Description

  The present invention relates to a drive unit using rubber power, and more particularly to a rubber power drive unit that can be used as a power source for a travel toy, airplane toy, boat toy, animal toy, and the like, and a travel toy using the rubber power drive unit.

  Conventionally, a rubber power drive unit includes a case main body, a drive shaft provided on the case main body so as to be rotatable and movable in the front-rear direction, and a rubber-like member provided in the case main body for driving the drive shaft. Become. The drive shaft is provided with a drum having a claw portion. One end of the rubber-like member is attached to a predetermined portion of the toy main body, and the other end is hooked on the claw portion of the drum and wound around the drum.

Conventionally, a rubber power drive unit has wheels attached to both sides of a drive shaft, presses the wheel against a grounding surface, and moves the case main body backward. The claw portion hooks the other end of the rubber-like member, winds the rubber-like member around the drum, and stretches the rubber-like member to store elasticity. In the rubber power drive unit, when the wheel is moved away from the grounding surface, the rubber-like member returns to its original state due to elasticity, so that the drive shaft rotates forward via the drum. When the wheel is in contact with the ground contact surface, the case main body moves forward and the drive shaft moves rearward, so that the claw portion of the drum does not catch the other end of the rubber-like member (for example, Patent Document 1).
JP-A-6-254262

  The conventional rubber power drive unit has a problem that the elasticity of the rubber-like member cannot be stored unless the wheel of the traveling toy incorporating the ground is grounded and the traveling toy is moved backward. Therefore, the conventional rubber power drive unit cannot store the elasticity of the rubber-like member in a stationary state, and therefore has a problem that it can be incorporated only in a traveling toy. In addition, the conventional rubber power drive unit cannot hold the rubber-like member in a state where the elasticity of the rubber-like member is stored, and at the same time when the wheel is separated from the ground surface, the elasticity of the rubber member is released and the wheel rotates. When moving in a state where the elasticity of the rubber-like member is stored, the wheel must be pressed with a finger, so that handling is cumbersome and difficult to handle for infants despite being simple and safe There was a problem.

  The invention of the present application has been devised in view of the above problems, and the elasticity of the rubber-like member can be stored by the hoisting means while the drive shaft is stationary, and the rubber-like member can be stored by the locking means. It is a first object of the present invention to provide a rubber power drive unit that can maintain elasticity. A second object is to provide a traveling toy provided with the rubber power drive unit.

  In order to achieve the first object, a rubber power drive unit according to claim 1 of the present application has a case main body, and the case main body includes a rubber-like member having one end fixed to the case main body, and the rubber-like member. A driving shaft for connecting the other end of the motor, hoisting means for forcibly rotating the driving shaft to wind up the rubber-like member, a driving shaft, and transmitting one rotation of the driving shaft to the driving shaft, A gear group that does not transmit the other rotation of the drive shaft to the drive shaft and a lock unit that locks the drive shaft to prevent the rotation of the drive shaft are provided, and the lock unit locks the drive shaft It is configured to be movable between a locked position and an unlocked position where the drive shaft is not locked.

  In order to achieve the second object, the traveling toy according to claim 2 of the present invention has a toy main body. The toy main body includes a rubber-like member having one end fixed to the toy main body, and the rubber-like member. A driving shaft for connecting ends, hoisting means for forcibly rotating the driving shaft to wind up a rubber-like member, a driving shaft to which driving wheels are attached, and one rotation of the driving shaft to the driving shaft A gear group that transmits and does not transmit the other rotation of the driving shaft to the drive shaft, and a lock means that locks the drive shaft and prevents the rotation of the drive shaft. Can be brought into contact with the grounding surface to be grounded, moves to the lock position for locking the drive shaft when not in contact with the grounding surface, and does not lock the drive shaft when in contact with the grounding surface. It is configured to move to a position .

  In the rubber power drive unit according to the present invention, when the hoisting means is rotated while holding the case main body, the driving shaft rotates in one direction, and the rubber-like member is wound up so that elasticity can be stored. Since the rotation of the driving shaft to one side is not transmitted to the driving shaft via the gear group, the driving shaft does not rotate. When the rotation of the hoisting means is stopped, the wound rubber-like member is restored to the original state by the elastic restoring force, so that the driving shaft tries to rotate in the other direction. The rotation of the drive shaft to the other is transmitted to the drive shaft via the gear group, but the lock means is in the lock position for locking the drive shaft, so that the rotation of the drive shaft is prevented and remains stopped. is there.

