EP 2333229 A2 discloses a screen device in which the first guide is formed by connection of a plurality of the first guide units and each of the first guide units is provided with a pair of side walls arranged opposite to each other in the Y-axis direction when the first guide is brought out of the inner space of the slidable frame. In the first guide, among two adjacent first guide units, one first guide unit is pivoted on the other first guide unit. The first guide maintains linearity in the X-axis direction and is also bendable in the Z-axis direction by pivoting so that one end in the Z-axis direction of the expanded screen is inserted between the opposing side walls of the each of the first guide units at the brought-out portion of the first guide from the slidable frame. - Further, in the above-identified screen device, a pair of pins protrude outwardly from the opposing side walls at one end part in the X-axis direction of a part of the side walls of each of the first slide guide units. Said one end part extends in the X-axis direction of the side walls. A pair of openings are formed at the other end part in the X-axis direction of the side walls of each of the slide guide units. The adjacent two first guide units are connected by loosely fitting each of the pins of one first guide unit to a corresponding opening of the other first guide unit and the pins forms pivots.
- Furthermore, a pair of rigid protrusions directing an inner side between the opposing side walls of the first guide units are arranged at the same side parts of the side walls of the first guide units. The rigid protrusions extend along a virtual line in a plane including the virtual line virtually connecting centers of the pivots of the first guide units. The rigid protrusions stick one end part in the Z-axis direction of the screen inserted between side walls of each of the first guide units at the brought-out portions of the first guide when the first guide is brought out in the other side of the X-axis direction according to a sliding movement of the slidable frame in one side of the X-axis direction. Thus, the rigid protrusions hold one end part in the Z-axis direction of the screen so as not to slip out of the brought-out portions of the first guide when external forces such as a wind pressure are applied to the screen.
- However, since each of the guide units is generally an integral molded resin article, and sticking and slip-out of the protrusions is repeated by expansion and storage of the screen, there is a problem that the rigid protrusions are liable to transform by bending and partial breakages. Additionally, the screen is made of several materials under consideration of usage of installation location of the screen device. Accordingly, in the case where strength of a molding material of each of the first guide units is higher than that of the screen, one end part of the Z-axis direction of the screen is probably damaged. In order to suppress such a damage of the screen, it is necessary for the screen device above-identified to prepare a plurality of the first guide units by selecting a material correspond to a material of the screen from a plurality of materials. As a result, the plural first guide units made of different materials are necessary and it is not possible to make the slide guide in only one kind of material.
- In the light of the problems above-mentioned, the invention provides a screen device which suppresses breakages of one end part of the Z-axis direction of the screen which is inserted between the opposing side walls of the first guide even by repetition of expansion and storage of the screen and is able to be assembled with the first slide guide formed by only one kind of first slide guide units.

rail parts 63g functions as a guide when ascreen retaining member 9 is attached to and detached from thefirst guide 6. Referring toFig. 5(a) and Fig. 5(b) , thescreen retaining member 9 consists of abase part 91 which is bendable in a pivotally moving direction of thefirst guide units 63 of thefirst guide 6 and is longitudinal, and a plurality of needle-like parts 92 attached to the base 91 in intervals. Thescreen retaining member 9 is attached to the inner-side of each of theside walls base part 91 into the receivingparts 63i of thefirst guide units 63 from one of the left-side and right-side ends of thefirst guide 6. Therail parts 63g guide the insertion of thebase part 91 into the receivingparts 63i during attachment thescreen retaining member 9 to thefirst guide 6. In an attached condition of thescreen retaining member 9, thebase part 91 is supported between therail parts 63g and the supportingpieces 63h and all of the needle-like parts 92 inwardly protrude between the opposingside walls first guide units 63. Additionally, thescreen retaining member 9 is detached from thefirst guide 6 along therail parts 63g by bringing thebase part 91 out of an inner space of each of the receivingparts 63i of thefirst guide units 63 from one of the left-side and right-side ends of thefirst guide 6. - Specifically, the
