ABSTRACT:

TECHNICAL FIELD
The present invention relates to a fastener, and more particularly to a fastener for fastening furniture, a desk, a shelf, or the like.
BACKGROUND ART
In offices and houses, furniture and equipment such as various housing shelves and desks are located. In such a situation, these furniture and equipment (hereinafter referred to as furniture) can move or fall down in case of an occurrence of quake such as earthquake.
In order to prevent the moving and falling down of the furniture as described above, the furniture should be fastened to the building.
Conventionally, the furniture is fastened by providing, for example, a fastener
101
as shown in
FIG. 11
in a suitable position in the portion where the furniture contacts with the building. The fastener
101
is generally formed by using metal because at least a certain strength is necessary for fastening the furniture. In the fastener
101
, threaded holes
102
are perforated.
FIG. 12
shows a state in which the furniture
110
is fastened to the building using the fastener
101
. In
FIG. 12
, the furniture
110
is fastened by providing the fastener
101
in a suitable position in the portion where the side
111
of the furniture contacts with the floor
120
of the building and driving screws
103
into the side
111
of the furniture and the floor
120
through the threaded holes
102
perforated through the fastener
101
(hereinafter referred to as “fastening to the floor”).
FIG. 13
also shows a state in which the furniture
110
is fastened to the building using the fastener
101
as in FIG.
12
. In
FIG. 13
, however, the furniture
110
is fastened by providing the fastener
101
in a suitable position in the portion where the top surface
112
(or a side) of the furniture contacts with the wall
130
of the building and driving the screws
103
into the top surface
112
(or the side) of the furniture and the wall
130
through the threaded holes
102
perforated through the fastener
101
(hereinafter referred to as “fastening to the wall”). The fastening to the wall as shown in
FIG. 13
is effective for fastening long narrow furniture.
In the case of fastening furniture using a fastener according to the prior art, however, the metallic fastener is visible from outside. Therefore, the metallic fastener looks bad and spoils the appearance in fastening wooden furniture. In addition, since the fastener is made of metal, the wooden furniture is easily flawed in fastening. Furthermore, the metal (the fastener) and the wood (the furniture) contact with each other in fastening the wooden furniture, so that sliding occurs easily.
SUMMARY OF THE INVENTION
In order to solve the above problems, it is an object of the present invention to provide a fastener that does not spoil the appearance of wooden furniture, does not make flaws easily, and does not cause sliding easily in fastening the wooden furniture.
In order to achieve the above object, the present invention provides a fastener having a predetermined shape, comprising a core plate member made of metal and a decorative member made of a wooden board covering the exposed portion of the core plate member. The decorative member includes a natural wood board, plywood, a synthetic, smoothly planed board, and the like. The natural wood board is most preferable.
In the fastener of the present invention, it is preferable that the decorative member made of the wooden board covers the entire core plate member.
In the fastener of the present invention, it is preferable that the decorative member is formed by using a wooden board whose central portion is hollowed out.
In the fastener of the present invention, it is preferable that the decorative member is formed by laminating wooden boards.
In the fastener of the present invention, it is preferable that the core plate member and the decorative member are integrated. The integration may be achieved by making the clearance between the hollow portion of the decorative member and the core plate member small or by adhesion of the core plate member to the decorative member.
In the fastener of the present invention, it is preferable that holes passing through the core plate member and the decorative member are formed.
In the fastener of the present invention, among the holes passing through the core plate member and the decorative member, the hole of the decorative member may be smaller than the hole of the core plate member.
In the fastener of the present invention, among the holes passing through the core plate member and the decorative member, the hole of the core plate member may be smaller than the hole of the decorative member.
Furthermore, the fastener may have any shape as long as the fastener is a material generally used as a fastener, for example, an L-type material, a T-type material, an I-type material, a flat L-type material, or a flat T-type material.
In the fastener, the core plate member made of metal may be one piece, the decorative member made of the wooden board may comprise a plurality of members, and the plurality of decorative members made of the wooden board may be integrated by adhesion.
Since the fastener according to the present invention is formed by covering the exposed portion of the core plate member made of metal with the decorative member made of the wooden board, the fastener has at least a certain strength. In addition, the decorative member serves as a cushioning material in fastening wooden furniture, so that the integrity of the furniture and the fastener in fastening the furniture improves. Furthermore, the fastener looks good and does not spoil the appearance of the furniture.
Furthermore, since the fastener according to the present invention is formed by containing the core plate member made of metal in the decorative member made of the wooden board, the fastener has at least a certain strength. In addition, the fastener does not spoil the appearance even when fastening wooden furniture. In the fastener according to the present invention, since the portion in contact with a side of the furniture (for fastening to the floor) or the top surface of the furniture (for fastening to the wall) is wood, the wood serves as a cushioning material. Therefore, flaws are not easily made. In the fastener according to the present invention, wood-to-wood contact is made between the fastener and furniture as described above. Therefore, sliding occurs less easily than in the case where metal-to-wood contact is made. Thus, a firmer fastening can be performed.
In the fastener according to the present invention, it is preferable that the decorative member is formed by using a wooden board whose central portion is hollowed out. According to the preferable example, a fastener that has a few bonding portions and provides a beautiful appearance can be obtained.
In the fastener according to the present invention, it is preferable that the decorative member is formed by laminating wooden boards. According to the preferable example, the decorative member can be formed by utilizing wood from thinning, waste wood or the like and by using members having a suitable size properly. Therefore, the decorative member can be formed relatively easily. Thus, cost reduction can be achieved.
In the fastener according to the present invention, it is preferable that the core plate member and the decorative member are integrated, that is, there is little or no clearance between them. According to the preferable example, there is little or no so called “play” between the core plate member and the decorative member. Therefore, a fastener that has at least a certain strength even when the decorative member made of a wooden board covers the core plate member made of metal can be obtained.
In the fastener according to the present invention, it is preferable that holes passing through the core plate member and the decorative member are formed and that the hole of the decorative member is smaller than the hole of the core plate member. According to the preferable example, the through-hole of the fastener is defined by the hole of the
