【発明の属する技術分野】
本発明は、釘の頭部の所定部位に緩衝部材を設け、釘止めする固定物に傷を付けずに釘打ちができること、又はこの際に、固定物の固止を確実にすること等を目的とした緩衝特性を備えた釘に関する。
【０００２】
【従来の技術】
従来、釘打ち時の緩衝と、固定物への損傷防止等を意図した方法としては、釘の頭及び／又は杭にパッキン、又は緩衝部材を設けた構成が知られている。例えば、特開平９−３２４８１１号の釘及びねじ、また実開昭６２−９６１１０号の釘、又は実開昭６３−５３４２９号のセメント系無機質建築板用釘等の文献がある。これらの文献は、単に釘の頭、杭等の適宜の部位に、緩衝部材を設けた構造であって、その緩衝効果は、必ずしも十分ではない、また釘の形状も特定されておらず、下記に説明する釘自体の問題もある等の如く、問題点が指摘されている。
【０００３】
前記の釘自体の問題点を説明すると、釘頭の平面中央部に平面長さ方向に添って若干の段付き部（盛上り部）を形成し、この段付き部をハンマー、自動釘打ち機等の打撃手段（以下、ハンマーで説明する）を利用して打っている。しかし、ハンマーを打付ける位置決めがないことから、釘の杭の芯より離れた位置を打つことが間々発生する。従って、杭に打付けの荷重が伝わらず、曲折することがあり、また頭の平面部も下方に曲がること等の弊害がある。そして、頭の平面部で固定側の物体（以下、物体とする）を固定するに際し、物体と頭とが面接触していているか否かを目視、又はこの両者間に間隔（隙間）があるか否かを目視することは、極めて困難である。それがために、再度打撃して物体の損傷を招くこと、又はこの損傷を回避するあまり隙間が発生したままで作業を終了し、欠陥問題の発生すること、又は規定（設計）上に基づく釘打ちができないこと等の弊害がある。
【０００４】
そして、この種の釘の改良案として、特開平８−２３２４０４の瓦固定釘がある。その内容は、槌打頭部を頭の隅部に形成し、この槌打頭部の下方に杭部を形成した構成であり、槌打頭部にかかる衝撃荷重を確実に杭部に伝えることを意図する。これにより、槌打頭部の折曲がり防止と、前述の課題解決を意図するものと考えられる。
【０００５】
しかし、この文献発明は、槌打頭部が杭の軸線上（方向）でなく、平面部の基部の一部から平面部の略中央部に至る構成であり、槌打頭部にかかる衝撃荷重を、確実かつスムーズに杭部に伝達するまでに至っていないのが現況である。
【０００６】
【発明が解決しようとする課題】
上記に鑑み、本発明は、断面形状が平面形状、丸形状、角形状でなる釘の頭部の平面部を、ハンマーで打った時に、当該平面部が曲折、破損等を回避する。そのための手段として、例えば、この平面部の最適箇所で、望ましくは、杭部の軸線上の相当位置部に、丸形、多角形等の任意形状の槌叩き部（突起部）を設ける。また物体の損傷防止のために、頭部の平面部に各種形態、又は弾力性、柔軟性等の特性を備えた緩衝部材を接着、差込み、緊締等に手段を利用して設ける。例えば、接着では、相手物体品と接触する位置部に接着剤、成形焼き付け等を利用して設ける。また差込みは、緩衝部材の筒部を、平面部に被嵌する。又は嵌合等に手段を利用して緊締する。尚、物体としては、陶器瓦、金属性瓦等として、その物体の損傷防止を目的とする。
【０００７】

【００１１】
【発明の実施の形態】
本発明の釘１の種類としては、図１〜図８に示した一例が好ましい構造である。以下、詳細に説明する。図１、図２は一般名称がセブン釘（１ａ）と称されており、杭部２と頭部３との構成であり、杭部２に抜け防止用の数個の突起２００と、周辺部に多数の切条２０１を有する。また頭部３には先端の折曲げ部３００を有し、平面部３０１に段差部３０２ａを介して段部３０２と、槌叩き部３０３とが設けられている。そして、この槌叩き部３０３は杭部２の軸芯線２ａに中心部を有する。これによって、釘１の打撃時に発生する荷重を確実かつスムーズに杭部２に伝わる構造とする。図中２０２は杭部２の上方端（頭部３を上にした状態における上方端）に設けた曲り部を示す。また２０３は杭部２の先端を示す。また図３、図４の例は、図１、図２の例と基本的な構造は略同じである。その相違点は、杭部２の構造であり、突起２００及び切条２０１に代り、ネジ２０４を設ける。