The screw holes 31d are connected by screwing.

  For this reason, the slide rail 33 can expand and contract in the vertical direction. That is, when the slide rail 33 shown in FIGS. 3 to 5 is contracted and the inner rail 32b is slid and raised with respect to the outer rail 32a, the state shown in FIGS. 7 and 8 is obtained. From this state, when the inner rail 32b is further pulled upward to rise, the outer rail 32a rises together with the inner rail 32b, and the inner rail 31b is pulled upward by the rise of the outer rail 32a. Therefore, the inner rail 31b rises while sliding with respect to the outer rail 31a, and the slide rail 33 is in an extended state as shown in FIGS. Thus, the slide rail 33 extends over two stages.

  Moreover, the slide rail 33 can be contracted from the extended state by the reverse operation. That is, when the inner rail 32b is slid and lowered with respect to the outer rail 32a from the state shown in FIGS. 9 to 11, the state shown in FIGS. 12 and 13 is obtained, and further, the inner rail with respect to the outer rail 31a.

The support shaft 34c is slightly longer than the left and right widths of the rail support portion 21b of the base portion 21, and is configured by a shaft body that can be inserted into the insertion hole of the bearing portion 21e. It protrudes and is inserted through the insertion holes of the pair of bearing portions 21e. The rail pulleys 34a and 34b are rotatably supported at both ends of the support shaft 34c and are positioned on both sides of the rail support portion 21b.

  The lower pulley assembly 35 includes a small pair of rail pulleys 35a and 35b, assembly pieces 35c and 35d, a short shaft portion 35e that rotatably attaches the rail pulley 35a to the assembly piece 35c, and a rail pulley 35b that is an assembly piece 35d. It is comprised with the short shaft part 35f assembled | attached rotatably. The assembling piece 35c and the assembling piece 35d are formed of a plate-like member having a projecting portion and a recessed portion that can be fitted to each other, and are combined to form a substantially rectangular shape along the lower portion of the rear surface of the outer rail 32a. It is formed in the shape of a plate.

  Also, from the lower ends of the outer portions of the assembly pieces 35c, 35d, support pieces 35g each provided with an insertion hole protrude rearward with a sufficient space between the both sides of the inner rail 31b. The rail pulley 35a is rotatably assembled to the assembly piece 35c through the insertion hole of the short shaft portion 35e and one support piece 35g, and the rail pulley 35b is inserted into the insertion hole of the short shaft portion 35f and the other support piece 35g. It is assembled | attached rotatably to the assembly | attachment piece 35d via. In addition, screw insertion holes 35h are formed above and below the assembled pieces 35c and 35d in the assembled state.

  The short shaft portions 35e and 35f are inserted through the insertion holes of the support piece 35g from the inside to the outside, respectively, and the inner end portions are crimped. Next, the rail pulleys 35a and 35b are assembled to the assembly pieces 35c and 35d by passing the outer portions of the short shaft portions 35e and 35f through the center holes of the rail pulleys 35a and 35b and engaging the E-rings with the ends. . In order to facilitate the caulking process at this time, assembly pieces 35c and 35d made of two members are used. Therefore, the assembly pieces 35c and 35d may be integrally formed if there is no problem in manufacturing. The E-ring is also engaged with both ends of the support shaft 34c of the base side pulley 34 described above. In this case, since the support shaft 34c is composed of one long shaft, the rail pulleys 34a, 34b Is easy to assemble.

  The lower pulley assembly 35 configured as described above has the above-described outer rail 32a and the above-described outer rail 32a in a state where the assembly pieces 35c and 35d are positioned between the lower rear surface of the outer rail 32a and the lower front surface of the inner rail 31b. Of the three screws for fixing the inner rail 31b, the screws are fixed by two screws for fixing the center and lower part of the outer rail 32a and the inner rail 31b.

When contracted, it is located between the lower ends of the outer rails 31a and 32a as shown in FIGS. 3 (a) and 3 (b). For this reason, when the slide rail 33 expands and contracts, the rail pulleys 35a and 35b do not become an obstacle.

