Description

[Detailed explanation of the idea] (Industrial application field) This invention relates to eaves gutters.

(Prior art) Traditionally, eaves gutters have been widely used to have a roughly U-shaped or semicircular cross-section, and when these eaves gutters are installed along the eaves, they have a shape that corresponds to the cross-sectional shape. The outer bottom of the eaves gutter is held by the mounting bracket.

However, such a mounting structure has problems in that the mounting metal fittings are exposed to the outside, making them unsightly, and also causing damage to the appearance due to the occurrence of rust.

For this reason, for example, as described in Japanese Utility Model Publication No. 55-29620, a rectangular cylinder-shaped edge facing inward is integrally molded on the opening edge of the eaves gutter made of a synthetic resin molded product. It has a structure in which hanging pieces protrude from the lower ends of the opposing inner surfaces of the edges, and both ends of the mounting bracket are secured to the lower walls of both edges that protrude horizontally from the inner surfaces of the opening end of the eaves gutter. An eaves gutter has been devised in which the parts are brought into contact with each other from below, and suspended with a hanging piece preventing the part from coming off.

(Problem to be solved by the invention) According to the eaves gutter having such a structure, the mounting brackets are not exposed to the outside, but the mounting brackets are not exposed to the outside, but the side edges of the rectangular tube shape that are received by the locking parts at both ends are Because the lower surface is relatively wide and extends horizontally from the inner surface of the wall facing the eaves gutter, the eaves gutter and the mounting bracket may move in the direction of misalignment (in the width direction of the eaves gutter), resulting in insufficient mounting strength. It becomes stable, and there is a risk that the locking part of the mounting bracket may come off the hanging piece due to wind pressure or the like.

In addition, since the lower surfaces of the above-mentioned both side edges are formed with a straight cross section and protrude from the inner surface of the opposing wall of the eaves gutter, a large bending action occurs on the lower surface due to the load applied to the eaves gutter, causing the lower surface to bend. There is a problem in that the opposing wall surface of the eaves gutter that protrudes from the roof no longer has sufficient strength.

Furthermore, eaves gutters made of synthetic resin moldings are susceptible to deterioration due to sunlight, and as mentioned above, the walls of eaves gutters that directly support the load are exposed to sunlight. If it deteriorates, the load will cause that part to break in a short period of time.

The present invention was developed in view of these problems, and it is possible to stably and reliably support the product with the mounting bracket, and increase the rigidity of the mounting part to increase load capacity, so that it can be used for a long period of time. The purpose of this invention is to provide an eaves gutter that exhibits a predetermined installation strength.

(Means for solving the problem) In order to achieve the above purpose, the eaves gutter of the present invention:
Rectangular tube portions are formed at the upper end edges of both front and rear walls of the gutter body made of a synthetic resin molded product, and at least the lower half of the inner surface of the front square tube portion of these square tube portions and the lower half thereof An upper wall, a rising wall, and a lower wall are respectively formed by recessing the inner part of the bottom surface connected to the square cylinder part into an inverted L-shape, and from the inner end of the upper wall, a wall shorter than the rising wall is formed. The gutter has a structure in which a hanging piece is extended, and the hanging piece, the upper wall, the rising wall, and the lower wall form an engagement groove for a mounting fitting that opens inside the gutter body.

(Function) The gutter body is supported by making the engaging piece of the eaves gutter mounting bracket having the upright engaging piece contact and lock with the lower surface of the square tube portion on the front side of the gutter body.

The upper wall and the rising wall of the engagement groove into which the engagement piece of the mounting bracket is inserted and locked are at least the inner corner of the front and rear corner tube portions forming the edges of the gutter body. Since it is recessed in an inverted L shape, the width of the upper wall against which the engagement piece of the mounting bracket comes into contact is small, and the engagement piece can be accurately positioned with almost no misalignment between the upright wall and the hanging piece. This allows for stable installation.

In addition, since the part that supports the load on the eaves gutter is formed into an L-shaped section by the upper wall and the rising wall, the bending rigidity is large and the load resistance is increased, and the eaves gutter is The load applied to the can be firmly supported through the mounting fittings.

Furthermore, these upper walls and rising walls are recessed within the square tube part and are covered by the upper wall and outer wall of the square tube part, so they do not receive sunlight directly and are exposed to light. It prevents deterioration caused by damage and maintains the specified mounting strength over a long period of time.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

In FIG. 1, the eaves gutter, generally indicated by the reference numeral 1, is composed of a gutter body 2 made of a synthetic resin molded product with a substantially U-shaped cross section. Hollow square tube parts 3a and 3b extending in the length direction are formed at the upper end edges of 21a and 21b, respectively, and these front and rear square tube parts 3a,
The lower half part of the opposing inner surface of 3b and the inner part of the bottom surface continuous to the lower half part are recessed into the rectangular tube part in an inverted L shape to form upper walls 32a, 32b and rising walls 31a, 31b, respectively. , hanging pieces 33a, 33b extend downward from the inner ends of the upper walls 32a, 32b.