さらに図５、図６の例は、図１、図２の例と基本的な構造は略同じである。その相違点は、釘１が一般名称のＬ釘（１ｂ）であること、及び杭部２の上方端をストレート部２０２ａとした構造にある。また図７、図８の例は、図１、図２に示したセブン釘（１ａ）のさらに他の変形例であり、段部３０２を省略した構造であり、製造の容易化、低コスト、又は確実な打込み等を意図する。そして、この例は、杭部２にネジ２０４を設けた構造である。またこの例における他の構造は、前記図１、図２の例に準ずる。以上で説明した釘１は一例であり、他の構造の釘（図示せず）においても、本発明の緩衝部材（後述する）を採用できるものは範疇に含まれる。尚、図示しないが、平面部３０１と段部３０２で構成し、槌叩き部３０３を省略した構造も可能である。この例では、製造が容易で、また低コストによる提供と、又は頭部の強度が向上し、風雨や地震等の災害に対する耐久性の向上を図ることを特徴とする。
【００１２】
本発明の緩衝部材１０の種類としては、図９、図１０に示した一例が好ましい構造である。以下、詳細に説明する。［１］図９（イ）〜（ト）の例は、平面部３０１の下側３０１ａに接着、圧着、溶着等の取付け手段で設けるに適する一例であり、（イ）は断面板状の緩衝部１０ａ、（ロ）は断面台形状の緩衝部１０ａ、（ハ）は断面楕円形状の緩衝部１０ａ、（ニ）は断面倒山形状（突片１０００）の緩衝部１０ａ、（ホ）は断面異形形状（突片１０００）の緩衝部１０ａ、（ヘ）は断面膨出形状（突片１０００）の緩衝部１０ａ、（ト）は断面鋸歯形状（鋸歯１００１）を示した各例である。そして、この各例では、それぞれ特徴がある。例えば、（ニ）、（ホ）、（ヘ）の例は、突片の当り面を有する構造であり、緩衝効果が優れている。また（ト）の例は最も緩衝効果が優れている。さらに（イ）、（ロ）、（ハ）の例は、略平面な当り面を有する構造であり、当初より確実な接触が図れて、安心した釘打ちが可能となる。［２］また図１０（イ）〜（ト）の例は、平面部３０１に筒部１００２を被嵌して設けるに適する一例であり、（イ）は筒部１００２と断面板状の緩衝部１０ａ、（ロ）は筒部１００２と断面台形状の緩衝部１０ａ、（ハ）は筒部１００２と断面楕円形状の緩衝部１０ａ、（ニ）は筒部１００２と断面倒山形状（突片１０００）の緩衝部１０ａ、（ホ）は筒部１００２と断面異形形状（突片１０００）の緩衝部１０ａ、（ヘ）は筒部１００２と断面膨出形状（突片１０００）の緩衝部１０ａ、（ト）は筒部１００２と断面鋸歯形状（鋸歯１００１）の緩衝部１０ａを示した各例である。そして、この各例では、それぞれ前述の図９の例に準じた特徴がある。尚、図示しないが、緩衝部材１０を中空状とすることも可能である。この例では、緩衝効果が向上し、低コスト、軽量化、物体との密着性の向上が図れる等の特徴がある。
【００１３】
尚、図１１（イ）、（ロ）〜図１４（イ）、（ロ）は、前述の図９、図１０に示した緩衝部材１０を、図１、図３、図５、図７に示した釘１に装着した全体の一部欠截の側面図である。例えば、［１］図１１（イ）は、図９（イ）に示した緩衝部材１０を図１に示した釘１に設けた例を、また図１１（ロ）は、図１０（イ）に示した緩衝部材１０を図１に示した釘１に設けた例を、それぞれ示している。［２］同様に図１２（イ）は、図９（イ）に示した緩衝部材１０を図３に示した釘１に設けた例を、また図１２（ロ）は、図１０（イ）に示した緩衝部材１０を図３に示した釘１に設けた例を、それぞれ示している。［３］また図１３（イ）は、図９（イ）に示した緩衝部材１０を図５に示した釘１に設けた例を、また図１３（ロ）は、図１０（イ）に示した緩衝部材１０を図５に示した釘１に設けた例を、それぞれ示している。［４］また図１４（イ）は、図９（イ）に示した緩衝部材１０を図７に示した釘１に設けた例を、また図１４（ロ）は、図１０（イ）に示した緩衝部材１０を図７に示した釘１に設けた例を、それぞれ示している。
【００１４】
