Description
【０００１】[0001]
本考案は、刃の交換が可能な替刃式のみに関するものである。 The present invention relates only to a replaceable blade type in which the blade can be replaced.
【０００２】[0002]
のみは、被工作物に穴を空けるためハンマーで叩いたりこじるようにして使用 するため刃体が消耗し破損しやすいものである。しかしながら、刃先を研ぐ作業 は熟練を要すだけでなく手間のかかるものであるため厄介な問題であった。そこ で、消耗した刃を交換するだけでよい替刃式ののみが望まれていた。 The chisel is used by hitting or prying it with a hammer to make a hole in the work piece, and the blade body is easily worn and damaged. However, the work of sharpening the cutting edge is not only a skill-intensive task but also a time-consuming task, which is a troublesome problem. Therefore, only the replaceable blade type, which only needed to replace the worn blade, was desired.
【０００３】 そこで、既に刃体のみを交換可能としたものが開発されている（実公昭５３− １５０３６号）。これは刃体のみを交換するものであるため単価の低減を図るこ とができるが、使用の際に最も力のかかる首部が軸と刃体との連結部分となるた めこじるように使用すると首部がすぐに折れ曲がってしまう危険があった。Therefore, a tool in which only the blade body is replaceable has already been developed (Jitsuko Sho 53-15036). This is because only the blade is replaced, so it is possible to reduce the unit price, but if you use it so that the neck, which exerts the most force during use, becomes the connecting part between the shaft and the blade. There was a danger that the neck would bend immediately.
【０００４】 そのため刃体と軸を一体に形成し、軸の中子を柄体に螺合して交換可能とする ものが開発されている（実公昭５３−２００６９号）。しかしながら、のみの使 用方法が上述のようなものであるため中子の胴部側に無螺子部を設けるとしても 使用中の中子の緩みを避けることはできず、刃体と把持柄との結合部にぐらつき が生じ使用し難く替え刃式のみとしては満足できるものはなかった。Therefore, a blade body and a shaft are integrally formed, and the core of the shaft is screwed into the handle body so that the shaft body can be replaced (Japanese Utility Model Publication No. 53-20069). However, since the only usage method is as described above, slackening of the core during use cannot be avoided even if a non-screw part is provided on the body side of the core, and the blade body and grip handle It was difficult to use because the wobbling occurred at the joint part, and there was nothing satisfactory as a replacement blade type.
【０００５】[0005]
本考案者は、このような問題点を解決すべく軸体を二分割することにより交換 する替刃のコストダウンを図り、かつ刃の交換が簡単でかつ安全確実に固定でき 、しかも使用中に結合部分の中子が緩まずぐらつきがない替え刃式のみを案出し たものである。 The present inventor has attempted to reduce the cost of the replacement blade to be replaced by dividing the shaft body in two in order to solve such a problem, and the blade can be easily and safely fixed in place while being used. Only the replaceable blade type, in which the core of the connecting part does not come loose and wobble, was devised.
【０００６】[0006]
【課題を解決するための手段】 軸体１１の先端には刃体１４を、後端には連結杆１２を形成すると共に、該連 結杆１２の後端近傍の周側面に係合部１３を形成してなる刃体軸体１と、軸体２ １の後端に把持柄４の中子挿入孔４１に挿入固定している中子２２を形成し、軸 体２１には前記連結杆１２を挿入する挿入孔２３を穿設すると共に、挿入孔２３ と直交するねじ孔２４を形成した中間軸体２とからなり、該ねじ孔２４よりねじ ２５を螺入し、中間軸体２の挿入孔２３に挿入した前記連結杆１２の係合部１３ をねじ２５の先端部により押圧し、係合部１３を係合固定しうるようにしてなる ものである。A blade body 14 is formed at the tip of a shaft body 11, a connecting rod 12 is formed at the rear end of the shaft body 11, and an engaging portion 13 is formed on the peripheral side surface near the rear end of the connecting rod 12. And a core body 22 inserted into and fixed to the core insertion hole 41 of the grip handle 4 is formed at the rear end of the shaft body 21 and the shaft body 21 is provided with the connecting rod. The intermediate shaft body 2 is formed with an insertion hole 23 for inserting 12 and has a screw hole 24 orthogonal to the insertion hole 23. A screw 25 is screwed into the screw hole 24 to insert the intermediate shaft body 2. The engaging portion 13 of the connecting rod 12 inserted into the insertion hole 23 is pressed by the tip portion of the screw 25 so that the engaging portion 13 can be engaged and fixed.
