  The winding pipe 9 has one end of the screen 4 attached and is suspended so as to be able to be wound, suspended from the winding pipe 9, and the screen 4 folded back via the weight bar 5 functioning as a weight member. The other end is attached to the fixed pipe 7. A roller 15 rotatably supported at both ends of the weight bar 5 is inserted through the lower end of the screen 4 suspended between the winding pipe 9 and the fixed pipe 7. Therefore, the screen 4 is stretched based on the weight of the weight bar 5.

  When the operation cord 3 is operated to rotate the winding pipe 9 in the screen winding direction, the weight bar 5 is raised, and when the winding pipe 9 is rotated in the screen rewinding direction, the weight bar 5 is lowered.

  Further, in the winding pipe 9, a spring motor for reducing the operation force at the time of winding up the screen 4 is accommodated at the left end side thereof, and a stopper device for preventing lowering of the weight of the screen 4 at the right end side. Not shown).

  In the screen 4, a transmitting portion 4 b which partially transmits light and a light shielding portion 4 a which blocks light are alternately formed in, for example, a stripe shape, and the screen 4 is suspended and supported in a state of double overlapping. Therefore, the light collecting amount can be adjusted by relatively moving the front and rear screens 4 in the vertical direction by the operation of the operation code 3 and adjusting the overlapping state of the transmitting portion 4 b and the light shielding portion 4 a.

  Next, specific configurations of the operation plate 6 and the periphery thereof will be described with reference to FIG.

There is. Therefore, the operation plate 6 is supported rotatably relative to the operation pulley 10 and the winding pipe 9. The elongated hole-shaped rotation receiving portion 17 is formed so as to be able to rotate relative to a support shaft 16 described later, and is regulated so as not to rotate relative to a predetermined angle or more. The shape of the support plate 8 of the present embodiment is substantially the same as the shape of the operation plate 6 of the present embodiment, and the rotation receiving portion 17 (shown in the drawing) similar to the operation plate 6 of the present embodiment. Is provided.

  Further, the operation plate 6 is provided with a rotation shaft hole 23 through which the support shaft 16 is inserted so that the operation plate 6 performs a pendulum operation with the support shaft 16 extending from the support member 2a as a rotation shaft. It is done. Similarly, in the support plate 8 as well, the pivot shaft hole 23 through which the pivot shaft 16 is inserted above the outdoor side so that the support plate 8 performs a pendulum operation with the pivot shaft 16 extending from the support member 2b as a pivot shaft. Provided (not shown). The spindles 16 may be provided on the operation plate 6 and the support plate 8, and the pivot shaft holes 23 may be provided on the support members 2a and 2b.

  Accordingly, with the operation plate 6 and the support plate 8 of the present embodiment, with the support shaft 16 as a rotation shaft, the operation pulley 10 and the winding are performed in a state where the rotation range is restricted by the long hole-like rotation receiving portion 23 Relative rotation with respect to the pipe 9 is possible.

  Another component (not shown) having a code cover 20 is provided on the fixed shaft 11 above the operation plate 6. The cord cover 20 may be attached to the support member 2a. Below the operation plate 6, a hole 22 capable of supporting the fixed pipe 7 is provided.

The fixed pipe 7 may be rotatably attached to the operation plate 6 or may be non-rotatably attached. The height of the weight bar 5 in the lower limit state of the screen 4 can be finely adjusted by providing a ratchet mechanism or the like which is rotatable and can be held at the rotational position.

  On the front end side of the operation plate 6, two cord guide portions 12 and 13 protruding from the plate surface are provided. The endless operation cord 3 suspended from the operation pulley 10 is guided so as to be suspended from between the two cord guiding portions 12 and 13 (see FIG. 4).

  When operating the operation code 3, the operation plate 6 configured in this way operates the pendulum so that the distance between the relatively movable double screens 4 is increased. In particular, the operation plate 6 performs a pendulum operation so that the positional relationship between the winding pipe 9 and the fixed pipe 7 changes between at rest and at the time of operation. And the interval at the time of operation of double screen 4 is constituted so that it may become larger than the interval at the time of rest.

  More specifically, the operation of the operation plate 6 will be described with reference to FIG. First, referring to FIG. 4A, the operation plate 6 is supported so as to be rotatable relative to the operation pulley 10 and the winding pipe 9, and each of the lower limit position, the intermediate position and the upper limit position of the weight bar 5 is provided. In the direction in which the front and rear screens 4 are in close contact with the operation plate 6 with its own weight (the weight of the screen 4, weight bar 5, operation plate 6, support plate 8 and fixed pipe 7). Clockwise) and torque works. The operation code 3 is suspended based on the code guiding portions 12 and 13.

