Abstract
Description
本発明は木材用の木ねじに関するものである。 The present invention relates to a wood screw for wood.
図１と図２に示すように従来の木ねじは、その本体（１）にねじ部（１１）が設けてあり、その前端は一つの錐形部となっていて、本体（１）の最尖端（１０）と、ねじ部（１１）の最前端との間にある一定の距離がある。即ちねじ部（１１）の前端起点は前端の錐状部の中にあり、最尖端（１０）ではない。 As shown in FIG. 1 and FIG. 2, the conventional wood screw has a threaded portion (11) in its main body (1), and its front end is a single conical portion, which is the sharpest end of the main body (1). There is a certain distance between (10) and the foremost end of the threaded portion (11). That is, the front end starting point of the threaded portion (11) is in the conical portion at the front end, not the tip end (10).
そのため、従来の木ねじを各種の工作物にねじ込む時は、ねじ部（１１）が直ちにねじ切りの作用を発生せずに、ある深さまで前進してからねじ（１１）の前端起点（１１０）が工作物の中に入って始めて、回転ねじ孔切り作用を発生する。この様に従来の木ねじを工作物にねじ込む時は直ちにねじ孔切りの作用を発生しない。その理由はねじ部（１１）の前端起点（１１０）が錐状部の中に位置して、決して最尖端（１０）に達していないからである。そのために従来の木ねじは迅速なねじ込みをすることができない。 Therefore, when the conventional wood screw is screwed into various workpieces, the threaded portion (11) does not immediately generate a threading action, but advances to a certain depth and the front end starting point (110) of the screw (11) is moved to the workpiece. Only when it enters the object, a rotating thread drilling action occurs. In this way, when a conventional wood screw is screwed into a workpiece, there is no immediate effect of thread drilling. The reason is that the front end starting point (110) of the threaded portion (11) is located in the conical portion and never reaches the most distal end (10). Therefore, conventional wood screws cannot be screwed in quickly.
本発明は上述した従来の木ねじの欠点を改善するために成されたもので、その目的とするところは迅速なねじ込み不可能の点を改善することにある。 The present invention has been made to remedy the above-mentioned drawbacks of conventional wood screws, and its object is to improve the point of being unable to be screwed in quickly.
本発明の木ねじはそのねじ部の前端起点を少なくともその本体の最尖端まで伸ばすか、或は最尖端を超過させて、ねじの前端起点と前端部との間に一偏心のねじ刃を形成させる。 The wood screw of the present invention extends the front end starting point of the threaded portion to at least the most apical end of the main body or exceeds the most apex end to form an eccentric screw blade between the front end starting point and the front end of the screw. .
すなわち、本願の木ねじに係る第１発明は、その本体に一つのねじ部を設け、前記ねじ部の最前端が本体の最尖端を超過することを特徴とするものである。
本願の木ねじに係る第２発明は、前記第１発明において、前記ねじ部の最前端と前記本体の最尖端との間に一段の切り刃を持ち、前記切り刃は更に前記本体の最尖端の前方に伸びて、前記切り刃が前記ねじの回転中心線と偏倚することを特徴とするものである。
本願の木ねじに係る第３発明は、その本体に一つのねじ部を設け、前記ねじ部は前記本体の最尖端よりも少し前方に伸びる最前端を持つことを特徴とするものである。
本願の木ねじに係る第４発明は、前記第３発明において、前記ねじ部の最前起点は前記本体の最尖端との間に一段の偏心の切り刃を持ち、前記切り刃はその最前端が前記本体の最尖端の前方に伸び出て、前記切り刃が前記本体の回転中心線から偏倚することを特徴とするものである。
That is, the first invention relating to the wood screw of the present application is characterized in that one screw portion is provided in the main body, and the foremost end of the screw portion exceeds the most pointed end of the main body.
A second invention related to the wood screw of the present application is the first invention, wherein the first screw has a one-stage cutting blade between the foremost end of the threaded portion and the most apical end of the main body, and the cutting blade is further provided at the apex of the main body. The cutting blade extends forward and the cutting blade is offset from the rotation center line of the screw.
