Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a retractable eaves gutter in which an eaves gutter is put in and out at an eaves. This is intended to prevent the eaves gutter from being damaged due to the falling impact of snow and the snow load.

[Related Art] Conventionally, a retractable eaves gutter which can be freely put in and out of the eaves below the eaves has been provided, and the inventor has also provided variously. For example, as shown in FIG. 4, a storage box 2 having a front opening is provided under the eaves.
The eaves gutter 1 is housed inside the storage box 2 by extending and retracting a cylinder B ′ as a driving means B installed in the back of the storage box 2. The gutter 1 is moved. At this time, the cylinders B 'are arranged at regular intervals along the longitudinal direction of the eaves gutter 1. When moving, the eaves gutter 1 is moved by simultaneously expanding and contracting a plurality of cylinders B'.

[Problems to be Solved by the Invention] However, in the above-described conventional example, the eaves gutter 1 is moved by simultaneously operating the cylinders B '. If the expansion and contraction states of the cylinders B 'are different, the eaves gutter 1 cannot be moved smoothly, and there is a problem that the eaves gutter 1 from the eaves varies, and if the eaves gutter 1 becomes long, Along with this, it is necessary to use a large number of cylinders B 'as the driving means B, and there has been a problem that the cost is high.

The present invention seeks to solve the above problems,
The purpose is that the eaves gutter can be moved smoothly at the time of putting in and out, and the eaves gutter can be moved by one driving means without high cost. The components constituting the drive means and the tuning means can be easily and easily mounted under the eaves, and the components can be sufficiently protected from rain and wind, so that the eaves gutter can be smoothly moved back and forth for a long time. Another object of the present invention is to provide a storage-type eaves gutter capable of storing the storage box compactly under the eaves and improving the appearance of the storage box.

[Means for Solving the Problems] In order to achieve the above object, a retractable eaves gutter according to the present invention has a storage box 2 which is opened forward under the eaves, and an eaves gutter is provided inside the storage box 2. A plurality of forward and backward moving means A for horizontally moving the gutter 1 in the front-rear direction between a protruding position below the eaves and a storage position in the storage box 2, and one driving means B for driving each of the plurality of forward and backward moving means A And each of the plurality of back and forth moving means A
And a tuning means C for interlocking the one driving means B with the tuning means C.

[Operation] The eaves gutter 1 is moved in and out of the eaves below by driving each of the front and rear moving means A by one driving means B via the interlocking means C. In the protruding state, rainwater flowing down from the rooftop can be received, and when snowfall is stored under the eaves, it can be received by the eaves gutter 1 even if the snowfall on the roof falls from the rooftop. There is no snow on the eaves gutter 1 and the eaves gutter 1 can be prevented from being damaged by the impact of falling snow or the load of the snow. In addition, since the forward / backward moving means A, the driving means B, and the tuning means C can be housed in a single storage box 2 to form a unit, the components constituting the forward / backward moving means A, the driving means B, and the tuning means C can be moved under the eaves. It can be installed easily and with good appearance, and each part is well protected from rain and wind.
Can be maintained for a long period of time, and by further horizontally moving the eaves gutter 1 in the front-rear direction, the size of the storage box 2 can be reduced in the vertical direction.

Hereinafter, the present invention will be described in detail based on illustrated embodiments.

The eaves gutter 1 formed in a U-shaped cross section with an open upper surface is the first
As shown in the figure, it is installed inside a storage box 2 which is opened under the eaves and opens on the roof side. The storage box 2 is formed in a substantially U-shaped cross-section with a front opening by a top plate 2a, a bottom plate 2b, both side plates 2c, and a back plate 2d. The connecting support pieces 3 projecting toward the eaves are connected to the rafters 4 under the eaves, and are installed under the eaves such that the rear end of the bottom plate 2b extending rearward from the back plate 2d abuts against the outer wall 5 of the building. . FIG. 2 shows the lower surface of the top plate 2a.
As shown in FIG. 3, rails 6 are attached at regular intervals in the front-rear direction (indoor / outdoor direction), and slide bars 7 are slidably fitted in the rails 6. A pair of support rods 8 are suspended from the slide rods 7, and the lower ends of the support rods 8 are connected to eaves gutter suspenders 9 that hold the eaves gutter 1. The eaves gutter 1 is moved back and forth by the slide bar 7 sliding in the rail 6. A bolt 10 projects from the ear holder 9a provided on the eave gutter hanging tool 9 toward the rear (inside of the storage box 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.
The inner surface of the sprocket 11 is internally threaded, and the sprocket 11 is screwed to the bolt 10. The sprocket 11 is rotatably disposed between a pair of holding plates 12 suspended below the top plate 2a, and when the sprocket 11 rotates, the bolts 10 move with respect to the holding plate 12 with the rotation of the sprocket 11. To move back and forth. The sprocket 11, the bolt 10, the support rod 8, the slide rod 7 fitted to the rail 6, and the like constitute a back-and-forth moving means A. The fore-and-aft 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 synchronizing means C for synchronizing the adjacent front-rear moving means A, and the adjacent front-rear moving means A are simultaneously driven by the rotation of the chain 13, and the eaves gutter 1 is driven before and after the simultaneous driving. The moving means A simultaneously moves back and forth over the entire length.

