Description

本考案は、木材の縦割りに使用する金矢と称されている楔金具に関するものである。 The present invention relates to a wedge fitting called a gold arrow used for vertically dividing wood.

木材の縦割りにおいて、一般に鉞が知られているが、前記の鉞は柄を備えており（特許文献１、実開昭５８−１８５１７９号公報）、単体で木材の木口からの縦割りを実現している。然し長尺木材の縦割りにおいては、木材の木口からの縦割りを行うことができないので、鉞の頭部金具のみを備えた形態の金矢と称されている金属製の楔形金具を使用し、木材の周面から割りを実施しているものである。 In the vertical splitting of wood, cocoons are generally known, but the above-mentioned cocoons have a handle (Patent Document 1, Japanese Utility Model Publication No. 58-185179), and realize vertical splitting from the mouth of wood by itself. is doing. However, in the longitudinal division of long timber, since it is not possible to perform the vertical division from the mouth of the timber, use a metal wedge-shaped bracket called a gold arrow with a form with only the head bracket of the heel, Splitting is performed from the circumferential surface of the timber.

即ち長尺木材の縦割りに際しては、鉞を振り回して木材の周面へ食い込ませる場合に、必ずしも特定の部位に正確に食い込ませることができず、ずれてしまう虞が大きい。また鉞の頭部を更にハンマー等によって強打して鉞頭部の刃先を更に深く木材に食い込ませる場合には、柄が邪魔になってしまう。 That is, when a long timber is vertically divided, when the cocoon is swung around and sunk into the circumferential surface of the timber, the slab cannot be squeezed into a specific part accurately, and there is a high possibility of shifting. In addition, when the head of the heel is further struck by a hammer or the like, and the blade edge of the heel head is further deeply cut into the wood, the handle becomes an obstacle.

このために長尺木材の縦割りに際しては、前記したとおり金矢と称されている金属製の楔形金具が使用されるもので、所定の箇所に配置した楔形金具に打撃を加えて木材に喰い込ませ、更にハンマーによって楔形金具を強打し、相応の割れが生じたなら、その割れ目に木製楔を打ち込んで割れ目を確保し、次の箇所で楔形金具を打ち込み、更に割れ目を形成するようにして長尺木材の縦割りを実施しているものである。 For this reason, when cutting long wood vertically, a metal wedge-shaped metal fitting called a gold arrow is used as described above, and the wedge-shaped metal fitting placed at a predetermined location is struck to bite into the wood. In addition, if a wedge-shaped bracket is struck with a hammer and a corresponding crack occurs, a wooden wedge is driven into the crack to secure a crack, and the wedge-shaped bracket is driven into the next place to further form a crack. This is a vertical division of the scale wood.

ところで、楔形金具（金矢）を使用する場合に、前記金具を所定の位置に置き、強打する前に木材に食い込ませて直立状態としなければならない。この金具直立作業は、金具を手で保持して、ハンマーによって打撃を加えるものであるが、金具保持者に怪我をさせないように慎重に行なわなければならなく、弱打を数回繰り返すことによって行なうことになり、作業能率低下の原因となっている。 By the way, when using wedge-shaped metal fittings (gold arrows), the metal fittings must be placed in a predetermined position and bitten into wood before being struck, so that they must be in an upright state. This bracket upright work is to hold the bracket by hand and hit it with a hammer, but it must be done carefully so as not to injure the bracket holder, and it is done by repeating weak hits several times. As a result, work efficiency is reduced.

そこで本考案は、金具直立作業を効果的に行うことのできる新規な楔金具を提案したものである。 Therefore, the present invention proposes a novel wedge bracket that can effectively perform the bracket upright operation.

本考案に係る楔金具は、頂部に打撃受け部を備え、底辺に刃先部を備えると共に、適宜箇所に柄着脱部を設けた楔本体と、前記柄着脱部と対応する装着構造を備えた柄体とで構成してなることを特徴とするものである。 A wedge fitting according to the present invention includes a wedge body provided with an impact receiving portion at the top, a blade edge portion at the bottom, and a handle attaching / detaching portion at an appropriate location, and a handle provided with a mounting structure corresponding to the handle attaching / detaching portion. It is characterized by comprising a body.

