Front side channel forming member 23F and back side walkway forming member 23B, marks off guide channel 21G between front side channel forming member 23F and back side walkway forming member 23B.On the guide channel 21G that front side channel forming member 23F and back side walkway forming member 23B divides, be with screen 13.

As shown in Figure 3, wireline reel 12 rotates forward centered by center of rotation 12A, and when screen 13 entirety leaves guide rail 21, limit, screen 13 lower side is positioned on the upside of guide rail 21.From this state, wireline reel 12 reverses centered by center of rotation 12A, and when limit, screen 13 lower side declines, the outer edge 13E of screen 13 enters: between front side induction wall 22F and rear side induction wall 22B.

At this moment, such as, induce the centre of wall 22B closer to the position of front side induction wall 22F relative to front side induction wall 22F and rear side, when entering from the outer edge 13E of this location screen 13, the outer edge 13E of screen 13 is guided by front side induction wall 22F, is positioned in the middle of front side induction wall 22F and rear side induction wall 22B.And, such as, relative to the position closer to rear side induction wall 22B in the middle of front side induction wall 22F and rear side induction wall 22B, when entering from the outer edge 13E of this location screen 13, the outer edge 13E of screen 13 is guided by rear side induction wall 22B, similarly, the centre of front side induction wall 22F and rear side induction wall 22B is positioned at.

As shown in Figure 4, front side channel forming member 23F is fixed on front side guide wall 21F trailing flank, and back side walkway forming member 23B is fixed on rear side guide wall 21B leading flank.Front side channel forming member 23F (example of movable part) and back side walkway forming member 23B (example of movable part), with respect to the vertical plane in the middle of front side channel forming member 23F and back side walkway forming member 23B, there is the shape of plane symmetry each other.Therefore, hereinafter explain the structure of front side channel forming member 23F, and the explanation of the structure of back side walkway forming member 23B front side channel forming member 23F repetition, be omitted.

Front side channel forming member 23F, has the support portion 23M being fixed on front side guide wall 21F; Support portion 23M has: span almost whole front side guide wall 21F is elevated the rectangular cylindrical in direction.In addition, movable part and guide rail 21 can be integrally formed structures.In addition, support portion 23M and the front side guide wall 21F of front side channel forming member 23F are integrally formed, can be made up of a part of front side guide wall 21F.In the 23M of support portion, on the angle of the center side of screen 13, the semicylindrical anticreep bent plate 23S extended along lifting direction is outstanding.Anticreep bent plate 23S, has from the support portion 23M semi-cylindrical shaped outstanding to back side walkway forming member 23B, from lifting direction, have to back side walkway forming member 23B outstanding, almost the whole front side guide wall 21F of span be elevated the half-circle-arc shape in direction.

With regard to anticreep bent plate 23S, from lifting direction, the outer edge portion side of screen 13 center side and screen 13 has end.In the end of anticreep bent plate 23S, the end of screen 13 center side is connected to support portion 23M, and the end of screen 13 outer edge portion side is free end.Anticreep bent plate 23S is flexibility elastic body, with the coupling part of anticreep bent plate 23S and support portion 23M and connecting portion C1 for fulcrum is bending and formed.

In the anticreep bent plate 23S of front side channel forming member 23F, the position of rear side, namely the position near back side walkway forming member 23B is contact site K, in the anticreep bent plate 23S of back side walkway forming member 23B, the position of front side, the position namely near front side channel forming member 23F is also contact site K.These 2 contact site K, relative to each other.2 contact site K, on convoluted screen left and right directions, compare with connecting portion C1, are positioned at screen 13 outer edge portion side.

With regard to guide channel 21G, by the anticreep bent plate 23S of front side channel forming member 23F, with the space (i.e. gap) between the anticreep bent plate 23S of back side walkway forming member 23B formed, the gap between 2 contact site K is set as: below screen 13 thickness.Gap between 2 contact site K, is set as: the size of movement is allowed in the lifting direction along the outer edge 13E entering guide channel 21G.2 contact site K contact with the outer edge 13E entering guide channel 21G, when screen 13 is along the lifting of lifting direction, and the outer edge 13E sliding-contact of 2 contact site K and screen 13.

As shown in the double dot dash line of Fig. 5, in the possible position of front side channel forming member 23F and back side walkway forming member 23B, 2 contact site K allow that the position of outer edge 13E lifting is, as the guiding position of an example of the 1st position.On the other hand, as shown in the solid line of Fig. 5, in the possible position of front side channel forming member 23F and back side walkway forming member 23B, 2 contact site K, from guiding position displacement to the central side of screen 13, are the anticreep positions of an example as the 2nd position.

