[Detailed description of the invention] Industrial application field This invention relates to a game board that is played by moving pieces along a path, and in particular, a game board in which a swinging member that is moved by a power means is installed in the middle of the path. It is related to.

BACKGROUND ART Japanese Patent Publications No. 40-3100 and Japanese Patent Publication No. 41-276 disclose a game board in which an operating member is attached. The former is equipped with a game board with a circumferential playing path that limits several stops and a mechanical device that operates, and is a game in which the pieces on the game board are captured, while the latter is a game that follows a rotating body competition. It is a game in which a plug needle is inserted into a competition board, and when the plug needle is inserted into a predetermined hole, an adjacent operating member such as a door is activated.

Purpose of the invention The present invention aims to provide a game board that is different in design from the game board in the conventional technology described above. This invention relates to a game board that can be swung by a button to obstruct the progress of pieces.

Means for Solving the Problems In order to achieve the above object, the game board according to this invention has a frame that forms the game board, in which a plurality of squares are formed in a ring shape at predetermined intervals. A swinging member having a plurality of squares formed thereon is disposed and rotatably supported, each of the squares is formed such that a piece on which an object is placed can be placed thereon, and the swinging member has a A notch is provided in each, an eccentric cam is engaged with the notch, a pinion is provided coaxially with the eccentric cam, and a ratchet wheel having a pinion that can be engaged with the pinion is rotated by a friction ring that rotates on a rotating shaft. A rotary lever with a bent end portion that engages with the ratchet wheel, and a ratchet wheel that has a missing pawl portion that engages and disengages with the pawl of the rotary lever are rotatably pivoted to the mechanical box. At the same time, a power mechanism for rotating the rotating shaft by operating a push button is provided in the mechanical box.

Function With this configuration, the swinging member shakes while the pieces are moving along the path, causing the pieces to fall off the path, or other objects placed on top of the pieces to fall, causing problems in the game. The power increases.

Embodiment What is shown in FIG. 1 is a perspective view of a game board 1 according to this invention.

This game board 2 includes a frame 6 whose upper surface is roughly shaped like a rocky mountain, and four rocky mountain-shaped squares 6a are formed near the outer periphery as a starting point or course for the pieces 4 to proceed, and a frame 6 in the middle of the course. A plurality of swinging members 8 are installed in the frame body 6, and each rocking member 8 has four rocky mountain-shaped squares 8a formed in a step-like manner as a path for the pieces 4 to move. It consists of a push button 10 that is randomly selected and activated via an installed power mechanism (see FIG. 2), and an animal object 12 whose mouth opens and closes when the push button 10 is pressed. An egg-shaped object 14 is placed on the frame 6 near the frame 12 .

The game board 2 of this embodiment can be played, for example, in the following manner.

It is preferable that there be four players, who take turns rolling the dice (not shown) and selecting the square 6 of the number rolled.
Move piece 4 counterclockwise by distances a and 8a, respectively, using the square 6a on your side as the starting point. and,
When your piece 4 lands on a predetermined square 8a (for example, a square with a purple label),
An egg-shaped object 14 can be placed on top of the pieces 4. Furthermore, by rolling the dice 16 several times to advance the piece 4, when the piece 4 rotates around and returns to its original position (starting point position), the egg-shaped object 14 can be obtained, and the obtained The object 14 is accommodated in a concave portion 6b formed in the projecting portion of the frame 6.

Note that when the piece 4 stops on a specific square 8a (for example, a square with a green label) during the game, the push button 10 must be pressed.
Then, when this push button 10 is pressed, one of the swinging members 8 swings, and unfortunately, the piece 4 with the egg-shaped object 14 placed on its head lands on the swinging member 8. When the piece 4 is placed thereon, due to its swing, the egg-shaped object 14 placed on it falls together with the piece 4, or only the egg-shaped object 14 falls. In this way, when the egg-shaped object 14 falls, it is returned to its original position. In this case, roll the dice (not shown) and get 4 pieces.
When the piece 8a again stops on the predetermined square 8a (the square with the purple label), the egg-shaped object 14 is placed on the head of the piece 4.

In the end, the person who obtains the most egg-shaped objects 14 wins.

Next, each component of the game board 2 will be explained in more detail.

