Patent number: 11949803Abstract: The present invention provides a locking mechanism in a mobile terminal and a method of manufacturing the same. The locking mechanism comprises a slider, latch, button, and spring. The slider and latch include openings and may translate between a locked position and an unlocked position. The latch may include a protrusion that limits the translation of the slider and the latch when in the locked position. The button is located within the opening of the slider and the opening of the latch, and the spring member is fixed adjacent the latch. In an instance in which an external force is applied to the button, the external force deforms the spring member such that contact between a vertical edge of the protrusion and the spring is precluded allowing translation of the slider and the latch between the locked position and the unlocked position.Type: GrantFiled: January 20, 2023Date of Patent: April 2, 2024Assignee: Hand Held Products, Inc.Inventors: Xianwei Yan, Zach Zhang, Xiaofang Yang, David Chaney