  Therefore, the rubber power drive unit according to the present invention can store the elasticity of the rubber-like member in a state where the drive shaft is stationary, and can further hold the elasticity of the rubber-like member by the lock means. There is an effect that can be done. Moreover, the lock means can be unlocked simply by moving the lock means to an unlocked position where the drive shaft is not locked, the elasticity stored in the rubber-like member is released, and the drive shaft can be easily rotated. There is an effect that can be done. Thus, the rubber power drive unit according to the present invention stores the elasticity of the rubber-like member by the hoisting means while the drive shaft is stationary, and holds the stored elasticity of the rubber-like member by the locking means. When the lock means is released, the stored elasticity of the rubber-like member is released and the drive shaft rotates, so there is no need to rotate the drive shaft and wind up the rubber power as in the past. There is an effect that power can be stored and the stored elasticity can be reliably maintained.

  In the traveling toy according to the present invention, when the hoisting means is rotated while holding the toy main body, the driving shaft rotates in one direction, and the rubber-like member is wound up to store elasticity. Since the rotation of the driving shaft to one side is not transmitted to the driving shaft via the gear group, the driving shaft and the driving wheel do not rotate. When the rotation of the hoisting means is stopped, the wound rubber-like member is restored to the original state by the elastic restoring force, so that the driving shaft tries to rotate in the other direction. The rotation of the drive shaft to the other is transmitted to the drive shaft via the gear group, but the lock means is in the lock position for locking the drive shaft, so that the rotation of the drive shaft is prevented and remains stopped. is there.

  Therefore, the traveling toy according to the present invention can store the elasticity of the rubber-like member in a state where the drive shaft and the driving wheel are stationary, and further hold the elasticity of the rubber-like member by the lock means. There is an effect that can be. In addition, the lock means can be unlocked simply by moving the lock means to an unlocked position where the drive shaft is not locked, the elasticity stored in the rubber-like member is released, and the drive shaft and drive wheels can be easily rotated. There is an effect that can be made. Thus, in the traveling toy according to the present invention, the elasticity of the rubber-like member is stored by the hoisting means while the drive shaft is stationary, and the elasticity of the stored rubber-like member can be held by the locking means. When the locking means is released, the stored elasticity of the rubber-like member is released and the drive shaft and the drive wheel rotate. Therefore, as in the past, it is troublesome to rotate the drive wheel while pressing it against the grounding surface to increase the rubber power. Therefore, there is an effect that power can be easily stored and the stored elasticity can be reliably maintained.

  One embodiment of a rubber power drive unit (running toy) according to the present invention will be described with reference to FIGS. FIG. 1 is an overall perspective view of a rubber power drive unit (running toy) as viewed from one side. FIG. 2 is an overall perspective view of the rubber power drive unit (traveling toy) as viewed from the other side. FIG. 3 is an overall perspective view of the rubber power drive unit (traveling toy) as viewed from below. FIG. 4 is a plan view of the rubber power drive unit (traveling toy). FIG. 5 is a side view of the rubber power drive unit (traveling toy). FIG. 6 is a cross-sectional view of a main part of a rubber power drive unit (traveling toy). FIG. 7 is an operation explanatory diagram of the rubber power drive unit (traveling toy).

The rubber power drive unit 1 has a case body 2. The case main body 2 includes a rubber-like member 15 having one end fixed to the case main body 2, a driving shaft 11 connecting the other end of the rubber-like member 15, and the driving shaft 11 forcibly rotating to form a rubber-like member. A hoisting means 40 for winding up the member 15, a drive shaft 21, and a gear group that transmits one rotation of the driving shaft 11 to the driving shaft 21 and does not transmit the other rotation of the driving shaft 11 to the driving shaft 21. 20 and a lock means 45 that locks the drive shaft 21 to prevent the drive shaft 21 from rotating. The lock means 45 is configured to be movable to a lock position P1 where the drive shaft 21 is locked and a non-lock position P2 where the drive shaft 21 is not locked.

  In the rubber power drive unit 1, when the hoisting means 40 is rotated while holding the case body 2, the driving shaft 11 rotates in one direction, and the rubber-like member 15 can be wound up to store elasticity. Since the rotation of the driving shaft 11 to one side is not transmitted to the driving shaft 21 via the gear group 20, the driving shaft 21 does not rotate. When the rotation of the hoisting means 40 is stopped, the wound rubber-like member 15 returns to the original state by the elastic restoring force, so that the driving shaft 11 tries to rotate in the other direction. The rotation of the drive shaft 11 to the other side is transmitted to the drive shaft 21 via the gear group 20. However, since the lock means 45 is in the lock position P1 where the drive shaft 21 is locked, the rotation of the drive shaft 21 is prevented. Stopped and remains stopped.

