Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a downspout fitting for attaching a downspout to an outer wall of a building. 2. Description of the Related Art A conventional downspout fitting is known, for example, from Japanese Utility Model Publication No. Sho 62-155134. The downspout mounting device described in the above-mentioned publication has a groove formed on both sides of the downspout on both sides of a substantially U-shaped mounting body composed of a bottom piece and side pieces provided on both sides of the bottom piece. A locking projection corresponding to the above is protruded inward, and a holding piece is further extended forward from the locking projection. This gutter fitting is fixed to an outer wall of a building by attaching a fixing tool such as a nail or a screw to a mounting hole provided in a bottom piece, and inserting and locking a locking projection into a groove of the gutter. The downspout is fixed by holding the front end of the downspout.
It is held at a point, and even if there is a dimensional error in the downspout, the downspout can be attached without play. [0003] However, the downspout fitting described in the above publication is held by the holding pieces when the groove of the downspout is larger than the locking projection of the downspout fitting. Therefore, the holding strength for holding the downspout is not enough even if there is no backlash, and when the groove of the downpipe is smaller than the locking projection of the downpipe fixture, the holding piece is on the side of the downpipe. In some cases, there is no backlash, but there is a problem that the holding strength is not sufficient. Accordingly, the present invention has been made to solve the above-mentioned problem, and an object of the present invention is to allow a downspout to be attached without backlash even if there is a dimensional error.
Moreover, it is an object of the present invention to provide a downspout attachment with improved holding strength for holding downspouts. SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and a downspout fitting of the present invention is provided on a bottom piece and on both sides of the bottom piece. A downpipe mounting tool having a substantially U-shaped mounting body having elasticity consisting of side pieces, and a locking body attached to both side pieces of the mounting body, wherein both ends of the locking body are provided. The front holding portion and the rear holding portion are respectively provided to protrude inward, the center portion of the locking body is rotatable at one end on both sides, and the rear holding portion is formed on both sides of the downspout. When it is inserted and locked in the concave groove, the distance between both front holding portions is made smaller than the distance between the side outer peripheral surfaces of the downspout. In the downspout fitting of the present invention, a locking body is mounted on an elastic mounting body, and rear holding portions projecting from ends of the locking body are provided on both sides of the downspout. When inserted and locked in the formed groove, the distance between the two front pressing portions is smaller than the distance between the side outer peripheral surfaces of the downspout. Therefore, when the downspout is attached by expanding the mounting body, the front part from the groove of the downpipe is clamped from both sides by the elasticity of the mounting body at both front holding portions. Also, the downspout can be held at the two points of the rear holding part and the front holding part, which are inserted and locked in the groove, without rattling. Further, since the central portion of the locking body is rotatably attached to the tip of both sides, if the pit is to be disengaged and is to be moved to the front of the downspout fitting, the front of both locking bodies is to be removed. A force acts on the holding part to increase the distance between the front holding parts, and conversely, a force acts on the rear holding parts of both locking bodies to reduce the distance between the two rear holding parts. The rear holding portion cuts into the groove of the gutter, and the holding strength for holding the downspout is improved. Next, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of the present invention. FIG. 1 is a perspective view of a downspout fitting, FIG. 2 is an exploded perspective view of the downspout fitting of FIG. 1, and FIG. It is sectional drawing which shows the use condition of 1 downspout attachment. 1 is a mounting body, 2 is a locking body, 3 is a shaft rod, 4 is a downspout, and 5 is a fixture. The downspout fitting of the present invention comprises a mounting body 1 and a locking body 2, both of which are formed of elastic stainless steel. The mounting body 1 has a substantially U-shape including a bottom piece 11 and side pieces 12 and 12 provided on both sides of the bottom piece 11, and a concave portion recessed forward in a central portion of the bottom piece 11. A groove 14 is formed, and the mounting hole 15 of the fixture 5 is provided in the concave groove 14. A pair of cylindrical bearings 13 into which the shaft bar 3 can be inserted are formed on both sides of the distal end of the side piece 12, and the space between the pair of bearings 13 is cut off. The locking body 2 comprises a cylindrical support portion 25 at the center, and plate-like front and rear pieces 23 and 21 attached to both sides of the support portion 25. The cylindrical support portion 25 is configured so that the shaft rod 3 can be inserted therein, and can be inserted into a cutout portion of the pair of bearing portions 13. Also, a rear holding portion 22 corresponding to the concave grooves 41, 41 formed on both sides of the vertical gutter 4 is held at the tip of the rear piece 21 and both sides of the vertical gutter 4 are held at the tip of the front piece 23. The front holding portion 24 is provided so as to project inward. The support portion 25 of the locking body 2 is inserted between a pair of bearing portions 13 formed at the tip of the side piece 12 of the mounting body 1, and a shaft rod is provided in the bearing portion 13 and the support portion 25. 3 is inserted, and the locking main body 2 is rotatably mounted around the support portion 25 as a fulcrum. When the rear holding portion 22 of the locking body 2 is inserted and locked in the concave groove 41 of the vertical gutter 4, the distance between the front pressing portions 24, 24 is smaller than the distance between the side outer peripheral surfaces of the vertical gutter 4. The front portions of the downspout 4 can be clamped from both sides by the front pressing portions 24, 24. Next, the operation of the present embodiment will be described while explaining how to use the downspout fitting of the present embodiment having the above-described structure. First, a fixing tool 5 such as a nail or a screw is inserted into a mounting hole 15 provided in the bottom piece 11 of the mounting main body 1, and a gutter mounting tool is fixed to an outer wall of a building at a predetermined interval. The distance between the two locking bodies 2, 2 of this gutter fixture is expanded to expand the gutter 4
The rear holding portion 22 protruding from the rear piece 21 of the locking body 2 is inserted and locked in the concave groove 41 formed on both sides of the vertical gutter 4, and the front piece 23 of the locking body 2 is inserted. The front side of the groove 41 of the downspout 4 is clamped from both sides by a front holding portion 24 protruding from the bottom. Then, even if there is some dimensional error in the downspout 4, the downspout 4 can be held without backlash since it is sandwiched by the two points of the rear holding section 22 and the front holding section 24. Further, the locking body 2 is a side piece 1 of the mounting body 1.
Since the shaft 2 is rotatably attached to the front end thereof, if the shaft 4 is to be moved forward in order to come off, the front holding portions 24 of the locking main bodies 2, 2 are provided with the front portions. A force for increasing the distance between the pressing portions 24, 24 acts, and conversely, the rear pressing portions 22, 2,
2, a force acts to reduce the distance between the two rear holding parts 22, 22, and the rear holding part 22 bites into the concave groove 41 of the downspout 4 to improve the holding strength for holding the downspout 4. I do. The gutter fixture of the present invention holds the gutter without backlash at two points, the rear holding portion and the front holding portion, even if the gutter has some dimensional error. Therefore, there is an effect that it is possible to prevent the downspout from rumbling or being damaged due to the wind. Furthermore, if the pit is to be moved forward in order to come off, the rear retainer will bite into the groove of the pit and the holding strength for holding the pit will be improved. There is an effect that it can be prevented from being disengaged by being fanned, and can be used with confidence.
