Description

  The present invention relates to a screen device that can be used as a curtain, a blind, a screen door, a partition, or the like, and a slide guide frame used in the screen device.

  The present applicant has so far proposed and provided a wide variety of screen devices that can be used as curtains, blinds, screen doors, partitions, and the like. One of them is a screen device described in Patent Document 1 below.

  This screen device is a so-called roll-up screen device in which a screen that opens and closes an opening such as a window is attached to a roller pipe so that the screen can be wound and pulled out.

  Specifically, the screen device described in Patent Document 1 has a screen that opens and closes in the horizontal direction and either one of the left and right ends of the screen, and is rotated by the elastic force of a built-in coil spring. It has a roller pipe that winds up. The screen device includes a screen mounting frame that is slidable in the opening and closing direction of the screen with respect to the roller pipe fixed at a predetermined position, and an upper slide guide frame provided in the vicinity of the upper and lower ends of the screen. And a lower slide guide frame.

  In the screen device, one end of the screen located on the opposite side of the one end attached to the roller pipe is attached to the screen attachment frame. Further, the upper slide guide frame is formed by rotatably connecting a plurality of first rigid units between two adjacent ones. Similarly, the lower slide guide frame includes a plurality of second rigid units. It is formed by being rotatably connected between two adjacent ones. The first rigid unit and the second rigid unit both have a pair of side wall portions and opposite side wall portions that are arranged to face each other and a bridging portion that connects the side wall portions to each other. Each of the upper slide guide frame and the lower slide guide frame has flexibility, and one end is a free end and can be stored and pulled out inside the screen mounting frame. In addition, the upper slide guide frame and the lower slide guide frame are both portions pulled out from the screen mounting frame when pulled out from the screen mounting frame portion as the screen mounting frame portion slides. Has a holding mechanism for maintaining linearity.

  In the screen device, the size of the first unit is smaller than the size of the second rigid unit. For this reason, when the upper slide guide frame and the lower slide guide frame are stored in the screen mounting frame, the side wall portion of the first rigid unit enters inside between the side wall portions of the second rigid unit. The upper slide guide frame intersects the lower slide guide frame inside the screen mounting frame.

  In the screen device described in Patent Document 1, in the state where the upper slide guide frame is housed inside the screen mounting frame, there can be a space between the screen mounting frame and the screen mounting frame. For this reason, a tool such as a screwdriver can be inserted into the screen mounting frame, and the connection between the second rigid units can be released by the inserted tool. Therefore, when the length of the screen device is shortened, the upper slide guide frame located on the cutting side can be taken out from the inside of the screen mounting frame, and the screen device can be adjusted by trimming the length dimension at a construction site or the like. To make it easier.

  On the other hand, in the screen device described in Patent Document 1, the upper and lower ends of the screen form the back surface of the side wall portion of the first rigid unit that forms the upper slide guide frame and the lower slide guide frame, respectively. The second rigid unit is disposed in proximity to the surface of the bridging portion. For this reason, when an external force due to wind or the like is applied in a direction intersecting the front and back surfaces of the screen, the screen bends so as to swell in a direction to receive the external force. Due to such bending of the screen, the lower end of the screen in particular rises from the surface of the bridging portion of the second rigid unit, and comparison is made between the lower end of the screen and the surface of the bridging portion of the rigid unit. Subsequent examination revealed that a large gap was formed. The gap formed as such can cause problems such as light leakage and insect invasion.

  Regarding the above problem, in the roller screen device described in Patent Document 2, a brush protruding inward from a guide element (corresponding to the second rigid unit) is attached to the bottom guide (corresponding to the lower slide guide frame) of the bottom guide. A brush is inserted into the mesh of the screen (corresponding to the screen) to prevent the screen from coming off from the bottom guide.

Japanese Patent No. 5284239 U.S. Pat. No. 7,810,543

  By the way, regarding the attachment of the brush, Patent Document 2 discloses a tip of an appendage 33 that is provided on a pair of opposing walls 31 in the main body 30 corresponding to the guide element and protrudes inside the main body 30 at the upper end of the wall 31. It is only illustrated to be attached to. In the case where the brush is provided over the entire length of the bottom guide 24, it is advantageous from the viewpoint of the convenience of installation that the brush is formed in a long shape and the long brush is inserted into the groove-shaped portion formed in the attachment 33. It is thought that.