When the outer edge 13E of screen 13 starts to depart from, by offsetting the reaction force of the frictional force of screen 13, front side channel forming member 23F is from guiding position displacement to anticreep position.Now, the anticreep bent plate 23S of front side channel forming member 23F, with this connecting portion C1 for fulcrum, is bent into and protrudes from screen 13 center side.With regard to bending anticreep bent plate 23S, protrude from the direction of contact site K towards back side walkway forming member 23B, elastic force improves.In addition, back side walkway forming member 23B is also from guiding position displacement to anticreep position.Now, the anticreep bent plate 23S of back side walkway forming member 23B, using this connecting portion C1 as fulcrum, is bent into and protrudes from screen 13 center side.With regard to bending anticreep bent plate 23S, protrude from the direction of contact site K towards front side channel forming member 23F, elastic force improves.Front side channel forming member 23F and back side walkway forming member 23B, by respective elastic deformation, moves to position to guiding position and anticreep, namely forms displacement.

(effect of convoluted screen)

Then, illustrate by the above-mentioned effect forming the convoluted screen formed.As shown in the double dot dash line line of Fig. 5, enter in the state of guide channel 21G at the outer edge 13E of screen 13, front side channel forming member 23F and back side walkway forming member 23B, lay respectively at respective guiding position.In this condition, the external force Fa that the outer edge 13E of screen 13 is departed to center side, acts on screen 13, the outer edge 13E of screen 13, from guide channel 21G slowly come off.

At this moment, the outer edge 13E of screen 13, the words of center side are moved from the outer edge portion side of screen 13, contact site K as front side channel forming member 23F moves to center side from screen 13 outer edge portion side, and the reaction force acts contrary with frictional force is on the anticreep bent plate 23S of front side channel forming member 23F.In addition, the contact site K as back side walkway forming member 23B moves to center side from screen 13 outer edge portion side, and similarly, the reaction force acts contrary with frictional force is on the anticreep bent plate 23S of back side walkway forming member 23B.

Further, the front side channel forming member 23F being positioned at guiding position, using this connecting portion C1 as fulcrum, is bent into anticreep bent plate 23S and protrudes from screen 13 center side, allow contact site K to the displacement of screen 13 center side simultaneously.Thus, the anticreep bent plate 23S of front side channel forming member 23F, protrudes from contact site K towards back side walkway forming member 23B, improves elastic force.In addition, the back side walkway forming member 23B being positioned at guiding position, using this connecting portion C1 as fulcrum, is bent into anticreep bent plate 23S and protrudes from screen 13 center side, allow contact site K to the displacement of screen 13 center side simultaneously.Thus, the anticreep bent plate 23S of front side channel forming member 23F, protrudes from contact site K towards back side walkway forming member 23B, improves elastic force.Thus, front side channel forming member 23F and back side walkway forming member 23B, follows the screen 13 from guide channel 21G comes off, and from guiding position to anticreep position displacement, as the confining force to outer edge 13E, pressing force is than the height of guiding position.Further, 2 contact site K relative to each other, for the outer edge 13E in detach procedure, press with the pressing force after improving, are sandwiched by this outer edge 13E.Thus, screen 13 departs from suppressed from guide rail 21.

In addition, it should be noted that, owing to being added on the pressing of outer edge 13E, outer edge 13E is subject to frictional force, screen 13 is subject to the tension force exceeding this frictional force further, be moved to front side channel forming member 23F and the back side walkway forming member 23B of anticreep position, allow that the following situation that departs from occurs: namely allow that screen 13 departs from from their gap.

According to the convoluted screen of above-mentioned 1st embodiment, the following effect enumerated can be obtained.

(1) from the gap between front side channel forming member 23F and back side walkway forming member 23B, when the outer edge 13E of screen 13 starts to depart from, while front side channel forming member 23F and back side walkway forming member 23B contacts with screen 13 respectively, follow screen 13 and be out of shape.Further, front side channel forming member 23F and back side walkway forming member 23B respectively from guiding position, to the anticreep position displacement improved outer edge 13E pressing force.Therefore, the gap between front side channel forming member 23F and back side walkway forming member 23B, outer edge 13E whole come off so that screen 13 suppressed from the disengaging of guide rail 21.

