Japanese Utility Model Publication No.59-80093

  When a roll type screen is provided on the skylight, it is necessary to install the roll shaft away from the side edge of the skylight by the thickness of the roll. However, in the invention described in Patent Document 1, since a plurality of sheets are connected to form a single cloth-like body, the roll thickness becomes large when the cloth-like body is wound around one roll means. Then, since it gives the occupant a feeling of pressure, it is not only aesthetically unfavorable, but the gap between the window frame and the sheet becomes large, and the risk of sunlight leakage and insect invasion increases. In addition, since any sheet always covers the skylight, the ventilation function is hindered in the openable skylight.

  On the other hand, two types of screens (sheets) are independently wound on different roll means, and moving means are provided on each of them, thereby reducing the roll thickness and enabling the release state to exhibit the ventilation function. However, such a configuration increases the cost.

  As shown in FIG. 3, the first screen 3 arranged on the right side in the drawing is pulled out, and the upper end side 31 of the projection 29 of the first screen 3 corresponds to the detection of the sensor 30 for the first screen 3 on the left side in the drawing. When contacting the lower end side 32 of the part 14, the motor 7 stops and the first screen 3 is prevented from being pulled out further. Similarly, the second screen 5 arranged on the left side in the drawing is pulled out, and the upper end side 31 of the projection 29 of the second screen 5 corresponds to the lower end of the detection unit 14 of the sensor 30 for the second screen 5 on the right side in the drawing. When the side 32 is touched, the motor stops and the second screen 5 is prevented from being pulled out further. Therefore, the protrusion 29 of the first screen 3 is aligned with the detection unit 14 for the first screen 3 in the lateral direction, but is shifted from the detection unit 14 for the second screen 5, and the second screen 5 is aligned with the detection unit 14 for the second screen 5 in the lateral direction, but is offset from the detection unit 14 for the first screen 3.

  When the protrusion 29 and the detection unit 14 come into contact with each other, the detection unit 14 rotates about the pin 34 because the upper end side 33 thereof is fixed by the pin 34. Therefore, it can be seen that the first or second screen 3 or 5 has reached the maximum drawing position. The detection unit 14 may be biased by a spring in a direction in which the corresponding protrusion 29 exists so that the detection part 14 returns to the original position when the corresponding protrusion 29 is detached.

  Next, the moving means 8 will be described with reference to FIGS. 2 and 3 are a plan view and a cross-sectional view of the screen device 1 in which the main part and the like of the guide rail 2 are omitted.

  The moving means 8 includes a motor 7 which is a single driving source for pulling out the first and second screens 3 and 5. Instead of the motor 7, a known manual driving means may be provided.

  The moving means 8 further includes a pulley 43 driven by the motor 7, two wires 44 and 45 wound around the pulley 43, and the wires 44 and 45 are annularly arranged around the opening of the window frame. And four wire guides 46 disposed on the surface.

  The pulley 43 receives power from the motor 7 and rotates. The pulley 43 is reversed by changing the rotation direction of the motor 7. The surface of the pulley 43 on which the wires 44 and 45 are wound is a cylindrical side surface, and the circumferential length is constant. The pulley 43 is arranged on the outer side of the second roll device 6 in the front-rear direction, that is, on the opposite side to the direction in which the second screen 5 is pulled out with respect to the second roll device 6, and both guide rails 2 in the lateral direction. It is desirable to be arranged at approximately the center between them. Note that the pulley 43 may be disposed outside the first screen 3.

  Each of the four wire guides 46 is disposed substantially on the extension line of the guide rail 2 and outside the first and second roll devices 4 and 6. The two wire guides 46 installed in the lateral direction of the pulley 43 are preferably aligned with the pulley 43 in one row in the lateral direction. Each wire guide 46 is desirably provided with an upper pulley 47 and a lower pulley 48 in the vertical direction, and both pulleys 47 and 48 are rotatable in opposite directions. Each upper pulley 47 guides one wire 44, and each lower pulley 48 guides the other wire 45.

