Patent number: 7585183Abstract: Switches for a variety of circuits for different purposes are formed by using a plurality of similarly designed contact modules each having a module case incorporating a normally closed or normally open contact mechanism and a plunger for operating this contact mechanism, a single actuator having two end parts and being biased so as to rotate around a supporting axis between these contact modules, this actuator undergoing a rotary motion if a force is applied to one of its end parts so as to operate the plunger of an associated one of the contact modules with at least one of the end parts, a switch case that contains the contact modules and the actuator, and a push button for applying a force on one of the end parts of the actuator from outside the switch case.Type: GrantFiled: August 10, 2007Date of Patent: September 8, 2009Assignee: OMRON CorporationInventors: Kenji Shimazu, Shunkichi Sasaki, Hidemitsu Takenaka, Tetsuya Fukumoto

Patent number: 7504597Abstract: A key switch has a switch part and an operating part. The switch part is activated to switch contact points as an operating key is inserted. The operating part includes a driver cam that rotates as it is pushed by the operating key and to activate the switch part and a plurality of lock cams configured to directly lock the driver cam in a normal condition when the operating key is pulled out of the operating part and to rotate as it is pushed by the operating key so as to release the driver cam from its locked condition. The key switch may further include lock cam holder for holding the lock cams in the normal condition when the operating key is pulled out.Type: GrantFiled: February 20, 2007Date of Patent: March 17, 2009Assignee: OMRON CorporationInventors: Kenji Shimazu, Shunkichi Sasaki, Hidemitsu Takenaka, Tetsuya Fukumoto, Shinya Yamamoto, Shinya Watanabe

Patent number: 7456368Abstract: In order to perform maintenance of a working robot, a worker pulls a handle of a slider and moves the slider backward to thereby withdraw a slider fitting portion from a fitting hole portion and withdraw an actuator from an operating portion of a door switch. In this case, a key inserted into a key hole of a lock is rotated through 90° to vertically orient an interference protruding portion to thereby prevent fitting of the slider fitting portion into the fitting hole portion. Only in this state, the key can be withdrawn from the key hole of the lock.Type: GrantFiled: February 21, 2007Date of Patent: November 25, 2008Assignee: Omron CorporationInventors: Tetsuya Fukumoto, Yoichi Shude, Shigeki Nakanishi, Shunkichi Sasaki, Hidemitsu Takenaka, Kenji Shimazu

Patent number: 6720508Abstract: A switch includes a switching mechanism, an operating mechanism with a key which normally causes the switching mechanism to be in a switched-off condition when it is pulled out and to be displaced against a biasing force to be in a switched-on condition when the key is inserted, and a locking mechanism for maintaining the switching mechanism locked in the switched-on condition and releasing it from the locked condition if a load greater than a specified magnitude is applied to the key while the switching mechanism is locked such that the switching mechanism is set back in the switched-off condition. The switching mechanism may be contained in a head case attached to a main case containing the operating mechanism. The main case also includes a forcing mechanism which tends to force the switching mechanism in the switched-off condition.Type: GrantFiled: June 17, 2002Date of Patent: April 13, 2004Assignee: Omron CorporationInventors: Hiroyuki Moriyama, Shingo Akiyama, Takashi Niwa, Sueaki Honda, Minoru Yoshii, Hiroyuki Kajio, Hidemitsu Takenaka, Kazuki Kawata, Tetsuhiko Miyoshi

Patent number: 6664487Abstract: A limit switch has switch areas and a partition wall in between in a switch case for containing switch element units separately and independently. An inner case includes covers for sealing the switch areas. For improving rigidity, a switch unit and a head unit which operates the switch unit are connected by means of a protrusion on one of them and an indentation on the other of them, the protrusion and the indentation being engaged in an embracing fashion for strength.Type: GrantFiled: June 24, 2002Date of Patent: December 16, 2003Assignee: Omron CorporationInventors: Hidemitsu Takenaka, Hiroyuki Kaijo, Tetsuhiko Miyoshi

Patent number: 6459052Abstract: A door switch disclosed includes a switch body and a key unit which are attached to a structure and a door, respectively. The switch body is provided with a door key insertion hole and a switch contact. The key unit has a door key and a door key drive mechanism in its unit case. The door key drive mechanism retreats the door key into the unit case when the door is opened and protrudes it out from the unit case when the door is closed, to thereby insert the door key into the door key insertion hole in the switch body, thus turning ON the switch contact.Type: GrantFiled: May 9, 2001Date of Patent: October 1, 2002Assignee: Omron CorporationInventors: Hiroyuki Kajio, Takashi Niwa, Hidemitsu Takenaka, Yasuo Isa