base part 91 is locked by the lockingparts 63h1 of the supportingpieces 63h of thefirst guide units 63 and all of the needle-like parts 92 are slanted toward thebottom wall 63b along the declivity of theslant parts 63h2. SeeFig. 3(b) . A clearance in the Y-axis direction which is shown inFig. 2 is formed between tip ends of the needle-like parts 92 in a protrusion direction of twoscreen retaining members 9 attached to the opposingside walls - As mentioned above, since the
base part 91 of thescreen retaining member 9 is bendable in the pivotally moving direction of each of thefirst guide units 63 of thefirst guide 6, when thescreen retaining member 91 bends so as to direct toward the upper-side end of thefirst frame 2 shown inFig. 1 , as shown inFig. 6 , thescreen retaining member 9 bends in the same direction as one of thefirst frame 2. Further, since each of therail part 63g extends along the virtual line VL in the plane including the virtual line VL connecting the centers of the pivots of each of thefirst guide units 63, as shown inFig. 3(a) , the basedparts 91 of thescreen retaining members 9 is arranged parallel to the virtual line VL above-mentioned. The pivotal movements of the firstslide guide units 63, in other word, bending of thefirst guide 6, is smoothly achieved by such an arrangement as above-mentioned. Additionally, since the above-identified pivots are positioned at the upper-side end part of each of thefirst guide units 63, the pivots are upwardly positioned apart from a lower-side end of the opening in which the screen device SD is installed. Consequently, any of the pivots is hard to be influenced by dusts, sands and muds collected near the lower-side end of the opening above-identified and the closing operation of thefirst frame 2 by the user becomes swinging and stable together with the smooth bending of thefirst guide 6. Similarly, since thebase parts 91 of thescreen retaining members 9 in the bended condition are easily put back into an original condition, putting back of thefirst guide 6 into an original place when thefirst guide 6 is brought out of thefirst frame 2 is also smoothly attained. Consequently, the opening operation of thefirst frame 2 is also swinging and stable. - Furthermore, each of the opposing
side walls first guide unit 63 is provided with aconcavity 63j inwardly detented. Theconcavity 63j extends in the same direction as in one theportion 62 of thefirst guide 6 which is brought out of thefirst frame 2 and theconcavity 63j extends in the right-and-left side direction. A third recessedpart 63a4, similar to the first and second recededparts side walls side walls part 63a4 is arranged between the first recessedpart 63a1 and the second recessedpart 63a3. A second notch 63as is formed by being notched the inner-side faces between right-side end parts of the opposingside walls Fig. 4(b) and Fig 4(c) . - The second notch 63as of the
first guide unit 63 pivotably moving overlaps the third recessedpart 63a4 of thefirst guide unit 63 having finished pivotably moving of the adjacentfirst guide unit 63 when thefirst guide 6 is brought out of thefirst frame 2 and each of thefirst guide units 63 pivotably moved. Linearity of the brought-outportion 62 of thefirst guide 6 from thefirst frame 2 is maintained by such overlaps as above-mentioned and coming the right-and-lower side end part of theside walls first guide unit 63 pivotably moving into contact with the left-side end of theside walls first guide unit 63 having finished pivotable moving. The inner-side faces of theside walls concavities 63j are formed becomes flushness. - As shown in
Fig. 3(b) ,Fig. 4(c) and Fig. 4(d) , athird notch 63a6 is formed by cutting off each of the inner-side faces of a lower-side end part of each of the opposing second recessedparts 63a3. A cut-off depth of each of the third recessedparts 63a6 is shallow from the left-side end to the right-side end of each of the opposing second recessedparts 63a3. A guidedpiece 63k inwardly protruding between the opposingside walls pieces 63k is positioned at a lower-and right-side end of thebottom wall 63b. The guidedpieces lower rail 5 shown inFig. 1 , respectively, when thefirst guide 6 is brought out of thefirst frame 2. Such an engagement as above-mentioned suppresses separation of each of thefirst guide units 63 at the brought-outportion 62 of thefirst guide 6. On the other hand, each of thethird notches 63a6 smoothly releases the engagement of the each of the guidedpieces 63k with one side end part and the other side end part in the Y-axis direction of thelower rail 5 so that separation of each of theguide unit 63 from thelower rail 5 is easy. As a result, the sliding movement of thefirst frame 2 in the right-and-left direction is smoothly attained. - Coming back to
