Description

[Detailed description of the invention] The present invention relates to a device for measuring the running time of a running toy.In particular, the time counting starts at the same time as the running toy starts running, and when the running toy collides with an obstacle and suddenly stops, its inertia This invention relates to a device in which time counting is stopped by . Furthermore, the device according to the present invention uses the rotational force of the flywheel, which is the drive source of the traveling toy, to count the time, and is designed to obtain an average time count even when traveling at high speed.

An embodiment of the present invention will be described based on the drawings.
The chassis 1 is provided with machine frames 2a, 2b, and 2c, and a flywheel 3 serving as a drive source is pivotally supported on the machine frames 2b, 2c, and 2a. A drive gear 4 is fixed on the spindle of the flywheel 3, and the drive gear 4 is always in mesh with a large-diameter intermediate gear 5a, and a small-diameter intermediate gear 5b is connected to the intermediate gear 5a.
are integrated. Idle gear 9a, 9
The support shaft 7 of b is loosely fitted into long holes 8a and 8b bored in the machine frames 2a and 2b, and when pushed up to the upper ends of the long holes 8a and 8b by the wire spring 11, the large diameter idler The gear 9a meshes with the small-diameter intermediate gear 5b, but when the wire spring 11 is pushed down, the support shaft 7 descends inside the elongated holes 8a and 8b, and the meshing between the large-diameter idle gear 9a and the small-diameter intermediate gear 5b stops. It will be canceled. The large diameter idle gear 9a is the small diameter idle gear 9
It has b integrally.

The support shaft 12 of the large-diameter idle gear 14a is connected to the machine frame 2.
It is loosely fitted into the long holes 13a, 13b bored in the holes 13a, 2b, and the wire spring 11 is inserted into the long holes 13a, 13b.
When the large diameter idle gear 14a is pushed up to the upper end of the axle 16, the large diameter idle gear 14a is in mesh with the drive gear 4, but the small diameter idle gear 14b provided integrally with the large diameter idle gear 14a is When the rotation of the axle gear 17a in the flywheel input direction pushes down the support shaft 12 against the lower ends of the elongated holes 13a and 13b against the wire spring 11, the large-diameter idle gear 14a stops meshing with the drive gear 4. It is released and meshes with the small diameter idle gear 9a. The large-diameter idle gear 9a has a support shaft 7 with a long hole 8
When it descends to the lower end of a, 8b, the small diameter intermediate gear 5
The mesh with b is released. On the other hand, idle gear 9a
is the flywheel 3 of the large diameter idle gear 14a.
When the gear is rotated in the input direction, it is moved upward and meshes with the small-diameter intermediate gear 5b, thereby transmitting the rotation in the input direction to it (see FIG. 2).

A small diameter axle gear 17b is fixed to the axle 16 at a distance from a large diameter axle gear 17a, and the axle gear 17b meshes with a clutch gear 20.
The clutch gear 20 is attached to the support shaft 19 of the clutch gear 20.
1 is loosely fitted, and the clutch gear 21 is pressed against the clutch gear 20 by a spring 22 via a spacer 21a. The clutch gear 21
meshes with a small-diameter intermediate gear 24a, and the small-diameter intermediate gear 24a is provided integrally with a large-diameter intermediate gear 24b. The large diameter intermediate gear 24b is gear 2
7, and the gear 27 meshes with the time counter gear 29. A time counter 30 is provided on the support shaft 28 of the time counter gear 29. Since the time counter 30 is well known, its explanation will be omitted.

Reference numeral 62 is a speed governor for equalizing the rotation of the gear 27, and is rotatably supported on the machine frames 2b, 2c by a support shaft 63. The speed governor 62 includes a clutch 60 provided at the end of the support shaft 26 of the gear 27.
A long groove 64 on which a pin 61 slides is provided, and a weight 65 is provided at the upper end of the governor 62.

Reference numeral 50 denotes a sliding body, which slides in the longitudinal direction of the chassis 1 by loosely fitting a stopper 51 attached to one end and a pin 52 attached to the other end into long holes 57 and 58 drilled in the machine frame 2b, respectively. It is mounted so that it can move freely. The stopper 51 comes into contact with the rear end of the speed governor 62 when the sliding body 50 slides in the Y direction, and stops the swing of the speed governor 62. The weight 55 is rotatably supported inside the machine frame 2b around a support shaft 54, and the pin 52 is attached to the weight 55 through an elongated hole 58. The weight 55 is the pin 5
2 and the elongated hole 58, as well as the pin 59 and the pin 5 provided on the machine frame 2b.
Unnecessary rocking is also suppressed by a spring 56 suspended between the two.

