Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting structure for attaching, for example, the ring and legs of a clock to a clock case.

(Prior Art) Conventionally, for example, in order to attach the ring post of a table clock to a watch case, a threaded rod is integrally protruded from the ring post, and this threaded rod is inserted into a mounting hole in the watch case. A nut was screwed into this thread from the inside of the watch case (Utility Model Publication No. 5444, 1929).

As another example, in order to attach the legs of a table clock to a watch case, a female thread is drilled into the legs.
From the inner side of the watch case where the mounting holes are made,
You can install the screw by inserting it through this mounting hole and screwing its tip into the female threaded part of the leg, or as another example, insert the threaded rod attached to the female threaded part of this leg from the outside of the mounting hole of the watch case. It was inserted inward and a nut was screwed onto the tip of the threaded rod that protruded inside the watch case.

(Problem that the invention aims to solve) However, all of the conventional mounting structures use screws and nuts, which takes time and effort to tighten. The operation is extremely complicated, and as table clocks become smaller, this mounting structure may become practically impossible.

Therefore, an object of the present invention is to provide a mounting structure that allows an object to be mounted, such as a watch leg, to be mounted easily and quickly even in a narrow space without using screws or nuts to a frame such as a watch case.

(Means for solving the problem) The feature of the present invention is that a narrow column is protruded from the object to be attached, such as the foot of a table clock, and the tip of the column is larger than the column. A mounting hole is provided in the frame such as a watch case, and the size of the mounting hole is large enough to allow the extension to pass through. That is, the width of the mounting hole is such that the object to be mounted itself cannot be inserted through the mounting hole, but the column and the expanded portion can be inserted through the mounting hole. The inner frame, which is inserted rearward into the inner surface of the frame, is provided with a locking pawl that engages with the outer periphery of the column that protrudes inward from the outside of the mounting hole of the frame.

(Function) Therefore, by inserting the expanded portion of the object to be attached and the column inward from the outside of the mounting hole of the frame and engaging the locking claw of the middle frame with the column, the object to be attached is The extension part prevents the extension from coming off and can be reliably attached to the frame.

(Example) The drawing shows an example in which the present invention is applied to a table clock, and this is an example in which a ring post and a leg, which are examples of objects to be attached, are attached to a clock case, which is an example of a frame. It is. In FIG. 1, a dial plate 3 is provided on the front side of a watch case 2 of a table clock 1, and a ring post 4 is installed at the top of the dial plate 3. A dial plate 3 is installed on the top of the dial plate 3, and a foot plate and a ring post 4 are installed on both sides of the bottom of the watch case. 5,5 are provided.

And since the mounting structure of the ring post 4 and legs 5, 5 to the watch case 2 are all substantially the same structure,
The specific structure of the mounting state of the ring post 4 will be described below.

As shown in the second figure, the ring post 4 has a ring 42 attached to a base 41, and a narrow locking post 43 is vertically installed at the center of the lower surface of the base 41. An enlarged extension 44 is integrally formed at the lower end of the column.

Furthermore, a mounting hole 21 is formed at the top of the watch case 2. Of course, the transport post 4 must be wide enough to prevent insertion.

Furthermore, since the watch case 2 is ring-shaped, the outer surface of the inner frame 6 is also ring-shaped so that it can come into contact with or approach the inner surface of the inner frame, and as shown in the second figure, the inner frame 6 has a ring-shaped outer surface. The inner frame 6 has two locking claws 61, 6.
1a is bored, and the locking column 43 of the ring post 4 is held and engaged between the claws.

Therefore, in order to attach the ring post 4 to the watch case 2, the extended portion 44 of the ring post 4 and the column body 43 are inserted into the mounting hole 21 of the watch case 2, and the engagement of the middle frame 6 is inserted into the position of the column body 43. When the end openings of the locking claws 61 and 61a are aligned and the inner frame 6 is inserted inward from the open end of the watch case 2, both of the locking claws are attached to the column 43 as shown in the third figure.
Therefore, the ring post 4 is prevented from coming off by the expanded portion 44, and the ring post 4 can be easily attached to the watch case 2.

The mounting structure of the foot 5 is as shown in Figure 4, with a pillar 51 and an extended portion 52 protruding from the top of the foot, and this extended portion and the pillar 5 fit into the mounting hole of the watch case 2. 22, and is locked and attached by the locking claws 62 of the middle frame 6.

(Effects of the invention) As described above, according to the present invention, there is no need for screws or nuts as in the conventional case, and by simply inserting the object to be attached into the frame and inserting the inner frame into the frame, the object to be attached can be attached to the frame. Since it can be attached to the frame, the attachment operation can be performed extremely quickly, and the attachment operation can also be carried out easily in a narrow space.
