Description

[Detailed description of the invention] The present invention relates to an improvement in the connection structure between the rod and the pendulum body of a pendulum clock, and in particular, the connection part between the rod and the pendulum body is located at a position offset in the front and back direction with respect to the support part of the rod. The present invention relates to a pendulum device configured such that the pendulum body is not tilted in the front-back direction of a watch body.

In the pendulum device of a conventional pendulum clock,
The connecting part between the swinging rod and the pendulum body was provided in the vertical direction of the swinging rod support part, and the structure in which the pendulum body was hung on the swinging rod was mainly used, so that the pendulum body was not tilted with respect to the clock body. In addition, in most cases, the connecting part between the swinging rod and the pendulum body was housed inside the watch case.

The purpose of the present invention is to provide a structure in which the rod and pendulum are connected so that the connecting part between the rod and the pendulum is exposed to the outside in the front-rear direction of the watch case, and the pendulum can swing without tilting with respect to the watch body. It is to be.

In order to achieve the above-mentioned object, the present invention includes a swinging support part provided inside the timepiece body, and a first engaging part that engages with the pendulum body is connected to a swinging rod extending in the front-rear direction outside the timepiece body, and a pendulum body having a second engaging part closely coupled with the first engaging part, the center of gravity of which is located approximately in the vertical direction of the swing support part when the engaging parts are coupled to each other; One of the first engaging part and the second engaging part is formed with an engaging protrusion having a surface that is formed thinner toward the tip, and the other has an inner surface that can come into close contact with the engaging protrusion. An engagement recess is formed;
The pendulum body is characterized by being able to swing back and forth without tilting the clock body.

The present invention will be described below based on an embodiment of the present invention shown in the drawings.

FIG. 1 shows an external view of the pendulum clock according to the present invention.
is installed. On the front of the watch body 2 are the second and third
As shown in the figure, an elongated hole 6 is formed at the position of the 12 o'clock indicator, and from the elongated hole 6 the first
The engaging portion 10 is exposed. Support part 12 of swing rod 8
is provided on the top surface of the timepiece mechanism body 14, and the swinging rod 8 is oscillated by electromagnetic coupling between a permanent magnet fixed to the swinging rod 8 and a drive coil fixed to the timepiece mechanism body 14, although illustration is omitted. Driven. Further, the first engaging portion 10 of the swinging rod 8 has a trapezoidal shape that is tapered upward.

The pendulum body 4 is composed of a link part 15 that surrounds the side surface of the circular watch body 2, and a second engaging part 16 that can be removably tightly coupled to the swinging rod 8 on the front surface of the watch body 2. A coupling hole 18 into which the first engagement part 10 of the swing rod 8 can be fitted is formed in the second engagement part 16 of the pendulum body 4, and above the coupling hole 18, the first engagement part 10 is fitted. The inner surface has substantially the same shape as the inner surface.

Since the illustrated embodiment is configured as described above, when the pendulum body 4 is coupled to the swinging rod 8, the second engaging portion 16 of the pendulum body 4 is moved in the direction of the arrow A as shown in FIG. By moving the first
The engaging portion 10 is inserted into the coupling hole 18 of the pendulum body 4, and then the pendulum body 4 is moved in the direction of arrow B. As a result, the first engaging portion 10 of the swinging rod 8 and the coupling hole 18 of the pendulum body 4 are tightly coupled, and the center of gravity of the pendulum body 4 is disposed approximately in the vertical direction of the support portion 12 of the swinging rod 8. As a result, even though the joint between the pendulum rod 8 and the pendulum body 4 is located at the front of the clock body 2, the pendulum body 4 does not tilt with respect to the clock body 2, but moves in the direction of the arrow in FIG. Can perform pendulum movements.

Further, in the illustrated embodiment, the back surface of the second engaging portion 16 of the pendulum body 4 is formed in a hemispherical shape, and the hemispherical back surface plays the role of an indicator indicating 12 o'clock on the dial.

In addition, in the illustrated embodiment, the swinging rod 8 is provided with a first engaging portion 10.
A second engaging portion 1 is provided on the pendulum body 4.
Although an engaging recess is provided as 6, a coupling structure in which the swinging rod 8 is provided with an engaging recess and the pendulum body 4 is provided with an engaging protrusion has the same effect as the illustrated embodiment. Further, in the illustrated embodiment, the first engaging protrusion 10 is formed into a substantially trapezoidal shape, but this may be in the shape of a square, rectangular parallelepiped, cylinder, prism, hemisphere, cone, or pyramid. Any structure may be used as long as the swinging rod and the pendulum are in close contact with each other in the swinging direction of the pendulum and in a direction perpendicular to the swinging direction.

As explained above, according to the present invention, either the first engaging part of the swinging rod or the second engaging part of the pendulum body has an engaging convex having an inclined surface formed narrowly toward the tip. The other side is formed with an engaging concave portion whose inner surface can be brought into close contact with the engaging convex portion, so that even though the center of gravity of the pendulum body is not located below the connection between the swinging rod and the pendulum body, First, the pendulum body does not tilt in the front-back direction of the watch body.

Furthermore, the present invention can provide a timepiece with a novel and unprecedented configuration in which the pendulum body surrounds the side surface of the timepiece body, and the joint between the pendulum and the pendulum body functions as a time indicator on the dial.