As shown in FIG. 2, the frame body 6 is formed as a thin frame-shaped cover with an open bottom, and has four “dog”-shaped openings 6c at the four corners of the upper side, and one opening 6c near the center. One circular opening 6d and one relatively large opening 6e are formed in the vicinity of the circular opening 6d.

The swinging member 8 is formed in the shape of a thin frame, and a substantially flat plate-like flat part 8b extends in a rectangular shape at the lower peripheral edge of the swinging member 8, and a corner part near the outer end of the flat part 8b has a rectangular shape. A shaft 8c is provided vertically in each case, and a notch 8d is formed at each corner near the inner end of the same plane portion 8b on a diagonal line of the shaft 8c.

The rocky mountain-shaped central portions of these rocking members 8 are arranged to protrude upward from the opening 6c of the frame 6, and each shaft 8c is a bottom plate that closes the lower end opening of the frame 6. 18 (screw 2
0 to the lower end of the frame 6. )
It is rotatably fitted into shaft holes 18a provided at the four corners of. Screws 20 for fixing the four corners of the bottom plate 18 to the lower end of the frame 6 are screwed into the lower end of the frame 6 through holes 8d of the shaft 8c fitted in the shaft hole 18a.

A power mechanism for swinging these swinging members 8 will be described later.

The animal object 12 is attached by screws 22 onto a mechanical box 24 installed in the frame 6, and is arranged to protrude upward through the through hole 6e of the frame 6. This animal body 12 has a body part 1
It has an upper jaw part 12b that can be opened and closed with respect to a lower jaw part 12c of 2a.

Next, a power mechanism for opening and closing the mouth of the swinging member 8 and the animal object 12 will be explained.

The power mechanism is housed in a hollow mechanical box 24 formed by integrating an upper frame 26 and a lower frame 28.

As shown in Fig. 3, a tension spring 3 serves as a power source.
0 is guided in an L-shape, and a sliding member 32 is provided which is given a return force in the direction A in FIG. 3 by this tension spring 30.

As shown in the third figure, when the push button 10 is pushed down, the rotating lever 36 supported by the bearing plates 28a, 28a of the lower frame 28 moves counterclockwise by the pin 34, and is interlocked with this. It is designed to be moved in the direction of arrow B.

That is, the pushbutton 10 is supported so as to be able to rise and fall freely on a pillar 28b erected at a corner inside the mechanical box 24, and its upper end is inserted through the cylindrical hole 26c of the upper frame 26 and the opening 6d of the frame 6. It protrudes upward. A projecting piece 10a is integrally provided on the lower side of the push button 10 located inside the mechanical box 24. There is. Also, the lower back side of the rotating lever 36 (in Fig. 3)
A pin 36b is provided protruding toward the front side of the sliding member 32 through a long hole 28c formed in an arc shape in the bearing plate 28a on the back side. 32a.
The pins 34, 36a, and 36b are arranged to form a triangle when these three are connected with a straight line.

On the other hand, a protrusion 3 is provided on the back side of the upper part of the sliding member 32.
2b is provided substantially horizontally, and 32c is formed in the middle thereof.

An eccentric pin 38a of a cam disc 38 rotatably disposed in the mechanical box 24 is fitted into the notch 32c. This cam disk 38 is connected to the rotating shaft 40 by the rotating shaft 40.
0, and a gear 4 is located below the cam disk 38 of the rotating shaft 40.
2 is fixed (axially mounted). The gear 42 and the cam disk 38 are connected to each other by a one-way clutch 44 fixed (axially attached) to the upper side of the gear 42, so that the sliding member 32 is moved in the direction A in FIG. When the cam disk 38 rotates clockwise in the figure, they rotate together, and when the sliding member 32 rotates in the direction B, that is, when the cam disk 38 rotates counterclockwise, only the cam disk 38 rotates (idly rotates). It is related as follows.

Also, a rotating shaft 4 located below the gear 42
A ratchet wheel 46 is fixed to the 0 portion (FIG. 2).
As shown in FIG. 4, this ratchet wheel 46 has teeth at every 30 degrees, with one tooth missing, for a total of 11 teeth. A rotating lever 48 having a pawl 48a on the inner end side is installed near the ratchet wheel 46 and is applied with rotational force in the clockwise direction in FIG. 2 by a spring 50. The pawl 48a engages with the pawl of the ratchet wheel 46. The inner end of the rotating lever 48 passes through the opening 28d of the lower frame 28, reaches below the lower frame 28, and engages with a pawl of a ratchet wheel 72, which will be described later.

