特開平２００８−２３６８８１号公報Japanese Patent Laid-Open No. 2008-236881

しかしながら、電池パックを充電する場合、電池パックだけを持って充電器に抜き差しすることは通常できず、充電器を手で押えて電池パックの抜き差しを行っている。携帯用工具等の電池パックは比較的小さくて軽い物であるが、電動芝刈り機等の電池パックはそれよりも大きくて重くなる傾向にあり、しかも充電器よりも重い場合が多い。このような大きくて重い電池パックを充電器に抜き差しする場合はかなり力を要することとなり、従来の充電器のように充電器のハウジングを手で押えて電池パックを抜き差しするのでは非常に操作性がよくないという問題があった。   However, when charging a battery pack, it is not usually possible to hold the battery pack alone and insert / remove it into / from the charger, and the battery pack is inserted / removed by holding the charger by hand. Battery packs such as portable tools are relatively small and light, but battery packs such as electric lawn mowers tend to be larger and heavier and are often heavier than chargers. When inserting and removing such a large and heavy battery pack in and out of the charger, it takes considerable power, and it is very easy to operate by inserting and removing the battery pack by holding the charger housing by hand like a conventional charger. There was a problem that was not good.

本発明は、上記問題を解決するためになされたもので、簡単な構成で電池パックを充電器から操作性良く抜き差しすることが可能となる充電器を提供することを目的とする。   The present invention has been made to solve the above-described problem, and an object of the present invention is to provide a charger that can easily insert and remove a battery pack from the charger with a simple configuration.

上記目的を達成するために、充電器に電池パックを抜き差しするときに充電器のハウジングを手でつかむ握り部を設けた構成とする。また、握り部は、充電器において電池パックを抜き差しする方向線上であって、電池パックを充電器から抜く方向の反対側の充電器のハウジングに設けた構成とする。さらに、握り部はハンドル状であって、その開口の大きさが把持用ハンドルの開口よりも小さいこと、または、握り部とハウジングの間に凹みを有していることを特徴としている。   In order to achieve the above object, a grip portion for holding the charger housing by hand when the battery pack is inserted into and removed from the charger is provided. In addition, the grip portion is provided on the charger housing on the opposite side of the direction in which the battery pack is removed from the charger on the direction line in which the battery pack is inserted and removed from the charger. Further, the grip portion has a handle shape, and the size of the opening is smaller than the opening of the grip handle, or a recess is provided between the grip portion and the housing.

本発明によれば、握り部を設けたので、電池パックの抜き差し時に充電器のハウジングを容易につかんで固定することができ、便利である。また、本発明によれば、電池パックを充電器から抜く方向の反対側の充電器のハウジングに握り部を設けたので、抜き差し時に力が入りやすく操作性の良い抜き差しが可能となる。さらに、本発明によれば、握り部はハンドル状であって、その開口の大きさが把持用ハンドルの開口よりも小さいので、握り部を把持して充電器を運搬することがなく、充電器に装着している電池パックが運搬時に不用意に落下するということがないという効果を奏する。握り部とハウジングの間に凹みを有している場合も同様の効果がある。   According to the present invention, since the grip portion is provided, the housing of the charger can be easily grasped and fixed when the battery pack is inserted and removed, which is convenient. In addition, according to the present invention, since the grip portion is provided on the housing of the charger opposite to the direction in which the battery pack is removed from the charger, it is easy to apply force during insertion / removal, and insertion / extraction with good operability is possible. Furthermore, according to the present invention, the grip portion has a handle shape, and the size of the opening is smaller than the opening of the grip handle, so that the charger is not carried by gripping the grip portion. There is an effect that the battery pack attached to the battery pack does not fall inadvertently during transportation. The same effect can be obtained when there is a recess between the grip portion and the housing.

以下に、本発明を添付図面に示す実施形態に基づいて説明する。図１において、１は本発明にかかる充電器で、２は充電される電池パック、３は本発明にかかる充電器の握り部、４は充電器の把持用ハンドルである。図２は図１の平面図と側面図であり、矢印Ａは電池パック２を充電器１から抜き去る方向を示している。   Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. In FIG. 1, 1 is a charger according to the present invention, 2 is a battery pack to be charged, 3 is a grip portion of the charger according to the present invention, and 4 is a handle for gripping the charger. FIG. 2 is a plan view and a side view of FIG. 1, and an arrow A indicates a direction in which the battery pack 2 is removed from the charger 1.

図３は充電器１の平面図と側面図であり、充電器１は、上部ハウジング５ａと下部ハウジング５ｂで形成される箱状のハウジング５内に図示しない充電回路を収めてなるものである。ハウジング５の一方には充電器１を持ち運ぶのに便利なように把持用ハンドル４が形成されている。また、ハウジング５の他方であって把持用ハンドル４の反対側には、充電器１に電池パック２を抜き差しするとき、充電器１を手でつかんで固定しやすいようにハンドル状の握り部３が形成されている。図示しない充電回路からの充電電流や充電時の制御用信号は電池パック取付ホルダー６に形成された端子６ａを通して電池パックの図示しない接続端子に接続されるように構成されている。６ｂは電池パック２を充電器１の電池パック取付ホルダー６に留めるためのフックである。   FIG. 3 is a plan view and a side view of the charger 1, and the charger 1 includes a charging circuit (not shown) housed in a box-shaped housing 5 formed by an upper housing 5a and a lower housing 5b. A grip handle 4 is formed on one side of the housing 5 so as to be convenient for carrying the charger 1. Further, on the other side of the housing 5 on the opposite side of the grip handle 4, when the battery pack 2 is inserted into and removed from the charger 1, a handle-like grip portion 3 is provided so that the charger 1 can be easily held and fixed. Is formed. A charging current from a charging circuit (not shown) and a control signal at the time of charging are configured to be connected to a connection terminal (not shown) of the battery pack through a terminal 6 a formed in the battery pack mounting holder 6. Reference numeral 6 b denotes a hook for fastening the battery pack 2 to the battery pack mounting holder 6 of the charger 1.

