Is configured to be transmitted to the accumulator spring holder via the transmission gear. Therefore, in the invention described in any of these claims, directly by the turning operation of the handle portion or The power storage unit is configured to store power via a transmission gear, and when the handle unit is rotated, it is necessary to perform the rotation operation against the spring pressure of the power storage spring. In addition, a predetermined operation force is required to rotate the handle portion.

In the inventions according to claims 8 to 11, when the operator operates the start switch, the motor is started, and the motive power of the motor is transmitted to the accumulator spring holder, so that the starter can be easily operated. To start the engine.
Accordingly, since the engine can be started without performing a manual operation such as a recoil rope drawing operation, it is possible to reduce the labor required for the operator's operation when starting the engine.
In particular, in the invention described in claim 11, since the first drive unit that can be driven manually and the second drive unit configured by the motor are provided, there is a problem such as the battery running out of the motor. When this occurs, the engine can be started by accumulating power by manually operating the recoil rope and operating the starter.

In the invention according to claim 12, even if the force storage spring holder is rotated between the force storage spring holder and the second drive portion by the pulling operation of the recoil rope, the rotation drive thereof Since there is a one-way clutch that does not transmit the force to the motor, the rotation of the accumulator spring holder is transmitted to the drive force transmission gear part when the recoil rope is pulled out to store the force. Even if it is a case, it is not transmitted to a motor by the said one-way clutch, and the load to the manual operation by the motor provided as the drive part at the time of the manual operation by pulling out the recoil rope can be eliminated.
Therefore, it is possible to realize a light accumulation operation using the recoil rope.

In the inventions according to claims 13 to 19, a stopper that engages with the engagement protrusion and prevents the rotation of the ratchet pulley is disposed in the groove formed in the side surface of the ratchet pulley that constitutes the driven portion. At the time of release, the driving force accumulated in the energy storage spring is released by the rotation of the ratchet pulley with the stopper placed in the groove.

In the inventions according to claims 16 to 18, since the groove is formed with a length dimension that is longer than a length dimension required until the accumulator spring is completely released, After the release of the driving force of the energy storage spring is completed, the stopper returns to the initial position, and the stopper is held for a predetermined time after the energy storage spring is released, which was attached to the conventional lock energy storage starter device. A stopper engagement delay mechanism configured to bias the ratchet pulley so as not to engage with the ratchet pulley can be omitted.

Therefore, since the components and supporting members that constitute the biasing means necessary for the stopper engagement delay mechanism can be omitted, the number of component parts as a whole of the lock type force accumulation starter device can be further reduced. The manufacturing cost can be reduced.

  According to the nineteenth aspect of the present invention, the stopper engaging protrusion is reduced by reducing the contact speed of the stopper with the stopper engaging protrusion due to the high speed rotation of the ratchet pulley when the force of the accumulating spring is released. Since the impact on the stopper can be reduced and the degree of wear of the stopper engaging protrusion and the stopper can be pushed, the product life as a lock-type energy accumulation starter device can be ensured longer.

The thickness of the locking piece 61 is smaller than the interval between the grooves 55 formed in the ratchet pulley 24. When the stopper 21 is disposed in the groove 55, the ratchet pulley 24 has no problem. It is configured to be able to rotate.

On the other hand, in the coil spring 23, an upper folded portion 64 is formed along the length direction at the lower end portion, and a stopper locking portion 65 is similarly formed along the length direction at the upper end portion.
The coil spring 23 is inserted through the cylindrical shaft portion 58, the upper folded portion 64 is inserted into the gap 59 of the rib 90, and the coil spring 23 is fixed in the laterally protruding portion 29. It is formed to be able to.

The stopper 21 is fixed to the upper end portion of the cylindrical shaft portion 58 so as to be turnable in the left-right direction by the screw 25, and is arranged to be movable up and down along the axial direction of the cylindrical shaft portion 58. In a state where the stopper 21 is fixed to the upper end portion of the cylindrical shaft portion 58, the tip end portion of the stopper locking portion 65 of the coil spring 23 is engaged and fixed to the spring locking recess 66.

The coil spring 23 is operated to pull out the recoil rope 12, and the driving force necessary for starting the internal combustion engine to which the lock type energy storage starter device 10 is mounted is accumulated in the energy storage spring 15. Up to this point, it has a spring constant that can supply the stopper 21 with an urging force that can prevent the ratchet pulley 24 from rotating.

Therefore, the stopper 21 is engaged with a stopper engaging protrusion 80 provided in an upper groove 55a described later in a state where the stopper 21 is urged by the coil spring 23 with the urging force.
The groove portion 55 is formed with a dimension equal to or larger than the length dimension corresponding to the number of rotations of the ratchet pulley 24 required until the driving force accumulated by the force accumulation spring 15 is completely released.
In other words, in the energy storage starter device, when the energy storage spring 15 releases the accumulated force by storing energy to generate torque that can drive the engine, the energy accumulation starter 15 is accumulated. The ratchet pulley 24 rotates until the applied force is completely released and the recoil rope 12 returns to the initial state where it can be pulled out again.

In the lock-type energy accumulation starter device 10 according to the present embodiment, the ratchet pulley 24 is configured to return to the initial state by two rotations.
That is, after the stopper 21 is released from the stopper engaging portion 80 provided in the upper groove portion 55a, the stopper 21 is again locked by the stopper engaging portion 80 and stopped by rotating twice. It is configured as follows.

