The sound absorbing material 12 is filled, and the sound insulation around the advance / retreat mechanism 28 is high.

  Next, the closing members 6 and 7 will be described. As shown in FIG. 4, the closing member 6 provided on the upper portion of the partition panel 2 has a U-shaped casing 34 and a plurality of communication holes 35 a, 35 a,. It is mainly composed of the fine perforated plate 35 and the sound absorbing material 12. On the front and rear edges of the bottom portion 341 of the housing 34, projection pieces 36, 36 continuous in the longitudinal direction of the housing 34 are attached so as to project obliquely outward. The projecting pieces 36 are formed of an elastic member such as rubber. In addition, the housing 34 is filled with the sound absorbing material 12. The sound absorbing material 12 is continuous without being divided in the longitudinal direction of the housing 34.

  Overhangs 38, 38 are provided at the ends of the sides 34, 342 of the housing 34 on the opening side of the housing 34, and the upper portions of the overhangs 38, 38 are along the longitudinal direction. Fitting grooves 38a, 38a are formed. A packing 39, which is an elastic material such as rubber, is fitted in the fitting grooves 38 a and 38 a so that a head 39 a (protruding piece) of the packing 39 is exposed to the outside. 39a is flush with the ceiling surface R and functions as a cushioning material that comes into contact with the lower surface 4a (see FIG. 8) of the rail 4 that constitutes the ceiling surface R together.

  Further, projecting portions 40, 40 projecting inward from both side portions 342, 342 of the housing 34 are formed below the projecting portions 38, 38, and the bottom surfaces 38b, 38b of the projecting portions 38, 38 and the projecting portions are formed. The fine perforated plate 35 is fitted into the groove portions 40a, 40a formed by 40, 40. As described above, since the opening of the housing 34 is closed by the fine perforated plate 35, the inside of the housing 34 is formed through the communication holes 35 a, 35 a,. The filled sound absorbing material 12 is exposed to the outside. Note that the number of communication holes is not limited to a plurality, and may be one, and the shape of each communication hole may be circular or elliptical, or may be a slit shape.

  As shown in FIG. 4, long holes 341a and 341a are formed in the bottom portion 341 of the housing 34 along the longitudinal direction, and the micro perforated plate 35 is substantially the same as the long holes 341a and 341a. Shaped long holes 35b, 35b are formed. Further, the sound absorbing material 12 is formed with through holes 37 and 37 that communicate the long holes 341a and 341a and the long holes 35b and 35b in the vertical direction. As shown in FIGS. 1 and 6, the long holes 341a and 341a, the long holes 35b and 35b, and the through holes 37 and 37 communicate with each other at the time of assembly. The long holes 341a and 341a and the long holes 35b and 35b The closing member 6 is fitted into the upper channel portion 19 in a state where the suspension support members 23 are inserted into the through holes 37. Since these long holes 341a and 341a, the long holes 35b and 35b, and the through holes 37 and 37 have a long hole shape in the width direction of the partition panel 2, even if the closing member 6 rotates as described later, The housing 34, the fine perforated plate 35, and the sound absorbing material 12 in the housing 34 are prevented from interfering with the suspension members 23 and 23.

  In addition, the closing member 7 provided in the lower part of the partition panel 2 has basically the same shape as the closing member 6, and is not particularly shown. However, the suspension member 23 is provided on the closing member 7 side, that is, on the lower part of the partition panel 2. , 23 are not provided, the closing member 7 does not have the configuration of the long holes 341a, 341a, the long holes 35b, 35b and the through holes 37, 37 described above.

  As shown in FIG. 5, in the upper channel portion 19 and the lower channel portion 20, advance / retreat mechanisms 28, 28,. Since the advancing / retreating mechanism 28 for the closing member 6 and the advancing / retreating mechanism 28 for the closing member 7 use the advancing / retreating mechanism 28 having the same configuration and the same dimensions (same shape members) that are vertically symmetrical, the closing member 6 is used here. The advance / retreat mechanism 28 will be described.

