Description

本発明は替刃である刃体が刀身本体に着脱可能に取り付けて使用される剃刀等の刃物に関する。この種の刃物は顔剃りや毛髪のカット用の剃刀や医療用、病理用のナイフなどに使用される。The present invention relates to a blade such as a razor in which a blade body which is a replacement blade is detachably attached to a blade body. This type of blade is used for razors for face shaving and hair cutting, knives for medical use and pathology.

金属製の背金を備える刃体が刀身本体に装着された刃物は、製造の際の寸法誤差や経年変化などが原因で替刃(刃体)と刀身本体との間に隙間の生じることがある。また刃体は前端の挿脱口から刀身本体に着脱可能に挿脱されるが、替刃の挿脱に起因する磨耗などにより刀身本体(中空部)に保持される刃体に緩みが生じることがある。剃刀を例にとると、刀身本体の中空部に弾性体である板ばねを配設する一方、中空部に装着された替刃がこれと当接する板ばねの付勢力で押圧され、替刃が安定して保持される構造のものが開発されている。この場合、中空部における板ばねの不要な移動を阻止するため、板ばねの基端が刀身本体に固定されている。固定手段としては、例えば、刀身本体内の部材間に板ばねの基端を挟着して固定する構造がある(実公昭45年第11778号公報参照)。また、板ばねの基端の小突起を刀身本体の厚み方向に貫通する小孔に内側から引っ掛けて固定する構造が知られている(図示せず)。しかし小孔の厚みは1mm程度であり、この薄い厚み部分に小突起を引っ掛けているにすぎない。一方、替刃と刀身本体との装脱着の際には替刃を刀身本体の長手方向に移動させるが、このとき替刃が板ばねに摺接して板ばねに長手方向の力が働くため、従来の固定手段では経年的な使用等によって板ばねが離脱するおそれもある。
実公昭45年第11778号には、前記のように、刀身本体内の部材間に板ばねの基端を挟着し、板ばねを刀身本体に固定する剃刀が開示されている。
A blade with a metal back metal blade attached to the blade body may have a gap between the blade (blade) and the blade body due to dimensional errors during manufacturing or changes over time. is there. The blade body is removably inserted into and removed from the blade body through the insertion / removal port at the front end, but the blade body held in the blade body (hollow part) may be loosened due to wear caused by the insertion / removal of the replacement blade. is there. Taking a razor as an example, a leaf spring, which is an elastic body, is disposed in the hollow portion of the blade body, while the replaceable blade mounted on the hollow portion is pressed by the urging force of the leaf spring in contact with the blade, and the replaceable blade is A structure that is stably held has been developed. In this case, the base end of the leaf spring is fixed to the blade body in order to prevent unnecessary movement of the leaf spring in the hollow portion. As a fixing means, for example, there is a structure in which a base end of a leaf spring is sandwiched and fixed between members in the blade body (see Japanese Utility Model Publication No. 11778). Further, there is known a structure (not shown) in which a small protrusion at the base end of a leaf spring is hooked and fixed from the inside to a small hole penetrating in the thickness direction of the blade body. However, the thickness of the small hole is about 1 mm, and only a small protrusion is hooked on this thin thickness portion. On the other hand, when attaching and detaching the replacement blade and the blade body, the replacement blade is moved in the longitudinal direction of the blade body.At this time, the replacement blade slides on the leaf spring and a longitudinal force acts on the leaf spring. In the conventional fixing means, the leaf spring may be detached due to aging.
As described above, Japanese Utility Model Publication No. 11778 discloses a razor in which a base end of a leaf spring is sandwiched between members in a blade body and the leaf spring is fixed to the blade body.

本発明は、刀身本体に配設される板ばねを安定して保持するとともに、経年的な使用に対しても有効な刃物を提供することを課題とする。さらに刀身本体に板ばねを簡易かつ確実に取り付けることができる刃物を提供することを課題とする。An object of the present invention is to stably hold a leaf spring disposed in a blade body and to provide an effective blade for aged use. It is another object of the present invention to provide a blade that can easily and reliably attach a leaf spring to a blade body.

