Definitions

  • the technology disclosed in the present specification relates to a housing device which houses a long object (e.g., a charging cable, an electrical cord, a hose, etc.).
  • a long object e.g., a charging cable, an electrical cord, a hose, etc.
  • a housing device which houses a long object such as an electrical cord has been developed (e.g., Japanese Patent Application Publication No. 2010-52861).
  • the housing device in Japanese Patent Application Publication No. 2010-52861 includes a drum mounted rotatably to a housing, and an electrical cord is wound on an outer peripheral surface of the drum. The electrical cord is pulled out from the drum by a required length when being used, and is wound up after being used.
  • the configuration in which the drum is biased in the winding-up direction by the spring has a problem that as the length by which the long object is pulled out is lengthened, the operating force of an operator for pulling out the long object is increased to be excessively great.
  • the spring constant of the spring which biases the drum is decreased in order to solve this problem, it is possible to prevent the operating force of the operator from becoming excessively great.
  • the spring constant of the spring which biases the drum is decreased, the elastic energy stored in the spring is reduced and thus the force biasing the drum in the winding-up direction is reduced. Thus, a situation occurs where it is impossible to stably wind up the long object on the drum.
  • An object of the present specification is to provide a housing device which is able to prevent an operating force for pulling out a long object from becoming excessively great and which is able to stably house the pulled-out long object therein.
  • a cord housing device disclosed in the present specification is a housing device for housing a long object and includes a housing, a movable pulley, an operating force adjustment mechanism, and a guide mechanism.
  • An intermediate portion of the long object is wound on the movable pulley, the movable pulley is provided so as to be movable relative to the housing in an up-down direction while being guided by the guide mechanism, and the movable pulley is movable among a first position at which the long object is housed within the housing, a second position at which the long object is pulled out from the housing, and a third position which is set between the first position and the second position.
  • the long object housed within the housing is pulled out from the housing when the movable pulley moves upward from the first position toward the second position.
  • the long object pulled out from the housing is housed in the housing when the movable pulley moves downward from the second position toward the first position.
  • the operating force adjustment mechanism generates a first biasing force biasing the movable pulley toward the first position when the movable pulley moves between the first position and the third position, and generates a second biasing force biasing the movable pulley toward the third position when the movable pulley moves between the third position and the second position.
  • the second biasing force is greater than the first biasing force.
  • the “first biasing force” generated by the operating force adjustment mechanism may be any value as long as it is smaller than the “second biasing force”. Therefore, the “first biasing force” may be “0”. In this case, the operating force adjustment mechanism generates the “first biasing force” that is “0”.
  • the housing device is switched between a state where the long object is housed within the housing and a state where the long object is pulled out from the housing, by the movable pulley moving relative to the housing in the up-down direction while being guided by the guide mechanism. If the weight of the long object, a frictional force applied to the long object, and the like are neglected, a force for moving the movable pulley upward is a value determined by the weight of the movable pulley and the “first biasing force” generated by the operating force adjustment mechanism when the movable pulley moves between the first position and the third position, and is a value determined by the weight of the movable pulley and the “second biasing force” generated by the operating force adjustment mechanism when the movable pulley moves between the third position and the second position.
  • the movable pulley and the “biasing force” generated by the operating force adjustment mechanism are adjustable, and thus it is possible to prevent an operating force for pulling out the long object from becoming excessively great.
  • a force required in order to house the long object in the housing is great when the length of the long object that has been pulled out from the housing is long, and is small when the length of the long object that has been pulled out from the housing is short.
  • the force for housing the long object in the housing is made constant and is set to have an appropriate magnitude when the length of the long object that has been pulled out from the housing is long, the force becomes excessively great when the length of the long object that has been pulled out from the housing is short.
  • the force for housing the long object in the housing is made constant and is set to have an appropriate magnitude when the length of the long object that has been pulled out from the housing is short, the force becomes excessively small when the length of the long object that has been pulled out from the housing is long.
  • the force for housing the long object in the housing is a value determined by the weight of the movable pulley and the “second biasing force” generated by the operating force adjustment mechanism when the movable pulley moves between the second position and the third position, and is a value determined by the weight of the movable pulley and the “first biasing force” generated by the operating force adjustment mechanism when the movable pulley moves between the third position and the first position.
  • the “second biasing force” is a value greater than the “first biasing force”
  • the force when the length of the long object that has been pulled out from the housing is long, the force is at a value (a large value) determined by the weight of the movable pulley and the “second biasing force”, and when the length of the long object that has been pulled out from the housing is short, the force is at a value (a small value) determined by the weight of the movable pulley and the “first biasing force”. Therefore, it is possible to stably house the long object in the housing with an appropriate force.
  • the “up-down direction” in which the movable pulley moves may be such a direction that the movable pulley that has moved upward is movable downward due to its own weight.
  • the movable pulley may move obliquely with respect to the vertical direction.