【０００７】[0007]
本考案は、以上のような構成であるので次のような作用を有することとなる。 刃体軸体１の連結杆１２を把持柄４に固定している中間軸体２の挿入孔２３に 差し込み、中間軸体２の側部に設けたねじ孔２４よりねじ２５を螺入してねじ２ ５の先端部により連結杆１２の係合部１３を係合押圧するだけで刃体軸体１を把 持柄４に安全確実に固定することができる。そして、刃を交換する場合は、ねじ ２５を緩めて刃体軸体１を中間軸体２の挿入孔２３より抜いた後、新しい刃体軸 体１の連結杆１２を挿入孔２３に挿入固定すればよい。 Since the present invention has the above-mentioned configuration, it has the following effects. Insert the connecting rod 12 of the blade shaft body 1 into the insertion hole 23 of the intermediate shaft body 2 which is fixed to the grip handle 4, and screw in the screw 25 from the screw hole 24 provided on the side portion of the intermediate shaft body 2. The blade shaft body 1 can be securely and reliably fixed to the grip handle 4 only by engaging and pressing the engaging portion 13 of the connecting rod 12 by the tip portion of the screw 25. When replacing the blade, loosen the screw 25 and pull out the blade shaft body 1 from the insertion hole 23 of the intermediate shaft body 2, and then insert and fix the connecting rod 12 of the new blade body shaft body 1 into the insertion hole 23. do it.
【０００８】[0008]
次に図面に基づきながら本考案の実施例を詳述する。 Next, an embodiment of the present invention will be described in detail with reference to the drawings.
【０００９】 １は、刃体軸体であって、軸体１１の先端に形成した刃体１４と、軸体１１の 後端に形成した連結杆１２を形成し、連結杆１２の後端近傍の周側面には係合部 １３を形成している。Reference numeral 1 denotes a blade shaft body, which forms a blade body 14 formed at the tip of the shaft body 11 and a connecting rod 12 formed at the rear end of the shaft body 11, and near the rear end of the connecting rod 12. An engaging portion 13 is formed on the peripheral side surface of the.
【００１０】 係合部１３は、図１のように周側面にリング状に溝を設けて形成してもよいが 、係合部の形状は係合効果があればどのようなものであってもよい。The engaging portion 13 may be formed by providing a ring-shaped groove on the peripheral side surface as shown in FIG. 1. However, the engaging portion 13 may have any shape as long as it has an engaging effect. Good.
【００１１】 例えば、図２のように先端がフラットであるねじ２５の先端面と密着するよう に係合部１３の表面をフラット面１６となるように水平状の直径方向に溝部を形 成することもよい。即ちそのような構成とすると、ねじ孔２４より螺入したねじ ２５の先端面がフラット面１６に密着するのでねじ止め効果が増し刃体軸体１が 回動することなく確実に中間軸体２に固定することができる。For example, as shown in FIG. 2, a groove portion is formed in a horizontal diametrical direction so that the surface of the engaging portion 13 becomes a flat surface 16 so as to be in close contact with the tip surface of the screw 25 having a flat tip. It is also good. That is, with such a configuration, the tip end surface of the screw 25 screwed in from the screw hole 24 comes into close contact with the flat surface 16, so that the screwing effect is increased and the blade shaft body 1 is reliably rotated without rotating. Can be fixed to.
