<Configuration of roll blind>
First, a schematic configuration of the roll blind according to the present embodiment will be described with reference to FIGS. FIG. 1 is a front view of the appearance of a roll blind with the entire screen extended. 2 is a view of the cross section taken along the arrow II-II in FIG. 1 from the left to the right, and FIG. 3 is the cross section taken along the arrow III-III in FIG. 1 from the left to the right. FIG. FIG. 4 is an enlarged perspective view of the folded portion of the screen at the position where the weight bar is mounted. FIG. 5 is a diagram in which the end fixing portion is disassembled as viewed from the left to the right. 1 to 5, the roll blind 1 mainly includes a frame 2, a take-up shaft 3, a screen 4, a weight bar 5, an operation cord 6, a sprocket 7, and an end fixing portion 8. Have.

  The frame 2 is a substantially cylindrical housing whose axial direction is arranged in the left-right direction of the example shown in the figure and whose rear side surface is open, and side brackets 21 are respectively provided at the opening portions at both ends and closed. Yes. In FIG. 2, two substantially T-shaped ribs can be locked above the frame 2 by a bracket (not shown), and this is fixed to a ceiling surface or the like via a mounting bracket 11 shown in FIG. .

  The winding shaft 3 is a substantially cylindrical shaft member disposed coaxially over the entire left and right direction inside the frame 2, and both ends thereof are supported by the side brackets 21 so that the winding shaft is The whole 3 is rotatable.

  The screen 4 is a cloth body having substantially the same width dimension (length in the left-right direction) as that of the winding shaft 3, and one upper end portion of the screen 4 is in the longitudinal direction (winding direction) perpendicular to the width direction. The other end of the shaft 3 is fixed to an end fixing portion 8 which will be described later. Further, the screen 4 has a light transmitting portion 41 having a predetermined width and a non-light transmitting portion 42 having a width larger than the predetermined width (about 1.5 times in this example) arranged alternately in the longitudinal direction. For example, as shown in FIG. 4, the translucent part 41 is a part that has a relatively high light transmittance by weaving with a low weaving density such as warp only or by weaving with a white thread or a thin thread. . For example, as shown in FIG. 4, the non-light-transmitting portion 42 is a portion where the light transmittance is relatively low by weaving with a high weaving density with warp and weft, or by weaving with a black thread or a thick thread. is there.

  The weight bar 5 includes a main roller 51, two face bars 52, and a weight bar cover 53. The main roller 51 is a substantially cylindrical shaft member that is slightly longer than the width dimension of the screen 4, and is hung inside the halfway position of the screen 4 in the longitudinal direction. The two face bars 52 are long members having substantially the same length as the main roller 51 and a semicircular cross-section in the axis orthogonal direction, and are slightly above the position where the main roller 51 is hooked (the screen 4 is extended). The side surfaces of the curved surfaces are arranged to face each other at a distance that is narrower than the diameter of the main roller 51 at the position. The weight bar cover 53 accommodates the main roller 51 and the two face bars 52 in its entirety and maintains the positional relationship between them while supporting both ends rotatably with respect to the main roller 51. Yes. In FIG. 4, in order to avoid the complexity of the illustration, the outline of the weight cover 53 is seen through with a dotted line, and only the curved portion of each face bar 52 is shown.

  The operation cord 6 is a string body in which a large number of balls 61 are fixed at equal intervals, and the entire operation cord 6 has an annular shape (endless shape). In FIG. 2, a positioning connector 62 is located inside the frame 2. Corresponding to this state, the connector 62 is not shown in FIG.

  The sprocket 7 is a substantially disk-shaped member capable of winding the operation cord 6 while retaining a predetermined number of balls 61 on the outer periphery thereof. In the illustrated example, the operation cord 6 is wound approximately 3/4 times. It is fixed to the right end of the winding shaft 3 in a rotated state. Most of the operation cord 6 that is not wound around the sprocket 7 is led out from a hanging hole 22 provided in the right end portion of the frame 2 and hangs down. The operator pulls down one of the front and rear sides of the operation cord 6 hanging from the frame 2 so that the sprocket 7 and the winding shaft 3 are wound in the winding direction (forward rotation in the illustrated example) or in the rewinding direction (illustrated). In the example, it can be rotated backward).