上記課題を解決するため本発明にかかる刃物は次のような手段をとる。すなわち、刃体が刀身本体に出し入れ可能であり、刀身本体の刃体保持部に装着された刃体が板ばねの付勢力により押圧されるように構成された刃物において、刀身本体は刀身本体下縁に開口する係合凹部を有し、板ばねは基端に係合凹部へ向け屈曲して延びる係合突片を設け、開口より挿入して係合凹部に係合される係合突片が被覆体により被覆される一方、係合凹部は溝部における側面部の延設方向に直交する方向であり、かつ側面部の厚み方向の全域に亘り形成され、刃体の前後方向の移動により刃体に摺接する板ばねに前後方向の力が加わるとき、全体がほぼ弓形に湾曲する板ばねにおける湾曲状態が変形するとともに、当該湾曲状態が変化する板ばねの基端に設けられた係合突片は、前面が対向する係合凹部の内側面、後面が対向する係合凹部の内側面にそれぞれほぼ全面的に面接触するように前後方向へ移動可能に係合凹部と係合される。また一対の係合凹部が対向する側面部に直列的に形成され、いずれか一方の係合凹部に係合突片が係合される。そして刃物は剃刀とすることができる。In order to solve the above problems, the blade according to the present invention takes the following means. That is, the blade body can be inserted into and removed from the blade body, and the blade body mounted on the blade body holding portion of the blade body is pressed by the urging force of the leaf spring. An engagement recess that has an engagement recess that opens at the edge, and that the leaf spring is provided with an engagement projection that extends and bends toward the engagement recess at the base end. Is covered by the covering body, while the engaging recess is formed in the direction orthogonal to the extending direction of the side surface portion in the groove portion and is formed over the entire thickness direction of the side surface portion, and the blade is moved by moving the blade body in the front-rear direction. When a longitudinal force is applied to the leaf spring that is in sliding contact with the body, the curved state of the leaf spring that is generally curved in an arcuate shape is deformed, and the engagement protrusion provided at the base end of the leaf spring that changes the curved state. One side is the inner surface of the engaging recess facing the front and the rear is facing Each inside surface of Rukakarigo recess is engaged with the almost exclusively movably engaging recesses in the front-rear direction so as to surface contact. Moreover, a pair of engagement recessed part is formed in series in the side part which opposes, and an engagement protrusion is engaged with any one engagement recessed part. And the blade can be a razor.

本発明にかかる刃物によれば、例えば、狭い溝部内側から側面部に貫通する小孔へ板ばねの小突起を引っ掛けていた従来の剃刀と比べ、係合突片を含む板ばねの刀身本体への取り付けが簡易かつ確実であり、刀身本体に安定して保持される。従ってまた刀身本体における刃体の摺動により板ばねが所定位置から離脱することもなく、長期の使用にも耐えうる。According to the blade according to the present invention, for example, compared to a conventional razor in which a small protrusion of a leaf spring is hooked into a small hole penetrating from the inside of a narrow groove to a side surface, to a blade body of a leaf spring including an engagement protrusion. Is easy and reliable, and is stably held on the blade body. Accordingly, the leaf spring does not move away from the predetermined position due to sliding of the blade body in the blade body, and can withstand long-term use.

本発明を実施するための最良の形態を剃刀について説明する。剃刀1は刀身本体2とハンドル3とを備える。ここで剃刀のハンドル3とは剃刀1を手で握持される細長い柄の部分をいい、また剃刀の刀身本体2とは切断用具としハンドル3に連結される刃物の基本部分(但し刃体を除く)であり、刀身本体2に刃体5を装着して刀身が構成される。すなわち刀身本体2は単に刃体5を保持する刃体保持部Cだけでなく、基部Dなどこれと一体的に構成されたすべての部分を含む。刀身本体2は通常、金属製であるがこれに限定されない。The best mode for carrying out the present invention will be described for a razor. The razor 1 includes a blade body 2 and a handle 3. Here, the razor handle 3 is an elongated handle part that is held by the hand of the razor 1, and the razor blade body 2 is a cutting tool that is a basic part of the blade connected to the handle 3. The blade body is configured by attaching the blade body 5 to the blade body 2. That is, the blade body 2 includes not only the blade body holding portion C that holds the blade body 5 but also all the parts such as the base portion D that are integrally formed therewith. The blade body 2 is usually made of metal, but is not limited thereto.

刀身本体2は刃体を出し入れする前端の挿脱口7と、刃体の挿脱口7から刀身本体の長手方向に延びる刃体保持部Cを備える。刃体保持部Cは一対の側面部9a、9aを設け、対向する側面部の下縁8a、8a間に間隙がある(側面部の「下縁」とは図3における下側をさす)。すなわち刃体保持部Cは対向する側面部の下縁側が開口する中空構造である。刀身本体2は刃体保持部Cと連設された基部Dを備え、基部Dにはその長手方向に溝部Eが形成されている。溝部Eは並行する一対の側面部9b、9bと底部4を有し、刃体保持部Cと同じく、側面部9b、9bの下縁8b、8b間が開口する中空構造であり、中空の刃体保持部Cと中空の溝部Eが連設されている。The blade body 2 includes a front end insertion / removal port 7 through which the blade body is inserted and removed, and a blade body holder C extending from the blade body insertion / removal port 7 in the longitudinal direction of the blade body. The blade body holding portion C is provided with a pair of side surface portions 9a, 9a, and there is a gap between the lower edges 8a, 8a of the opposing side surface portions (the “lower edge” of the side surface portions refers to the lower side in FIG. 3). That is, the blade body holding part C has a hollow structure in which the lower edge side of the opposing side part is opened. The blade body 2 includes a base D connected to the blade holder C, and a groove E is formed in the base D in the longitudinal direction. The groove portion E has a pair of side surface portions 9b, 9b and a bottom portion 4 which are parallel to each other. Like the blade body holding portion C, the groove portion E has a hollow structure in which the lower edges 8b, 8b open between the side surface portions 9b, 9b. The body holding part C and the hollow groove part E are connected.