【００１２】 この場合ねじ２５の押圧部が刃面を形成している刃体１４の上面側となるよう に係合部１３を刃体１４の上面側に設けていると、のみは刃体１４の上面方向に 押し上げる様にして使用されるためのみの作用方向と直角方向に刃体軸体１を固 定することとなるので安定性を有することとなる。なお、係合部１３は刃体１４ の上下両面に設け両方からねじ２５にて固定してもよい。In this case, when the engaging portion 13 is provided on the upper surface side of the blade body 14 so that the pressing portion of the screw 25 is on the upper surface side of the blade body 14 forming the blade surface, only the blade body 14 is provided. Since the blade shaft body 1 is fixed in a direction at right angles to the acting direction only for use by pushing it up in the direction of the upper surface, it has stability. The engaging portions 13 may be provided on both upper and lower surfaces of the blade body 14 and fixed with screws 25 from both.
【００１３】 ２は中間軸体であって、軸体２１の後端には把持柄４の中子挿入孔４１に挿入 固定する中子２２を形成し、軸体２１の先端には刃体軸体１に設けた連結杆１２ を挿入する挿入孔２３を穿設し、軸体２１には挿入孔２３と直交するねじ孔２４ を形成している。Reference numeral 2 denotes an intermediate shaft body, and a core 22 is formed at a rear end of the shaft body 21 to be inserted and fixed in a core insertion hole 41 of the grip handle 4, and a blade shaft is provided at a tip end of the shaft body 21. An insertion hole 23 for inserting the connecting rod 12 provided in the body 1 is bored, and a screw hole 24 1 orthogonal to the insertion hole 23 is formed in the shaft body 21.
【００１４】 そして、係合部１３が刃体の上面側となるように、ねじ孔２４よりねじ２５を 螺入しねじ２５の先端により係合部１３を押圧して中間軸体２に刃体軸体１を固 定する。Then, a screw 25 is screwed into the screw hole 24 so that the engaging portion 13 is located on the upper surface side of the blade body, and the engaging portion 13 is pressed by the tip of the screw 25 so that the intermediate shaft body 2 is attached to the blade body. Fix the shaft 1.
【００１５】 なお、図３のように中間軸体２にはねじ孔２４を設けないで嵌合孔２７を形成 して先端に球体２８を持った押圧バネ２９を嵌装していると、中間軸体２の挿入 孔２３に挿入した前記連結杆１２の係合部１３を球体２８の先端部により押圧し て係合固定しうることとなる。As shown in FIG. 3, when the intermediate shaft body 2 is not provided with the screw hole 24 and the fitting hole 27 is formed and the pressing spring 29 having the spherical body 28 at the tip is fitted, The engaging portion 13 of the connecting rod 12 inserted into the insertion hole 23 of the shaft body 2 can be pressed and fixed by the tip of the spherical body 28.
【００１６】 もっとも、図９のように先端に球体２８を持った押圧バネ２９は、連結杆１２ の後端部近傍に設けた嵌合孔１７に嵌装し、中間軸体２には内周面に設けた係合 部１８に球体２８が押圧して係合固定しうるようにしてもよい。Of course, as shown in FIG. 9, the pressing spring 29 having the spherical body 28 at the tip is fitted in the fitting hole 17 provided in the vicinity of the rear end of the connecting rod 12, and the inner peripheral surface of the intermediate shaft body 2 is fitted. The spherical body 28 may be pressed against the engaging portion 18 provided on the surface so as to be engaged and fixed.
【００１７】 また、図５のように連結杆１２をねじ２５にて押圧固定する場合、連結杆１２ の係合部１３にもねじ孔１５を設けておくこともよい。けだし中間軸体２に設け たねじ孔２４に螺入したねじ２５の先端がこのねじ孔１５にまで達しねじ２５に より連結杆１２の係合部１３まで螺着するので刃体軸体１が中間軸体２に確実に 固定されることとなるからである。Further, when the connecting rod 12 is pressed and fixed by the screw 25 as shown in FIG. 5, the engaging portion 13 of the connecting rod 12 may be provided with a screw hole 15. The tip of the screw 25 screwed into the screw hole 24 provided in the baring intermediate shaft body 2 reaches the screw hole 15 and is screwed by the screw 25 to the engaging portion 13 of the connecting rod 12. This is because it is securely fixed to the intermediate shaft body 2.