  Further, a sprocket cover 23 is provided on the outer peripheral side of the entire circumference of the sprocket 7 so as to correspond to a part within the angle range around which the operation cord 6 is wound. When the operation of the operation cord 6 is continued, the connector 62 comes into contact with the sprocket cover 23 to prevent further rotation of the sprocket 7 and the winding shaft 3. Thereby, the rotation limit position of the winding shaft 3 can be adjusted by adjusting the relative position of the connector 62. For example, although the balls 61-1 and 61-2 are engaged at the initial position shown in FIG. 2, if the height of the screen rear surface 4b is desired to be shortened by P1, for example, the upper engaging portion of the connector 62 is the ball 61. -5 is engaged, and the lower engaging portion is changed to engage with the ball 61-1. Conversely, when it is desired to increase the height of the screen rear surface 4b by P2, for example, the upper engaging portion of the connector 62 is engaged with the ball 61-3, and the lower engaging portion is engaged with the ball 61-4. It should be changed as follows. In the present embodiment, the rotation limit position of the winding shaft 3 is matched with the lower limit position of the screen 4. Note that the sprocket cover 23 and the connector 62 constitute a second lower end position adjusting portion described in each claim.

  The end fixing portion 8 has a winding plate storage portion 81 and an L-shaped angle 82. The wound plate storage portion 81 is a cylindrical portion having a substantially rectangular cross section formed integrally at the lower end portion of the frame 2 over the entire left and right direction, and a part of the lower side surface is open. The L-shaped angle 82 (hanging position defining member) is formed to have substantially the same width dimension (length dimension in the left-right direction) as the frame 2, and a vertical flat plate portion 82 a (protruding portion) arranged substantially vertically when attached. Winding by a plurality of bolts 10 in a state where the horizontal flat plate portion 82b that is in contact with the front side surface of the winding plate storage portion 81 and is disposed substantially horizontally covers the opening portion 81a on the lower side surface of the winding plate storage portion 81. It is fixed to the plate storage part 81. Further, as shown in FIG. 4, a substantially flat rectangular winding plate 9 is provided at the other upper end of the screen 4, and the winding plate 9 is wound around the screen 4 by an arbitrary number of turns. The other upper end of the screen 4 is securely fixed to the frame 2 by fixing the L-shaped angle 82 to the wound plate storage portion 81 while being stored in the rotation plate storage portion 81. At this time, the posture of the winding plate 9 around the winding axis is held inside the winding plate storage portion 81. In addition, the winding board storage part 81 comprises the 1st lower end position adjustment part as described in each claim.

<Operation of this embodiment>
In the roll blind 1 having the above configuration, the screen 4 is folded upward with the position where the weight bar 5 is hung as the lower end position, and the upper end (one upper end) of the rear side surface (hereinafter referred to as the screen rear surface 4b). Is fixed to the winding shaft 3, and the upper end portion (the other upper end portion) of the front side surface (hereinafter referred to as the screen front surface 4 a) is fixed to the end portion fixing portion 8. Since the entire weight bar 5 has an appropriate weight, both the screen front surface 4a and the screen rear surface 4b are suspended from the frame 2, and the entire screen 4 extends downward.

  In this state, when the operator operates the operation cord 6 to rotate the winding shaft 3 in the winding direction, the screen rear surface 4b is wound upward and the weight bar 5 is pulled up, so that the entire screen 4 is lifted. The deployment length of is shortened. When the operator operates the operation cord 6 to rotate the winding shaft 3 in the rewinding direction, the screen rear surface 4b is rewound downward and the weight bar 5 is pulled down. Is elongated. When the connector 62 rises and comes into contact with the sprocket cover 23, the operator can recognize that the screen 4 has reached the lower limit position because it stops without being operated any further. Even during these operations, the main roller 51 of the weight bar 5 rotates to move the hanging position, so that the weight bar 5 having a weight maintains the lower end position of the development area of the entire screen 4. In addition, the two face bars 52 of the weight bar 5 have their curved surfaces in contact (sliding contact) with the screen front surface 4a and the screen rear surface 4b so that the distance D2 between the two surfaces is narrower than the diameter of the main roller 51. Can be maintained.

  In the roll blind 1 according to the present embodiment, as described above, only the screen rear surface 4b moves up and down and the screen front surface 4a does not move up and down by the winding and unwinding operations of the winding shaft 3, so that the transparent surface between the two surfaces is transparent. The phase difference between the light part 41 and the non-light-transmissive part 42 changes. That is, by continuously performing the winding or rewinding operation, the overlapping area of the non-light-transmitting portion 42 between the two surfaces changes periodically, and light is transmitted through the entire development area of the screen 4. The amount can be changed periodically.

