摘要： A storing and recharging base for a cordless electric vacuum cleaner of the type which includes an elongated housing having an electric motor and fan and rechargeable batteries therein. The base has a flat bottom and key slots so that it can rest on a horizontal flat surface or be hung on a wall. The base has an upper surface contoured generally complementary to the lower surface of the vacuum cleaner housing, and has a pocket at one end which receives a nose portion of the vacuum cleaner, and a spring at the other end which releasably engages in a recess in the vacuum cleaner so that the vacuum cleaner can be stored on a horizontal surface, e.g. on a counter top or shelf, or in a drawer, or can conveniently be hung on a wall. The base also has a plug which electrically engages a receptacle in the vacuum cleaner connected to the batteries. A line cord connects the plug to a charger plug which includes a transformer and a plug for insertion into an A.C. outlet so that the batteries can be continuously recharged when the vacuum cleaner is stored on the base. The base is formed with wireways in which the line cord can be wrapped to vary the length of the line cord extending from the base.
摘要翻译：一种用于无绳电动吸尘器的储存和充电基座，其包括具有电动机和风扇的细长壳体以及其中的可再充电电池。底座有一个平底和钥匙槽，使其可以放在一个水平的平面上或挂在墙上。底座具有与真空吸尘器外壳的下表面大致互补的上表面轮廓，并且在一端具有容纳真空吸尘器的鼻部的口袋，在另一端具有可释放地接合在凹部中的弹簧真空吸尘器，使得真空吸尘器可以存储在水平表面上，例如在柜台或货架上，或在抽屉里，或者可以方便地挂在墙上。底座还具有插塞，该插头与连接到电池的吸尘器中的插座电接合。电源线将插头连接到充电器插头，充电器插头包括变压器和插头插入交流电源插座，以便当真空吸尘器存放在底座上时，电池可以连续充电。底座形成有导线，其中线绳可以被包裹以改变从底座延伸的线绳的长度。

摘要： A battery retention latch (350) comprises a retaining member (354), a release button (356) and a cam element (362). A biasing member 358 maintains the retention catch in a normally engaged position. The cam element (362) retains a battery pack (26) in a cordless device (352) regardless of the annular orientation of the battery pack (26) about a casing axis. A holding device (382, 394) maintains the battery (26) in the cavity (34) against a spring ejecting force such that the battery (26) partially extends from the device (352) enabling the battery (26) to be removed from the device (352).
摘要翻译：电池保持闩锁（350）包括保持构件（354），释放按钮（356）和凸轮元件（362）。偏置构件358将保持夹持件保持在正常接合位置。凸轮元件（362）将电池组（26）保持在无绳装置（352）中，而不管电池组（26）围绕套管轴线的环形取向如何。保持装置（382,394）抵抗弹簧弹出力将电池（26）保持在空腔（34）中，使得电池（26）从装置（352）部分地延伸，使得电池（26）能够从设备（352）。

摘要： An enclosure 12 for a disposable battery pack 10 for a cordless power tool consists of a pair of end caps 26, 28 retained on the opposite ends of the pack by a central sleeve 30 of adhesive tape. The end caps are of unitary construction, formed from thin plastic sheet, and include raised terminal covers 32, 34, 36 for shielding exposed terminals 20, 22, 24 from inadvertent outside contact. Each terminal cover has a severable tip 50 which is removed when the pack is to be used, to provide an opening 56 for insertion of a terminal connector 60.

摘要： A power tool has a mechanism to reverse a motor. The mechanism includes a first member secured with the motor surrounding the motor commutator. A pair of electrical contacts are supported in the first member. A second member is rotatable on the fist member. The second member carries a pair of brush holders which include electrical contacts. As the second member is rotated in the first member, the electrical contacts of the brush holders, as well as the electrical contacts in the first member, electrically couple with one another from a first position to a second position which relates to a forward and reverse direction of the motor. A lever moves the second member between its first and second positions.