  Each of the two wires 44 and 45 is fixed to the pulley 43 at both ends, and the both ends are wound around the pulley 43 a predetermined number of times. One wire 44 is wound or wound around the pulley 43 from both ends in the front-rear direction, and the other wire 45 is wound or wound around the pulley 43 from both ends in the front-rear direction. Yes. The position where the wires 44 and 45 are wound or unwound may be divided into an inner side and an outer side with respect to a line connecting the pulley 43 and the adjacent wire guide 46. In this embodiment, the position is shifted by approximately 180 ° on the circumference of the side surface of the pulley 43. Further, the wires 44 and 45 are bent by the four wire guides 46, and the portions extending in the vicinity of both the guide rails 2 and the first screen 3 overlap each other. Accordingly, in the present embodiment, the wire 44 has a pentagonal shape in which one side of a rectangle or square is bent outward, and the wire 45 has a pentagonal shape in which one side of the rectangle or square is bent inward. With the above configuration, when the pulley 43 rotates in one direction, the pentagonal annular portions of the two wires 44 and 45 move in opposite circumferential directions.

  Referring again to FIG. 1, first and second disengagement members 9, 10 are mounted on two wires 44, 45, respectively. When the first and second disengagement members 9 and 10 attached to one wire 44 move along the guide rail 2, the first and second disengagement members attached to the other wire 45 9 and 10 are arranged symmetrically with respect to the center line in the front-rear direction. The first and second disengagement members 9 and 10 are made of metal parts and are attached to the wires 44 and 45 by caulking. The distance along the wires 44 and 45 between the first and second engagement / disengagement members 9 and 10 provided on the same wire 44 and 45 is such that the first and second screens 3 and 5 are the first and second. It is more than the distance between the two horizontal bars 18 in the state accommodated in the roll, that is, more than the opening width in the front-rear direction. The first and second engagement / disengagement members 9 and 10 can enter the upper wire groove 25 and the lower wire groove 26 of the slider 20, but are sized to engage with the washer 22. In FIG. 1, in order to explain the arrangement of the first and second engagement / disengagement members 9 and 10, the wires 44 and 45 are drawn in a shifted manner, but in reality, the wires 44 and 45 are not shown in FIG. As shown, on the second roll device 6 side, they are stretched from opposite sides of the side surface of the pulley 43 to reach the wire guide 46, and other portions overlap each other vertically.

  Next, with reference to FIG. 1, the operating condition of the screen apparatus 1 concerning this invention is demonstrated.

  The screen device 1 is operated by a remote controller (not shown) or a wired operation panel (not shown) attached to the wall of the room.

  When the motor 7 is operated, the pulley 43 rotates. When the pulley 43 rotates clockwise, the portion of the wire 44 positioned on the right side of the pulley 43 is wound around the pulley 43 and the portion wound around the pulley 43 is unwound from the left side. Since the length of the portion to be wound is equal to the length of the portion to be unwound, the annular portion of the wire 44 rotates clockwise while maintaining the annular shape. At this time, the portion of the other wire 45 located on the left side of the pulley 43 is wound around the pulley 43, and at the same time, the portion wound around the pulley 43 is unwound from the right side. Since the length of the portion to be wound is equal to the length of the portion to be unwound, the annular portion of the wire 45 rotates counterclockwise while maintaining the annular shape.

  When the pulley 43 rotates counterclockwise, the movement of one wire 44 and the other wire 45 is reversed. That is, one wire 44 is wound around the pulley 43 at the portion located on the left side of the pulley 43, and at the same time, the portion wound around the pulley 43 is unwound from the right side. Since the length of the portion to be wound is equal to the length of the portion to be unwound, the annular portion of the wire 44 rotates counterclockwise while maintaining the annular shape. At this time, the portion of the other wire 45 located on the right side of the pulley 43 is wound around the pulley 43, and at the same time, the portion wound around the pulley 43 is unwound from the left side. Since the length of the portion to be wound is equal to the length of the portion to be unwound, the annular portion of the wire 45 rotates clockwise while maintaining the annular shape.

  Since the circumference of the surface of the pulley 43 around which the wires 44 and 45 are wound is constant, the moving speeds of both the wires 44 and 45 are equal to each other. Then, the first and second engagement / disengagement members 9 and 10 on one wire 44 are moved at least along the guide rail 2, and the first and second engagement / disengagement members 9 on the other wire 45. , 10 and moving symmetrically. Accordingly, the pair of first engagement / disengagement members 9 and the first slider 20 are engaged or disengaged simultaneously, and the pair of second engagement / disengagement members 10 and the second slider 21 are engaged or disengaged. Are performed simultaneously.

