Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a game clock used in games such as Go, Shogi, Chess, etc., which are played with a time limit.

[Prior Art] Traditionally, game clocks include a seesaw-shaped switch lever that is swung by alternately pressing a pair of push buttons, and a pair of seesaw-shaped switch levers that are alternately opened and closed by the oscillation of the switch levers. It was equipped with a switch and two clock movements that were alternately driven and stopped by opening and closing the switch.

Then, the time allowed for the game is set in each clock in advance, and the switch lever is set in the horizontal position, that is, the neutral state, just before the game starts, and at the same time as the game starts, the player in the last position presses the push button, and the switch lever is set in the neutral state. is clicked, and the first player's clock starts operating and starts moving its hands. When the first player presses a push button after making one move, this state is clicked, the first player's clock stops, and at the same time the second player's clock starts operating and starts moving. As the player presses his or her own button in this way, the time available to the other player decreases.

[Problem to be Solved] As described above, it is necessary for the switch lever to be clicked in both the pushed up state and the pushed down state, but the problem is maintaining the position in the neutral state. Although it is natural that it would be difficult to maintain the neutral position without a click at all, it was found that when a click was provided, there was a risk that the switch lever could not be pressed down smoothly at the start of a match. did.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a game clock that can smoothly press down a seesaw-type switch lever at the start of a game.

[Means for Solving the Problems] The present invention is characterized by a click plate having a convex portion in the center opposite to both ends of a seesaw-type switch lever that is swung by pressing a push button. Both ends of the spring are fixedly supported, and both ends of the switch lever have a first recess that engages with the convex part when the switch lever is in the pushed-up state, and a first recess that engages with the protrusion when the switch lever is in the pushed up state. a second recess that engages with the projection when the switch lever is in the depressed state; a flat surface that is located between the first and second recesses and that the projection contacts elastically when the switch lever is in the neutral state; It is located where it is located.

[Examples] Examples of the present invention will be described below based on the drawings.

In Fig. 1, two clocks 2 and 2a for both players are installed on the front of the frame 1, and a pair of clocks 2 and 2a are placed on the top of each clock protruding from the top surface of the frame. Push buttons 3, 3a are provided, which are depressed alternately by the players. As shown in the second diagram, two crystal movements 4, 4a are arranged on the back of each timepiece 2, 2a. Drive current is alternately supplied to each movement 4, 4a from a battery 5 set in the movement case via micro switches 7, 7a, so that the movements are alternately driven. It's summery. The movements 4, 4a have needle turning knobs 6, 6a.
is provided.

The contact pieces 8, 8a of each micro switch 7, 7a are provided with both ends 91 of a seesaw type switch lever 9,
The lower surface of 91a is movable.

The switch lever 9 is pivotally supported by a shaft 10, and the switch lever 9 is supported by a shaft 10.
It is swung by pressing down on one of the pair of push buttons 3, 3a.

When the switch lever 9 is in a horizontal state, that is, in a neutral state, both ends 91, 91a are not in contact with both end pieces 8, 8a of the microswitches 7, 7a, and both microswitches are in the off state.

As shown in the second figure, when the switch lever 9 is in the state of being lowered to the right, one contact piece 8a is pressed down and the other contact piece 8 is not pressed down, so that one micro switch 7a is pressed down. is on, and the other micro switch 7 is off. Therefore, as shown in FIG. 4, one timepiece movement 4a is supplied with current and is in an operating state, but the other timepiece movement 4 is not supplied with current and is in an inoperative state.

Further, as shown in the third figure, adjustment members 12, 12a are integrally formed and protruded from both ends of the switch lever 9. On the other hand, both ends of click leaf springs 14, 14a that engage with the adjustment members 12, 12a are fixedly attached to the clamping bodies 13, 13a formed on the frame 1. The center portions of the click leaf springs 14, 14a are formed with convex portions that protrude toward the adjustment member 12.

To explain the shape of the outer edge of the degree determining members 12, 12a, the central part of this side is a flat part 15a, and this flat surface is vertically straight and forms a degree determining part in a neutral state. This is when the switch lever 9 is in the horizontal position.
That is, when in the neutral state, it comes into elastic contact with the convex portion of the click leaf spring 14 and maintains that state. Since both ends of the click leaf springs 14, 14 are held fixedly, the spring pressure of these springs is increased.

On the flat part 15a for determining the neutral position, a second groove-shaped recess 15b for determining the pressing position is connected.
In the figure, the switch lever 9 is lowered on the left shoulder.
In other words, when in the depressed state, the click leaf spring 14
The switch lever is engaged with the convex portion of the switch lever to click the tilted state of the switch lever.

Furthermore, below the neutral positioning portion 15a, there is a first recess 15c for clicking at the depressed position.
are connected to each other, and when the left shoulder of the switch lever 9 is in an up position, that is, in a pushed-up state as shown in the third figure, it engages with the convex part of the click leaf spring 14, causing the switch lever to tilt. Click on the status.

Therefore, both ends 91, 91a of the switch lever 9
The contact pieces 8, 8a of the switches 7, 7a are kept pressed down or released.

Next, how to use the present invention will be explained.

First of all, the state before the start of the match is to press both buttons 3, 3.
At least one of the switch levers 9a is pushed down lightly to the neutral position, and the switch lever 9 is positioned horizontally, with both ends 91 and 91a not pushing down the contact pieces 8 and 8a. At this time, both microswitches 7, 7a shown in FIG. 4 are in an OFF state, and both timepiece movements 4, 4a do not operate. Positioning in this state is performed by the positioning member 12,
Flat part 15a of 12a and click leaf spring 14,1
This is done by engagement with the convex portion of 4a.

Then, the time allowed for the game is set using the hand turning knobs 6 and 6a. For example, in a shogi game, you have two hours to play, so set the hands at 10 o'clock so that when two hours have passed it will be exactly 12 o'clock.

Then, at the same time as the signal to start the game, the second player presses down the push button 3, for example, and the switch lever 9 goes down to the right as shown in the second figure, and one of the micro switches 7 turns off. , the other micro switch 7a is turned on, and therefore the movement 4 does not operate, and only the first movement 4a starts operating.

At this time, the first recess 1 of the degree determining member 12
5c is in elastic contact with the convex portion of the click leaf spring 14,
Maintain this position.

When the first player presses down the push button 3a after making one move, the micro switch 7a is turned off and the micro switch 7 is turned on, which causes the movement 4a to stop operating and the second movement 4 to start moving the hands. do.

At this time, the second recess 1 of the degree determining member 12
5b is in elastic contact with the convex portion of the click leaf spring 14,
Maintain this position.

Thereafter, each time a player makes a move, they alternately press the push buttons 3, 3a to activate the opponent's movement, and the remaining time gradually decreases, which is displayed on each clock 2, 2a.

[Effects] In the present invention having the above configuration, when the switch lever is in the neutral position, the convex portions of the click leaf spring held at both ends are in elastic contact with the flat portions at both ends of the switch lever, so that the switch lever is in the neutral position. Not only can the state be reliably maintained, but the switch lever can be swung by smoothly pressing the push button at the same time as the game starts, and the on/off state of the switch is controlled by the click leaf spring and the first switch lever. , and the second recess. Furthermore, since the configuration is simple when applying a click motion, manufacturing costs can be reduced, and the device can be attached at low cost.