中空の刃体保持部Cには弾性体である1枚の板ばねAが刀身本体2の長手方向に配設されている。湾曲する板ばねAは基端が刀身本体2に保持あるいは固定される一方、中央部が刃体保持部Cの一方の側面部9aの内側面に適宜に弾接している(図6参照)。前端の挿脱口7から刃体保持部Cに挿入される刃体5は、板ばねAの前端10側から基端側へと板ばねAの側面に沿って摺動し、所定位置に配置される。中空の刃体保持部C内の刃体5は、腹部に当接する板ばねAの付勢力により一方の側面部9aの方向に押圧され、刃体保持部Cに安定して配置される(図6、7、8参照)。また刃体保持部Cに配置された刃体5は逆に前端10側へと移動させ挿脱口7から取り出される。このように刀身本体2に替刃である刃体5が着脱可能に装着され、装着された刃体5は刃先5aが刃体保持部の側面部の下縁8aから突出する。In the hollow blade body holding portion C, a single leaf spring A, which is an elastic body, is disposed in the longitudinal direction of the blade body 2. The bent spring A is held or fixed at the base body 2 by the base end, and the central portion is appropriately elastically in contact with the inner side surface of one side surface portion 9a of the blade body holding portion C (see FIG. 6). The blade body 5 inserted into the blade body holding portion C from the insertion / removal port 7 at the front end slides along the side surface of the leaf spring A from the front end 10 side to the base end side of the leaf spring A and is disposed at a predetermined position. The The blade body 5 in the hollow blade body holding portion C is pressed in the direction of the one side surface portion 9a by the urging force of the leaf spring A contacting the abdomen, and is stably disposed on the blade body holding portion C (see FIG. 6, 7, 8). Further, the blade body 5 arranged in the blade body holding portion C is moved to the front end 10 side and taken out from the insertion / removal port 7. Thus, the blade body 5 which is a replacement blade is detachably mounted on the blade body 2, and the blade edge 5 a of the mounted blade body 5 protrudes from the lower edge 8 a of the side surface portion of the blade body holding portion.

全体としてほぼ弓形に湾曲する板ばねAは基端において屈曲して延びる係合突片6を有する。係合突片6は板ばねAと一体に形成され、また、例えば、板ばねÅ1のように係合突片の幅は板ばねの幅と同じである(ここで係合突片の「幅」、板ばねの「幅」とは図9における高さ(上下)方向の長さをいう)。しかしその幅は常に同じである必要はなく、異なってもよい。係合突片は1個だけでなく複数個、設けてもよく、また板ばねの基端におけるその設定位置も任意である。図11乃至13に示される板ばねA2は基端の上縁側と下縁側に一対(2個)の係合突片6、6を有する。また図14乃至16に示される板ばねA3は基端における幅方向のほぼ中間部に1個の係合突片6を有する。いずれの場合も係合突片の幅は板ばねの基端の幅の3分の1以上、望ましくは2分の1以上とする。複数個の係合突片6を設けたときは各係合突片の幅を加えたものが同じ条件を満たすようにする。これにより係合突片6と係合凹部Bとの係合が安定する。As a whole, the leaf spring A curved in a substantially arcuate shape has an engagement protrusion 6 that bends and extends at the proximal end. The engagement protrusion 6 is formed integrally with the leaf spring A. For example, the width of the engagement protrusion is the same as the width of the leaf spring as in the case of the leaf spring rod 1 (here, the “width of the engagement protrusion”). The “width” of the leaf spring means the length in the height (up and down) direction in FIG. 9). However, the widths need not always be the same and may be different. A plurality of engaging protrusions may be provided instead of only one, and the setting position at the base end of the leaf spring is also arbitrary. The plate spring A2 shown in FIGS. 11 to 13 has a pair (two pieces) of engaging protrusions 6 and 6 on the upper edge side and the lower edge side of the base end. Further, the leaf spring A3 shown in FIGS. 14 to 16 has one engagement protrusion 6 at a substantially intermediate portion in the width direction at the base end. In any case, the width of the engaging protrusion is at least one third of the width of the base end of the leaf spring, preferably at least one half. When a plurality of engagement protrusions 6 are provided, the width of each engagement protrusion is added so that the same condition is satisfied. Thereby, engagement with the engagement protrusion 6 and the engagement recessed part B is stabilized.

