Definitions

  • the present invention relates to a joint structure for a watch and a watch adopting the structure, and more particularly to a joint structure for fastening a joint pin to the joint portion for a watch.
  • Figs. 12 and 13 show an example of a conventional joint method used in a watch.
  • a long pin 34 and a short pipe 35 are used as joint members. More specifically, when a joint portion 30 of a watch case and a joint portion 32 of a band are coupled with each other, first of all, a hollow pipe 35 is inserted into an insertion hole 31 of the joint portion 30 of the case in advance. Then, the joint portion 32 of the band is lifted and insertion holes 33 and 33 of the joint portion 32 of the band are in alignment with the insertion hole 31 of the joint portion 30 of the case. Then, a pin 34 is pressed into three holes 33, 31 and 33 and thus the case and the band of the watch are connected to each other.
  • a small annular recess 36 is formed in the middle of the pin 34 so that the pin 34 is prevented from falling away from the pipe 35 during use of the watch.
  • the recess 36 of the pin 34 fits into a small annular recess 37 in the middle of the pipe 35 so that the pin 34 is fixed.
  • Fig. 14 is a view showing the structure of another conventional joint structure of a watch shown in Japanese Patent Application Laid-Open No. Hei 08-224114.
  • Pin insertion holes 41 and 41 into which an insertion pin 50, having stepped portions 53 and 53 at both ends, is inserted are formed in bifurcated joint portions 42 and 42 of a watch case 40.
  • a through hole 46 having a cocoon-shaped cross-section is provided in a joint portion 45 of the band.
  • a spacer 47 having the same cross-sectional shape is inserted into the through hole 46.
  • a ring 60 having a cocoon-shaped cross-section with a large diameter hollow portion 61 and a small diameter hollow portion 62 divided at a waist portion 63 of the central portion of the cross-section is inserted into hollow portions 48 and 49 of the spacer 47.
  • the large diameter hollow portion 61 of the ring 60 has an inner diameter such that large diameter portions 52 and 52 of the insertion pin 50 may be inserted loosely into the ring 60.
  • the small diameter hollow portion 62 has an inner diameter that is substantially the same as a diameter of a small diameter portion 51 of the insertion pin 50.
  • the waist portion 63 is formed so that it has a narrower width than the inner diameter of the small diameter portion 62.
  • the fixing force of the pipe 35 is weakened in order for the pin 34 not to be bent (that is, the inner diameter of the small outer diameter 37 of the pipe 35 is increased), a risk that the pin 34 would be fallen away in case of use of the watch becomes remarkable.
  • the fixing force thereof is increased, the work is very difficult when the pin 34 is to be fallen away in order to release the joint.
  • the small outer diameter portion 37 of the pipe 35 is plastically deformed. The depression of the pin 34 having a larger outer diameter than the inner diameter of the small outer diameter portion 37 of the pipe 35 is rather difficult. In addition, in this case, the force for depressing the pin is likely to be varied.
  • a manufacturing method for the through hole 46 having the cocoon-shaped cross-section needs rather complicated steps, resulting in the increase of the cost.
  • there is another method for the formation of the through hole 46 in which after the joint portion 45 of the band 5 is divided into upper and lower parts (see the dotted line in Fig. 14) and half holes for the through hole 46 are formed, both halves are bonded together.
  • the number of the mechanical parts is increased and the number of the manufacturing steps is increased, resulting in the degradation in productivity and the increase of the entire cost for the watch.
  • the present invention has been made in order to overcome the above-noted problems, and has an object to provide a joint structure for a watch and a watch using the joint structure in which the number of mechanical parts is decreased, the manufacture and assembly are simple and costs therefor are low, furthermore, the attachment/detachment is easy, and there is no fear that a joint pin would be fallen away in case of use of the watch.
  • a joint structure for a watch in which a case joint portion for joint provided on a case for the watch and a band joint portion for joint provided on a band are laterally disposed adjacent to each other, engagement holes in communication with each other in a lateral direction are provided in both the joint portions, respectively, and a joint pin for coupling the case for the watch and the band with each other is inserted into each of the engagement holes,
  • the joint structure being characterized in that a coiled spring is inserted into at least either one of both the engagement holes, and the joint pin is inserted into an inner diameter of the coiled spring so that the joint pin is retained by the inner diameter portion of this coiled spring and applied to both the engagement holes.
