BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a railroad crossing machine according to an embodiment of the present invention.

The level crossing machine 1 has an approximately cross shape in plan view and includes an upper board 2 and a lower board 3 (see FIG. 2). Upper panel 2
As shown in FIG. 1, the vehicle has a road 5 on which a car toy 4 travels and a track 7 on which a train toy (see FIG. 4) 6 travels. I have. In addition, a railroad crossing 8
A movable trajectory 9 is provided, the tip of which is opposed to the trajectory and is moved downward by the weight of the train toy 6 which is urged upward and passes therethrough. On the other hand, on the left side of the roadway 5 before the level crossing 8,
A circuit breaker 10 that blocks the road 5 when the train toy 6 passes through the railroad crossing 8 is provided. A push button 11 is provided on the right side of the road 5.

On the road 5, first and second stoppers 15, 16 for stopping the toy by contacting the tip of the toy 4 are arranged in order toward the railroad crossing 8. The first and second roller portions 17 for idling the four drive wheels (the rear wheels in this embodiment) 4a,
18 are arranged in order toward the railroad crossing 8.

In the railroad crossing machine 1, when the toy car 4 running on the road 5 approaches the railroad crossing 8, the leading end of the toy car 4 comes into contact with the first stopper 15 protruding from the roadway 5, so that the toy car 4 4 is temporarily stopped. In this state, when the train toy 6 approaches the railroad crossing 8, the movable track 9 moves down, and accordingly, the circuit breaker 10 descends, and the first stopper 15 descends below the roadway 5, and the second stopper 16 project. As a result, the automobile toy 4 is reliably started without disengaging from the first stopper and slipping on the roller portion 17, and is stopped again by contacting the second stopper 16. When the train toy 6 passes through the railroad crossing 8 in this state, the movable track 9 returns (moves upward).
The stopper 16 sinks below the road 5 and the first stopper 15
Protrudes. Thereby, the automobile toy 4 is released from the engagement with the second stopper 16 and starts without slipping on the second roller portion 18, and crosses the railroad crossing 8. When the train toy 6 is located far away from the railroad crossing 8, the operation of the push button 11 forcibly pushes down the first stopper 15 to disengage the first stopper 15 from the vehicle. The toy 4 can be run. Although it looks phenomenally the same as the prior art, the embodiment is different from the prior art in that when the car toy 4 starts after stopping, the roller portions 17 and 18 in contact with the car toy 4 are automatically locked. It is very different.

Next, the construction of the railroad crossing machine 1 will be described with reference to FIGS.
This will be described in detail with reference to FIG. In this embodiment,
Since the railroad crossing machine 1 is symmetrical with respect to the railroad crossing 8, some of the components are not shown in FIG.
Hereinafter, only one side will be mainly described.

The roadway 5 is formed in a groove shape on the upper panel 2 and can be extended by connecting roadway parts (not shown) via a connecting portion 5a. On the other hand, the track 7 is formed in a groove shape on the upper platen 2 and can be extended by connecting track parts (not shown) through the notch 7a.

As shown in FIG. 2, the movable track 9 is mounted on the upper plate 2 so as to be rotatable about a shaft 21 provided at a base end thereof. ) Is urged upward. The movable track 9 moves downward by the weight of the passing train toy 6. An engagement plate 22 is provided at each of the distal ends of the two movable tracks 9, and the two engagement plates 22 are engaged with the other engagement plates 22.
It is designed to move downward and upward integrally. That is,
First and second engagement protrusions 23 and 24 are formed on the engagement plate 22.
Are mounted on the other second engagement projections 24 so that they are combined with each other. When one movable track 9 moves down or moves up, the other movable track 9 also moves down or moves up. The engagement plate 22 is sunk below the railroad crossing 8 and is not visible from the outside.

