Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] This invention relates to a starting device for energizing and starting a toy automobile.

[Conventional technology]

Conventionally, as shown in, for example, US Pat. A propulsion member protruding from the propulsion member is engaged in a movable manner, the propulsion member is connected to the starting platform by a propulsion spring, and a protrusion for locking the retaining portion of the propulsion member is provided near the starting end of the running path of the starting platform, and a push button. Some devices are equipped with an operating mechanism that elastically deforms the retaining portion under pressure to release the lock.

This starting device engages a part of the body of a toy car with a propulsion member, moves the propulsion member backward, and extends a propulsion spring.
The vehicle is positioned on the starting end of the traveling path, and the retaining portion is engaged with a protrusion provided on the starting platform to hold the propulsion member and the vehicle on the starting end of the traveling path. In this state, press the push button on the operating mechanism to release the latch from the retaining part to the protrusion, and use the spring force of the propulsion spring to move the propulsion member forward along the guide hole, thereby propelling the car forward along the road. I'm trying to promote it.

[Problem that the invention seeks to solve]

The conventional toy car starting device described above uses the spring force of the propulsion spring to move the propulsion member forward along the guide hole, thereby propelling the car forward on the running path. Due to manufacturing errors in the mounting part of the propulsion spring, the toy car may turn left or right, so it is possible to make the car go straight by providing side plates along the longitudinal direction on both sides of the running path. However, there was a problem that the straightness was not good. In addition, conventional starting devices only momentarily provide propulsion to the toy car using the spring force of the extended propulsion spring, but the propulsion force is not sustainable, so the speed of the toy car decreases rapidly after starting. There was also the problem of doing so.

The present invention solves the above-mentioned problems and provides a starting device for a toy car that has good straightness, sustained propulsion, and does not suddenly reduce the speed of the toy car after starting. It is an object.

[Means for solving problems]

The toy car starting device according to the present invention has a toy car running path formed on a starting platform, a guide hole formed in the starting platform along the longitudinal direction of the running path, and a guide hole that is movably engaged with the guide hole. A propulsion member having a portion protruding onto the running road and the protrusion engaging the vehicle body of the automobile, and a propulsion spring coupled to the propulsion member and a starting platform and biasing the propulsion member in the forward direction, A retaining piece disposed at the starting end of the running path of the starting platform and removably engaging with the body of the toy car, and a flywheel type drive mechanism of the toy car with a portion protruding above the starting end of the running path. an energizing width that frictionally engages with a drive wheel connected to the energizing width; a pinion fixed to a shaft supporting the energizing width in a starting platform; It is equipped with a starting mechanism for releasing the engine, a rack that engages with the pinion, and an energizing belt that is removably inserted into the starting platform and has an operation protrusion that operates the starting mechanism. The flywheel of the toy car positioned above the starting end of the traveling path is energized by pulling out the energizing belt through the energizing wheel and the driving wheel, thereby operating the starting mechanism.

[For production]

The starting device for a toy car according to the present invention has an energizing belt inserted into the starting platform, a rack of the energizing belt meshing with a pinion, and an operating projection located in front of the starting mechanism. Similarly, the body of the toy car is engaged with the propulsion member, the propulsion member is moved backward, the propulsion spring is extended, and the car is positioned above the starting end of the running path. The vehicle body is locked, and the propulsion member and the vehicle are held on the starting end of the traveling path in a state where the drive wheels of the vehicle are frictionally engaged with the energizing wheels coaxial with the pinion. In this state, by pulling the energizing belt backward from the starting platform parallel to the running path, the pinion is rotationally driven by the rack of the energizing belt, and this driving force is transmitted to the energizing transport via the shaft. The drive wheels of the vehicle are rotated to charge the flywheel drive mechanism. By pulling the energizing belt further rearward, the starting mechanism is operated by its operation protrusion, and the locking between the retaining piece and the car body is released, and the spring force of the propulsion spring is released in the same way as in the conventional starting device described above. The propulsion member and the vehicle are propelled forward on the road. At the same time, the rotational force stored in the flywheel drive mechanism is released and the drive wheels of the vehicle are driven. Therefore, according to the present invention, when the energizing belt is pulled out, the automobile is energized by the spring force of the propulsion spring and the rotational force stored in the flywheel type drive mechanism, and is launched forward on the traveling road. Since the drive wheels are driven by the drive mechanism, the vehicle has good straight-line performance and does not turn left or right, and the flywheel mechanism of the drive wheels has relatively good sustainability, so the propulsion force can be sustained. The speed of the car does not suddenly decrease after starting.

Furthermore, the left and right rear wheels 35 are arranged at a vehicle width that matches the energizing width 16.

To start the toy car 8 using the starting device of the embodiment configured as described above, proceed as follows.