  • the operating force adjustment mechanism may include a first weight.
  • the first weight may be separated from the movable pulley when the movable pulley moves between the first position and the third position, and may move together with the movable pulley when the movable pulley moves between the third position and the second position.
  • the first biasing force generated by the operating force adjustment mechanism is “0”, and when the movable pulley moves between the third position and the second position, the second biasing force generated by the operating force adjustment mechanism is a value determined by the weight of the first weight.
  • the use of the weight allows adjustment of the operating force for pulling out the long object from the housing and the force for housing the long object in the housing.
  • the operating force adjustment mechanism may include a spring.
  • the spring may remain unchanged with its spring length being a free length when the movable pulley moves between the first position and the third position, and the spring length of the spring may be shortened in accordance with a position of the movable pulley and the spring may bias the movable pulley toward the third position when the movable pulley moves between the third position and the second position.
  • the length of the spring is its free length, and thus a restoring force (i.e., the first biasing force) applied from the spring to the movable pulley is “0”.
  • the length of the spring is shortened iii accordance with the position of the movable pulley.
  • a restoring force (the second biasing force) corresponding to the position of the movable pulley is applied from the spring to the movable pulley.
  • the use of the spring allows adjustment of the operating force for pulling out the long object from the housing and the force for housing the long object in the housing.
  • the use of the spring allows such adjustment that the force biasing the movable pulley is gradually increased or decreased. Thus, it is possible to smoothly pull out the long object and house the long object.
  • the guide mechanism may include a guide which is mounted on the housing and extends in the up-down direction within the housing.
  • An engagement portion which engages with the guide may be formed in the movable pulley, and the movable pulley may move in the up-down direction while being guided by the guide. According to such a configuration, the movable pulley is guided by the guide, and thus the mechanism which guides the movable pulley is allowed to have a simple configuration.
  • the guide may include a support portion which supports the first weight.
  • the first weight when the movable pulley moves between the first position and the third position, the first weight may be supported by the support portion of the guide, and when the movable pulley moves between the third position and the second position, the first weight may be separated from the support portion of the guide and may move together with the movable pulley.
  • the guide mechanism which guides the movable pulley allows the first weight to move together with the movable pulley and be separated from the movable pulley.
  • the guide mechanism may include two guides which are mounted on the housing, extend in the up-down direction within the housing, and are provided at both sides in a direction of a rotation axis of the movable pulley, respectively.
  • a first engagement portion which engages with one of the two guides and a second engagement portion which engages with the other of the two guides may be formed in the movable pulley.
  • both sides in the direction of the rotation axis of the movable pulley are guided by the guides, respectively, and thus it is possible to smoothly move the movable pulley in the up-down direction.
  • one of the two guides and one of the two engagement portions may be offset toward one side in a direction orthogonal to the rotation axis of the movable pulley and orthogonal to a direction of gravity, and the other of the two guides and the other of the two engagement portions may be offset toward another side in the direction orthogonal to the rotation axis of the movable pulley and orthogonal to the direction of gravity. According to such a configuration, frictional forces produced between the movable pulley and the guides are reduced, and it is possible to more smoothly move the movable pulley in the up-down direction.
  • the guide mechanism may include two guides which are mounted on the housing, extend in the up-down direction within the housing, and are provided at one side in a direction of a rotation axis of the movable pulley.
  • a first engagement portion which engages with one of the two guides and a second engagement portion which engages with the other of the two guides may be formed in the movable pulley.
  • guides and engagement portions may not be provided at the other side in the direction of the rotation axis of the movable pulley.
  • the guide mechanism may include two guides which are mounted on the housing, extend in the up-down direction within the housing, and are provided at both sides, respectively, in a direction orthogonal to a rotation axis of the movable pulley and orthogonal to a direction of gravity.
  • a first engagement portion which engages with one of the two guides and a second engagement portion which engages with the other of the two guides may be formed in the movable pulley.
  • one of the two guides and one of the two engagement portions may be offset toward one side in a direction of a rotation axis of the movable pulley, and the other of the two guides and the other of the two engagement portions may be offset toward another side in the direction of the rotation axis of the movable pulley. According to such a configuration, frictional forces produced between the movable pulley and the guides are reduced, and it is possible to more smoothly move the movable pulley in the up-down direction.
  • Each housing device described above may further include a second weight.
  • the movable pulley may be movable to a fourth position which is set between the third position and the second position.
  • the movable pulley may be separated from the first weight and the second weight.
  • the movable pulley moves between the third position and the fourth position, the movable pulley and the first weight may move together, but the movable pulley and the second weight may be separated from each other.
  • the movable pulley moves between the fourth position and the second position, the movable pulley, the first weight, and the second weight may move together.
  • the operating force for pulling out the long object is adjusted at three levels, and the force for housing the long object in the housing is also adjusted at three levels.
