plane into the middle of part 23B, with the symmetrical shape of plane each other.Therefore, front side channel shape is illustrated in more detail below Into part 23F structure, and back side walkway forming portion part 23B front side channels form the explanation of the structure of part 23F repetitions, are saved Slightly.

Front side channel formation part 23F, with the supporting part 23M for being fixed on front side guide wall 21F；Supporting part 23M has： Almost entirely front side guide wall 21F lifts the rectangular cylindrical in direction to span.In addition, movable part and guide rail 21 can be integrally formed Structure.In addition, front side channel formation part 23F supporting part 23M and front side guide wall 21F are integrally formed, can be by front side Guide wall 21F part composition.In supporting part 23M, on the angle of the center side of screen 13, along the semicircle of lifting direction extension The anticreep bent plate 23S of tubular is outstanding.Anticreep bent plate 23S, with prominent from supporting part 23M to back side walkway forming portion part 23B Semi-cylindrical shaped, from the point of view of lifting direction, with to back side walkway forming portion part 23B it is prominents, almost span it is whole on front side of lead The half-circle-arc shape in direction is lifted to wall 21F.

For anticreep bent plate 23S, from the point of view of lifting direction, have in the outer edge portion side of the center side of screen 13 and screen 13 End.In anticreep bent plate 23S end, the end of the center side of screen 13 is connected to supporting part 23M, the end of the outer edge portion side of screen 13 Portion is free end.Anticreep bent plate 23S is pliability elastomer, and the coupling part with anticreep bent plate 23S and supporting part 23M is connection Portion C1 is constituted for fulcrum bending.

In front side channel formation part 23F anticreep bent plate 23S, the most position of rear side is formed near back side walkway Part 23B position is contact site K, and back side walkway is formed in part 23B anticreep bent plate 23S, most the position of front side, i.e., most lean on Nearby wing passage formation part 23F position is also contact site K.This 2 contact site K, relative to each other.2 contact site K are in winding On type screen left and right directions, compared with connecting portion C1, positioned at the outer edge portion side of screen 13.

For guide channel 21G, part 23F anticreep bent plate 23S, and back side walkway forming portion are formed by front side channel Space (i.e. gap) between part 23B anticreep bent plate 23S is constituted, and the gap between 2 contact site K is set as：In screen Below 13 thickness.Gap between 2 contact site K, is set as：Along and into guide channel 21G outer edge 13E lifting Allow mobile size in direction.2 contact site K are contacted with entering guide channel 21G outer edge 13E, and screen 13 is along liter When dropping direction lifting, 2 contact site K and screen 13 outer edge 13E sliding contacts.

As shown in Fig. 5 double dot dash line, front side channel formation part 23F and back side walkway formation part 23B possibility Position in, 2 contact site K allow that the position of outer edge 13E liftings is, is used as the guiding position of an example of the 1st position. On the other hand, such as Fig. 5 shown in solid, front side channel formation part 23F and back side walkway formation part 23B possible position In putting, 2 contact site K, from position displacement is oriented to the central side of screen 13, are the anti-dislocations of an example as the 2nd position Put.

When the outer edge 13E of screen 13 starts to depart from, the reaction force of the frictional force by offsetting screen 13, front side channel Part 23F is formed from position displacement is oriented to anticreep position.Now, front side channel formation part 23F anticreep bent plate 23S, with Connecting portion C1 is fulcrum, is bent into and protrudes from the center side of screen 13.It is logical towards rear side for the anticreep bent plate 23S bent Road formation part 23B and protrude from contact site K direction, elastic force is improved.In addition, back side walkway formation part 23B also from Position displacement is oriented to anticreep position.Now, back side walkway formation part 23B anticreep bent plate 23S, using connecting portion C1 as Fulcrum, is bent into and protrudes from the center side of screen 13.For the anticreep bent plate 23S bent, towards front side channel formation part 23F And protrude from contact site K direction, elastic force is improved.Front side channel formation part 23F and back side walkway formation part 23B, by respective elastic deformation, moves to position to guiding position and anticreep, that is, constitutes displacement.

(effect of convoluted screen)

Then, illustrate by the above-mentioned effect for constituting the convoluted screen constituted.As shown in Fig. 5 double dot dash line line, in screen The outer edge 13E of curtain 13 is entered in guide channel 21G state, and front side channel formation part 23F and back side walkway are formed Part 23B, respectively positioned at respective guiding position.In this condition, make the outer edge 13E of screen 13 to center side depart from it is outer Power Fa, if acting on screen 13, the outer edge 13E of screen 13 is slowly started shedding off from guide channel 21G.

