  In the shielding material mounting device to the winding pipe as described above, when the screen is further lowered after the screen is unwound to the lowest position, the screen is wound in the reverse direction with respect to the winding pipe. However, at this time, since the support member only penetrates between the chins of the screen, the screen is changed to the support member while changing the position of the support member penetrating while maintaining the penetrated state. It becomes possible to move along.

  That is, since the relative position of the support member and the screen changes, as a result, there is a problem that the mounting position of the screen to the winding pipe is shifted.

  When the screen is lifted from this state, the screen wound in the reverse direction is once unwound from the winding pipe and then wound on the winding pipe in the normal direction. However, when the winding is started, the mounting position is changed and remains shifted, and thus there is a problem that the screen is wound while being shifted.

  The present invention has been made in view of the above problems, and can easily attach a shielding material composed of a tree to a winding pipe, and after the shielding material is completely unwound from the winding pipe, the same winding is further performed. It is an object of the present invention to provide a shielding material attaching device to a take-up pipe in which the position where the shielding material is attached to the take-up pipe can be kept unchanged even when the take-up pipe rotates in the solution direction. .

In order to achieve the above-mentioned object, the invention according to claim 1 is characterized in that one end of a shielding material composed of warps in which a plurality of chins are connected in the vertical direction by a weaving thread is supported by both ends rotatably supported. A shield attachment device to a take-up pipe, which is attached to a pipe so as to be wound and unwound,
A fitting part to be attached to the take-up pipe and a bend from one end part of the attachment part to be inserted between the chins at one end part of the shielding material and locked in a groove formed in the take-up pipe And a bent portion that extends further than the bent portion of the bent portion from the mounting portion, and is disposed on the outer diameter side of a part of the shielding material on the other end side from the insertion position of the bent portion. And a projecting piece.

  The mounting portion may be mounted in the groove of the take-up pipe as shown in the cited document 1. However, in the invention according to claim 2, the mounting portion according to claim 1, A part of the shielding material located on one end side from the insertion position of the bent portion is attached to the outer peripheral portion of the winding pipe so as to be sandwiched between the winding pipe and the winding portion.

  According to the first aspect of the present invention, the shielding member is easily attached to the take-up pipe by inserting the bent portion between the chins of the wood and being locked in the groove formed in the take-up pipe. Can do. Furthermore, when the shield pipe is completely unwound from the take-up pipe and the take-up pipe is rotated in the same unwind direction, there is a projecting piece, so that the insertion position is moved toward the mounting part. Therefore, the mounting position of the shielding member and the winding pipe is not changed, and it is possible to prevent the shift from occurring.

  According to the second aspect of the present invention, the mounting part holds the part of the shielding material at one end side with respect to the insertion position of the bent part together with the take-up pipe. It can be restrained and held.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall view of a roll screen 10 in which a shielding material is attached to a winding pipe by a shielding material attaching device to the winding pipe according to the present invention.

  In the figure, the roll screen 10 has a winding pipe 12 and a shielding material 14, and the shielding material 14 is constituted by a warp in which a plurality of chins 15 are connected in the vertical direction by woven yarns 16.

  The winding pipe 12 is rotatably supported by the side plates 18 and 18. Moreover, the operation part 20 which rotates the winding pipe 12 is provided in the one end part of the winding pipe 12, and the winding pipe 12 is rotated in arbitrary directions by operating the operation part 20. Is possible. However, the form of the operation unit 20 can be arbitrary.

  A locking groove 12a (see FIG. 2) is formed in the winding pipe 12 along the longitudinal direction thereof. The locking groove 12a is provided with locking portions 12b and 12b extending from both sides to the groove center side.

  The shielding material attaching device for attaching the shielding material 14 to the take-up pipe 12 includes an attachment piece 24 as shown in FIG. A plurality of attachment pieces 24 may be used by being appropriately separated along the longitudinal direction of the winding pipe 12.

  The mounting piece 24 is made of an arbitrary material made of metal or plastic, preferably an elastic material made of metal, and is roughly bent from the mounting portion 24a and one end portion of the mounting portion 24a, so that the winding pipe 12 A bent portion 24b inserted and locked in the locking groove 12a and a projecting piece portion 24c extending further from the bent portion of the bent portion 24b from the mounting portion 24a are provided.