In this case, the accumulator spring 15 according to the present embodiment is formed so as to release the accumulated force in 1.5 revolutions after the accumulated force is released, but the ratchet pulley 24 Since the force accumulated in the force 15 releases the force accumulated in the force accumulation spring 15 and continues to rotate with inertia, the stopper 21 is stopped by the stopper engaging portion in 1.5 rotations. When it is configured to re-engage with 80 and return to the initial state, there is a possibility that the stopper engaging portion 80 may come into contact with the stopper 21 at a high speed due to the rotation with the inertia.

In such a case, it may be assumed that the stopper 21 gets over the stopper engaging protrusion 80, and the operator may need to pull out more recoil ropes 12 during the next operation. . Further, the stopper engaging protrusion 80 or the stopper 21 may be damaged due to the contact with the stopper 21 due to the high speed of the stopper engaging portion 80, and may not function as a lock-type energy accumulation starter device.
Therefore, it is necessary to engage the stopper 21 with the stopper engaging protrusion 80 after the urging force inherent in the energy storage spring 15 is completely released at any operation, and to return to the initial state. It is set so that the ratchet pulley 24 returns to the initial state when the ratchet pulley 24 rotates twice, leaving a margin for 0.5 rotation.

As shown in FIGS. 2 and 6, in the present embodiment, as described above, the groove portion 55 is formed over two upper and lower stages of the upper groove portion 55a and the lower groove portion 55b, and has 10 characters in the middle portion. The crossing portions 56 are crossing each other.
As shown in FIG. 5, a stopper engaging protrusion 80 is formed in the upper groove portion 55 a toward the outer side of the groove portion 55, and the stopper 21 is stopped by the biasing force of the coil spring 23. By engaging with the stopper engaging protrusion 80 while being urged in the 80 direction, the rotation of the ratchet pulley 24 can be prevented until the driving force necessary for starting the engine is accumulated in the accumulating spring 15. It is configured.

As shown in FIGS. 1 and 6, the 10-shaped crossing portion 56 is provided on the diametrically opposite side of the stopper engaging protrusion 80. In the intersecting portion 56, the upper flange portion 67 forming the upper groove portion 55a has an upper guide portion 68 having a substantially triangular side surface projecting into the upper groove portion 55a, and a lower groove portion facing the upper guide portion 68. A lower guide portion 70 formed so as to protrude from the lower flange portion 69 forming the 55b into the lower groove portion 55b is formed.

Further, the intermediate flange portion 71 that defines the upper groove portion 55a and the lower groove portion 55b is cut at a predetermined interval at a portion where the upper guide portion 68 and the lower guide portion 70 are opposed to each other. At both ends, bulging guide portions 72 and 73 formed to be thicker than the thickness dimension of a general intermediate flange portion 71 are formed to face each other in the rotational direction.

The pair of bulging guide portions 72 and 73 are formed in a substantially tear-drop shape on the side surface, and gradually increase in thickness toward the intersecting portion 56 side, and then in a shape that becomes acutely thinner toward the distal end portion. .
As a result, in the 10-shaped crossing portion 56, the oblique sides 74a and 74b of the upper guide portion 68 are the upper inclined portion 75a of the bulging guide portion 72 and the upper inclined portion of the bulging guide portion 73. The oblique side portions 76 a and 76 b of the lower guide portion 70 are formed substantially parallel to the lower inclined portion 77 a of the bulging guide portion 72 and the lower inclined portion 77 b of the bulging guide portion 73.

As a result, the upper groove portion 55a and the lower groove portion 55b are formed at the intersecting portion 56 with a passage formed by the oblique side portion 74a of the upper guide portion 68 and the upper inclined portion 75a of the bulging guide portion 72, and the lower guide portion. A downward movement passage 78 that transitions from the upper groove portion 55 a to the lower groove portion 55 b is formed by a passage formed by the oblique side portion 76 b of 70 and the lower inclined portion 77 b of the bulging guide portion 73.
Further, a passage formed by the oblique side portion 74b of the upper guide portion 68 and the upper inclined portion 75b of the bulging guide portion 73, and the oblique side portion 76a of the lower guide portion 70 and the lower inclined portion 77a of the bulging guide portion 72. Thus, an upward movement passage 79 that transitions from the lower groove portion 55b to the upper groove portion 55a is formed, and the lower movement passage 78 and the upper movement passage 79 intersect with each other.

Therefore, in the lock-type energy accumulation starter device 10 according to the present embodiment, the ratchet pulley by the engagement of the stopper 21 with the stopper engagement protrusion 80 is released by releasing the torque accumulated in the energy accumulation spring 15. 24, when the ratchet pulley 24 is rotated, the locking claw 62 of the stopper 21 moves over the stopper engaging protrusion 80 and relatively moves in the upper groove 55a. At the intersection 56, it enters the lower groove 55b via the downward movement passage 78, moves through the lower groove 55b and makes one round, and again at the intersection 56 from the lower groove 55a by the upward movement passage 79. Returning to the upper groove 55a, the stopper engaging projection 80 is reached, and the stopper 21 is engaged with the stopper engaging projection 80 to return to the initial state of stopping. It is configured to.

Hereinafter, an operation of the lock type energy accumulation starter device 10 according to the present embodiment will be described.
When the internal combustion engine is started using the lock type energy accumulation starter device 10 according to the present embodiment, as a precondition, the locking claw 62 of the stopper 21 of the rotation prevention unit 20 is located above the ratchet pulley 24. The ratchet pulley 24 is fixed by engaging with the stopper engaging protrusion 80 of the groove 55a.
Further, the engaging projection 51 of the ratchet pulley 24 and the pair of ratchets 52 and 52 disposed on the crank pulley 49 are in an engaged state.

