【発明の属する技術分野】
本発明は機器本体の開口部を開閉する蓋装置に関するものである。
【０００２】
【従来の技術】
カメラなどの機器本体には、電池室の開口部を開閉する蓋や、記録媒体のカードを差し込む開口部を開閉する蓋などの蓋装置が設けられている。
【０００３】
図９（ａ）はデジタルカメラのカメラ本体１の底部２に設けられた電池室３の開口部を開閉する蓋装置を表している。
電池室３の開口部を開閉する電池蓋４は軸５によってカメラ本体１に取り付けられている。電池蓋４には、カメラ本体１に係合するロックレバー６が組み込まれている。このロックレバー６は、カメラ本体１に係合する位置に突出するように圧縮ばね７によって常時付勢されており、開いた電池蓋４を閉じる際には、電池蓋４を閉塞する方向に回動させるだけで、ロックレバー６がカメラ本体１に係合してロックされる。
【０００４】
電池室３にセットされた電池８は、電池室の奥側に取り付けられたバッテリ端子９のばね性によって前記電池蓋４の内側に取り付けられた電池接片１０の側に付勢されて保持されている。
【０００５】
電池室３にセットされている電池８を取り出す際には、ロックレバー６を前記圧縮ばね７に抗して後退させてカメラ本体１との係合を解除すると、図９（ｂ）に示すように電池蓋４はバッテリ端子９のばね性によって開放する方向に回動する。
【０００６】
このような蓋装置は、特許文献１に記載されている。
【０００７】
【特許文献１】
特開昭５８−６４７５３号公報の第３図，第４図
【０００８】
【発明が解決しようとする課題】
しかし、このような従来の構成では、電池室３に電池をセットされていない状態で電池蓋を開く場合には、電池蓋４を開放する方向に作用していた前記バッテリ端子９のばね性が作用しない状態になっているため、下記のツーアクションが必要である。
【０００９】
第１アクション
ロックレバー６を前記圧縮ばね７に抗して後退させる。
第２アクション
第１アクションの状態を維持しながら電池蓋を開放方向に回動させる。
【００１０】
なお、片手でカメラ本体を持った状態で、もう一方の手でロックレバー６を操作しているため、不確実な操作になって、実際は電池蓋４を下に向けての操作を強いられるものである。
【００１１】
本発明は、電池室に電池をセットされていない状態で電池蓋を開く場合にも、片手操作で確実に開閉できる蓋装置を提供することを目的とする。
【００１２】
【課題を解決するための手段】
本発明の電子機器の蓋装置は、機器本体の開口部を開閉する扉本体に組み込んだロックレバーに係合フックを設け、前記機器本体の側には、扉本体から突出する方向に付勢された前記ロックレバーを前記付勢に抗して係合が外れる方向に移動させた状態で前記係合フックが係合して前記ロックレバーの突出方向への移動を規制する被係合部を設けたことを特徴とする。
【００１３】
この構成によると、扉本体の側のロックレバーにも受けられた係合フックが、前記機器本体の側の被係合部に係合した状態では、ロックレバーを前記付勢に抗して機器本体との係合が外れる方向に移動させる力を解除してもロックレバーが元の位置に復帰しないので、扉本体を確実に開放できる。
【００１４】
本発明の請求項１記載の電子機器の蓋装置は、機器本体の開口部を開閉するように一端が回動自在に支持された扉本体に、前記扉本体から突出する方向に付勢され先端の突出部分が機器本体に係合して前記扉本体を閉塞位置にロックするロックレバーを組み込んだ蓋装置であって、扉本体の前記ロックレバーの基端部に弾性変形する係合フックを設け、前記機器本体の側には前記付勢に抗してロックレバーを移動させた状態で前記係合フックが係合して前記ロックレバーの突出方向への移動を規制する被係合部を設けたことを特徴とする。
【００１５】
本発明の請求項２記載の電子機器の蓋装置は、請求項１の構成に加えて、扉本体の前記一端と前記機器本体の間に扉本体を開放方向へ付勢する付勢手段を設けたことを特徴とする。
【００１６】
この構成によると、ロックレバーを前記付勢に抗して係合が外れる方向に移動させる力を解除するだけで、付勢手段によって扉本体を開放できる。