図17、18に示される板ばねA4は基端においてL字状に屈曲して延びる係合突片6を有し、図19,20に示される板ばねA5は基端において鉤状に屈曲して延びる係合片6を備える。図21,22に示される板ばねA6は直線状に延びる基端部13の下端から下方へ屈曲する係合突片6を有する。係合突片6の長さ、屈曲角度、方向などは係合凹部Bとの配置関係などにより適宜に決定される。また弾性体である板ばねAの全体形状は弓形に限定されず、台形状、S字状、波状などでもよい。またその材質も金属が望ましいが、アモルファス材やプラスチックなどでもよい。The leaf spring A4 shown in FIGS. 17 and 18 has an engagement protrusion 6 that extends and bends in an L shape at the base end, and the leaf spring A5 shown in FIGS. 19 and 20 is bent in a hook shape at the base end. The engaging piece 6 is extended. The leaf spring A6 shown in FIGS. 21 and 22 has an engaging protrusion 6 that bends downward from the lower end of the base end portion 13 that extends linearly. The length, bending angle, direction, and the like of the engagement protrusion 6 are appropriately determined depending on the arrangement relationship with the engagement recess B and the like. The overall shape of the leaf spring A, which is an elastic body, is not limited to an arcuate shape, but may be a trapezoidal shape, an S shape, a wave shape, or the like. The material is preferably a metal, but may be an amorphous material or plastic.

刀身本体2には高さ方向(図3における上下方向)の係合凹部Bが形成され、係合凹部は刀身本体下縁に開口している。刃体保持部、基部を備える刀身本体2において係合凹部Bが基部Dの溝部Eに形成されている。すなわち基部Dの長手方向に設けられた溝部Eは対向する側面部9b、9bと底部4を備え、側面部9bまたは底部4に係合凹部Bが形成される。側面部9bにおける係合凹部Bの場合、側面部9bを厚み方向に切り欠き、対向する側面部9b、9bに一対の係合凹部Bが直列的に形成されている(図6、23参照)。係合凹部Bは側面部9bの延設方向に直交する方向であり、側面部9bの厚み方向の全域に亘り形成されているが、その形成方向や角度は任意である。また図24に示される側面部9bの係合凹部Bは溝部Eの内側から幅方向に一部を切り欠いて形成したものである。なお係合凹部Bは一方の側面部のみに形成してもよい(図示せず)。The blade body 2 is formed with an engagement recess B in the height direction (vertical direction in FIG. 3), and the engagement recess opens at the lower edge of the blade body. An engagement recess B is formed in the groove E of the base D in the blade body 2 including the blade body holding part and the base. That is, the groove portion E provided in the longitudinal direction of the base portion D includes the side portions 9 b and 9 b and the bottom portion 4 that face each other, and the engaging recess B is formed in the side portion 9 b or the bottom portion 4. In the case of the engaging recess B in the side surface portion 9b, the side surface portion 9b is notched in the thickness direction, and a pair of engaging recess portions B are formed in series on the opposing side surface portions 9b and 9b (see FIGS. 6 and 23). . The engaging recess B is a direction orthogonal to the extending direction of the side surface portion 9b and is formed over the entire area in the thickness direction of the side surface portion 9b, but the formation direction and angle are arbitrary. 24 is formed by cutting out a part in the width direction from the inside of the groove E. The engaging recess B may be formed only on one side surface (not shown).

係合凹部Bには板ばねA1乃至A3の基端に設けられた屈曲する係合突片6が係合される(図23参照)。係合突片6は一方の側面部9bにおける係合凹部Bに向け屈曲して延びている。係合凹部Bに係合される係合突片6は先端が側面部9bの外側面9cから突出せず、ほぼ面一状態かあるいはこれに近い状態とするのが望ましい(図23参照)。しかし係合突片6の先端が外側面に達しないものでもよく、また逆に外側面から突出してもよい(後述の板ばねA4、5と係合凹部Bとの係合の説明参照)。側面部9bの延設方向に直交方向であり、かつ側面部9bの厚み方向の全域に亘り係合凹部Bが形成されている場合(図23参照)、係合突片6と係合凹部Bとの係合が容易であり安定する。係合凹部Bの前後方向の間隔は、通常、薄い板状の係合突片6を係合するに足る長さかあるいはそれよりやや長めとすればよく、1mmから2mm程度でも十分である(板ばねA1乃至A5の場合)。また刀身本体が金属製の場合、複数の刀身本体を並列するとともに溝部の両側面部9bを厚み方向に切削して切り欠くなど、機械的方法により刀身本体に係合凹部を形成するのは容易である。なお対向する側面部に一対の係合凹部Bが形成されている場合、板ばねA(1枚の場合)の係合突片Aはいずれか一方の係合凹部Bに係合される。The engaging recess B is engaged with a bending engaging protrusion 6 provided at the base end of the leaf springs A1 to A3 (see FIG. 23). The engagement protrusion 6 bends and extends toward the engagement recess B in one side surface portion 9b. It is desirable that the engaging protrusion 6 engaged with the engaging recess B does not protrude from the outer surface 9c of the side surface portion 9b, and is in a substantially flush state or a state close thereto (see FIG. 23). However, the tip of the engagement protrusion 6 may not reach the outer surface, and conversely, may protrude from the outer surface (see the description of engagement between the leaf springs A4, 5 and the engagement recess B described later). When the engagement recess B is formed in the direction perpendicular to the extending direction of the side surface portion 9b and over the entire thickness direction of the side surface portion 9b (see FIG. 23), the engagement protrusion 6 and the engagement recess B Is easy and stable. The interval in the front-rear direction of the engagement recess B may be a length sufficient to engage the thin plate-like engagement protrusion 6 or slightly longer than that, and about 1 mm to 2 mm is sufficient (plate Springs A1 to A5). In addition, when the blade body is made of metal, it is easy to form the engagement recesses in the blade body by a mechanical method, such as arranging a plurality of blade bodies in parallel and cutting both side surfaces 9b of the groove portion in the thickness direction. is there. In addition, when a pair of engagement recessed part B is formed in the side part which opposes, the engagement protrusion A of the leaf | plate spring A (in the case of 1 sheet) is engaged with any one engagement recessed part B. FIG.