Therefore, when the operator pulls out the recoil rope 12 through the handle portion in this state, the one-way clutch 40 constituting the drive side transmission mechanism portion 17 includes the accumulating spring holder 33 and the fixed shaft portion 31. And the accumulator spring holder 33 can rotate around the fixed shaft portion 31 in only one direction. In addition, the engagement mechanism 41 includes the brake spring 83 which does not hold the retainer 42. The retainer 42 is in the non-actuated position as shown in FIG. 3 because it is biased so that it is in the operating state, and the tip 89 of the dog 43 is within the lower end peripheral edge 46 of the accumulating spring holder 33. It is in a state where it is engaged with the protrusion 47 provided on the side surface, and as a result, the drive reel 13 and the accumulator spring holder 33 can be connected and rotated. It made.

Further, in the state where the ratchet pulley 24 is restricted by the stopper 21 so as not to rotate, the drive reel 13 and the energy storage spring holder 33 rotate while the rotation of the ratchet pulley 24 is blocked. The accumulating spring 15 housed therein is wound up, and the accumulating spring 15 is accumulated until reaching an urging force capable of generating a rotational torque of a level necessary for starting the engine.

In this case, at the same time, the recoil spring 11 disposed below the drive reel 13 also stores power in preparation for returning to the initial position when the force stored in the power storage spring 15 is released.
Moreover, in the lock | rock type | mold energy accumulation starter 10 which concerns on this Embodiment, although it is comprised so that required accumulation | storage power may be performed by one pull-out operation of the recoil rope 12, an operator is in the middle. When the return operation of the recoil rope 12 is performed, the accumulator spring holder 33 is stopped at that position by the action of the one-way clutch 40, and the retainer 42 is retracted when the recoil rope 12 is pulled back as shown in FIG. Rotates and the engagement state of the dog 43 with the accumulator spring holder 33 is canceled, so that the connection state between the accumulator spring holder 33 and the drive reel 13 is released, and the drive reel 13 is accumulated in the recoil spring 11. The recoil rope 12 is wound up by being reversed by the driving force.

When the operator completes the accumulation of the rotational torque required for starting the engine by pulling out the recoil rope 12, the stopper 21 is engaged with the stopper engaging protrusion 80 as described above. The spring constant of the coil spring 23 that biases the stopper 21 is set in accordance with the magnitude of the driving force required for starting the internal combustion engine that is started by the lock-type energy accumulation starter 10 according to the present embodiment. Therefore, when the level of the force accumulated in the energy storage spring 15 reaches a level that generates the driving force necessary for starting the internal combustion engine to be started, the driving force accumulated in the energy storage spring 15 is reduced. Overcoming the urging force of the coil spring 23, the engagement of the stopper 21 with the stopper engagement protrusion 80 is released, and the force is accumulated in the force accumulation spring 15. Force is released instantaneously.

In this case, as described above, the outer side end of the energy storage spring 15 is engaged with the engagement fixing portion 37 of the energy storage spring holder 33 and the inner side end of the energy storage spring 15 is the ratchet pulley. 24, the ratchet pulley 24 is instantaneously rotated at a high speed around the fixed shaft 31 by the release of the urging force of the accumulator spring 15. Is transmitted to the crankshaft of the engine via the crank pulley 49 and becomes a driving force for starting the engine.

In the present embodiment, when the ratchet pulley 24 rotates 1.5 times as described above, almost all of the urging force accumulated in the accumulating spring 15 is released, and the accumulating spring 15 has the urging force. Return to no state.
However, as described above, the ratchet pulley 24 continues to rotate with inertia due to the release force of the force accumulated in the accumulator spring 15, so that the stopper engaging portion 80 is still larger due to the inertia rotation. There is also a possibility that it will come into contact with the stopper 21 at a speed. In such a case, the stopper 21 gets over the stopper engaging protrusion 80, and the operator pulls out more recoil ropes 12 at the next operation. May need to be done.
Furthermore, the stopper engaging protrusion 80 or the stopper 21 may be damaged, and may not function as a lock-type energy accumulation starter device.
Therefore, in this embodiment, the initial position, that is, the stopper 21 is engaged with the stopper engaging protrusion 80 and stopped in two rotations.

In this case, with the rotation of the ratchet pulley 24, the engagement claw portion 62 of the stopper 21 disposed in the groove portion 55 is disengaged from the stopper engagement protrusion 80 in the upper groove portion 55a. After that, since it is in the groove 55a and the ratchet pulley 24 rotates, the upper groove 55a is relatively half-circulated to the intersection 56, and the oblique side 74a and the swelling of the upper guide 68 are expanded. Guided by the upper inclined portion 75a of the protruding guide portion 72, the lower inclined portion 77b of the bulging guide portion 73, and the oblique side portion 76b of the lower guide portion 70, and is lowered through a downward movement passage 78 formed therebetween. Enter into the groove 55b.

Thereafter, the lower groove portion 55b goes around once and reaches the intersecting portion 56 again. The oblique side portion 76a of the lower guide portion 70, the lower inclined portion 77a of the bulging guide portion 72, the oblique side portion 74b of the upper guide portion 68, and Guided by the upper inclined portion 75b of the bulging guide portion 73, it returns to the upper groove portion 55a via an upward movement passage 79 formed therebetween.
After that, after making a relatively half turn around the upper groove 55a, the stopper 21 is reengaged with the stopper engaging protrusion 80, so that the ratchet pulley 24 stops rotating.

In this way, when the stopper 21 is reengaged with the stopper engaging protrusion 80 of the ratchet pulley 24 and returns to the initial state, the drive reel 13 is rotated by the stored recoil spring 11 and the recoil rope 12 is Return to the initial position while winding.
Therefore, in this state, the operator can perform a power accumulation work for the next engine start by performing the pull-out operation of the recoil rope 12 again.