  However, the long brush is generally formed by implanting a brush on a long base material. However, such a long brush is bent in the front and back direction of the base material. Although possible, it is difficult to bend in the direction intersecting the front and back direction of the substrate. Therefore, although the long brush can be inserted into the groove-shaped portion formed on the appendage 33, the bottom guide 24 cannot be bent after the long brush is inserted. As a result, the bottom guide 24 can no longer perform its intended function of storing and withdrawing the fixing element 10 inside. This is because, as described above, the appendage 33 is provided so as to protrude inward from the wall 31, and the groove-like portion extends in the length direction of the wall 31. It is because it becomes the direction which cross | intersects the front-and-back direction of the said base material in the said elongate brush inserted in the groove-shaped part.

  The present invention has been made in view of the circumstances as described above, and an external force acts in a direction crossing the front and back direction of the screen, and the bridge between the lower end of the screen and the rigid unit that forms the lower slide guide frame. Even if a gap is formed between the slide guide frame and the surface, the gap can be concealed by a long gap suppressor, and the flexibility is not impaired by the attachment of a long gap suppressor. It is an object of the present invention to provide a screen device using the above.

 In order to solve the above problems, a slide guide frame of the present invention includes a rigid unit having a pair of opposing side wall portions, a bridging portion that connects both side wall portions to each other, and a holding mechanism that maintains linearity.

  Further, in the slide guide frame of the present invention, the bridging portion is within a range from a longitudinal end of the side wall portion of the first portion to the through hole of the second portion, and the side wall. In the height direction of the part, one of the characteristics is that the side wall part is disposed at a height equal to the distance from one end located on the back side of the bridging part to the center of the rotation shaft.

  Further, the slide guide frame of the present invention is such that the clearance is within the range from the center of the rotation shaft to one end of the first portion on the second portion side on the surface side of the bridging portion. One feature is that a groove member for attaching the suppressor is provided as a pair at both ends in the width direction of the bridging portion.

  Further, the slide guide frame of the present invention, the gap suppression material comprises a long base material, and mohair planted on the base material and extending upright from the surface of the base material, One of the characteristics is that it is a member that can be bent in the front and back direction but has a rigidity that is difficult to bend in the direction crossing the front and back direction.

In the slide guide frame 1, a long gap suppressing material 6 is provided on the surface of the bridging portion 3 in the rigid unit 5 as a pair along the back surfaces 7 of the side wall portions 2 in the rigid unit 5.

  Specifically, as shown in FIG. 2A, in the rigid unit 5, the side wall portion 2 has an oval shape when viewed from the front. Moreover, as shown in FIGS. 2B and 2C, the bridging portion 3 is a thin plate having a rectangular shape.

  As shown in FIGS. 2A, 2B, and 2C, in the rigid unit 5, the side wall portion 2 has a rotating shaft 8 that protrudes outward from the surface of the rigid unit 5 and has a circular shape in front view. A first portion 9 and a second portion 11 penetrating the side wall 2 in the front and back direction, having a circular shape in front view, and having a through hole 10 having an inner diameter equal to the outer diameter of the rotating shaft 8; have. Specifically, the rotation shaft 8 is disposed at the center of the side wall 2 in the height direction of the first portion 9.

  The first portion 9 has a first cutout portion 12 whose surface portion is cut out by the thickness of the second portion 11, and the first cutout portion 12 is formed on the first boundary portion 13 with the second portion 11.

  The second portion 11 has a second notch portion 18 whose back portion is notched by the thickness of the first portion 9, and the second notch portion 18 is formed on the second boundary portion 19 with the first portion 9. The third arcuate part 20 has a curvature equal to the curvature of the first arcuate part 14. The center of the third arcuate portion 20 coincides with the center of the through hole 10. The second portion 11 has a fourth arc-shaped portion 22 having a curvature equal to the curvature of the third arc-shaped portion 20 at one end 21 located on the opposite side of the second boundary portion 19.

  Further, in the rigid unit 5, the bridging portion 3 is within the range from the front end in the length direction of the side wall portion 2 in the first portion 9 to the through hole 10 in the second portion 11 and the height of the side wall portion 2. In the vertical direction, the side wall portion 2 is disposed at a height equal to the distance from one end located on the back side of the bridging portion 3 to the center of the rotating shaft 8. In the bridging portion 3, the groove member 23 for attaching the gap suppressing member 6 is within the range from the center of the rotation shaft 8 to one end of the first portion 9 on the second portion 11 side. A pair is provided at both ends in the width direction.