The third invention relating to the wood screw of the present application is characterized in that one screw portion is provided in the main body, and the screw portion has a foremost end extending slightly forward from the most pointed end of the main body.
According to a fourth aspect of the present invention related to the wood screw of the present invention, in the third aspect of the present invention, the foremost starting point of the threaded portion has a one-stage eccentric cutting edge between the most acute end of the main body, and the cutting edge has the foremost end described above. The cutting blade extends forward of the tip of the main body, and the cutting blade is deviated from the rotation center line of the main body.
本発明の木ねじのねじ部の前端起点は最尖端まで、或いはそれを超過しているか、工作物にねじ込まれる時はただちにねじ切りの作用を発生するのでねじ付け作業が迅速に進展する。 Since the front end starting point of the threaded portion of the wood screw of the present invention reaches or exceeds the most extreme end, or when it is screwed into the workpiece, a threading action is generated immediately, so that the screwing operation proceeds rapidly.
本発明に係る木ねじは次の特有の効果を奏する。
＜１＞木ねじは、ねじ部の最前端の切り刃が工作物にねじ込まれる瞬間から孔開けの作業を開始するので、ねじ付け作業を迅速に行えて、時間を節約することができる。
＜２＞木ねじの構造が簡単で、実用性に優れている。
＜３＞産業上の利用性が極めて高く、経済価値も高い。
The wood screw according to the present invention has the following specific effects.
<1> Since the wood screw starts the drilling operation from the moment the cutting edge at the foremost end of the threaded portion is screwed into the workpiece, the screwing operation can be performed quickly and time can be saved.
<2> The structure of the wood screw is simple and excellent in practicality.
<3> Industrial applicability is extremely high and economic value is also high.
以下、添付図面を参照して本発明の好適な実施の形態を詳細に説明する。
図３，４，５に本発明に係る木ねじの第一実施例を示す。
この木ねじは木ねじ（１）の本体にその最尖端（１０）を超過するねじ部（１１）を設けると共に、ねじ部（１１）の最前端はねじ本体の最尖端（１０）との間に一段の切り刃（１２）を持たせる。この切り刃（１２）はねじ本体（１）の回転中心線から少し偏倚している。そして、ねじ（１）を工作物にねじ込む瞬間、最初に切り刃（１２）が直接工作物と接触することで、ねじ込み孔開け作業を迅速に行うことができて、木ねじを早く工作物にねじ込むことができる。
DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
3, 4 and 5 show a first embodiment of a wood screw according to the present invention.
This wood screw is provided with a threaded portion (11) exceeding the sharpest end (10) in the body of the wood screw (1), and the foremost end of the threaded portion (11) is one step between the sharpest end (10) of the screw body. A cutting blade (12) is provided. This cutting blade (12) is slightly deviated from the rotation center line of the screw body (1). Then, at the moment of screwing the screw (1) into the workpiece, the cutting blade (12) is first brought into direct contact with the workpiece, so that the screwing hole can be drilled quickly and the wood screw is screwed into the workpiece quickly. be able to.
更に図６，７，８に本発明の第二実施例に係る木ねじを示す。本例は木ねじ（１）の本体にねじ部（１１）の最前端が本体の最尖端（１０）を超えて少し前まで伸びていて、最尖端（１０）との間に一段の切り刃（１２）を形成し、この切り刃（１２）はねじ（１）の回転中心線から偏倚している。それでこの木ねじを工作物の中にねじ込ませるその瞬間に、この切り刃（１２）がまっさきに直接工作物と接触するので、ねじ込み孔開け作業を迅速に行うことができて、木ねじを早く工作物にねじ込むことができる。 Further, FIGS. 6, 7 and 8 show wood screws according to a second embodiment of the present invention. In this example, the foremost end of the threaded portion (11) extends to the front of the wood screw (1) slightly beyond the apex (10) of the main body, and a single cutting edge ( 12), and this cutting edge (12) is offset from the rotational center line of the screw (1). Therefore, at the moment when the wood screw is screwed into the work piece, the cutting blade (12) is in direct contact with the work piece, so that the screw hole can be drilled quickly, and the wood screw can be quickly turned into the work piece. Can be screwed in.
