The thickness of the first sound absorbing plate 31 and the second sound absorbing plate 34 is equal to the outer diameter of the first and second vertical frame portions 21 and 22 and is thicker than the thickness of the first to third horizontal frame portions 23 to 25 in the front-rear direction.

  The frame member 20, the first sound absorbing plate 31, and the second sound absorbing plate in a state where the first sound absorbing plate 31 and the second sound absorbing plate 34 are fitted in the first region 26 and the second region 27 of the frame member 20, respectively. 34 is covered with a cover member 40.

  As shown in FIG. 7, the cover member 40 includes a cover main body 41 whose upper and left and right sides are closed and whose lower side is opened, and connection portions 42 provided on the left and right sides of the cover main body 41. .

  The cover main body 41 is formed by forming a polyester fiber cloth into a bag shape, the upper side is closed, and the lower side is provided with an opening. The length of one round of the inner circumference in the plane parallel to the floor surface of the cover body 41 is equal to the length of one round of the outer circumference in the plane parallel to the floor surface of the frame member 20. That is, the length of the inner circumference of the cover main body 41 is equal to twice the length between the central axes of the first vertical frame portion 21 and the second vertical frame portion 22 plus the circumference of the first vertical frame portion 21. Is equal to

  The connection portion 42 is formed of a polyester fiber cloth like the cover body 41, and a front member 42a and a rear member 42b having the same shape are stitched and joined. The connecting portion 42 includes four bar magnets 43 on both the left and right sides. These bar magnets 43 have the same shape and are provided at equal intervals in the vertical direction. The bar magnet 43 has a cylindrical shape and is provided such that the longitudinal direction is the vertical direction. As shown in the end views of FIGS. 8 to 10, the bar magnet 43 is sandwiched and fixed between the front member 42a and the rear member 42b. Specifically, the front side member 42a and the rear side member 42b have the widthwise outer end portions 44a and 44b stitched together and the widthwise inner end portions 45a and 45b stitched together. With this configuration, the position in the width direction of the connecting portion 42 of the bar magnet 43 is held between the outer end portions 44a and 44b and the inner end portions 45a and 45b. Further, in the connecting portion 42, the end portions of the bar magnet 43 in the vertical direction are also sewn together. With this configuration, the vertical position of the bar magnet 43 is fixed.

  The polarity of the bar magnet 43 is N pole on the upper side in one connecting portion 42, and is S pole on the upper side in the other connecting portion 42. The positions of the bar magnets 43 in the vertical direction are the same in the one connection portion 42 and the other connection portion 42.

  Buttons 44 are provided in the vicinity of the upper end portion of the connection portion 42 and in the vicinity of the lower end portion thereof. The button 44 is, for example, a jumper hook button made of metal. The button 44 is provided on both the front member and the rear side, the button 44 of the front member 42a has a convex shape, and the button 44 of the rear member 42b has a concave shape. The button 44 is provided outside the position where the bar magnet 43 is provided in the lateral direction.

  The cover member 40 configured as described above is placed on the frame member 20, the first sound absorbing plate 31, and the second sound absorbing plate 34 from above, so that the partition 10 shown in FIGS. 1 and 11 is configured. . Since the inner dimensions of the cover main body 41 of the cover member 40 are determined as described above, the inner surfaces of the left and right sides of the cover member 40 are the first vertical frame portions as shown in the end views of FIGS. 21, abuts on the outer peripheral surface of the second vertical frame portion 22, and the front and back inner surfaces of the cover member 40 abut on the entire front surface and the entire rear surface of the first sound absorbing plate 31 and the second sound absorbing plate 34. Moreover, since the thickness of the 1st, 2nd sound-absorbing plates 31 and 34 is thicker than the thickness of the 1st-3rd horizontal frame parts 23-25, it is between the 1st-3rd horizontal frame parts 23-25 and the cover member 40. Produces voids.

  The left and right positions of the first sound absorbing plate 31 and the second sound absorbing plate 34 are fixed by the first and second vertical frame portions 21 and 22, and the vertical position of the first sound absorbing plate 31 is the first and second horizontal frames. The positions of the second sound absorbing plate 34 in the vertical direction are fixed by the second and third horizontal frame portions 24 and 25. The positions of the first and second sound absorbing plates 31 and 34 in the front-rear direction (thickness direction) are fixed by the inner surface of the cover main body 41 of the cover member 40.

