Patent number: 7887031Abstract: A stay damper comprises a cylinder (1) in which a gas is charged, a piston rod (2) which projects under a pressure of the gas in the cylinder (1), and a stopper (10) which locks contraction of the piston rod (2) in an elongated position. The stopper (10) displaces between a lock position which locks contraction of the piston rod (2) and a release position which permits contraction of the piston rod (2) according to directional operation forces applied by an operator. The stopper (10) comprises a restricting member (12, 13) which holds the stopper (10) in the lock position when it is in the lock position and holds the stopper (10) in the release position when it is in the release position. Since the locking operation of the stopper (10) is performed manually, the releasing operation thereof is easily understood by the operator.Type: GrantFiled: August 28, 2006Date of Patent: February 15, 2011Assignee: Kayaba Industry Co., Ltd.Inventors: Hiroshi Murota, Takashi Asa, Yasushi Saitou

Publication number: 20100201052Abstract: A gas spring is intended to permanently maintain the sealing performance of a lip in a dust seal without being affected by pressure from a gas sealed inside the spring. A rod body is operates in conjunction with a cylinder body with a gas of a predetermined pressure sealed inside the cylinder body. The rod body is movable into and out of the cylinder body. A rod guide is penetrated by the rod body at a shaft core portion inside a head end portion of the cylinder body. A dust seal has with a lip in sliding contact with an outer circumference of the rod body. A sealed end portion of the cylinder body is in contact with an outer end of the rod guide inside the cylinder body. The dust seal is integrally incorporated at the outer end portion of the rod guide.Type: ApplicationFiled: April 7, 2010Publication date: August 12, 2010Applicants: Toyota Jidosha Kabushiki Kaisha, Kayaba Industry Co., Ltd., Yanagisawa Seiki MFG., Co., Ltd.Inventors: Takumi Katayama, Katsuya Iwamoto, Takashi Asa, Yasushi Saitou