  FIG. 1B shows a state in which the first and second screens 3 and 5 are wound up. From this state, when the pulley 43 is rotated clockwise, the annular portion of one wire 44 moves clockwise and the annular portion of the other wire 45 moves counterclockwise. The member 9 simultaneously engages with two washers 22 attached to the first slider 20. Then, the pair of first sliders 20 slides on the guide rail 2 downward in FIG. 1 against the spring force of the first roll device 4, and the first screen 3 is pulled out. During this time, the two second disengagement members 10 are disengaged from the second slider 21 and are wound around the pulley 43 together with the wires 44 and 45. Therefore, the second screen 5 keeps being wound around the second roll device 6. FIG. 1A shows a state in which the first screen 3 is completely pulled out. At this time, the protrusion 29 of the horizontal bar 18 of the first screen 3 is engaged with the corresponding detection unit 14, and the motor 7 and the pulley 43 are stopped.

  When the pulley 43 is rotated in the reverse direction, that is, counterclockwise from the state of FIG. 1A, the annular portion of one wire 44 moves counterclockwise, and the annular portion of the other wire 45 moves clockwise. In addition, since the roll shaft 15 of the first roll device 4 is spring-biased in the direction of winding the first screen 3, the two first disengagement members 9 are connected to the two washers 22 of the first slider 20. It moves while maintaining the engagement. Then, the pair of first sliders 20 slides on the guide rail 2 upward in FIG. 1, the first screen 3 is wound up, and the state returns to the state of FIG. Until the first screen 3 is completely wound, the two second engagement / disengagement members 10 are separated from the second slider 21, so that the second screen 5 is wound around the second roll device 6. Keep the state.

  When the pulley 43 is further rotated counterclockwise from the state of FIG. 1B, the annular portion of one wire 44 moves counterclockwise and the annular portion of the other wire 45 moves clockwise. The pair of second engagement / disengagement members 10 are simultaneously engaged with the washer 22 of the second slider 21. Then, against the spring force of the second roll device 6, the pair of second sliders 21 slides on the guide rail 2 upward in FIG. 1, and the second screen 5 is pulled out. During this time, since the two first engagement / disengagement members 9 are separated from the first slider 20, the first screen 3 is kept wound around the first roll device 4. FIG. 1C shows a state in which the second screen is completely pulled out. At this time, the protrusion 29 of the horizontal bar 18 of the second screen 5 is engaged with the corresponding detection unit 14, and the motor 7 and the pulley 43 are stopped.

  When the pulley 43 is rotated in the reverse direction, that is, clockwise, from the state of FIG. 1C, the annular portion of one wire 44 moves clockwise and the annular portion of the other wire 45 moves counterclockwise. In addition, since the roll shaft 15 of the second roll device 6 is spring-biased in the direction of winding the second screen 5, the two second engagement / disengagement members 10 are connected to the two washers 22 of the second slider 21. It moves while maintaining the engagement. Then, the second slider 21 slides on the guide rail 2 downward in FIG. 1, the second screen 5 is wound up, and the state returns to the state of FIG. Until the second screen 5 is completely wound, the two first engagement / disengagement members 9 are separated from the first slider 20, so that the first screen 3 is wound around the first roll device 4. Keep the state.

  Although the description of the specific embodiment is finished above, the present invention is not limited to the above embodiment. For example, in the above embodiment, the moving means 8 includes the pulley 43 and the two wires 44 and 45 that are wound around the pulley 43 to form an annular shape. , 10 can be fixed, and other means that can be pushed and pulled along the guide rail 2 can be used. For example, the moving means 8 may be composed of a motor, a drive gear that is rotationally driven by the motor, a driven gear that meshes with the drive carrier, and a pair of rack belts that mesh with the driven carrier. Also, instead of the two annular wires 44 and 45 wound around the pulley 43 at both ends, two endless annular wires or belts bonded at both ends are used, and by frictional force between the pulleys, The wire or belt may be moved. Further, instead of the pulley 43 and the two wires 44 and 45, a sprocket and a pair of chains may be used.