The energizing belt 28 is loosely inserted into the starting platform 1 through the insertion opening 29 provided on the rear end wall 5a of the protrusion 5, and supported within the bell I-X 30, and the rack 32 is installed on the shaft 17 with an energizing width of 16. It is passed between the eccentric cam 23b provided on the holding member 23 of the starting mechanism 21 and the support piece 22b provided on the retaining release piece 22, and the operation protrusion 31 is positioned in front of these. In this case, the biasing belt 28 extends parallel to the running path 4 so that the grip 33 remains outside the starting platform 1. Further, the shaft 17 provided with the biasing width 16 and the pinion 18 is sent to the front end of the inclined groove 19 against the tension spring 20 by the insertion of the biasing belt 28 and the meshing of the pinion 18 and the biasing belt 28. Since the pressing member 23 is biased by the spring force of the spring 24 of the starting mechanism 21, the biasing belt 28 is pressed against the support piece 22b by its eccentric cam 23b. In this state, the engaging portion 7a of the propulsion member 7 is engaged with the rear surface of the engagement protrusion 9a provided on the front lower part of the vehicle body 9 of the toy car 8, and the propulsion member 7 is moved along the guide hole 6 to the front end of the running path 4. At the same time, the automobile 8 moves backward and reaches the starting end 4a of the traveling path 4. Alternatively, only the propulsion member 7 may be moved backward in advance, and the engagement protrusion 9a and the engagement portion 7a may be engaged with each other on the starting end 4a of the travel path 4 as described above. At the starting end 4a of the running path 4, the locking part 9b provided at the middle part of the vehicle body 9 of the automobile 8 is engaged with the retaining protrusion 14a of the retaining piece 14 from the rear, and the rear end of the vehicle body 9 is engaged with the retaining projection 14a of the retaining piece 14. The provided cylindrical portion 9C is brought into contact with a vehicle body presser 27 provided on the protrusion 5 of the starting platform 1 from below to prevent the rear part of the automobile 8 from lifting up when starting, which will be described later. In this state, the driving wheels 35 of the automobile 8 are substantially supported by the portions of the auxiliary wheels 16 that protrude upward from the window holes 15, and the automobile 8 is held on the starting end 4a of the traveling path 4.

Incidentally, after the automobile 8 is held on the starting end 4a of the traveling path 4, the above-mentioned energizing belt 28 may be inserted into the starting platform 1. Next, hold the grip 33 at the rear of the starting platform l and pull out the energizing belt 28 in a direction parallel to the running path 4. Depending on the situation, the linear motion of the energizing belt 28 is converted into the rotational motion of the pinion 18 and transmitted to the energizing wheel via the shaft 17, and at the same time, the shaft 17 moves backward and upward in the inclined groove 19, thereby energizing the belt. The wheel 16 rises and frictionally engages with the driving wheel 35 of the automobile 8, and rotational force is transmitted from the auxiliary wheel 16 to the driving wheel 3.
5, the rotation of the drive wheel 35 is transmitted to the flywheel 37 of the flywheel type drive mechanism 36 and the gear 42. The drive mechanism 3 is transmitted through the intermediate gears 39 and 40.
Power is stored at 6. In this case, the auxiliary wheel 16 and the drive wheel 35
The rotational force of the energizing wheel 16 is reliably transmitted to the driving wheel 35 by the engagement of the small uneven portions 16a and 35a formed on the outer periphery of the energizing wheel 16. By pulling the auxiliary belt 28 backward,
When the operation protrusion 31 provided at the tip thereof passes between the eccentric cam 23b of the starting mechanism 21 and the support piece 22b, the support piece 22b is pushed downward, and the retaining release piece 22 and the retaining piece 14 are elastically deformed together from the connected portion of the retaining piece 14, and the retaining protrusion 14a provided on the retaining piece 14 descends. Therefore, the retaining protrusion 14a and the locking portion 9b of the vehicle body 9
The lock is released, and the automobile 8 is propelled forward along the traveling path 4 together with the propulsion member 7 by the spring force that causes the propulsion spring 11 to shorten. At the same time, the rotational force stored in the flywheel drive mechanism 36 is released and the drive wheels 35 are driven. That is, when the energizing belt 28 is pulled out, the automobile 8 is started forward on the traveling path 4 by the spring force of the propulsion spring 11 and the rotational force stored in the flywheel drive mechanism 36. Then, the drive wheels 35 are driven by the release of the drive force stored in the flywheel type drive mechanism 36, so that the automobile 8 can travel in a straight line with good straightness, and a sustainable propulsive force can be obtained. The speed of the automobile 8 does not suddenly decrease after starting. At the time of this start, the energizing belt 28 does not need to be pulled out from the starting platform 1 over its entire length, but it is necessary to pull it out at least until the operating protrusion 31 reaches the rear of the space between the eccentric cam 23b and the support piece 22b of the starting mechanism 21. . Thereafter, the automobile 8 can be started by repeating the above-described operations. In this embodiment, it is also possible to increase the driving force by stopping the energizing belt for storing energy in the flywheel drive mechanism 36 without pulling it out all at once, and then inserting it again and pulling it out further.

Further, in this embodiment, small uneven portions are provided on the outer circumferences of the energizing wheels and the driving wheels of the automobile, but the small uneven portions may be omitted in the present invention. Furthermore, in the present invention, the configuration of the starting mechanism and the configuration of the flywheel drive mechanism mounted on the toy car are not limited to those of the embodiments, and can be changed as appropriate.

〔Effect of the invention〕

As explained above, according to the present invention, by pulling out the energizing belt inserted into the starting platform, rotational force is stored in the flywheel drive mechanism connected to the drive wheels of the toy car via the energizing wheel. By operating the starting mechanism after the driving mechanism is activated, the automobile can be started by driving the driving wheels by the spring force of the propulsion spring and the rotational force released from the driving mechanism. Therefore, the present invention According to the above, it is possible to obtain good straight-line performance at the time of starting, to obtain a sustainable propulsive force, and to prevent the speed of the automobile from suddenly decreasing after starting.
