Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、表示車付アナログ時計の表示車の構造に関
する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to the structure of a display wheel of an analog timepiece with a display wheel.
従来、アナログ時計の表示車は、第３図に示すように
アルミニウム板等の金属薄板より成る表示板１−ｂを金
属材より成る表示歯車１−ａに固定する際、カシメによ
る方法がとられていた。あるいは、第４図に示すよう
に、アルミニウム板等の金属薄板より成る表示板１−ｂ
をプラスチック樹脂材より成る表示歯車１−ａにアウト
サート成形する事で固定を行っていた。Conventionally, as shown in FIG. 3, a display wheel of an analog timepiece is caulked when fixing a display plate 1-b made of a thin metal plate such as an aluminum plate to a display gear 1-a made of a metal material. Was there. Alternatively, as shown in FIG. 4, a display plate 1-b made of a thin metal plate such as an aluminum plate.
Was fixed to the display gear 1-a made of a plastic resin material by outsert molding.
しかし、前述の従来技術によれば、 表示板を、表示歯車にカシメ固定する際、表示歯車
の中央部をカシメるため、表示板の中央部に歪みが発生
し、表示板にソリ、変形等が生ずる。その結果として文
字板、地板等他の部材とのスレによる運転止まり等の品
質問題が発生すると供に、表示車自身の歩留りの低下、
表示板の印刷外観の悪化等が誘引される。However, according to the above-mentioned conventional technique, when the display plate is caulked and fixed to the display gear, the central part of the display gear is caulked, so that the central part of the display plate is distorted, and the display plate is warped or deformed. Occurs. As a result, when there is a quality problem such as driving stop due to scratches with other members such as dial and ground plate, the yield of the display vehicle itself decreases,
This may lead to deterioration of the printed appearance of the display board.
表示板に用いられている最も一般的な金属薄板とし
てアルミニウム板があげられるが、外観及び強度上の問
題から、アルマイト処理等の表面処理が必要となり、表
示車のコストアップ要因となる。The most common metal thin plate used for the display plate is an aluminum plate. However, because of problems in appearance and strength, surface treatment such as alumite treatment is required, which increases the cost of the display vehicle.
カシメの際、表示板に傷、打痕等を残し易く、歩留
りが低下する。When caulking, it is easy to leave scratches, dents, etc. on the display plate, and the yield is reduced.
アウトサート成形による表示歯車と表示板との固定
の場合、アウトサート成形時の成形温度により表示板が
熱変形したり、プラスチック樹脂と金属材の熱膨張率の
違いにより、金属材より成る表示板の中央部に歪みが生
じ、ソリ、変形等を生ずる。When the display gear and the display plate are fixed by outsert molding, the display plate is thermally deformed due to the molding temperature during outsert molding or the display plate made of a metal material due to the difference in the coefficient of thermal expansion between the plastic resin and the metal material. Distortion occurs in the central part of the, and warp, deformation, etc. occur.

Therefore, the present invention is intended to solve such a problem, and an object thereof is to provide a belt-shaped saray groove in a gear for adhesively fixing a display plate, and to provide a tooth portion of the gear and the display plate. By providing a space between them, it is possible to provide a structure of a display wheel of an analog timepiece which is low in cost and excellent in reliability.
本考案のアナログ時計の表示車の構造は、歯車と、絵

とする。The structure of the display wheel of the analog timepiece of the present invention is the structure of the display wheel of the analog timepiece which is composed of a gear and a display plate for displaying a picture, a month, a day, etc. It is characterized in that a band-shaped saray groove is provided at a contact portion with the display plate, and a gap is provided between a tooth portion of the gear and the display plate.
以下に、本考案の実施例を図面に基づいて説明する。 An embodiment of the present invention will be described below with reference to the drawings.

月、日、曜等の暦表示に加えて、絵柄等の表示がある。FIG. 1 shows a sectional view of a display wheel and its peripheral portion in the present embodiment, and FIG. 2 shows a detailed view of a central portion of the display wheel.
In FIGS. 1 and 2, reference numeral 1 denotes a display wheel, which includes a display gear 1-a and a display plate 1-b. Further, the display gear has two belt-shaped saray grooves 1-c and 1-d and a display plate guide 1
-E. The center wheel of the display wheel is guided by the hour wheel 2 with play, and the display wheel retainer 3 prevents the display wheel from coming off. The power of the indicator wheel is continuously transmitted by the hour wheel and the intermediate wheel 4, and the speed is adjusted by the gear ratio of the intermediate wheel pinion 4-a and the intermediate wheel gear 4-b which form the intermediate wheel. Since the display plate that constitutes the display wheel is made of synthetic paper, it deforms and warps, and even if it slips on the dial 5 or the intermediate wheel, due to the softness of the synthetic paper, there is a serious defect such as stopping driving without applying a load. It does not cause. On the contrary, even if the display vehicle is warped to some extent, it can be used without any problem as long as it is within the allowable range in appearance. In FIG. 2, reference numeral 6 denotes an adhesive for fixing the display gear 1-a and the display plate 1-b. The strip-shaped saray groove 1-c provided on the inner side of the display gear serves as a reservoir for the adhesive. The outflow of the drug is suppressed. Further, even if a part of the adhesive flows out, by providing the band-shaped saray groove 1-d on the outside of the display gear, a space is created between the tooth portion 1-f and the display plate 1-b, and the action of the surface tension of the adhesive itself is exerted. The adhesive prevents the adhesive from reaching the teeth through the bottom of the tooth. In addition, as an example of display on the display board,
In addition to the calendar display such as month, day, and day, there is a display such as a picture.

避できる。As described above, according to the present invention, since the band-shaped saray groove is provided in the contact portion of the gear with the display plate, the excess adhesive when the gear and the display plate are bonded and fixed Since it is absorbed by the saray groove, it is possible to avoid the protrusion to the surroundings.

する。In addition, since a gap is provided between the tooth portion of the gear and the display plate, for example, even when an adhesive that cannot be absorbed by the band-shaped saray groove is used, the adhesive that sticks out is contained in the adhesive itself. By the action of the surface tension, it stays on the outer wall of the gear that forms the void, which prevents the adhesive from flowing out to the teeth. Since the driving of the vehicle can be ensured, there is an effect that it is possible to provide a structure of a display vehicle of an analog timepiece which is low in cost and excellent in reliability.