  Specifically, the groove member 23 includes a first piece 24 protruding from the back surface of the first portion 9 located above the bridging portion 3 to the inside of the side wall portion 2, and a surface of a portion near the center of the bridging portion 3. And a second piece 25 having an L-shaped cross section that extends upright and bends toward the first piece 24 side. In the groove member 23, the tip of the first piece 24 and the tip of the portion bent toward the first piece 24 of the second piece 25 are spaced apart from each other by a certain distance and are opposed to each other. As a result, the groove member 23 forms a groove 26 having a C-shaped cross section that opens in the height direction of the side wall portion 2 with the surface of the bridging portion 3.

  The first piece 24 may have an L-shaped cross-section that extends upright from the surface of the bridging portion 3 and bends toward the second piece 25 in the same manner as the second piece 25. Absent.

  Specifically, the holding mechanism 4 is provided in the vicinity of the rotation shaft 8 in the first portion 9, has an arcuate shape in plan view, and extends from the surface of the first notch 12 to the tip surface 17 of the rotation shaft 8. And a long hole 28 that is provided in the vicinity of the through hole 10 in the second portion 11, has an arc shape in plan view, and penetrates the front and back of the second notch portion 11. And is formed from. The curvature of the long hole 28 is equal to the curvature of the protrusion 27.

  More specifically, the protrusion 27 is located near the one end 15 from the center of the rotation shaft 8 and is disposed in the vicinity of 45 ° with respect to the rotation shaft 8 on the upper side in the height direction of the side wall 2. ing. The long hole 28 is disposed adjacent to the through hole 10 on the first boundary portion 13 side of the second portion 11.

  The rigid unit 5 as described above can be formed of a hard plastic, a lightweight metal such as aluminum, and the like, and can be integrally formed.

  As shown in FIGS. 3A and 3B, the gap suppressing member 6 includes a long base material 29 and a mohair 30 that is planted on the base material 29 and extends upright from the surface of the base material 29. ing. The base material 29 is a member that can be bent in the front-back direction, but has rigidity that is difficult to bend in a direction intersecting the front-back direction. Specifically, the base material 29 can be a relatively thin member having a size within the width and depth of the groove 26 formed in the groove member 23, and can be formed from a resin such as polypropylene. There is no restriction | limiting in particular in the material of mohair 30, The appropriate raw material which can be easily attached to the base material 29 can be selected. The length of the mohair 30 is not particularly limited, but when the appearance of the screen device is taken into consideration, the length of the mohair 30 is the bridge portion 3 in the height direction of the side wall portion 2 from the surface of the bridge portion 3 of the rigid unit 5. It is preferable to set the length to reach one end on the surface side.

  As shown in FIG. 1, the slide guide frame 1 includes two rigid units 5 in which the rotation shaft 8 is inserted into the through hole 10 from the back surface side of the second portion 11 in two adjacent rigid units 5. 5 is formed such that one is rotatably connected to the other. Therefore, the slide guide frame 1 has flexibility due to the rotatable connection between two adjacent rigid units 5 and can be held linearly by the holding mechanism 4.

  Regarding the maintenance of the linearity, specifically, when the plurality of rigid units 5 are connected, in the two adjacent rigid units 5, the protrusions 27 shown in FIGS. The linearity of the slide guide frame 1 is maintained in a state in which the second portion 11 is inserted into the long hole 28 from the back surface side and one end of the protrusion 27 is in contact with one end of the long hole 28 located on the one end side. More specifically, the one end of the protrusion 27 is a portion located on one end side in the height direction of the side wall portion 2 of the rigid unit 5 and arranged at a position higher than the surface of the bridging portion 3. In addition, the one end of the long hole 28 is a portion located on the same side as the one end of the protrusion 27.

  When the holding mechanism 4 formed from such a protrusion 27 and the long hole 28 is adopted, the slide guide frame 1 is flexed so that the one end of the protrusion 27 is in contact with the one end of the long hole 28. This is realized within a range until the other end contacts the other end of the long hole 28.

  The holding mechanism 4 is not limited to the one formed from the protrusions 27 and the long holes 28. For example, although not shown, in the rigid unit 5, a third notch is formed on the back surface of one end of the bridging part 3 located on the one end 15 side of the side wall part 2, and the second part in the bridging part 3 It is also possible to form a fourth cutout portion on the surface portion of the other end near 11 and form the holding mechanism 4 from these third cutout portion and fourth cutout portion. In this case, in the two adjacent rigid units 5, when the third cutout portion of one rigid unit 5 is placed on the fourth cutout portion of the other rigid unit 5, the rotation of the rigid unit 5 is inhibited. Thus, the slide guide frame 1 can maintain linearity.