The circuit breaker 10 includes a breaking arm 31, a balancer 32 bolted to a base end of the breaking arm 31,
The balancer 32 includes a weight 34 housed in a weight case 33 formed on the balancer 32 and a link member 35 for engaging with the blocking arm 31 to move the blocking arm 31 downward. The circuit breaker 10 is rotatably supported by a bearing 27 erected on the railroad crossing machine 1 by a shaft 36 attached to the balancer 32. In addition, the link member 35 has a shaft hole 38 at the base end protruding from the side of the movable track 9.
And the claw 39 at the tip is in contact with the upper side of the blocking arm 31. Accordingly, the downward movement of the movable track 9 causes the claw 39 of the link member 35 to push down the blocking arm 31 and the blocking arm 31 is swung down. on the other hand,
When the movable track 9 moves upward, the link member 35 returns to the original position, and the blocking arm 31 is swung up by the weight of the weight 34 of the balancer 32 and returns to the original state.

The first stopper 15 is, as shown in FIG.
It is composed of a planar inverted L-shaped arm plate. The first stopper 15 is rotatably supported by a bearing 42 erected on the lower platen 3 at a portion of a shaft 41 provided at a base end portion. The pivotal support position of the first stopper 15 is on the far side of the track 7. A locking portion 43 protruding upward is attached to the distal end of the first stopper 15.
3 is an opening 13 provided in front of the level crossing 8 of the road 5.
Is facing. First stopper 15 configured as above
The locking portion 43 is opened by the spring 77 described later.
It is urged in the direction to protrude from. On the other hand, the projecting piece 45 attached to the side of the first stopper 15 has a movable track 9.
The lower engaging projection (see FIG. 3) 44 can abut, and the first stopper 15
Is depressed so that the locking portion 43 sinks with respect to the road 5.

The second stopper 16 is formed of a seesaw member capable of seesaw movement, and a shaft 51 provided at an intermediate portion thereof is rotatably supported by a bearing 53 erected on the lower platen 3. ing. The pivotal support position of the second stopper 16 is on the near side of the track 7. A locking portion 53 protruding upward is attached to the front end of the second stopper 16 on the near side, and the locking portion 53 is provided at an opening provided on the front side of the level crossing 8 of the roadway 5. We are facing 12. The second stopper 16 configured as described above is engaged with the engagement pin 55 (see FIG. 3) of the movable track 9 by a notch 54 provided at the distal end on the far side. Therefore, the locking portion 53 of the second stopper 16 projects into the opening 13 due to the downward movement of the movable track 9. The start of the operation of projecting the second stopper 16 is performed earlier than the start of the operation of sinking the first stopper 15. This timing shift is caused by the first stopper 1
This is caused by the presence of a gap between the projection 45 of the fifth member 5 and the engagement projection 44 of the movable track 9. With this configuration, even when the distance between the first stopper 15 and the second stopper 16 is not sufficient, the second stopper 16 can be operated earlier than the first stopper 15. The vehicle stopper 4 can be reliably stopped by the second stopper 16.

The first and second roller portions 17 and 18 are a pair of roller members 6 each having two left and right rollers 62 and 62 and a pinion 63 mounted on a roller shaft 61, respectively.
4 sets are provided. Each roller member 64 is connected to each roller 6.
2 is an opening 14 provided in front of the level crossing 8 of the roadway 5.
And the roller 62 is supported by a roller bearing 65 erected on the lower plate 3 such that the uppermost part of each roller 62 is flush with the road surface.

Next, first and second lock members 71 and 81 for locking the first and second roller portions 17 and 18 will be described.