At this moment, the outer edge 13E of screen 13, is moved to center side from the outer edge portion side of screen 13, such as front side channel shape Center side is moved into part 23F contact site K from the outer edge portion side of screen 13 like that, the reaction force acts opposite with frictional force In on front side channel formation part 23F anticreep bent plate 23S.In addition, if back side walkway formation part 23B contact site K is from screen 13 outer edge portion sides of curtain move to center side like that, and similarly, the reaction force acts opposite with frictional force are formed in back side walkway On part 23B anticreep bent plate 23S.

Also, it is bent into anticreep using connecting portion C1 as fulcrum positioned at the front side channel forming portion part 23F for being oriented to position Bent plate 23S protrudes from the center side of screen 13, while allowing contact site K to the center side displacement of screen 13.Thus, front side channel forming portion Part 23F anticreep bent plate 23S, forms part 23B towards back side walkway and protrudes from contact site K, improve elastic force.In addition, position In the back side walkway formation part 23B for being oriented to position using connecting portion C1 as fulcrum, it is bent into anticreep bent plate 23S and protrudes from screen 13 center sides of curtain, while allowing contact site K to the center side displacement of screen 13.Thus, front side channel formation part 23F anticreep bent plate 23S, forms part 23B towards back side walkway and protrudes from contact site K, improve elastic force.Thus, front side channel formation part 23F and back side walkway formation part 23B, follow from guide channel 21G come off in screen 13, from position is oriented to anticreep Position displacement, as the confining force to outer edge 13E, pressing force is than being oriented to the high of position.Also, 2 contacts relative to each other Portion K, for the outer edge 13E during disengaging, is pressed with the pressing force after raising, outer edge 13E is sandwiched.Thus, shield Curtain 13 departs from from guide rail 21 to be suppressed.

In addition, it is necessary to special instruction, due to being added on outer edge 13E pressing, outer edge 13E is by frictional force, screen Curtain 13 further by the tension force more than the frictional force, is moved to the front side channel formation part 23F and rear side of anticreep position Passage formation part 23B, allows to depart from situation as follows：Allow that screen 13 departs from from their gap.

According to the convoluted screen of above-mentioned 1st embodiment, the effect that can be exemplified below.

(1) gap between front side channel forming portion part 23F and back side walkway formation part 23B, the outer rim of screen 13 When portion 13E starts to depart from, front side channel formation part 23F and back side walkway form what part 23B was contacted with screen 13 respectively Meanwhile, follow screen 13 and deform.Also, front side channel formation part 23F and back side walkway formation part 23B respectively from Position is oriented to, to the anticreep position displacement improved to outer edge 13E pressing forces.Therefore, from front side channel forming portion part 23F with after Gap between wing passage formation part 23B, outer edge 13E whole is come off and then screen 13 is pressed down from the disengaging of guide rail 21 System.

(2) front side channel formation part 23F and back side walkway formation part 23B, follows screen 13 and produces elasticity Deformation, the elastic force produced by the elastic deformation improves the pressing force to outer edge 13E.Also, front side channel formation part The degree of degree and back side walkway formation the part 23B of 23F elastic deformation elastic deformation is bigger, i.e. outer edge 13E takes off From degree it is bigger, the pressing force for being added on outer edge 13E is bigger.At this moment, the external force Fa for acting on screen 13 is bigger, outer edge It is bigger that 13E departs from degree.Therefore, if if said structure, being suitable for the external force Fa pressing force worked to screen 13, Be added on the 13E of outer edge, the pressing force worked to screen 13 is excessive relative to external force Fa, or screen 13 is worked by The pressure situation too small relative to external force Fa is suppressed.

(3) both front side channel formation part 23F and back side walkway formation part 23B, are moved to guiding position and anti- Take off to position.Therefore, no matter it is during towards disengaging on front side of convoluted screen, also by external force Fa outer edge 13E It by external force Fa outer edge 13E is during the disengaging towards on rear side of convoluted screen, due to the pressing of same degree to be Power, the disengaging of screen 13 is suppressed.

(4) front side channel formation part 23F anticreep bent plate 23S has：It is located at screen relative to connecting portion C1 contact sites K The semi-cylindrical shaped of 13 outer edge portion sides of curtain.Back side walkway formation part 23B anticreep bent plate 23S is likewise, relative to connecting portion C1 Contact site K is located at the semi-cylindrical shaped of the outer edge portion side of screen 13.Therefore, from front side channel forming portion part 23F and back side walkway shape Gap between part 23B, even if outer edge 13E is overall departing from towards front side channel formation part 23F and back side walkway Formed between part 23B, when outer edge 13E is inserted into, the outer edge 13E of screen 13 is reached in front side channel along semicircular cylinder Form part 23F and back side walkway formation part 23B line of demarcation.Therefore, front side channel formation part 23F and back side walkway shape Into the outer edge 13E that screen 13 is easily inserted between part 23B.

