  A planter cover fixing plate is fixed to both ends of the standing portion 93 of the receiving portion 9 by bolts and nuts. The planter cover 11 is formed to be longer in the horizontal direction than the receiving part 9 so as to cover the receiving part 9, and is formed so that the upper part is released and the side part is curved from the lower part. End cover 12 that covers the top of the planter cover 11 is formed at both ends of the planter cover 11. Since the side part is formed so as to bend from the lower part of the planter cover 11, as shown in FIG. 8, planting planted in the planter 10 is performed by the planter cover 11 provided on the planter 10. Since it is upward and extends in the outdoor and indoor directions, the planting appears to be large when viewed from below the outdoor side, and the design is improved and the line of sight is further blocked. By placing the planter 10 in which the planting is planted in the receiving part 9 of the horizontal member 6 in this way, the opening 4 can be greened to block sunlight, and the opening 4 can be blinded or ventilated. The cooler wind that has passed through the planting can be taken indoors. Instead of placing the planter 10 in which the planting has been planted, artificial flowers or the like may be placed on the entry portion horizontal member 7. If it does in this way, since weight can be made light compared with the case where planting is mounted, it can operate more easily when ensuring an emergency entrance.

  In this embodiment, as shown in FIG. 11, an end fixing angle 8 is fixed to the support piece 5 protruding from the right wall surface W3 by a nut 15 and a bolt 16 with a torque release lever. The fixed side plate 95 and the movable side plate 96 of the part 9 are also fixed to each other by the nut 19 and the bolt 20 with a torque release lever. By joining the bolts 16 and 20 with torque release levers and the nuts 15 and 19 in this way, the connection between the bolts 16 and 20 and the nuts 15 and 19 can be easily loosened without using a tool. Although it is possible to easily secure the entrance, the present invention is not limited to this.

  For example, as shown in FIG. 12, the support piece 5 protruding from the right wall surface W3 and the end fixing angle 8 are joined by a bolt 16a and a wing nut 15a instead of a nut 15 and a bolt 16 with a torque release lever.

The remaining nut 15 and the bolt 16 with torque release lever are the “horizontal axis” in the present invention.

  Next, the nut 19 and the bolt 20 with torque release lever that join the fixed side plate 95 and the movable side plate 96 of the receiving portion 9 are removed. A tool such as a wrench is used by releasing a tightening torque between a nut and a bolt by causing a torque release lever, similarly to the joining of the support piece 5 protruding from the right wall surface W3 and the end fixing angle 8. The nut 19 and the bolt 20 with the torque release lever can be easily removed without any trouble. Here, the nut 19 and the bolt 20 with torque release lever that join the fixed side plate 95 and the movable side plate 96 of the receiving portion 9 correspond to “predetermined joining means” in the present invention.

  As described above, of the four nuts 15 and the bolts 16 with torque release levers that join the support piece 5 protruding from the right wall surface W3 and the end fixing angle 8, the nut 15 serving as the horizontal axis and the torque. When the three nuts 15 and the bolt 16 with the torque release lever are removed except for the bolt 16 with the release lever, and the joint between the fixed side plate 95 and the movable side plate 96 of the receiving part 9 is released, as shown in FIG. Due to the weight of the horizontal member 7, the right end fixing angle 8 and the receiving portion 9 rotate so as to incline around the bolt 16 with a torque release lever of the horizontal shaft.

  By repeating the same operation and tilting the four entrance horizontal members 7 adjacent in the vertical direction as shown in FIG. 15, it is possible to secure an emergency entrance having a size in which a circle having a diameter of 1 m can be inscribed. it can. This makes it possible to secure a legal emergency entrance, but if a larger entrance is required, remove the bolt 16 with a torque release lever that forms the horizontal axis as shown in FIG. The entrance horizontal member 7 can be completely removed from the wall surfaces W2, W3 on both sides. One end of a wire 21 is fixed to the support piece 5 protruding from the right wall surface W3, and the other end of the wire 21 is fixed to an end fixing angle 8 joined to the support piece 5. Thereby, even if the entrance horizontal member 7 is completely removed from the left and right wall surfaces W2, W3, the entrance horizontal member 7 can be prevented from falling to the ground.

  11 to 14 and 16, the bolts 16 and 20 with torque release levers, which are disposed on the back side of the standing portion 93 of the receiving portion 9 and cannot be visually recognized, other bolts 13, nuts 14, 15, 19, The stationary side plate 95 and the movable side plate 96 of the receiving portion 9 are shown for convenience of explanation.

  As described above, according to the louver structure 1 with an entrance according to the present embodiment, one end of the entrance horizontal member 7 provided at the same height as the opening 4 in the horizontal member 6 can be attached to and detached from the left wall W2. The other end can be swung by a bolt 16 with a torque release lever which is a horizontal axis attached to the right wall surface W3, so that when one end of the entry portion horizontal member 7 is detached from the wall surface W2, the bolt which becomes the horizontal axis Rotating about 16 as an axis, one end side of the entry portion horizontal member 7 is moved downward by its own weight, and the entry portion horizontal member 7 is inclined, whereby an emergency entrance can be secured. In this way, the emergency entrance can be secured by a simple operation in an emergency while firmly supporting the entrance horizontal member 7 with a relatively simple configuration.