  In this stationary state, when the weight bar 5 is at the lower limit position, or when the screen 4 is wound around the winding pipe 9 at the intermediate position and the upper limit position of the weight bar 5, the double screen 4 is It stabilizes in the position (the space | interval d1 of the double screen 4) which makes a space | interval approach or close_contact | adherence. Therefore, it is possible to shift the transmitting portion 4b and the light shielding portion 4a of the double screen 4 to be in a semi-transmissive state, or to make the transmitting portion 4b and the light shielding portion 4a of the screen 4 to be in a light shielding state. In particular, it is possible to improve the light shielding property when the light shielding state is made. In the present embodiment, each end of the screen 4 is attached to the winding pipe 9 and the fixed pipe 7 so as to be in the light shielding state in the lower limit state of the weight bar 5.

  Next, referring to FIG. 4B, when the operation code 3 is operated to raise the weight bar 5 from the state where the weight bar 5 is at the lower limit position or the middle position, for example, the screen 4 is wound around the winding pipe 9 To be taken. At this time, a clockwise torque is applied to the operation plate 6 through the code guide 12 by the operation code 3 to cause the operation plate 6 to perform a pendulum operation, and the interval d2 at the time of operation of the double screen 4 is at rest. It is configured to be larger than the interval d1. Therefore, there is no risk of damaging the screen 4 because the double screen 4 does not rub during the lifting operation, or the friction is either partial during lifting or lowering, or the frictional force is reduced for relative movement.

  Similarly, referring to FIG. 4C, for example, when the operation code 3 is operated to lower the weight bar 5 from the state where the weight bar 5 is at the middle position or the upper limit position, it is wound around the winding pipe 9 The screen 4 is lowered. At this time, a clockwise torque is applied to the operation plate 6 through the code guide 12 by the operation code 3 to cause the operation plate 6 to perform a pendulum operation, and the interval d3 at the time of operation of the double screen 4 is at rest. It is configured to be larger than the interval d1. Accordingly, even in the lowering operation, the screen 4 does not rub, or even if friction is caused, the screen 4 is not damaged because the screen 4 moves in part as it is moving up and down, or the friction is reduced and the relative movement is performed. In addition, even if friction generate | occur | produces in a part of upper limit vicinity which the cloth | dough of the screen 4 rolls, it acts in the direction to which frictional force is reduced.

  As described above, when stationary, the operation code 3 loses tension and the operation plate 6 rotates in the direction in which the double screen 4 approaches due to its own weight, so the double screens 4 are close or close It is possible to improve the light shielding property when the light transmitting portion 4b of the screen 4 and the light shielding portion 4a are made to coincide with each other to make the light shielding state.

  In addition, in the roll screen 1 of the present embodiment, in a state (lower limit state) in which the screen 4 is rewound by the winding pipe 9, the transmitting portion 4 b and the light shielding portion 4 a in the double screen 4 are shielded. So that external light incident from the gap between the winding pipe 9 and the fixed pipe 7 can be completely shielded, the winding pipe 9 is superimposed on the screen 4 and has a predetermined width substantially the same as the width of the screen 4 A length of shielding cloth 18 is attached. Hereinafter, the shielding cloth 18 of each embodiment will be described in detail.

Again, one end is attached. Accordingly, the other end of the shielding cloth 18 is suspended following the hanging direction of the screen 4. Although the other end of the shielding cloth 18 can be fixed on the screen 4 by welding or the like, one end of the shielding cloth 18 is simply superimposed on the screen 4 with respect to the winding pipe 9 as in this example. Assembling can be improved by only attaching them together.

  Further, at the time of winding by the winding pipe 9, the shielding material 18 is wound together with the screen 4, and at the time of rewinding by the winding pipe 9, it is rewound following the rewinding of the screen 4. Therefore, the shielding cloth 18 does not inhibit the operability of the pendulum operation as compared with, for example, a configuration in which an outer wall having a shielding effect is provided between the operation plate 6 and the support plate 8, and There is no loss of aesthetics.

  The shielding cloth 18 of the first embodiment may have a length capable of closing the gap between the winding pipe 9 and the fixed pipe 7. More specifically, as shown in FIG. 5, among the tangents in contact with the outer peripheral surface of the winding pipe 9 and the outer peripheral surface of the fixed pipe 7, on the plane perpendicular to the longitudinal direction of the winding pipe 9 The length is preferably sufficient to close the gap SA formed between two tangents L1 and L2 intersecting between the winding pipe 9 and the fixed pipe 7.

