Description

【0001】
【発明の属する技術分野】
本発明は、ディジタルカメラなどの電池収納部の電池蓋のロック機構に関する。
【0002】
【従来の技術】
ディジタルカメラなどでは電池収納は操作性の観点から簡単に行えることが必要である。
そこで、電池蓋を閉じる機構として最も一般的なものとしては、ロック爪にバネ習性を与え、蓋を閉じたときロック爪が本体の一部に引っ掛かりロックする方式が用いられている。
今日ではディジタルカメラに代表されるように消費電力の大きい製品が多く出回っている。
【0003】
【発明が解決しようとする課題】
そのため電源として単三電池を4個使用するものがディジタルカメラを始めとして多くの機種に採用されるようになってきている。
単三電池を4個用いた場合、電池の電極に用いているバネ接片の反力のトータルが大きなものになる。そのため、上記従来のロック機構では落下などで衝撃が与えられた場合、ロック爪が外れてしまうという問題が顕在化している。
【0004】
図1はディジタルカメラの電池収容部における電池蓋ロック機構の一例を示す斜視図である。
ディジタルカメラボディ1の電池収納部9に4個の単三電池4が収容されている。電池蓋2の端部は軸7によりディジタルカメラボディー1に回転可能に取り付けられている。電池蓋2には先端にロック爪3bを有するロックレバー3がスライド可能に取り付けられている。
【0005】
電池蓋2の裏側には単三電池4の電極に接続する接片(図示されていない)が設けられ、さらに電池収納部9の底部にはコイルバネ接片6が配置されている。電池蓋2の上面を押すと、電池蓋2の裏側の接片が電池を押し、さらに電池蓋2を押し込むことによりロックレバー3のロック爪3bがボディより突出している係止部5に引っ掛かりロック状態となる。
【0006】
図2はロックレバーのロック爪が係止部に係合しロックされる動作を説明するための断面図である。
想像線(二点鎖線)で示すように電池蓋2を閉じていくと、ロックレバー3のロック爪3bの傾斜背面3eは係止部5の角部5bに突き当たる。さらに押し込むと、ロックレバー3はコイルバネ12に抗して右方向に移動するため、ロック爪3bの先端部は係止部5の先端に当たりながら下降し、係止部5の先端の下部に達するとコイルバネ12の付勢力により図3に示すように係止部5の係止面5bにロック爪3bの内面3dが係止する。
【0007】
コイルバネ接片6や電池蓋裏面の接片の反力により電池蓋2を上方向に押し上げようとする力が働くため、ロック爪3bが係止した状態ではロック爪3bの内面が係止部5の係止面に押し付けられ電池蓋2がガタ付くことはなくロックされる。ロックを解除する場合は、解除ノブ3aをコイルバネ12に抗して右方向にスライドさせることにより、ロック爪3bは係止部5より外れ電池蓋2を開くことができる。
【0008】
図6に従来のロックレバーと係止部の係止状態を示す。
単三電池が4個収容されて電池の接片で押されるトータルの反力14が大きい場合には、ロック爪3bおよびロックレバー3が図6に示すように反り、係止部5の角部5aがロック爪3bの上面の一点に圧接する状態となる。
このため上述したように衝撃などにより電池蓋が簡単に外れるという問題が生ずる。
本発明の課題は上記問題を解決するもので、ディジタルカメラ等に例えば4個の単三電池が用いられ、電池蓋を押す反力が大きい場合でも落下衝撃や乱暴な取扱いにより電池蓋のロックが外れることがないようにした電池蓋のロック機構を提供することにある。
【0009】
【課題を解決するための手段】
前記課題を解決するために本発明による電池蓋のロック機構は、一端が枢着された電池蓋に、先端にロック爪を有し移動習性が与えられているロックレバーをスライド可能に取付け、前記電池蓋を閉じるとき、前記ロック爪の傾斜背面がボディ側の係止部に当たり、前記移動習性に抗して前記ロックレバーがわずかにスライドして戻ることにより前記ロック爪の係止内面が前記係止部の係止面に係止すると同時に電池に接続するバネ性接片による反力により前記ロック爪の係止内面が前記係止部の係止面を押し付けてロックする電池蓋のロック機構において、前記ロック爪の係止内面の角度を前記係止部の係止面に対し15°±10°傾けるように構成してある。
【0010】
上記構成によれば、ロック爪の内面は係止部に係止時、係止部の係止面と面接触で接するようになり、衝撃が加わっても簡単に外れることはない。
【0011】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態を詳しく説明する。
図3は本発明による電池蓋のロック機構の実施の形態を示す図で、ロックレバーの形状を示したものである。
ロック機構は図1,図2と同じ構造であり、ロックレバーのロック爪の形状を図3のようにしてある。
係止部5の係止面5aに対し、ロックレバー8の内面の角度を15°±10°にしてある。
【0012】
図4は、図3の形状にしたときのロック爪と係止部との係合状態を示している。電池の接片の大きな反力が加わると、ロックレバー8は変形するが、その結果ロック爪8の内面8bと係止部5の係止面5aとは面接触状態となる。
このように面接触状態になると、例えば落下衝撃等が加わっても電池蓋が外れることはない。
本件発明者は、図3の形状で落下衝撃試験を行った結果、衝撃により電池蓋は開くことがないことを確認できた。
落下衝撃試験は、カメラを所定の高さから落下させ、これを所定回数繰り返すもので、ロック爪を係止した結果、図6になるような従来の形状では所定の回数落下を繰り返すうちに電池蓋が開くことがあったが、本発明によるロック機構のロック爪形状では一度も開くことはないという結果が得られた。
【0013】
図5は、ストラップ設置位置とロック機構の関係を説明するための斜視図である。止め金具10をディジタルカメラボディ1の電池収容部側の角に設け、ストラップ11で保持する場合、ディジタルカメラボディ1の自重によりディジタルカメラボディ1の側面は矢印13の方向に引っ張られる。そのため、ロックレバーのロック爪と係止部の係止量が少なくなる。電池蓋ロック機構に対し、このような位置にストラップ11を設置するのは好ましくない。しかしながら、ロック爪の形状を本発明のように構成すれば、ストラップを設ける位置は図5の位置でも良く、カメラ設計上でストラップ取付位置の制約はなくなる。
図1,図2の例はロックレバーが1つの場合を説明したが、1つでは不十分な場合、2個数以上設けても同様に適用できるものである。
【0014】
【発明の効果】