  The advance / retreat mechanism 28 mainly includes a link member 29, an upper end member 41, a lower end member 42, and a torsion coil spring 33. The upper end member 41 is fixed to the bottom portion 341 of the casing 34 of the closing member 6, and the lower end member 42 is fixed to the bottom surface portion 191 a of the upper opening member 191. A long hole 31 facing the longitudinal direction of the link member 29 is formed on one side of the link member 29, and a pin 32 provided on the lower end member 42 is loosely fitted in the long hole 31. The other end of the link member 29 is pivotally attached to the upper end member 41 by a shaft 30. The upper end member 41 is provided with a shaft portion 50, and a torsion coil spring 33 as a biasing means for biasing the shaft portion 50 and the pin 32 so as to be separated from each other is stretched. .

As shown in FIGS. 1 and 5A, when the closing member 6 is stored in the advance / retreat mechanism 28,
Since the torsion coil spring 33 urges the shaft portion 50 and the pin 32 to be separated from each other, the closing member 6 is accommodated in the upper channel portion 19 while the closing member 6 moves in the left-right direction with respect to the panel body 5. Will be.

  When the left end of the closing member 6 comes into contact with the preceding partition panel 2 and is moved to the right side of the screen from the state of FIG. 5A, as shown in FIG. Since it comes up while rotating against the urging force of the torsion coil spring 33, it acts to push up the closing member 6. Although not shown, when the lower end of the closing member 7 is moved in contact with the preceding partition panel 2, the link member 29 rises and pushes down the closing member 7 in the same manner as the advance / retreat mechanism 28 for the closing member 6. Acts as follows.

  When the closing member 6 is pushed up by the advancing and retracting mechanisms 28, 28,... And the closing member 7 is pushed down, the upper end of the closing member 6 is urged by the biasing force of the torsion coil spring 33 as shown in FIGS. The head portion 39a of the packing 39 positioned at the bottom is pressed against the ceiling surface R, and the head portion 39a of the packing 39 positioned at the lower end of the closing member 7 is pressed against the floor surface F. After the closing member 6 and the closing member 7 are in contact with the ceiling surface R and the floor surface F and their extension stops, the pin 32 moves relative to the inside of the long hole 31 to cause the shaft portion 50 to move to the pin 32. The link member 29 is rotated until it passes directly above, that is, exceeds the dead point.

  As shown in FIG. 7, the distance α between the upper edge 6 a of the closing member 6 and the fixing position of the upper end member 41 and the closing member 6 in the advance / retreat mechanism 28 is such that the backing material 11 of the panel material 51 has a distance α. It is designed to be larger than the distance β between the upper edge 11a and the ceiling surface R. Therefore, when the closing member 6 is extended, the upper end member 41 in the advance / retreat mechanism 28, that is, the upper end of the advance / retreat mechanism 28 is located in the upper channel portion 19 surrounded by the backing materials 11, 11. Only a part of the closing member 6 filled with the sound absorbing material 12 extends from the main body 5.

  As described above, each of the advance / retreat mechanisms 28, 28,... Has an upper channel portion 19 located between the backing members 11 and 11 having a predetermined thickness when the closing members 6 and 7 are extended and stored. And since it will always be located in the lower channel part 20, sound insulation property is high also in the periphery of the advancing / retreating mechanism 28 where the sound absorbing material 12 is not filled.

  As described above, each advancing / retracting mechanism 28 is always disposed in the upper channel portion 19 and the lower channel portion 20 with high sound insulation in the partition panel 2, and the protruding portions of the closing member 6 and the closing member 7. Since the sound-insulating effect is enhanced by the sound-absorbing material 12 continuously filled in the longitudinal direction of the casing 34, the sound can be reliably insulated by the protruding portion and the panel body 5. In other words, sound leakage between the sections partitioned by the partition panel 2 can be reliably prevented by the entire partition panel 2.