In the lock-type energy accumulation starter device 10 according to the present embodiment, the force accumulated in the energy accumulation spring is completely released when the ratchet pulley 24 rotates twice, and the groove portion 55 is configured. However, since it is originally formed with a length of at least 1.5 rotations necessary for releasing the power storage spring in which the driving force is stored, the power storage spring 15 is reliably stored. It is possible to release the generated driving force and prepare for the next power storage.

Therefore, in the lock-type energy accumulation starter device 10 according to the present embodiment, a so-called engagement delay mechanism as in the conventional lock-type energy accumulation starter device becomes unnecessary.

In other words, in the conventional lock-type energy accumulation starter device, in order to release the driving force accumulated in the energy accumulation spring without fail and to engage the stopper with the ratchet pulley, A stopper engagement delay mechanism for urging the stopper in the direction of the ratchet pulley is provided for a predetermined time later, and the stopper is engaged with the ratchet pulley after completion of the operation of the delay mechanism. .
Therefore, in the lock-type energy accumulation starter device 10 according to the present embodiment, there is no need to provide a conventional stopper engagement delay mechanism, and a spring and a support member that constitute a biasing means necessary for this mechanism. Etc. can be omitted, and the number of components as the whole apparatus can be further reduced.

In the present embodiment, the case where the groove portions 55a and 55b are formed in the upper and lower two steps on the side surface portion of the ratchet pulley 24 has been described as an example. However, the present invention is not limited to the above embodiment, and the ratchet pulley 24 It is also possible to change the number of the groove portions 55 by changing the diameter or the thickness dimension. Further, it is possible to form the groove with the optimum length of the groove and the number of grooves corresponding to the engine displacement and engine type to be applied.

In this embodiment, the ratchet pulley 24 is rotated twice so that the upper and lower grooves 55a and 55b are relatively rotated, so that the stopper 21 is engaged with the stopper engaging protrusion 80. The ratchet pulley 24 is configured to release the force accumulated in the accumulator spring 15 at 1.5 revolutions as a precondition, but is not limited to the above embodiment, for example, In addition to forming three grooves along the vertical direction, two stopper engaging protrusions are provided at equal intervals in the groove, and the initial state in which the accumulator spring 15 is released is restored by 1.5 rotations. It can also be configured to be.

Further, as in the present embodiment, two upper and lower grooves 55a and 55b are provided, and two stopper engaging protrusions 80 are provided at equal intervals, so that the force of the accumulating spring 15 is released by one rotation.

When a plurality of stopper engaging protrusions are provided as described above, the stopper engaging protrusions 80 of the stopper 21 due to the rotation of the ratchet pulley 24 at a very high speed when the force accumulated in the force accumulation spring 15 is released. It is possible to reduce the intensive load on the stopper engaging protrusion 80 due to the contact with the lock, and it is possible to ensure a longer product life of the lock-type energy accumulation starter device.

Further, when considering the contact of the stopper 21 with the stopper engaging protrusion 80 due to a large speed, for example, the depth dimension of the groove 55 reaching the stopper engaging protrusion 80 along the rotation direction of the ratchet pulley 24 is set. In addition, a brake portion that can be formed so as to be reduced as it approaches the stopper engaging protrusion 80 and that can brake the rotation of the ratchet pulley 24 can be provided.

  When the brake portion having such a configuration is provided, the contact speed of the stopper 21 to the stopper engaging protrusion 80 due to the high-speed rotation of the ratchet pulley 24 when the force of the power storage spring 15 is released is reduced. Since the impact on the stopper engaging protrusion 80 can be reduced and the degree of wear of the stopper engaging protrusion 80 and the stopper 21 can be pushed in the same manner as described above, the product life as a lock-type energy accumulation starter device can be increased. It can be secured longer.

In the present embodiment, the engaging portion 54 that can prevent the rotation of the ratchet pulley 24 includes the stopper engaging protrusion 80 provided in the groove portion 55a of the ratchet pulley 24, and the stopper engaging protrusion. Although the case where the stopper 80 is engaged with the portion 80 while being biased by the coil spring 23 has been described as an example, for example, the stopper member is provided on the ratchet pulley 24 side, and the engaging protrusion 80 is provided. May be configured to be provided separately from the ratchet pulley 24 on the rotation blocking unit 20 side, but is not limited to the configuration of the present embodiment.

Furthermore, the coil spring 23 as the stopper urging means 22 according to the present embodiment may be a torsion coil spring, a compression spring, or a tension coil spring, and is limited to the type of spring that applies an urging force to the stopper 21. There is no.

In addition, the specific configuration of the rotation prevention unit 20 is not limited to the above embodiment, and the stopper urging means 22 may be an elastic body made of a material such as rubber, for example. The present invention is not limited to the above embodiment as long as it can be given.

Further, in the present embodiment, the case where the ratchets 52, 52 constituting the driven portion side coupling mechanism portion 19 are provided on the crank pulley 49 side is described as an example, but the present embodiment is not limited to this embodiment. The ratchets 52, 52 may be provided on the ratchet pulley 24 side. Thus, when the ratchet pulleys 52 and 52 are provided on the ratchet pulley 24 side, it is necessary to provide the ratchet pulley 52 with a retainer and a brake spring for taking in and out the ratchet 52 and 52 at the same time.
Further, the configuration of the crank pulley 49 has been described by taking the centrifugal type as an example in the present embodiment, but may be a ratchet type or the like, and is not limited to the above embodiment.

