Patent number: 6674183Abstract: A contact 24 is fitted to an insulator complete 25, and the contact 24 is adapted to rotate in correspondence with the operation of an operation knob. The length of an arm 38 among arm portions 37 to 39 which are provided on the contact 24 is set to be shorter than the other arm portions 37 and 39. As a result, fixed contacts 40a and 41a with which movable contacts 37a and 38a provided at distal ends of the arms 37 and 38 are brought into contact can be arranged at concentric positions, thereby making it possible to increase the number of contacts. In this case, since a relay for a small-current load is connected to the fixed contact 41a, no hindrance is caused even if the contact force of the second movable contact 38a is set to be small by devising the angles between the respective ones of the arm portions 37 to 39.Type: GrantFiled: July 26, 2000Date of Patent: January 6, 2004Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Masuo Noda, Kazuyoshi Ishiguro

Patent number: 6223610Abstract: When a leaf spring 22 is rotated integrally with the rotation of a knob dial 18, the leaf spring 22 is pushed and deflected by three corners of a cylindrical section 17a. After that, when three corners of the cylindrical section 17a get over the leaf spring 22 and new three surfaces are engaged with the leaf spring 22, rotation of the knob dial 18 is regulated. In this case, the pushing direction of the leaf spring 22 is the same as the direction of deflection. Therefore, the rotational resistance of the knob dial 18 can be reduced. Accordingly, a feeling of operation of the knob dial 18 becomes light.Type: GrantFiled: April 14, 1999Date of Patent: May 1, 2001Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Kazuyoshi Ishiguro, Mitsuru Naka

Patent number: 6176589Abstract: When a knob dial 18 is turned on, a predetermined LED 15c to 15e corresponding to a rotational position of the knob dial 18 is turned on. Then, a beam of light is supplied to a predetermined indicator lens 29a to 29f via a predetermined light path 30, and the indicator lens 29a to 29f can be illuminated. In this structure, the optical path 30 is formed into a sector-shape. Therefore, even if the knob dial 18 is set at an intermediate position, the beam of light emitted from LED 15c to 15e is supplied to the indicator lens 29a to 29f via the optical path 30. Accordingly, the indicator lens 29a to 29f can be illuminated to the utmost.Type: GrantFiled: April 14, 1999Date of Patent: January 23, 2001Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventor: Kazuyoshi Ishiguro

Patent number: 6034340Abstract: Upon depression of a depression surface of an operating knob of a switch assembly, a depression working surface pushes down the head portion of a rubber contact, and a switching operation is performed. The operating knob is pushed up by the return elastic force of the rubber contact and returned to its original position. Then the upper face of the depression portion abuts against the correction member. As the correction member is positioned directly above the rubber contact, the moment generated by the return elastic force of the rubber contact is offset and the operating knob is straightened and maintained to be in a horizontal position. Therefore, the side surfaces of the head portion projecting from the operation hole of the switch case barely rub against the side edges of the operation hole in a depressed state owing to inclination of the operating knob.Type: GrantFiled: April 8, 1999Date of Patent: March 7, 2000Assignee: Kabushiki Kaisha Tokai-Rika-Denki-SeisakushoInventors: Yoshiyuki Aoki, Kazuyoshi Ishiguro

Patent number: 5777282Abstract: Contact holders accommodated in defined regions are elastically returned to initial positions on the side of a wall. At the initial positions, stoppers are formed integral with a wall which defines the regions, in such a manner that the stoppers are in parallel with the wall and spaced a distance from the wall. Those stoppers are each in the form of a thin plate, and have protrusions which are extended towards the contact holders, respectively. Hence, when returning to the initial positions, the contact holders and strike against the protrusions of the stoppers, so that the latter are bent towards the wall while reducing the distance, thus decreasing the impact thereon when the contact holders strike against the stoppers.Type: GrantFiled: October 9, 1996Date of Patent: July 7, 1998Assignees: Kabushiki Kaisha Tokai Rika Denki Seisakusho, Denso CorporationInventors: Kazuyoshi Ishiguro, Masuo Noda, Hiroshi Kataoka, Shinji Iwama
