BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden hole filling member for closing a decorative hole formed in a joint between different materials.

[0002]

2. Description of the Related Art The above-mentioned deck, veranda,
In structures such as pavements, floorboards, handrails, pillars, wooden playground equipment, bridges, piers, and timber constructions, locking members such as bolts are usually used for connecting wood or connecting different materials such as wood and steel. Is used. Such a locking member,
In general, the material is inserted into a connection hole formed in a connection portion of the material and fastened with a nut.

[0005] FIG. 5 is a partially cutaway perspective view illustrating a joint portion between a floor plate and a joist, which is mentioned as an example of joining a structure mainly composed of wood as described above. As shown in this figure, the first material (floor board) M1 is provided with a first connecting hole H1, and the second material (joist) M2 is provided with a second connecting hole H2. A coupling hole H is formed in this state, and a bolt B as a locking means is inserted into the coupling hole H, and the two are coupled by being fastened with a nut N.

[0004] In particular, the first coupling hole H1 is provided in two stages: a small hole corresponding to the diameter of the body of the bolt B and a large hole corresponding to the diameter of the head of the bolt B thereon. The first material M1 and the second material M2 are connected by the bolt B, and the head of the bolt B is in a state of entering the inside of the large hole.

[0005] A wooden cylindrical hole-filling member 1 'is fitted into the entrance of the first coupling hole H1 in which the head of the bolt B is fitted, and the surface of the hole-filling member 1' is made of a first material M1. It is flush with the surface. By doing so, since the head of the bolt B is not exposed on the surface of the first material M1, the appearance is beautiful and a favorable landscape is obtained.

[0006] In addition to the above, there is a case where a caulking agent made of putty or synthetic resin is filled in the bonding hole to fill the hole.

[0007]

By the way, the conventional FIG.
Is typically manufactured by cutting a columnar rod into a cut end, and such cut end filling member 1 'is fitted into a joint hole of a first material M1 such as a floor plate. Have been. Therefore, since the direction of the grain is different between the first material M1 and the hole filling member 1 ', the expansion rate and the shrinkage rate in the same direction due to moisture absorption or a change in air temperature are different between the two, so that the two materials have not been A gap is formed between them. Once the gap is formed, the wooden hole-filling member 1 'weathers as the years pass, causing a so-called slimming phenomenon in which the diameter of the member becomes small, and the wooden hole-filling member 1' comes out of the connecting hole.

[0008] Even if it does not come off, the filling member 1 '
A gap is formed between the outer peripheral surface of the first hole H1 and the inner peripheral surface of the first coupling hole H1.
Disadvantageously corrodes the surface.

This applies to the case where the caulking agent is filled, and the generation of the above-mentioned gap cannot be effectively suppressed because the caulking material solidifies and loses its volume in many months.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is easy to mount, and can effectively suppress the generation of a gap.
It is an object of the present invention to provide a wooden hole filling member that is flush with the surroundings when mounted.

[0011]

According to a first aspect of the present invention, there is provided a hole filling member for wood having a diameter larger than that of a connection hole provided on an entrance side of a connection hole for a locking member provided at a connection portion of wood. And a hole filling member for wood that has an inner peripheral surface fitted into a smooth decorative hole and covers the locking member, and is formed on a cylindrical member main body having a head and an outer peripheral surface of the member main body. ,
The head has a plurality of annular projections having a diameter slightly larger than the diameter of the decorative hole, and the head has a flat upper surface and a diameter that can be pressed into the decorative hole. A concave portion for fitting the head of the locking member is recessed on the bottom surface of the member main body, the member main body is formed of a rigid material, and the annular protrusion is formed of a resilient material. It is characterized by being formed.

[0012]

According to the first aspect of the present invention, the diameter of the annular projection of the filling member is set slightly larger than the diameter of the decorative hole. After inserting the locking member into the formed coupling hole and fastening, the hole filling member is pressed into the decorative hole, so that there is no gap between the outer peripheral surface of the annular projection and the inner peripheral surface of the decorative hole. Accordingly, intrusion of rainwater or the like into the connection hole through the makeup hole is suppressed.