ハウジング５と把持用ハンドル４との間には把持用開口部４ａがあり、把持用開口部４ａは充電器２を運搬する者がそこに手を入れて把持用ハンドル４を握るための開口であり、貫通した穴として形成されている。同様に、握り部３を握りやすくするためには握り部３とハウジング５の間に開口を設けるのがよく、握り開口部３ａとして図３に表示されている。しかし、握り開口部３ａは把持用開口部４ａのように必ずしも貫通した穴である必要性はない。充電器１を運搬する者が誤って握り部３を握って運搬すると充電器１に電池パック２が装着されている場合は電池パック２が下向きになり装着が不十分であると落下する恐れがある。そのような誤操作をしないように握り開口部３ａは貫通していない凹みであってもよい。同様な理由から握り開口部３ａの開口の大きさは、把持用開口部４ａの開口の大きさより小さいのが望ましい。   Between the housing 5 and the grip handle 4, there is a grip opening 4a. The grip opening 4a is an opening through which a person carrying the charger 2 puts his hand to grip the grip handle 4. Yes, it is formed as a through hole. Similarly, in order to make the grip portion 3 easy to grip, an opening may be provided between the grip portion 3 and the housing 5, which is shown in FIG. 3 as a grip opening portion 3a. However, the grip opening 3a does not necessarily have to be a through hole unlike the grip opening 4a. If the person who carries the charger 1 accidentally grasps and holds the grip portion 3 and carries the battery pack 2, when the battery pack 2 is attached to the charger 1, the battery pack 2 may face downward and may fall if the attachment is insufficient. is there. The grip opening 3a may be a dent not penetrating so as not to cause such an erroneous operation. For the same reason, the size of the opening of the grip opening 3a is preferably smaller than the size of the opening of the grip opening 4a.

次に、本発明の充電器の操作について説明する。電動芝刈り機等の操作者が電池パック２を充電しようとするときは、電池パック２の図示しない接続端子を充電器１の電池パック取付ホルダー６に差し込み、そこに形成された端子６ａと接続することが必要である。この接続を完全なものにするために操作者は、たとえば左手で充電器１の握り部３を握り、右手に持った電池パック２を矢印Ａの反対方向に向けて差し込むようにする。差し込みが完全であると電池パック取付ホルダー６のフック６ｂが電池パック２をしっかり留めるように働く。図１および図２はこのようにして電池パック２を充電器１に装着した状態を表している。   Next, the operation of the charger of the present invention will be described. When an operator such as an electric lawn mower tries to charge the battery pack 2, a connection terminal (not shown) of the battery pack 2 is inserted into the battery pack mounting holder 6 of the charger 1 and connected to the terminal 6 a formed there. It is necessary to. In order to complete this connection, for example, the operator holds the grip portion 3 of the charger 1 with the left hand and inserts the battery pack 2 held in the right hand in the direction opposite to the arrow A. When the insertion is complete, the hook 6b of the battery pack mounting holder 6 works to securely fasten the battery pack 2. 1 and 2 show a state in which the battery pack 2 is attached to the charger 1 in this way.

端子間の接続が完了し、図示しない充電スタートスイッチを操作者が操作すると充電が開始される。そして充電が完了すると充電完了ランプ７が点灯し充電完了を操作者に知らせる。   When the connection between the terminals is completed and the operator operates a charge start switch (not shown), charging is started. When the charging is completed, the charging completion lamp 7 is turned on to inform the operator of the completion of charging.

充電が完了した電池パック２を充電器１から取り外すときは、電池パック取付ホルダー６のフック６ｂを外して、たとえば右手で電池パック２をつかみ、左手で充電器１の握り部３を握って電池パック２を矢印Ａの方向へ引っ張るようにすればよく、握り部３をつかむことができるので重い電池パック２であっても容易に充電器１から取り外すことができる。   When removing the fully charged battery pack 2 from the charger 1, remove the hook 6b of the battery pack mounting holder 6, hold the battery pack 2 with the right hand, for example, and hold the grip portion 3 of the charger 1 with the left hand. The pack 2 may be pulled in the direction of arrow A, and the grip portion 3 can be grasped, so that even the heavy battery pack 2 can be easily removed from the charger 1.

本発明に係る充電器は、上述した実施の形態に限定されず、特許請求の範囲で記載した範囲で種々の変形や改良が可能であり、電動芝刈り機以外の機器の電池パックを充電する充電器にも適用可能である。   The charger according to the present invention is not limited to the above-described embodiment, and various modifications and improvements can be made within the scope described in the claims, and the battery pack of equipment other than the electric lawn mower is charged. It can also be applied to a charger.