以上、説明したように本発明は、係止部に係止するロックレバーのロック爪の内面の傾きを係止部の係止面に対し、15°±10°とすることにより、例えば単三電池が4個収納されて電池接片の反力が大きい場合、ロック爪の内面は面接触で係止部の係止面に係合するように構成されているので、本体に衝撃が加わったり、乱暴な取扱いをしたりしても、電池蓋は簡単に開くことないという効果が得られる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lock mechanism for a battery cover of a battery storage unit such as a digital camera.
[0002]
[Prior art]
In a digital camera or the like, it is necessary that the battery can be easily stored from the viewpoint of operability.
Therefore, the most common mechanism for closing the battery cover is a method in which the lock claw is provided with a spring behavior, and when the cover is closed, the lock claw is hooked on a part of the main body and locked.
Today, there are many products with large power consumption, such as digital cameras.
[0003]
[Problems to be solved by the invention]
Therefore, a device using four AA batteries as a power source has been adopted by many models including a digital camera.
When four AA batteries are used, the total reaction force of the spring contact pieces used for the electrodes of the batteries becomes large. Therefore, in the above-mentioned conventional lock mechanism, when an impact is given due to a drop or the like, a problem that the lock claw is disengaged has become apparent.
[0004]
FIG. 1 is a perspective view showing an example of a battery lid lock mechanism in a battery housing of a digital camera.
Four AA batteries 4 are stored in a battery storage section 9 of the digital camera body 1. An end of the battery cover 2 is rotatably attached to the digital camera body 1 by a shaft 7. A lock lever 3 having a lock claw 3b at the tip is slidably attached to the battery cover 2.
[0005]
A contact piece (not shown) connected to the electrode of the AA battery 4 is provided on the back side of the battery lid 2, and a coil spring contact piece 6 is arranged on the bottom of the battery housing 9. When the upper surface of the battery cover 2 is pushed, the contact piece on the back side of the battery cover 2 pushes the battery, and when the battery cover 2 is further pushed in, the lock claw 3b of the lock lever 3 is caught by the locking portion 5 protruding from the body and locked. State.
[0006]
FIG. 2 is a cross-sectional view for explaining an operation in which a lock claw of a lock lever is engaged with a locking portion and locked.
When the battery cover 2 is closed as indicated by the imaginary line (two-dot chain line), the inclined back surface 3 e of the lock claw 3 b of the lock lever 3 abuts on the corner 5 b of the locking portion 5. When the lock lever 3 is further pushed in, the lock lever 3 moves rightward against the coil spring 12, so that the tip of the lock claw 3 b descends while hitting the tip of the locking portion 5 and reaches the lower portion of the tip of the locking portion 5. The inner surface 3d of the lock claw 3b is locked to the locking surface 5b of the locking portion 5 by the urging force of the coil spring 12, as shown in FIG.