  • each coil wraps the outer surface of the outer diameter of the pin so that the total frictional force is increased and there is no fear that the pin would be accidentally fallen away.
  • the fixing force for the pin is the frictional force or the retaining force caused by the resiliency of the coiled spring, upon the attachment/detachment work, it is possible to easily perform the work without using a special tool or a large force. There is no fear that the watch would be damaged or the pin would be bent.
  • another joint structure for a watch including a joint structure for a band to be connected to a watch body in which at least two joint members are connected, comprising an engaging joint portion for joint provided on one of the joint members and an engaged joint portion for joint provided in a lateral direction adjacent to the engaging joint portion for the one joint member to be disposed in a connection direction adjacent to the other of the joint members, wherein engagement holes in communication with each other in a lateral direction are provided in both joint portions, a coiled spring is inserted into at least either one of both the engagement holes, and a joint pin is inserted into an inner diameter of this coiled spring so that the joint pin is retained by the inner diameter portion of this coiled spring and applied to both the engagement holes.
  • the weight of the overall band may be reduced. Since the attachment/detachment work of the joint portions may be simple, the work efficiency is enhanced and at the same time the band may be finished with an aesthetic design. Furthermore, since the coiled spring is used, the number of the manufacture steps is decreased to reduce the cost. Since the joint pin is retained by utilizing the inner diameter portion of the coiled spring, the resiliency of the coiled spring may be utilized effectively, it is easy to couple the components with each other, and in addition, it is possible to realize a function to make it possible to remove the joint pin without any strong force but the joint is not easily released.
  • either one of the two joint portions is bifurcated projections
  • any other of the two joint portions is a projection to be inserted into the bifurcated projections
  • the engagement hole is formed as a through hole in each of the bifurcated projection and the projection
  • the coiled spring is inserted into the engagement holes of the projections
  • the joint pin is disposed so as to be applied to the three through holes.
  • the coiled spring is inserted in the middle of the projections, it is possible to positively prevent the coiled spring from being fallen away. Also, since the three through holes have a diameter that is somewhat greater than that of the pin and the joint portions may be thinned, it is possible to enhance the aesthetic design.
  • an inner diameter of a part of the coiled spring is formed into a small diameter spring portion that is smaller in diameter than the other portion
  • an outer diameter of a part of the joint pin is formed into a small outer diameter portion that is smaller in diameter than the other portion
  • the small diameter spring portion is fitted around the small outer diameter portion to thereby retain the joint pin.
  • the small diameter spring portion of the coiled spring is fitted with the small outer diameter portion of the joint pin to thereby retain the joint pin.
  • Such a structure further enhances the force for fixture of the pin. Also, when the pin is pulled out, the pull-out is easy due to the resiliency of the spring and there is almost no fear that the force for removal would be varied. Also, since it is unnecessary to use a special tool, the cost will not be increased and there is no fear that the joint portions would be damaged.
  • an inner diameter of the coiled spring is somewhat smaller than an outer diameter of the joint pin, and the joint pin is retained between the coiled spring and the joint pin by contact friction.
  • the inner diameter of the coiled spring is somewhat smaller than the outer diameter of the pin.
  • a watch comprising a watch body having a watch case where a case joint portion for joint is provided and a band having a band joint portion disposed adjacent to the case joint portion, wherein engagement holes for communication of the two joint portions in a side surface direction are provided in the two joint portions, respectively, a joint pin are passed through the engagement holes to thereby couple the watch case and the band, wherein a coiled spring is inserted into at least either one of both the engagement holes, and the joint pin is inserted into an inner diameter of the coiled spring so that the joint pin is retained by the inner diameter portion of the coiled spring and applied to both the engagement holes.
  • the joint work may readily be attained.
  • the coiled spring may be machined with ease so that the number of the manufacture steps is decreased and the cost therefor may be reduced.
  • the joint pin is retained by utilizing the inner diameter portion of the coiled spring, the resiliency of the coiled spring may be utilized effectively, it is easy to couple the components with each other, and in addition, it is possible to realize a function to make it possible to remove the joint pin without any strong force but the joint is not easily released.