Therefore, the handle portion 118 and the accumulator spring holder support portion 129 are fixed by the fixing bolt 122 and are integrally fixed to the resin case 120 so as to be rotatable.
In this embodiment, unlike the above embodiment, the ratchet pulley 24 is rotatably fixed to the accumulator spring holder 33 by a fixing bolt 130.
The fixing bolt 130 is disposed at the center of the resin case 120 on the same axis as the fixing bolt 122.

On the other hand, the handle portion 118 includes a handle stay 123 and a grip 124 that is rotatably fixed to the distal end portion of the handle stay 123.
The handle stay 123 is formed to be foldable in the longitudinal direction by a pin 125 provided in the middle, and the grip 124 is formed in a rod shape and is provided orthogonally at the distal end of the distal end side handle stay 123a. The bolt 126 is provided so as to be rotatable with respect to the handle stay 123.
As a result, the operator can rotate the handle stay 123 by gripping the grip 124, and can store the handle stay 123 folded by the pin 125 when not in use.

Therefore, when the engine starting operation is performed by the lock-type energy accumulation starter device 116 according to the present embodiment, the operator holds the grip 124 of the handle portion 118 and passes through the handle stay 123 in one rotation direction. For example, when rotated clockwise, the rotational driving force is transmitted to the accumulator spring holder 33 through the fixing bolt 122, and the accumulator spring holder 33 has a ratchet pulley by a stopper (not shown). Since it rotates in a state where it cannot be rotated, the energy storage spring 15 housed in the energy storage spring holder 33 is wound up, and the energy storage spring 15 can generate a rotational torque of a level necessary for starting the engine. Accumulate until energizing force.
In this case, since the one-way clutch 119 is provided, even if the operator accidentally loosens the handle operating force during the rotation operation when the operator rotates the handle portion 118 when the engine is started, It is possible to effectively prevent a situation in which the handle portion 118 reverses due to the reaction force of the accumulating spring 15 and the handle portion 118 hits the operator's hand or the like and damages the operator.

When the operator completes the accumulation of the rotational torque required for starting the engine in the accumulator spring holder 33 by the turning operation of the handle portion 118, as described in the above embodiment, The spring constant of the coil spring 23 that urges the stopper 21 so as to engage the stopper 21 with the stopper engaging protrusion 80 is necessary for starting the internal combustion engine in which the lock type energy accumulation starter 10 according to the present embodiment is started. When the level of the force accumulated in the accumulator spring 15 reaches a level that generates the driving force necessary for starting the internal combustion engine to be started, The driving force accumulated in the force accumulation spring 15 overcomes the urging force of the coil spring 23, and the stopper engaging protrusion 80 of the stopper 21. The engagement is released, biasing force accumulated in the accumulating spring 15 is released instantaneously.

In this case, as described above, the outer side end of the energy storage spring 15 is engaged with the engagement fixing portion 37 of the energy storage spring holder 33 and the inner side end of the energy storage spring 15 is the ratchet pulley. 24, the ratchet pulley 24 is instantaneously rotated at a high speed around the fixing bolt 130 by releasing the urging force of the accumulating spring 15, and this rotation is It is transmitted to the crankshaft of the engine via the crank pulley 49 shown in FIG. 1 and becomes a driving force for starting the engine.

In the lock type energy accumulation starter device 116 according to the present embodiment, unlike the lock type energy accumulation starter device 10 according to the embodiment, the recoil spring 11, the recoil rope 12, and the recoil rope 12. There is no drive reel 13 that can be rotated by the pulling operation and can be returned to the initial state by the driving force accumulated in the recoil spring 11 due to the rotation, so that the mechanism can be simplified and the starter device The thickness dimension of 116 can be made small, and reduction in size and weight can be achieved.
In addition, since the operation of pulling out the recoil rope is not necessary, and the engine can be started by rotating the handle portion 118, it is possible to effectively cope with the use situation of the product when the operation of pulling out the recoil rope is difficult. it can.

FIG. 11 shows a fourth embodiment of the lock-type energy accumulation starter device according to the present invention.
The lock-type energy accumulation starter device 134 according to the present embodiment is a modification of the lock-type energy accumulation starter device 116 according to the embodiment, and the basic configuration is common to the lock-type energy accumulation starter device 116. The difference is that the drive-side transmission mechanism 133 has a transmission gear 136 that meshes with the accumulator spring holder 33, and the rotational movement of the handle portion 118 is transmitted via the transmission gear 136. It is only a point transmitted to.

That is, in the lock type energy storage starter device 134 according to the present embodiment, as in the case of the above embodiment, a cylindrical energy storage spring holder support portion 121 is formed inside the central portion of the resin case 120. The rotation support portion 129 of the energy storage spring holder 33 is rotatably supported and fixed in the energy storage spring holder support portion 121 by a fixing bolt 122.
A gear portion 135 is formed at the base end portion of the rotation support portion 129, and the gear portion 135 meshes with a transmission gear 136 disposed on the side.
The transmission gear 136 is formed in a T-shaped side surface, and is formed between a support wall portion 138 formed further inward of the inner wall portion 137 of the resin case 120 and the energy storage spring holder support portion 121. Has been placed.

That is, the transmission gear 136 includes a gear portion 136a that meshes with the gear portion 135 and a support portion 136b that is provided orthogonal to the gear portion 136a. The handle portion 118 is fixed to the support portion 136a of the transmission gear 136 at a hole portion 128 formed in the bottom surface portion 127 of the resin case 120 via a fixing bolt 139 at the base end portion. As a result, the handle portion 118 is fixed to the resin case 120 so as to be integrally rotatable with the transmission gear 136.

