In order to provide a closing device for a covering member, which is smaller than a conventional device, can stably hold the covering member at a predetermined open angle, and is manufactured at low cost, the closing device comprises: a rotary shaft having a flange part and a means to be fixed to the covering member side; a guide plate which is rotatably retained by a side facing the flange part of the rotary shaft and has means to be fixed to the device body; a first click plate fixed to the guide plate so as to be rotatable around the rotary shaft together with the guide plate; a second click plate which is in contact with the first click plate and is attached to the rotary shaft so as to be non-rotatable and slidable in the axial direction; and a compression means compressedly arranged between the second click plate and the flange part in order to press toward the first click plate side.

Closing device for covering member

To provide a tilt hinge capable of obtaining a great frictional torque despite of its small size and insuring a clip stop, the present invention comprises a bracket to be mounted on the body side of the equipment, a rotating shaft designed to be mounted to the end of an opening-closing body which is rotatably mounted on a bearing section of the bracket, a friction washer mounted between the large-diameter portion of the rotating shaft and the bearing section and/or on the other side face of the bearing section with the rotating shaft inserted into the central part, and an elastic means mounted with the rotating shaft inserted in the central part to press the friction washer against the large-diameter portion and/or the bearing section; and a click stop means is provided between the rotating shaft and the bracket. In this case, the elastic means may be a plurality of disk springs or spring washers; and the click stop means may be comprised of a cam plate rotating together with the rotating shaft, a ball provided on the bracket side, in contact with the cam plate, and an elastic means to press the ball against the cam plate side, or may be comprised of a cam plate having elasticity and rotating with the rotating shaft, and provided with a single or a plurality of recesses, small holes or cutouts, and a ball fixed on the bracket side, in contact with the cam plate, and intermittently entering the recess, small hole or cutout.

Tilt hinge

An operating device of an opening-closing body is supported on both sides on a single rotating shaft and controls the turning torque of the rotating shaft. To realize the operating device, a rotating shaft having a flange portion on one side is rotatably mounted by inserting in a pair of bearing holes coaxially formed in a pair of bearing members which are erected as parallel walls at a predetermined spacing; the rotating shaft being provided with opening-closing body mounting portions on both ends which protrude out of the pair of bearing members; a friction washer is interposed between the flange portion and the bearing member and rotates together with the rotating shaft; a stationary cam member is secured on one of the bearing members, with the rotating shaft rotatably inserted through at the central part; a rotating-sliding cam member is disposed oppositely to the stationary cam member and capable of sliding in the axial direction of the rotating shaft while turning together with the rotating shaft; and furthermore a compression spring is inserted over the rotating shaft to press the rotating-sliding cam member towards the stationary cam member side to thereby press the friction washer between the flange portion and the bearing member. The compression spring can adjust a pressure to be applied to the rotating-sliding cam member and a pressure to be applied to the friction washer.

Operating device of opening-closing body

A tilt hinge comprises a fixing member composed of a fixing base fixed to a main body of a device and a bearing plate; a rotating shaft having a small diameter part rotatably born at the bearing plate of this fixing member; a first friction washer placed between a large diameter part of the rotating shaft and one side surface of the bearing plate with its small diameter part being inserted into and passed through its central part; a second friction washer arranged to be contacted with the other side surface of the bearing plate with the small diameter part being inserted through its central part; a pressing plain washer arranged to be contacted with this second friction washer with the small diameter part being inserted into and passed through its central part; wherein the end part of the small diameter part is press fitted to cause the first friction washer to be press contacted between the bearing plate and the large diameter part and the second friction washer to be press contacted between the bearing plate and the spring washer.

Tilt hinge for office automation equipment

A first rotating shaft supporting an opening-closing body and rotating with the opening and closing operation of the opening-closing body is rotatably mounted on a mounting member attached on an apparatus body side. A first friction mechanism works on the rotating shaft. A main driving gear is mounted on the first rotating shaft so as to rotate together with the first rotating shaft. A second rotating shaft is mounted on the mounting member; on the second rotating shaft a driven gear engaged with the main driving gear is mounted to rotate with the second rotating shaft. Also, on the second rotating shaft a second friction mechanism works. Furthermore, a click stop means works on the first rotating shaft.
