Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a rain gutter support metal fitting that is installed in a fixed position along the eaves to collect rainwater on the roof and guide it to the ground. .

(Prior Art) Since eaves rain gutters are used to collect rainwater on the roof and guide it to the ground, they are generally attached to the tips of the eaves using supporting metal fittings in consideration of the flow gradient. Such rain gutters, especially large, rectangular gutters, often have ear edges formed integrally at the upper ends of both the front and back sides, and are often attached using support fittings designed to engage and hold the edges. Conventional support fittings, for example, as seen in Japanese Utility Model Publication No. 17632/1980, are of the type in which both ends of a horizontal support rod are formed in a U-shape facing inward, and the rims are engaged from above to suspend the gutter. It is to be held in However, large square gutters made of plastic are easily deformed by external pressure, so simply engaging and holding the ear edge from the outside with a U-shaped engaging part makes it unstable to hold the engagement. When exposed to wind pressure, or when the water pressure increases due to an increase in the amount of rainwater flowing through the gutter, the front side plate or rear side plate will displace forward or backward, and the edge of the ear will disengage from the engagement part of the support fitting. There is a problem. For this reason, auxiliary locking pieces of various shapes made of leaf springs are installed on the inside of the horizontal support rod, but this does not prevent vertical movement and also causes backlash in the front and back directions. The current situation is that complete prevention of withdrawal has not yet been achieved.

(Problem to be solved by the invention) The present invention has been made in view of the above-mentioned problems of the conventional technology, and its purpose is to securely and easily remove the rain gutter with simple work. In addition to being able to be fixed, it also provides stable support against strong wind pressure from the front and large water pressure generated on the inner surface of the rain gutter due to an increase in the amount of rainwater, and reliably prevents deformation of the front and rear side panels. To provide a rain gutter supporting metal fitting that completely engages and maintains edges, does not have rattling like conventional ones, has a simple structure, and can be implemented at low cost.

(Means for Solving the Problems) In order to achieve the above object, the rain gutter support fitting of the present invention engages the upper edge edges of the front and back sides of the gutter with both ends of the horizontal support rod made of band metal fittings. In a rain gutter support metal fitting that is provided with an ear-engaging part for holding and a hanging rod in the middle part, one ear-engaging part of the horizontal support rod corresponding to the front ear edge is connected to a stepped part on the inner surface of the ear edge. It has an L-shape in which the vertical protrusion is bent upward so that it is inserted into the downward U-shaped vertical groove from below while being locked on the shoulder, and the other engaging part is inserted into the ear edge from below. A head that is formed into a U-shape by a lower piece, a vertical part, and an upper piece so as to engage and hold each other, and is movable so that it can be pulled out only upwards so as to abut and engage with the inner surface of the gutter on the surfaces of both ends of the horizontal support rod. It is equipped with a locking pin.

In the rain gutter support metal fitting, it is desirable that a hanging piece is connected to the lower piece of the ear engaging portion of the horizontal support rod so as to contact and support the outer surface of the gutter from the lower jaw of the ear edge.

(Function) The horizontal support rod 1 is fixed to a mounting portion 11 on a vertical wall surface or the like by attaching the suspension rod 7 to the mounting bracket 10. To attach the gutter 2 to the horizontal support rod 1, proceed as follows. First, the vertical protrusion 5a at the front end of the horizontal support rod 1 is inserted into the downward U-shaped vertical groove 3b of the front edge 3 of the gutter 2 and locked therein. Then, while being supported by the shoulder 3a on the inner surface of the front ear rim 3, the vertical protrusion 5a is held between the front and rear pieces 3c, 3d of the front ear rim from both front and rear sides. After the locking pin 8 is engaged, the first
Engage as shown.

Next, the rear ear edge 4 is engaged with the U-shaped engagement portion 6 at the rear of the horizontal support rod 1, but at this time, the locking pin 9 is pulled up and the rear ear edge 4 of the gutter is pressed inward. It is then displaced so that it is fitted and locked into the U-shaped portion from the inside. After this fitting, the locking pin 9 falls naturally, and the front and rear ear edges 3, 4 are engaged with the engaging portions 5, 6 at both the front and rear ends of the horizontal support rod 1, as shown in FIG.
Once engaged, the front and rear ear edges 3, 4 are completely locked not only in the vertical direction but also in the front and back direction.

When the front plate 2a of the gutter 2 is subjected to external pressure that causes it to curve inward due to strong wind pressure from the front, the lower end contact portion a of the locking pin 8 acts like a lever and pushes the inner surface of the front plate 2a. The support prevents inward bending displacement.

(Embodiment) The horizontal support rod 1 is made of a metal strip having a certain width and thickness, and has ear engaging portions 5 and 6 integrally bent at both ends thereof.

The hanging rod 7 is also made of the same strip metal as the horizontal support rod 1, and a fastener 12 such as a rivet is used at the tip to connect both 1 and 7, but the mounting position can be adjusted in the front and back direction. They are connected through the elongated hole 13 of the horizontal support rod 1. The rear end of the suspension rod 7 is a mounting part 11 on a wall surface, etc.
A mounting portion 7a is attached to the mounting bracket 10 to fix it immovably. Mounting bracket 1
It is also possible to fix it directly to a wall surface etc. without using 0. Further, by making the mounting portion 7a project upward, it can be mounted on a horizontal portion other than a vertical wall surface, for example, the lower surface of an eaves.

As the locking pins 8 and 9, those having heads 8a and 9a such as rivets and rivets are used, but other than rivets and rivets may also be used.

(Effects of the invention) Since the present invention is configured as described above, it has the following effects.

Gutters, especially large rectangular gutters, can be fixed and fixed in a stable state.

The ear rim, especially the front ear rim 3, is completely fixed in the front-rear direction because the vertical protrusion 5a at the front end of the horizontal support rod is inserted into the downward U-shaped vertical groove 3b from below, and is completely fixed in the front-rear direction. Since it is supported by the downward U-shaped top part 3e and shoulder part 3a, it is fixed immovably.

By inserting the locking pins 8 and 9, the gutter 2 can be easily and quickly attached to the horizontal support rod.

The front and rear plates of the gutter have great resistance to wind pressure and water pressure, and since they are not displaced by external pressure, there is no fear that the edge of the gutter will become disengaged. In particular, when the front plate 2a of the gutter 2 receives external pressure that causes it to curve inward due to strong wind pressure from the front, the lower end contact portion a of the locking pin 8 acts like a lever, causing the front plate 2a to Since the inner surface is supported, inward curving displacement can be prevented.

The structure is simple, and since no plate spring locking pieces or other auxiliary tools are used, the number of parts is small, the structure is durable, and it is inexpensive and advantageous in terms of cost.