  As shown in FIG. 1, in the slide guide frame 1, the long gap suppressing member 6 is provided over the entire length of the slide guide frame 1 with the base material 29 inserted into the groove member 23. Specifically, the base material 29 is inserted into the groove 26 of the groove member 23 shown in FIGS. 2A, 2 </ b> B, and 2 </ b> C. It is attached to the guide frame 1.

  As shown in FIG. 4, the gap suppressing member 6 is provided as a pair at both ends in the width direction of the bridging portion 3 of the rigid unit 5, and is disposed along the back surfaces of the side wall portions 2 of the rigid unit 5. . The mohair 30 is arranged upright from the surface of the bridging portion 3. Specifically, the mohair 30 projects to the outside of the groove 26 from a portion that opens in the height direction of the side wall 2 of the rigid unit 5 in the groove member 23 shown in FIGS. To do.

  FIG. 5 is a main part side view showing a state in which an external force is applied to the screen in a direction intersecting the front and back direction in the screen device provided with the slide guide frame shown in FIG. 1 in the lower slide guide frame. .

  In the screen device provided with the slide guide frame 1 as described above in the lower slide guide frame, when an external force due to wind or the like is applied in a direction intersecting the front and back surfaces of the screen 31 as shown in FIG. It bends to swell in the direction of receiving external force. With such bending of the screen 31, the lower end of the screen 31 is lifted from the surface of the bridging portion 3 of the rigid unit 5, and is relatively large between the lower end of the screen 31 and the surface of the bridging portion 3 of the rigid unit 5. A gap 32 is formed.

  However, in the slide guide frame 1, since the long gap suppressing material 6 is provided as a pair along the back surfaces 7 of the side wall portions 2 in the rigid unit 5, it is disposed between the pair of gap suppressing materials 6. The gap 32 formed on the lower side of the screen 31 is hidden by the mohair 30. For this reason, the gap 32 is prevented from communicating with the outside on the front and back of the screen device, and problems such as light leakage and invasion of insects are solved. Depending on the raised state of the mohair 30 and the material of the screen 31, the tip of the mohair 30 may pierce the screen 31, but the mohair 30 is arranged upright from the surface of the bridging portion 3 of the rigid unit 5. Therefore, with the sliding movement of the screen mounting frame, the tip of the mohair 30 can be easily detached from the screen 31, and the risk that the lower end of the screen 31 is damaged by the mohair 30 can be kept low.

  6 is a partially cutaway front view showing the bendability of the slide guide frame shown in FIG. 1. FIG. 6A is a state in which the slide guide frame maintains linearity, and FIG. The guide frame is shown in a bent state.

  As described above, in the slide guide frame 1, the bridging portion 3 is within the range from the distal end in the length direction of the side wall portion 2 in the first portion 9 to the through hole 10 in the second portion 11, and the side wall portion. In the height direction 2, the side wall portion 2 is disposed at a height equal to the distance from one end located on the back side of the bridging portion 3 to the center of the rotation shaft 8. Further, the groove member 23 for attaching the gap suppressing member 6 is provided in the bridging portion 3 within a range from the center of the rotation shaft 8 to one end of the first portion 9 on the second portion 11 side. Yes. For this reason, as shown in FIGS. 6A and 6B, the interval L between the groove members 23 provided in the bridging portion 3 of the two adjacent rigid units 5 in the state where the slide guide frame 1 is bent is as follows. This is equal to the distance L between the groove members 23 in a state where the slide guide frame 1 maintains linearity.

  Moreover, the bending direction of the slide guide frame 1 coincides with the direction in which the base material 29 included in the gap suppressing member 6 can be bent. Therefore, even if the gap suppressing member 6 is a long member, it follows the bending of the slide guide frame 1, easily bends at an arbitrary portion, and inhibits the bending when the slide guide frame 1 is bent. Don't stretch like that. When the groove member 23 extends, for example, from the center of the rotation shaft 8 to the outside in the length direction of the side wall portion 2, as shown in FIG. 6B, the bridging portion 3 in the two adjacent rigid units 5. Since a step is generated between them, even if the base material 29 can be bent in the front and back directions, the gap suppressing member 6 is stretched unless the base material 29 extends in the length direction. As a result, the slide guide frame 1 is difficult to bend.

