Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a gutter support used for attaching eaves gutters.

(Prior Art) As a conventional gutter support, one shown in FIG. 4 is known.

In this conventional gutter support, a protrusion 02 is formed on the front surface of a fixed plate 01, and a leaf spring 04 is provided at a position facing the protrusion 02 on the lower surface of the proximal end of a support arm 03. Therefore, the rear ear part 05 of the eaves gutter is received and supported from below, and the leaf spring 04 presses the rear ear part 05 from the front to prevent the ear part from falling off.

(Problem to be solved by the invention) However, in such a conventional gutter support, the rear ear part 05 of the eaves gutter cannot freely move back and forth between the protrusion 02 and the leaf spring 04. Therefore, the leaf spring 04 comes into contact with the rear ear part 05 and receives the load of the eaves gutter every time the eaves gutter receives an updraft or impact. Therefore, the fatigue of the leaf spring 04 is large,
Especially in the case of gutter supports that are integrally molded with resin.
There was a problem in that the leaf spring 04 could develop cracks from the base and fall off.

(Means for solving the problem) The present invention was made with the purpose of solving the above-mentioned problems. a plate; a support arm protruding from the front surface of the mounting plate;
A receiving part for receiving the rear ear part of the eave gutter is provided on the front surface of the mounting plate, and a plate for preventing the rear ear part from falling off is provided on the lower surface of the base end of the support arm and in front of the receiving part. In the gutter support provided with a spring, a diagonally upper position of the receiving portion on the lower surface of the proximal end of the support arm is formed as a stopper surface that restricts forward movement of the rear ear portion, and the stopper surface is formed on a plate. The means is placed closer to the mounting plate than the tip of the spring.

(Function) In the gutter support of the present invention, the rear ear portion of the eaves gutter is received and supported from below by the receiving portion of the mounting plate. In the supported state, the stopper surface usually restricts the forward movement of the rear ear, and the tip of the leaf spring of the support arm is separated from the rear ear, so that it is not receiving any load from the eaves gutter, and the eaves gutter is exposed to the wind blowing up. Only when the rear ear slips off the stopper surface due to blowing or impact, or when the area around the rear ear of the eaves gutter curves and deforms, the leaf spring receives the load from the rear ear and prevents it from falling off. Demonstrate function.

(Example) Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

First, the configuration of the embodiment shown in FIGS. 1 to 3 will be described.

The gutter support A of this embodiment includes a mounting plate 10 that is attached to a fixed surface 2 such as a pillar or a wall with screws 1 in abutting state, and a support arm 20 that projects forward from the top of the mounting plate 10. and the mounting plate 10.
and the support arm 20, for example, is made of about 40% glass fiber.
It is integrally molded from synthetic resin such as polycarbonate resin, vinyl chloride resin, and ABS resin.

The mounting plate 10 is provided with a rear protrusion 11 that receives and supports the rear ear part 31 of the eaves gutter 3 from below at a lower position of the base end of the support arm 20, and a rear protrusion 11 that receives and supports the rear ear part 31 of the eaves gutter 3 from below. Nail holes 12 are opened at both sides of the part.

The support arm 20 is tapered in a substantially horizontal direction, and the lower surface of the base end thereof is formed into a rearwardly inclined surface. A front protrusion 21 that supports the front ear part 32 of the eaves gutter 3 is formed at the tip of the support arm 20, and a leaf spring 22 is provided at the lower surface of the base end and in front of the rear protrusion 11 of the mounting plate 10. is established,
Further, a stopper surface 23 is vertically formed by a step at a position diagonally above the rear projection 11 on the lower surface of the base end.

The stopper surface 23 is for restricting the forward movement of the rear ear portion 31 in the supported state by the rear protrusion 11.
2 is disposed closer to the mounting plate 10 than the tip.
That is, in the horizontal direction, the distance a between the stopper surface 23 and the rear projection 11 is narrower than the distance b between the tip of the leaf spring 22 and the rear projection 11.

Further, the substantial distance c between the stopper surface 23 and the rear protrusion 11 is formed to be larger than the width d of the rear ear portion 31 of the eaves gutter 3.

Furthermore, the leaf spring 22 has its tip and rear projection 1
1 is formed to a length that is narrower than the width d of the rear ear portion 31 of the eave gutter 3 (see FIG. 3).

Next, the operation of the embodiment will be explained.

First, the front ear part 32 of the eaves gutter 3 is formed in a groove shape that opens to the rear side, and the front ear part 32 is supported by the front protrusion 21 of the support arm 20 in a locked state.

Next, the rear ear part 31 is formed in a hollow shape, and the rear ear part 31 is inserted between the rear protrusion 11 of the mounting plate 10 and the leaf spring 22 of the support arm 20 so that the leaf spring 22 is elastically inserted. By pushing up the upper part of the rear wall 33 of the eaves gutter 3 and the rear ear part 31 while curving it in the direction of the mounting plate 10 while deforming it, the rear ear part 31 is attached to the rear projection 11 and the stopper surface 23 of the support arm 20. is locked and supported.

In this supported state, the forward movement of the rear ear portion 31 is usually restricted by the stopper surface 23 of the support arm 20, as shown in FIG. That is, the tip of the leaf spring 22 of the support arm 20 and the rear ear part 31 are spaced apart, and the leaf spring 22 does not receive any load from the eave gutter 3. The leaf spring 11 is activated for the first time when the rear ear part 31 of the eaves gutter 3 slips off the stopper surface 23 due to blowing up wind or receives an impact, or when the vicinity of the rear ear part 31 of the eaves gutter 3 is deformed in a curved manner. It receives the load of the rear ear part 31, and exhibits a falling-off prevention function.

Therefore, the leaf spring 22 has reduced fatigue and improved durability compared to the conventional structure in which the leaf spring 22 is constantly subjected to the load from the eave gutter 3.

Note that even after the rear ear portion 31 has slipped from the stopper surface 23, it can be returned to the normal supported state in which forward movement is regulated by the stopper surface 23 by simply pushing it up again.

Although the embodiments of the present invention have been described above in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and any design changes or the like that do not depart from the gist of the present invention are included in the present invention. It can be done.

For example, the support arm is not limited to a tapered shape;
In addition, there is no need to form the stopper surface with a step,
The inclined surface on the lower surface of the base end may be used as the stopper surface.

Further, the support structure for supporting the front ear portion of the eaves gutter is not limited to the embodiment, and may be a structure using a leaf spring.

(Effects of the invention) As explained above, in the gutter support of the present invention, the leaf spring does not move under the eave in the normal state where the stopper surface restricts the forward movement of the rear ear part of the eaves gutter. Since the leaf spring does not receive any load from the gutter and only receives the load when the restriction on movement of the rear ear by the stopper surface is released, the leaf spring has the effect of reducing fatigue and improving durability.