  Moreover, in the roll blind 1 of this embodiment, it is possible to adjust the lower end position of the screen 4 in each of the end fixing portion 8 and the winding shaft 3. First, in the end fixing portion 8, as shown in an enlarged view of FIG. 6, how much extra winding at the upper end of the screen front surface 4 a is wound around the winding plate 9 and stored in or released from the winding plate storage portion 81. The effective length of the entire screen 4 can be adjusted depending on whether or not For example, as shown in FIG. 6A, the initial state is a state in which the upper end portion of the screen front surface 4a is wound around the winding plate 9 twice as an extra winding. This is provided so as to correspond to the extra winding of the screen rear surface 4b. Further, the minimum winding adjustment pitch P3 is approximated to the minimum adjustment pitch P1 of the connector 62. When the excess winding of the winding plate 9 is unwound as shown in FIG. 6 (b) with respect to the initial state, the effective length of the entire screen 4 becomes longer (in the case of FIG. 6 (b), about P3 of the initial state). 4), the lower end position when the entire developed length of the screen 4 is extended, that is, the height of the weight bar 5 can be lowered. On the contrary, as shown in FIG. 6C, when the upper end of the screen front surface 4a is wound around the winding plate 9 by one turn from the initial state, the effective length of the entire screen 4 twice as large as P3. Becomes shorter, and the lower end position when the development length of the entire screen 4 is extended, that is, the height of the weight bar 5 can be increased. Note that this adjustment function can appropriately adjust the lower end position by appropriately changing the number of turns on the winding plate 9 even when the thickness of the screen 4 is different as shown in FIG.

  In addition, regardless of the number of windings of the screen front surface 4a, in order to maintain the storage of the winding plate 9 inside the winding plate storage part 81 even before the installation of the L-shaped angle 82, the dimensions of each part are set. Must be set in detail. For example, with respect to the thickness dimension T and the width dimension W (see FIG. 4) of the winding plate 9, the width dimension L1 of the opening 81a on the lower surface of the winding plate storage portion 81 and the width dimensions of the ribs 81b and 81c on the front and rear sides thereof. L2 and L3 (see FIG. 5) preferably have a relationship of L1 <W, and a relationship of L3 <L2 is also preferable. Further, in order to smoothly store the winding plate 9 in a state where the screen front surface 4a is wound into the winding plate storage portion 81, the dimensions may be set in a relationship of T <L1.

  For adjusting the lower end position of the screen rear surface 4b in the winding shaft 3, as shown in FIG. 3, for example, the winding is performed in a state where the upper end of the screen rear surface 4b is wound around the outer periphery of the winding shaft 3. The effective length of the entire screen 4 can be adjusted depending on whether the rotation limit position of the shaft 3 is set. For example, as shown in FIG. 3, when the rotation position where the material presser 31 is located directly below is set as the rotation limit position of the winding shaft 3 in the initial state, 3/4 rounds of extra windings are provided and wound. ing. On the other hand, as described above, the relative position of the connector 62 with respect to each ball 61 on the operation cord 6 is changed, and the rotational position where the fabric retainer 31 is further positioned counterclockwise is set as the rotational limit position of the winding shaft 3. When the adjustment is made, the effective length of the entire screen 4 is increased accordingly, and the lower end position when the developed length of the entire screen 4 is fully extended, that is, the height of the weight bar 5 can be lowered. Further, when the rotation position where the dough retainer 31 is positioned further clockwise than the position just below is set as the rotation limit position of the take-up shaft 3, the effective length of the entire screen 4 is shortened accordingly, and the development length of the entire screen 4 is reduced. The lower end position when fully extending, that is, the height of the weight bar 5 can be increased.

  As described above, the lower end position can be adjusted on each of the screen front surface 4a and the screen rear surface 4b, so that the lower end position can be arbitrarily adjusted when the development length of the entire screen 4 is extended, and the light transmission between the two surfaces at the lower limit position can be adjusted. It can adjust so that the phase difference of the part 41 and the translucent part 42 may be minimized. The adjustment of the lower end position of the take-up shaft 3 is not limited to the adjustment by the connector 62, but may be adjusted by providing a mechanical limit device by screw feeding or the like in the take-up shaft 3 instead of the connector 62. Good. In short, it is sufficient that the rotation limit position of the winding shaft 3 can be changed, and it is preferable that the position can be made the same as that of the adjusting unit 8.

