Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves gutter having a cosmetic property and a solid feeling. 2. Description of the Related Art Conventionally, eaves gutters having a semicircular or square cross section have been used for roof eaves. For a more beautiful finish, see, for example,
An eaves gutter formed so that the middle of the front side of an eaves gutter main body protrudes forward, as described in Japanese Patent Application Publication No. 04 and Japanese Utility Model Publication No. 3-76934. As shown in FIG. 3, for example, the above-mentioned conventional eaves gutter includes a bottom wall b of an eaves gutter main body a front wall c and a rear wall d continuous with the front and rear sides of the bottom b. Are provided, and locking ears e and f are formed at upper end portions of the front wall portion c and the rear wall portion d, respectively. Further, the front wall portion c is formed to be inclined in a curved shape so as to protrude downward and forward, and a lower end of the front wall portion c has a front corner g bent downward at an acute angle.
Are formed. A bottom wall portion b continuing to the front corner g has an inclined surface h extending so as to incline rearward and upward from the front corner g, and curves downward and rearward from the rear end of the inclined surface h. And a curved surface portion i extending to the side. The above-mentioned eaves gutter is used by being suspended and supported by an eaves gutter hanging member k fixed to an eaves j. At this time, a locking ear portion of a front wall c of an eaves gutter main body a is used. e is locked by an engaging portion m bent upward at the front end of the eave gutter hanging device k,
On the other hand, the eaves gutter body a is locked and supported by a locking ear n at the rear end. Accordingly, when the eaves gutter suspended and supported by the eaves j is viewed from below the eaves, a front wall portion c formed to be curved and inclined so as to protrude downward and forward of the eaves gutter body a, and a curved surface portion. i
And the bottom wall portion b having the shape makes the eaves design more beautiful. However, in the conventional eaves gutter, if the bottom wall b and the front wall c of the eaves gutter body a are formed in a wide shape, the design is further improved. Distortions such as undulations and undulations are visible on the outer surfaces of the wall portion b and the front wall portion c, and there is a problem that appearance is unsightly. Therefore, if the wall thickness of the eaves gutter body a is increased, distortion such as undulation and waving is reduced, but there is a problem that the eaves gutter becomes heavy and the amount of resin is increased, resulting in an increase in cost. . In view of such circumstances, the present invention is intended to make the eaves gutter body having cosmeticity and solid feeling less noticeable, such as undulation and waving, so that the bottom wall portion and the front wall which stand out most from the bottom can be seen. The purpose is to provide eaves gutters with increased wall rigidity. [0010] In order to achieve such an object, the eaves gutter of the present invention is provided on the outer peripheral surface of the front wall and the bottom wall of the eaves gutter main body with the longitudinal direction of the eaves gutter main body. A plurality of protrusions formed of hollow ribs continuous in the direction are provided to form an uneven surface. In the eaves gutter of the present invention, the material and the processing method are not particularly limited, and examples thereof include a material obtained by melting a synthetic resin and extruding it into a gutter shape by extrusion molding. In the eaves gutter of the present invention, when used by being attached to the eaves gutter, hollow ribs are formed on the outer peripheral surfaces of the front wall portion and the bottom wall portion of the eaves gutter main body in the longitudinal direction of the eaves gutter main body. Since the projections are provided with a plurality of projections and an uneven surface is formed, the rigidity of the bottom wall and the front wall that stand out from the bottom rises, and the eaves gutter main body that has cosmeticity and solid feeling is wavy and wavy Distortion becomes less noticeable. Furthermore, since the projection is a hollow rib, the amount of resin is small, and the eaves gutter is reduced in weight. Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a partially cutaway perspective view showing an embodiment of the eaves gutter of the present invention. In FIG. 1, reference numeral 1 denotes an eaves gutter main body. The eaves gutter main body 1 comprises a front wall portion 2 on the outdoor side, a rear wall portion 3 on the indoor side, and a bottom wall portion 4. Reference numeral 5 denotes an ear on the outdoor side provided above the front wall 2 on the outdoor side. Reference numeral 6 denotes an ear on the indoor side provided above the rear wall 3 on the indoor side. The front wall 2 is formed so as to be inclined outward so as to protrude downward and forward, and a lower corner of the front wall 2 has a front corner 20 which is bent downward at an acute angle. Have been. Further, the bottom wall portion 4 continuing to the front corner 20 has an inclined surface portion 21 extending so as to incline rearward and upward from the front corner 20 and outwardly downward and rearward from the rear end of the inclined surface portion 21. Curved surface portion 22 extended to be curved
And On the outer peripheral surfaces of the bottom wall portion 4 and the front wall portion 2, a plurality of projections 7 are provided which are continuous in the longitudinal direction of the eaves gutter main body 1, and the projections 7 and 8 have hollow portions 7 therein. Are formed to form hollow ribs and form streaky uneven surfaces. Next, a method of using the eaves gutter will be described with reference to FIG. First, the mounting position of the eaves gutter hanging tool 11 is determined on the nose cover plate 10 of the eaves gutter, and the eaves gutter mounting part 1 of the eaves gutter hanging tool 11 is determined.
Insert the nail 13 into the mounting hole 2 and insert the nail 13
To fix the eave gutter hanging tool 11 to the tip of the eave. Subsequently, the outdoor ear 5 of the eave gutter is fitted into the outdoor ear holding portion 15 of the eave gutter supporting arm 14 which is bent and projected from the eave tip mounting portion 12 toward the outdoor. Finally, the inner ear 6 of the eave gutter is inserted into the inner ear holding portion 16 of the eave gutter support arm 14, and the eave gutter support arm 14 of the eave gutter hanging tool 11 is inserted.
Attach the eaves gutter. By doing so, the front wall 2 of the eaves gutter main body 1
Since the rigidity of the bottom wall 4 is increased by the projections 7 formed of hollow ribs, distortion such as undulation is prevented. Even if the front wall 2 and the bottom wall 4 are distorted,
Distortion becomes less noticeable due to the uneven surface formed by the plurality of projections 7, and when attached to the eaves of the roof, the design becomes more excellent in decorativeness and solidness. Although the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to this embodiment, and even if there is a design change or the like within a range not departing from the gist of the present invention. Included in the invention. For example, in the above embodiment, the cross-sectional shape of the projection 7 made of a hollow rib is square, but may be triangular. The projections 7 formed on the front wall 2 and the bottom wall 3 may have different sizes and shapes. According to the eaves gutter of the present invention, a plurality of projections formed of hollow ribs extending in the longitudinal direction of the eaves gutter main body are provided on the outer peripheral surfaces of the front wall portion and the bottom wall portion of the eaves gutter main body. The unevenness is formed, so the rigidity of the bottom wall and the front wall, which stand out most from the bottom, increases, so that distortion such as undulation and waving of the eaves gutter main body is not noticeable, making the eaves design beautiful . Further, since the projections are hollow ribs, the amount of resin is small, and the eaves gutter is reduced in weight, so that transportation and mounting work can be performed easily.