  That is, the shaft portion connecting the rail pulleys 35a and 35b is not formed by one shaft portion but by two short shaft portions 35e and 35f, so that the inner rail 31b is positioned between the short shaft portions 35e and 35f. The rail pulleys 35a and 35b can be arranged on both sides of the lower end of the inner rail 31b. Accordingly, it is possible to prevent the short shaft portions 35e and 35f from projecting downward from the lower end of the inner rail 31b and increasing the length of the entire movable decorative device 20 in the vertical direction.

  The upper pulley assembly 36 includes a pair of small rail pulleys 36a and 36b, a support shaft 36c that rotatably supports the rail pulleys 36a and 36b, and an assembly piece 36d that has a U-shaped cross section for supporting the support shaft 36c. The screw insertion hole 36e is formed in the lower side portion at the center in the width direction. Further, insertion holes are respectively formed on the upper ends of both side portions of the assembly piece 36d, and the support shaft 36c is inserted through the insertion hole. The rail pulleys 36a and 36b are rotatably assembled to both ends of a support shaft 36c protruding from both side portions of the assembly piece 36d. The E-ring is engaged with both ends of the support shaft 36c. In this case, the support shaft 36c is composed of one long shaft, so that the rail pulleys 36a and 36b can be easily assembled. The assembly piece 36d is formed of an integral member.

  The upper pulley assembly 36 configured in this manner covers the upper portion of the outer rail 32a from the rear, and the assembly piece 36d is positioned between the rear upper portion of the outer rail 32a and the front upper portion of the inner rail 31b. Of the three screws for fixing the outer rail 32a and the inner rail 31b described above, the upper portions of the outer rail 32a and the inner rail 31b are fixed by one screw. In this case, the upper portion of the assembly piece 36d protrudes upward from the upper ends of the outer rail 32a and the inner rail 31b, whereby the rail pulleys 36a and 36b and the support shaft 36c are also formed between the outer rail 32a and the inner rail 31b. It is located above the upper end.

  Further, the rail pulleys 36a and 36b and the support shaft 36c are arranged at positions where they do not come into contact with the inner rail 32b even if the inner rail 32b slides relative to the outer rail 32a. For this reason, when the slide rail 33 expands and contracts, the rail pulleys 36a and 36b do not become an obstacle. When the slide rail 33 contracts, the rail pulleys 36a and 36b are positioned above the slide rail 33 and not in contact with the slide rail 33, as shown in FIGS. 3B and 3C. .

  The elongated yarn member 37 is made of a yarn made of natural fiber, nylon, or glass fiber. As shown in FIGS. 14A and 14B, the rail pulley 34a disposed on the left side of the slide rail 33, 35a and 36a. In other words, the elongated yarn member 37 is lifted from below and hung over the upper portion of the rail pulley 34a, then lowered, hung over the lower portion of the rail pulley 35a, and raised again to be hung over the upper portion of the rail pulley 36a. And the front-end | tip part of the extending | stretching thread member 37 descend | falls and is connected with the lower part (in fact, the lower part of the attachment board 27 mentioned later) of the inner rail 32b.

  Further, as shown in FIGS. 5, 8, 11, and 13, the base end side portion of the elongated yarn member 37 is a portion from the left side (right side in FIGS. 5, 8, 11, and 13) to the lower part of the direction change pulley 24. After being stretched, the end is connected to the motor pulley 23. In this case, the proximal end side portion of the elongated yarn member 37 extends so as to be stretched over the lower portion of the motor pulley 23, whereby the proximal end side portion of the elongated yarn member 37 is connected to the motor pulley 23 and the direction changing pulley 24. It extends in the left-right direction on the lower side.

  Because of this configuration, when the motor 22 is operated from the state of FIG. 14A and the motor pulley 23 is rotated in one direction (clockwise in the state of FIGS. The base end portion of the member 37 is wound around the motor pulley 23, and the portions of the stretched yarn member 37 that are stretched between the rail pulley 34a and the rail pulley 35a, the rail pulley 36a, and the lower portion of the inner rail 32b are shortened. . As a result, the inner rail 32b slides with respect to the outer rail 32a, and the inner rail 31b slides with respect to the outer rail 31a to be in the state shown in FIG. When the slide rail 33 contracts from the state shown in FIG. 14B and returns to the state shown in FIG. 14A, the proximal end portion of the elongated yarn member 37 is fed out from the motor pulley 23.