  Further, when the L-shaped angle 82 is installed in the winding plate storage portion 81, the horizontal flat plate portion 82b that is horizontally disposed covers the opening 81a, so that the upper end portion of the screen front surface 4a can be securely fixed, The hanging position of the screen front surface 4a in the front-rear direction (horizontal direction) can be defined at the rear edge of the horizontal flat plate portion 82b. At this time, by placing the vertical flat plate portion 82a of the L-shaped angle 82 in contact with the front side surface of the winding plate storage portion 81, the hanging position in the front-rear direction of the screen front surface 4a can be easily and reliably defined.

<Features of this embodiment>
Here, in the roll blind 1 of the present embodiment, the light transmission amount in the entire development region of the screen 4 is periodically changed by continuously performing the winding or rewinding operation as described above. be able to. On the other hand, when it is desired to minimize (darken) the amount of light transmitted through the entire development area of the screen 4, the non-light-transmitting portion with respect to the light-transmitting portion 41 between the screen front surface 4a and the screen rear surface 4b. It is necessary to narrow the gap between the respective non-light-transmitting portions 42 when 42 is completely overlapped. That is, it is desirable to keep the distance D in the front-rear direction between the screen front surface 4a and the screen rear surface 4b as small as possible.

  On the other hand, in the weight bar 5, the two face bars 52 are in contact (sliding contact) with the screen front surface 4 a and the screen rear surface 4 b, respectively, so that the separation distance D between the two surfaces is always equal to that of the main roller 51. It is kept narrower than the diameter. However, the drooping position (4b-min, 4b-max) of the screen rear surface 4b varies greatly between the state in which the winding shaft 3 has wound the screen 4 the most and the state in which the screen 4 has been unwound most (range V in FIG. 3). reference).

  Therefore, in the present embodiment, the end fixing portion 8 is disposed on the lower side of the take-up shaft 3 (the same front side as the take-up shaft 3 in the horizontal direction with respect to the entire screen 4), so that the take-up shaft 3 However, the drooping position 4a on the front surface of the screen can be brought closest to the drooping position 4b-max on the rear surface of the screen when the screen 4 is unwound most and the developed length of the entire screen 4 is extended. As a result, the distance D from the drooping position 4a of the screen front surface at the end fixing portion 8 is the narrowest, and the gap between the non-light transmitting portions 42 of the screen front surface 4a and the screen rear surface 4b is narrowed to leak light. Can be suppressed most.

<Effect of this embodiment>
As described above, the roll blind 1 of the present embodiment has the end fixing portion 8 that fixes the upper end portion of the screen front surface 4a and defines the hanging position in the horizontal direction, and the end fixing portion 8 is wound up. It is arranged below the shaft 3 (on the same side as the winding shaft 3 in the horizontal direction with respect to the screen 4).

  As a result, the end fixing portion 8 is closest to the hanging position of the screen front surface 4a when the winding shaft 3 unwinds the screen 4 the most and extends the entire length of the screen 4 to the hanging position of the screen rear surface 4b. Can be made. As a result, it is possible to make the two surfaces that are folded back in a state where the entire screen 4 is fully extended be closest to each other.

  Further, particularly in the present embodiment, the end fixing portion 8 has a winding plate storage portion 81 capable of adjusting the lower end position of the screen 4. Thereby, the lower end position when the development length of the entire screen 4 is fully extended, that is, the height of the weight bar 5 can be adjusted according to the height of the window frame in which the roll blind 1 is actually installed. Further, the lower end position of the screen 4 can be adjusted also on the winding shaft 3. As described above, the lower end position can be adjusted on each of the screen front surface 4a and the screen rear surface 4b, so that the lower end position when the entire developed length of the screen 4 is fully extended can be arbitrarily adjusted, and the translucent portion between the two surfaces at the lower limit The phase difference between 41 and the light transmitting portion 42 can also be adjusted.

  In this embodiment, in particular, the screen 4 is provided with a substantially flat rectangular winding plate 9 at the upper end portion of the screen front surface 4a, and the winding plate 9 in a state where the screen 4 is wound is stored and the winding is performed. A winding plate storage portion 81 that can hold a posture around the axis is provided.

