Description

本発明は一つ又は複数個の鍵を収納し、財布やポケット、ハンドバック等に入れて携帯しやすく、且つ簡単な鍵操作ができる様に工夫したフラットでコンパクトなカード型のキーホルダーである。The present invention is a flat and compact card-type key holder that stores one or a plurality of keys, is easy to carry in a wallet, a pocket, a handbag or the like and can be easily operated.

従来のカード型キーホルダーは鍵をホルダーに対しスライド又は水平回転させて鍵本体部を突出させる方法が多く構成が複雑であった（例えば、特許文献１及び２参照。）。また、市販の一般的な鍵をそのまま使用するのではなくそれを加工したり、或いは専用の特殊な形状をした鍵を必要としているものがある（例えば、特許文献３及び４参照。）。
特許３４６７６４５特開平１１−２４７５０２特許２８３７６２６特許２８９６４９０ Conventional card-type key holders have a complicated structure in which a key is slid or horizontally rotated with respect to the holder to project the key body (see, for example, Patent Documents 1 and 2). In addition, there is a case where a commercially available general key is not used as it is, but it is processed or a special key having a special shape is required (for example, see Patent Documents 3 and 4).

従来のキーホルダーは使用時に鍵をホルダーよりスライド又は水平回転させながら取り出す方式が多く、構成が複雑でコストがかかる。また、市販の鍵をそのまま使用するのではなく加工を加えたり、専用の特殊な形状を必要としている場合が多い。また、照明ライト付きのキーホルダーもあるがスイッチを設けたり構成が複雑でコストがかかる。Conventional key holders often have a method of taking out a key while sliding or horizontally rotating from the holder during use, and the configuration is complicated and expensive. Further, in many cases, a commercially available key is not used as it is, but processing is added or a special special shape is required. In addition, there is a key holder with an illumination light, but a switch is provided and the structure is complicated and expensive.

キーホルダー本体は図１の様に本体部１，本体回転部２及び３の３体から構成されている。本体回転部２，及び３には鍵６が固定され、それぞれは回転支点部５を中心として１８０度立体的に回転できる様にした。１８０度回転させると、鍵６は鍵本体部６ａのみが突出する状態となり（図２参照）そのまま鍵穴に挿入し施錠操作が出来る。また、本体部１と本体回転部２，３の間には弾性部材７を設け、鍵を使用しない通常の状態の時はそれぞれ互いに引き合いながら図１の様なフラットな状態を保つ。カードホルダーを折り曲げて鍵を使用した後に、本体回転部２を離すと弾性部材７の張力により自動的に図１の状態に復帰するようにした。また、ライト付きキーホルダーにおいては、本体回転部２、３を１８０度回転させると自動的にライトが点灯する様にし、煩わしいスイッチ操作をなくした。As shown in FIG. 1, the key holder main body is composed of a main body portion 1 and main body rotating portions 2 and 3. A key 6 is fixed to the main body rotation parts 2 and 3 so that each of them can be rotated three-dimensionally around the rotation fulcrum part 5. When the key 6 is rotated 180 degrees, only the key body 6a protrudes (see FIG. 2), and the key 6 can be inserted into the keyhole as it is and can be locked. Further, an elastic member 7 is provided between the main body 1 and the main body rotating parts 2 and 3, and in a normal state where the key is not used, the flat state as shown in FIG. 1 is maintained while attracting each other. After the card holder is bent and the key is used, when the main body rotating portion 2 is released, the state automatically returns to the state shown in FIG. In addition, in the key ring with a light, the light is automatically turned on when the main body rotating portions 2 and 3 are rotated 180 degrees, thereby eliminating troublesome switch operations.

市販の一般的な形状の鍵をほとんど使用する事ができる。また、キーホルダーから鍵を取り出す操作を従来のスライドや回転の様な複雑な水平動作ではなく、単純な立体的折り曲げ動作の構成としてコスト削減を図った。単純な折り曲げ操作と、使用後は内蔵してある弾性体により元のフラットな状態に自動復帰する機構としたため施錠時の鍵の出し入れ操作が片手で簡単にでき操作性に優れる。且つ、機構が単純なため薄型化が図れる。又、照明機能を付加する事により、夜間の施錠操作やそれ以外の対物照明等に便利である。照明を点滅させる専用スイッチが無く操作が簡単で利便性が高く、しかも部品コストを削減できる効果が大きい。Most commercially available keys with a general shape can be used. In addition, the operation of taking out the key from the key holder is not a complicated horizontal movement like conventional slide and rotation, but a simple three-dimensional bending operation, thereby reducing costs. A simple folding operation and a mechanism that automatically returns to its original flat state after use with the built-in elastic body makes it easy to insert and remove the key during locking with one hand and excels in operability. Moreover, since the mechanism is simple, the thickness can be reduced. Also, by adding an illumination function, it is convenient for nighttime locking operations and other objective illuminations. There is no dedicated switch to blink the light, it is easy to operate and highly convenient, and the effect of reducing the cost of parts is great.

