Abstract

(57) [Abstract] [Purpose] To provide a rotating structure capable of preventing an erroneous operation and an erroneous operation by giving an appropriate operation feeling and a rotating torque to the rotation of the crown. The rotating mechanism of the present invention comprises a crown 1, a pinion 5 attached to the crown 1, an inner register ring 6 having a gear meshing with the crown 1, and a claw 9b protruding from an inner frame 9 and engaging with the pinion 5. It consists of Nail 9b
By engaging with the pinion 5, the rotation of the pinion is suppressed, and a click operation feeling and a rotational torque are generated with respect to the rotation of the crown 1.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotating structure of an inner register ring provided inside a watch glass included in a diver watch or the like, and more particularly to a rotating structure of an inner register ring caused by rotation of a crown.

[0002]

[Prior Art]

 As a conventional rotating structure of this kind of inner register ring, there is one disclosed in Japanese Utility Model Laid-Open No. 48-20469. In this rotating structure, a gear is provided at the tip of the operation button, and this gear meshes with a gear provided on the inner register ring, whereby the inner register ring is rotated by the rotation of the operation button.

[0003]

[Problems to be solved by the device]

 In the above-described conventional rotating structure, since there is no means for restricting the rotation of the operation buttons and the like, the inner register ring may move during use. Also, when rotating the inner register ring to set it to the desired position, it was not possible to obtain a proper feeling of operation and rotation torque, so it may be rotated too much, and it is not easy to get used to setting it quickly. Was needed.

The present invention has been made in view of the above problems, and an object thereof is to provide a rotating structure of an inner register ring capable of preventing an erroneous operation and an erroneous operation by giving an appropriate operation feeling and a rotation torque for the rotation of the crown. To provide.

[0005]

[Means for Solving the Problems]

 The rotating structure of the inner register ring of the present invention is such that the crown, the pinion that rotates by the rotation of this crown, the inner register ring that has the gear that meshes with this pinion, and the pinion that protrudes from the inner frame that positions and fixes the movement are engaged. Then, it is characterized by comprising a claw for suppressing the rotation.

[0006]

[Action]

 In the rotating structure of the present invention, the rotation of the pinion and the crown is suppressed by the engagement of the claw protruding from the inner frame with the pinion rotating with the crown. Particularly, in the present invention, the claw engages with the teeth of the pinion to give a click feeling, and the elasticity of the claw presses the pinion teeth to generate an appropriate rotational torque. ..

【Example】

 FIG. 1 is a sectional view showing a rotating structure of an inner register ring according to an embodiment of the present invention, and FIG. 2 is a sectional view showing a structure seen from the direction of the rotation axis of the crown. Reference numeral 1 is a crown, which is rotatably inserted into a pipe 3 inserted into a lateral hole 2a of a case 2 through a packing 4.

Reference numeral 5 is a pinion fixed to the crown 1 and rotating together with the crown 1.

Reference numeral 6 denotes an inner register ring, which is provided inside the glass 7 attached to the upper part of the case 2, and is placed on the stepped portion 2 b inside the case 2 via a packing 8. A gear 6 a that meshes with the pinion 5 is provided on the lower surface of the inner register ring 6.

Reference numeral 9 denotes a middle frame for positioning and fixing the movement 10, which is made of synthetic resin. The inner frame 9 is provided with a recess or notch 9a for escaping the pinion 5, and a claw 9b protruding so as to engage with the pinion 5 is formed therein. As shown in FIG. 2, the claw 9b in this embodiment has a slope 9c protruding from the upper end of the middle frame 9 and having its upper surface inclined toward the tip. The inner frame 9 is positioned by the pipe 3 or a winding stem pipe (not shown) so as not to rotate.

In the rotating structure having the above structure, when the fuse 1 is rotated so that the pinion 5 rotates counterclockwise in FIG. 2, the inner register ring 6 meshing with the pinion 5 rotates leftward in FIG.

At this time, the pinion 5 rotates so as to push the claw 9b engaged with the pinion 5 downward as shown by the dotted line in FIG. 2, the teeth of the pinion 5 are disengaged from the claw 9b, and the next tooth is clawed. A click feeling occurs when engaging with 9b.

The claw 9b in the present embodiment allows only the left rotation of the pinion 5 in FIG. 2 depending on its forming position and shape, and when the pinion 5 rotates right, it does not elastically deform like the case of left rotation, and the pinion 5b is rotated. It is set so as to prevent the right turn of No. 5.

The position of the claw 9b may be lowered or the shape and length of the claw 9b may be changed so that only the right rotation of the pinion 5 is permitted, and the right and left both rotations are possible. You can also Further, the click operation feeling can be changed by increasing or decreasing the number of teeth of the pinion 5.

[0015]

[Effect of the device]

 According to the present invention, by suppressing the rotation of the pinion by the claw protruding from the inner frame, it is possible to generate an appropriate click operation feeling and a rotation torque, and prevent an erroneous operation or an erroneous operation. Further, since the inner frame is provided with the claws, the number of parts does not increase and it is possible to provide a structure excellent in versatility.