Further, since a space is formed between the annular projections in a state where the filling member is mounted in the decorative hole, the space serves as a buffer, and rainwater or the like accumulates in the buffer, so that the water flows directly into the connection hole. Penetration is effectively prevented, so that corrosion of the locking means can be prevented. Furthermore, the head of the member main body can be flush with the surface of the wood in a state where the head is pressed into the decorative hole, and when a floor plate or the like is used as the wood, there is an inconvenience due to the presence of unevenness in the floor plate. That is, it is possible to avoid inconveniences such as difficulty in walking on the floorboard and in which furniture and the like cannot be normally placed.

Further, since a concave portion for fitting the head of the locking member is formed in the bottom surface of the member main body, the concave portion is fixed to the head of the locking member when the filling member is fitted in the decorative hole. The lower end edge portion abuts on the step portion at the back of the coupling hole, so that the embedding depth of the filling member can be made constant without being affected by the thickness of the head of the locking member. As a result, the surface of the material and the surface of the filling member can be easily set to a flush state.

Further, the member main body is formed of a rigid material, and the annular projection is formed of an elastic material. When the filling member is press-fitted into the coupling hole, the annular projection forms the rigid member main body. The core is elastically deformed and compressed, and is easily fitted to a preset depth. In addition, since the hole filling member is fitted into the decorative hole with the outer peripheral surface of the annular projection pressing the inner peripheral surface of the decorative hole, no gap is formed between the annular protrusion and the inner peripheral surface of the decorative hole. Infiltration of rainwater or the like into the connection hole is effectively suppressed.

As described above, the wood hole filling member of the present invention has a cylindrical member body and a plurality of members formed on the outer peripheral surface of the member body and having a diameter slightly larger than the decorative hole. Because it consists of a ring-shaped projection,
After inserting the fastening member into the joint hole drilled in the joint part of the wood and fastening it, the hole filling member is pressed into the decorative hole, so that between the outer peripheral surface of the annular projection and the inner peripheral surface of the decorative hole. Has no gap at all, and it is thereby possible to reliably prevent infiltration of rainwater or the like into the coupling hole through the cosmetic hole.

Further, since a space is formed between the annular projections in a state where the filling member is mounted in the decorative hole, the space serves as a buffer, and rainwater or the like accumulates in the buffer. Penetration is effectively prevented, so that corrosion of the locking means can be prevented, which is advantageous in extending the useful life of the wood. Furthermore, since the head of the member can be flush with the surface of the wood in a state in which the member is inserted into the decorative hole, when the wood is a floorboard or the like, it is difficult to walk due to the unevenness of the floorboard. It is possible to avoid such inconvenience that the furniture or the like cannot be normally arranged on the floorboard.

A recess for fitting the head of the locking member is formed in the bottom surface of the member body of the hole filling member, and the depth of the recess is made substantially larger than the thickness of the head of the locking member. If the concave portion surrounds the head of the locking member while the filling member is fitted in the coupling hole, the lower end edge thereof abuts the step at the back of the coupling hole so that the locking member is engaged. The filling depth of the filling member can be made constant without being affected by the thickness of the head, and as a result, the surface of the material and the surface of the filling member can be easily set to the same state.

Further, if the member main body of the filling member is formed of a material having rigidity and the annular protrusion is formed of a material having elasticity, when the filling member is pressed into the coupling hole, the annular protrusion has rigidity. The member body is used as a core and elastically deformed and compressed, so that the annular projection can be easily fitted to a predetermined depth of the decorative hole. In addition, since the hole filling member is fitted into the decorative hole with the outer peripheral surface of the annular projection pressing the inner peripheral surface of the decorative hole, no gap is formed between the annular protrusion and the inner peripheral surface of the decorative hole. Intrusion of rainwater or the like into the connection hole can be reliably prevented.