  The mounting portion 24 a has an arcuate cross-sectional contour similar to a part of the outer shape of the winding pipe 12 so as to be mounted on the outer peripheral portion of the winding pipe 12. The bent portion 24b is bent in two stages from the mounting portion 24a. The first bent portion 24b1 and the first bent portion 24b1 are bent in the inner diameter direction at approximately 90 degrees from the mounting portion 24a. And the second bent portion 24b2 which is folded back at about 90 degrees. A pair of bent portions 24b are provided on both sides of the mounting portion 24a in the width direction. The protruding piece 24c is formed to extend as an extension of the mounting portion 24a from between the pair of bent portions 24b.

  When the mounting piece 24 is made of metal, it can be easily manufactured by bending a single metal plate.

  In order to attach the shielding member 14 to the take-up pipe 12 using the mounting piece 24 described above, a bent portion 24b is inserted between any adjacent chins 15 and 15 located slightly lower than the upper end of the shielding member 14. Insert through. And the bending part 24b is inserted in the locking groove 12a of the winding pipe 12, and the front-end | tip is locked to the locking part 12b of the locking groove 12a. At the same time, the mounting portion 24 a is mounted on the outer peripheral portion of the winding pipe 12, and the attachment piece 24 is fitted to the outer peripheral portion of the winding pipe 12 by the elasticity of the mounting portion 24 a. Thus, the mounting piece 24 is fixed to the take-up pipe 12, and the shielding member 14 is inserted into the bent portion 24b of the mounting piece 24. The tip of the bent portion 24b is in the locking groove 12a and is a free end. Therefore, the shielding member 14 is attached to the winding pipe 12 via the attachment piece 24 (see FIG. 3A). The mounting portion 24 a is disposed on the outer diameter side of the upper end portion of the shielding member 14 from the insertion position of the bent portion 24 b, and sandwiches the upper end portion together with the winding pipe 12. In addition, the projecting piece 24c is arranged on the outer diameter side of the lower end side of the insertion position of the bent portion 24b of the shielding material 14.

  When the winding pipe 12 is rotated, the shielding member 14 attached as described above is wound up or down in order to be wound around the winding pipe 12 or to be unwound from the winding pipe 12 according to the rotation direction. It can be carried out. At this time, the mounting portion 24a is fitted to the outer peripheral portion of the take-up pipe 12, and the outer shape thereof is substantially the same as a part of the outer shape of the take-up pipe 12, so that the attachment piece 24 becomes an obstacle. Instead, the shielding member 14 is wound on the mounting piece 24 (see FIG. 3B). Note that the winding direction of the regular winding pipe 12 is the winding pipe from the state in which the shielding member 14 is mounted to the winding pipe 12 with the mounting portion 24a side of the mounting piece 24 as the head and the protruding piece portion 24c side as the tail. 3 turns counterclockwise in FIG. 3, and the winding direction of the normal winding pipe 12 is that the winding pipe 12 rotates with the opposite mounting portion 24a side as the rear and the projecting piece portion 24c side as the head. 3 in the clockwise direction.

  When the shielding material 14 is completely unwound from the winding pipe 12 and the winding pipe 12 is further rotated in the same unwinding direction, the shielding material 14 is wound in the reverse direction with respect to the winding pipe 12. However, since the winding pipe 12 rotates with the projecting piece 24c as the head, the shielding material 14 is folded and wound up at the tip of the projecting piece 24c (FIG. 3C). reference). For this reason, the relative movement with respect to the attachment piece 24 is prohibited and the insertion position of the shielding member 14 does not move due to the presence of the protruding piece portion 24c. Therefore, the displacement of the mounting position of the shielding material 14 from the winding pipe 12 does not occur.

  On the other hand, if there is no projecting piece 24c, as shown in FIG. 4, when the shielding material 14 is wound up in the opposite direction with respect to the take-up pipe 12, the mounting piece 24 becomes the shielding material. 14 is caused to move relative to the mounting piece 24 while the insertion position for inserting 14 moves from the bent portion 24b toward the mounting portion 24a (FIG. 4B). 14 and the take-up pipe 12 are displaced from each other, and if the operation is further continued, the shielding material 14 falls from the take-up pipe 12. For example, when the take-up pipe 12 is rotated in the normal take-up direction from the state as shown in FIG. 4B, the take-up position is taken off and the subsequent operation is performed. The height dimension of 14 will also go crazy.

  In the present embodiment, since there is the projecting piece portion 24c, such a shift of the mounting position does not occur, and the correct mounting position of the shielding material 14 can always be maintained.

  Further, in this embodiment, the mounting portion 24a holds the upper end portion of the shielding member 14 together with the winding pipe 12 from the insertion position of the bent portion 24b of the shielding member 14, and reliably restrains the upper end portion of the shielding member 14. Can be held.