  Therefore, the rubber power drive unit 1 can store the elasticity of the rubber-like member 15 in a state where the drive shaft 21 is stationary, and further holds the rubber-like member 15 in a state where the elasticity of the rubber-like member 15 is stored by the lock means 45. Can do. Further, the lock means 45 can be unlocked only by moving the lock means 45 to the unlocked position P2 where the drive shaft 21 is not locked, and the stored elasticity of the rubber-like member 15 is released. 21 can be rotated. Thus, in the rubber power drive unit 1, the elasticity of the rubber-like member 15 is stored by the hoisting means 40 with the drive shaft 21 stationary, and the elasticity of the stored rubber-like member 15 is stored by the lock means 45. When the lock means 45 is released, the stored elasticity of the rubber-like member 15 is released and the drive shaft 21 rotates. Thus, as in the conventional case, the drive shaft 21 is rotated and the rubber power is wound up. Therefore, it is possible to easily store power and to securely retain the stored elasticity.

  The traveling toy 1 has a toy body 2. The toy body 2 has a rubber-like member 15 having one end fixed to the toy body 2, a driving shaft 11 that connects the other end of the rubber-like member 15, and the driving shaft 11 is forcibly rotated to form a rubber-like shape. The hoisting means 40 for winding up the member 15, the drive shaft 21 to which the drive wheel 31 is attached, and one rotation of the driving shaft 11 is transmitted to the driving shaft 21, and the other rotation of the driving shaft 11 is driven. A gear group 20 that does not transmit to the shaft 21 and a lock means 45 that locks the drive shaft 21 and prevents the drive shaft 21 from rotating are provided. The locking means 45 can be brought into contact with the grounding surface 35 to which the driving wheel 31 is grounded, and moves to the lock position P1 for locking the drive shaft 21 when not in contact with the grounding surface 35. The drive shaft 21 is configured to move to an unlocked position P2 where the drive shaft 21 is not locked.

  In the traveling toy 1, when the hoisting means 40 is rotated while holding the toy body 2, the driving shaft 11 rotates in one direction, and the rubber-like member 15 can be wound up to store elasticity. Since the rotation of the driving shaft 11 to one side is not transmitted to the driving shaft 21 via the gear group 20, the driving shaft 21 and the driving wheel 31 do not rotate. When the rotation of the hoisting means 40 is stopped, the wound rubber-like member 15 returns to the original state by the elastic restoring force, so that the driving shaft 11 tries to rotate in the other direction. The rotation of the drive shaft 11 to the other side is transmitted to the drive shaft 21 via the gear group 20. However, since the lock means 45 is in the lock position P1 where the drive shaft 21 is locked, the rotation of the drive shaft 21 is prevented. Stopped and remains stopped.

  Therefore, the traveling toy 1 can store the elasticity of the rubber-like member 15 with the driving shaft 21 and the driving wheel 31 being stationary, and is further held by the lock means 45 with the elasticity of the rubber-like member 15 being stored. can do. Further, the lock means 45 can be unlocked only by moving the lock means 45 to the unlocked position P2 where the drive shaft 21 is not locked, and the stored elasticity of the rubber-like member 15 is released. 21 and the drive wheel 31 can be rotated. Thus, in the traveling toy 1, the elasticity of the rubber-like member 15 is stored by the hoisting means 40 with the drive shaft 21 stationary, and the stored elasticity of the rubber-like member 15 is held by the lock means 45. When the locking means 45 is released, the stored elasticity of the rubber-like member 15 is released and the drive shaft 21 and the drive wheel 31 rotate. Therefore, the drive wheel 31 is rotated while being pressed against the grounding surface as in the prior art. Therefore, there is no inconvenience of winding up the rubber power, the power can be stored easily, and the stored elasticity can be reliably maintained.

  Further, the rubber power drive unit 1 will be described in detail. As shown in FIGS. 1 to 3, the case body 2 is formed in a rectangular box shape, and includes a bottom wall 3, a front wall 5, a rear wall 6, a right wall 7, and a left wall 8. The case body 2 is substantially parallel to the right wall 7 and is provided with a partition wall 9 connected to the front wall 5 and the rear wall 6. A space 10 is formed between the right wall 7 and the partition wall 9, and a later-described gear group 20 is provided in the space 10.

  As shown in FIG. 4, the drive shaft 11 and the drive shaft 21 are attached to the case main body 2 substantially in parallel. The driving shaft 11 is rotatably attached to the right wall 7 and the partition wall 9. A driving gear 12 is fixedly attached to the driving shaft 11 inside the space 10. A substantially inverted J-shaped hook 13 is attached to one end of the driving shaft 11 protruding from the partition wall 9 toward the left wall 8. One end of the rubber-like member 15 is hooked on the hook 13. The other of the rubber-like members 15 is hooked on a projecting piece 18 formed on the left wall 8 by a pair of notches 16 and 17.