  Thus, the effective length of the entire screen 4 can be adjusted by adjusting how much the upper end of the screen front surface 4 a is wound around the winding plate 9 and stored in the winding plate storage portion 81, and the lower end position of the screen 4 can be adjusted. . With such a simple configuration with a small number of parts, it is possible to reliably fix the end of the screen 4 and adjust the lower end position of the screen 4. In addition, as a lower end position adjustment part, you may comprise by the winding shaft 3 and the 2nd winding shaft separate from (not shown in particular).

  In the present embodiment, in particular, the end fixing portion 8 has a detachable L-shaped angle 82, and the L-shaped angle 82 is the edge of the horizontal flat plate portion 82 b that is arranged substantially horizontally when attached, and the front surface of the screen. The drooping position of 4a is defined. Accordingly, by installing the vertical flat plate portion 82a of the L-shaped angle 82 in contact with the front side surface of the winding plate storage portion 81, the hanging position in the front-rear direction of the screen front surface 4a can be easily and reliably defined. Also, the position of the edge on the rear side of the horizontal flat plate portion 82b can be obtained by replacing the horizontal flat plate portion 82b with an L-shaped angle 82 having a different width dimension in the front-rear direction or by making the bolt hole a long hole extending in the front-rear direction. It is also possible to adjust the hanging position of the upper end portion of the screen front surface 4a. This front / rear adjustment function is suitable when the drooping position of the screen fluctuates, especially when it is desired to provide a longer adjustment margin by providing the winding shaft 3 with one or more extra turns in the initial state.

  In the present embodiment, in particular, the screen 4 has light-transmitting portions 41 having a predetermined width and non-light-transmitting portions 42 having a width wider than a predetermined width alternately arranged in the winding direction. As a result, by continuously performing the winding or rewinding operation, the overlapping area of the non-translucent portion 42 between the two surfaces changes periodically, and the light in the entire development region of the screen 4 is changed. The amount of transmission can be changed periodically.

  In the present embodiment, the winding plate 9 is provided at the end of the screen front surface 4a, and the winding plate storage portion 81 capable of storing the winding plate 9 is provided at the end fixing portion 8. Not limited. For example, as shown in FIG. 7A corresponding to the respective drawings in FIG. 6, the end portion of the screen front surface 4a may be fixed so as to be directly attached to the upper surface of the horizontal flat plate portion 82b of the L-shaped angle 82, Even in this case, the drooping position in the horizontal direction of the screen front surface 4a is defined, and the two surfaces folded back in a state where the entire screen 4 is fully extended can be brought closest to each other. Further, as shown in FIG. 7B, the end portion of the screen front surface 4a may be fixed so as to be directly attached to the rear side end portion of the frame 2, and in this case, the same effect as in FIG. Is obtained. Even when the winding plate storage portion 81 is provided, an opening 81a may be formed on the front side surface of the winding plate storage portion 81 as shown in FIG. In the portion fixing portion 8, the number of bent portions of the end portion of the screen front surface 4a can be increased, and the portion can be more reliably fixed.

<Modification>
The disclosed embodiments are not limited to the above, and various modifications can be made without departing from the spirit and technical idea thereof. Hereinafter, such modifications will be described.

  FIG. 8 corresponding to FIG. 3 shows a cross-sectional view of the frame 2A provided in the present modification. In FIG. 8, the present modification includes an end fixing portion 8A having a shape different from that of the above embodiment. In the above embodiment, the entire winding plate storage portion 81 is a cylindrical portion having a substantially rectangular cross section. However, in this modification, the ceiling 81Ad of the winding plate storage portion 81A is curved in a concave shape when viewed from the inside. The rib 81Ac on the front side of the opening 81Aa is disposed lower than the rib 81Ab on the rear side. A protrusion 81Ae protruding upward is provided at the edge of the rear rib 81Ab (the rear edge of the opening 81Aa). Further, instead of the L-shaped angle 82, a flat plate member 83 (hanging position defining member) whose center position in the front-rear direction protrudes upward is fixed so as to cover the opening 81Aa of the winding plate storage portion 81A.

