Description

【考案の詳細な説明】本考案は時計などの枠に関するものである。[Detailed explanation of the idea] The present invention relates to frames for watches and the like.

従来、たとえば置時計の枠にはその底部に台板

じ止めによる取付方法はねじを必要とするために
部品点数が多くなり製造、組立も面倒である。 Traditionally, for example, a table clock frame has a base plate attached to the bottom of the frame using screws, but this method requires screws, which increases the number of parts and makes manufacturing and assembly troublesome. .

本考案の目的は部品点数が少なく、製造、組立
が容易である時計などの枠を提供することにあ
る。 The purpose of the present invention is to provide a frame for a watch or the like that has a small number of parts and is easy to manufacture and assemble.

以下本考案の実施例を図面について説明する。 Embodiments of the present invention will be described below with reference to the drawings.

第１図においてたとえば時計の枠体１は、その
底部に台板２を取付手段により着脱可能に取付け
るものである。 In FIG. 1, for example, a frame 1 of a timepiece has a base plate 2 removably attached to its bottom by means of attachment means.

である。 Here, the specific structure of the attachment means will be explained. As shown in FIGS. 1 and 2, the bottom of the frame 1 has a rectangular mounting hole 3 and a locking groove 4, which is a locking part.
5 is provided. The locking grooves 4 and 5 are formed in a direction perpendicular to the longitudinally opposing pieces of the mounting hole 3, and have a V-shape in the examples shown in the first and third figures.

圧するように枠体１の底部に取付けられる。 A pair of mounting pieces 6 and 7 are provided at predetermined positions facing the mounting hole 3 on the base plate 2, and these mounting pieces can be inserted into and removed from the mounting hole 3 of the frame body 1 and rotated freely. Each mounting piece 6, 7 is formed in an inverted L shape, and the bent portions 6a, 7a extend horizontally and are elastically deformable. Engagement parts 6b and 7b which can be engaged with and disengaged from the engagement grooves 4 and 5 of the frame body 1 are formed on the lower surfaces of the bending parts 6a and 7a. Engagement parts 6b, 7b
As shown in FIG. 4, the entire lower surface of the bent portion 6a may be formed into a mountain-shaped protrusion, or as shown in FIG.
Alternatively, it may have a semicircular cross section. The height h (Fig. 4) from the top surface of the base plate 2 to the protrusions 6b and 7b is determined by the thickness t of the bottom of the frame 1 (the third
It is somewhat smaller than the one shown in Figure). Therefore, the bending part 6
a, 7a are protrusions 6b, 7b as shown in FIG.
is attached to the bottom of the frame 1 so as to press against the locking grooves 4 and 5 of the frame 1 with a constant spring force.

つぎに台板２を枠体１に取付ける操作について
説明する。 Next, the operation for attaching the base plate 2 to the frame body 1 will be explained.

突部６ｂ，７ｂは係止溝４，５に一定のばね力を
もつて係合する（第３図）。この結果、台板２は
枠体１に取付けられる。 First, when the base plate 2 is moved in the direction of the arrow from the position shown in FIG. 1 and the mounting pieces 6 and 7 are inserted into the mounting holes 3 of the frame 1, the mounting pieces are moved to the position shown by the chain line in FIG. is set. Therefore, if the base plate 2 is rotated, for example, 90 degrees clockwise (in the direction of the arrow in Figure 2),
The bending parts 6a and 7a of the mounting pieces 6 and 7 are also rotated in the same direction and at the same angle, and at the position shown by the solid line in FIG.
The protrusions 6b, 7b engage with the locking grooves 4, 5 with a constant spring force (FIG. 3). As a result, the base plate 2 is attached to the frame 1.

台板１を外すには、上記の操作と逆の手順で行
えばよい。 To remove the base plate 1, the procedure described above may be reversed.

い。 Note that as a means for locking the mounting piece to the frame, the sixth
As shown in the figure, an engagement groove 16b is formed as an engagement part on the lower surface of the bending part 16a, a protrusion 14 is provided as a engagement part on the bottom of the frame 1, and the engagement groove becomes a engagement protrusion. It may also be removable. Alternatively, as shown in FIG. 7, the mounting piece 26 may be formed into a T-shape and the bent portions 26a and 26b may be integrated. Furthermore, the bending parts of the mounting pieces do not necessarily have to be paired, and may be one as long as it is possible to attach the base plate 2 to the frame 1. The present invention is not limited to clock frames.

以上説明したように本考案によれば、構成が簡
単となり、枠体に対する台板の取付け、取外しが
容易に行え、製造が簡単となるなど実用上の効果
は大きい。 As explained above, according to the present invention, the structure is simple, the base plate can be easily attached to and removed from the frame, and the manufacturing is simple, which has great practical effects.