Further, a lower gear 54a of a two-stage gear 54, which is formed by two gears fixed to the same rotating shaft 52, meshes with the gear 42, and an upper gear 54b is connected to a pinion gear body adjacent to the gear 54a. 56 (A pinion 56a and a gear 56b are fixed to the same rotating shaft.)
The gear 56b meshes with the pinion 60a of a pinion/gear body 60 (the pinion 60a and the gear 60b are fixed to the same rotating shaft 62) located adjacent to the pinion 60b. is the pinion 66 of the speed governor mechanism 65
It meshes with.

A half-moon key 54c is fixed to the upper end of the rotating shaft 52 to which the two-stage gear 54 is fixed. This half-moon key 54c is connected to a center hole 64a of a cam body 64 rotatably installed on the upper frame 26 of the mechanical box 24.
The cam body 64 is fitted into the cam body 64, transmits rotational force to the cam body 64, and rotates together with the cam body 64.

On the other hand, a cylindrical body 26a having a vertically elongated slit hole 26b on the cam body 64 side is protruded from a position near the cam body 64 on the upper frame 26. A shaft rod 66 is housed in this cylindrical body 26a so as to be able to rise and fall freely, and a projecting piece 66a formed on the side of the shaft rod 66 extends outward through a slit hole 26b. The lower end of the projecting piece 66a is placed in contact with a cylindrical upwardly facing pawl 64b of the cam body 64 (the rotational direction side of the pawl 64b is inclined and the rear side is vertical). ing.

Therefore, when the cam body 64 rotates counterclockwise in FIG. 2, the shaft rod 66 moves up and down. The upper end of this shaft 66 passes through a through hole 12d provided in the lower jaw part 12c on the body 12a side of the animal body 12 attached to the upper frame 26, so that the upper jaw 12b connects to the lower jaw 1.
It abuts on the lower side of the upper jaw 12b on the front side of the portion rotatably supported by the upper jaw 2a. As the shaft 66 moves up and down, the upper jaw 12b moves.

On the other hand, the lower end side of the rotating shaft 62 to which the pinion gear body 60 is fixed passes through the lower frame 28 and reaches below it, and the gear 68 is fixed to the lower end side.

The central portion of this gear 68 bulges upward, and the lower side thereof is a concave portion (not shown). A coil spring 70 is elastically mounted in this concave portion and is fitted onto the rotating shaft 62.
A ratchet wheel 72 is loosely fitted onto the rotating shaft 62 so that the gear 68 is pushed up from below and gently slides into contact with the lower surface of the gear 68. This ratchet wheel 72 has a total of 8 pawls arranged at 45 degrees.
As mentioned above, the bent end portion 4 of the rotating lever 48
8b is engaged. Further, the lower surface of the ratchet wheel 72 is pressed against the upper surface of a friction ring 74 which rotates together with the rotary shaft 62 at the lowermost position of the rotary shaft 62 by a coil spring 70 with a relatively weak force.

Further, two pinions 76 are pivotally supported on the ratchet wheel 72 at a center angle of 135 degrees from each other and are always in mesh with the gear 68. These two pinions 76
The positions coincide with the front end positions of the claws of the ratchet wheel 72, respectively.

On the other hand, on the lower side of the mechanical box lower frame 28, pinions 78 that can mesh with the outer end teeth of the pinions 76, 76 are rotatably installed in a concentric arrangement with a pitch of 90 degrees. An eccentric cam 80 is integrally provided above the pitch 78.

These eccentric cams 80 each have the swinging member 8
It is arranged in the notch 8d of.

Furthermore, the piece 4 is shaped like a doll with its hand raised, so that the egg-shaped object 14 can be placed exactly on top of the raised hand.

Next, the operation of the game board 2 of the embodiment configured as above will be explained.

First, when the push button 10 is pressed down to the lowest position, the sliding member 32 moves in the direction of arrow B in FIG. 3 via the rotating lever 36, and the tension spring 30 extends, as described above. Tensile energy is stored in the tension spring 30.

During this time, the cam disk 38 is rotated counterclockwise as viewed from above in FIG. only rotates,
The members below gear 42 do not move.

