Patent number: 10289165Abstract: An electronic device having two chassis stably attached to each other is provided. The electronic device includes a first chassis having a display and a second chassis detachable from the first chassis. The second chassis includes a support post that protrudes from the attachment surface to which the first chassis is attached and has a claw portion on a tip side. The first chassis includes a post hole into which the support post is inserted and an engaging projection that engages with the claw portion of the support post inserted into the post hole and elastically biased so that the claw portion can be pressed towards the insertion direction to the post hole. The first chassis has an engaging slider having the engaging projection where the engaging projection is elastically biased in a direction of engaging with the claw portion.Type: GrantFiled: August 3, 2018Date of Patent: May 14, 2019Assignee: LENOVO (SINGAPORE) PTE LTDInventors: Tabito Miyamoto, Masayuki Amano