The convoluted screen of above-mentioned 1st embodiment, can also be deformed as described below.

Movable part is not limited to both front side channel formation part 23F and back side walkway formation part 23B or preceding Any one of wing passage formation part 23F and wing passage formation part 23B.

For example, back side walkway formation part 23B has the relative of the fixation equivalent to the anticreep bent plate 23S surface configurations Face, the anticreep bent plate 23S having with back side walkway forming portion part 23B opposite faces having and front side channel formation part 23F, The outer edge 13E of screen 13 can also be jammed.Or front side channel formation part 23F has equivalent to the anticreep bent plate 23S tables The opposite face of the fixation of face shape, with front side channel forming portion part 23F opposite faces having and back side walkway formation part 23B The anticreep bent plate 23S having, the outer edge 13E of screen 13 can also be jammed.Even such structure, can also obtain according to The effect of above-mentioned (1) (2) (4).

Front side channel formation part 43F have the supporting part 43M for being fixed on front side guide wall 21F, supporting part 43M have across Almost front side guide wall 21F lifts the column in direction to degree really.In addition, movable part and guide rail 21 can be integrally formed knots Structure.Also, front side channel formation part 43F supporting part 43M, and front side guide wall 21F are integrally formed, can be led as front side To a wall 21F part.Supporting part 33M supports：In the shaft-like cam 43S of anti-dropout of circular shape from the point of view of lifting direction, Rotate it.The shaft-like cam 43S of anti-dropout has：In fan-shaped output base end part 44 from the point of view of lifting direction, and from defeated Go out the force section 46 for the rod that base end part 44 extends to the center side of screen 13.

As shown in figure 9, front side channel formation part 43F output base end part 44 is using central shaft C3 as center, from center Axle C3 is to back side walkway forming portion part 43B in the fan shape extended.Front side channel formation part 43F output base end part 44, Lift on direction, span almost whole front side guide wall 21F makes the fan shape continuous.Base end part 44 is exported with central shaft C3 to make Centered on can swing, supporting part 43M support output base end part 44.

The outer peripheral face for exporting base end part 44 is cam surface 45, and the cam surface 45 has concaveconvex shape, and the concaveconvex shape is：By Constituted arranging multiple juts along in the circumference centered on central shaft C3.Also, cam surface 45 is：Along with center The poor face of ladder that the ladder difference of the radial direction of circle C centered on axle C3 is circumferentially repeated and constituted.

For the cam diameter of distance between cam surface 45 and central shaft C3, in cam surface 45, positioned at the outer edge of screen 13 The position of side is big.The minimum value of cam diameter is to be oriented to diameter R, and cam surface 45 is located the position of the outer edge portion side of screen 13, that In cam diameter it is bigger.In addition, the shape that output base end part 44 has, is located the outer edge portion side of screen 13 in cam surface 45 Position, cam diameter is bigger, and cam surface 45 can be：The shape of outer edge 13E pressings can be pressed.Also, in output base In end 44, global shape or cam diameter of base end part 44 etc. are exported, is suitably changed meeting in the condition and range.Front side In passage formation part 43F cam surface 45, most rear side, i.e., the part near back side walkway formation part 43B is counterpart Divide T, centered on central shaft C3 during each rotation cam face 45, in cam surface 45, opposite segments T is subjected to displacement.

Front side channel formation part 43F force section 46 has：From output base end part 44 to the center side of screen 13, and screen The circular shape of 13 front side extension.Front side channel formation part 43F force section 46, on lifting direction, span almost before Side guide wall 21F entirety, makes the circular shape continuous.In addition, the shape that force section 46 has is：From output base end part 44 to screen Curtain 13 center sides extension, and to the direction intersected with the surface direction of screen 13 make screen 13 motion when, due to the force section of screen 13 46 shapes being pressed, it is also possible.Also, with regard to the radius of curvature size of force section 46, the size of angle of bend, screen 13 On left and right directions for the length of length, according to screen 13 in front side or the displacement of rear side, and outer rim during 13 displacement of screen The angle of portion 13E bendings, is set appropriately.For example, the radius of curvature of force section 46 is bigger, the angle of bend of force section 46 is small It is smaller, and on the left and right directions of screen 13, the length of force section 46 is longer, and anti-anti-avulsion is carried out by the thin tail sheep of screen 13 From.On the contrary, the radius of curvature of force section 46 is smaller, the angle of bend in force section 46 is bigger, and in the right and left of screen 13 Upwards, the length of force section 46 is shorter, and progress prevents from departing from, and it is necessary that screen 13, which carries out big displacement,.Such force section 46 Followed with output base end part 44, output base end part 44 is fixed in force section 46.