係合凹部Bは側面部の下縁8bから溝部Eの底部4まで達し、垂直状に形成されている。係合凹部Bの断面は矩形状でありその大きさも同じである。しかし断面形状や大きさが部分的に異なったものでもよく、また係合凹部は傾斜状に形成してもよい(図示せず)。板ばねAおよび合突片6の幅は係合凹部Bの深さ(側面部の下縁8bから溝部の底部4までの長さ)とほぼ同じか若干小さいのが望ましい(図28参照)が、大きくてもよい(図示せず)。図29、30に示される板ばねA2、A3は係合突片6の幅が係合凹部Bの深さよりかなり小さい。溝部の底部4はほぼ平面状である(図4参照)が、湾曲面などでもよい(図示せず)。また刃体保持部Cの底部14のように、両内側縁14aより中央部が低くなった逆V字形の底部としてもよい。The engaging recess B extends from the lower edge 8b of the side surface to the bottom 4 of the groove E, and is formed vertically. The cross section of the engaging recess B is rectangular and has the same size. However, the cross-sectional shape and size may be partially different, and the engaging recess may be formed in an inclined shape (not shown). The widths of the leaf spring A and the mating protrusion 6 are preferably substantially the same as or slightly smaller than the depth of the engaging recess B (the length from the lower edge 8b of the side surface portion to the bottom portion 4 of the groove portion) (see FIG. 28). It may be large (not shown). In the plate springs A2 and A3 shown in FIGS. 29 and 30, the width of the engagement protrusion 6 is considerably smaller than the depth of the engagement recess B. The bottom 4 of the groove is substantially planar (see FIG. 4), but may be a curved surface (not shown). Moreover, it is good also as an inverted V-shaped bottom part where the center part became lower than both inner edge 14a like the bottom part 14 of the blade holding | maintenance part C.

また係合凹部Bには板ばねA4の鉤状に屈曲する係合突片6が係合され(図25参照)、係合凹部Bには板ばねA5のL字状に屈曲する係合突片6が係合される(図26)。これらは係合突片6の先端部が側面部の外側面9cから突出している例である。この場合、係合突片6は側面部の外側面9cへ屈曲して延びるとともに、外側面9cに当接する先端部が、板ばねA4ではさらに刀身本体2の前端側に屈曲し、板ばねA5ではさらに刀身本体2の基端側に屈曲している。いずれも係合突片6が係合凹部Bから外れないように確実に係合される。Further, the engagement protrusion B is engaged with an engagement protrusion 6 that is bent in the shape of a flange of the leaf spring A4 (see FIG. 25), and the engagement protrusion B is engaged with an engagement protrusion that is bent in the L shape of the leaf spring A5. The piece 6 is engaged (FIG. 26). These are examples in which the front end portion of the engaging protrusion 6 protrudes from the outer side surface 9c of the side surface portion. In this case, the engaging protrusion 6 bends and extends to the outer side surface 9c of the side surface portion, and the front end portion that contacts the outer side surface 9c is further bent toward the front end side of the blade body 2 by the leaf spring A4, and the leaf spring A5. Then, it is further bent toward the base end side of the blade body 2. In any case, the engagement protrusions 6 are securely engaged so as not to be disengaged from the engagement recesses B.

