Description
【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、時計の巻真切換部構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a winding stem switching portion structure of a timepiece.
この考案は、地板と一体に突設して設けた樹脂製のピン
でおしどりの回動中心を支持するおしどりピンを形成
し、かつ地板をおしどりの回動中心部の外形部と遊嵌す
るように形成した時計の構造を開示するものである。In this invention, a resin pin provided so as to project integrally with the main plate is used to form a male pin that supports the pivot center of the ratchet, and the main plate is loosely fitted to the outer shape of the pivot center of the ratchet. The structure of the timepiece formed in the above is disclosed.
従来は第４図に示すように、おしどり３の回動中心を支
持するおしどりピン１は、金属で形成され樹脂で形成さ
れた地板２に打設結合する構造がとられていた。Conventionally, as shown in FIG. 4, the lever pin 1 that supports the center of rotation of the lever 3 has a structure in which it is driven and coupled to a base plate 2 made of metal and made of resin.

いう課題を有していた。However, the conventional structure in which the male pin 1 formed of metal is driven and coupled to the main plate 2 formed of resin, unintentional impact force or force may be applied to the external operation member 4 from the outside due to the fall of the watch body. When operated, the external pin 4 is attached to the posterior pin 1.
Since a force is applied via the torso 3 and the impact force is absorbed at the driving joint between the posterior pin 1 and the ground plate 2, the bonding strength between the posterior pin 1 and the ground plate 2 is reduced, and the external operating member 4
When operating the watch body via the, the normal operation could be impaired. Further, when the external operating member 4 receives an impact, the posterior pin 1 may fall off and the operating function of the timepiece may be lost. Further, the back pin 1 and the base plate 2 on which the back pin 1 is driven are driven with a fitting allowance in order to obtain a coupling force, so that a crack may occur in the base plate 2 main body, and There were times when the bond strength could not be obtained. Further, also in the production of the main plate 2, there is a problem that the step of placing the temple pins 1 is added and the steps are complicated.
前記問題点を解決するために本考案は、地板２に打設さ
れるおしどりピン１を廃止し、地板２と一体にピン２ａ

持つように形成させたものである。In order to solve the above-mentioned problems, the present invention eliminates the male pins 1 mounted on the main plate 2 and integrates the pins 2a with the main plate 2.
Is formed so as to have a loose fit with the outer shape of the rotation center of the lever 3.

る。In the structure configured as described above, when the posterity 3 is rotated by the external operation member 4, the posterior pivot center pin 2a of the main plate 2 and the posterior guide wall 2b provide stable rotation, and When an impact force or the like is applied to the operating member 4 from the outside, the impact force received by the lever 3 is loosely fitted along the outer shape of the swing rotation center pin 2a of the main plate 2 and the rotation center portion of the swing 3. Since the impact guide force is absorbed by the formed posterior guide wall 2b, a stable center of rotation of the posterior 3 can be obtained. Compared to the case where impact force is placed on the main plate 2, the stable operation function of the timepiece can be maintained even after impact, and in the manufacturing process, the step of placing the pin 2 on the main plate 2 is performed. Since it can be omitted, it is possible to simplify the manufacturing process and prevent the occurrence of cracks in the main body 2 of the main plate due to the act of placing.

計体の外部操作機能を提供できる。An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, a rotation center pin 2a for supporting the rotation center of the temple 3 rotated by the external operation member 4.
Are formed so as to integrally project with the base plate 2 made of resin. The outer shape portion 3a of the rotation center portion of the temple 3 whose rotation center is supported by the rotation center pin 2a is formed in a circular shape from the rotation center of the temple 3, and the circular shape portion 3a of the temple 3 and The guide guide portion 2b of the base plate 2 is formed by loose fitting. The center of rotation of the posterity 3 is guided by the posterior pivoting center pin 2a of the main plate 2 and the posterior guide portion 2b to provide a stable center of rotation. The external impact force acting on the external operation member 4 is caused by the rotation center hole of the temple 3 and the outer shape portion 3a of the center of rotation contacting the temple rotation center pin 2a and the temple guide portion 2b of the main plate 2, respectively. It is possible to provide a stable external operation function of the watch body that is dispersed and absorbed and is stable even after the external impact force is applied.

とができる。As described above, the present invention can eliminate the conventional setting of the setting pin and can provide a stable external operation function even after the external impact force is applied. Further, since the driving pin is eliminated, the manufacturing process can be simplified. Further, it is possible to provide a stable operation function without the occurrence of cracks in the main plate body and reduce the number of parts of the timepiece.