Front side channel formation part 43F possible position, i.e., in the shaft-like cam 43S of anti-dropout possible position, anti-dropout Shaft-like cam 43S cam surface 45 is the position of outermost edge side, is the guiding position of an example as the 1st position.Before When wing passage formation part 43F is located at guiding position, the distance between opposite segments T and central shaft C3 are the minimums of cam diameter The guiding diameter R of value.Relative in this, front side channel formation part 43F possible position, i.e. the shaft-like cam 43S's of anti-dropout can In energy position, the shaft-like cam 43S of anti-dropout cam surface 45 is indexed to the center side position of screen 13 from guiding position, is conduct The anticreep position of one example of the 2nd position.When front side channel formation part 43F is located at anticreep position, opposite segments T and center The distance between axle C3 is bigger than being oriented to diameter R.

In addition, for supporting part 43M, pass through supporting for the supporting part 43M shaft-like cam 43S of limiting unit 43D and anti-dropout Connect, the cam surface 45 of restricted guidance position is moved to outer edge portion side at this.Guide channel 21G, part is formed by front side channel Space between the 43F shaft-like cam 43S of anti-dropout, and the back side walkway formation part 43B shaft-like cam 43S of anti-dropout is (i.e. Gap) constituted.When the shaft-like cam 43S of 2 anti-dropouts is located at guiding position, the gap between the shaft-like cam 43S of 2 anti-dropouts It is set to：Allow mobile size along and into guide channel 21G outer edge 13E lifting direction.2 anti-dropout bars When shape cam 43S is located at anticreep position, the gap between the shaft-like cam 43S of 2 anti-dropouts, its size is set as：Pass through cam Face 45 presses the size for the outer edge 13E for entering guide channel 21G.

(effect of convoluted screen)

Next, explanation：By the above-mentioned effect for constituting the convoluted screen constituted.

As shown in Figure 10, the outer edge 13E of screen 13 is in the state for entering guide channel 21G, front side channel forming portion Part 43F and back side walkway formation part 43B, positioned at respective guiding position.In this condition, towards the face side with screen 13 To the external force in the direction of intersection, for example, making the central portion of screen 13 protrude the external force Fa of the front side of screen 13, screen 13 is acted on Words, the outer edge 13E of screen 13 is slowly started shedding off from guide channel 21G.

At this moment, the outer edge 13E of screen 13, if moving to the front side of screen 13, is used as the contact of the part of force section 46 The outer edge 13E contacts of portion K and screen 13.From the state, the outer edge 13E of screen 13 moves further into the front side of screen 13 Words, contact site K is pressed against on screen 13, the front end of front side channel formation part 43F force section 46, in order to along Figure 10 arrows The front side of head direction screen 13 is moved, and force section 46 is rotated.If force section 46 is rotated centered on central shaft C3, base end part is exported 44 are also rotated centered on central shaft C3.

As shown in figure 11, if the rotation of base end part 44 is exported centered on central shaft C3, the cam surface of base end part 44 is exported 45, the position represented from Figure 11 double dot dash line line is moved to the position that Figure 11 solid lines are represented.Thus, in order that opposite segments T Become big with central shaft C3 distance, in the cam surface 45 of output base end part 44, opposite segments T position is subjected to displacement.Thus, Front side channel formation part 43F, and back side walkway formation part 43B, follow from guide channel 21G come off in screen 13, from position displacement is oriented to anticreep position, the pressing force for outer edge 13E is bigger than guiding position.Also, relative to each other 2 opposite segments T, the outer edge 13E during being departed from the pressing of the pressing force of increase, clamp outer edge 13E.Thus, Screen 13 is suppressed from the disengaging of guide rail 21.

In addition, the pressing by being added on outer edge 13E, outer edge 13E by frictional force, screen 13 further by more than During the tension force of the frictional force, the front side channel formation part 43F of anticreep position, and back side walkway formation part 43B are moved to Allow that screen 13 departs from from the gap between them.

According to the convoluted screen of above-mentioned 3rd embodiment, in addition to the effect of above-mentioned (1)~according to (6), also have with Under the effect enumerated.
