In addition, the electric drive of the eaves gutter 1 is drivable so that the eaves gutter 1 can be projected and housed and the respective set positions thereof can be maintained at good positions without causing excessive protrusion and obstructing stable support. There is no such thing.

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. A bolt 10 is provided so as to project rearward (backward from the inside of the storage box body 2) from the ear holding body 9a provided on the eaves gutter suspension device 9. 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,
When the sprocket 11 rotates, the bolt 10 moves back and forth with respect to the holding plate 12 as the sprocket 11 rotates. Then, the sprocket 11, the bolt 10, the support rod 8, and the slide rod 7 fitted to the rail 6
The back-and-forth moving means A is comprised by the etc. This front-back moving means A is a top plate at regular intervals along the longitudinal direction of the eaves gutter 1.
It is located on the bottom of 2a.

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 electric 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.
By rotating the sprocket 11, the bolt 10 is moved back and forth, and the eaves gutter 1 is 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 electric drive means B and the front-rear moving means A as shown by an imaginary line in FIG. The falling snow can be prevented from being received by the eaves gutter 1, and the eaves gutter 1 can be prevented from being damaged by a falling impact of the snow and a 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,
Connection gutter 19 that slidably connects the outer cylinder 19a and the inner cylinder 19b.
However, a connection gutter formed in a bellows shape may be used. In addition, the bottom plate 2b of the storage box 2
A cutout portion 20 is provided in the cutout at a position corresponding to the position of the vertical gutter 17 which is continuously extended from the eaves gutter 1. This is eaves gutter 1
This is to allow the vertical gutter 17 to be stored when the storage box body 2 is stored.

There are provided a storage position setting sensor S ₁ for stopping the driving operation of No. ₁ and a projection position setting sensor S ₂ for detecting the maximum protruding position of the eaves gutter 1 and stopping the driving operation of the electric drive means B. Specifically, as shown in FIG. 3, the slide bar 7 on the eaves gutter 1 side is slidably inserted into the rail 6 attached to the top plate 2a, and the traveling body 21 is extended from the slide bar 7 A detected plate 22 such as a magnetic plate is attached to the traveling body 21, and a storage position setting sensor S ₁ and a protruding position setting sensor S ₂ are attached to an L-shaped metal fitting 23 fixed to the top plate 2a side. It is a thing. Then, the detected plate 22 and the storage position setting sensor S ₁
Proximity switch is formed by and, by the operation of the proximity switch, the electric drive of the electric drive means B is stopped, that is, the operation of the motor 14 is stopped, and the maximum storage position of the eaves gutter 1 is set to a predetermined position. It is a thing. Further, a proximity switch is also configured by the detected plate 22 and the protrusion position setting sensor S _2, and the operation of the proximity switch stops the operation of the motor 14 and sets the maximum protrusion position of the eaves gutter 1. . The configuration of such a proximity switch may be a magnetic switch that performs a magnetic operation, a photoelectric switch, or the like.