  Further, as shown in FIG. 8, in the state where the closing member 6 and the closing member 7 are extended, the heads of the front and rear packings 39 and 39 are transmitted by passing through the heads 39a and 39a of the front and rear packings 39 and 39, for example. Part of the sound that has entered the space 43 between the portions 39a and 39a is absorbed by the sound absorbing material 12 through the communication holes 35a, 35a,... Of the fine perforated plate 35, so that the volume can be reliably reduced. it can. Further, since the sound that has entered the space 43 reaches the sound absorbing material 12 that continues along the housing 34 through the communication holes 35a, 35a,..., The sound that the sound absorbing material 12 has entered the space 43 is ensured. Sound leakage can be reliably reduced by absorbing sound.

  Further, the advancing / retreating mechanisms 28, 28,... Operate so that the closing members 6 and 7 extend when the left ends of the closing members 6 and 7 come into contact with the preceding partition panel 2. For example, it is not necessary to provide special operating means for operating the advance / retreat mechanisms 28, 28,... By operating from the outside, and the space required for the operation of the advance / retreat mechanisms 28, 28,. Therefore, since the sound absorbing material 12 can be filled in a larger range around the advance / retreat mechanisms 28, 28,... In the upper channel portion 19 and the lower channel portion 20, the sound insulation performance around the advance / retreat mechanism 28 can be improved. .

  The advancing / retreating mechanism 28 is not limited to a mode in which one end member 41 is fixed to the bottom 341 of the casing 34 in the closing members 6 and 7. For example, as shown in FIG. 9, the closing member 61 includes the erection bodies 44, 44 in which the side portions 342, 342 of the casing 34 ′ are arranged at the center portions of the side portions 342, 342 instead of the bottom portion. The upper end member 41 in the advance / retreat mechanism 28 is fixed to the erected body 44.

  Even in such a case, the distance between the upper edge 6a of the closing member 6 and the installation bodies 44, 44 (that is, the upper edge 6a of the closing member 6 and the upper end member 41 and the closing member 6 in the advance / retreat mechanism 28). Since the distance α) to the fixed position is designed to be larger than the distance β between the upper edge 11a of the backing material 11 and the ceiling surface R in the panel material 51, the closing member 6 is extended. The upper end member 41 in the advance / retreat mechanism 28, that is, the upper end of the advance / retreat mechanism 28 is positioned in the upper channel portion 19 surrounded by the backing materials 11, 11, and the sound absorbing material 12 is received from the panel body 5. Only a part of the filled blocking member 6 extends.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above-described embodiment, the sound absorbing material 12 filled in the housing 34 is exposed to the outside through the communication holes 35a, 35a,... For example, the sound absorbing material 12 may be exposed to the outside across the opening of the housing 34 without particularly providing a fine perforated plate.

  In the embodiment, the lower end members 42 and 42 of each advance / retreat mechanism 28 are fixed to the bottom surface portion 191 a of the upper opening member 191 and the bottom surface portion 201 a of the lower opening member 201. Is not limited to this mode as long as it is within the channel portion. For example, the lower end members 42 and 42 of each advance / retreat mechanism 28 are fixed to the side surface portion 191b and the side surface portion 201b of the upper opening member 191 and the lower opening member 201. Also good.

  Moreover, although the upper end of the advancing / retreating mechanism 28 was positioned in the upper channel portion 19 surrounded by the backing materials 11 and 11 when the closing member 6 was extended, for example, the panel material is high. If the upper end of the advancing / retreating mechanism is disposed inside the panel material, the upper end of the advancing / retreating mechanism is not necessarily disposed inside the backing material in the channel portion. Not exclusively.

  In the above-described embodiment, the description has been made assuming that two advance / retreat mechanisms 28 are provided in each of the upper channel portion 19 and the lower channel portion 20. As long as it can be extended while maintaining the horizontal state of 7, the number arranged in the upper channel portion 19 and the lower channel portion 20 may be one each, or a plurality of three or more may be provided. Good.

  In addition, the sound absorbing material 12 is filled between the front and rear backing materials 11, 11, but is not limited thereto. For example, the backing material has a honeycomb structure, and the honeycomb structure is filled with the sound absorbing material. Also good. Thereby, the panel material can be reduced in weight while having sound insulation properties.

  Moreover, although the upper-side closing member 6 and the lower-side closing member 7 have the same dimensions, the present invention is not limited thereto, and may be designed in different shapes.
