Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a retractable eaves gutter used in a snowy region. More specifically, the retractable eaves gutter enhances not only the storage posture but also the appearance in the use posture, and the projecting motion to the use posture. It is related to the technology that tries not to cause any trouble.

[Prior Art] Conventionally, the eaves gutter 1 used in a snowy area is stored in a storage position during a snowfall period and projected to a use position during a rainy season as shown in FIG. Is.

[Problems to be solved by the invention] However, even though the eaves gutter 1 is exposed and the appearance is deteriorated even when the eaves gutter 1 is stored in the storage position during the rainy season, the eaves is supported by a large number of support tools. In order to support the gutter 1 so that it can be retracted and retracted, individual support tools are installed on the eaves, and it takes time and effort to finish the installation, and the finish cannot be finished well. In order to solve such a problem, it is conceivable that the eaves gutter 1 is arranged so as to be projectable and storable in a storage box body having an open front, and various proposals have been made. Although the appearance can be improved when the eaves gutter 1 is stored, the eaves gutter 1 is exposed when the eaves gutter 1 is projected from the storage box body, the appearance is deteriorated, and the front is opened in the storage state. There is a problem in that a large amount of snow may enter the storage box body and damage the mechanism that causes the eaves gutter 1 to project to the use position, thereby impairing its operation.

The present invention has been made in view of such problems,
The purpose is to enhance the appearance of the eaves trough when it is projected from the storage box, and to close the front opening of the storage box when the eaves gutter is stored, to prevent snow from entering the storage box. Another object of the present invention is to provide a retractable eaves trough that can prevent the entrance of the eaves trough and prevent the movement of the eaves trough from being hindered.

[Means for Solving the Problems] In the retractable eaves gutter of the present invention, an eaves gutter 1 is movably accommodated in a storage position and a protruding position in a box-shaped storage box body 2 having an open front. A nose plate 20 is attached along the outer surface of the eaves gutter 1 over the entire length of the gutter 1, and the nose plate 20 also serves as a lid for the opening of the storage box body 2 at the storage position of the eaves gutter 1. It is characterized by.

[Operation] In this way, the eaves gutter 1 is movably accommodated in the accommodation position and the projecting position in the box-shaped accommodation box body 2 having an open front, and the eaves gutter 1 is exposed to the outdoor side over the entire length of the eaves gutter 1. By attaching the nose board 20 along the outer surface of the eaves gutter 1, the eaves gutter 1 is hidden in the storage position to enhance the appearance and the eaves gutter 1 is attached to the entire length of the eaves gutter 1 in the protruding position. The nose board 20 enhances the appearance and enhances the appearance even in use, and the nose board 20 also serves as the lid of the opening of the storage box body 2 at the storage position of the eaves trough 1, so that the eaves trough 1
The front opening of the storage box 2 in the storage state of
This prevents snowfall from entering the storage box body 2 during a snowy season when the eaves gutter 1 is stored, and prevents the protruding and retracting mechanism of the eaves gutter 1 from being damaged.

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 an eaves trough holder 9 that suspends and holds the eaves trough 1. The eaves gutter 1 is moved back and forth as the slide rod 7 slides in the rail 6. A bolt 10 is projecting rearward (backward from the inside of the storage box body 2) from an ear holding portion 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 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 22 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.

A nose plate 20 is attached along the entire length of the eaves gutter 1 along the outer surface of the eaves gutter 1 on the outdoor side. Specifically, an L-shaped support fitting 21 is connected across the front and rear support rods 8, and the nose plate 20 is connected to and supported by the support fitting 21, but the nose plate 20 can be formed by another configuration. It may be supported.

Although the eaves gutter 1 is driven and moved by the driving means D and the like in the embodiment, it may be manually moved.

[Effects of the Invention] In summary, according to the present invention, the eaves gutter is movably housed in the storage position and the projecting position in a box-shaped storage box whose front is opened, and the eaves gutter is provided on the outdoor side of the eaves over the entire length of the eaves. Since the nose plate is attached along the outer surface, the eaves gutter is hidden in the stowage position of the eaves to enhance the appearance, and it is attached over the entire length of the eaves gutter in the protruding state. There is an advantage that the appearance can be enhanced by the nose plate and the appearance can be enhanced even in the state of use.
Moreover, since the nose plate doubles as a lid for the opening of the storage box in the storage position of the eaves gutter, the front opening of the storage box is closed when the eaves gutter is stored, and snow is stored during the snowfall when the eaves gutter is stored. There is an advantage that it prevents entry into the box and does not damage the protruding and retracting mechanism of the eaves gutter.