  Next, the case where the partitions 10 described above are connected will be described with reference to FIG. The partitions 10 are connected to each other by bringing the connecting portions 42 into contact with each other. Specifically, the connection part 42 in which the south pole of the bar magnet 43 is on the upper side and the connection part 42 in which the north pole of the bar magnet 43 is on the upper side are brought into contact with each other. By doing so, the S pole side and the N pole side of the bar magnet 43 attract each other, and the connection portions 42 are connected to each other.

  At this time, since the bar magnet 43 is provided apart from both ends in the width direction of the connection portion 42, the connection portion 42 bends at the inner end portions 45 a and 45 b where the bar magnet 43 is not provided. Thereby, when connecting the connection parts 42, the fine position adjustment of the partition 10 itself becomes unnecessary, and the connection parts 42 can be easily connected.

  When connecting the connection parts 42, the connection by the button 44 provided in the connection part 42 is also performed. As described above, the convex button 44 is attached to the front member 42a of the connecting portion 42, and the concave button 44 is attached to the rear member 42b. Therefore, the button 44 is engaged by bringing the front member 42a of the connecting portion 42 of the one partition 10 into contact with the rear member 42b of the connecting portion 42 of the other partition 10. By doing so, the connection by the magnetic force of the bar magnet 43 and the connection by the engagement of the button 44 are performed, and the partitions 10 can be connected more reliably.

  When the partitions 10 are connected to each other as shown in FIG. 15, the connecting portion 42 opposite to the connected side may be bent inward and magnetically attached to the steel frame member 20.

  With the above configuration, the partition 10 according to the present embodiment has the following effects.

  The skeleton of the partition 10 is formed by the frame member 20, and the sound absorbing plates 31 and 34 are disposed in the regions 26 and 27 surrounded by the vertical frame portions 21 and 22 and the horizontal frame portions 23 to 25 of the frame member 20. The sound absorbing plates 31 and 34 are covered by the cover member 40 together with the frame member 20, and the cover member 40 is prevented from dropping from the regions 26 and 27 in the front-rear direction. As a result, the sound absorbing plates 31 and 34 can be held by simply placing them in the regions 26 and 27 and covering the cover member 40, and the partition 10 that exhibits a soundproofing effect can be provided with a simple configuration.

  In particular, when the sound absorbing plates 31 and 34 are provided on articles placed indoors, since the sound absorbing plates 31 and 34 are poor in design, generally, a decorative material or the like is bonded to the surface of the sound absorbing plates 31 and 34. . In this case, since a flammable adhesive is used for bonding a decorative material or the like, the fireproof performance is lowered. In this respect, in the present embodiment, since the sound absorbing plates 31 and 34 are covered with the cover member 40, it is not necessary to adhere a decorative material or the like to the surfaces of the sound absorbing plates 31 and 34, and a flammable adhesive becomes unnecessary. Therefore, the fireproof performance of the partition 10 as a whole can be improved.

  If a decorative material or the like is bonded to the surfaces of the sound absorbing plates 31 and 34 with an adhesive, an adhesive layer is formed on at least a part of the surfaces of the sound absorbing plates 31 and 34. In this case, the sound absorption performance of the entire sound absorbing plates 31 and 34 is deteriorated because the adhesive layer prevents the sound from entering the sound absorbing plates 31 and 34. In this respect, in the present embodiment, since the sound absorbing plates 31 and 34 are covered with the cover member 40, no adhesive layer is formed on the surfaces of the sound absorbing plates 31 and 34, and sound is incident on the sound absorbing plates 31 and 34. I can't interfere. Therefore, the sound absorption performance of the entire partition 10 can be improved.

  When the first and second sound absorbing plates 31 and 34 are disposed in the first and second regions 26 and 27, they are fitted between the first and second vertical frame portions 21 and 22 and between the first to third horizontal frame portions 23 to 25. Become a shape. Therefore, the first and second sound absorbing plates 31 and 34 can be temporarily fixed to the first and second regions 26 and 27 before the cover member 40 is attached, and the workability when covering with the cover member 40 is improved. When the first and second sound absorbing plates 31 and 34 are fitted between the first and second vertical frame portions 21 and 22 and between the first to third horizontal frame portions 23 to 25, the inside of the frame member 20 This space can be filled with the first and second sound absorbing plates 31 and 34, so that it is difficult to generate a partitioning space only with the cover member 40.

