Description

[Detailed explanation of the idea] This invention relates to a clock pendulum.

In conventional clock pendulums made of synthetic resin, the pendulums had to be manufactured for each model in order to accommodate the differences in length of the pendulums depending on the model of the watch.

For this reason, it is necessary to create a new mold, etc., which leads to an increase in manufacturing costs, and furthermore, the complexity of parts management becomes a problem.

The present invention solves the above-mentioned conventional problems, and its purpose is to provide a clock pendulum with reduced manufacturing costs and easy parts management.

In order to achieve the above object, the present invention provides a clock pendulum consisting of a swinging rod and a swinging ball. is formed with a retaining means capable of engaging and holding the two engaging parts of the swinging rod, the diameter of the swinging ball itself is set to be at least twice the distance between the engaging parts of the swinging rod, and the engaging means is provided on the center line of the pendulum, and a space capable of accommodating at least one engagement part interval of the swing rod is provided in a direction different from the fulcrum direction of the pendulum than the engagement means, and the swing ball holding means It is characterized in that the length of the swinging rod can be changed by selectively engaging one of the plurality of engaging parts of the rod.

Preferred embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a plan view of the swinging rod, and FIG. 2 shows a side view thereof.

Further, FIG. 3 shows a cross-sectional view taken along the line A--A in FIG. 1.

The swinging rod 10 has hook portions 12 formed at both ends that can be engaged with the swinging rod, and engaging portions 14 are formed at regular intervals so as to surround a connecting rod portion 16 consisting of three pipes. .

This retaining portion 14 has a cross-sectional shape as shown in FIG. 3, has a decorative effect, and is capable of engaging with an engaging portion 34 formed on the swinging ball 20, which will be described later.

In addition, in this swinging rod 10, hook portions 12 are formed at both ends, so there are two parts depending on the cut point of the swinging rod 10.
This method is convenient for manufacturing and managing parts.

As shown in the assembly side view of FIG. 9, the swinging ball 20 is
It consists of a 0 and a ball back 40.

FIG. 4 shows a plan view of the main body 30 seen from the inside, and FIG. 5 shows a sectional view taken along the line B--B.

A mating surface 32 with the main layer 40 is formed inside the main body 30, and the mating surface 32 has a semicircular groove 32a into which the connecting rod part 16 can be inserted and clamped, and a groove 32a of the main layer 40, which will be described later. A claw clamp i32b that can engage with the clamp claw 42b is formed.

Further, inside the main body 30, there are both upper and lower rising guide portions 34 as retaining means capable of engaging with the engaging portion 14 of the swinging rod 10.
a.

34b and a side rising guide portion 34c are formed,
The engaging portion 14 of the swinging rod 10 can be engaged at two locations, the upper and lower rising guide portions 34a and 34b.

The distance between the upper and lower rising guide portions 34a and 34b is equal to the distance between the engaging portions 14 of the swinging rod 10.

The diameter of the swinging ball 20 is set to be twice or more the interval between the engaging parts 14 of the swinging rod 10, and both the upper and lower rising guide parts 34a and 34b of the main part 30 are located above the center (as shown in FIG. 4). It is set to have a space on the lower side for at least one interval of the engaging portion 14.

FIG. 6 shows a plan view of the main layer 40 viewed from inside, and FIG. 7 shows a cross-sectional view taken along the line CC.

A mating surface 42 with the main layer 40 is formed inside the main layer 40, and the mating surface 42 has a semicircular groove 42a in which the connecting rod part 16 can be inserted and clamped, and a claw clamping part of the main layer 30. Groove 32
A clamping claw 42b that can be engaged with the clip 42b is formed.

The present invention has the above configuration, and its operation will be explained below.

In the present invention, the swinging rod 10 is provided with an engaging portion 14 of an arbitrary length.
Cut it and use it.

The pendulum is connected by engaging the clamping claw 42b of the main layer 40 with the clamp ll32b of the main 30, thereby sandwiching the main 30 and the main layer 40, and at the same time inserting the pendulum between the main 30 and the main layer 40. The holding part 14 of the swinging rod 10 is connected to both the upper and lower rising guide parts 34a, 34b of the main 30 and the main 30,
A pendulum is connected between the grooves 32a and 42a of the main layer 40 as shown in FIGS. 8 and 9.

Since the pendulum of the present invention is connected in this way,
When the engaging portion 14 at the tip of the swinging rod 10 is engaged with both the upper and lower rising guide portions 34a and when it is engaged with the upper and lower rising guide portions 34b, two types of pendulum lengths are obtained.
By changing the cutting point of the pendulum, it is possible to obtain pendulums of many lengths.

Further, in this embodiment, the diameter of the swinging ball 20 itself is set to be at least twice the interval between the engaging parts 14 of the swinging rod 10, and the swinging ball 20 that engages and holds the retaining part 14 is A space corresponding to at least one interval of the engaging portion 14 is provided in the direction of the groove 32a from the plane center of the swinging ball 20 for the joining means.

As a result, no matter where the connecting rod portion 16 of the swinging rod 10 is cut, the cut surface will not protrude outside the outer diameter of the swinging ball 20.

In addition, in the illustrated embodiment, the engaging portion 14 of the swinging rod 10
Although the spacing and the spacing between the upper and lower rising guide portions 34a and 34b, which are means for holding the swinging ball 20, are set equal,
By setting the spacing between the retaining portions 14 of the swinging rod 10 to be half the distance between the upper and lower rising guide portions 34a and 34b, the length of the swinging rod 10 can be changed to more types.

As described above, in this invention, pendulums of different lengths can be obtained from one type of component, instead of manufacturing pendulums for each model of watch as in the past.
Manufacturing costs are reduced.

Furthermore, the management of parts of the pendulum can also be simplified.
