DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves gutter for attaching an eaves gutter to an eaves of a building.

[0002]

2. Description of the Related Art An eave gutter hanging tool for attaching an eave gutter to the eaves of a building has ear receiving portions formed at both ends for supporting gutter ears as described in, for example, Japanese Patent Application No. 52-45679. And a spring plate fixed to the center of the support rod by fastening bolts and nuts. At both ends of the spring plate, gutter ears supported by ear support portions of the support rod are provided. In some cases, an ear holding portion is provided to press against the receiving portion.

[0003]

However, in such a conventional eaves gutter, when the bolts and nuts are loosened, the support rod and the spring plate can rotate about the bolts. Therefore, the position of the ear receiving portion of the support rod and the position of the ear pressing portion of the spring plate are relatively displaced, and there is a possibility that the gutter ear may fall off the ear receiving portion.

Further, in the eaves gutter, when a load is applied to the spring plate from above or below, the spring plate is elastically deformed around the bolt position, that is, substantially at the center of the spring plate as a fulcrum. If a thick spring plate is not used, there is also a risk that the gutter ears may come off without the pressing of the ear pressing part.

The present invention focuses on the above-mentioned problems, and prevents the spring plate from rotating, and at the same time, makes it possible to prevent the falling off of the gutter ears by using the holding down of the ear holding portion. It is intended to provide hanging equipment.

[0006]

In order to achieve the above object, according to the eaves gutter hanging tool of the present invention, a support rod having ear receiving portions formed at both ends for supporting gutter ears, A spring plate which is attached to a central portion via a fixing tool and has ear holding portions for holding gutter ears formed at both ends, wherein the supporting rod has a concave or convex shape. The spring plate is formed in a cross-sectional shape having a stop portion, and the spring plate is formed in a cross-sectional shape having an engaging portion engaged with a locking portion of the support rod, and is fixed to the ear receiving portion of the support rod. The fixing means for fixing the spring plate to the supporting rod is provided between the tool and the support.

[0007]

According to the eaves gutter hanging device of the present invention, the rotation of the spring plate about the fixing device is restricted by the engaging portion of the spring plate engaging with the locking portion of the support rod, and It is also restricted by the provision of fixing means for fixing a spring plate to the support rod between the ear receiving portion of the support rod and the fixing tool. Therefore, even if a load acts on the spring plate from the lateral direction due to thermal expansion and contraction of the eaves gutter, the spring plate can be prevented from rotating.

Further, since the spring plate is formed in a cross-sectional shape having an engaging portion which engages with the locking portion of the support rod, the spring plate has a higher bending rigidity than a flat cross-sectional shape, so that the ear gland is pressed. The spring force of the part can be increased.

Further, when a load acts on the spring plate from above or below, the spring plate is elastically deformed with the fixing means provided between the ear receiving portion of the support rod and the fixing tool as a fulcrum.
Therefore, the distance between the fulcrum of the elastic deformation and the ear pressing portion can be made smaller than that of the conventional one in which the fulcrum of the elastic deformation is substantially the center of the spring plate, and the spring force of the ear pressing portion can be increased.

(Corresponding to the fixing means in the claims). Further, the support rod 1 is formed in a cross-sectional shape having a locking portion 14 bulging upward from a portion of the ear receiving portion 12 except for a folded piece 12d. The support rod 1
Is formed by bending a metal strip such as stainless steel.

The spring plate 2 is provided along the lower surface of the support rod 1, and as shown in a perspective view of FIG. 3, an ear pressing portion 21 composed of a curved portion 21a and a bent piece 21b.
Are formed at both ends. That is, as shown by a two-dot chain line in FIG. 1, when the gutter ear T is supported by the ear receiving portion 12 of the support rod 1 in a state where the ear pressing portion 21 of the spring plate 2 is lifted, the ear pressing of the spring plate 2 is stopped. The part 21 exerts a spring force downward, and the gutter ear T
To the ear receiving portion 12.

As shown in FIG. 2, the spring plate 2 has a cross-sectional shape in which a portion other than the ear pressing portion 21 has an engaging portion 22 engaged with the engaging portion 14 of the support rod 1. Is formed. A hanging bolt 3 and a pair of nuts 4, 4 are fixed to the center of the supporting rod 1, and a supporting rod is provided between the hanging bolt 3 and the ear receiving portion 12 of the supporting rod 1. It is fixed by caulking one projection 13. This caulking operation is performed in advance by the spring plate 2.
A through hole 23 is formed in advance, and the projection 13 is

At the upper end of the suspension bolt 3, a felt packing 5 is mounted, and washers 6, 6 and nuts 4, 4 are mounted with the felt packing 5 interposed therebetween. That is, when a hole is formed in the folded roof, the eaves gutter can be attached to the folded roof by fastening the hanging bolts 3 and the nuts 4 provided at the upper ends of the hanging bolts 3. At this time, if the folded roof is sandwiched between the washer 6 and the felt packing 5, the folded roof can be prevented from being damaged, and the height of the eaves gutter attached to the support rod 1 is determined by the height of the nut 4. Can also be adjusted.

Next, the operation of this embodiment will be described.

In the eave gutter hanging device of this embodiment, the rotation of the spring plate 2 about the hanging bolt 3 causes the engaging portion 22 of the spring plate 2 to engage with the locking portion 14 of the support rod 1. And the spring plate 2 is fixed between the ear receiving portion 12 of the support rod 1 and the suspension bolt 3. Therefore, even if a load acts on the spring plate 2 from the lateral direction due to thermal expansion and contraction of the eaves gutter, the spring plate 2 can be prevented from rotating.

The spring plate 2 is provided with a locking portion 14 of the support rod 1.
Since it is formed in a cross-sectional shape having the engaging portion 21 that engages with the rim, the bending rigidity is higher than that having a flat cross-sectional shape, and the spring force of the ear pressing portion 21 can be increased.