そして、緩衝部材１０の基部１０ｂは、頭部３の段差部３０２ａに間隔をもって設けられる。この例では略衝止しており、略所定の位置に取付けられる構造となっている。そして、この構造を採用することで、釘１を打込む際に、緩衝部材１０に損傷を与えないこと、又は固定物（例えば、瓦２０）に確実に接触して緩衝効果、割れ防止等に役立つ有益性があること等の特徴がある。またこの緩衝部材１０の前方１０ｃは、例えば瓦等固定する場合、頭部３の折曲げ部３００の内側に位置するように取付けられる構造となっている。そして、この構造を採用することで、緩衝部材１０の抜け防止と、又は固定物と釘１との緩衝効果の確保が図れること、割れ防止等に役立つ有益性があること等の特徴がある。尚、図１１（イ）〜図１４（イ）の例では、緩衝部材１０の固定位置を釘１の下側３０１ａに設けた係止部（図示せず）とする構造、又は接着、溶着等の手段で固止する構造等が考えられる。そして、この例では、釘１の下側３０１ａの一部に、緩衝部材１０を設けた例であるが、この下側３０１ａの全体に、緩衝部材１０を設ける場合もあり得る（他の例も同じ）。また図１１（ロ）〜図１４（ロ）の筒部１００２の例では、緩衝部材１０を槌叩き部３０３に設けないのが原則である。この部位に緩衝部材１０を設けない理由は、この槌叩き部３０３を打撃するので、当該緩衝部材１０を損傷するからである。尚、一例として、この緩衝部材１０を、釘１の下側３０１ａに設けるに際して、その一部又は全部に、緩衝部材１０を設けた例もあり得る。前述の如く、槌叩き部３０３に緩衝部材１０を設けないことで、例えば、緩衝部材１０の破損回避と、問題発生回避等が図れる実益がある。尚、図示しないが、緩衝部材１０の基部１０ｂを、段差部３０２ａに衝止する構造も可能である。

BACKGROUND OF THE INVENTION
The present invention provides a buffer member at a predetermined portion of the head of the nail so that the fixed object to be nail can be nailed without damaging it, or at this time, securing of the fixed object is ensured. The present invention relates to a nail having a desired buffer characteristic.
[0002]
[Prior art]
Conventionally, as a method intended for buffering at the time of nailing and preventing damage to a fixed object, a configuration in which a packing or a buffering member is provided on the head and / or pile of the nail is known. For example, there are documents such as nails and screws disclosed in JP-A-9-324811, nails disclosed in Japanese Utility Model Application Sho 62-96110, or nails for cement-based inorganic building boards disclosed in Japanese Utility Model Application Sho 63-53429. These documents simply have a structure in which a buffer member is provided in an appropriate part such as the head of a nail or a pile, and the buffering effect is not necessarily sufficient, and the shape of the nail is not specified. Some problems have been pointed out, such as the problem of the nails themselves described below.
