本発明は、合成樹脂を用いた鍵及びその製造方法に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a key using synthetic resin and a method for manufacturing the same.
従来の鍵は殆どは真鍮、鉄、ステンレス等の金属材料か
らなり、鍵穴に挿入する鍵部と該鍵に一体として連結す
る頭部とからなっていた。Most conventional keys are made of metal materials such as brass, iron, stainless steel, etc., and consist of a key part that is inserted into a keyhole and a head part that is integrally connected to the key.
しかしながら、全体が金属でできているので重量が重い
という問題点があった。However, since it is entirely made of metal, it has the problem of being heavy.
そこで、該鍵を合成樹脂によって製造することが考えら
れるが、合成樹脂で鍵を作ると、強度が不足し、鍵が使
用中あるいは保管中に折れる心配があるという問題点が
あった。Therefore, it has been considered to manufacture the key from synthetic resin, but when the key is made from synthetic resin, there is a problem that the strength is insufficient and there is a risk that the key may break during use or storage.
また、鍵自体は小型であるので紛失し易く、−全体が金
属によって構成されているので、ファション性にも乏し
いという問題点もあった。Furthermore, since the key itself is small, it is easy to lose it, and since it is entirely made of metal, it is not very fashionable.
本発明はこのような事情に鑑みてなされたもので、強度
を有し、しかも軽量で取扱い易く、色彩の選択を自由に
行える鍵及びその製造方法を提供することを目的とする
。The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a key that is strong, lightweight, easy to handle, and allows the user to freely select a color, and a method for manufacturing the same.
上記目的に沿う本発明に係る鍵は、鍵穴に挿入する鍵部
の断面凹凸に合わせて屈曲させた金属芯材を非鍵山部に
配置し、全体が硬質の合成樹脂材から構成されている。A key according to the present invention that achieves the above object is made entirely of a hard synthetic resin material, with a metal core bent in accordance with the cross-sectional unevenness of the key to be inserted into the keyhole placed in the non-key thread part.
ここで、鍵はカードの内側に一体成形されて、しかも鍵
頭部の先端で上記カードに接続され、その接続部が回動
自在となっているもの、及びその接続部に布、グラスフ
ァイバー等の屈曲性補強部材が配置されているものであ
っても本発明は適用される。Here, the key is integrally molded inside the card, and is connected to the card at the tip of the key head, and the connection part is rotatable, and the connection part is made of cloth, glass fiber, etc. The present invention is applicable even if a flexible reinforcing member is disposed.
そして、上記目的に沿う本発明に係る鍵の製造方法は、
先端部にホルダー片が設けられて、鍵部に埋設される部

を作り、しかる後該金属芯材を長手方向に保持し、該金
属芯材が中央に位置させて外側に合成樹脂成形を行い、
上記ホルダー片鍵部先端から切り離すようにして構成さ
れている。And, the method for manufacturing a key according to the present invention in accordance with the above object is as follows:
A holder piece is provided at the tip, and the part to be embedded in the key part is made of a metal core material that is bent and molded to match the cross-sectional unevenness of the key part, and then the metal core material is held in the longitudinal direction and the metal core material is The metal core material is placed in the center and synthetic resin is molded on the outside.
The holder piece is configured to be separated from the tip of the key part.
本発明に係る鍵においては、鍵部の断面凹凸に合わせて
屈曲させた金属芯材が非鍵山部に配置されているので、
鍵部の断面係数の向上を図ることができる。In the key according to the present invention, since the metal core material bent to match the cross-sectional unevenness of the key part is arranged in the non-key thread part,
It is possible to improve the section modulus of the key part.
また、材料の主要部が合成樹脂からなっているので、色
彩の選択が自由とあり、更には成形加工も容易となり、
例えば、カード等の内部に鍵の形を成形することも可能
となる。In addition, since the main part of the material is made of synthetic resin, you can freely choose the color, and it is also easier to mold.
For example, it is also possible to mold the shape of a key inside a card or the like.
鍵の製造方法においては、鍵部に配置される金属芯材に

