Patent number: 9263715Abstract: A battery pack includes a casing having an opening, an engaging member having a stopper, and a regulating member configured to regulate a movement of the engaging member. The engaging member is supported in a slidable and rotatable manner relative to the casing, and is applied with a biasing force such that the stopper projects from the opening. The regulating member includes a contact portion configured to block a rotation of the engaging member and an operating portion configured to displace the contact portion to release a blocking of the rotation of the engaging member. When the operating portion is a non-operated state, the engaging member is slidable against the biasing force to retract the stopper. When the operating portion is in an operated state, the engaging member is rotatable against the biasing force to retract the stopper.Type: GrantFiled: April 10, 2012Date of Patent: February 16, 2016Assignee: MAX CO., LTD.Inventors: Terufumi Hamano, Akira Teranishi, Hajime Takemura, Keisuke Koitabashi

Patent number: 9263716Abstract: A battery holder for use with a battery-powered sensor may be configured such that removing the battery involves at least two distinct motions. The battery holder may include a cradle and a resilient retention strap configured to be deflectable between relaxed and deflected positions. With the retention strap in the relaxed position, the cradle and the retention strap may cooperate to retain the battery in the inserted position within the battery holder. The battery may be removed by first manipulating the retention strap from the relaxed position to the deflected position, and then using a distinct second motion to remove the battery from the holder. The battery holder may be configured to substantially prevent movement of the battery relative to the cradle when the battery is in the inserted position. The battery holder may be configured to facilitate insertion of the battery into the holder in a desired orientation.Type: GrantFiled: February 21, 2013Date of Patent: February 16, 2016Assignee: LUTRON ELECTRONICS CO., INC.Inventors: Brandon L.
