Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

As shown in FIG. 1, an eaves gutter 1 having an open top surface and having a U-shaped cross section is installed inside a storage box body 2 which is arranged under the eaves and opens to the outside. This storage box 2 is a top plate
2a, bottom plate 2b, both side plates 2c, and back plate 2d are formed into a substantially U-shaped cross section with a front surface open, and when mounted below the eaves, a connecting support projecting upward from the top plate 2a. The material 3 is connected to the rafters 4 under the eaves, and the bottom plate 2b extending rearward from the back plate 2d is installed under the eaves so as to abut the outer wall 5 of the building. Rails 6 are attached to the lower surface of the top plate 2a at regular intervals in the front-back direction (indoor / outdoor direction), and a slide rod 7 is slidably fitted in the rail 6. From this slide rod 7, a pair of support rods 8
And the lower end of each support rod 8 is connected to the eaves gutter suspension 9 for suspending and holding the eaves gutter 1. The eaves gutter 1 is moved back and forth as the slide rod 7 slides in the rail 6. From the ear holder 9a provided on the eaves gutter suspension 9, a bolt 110 is provided so as to project rearward (backward in the storage box body 2). The rear end of the bolt 10 is supported by a sprocket 11 attached to the top plate 2a of the storage box 2. A female screw is formed on the inner surface of the sprocket 11, and the sprocket 11 is screwed into the bolt 10. This sprocket 11 is rotatably arranged between a pair of holding plates 12 hanging below the top plate 2a, and the sprocket 11 rotates so that the bolt 10 is rotated relative to the holding plate 12 as the sprocket 11 rotates. It is designed to move back and forth. And the sprocket 1
The back-and-forth moving means A is composed of 1, the bolt 10, the support rod 8, the slide rod 7 fitted to the rail 6, and the like. The front-rear moving means A is arranged on the lower surface of the top plate 2a at regular intervals along the longitudinal direction of the eaves gutter 1.

A chain 13 is stretched over each adjacent sprocket 11, and each sprocket 11 is rotated by driving the chain 13. And this chain
The front and rear moving means A adjacent to each other are synchronized with each other by the rotation of the chain 13.
Are simultaneously driven, and the eaves gutter 1 is simultaneously moved forward and backward over the entire length by the front-rear moving means A which is simultaneously driven.

On the lower surface of the top plate 2a constituting the storage box body 2, one driving means B for driving the above-mentioned front-rear moving means A is provided.
The drive means B is mainly composed of a motor 14 and a gear box 15 in which a gear driven by the motor 14 is installed. By rotating the motor 14, a sprocket 16 protruding from the gear box 15 is rotated. I am able to do it. This sprocket 16 is meshed with a chain 13 hung on the sprocket 11 of the adjoining front-rear moving means A, and the rotation of the sprocket 16 via the motor 14 is transmitted to the chain 13, so that the sprocket 11 of the front-rear moving means A is transmitted. Is designed to rotate. With this structure, one evacuation trough 1 can be simultaneously moved back and forth over the entire length by simultaneously driving a plurality of front-rear moving means A while synchronizing them with one driving means B. .

Then, when the motor 14 constituting the drive means B is driven, the sprocket 16 is rotated by the motor 14, and the rotation of the sprocket 16 causes the sprocket 11 of the front-rear moving means A to rotate via the chain 13 and the sprocket 11 to rotate. The rotation of the bolt moves the bolt 10 back and forth, so that the eaves gutter 1 can be moved back and forth. Normally, the eaves gutter 1 is in a state of protruding from the eaves as shown by the solid line in FIG. 1, and receives rainwater. The received rainwater is drained through the vertical gutter 17. There is. Further, when the snow is accumulated, the eaves gutter 1 is stored under the eaves (in the storage box body 2) through the drive means B and the front-rear moving means A as shown by an imaginary line in FIG. It is possible to prevent incoming snow from being received by the eaves gutter 1, and to prevent the eaves gutter 1 from being damaged by the falling impact of the snow and the load of the snow. At this time, the connection gutter 19 that connects the vertical gutter 17 that extends from the eaves gutter 1 and the vertical gutter 18 that is installed along the outer wall 5 of the building is expandable and contractable as the eaves gutter 1 moves back and forth. I am doing it. In the case shown in FIG. 1, the outer cylinder 19a
Although the connection gutter 19 in which the and the inner cylinder 19b are slidably connected to each other is shown, a connection gutter formed in a bellows shape may be used. Further, the bottom plate 2b of the storage box body 2 is provided with a cutout portion 20 by cutting a position corresponding to the position of the vertical gutter 17 continuously extended from the eaves gutter 1. This is to allow the vertical gutter 17 to be stored when the eaves gutter 1 is stored in the storage box body 2.

Then, in the bottom plate 2b, the front-rear moving means A and the driving means B
An inspection opening D is opened in the bottom plate 2b and the portion where the inspection is provided, and a lid 21 is detachably provided on the inspection opening D. A hook 22 is rotatably provided on the inner surface side of the lid 21, and a handle 23 on the lower surface side of the lid 21 is rotated to rotate the handle 23.
By rotating the hook 22 integrated with the hook 22, the hook 22 is locked to the bottom plate 2b of the inspection port D, and the lid 21 is attached to the bottom plate 2b substantially flush with the hook 22. Remove from 2b,
The lid 21 can be switched to the state of being removed downward. As shown in FIG. 4, the lid 21 may also serve as the front portion 2c of the bottom plate 2b and be removed. In such a case, the lid 21 and the back plate 2d are releasably connected by the connecting fitting 24. The design of the connecting fitting 24 can be changed in various ways.

[Effects of the Invention] In summary, according to the present invention, the eaves gutter is movably accommodated in the accommodation position and the projecting position in a box-shaped accommodation box whose front is opened, and the eaves trough is provided on the lower surface of the top plate of the accommodation box. Since the drive means for drivingly moving the eaves gutter to the storage position and the projecting position is attached, the eaves gutter is stored in the back of the storage box body at the storage position while switching the eaves gutter between the storage position and the projecting position. Since the appearance can be improved and the drive means is used to move the eaves and troughs, the eaves and troughs can be moved in and out with less labor, and the entire structure is stored in the storage box, so the construction is performed in the storage box. Can be attached to the eaves part, and the workability can be greatly enhanced, and the inspection opening for the drive means is formed on the bottom of the storage box so that it can be opened and closed easily. The advantage of being able to do is there.