(Shielding fabric of another embodiment)
The shielding cloth 18 having a length capable of closing the gap between the winding pipe 9 and the fixed pipe 7 may be configured in another embodiment. 6 (a) and 6 (b) are enlarged views seen from the side illustrating the shielding cloth 18 of Examples 2 and 3 in the rolling screen 1 of the first embodiment of the present invention, respectively.

  For example, as shown in FIG. 6A, as the shielding cloth 18 of the second embodiment, one end of the shielding cloth 18 is removed by welding or the like from the upper end of the screen 4 attached to the winding pipe 9 at a predetermined position 18a. It can be configured to be worn. Accordingly, the other end of the shielding cloth 18 of Example 2 is suspended following the hanging direction of the screen 4. The other end of the shielding cloth 18 of the second embodiment can be fixed on the screen 4 by welding or the like.

  Alternatively, as shown in FIG. 6B, as the shielding cloth 18 of the third embodiment, the shielding cloth 18 can be attached and attached at the upper end position 18b of the screen 4. In addition, in the case of Examples 2 and 3, the assembling process for fixing the screen 4 and the shielding cloth 18 by welding or the like is added, from the viewpoint of assemblability compared to the case of the shielding cloth 18 of Example 1. Although it will be inferior, for example, in comparison with a configuration in which an outer wall having a shielding effect is provided between the operation plate 6 and the support plate 8, the shielding cloth 18 does not inhibit the operability of the pendulum operation and There is no loss of assemblability and aesthetics.

  As described above, according to each example of the present embodiment, in the state where the screen 4 is unwound by the winding pipe 9, the external light from the gap generated between the winding pipe 9 and the fixed pipe 7 is effectively It is possible to improve the light shielding property when the light shielding portion 4b and the light shielding portion 4a in the relatively movable double screen 4 are made to coincide with each other to make the light shielding state.

  The roll screen shown in FIGS. 9A and 9B is a further modification of the roll screen 101 of the second embodiment, and the other end of the screen 4 having one end attached to the take-up pipe 9 is a second modification. The fabric presser 52 is engaged and attached not by the fixed pipe 7 as in the second embodiment but by the engaging portion 51 provided on the outer side surface of the mounting frame 2.

  Accordingly, in the roll screen shown in FIGS. 9A and 9B, although not shown, the winding pipe 9 is rotatably supported between the support members 2a and 2b, and the right end portion of the winding pipe 9 is An operation pulley 10 is provided, and an endless operation cord 3 hung around the operation pulley 10 is suspended.

  The other end of the screen 4 hanging down from the winding pipe 9 and folded back via the weight bar 5 functioning as a weight member is attached to the engaging portion 51 of the mounting frame 2. At the lower end portion of the screen 4 hanging down between the winding pipe 9 and the engaging portion 51, rollers 15 rotatably supported at both ends of the weight bar 5 are inserted. Therefore, the screen 4 is stretched based on the weight of the weight bar 5, and operates in the same manner as the roll screen 101 of the second embodiment.

  Here, in the roll screen shown in FIG. 9A, one end of the screen 4 and one end of the shielding cloth 18 are stapled at the engagement position 53 on the cloth presser 52 engaged with the engagement portion 51 of the mounting frame 2. It is locked by etc. In the example shown in FIG. 9A, an example is shown in which the shielding cloth 18 is attached to the engaging portion 51 so that the shielding cloth 18 is located outside the screen 4. You may attach to the engaging part 51 so that 18 may be located. However, by configuring the shielding cloth 18 to be located on the outdoor side of the screen 4, it is possible to hide the cloth presser 52 from the outside by the shielding cloth 18, which is preferable in that the aesthetic appearance is maintained.

  The shielding cloth 18 is suspended from the position of the engaging portion 51 of the mounting frame 2 with a length that can prevent external light from being incident from the gap between the mounting frame 2 and the winding pipe 9. Thus, according to the embodiment shown in FIG. 9A, in the state where the screen 4 is rewound by the winding pipe 9, the external light from the gap generated between the mounting frame 2 and the winding pipe 9 is It is possible to improve the light shielding property when the light shielding portion 4b and the light transmitting portion 4a in the relatively movable double screen 4 are made to coincide with each other so as to be shielded.

  On the other hand, in the roll screen shown in FIG. 9 (b), one end of the screen 4 is folded back on the fabric presser 52 engaged with the engaging portion 51 of the mounting frame 2 and engaged by a stapler or the like at the engagement position 53. It is done. In the example shown in FIG. 9B, the screen 4 is folded back from the indoor side toward the outdoor side, but it may be folded back from the outdoor side to the indoor side.