(2) front side channel forming member 23F and back side walkway forming member 23B, follows screen 13 and produces elastic deformation, and the elastic force produced by this elastic deformation improves the pressing force to outer edge 13E.Further, the degree of the degree of the elastic deformation of front side channel forming member 23F and the elastic deformation of back side walkway forming member 23B is larger, and namely the degree of outer edge 13E disengaging is larger, and the pressing force being added on outer edge 13E is larger.At this moment, the external force Fa acting on screen 13 is larger, and outer edge 13E disengaging degree is larger.Therefore, if said structure, be suitable for the pressing force to the external force Fa that screen 13 works, be added on the 13E of outer edge, the pressing force worked to screen 13 is excessive relative to external force Fa, or the pressing force worked to screen 13 situation too small relative to external force Fa is suppressed.

(3) both front side channel forming member 23F and back side walkway forming member 23B, be moved to guiding position and anticreep to position.Therefore, the outer edge 13E no matter being subject to external force Fa is in the process departed from front side of convoluted screen, still the outer edge 13E being subject to external force Fa is in the detach procedure on rear side of convoluted screen, and due to the pressing force of same degree, the disengaging of screen 13 is suppressed.

(4) the anticreep bent plate 23S of front side channel forming member 23F has: the semi-cylindrical shaped being positioned at screen 13 outer edge portion side relative to this contact site of connecting portion C1 K.The anticreep bent plate 23S of back side walkway forming member 23B is same, is positioned at the semi-cylindrical shaped of screen 13 outer edge portion side relative to this contact site of connecting portion C1 K.Therefore, gap between front side channel forming member 23F and back side walkway forming member 23B, even if outer edge 13E entirety has departed from, towards between front side channel forming member 23F and back side walkway forming member 23B, when outer edge 13E is inserted into, the outer edge 13E of screen 13, along semicircular cylinder, arrives the line of demarcation in front side channel forming member 23F and back side walkway forming member 23B.Therefore, the outer edge 13E of screen 13 is easily inserted between front side channel forming member 23F and back side walkway forming member 23B.

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

Movable part is not limited to front side channel forming member 23F and back side walkway forming member 23B, also can be front side channel forming member 23F and wing passage forming member 23B any one.

The cam surface of anticreep cam 33S can be multiple protuberance, or the male and fomale(M&F) that multiple recess arranges along cam surface.

(the 3rd embodiment)

Illustrate with reference to Fig. 8 ~ Figure 11: the sun screening device of the application is embodied as the convoluted screen of the 3rd embodiment of convoluted screen.The convoluted screen of the 3rd embodiment and the convoluted screen of the 1st embodiment, have the passage forming member be made up of different structure.Hereinafter, the structure that main explanation is different from the convoluted screen of the 1st embodiment, corresponding to the structure of the imparting same-sign of the convoluted screen construction of the 1st embodiment, no longer repeat specification.

(structure of convoluted screen)

As shown in Figure 8, form the front side channel forming member 43F of clamping part, be supported on the medial surface of front side guide wall 21F, and form the back side walkway forming member 43B of clamping part, be supported on the medial surface of rear side guide wall 21B.The back side walkway forming member 43B of the front side channel forming member 43F as an example of movable part and an example as movable part, with respect to the vertical plane in the middle of front side channel forming member 43F and back side walkway forming member 43B, there is the shape of plane symmetry each other.So, hereinafter explain the structure of front side channel forming member 43F, the no longer explanation of the structure repeated with front side channel forming member 43F in back side walkway forming member 43B.

Front side channel forming member 43F has the support portion 43M being fixed on front side guide wall 21F, support portion 43M have span almost really front side guide wall 21F be elevated the column in direction.In addition, movable part and guide rail 21 can be integrally formed structures.Further, the support portion 43M of front side channel forming member 43F, and front side guide wall 21F is integrally formed, can as a part of front side guide wall 21F.Support portion 33M supports: the shaft-like cam 43S of slip-off preventing from lifting direction being circular shape, makes it rotate.Slip-off preventing shaft-like cam 43S has: be fan-shaped output base end part 44 from lifting direction, and from the force section 46 of rod exporting base end part 44 and extend to screen 13 center side.

As shown in Figure 9, the output base end part 44 of front side channel forming member 43F, using central axis C3 as center, is the fan shape of expansion from central axis C3 to back side walkway forming member 43B.The output base end part 44 of front side channel forming member 43F, on lifting direction, span is whole front side guide wall 21F almost, makes this fan shape continuous.Export base end part 44 can swing using central axis C3 as center, support portion 43M supports and exports base end part 44.

