Abstract: A damper for a flapdoor that does not show any damping effect when its movable shaft of the damper is rotated with the door in one sense whereas it effectively damps the rotary movement of the flapdoor when the movable shaft is rotated with the door in the other sense, wherein a one-way clutch for engaging or disengaging the movable shaft with a movable member depending on the sense of rotation of the movable shaft to cause a viscous shearing drag in the viscous fluid contained in the damper and a power source constitute so many integral parts of a coil spring. A damper for a flapdoor having such an arrangement can have a simplified configuration as compared with a damper provided with a separate coil spring as power source and a separate one-way clutch and therefore can be realized with reduced dimensions. Moreover, since such a one-way clutch can be prepared from a coil spring without requiring any additional processes and by simply engaging a portion of the coil spring with the movable member, the rest of the coil spring functioning as power source, the damper can be realized at a significantly reduced cost.

Abstract: A toilet covering hinge assembly for mounting a toilet covering to the rear of a toilet for rotation of the toilet covering about a hinge axis between a lowered and a raised position. The hinge assembly includes a hinge element which is provided at the rear end of the toilet covering and is formed with a bore extending along the hinge axis. A hinge shaft extends through the bore in a rotatively fixed relation thereto so as to be rotatable together with the toilet covering about the hinge axis. One end of the hinge shaft is received by a support member provided on the side of the toilet for allowing the hinge shaft to rotate together with the toilet covering relative to the toilet. A retainer spring is secured to the hinge element adjacent to the bore for latching the hinge shaft against an axial movement thereof. The retainer spring comprises an outer section and an inner section having an inner edge projecting radially inwardly into the bore and capable of being resiliently deformed into and out of locking engagement with a stepped shoulder in the outer surface of the hinge shaft.

Abstract: A door closer wherein a housing defines a fluid-containing space for a reciprocable damping piston which divides the space into a first and a second compartment. The piston carries a check valve which is closed during movement of the piston in a first direction while the door panel is being opened and which is open when the piston moves in the opposite direction. A channel is provided in the housing to permit fluid to flow from the first compartment into the second compartment during a first stage of movement of the piston in the first direction. The check valve has a body which defines a passage for the flow of fluid between the compartments and is surrounded by a seat having one or more grooves which are only partially overlapped by a spherical or non-spherical valving element during movement of the piston in the first direction to thus establish a relatively small path for the flow of fluid between the compartments, at least during a second stage of movement of the piston in the first direction, such second stage following the first stage. Springs in that compartment from which fluid is expelled during movement of the piston in the first direction oppose such movement of the piston, and an additional spring can be provided to bias the valving element against its seat.

Abstract: An oil type damper comprises a housing formed of a basic member in the shape of a blind tube and a cap, a rotating member and a braking disc adapted to rotate jointly and accommodated within the housing, viscous oil applied to the braking disc, and at least one flexible membrane opposed to the braking disc so as to allow the braking disc to be sealed in the housing as covered with the oil. In this oil damper, when the oil serving to brake the rotary motion of the rotating member connected to a given door expands in volume because of rising temperature, the flexible membrane is deformed under the pressure of the expanded oil enough to absorb the voluminal expansion of the oil and prevent otherwise possible leakage of the oil from the housing.

Abstract: A rotation damper comprises a base member, a gear wheel rotatably mounted on the base member via a damper, a spiral spring having one end attached to a cap member and the other end attached to the gear wheel and adapted to be wound up with the rotation of the gear wheel, and a locking member for locking the spiral spring in or releasing it from the wound-up state. When the gear wheel is rotated to the neighborhood of a limit position against the spring force of the spiral spring, the spiral spring is locked in the wound-up state. The spiral spring is released from the wound-up state by further rotating the gear wheel. The rotation damper is applicable to a cassette holder of a cassette tape recorder, for instance, and permits the holder to be opened and closed under braking force while eliminating the need for a separate holder locking mechanism.

Abstract: A rotary damper device comprises a base plate, a rotary cylinder rotatably disposed on the base plate through the medium of a damper, and a coil spring interconnecting the base plate and the rotary cylinder. The base plate and the rotary cylinder are interconnected to the main body of a device and the lid of the device.
