Description

【考案の詳細な説明】本考案は時計などにおける前面カバーの取付け
構造に関するものである。[Detailed Description of the Invention] The present invention relates to a structure for attaching a front cover to a watch or the like.

従来見返しにガラスを取り付けるには、ガラス
の見返しのガイドに受ゴム座を介在させて対接さ
せ、ガラス縁によつてガラスの外れを防止してい
る。このために受ゴム座，ガラス縁などの部品点
数が多く、取り付けに手間がかかり、ガラスのが
たつきが生じ、コスト高となつていた。 Conventionally, when attaching glass to a endpaper, a rubber receiver is interposed between the guide of the glass endpaper and the glass is brought into contact with the guide, and the glass edge prevents the glass from coming off. As a result, the number of parts such as the rubber seat and the glass rim is large, making installation time-consuming and causing the glass to rattle, resulting in high costs.

本考案は上記従来の欠点を除去し、部品手数が
少く、取り付けが容易であり、前面が簡素ですつ

る。 In FIGS. 1 and 2, the outer peripheral frame 1 of the timepiece has a "mouth" shape, and a dial body 2 is fitted on the inner periphery thereof. The dial body 2 is made of synthetic resin such as ABS or polyethylene, and as shown in Figures 3 and 4, has a dial holder 2a in the center and a U-shaped cross section projecting toward the back on the outer periphery of this dial holder. A shaped back part 2b and a dial receiving part 2 continuous from the outer periphery of the back part.
c, a facing part 2d rising from the outer periphery of the receiving part 2c toward the front, and extending toward the back from an edge 2e forming the front end surface of the facing, and the outer peripheral frame 1

is provided. In this example, since the outer shape is square, grooves are provided at each corner, so that the front end of the facing part 2d of the facing body 2 can be expanded as shown in the third figure. A locking groove 4 is provided on the inner peripheral surface near the front end of the facing part 2d, and the outer periphery of the front cover 5 fits into this groove. A pointer through hole 6 is provided at the center of the dial receiving portion 2a. Dial plate holder 2a
A watch mechanical body 7 is fixed to the back of the watch, and a dial 8 is fixed to the front. A pointer 10 is attached to the tip of a pointer shaft 9 protruding from a timepiece mechanical body 7. Further, the fixing piece 2g is provided with a fixing hole 2h.

円周の係止溝１４に嵌合している。 In another example shown in FIG. 5, the outer peripheral frame 11 has a circular outer shape, and the facing body 12 fitted in this frame also has a circular shape. In this example, four kerfs 13 are formed in this facing part 12d so that its front end can be expanded. Reference numeral 15 denotes a front cover, and the outer periphery of this cover fits into a locking groove 14 on the circumference of the facing part.

る。 Next, when attaching the front cover, first fix the watch mechanism body 7 to the back of the dial holder 2a of the dial body 2 . A dial plate 8 is placed on the front of the dial plate holder 2a.
is fixed, and the pointer 10 is attached to the pointer shaft 9 protruding from the through hole 6. Since the front end of the facing part 2d is widened by the cut groove 3, the front end of the facing part 2d is tightened while fitting the outer periphery of the front glass 5 into the locking groove 4, and the cut groove 3 is expanded. 1. Bring them into a facing state as shown in the figure. In this state, the front end of the facing body 2 is inserted from the back side of the outer circumferential frame 1, and the outer surface of the attachment portion 2f is brought into contact with the inner surface of the outer circumferential frame 1. In this state, the fixing piece 2g is in contact with the back surface of the outer peripheral frame 1, so for example, a screw 1 is inserted into the fixing hole 2h.
6 and fix it to the frame 1. Since the facing portion 2d is in a contracted state and its outer periphery is tightly surrounded by an outer peripheral frame, the facing grooves 3 cannot be closed. Therefore, the front cover 5 is attached in the locking groove 4 so as not to be able to escape. The attachment of the front cover 15 in the one shown in FIG. 5 is completely similar to that described above.

以上述べたように本考案によれば、部品点数が
少く、取り付けが容易であり、コストの低減を達
成できる。また前面カバーの取り付け状態は強固
で安定しており、かつ前面が簡素ですつきりして
いるなど、多くの優れた効果がある。 As described above, this invention has many excellent advantages, such as fewer parts, easier installation, and reduced costs. The front cover is firmly and stably attached, and the front is simple and clear.
