Publication number: 20120098494Abstract: Female guide portions for slidingly attaching a battery pack are formed by integral molding of a case main body. Exposed step portions are formed on the female guide portions, which includes protruding portions as thin-walled portions by application from the outer side (the upper side) of a mold so as to reduce the thickness of a thick-walled resin portion. An opening communicating with the inner and outer side of the case is not provided, while the protruding portions are formed as thin-walled portions. Bottom surfaces of the exposed step portions are formed so as to be sloped with respect to the horizontal direction when the battery charger is placed on a horizontal base, and water dropped on the bottom surfaces can flow outside of the case due to the slope without remaining thereon.Type: ApplicationFiled: October 24, 2011Publication date: April 26, 2012Applicant: MAKITA CORPORATIONInventors: Hironori OGURA, Mamoru SAKAI

Patent number: 8164303Abstract: A charging socket has a base and a holding body covering the base. The holding body has an opening receiving recess, and a first holding plate. A gear element has a ring-like body mounted in the base. The ring-like body has gear teeth at an outer periphery thereof, and a connecting portion connected with the base by a connecting spring for forcing the ring-like body to rotate. A swingable arm pivoted to the base has a ratchet tooth engaged with the gear teeth for stopping the ring-like body from being pulled by the connecting spring to rotate. A movable element has a basic plate slidably received in the receiving recess, and a second holding plate. A side of the basic plate is connected with a rack parallel to a sliding direction of the movable element and is lower than a bottom of the basic plate, engaging with the gear teeth.Type: GrantFiled: November 27, 2009Date of Patent: April 24, 2012Assignee: Cheng Uei Precision Industry Co., Ltd.Inventor: Chu-Keng Lin
