Definitions

  • the fixing of the dial is ordinarily ensured by the construction wherein the point of the dial screw or the conical part of flush screw head in the tapped hole drilled in the side of the plate locks the dial foot.
  • This invention is directed to the remedy of these di advantages.
  • An object of this invention is the provision of a dial pin which can fix the dial easier and surer by using an eccentric pin instead of screw.
  • FIG. 1 is a plan view of embodiment of this invention.
  • FIG. 2 is a sectional view, taken along the line A-A' of FIG. 1.
  • 1 denotes the dial pin, comprising a thin cylindric portion 1a, a truncated conical collar portion 1b to engage at the dial foot 4 and a head portion 1c provided with a slot.
  • the dial 3 is provided with dial foot 4.
  • the thin cylindric portion 1a and the collar portion 1b are eccentric and the center of rotation of the dial pin 1 is that of the thin cylindric portion 1.
  • the thin cylindric portion 1a of said dial pin 1 tightly fits within an aperture in the plate 2, said tight fit permitting the rotation of said dial pin 1.
  • the fitting of the cylindric portion 1a within the aperture in the plate scarcely changes after rotation of said dial pin, due to the elastic effect of the cylindric portion 1a which forms a thin cylinder having center hole 1d.
  • the fitting of the said dial on the plate is easily achieved. Further, the loosening of the dial, the loosening of the dial pin and falling out of the said pin will not occur. Moreover, as there is no necessity for thread cutting, said pin can be manufactured at low cost.
  • a dial pin for a watch having a plate formed with a pair of spaced first and second apertures therein and a dial having a foot extending through a first of said apertures, said dial pin comprising a cylindric portion formed with a bore therethrough defining a tubular cross section dimensioned for snug receipt within said second plate aperture; and a head portion having a collar portion projecting radially outwardly from said cylindric portion and eccentrically disposed relative to said cylindric portion, said collar portion being tapered inwardly from the side thereof adjacent said cylindric portion, said collar portion being dimensioned so that one peripheral region thereof is engageable against said dial foot when said cylindric portion and said dial foot are positioned respectively in said first and second plate apertures and another peripheral portion thereof is not so engageable when said cylindric portion and dial foot are so positioned.