  The length of the end of the screen 4 being folded back and hanging down from the fabric presser 52 can prevent external light from being incident from the gap between the mounting frame 2 and the winding pipe 9 in the light shielding portion 4a of the screen 4 It is adjusted to be the position to be. Thus, according to the embodiment shown in FIG. 9 (b), in the state where the screen 4 is rewound by the winding pipe 9, the external light from the gap generated between the mounting frame 2 and the winding pipe 9 is It is possible to improve the light shielding property when the light shielding portion 4b and the light transmitting portion 4a in the relatively movable double screen 4 are made to coincide with each other so as to be shielded. In particular, according to the embodiment shown in FIG. 9 (b), one end of the screen 4 is folded back from the cloth presser 52 by using the light shielding portion 4 a of the screen 4 without using the shielding cloth 18. Therefore, it is possible to realize cost reduction and high quality by reducing the number of parts, and by providing a shielding effect with the fabric of the screen 4 to prevent the deterioration in appearance that may occur when different fabrics are used It can also be done.

  Further, even in the case of using the shielding cloth 18 or in the case where one end of the screen 4 is folded back and suspended, the winding pipe 9 among tangents in contact with the outer peripheral surface of the winding pipe 9 and the outer surface of the mounting frame 2. It is sufficient to close the gap formed between the two tangents intersecting between the winding pipe 9 and the mounting frame 2 on a plane perpendicular to the longitudinal direction of the frame.

  As described above, according to the roll screen of each embodiment, the winding pipe 9 and the fixing pipe 7 or the winding pipe 9 and the attachment frame 2 with the screen 4 being rewound by the winding pipe 9. By providing the shielding cloth 18 capable of closing the gap generated between the two, it is possible to effectively shield the external light from the gap.

  Moreover, according to the roll screen of each embodiment, the shielding portion that folds back and hangs the shielding cloth 18 and one end of the screen 4 is provided to follow the hanging of any one of the dual screens 4 that can move relatively. The external light can be effectively shielded without impairing the appearance.

  In addition, according to the roll screen of each embodiment, the shielding fabric 18 is attached together with attachment of either one of the double screen 4 so that the assemblability and the appearance are not impaired. Light can be shielded effectively.

  In particular, when the shielding cloth 18 is provided as shown in Example 1 of the first embodiment or Example 2 of the second embodiment, the shielding cloth 18 is attached together with the attachment of the screen 4. There is no loss of assemblability and aesthetics.

  When the shielding cloth 18 is provided on the side of the winding pipe 9 as shown in Example 1 of the first embodiment, the shielding cloth 18 is wound along with the winding of the screen 4 when the winding pipe 9 is wound. Since the shielding cloth 18 is unwound along with the unwinding of the screen 4 at the time of rewinding by the winding pipe 9, the shielding cloth 18 does not inhibit the operability of the pendulum operation.

  Moreover, according to the roll screen of each embodiment, the gap between the take-up pipe 9 and the fixed pipe 7 or the gap between the take-up pipe 9 and the mounting frame 2 can be closed. The external light can be effectively shielded irrespective of the patterns of the transmission part 4b of the screen 4 and the light shielding part 4a. In particular, the winding pipe on a plane perpendicular to the longitudinal direction of the winding pipe 9 among tangents contacting each of the outer peripheral surface of the winding pipe 9 and the outer peripheral surface of the fixed pipe 7 (or the outer surface of the mounting frame 2) If the length is sufficient to close the gap SA formed between the two tangents L1 and L2 crossing between the H.9 and the fixed pipe 7 (or the mounting frame 2), the length should be longer than this. Since it can be unnecessary, there is no adverse effect on the winding diameter of the winding pipe 9 or the adjustment of the light collection amount by the transmitting portion 4 b and the light shielding portion 4 a.

  Although the present invention has been described above by taking the example of the specific embodiment, the present invention is not limited to the example of the above embodiment, and various modifications can be made without departing from the technical concept thereof. For example, in each embodiment, although the indoor side and the indoor side were specified and explained, the indoor side and the indoor side may be installed in the opposite direction.

  Moreover, in the example of each embodiment mentioned above, the transmission part 4b which transmits a part of light, and the light-shielding part 4a which shields light are alternately formed in stripes as double screen 4 which turned back one sheet of screens. Although the example described above has been described, the present invention is applicable to a roll screen using a dual screen 4 even if the transmission portions 4 b and the light shielding portions 4 a are not alternately formed.

  According to the roll screen of the present invention, in the state where the screen (texture) is unwound by the winding pipe, the external light from the gap generated between the winding pipe and the fixed pipe (or the mounting frame) is effectively effective. It is useful for the application of a roll screen using a dual screen, since it is possible to improve the light blocking property when the light transmitting part and the light shielding part in the dual screen capable of shielding and moving relatively are made to coincide with each other to make the light shielding state. It is.