次に溝部の底部4における係合凹部Bの場合、底部4に凹陥した係合凹部Bは溝部の一方の側面部9bに並行する横長のスリット状に形成されている(図27、31参照)。一方の側面部9bに近接する位置にある係合凹部Bには板ばねA6の係合突片6、つまり板ばねA6の延出する基端部13から下方へ屈曲して延びる係合突片6が係合される。以上、いずれの場合も高さ方向に形成された係合凹部Bは、側面部の下縁8bあるいは底部4など、刀身本体2下縁に開口している。Next, in the case of the engaging recess B in the bottom 4 of the groove, the engaging recess B recessed in the bottom 4 is formed in a horizontally long slit shape parallel to one side surface portion 9b of the groove (see FIGS. 27 and 31). . In the engaging recess B at a position close to one side surface portion 9b, the engaging protrusion 6 of the leaf spring A6, that is, the engaging protrusion extending from the base end portion 13 where the leaf spring A6 extends is bent downward. 6 is engaged. As described above, in any case, the engaging recess B formed in the height direction opens at the lower edge of the blade body 2 such as the lower edge 8b or the bottom 4 of the side surface.

板ばねAは刀身本体下縁の開口から刀身本体2に挿着される。すなわち刃体保持部Cおよび基部Dの下縁(8a、8aおよび8b、8b)間の長手方向の開口の下方位置に湾曲する板ばねAを配し(図3参照)、その湾曲状態を部分的に変形する(直線状にする)など適宜に調整をしながら板ばねAを開口より中空の刃体保持部および溝部に挿入する。それと同時に係合凹部Bに係合突片6を差し込むと係合突片6が係合凹部Bに係合される。両側面部9b、9bに一対の係合凹部Bがある場合は、前記のようにいずれか一方の係合凹部Bに係合突片6を係合すればよい。刃体保持部Cに配置された板ばねAの前端10(自由端)は刃体保持部Cの内側面に当接される。いずれの場合も刀身本体2下縁(側面部の下縁8bや底部4など)に開口する係合凹部Bに対し、刀身本体2の下縁側から開口を通して係合突片6が係入され、係合突片6と係合凹部Bとの係合が容易となる。特に底部4の係合凹部Bに係合突片6を係合する場合、板ばね6の基端部13を中空の溝部Eに挿入すると、下方へ屈曲して延びる係合突片6がほぼ自動的に係合凹部Bに係合し、その係合はさらに容易である。The leaf spring A is inserted into the blade body 2 from the opening at the lower edge of the blade body. That is, a leaf spring A that is curved is disposed at a position below the longitudinal opening between the lower edges (8a, 8a and 8b, 8b) of the blade body holding part C and the base part D (see FIG. 3), and the curved state is partially The leaf spring A is inserted into the hollow blade holder holding part and the groove part through the opening while making appropriate adjustments such as deformation (straightening). At the same time, when the engagement protrusion 6 is inserted into the engagement recess B, the engagement protrusion 6 is engaged with the engagement recess B. When there is a pair of engaging recesses B on the side surface portions 9b, 9b, the engaging protrusions 6 may be engaged with either one of the engaging recesses B as described above. The front end 10 (free end) of the leaf spring A disposed in the blade body holding portion C is in contact with the inner surface of the blade body holding portion C. In any case, the engaging protrusion 6 is engaged through the opening from the lower edge side of the blade body 2 with respect to the engaging recess B that opens at the lower edge of the blade body 2 (the lower edge 8b, the bottom portion 4 and the like of the side surface portion), Engagement between the engagement protrusion 6 and the engagement recess B is facilitated. In particular, when the engagement protrusion 6 is engaged with the engagement recess B of the bottom portion 4, when the base end portion 13 of the leaf spring 6 is inserted into the hollow groove E, the engagement protrusion 6 that is bent downward and extends substantially It automatically engages with the engagement recess B, and the engagement is even easier.

