One embodiment provides a recoil starter for starting an engine. The recoil starter includes: a starter case having a storage portion; a rope reel rotatably accommodated in the storage portion, a recoil rope being wound on the rope reel; a recoil spring interposed between the rope reel and the starter case within the storage portion; a cam portion rotatable concentrically with the rope reel and engageable with the engine; and a dust cover provided on an opening of the storage portion to cover the rope reel. The rope reel has concentric circular uneven portions formed on a surface thereof facing the engine, and the dust cover also has concentric circular uneven portions. Therefore, the circular uneven portions of the rope reel and the circular uneven portions of the dust cover fit with each other to provide a nest structure.

Recoil starter

One of the embodiments provides a starter including: a starter case; a rotational torque applying unit; a torque-accumulation spring; a rotating member; a driving pulley; and a rotation regulating mechanism including: a regulating ratchet provided on the driving pulley or the rotating member at a position shifted from a rotation center thereof; and a pressing unit provided on the starter case and urged by a given resilient pressing force to be engaged with the regulating ratchet, wherein, when the rotational torque accumulated in the torque-accumulation spring exceeds the given resilient pressing force, the driving pulley or the rotating member urges back the pressing unit via the regulating ratchet so that the regulating ratchet is disengaged from the pressing unit, to thereby release the rotational torque.

A recoil starter includes a case; a reel pivot formed on the case; a rope reel rotatably supported on the reel pivot; a recoil spring; a cam; a power storage spring interposed between the rope reel and the cam; and a power storage ratchet mechanism disposed between facing surfaces of the rope reel and the cam and. The power storage ratchet mechanism is configured to disengage the rope reel and the cam when the rope reel rotates in an engine-starting direction, and engage the rope reel and the cam when the rope reel rotates in an opposite direction to the engine-starting direction.

According to an aspect of the present invention, there is provided a recoil starter including: a case having a reel supporting shaft; a rope reel having: a tubular shaft portion; an engaging portion; a rope housing groove to house a recoil rope; and a spring housing portion to house a spiral spring; a ratchet axially-slidably arranged outside the tubular shaft portion; a ratchet guide attached to an end of the reel supporting shaft; and a return spring provided between the ratchet guide and the ratchet, wherein an inclined surface and a locking surface are formed on the engaging portion to be engageable with the ratchet, and wherein the inclined surface guides the ratchet toward to be engaged with the driving pulley, thereby rotating the driving pulley and starting the engine, when the rope reel is rotated.

A drive pulley is formed in a cup-like shape one end side of which is integrally formed with a peripheral wall in a cylindrical shape, the peripheral wall in the cylindrical shape of the drive pulley is formed with openings to be engaged with a ratchet member at intervals of 90 degrees along a circumferential direction, an engaging face for engaging with the ratchet member is formed at a side edge of each for the openings directed in an engine starting direction, and a side edge opened substantially orthogonal to the engaging face or by an angle equal to or larger than 90 degrees is formed at a side edge of the opening on an opposed side opposed to the engaging face.

A recoil starter is disclosed which enables a ratchet member to be manufactured at a reduced cost and which is capable of obtaining a sufficient strength and reducing a size and weight thereof without increasing a thickness of a rope reel and the like. The ratchet members are mounted on the rope reel so as to engage with a control member that is rotatably attached to a reel shaft with a rotational resistance imparted thereto, so that the ratchet members are turned radially outwardly to engage with a drive pulley, to thereby allow the drive pulley to rotate integrally with the rope reel. The ratchet members are each formed of a rod material having a circular section by bending the material and are each pivotally supported on a side surface of the rope reel.

A recoil starter having a driving member and a driven member, wherein the driving member further includes recoiling unidirectional rotating means. The recoiling unidirectional rotating means includes a movable locking claw member which is supported by one of the rope reel and the interlocking rotor in such a manner that it is rotatable therewith and movable in a direction along the rotational axis thereof, an urging member for urging the movable locking claw member toward the other of the rope reel and the interlocking rotor, and an engaging member mounted on the other of the rope reel and the interlocking rotor. The unidirectional rotating means is constructed in such a manner that, when the rope reel is rotated in the driving direction, the movable locking claw member is caused to contact and engage with the engaging member to thereby enable the rotation of the rope reel to be transmitted to the interlocking rotor, and that, when the rope reel is rotated reversibly to the driving direction relative to the interlocking rotor, the engagement between the movable locking claw member and the engaging member is released.

A recoil starter has a starter case provided around a starter shaft. A one-way clutch mechanism is formed between one end of the starter shaft and an engine. A reel is mounted rotatably on the starter shaft and a rope is wound in a groove of the reel. A first spiral spring has its ends fixed respectively to the starter case and reel and urges the reel in the direction in which the rope is taken up. A second spiral spring has its ends fixed respectively to the reel and transmits a rotational force of the reel to the starter shaft when the rope is drawn out. The peak load at the engine starting time is absorbed in the second spiral spring.

A recoil starter wherein unidirectional rotating means is enabled to sustain a larger magnitude of torque, obviating the employment of parts which are high in mechanical strength, in rigidity and in working precision, thus making it possible to reduce the weight and the manufacturing cost thereof. The recoil starter includes a driving member, a driven member, and buffering/power-accumulating means interposed between the driving member and the driven member. The buffering/power-accumulating means is enabled, during the driving process, to accumulate the power supplied through the driving process while alleviating impact to the driven member. The accumulated power is subsequently employed to drive the driven member. The recoil starter includes a spiral spring mechanism having a housing adjacent to the driving member, an actuating pulley adjacent to the driven member, a buffering/power-accumulating member interposed between the housing and the actuating pulley, and unidirectional rotating means for permitting rotation of the housing unidirectionally in a driving direction, where the unidirectional rotating means is disposed on the outer peripheral side of the spring housing.

Starter

There is provided a recoil starter for starting an internal combustion engine which has a simple and compact structure with a reduced number of parts and which can be manufactured at a reduced cost. In a recoil starter wherein a shaft portion 2' having a reel 3' rotatably attached thereto is provided on a starter case 1 and wherein a rope 4 wound around the reel 3' by a restoring force of a spring 5 is drawn out to rotate the reel 3' thereby driving a pulley 31 to start an internal combustion engine, a configuration is employed wherein a frictional resistance means is provided on the shaft portion 2'; one end of an arm 28 assembled with frictional resistance against the rotation of the reel 3' is anchored or press-fitted to the friction resistance means with another end thereof engaged with a guide groove 27 on the reel 3'; and the rotation of the reel 3' causes the other end of the arm 28 to move in the guide groove 27 for a swinging motion which causes the arm 28 to be engaged with a notch 32 on the pulley 31. This allows the number of parts to be reduced to achieve a reduced overall size and allows manufacturing cost to be reduced.
