【考案の詳細な説明】 この考案は例えば錠の挿入孔にカバーとして取り付ける
内筒キャップカバーの構造に関する。[Detailed Description of the Invention] This invention relates to the structure of an inner cylinder cap cover that is attached as a cover to an insertion hole of a lock, for example.

以下説明の都合上、例として自動車の錠の内筒キャップ
カバーについて説明する。For convenience of explanation, the inner cylinder cap cover of an automobile lock will be explained below as an example.

従来の内筒キャップカバーは第１図に示すように、錠の
内筒１に設けたキャップ２のキー挿入孔部３に、ばね４
を装着したカバー５が、カバーと一体の軸６を支点とし
て回動自在に装着されており、ばね４とカバー５とは別
体で形威されていた。As shown in Fig. 1, the conventional inner cylinder cap cover has a spring 4 inserted into the key insertion hole 3 of the cap 2 provided in the inner cylinder 1 of the lock.
A cover 5, on which the spring 4 and the cover 5 are mounted, is rotatably mounted around a shaft 6 integral with the cover, and the spring 4 and the cover 5 are separate bodies.

このため、部品数が多い事により故障の要因も増加し、
又、製作工数も多く手数を要していた。As a result, the number of failure factors increases due to the large number of parts.
In addition, the number of man-hours required for production was large and time-consuming.

この考案は上記にかんがみ、カバーとばねを一体に構成
し、部品数が削減され、製作工数が減少できる内筒キャ
ップカバーの提案を目的とする。In view of the above, the purpose of this invention is to propose an inner cylinder cap cover in which the cover and the spring are integrated, the number of parts can be reduced, and the number of manufacturing steps can be reduced.

この考案の実施例を図面に基づいて説明すると、第２図
は内筒キャップカバー５である。An embodiment of this invention will be described based on the drawings. FIG. 2 shows an inner cylinder cap cover 5. As shown in FIG.

この内筒キャップカバー５は、ばね弾性を有する例えば
ステンレス材等の板状部材から両端を略直交方向に屈曲
されて一端にカバ一部５ｂ、他端に係止部５ｃが形威さ
れ、さらにその屈曲部位にはカバ一部５ｂを係止部５ｃ
側へ復元可能に撓み可能とするうず巻部５ａが形威され
ている。The inner cylinder cap cover 5 is made of a plate-like member having spring elasticity, such as a stainless steel material, and is bent at both ends in substantially orthogonal directions to form a cover portion 5b at one end and a locking portion 5c at the other end. A cover part 5b is attached to a locking part 5c at the bent part.
A spiral portion 5a is formed so that it can be bent back to the side.

この内筒キャップカバー５は、第３図に示すように、係
止部５ｃが錠の内筒１に設けられた係止穴１ｂに装着さ
れて係止され、カバ一部５ｂが錠の内筒１に設けられた
キャップ２のキー挿入孔部３裏側周縁に当接されて配置
される。As shown in FIG. 3, this inner cylinder cap cover 5 is locked when the locking part 5c is attached to the locking hole 1b provided in the inner cylinder 1 of the lock, and the cover part 5b is locked inside the lock. It is placed in contact with the periphery of the back side of the key insertion hole 3 of the cap 2 provided on the cylinder 1.

このように構成された内筒キャップカバー５は、キー挿
入孔部３にキー７を挿入すると、上方に配置されている
カバ一部５ｂがキー７に押込まれて下方へ撓み、キー７
が抜かれると、うず巻部５ａの復元力によりカバ一部５
ｂが上方に回動し、カバ一部５ｂはその上方をキー挿入
孔部３裏側周縁に当接させた状態に復元され、錠の内筒
１内への水やほこりの侵入を防止できる。In the inner cylinder cap cover 5 configured as described above, when the key 7 is inserted into the key insertion hole 3, the cover part 5b disposed above is pushed into the key 7 and bent downward, so that the key 7
When the cover is pulled out, the restoring force of the spiral portion 5a causes the cover part 5 to
b rotates upward, and the cover part 5b is restored to the state in which its upper part is brought into contact with the back side periphery of the key insertion hole part 3, thereby preventing water and dust from entering into the inner cylinder 1 of the lock.

以上説明したように；この考案の内筒キャップカバーは
、ばね弾性を有する板状部材から両端を略直交方向に屈
曲されて一端にカバ一部、他端に係止部を形威し、さら
に屈曲部位にはカバ一部を係止部側へ復元可能に撓み可
能とするうず巻部を形成腰係止部が錠内部に設けられた
係止穴に係止させ、カバ一部をキー挿入孔部裏側周縁に
当接させて配置させることにより、部品数を減少できる
とともに、故障の発生要因を削減でき、さらに、製作工
数を削減でき、製作を簡素化できる等の効果を奏する。As explained above; the inner cylinder cap cover of this invention is made of a plate-like member having spring elasticity, both ends of which are bent in substantially orthogonal directions to form a part of the cover at one end and a locking part at the other end. A spiral part is formed at the bending part to allow the cover to bend back toward the locking part.The waist locking part locks into the locking hole provided inside the lock, and part of the cover is inserted into the key. By arranging it in contact with the periphery of the back side of the hole, the number of parts can be reduced, the causes of failure can be reduced, and furthermore, the number of manufacturing steps can be reduced and manufacturing can be simplified.