刃体5は刀身本体2の長手方向(前後方向)に移動して刃体保持部Cに挿脱されるが、刃体5の前後方向への移動に伴い刃体5の腹面と摺接する板ばねAに対して前後方向の力が働く。一方、係合凹部Bに係合した係合突片6は係合凹部Bと当接して板ばねの前後方向の移動を阻止する。係合突片6が側面部9bの厚み方向に配置された場合(板ばねA1乃至A5、図23乃至26参照)、係合突片6が係合凹部Bと面接触する例である。すなわち係合突片6は前面がこれに対向する係合凹部Bの内側面と、また後面がこれに対向する係合凹部Bの内側面とほぼ全面的に面接触する。少なくとも刃体5の前後方向の移動にともない、板ばねAに前後方向の力が加わるとき両者はほぼ全面的に面接触する(図8参照)。係合突片6の幅と板ばねの幅が同じである場合(板ばねA1、A4,A5)、係合突片6が前後方向の力をほぼ全体で均一に受け、板ばねAは安定して保持される。また係合突片6と係合凹部Bとの接触面積が大きく、板ばねAの移動を有効に阻止する。The blade body 5 moves in the longitudinal direction (front-rear direction) of the blade body 2 and is inserted into and removed from the blade body holding portion C, but a plate that is in sliding contact with the abdominal surface of the blade body 5 as the blade body 5 moves in the front-rear direction. A force in the front-rear direction acts on the spring A. On the other hand, the engagement protrusion 6 engaged with the engagement recess B abuts on the engagement recess B to prevent the leaf spring from moving in the front-rear direction. In this example, the engagement protrusion 6 is in surface contact with the engagement recess B when the engagement protrusion 6 is disposed in the thickness direction of the side surface portion 9b (see plate springs A1 to A5 and FIGS. 23 to 26). That is, the front surface of the engaging protrusion 6 is substantially in contact with the inner surface of the engaging recess B facing the front surface and the inner surface of the engaging recess B facing the front surface. At least along with the movement of the blade body 5 in the front-rear direction, when a force in the front-rear direction is applied to the leaf spring A, the two are almost in surface contact (see FIG. 8). When the width of the engagement protrusion 6 is the same as the width of the leaf spring (leaf springs A1, A4, A5), the engagement protrusion 6 receives the force in the front-rear direction almost uniformly and the leaf spring A is stable. Held. Further, the contact area between the engagement protrusion 6 and the engagement recess B is large, and the movement of the leaf spring A is effectively prevented.

次に係合突片6がスリット状の係合凹部Bの前後方向に配置された場合(板ばねA6、図27参照)、係合突片6が係合凹部Bと線接触をする例である。係合突片6は上下方向に延びる線状の前部がこれに対向する係合凹部Bの内側面と、また上下方向に延びる線状の後部がこれに対向する係合凹部Bの内側面とほぼ全体的に線接触する。この場合も線接触により前後方向の大きな力に対応することができ、板ばねAが安定して保持される。なお以上いずれも板ばねAが1枚の場合について説明したが、板ばねAは複数でもよい。例えば、刃体保持部Cに一対の弓形に湾曲する板ばねA1を両者の凸曲面がたがいに当接するように対向して配置し、両板ばねA1の自由端である前端間から挿入された刃体を両板ばねA間に押圧挟持するとともに、それぞれの係合突片6を対向する係合凹部Bに係合する(図示せず)。Next, when the engagement protrusion 6 is disposed in the front-rear direction of the slit-shaped engagement recess B (see the leaf spring A6, FIG. 27), the engagement protrusion 6 is in line contact with the engagement recess B. is there. The engagement protrusion 6 has an inner surface of the engagement recess B facing the linear front portion extending in the vertical direction and an inner surface of the engagement recess B facing the linear rear portion extending in the vertical direction. Line contact almost entirely. Also in this case, a large force in the front-rear direction can be dealt with by line contact, and the leaf spring A is stably held. In addition, although the above demonstrated the case where the number of leaf | plate springs A was one, the number of leaf | plate springs A may be sufficient. For example, a pair of arcuate leaf springs A1 are arranged on the blade holder C so as to face each other so that their convex curved surfaces come into contact with each other, and are inserted from between the front ends that are free ends of both leaf springs A1. The blade body is pressed and clamped between the two leaf springs A, and the respective engagement protrusions 6 are engaged with the opposing engagement recesses B (not shown).

ハンドル3は前端の取付口20とこれに連続する中空部21を有する。板ばねAの装着された刀身本体2は基部Dをハンドル3と固定して一体化される。固定方法としては、取付口20から刀身本体の基部Dをハンドルの中空部21に嵌入し、刀身本体2をハンドル3に嵌着する。あるいはハンドルの中空部21に挿入された刀身本体の基部Dを接着剤や超音波ウエルダー加工によりハンドル3に固着し、刀身本体2をハンドル3に固定することができるが、その固定方法、手段は問わない。The handle 3 has a mounting opening 20 at the front end and a hollow portion 21 continuous therewith. The blade body 2 to which the leaf spring A is attached is integrated with the base D fixed to the handle 3. As a fixing method, the base D of the blade main body is inserted into the hollow portion 21 of the handle from the attachment port 20, and the blade main body 2 is inserted into the handle 3. Alternatively, the base D of the blade main body inserted into the hollow portion 21 of the handle can be fixed to the handle 3 by an adhesive or ultrasonic welder processing, and the blade main body 2 can be fixed to the handle 3. It doesn't matter.

