It is the elements on larger scale which show the state which attached the channel | path shielding member. It is an expanded sectional view of the principal part.

  Embodiments of the present invention will be described below. In the following embodiments, the passage shielding member is described as an elastically deformable sheet, but a frame-shaped door may be used as the passage shielding member.

  FIG. 1 is an overall perspective view showing an embodiment of the present invention. 1 is a rack row in which a plurality of racks 2 of the same size are arranged in a row. These rack rows 1 are arranged opposite to each other with a space that allows people to pass between them. As will be described below, this space is closed by the floor, the ceiling shielding member 4, and the passage shielding member 5, and cooling air is supplied into the interior from the floor surface. In FIG. 1, three racks 2 are illustrated as the rack row 1, but in reality, the rack row 1 is often constituted by a larger number of racks 2.

  As shown in FIG. 2, a ceiling rail 3 is provided on the ceiling of each rack 2, and a ceiling shielding member 4 is placed on the ceiling rails 3 on both sides as shown in FIG. ing. As described above, in the event of an earthquake, the rack row 1 may swing differently for each row, and if the both ends of the ceiling shielding member 4 are firmly fixed to the ceiling rails 3 on both sides, the rack row 1 is destroyed. There is. Therefore, in the present invention, the ceiling shielding member 4 is supported on at least one upper surface of the ceiling rail 3 so as to absorb vibration. That is, one side of the ceiling shielding member 4 is fixed to the ceiling rail 3, and the opposite side is simply supported on the upper surface of the ceiling rail 3, or both sides are not fixed and only the end portion is prevented from coming off. In the latter case, it is preferable that the contact surface between the ceiling shielding member 4 and the ceiling rail 3 is an inclined surface and is always located in the center by its own weight. In this way, if the ceiling shielding member 4 can absorb vibrations, that is, is held so as to be movable in the width direction between the rack rows 1 and 1, the ceiling shielding member 4 can be shielded even if each rack 2 moves differently during an earthquake. The member 4 is not damaged. The fixed-side ceiling rail 3 and the ceiling shielding member 4 are fixed by a rubber attachment 15.

  In this embodiment, the ceiling shielding member 4 is lightweight as a structure in which a resin plate 6 having a continuous tunnel-like space formed therein is fitted inside a steel frame having a unit length corresponding to the width of the rack 2. However, it is not limited to this structure. However, it is preferable to have a certain degree of rigidity.

  As shown in FIG. 1, a passage shielding member 5 is provided at the end of the rack row 1. In this embodiment, the passage shielding member 5 has a sheet shape, and the upper end thereof is supported by the upper rail 7. In this embodiment, a plurality of substantially L-shaped arm portions 8 are fixed toward the outside as shown in FIGS. 4 and 5 on the frame portion of the ceiling shielding member 4 attached to the rack 2 at the end portion. The upper rail 7 is engaged with the arm portion 8. As shown in FIGS. 4 and 5, the end portions on the side of the passage shielding member of the ceiling rails 3 on both sides are protruded from the ceiling shielding member 5 to constitute the support portion 9 of the upper rail 7. In this embodiment, the support bracket 10 is separately attached to the end portion of the ceiling rail 3 to form the support portion 9. However, the end portion of the ceiling rail 3 and the support portion 9 may be integrated. The support fitting 10 also has an effect of preventing leakage of cooling air from a space between the vertical rail 14 and the upper rail 7 described later.

  The passage shielding member 5 is preferably made of a vinyl sheet, and is provided with a central fastener 11 that is opened and closed at the center when a person enters and exits and left and right fasteners 12 that can be greatly opened at both sides when the device is loaded. Even when a person goes in and out, the left and right fasteners 12 may be opened, or equipment may be carried in with the central fastener 11 opened, and this point is not particularly limited.

