As shown in FIG. 5, the conventional evacuation device is constructed by erecting a rising wall 3 around the entire periphery of an upper opening 2 of a storage frame 1, and closing this upper opening 2 with a lid 4. By making the upper edge of the rising wall 3 protrude from the floor 5 of the balcony, rainwater is prevented from penetrating into the storage frame 1.

[Problem that the invention seeks to solve]

However, when such an evacuation device is installed on a balcony, the lid 4 protrudes from the floor 5, which not only looks unsightly but also prevents the effective use of the balcony, and prevents the lid of the evacuation device from being used. This had drawbacks such as the possibility of tripping over the body 4 and injuring oneself.

The present invention has been made in response to such circumstances, and provides an evacuation system that can eliminate various drawbacks caused by the cover body 4 of the evacuation device protruding from the floor surface 5 of the balcony. The purpose is to provide equipment.

[Means for solving problems]

In FIG. 1, an evacuation device according to the invention is shown.

This evacuation device is an opening 6 opened on the balcony.
The storage frame 1 has a substantially rectangular shape in plan view and is fitted and fixed to the storage frame 1 and has an evacuation device (not shown) stored therein, and a lid body 4 that opens and closes the upper opening 2 of the storage frame 1. A rising wall 3 is erected around the entire periphery of the upper opening 2 of the storage frame 1 to surround the upper opening 2.

On the other hand, horizontal pieces 7 are extended outward from the vicinity of the lower ends of these rising walls 3, and by making these horizontal pieces 7 continuous with each other, a flat portion 8 is formed around the rising walls 3. At the same time, side walls 9 are erected on three sides of the outer peripheral edge of such a flat portion 8.

[Effect]

The evacuation device of the present invention configured as described above is
To form three gutter-like flat parts 8 formed by the rising wall 3 and the horizontal piece 7 that are continuous with the upper opening periphery of the storage frame 1, and one flat part 8 that opens outward. By simply fitting and fixing it into the opening 6 of the balcony, the rising wall 3 prevents rainwater from entering the storage frame 1, and the flat part 8 surrounded by the rising wall 3 and the side wall 9 serves as a rain gutter, for example, the side wall 9 is connected to a drain 10 formed on the balcony floor 5.
Rainwater can be guided to the drainage ditch 10 by bringing the flat surface part 8, which is not provided with an upright surface, into contact with the drainage ditch 10.

The drainage function formed in the evacuation device itself eliminates the need for the rising wall 3 to protrude from the floor surface 5 of the balcony, and eliminates the need for the lid body 4 to protrude from the floor surface 5 of the balcony. Both can prevent rainwater from entering the storage frame 1.

An upper opening 2 is formed by closing the upper opening periphery with an upper frame member 1b fixed to the upper end, and the end of the upper frame member 1b is bent upward to form a rising wall 3. is formed.

Further, in this embodiment, a support wall 11 is further erected inside the rising wall 3, and a seal rubber 13 is attached to the entire periphery between the walls 12 formed by the rising wall 3 and the supporting wall 11. By doing so, it is possible to prevent noise and the like when the lid body 4 is closed, and also to improve sealing performance.

In this embodiment, the side wall 9 is connected to the upper frame member 1
By bending the opposite end of b to have a U-shaped cross section at approximately the same height as the top surface 4a of the lid body 4, when the end is fitted and fixed to the opening 6 of the veranda, there is a cutout at the top edge 9a of the side wall 9. It is becoming effective.

In this way, by making the upper edge 9a of the side wall 9 of the storage frame 1 and the upper surface 4a of the lid 4 approximately at the same height, the position of the upper edge 9a of the side wall 9 is adjusted to the upper surface 4a of the lid 4. Since this will indicate the height, by constructing with this side wall 9 as a reference, the floor surface 5 of the lid body 4
This can reliably prevent protrusion from the surface.

In this embodiment, the rising wall 3, the plane part 8, and the side wall 9 are formed by welding and fixing the upper frame member 1b, which is formed by bending these members, to the frame member 1a. Alternatively, the rising wall 3 may be formed in advance on the frame material 1a, and a member having an L-shaped cross section having a flat portion 8 and a side wall 9 may then be attached by appropriate means.

On the other hand, the lid 4 is formed by drawing a steel plate, for example, and is connected to the storage frame 1 via a hinge member 14, and a handle 15 attached to one end of the lid 4 is lifted up. As shown in FIG. 3, by rotating the lid 4, the upper opening 2 of the storage frame 1 can be opened.

Further, as shown in FIG. 3, the evacuation device 16 in this embodiment is composed of a telescopic ladder that is telescopic and has an upper end rotatably connected to the side wall of the storage frame 1. When in use, it is stored within the storage frame 1.

In addition, in FIGS. 2 and 3, the reference numeral 17