  In this way, as shown in FIG. 5, the slide guide frame 1 has an external force acting in a direction intersecting the front and back direction of the screen 31, and the rigid unit 5 that forms the lower end of the screen 31 and the lower slide guide frame. Even if the gap 32 is formed between the surface of the bridging portion 3, the gap 32 can be hidden by the long gap suppressing material 6. Moreover, the flexibility of the lower slide guide frame 1 is not impaired by the attachment of the long gap suppressing member 6.

  In addition, in the slide guide frame 1, the center of the first arcuate part 14 coincides with the center of the rotation shaft 8, the second arcuate part 16 has the same curvature as the first arcuate part 14, and the first arcuate part Since the center of the third arcuate portion 20 having a curvature equal to the curvature of 14 coincides with the center of the through hole, and the fourth arcuate portion 22 has the same curvature as the third arcuate portion 20, the slide guide frame 1 Bending is performed smoothly. Further, even if the slide guide frame 1 is bent, it is possible to suppress the portion of the first portion 9 located on the one end portion 15 side from being exposed.

  Further, in the first cutout portion 12, the rotation shaft 8 extends until the tip surface 17 is disposed on the same plane as the surface of the second portion 11, and the protrusion 27 rotates from the surface of the first cutout portion 12. Since it protrudes within a length range reaching the tip surface 17 of the shaft 8, the front and back surfaces of the slide guide frame 1 formed by connecting the plurality of rigid units 5 are substantially flush.

  FIG. 7 is a partially cutaway front view showing an embodiment of the screen device of the present invention in which the slide guide frame shown in FIG. 1 is a lower slide guide frame. In FIG. 7, members described with reference to FIGS. 1 to 5 are denoted by the same reference numerals, and description thereof is omitted below.

  The screen device 40 includes a screen 31 that opens and closes in the horizontal direction, and a roller pipe 42 that is attached to one of the left and right ends of the screen 31, rotates by the elastic force of a built-in coil spring 41, and winds the screen 31 around the outer periphery. ing. The screen device 40 is slidable in the opening and closing direction of the screen 31 with respect to the roller pipe 42 fixed at a predetermined position, and one end of the screen 31 located on the opposite side to the one end attached to the roller pipe 42 is A screen mounting frame 43 is provided, and an upper slide guide frame 44 and a lower slide guide frame 45 provided near the upper and lower ends of the screen 31, respectively.

  In the screen device 40, the upper slide guide frame 44 has a first rigidity having a pair of side wall portions 46 arranged opposite to each other, a bridging portion 47 that connects both side wall portions 46 to each other, and a holding mechanism (not shown) that maintains linearity. A plurality of units 48 are formed so as to be rotatable between two adjacent units. As the lower slide guide frame 45, the slide guide frame 1 shown in FIGS. The upper slide guide frame 44 is also flexible like the lower slide guide frame 45. One end of each of the upper slide guide frame 44 and the lower slide guide frame 45 is a free end 44a, 45a, and can be stored and pulled out inside the screen mounting frame 43. At the same time, when pulled out from the screen mounting frame 43, the portion pulled out from the screen mounting frame 43 maintains linearity by a holding mechanism such as the holding mechanism 4, for example.

  Further, in the screen device 40, the size of the first rigid unit 48 is made smaller than the size of the rigid unit 5 as the second rigid unit 49 that forms the lower slide guide frame 45. For this reason, when the upper slide guide frame 44 and the lower slide guide frame 45 are housed inside the screen mounting frame 43, the side wall portion 46 of the first rigid unit 48 enters the inside between the side wall portions 2 of the rigid unit 5. The upper slide guide frame 44 intersects with the lower slide guide frame portion 45 inside the screen mounting frame 43.

  Specifically, the screen 31 is formed from a fabric such as a woven fabric or a knitted fabric, and is appropriately selected depending on required characteristics such as a light-shielding property and a material that can be used as an insect net. Is.