【００１８】 また、図４のように連結杆１２を断面多角形とすると共に中間軸体２の挿入孔 ２３にも連結杆１２と対応する断面多角形を設けていると連結杆１２を挿入孔２ ３に確実に差込み固定できる。しかも係合部１３の周面にはフラット面を有する こととなりねじ孔２４より螺入したねじ２５の先端面がフラット面に密着するの で刃体軸体１がより以上に回動することなく確実に中間軸体２に固定することが できる。Further, as shown in FIG. 4, if the connecting rod 12 has a polygonal cross section, and the inserting hole 23 of the intermediate shaft 2 is also provided with a polygonal cross section corresponding to the connecting rod 12, the connecting rod 12 can be inserted into the inserting hole. It can be securely inserted and fixed to 23. Moreover, since the peripheral surface of the engaging portion 13 has a flat surface, the tip end surface of the screw 25 screwed into the screw hole 24 comes into close contact with the flat surface, so that the blade shaft body 1 does not rotate further. It can be reliably fixed to the intermediate shaft body 2.
【００１９】 また、図６のように連結杆１２をねじ状とし中間軸体２の挿入孔２３に螺入す るようにする場合には、更に軸体１１の側部に設けたねじ孔２４よりねじ２５を 螺入しねじ２５の先端により連結杆１２に設けた係合部１３を押圧して中間軸体 ２に刃体軸体１を固定すると便利である。けだし、単に把持柄に刃体を螺入した ものではないので使用中の緩みが生じにくく刃体軸体１が中間軸体２に完全に固 定され使用中における刃体軸体１のぐらつきが生じないからである。Further, as shown in FIG. 6, when the connecting rod 12 is formed in a screw shape so as to be screwed into the insertion hole 23 of the intermediate shaft body 2, a screw hole 24 provided on a side portion of the shaft body 11 is further provided. It is convenient to screw in the screw 25 and press the engaging portion 13 provided on the connecting rod 12 with the tip of the screw 25 to fix the blade shaft body 1 to the intermediate shaft body 2. Since the blade body is not simply screwed into the grip handle, it does not easily loosen during use, and the blade body shaft body 1 is completely fixed to the intermediate shaft body 2 so that the blade body shaft body 1 wobbles during use. Because it does not occur.
【００２０】 また、図７のように先端に刃体１１Ａを、後端に頭部１２Ａを太鼓腹状とした テーパー状軸部１３Ａを形成してなる刃体軸体１Ａと、後端に把持柄４Ａに差込 み固定する中子２１Ａを、先端に刃体軸体１Ａのテーパー状軸部１３Ａを嵌合す るテーパー状凹部２２Ａを穿設すると共に、ピン挿通孔２３Ａをテーパー状凹部 ２２Ａの後端部と直交するように貫通して設けた中間軸体２Ａとからなり、刃体 軸体１Ａのテーパー状軸部１３Ａを中間軸体２Ａのテーパー状凹部２２Ａに強入 固定しうるようにしていると、刃を交換する場合にピン挿入孔２３Ａにピン５Ａ を挿入するだけで刃体軸体１Ａの後端部をピン５Ａの側面により押し出すように なるため刃体軸体１Ａを中間軸体２Ａより容易に取り外すことができるので便利 である。Further, as shown in FIG. 7, a blade 11A is formed at the front end and a tapered shaft 13A having a head 12A at the rear end is formed into a drum shape. A core 21A that is inserted into and fixed to the handle 4A is formed, and a tapered concave portion 22A into which the tapered shaft portion 13A of the blade shaft body 1A is fitted is formed at the tip, and a pin insertion hole 23A is formed into a tapered concave portion 22A. The intermediate shaft body 2A is provided so as to penetrate through so as to be orthogonal to the rear end portion of the blade body. When the blade is replaced, the rear end of the blade shaft body 1A can be pushed out by the side surface of the pin 5A simply by inserting the pin 5A into the pin insertion hole 23A when replacing the blade body shaft 1A in the middle. It is convenient because it can be easily removed from the shaft 2A. is there.