本発明の請求項３記載の電子機器の蓋装置は、扉本体の前記ロックレバーの基端部に係合フックを設け、前記機器本体の側には前記付勢に抗してロックレバーを移動させた状態で弾性変形して前記係合フックが係合して前記ロックレバーの突出方向への移動を規制する被係合部を設けたことを特徴とし、請求項１の構成ではロックレバーの係合フックが弾性変形したのに対して、この請求項３の構成では機器本体の側の被係合部が弾性変形して同様の効果を達成する。
【００１７】
本発明の請求項４記載の電子機器の蓋装置は、請求項１において、前記ロックレバーは、扉本体から突出した状態に付勢され先端に前記機器本体に係合するフックが形成されたフック本体と、前記フック本体に係合して前記フック本体と同じ方向に付勢されるとともに前記扉本体の基端部の側には前記機器本体の側に設けられた被係合部に係合可能な係合フックが形成されたロックレバー本体とで構成され、フック本体はロックレバー本体とは独立して前記付勢に抗して移動できるようにしたことを特徴とする。
【００１８】
【発明の実施の形態】
以下、本発明の実施の形態を図１〜図８に基づいて説明する。
なお、ここではデジタルカメラの電池室の蓋装置の場合を例に挙げて説明する。
【００１９】
図１は電池室３の電池蓋１１を閉じた状態を示している。
基端部が軸５によって枢支された扉本体としての電池蓋１１には、圧縮ばね７によって突出する方向に付勢されたロックレバー１２が組み込まれており、この図１ではロックレバー１２の先端のフック１３が、機器本体としてのカメラ本体１に係合して閉塞状態になっている。
【００２０】
詳しくは、電池蓋１１は図６に示すように、電池蓋本体１４の裏面を覆うように電極板１５をビス１６，１７で取り付けられ、電池蓋本体１４と電極板１５とで形成される空間にロックレバー１２と圧縮ばね７が組み込まれている。電極板１５の一部には、カメラ本体１に取り付けられる支持部材１８に前記軸５によって連結される連結部１９が形成されている。さらに、電極板１５と支持部材１８との間には、電池蓋１１を開放する方向に付勢する付勢手段としてのばね２０が設けられている。
【００２１】
ロックレバー１２は、合成樹脂製のロックレバー本体２１とこの底部に取り付けられて一体にスライドするフック本体２２とで構成されている。
図７（ａ）は図６のＣ−Ｃ′方向から組み立て状態のロックレバー１２を見た図で、ロックレバー本体２１の表面には図７（ａ）に示すように操作する指が引っ掛かるように突出した指掛け２３が形成され裏面の基端部には係合フック２４が一体成型されている。
【００２２】
図７（ｂ）は図７（ａ）のＤ−Ｄ′断面図で、フック本体２２の表面には、ロックレバー本体２１の横に張り出した腕部２５が係合する凹部２６が形成されている。なお、フック本体２２の凹部２６の長さＬはロックレバー本体２１の腕部２５の幅Ｗよりも長く、フック本体２２の凹部２６の端部にロックレバー本体２１の腕部２５が係合した状態（図７（ａ））では、ロックレバー本体２１は圧縮ばね７の付勢力によってフック本体２２の移動方向へ一体に移動する。また、フック本体２２はロックレバー本体２１が停止していても凹部２６の前記長さＬの範囲内でロックレバー本体２２に対して出退方向にスライド移動できる。
【００２３】
図８（ａ）（ｂ）は図６を矢印Ｅ−Ｅ′の方向から見た組み立て状態を示している。
図８（ａ）に示すように、圧縮ばね７は、電池蓋本体１４の裏面に形成された突起３０とフック本体２２の基端部との間に介装されており、図１に示すように圧縮ばね７の付勢力によってフック本体２２のフック１３が電池蓋１１から突出した状態では、フック本体２２の凹部２６の端部２７に腕部２５が係合したロックレバー本体２１は、図１（ａ）では圧縮ばね７の付勢力で紙面の右側に付勢されている。なお、ロックレバー本体２１は電池蓋本体１４に当接して移動が規制されており、フック本体２２はこのロックレバー本体２１に係合して規定量以上に電池蓋本体１４から外部に突出しないように構成されている。
【００２４】
また、カメラ本体１には、ロックレバー１２の係合フック２４に対応した位置に被係合部としての凸部２８が形成されている。ロックレバー１２の係合フック２４とカメラ本体１の凸部２８との位置関係は、電池蓋１１を閉じた図１に示す状態では、係合フック２４の先端が凸部２８に乗り上げない位置に設定されている。
【００２５】