After that, if the push button 10 is released,
The sliding member 32 returns in the direction of arrow A (in FIG. 2) due to the tensile force of the tension spring 30, and the push button 10 returns to its original position.

As the sliding member 32 returns in the direction of arrow A, the cam disk 38 rotates clockwise in FIG. 3.

At this time, the cam disk 38 and the gear 42 are coupled to each other by the one-way clutch 44, and the gear 42 rotates together with the cam disk 38 in the clockwise direction shown in the second figure.

As the gear 42 rotates, the two-stage gear 54, pinion gear 56, and pinion gear body 60, which are in mesh with each other in sequence, rotate, but are controlled at a relatively low speed by the operation of the governor 65.

As the two-stage gear 54 rotates, the cam body 6
4 and the shaft 66 move, thereby causing the animal body 1 to move.
2's upper jaw 12b moves rapidly.

On the other hand, when the push button 10 is fully pushed down and released, the ratchet wheel 46 that moves together with the gear body 42 moves two pitches clockwise in FIG. 2 (counterclockwise in FIGS. 4A and B). It rotates (the gear ratio etc. are determined in this way). This ratchet wheel 46 is 2
During the rotation of the pitch pawl, the pawl of the ratchet wheel 46 hits the pawl 48a of the rotary lever 48 twice, so the rotary lever 48 moves counterclockwise in FIG. 2 against the force of the spring 50. The operation of rotating clockwise (clockwise in FIGS. 4A and 4B) and returning clockwise (counterclockwise in FIGS. 4A and B) is repeated twice.

Then, the pawl of the pawl wheel 46 is connected to the pawl 4 of the rotating lever 48.
8a and the rotating lever 48 rotates in the counterclockwise direction in FIG.
The lock of the pawl 2 is released (FIG. 4B). At this time, the ratchet wheel 72, which is weakly pressed against the friction ring 74 by the coil spring 70, comes into frictional contact with the friction ring 74 rotating together with the rotating shaft 62 in a counterclockwise direction (as shown in FIGS. 4A and 4B). rotates clockwise). This rotation speed varies depending on how the push button 10 is released and is not constant.

After that, the claw 48a of the rotating lever 48 comes out of contact with the claw of the ratchet wheel 46, and the rotating lever 48 rotates clockwise in FIG. 2 (counterclockwise in FIGS. 4A and B). The rotation lever 48 returns to its original position.
The pawl 48a of the ratchet wheel 46 engages with the pawl of the ratchet wheel 46 again (the fourth
Shown in Figure A. ), the tip bent portion 48b of the rotating lever 48 also returns to its original position and engages with the pawl of the ratchet wheel 72 (as shown in FIG. 4A), and at this point the ratchet wheel 72 stops rotating. .

The rotation angle of the ratchet wheel 72 during this period varies depending on how the push button 10 is released and is not constant. In other words, the rotation angle of the ratchet wheel 72 has randomness.

When the ratchet wheel 72 stops, one of the pinions 76 meshes with one of the pinions 78. At this time, the other pinions 76 and 78 are in a free state.

The pinion 78 meshed in this way is rotated by the rotational force of the gear 68 being transmitted from the pinion 76 . One of the swinging members 8 is swung by the eccentric cam 80 that rotates together with the pinion 78 .

When the push button 10 is operated once, the ratchet wheel 46 moves two times.
The rotating member 8 rotates by a pitch, and as a result, any two swinging members 8 swing one by one after a short period of time.

However, the missing pawl portion of the ratchet wheel 46 is connected to the rotary lever 4.
8, even if the ratchet wheel 46 rotates by two pitches with one operation of the push button 10, one pawl is missing and only one pawl remains on the rotating lever 48. Since it does not hit the claw 48a, the rotating lever 48 rotates only once, and therefore the swinging member 8 also swings only once.

Due to these various factors, it is impossible to predict which swinging member 8 will swing.

If the piece 4 with the egg-shaped object 14 placed on its hand is unfortunately placed on the square 8a of the swinging member 8 that swings as described above, only the egg-shaped object 14 or the egg-shaped The object 14 and the pieces 4 fall.

Effects of the invention The game board according to this invention uses squares arranged in an annular shape as the course, advances the pieces according to the results of the dice, etc., and operates the power mechanism by operating the push button. When one of the swinging members swings, the pieces fall off the path, or objects placed on the pieces fall, increasing the power and thrill of the game and making it hard to get bored.
