Patent ID: 8322248

Claim:
An adjusting screw assembly for a control lever device for a vehicle, said lever device having a threaded hole therein and said adjusting screw assembly comprising: a threaded shank which is screwed into said threaded hole, an actuating head affixed to a first end of the shank for unitary rotation therewith, a funnel shaped seat formed at a second end of the shank opposite the actuating head, wherein both the actuating head and the funnel shaped seat have a diameter which is greater than a diameter of the threaded shank, at least one depression on a contact surface of the actuating head facing the threaded shank, said shank having an annular seat adjacent said actuating head, and a locking body mounted on the shank, said locking body comprising an annular locking plate seated in said annular seat on said shank, said annular seat preventing the annular locking plate from moving along the shank, the annular locking plate having at least one projection which engages the depression in the actuating head so as to prevent unintended rotation of the actuating head with respect to the locking body, the plate being elastically deformable so that application of sufficient torque to the actuating head disengages the projection from the depression and allows the actuating head to turn with respect to the locking body, and an anchoring tab extending from the annular locking plate for abutting the lever device so as to prevent the locking body from rotating with respect to the threaded hole wherein the actuating head is removably connected to the first end of the shank and the first end of the shank has a front surface from which an elongated connecting portion protrudes for connecting the shank to the actuating head, such that said contact surface of the actuating head faces said front surface, wherein the front surface works together with a part of the elongated portion and with the contact surface to form said annular seat to house the locking body in a manner that the engagement of the projection of the locking plate with the depression on the contact surface remains constant.