電池蓋１１を開放しようとして、人差し指でロックレバー本体２１の指掛け２３を押さえて圧縮ばね７の付勢に抗して後退（図１の紙面の左側）させると、ロックレバー１２の係合フック２４が図２に示すようにカメラ本体１の凸部２８に乗り上げ始めて係合フック２４が仮想線位置から実線位置のように弾性変形し、圧縮ばね７の付勢に抗してさらにロックレバー１２が後退させられると、弾性変形した係合フック２４が図３に示すように凸部２８を乗り越えて凸部２８の段部２９に係合する。
【００２６】
この図３に示すように係合フック２４が凸部２８の段部２９に係合した状態では、フック本体２２の先端のフック１３は、カメラ本体１とは係合しない位置に後退している。また、係合フック２４が凸部２８の段部２９に係合しているこの状態では、圧縮ばね７による付勢は、係合フック２４を凸部２８の段部２９に押し付けるように作用しているため、ロックレバー１２を圧縮ばね７の付勢に抗して後退させようとする操作力を解除してもロックレバー１２は、図３に示すように後退した位置に維持される。
【００２７】
図３に示す状態でロックレバー１２から人差し指を離すと、電池蓋１１はばね２０の付勢力によって図４に示す状態を経て図５に示す位置へ開放される。このときの電池蓋１１の回動によって、係合フック２４と凸部２８との係合が自動解除され、ロックレバー１２は圧縮ばね７によってフック１３が電池蓋１１から突出した状態に復帰する。
【００２８】
このように、電池室３に電池が入っていない状態であっても、ロックレバー１２を押さえてスライドさせて指を離すワンアクションだけで電池蓋１１が確実に開く。さらに、電池蓋１１が開いた状態では上記のように電池蓋１１からロックレバー１２が突出した状態に復帰しているので、電池蓋１１を図１に示す状態に回動させる１アクションだけでロックレバー１２のフック１３がカメラ本体１に係合して電池蓋１１を閉塞位置に保持できる。
【００２９】
詳しくは、フック本体２２は図８（ｂ）に示すように、前記凹部２６の範囲内でロックレバー本体２１とは独立してスライド移動できるため、カメラ本体１がフック１３に衝突すると、フック本体２２はロックレバー本体２１とは独立して確実に後退する方向に一旦スライドして突出状態に復帰することができ、ロックレバー１２のフック１３がカメラ本体１に係合確実に係合する。
【００３０】
この実施の形態では、電極板１５と支持部材１８との間には、電池蓋１１を開放する方向に付勢するばね２０を設けたが、このばね２０を設けなかった場合であっても図３に示すようにフック１３が凸部２８に係合した状態でカメラ本体１の底部２を下方に向けるだけで、電池蓋１１は自重で確実に開放される。
【００３１】
なお、上記の実施の形態ではロックレバー１２の側の係合フック２４が弾性変形してカメラ本体１の側の凸部２８に係合してロックレバー１２のフック１３が突出することを規制したが、ロックレバー１２を移動させた状態でロックレバー１２の側のフック１３がカメラ本体１の側の凸部２８に当接してカメラ本体１の側の凸部２８が弾性変形して両者が係合するように構成しても、同様に実現できる。
【００３２】
上記の各実施の形態ではカメラの電池室の場合を例に挙げて説明したが、記録媒体のカードを差し込む開口部を開閉する蓋装置などにも同様に実施できる。
【００３３】
【発明の効果】
以上のように本発明によると、機器本体の開口部を開閉する扉本体に組み込んだロックレバーに係合フックを設け、前記機器本体の側には、扉本体から突出する方向に付勢された前記ロックレバーを前記付勢に抗して係合が外れる方向に移動させた状態で前記係合フックが係合して前記ロックレバーの突出方向への移動を規制する被係合部を設けたため、扉本体の側のロックレバーにも受けられた係合フックが前記機器本体の側の被係合部に係合した状態では、ロックレバーを前記付勢に抗して機器本体との係合が外れる方向に移動させる力を解除してもロックレバーが元の位置に復帰しないので、扉本体を片手操作で確実に開閉できる。

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
Here, a case of a lid device for a battery compartment of a digital camera will be described as an example.