Exporting the outer peripheral face of base end part 44 is cam surfaces 45, and this cam surface 45 has concaveconvex shape, this concaveconvex shape by: by being formed arranging multiple jut in the circumference centered by central axis C3.Further, cam surface 45 is: the ladder difference face that the ladder difference along the radial direction of the round C centered by central axis C3 circumferentially repeats and formed.

For the cam diameter of the spacing of cam surface 45 and central axis C3, in cam surface 45, the position being positioned at screen 13 outer edge portion side is large.The minimum value of cam diameter is guiding diameter R, and cam surface 45 is located the position of screen 13 outer edge portion side, and the cam diameter of there is larger.In addition, export the shape that base end part 44 has, in cam surface 45, be located screen 13 outer edge portion side position, cam diameter is larger, and cam surface 45 can be: can press the shape that outer edge 13E presses.Further, in output base end part 44, export the global shape of base end part 44 or cam diameter etc., suitably change meeting in described condition and range.In the cam surface 45 of front side channel forming member 43F, rear side, the part namely near back side walkway forming member 43B is opposite segments T, and centered by central axis C3 during each rotating cam face 45, in cam surface 45, opposite segments T is subjected to displacement.

The force section 46 of front side channel forming member 43F has: from output base end part 44 to screen 13 center side, and the circular shape that the front side of screen 13 extends.The force section 46 of front side channel forming member 43F, lifting direction on, span almost front side guide wall 21F entirety, make this circular shape continuous.In addition, the shape that force section 46 has is: extend from output base end part 44 to screen 13 center side, and when screen 13 being moved to the direction intersected with screen 13 surface direction, due to the shape that screen 13 force section 46 is pressed, is also fine.Further, with regard to the radius of curvature size of force section 46, the size of angle of bend, the length of length on screen 13 left and right directions, according to the displacement of screen 13 at front side or rear side, and the angle that during screen 13 displacement, outer edge 13E is bending, be set appropriately.Such as, the radius of curvature of force section 46 is larger, and the angle of bend of force section 46 is little, and on screen 13 left and right directions, the length of force section 46 is longer, is undertaken preventing from departing from by the thin tail sheep of screen 13.On the contrary, the radius of curvature of force section 46 is less, larger at the angle of bend of force section 46, and on the left and right directions of screen 13, force section 46 length is shorter, carries out preventing from departing from, and it is necessary that screen 13 carries out large displacement.Such force section 46 and output base end part 44 are followed, and force section 46 is fixed on and is exported base end part 44.

The possible position of front side channel forming member 43F, i.e., in the possible position of the shaft-like cam 43S of slip-off preventing, the cam surface 45 of the shaft-like cam 43S of slip-off preventing is the position of side, outermost edge, is the guiding position of an example as the 1st position.When front side channel forming member 43F is positioned at guiding position, the distance between opposite segments T and central axis C3 is the guiding diameter R of the minimum value of cam diameter.Relative in this, the possible position of front side channel forming member 43F, in the possible position of the i.e. shaft-like cam 43S of slip-off preventing, the cam surface 45 of the shaft-like cam 43S of slip-off preventing is indexed to the central side position of screen 13 from guiding position, be the anticreep position of an example as the 2nd position.When front side channel forming member 43F is positioned at anticreep position, the distance between opposite segments T and central axis C3 is all larger than guiding diameter R.

In addition, with regard to the 43M of support portion, by the limiting unit 43D of support portion 43M and the abutting of the shaft-like cam 43S of slip-off preventing, the cam surface 45 of restricted guidance position is moved to outer edge portion side from this.Guide channel 21G, by the shaft-like cam 43S of the slip-off preventing of front side channel forming member 43F, and the space (i.e. gap) between the shaft-like cam 43S of the slip-off preventing of back side walkway forming member 43B formed.When 2 shaft-like cam 43S of slip-off preventing are positioned at guiding position, the gap between 2 shaft-like cam 43S of slip-off preventing is set to: the size of movement is allowed in the lifting direction along the outer edge 13E entering guide channel 21G.When 2 shaft-like cam 43S of slip-off preventing are positioned at anticreep position, the gap between 2 shaft-like cam 43S of slip-off preventing, its size is set as: the size being entered the outer edge 13E of guide channel 21G by cam surface 45 pressing.

(effect of convoluted screen)

Next, illustrate: by the above-mentioned effect forming the convoluted screen formed.