【００２１】 なお、図８のように刃体軸体を取り外すときのみ別体のピンを使用するのでは なく、中間軸体２Ａにテーパー状軸部１３Ａの頭部１２Ａを受ける凹部３１Ａを 側面に持ったピン３Ａをテーパー状凹部２２Ａの後端部と直交するように貫通し たピン挿通孔２３Ａに挿通していると、刃体軸体１Ａをテーパー状凹部２２Ａよ り抜く場合には、テーパー状凹部２２Ａの後端部と直交するように貫通している ピン３Ａの中間軸体２Ａより突出している先端部分をハンマーなどで叩くと刃体 １１Ａの後端頭部１２Ａを押し出すようにしながら中間軸体２Ａより外れ同時に 刃体軸体１Ａはテーパー状凹部２２Ａより外れることとなり刃の交換作業を非常 に能率よく行なうことができる。Note that, instead of using a separate pin only when removing the blade shaft body as shown in FIG. 8, a recess 31A for receiving the head portion 12A of the tapered shaft portion 13A is formed on the side surface of the intermediate shaft body 2A. If the pin 3A is inserted into the pin insertion hole 23A that penetrates so as to be orthogonal to the rear end of the tapered recess 22A, when the blade shaft body 1A is pulled out from the tapered recess 22A, a taper is formed. When the tip portion of the pin 3A penetrating perpendicularly to the rear end portion of the concave portion 22A protruding from the intermediate shaft body 2A is hit with a hammer or the like, the rear end head portion 12A of the blade body 11A is pushed out and the middle The blade shaft body 1A comes off the tapered recessed portion 22A at the same time as it comes off from the shaft body 2A, so that the blade replacement work can be performed very efficiently.
【００２２】[0022]
本考案は、上述のような構成よりしてなるものであるので次のような効果を有 することとなる。 Since the present invention is configured as described above, it has the following effects.
【００２３】 本考案では、刃体軸体１の連結杆１２を把持柄４に取り付けた中間軸体２の挿 入孔２３に差込み、ねじ２５を軸体２１のねじ孔２４に螺入するだけで刃体軸体 １を中間軸体２に確実に固定できる。それ故、刃の交換を容易に行なうことがで きるから刃先が磨耗などしても刃先を研ぐ必要がなく使用上の作業性をアップす ることができる。In the present invention, the connecting rod 12 of the blade shaft body 1 is inserted into the insertion hole 23 of the intermediate shaft body 2 attached to the grip handle 4, and the screw 25 is simply screwed into the screw hole 24 of the shaft body 21. The blade shaft body 1 can be securely fixed to the intermediate shaft body 2. Therefore, since the blade can be easily replaced, it is not necessary to sharpen the blade even if the blade is worn, and the workability in use can be improved.
【００２４】 刃体軸体１の連結杆１２にねじ２５の先端が嵌まるように係合部１３を設け、 その部分に螺入したねじ２５により先端部を押圧するようにしているので確実に 固定でき使用中の刃体軸体１のぐらつきをなくすことができる。An engaging portion 13 is provided on the connecting rod 12 of the blade shaft body 1 so that the tip of the screw 25 fits, and the tip portion is pressed by the screw 25 screwed into that portion, so that it is reliable. It can be fixed and wobble of the blade shaft 1 in use can be eliminated.
【００２５】 使用の際最も力点がかかる刃体の上面側（刃面側）に係合部１３を設け、ねじ ２５や押圧バネ２９を螺入又は押圧する様にしているのでのみの作用方向に対し 直角方向に刃体軸体１を固定することとなり刃体がぐらつかず安定した使用がで きる。The engaging portion 13 is provided on the upper surface side (blade surface side) of the blade body to which the most force is applied during use, and the screw 25 and the pressing spring 29 are screwed or pressed, so that the action direction is only On the other hand, since the blade body 1 is fixed in the right angle direction, the blade body does not wobble and can be used stably.
【００２６】 連結杆１２は、合金工具鋼等を素材としていると、柔軟性を有するので係合部 １３の成形が容易であり、又この部分に負担がかかるような使用をしても柔軟性 を有するので折れ難くなる。When the connecting rod 12 is made of alloy tool steel or the like, the connecting rod 12 has flexibility, so that the engaging portion 13 can be easily formed, and the connecting rod 12 is flexible even if it is used with a load. Since it has, it is difficult to break.