The first lock member 71 is constituted by a seesaw member capable of seesaw movement, and a shaft 72 provided at an intermediate portion thereof is rotatably supported by a bearing 73 erected on the lower platen 3. Have been. The pivot position of the first lock member 71 is below the second roller portion 18. Also, three (for example, rubber) locking portions 74 protruding upward are attached to the front end portion of the first locking member 71 on the near side,
Each locking portion 74 can mesh with a corresponding pinion 63 in the first roller portion 17. The rear end of the first lock member 71 configured as described above is sunk below the front end of the first stopper 15, and the first lock member 71 is fixed to each locking portion by a spring 77. 74 is biased in a direction to separate the pinion 74 from the corresponding pinion 63. As a result, when the front side of the first stopper 15 moves downward due to the downward movement of the movable track 9, the front side of the first lock member 71 moves upward, and each locking portion 74 meshes with the corresponding pinion 63. As a result, the roller 62 is locked. In the normal state, the front end of the first stopper 15 is lifted by the rear end of the first lock member 71, and the first stopper 1
The fifth locking portion 43 is made to protrude from the opening 13.

The second lock member 81 is formed of a crank-shaped seesaw member, and has a shaft 82 provided at an intermediate portion thereof.
Are rotatably supported by bearings 83 erected on the lower platen 3. The pivot position of the second lock member 81 is slightly closer to the front end of the first stopper 15. At the front end of the second lock member 81, three (for example, rubber) locking portions 84 protruding upward are attached, and each locking portion 84 is a second roller. The corresponding pinion 63 in the portion 18 can be engaged. The second lock member 81 thus configured is engaged with the locking pin 86 at the front end of the second stopper 16 by the notch 85 at the rear end. As a result, when the front side of the second stopper 16 moves upward due to the downward movement of the movable track 9,
The front side of the second lock member 81 is moved downward, each locking portion 84 is separated from the corresponding pinion 63, and the roller 62 is unlocked.

Further, the push button 11 is connected to the first stopper 1
5 is provided with a protruding piece 11 a for pushing down, and is urged upward by a spring 90.

Next, the operation of the railroad crossing machine 1 will be described with reference to FIGS.
This will be described with reference to FIG.

FIG. 3 is a side sectional view of the railroad crossing machine 1 in a normal state. As shown in the drawing, in a normal state, the locking portion 43 of the first stopper 15 protrudes from the roadway 5 as a result of the first lock member 71 being biased by the spring 77, and the locking portion 74
Have the roller 62 in the unlocked state. Further, as a result of the movable track 9 being urged upward, the second stopper 16
The locking portion 53 of the second lock member 81 is in contact with the locking portion 53 of the second roller portion 18.
Is locked. When the vehicle toy 4 travels in this state, the front wheel of the vehicle toy 4 rides over the first and second roller portions 17 and 18, and the front surface of the vehicle toy 4 comes to the locking portion 43 of the first stopper 15. The abutment ensures that the automobile toy 4 is stopped. FIG. 3 shows the state when the vehicle is stopped (the roller 62 is not shown). In this state, the rear wheel 4 a of the automobile toy 4 rides on the unlocked first roller unit 17. Because it is, it is idling. Therefore, there is no overload on the motor.

Next, when the train toy 6 enters the railroad crossing 8, the movable track 9 starts moving downward due to the weight of the train toy 6. In this case, the link between the shaft 55 of the movable track 9 and the notch 54 of the second stopper 16 causes the second stopper 16 to immediately start the seesaw motion, and the locking portion 53 projects from the roadway 5. On the other hand, the engagement protrusion 44 of the movable track 9 comes into contact with the locking portion 45 of the first stopper 15 and is pushed down slightly after the seesaw movement of the second stopper 16.
The locking portion 43 is submerged in the road 5.

Further, one end of the second lock member 81 on the side of the notch 85 is lifted by the seesaw movement of the second stopper 16, so that the second lock member 81 also performs the seesaw movement, and the locking portion 84 is moved by the second roller. The roller 62 of the section 18 is unlocked. Further, the seesaw movement of the first stopper 15 lowers one end of the first stopper 15 on the locking portion 43 side, and pushes down the first lock member 71. As a result, the first lock member 71 also performs the seesaw movement and locks. The part 74 is the first
The roller 62 of the roller unit 17 is locked. As a result, the car toy 4 starts to run, but the car toy 4 is reliably stopped by the second stopper 16 because the second stopper 16 has already protruded before moving forward. In the stopped state, the rear wheel 4a of the automobile toy 4
Is idled by the rollers 62 of the second roller section 18, so that the motor is not overloaded. FIG. 3 shows this stopped state (the roller 62 is not shown).