  The roller pipe 42 includes a substantially cylindrical hollow main body 50 and a bearing 51 to which the main body 50 is connected at the lower end. A rotating shaft 52 is disposed inside the main body 50, and the rotating shaft 52 extends from the bearing 51 to the middle of the main body 50 in the height direction. The main body 50 includes a coil spring 41, and the coil spring 41 is provided on the outer periphery of the rotating shaft 52. The main body 50 is housed in a hollow case 53, and the case 53 is formed with a slit (not shown) that allows the screen 31 to enter and exit on the side surface in the opening / closing direction of the screen 31. Note that the other ends of the upper slide guide frame 44 and the lower slide guide frame 45 located on the side opposite to the free ends 44 a and 45 b are detachably attached to the case 53 and fixed.

  When the coil spring 41 is twisted, an elastic force is accumulated, and when the accumulated elastic force is released, the main body 50 automatically rotates about the rotation shaft 52. At this time, the screen 31 having one end attached to the roller pipe 42 is wound around the outer periphery of the main body 50 and opened. When the wound screen 31 is pulled out in the closing direction, the main body 50 of the roller pipe 42 rotates in the direction opposite to the direction in which the screen 31 is opened, the coil spring 41 is twisted, and the elastic force is accumulated.

  In the screen device 40, a long lower rail 54 is provided in the opening / closing direction of the screen 31 so that the sliding movement of the screen mounting frame 43 is smoothly realized. The lower rail 54 can be fixed to a floor surface, for example.

  As described above, the upper slide guide frame 44 has the same basic portion as the lower slide guide frame portion 45, but the holding mechanism provided in the first rigid unit 48 is a rigid unit as the second rigid unit 49. 5 is different from the holding mechanism 4 formed by the protrusion 27 and the long hole 28. Although not shown, the holding mechanism included in the first rigid unit 48 is provided immediately below one end portion of the bridging portion 47 located on the rotating shaft 8 side, and protrudes outward from the one end portion of the bridging portion 47. It is formed from a stepped part. The step portions are provided as a pair at both ends of the bridging portion 47 in the width direction.

  In such a holding mechanism, of the two adjacent first rigid units 48, the other end portion located on the through hole 10 side in the bridging portion 47 of one first rigid unit 48 is overlapped on the stepped portion. By doing so, the rotation of the first rigid unit 48 is stopped. For this reason, the upper slide guide frame 44 can maintain linearity.

  The upper slide guide frame 44 can be bent downward, and the lower slide guide frame 45 can be bent upward.

  Further, the upper slide guide frame 44 and the lower slide guide frame 45 are connected to each other at the free ends 44a and 45a by a tension member 55 appropriately selected from a wire such as a string or a wire. The upper slide guide frame 44 and the lower slide guide frame 45 are connected by a tension member 55 so that the amount of movement of the screen mounting frame 44 in and out of the screen mounting frame 43 due to the sliding movement of the screen mounting frame 43 becomes substantially equal. The translation relative to the pipe 42 is made more reliable. The tension member 55 forms a loop inside the screen mounting frame 44 and is folded back on both upper and lower sides of the screen mounting frame 43.

  Folding members 56 are provided at two upper and lower positions inside the screen mounting frame 43 where the tension member 55 is folded. The folding member 56 can be formed to include a pulley having a curved surface on the outer peripheral surface on which the tension member 55 can be wound.

  Further, in the screen mounting frame 43, concave guide surfaces 57 that guide the bending of the upper slide guide frame 44 and the lower slide guide frame 45 are provided at both upper and lower ends where the upper slide guide frame 44 and the lower slide guide frame 45 advance and retreat. A guide block 58 is provided on the inner side.

  Furthermore, since the lower slide guide frame 45 is housed inside from below the screen mounting frame 43 and the housing direction is opposite to gravity, a weight 59 is connected to the free end 45a side. The weight 59 causes its own weight to act on a portion of the lower slide guide frame 45 that rises from below, and when the lower slide guide frame 45 is pulled out from the screen mounting frame 43, the lower slide guide frame 45 is pushed out appropriately. Further, when the lower slide guide frame 45 is housed inside the screen mounting frame 43, entry of the lower slide guide frame 45 is moderately suppressed. For this reason, the storage and drawing of the lower slide guide frame 45 inside the screen mounting frame 43 is realized smoothly and stably.

  The upper slide frame 44 and the lower slide guide frame 45 as described above are accommodated in the screen mounting frame 43 and pulled out as the screen mounting frame 43 slides in the horizontal direction. The portion pulled out from the screen mounting frame 43 maintains linearity by the rigid unit 5 as the first rigid unit 48 and the second rigid unit 49.