【００２７】 係合部１３を連結杆１２の後端近傍に設けているため安定感があり使用中の連 結杆１２のぶれを防ぐことができるのでのみ本体のぐらつきなく使用しやすいも のとなる。Since the engaging portion 13 is provided in the vicinity of the rear end of the connecting rod 12, there is a sense of stability and it is possible to prevent the connecting rod 12 from shaking during use, so that the main body is easy to use without wobbling. Become.
【００２８】 本考案では刃体軸体１は、把持柄４に直接取付けるのではなく中間軸体２を介 して取付けるようにしているので刃の交換の際は、中間軸体２部分の交換が必要 でないため安価な替え刃の提供が可能となる。In the present invention, the blade shaft body 1 is mounted not through the grip shaft 4 directly but through the intermediate shaft body 2. Therefore, when replacing the blade, the intermediate shaft body 2 is replaced. Since it is not necessary, it is possible to provide an inexpensive replacement blade.
【００２９】 また、のみを使用する場合に最も力のかかる部分は、刃体と軸体との連接部分 であるが、本考案では軸体を下方の刃体軸体１と上方の中間軸体２とに二分割し 、刃体１４と下方の軸体１１とは一体に連接して刃体軸体１を形成し、把持柄４ に直接固定する上方の中間軸体２とは下方の軸体１１の後端に設けた連結杆１２ により連結するようにしているため刃体と軸体との連結部分が脆弱となることは ない。従って使用中に連結部分が折れるような心配はないので安心して作業する ことができる。Further, the portion to which the most force is applied when only using is the connecting portion between the blade body and the shaft body, but in the present invention, the shaft body is the lower blade body shaft body 1 and the upper intermediate shaft body. 2, the blade body 14 and the lower shaft body 11 are integrally connected to each other to form the blade body shaft body 1, and the upper intermediate shaft body 2 which is directly fixed to the grip handle 4 is a lower shaft body. Since the connecting rod 12 is provided at the rear end of the body 11, the connecting portion between the blade body and the shaft body does not become fragile. Therefore, there is no fear that the connecting part will break during use, so you can work with peace of mind.
【００３０】 図５のように刃体軸体１Ａのテーパー状軸部１３Ａを中間軸体２Ａの先端に穿 設したテーパー状凹部２２Ａに強入するだけで連結することができるような構成 としていると、刃の交換を容易かつ迅速に行なうことができる。のみはハンマー などで叩打して使用するため上記構成のものであっても刃体軸体１Ａがテーパー 状凹部２２Ａより抜け出るおそれはないばかりか使用すればするほど強く連結す ることとなる。As shown in FIG. 5, the tapered shaft portion 13A of the blade shaft body 1A can be connected only by forcibly inserting it into the tapered recessed portion 22A formed at the tip of the intermediate shaft body 2A. The blade can be replaced easily and quickly. Since only the blade body is tapped with a hammer or the like for use, the blade shaft body 1A is not likely to come out of the tapered concave portion 22A even with the above structure, and the stronger the connection, the stronger the connection.
【００３１】 また、刃体軸体１Ａをテーパー状凹部２２Ａより抜く場合には、テーパー状凹 部２２Ａの後端部と直交するように中間軸体２Ａを貫通しているピン挿通孔２３ Ａにピン３Ａを差し込みピン３Ａの頭部をハンマーなどで叩くとピン３Ａは刃体 １１Ａの後端頭部１２Ａを押し出すように作用するので簡単に刃体軸体１Ａはテ ーパー状凹部２２Ａより外れることとなり刃の交換作業が非常に能率よく行なう ことができる。When the blade shaft body 1A is pulled out from the tapered recessed portion 22A, the pin insertion hole 23A penetrating the intermediate shafted body 2A is orthogonal to the rear end of the tapered recessed portion 22A. When the pin 3A is inserted and the head of the pin 3A is hit with a hammer or the like, the pin 3A acts so as to push out the rear end head 12A of the blade 11A, so that the blade shaft body 1A should be easily disengaged from the tapered recess 22A. The adjacent blades can be replaced very efficiently.
