Abstract

PURPOSE:To give particular movement to hands and give dynamic ornamental effect by driving a second hand having an ornamental piece loosely fitted to a rotation axis such as a second hand axis while pulling up the hand by a push up member fixed at an eccentric position on the rotation axis. CONSTITUTION:A second hand 5 loosely fitted to a hand holding shaft 8 at the tip of second hand axis 2 usually hangs down at the position of six o'clock. When the front edge 4a of the second hand push up piece 4 on a second hand support 1 that rotates with the second hand axis 2 comes to the position of six o'clock under this condition, the suspending second hand 5 is pushed by this and pulled up to the position of twelve o'clock and drops again freely to the position of six o'clock. In the case where the angle occupied by the second hand push up piece 4 is sufficiently shorter than 180 deg., the hand oscillates around the point of six o'clock and damped slowly and stopped. Accordingly, when an airplanelike ornamental piece 6 is provided at the tip of the second hand 5, this ornamental piece 6 makes slow and quick motion at every 30sec and makes unique motion on the dial.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a timepiece in which a second hand has a special movement.

(Prior art) Clocks placed indoors, such as time clocks and wall clocks, are required to have decorative functions as furniture and furnishings in addition to their original timekeeping function. These watches have static or dynamic designs, such as elaborate designs on the case or a pseudo-pendulum similar to a perpetual clock.

However, conventional watches do not have wood-like decorations even on the time display surface, and despite the fact that they do not require time reading down to the second,
Since the hour, minute, and second hands are provided to display the time, the display surface, which occupies a large area, is separated from other parts in terms of design, and the watch as a whole does not necessarily have a sufficiently attractive product. I had an indescribable dislike.

(Purpose) The present invention has been made in view of the above circumstances, and its purpose is to make the entire surface of the watch appear by making a relatively fast-rotating pointer such as the second hand exhibit a special movement. To provide a new clock that can be used as a part of the furniture and be attractive to children by giving a dynamic decorative effect to the display surface that occupies a large proportion of the screen.

(Structure) Therefore, details of the present invention will be described below based on illustrated embodiments.

Fig. 1.2 shows an embodiment of the present invention, in which reference numeral 1 denotes a sleeve-shaped second hand support hakama fixed to the end of the second hand shaft 2; Flange 3 provided
A second hand push-up piece 4, which is slightly taller than the wall thickness of the second hand 5, is formed on the periphery of the flange 3 and extends upright within a range not exceeding half the circumference of the flange 3. The second hand 5, which is rotatably attached to the shaft portion 8 of the first presser 7, is held by the flange 3 and the fourth presser 7 by fitting the presser foot 7 therein. In Figure 1, group number 6 indicates a decorative piece provided at the tip of the second hand 5, 9 indicates a dividing shaft, 10 indicates an hour hand shaft, and 11 indicates a dial plate.

In the embodiment described above, the side presser shaft portion 8 at the tip of the second hand shaft 2
The second hand 5, which is loosely fitted into the second hand, is normally resting at the 6 o'clock position due to its own weight. In this state, when the front edge 4a of the second sword pushing piece 4 of the metal dust 1 supporting hakama 11- which rotates with the second hand shaft reaches the 6 o'clock position, the second hand 5 which is descending downward is pushed by this and becomes 12 o'clock. It is pulled up to the 6 o'clock position, and then falls freely to the 6 o'clock position again, and if the angle occupied by the second hand push-up piece 4 is sufficiently shorter than 180°, it will swing around the 6 o'clock position. , gradually attenuates and stops] 1-. Therefore, if an airplane-shaped decorative piece 6 is provided at the tip of the second hand 5 as shown in the figure, this decorative piece 6 will make a slow and sudden movement every 30 seconds, making a unique movement on the dial 111-.

In the embodiment shown in FIG. 3, the second pin 24 is eccentrically provided at the tip of the second support hakama 21, and
1, the second hand 25 is made of wire as thin as possible, and a decorative piece 26 in the shape of a doll or the like is swingably attached to the tip of the second hand 25. According to this method, the decorative piece 26 can be rotated slowly and rapidly while being swung every 30 seconds while the dial 11 is kept in the same posture.

The embodiment shown in FIG. 4 employs a well-known gear train mechanism in which gold dust 435 is disposed on the dial 38 side, and a sleeve 37 is slidably attached to the second hand 35 formed by a thin wire. The decorative piece 36 is suspended from this, and the decorative piece 36 is guided along a guide groove 39 provided on the dial 38. According to this embodiment, the decorative piece 36 is guided from the 6 o'clock position to the 12 o'clock position. By arranging the guiding groove 39 close to the second hand axis, the second hand pulling torque can be made as small as possible, and at the same time, the decorative piece 36 can be moved not only in the rotational direction but also in the radial direction. It can be made movable to make its movement more two-dimensional.

A further embodiment, shown in FIG.
It is formed as two arm bodies 45a and 45b, and decorative pieces 46a and 46b of approximately equal mass are suspended from the ends of each arm body, and these are alternately connected by a second hand push-up pin 44 that is eccentrically set up on the second button support hakama 41. According to this embodiment, by balancing the decorative pieces 46a and 46b provided at both ends, the torque when the second hand is pulled down to the left can be reduced as much as possible. Not only can you change the timing of raising the second hand from the 3 o'clock position to the 6 o'clock position and the 9 o'clock position.
It is possible to make the fluctuation even smaller by dividing the change twice from the hour position to the 122 o'clock position, and furthermore, when the second hand 45 freely falls, the appropriate sounding body contact piece 49 provided on the dial plate 48 can be Or by bringing it into contact with the decorative piece 46,
It is also possible to notify the current time every 15 seconds.

Although the present invention has been described above as an example of application to a second hand shaft, it is also possible to provide this type of finger ring on a rotating shaft whose rotational speed is faster than that of a weight and whose movement is visible. be.

(Effects) As described below, according to the present invention, a pointer with a decorative piece loosely fitted on a rotating shaft such as a seconds button shaft is pulled by a pusher member fixed at an eccentric position on the rotating shaft. - Since it is designed to drive while moving, the decorative piece provided there through the pointer performs two different types of interlocking movement: constant speed movement and falling movement due to its own weight, and the display occupies a large area of the watch surface. A special moving design can be applied to the movement of the face, and the watch can be given a decorative function as part of the furniture or a teaching tool for children, increasing its versatility.