Further, in the square tube part 3a on the front side, a part of the bottom wall part is formed into a lower wall 34a that extends inward from the lower end of the rising wall 31a and continues to the upper end of the side wall 21a, and this lower wall 34a and the rising wall 31a, an upper wall 32a, and a hanging piece 33a, forming a space surrounded by the engaging groove 4a, and opening inward of the eave body 2 between the ends of the hanging piece 33a and the lower wall 34a. It is formed at the insertion opening of the mounting bracket 5.

Further, in the rear square tube portion 3b, a space surrounded by the rising wall 31b, the upper wall 32b, and the hanging piece 33b is formed into an engaging groove 4b having a downward opening. In addition, in the figure, 22a and 22b are
These are reinforcing protrusions formed on the inner surfaces of the bent portions on both sides of the bottom of the gutter body 2.

On the other hand, a mounting bracket 5 for attaching the eaves gutter 1 to the eaves
is composed of a locking rod 51 that fits between the both side walls 21a and 21b of the gutter body 2, and a mounting rod 52 connected to the approximate center of the locking rod 51, and one end of the locking rod 51 An engaging piece 51a that fits into the engaging groove 4a and brings the tip of the engaging piece 51a into contact with the lower surface of the upper wall 32a is bent diagonally upward at the portion,
At the other end, an engaging piece 51b is formed which is bent into an L-shape so as to extend below the hanging piece 33b and then bent diagonally upward.

Further, the mounting rod 52 is formed by rising upward from the connection point to the locking rod 51, then bending in the horizontal direction, and then bending downward, and is configured such that this downwardly directed portion is fixed later. ing.

In addition, in the figure, 53a and 53b are plate springs extending from the locking rod 51 so as to press against the upper end of the eaves gutter 1, substantially the upper wall surface of the square tube parts 3a and 2b. This prevents the surface from lifting up.

In the above configuration, in order to attach the eaves gutter 1 to the mounting bracket 5, the hanging piece 3 that forms the engagement groove 4b of the square tube portion 3b on the rear side wall 21b of the eaves gutter 1

After placing the leaf spring 5 in the corresponding position between the
When 3b is pushed up and then pushed diagonally downward, the engagement piece 51b will fit into and engage with the engagement groove 4b.

Next, move the front side wall 21a of the gutter body 2 along the arrow B.
When pushed up in the direction, one engaging piece 51a of the mounting bracket 5 pushes open the side wall 21a while sliding on the inner wall surface of the square tube part 3a, and when it comes off from the tip of the hanging piece 33a, the side wall 21a returns to its original state. At the same time when it is restored and the engagement piece 51a fits into and locks into the engagement groove 4a,
The eaves gutter 1 is supported by the mounting bracket 5 with the leaf spring 53a in pressure contact with the upper wall surface of the square tube portion 3a.

In this state, the eaves gutter 1 is supported by the engaging pieces 51a, 51b of the locking rod 51 that are in contact with the lower surfaces of the upper walls 32a, 32b of the square tube parts 3a, 3b, and the engaging pieces 51a , 51b are the engagement grooves 4a, 4

The cross-sectional shape may also be formed into a semicircular shape.
Further, the front and rear square tube portions 3a and 3b may have the same cross-sectional shape.

(Effects of the invention) As described above, according to the eaves gutter of the present invention, at least the front square tubular portion forming the upper end edges of both front and rear walls of the gutter body made of a synthetic resin molded product. The lower half of the inner surface and the inner side of the bottom connected to the lower half are recessed into the rectangular tube part in an inverted L shape to form an upper wall, a rising wall, and a lower wall, respectively. A hanging piece that is shorter than the standing wall is extended downward from the inner end, and this hanging piece, the upper wall, the standing wall, and the lower wall form an engagement groove for a mounting bracket that opens inside the eave body. Because it has a structure of
Therefore, the engagement piece of the locking rod can be accurately engaged with the upright wall and the hanging piece with almost no deviation, and stable attachment is possible.

In addition, the upper wall of the engagement groove, which receives the load of the eaves gutter, is connected to the bottom wall of the rectangular tube part through the rising wall, and the overall shape is inverted L-shape, so the bending rigidity is increased. As the size increases, the load capacity increases, and the load applied to the eaves gutter can be firmly supported through the mounting fittings.

Furthermore, these upper walls and rising walls are recessed within the square tube part and are covered by the upper wall and outer wall of the square tube part, so they do not receive sunlight directly and are exposed to light. It is possible to maintain a predetermined strength over a long period of time by preventing deterioration due to Therefore, the upper wall supported by the engagement piece of the mounting bracket always maintains a constant load capacity even though it is subjected to the load of the eaves gutter, and can maintain mounting strength over a long period of time.