Fig. 1 , thefirst guide unit 63 positioned at the right-side end of thefirst guide 6 is fixed to the lower-side end part of thesecond frame 3 and the right-side end of thefirst guide 6 is a fixed end. Thefree end 61 of thefirst guide 6 is always stored in thefirst frame 2. Specifically, thefree end 61 is positioned at an upper-side end of anadjustor 10 going up-and-down along the longitudinal direction of thefist frame 2. Theadjustor 10 is connected with thefirst guide unit 63 positioned at the upper end when thefirst guide 6 is stored in thefirst frame 2. Aweight 101 which is longitudinal in the perpendicular direction and has a rod-shape is built in theadjustor 101. A gravity acting theweight 101 acts a stored portion of thefirst guide 6 in thefirst frame 2. When thefirst frame 2 is slid in the left-side direction, the gravity assists smooth brought-out of thefirst guide 6 from thefirst frame 2 in the right-side direction against the elastic force of thecoil spring 31a built in theroller pipe 31 and gives the closing operation of the user comfortable touch and stableness. Further, the gravity acting theweight 101 gives an appropriate resistance to storage of thefirst guide 6 in thefirst frame 2 and suppresses a rapid winding of thescreen 1 around peripheral surface ofroller pipe 31 by releasing the accumulated elastic force in thecoil spring 31a. -
Curved projections 11 are provided with a pair of inner-side faces, omitted inFig. 2 , opposite to each other in the Y-axis direction at the lower-side end part of thefirst frame 2. Each of thecurved projection 11 guides storage and brought-out of thefirst guide 6 in thefirst frame 2 by being inserted into theconcavities 63j of each of thefirst guide units 63. Thecurved projection 11 is curved at a prescribed curvature to bend thefirst guide 6 to smoothly direct upward in thefirst frame 2 and to put thefirst guide 6 back into the right-side direction. Accordingly, smoother storage and brought-out of thefirst guide 6 in and from thefirst frame 2 is attained. - In the above- mentioned screen device SD, when the
first guide 6 is brought out of the lower-side end part of thefirst frame 2 according to the sliding movement of thefirst frame 2 in the left-side direction, the lower-side end part of thescreen 1 is inserted between the opposingside walls first guide units 63 at the brought-outportion 62 of thefirst guide 6. Specifically, the lower-side end part of thescreen 1 is inserted into the above-identified clearance between tips in the protruding direction of the needle-like parts 92, shown inFig. 2 andFig. 3(a) and Fig. 3(b) , attached to each of the opposingside walls first guide units 63. At this time, each of the needle-like parts 92 of thescreen retaining member 9 sticks a part of thescreen 1 inserted into the above-identified clearance. It is disable for thescreen 1 to slip out of the brought-outportion 62 of thefirst guide 6. On the other hand, the needle-like pars 92 of thescreen retaining member 9 slip out of the part of thescreen 1 the needle-like parts 92 sticked when thefirst slide guide 6 is stored in thefirst frame 2 by the sliding movement in the right-side direction of thefirst frame 2. As mentioned above, in the screen device SD, since each of thescreen retaining member 9 is detachably attached to the inner-side part of each of the opposingside walls first guide units 63 of thefirst guide 6, a plural kind of thescreen retaining member 9 are prepared by mounting a plurality of the needle-like parts 92 of which a material corresponds to one of thescreen 1 on thebase part 91 in advance. It is possible to select an appropriatescreen retaining member 9 among the ones prepared in advance and to attach an appropriatescreen retaining member 9 to each of the opposingside walls first guide units 63 of thefirst guide 6. Accordingly, breakages at the lower-side end part of thescreen 1 are suppressed even by repletion of expansion and storage of thescreen 1. Additionally, it is unnecessary to make a plural kind of thefirst guide units 63 corresponding to the material of thescreen 1. Theslide guide 6 is formed by only one kind of thefirst guide unit 63. - An integrally molded article made of a rigid resin is able to be applied to the
