[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a retractable eaves trough in which eaves gutters are put in and taken out at the eaves side. In this state, the impact of falling snow and damage to the eaves gutter due to the snow load are prevented, and the storage box for storing the eaves gutter can be accurately placed under the eaves. It is related to the technology.

[Prior Art] Conventionally, there has been provided a retractable eaves gutter that can be freely put in and taken out from under the eaves, and the present inventor has also provided various types. For example, as shown in FIG. 4, these are provided with a storage box body 2 having a front opening under the eaves, and the eaves gutter 1 is stored in the storage box body 2 so as to project and retract. Yes,
The eaves gutter 1 is moved by expanding and contracting a cylinder B ′ as a driving means B installed in the inner part of the storage box body 2. And when installing the storage box 2 in which the eaves gutter 1 is stored under the eaves,
A connecting support piece 3 is provided so as to project upward from the top plate 2a of the storage box body 2, and the upper end of the connecting support piece 3 is fixed to a rafter 4 for attachment.

[Problems to be Solved by the Invention] However, in the above-described conventional example, when the arrangement state of the rafters 4 is different at the construction site or an error occurs in the length dimension of the connection support piece 3. In such a case, it takes a lot of time to install, and if the upper end of the connecting support piece 3 is fixedly attached to the rafter 4 in such a state, the storage box body 2 is mounted in an inclined state. However, there is a problem in that the dimensional error cannot be dealt with at the construction site and the movement of the eaves gutter 1 will be hindered if the storage box 2 is attached in a tilted state.

The present invention is intended to solve the above problems, and an object thereof is to allow a storage box body to be mounted horizontally under an eaves even if a dimensional error occurs in a mounting portion. It is to provide a retractable eaves gutter.

[Means for Solving the Problems] In order to achieve the above object, the retractable eaves gutter according to the present invention has a storage box body 2 having a front surface open toward the outdoor side, disposed under the eaves. The eaves gutter 1 which can move forward and backward in the front of the eaves is installed inside the eaves 2, and the connecting support piece 3 projecting upward from the top plate member 2a of the storage box body 2 is adjusted to the height adjusting means D. It is connected to the lower surface of the roof 23 via.

[Operation] Normally, by projecting the eaves gutter 1 from the storage box body 2 and arranging it in front of the eaves, the rainwater flowing down from the roof can be received. It is possible to prevent damage to the eaves gutter 1 due to a falling impact of snowfall or a snowfall load by being stored in the storage box body 2 and positioned below the eaves. When mounting the storage box body 2 in which the eaves gutter 1 is stored, the height is adjusted through the height adjusting means D, so that the connection support piece 3 can be mounted horizontally under the eaves.

[Embodiment] Hereinafter, the present invention will be described in detail based on an illustrated embodiment.

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, the bottom plate 2b, both side plates 2c and the back plate 2d are formed into a generally U-shaped cross section with an open front surface, and when mounted under the eaves, a plurality of protrusions projecting upward from the top plate 2a are provided. The connection support piece 3 is connected to the lower surface of the roof 23, and the rear end of the bottom plate 2b extending rearward from the back plate 2d is installed under the eaves so as to contact the outer wall 5 of the building. In the illustrated embodiment, the upper end of the connecting support piece 3 is connected to the rafter 4, but the connecting support piece 3 is not limited to this and may be connected to a roof base material or the like. It may be. At this time, the connecting support piece 3 is connected to the lower surface of the roof 23 via the height adjusting means D. The height adjusting means D has a vertical piece 24a and a horizontal piece 2 as shown in FIGS.
The main body is constituted by a connecting member 24 formed in an L shape with 4b, and the horizontal piece 24b is fixed to the upper surface of the top plate 2a by a mounting screw 25, and the vertical piece 24a is connected and supported by a mounting screw 25. It is connected to the lower end of the piece 3. The vertical piece 24a is provided with a long hole 26 in the vertical direction, and the height can be adjusted by adjusting the mounting position in the long hole 26 up and down. By adjusting the length of 3, the storage box 2 can be arranged horizontally under the eaves. Further, in the illustrated embodiment, the connection support pieces 3 are provided on the upper surface of the top plate 2a at two positions in the front-rear direction, but they are also provided at regular intervals in the longitudinal direction. Various changes are made depending on the mounting position and the length of the storage box 2. As shown in FIGS. 2 and 3, rails 6 are attached to the lower surface of the top plate 2a at regular intervals in the front-rear direction (indoor / outdoor direction),
A slide rod 7 is slidably fitted in the rail 6. A pair of support rods 8 are hung from the slide rods 7, and the lower ends of the support rods 8 are connected to eaves gutter suspenders 9 that suspend and hold 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 to the rear (back inside the storage box 2), bolt
10 is projected. 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 11 and the bolt 1
The front-rear moving means A is constituted by 0, 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.
The chain 13 constitutes a tuning means C for tuning the adjacent front-rear moving means A. The rotation of the chain 13 simultaneously drives the adjacent front-rear moving means A, and the eaves gutter 1 is driven simultaneously. The moving means A is adapted to move back and forth simultaneously over the entire length.

In the embodiment shown in FIGS. 2 and 3, the forward / backward moving means A is provided at two places, but the present invention is not limited to this and provided at two or more places. You may be like this.

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. 21 is a sprocket for tension. This sprocket 16 is meshed with a chain 13 as a tuning means C which is hung on the sprocket 11 of the adjoining forward / backward moving means A, and the rotation of the sprocket 16 via the motor 14 is transmitted to the chain 13 to move back and forth. The sprocket 11 of the means A is rotated. 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 sprocket 16 of the forward / backward moving means A is rotated by the rotation of the sprocket 16 via the chain 13, and the sprocket 11 is rotated. It seems that as the bolt rotates, the bolt 10 moves back and forth, and the eaves gutter 1 moves back and forth. And, the eaves gutter 1 is usually 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. In addition, when the snow is accumulated, the eaves gutter 1 is stored under the eaves (in the storage box body 2) via the drive means B, the synchronization means C, and the front-rear moving means A as shown by the imaginary line in FIG. It is possible to prevent the snow falling from the tip 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,
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 notch 20 is provided at the cutout at a position corresponding to the position of the vertical gutter 17 that is 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.

[Effects of the Invention] The storage type eaves gutter of the present invention has a storage box body whose front face opens toward the outside as described below, and is arranged under the eaves inside the storage box body in the front-back direction toward the front of the eaves. An eaves gutter that can be moved back and forth is installed, and a connecting support piece that projects upward from the top plate member of the storage box is connected to the lower surface of the roof through height adjusting means, so height adjustment By adjusting the height via the means, the storage box can be mounted horizontally under the eaves by the connecting support piece, even if there is a dimensional error in the mounting part The height of the storage box can be adjusted accurately by attaching the storage box under the eaves. In addition, since it is possible to attach the storage box body in the horizontal state in this way, it is possible to prevent the movement of the eaves gutter arranged inside the storage box body from being hindered. It is done smoothly.