係合凹部Bの開口における係合突片6は被覆体により被覆されている。図1、2の場合、合成樹脂製などのハンドル3と一体化された刀身本体はハンドルの中空部21の内周面22が係合凹部Bの開口を塞ぎ、ハンドル3が係合凹部Bの開口における係合突片6を被覆している。係合突片6は被覆体3に当接しているのが望ましいが、両者間に間隙があってもよい。例えば、板ばねA3の係合突片6の場合、被覆体と係合突片6との間に隙間が生じる(図30参照)。被覆体と係合突片6との間に接着剤や充填剤など配置されこれらが係合凹部Bの開口を塞いでいる場合は、接着剤や充填剤が被覆体となる。またベルト、テープのような帯状物で溝部Eの外周を巻回して係合凹部Bの開口を塞ぎ、あるいはプレート状物で係合凹部の開口を被蓋する(図示せず)。この場合は帯状物やプレート状物が係合突片6を被覆する被覆体である。係合凹部の開口から係合突片の一部が外側に突出していてもよく、このときも係合突片は帯状物やプレート状物など適宜な被覆体により被覆される(図示せず)。いずれもの場合も被覆体3は係合突片6が係合凹部Bの開口から離脱するのを防止する。The engagement protrusion 6 at the opening of the engagement recess B is covered with a cover. In the case of FIGS. 1 and 2, in the blade body integrated with the handle 3 made of synthetic resin or the like, the inner peripheral surface 22 of the hollow portion 21 of the handle closes the opening of the engagement recess B, and the handle 3 The engaging protrusion 6 in the opening is covered. The engaging protrusion 6 is preferably in contact with the covering 3, but there may be a gap between them. For example, in the case of the engagement protrusion 6 of the leaf spring A3, a gap is generated between the cover and the engagement protrusion 6 (see FIG. 30). When an adhesive, a filler, or the like is disposed between the covering body and the engaging protrusion 6 and closes the opening of the engaging recess B, the adhesive or the filler becomes the covering body. Further, the outer periphery of the groove E is wound with a belt-like material such as a belt or tape to close the opening of the engaging recess B, or the opening of the engaging recess is covered with a plate-like material (not shown). In this case, the belt-shaped object or the plate-shaped object is a covering that covers the engaging protrusion 6. A part of the engaging protrusion may protrude outward from the opening of the engaging recess, and at this time, the engaging protrusion is covered with an appropriate covering such as a strip or plate (not shown). . In any case, the covering 3 prevents the engagement protrusion 6 from being detached from the opening of the engagement recess B.

係合凹部Bの開口を塞ぐ被覆体がハンドル3である場合、刀身本体2 をハンドル3に嵌着するなど両者を連結して一体化するのみで係合凹部B内の係合突片6が被覆され、効率的な被覆が可能となる。透明素材で形成されたハンドル3が場合、被覆体のハンドル3により係合凹部Bや係合突片6が外側から目視されないから好都合である。尤も透明素材で形成されたハンドル3の場合、係合凹部Bの狭い開口が目視されても必ずしも不体裁ではない。しかし帯状物やプレート状物などの被覆体で係合突片を被覆すれば、外観上の不体裁は確実になくなる。本発明は、刀身本体2をハンドル3と固定して一体化される固定式剃刀(図1参照)だけでなく、折り畳み式の剃刀、つまり、刀身本体の基部がハンドルの先端部の近傍に枢着され、ハンドルの収納部に刀身本体に折り畳み可能に収納される剃刀(図示せず)についても適用される。When the cover that closes the opening of the engagement recess B is the handle 3, the engagement protrusion 6 in the engagement recess B can be formed simply by connecting the blade body 2 to the handle 3 and integrating them. Coated and efficient coating is possible. In the case of the handle 3 formed of a transparent material, it is advantageous because the engagement recess B and the engagement protrusion 6 are not visually recognized from the outside by the handle 3 of the cover. However, in the case of the handle 3 formed of a transparent material, even if the narrow opening of the engaging recess B is visually observed, it is not necessarily unnatural. However, if the engagement protrusions are covered with a covering such as a strip or plate, the appearance is surely eliminated. The present invention is not limited to a fixed razor (see FIG. 1) in which the blade body 2 is fixed and integrated with the handle 3, but also a folding razor, that is, the base of the blade body is pivoted near the tip of the handle. The present invention is also applied to a razor (not shown) that is worn and stored in a handle storage part so as to be foldable in the blade body.

以上みたように、係合凹部Bに係合された係合突片6は、係合凹部Bとの当接あるいは当接可能性による板ばねの前後方向への移動の阻止機能と、被覆体との当接あるいは当接可能性による板ばねの高さ方向への移動の阻止機能を備え、これにより板ばねAが刀身本体2に安定して保持される。なお最適な実施例の1つとして剃刀について説明をしたが、本発明はカッターナイフ、医療用、病理用ナイフ(例えば、トリミングナイフ)などの刃物にも実施可能である。As described above, the engagement protrusion 6 engaged with the engagement recess B is in contact with the engagement recess B or the function of preventing movement of the leaf spring in the front-rear direction by the contact possibility, and the covering body. The leaf spring A is stably held on the blade body 2 by the function of preventing the leaf spring from moving in the height direction. Although a razor has been described as one of the most suitable embodiments, the present invention can be applied to blades such as a cutter knife, a medical knife, and a pathological knife (for example, a trimming knife).
