Description

  The present invention relates to an eaves hook support, and more particularly to an eaves hook support mounting structure that supports the eaves in a suspended manner by locking the front and rear ears of the eaves.

  For example, the hanging eaves support shown in FIG. 7 is used as an eaves support used when 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. 7 of the present application, a known eaves support C includes a mounting portion 1a whose main body is attached to a surface to be mounted 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 the eaves supported by being suspended from the eaves support as described above, one formed from an elastic synthetic resin is preferably used. For example, the eaves main body is made of a resin material such as polycarbonate resin or ABS resin. In this case, the front ear portion and the rear ear portion are integrally molded.

  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), which is a type of), moves to the surface side of the coating layer. There is a problem that the mounting portion itself is deteriorated (stress crack) by moving to the surface side of the mounting portion and penetrating.

  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, An eaves support that can maintain excellent quality characteristics for a long time without the deterioration of the mechanical strength due to the plasticizer is disclosed in the mounting portion of the eaves support made of polycarbonate resin.

As shown in a side view in FIG. 8 of the present application, the eaves support B is in contact with the back surface of the mounting portion 1a of the known eaves support C shown in FIG. 7, that is, the mounting surface of the mounting portion 1a. The prevention layer 4a for preventing the migration of the plasticizer is provided on the surface, and when the eaves support is made of a polycarbonate resin, the prevention layer is a hard vinyl chloride resin layer that does not contain the plasticizer. It is described as 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. The present invention has been made in view of the above-described background art, and its purpose is to prevent the plasticizer from being transferred from the mounting surface to the mounting portion of the eaves-supporting device in a cost-effective manner with a simple process. At the same time, it is an object to provide an eaves bar support mounting structure in which fixing means such as screws are temporarily fixed and the eaves bar support can be fixed to the mounting surface with good workability.

In order to solve the above-mentioned problems, an eaves rod support mounting structure according to the first aspect of the present invention is an eaves rod support made of synthetic resin, and the main body of the eaves rod support is attached to a surface to be mounted. The base is composed of a mounting base to be worn and a supporting part for supporting the eaves rod in a suspended manner, and an insertion hole is formed in the mounting base, and an inner surface of the insertion hole forms the eaves support. It is characterized in that the holding force of the mounting screws is improved by lining molding with a functional resin different from the resin to form screw holes.

The invention of claim 1 further together constitute a synthetic resin that is capable of preventing the migration of plasticizer from the mounting surface of the above functional resin, an attached surface side of the lining part from the insertion hole It is characterized in that a protruding protrusion is formed.

The invention of claim 1 is further characterized by a less than twice the molding shrinkage of the functional resin lining the inner surface of the insertion hole on the molding shrinkage of the base synthetic resin.

In the invention described in claim 2 of the present application, in the eaves-rod support mounting structure described in claim 1 above, the ring portion protruding inwardly around the screw hole entrance portion of the functional resin lining the inner surface of the insertion hole is provided around the periphery. It is characterized by being established.

In the eaves rod support mounting structure according to the first aspect of the present invention, the main body of the eaves rod support includes an attachment base attached to the surface to be mounted and a support portion for supporting the eaves rod suspended. The mounting base is provided with an insertion hole, and the inner surface of the insertion hole is lining- molded with a functional resin different from the base synthetic resin forming the eaves-holding support and is formed into a screw hole. The holding force of the mounting screw is improved, and the eaves support can be firmly fixed to the mounted surface by screwing the mounting base to the mounted surface such as the nose plate of the eaves.

In the eaves brace support mounting structure according to the first aspect of the present invention, the functional resin is further capable of preventing the migration of the plasticizer from the mounting surface, and the lining portion is mounted. Since the surface side protrudes from the insertion hole to form a protruding protrusion, the protruding protrusion prevents the mounting surface and the back surface of the mounting base from coming into direct contact with each other, and a plasticizer is applied to the mounting base. It is possible to prevent migration and deterioration.

In the eaves brace support mounting structure according to the first aspect of the present invention, the molding shrinkage of the functional resin lining the inner surface of the insertion hole is not more than twice the molding shrinkage of the base synthetic resin. By doing so, the adhesiveness is improved when the functional resin is inserted into the insertion hole formed in the base synthetic resin and the lining molding is performed, and the occurrence of detachment or floating after molding is prevented.

In the eaves guard support mounting structure according to the invention of claim 2 of the present application, in particular, a ring portion protruding inwardly is provided around the screw hole entrance portion of the functional resin lining the inner surface of the insertion hole. Therefore, this ring part functions as a temporary fixing part of the mounting screw when the mounting screw is screwed into the mounting surface with an electric drill or the like, and the mounting base is attached to the nose plate etc. with good workability. Screws can be fixed to the surface.