[0007]
Since the coil spring contact piece 6 and the reaction force of the contact piece on the back surface of the battery cover exert a force to push the battery cover 2 upward, the inner surface of the lock claw 3b is engaged with the locking portion 5 when the lock claw 3b is locked. And the battery cover 2 is locked without rattling. To release the lock, the lock claw 3b is disengaged from the locking portion 5 by opening the battery cover 2 by sliding the release knob 3a rightward against the coil spring 12.
[0008]
FIG. 6 shows a locked state of a conventional lock lever and a locking portion.
When four AA batteries are accommodated and the total reaction force 14 pushed by the battery contact pieces is large, the lock claw 3b and the lock lever 3 warp as shown in FIG. 5a comes into pressure contact with one point on the upper surface of the lock claw 3b.
For this reason, as described above, there is a problem that the battery cover is easily detached due to an impact or the like.
The object of the present invention is to solve the above-mentioned problem. For example, when four AA batteries are used in a digital camera or the like and the reaction force for pushing the battery lid is large, the battery lid is locked by a drop impact or rough handling. An object of the present invention is to provide a lock mechanism for a battery cover that is prevented from coming off.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, a lock mechanism for a battery lid according to the present invention is configured such that a lock lever having a lock claw at a tip end and being provided with a movement habit is slidably attached to a battery lid having one end pivotally connected thereto. When the battery cover is closed, the inclined rear surface of the lock claw hits a locking portion on the body side, and the lock inner surface of the lock claw is locked by sliding the lock lever slightly back against the movement behavior. A battery lid locking mechanism in which the locking inner surface of the locking claw presses and locks the locking surface of the locking portion due to a reaction force of a spring contact piece that is locked to the locking surface of the locking portion and connected to the battery at the same time. The angle of the locking inner surface of the lock claw is inclined by 15 ° ± 10 ° with respect to the locking surface of the locking portion.
[0010]
According to the above configuration, when the inner surface of the lock claw is locked to the locking portion, the inner surface of the locking claw comes into contact with the locking surface of the locking portion by surface contact, and does not easily come off even when an impact is applied.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 3 is a view showing an embodiment of a lock mechanism for a battery cover according to the present invention, showing the shape of a lock lever.
The lock mechanism has the same structure as in FIGS. 1 and 2, and the shape of the lock claw of the lock lever is as shown in FIG.
The angle of the inner surface of the lock lever 8 with respect to the locking surface 5a of the locking portion 5 is set to 15 ° ± 10 °.
[0012]
FIG. 4 shows an engagement state between the lock claw and the locking portion when the shape is as shown in FIG. When a large reaction force of the contact piece of the battery is applied, the lock lever 8 is deformed. As a result, the inner surface 8b of the lock claw 8 and the locking surface 5a of the locking portion 5 come into surface contact.
In such a face contact state, the battery lid does not come off even if, for example, a drop impact is applied.
The inventor of the present invention conducted a drop impact test with the shape shown in FIG. 3 and confirmed that the impact did not cause the battery lid to open.
In the drop impact test, the camera is dropped from a predetermined height, and this is repeated a predetermined number of times. As a result of locking the locking claw, the battery is repeatedly dropped a predetermined number of times in the conventional shape as shown in FIG. Although the lid was sometimes opened, the result was obtained that the lock claw shape of the lock mechanism according to the present invention never opened.
[0013]
FIG. 5 is a perspective view for explaining the relationship between the strap installation position and the lock mechanism. When the stopper 10 is provided at the corner of the digital camera body 1 on the battery housing side and is held by the strap 11, the side of the digital camera body 1 is pulled in the direction of arrow 13 by the weight of the digital camera body 1. Therefore, the locking amount between the locking claw of the locking lever and the locking portion is reduced. It is not preferable to install the strap 11 at such a position with respect to the battery lid locking mechanism. However, if the shape of the lock claw is configured as in the present invention, the position where the strap is provided may be the position shown in FIG. 5, and there is no restriction on the strap mounting position in the camera design.
Although the example of FIGS. 1 and 2 describes the case where there is one lock lever, if one lock lever is insufficient, the same applies even if two or more lock levers are provided.
[0014]
【The invention's effect】
As described above, the present invention provides, for example, AA by setting the inclination of the inner surface of the lock claw of the lock lever to be locked to the locking portion to 15 ° ± 10 ° with respect to the locking surface of the locking portion. When four batteries are stored and the reaction force of the battery contact piece is large, the inner surface of the locking claw is configured to engage with the locking surface of the locking portion by surface contact, so that an impact may be applied to the main body. Even if rough handling is performed, the effect that the battery cover is not easily opened can be obtained.
