JPS5920314Y2 - Reset mechanism in counter device of racing toy - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a noset mechanism in a counter device for a racing toy.

Conventionally, in the counter device of a general racing toy, a count lever protrudes from the outside of the track onto the track, and this count lever is linked via a ratchet wheel with a rotary disk for counting display that has a pointer on the top surface. The rotary disk rotates intermittently every time the vehicle swings the count lever while the vehicle is running, and the pointer on the top of the disk rotates intermittently to indicate the count scale.
The count is displayed after each scale is sent.

With such a counter device, there is no particular problem in being able to display the count, but it is difficult for children to return the count display to the initial 0 position after one game. there were.

In other words, it is difficult to rotate the turntable with your fingertips and stop the pointer accurately at the 0 position on the count scale, and the pointer may go too far past 0 or stop short of 0, but this does not allow you to play the game properly.

The present invention is an improvement on the above-mentioned drawbacks, and according to the reset mechanism of the present invention, the recessed part provided on the top surface of the rotary plate for count display is placed with a finger and pressed slightly downward, and the reset direction is reset. When the pointer returns to the O position, the protruding piece provided on the lower surface of the rotary disk engages with the stopper provided upright on the bottom plate of the housing, so that the pointer provided on the upper surface of the rotary disk can be easily and accurately adjusted. It can be returned to the 0 position.

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is the track of the race toy, 2 is a counter device installed on the side of the track, 3 is the housing of the counter device, 4 is a count lever whose tip protrudes above the track 1, and 5 is for displaying the count. , and 6 is a running body.

To explain the counter device 2 in more detail, an open lower is formed on the side plate 3b of the housing 3 on the track side, and during this time, the above-mentioned count lever 4 projects from the lower onto the track.

The base of the count lever 4 is a cylindrical body 4a, and is pivotably supported on a support shaft 8 that stands up from the bottom plate 3a of the housing 3.

Further, a claw member 4b integrally extends from the cylinder 4a in a V-shape, and a spring 25 is applied in one direction, so that the left and right claws can be alternately engaged and disengaged with the claws of the rook 9, and this makes the escape mechanism It consists of

The rook 9 is mounted on a shaft 10 supported by a cylindrical shaft 11 on the bottom plate 3a of the housing 3.

A small gear 12 is integrally provided on the upper surface of the rook 9,
It meshes with a large gear 13 that is integrally provided at the bottom of the rotary disk 5.

The turntable 5 for count display is on the upper wall 3C of the housing 3.
It is exposed through an opening 14 provided in the upper surface thereof, and has a concave portion 16 on the upper surface, on which the fingertip is applied in addition to the pointer 15 to rotate the rotary disk 5 during resetting.

The shaft 17 to which the rotary disk 5 is attached is attached to the bottom plate 3 of the housing 3.
It is inserted into a cylindrical bearing 18 provided at a to be able to move up and down, and is pushed upward by a push spring 19.

Reference numeral 20 denotes a protruding piece provided on the lower surface of the rotary disk 5, and a protruding stopper is provided on the bottom plate 3a of the housing 3 corresponding to the protruding piece 20 and at a position on the locus of rotation of the protruding piece 20. 2
1 is provided.

The upper end of the stopper 21 and the lower end of the protruding piece 20 are connected to the push spring 1
Under normal conditions, when the rotary disk 5 is pushed up at 9 and the number of laps of the traveling body is counted, they do not engage with each other.
When rotating the rotary disk 5 by pressing down the concave portion 16 with the fingertip 22, the edge 21a of the stopper 21 and the edge 20 of the protrusion 20 are pressed down.
a are provided so as to engage with each other.

Moreover, the stopper 21 and the protruding piece 20 touch the pointer 15 on the rotary disk 5 when the end edges 21 a and 203 are engaged with each other.
is provided to indicate the zero point on the count scale 23 provided on the top surface of the housing 3.

Therefore, according to the above configuration, when the traveling vehicle 6 passes the counter device 2 on the track 1, the count lever 4 swings and passes through the pawl member 4b, the rook 9, the small gear 12, and the large gear 13 to the rotary disk. 5 rotates intermittently, and the pointer 15 advances one division at a time on the count scale 23.

At this time, the rotary disk 5 is pushed up by the push spring 19, and the protruding piece 20 can pass above the stopper 21 without engaging with it.

At the end of one game, in order to reset the pointer 15, which has been rotated by a predetermined angle, back to the O position on the count scale 23, place your fingertip on the concave portion 16 and press the rotary disk 5 to rotate it in the opposite direction against the spring 19. At this time, the end edge 20a of the protruding piece 20 and the end edge 21a of the stopper 21 are often engaged and stopped, whereby the pointer 15 indicates O on the count scale 23.

Although the embodiments have been described below, the present invention is such that the turntable for count display is vertically movable and is normally lifted by a push spring, and at this time, it does not engage with the protruding stopper provided on the bottom plate. A protrusion is provided at the bottom of the rotary disc that engages only when the rotary disc is pushed down and rotated, and the pointer is set so that the count scale indicates 0 when the stopper and the protrusion are engaged, so racing play is avoided. When resetting the counter device, the child can easily and accurately return the pointer on the count display turntable to the O position on the count scale, allowing the game to proceed smoothly.