Other configurations are the same as those of the lock-type energy accumulation starter device 116 according to the above-described embodiment.
Therefore, in the lock-type energy accumulation starter device 134 according to the present embodiment, when the operator rotates the handle stay 123 via the grip portion 124 in order to start the engine, the fixing bolt The transmission gear 136 rotates through 139, the accumulator spring holder 33 is rotated through the gear portion 135 that meshes with the gear portion 136 a of the transmission gear 136, and the accumulator spring 15 is wound up to store the force. Is.

Since the lock-type energy accumulation starter device 116 according to the embodiment is configured so that the rotation of the handle portion 118 is directly transmitted to the energy accumulation spring holder 33, the spring reaction force of the energy accumulation spring 15 is reduced. In some cases, it is transmitted directly to the handle portion 118, and the operator requires a predetermined force to rotate the handle portion 118.
However, in the lock type energy accumulation starter device 134 according to the present embodiment, the gear portion 135 formed on the transmission gear 136 and the energy accumulation spring holder 33 is used to generate the driving force generated by the rotation of the handle portion 118. Therefore, the transmission ratio of the driving force generated by the rotation operation of the handle portion 118 can be changed by adjusting the gear ratio of the transmission gear 136 and the gear portion 135 as appropriate. Further, the rotational speed of the handle portion required for accumulating the driving force necessary for starting the engine and the reaction force of the accumulating spring when the handle portion 118 is rotated can be adjusted.

As a result, the operator can also start the engine with a smaller rotational operation force than in the case of the lock-type energy accumulation starter device 116 according to the embodiment.
On the other hand, by adjusting the gear ratio between the gear portion 135 of the power storage spring holder 33 and the transmission gear 136, for example, a larger rotational operation force is required, but the power storage required for starting the engine is required. It can also be configured to reduce the number of rotation operations of the handle portion 118.
Accordingly, by appropriately adjusting the gear ratio between the gear portion 135 of the accumulator spring holder 33 and the transmission gear 136, various specifications that match the user's wishes can be realized.

12 to 14 show a fifth embodiment of the lock-type energy accumulation starter device according to the present invention.
In the lock-type energy accumulation starter device 140 according to the present embodiment, the basic configuration is the same as that of the lock-type energy accumulation starter device 10 according to the first embodiment.
Accordingly, the same components as those of the lock type energy accumulation starter device 10 according to the first embodiment are assigned the same reference numerals and the description thereof is omitted.
The difference is that a recoil wire 141 is used instead of the recoil rope 12 used in the drive unit 14 of the lock-type energy accumulation starter device 10 according to the embodiment.

That is, in the present embodiment, the driving unit is rotated by the pulling operation of the recoil spring 11, the recoil wire 141, and the recoil wire 141, and is in an initial state by the driving force accumulated in the recoil spring 11 by the rotation. And a lever portion 142 that is connected to an end of the recoil wire 141 and can wind the recoil wire 141. When the engine is started, the recoil wire 141 rotates the lever portion 142. It is comprised so that it may be pulled by.

The lock type energy accumulation starter device 140 according to the present embodiment is used as a starter of a brush cutter or a blower machine that is used while being carried on the back of an operator.
That is, as shown in FIGS. 13 and 14, the lock-type energy accumulation starter device 140 according to the present embodiment is used, for example, as a starter device for a blower machine 144 used by the user 147 on the back. The blower machine 144 is configured by a blower machine main body 148 and a frame portion 143 formed in a side face L shape to which the blower machine main body 148 is assembled.

The recoil wire 141 extends from the lock-type energy accumulation starter device 140 and is connected and fixed to a lever portion 142 that is rotatably provided on the frame portion 143.
The frame portion 143 includes a rear plate portion 143a and a lower surface plate portion 143b, and the lever portion 142 is provided at a lower portion of the lower surface plate portion 143a of the lower surface plate portion 143b. It is provided so as to protrude to the side.
The lever portion 142 includes a short cylindrical recoil wire winding portion 145 and a lever main body 146 that is fixedly extended to the winding portion 145.
An end portion of the recoil wire 141 is fixed to a winding shaft portion (not shown) that is rotatably fixed to the lower surface plate portion 143b. When the blower machine 144 is operated to start the engine, the lever main body 146 is attached to the winding portion. The recoil wire 141 is wound and pulled by the take-up shaft portion by rotating around the take-up shaft portion.

The winding shaft portion has an appropriate diameter, and in this embodiment, when the lever body 146 is rotated downward by a predetermined angle (for example, about 90 degrees), the blower machine The recoil wire 141 is pulled so that the driving force sufficient to start the engine 144 can be stored in the power storage spring 15.
Accordingly, as shown in FIG. 13, when the operator 147 wears the blower machine 144 fitted with the lock type energy accumulation starter device 140 according to the present embodiment on the back side, the handle portion 142 is When not in operation, it projects forward from the armpit of the operator obliquely upward at an angle of approximately 45 degrees, and the operator grasps the tip of the lever body 146 and pushes it downward by about 90 degrees to As shown, the take-up portion 145 is rotated to take up and pull the recoil wire 141.

When the lever main body 146 is pushed down, the take-up shaft portion is rotated and the recoil wire 141 is taken up, whereby the recoil wire 141 is pulled. As a result, the drive reel 13 is driven to rotate, and the drive-side transmission mechanism portion. When the driving force is transmitted to the accumulating spring holder 33 through 17 and accumulated in the accumulating spring 15, and the driving force of a level necessary for engine start is accumulated, the engagement of the rotation prevention unit 20 is released. Then, when the ratchet pulley 24 is rotated, the crank pulley of the engine of the blower machine main body 148 is rotated.

