Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a four-wheel toy driven by a mainspring.

(Prior Art) Conventionally, as a four-wheel drive toy of this type, a motor drive type toy has been disclosed in Japanese Patent Application No. 53-44430 and Japanese Patent Application No. 58-43024.

(Problems to be Solved by the Invention) Since the motor-driven four-wheel-drive traveling toy described in the above-mentioned prior art needs to be started / stopped by an on / off switch, for example, a place far away from a player. When you can not run in the car, it continues to consume power by idling until the player reaches the same place, there is a fatal defect that unnecessarily shortens the battery life, and the motor due to the decrease in the electromotive force of the battery If it does not work, there is an inconvenience that you can not use it for playing until you replace the battery with a new battery, and the player saves power with his own power and enjoys playing. There were problems such as not being able to do so.

An object of the present invention is to provide a new four-wheel drive traveling toy that solves such problems.

(Means for Solving the Problem) In order to achieve the above object, a four-wheel drive traveling toy according to the present invention has a machine casing 2 fixed to an upper surface of a chassis 1, and a drive shaft 3 and a winding shaft 4 mounted on the machine casing 2. , The transmission shaft 5, the first moving shaft 6, and the second moving shaft 7 are rotatably supported in the front-rear parallel arrangement, and the driving shaft 3 is provided with the driving gear 8 and the transmission shaft 5 is provided with the first transmission gear 9. A second transmission gear 10 which is always meshed with the driving gear 8 is attached to the transmission shaft 5.
Further, the winding gear 11 and the third transmission gear 12 are fixed to the winding shaft 4 so as not to rotate, and a mainspring drum 13 surrounding one end of the winding shaft 4 is provided in the machine casing 2 and is wound into the drum 13. The boss 14 of the gear 11 is inserted to lock the inner end of the mainspring 15 inserted into the drum 13 into the boss 14, and the outer end of the mainspring 15 is also locked to the inner peripheral surface of the drum 13.
The support hole of the moving shaft 6 is an elongated hole 18 having a lower end near the winding shaft 4 and an upper end distant from the upper end, and the first moving shaft 6 is engaged with the winding gear 11 only when the mainspring 15 is released. And a spur gear 20 that meshes with the first transmission gear 9 are non-rotatably fixed to each other to form a first clutch gear portion 21.
The support hole of the moving shaft 7 is formed as a long hole 23 whose lower end is close to the winding shaft 4 and the transmission shaft 5 and whose upper end is distant, and the second moving shaft 7 concerned.
The second clutch gear portion 24, which meshes with the second and third transmission gears 10 and 12 at the same time only when the mainspring 15 is wound, is fixed in a non-rotatable manner. The shaft 26 and the rear driven shaft 27 are connected to the bearing portion 28,
It is supported in the left-right direction and freely rotatable via 28 ',
These front driven shaft 26 and rear driven shaft 27 have traveling wheels 29 non-rotatably fixed to both ends of the front driven shaft 26, and a front small gear 30 and a front crown which mesh with each other at an intermediate portion of the front driven shaft 26 and the front end of the drive shaft 3. The gear 31 is a non-rotatably fixed rear small gear 32 and rear crown gear 33 that mesh with the intermediate portion of the rear driven shaft 27 and the rear end of the drive shaft 3.

(Operation) Since the present invention is configured as described above, when the four traveling wheels 29 are landed and the whole is towed backward, the second clutch gear portion 24 causes the second transmission gear 10 and the third transmission gear 10. The gear 15 simultaneously meshes with the gear 12 to store power in the mainspring 15, and when the power is released onto the floor in the power storage state, the mainspring 15
The disengagement force causes the first clutch gear portion 21 to mesh, and the entire vehicle travels forward with the four traveling wheels 29 landing.

(Effects of the Invention) Since the four-wheel drive traveling toy according to the present invention is as described above, it does not have a short finite portion such as battery consumption in the above-mentioned conventional example, and the player himself stores power to play. And has an excellent effect of sufficiently achieving the intended purpose.

(Example) The machine casing 2 is fixed to the upper surface of the central portion of the chassis 1 and
The drive shaft 3, the winding shaft 4, the transmission shaft 5, the first moving shaft 6, and the second moving shaft 7 are rotatably supported in parallel in the front-rear direction, and the driving gear 8 and the transmission shaft 5 are rotatably supported on the driving shaft 3. A second transmission gear 10 which is constantly meshed with the first transmission gear 9 and the driving gear 8, and a winding gear 11 and a third transmission gear 12 which are fixed to the winding shaft 4 so as not to rotate and wound in the machine casing 2. A mainspring drum 13 surrounding one end of the shaft 4 is provided, the boss 14 of the winding gear 11 is inserted into the drum 13, and the inner end of the mainspring 15 inserted into the drum 13 is inserted into the boss 14. Similarly, the locking balls 16 at the outer ends of the mainspring 15 are respectively locked in the locking grooves 17 provided on the inner peripheral surface thereof, and further, the lower end of the support hole of the first moving shaft 6 is close to the winding shaft 4 and the upper end thereof is The long hole 18 having a distant inclination is formed, and the winding gear 11 is attached to the first moving shaft 6 only when the mainspring 15 is released. The by fixing against rotation pinion 19 which meshes with a spur gear 20 that meshes with the first transmission gear 9 1
The clutch gear portion 21 is formed, and the bearing hole of the second moving shaft 7 is formed as an elongated hole 23 having a lower end near the winding shaft 4 and the transmission shaft 5 and an upper end distant from the upper end.
2nd and 3rd transmission gears 10 and 12 only when the winding operation of
The second clutch gear portion 24 that meshes with the vehicle is fixed non-rotatably, and further, the front driven shaft 26 and the rear driven shaft 27 are placed in the left and right directions and rotate at both front and rear portions of the chassis 1 via the bearing portions 28 and 28 '. The four driven wheels 29 are non-rotatably fixed to both ends of the front side driven shaft 26 and the rear side driven shaft 27, and are meshed with each other at an intermediate portion of the front side driven shaft 26 and the front end of the drive shaft 3. The front small gear 30 and the front crown gear 31, and the rear small gear 32 and the rear crown gear 33, which mesh with each other at the intermediate portion of the rear driven shaft 27 and the rear end of the drive shaft 3, are non-rotatably fixed. It is a thing.

Reference numeral 34 in the drawing denotes a side guide wheel attached to the four corners of the chassis 1 in a freely rotatable state with a vertically oriented short shaft 35 and in a state in which a part thereof is projected outward.