  Here, in the case of the winding plate storage portion 81 of the above embodiment as a comparative example, the winding plate 9 is held in a posture as shown in FIG. 9A immediately before the L-shaped angle 82 is installed. . At this time, the front edge (the edge on the free end side) of the winding plate 9 comes into contact with the ceiling of the winding plate storage portion 81 due to the weight of the screen front surface 4a, while the winding plate is positioned lower than that. 9 is in a state in which the rear edge (the edge on the screen connection side) 9 is only engaged with the edge of the rear rib 81b. In this state, the rib 81b on the rear side becomes a simple cantilever and bends without being able to withstand the load (refer to the arrow in FIG. 9A) applied downward to the tip, As a result, the opening 81a is widened and the winding plate 9 is easily removed. That is, when the operator releases his / her hand before fixing with the L-shaped angle 82, the winding plate 9 easily falls off the winding plate storage portion 81 and falls together with the screen front surface 4a.

  On the other hand, in the case of the winding plate storage portion 81A of this modification, the winding plate 9 is held in the posture shown in FIG. 9B immediately before the flat plate member 83 is installed. At this time, the front side edge (the edge on the free end side) of the winding plate 9 is guided to the curved ceiling 81Ad (induction ceiling) of the winding plate storage portion 81A, and the front side rib at a relatively low position. While being locked to 81Ac (locking rib), the rear edge of the winding plate 9 (the edge on the screen connection side) is the edge of the rear rib 81Ab (projection rib) at a relatively higher position. It will be in the state lifted by this protrusion part 81Ae. In this state, the weight of the screen front surface 4a is added so as to compress the rib 81Ab on the rear side in the substantially horizontal direction via the protrusion 81Ae (see the arrow in FIG. 9B). In this case, the rear rib 81Ab can withstand the compressive load and does not bend, and as a result, accommodation of the wound plate 9 can be maintained.

  Further, the flat plate member 83 is installed so that the protruding portion 83a is brought into contact with the edge portion of the rib 81Ac on the front side, whereby the upper end portion of the screen front surface 4a can be securely fixed and the screen front surface 4a is suspended in the front-rear direction. The position can be defined easily and reliably. Since the flat plate member 83 does not have the vertical flat plate portion 82a in the L-shaped angle 82, even when the frame 2A is viewed from the front, the presence of the flat plate member 83 is not conspicuous, and the overall aesthetics can be improved. it can.

  As described above, in the roll blind 1 of the present modification, the winding plate storage portion 81A is located at a position where the edge on the free end side of the winding plate 9 is lower than the edge on the screen connection side. Hold in posture. Thereby, since the rib 81Ab on the rear side does not withstand the compressive load and bends, as a result, the storage of the wound plate 9 can be maintained. Note that the above effect can be obtained as long as at least the entire winding plate 9 is held in a horizontal orientation or a forward orientation lower on the front side.

  In this modification, in particular, the winding plate storage portion 81A is positioned higher than the front end rib 81Ac that locks the free end side edge and the edge on the screen connection side higher than the free end side edge. A rear rib 81Ab having a protruding portion 81Ae and a ceiling 81Ad that is curved in a concave shape so as to guide the edge on the free end side to the front rib 81Ac. With such a configuration, even if the operator does not perform a special operation, the winding plate storage portion 81A has a position where the edge on the free end side is lower than the edge on the screen connection side with respect to the winding plate 9. Can be held.

  In the present modification, in particular, the end fixing portion 8A has a flat plate member 83 that is detachable and has a protruding portion 83a that goes upward in the middle of the horizontal direction. The drooping position of the upper end portion of the screen front surface 4a is defined by the edge portion of the horizontal flat plate portion arranged substantially horizontally. Thereby, the flat plate member 83 can be securely fixed to the upper end portion of the screen front surface 4a by placing the protruding portion 83a in contact with the edge portion of the rib 81Ac on the front side, and in the front-rear direction of the screen front surface 4a. The hanging position can be defined easily and reliably. Even when the frame 2A is viewed from the front, the presence of the flat plate member 83 is not conspicuous, so that the overall aesthetics can be improved. Although not particularly illustrated, the L-shaped angle 82 may be locked to the frame 2 so that the L-shaped angle 82 is inserted into the frame 2 from the side. Further, the U-shaped portion that holds the bracket of the frame 2 and the front portion that covers the take-up shaft 3 may be separated if they are positioned and fitted in the front-rear direction. Further, the frame 2 may have a shape that covers only a part of the take-up shaft 3, and the end fixing portion 8 may be supported by the frame 2 that does not cover the take-up shaft 3 and a separate attachment. The end fixing portion 8 may be supported by the bracket 11.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the above-mentioned embodiment and each modification are implemented with various modifications within a range not departing from the gist thereof.