[0019]
FIG. 1 shows a state where the battery cover 11 of the battery chamber 3 is closed.
A lock lever 12 urged in a direction to protrude by a compression spring 7 is incorporated in a battery lid 11 as a door body whose base end is pivotally supported by a shaft 5, and in FIG. The hook 13 at the tip is engaged with the camera body 1 as the device body and is in a closed state.
[0020]
Specifically, as shown in FIG. 6, the battery cover 11 has an electrode plate 15 attached with screws 16 and 17 so as to cover the back surface of the battery cover body 14, and a space formed by the battery cover body 14 and the electrode plate 15. The lock lever 12 and the compression spring 7 are incorporated in the first embodiment. At a part of the electrode plate 15, a connecting portion 19 connected to the support member 18 attached to the camera body 1 by the shaft 5 is formed. Further, a spring 20 is provided between the electrode plate 15 and the support member 18 as urging means for urging the battery lid 11 in the opening direction.
[0021]
The lock lever 12 includes a lock lever main body 21 made of a synthetic resin and a hook main body 22 attached to the bottom and sliding integrally.
FIG. 7A is a view of the lock lever 12 in the assembled state from the CC ′ direction of FIG. 6, and a finger operated as shown in FIG. An engaging hook 24 is integrally formed at the base end of the rear surface.
[0022]
FIG. 7B is a cross-sectional view taken along the line DD ′ of FIG. 7A. A recess 26 is formed on the surface of the hook main body 22 so that the arm 25 protruding laterally of the lock lever main body 21 is engaged. I have. The length L of the concave portion 26 of the hook body 22 is longer than the width W of the arm portion 25 of the lock lever body 21, and the arm portion 25 of the lock lever body 21 is engaged with the end of the concave portion 26 of the hook body 22. In the state (FIG. 7A), the lock lever main body 21 moves integrally in the moving direction of the hook main body 22 by the urging force of the compression spring 7. Further, even when the lock lever main body 21 is stopped, the hook main body 22 can slide in the retracting direction with respect to the lock lever main body 22 within the range of the length L of the concave portion 26.
[0023]
FIGS. 8A and 8B show the assembled state of FIG. 6 viewed from the direction of arrows EE ′.
As shown in FIG. 8A, the compression spring 7 is interposed between the projection 30 formed on the back surface of the battery lid main body 14 and the base end of the hook main body 22, and as shown in FIG. When the hook 13 of the hook main body 22 protrudes from the battery lid 11 by the urging force of the compression spring 7, the lock lever main body 21 in which the arm 25 engages with the end 27 of the concave portion 26 of the hook main body 22, as shown in FIG. In (a), the urging force of the compression spring 7 is applied to the right side of the drawing. The movement of the lock lever main body 21 is restricted by contacting the battery lid main body 14, and the hook main body 22 is engaged with the lock lever main body 21 so that the hook main body 22 does not protrude from the battery lid main body 14 beyond a specified amount. Is configured.
[0024]
Further, the camera body 1 has a projection 28 as a portion to be engaged at a position corresponding to the engagement hook 24 of the lock lever 12. The positional relationship between the engagement hook 24 of the lock lever 12 and the projection 28 of the camera body 1 is such that the tip of the engagement hook 24 does not ride on the projection 28 in the state shown in FIG. Is set.