In this case, when the operator 147 returns the handle stay 146 in the middle of the turning operation, the driving reel 13 is driven by the urging force accumulated in the recoil spring 11 as in the case of the first embodiment. Rotates in the direction opposite to the direction in which the recoil wire 141 is pulled to temporarily wind the recoil wire 141 in preparation for another pull.
Therefore, in the present embodiment, when the engine of the blower machine 144 is started, the operator 147 can start the engine only by pushing down the handle stay 146 that protrudes forward from the back side of the operator 147. Since it becomes possible and there is no need to perform the operation of pulling out the recoil rope, the operator can easily start the engine while carrying the blower machine 144 on the back.

Further, unlike the case of the lock-type energy accumulation starters 116 and 134 according to the third and fourth embodiments, the energy accumulation spring 15 is not directly accumulated by rotating the handle portion 118. Therefore, the engine can be started with a smaller operating force.

15 to 17 show a sixth embodiment of the lock-type energy accumulation starter device according to the present invention.
As shown in FIG. 15, the lock-type energy accumulation starter device 150 according to the present embodiment is used as a starter for an engine of a generator 151 that is installed outdoors on the ground or the like and used for many purposes.
The lock-type energy accumulation starter device 150 is attached to the side surface of the generator main body 152, and the basic configuration is the same as that of the lock-type energy accumulation starter device 10 according to the first embodiment. As shown in FIG. 17, the driving unit 152 is different in that it includes a rack unit 153 and a pinion unit 154.

That is, the drive unit 152 includes a rack unit 153 that is driven along the length direction by the operator, and a pinion unit 154 that meshes with the rack unit 153. The drive-side transmission mechanism unit 155 includes the above-described drive-side transmission mechanism unit 155. When the rack portion 153 moves in a predetermined direction in the length direction, or downward in FIGS. 15 and 17 in the present embodiment, the pinion portion 154 and the energy storing spring are configured to store the force storing spring 15. It is comprised so that the holder 33 may be connected.

As shown in FIG. 15, the generator 151 according to the present embodiment is of a type that is used by being placed on the ground surface, floor surface, or the like.

A starter unit 160 that is disposed on one side and starts the engine main body unit 156, and leg units 164 and 164 provided between the lower ends of the frame units 158 and 158 are provided.

In the present embodiment, as described above, the drive unit 152 of the lock-type energy accumulation starter 150 includes the rack unit 153 and the pinion unit 154.
As shown in FIG. 16, a pinion portion 154 corresponding to the drive reel 13 in the lock type energy accumulation starter device 10 according to the first embodiment is rotatably fixed to the fixed shaft portion 31.
The pinion portion 154 is formed in a substantially convex shape in cross section, and a gear portion 163 is formed in the entire area of the peripheral surface portion of the lower end portion. The gear portion 161 of the rack portion 153 meshes with the gear portion 163. As shown in FIGS. 15 and 17, the rack portion 153 is arranged in the height direction at the side portion of the engine body portion 156.

The rack portion 153 is inserted into a guide bar 166 erected at a right angle to the upper surface portion of the fixed plate 165 connected to the leg portion 164, and is always fixed by a return spring 167 wound around the guide bar 166. The lower end portion is fixed to the kick plate 168 supported while being biased upward, and the upper end portion is disposed in the vicinity of the intermediate portion in the height direction of the fuel tank portion 15, and the pinion portion 154 has teeth in the intermediate portion. They are arranged together.
Further, a stopper 169 protrudes from the upper surface portion of the fixed plate 165 to restrict the kick plate 168 from descending beyond a predetermined movement interval.

Accordingly, when the operator steps on the kick plate 168 against the urging force of the return spring 167, the rack portion 153 is lowered, and the pinion portion 154 engaged with the rack portion 153 is rotated by the rotation of the pinion portion 154. Is transmitted to the force accumulation spring holder 33, the force accumulation spring 15 is rotated in the direction in which it is wound up (in the present embodiment, the counterclockwise direction in FIG. 17).
As shown in FIG. 16, in the present embodiment, the same drive side transmission mechanism 155 as that in the lock-type energy accumulation starter device 10 according to the first embodiment is provided. .

That is, the drive-side transmission mechanism 155 includes the one-way clutch 40 and the engagement mechanism 41. The one-way clutch 40 is formed in a cylindrical shape between the upper shaft insertion portion 97 of the power storage spring holder 33 and the fixed shaft portion 31 and is press-fitted between the power storage spring holder 33 and the fixed shaft portion 31. Can be brought into a pressure contact state when the rack portion 161 is lowered, and can be separated when the rack portion 161 is raised. When the rack portion 161 is lowered, the accumulating spring holder 33 is attached to the fixed shaft portion 31. And can be rotated only in one direction.

The engagement mechanism 41 functions as follows in the present embodiment.
When the rack portion 153 is lowered, the pinion portion 154 and the dog 43 fixed to the pinion portion 154 rotate, but the retainer 42 is stopped by the biasing force generated by the brake spring 83.
When the rotating dog 43 is engaged with the stopped retainer 42, the side face 96 of the dog 43 is in contact with the short arm 93 of the retainer 42 as shown in FIG. The distal end 89 of the dog 43 protrudes from the arm 94 toward the inner peripheral surface of the drive reel 13. In this state, the retainer 42 rotates together with the dog 43 against the urging force of the brake spring 83 and moves to the protrusion 47. Engage.