而して楔本体に柄体を装着した状態で、切断対象の木材の所定箇所に楔本体が位置するように柄体を握持し、楔本体をハンマーで強打して木材に喰い込ませ、楔本体を直立状態とし、柄体をはずした後、更に楔本体をハンマーで強打して木材の縦割りを実現する。 Thus, with the handle body mounted on the wedge body, grip the handle body so that the wedge body is located at a predetermined position of the wood to be cut, smash the wedge body with a hammer and bite into the wood, After the wedge body is in an upright state and the handle is removed, the wedge body is further smashed with a hammer to realize the vertical division of the wood.

本考案の楔金具は上記の構成を備えたもので、初期の楔本体の直立作業時にのみ柄体を楔本体に装着して前記の直立作業を容易に且つ効率的に行なえるようにし、木材の縦割り作業時には邪魔になる柄体を外すので、木材縦割りの作業効率を向上させるものである。 The wedge bracket of the present invention has the above-described configuration. The handle is attached to the wedge body only during the initial upright operation of the wedge body so that the upright work can be performed easily and efficiently. Since the pattern body that gets in the way is removed during vertical cutting work, the work efficiency of vertical wood cutting is improved.

次に本考案の実施形態について説明する。実施形態に示した楔金具は、楔本体１と、柄体２とで構成される。 Next, an embodiment of the present invention will be described. The wedge fitting shown in the embodiment includes a wedge body 1 and a handle 2.

楔本体１は、基本的に従前の金矢と称される金具と同様で、頂部に打撃受け部１１を備え、底辺に刃先部１２を備え、更に柄着脱部１３を設けたもので、前記柄着脱部１３は、楔本体１の端面上部（鉞の柄装着箇所と一致）に螺穴で形成されてなる。 The wedge body 1 is basically similar to a metal fitting called a conventional gold arrow, and is provided with an impact receiving portion 11 at the top, a blade edge portion 12 at the bottom, and a handle attaching / detaching portion 13. The detachable portion 13 is formed by a screw hole in the upper end surface of the wedge body 1 (corresponding to the heel handle mounting location).

柄体２は、適宜な把手部２１を備え、先部に前記柄着脱部（螺穴）１３と対応する装着部（螺棒）２２を備えたものである。 The handle body 2 is provided with an appropriate handle portion 21 and a mounting portion (screw rod) 22 corresponding to the handle attaching / detaching portion (screw hole) 13 at the tip portion.

而して楔本体１の柄着脱部（螺穴）１３に、柄体２の装着部（螺棒）２２を螺合装着し、切断対象の木材Ａの所定箇所に楔本体１が位置するように柄体２を握持し、楔本体１をハンマーＢで強打して木材に喰い込ませる（図２イ）。 Thus, the mounting portion (screw rod) 22 of the handle 2 is screwed into the handle attaching / detaching portion (screw hole) 13 of the wedge main body 1 so that the wedge main body 1 is positioned at a predetermined position of the wood A to be cut. Grip the handle 2 and smash the wedge body 1 with a hammer B to bite it into the wood (FIG. 2a).

楔本体１が木材Ａに食い込んで直立状態とした後、柄体２を外し、単体となった楔本体１をハンマーＢで強打して木材の縦割りを行なうものである（図２ロ）。 After the wedge main body 1 bites into the wood A to be in an upright state, the handle 2 is removed, and the single wedge main body 1 is struck with a hammer B to vertically divide the wood (FIG. 2B).

また本考案は前記の実施形態に限定されるものではなく、前記の螺穴を差込穴とし、螺棒を差込棒としても良いし、また図３に例示するとおり、楔本体１ａの両側面適宜箇所に柄装着部１３ａとして溝部を設け、柄体２ａの先部に前記柄装着部（溝部）１３ａと対応する二股の棒状の装着部２２ａを設け、装着部（二股棒）２２ａの柄装着部（溝部）１３ａへの抜き差しで柄体２ａの着脱を行うようにしても良い。 The present invention is not limited to the above-described embodiment, and the screw hole may be an insertion hole, and the screw rod may be an insertion rod. Also, as illustrated in FIG. A groove portion is provided as a handle mounting portion 13a on an appropriate surface, and a bifurcated rod-shaped mounting portion 22a corresponding to the handle mounting portion (groove portion) 13a is provided at the tip of the handle body 2a. The handle of the mounting portion (bifurcated rod) 22a The pattern body 2a may be attached and detached by inserting / removing it into / from the mounting portion (groove portion) 13a.