属からなっている。As shown in FIGS. 1 and 2, the key lO according to an embodiment of the present invention is made entirely of hard synthetic resin, and has a metal core 11 inside as shown by dotted lines in FIG. is located. Examples of the hard synthetic resins include polyetherimide resin, polycarbonate resin, polyethersulfone resin, polybutylene terephthalate resin, polyphenylene sulfide resin, polysanfon resin, polyethylene terephthalate resin, polyacetal resin, polyamide resin, polypropylene resin, and methacrylic resin. , modified PPE resin, ABS resin, AS resin, etc.
The metal core material is made of a metal that is relatively sticky and does not easily corrode, such as a stainless steel plate, a brass plate, or a plated iron plate.
鍵穴に挿入される鍵部１２は予め所定の鍵山１３．１４
が形成される部分と、中央の鍵山が形成されない非鍵山
部１５とを有し、該非鍵山部１５に連接される頭部（ホ
ルダ一部）１６には、該鍵１０をキーホルダー等に連結
する為の開口部１７が形成されている。The key part 12 inserted into the keyhole has predetermined key threads 13 and 14.
The key 10 is connected to a key holder, etc. to a head (a part of the holder) 16 connected to the non-key ridge portion 15. An opening 17 is formed for this purpose.
上記鍵部１５には、長手方向に２本（１本あるいは３本

る。In the key part 15, two (sometimes one or more than three) grooves 18 and 19 are formed in the longitudinal direction to form an uneven cross section, but the metal core material 11 inside is also formed. It is molded to match this unevenness and is placed exactly in the center of the key part 12 in the thickness direction, thereby reinforcing the key part.
ここで、金属芯材１１は頭部１６まで広がって全体を補
強しているが、外側の合成樹脂との馴染みを良くする為
表面に適当な凹凸を形成することが好ましく、該凹凸は
プレス加工による内被、プレス加工による物理的凹凸、
サンドブラスト加工等によって行うことが可能である。Here, the metal core material 11 extends to the head 16 and reinforces the whole, but in order to improve the compatibility with the outer synthetic resin, it is preferable to form appropriate irregularities on the surface, and the irregularities are formed by press processing. inner covering, physical irregularities due to press processing,
This can be done by sandblasting or the like.
この１１１０を使用する場合には、鍵山１３．１４の部
分を所定の形状に成形するすることによって行うが、こ
の部分には金属芯材１１が無いので成形は容易に行え、
この成形は予め射出成形によるもの、合鍵複製機による
加工であっても良い。When using this 1110, the key threads 13 and 14 are molded into a predetermined shape, but since there is no metal core material 11 in this part, the molding can be done easily.
This molding may be performed in advance by injection molding or by processing using a duplicate key duplicating machine.
次に、第３図に示す鍵２０の製造方法について説明する

２の先端に相当する部分にホルダー片２３を連接してお
き、所定の溝２４を設けるプレス加工を行う。Next, to explain the manufacturing method of the key 20 shown in FIG. 3, first, a metal core material 21 such as a stainless steel plate is formed into a predetermined shape.
A holder piece 23 is connected to a portion corresponding to the tip of the holder 2, and press working is performed to form a predetermined groove 24.
次に、ハンドリングマシンによって該金属芯材２１のホ
ルダー片２３の部分と該ホルダー片２３とは反対位置と
なる頭部（１！のホルダ一部に相当する部分）２５とを
掴んで直線状となした後、金型の中に入れて射出成形を
行う。Next, the holder piece 23 of the metal core 21 and the head 25 opposite to the holder piece 23 (corresponding to a part of the holder 1!) are grabbed by a handling machine and shaped into a straight line. After forming, it is placed in a mold and injection molded.
ここで、金属心材２１はハンドリングマシンによって直
線状に保持されているので、確実に所定の位置に保持で
きて、Ｉ！２０の厚み方向中心に配置されることになる
。Here, since the metal core material 21 is held in a straight line by the handling machine, it can be reliably held in a predetermined position and I! 20 at the center in the thickness direction.
所定の成形を終わった後、鍵部２２の先端２５ａにて金
属芯材２１を切り離し、先端の仕上げ加工を行うことに
よってｉ！２０が製造される。After completing the prescribed molding, the metal core material 21 is cut off at the tip 25a of the key part 22, and the tip is finished. 20 are manufactured.

好ましい。Figures 4 (A), (B), (C), and (D) show cross-sectional shapes of key parts to be inserted into the keyholes of various keys, and the hatched areas 26 to 30 in the figures indicate key threads, and The metal core materials 35 to 38 bent in this way are integrally molded, showing a state in which metal core materials 35 to 38 formed into a predetermined shape are disposed in the non-keyed portions 31 to 34 having an uneven cross section. This increases the strength of the key and allows it to withstand repeated normal use.Also, in the above example, the metal core material was placed at the center in the thickness direction of the plate, but it is placed closer to one side. In this case, it is preferable to appropriately form irregularities on the metal in order to increase the adhesion between the metal and the synthetic resin, and to use a material with a coefficient of thermal expansion as close as possible.