[0003]
The problem of the nail itself will be explained. A slightly stepped portion (swelled portion) is formed along the plane length direction at the center of the plane of the nail head. The ball is struck using a hitting means such as a hammer (hereinafter described as a hammer). However, since there is no positioning for hitting the hammer, hitting a position away from the core of the nail pile frequently occurs. Therefore, there is a problem that the load applied to the pile is not transmitted and the bending may occur, and the flat portion of the head also bends downward. Then, when fixing the object on the fixed side (hereinafter referred to as an object) with the flat part of the head, it is visually confirmed whether or not the object and the head are in surface contact, or there is an interval (gap) between the two. It is extremely difficult to visually check whether or not. Therefore, it is possible to damage the object again by hitting it again, or to finish the work with too much clearance to avoid this damage, to generate a defect problem, or to a nail based on regulations (design) There are bad effects such as being unable to beat.
[0004]
As an improvement plan for this type of nail, there is a tile fixing nail disclosed in Japanese Patent Laid-Open No. 8-232404. The content is that the head is formed at the corner of the head and the pile is formed below the head, and the impact load on the head is reliably transmitted to the pile. Intended. This is considered to be intended to prevent the beating head from being bent and to solve the aforementioned problems.
[0005]
However, the invention of this document is a configuration in which the striking head is not on the axis (direction) of the pile, but from a part of the base portion of the flat portion to the substantially central portion of the flat portion, and the impact load applied to the striking head. Has not yet been transmitted to the piles reliably and smoothly.
[0006]
[Problems to be solved by the invention]
In view of the above, the present invention avoids bending, breakage, and the like of a flat portion of a nail head having a cross-sectional shape of a flat shape, a round shape, and a square shape with a hammer. As a means for that purpose, for example, an arbitrary-shaped hammering portion (projecting portion) such as a round shape or a polygonal shape is provided at an optimum position of the flat portion, preferably at a corresponding position on the axis of the pile portion. In order to prevent damage to the object, a buffer member having various forms or characteristics such as elasticity and flexibility is provided on the flat portion of the head using means for bonding, inserting, tightening, and the like. For example, in adhesion, the adhesive is provided at a position where it comes into contact with the counterpart object using an adhesive, molding baking, or the like. Moreover, insertion inserts the cylinder part of a buffer member on a plane part. Or tighten by using means for fitting or the like. In addition, as an object, it aims at the damage prevention of the object, such as earthenware tile, metal tile.

The base portion 10 b of the buffer member 10 is provided at an interval in the stepped portion 302 a of the head 3. In this example, it is substantially stopped and is structured to be attached at a substantially predetermined position. By adopting this structure, when the nail 1 is driven, the buffer member 10 is not damaged, or the fixed member (for example, the roof tile 20) is reliably contacted to provide a buffer effect, crack prevention, or the like. It has features such as useful benefits. Further, the front 10c of the buffer member 10 has a structure that is attached so as to be positioned inside the bent portion 300 of the head 3 when, for example, a roof tile is fixed. And, by adopting this structure, there are features such as prevention of falling off of the buffer member 10 or securing of a buffering effect between the fixed object and the nail 1 and usefulness for preventing cracking. In the examples of FIGS. 11A to 14A, a structure in which the buffer member 10 is fixed to a locking portion (not shown) provided on the lower side 301a of the nail 1 or bonding, welding, or the like. A structure that can be secured by this means is conceivable. In this example, the buffer member 10 is provided on a part of the lower side 301a of the nail 1, but the buffer member 10 may be provided on the entire lower side 301a (other examples may also be provided). the same). In addition, in the example of the cylindrical portion 1002 in FIGS. 11B to 14B, in principle, the buffer member 10 is not provided in the hitting portion 303. The reason why the buffer member 10 is not provided in this portion is that the buffer member 10 is damaged because the hitting portion 303 is hit. As an example, when the buffer member 10 is provided on the lower side 301 a of the nail 1, there may be an example in which the buffer member 10 is provided on a part or all of the buffer member 10. As described above, by not providing the buffer member 10 in the hitting portion 303, there is an advantage that, for example, damage to the buffer member 10 can be avoided and problems can be avoided. Although not shown, a structure in which the base portion 10b of the buffer member 10 is stopped by the stepped portion 302a is also possible.
