Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention mainly relates to a timepiece, a display for ornaments, an interior clock, and other rope art mechanisms aiming at visual effects.

(Prior Art) In the past, a watch or a decorative item whose movement is changed as if the pattern using such a flexible rope art is lived as a whole should not have a real existence, and should have a unique functionality. I couldn't.

(Technical problem) Therefore, the present invention has been made in view of the prior art, and produces a unique design and function as a timepiece or a decorative article,
The technical challenge is to give the viewer enjoyment.

(Technical Means) In the present invention, in order to solve the above-mentioned technical problems, the outline (outline) is set and arranged and fixed so that an appropriate pattern is preliminarily provided on the timepiece dial surface or various decorative displays. By driving a specific point on the rope-shaped flexible member, the entire design is changed to be alive. Specifically, it has the following configuration as shown in the illustrated embodiment.

Regarding the first embodiment (FIGS. 1 to 7).

Reference numeral 1 is a flexible member arranged on the dial surface 2 of a watch or the like in a pattern shape so as to outline the outline of a doll, an animal, or the like. In this embodiment, the flexible member 1 is used. As the material, a rope-shaped material, such as a cord, which is appropriately braided in various colors and thicknesses is used.

Although the flexible member 1 is arranged on the dial face 2 of the timepiece in the present embodiment, the present invention is not limited to the timepiece, but a display or other ornaments for producing a visual effect or the like. Of course, it may be applied to.

Reference numeral 3 is a fixing member that is fixed to the dial surface 2 to maintain the outline of the rope-shaped flexible member 1, and serves as an immovable fixing point A as a specific point of the flexible member 1. It works.

4 is a movable band zone in a flexible and free state other than the fixed point A of the flexible member 1, and a plurality of driving points B as specific points of the movable band zone 4 are fixed by ropes with rubber packings 7 interposed therebetween. The shaft 5 is fixed by the pin 6 for use.

The degree of deformation can be changed depending on the length of the rope fixing pin 6 penetrating inside the flexible member 1.

Reference numeral 8 denotes a through hole formed on the dial plate surface 2 so as to face the driving point B. A bush 9 functioning as a bearing of the shaft 5 is fitted in the through hole 8 so that a through hole of the bush 9 is formed.
A shaft 5 fixed to the flexible member 1 is rotatably inserted in 9A. Reference numeral 10 is a locking step portion of the shaft 5, 11 is a ring-shaped groove, and the shaft 5 is inserted into the bush 9 by the locking step portion 10 and an E-ring 12 fitted in the ring-shaped groove 11. It is designed to be supported.

Reference numeral 13 is a crank arm having a suspension hole 13A, and a tip portion 5A of the shaft 5 is fixed by caulking or the like to a mounting hole 13B formed at the center or end of the crank arm 13.

Then, the crank arm 13 is rotated in the left-right direction about the shaft 5 as a central axis, so that the flexible member 1 becomes a body around the driving point B as a unit, and the arrow P or Q.
Movable zone 4 in a free state by declination in the direction
Can flexibly bend and twist.

Reference numeral 14 is a connecting rod for connecting the crank arms 13 to each other. The connecting rod 14 is loosely engaged with one of the engaging holes 13A of the crank arm 13 and the connecting rod 14 On the other end of the other crank arm
The crank arms 13 are engaged with each other by engaging one of the 13 holes 13A for suspension, so that the crank arms 13 rotate in unison with each other (see FIG. 2). All the drive points B of 1 are driven at the same time.

A drive motor 15 has a motor pinion 16 fitted to its output shaft 15A.

Reference numeral 17 is a crank gear meshed with the motor pinion 16, and a hole 17B of the crank gear 17 is disengaged from a crank shaft 17A.
One end 18A of the driving rod 18 is loosely engaged and the other end 18B is loosely engaged with either one of the engaging holes 13A of the crank arm 13.

By the operation of the drive motor 15, the crank gear 17 rotates in the arrow R direction, and the drive rod 18 moves the arrow S.
And the reciprocating motion in the T direction, and the crank arm 13 is pivotally rotated. (Refer to FIG. 5) 19 is a timepiece main body, and instead of obtaining the drive output by the drive motor 15, the rotary drive force of the crank arm 13 may be directly obtained from the timepiece main body 19, or each may be an independent mechanism. good.

(Operation) The above technical means works as follows.

In the present embodiment, the design of the rope-shaped flexible member 1 is set in an elephant shape, and first, the crank gear 17 is driven to rotate in the arrow R direction by the operation of the timepiece main body 19 or the drive motor 15.

At that time, the driving rod 18 is reciprocally moved in the arrow S and T directions, and one of the several crank arms 13 is forcibly rotated alternately to the left and right. At this time, the shaft 5 fixed to the mounting hole 13B of the crank arm 13 forcibly rotates the drive point B of the flexible member 1 integrally in the arrow P or Q direction. Further, all the crank arms 13 are driven in unison with each other via the connecting rod 14.

Thus, as shown in FIG. 7, some driving points B of the movable belt zone 4 between the fixed points A of the rope-shaped flexible member 1 are rotated in the direction of the arrow P or Q by the declination, and the flexible member is moved. The movable band zone 4 of 1 can be flexibly deformed in alternate directions to the right and left to appropriately change the entire pattern.

Regarding the second embodiment (FIGS. 8 to 9).

In the second embodiment, substantially the same parts as those in the first embodiment are designated by the same reference numerals.

The feature of this embodiment is that the pattern formed by the flexible portion 1 having a rope shape is arranged so as to have a crocodile shape. 20
Is a core body in which the drive point B and the joint point C corresponding to the mouth portion L of the crocodile are connected and inserted, and the drive point B of the core body 20.
It is possible to cause an operation of opening or closing the mouth of the crocodile on the dial surface 2 by rotating the declination via the.

Reference numeral 21 is an accessory such as a bird or a doll attached to the flexible member 1 which is one of the driving points B,
Due to the eccentric rotation of the drive point B, the flexible member 1 is flexibly deformed, and at the same time, the accessory 21 becomes a body and can eccentrically rotate.

Reference numeral 22 denotes a sphere which is arranged between the fixed points A and represents the eyes of the crocodile, and the crocodile's eyes may be operated by rotating the sphere 22 as the driving point B. The number of drive points B between the fixed points A is arbitrary as in the first embodiment.

(Effect) Therefore, the present invention has the following unique effects.

In particular, the animal dolls and the like are appropriately contoured and flexible members are arranged in a picture shape, and these are flexibly driven so that only specific points are connected to each other. There is a great amount of real benefits, such as the ability to fully exhibit the design and functional peculiarity as a timepiece or a decorative display, and to give the viewer enjoyment.
