To provide a rotary unit and a rotation support used for television, etc., with a simple structure, which can generate an adequate friction torque and has a strength enough to prevent an escape and fracture during its use, even if it is made of aluminum die-cast material or synthetic resin article, a lower interior cylindrical body and an upper interior cylindrical body are provided on an upper disc portion and a lower disc portion of a fixed cylindrical body and/or a rotary cylindrical body rotatably connected by a hinge shaft, and a reinforcing member is attached to the lower and the upper interior cylindrical bodies. The reinforcing member comprises an insertion hole in which the hinge shaft is inserted, wherein locking portions provided on a plurality of locking pieces (which are provided by folding the outer circumference portions) are locked by the lower and the upper interior cylindrical bodies.

Rotary unit apparatus and rotation supporting apparatus

In order to reduce a number of parts and required costs, and to improve operability during assembly and maintenance, the automatic original cover closer comprises hinge portions having a supporting member which supports the original cover to be opened and closed with regard to a main body of an office equipment and a driving portion automatically driving the supporting member of the hinge portions. The automatic original cover closer is characterized in that the supporting member is rotatably supported via a rotation shaft on a mounting member attached to the main body, that the driving portion comprises a driving motor and a driving force transmitting mechanism for transmitting a rotation drive force of the driving motor to the rotation shaft, and that the rotation shaft is adjusted so that its rotation drive force can be transmitted to the supporting member via a shaft engaging members fixedly attached thereto.

Automatic original cover closer and office equipment having the same

An automatic original cover closer to practically realize an automatic opening and closing function of an original cover, has a hinge part to rotatably support an original cover to the main body of office equipment and a driving part to automatically drive the hinge part. The hinge part includes a mounting member to mount on the main body and a supporting member to support the original cover to be axially supported to this mounting member so as to be rotatable with a rotary shaft via the rotary shaft. The driving part includes a positively and reversely rotatable drive motor and a power transferring mechanism to decelerate and transfer the rotary driving power of this drive motor to a drive shaft. The rotary driving power of the drive motor is transferred to the supporting member via the drive shaft and the rotary shaft, by connecting the rotary shaft to the drive shaft.

Automatic original cover closer and office equipment including automatic original cover closer

A tilting hinge is provided which includes a first bracket consisting of a fixing plate portion and a bearing plate portion bent at a right angle relative to the fixing plate portion, the fixing plate portion being fixed to any one of the body of an apparatus and a component part of the apparatus, installed pivotably to the latter and the bearing plate portion having a non-circular bearing hole formed therein; a cylinder having a fixing portion formed at one end and a friction torque generating hole formed axially in it, the fixing end portion being inserted and fixed in the non-circular bearing hole in the bearing plate portion of the first bracket; a second bracket consisting of a fixing plate portion and a bearing plate portion bent at a right angle relative to the fixing plate portion, the fixing plate portion being fixed to the other of the body and component part of the apparatus and the bearing plate portion having formed in it a non-circular bearing hole; and a radially elastic spring pin having provided at one end a fixing end portion inserted and fixed in the non-circular bearing hole in the bearing plate portion of the second bracket; the spring pin being press-fitted at the free end into the friction torque generating hole in the cylinder to be rotatable with a friction with the outer surface of the cylinder and the wall surface of the friction torque generating hole.

Tilting hinge

An operative hinge for use with an opening/closing body is provided which comprises a hinge case to be installed to a toilet bowl body for operating the opening/closing body; a shaft provided rotatably within the hinge case to support the opening/closing body; a stationary cam fixed within the hinge case and having formed therein a central through-hole through which the rotating shaft is axially penetrated; a cam provided within the hinge case and having formed therein a central through-hole through which the rotating shaft is axially penetrated to be slidable on, and rotatable with, the rotating shaft; and a resilient means for urging the rotatable sliding cam toward the stationary can, the hinge further comprising, to further positively control the rotation or the rotating means, a damping means consisting of a rubber ring fitted on the rotating shaft and interposed between the outer surface of the rotating shaft and the inner wall of the hinge case; and a viscous oil applied between the outer surface of the rubber ring and inner wall of the hinge case; the rubber ring having spiral recesses formed on the outer surface thereof.

Operative hinge for opening/closing body

A semi-automatic toilet bowl seat and seat lid operator, comprising a hinge case to be installed to a toilet bowl body; a rotating shaft to support a seat and seat lid of the toilet bowl openably and closably; an output gear mounted on the rotating shaft; a fluid damper having a damper gear in mesh with the output gear; a reduction gear coupled to the output gear by means of a torque limiter; a motor coupled to the reduction gear; and a drive circuit to drive the motor in a range from an opened angle, to a predetermined closed angle, of the seat and seat lid. The drive circuit is provided with a sensor to detect an operation made to open the seat and seat lid, and a timer which is turned on by the sensor to turn on the drive circuit in a predetermined time after the sensor is turned on. The seat and seat lid of the toilet bowl can be opened and closed by hand, and the opened seat and seat lid can be automatically closed slowly with the semi-automatic operator.

Semi-automatic closing device for seat lid of toilet bowl

An operating hinge for a seat and seat lid of a toilet bowl, simply constructed and capable of controlling the angular moment of the seat and lid to softly stop them in place at their respective predetermined ends of pivoting stroke, provided. The operating hinge comprises a hinge case to be installed to a body of a toilet bowl, a shaft provided rotatably within the hinge case, a stationary cam secured inside the hinge case and having formed therein a central hole through which the rotating shaft is axially penetrated, a cam provided inside the hinge case in a vis-a-vis relationship with the stationary cam and having formed therein a central hole through which the rotating shaft is axially penetrated, to be slidable on, and rotatable with, the rotating shaft, and a resilient member for urging the rotatable sliding cam toward the stationary cam; further comprising, to more positively control the rotation of the rotating shaft, a rubber ring fitted on the rotating shaft to abut the inner wall of the hinge case, and a viscous oil applied between the periphery of the rubber ring and the hinge case inner wall the rubber ring abuts.