In the embodiment shown in FIGS. 2 and 3, the front-rear moving means A is provided at two places, but is not limited to this, and is provided at two or more places. It may be so. 2 and 3, the illustration of the bottom plate 2b and the back plate 2d of the storage box 2 is omitted.

One drive means B for driving the front-rear movement means A is provided on the lower surface of the top plate 2a constituting the storage box 2. The driving means B mainly comprises a motor 14 and a gear box 15 in which gears driven by the motor 14 are housed. By rotating the motor 14, a sprocket 16 protruding from the gear box 15 is rotated. I can do it. The sprocket 16 is meshed with a chain 13 as a tuning means C which is stretched over a sprocket 11 of an adjacent longitudinal moving means A, and transmits the rotation of the sprocket 16 via a motor 14 to the chain 13 to move the sprocket 16 forward and backward. The sprocket 11 of the means A is rotated. 21 is a sprocket for tension.
With this configuration, one driving unit B
, The plurality of front and rear moving means A are simultaneously driven while being synchronized with each other, so that the eaves gutter 1 can be simultaneously moved back and forth over the entire length.

Thus, when the motor 14 constituting the driving means B is driven, the sprocket 16 is rotated by the motor 14,
The rotation of the sprocket 16 causes the sprocket 11 of the fore-and-aft moving means A to rotate via the chain 13, and the rotation of the sprocket 11 causes the bolt 10 to move forward and backward, so that the eaves gutter 1 can be moved forward and backward. is there.
Normally, the eaves gutter 1 is made to protrude from the eaves as shown by the solid line in FIG. 1 and receives rainwater. The received rainwater is drained through the downspout 17. It is. In addition, at the time of snow, the driving means B, the tuning means C,
By storing the eaves gutter 1 under the eaves (in the storage box 2) as shown by the imaginary line in FIG.
It is possible to prevent the snow sliding down from the rooftop from being received by the eaves gutter 1 and to prevent the eaves gutter 1 from being damaged by the impact of falling snow and the load of the snow. At this time, since the forward / backward moving means A, the driving means B, and the tuning means C can be housed in a single storage box 2 to form a unit, the components constituting the forward / backward moving means A, the driving means B, and the tuning means C ( Bolt 10, Chain 13, Sprocket 1
3, motor 14 etc.) can be installed easily and with good appearance under the eaves, and the above-mentioned components can be sufficiently protected from rain and wind so that the smooth movement of the eaves gutter 1 can be maintained for a long time. Become. Furthermore, by horizontally moving the eaves gutter 1 in the front-rear direction, it is possible to reduce the size of the storage box 2 in the vertical direction, and to store the storage box 2 compactly under the eaves to improve the appearance of the storage box. Can be done. A connecting gutter connecting the downspout 1 extended from the eaves trough 1 and a downspout 18 attached along the building outer wall 5.
Numeral 19 is extendable and retractable as the eaves gutter 1 moves back and forth. Although the connecting gutter 19 in which the outer cylinder 19a and the inner cylinder 19b are slidably connected to each other is shown in FIG. 1, a connecting gutter formed in a bellows shape may be used. Things. The bottom plate 2b of the storage box 2 is provided with a cut-out portion 20 by cutting a position corresponding to the position of the vertically extending gutter 17 from the eaves gutter 1. this is,
This is because when the eaves gutter 1 is stored in the storage box 2, the downspout 17 is stored.

[Effects of the Invention] The retractable eaves gutter according to the present invention has a storage box body that opens forward below the eaves as described above, and the eaves gutter is provided inside the storage box body with a protruding position below the eaves and the storage box body. A plurality of front-rear moving means for horizontally moving in the front-rear direction with respect to the storage position, one driving means for driving each of the plurality of front-rear moving means, and interlocking the plurality of front-rear moving means with one driving means Since the tuning means is housed, the eaves gutter can be moved by one driving means, and thus the eaves gutter can be moved via one driving means, so that the cost is not increased. A part for moving the eaves gutter can be constituted, and a plurality of front / rear moving means for moving the eaves gutter are linked to one driving means via the tuning means. It is possible to perform the operation at the same time This makes it possible to smoothly move the eaves gutter without moving the eaves gutter in and out of a shifted state, thereby making it possible to keep the eaves gutter from the eaves tip in the longitudinal direction at a constant level. Further, since the forward / backward moving means, the driving means, and the tuning means can be housed in a single storage box to form a unit, the components constituting the forward / backward moving means, the driving means, and the tuning means can be easily and easily mounted under the eaves. In addition to being able to protect each part from rain and wind, the eaves gutter can be maintained smoothly fore-and-aft for a long time. The storage box can be compactly stored under the eaves to improve the appearance of the storage box.
