Tilt hinge
First Claim
1. A tilt hinge comprising:
- a bracket for mounting on the side of a body of an equipment and having a bearing section;
a rotating shaft adapted for installing to an end of an opening and closing member rotatably mounted to the bearing section of said bracket;
a cam plate having elasticity, the cam plate provided with at least one recess and an irregular-shaped hole through the cam plate, the cam plate interposed between a large-diameter portion of the rotating shaft and one side face of the bearing section, the rotating shaft inserted through the irregular-shaped hole for rotating the cam plate with the rotating shaft;
a first friction washer interposed between the cam plate and the bearing section and having an insertion hole through which the rotating shaft is inserted, the first friction washer rotating with the cam plate;
a non-rotating section friction washer mounted on the other, second side of the bearing section, the rotating shaft being inserted therethrough and locked to said bracket;
a plurality of disk springs mounted on the rotating shaft in contact with the second friction washer;
a nut connected to one end of the rotating shaft for pressing the plurality of disk springs toward the second side of the bearing section;
a retaining washer having a second irregular-shaped hole therethrough, the retaining washer interposed between the nut and the plurality of disk springs with the rotating shaft inserted through the second irregular-shaped hole, the retaining washer rotatable with the rotating shaft;
a ball mounted on the bearing section of the bracket oriented capable of contacting the at least one recess in the cam plate; and
a plate spring for pressing the ball against the cam plate.

Abstract
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.