first guide unit 63. A fabric knitted by resin fibers or a net is able to be applied to thescreen 1 under consideration of lightweight. A soft resin or a lightweight metal such as aluminum is applicable to thebase part 91 of thescreen remaining member 9. The needle-like parts 92 is made of an appropriate material corresponding to a material of thescreen 1. A size and an interval between a plurality of the needle-like parts 92 are determined for every kind ofscreen 1. For example, in the case of thescreen 1 is a knit or net, the size of the needle-like parts 92 is one which comes in stitches or networks, and the interval is as long as one between stitches or networks and is an even interval. Further, thecurve project 11 is made of a material which is hard to wear thefirst guide units 63 even by repetition of insertion of thecurved projection 11 into theconcavity 63j. - Furthermore, the
second guide 7 of the screen device SD is applicable to a conventional one. Similar to thefirst guide 6, the conventional guide is formed by connection of a plurality ofsecond guide units 73. Referring toFig. 7 , each of thesecond guide units 73 is provided with a pair ofside walls 73a, which are arranged opposite to each other in the Y-axis direction when thesecond guide 7 is brought out of thefirst frame 2, and abottom wall 73b connecting theside walls second guide 7, among two adjacent of thesecond guide units 73, onesecond guide unit 73 is pivoted on the othersecond guide unit 73. An upper-side part of the expandedscreen 1 is inserted between the opposingside walls second guide units 73 at a brought-outportion 72 of thesecond guide 7 from thefirst frame 2. Similar to thefirst guide 6, a right-side end of thesecond guide 7 is fixed to thesecond frame 3 and is a fixed end. - In the screen device SD, the first and
second guides first frame 2, respectively. A pair of dividingpieces 21 extending in a longitudinal direction of thefirst frame 2 and protruding in the inner space of thefirst frame 2 is provided on a pair of inner faces opposite to each other in the Y-axis direction of thefirst frame 2 except upper- and lower-side end parts of thefirst frame 2, respectively. The inner space of thefirst frame 2 is divided into afirst storage area 22 storing thefirst guide 6 and asecond storage area 23 storing thesecond guide 7 by the dividingpieces 21. Thefirst storage area 22 is positioned at a left-side of the inner space and thesecond storage area 23 at a right-side. Impinge of the first andsecond guides second storage areas second guides first frame 2 and therefore, lengths of the first andsecond guides like parts 92 of thescreen remaining members 9 attached to each of the opposingside walls first guide units 63 of thefirst guide 6 by thesecond guide 7 are prevented and there isn't any structural constraint for thesecond guide units 73 of thesecond guide 7. - Protruding tips of the dividing
pieces pieces member 12 connected with thesecond guide unit 73, which is positioned at the lower-side end when thesecond guide 7 is stored in thesecond storage area 23 and forms thefree end 71 of thesecond guide 2, as well as a guide for going up-and-down of theadjustor 10 of thefirst guide 6. Thefree end 71 of thesecond guide 7 is positioned at a lower end of the guidedmember 12. - Thus, since the first and
second guides 6 and7 are stored in the first andsecond storage areas first frame 2, respectively, a width size, i.e., a size in the right-and-left side direction, of thefirst frame 2 is comparatively wide. Under consideration of the width size of thefirst frame 2, it is desirable to apply thesecond guide unit 73 to a unit of which a size of the perpendicular direction of each of theside walls second guide unit 73 at a brought-outportion 72 from thesecond storage area 23 of thefirst frame 2 is shorter than that of each of theside walls first guide unit 63 at the brought-outportion 62 of thefirst guide 6 from thefirst frame 2. In the case where it is hard to attach a screen retaining member to each of the opposingside walls screen retaining member 9 attached to thefirst guide 6, ascreen retaining member 13 longitudinal in the right-and-left side direction is attached to a pair of each of the inner side faces opposite to each other in the Y-direction of theupper rail 4, as shownFig. 7 . A structure of thescreen retaining member 13 is similar one of thescreen remaining member 9. In this case, each of needle-like parts of thescreen remaining member 13 sticks the expandedscreen 1 and the slipping-out of the expandedscreen 1 from theupper frame 4 is suppressed even against external forces such as the wind pressure. Breakages of an upper-side end part of thescreen 1 is also suppressed even by repetition of the extraction and storage of thescreen 1. - Further, in the screen device SD, a bending
