Description

  The present invention relates to an eaves hook support, and more particularly to an eaves hook support attachment structure that supports the eaves by a hanging method by locking the front and rear ears of the eaves.

  For example, the hanging eaves support shown in FIG. 8 is used as an eaves support for attaching various rain gutters, for example, eaves, to a mounting surface such as a pillar or wall of a building, or a nose cover. Are known. That is, as shown in FIG. 8 of the present application, the known eaves support D includes a mounting portion 1a whose main body is attached to a mounting surface and a support portion 2a that supports the eaves, A front ear support portion 21a that supports the front ear portion on the outdoor side of the eaves is provided at the tip.

  On the other hand, a leaf spring piece 23a protrudes from the lower surface portion 22a of the support portion 2a, and a locking piece 11a is formed on the outdoor side of the mounting portion 1a so as to be inclined upward. The stop piece 11a is suspended and supported so as to sandwich the rear ear portion which is the indoor side of the eaves. In this way, the eaves is attached to a mounting surface such as a nose cover plate of the eaves. A plurality of screw holes 3a are inserted into the mounting portion 1a, and are firmly fixed to the mounting surface by a fixing tool such as a nail or a screw.

  As described above, the eaves supported by being suspended from the eaves support is preferably made of a synthetic resin having elasticity, such as hard polyvinyl chloride resin, polycarbonate resin, ABS resin, etc. What integrally molded the eaves main body, the front ear part, and the rear ear part from the resin material is used.

  When the above-described attached surface, for example, a nose cover plate is made of wood, the surface is often covered with a metal cover in terms of fire prevention measures and aesthetics. As this metal cover, a decorative steel plate is used from the viewpoint of aesthetics. Usually, a decorative steel plate whose surface is covered with a vinyl chloride resin material, a so-called vinyl chloride steel plate, is used.

  However, when the surface of the nose cover plate to which the mounting portion of the eaves support is attached is covered with, for example, the above-mentioned vinyl chloride steel plate, DOP (dioctyl phthalate) contained in the vinyl chloride resin material which is this coating layer ), A plasticizer such as DEHP (di-2-ethylhexyl phthalate) is transferred to the surface side of the coating layer. Further, this plasticizer is used for eaves support made of polycarbonate resin or ABS resin, for example. If it moves to the surface side of the attachment portion and penetrates, there is a problem that the attachment portion itself deteriorates (stress cracks).

  In order to solve the above-described problem, Japanese Patent Application Laid-Open No. 09-165888 discloses that even if a decorative steel plate coated with a vinyl chloride resin material containing a plasticizer is attached to a surface to be attached such as a nose cover plate, There has been disclosed an eaves support which can maintain excellent quality characteristics for a long period of time without the mounting portion of the eaves support made of polycarbonate resin being subjected to the deterioration of mechanical strength due to the plasticizer.

As shown in FIG. 9 as a side view of the eaves support C, the eaves support supports are provided on the back surface of the mounting portion 1a of the known eaves support D shown in FIG. The surface to be in contact with the surface to be mounted is provided with a prevention layer 4a for preventing the migration of the plasticizer. When the eaves support is made of polycarbonate resin, the prevention layer is made of hard chloride containing no plasticizer. It is described that a vinyl resin layer is desirable. Specifically, it is stated that the prevention layer 4a made of hard vinyl chloride resin is integrally formed with a thickness of about 3 mm.
Japanese Patent Laid-Open No. 09-165888

  However, the eaves support described in Patent Document 1 must separately prepare a hard vinyl chloride resin that does not contain a plasticizer, and includes an attachment portion and a support portion, for example, made of polycarbonate resin. The eaves support body and the hard vinyl chloride resin must be integrally molded, which complicates the molding process and is not cost effective.
