Patent number: 5991936Abstract: A Western style toilet seat and seat cover opening-closing device is disclosed, in which a rotating shaft is rotatably mounted in the axial direction of a case body designed to be mounted on the toilet bowl, and a first rotation control of the rotating shaft is provided in a part housed in the case body. In the case body above or below the first rotation control a second rotation control of the rotating shaft are vertically juxtaposed. Between the second rotation controls and the first rotation control mechanism, a driving power transmitting mechanism is disposed. On the rotating shaft, one of the seat or seat cover mounting sections is rotatably mounted through a bearing, while the other is so fixed as to rotate together with the rotating shaft.Type: GrantFiled: January 20, 1998Date of Patent: November 30, 1999Assignee: Katoh Electrical Machinery Co., Ltd.Inventor: Akira Sorimachi

Patent number: 5974595Abstract: A device for automatically closing an open toilet seat after an adjustable low-speed phase to permit the user to finish using the toilet. The seat then closes at a speed which is adjustable by the user separately from the initial low speed. A biasing member is used to urge the open seat toward the closed position. A pneumatic or hydraulic dampener is mechanically linked to the seat and slows the seat's descent. As the seat rotates toward the closed position it causes a reciprocating member to move inside the dampener. As the reciprocating member moves it forces a dampening fluid to flow from the main chamber of the dampener, through one or both of two openings, to a low pressure area within the dampener. During the low-speed phase, the reciprocating member blocks and prevents the flow of the dampening fluid through one of the openings. This heavily restricted flow allows the seat to move very slowly at first.Type: GrantFiled: October 20, 1998Date of Patent: November 2, 1999Inventor: Robert J. McCabe

Patent number: 5918322Abstract: A toilet seat 40 and a toilet lid 50 are pivotably attached to an attachment base 20 of a western-style toilet bowl 10 with a hinge mechanism 30. The hinge mechanism 30 includes first and second rotational resistance mechanisms 60R and 60L which are respectively mounted on opposing sides of the attachment base 20. First right and left hinge parts 42R and 42L are respectively integrally formed at opposite ends of the toilet seat 40. Second right and left hinge parts 52R and 52L are respectively integrally formed at opposite end part of the toilet lid 50, the first and second support pins 36R and 36L and the caps 38R and 38L. The first rotational resistance mechanism 60R applies rotational resistant force in the lowering of the toilet seat 40 via the first support pin 36R. The second rotational resistance mechanism 60L applies rotational resistant force in the lowering of the toilet lid 50 via the second support pin 36L.Type: GrantFiled: July 22, 1997Date of Patent: July 6, 1999Assignee: Toto Ltd.Inventors: Hirofumi Yamamoto, Toshihiro Fukuda

Patent number: 5901383Abstract: The slide support base 62 protrudes from the supporting wall 56 of the support recess 52 in the casing main body 14 and the tube-shaped support part 122 on the side of the toilet lid 100 is supported by and capable of sliding over its cylindrical surface 65a. The rotational pin 70 of the viscous resistance mechanism 80 protrudes from slide support base 62 and the rotational pin 70 fits in the fitting recess 132 on the side of the toilet lid 100. That is, the toilet lid 100 is pivotably supported to the casing main body 14 by two support structures. To remove the toilet lid 100 from the casing main body 14, the toilet lid is raised to the upright position and then applied with upward force to be pulled out. Since the opening 124 and the opening 136 are formed in the tube-shaped support part 122 and the fitting recess 132, the toilet lid 100 is removed from the casing main body through them.Type: GrantFiled: September 19, 1996Date of Patent: May 11, 1999Assignees: Toto Ltd., Koito Industries, Ltd.Inventors: Yasuhiro Yanagawa, Tetsuo Nishimoto, Hiroshi Matsuo, Akio Fujii, Akihiko Nakajima, Takao Sakama

Patent number: 5898953Abstract: A Rising Seat that can be fixed permanently to a seat or toilet and which can also be readily adapted as a portable seat. It comprises a top rising section on which the user sits, pivoted to a bottom section. There is at least one torsion spring located on a torsion bar that may also act as a hinge. When the legs of any selected number of springs are placed in spaces/openings incorporated in the seat, those springs become inoperable having been moved away from firm surfaces on the rising seat against which they give resilience to the top section. This enables adjustment to be made to suit the weight of the user, and when the legs of all the springs are placed in the spaces/openings the top section can be folded down without resilience for carriage and storage and to give the appearance of a standard seat cushion when not in use.Type: GrantFiled: November 22, 1997Date of Patent: May 4, 1999Inventor: John B.