Next, when the train toy 6 passes through the railroad crossing 8, the movable track 9 is moved upward by the urging means, and the shaft 55 of the movable track 9 pushes up one end of the second stopper 16 on the side of the notch 54, whereby The second stopper 16 also immediately starts the seesaw motion, the locking portion 53 sinks into the roadway 5, the second lock member 81 also performs the seesaw motion, and the locking portion 84 of the second lock member 81 moves to the second roller portion. The 18 roller 62 is locked. At the same time, since the first stopper 15 is disengaged from the movable track 9, the first lock member 71
The seesaw motion is performed by the urging force of the spring 77, and the locking portion 7
4 releases the lock of the roller 62 of the first roller unit 17. At the same time, the first stopper 15 also rotates, and the locking portion 4
3 protrudes into the road 5. Thereby, the automobile toy 4 reliably starts running. In this case, the first stopper 15 also returns and the locking portion 43 comes into contact with the vehicle bottom of the automobile toy 4, but since the urging force of the spring 77 is weak, there is no force enough to lift the automobile toy 4, The automobile toy 4 crosses the railroad crossing 8 while rubbing the locking portion 43 of the first stopper 15 with the vehicle bottom of the toy 4.

When the train toy 6 does not pass through the railroad crossing 8, the automobile toy 4 crosses the railroad crossing 8 by pressing the push button 11. When the push button 11 is pressed, the protruding piece 11a of the push button 11 pushes down the first stopper 15, and the first stopper 15 is rotated downward independently of the movable track 9, so that the locking portion 43 is moved to the roadway. Dive into 5. At the same time, the first lock member 71 also performs a seesaw motion, and the locking portion 74 locks the roller 62 of the first roller portion 17. In this case, since the movable track 9 does not move downward, the second stopper 16 and the second lock member 81 maintain the previous state, and as a result, the first and second stoppers 15, 1
6, the two locking portions 43, 53 sink into the roadway 5, and the first,
The two rollers 62,... Of the second roller portions 17, 18 are locked, and the automobile toy 4 starts running and crosses the railroad crossing 8.

As described above, according to the present embodiment, under normal conditions, the first roller portion 17 is in the unlocked state and the first stopper 15 protrudes into the roadway 5, so that the vehicle toy 4 Is stopped before the railroad crossing 8 without fail, and apparently travels while observing traffic regulations. In the stopped state, the driving wheel 4a of the automobile toy 4 is idled by the first roller portion 17, so that the motor is not overloaded. Furthermore, when the train toy 6 passes through the railroad crossing 8, the first roller portion 17 is locked by the downward movement of the movable track 9, so that the automobile toy 4 can start without slipping. Also, when the train toy 6 passes through the railroad crossing 8,
Since the second roller portion 18 is locked by the upward movement of the movable track 9, the car toy 4 can similarly start without slipping.

In the above embodiment, the case where the train toy 6 is driven by the rear wheels has been described. In this case, the distance between the first roller portion 17 and the second roller portion 18 is increased, and the locking portion 43 of the first stopper 15 is interposed therebetween.
May be configured to protrude.

The connection relationship between the movable track 9 and the first and second stoppers 15, 16 and the first and second lock members 71, 81 is not limited to the present embodiment, but is within the scope of the present invention. Changes can be made within

[0037]

As described above, according to the railroad crossing machine of the present invention, the first lock member unlocks the first roller portion in the normal state and locks the movable roller by the downward movement of the movable track.
Since the second roller portion is provided with the second lock portion that locks in the normal state and unlocks the movable roller when the movable track is moved downward, the automobile toy can be reliably stopped just before the railroad crossing and can be reliably started. .