  The passage shielding member 5 is wound around the top surface of the upper rail 7, and then fixed by a substantially L-shaped fixed rail 13 shown in FIG. 8, and is firmly fixed to the upper rail 7. In addition, the side part of the channel | path shielding member 5 is latched by the inner surface of the vertical rail 14 of the cross-sectional substantially U shape fixed to the side surface of the rack with a hook_and_loop | surface fastener. Since a force is applied to the sheet which is the passage shielding member 5 in the pushing direction by the pressure of the cooling air in the passage, it is preferable that the locking portion of the sheet is locked to the parallel piece outside the vertical rail 14.

  With such a structure, the passage shielding member 5 can be locked with a simple configuration, preventing the cooling air from leaking out, and even when a person, a carrying-in device, or the like comes into contact with the passage shielding member 5, Will not come off and be damaged. In particular, if the structure is such that the side portion is locked by a vertical rail 14 having a U-shaped cross section, the leakage of cooling air can be effectively prevented, and the side surface of the passage shielding member 5 can be concealed from the front surface. Is excellent. The vertical rail 14 may be a substantially L-shaped bracket having no side on the rack side. In this way, by using a substantially L-shaped or substantially U-shaped rail or the like including a vertical piece and a parallel piece with respect to the side surface of the rack, it is possible to prevent the seat from being locked and the cooling air from leaking.

  In addition, if a weight is put in the lower part of the sheet | seat which is the channel | path shielding member 5, the fluttering by the flow of cooling air can be prevented and the leakage of cooling air can be prevented. In order to put the weight, the lower end of the sheet is thermally welded to form a roll, and the weight can be put therein. Further, the weight may be directly bonded to the lower end of the sheet. If the weight is used in this way, a thin sheet with a low price can be used as the passage shielding member 5. Further, if the sheet is thick, flapping can be suppressed by the weight of the sheet, so that it is only necessary to form a notch, and a fastener can be dispensed with.

  In this embodiment, the ceiling shielding member 4 and the ceiling rail 3 are configured to have substantially the same dimensions as the lateral width of the rack 2, and the support portion 9 is configured separately from the upper rail 7, at the end of the passage shielding member. The support bracket 10 is fixed to the ceiling rail 3 with screws so as to protrude from the side surface of the rack 2. Since the ceiling rail 3 is fixed to the ceiling shielding member 4 and is mounted on the support portion 9 at the end of the ceiling rail 3 of both racks 2 on the side of the passage shielding member, the load can be appropriately supported. In this embodiment, since the support portion 9 is obtained by fixing the support bracket 10 provided separately to the ceiling rail 3, the same ceiling rail 3 of any rack 2 can be used. When the ceiling rail 3 used for the rack is produced exclusively, the ceiling rail 3 and the support fitting 10 that is a support portion can be integrally formed. The support portion 9 is located between the upper rail 7 and the U-shaped vertical rail 14 to prevent cooling air from leaking. The vertical rail 14 is fixed to the rack 2, and a gap is formed between the vertical rail 14 and the upper rail 12 so as not to interfere in the event of an earthquake.

  As described above, according to the present invention, it is possible to provide a rack row passage shielding structure that has a simple configuration and that is not damaged during an earthquake and that has an excellent aesthetic appearance.

  In the embodiment of the first aspect of the invention described above, the upper rail 7 that supports the upper portion of the passage shielding member 5 is fixed to the ceiling shielding member 4. Since the ceiling shielding member 4 is supported so as to be capable of absorbing vibration, that is, movable with respect to the rack row 1, the upper rail 7 is not destroyed by the earthquake. However, as in the second aspect of the invention, the end portions on the side of the passage shielding member of the ceiling rails 3 on both sides protrude from the ceiling shielding member 4 to be the support portion 9 of the upper rail 7, and the upper rail 7 It is also possible to have a structure in which the upper rail is mounted and supported on the other support portion 9 without being fixed. This structure can also protect the upper rail 7 from being destroyed by an earthquake.