As shown in Figure 10, the outer edge 13E of screen 13 is in the state entering guide channel 21G, and front side channel forming member 43F and back side walkway forming member 43B, is positioned at respective guiding position.In this condition, towards the external force in the direction that the direction, face with screen 13 intersects, such as, make screen 13 central portion give prominence to external force Fa on front side of screen 13, act on screen 13, the outer edge 13E of screen 13, from guide channel 21G slowly come off.

At this moment, the outer edge 13E of screen 13, moves on front side of screen 13, contacts with the outer edge 13E of screen 13 as the contact site K of force section 46 part.From this state, the outer edge 13E of screen 13 moves on front side of screen 13 further, and contact site K is pressed against on screen 13, the front end of the force section 46 of front side channel forming member 43F, in order to move on front side of Figure 10 direction of arrow screen 13, force section 46 is rotated.Force section 46 rotates centered by central axis C3, exports base end part 44 and also rotates centered by central axis C3.

As shown in figure 11, centered by central axis C3, export base end part 44 rotate, export the cam surface 45 of base end part 44, from the position that the double dot dash line line of Figure 11 represents, be moved to the position that Figure 11 solid line represents.Thus, in order to make the distance of opposite segments T and central axis C3 become greatly, in the cam surface 45 exporting base end part 44, the position of opposite segments T is subjected to displacement.Thus, front side channel forming member 43F, and back side walkway forming member 43B, follow the screen 13 from guide channel 21G comes off, and from guiding position displacement to anticreep position, the pressing force for outer edge 13E compares the large of guiding position.Further, 2 opposite segments T relative to each other, with the outer edge 13E in the pressing force increased pressing detach procedure, clamp this outer edge 13E.Thus, screen 13 is suppressed from the disengaging of guide rail 21.

In addition, by being added on the pressing of outer edge 13E, outer edge 13E is subject to frictional force, when screen 13 is subject to the tension force exceeding this frictional force further, be moved to the front side channel forming member 43F of anticreep position, and back side walkway forming member 43B allow screen 13 from them between gap depart from.

According to the convoluted screen of above-mentioned 3rd embodiment, except the effect of above-mentioned (1) ~ according to (6), also has the following effect enumerated.

(7) when being subjected to displacement to the direction screen 13 that the surface direction with screen 13 is intersected, the displacement of screen 13, compared with the outer edge 13E entering guide rail 21, the center side of screen 13 large.Therefore, be positioned at the force section 46 of screen 13 center side relative to cam surface 45, compare to cam surface 45 and easily check out such screen 13 displacement.Thus, to the direction motion screen 13 that the surface direction with screen 13 is intersected, pushing force section 46, cam surface 45 rotates thus, outstanding for screen 13, and the anticreep precision of screen 13 improves.

(8) because pressing outer edge 13E cam surface 45 be male and fomale(M&F), when cam surface 45 presses outer edge 13E, act on the pressing force of outer edge 13E, concentrate on multiple jut each in.Therefore under the prerequisite that the pressing force acted on the 13E of outer edge from cam surface 45 is equal, the unit area pressing force of outer edge 13E is large, gap between front side channel forming member 43F and back side walkway forming member 43B, the disengaging of outer edge 13E is suppressed further.

(9) the shaft-like cam 43S of the slip-off preventing of front side channel forming member 43F, this cam surface 45 is positioned at screen 13 outer edge portion side relative to force section 46.Similarly, this cam surface 45 is positioned at screen 13 outer edge portion side relative to force section 46 to the shaft-like cam 43S of slip-off preventing of back side walkway forming member 43B.Further, the force section 46 of front side channel forming member 43F has: from cam surface 45 to screen 13 center side, and the circular shape extended to the front side of screen 13.Further, the force section 46 of back side walkway forming member 43B, has: from cam surface 45 to screen 13 center side, and has the circular shape of prolongation to the rear side of screen 13.Therefore, gap between front side channel forming member 43F and back side walkway forming member 43B, even if outer edge 13E entirety has departed from, towards between front side channel forming member 43F and back side walkway forming member 43B, when outer edge 13E is inserted into, the outer edge 13E of screen 13, along cam surface 45, arrives the line of demarcation of front side channel forming member 43F and back side walkway forming member 43B.Therefore, the outer edge 13E of screen 13 is easily inserted between front side channel forming member 43F and back side walkway forming member 43B.

The convoluted screen of above-mentioned 3rd embodiment, also can as being hereafter out of shape.