Therefore, the coupling state between the pinion portion 154 and the energy storage spring holder 33 is formed by the engagement between the tip portion 89 of the dog 43 and the protrusion 47 provided on the inner peripheral surface portion of the pinion portion 154. Power is stored in the power storage spring 15 of the holder 33.
On the other hand, when the rack portion 161 is raised by the return spring 167, the pinion portion 154 rotates in the direction opposite to that when the rack portion 161 is lowered by the urging force of the return spring 167. At this time, the retainer 42 stops rotating in synchronism with the dog 43 by the urging force of the brake spring 83, and enters a stopped state.
In this case, as shown in FIG. 4, the engagement state between the distal end portion 89 of the dog 43 and the protrusion 47 is released and the dog 43 is stored in the long arm 94 of the retainer 42, and then the pinion portion 154. With rotation, the dog holding portion 45 is engaged and fixed to the reel holding arm 95 of the retainer 42.

Therefore, the connection state between the pinion portion 154 and the accumulator spring holder 33 is canceled by releasing the engagement between the dog 43 and the protrusion 47 provided on the inner peripheral surface portion of the drive reel 13.
Therefore, when using the generator 151 equipped with the lock type energy accumulation starter device 150 according to the present embodiment, the generator 151 is installed on the ground or floor, and the operator steps on the kick plate 168. Lower. In this case, the kick plate 168 is lowered against the urging force of the return spring 167, and the rack portion 153 fixed to the kick plate 168 is also lowered.

As a result, the pinion portion 154 engaged with the gear portion 161 of the rack portion 153 via the gear portion 163 rotates counterclockwise in FIG. 17, and the pinion portion 154 and the accumulator force are accumulated by the engagement mechanism 41. Since the spring holder 33 is in a connected state, the rotational driving force of the pinion portion 154 is transmitted to the energy storage spring holder 33 and winds up the energy storage spring 15.
When the accumulating spring 15 reaches the driving force necessary to start the engine, the engagement state of the rotation preventing portion 20 that prevents the rotation of the ratchet pulley 24 is released as described above. The ratchet pulley 24 is rotated by the rotational driving force of the accumulator spring 15 to rotate the crankshaft of the engine and start the engine.

In the lock type energy accumulation starter device 150 according to the present embodiment, the drive unit is configured by the rack unit 153 and the pinion unit 154, and the rack unit 153 is moved by stepping on the kick plate 168 fixed to the rack unit 153. Since it is configured to lower and rotate the pinion 154 and rotate the accumulator spring holder 33 to accumulate energy in the accumulator spring 15, in particular, power generation installed on the ground or floor surface and used When applied to a machine starter, it is not necessary for the operator to bend over when starting the engine and to pull out the recoil rope, and it is only necessary to step on the kick plate 168 with his feet. The operation can be performed.

The accumulator spring holder 173 is transmitted to the accumulator spring holder 173 via the transmission gear portion 185, and the accumulator spring holder 173 rotates in a state where the ratchet pulley is restricted to be unrotatable by a stopper (not shown). The accumulating spring 15 housed therein is wound up, and the accumulating spring 15 is accumulated until reaching an urging force capable of generating a rotational torque of a level necessary for starting the engine.

When accumulation of rotational torque required for engine start is completed, as described in the above embodiment, the level of force accumulated in the accumulator spring 15 is necessary for starting the internal combustion engine to be started. The driving force is generated and the urging force accumulated in the accumulating spring 15 is released instantaneously, and the ratchet pulley rotates instantaneously at a high speed and is transmitted to the engine crankshaft via the crank pulley. This is the driving force that starts the motor.
When the engine starting operation is finished, the motor 182 is stopped by stopping the pressing of the switch.

In the lock type energy accumulation starter device 170 according to the present embodiment, when the operator operates the activation switch, the motor 182 is activated, and the driving force of the motor 182 is transmitted to the energy accumulation spring holder 173. Thus, the starter can be easily operated to start the engine.
Accordingly, since the engine can be started without performing a manual operation such as a recoil rope drawing operation, it is possible to reduce the labor required for the operator's operation when starting the engine.
Furthermore, in the present embodiment, the drive unit is configured by the first drive unit 171 that can be driven manually and the second drive unit 172 that includes the motor 182, so that the motor 182 has a problem such as battery exhaustion. When this occurs, the starter can be operated manually to start the engine.

Further, in the present embodiment, a one-way clutch 193 that can allow rotation in only one direction is provided between the gear shaft portion 188 and the lower gear 189, and therefore, the motor 182 is used to store energy. When the force is applied, the rotational driving force of the motor 182 is transmitted to the lower gear 189, and the lower gear 189 rotates, so that the lower gear 189 and the gear shaft portion 188 are in a locked state. When 188 and the lower gear 189 rotate integrally, the rotational driving force of the motor 182 is transmitted to the accumulator spring holder 173 via the upper gear 190, and the accumulator spring holder 173 rotates to accumulate the accumulator spring 15. Is accumulated.
On the other hand, when accumulating is performed by pulling out the recoil rope 12 with the motor 182 stopped, the accumulating spring holder 173 rotates in the rotation direction in which the accumulating force can be transmitted by the rotation of the drive reel 13, The rotation is transmitted to the gear shaft portion 188 via the upper gear, and the gear shaft portion 188 rotates. However, the rotational driving force of the gear shaft portion 188 is not transmitted to the lower gear 189, and the gear shaft portion 188 Since the lower gear 189 idles, it is possible to eliminate the load caused by the motor 182 provided as the drive unit during manual operation by pulling out the recoil rope.
Therefore, it is possible to realize a light accumulation operation using the recoil rope.
