Definitions
- the technique disclosed in this specification relates to a storage device that stores a long object (for example, a charging cable, an electric cord, a hose, or the like).
- a long object for example, a charging cable, an electric cord, a hose, or the like.
- JP 2010-52861 A An accommodation apparatus for accommodating a long object such as an electric cord has been developed (for example, JP 2010-52861 A).
- the accommodation device disclosed in Japanese Patent Application Laid-Open No. 2010-52861 has a drum rotatably attached to a casing, and an electric cord is wound around the outer peripheral surface of the drum. The electric cord is drawn from the drum by a length necessary for use, and is wound around the drum after use.
- the cord storage device disclosed in this specification is a storage device that stores a long object, and includes a housing, a moving pulley, an operation force adjustment mechanism, and a guide mechanism.
- the movable pulley is wound around an intermediate portion of a long object, and is guided by a guide mechanism with respect to the housing so as to be movable in the vertical direction, and a first position where the long object is accommodated in the housing; It is possible to move to a second position where the long object is pulled out from the housing, and a third position set between the first position and the second position.
- the movable pulley moves upward from the first position toward the second position, the long object accommodated in the housing is pulled out from the housing.
- the operating force adjusting mechanism when the movable pulley moves downward from the second position toward the first position, the long object drawn from the housing is accommodated in the housing.
- the operating force adjusting mechanism generates a first urging force that urges the moving pulley toward the first position when the moving pulley moves between the first position and the third position, and the moving pulley is in the third position.
- a second urging force for urging the movable pulley toward the third position is generated.
- the second urging force is larger than the first urging force.
- the “first urging force” generated by the operating force adjusting mechanism may be any value as long as it is smaller than the “second urging force”. Therefore, the “first urging force” may be “0”, and in this case, the operating force adjustment mechanism generates the “first urging force” of “0”.
- the movable pulley is guided by the guide mechanism relative to the housing and moved in the vertical direction, so that a long object is accommodated in the housing and a long object is drawn from the housing. Switched. If the moving pulley moves between the first position and the third position if the weight of the long object or the frictional force acting on the long object is ignored, the moving pulley moves upward. The value determined by the “first urging force” generated by the mass and operating force adjustment mechanism of the moving pulley, and when the moving pulley moves from the third position to the second position, the moving pulley mass and the operating force adjustment mechanism are generated. The value is determined by the “second urging force”. Since the “urging force” generated by the moving pulley and the operation force adjusting mechanism can be adjusted, it is possible to prevent an excessive operation force for pulling out a long object.
- the force required to accommodate the long object in the housing is large when the length of the long object drawn from the housing is long, and when the length of the long object drawn from the housing is short. Get smaller. For this reason, if the force for accommodating the long object in the housing is constant and the length of the long object drawn from the housing is set to an appropriate size when the length is long, the long object is drawn from the housing. When the length of a long object is short, the force becomes too large. On the other hand, if the force for accommodating the long object in the housing is constant and the length of the long object drawn from the housing is set to be an appropriate size when the length is short, the long object is drawn from the housing. When the length of a long object is long, the force becomes too small.
- the force for housing the long object in the housing is generated by the mass of the movable pulley and the operation force adjusting mechanism when the movable pulley moves between the second position and the third position.
- the value is determined by the “urging force”.
- the value is determined by the mass of the moving pulley and the “first urging force” generated by the operation force adjusting mechanism.
- the “second urging force” is larger than the “first urging force”, when the length of the long object drawn from the housing is long, the mass of the movable pulley and the “second urging force” When the length of the long object drawn from the housing is short, the value is determined by the mass of the movable pulley and the “first biasing force” (small value). Therefore, a long object can be stably accommodated in the housing with an appropriate force.
- the “vertical direction” in which the moving pulley moves may be a direction in which the moving pulley moved upward can move downward under its own weight. For this reason, not only when the moving pulley moves in the vertical direction, for example, the moving pulley may move obliquely with respect to the vertical direction.
- the operating force adjustment mechanism may have a first weight.
- the first weight is separated from the moving pulley when the moving pulley moves between the first position and the third position, and the moving pulley moves between the third position and the second position. When doing so, it may move together with the moving pulley.
- the first biasing force generated by the operating force adjusting mechanism is “0”, and the moving pulley is moved to the third position.
- the second urging force generated by the operating force adjusting mechanism is a value determined by the mass of the first weight.
- the operating force adjustment mechanism may have a spring.
- the spring length when the moving pulley moves between the first position and the third position, the spring length does not change in the free length, and the spring moves between the third position and the second position.
- the spring length When moving, the spring length may be shortened according to the position of the moving pulley, and the moving pulley may be biased toward the third position.
- a restoring force that is, the first biasing force acting on the moving pulley from the spring. ) Becomes “0”.
- the spring length is shortened according to the position of the moving pulley, and as a result, the restoring force (second attached) according to the position of the moving pulley. Force) acts on the moving pulley from the spring.
- the spring By using the spring, it is possible to adjust the operating force when pulling out the long object from the housing and the force for accommodating the long object in the housing. Moreover, it can adjust so that the force which urges
