Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a receiving metal fitting for fixing a vertical gutter for rainwater drainage.

(Prior art) A bracket for fixing a rectangular or round vertical gutter for rainwater drainage usually has a band shape that surrounds the outer periphery of the vertical gutter, and a tongue piece provided at one end is attached to the other side. A structure is adopted in which the device is fixed by being removably locked in a locking hole provided at the end.

However, in this locking structure, since the base of the tongue is locked at one end edge of the locking hole, a force acts in one direction, that is, in the opposite direction to the protruding direction of the tongue. However, if a force is applied in the other direction, that is, in the direction in which the tongue protrudes, the engagement can easily come off. In particular, since external forces are applied to this type of gutter from various directions, there is a high possibility that the locking portion will disengage.

(Purpose) In view of these points, the present invention aims to provide a vertical gutter receiving fitting that can prevent the locking portion from coming off as much as possible even when forces are applied from various directions. The feature is that one end of the band-shaped receiving metal body is provided with a pair of tongues that protrude in opposite directions, while the other end is provided with a pair of tongues that are shorter than the distance between the tips of the pair of tongues. A locking hole is provided with a hook and has a length longer than the distance between the tip of one tongue piece and the base of the other tongue piece, and the pair of tongue pieces are removably locked in the locking hole. The point is that it is made in such a way as to make it happen.

(Example) The present invention will be described in detail below based on the illustrated example.

FIGS. 1 and 2 show a receiving fitting according to an embodiment of the present invention, and reference numeral 1 in the figures indicates a receiving fitting main body formed in a band shape from a stainless steel plate.
It is formed into a ring shape to fix the round gutter T, and a plurality of horizontally elongated holes 2 are bored at appropriate positions on its surface. These horizontally elongated holes 2 are intended to reduce the surface area of the receiving metal body 1 in the width direction in this part, and to make the receiving metal body 1 have a structure that can be bent in both directions, and the drilling positions are selected as appropriate. .

3 is a tongue piece formed at one end of the receiving metal body 1, and this tongue piece 3 is a pair of left and right tongue pieces 3 that are cut and raised with an appropriate interval and facing in opposite directions to each other.
It consists of L and 3R.

Reference numeral 4 denotes a locking hole formed at the other end of the receiving metal body 1. The locking hole 4 locks the tongue piece and is configured to be difficult to remove. That is, the locking hole 4
As shown in FIG. 3C, the length L is shorter than the distance D between the tips of the left and right tongue pieces 3L and 3R, and It is made longer than the distance d between the roots of 3R or 3L.

In the figure, reference numeral 5 indicates an operating piece formed by bending the end on the side of the locking hole 4 outward, and 6 indicates a receiving portion formed protruding on the side of the tongue piece 3, respectively.

Therefore, in order to fix the round gutter T with this receiving metal fitting, first, this receiving metal fitting main body 1 is attached via a mounting portion (not shown) that is hung downward from the surface of the receiving portion 6 of the receiving fitting main body 1, for example. Fix it to the wall.
Next, the outer periphery of the gutter T is fixed by wrapping it around the receiving fitting main body 1. At this time, since the receiving fitting main body 1 has a plurality of horizontally elongated holes 2 bored on its surface, Even if it expands outward from that part, its elastic restoring force allows the inner surface of the receiving metal body to be brought into close contact with the outer circumferential surface of the round gutter T.

Then, pull the operating piece 5 toward the receiving portion 6 to lock the tongue piece 3 in the locking hole 4 with the end on the locking hole 4 side facing upward. Since the length of the locking hole 4 is set to be shorter than the distance D between the tips of both tongues 3L and 3R, when locking, first, as shown in FIG. Piece (Tang piece 3R on the right side in the figure)
pass through the locking hole 4, and then pull the operation piece 5 again toward the other tongue (the left tongue 3L in the figure) to lock the tongue 3L on this side into the locking hole 4. (See Figure 3 B).

The tongue pieces 3L and 3R locked in this way are
Even if a force is applied to the receiving metal body 1 from either the left or right direction, one of the metal fittings will always be locked to the edge of the locking hole 4, so that it will not come off.

FIG. 4 shows another embodiment of the present invention.
tongue pieces 13 protruding in opposite directions
R and 13L are provided offset in the width direction of the receiving metal body 11, and correspondingly, the locking hole 14 formed at the other end of the receiving metal body 11 is also aligned with both tongue pieces 13.
The holes 14a on the upper side in the figure lock the left tongue piece 13L, and the hole 14b on the lower side locks the right tongue piece. It is configured to lock 13R.

The method of use is the same as in the above embodiment, but according to this embodiment, the tongue pieces 13R and 13L are arranged above and below, which prevents the receiving metal body from coming off due to forces acting in the left and right directions. At the same time, it is possible to further prevent wobbling in the vertical direction.

5 and 6 show an example of the fastening structure of the receiving fitting related to the present invention, in which the receiving fitting main body 2
1, a circular locking plate 23 having upper and lower connecting pieces 22, 22 is formed by punching, and the locking plate 23 is pressed outward from the inside to connect the connecting pieces 22, 2.
2 is slightly extended to allow the locking plate 23 to protrude outside, while a locking hole 24 for locking the locking plate 23 is bored at the other end of the receiving metal body 21. The extent to which the plate 23 protrudes is slightly longer than the thickness of the receiving metal body 21.

Therefore, when the locking plate 23 is hooked into the locking hole 24, the arched portions on both sides of the locking plate 23 are locked on both side edges of the locking hole 24, and the force acting on the receiving metal body 21 from the left and right directions is reduced. It is possible to prevent their departure.

In addition, in the above-mentioned embodiment, explanation was given to a receiving fitting for fixing a round gutter, but the present invention can also be applied to a receiving fitting for fixing a square gutter with a similar structure, and the tongue piece and the locking hole can also be applied to a receiving fitting for fixing a square gutter. Regarding the shape and arrangement direction, various design changes can be made without departing from the spirit of the present invention. For example, the tongue piece may be arranged vertically at one end of the metal fitting body, and the locking hole may be vertically elongated. It can also be used as

(Effects) As described above, according to the present invention, a pair of tongue pieces protruding in opposite directions is provided at one end of the receiving metal body, and this tongue piece is attached to the other end of the receiving metal fitting body. By removably locking into the locking hole, both ends of the receiving metal body are fixed.
Moreover, the locking hole has a length that is shorter than the distance between the tips of the pair of tongues and longer than the distance between the tip of one tongue and the base of the other tongue. Because of this, once both tongues are locked in the locking hole, each tongue will be caught on both edges of the locking hole, and will not come off even if force is applied from either the left or right direction, and the gutter will not come off. can be firmly fixed.
