Housing device

Abstract

A housing device 10 includes a movable pulley unit 20 and a movable pulley holding mechanism. The movable pulley unit 20 is provided so as to be movable relative to the housing 12 in an up-down direction, and is movable among a first position at which a long object is housed within the housing, and a second position at which the long object is pulled out from the housing. Whereas the long object is pulled out from the housing when the movable pulley unit 20 moves upward, the long object is housed in the housing when the movable pulley unit moves downward. Between the first position and the second position, the movable pulley holding mechanism switches between a state where the movable pulley is movable downward and a state where the movable pulley is immovable downward.

1 . A housing device for housing a long object, the housing device comprising a housing, a movable pulley, a first weight, and a movable pulley holding mechanism, wherein
 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, 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, and 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 first weight is separated from the movable pulley when the movable pulley moves between the first position and the third position, and moves together with the movable pulley when the movable pulley moves between the third position and the second position, and   between the first position and the second position, the movable pulley holding mechanism switches between a state where the movable pulley is movable downward and a state where the movable pulley is immovable downward.   
     
     
         2 . The housing device according to  claim 1 , further comprising a fixed pulley which is arranged above the movable pulley and on which the intermediate portion of the long object is wound, wherein
 when the movable pulley moves upward, the fixed pulley rotates in a first direction and the long object is pulled out from the housing, and when the movable pulley moves downward, the fixed pulley rotates in a second direction opposite to the first direction and the long object is housed in the housing, and   the movable pulley holding mechanism does not restrict the fixed pulley from rotating in the first direction, and switches between a state where the fixed pulley is restricted from rotating in the second direction and a state where the fixed pulley is not restricted from rotating in the second direction.   
     
     
         3 . The housing device according to  claim 2 , wherein the movable pulley holding mechanism includes a ratchet gear which is fixed to the fixed pulley and a ratchet pawl which engages with the ratchet gear. 
     
     
         4 . The housing device according to  claim 3 , further comprising a pressing roller which presses the long object against an outer peripheral surface of the fixed pulley, wherein
 the pressing roller rotates in accordance with rotation of the fixed pulley, and stops rotating when the rotation of the fixed pulley stops.   
     
     
         5 . The housing device according to  claim 1 , further comprising a guide which is mounted on the housing and extends in the up-down direction within the housing, wherein
 an engagement portion with which the guide engages is formed in the movable pulley, and the movable pulley moves in the up-down direction while being guided by the guide.   
     
     
         6 . The housing device according to  claim 1 , further comprising a second weight mounted on the movable pulley, wherein
 a center of gravity of the movable pulley in a state where the second weight is mounted thereon is lower than a center of gravity of the movable pulley in a state where the second weight is not mounted thereon.