  -Since the inner surface of the cover member 40 is in contact with the surfaces of the sound absorbing plates 31 and 34, the sound absorbing plates 31 and 34 can be easily positioned in the regions 26 and 27, and rattling of the sound absorbing plates 31 and 34 is suppressed. can do.

  -Since the glass wool which has elasticity is employ | adopted as the sound-absorbing plates 31 and 34, the error of the dimension in manufacturing can be absorbed.

  -Since the cover member 40 is made into the bag shape which the upper part obstruct | occluded, the frame member 20 and the sound-absorbing plates 31 and 34 can be covered only by covering from the upper direction of the frame member 20. FIG.

  -Since the connection part 42 is provided in the both ends of the width direction of the partition 10, the several partition 10 can be used in combination.

Second Embodiment
In the present embodiment, the shape of the frame member 20 is the same as that of the first embodiment. On the other hand, as shown in FIG. 16, the thickness of the first sound absorbing plate 131 is made larger than the diameters of the first and second vertical frame portions 21 and 22 of the frame member 20. Although the second sound absorbing plate has the same thickness as the first sound absorbing plate 131, the end view at the position including the second sound absorbing plate is the same as the AA end view and the EE end view. Illustration and description are omitted.

  As shown in the end views of FIGS. 17 and 18, the cover member 140 includes a cover body 141 that is closed on both the upper and left and right sides and opened on the lower side, and the left and right sides of the cover body 141, as in the first embodiment. And connecting portions 142 provided on both sides.

  The cover main body 141 is formed by forming a polyester fiber cloth into a bag shape. The length of the inner circumference of the surface parallel to the floor surface of the cover main body 141 is larger than the length of the outer circumference of the surface of the frame member 20 parallel to the floor surface, and the first sound absorbing plate is attached to the frame member 20. It is smaller than the outer shape when 131 is fitted. More specifically, the length of the inner circumference of the cover body 41 is twice the length between the central axes of the first vertical frame portion 21 and the second vertical frame portion 22. 2 times the circumference of the first vertical frame 21 is added to twice the length between the central axes of the first vertical frame 21 and the second vertical frame 22 and larger than the sum of the circumferences. Smaller than

A bar magnet 143 is provided between the front member 142a and the rear member 142b. The front side member 142a and the rear side member 142b have the widthwise outer ends 144a and 144b sewn together, and the widthwise inner ends 145a and 145b stitched together. With this configuration, the position in the width direction of the connecting portion 142 of the bar magnet 143 is held between the outer end portions 144a and 144b and the inner end portions 145a and 145b. The connection unit 142 also includes a button (not shown) similar to that in the first embodiment.

  Since the shape of the cover member 140 is determined in this way, the first sound absorbing plate 131 and the second sound absorbing plate (not shown) are fitted into the frame member 20, and as shown in the end views of FIGS. 17 and 18. When covered with the cover member 140, the inside of the cover member 140 contacts the first and second vertical frame portions 21 and 22 and also contacts the sound absorbing plate 131. At this time, the sound absorbing plate 131 is elastically deformed by being pressed from the front-rear direction and contracting in the front-rear direction (thickness direction). On the other hand, the inner surface of the cover member 140 receives a pressing force from the sound absorbing plate 131, and tension due to the pressing force is constantly generated.

  With the above configuration, the partition 10 according to the present embodiment has the following effects in addition to the effects exhibited by the partition 10 according to the first embodiment.

  The sound absorbing plate 131 is formed on the frame member 20 because it is thicker than the outer diameter of the first and second vertical frame portions 21 and 22 and the thickness of the first to third horizontal frame portions 23 to 25. When the sound absorbing plate 131 is fitted in the region and the cover member 140 is covered, the sound absorbing plate 131 is sandwiched by the cover member 140 from the front and rear directions and elastically deformed. In this case, the sound absorbing plate 131 is pressed against the cover member 140 from the inside so as to return to the original shape. Therefore, the holding force of the cover member 140 with respect to the sound absorbing plate 131 can be improved, and the frame member 20 and the cover member 140 can be covered without causing wrinkles on the surface of the cover member 140.