[0025]
When the user attempts to open the battery cover 11 and presses the finger hook 23 of the lock lever main body 21 with the forefinger to retract (to the left in FIG. 1) against the bias of the compression spring 7, the engagement hook 24 of the lock lever 12 As shown in FIG. 2, the engaging hook 24 begins to ride on the convex portion 28 of the camera body 1 and elastically deforms from the imaginary line position to the solid line position, and the lock lever 12 is further pressed against the bias of the compression spring 7. When retracted, the elastically deformed engaging hook 24 gets over the convex portion 28 and engages with the step portion 29 of the convex portion 28 as shown in FIG.
[0026]
As shown in FIG. 3, when the engagement hook 24 is engaged with the step 29 of the projection 28, the hook 13 at the tip of the hook body 22 is retracted to a position where it is not engaged with the camera body 1. . Further, in this state where the engaging hook 24 is engaged with the step 29 of the projection 28, the biasing by the compression spring 7 acts to press the engaging hook 24 against the step 29 of the projection 28. Therefore, even if the operating force for retracting the lock lever 12 against the bias of the compression spring 7 is released, the lock lever 12 is maintained at the retracted position as shown in FIG.
[0027]
When the index finger is released from the lock lever 12 in the state shown in FIG. 3, the battery lid 11 is opened to the position shown in FIG. 5 through the state shown in FIG. The rotation of the battery cover 11 at this time automatically releases the engagement between the engagement hook 24 and the projection 28, and the lock lever 12 returns to the state where the hook 13 projects from the battery cover 11 by the compression spring 7.
[0028]
As described above, even when the battery is not in the battery chamber 3, the battery cover 11 is reliably opened only by one action of pressing and sliding the lock lever 12 and releasing the finger. Further, when the battery cover 11 is open, the lock lever 12 has returned to the state in which the lock lever 12 protrudes from the battery cover 11 as described above. Therefore, the battery cover 11 can be locked by only one action of rotating the battery cover 11 to the state shown in FIG. The hook 13 of the lever 12 engages with the camera body 1 to hold the battery cover 11 in the closed position.
[0029]
More specifically, since the hook body 22 can slide independently of the lock lever body 21 within the range of the concave portion 26 as shown in FIG. Reference numeral 22 is independent of the lock lever main body 21 and can be slid once in the retreating direction to return to the projected state, and the hook 13 of the lock lever 12 is securely engaged with the camera main body 1.
[0030]
In this embodiment, a spring 20 is provided between the electrode plate 15 and the support member 18 to urge the battery cover 11 in the opening direction. However, even if the spring 20 is not provided, As shown in FIG. 3, the battery cover 11 is reliably opened by its own weight only by turning the bottom 2 of the camera body 1 downward with the hook 13 engaged with the projection 28.
[0031]
In the above embodiment, the engagement hook 24 on the side of the lock lever 12 is elastically deformed to engage with the projection 28 on the side of the camera body 1 to restrict the protrusion of the hook 13 of the lock lever 12. However, in a state where the lock lever 12 is moved, the hook 13 on the side of the lock lever 12 abuts on the protrusion 28 on the side of the camera body 1, and the protrusion 28 on the side of the camera body 1 is elastically deformed, so that both are engaged. Even if they are configured to match, the same can be realized.

【The invention's effect】
As described above, according to the present invention, an engagement hook is provided on the lock lever incorporated in the door body that opens and closes the opening of the device main body, and is urged toward the device main body in a direction protruding from the door main body. Because the engaging hook is engaged in a state where the lock lever is moved in a direction in which the lock lever is disengaged against the urging force, and an engaged portion that regulates the movement of the lock lever in the protruding direction is provided. In a state where the engagement hook received also by the lock lever on the door body side is engaged with the engaged portion on the device body side, the lock lever engages with the device body against the bias. Since the lock lever does not return to the original position even if the force for moving the door in the direction in which the door is released is released, the door body can be reliably opened and closed by one-handed operation.