guide 14 bending with a prescribed curvature is arranged at an upper-side end part of thesecond storage area 23 of thefirst frame 2. Thebottom wall 73b of each of thesecond guide units 73 forming thesecond guide 7 comes into contact with a curved face of the bendingguide 14. The contact of thebottom wall 73b with thecurved face 141 pivotably moves each of thesecond guide units 73 so that thesecond guide 7 is bent and put into the right-and-left side direction, and storage and brought-out of thesecond guide 7 in and from thesecond storage area 23 according to the sliding movement of thefirst frame 2 in the right-and-left-direction is smoothly attained. The prescribed curvature is appropriately determined under consideration of such the bending and returning of thesecond guide 7. - Furthermore, in the screen device SD, a
direction changing member 15 such as a pulley are mounted on each of upper and lower end parts of thefirst storage area 22 of thefirst frame 2. Each of thedirection changing members 15 is preferably pivotally supported in a block forming the upper-and-lower side end parts of thefirst storage area 22. Thedirection changing member 15 changes a direction of thetension member 8 in the perpendicular direction and gives the tension member 8 a prescribed tension by hanging thetension member 8 on a part of a peripheral surface with a curved shape. - The
tension member 8 preferably forms an uncrossed loop. One end of thetension member 8 is fixed to thefree end 71 of thesecond guide 7 by a screw. Thetension member 8 directs upwardly and then changes a direction downwardly by being hanged on onedirection changing member 15 positioned at the upper-side end part of thefirst storage area 22. The tension member is fixed to thefree end 61 of thefirst guide 6. Further, thetension member 8 changes a direction upwardly by being hanged on the otherdirection changing member 15 positioned at the lower-side end of thefirst storage area 22 and the other end of thetension member 8 is fixed to thefree end 71 of thesecond guide 7 together with one end above-mentioned. Storage and brought-out lengths of the first andsecond guides first frame 2 are equal to each other by the loop-shapedtension member 8. As a result, thefirst frame 2 certainly slides parallel to thesecond frame 3 and the parallel skidding movement of thefirst frame 2 is achieved even though the closing operation is performed at an arbitrary part of thefirst frame 2 in the perpendicular direction. Similarly, the parallel siding movement of thefirst frame 2 is achieved at a time of the opening operation by the elastic force of thecoil spring 31a. - When one and the other ends of the
tension member 8 are fixed to thefree end 71 of thesecond guide 7, thetension member 8 enters thesecond storage area 23 from thefirst storage part 22. The entering of thetension member 8 is allowed since the protruding ends of the dividingpieces Fig. 7 . On the other hand, as above-mentioned, the width size of thefirst frame 2 is comparatively long and therefore there are some cases where a fitting operation of thetension member 8 to thefree end 71 is comparatively hard to be performed. In this case, a part of the guidedmember 12 forming thefree end 71 is protruded into thefirst storage area 22 and one and the other ends of thetension member 8 are fixed to a such a protruded part so that the fixing operation of thetension member 8 to thefree end 71 of thesecond guide 7 is facilitated. As shown inFig. 7 , anopening 24 communicating to thefirst storage area 22 is formed at a left-side end face of thefirst frame 2 and thetension member 8 is inserted into the inner space of thefirst frame 2 through theopening 24. The opening is preferably covered by a cover omitted inFig. 7 . - The invention is explained with respect to one embodiment as above-mentioned. However, the invention is not restricted to the embodiment. For example, except utilizing elastic force of the
coil spring 31a, automatically opening and closing realized by torque of a motor at a time of expansion and storage of thescreen 1 and manually opening and closing of the expansion and storage of thescreen 1 are applied to the screen device SD. A foldable screen with a plurality of pleats may be applicable to thescreen 1. Further, in the case where a screen device SD is manually opened and closed, thesecond frame 3 is not fixed to the opening above-identified, thesecond frame 3 in addition to thefirst frame 2 is slidable in the right-and-left aide direction. In this case, the screen device SD becomes a double opening screen device. Furthermore, the Z-axis direction is not limited to the vertical direction. The Z-axis direction may be at least an orthogonal direction against the X- and Y- axis directions. For example, it is possible to install the screen device SD within an opening inclined against a vertical plane.
