Definitions

  • FIG. 1 is a cross sectional view showing a construction of a conventional rotating bezel section.
  • FIG. 2 is a plan view showing a conventional rotating bezel section where a spring is set in.
  • F IG. 3 is a cross sectional view showing a rotating bezel section before assembling according to the present invention.
  • FIG. 4 is a cross sectional view showing a rotating bezel section after assembling according to the present invention.
  • the present invention relates to a construction of a rotatable ring (hereinafter referred to a rotating bezel) attached to the periphery of a watch case.
  • FIG. 1 and 2 is a construction of a conventional rotating bezel section.
  • 1 is a rotating bezel, 2 a case band of a watch and 3 a spring by which the rotating bezel l is fixed rotatably to the case band 2 and having a bending portion 11 and a straight portion 10 as shown in FIG. 2.
  • 6 is formed in the inner surface of the rotating bezel 1. It is a groove for receiving the spring 3. 4 is the outer wall of the groove, 9 a lower wall of it. Further 7 is formed in the case band. It is also a groove for receiving the spring 3. is the inner wall of the groove. 8 an upper wall of it.
  • the spring 3 has been useful for controlling the rotating force and also preventing the rotating bezel from disengaging. Therefore, the shape and the dimension of the bending portion 11 and the straight portion 10 of the spring 3 have had a-subtle influence on the rotating force and disengagemerit of the rotating bezel 1. In other words, the spring of high accuracy was required to control the rotating force and'to prevent disengagement. However, a spring itself has an elasticity and it is difficult to make it with high accuracy. Thus, the productivity couldt be increased. Moreover, the spring 3 formed with the bending portion 11 and the straight portion 10 is apt to deform permanently after setting in once. So if the spring deformed was set in again, the rotating force was changed and the rotating bezel was apt to disengage. Therefore, when re-setting in the spring, amendment was required in bending.
  • a rotating bezel has been used mainly for a waterproof watch case. When such a watch was put into the water, water was apt to come in the gap in the rotating bezel section. Besides it was difficult to wipe away water from the outside. Therefore, rust was apt to produce on the spring 3 or the groove 6 of the rotating bezel l and the groove 7 of the case band 2 etc. Further the rotating bezel was sometimes unable to rotate itself.
  • the spring 3, the case band 2 and the rotating bezel 1 are all made of metals. Namely a metal contacts with a metal each other. So when the rotating bezel 1 is rotated, uncomfortable feeling is transmitted to the tips of fingers. Such watches are not desirable as marketable products. In order to eliminate this uncomforatable feeling, in some watches such springs have been only used to prevent the bezel from disengaging. Thus other parts such as a packing was used together.
  • the object of the present invention is to eliminate above defects and to provide an improved construction of a rotating bezel section.
  • 12 is a rotating bezel, 13 a packing made of synthetic resins or rubbers etc. and having an elasticity, 16 a case band of a watch case, 15 a groove which is formed in the inner surface of the rotating bezel in order to receive the packing 13.
  • 20 is the outer wall of the groove 15 and 18 the lower wall of it.
  • 14 is a groove which is formed in the case band 16 in order to receive the packing 13.
  • 17 is the upper wall of the groove 14 and 19 the inner wall of it.
  • packings may have 0 shape or D shape in the cross section. They can perform same function above.
  • a gutter for oil may be provided in order to make the rotation smooth.
  • both functions such as the control of the rotation of the rotating bezel and the prevention from disengagement are carried out by setting the packing 13 having uniform elasticity in the space formed by the grooves 14 and 15 which are formed on the case band 16 and the rotating bezel 12 respectively.
  • a difficult process such as spring bendingetc. is not required.
  • all the parts can be easily adapted to the related dimensions. Further. the productivity can be promoted and the watches of high quality can be obtained.
  • the contact between the packing 13 made of rubbers or synthetic resins and the rotating bezel or the case band 16 made of metals make the rotation of the rotating bezel very smooth. Therefore, the watches of high quality as marketable products can be provided.
  • the packing 13 has an elasticity itself, re-assembly can be easily carried out without conventional subtle adjustment. Besides as a packing is received in the grooves, water doesnt get in and the grooves 14 and 15 are prevented from rusting. Then as a packing itself resists rust, it can be completely prevented that the rotation doesnt carry out due to the rust on a groove or a packing etc.
  • a watch case providing for rotation of a bezel comprising a caseband having an outer wall with an annular groove, a bezel having an inner wall surrounding said outer wall of said caseband, said inner wall having an annular groove therein located at a position complementary to that of said groove in said outer wall and an annular packing received in said grooves, the inner wall of said bezel having a free end sloped to facilitate introduction of said packing into said bezel during assembly of said watch case, the depth of said groove in said caseband being greater than the depth of said groove in said bezel so that said packing may be retained in said groove in said caseband during any later removal of said bezel from said caseband, and the total depth of both grooves relative to said annular packing being such that accidental disengagement of said bezel from said caseband is prevented while permitting of said grooves has a gutter therein for reception of a lubricant smooth rotation of said bezel around said caseband and space to tat tati n fSaid bezel.