  In the upper slide guide frame 44 and the lower slide guide frame 45, the size of the first rigid unit 48 is made smaller than the size of the second rigid unit 49. For this reason, in the screen device 40, when the upper slide guide frame 44 and the lower slide guide frame 45 are housed inside the screen mounting frame 43, the side wall portion 46 of the first rigid unit 44 serves as the second rigid unit 49. The upper slide guide frame 44 intersects with the lower slide guide frame 45 inside the screen mounting frame 43. Such an intersection makes it possible to apply the screen device 1 to an opening of a building having a large width to height ratio, and to flexibly cope with the size of the opening of the building.

  Further, since the lower slide guide frame 45 can be accommodated in the screen mounting frame 43, the upper slide guide frame 44 formed from the first rigid unit 48 smaller than the rigid unit 5 is attached to the screen. It is housed inside the screen mounting frame 43 with a space between it and the frame part 43. For this reason, a tool such as a screwdriver can be inserted into the screen mounting frame 43 to release the connection between the first rigid units 48.

  The screen device 40 needs to be adjusted in length according to the size of the opening of the building at a construction site or the like. In this case, the upper end portions of the screen mounting frame 43, the screen 31, the case 53, and the roller pipe 42 are cut. At this time, the upper slide guide frame 44 is disposed near the upper end of the screen 31. Then, the upper slide guide frame 44 becomes an obstacle to the length reduction work. In the screen device 40, the upper slide guide frame 44 is housed inside the screen mounting frame 43 with a space between the screen mounting frame 43 and the first rigid unit 48 when filling the length. The upper slide guide frame 44 can be taken out from the inside of the screen mounting frame 43 by releasing the connection therebetween. Further, the upper slide guide frame 44 can be removed from the case 53 when the length is reduced.

  As described above, in the screen device 40, when adjustment by truncation of the height dimension at the construction site or the like is required, the upper slide guide frame 44 is detached from the screen mounting frame 43 by releasing the connection between the first rigid units 48. It can be taken out and can be taken out at any position within the length of the screen mounting frame 43 and is easy. The length filling operation of the screen device 40 is facilitated.

  Further, since the lower slide guide frame 45 is the slide guide frame 1 shown in FIGS. 1 to 5 in the screen device 40, an external force acts in a direction intersecting the front and back direction of the screen 31 as shown in FIG. Even if the gap 32 is formed between the lower end of the screen 31 and the surface of the bridging portion 3 of the rigid unit 5 forming the lower slide guide frame, the gap 32 can be hidden by the long gap suppressing member 6. it can. Moreover, the flexibility of the lower slide guide frame 1 is not impaired by the attachment of the long gap suppressing member 6.

  FIGS. 8A, 8B, and 8C are a front view, a plan view, and a side view, respectively, showing a rigid unit that forms the second embodiment of the slide guide frame of the present invention.

  The rigid unit 60 shown in FIGS. 8A, 8B, and 8C is based on the structure of the first rigid unit 48 that forms the upper slide guide frame 44 of the screen device 40 shown in FIG. Therefore, in FIGS. 8A, 8B, and 8C, portions common to the rigid unit 5 shown in FIG. 2 and the first rigid unit 48 shown in FIG. Then, the explanation is omitted.

  The rigid unit 60 includes a pair of side wall portions 2 arranged opposite to each other, a bridge portion 3 that connects both side wall portions 2 to each other, and a holding mechanism 4 that maintains linearity. In addition, the rigid unit 60, like the rigid unit 5 shown in FIGS. 2A, 2B, and 2C, is rotatably connected between two adjacent ones to form a slide guide frame. . That is, in two adjacent rigid units 60, the rotation shaft 8 is inserted into the through hole 10 from the back side of the second portion 11, and one of the two rigid units 60 is rotatably connected to the other. Is formed. Therefore, the slide guide frame 1 has flexibility due to the rotatable connection between the two adjacent rigid units 60 and can be held linearly by the holding mechanism 4.

  In the rigid unit 60, the holding mechanism 4 is the same as the holding mechanism provided in the first rigid unit 48 shown in FIG. That is, as described with respect to the first rigid unit 48 shown in FIG. 7, the holding mechanism 4 provided in the rigid unit 60 is provided directly below the one end 3 a located on the rotating shaft 8 side in the bridging unit 3. The step portion 61 is formed to protrude outward from the one end portion 3 a of the bridging portion 3. The step portions 61 are provided as a pair at both end portions in the width direction of the bridging portion 3.