  The drive shaft 21 is rotatably attached to the right wall 7 and the left wall 8, and a driven gear 22 is fixedly attached to the inside of the space 10. A planetary gear 25 is provided between the driven gear 22 and the driving gear 12. As shown in FIG. 7, the intermediate shaft 26 to which the planetary gear 25 is attached has the planetary gear 25 always meshed with the driving gear 12 and the planetary gear 25 is driven when the driving gear 12 rotates counterclockwise (anti-X direction). It is separated from the gear 22 and is rotated in a bearing slot 27 formed in the right wall 7 and the partition wall 9 so that the planetary gear 25 meshes with the driven gear 22 when the driving gear 12 rotates in the clockwise direction (X direction). It is attached as possible. By the driving gear 12, the planetary gear 25, and the driven gear 22, one rotation (X direction) of the driving shaft 11 is transmitted to the drive shaft 21, and the other rotation (anti-X direction) of the driving shaft 11 is transmitted to the driving shaft. A gear group 20 that does not transmit to 21 is configured.

  A hoisting shaft 41 is rotatably provided between the right wall 7 and the partition wall 9. A hoisting gear 42 that always meshes with the driving gear 12 is fixedly attached to the hoisting shaft 41. A knob 43 is fixedly attached to the tip of the hoisting shaft 41 protruding outward from the right wall 7. The hoisting shaft 41, the hoisting gear 42, and the knob 43 constitute hoisting means 40 that forcibly rotates the driving shaft 11 to wind up the rubber-like member 15.

  In the space 10, locking means 45 is provided that engages with the driven gear 22 to lock the drive shaft 21. As shown in FIG. 6, the locking means 45 includes an elongated plate-like operating member 46 and a locking member 47 provided on one side 46 a of the operating member 46. In the present embodiment, the locking member 47 is formed in the shape of a gear, but it may be in the shape of a locking claw. In short, when it comes into contact, the rotation of the drive shaft 21 is prevented and separated. Any structure that allows rotation of the drive shaft 21 is acceptable.

  The operating member 46 is movable in a direction in which the locking member 47 is locked to the driven gear 22 and in a direction in which the locking member 47 is separated from the driven gear 22, and is biased in the locking direction by its own weight. The operating member 46 may be biased in the locking direction by an elastic member such as a spring. The other 46 b of the operating member 46 projects from an opening 3 a formed in the bottom wall 3 of the case body 2. The actuating member 46 is guided in the vertical direction by the guide member 28 formed on the bottom wall 3 and is prevented from jumping out by the stopper piece 29 provided on the partition wall 9.

  The rubber power drive unit 1 has the above-described configuration, and in the initial state, as shown in FIG. 7A, the locking member 47 of the lock means 45 meshes with the driven gear 22 by its own weight, and the lock means Reference numeral 45 denotes a lock position P1 that locks the drive shaft 21, and the drive shaft 21 is locked to prevent the drive shaft 21 from rotating. In this state, when the knob 43 is gripped and the hoisting shaft 41 is rotated clockwise (X direction), the hoisting gear 42 is also rotated clockwise (X direction) as shown in FIG. 7B. The driving gear 12 meshing with this rotates counterclockwise (counter X direction). As the driving gear 12 rotates, the driving shaft 11 and the hook 13 rotate and wind the rubber-like member 15. The planetary gear 25 is separated from the driven gear 22 following the rotation of the driving gear 12 in the counterclockwise direction (counter-X direction), so that the rotation of the driving gear 12 is not transmitted to the driven gear 22. Thus, the rubber power drive unit 1 stores the elasticity of the rubber-like member 15 by rotating the hoisting shaft 41 in the clockwise direction (X direction).

  As shown in FIG. 7A, when the knob 43 is released, the driving gear 12 tends to rotate clockwise (X direction) due to the elasticity of the rubber-like member 15. The planetary gear 25 meshes with the driven gear 22 following the rotation of the driving gear 12 in the clockwise direction (X direction). As described above, since the driven gear 22 is locked by the locking member 47 of the locking means 45, the rotation is prevented. Therefore, the rotation of the driving gear 12 in the clockwise direction (X direction) is transmitted to the driven gear 22 but is blocked because the driven gear 22 is locked.