Reference numeral 40 denotes a time counter starting member, which is rotatably supported on the machine frames 2a and 2b about the support shaft 23. The time counter starting member 4
0 has engagement pieces 41a and 41b on both sides that hold the support shaft 12 in that position when the support shaft 12 is pushed down to the lower ends of the elongated holes 13a and 13b. The engagement piece 4
A stopper release piece 42 that engages with a stopper release projection 53 provided at the intermediate portion of the sliding body 50 is provided at the lower end of 1b. Further, the time counter starting member 40 has a support shaft 1 on its upper surface.
It has a claw 44 that engages with the time counter gear 29 when 2 and the engaging pieces 41a and 41b are engaged, and a lever 43 that rotates the time counter starting member 40 about the support shaft 23. The time counter starting member 40 is urged by a spring 45 fitted into the support shaft 23 to rotate in the Z direction about the support shaft 23 .

The present invention has the above-mentioned configuration, and its operation can be explained by using the rear wheels 31a and 31b.
When the axle gear 17a provided on the axle 16 is rotated in the input direction of the flywheel 3 by rubbing it against the floor surface, the support shafts 12 of the idle gears 14a, 14b are pushed down into the lower ends of the elongated holes 13a, 13b. As a result, the engagement between the large-diameter idle gear 14a and the drive gear 4 is released, both ends of the support shaft 12 engage with the engagement pieces 41a and 41b, and the time counter starting member 40 is moved by the spring 45 to the support shaft. 23 in the Z direction, the pawl 44 engages with the time counter gear 29 and stops the time counter 30. Moreover, when the support shaft 12 is pushed down,
The wire spring 11 that was pushing up the support shaft 7 to the upper end of the long holes 8a, 8b is also pushed down, and the support shaft 7 is pushed up to the top of the long holes 8a, 8b.
b Descend to the lower end. As a result, the large-diameter idle gear 9a is disengaged from the small-diameter intermediate gear 5b, and the small-diameter idle gear 9b meshes with the large-diameter idle gear 14a that has descended. Thus, as the large diameter idle gear 14a rotates in the input direction of the flywheel 3, the large diameter idle gear 9a snaps onto the small diameter intermediate gear 5b and transmits rotation through the small diameter idle gear 9a. The rotation of the small diameter intermediate gear 5b is transmitted to the flywheel 3 via the large diameter intermediate gear 5a drive gear 4. In this way, even if an input is made to the flywheel 3, the large diameter idle gear 14a of the drive gear 4
Since the small-diameter intermediate gear 5b and the large-diameter idle gear 9a are disengaged, the axle 16 does not rotate and the traveling toy remains in a stopped state.

When the lever 43 is pushed down, the engagement between the support shaft 12 and the engagement pieces 41a and 41b is released, the support shaft 12 is pushed up to the upper end of the elongated holes 13a and 13b by the wire spring 11, and the large diameter idle gear 14a becomes a driving gear. 4
Resume engagement with. Further, when the lever 43 is pushed down, the sliding body 50 having a stopper release protrusion 53 that engages with the stopper release piece 42 moves in the X direction. As a result, the stopper 51 is separated from the rear end of the speed governor 62, allowing the speed governor 62 to swing, and the weight 55 is moved around the support shaft 54 in the X direction, that is, in the opposite direction to the running direction of the running toy. be rotated. The rotated weight 55 is held in its rotated position by a spring 56. When lever 43 is further pushed down, pawl 44 and time counter gear 2
9 is released, and the time counter 30 can rotate.

Now, when input is made to the flywheel 3 by rubbing the rear wheels 31a and 31b on the floor and the lever 43 is pushed down, the running toy starts running and the time counter 30 starts counting time.
When the running toy is running at high speed, the speed governor 62 suppresses the rotation of the time counter gear 29, thereby increasing the accuracy of measuring running time. When the running toy collides with an obstacle while running, the running toy suddenly stops, and the inertia generated at this time causes the weight 55 to rotate about the support shaft 54 in the Y direction, that is, in the running direction of the running toy. This rotation of the weight 55 causes the stopper 51 to abut the rear end of the speed governor 62 via the sliding body 50, thereby stopping the swinging of the speed governor 62. Therefore, even if the running toy resumes running due to the remaining power of the flywheel 3, no time is counted. At this time, the rotation transmitted from the small diameter axle gear 17b toward the time counter 30 is released by the clutch gear 21.

In the embodiment described above, the rotation of the time counter gear 29 is reliably stopped by the pawl 44 when the input is applied to the flywheel 3, and when the running toy collides with an obstacle, the running toy is stopped by the remaining force of the flywheel 3. When restarting, the stopper 51 stops the flywheel 3.
If the stopper 51 is brought into contact with the rear end of the governor 62 at the time of input, the same effect can be achieved even without the pawl 44.

According to the present invention, time can be counted using the traveling drive source of the traveling toy. Also, time is not counted until the running toy starts running, but time counting starts as soon as running starts, and if the running toy collides with an obstacle and stops suddenly, the time count is stopped due to its inertia. Since the toy stops, it is possible to measure the time the toy travels from when it starts to run until it collides with an obstacle. Furthermore, time is counted by using the rotational force of the flywheel 3, which is the drive source of the traveling toy, but when the toy is running at high speed, the rotation of the time counter gear 29 is suppressed by the action of the speed governor 62. It has become possible to measure travel time with high accuracy.