  In such a holding mechanism 4, the other end portion 3 b located on the through hole 10 side in the bridging portion 3 of one of the two rigid units 60 is superposed on the stepped portion 61. Accordingly, the rotation of the rigid unit 60 is stopped. For this reason, the slide guide frame can maintain linearity.

  Further, in the rigid unit 60, specifically, the bridging portion 3 is a range from one end of the rotation shaft 8 located on the one end portion 15 side in the first portion 9 to the through hole 10 in the second portion 11. In the height direction of the side wall portion 2, the side wall portion 2 is disposed at a height equal to the distance from one end located on the back surface side of the bridging portion 3 to the center of the rotation shaft 8. Further, in the bridging portion 3, specifically, the groove member 23 for attaching the gap suppressing material 6 is within a range from the center of the rotation shaft 8 to the vicinity of the first boundary portion 13 in the second portion 11. A pair of bridge portions 3 are provided at both ends in the width direction.

  Specifically, the groove member 23 includes a first piece 24 protruding from the back surface of the first portion 9 located above the bridging portion 3 to the inside of the side wall portion 2, and a surface of a portion near the center of the bridging portion 3. And a second piece 25 having an L-shaped cross section that extends upright and bends toward the first piece 24 side. In the groove member 23, the tip of the first piece 24 and the tip of the portion bent toward the first piece 24 of the second piece 25 are spaced apart from each other by a certain distance and are opposed to each other. As a result, the groove member 23 forms a groove 26 having a C-shaped cross section that opens in the height direction of the side wall portion 2 with the surface of the bridging portion 3.

  The first piece 24 that can be provided in the rigid unit 60 also has an L-shaped cross section that extends upright from the surface of the bridging portion 3 and bends toward the second piece 25, similarly to the second piece 25. It does not matter even if it has.

  Also in the slide guide frame formed of such a rigid unit 60, the long gap suppressing member 6 is provided over the entire length of the slide guide frame with the base material 29 inserted into the groove member 23. Specifically, the base material 29 is inserted into the groove 26 of the groove member 23, arranged across the groove member 23, and the gap suppressing member 6 is attached to the slide guide frame.

  The gap suppressing member 6 attached to the slide guide frame is provided as a pair at both ends in the width direction of the bridging portion 3 of the rigid unit 60, and is disposed along the back surfaces of the side wall portions 2 of the rigid unit 60. The mohair 30 is arranged upright from the surface of the bridging portion 3. Specifically, the mohair 30 protrudes outside the groove 26 from a portion of the groove member 23 that opens in the height direction of the side wall 2 of the rigid unit 60.

  Accordingly, an external force due to wind or the like is applied in a direction intersecting the front and back surfaces of the screen 31, and the screen 31 is bent so as to swell in a direction to receive the external force. Even if a relatively large gap 32 is formed between the lower end of the screen 31 and the surface of the bridging portion 3 of the rigid unit 60, the gap 32 is hidden by the mohair 30. For this reason, the gap 32 is prevented from communicating with the outside on the front and back of the screen device, and problems such as light leakage and invasion of insects are solved.

  Moreover, the bending direction of the slide guide frame coincides with the direction in which the base material 29 included in the gap suppressing member 6 can be bent. Therefore, even if the gap suppressing member 6 is a long member, it follows the bending of the slide guide frame, bends easily at any part, and inhibits the bending when the slide guide frame is bent. There is no tension. The flexibility of the lower slide guide frame is not impaired by the attachment of the long gap suppressing member 6.

  In the rigid unit 60, unlike the rigid unit 5 shown in FIGS. 2 (a), (b), and (c), both the rotation shaft 8 and the through hole 10 are not at the center in the height direction of the side wall portion 2, It is arranged on the lower side. In this relation, at the one end portion 15 of the first portion 9 and the one end portion 21 of the second portion 11, the first notch cut obliquely outward from the lower side in the height direction of the side wall portion 2 to the upper side from the center. The part 62 and the 2nd notch part 63 are formed. Even if both the rotation shaft 8 and the through hole 10 are arranged on the side wall portion 2 on the lower side in the height direction by the first cut portion 62 and the second cut portion 63 as described above, the slide guide When the frame is bent, exposure of a portion of the first portion 9 located on the one end portion 15 side can be suppressed.

  As mentioned above, although this invention was demonstrated along embodiment, this invention is not restrict | limited by embodiment. The details of the configuration and structure of each part can be appropriately selected in consideration of the function to be performed by each part.
