Embodiment approach 1

[0043] figure 1 Among them, the watch 10 of the present invention has: a watch body 20 housing a time display unit and a movement in a case; and a wristband 30 for wearing the watch body 20 on a wrist. In addition, it also has a clockwork twist 40 for adjusting the time.

[0044] This table 10 exemplifies the lengthwise design in which the width in the direction from 3 o'clock to 9 o'clock in the second direction is narrower than the length in the direction from 12 o'clock to 6 o'clock in the first direction. Table, is a very popular design.

[0045] Then refer to Figure 2 ~ Figure 4 , the structure of the table realizing the vertical design of the present invention will be described.

[0046] figure 2An exploded perspective view of watch body 20 is shown. The watch body 20 has a main body 50 constituting a watch case, and a substantially rectangular opening that penetrates up and down is provided in the main body 50 . On the opening 50A of the main body 50, the dial p...

Embodiment approach 2

[0092] Next, Embodiment 2 of the present invention will be described with reference to the drawings. Embodiment 2 is based on the technical idea of ​​Embodiment 1, and has the feature of simplifying the shape of the elastic middle frame. The same functional components as in Embodiment 1 are described with the same reference numerals.

[0093] Figure 8 Shown is a partial cross-sectional view of the movement holding structure of the watch according to the second embodiment. exist Figure 8 In , the movement holding structure in the 6 o'clock direction is given as an example for illustration. exist Figure 8 Among them, the first middle frame 190 is provided with: a movement guide portion 191A abutted against the movement fixing portion 61A of the movement 60; a flange-shaped protruding profile portion 192; The protrusion 196 is fixed. The fixing protrusion 196 corresponds to the first embodiment described above (refer to Figure 4 ) shows the fixing protrusions 92C, 92D....

Embodiment approach 3

[0099] Next, Embodiment 3 of the present invention will be described with reference to the drawings. Compared with the first and second embodiments, the third embodiment is characterized in that the fixing structure of the rear cover 70 to the main body 50 adopts a screw fixing structure. For the 1st middle frame and the 2nd middle frame, because and embodiment 1 (refer to Figure 2 ~ Figure 6 ) are the same, so the description is omitted, and the components with the same function are described with the same symbols.

[0100] Figure 9 Shown is a partial sectional view of the movement holding structure of the watch according to Embodiment 3, Figure 9 The movement holding structure in the 6 o'clock direction is exemplified on behalf of this embodiment. Figure 9 Among them, an internal thread 56 is provided on the main body 50 from the direction of the rear cover.

[0101] Four internal threads 56 are provided at the four corners of the main body 50, and the rear cover 70 ...

Abstract

It is an object of the present invention to provide a timepiece movement holding structure and a timepiece which make it possible to realize a design that is elongated in the longitudinal direction or the lateral direction. The timepiece movement holding structure comprises a first casing frame which holds the end part of the movement in the 6 o'clock direction, and a second casing frame which holds the end part of the movement in the 12 o'clock direction. The widths of the first casing frame and second casing frame in the 3 o'clock to 9 o'clock direction are set substantially the same as the width of the movement in the 3 o'clock to 9 o'clock direction. These casing frames and are disposed substantially within the width of the movement in the 3 o'clock to 9 o'clock direction, and the movement is held in the plane direction between the interior-forming case body portions through of the case body and the first casing frame and second casing frame. The movement is held in the sectional direction between the case body and back cover as a result of the first casing frame and second casing frame being pressed in the sectional direction of the movement by an inside main surface or back cover fixing parts provided to the back cover.

Description

technical field [0001] The present invention relates to a movement holding structure of a watch, and more specifically, to a movement holding structure and a watch capable of realizing a narrow design in the direction of 3 o'clock to 9 o'clock or the direction of 12 o'clock to 6 o'clock. Background technique [0002] The movement holding structure of the existing watch is well known (for example: refer to Patent Document 1), that is, in the structure that the movement is fixed to the watch case by the middle frame made of synthetic resin, the middle frame It is integrally formed along the entire circumference of the plane direction end of the movement, and a flange portion extending in a flange shape and its outer peripheral portion are formed along the entire circumference, and a movement card for holding the movement in the up and down direction is also formed. The joint part and the spring part extending downward are provided with a space part in the spring part to ease t...
