COCK DEVICE
Document Type and Number:
Japanese Patent JP3028478
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To recognize the full opening/full closing of an orifice by the touch of the hand in operating a handle by forming an approximately circular arc guide groove in a cylindrical wall tip of a cock handle, by projecting a projection for inserting into the guide groove on the inside wall stage part of a cock base, and by providing narrow and small parts for applying the resistance to the projection.
SOLUTION: A circular arc guide groove 6 is recessedly provided in the tip of a side wall 2 of a cock handle 1 having a handle 4 for rotational operation integrally formed therewith and grooved walls are slightly projected or protruded from the both sides to the front parts in the both sides of the guide groove 6 so as to form narrow and small parts 9, 10. A cylindrical and low projection 31 as a projecting part is projected to the front face of a stage part 25 of the cock base 21 opposite to the guide groove 6 so that, when the cock handle 1 is inserted into the cock base 21, the tip face of the cock handle 1 is brought in contact with the stage part 25 of the cock base 21 and the projection 31 is fitted in the guide groove 6, so that a user feels clicking in the narrow and small parts 9, 10.
