Patent number: 10759451Abstract: A swing body engages with a driving end roller of a linearly moved driving slider at a driving end section. The swing body engages with a guide groove in a driven slider at a driven end section. The driven slider is coupled to a gap filler plate by a driven end roller changeable in installation position in a predetermined direction. A gap filler has an inverse motion preventive structure that, when the gap filler plate is in either a fully protruded state or a fully stored state, enables only forward motion transfer from the driving slider to the swing body. The guide groove is formed in a direction orthogonal or almost orthogonal to forward and backward movement directions of the gap filler plate. The predetermined direction and the direction of the guide groove are parallel to each other in the fully stored state.Type: GrantFiled: September 21, 2018Date of Patent: September 1, 2020Assignee: KYOSAN ELECTRIC MFG. CO., LTD.Inventor: Ikuo Sakurai

Patent number: 10737703Abstract: A first link mechanism section converts linear motion of a driving slider into swing motion of a swing end roller. A second link mechanism section swings in cooperation with the swing end roller on a roller contact surface of a second link lever section, and an output end roller changeable in attachment position presses a driven slider fixed to a gap filler plate. In a fully protruded state and a fully stored state of the gap filler plate, the direction of acting force of the roller contact surface pressing the swing end roller aligns with a straight line connecting the swing end roller and a swing shaft of a first link lever section.Type: GrantFiled: September 21, 2018Date of Patent: August 11, 2020Assignee: KYOSAN ELECTRIC MFG.
