Patent number: 11175579Abstract: A reticle pod includes a body, cover, sliding-rail member, sliding-fastening member and shut-corresponding element. The sliding-rail member has a dent portion and a slot portion and defines a locked direction. The dent portion extends from the slot portion in the locked direction. The sliding-fastening member is slidably disposed at the sliding-rail member. The sliding-fastening member has a fastening portion and resilient arms. The resilient arms are inserted into a slot of the slot portion. The fastening portion has a fastening groove corresponding in height to the slot portion. An oblique-guide surface is disposed above the fastening groove. When the cover switches from an open state to a closed state, the shut-corresponding element pushes the sliding-fastening member across the oblique-guide surface and thus compresses the sliding-fastening member, allowing the shut-corresponding element to enter the fastening groove.Type: GrantFiled: May 18, 2020Date of Patent: November 16, 2021Assignee: GUDENG PRECISION INDUSTRIAL CO., LTD.Inventors: Chia-Ho Chuang, Hsin-Min Hsueh, Yu-Chen Chu, Ming-Chien Chiu

Patent number: 9541956Abstract: A supporting structure and a docking station using the same are provided. The supporting structure includes an elastic member, a sliding member, a lifting element and a damper. The sliding member having an inclined plane is connected to the elastic member. When the elastic member receives a force, the elastic member forces the sliding member to move along an axis line with the inclined plane facing to the lifting element. The lifting element is arranged over a travel path of the inclined plane and has an abutting portion. When the lifting element receives another force so that the abutting portion abuts against the inclined plane, the sliding member stops moving and the height position of the lifting element is fixed. The damper is mated with the sliding member to slow down the velocity of the sliding member.Type: GrantFiled: November 12, 2014Date of Patent: January 10, 2017Assignees: UNIVERSAL SCIENTIFIC INDUSTRIAL (SHANGHAI) CO., LTD., UNIVERSAL GLOBAL SCIENTIFIC INDUSTRIAL CO., LTD.Inventors: Ming-Jen Chen, Kuo-Kuang Liu, Yu-Chen Chu, Chang-Cheng Lin

Publication number: 20080019036Abstract: A positioning device includes two guiding members fixed spacedly in a housing. Each guiding member has a hook-shaped guiding slot having an elongate first slot portion, and a curved second slot portion defined by front and rear stop walls. A pivot member is connected pivotally to a detachable module. Two positioning rods of the pivot member are respectively guided by the first slot portions of the guiding slots in the guiding members to move rearwardly as a result of rearward movement of the detachable module until the positioning rods abut respectively against the rear stop walls. The pivot member is then pivoted to move the positioning rods to abut respectively against the front stop walls, thereby resulting in further rearward movement of the detachable module by a predetermined distance in response to continuous pivoting of the pivot member.Type: ApplicationFiled: March 2, 2007Publication date: January 24, 2008Inventors: Yu-Chen CHU, Kuo-Kuang LIU