  As shown in FIG. 7C, when the operating member 46 is moved in the counter-locking direction, the locking member 47 is separated from the driven gear 22, so that the locking means 45 is in the unlocked position P <b> 2 where the drive shaft 21 is not locked. The driven gear 22 and the drive shaft 21 are unlocked, the stored elasticity of the rubber-like member 15 is released, and the driven gear 22 is rotated clockwise (X direction) by the elastic restoring force of the rubber-like member 15. Rotate to. The rotation of the driven gear 22 in the clockwise direction (X direction) is transmitted to the drive shaft 21, and the drive shaft 21 rotates in the clockwise direction (X direction).

  The rubber power drive unit 1 can be applied to the traveling toy 1. Drive wheels 31, 31 are attached to both sides of the drive shaft 21 described above. On the rear wall 6 side of the case body 2, an idle shaft 32 that is substantially parallel to the drive shaft 21 is rotatably provided. The idle wheels 33 are attached to both sides of the idle shaft 32. In this way, the rubber power drive unit 1 can be used as the traveling toy 1. The other 46b of the operating member 46 of the locking means 45 needs to protrude beyond the ground contact surface 35 where the drive wheel 31 and the idle wheel 33 are grounded.

  When the traveling toy 1 is in an initial state, as shown in FIG. 7A, the locking member 47 of the locking unit 45 meshes with the driven gear 22 by its own weight, and the locking unit 45 locks the drive shaft 21. At the locked position P1, the drive shaft 21 is locked and rotation of the drive shaft 21 is prevented. In this state, when the knob 43 is gripped and the hoisting shaft 41 is rotated clockwise (X direction), the hoisting gear 42 is also rotated clockwise (X direction) as shown in FIG. 7B. The driving gear 12 meshing with this rotates counterclockwise (counter X direction). As the driving gear 12 rotates, the driving shaft 11 and the hook 13 rotate and wind the rubber-like member 15. The planetary gear 25 moves away from the driven gear 22 following the rotation of the driving gear 12 in the counterclockwise direction (counter-X direction), so that the rotation of the driving gear 12 is applied to the driven gear 22, the drive shaft 21, and the drive wheels 31, 31. Not transmitted. As described above, the traveling toy 1 stores the elasticity of the rubber-like member 15 in a state where the driving wheel 31 is stopped without moving by rotating the hoisting shaft 41 in the clockwise direction (X direction). .

  As shown in FIG. 7A, when the knob 43 is released, the driving gear 12 tends to rotate clockwise (X direction) due to the elasticity of the rubber-like member 15. The planetary gear 25 meshes with the driven gear 22 following the rotation of the driving gear 12 in the clockwise direction (X direction). As described above, since the driven gear 22 is locked by the locking member 47 of the lock means 45, the rotation of the drive shaft 21 and the drive wheels 31, 31 is prevented. Therefore, the rotation of the driving gear 12 in the clockwise direction (X direction) is transmitted to the driven gear 22, but is prevented because the drive shaft 21 is locked by the locking means 45.

  As shown in FIG. 7C, when the driving wheels 31 and 31 and the idle wheels 33 and 33 are grounded to the ground surface 35, the other 46 b of the operating member 46 comes into contact with the ground surface 35, and the operating member 46 is counteracted. Pushed up in the locking direction. When the actuating member 46 is pushed up in the counter-locking direction (upward), the locking member 47 moves away from the driven gear 22, so that the locking means 45 moves to the unlocked position P <b> 2 where the drive shaft 21 is not locked and the driven gear 22 And the lock | rock of the drive shaft 21 is cancelled | released, the elasticity stored in the rubber-like member 15 is released, and the driven gear 22 rotates clockwise (X direction) by the elastic restoring force of the rubber-like member 15. The clockwise rotation (X direction) of the driven gear 22 is transmitted to the drive shaft 21, and the drive shaft 21 and the drive wheels 31, 31 rotate in the clockwise direction (X direction). Since the driving wheels 31, 31 rotate, the traveling toy 1 travels. Even when all the stored elasticity of the rubber-like member 15 is released and the rotation of the driving gear 12 and the planetary gear 25 is stopped, the planetary gear 25 is rotated by the clockwise rotation (X direction) of the driven gear 22. Is repelled away from the driven gear 22, the clockwise direction (X direction) of the driven gear 22 is less affected by the planetary gear 25.

  In the present embodiment, the rubber power drive unit 1 has been described as a traveling toy. However, the rubber power drive unit 1 is attached to an airplane toy to drive a propeller, is attached to a boat toy to drive a screw, and is attached to an animal toy. It can also be set as the drive part which drives an arm part and a leg part.

  The present invention can be used as a rubber power drive unit for toys such as traveling toys, airplane toys, boat toys and animal toys.