（イ）キーホルダー本体は図１の様に本体部１，本体回転部２及び３の３体から構成されている。それぞれは裏面において、片面粘着材を塗布し容易に折り曲げる事のできる薄いシート状の部材４で接合されており、それぞれの接点部である回転支点部５を支点として１８０度立体的に回転可能になっている。
（ロ）鍵６は本体回転部２，３の凹部である鍵固定部２ａ、３ａに両面粘着部材又は機械的固定部材で結合される。鍵を固定して本体回転部２を１８０度回転させ施錠を行う状態が図２である。
（ハ）図３ＡＡ断面図において、本体部１と本体回転部２，３の間には弾性部材７を配置し、それぞれ互いに引き合いながら図１の様なフラットな状態を維持させている。本体回転部２，３を１８０度回転した状態では（図４参照）その弾性部材７は戻ろうとする張力が働く、その為、鍵操作後に本体回転部２の保持操作を解除すると弾性部材７の張力により自動的に図１の状態に復帰する。
（ニ）図５は照明装置を装備したキーホルダーの鍵収納時状態での外観斜視図である。図６は本体回転部２を１８０度立体的に回転し鍵を突出させた状態の斜視図であり照明部材の点灯の状態を表している。図７は照明装置を装備したキーホルダーの内部平面図である。本体回転部２の内部には弾性体であるトーションバネ９が配置されており、その一端にテンションワイヤー１０が結ばれている。テンションワイヤー１０の他方の一端は本体部１に固定されており、トーションバネ９の時計方向の回転力により互いに引き合ってキーホルダーをフラットな状態に維持している。
本体部１には電池１１が２個直列に配置されており、プラスの電圧を取り出すリード線Ａ１２は本体回転部２の照明部品の片側の端子に接続されている。マイナスの電圧を取り出すリード線Ｂ１３は本体回転部２に装備してある導電板Ａ１４にハンダ付けされている。照明部品８の他方の端子には導通板Ｂ１５がハンダ付けされてそれぞれ図７の様な形状をなしている。
導通板Ｂ１５は本体回転部２の内部に固定されている、導通板Ａ１４は一端のみが固定され他の一端は拘束されていない為、ある領域をバネ性を持って撓む事ができる。
キーホルダーが通常のフラットな状態の時は、トーションバネ９の先端に形成されている押上げ部９ａにより導電板Ａ１４は撓んだ状態で、導電板Ｂ１５との接点部１６は乖離された状態となり電気的導通は絶たれている。
キーホルダーを立体的に１８０度折り畳むと一端を本体部１に固定されているテンションワイヤー１０がトーションバネ９を半時計方向に撓ませ、同時に押上げ部９ａも同方向に移動する。導通板Ａ１４もこれに追従して移動し導電板Ａの撓み力により接点部１６が互いに圧接して導通状態となり（図８参照）、その結果照明部品８が通電状態となり点灯する。また、施錠後に本体回転部２の保持操作を解除するとトーションバネ９の張力により自動的に元のフラットな状態に復帰する。(A) As shown in FIG. 1, the key holder main body is composed of a main body 1 and main body rotating parts 2 and 3. Each is joined on the back by a thin sheet-like member 4 that can be easily folded by applying a single-sided adhesive material, and can be rotated three-dimensionally 180 degrees with the rotation fulcrum 5 as a fulcrum. It has become.
(B) The key 6 is coupled to the key fixing portions 2a and 3a which are the concave portions of the main body rotating portions 2 and 3 by a double-sided adhesive member or a mechanical fixing member. FIG. 2 shows a state in which the key is fixed and the main body rotating unit 2 is rotated 180 degrees to perform locking.
(C) In the cross-sectional view of FIG. 3AA, an elastic member 7 is arranged between the main body 1 and the main body rotating parts 2 and 3, and the flat state as shown in FIG. 1 is maintained while attracting each other. When the main body rotating portions 2 and 3 are rotated 180 degrees (see FIG. 4), the elastic member 7 is subjected to tension to return, and therefore when the holding operation of the main body rotating portion 2 is released after the key operation, the elastic member 7 The state of FIG. 1 is automatically restored by the tension.
(D) FIG. 5 is an external perspective view of the key holder equipped with the illumination device in a state where the key is stored. FIG. 6 is a perspective view of a state in which the main body rotating unit 2 is rotated three-dimensionally by 180 degrees to project the key, and shows a lighting state of the illumination member. FIG. 7 is an internal plan view of a key holder equipped with a lighting device. A torsion spring 9, which is an elastic body, is disposed inside the main body rotation unit 2, and a tension wire 10 is connected to one end thereof. The other end of the tension wire 10 is fixed to the main body 1 and is attracted to each other by the clockwise rotational force of the torsion spring 9 to keep the key holder flat.
Two batteries 11 are arranged in series in the main body 1, and a lead wire A <b> 12 for taking out a positive voltage is connected to a terminal on one side of the lighting component of the main body rotating portion 2. A lead wire B13 for extracting a negative voltage is soldered to a conductive plate A14 provided in the main body rotation unit 2. A conductive plate B15 is soldered to the other terminal of the lighting component 8 to have a shape as shown in FIG.
Since the conducting plate B15 is fixed inside the main body rotating part 2, the conducting plate A14 is fixed at one end and is not restrained at the other end, so that a certain region can be bent with a spring property.
When the key holder is in a normal flat state, the conductive plate A14 is bent by the push-up portion 9a formed at the tip of the torsion spring 9, and the contact portion 16 with the conductive plate B15 is separated. Electrical continuity is cut off.
When the key holder is folded 180 degrees in three dimensions, the tension wire 10 having one end fixed to the main body 1 bends the torsion spring 9 counterclockwise, and at the same time, the push-up portion 9a moves in the same direction. The conductive plate A14 also moves following this, and the contact portions 16 are pressed against each other by the bending force of the conductive plate A to be in a conductive state (see FIG. 8). As a result, the lighting component 8 is energized and lights up. When the holding operation of the main body rotating unit 2 is released after locking, the original flat state is automatically restored by the tension of the torsion spring 9.
