Push-Action Slide Case

Abstract

[Object] To provide a push-action slide case having excellent productivity and capable of assuring reliable push-into/eject-out operation of a storage body even for long term use. [Solution] For assembling a storage body 4 , first, a second spring 10 is made abut against a rotator 8 which is already engaged with a positioner 6 , then a shaft 22 is inserted into the storage body 4 from the side of the second spring 10 , and a latch projection 22 a of the shaft 22 is fixed to the storage body 4 by a holding piece 24 . In addition, first springs 5 are attached in cylindrical parts 21 . On the other hand, for a main case body 3 , a ceiling part 3 a as a separate body is first removed from the main case body 3 , then a holding block 13 is fixed into a holding piece 25 at the bottom of the main case body 3 , and elastic pieces 18 are attached to their appropriate positions. Then, the ceiling part 3 a is put back on the main case body 3 to form a box body shape. After completing assembling each of the storage body 4 and the main case body 3 in this way, the storage body 4 is inserted into the main case body 3 through an opening 2 to finish the assembly of the slide case as a whole.

1 . A push-action slide case, comprising: 
 a hollow main case body having an opening on one side thereof;    a storage body slidably placed in the main case body, the storage body adapted to be pushed into the inside of the main case body through the opening toward the other side of the main case body;    a first urging member to constantly push the storage body so that the storage body can be ejected from the main case body;    a cylindrical positioner which is integrally formed on the storage body in a shape protruding in the direction of the push-into operation of the storage body;    a positioning ditch which is formed along the periphery of the positioner;    a cylindrical rotator which is disposed so as to abut against the positioner along the direction of the push-into operation of the storage body in such a manner to be able to perform relative rotation to the positioner;    an engagement projection which is formed along the periphery of the rotator, adapted to be detachably engaged with the positioning ditch to determine an attachment position where the rotator is locked into the positioner by the engagement projection being engaged with the positioning ditch, and then to be disengaged from the positioning ditch by the rotator performing the relative rotation to the positioner;    a second urging member to constantly push the rotator toward the positioner along the direction of the push-into operation of the storage body in order to engage the engagement projection with the positioning ditch to lock the rotator into the positioner at the attachment position;    at least one rotation-generating projection formed on the rotator, adapted to make the rotator perform the relative rotation to the positioner against the urging force of the second urging member; and    a holder which is fixedly attached to the main case body, having a cylindrical inner surface where at least one control projection adapted to work with the rotation-generating projection is formed in order to realize keeping the storage body contained within the main case body against the urging force of the first urging member so as to unlock that state anytime, through the positioner and the rotator which move in accordance with the push-into operation of the storage body,    wherein the control projection has a pair of end faces to define, on the cylindrical inner surface, a guide passage which guides the rotation-generating projection from an entrance to an exit along the direction of the push-into operation of the storage body;    on either one of the two end faces, at the entrance of the guide passage, there is formed a first abutting face which leads, into the guide passage, the rotation-generating projection which moves from the entrance of the guide passage to the exit according to the push-into operation of the storage body, pushing the rotation-generating projection for the rotator to perform the relative rotation in a normal direction against the urging force of the second urging member;    at the exit of the guide passage, there is formed a latch ditch with which the rotation-generating projection is locked against the urging force of the second urging member after passing through the guide passage from the entrance to the exit, and from which the rotation-generating projection is unlocked in response to further push-into operation of the storage body; and    on the other out of the two end faces, at the exit of the guide passage, there is formed a second abutting face which guides, into the guide passage, the rotation-generating projection which receives the urging force of the first urging member and goes through the guide passage from the exit to the entrance after being unlocked from the latch ditch, pushing the rotation-generating projection for the rotator to perform the relative rotation in the reverse direction against the urging force of the second urging member.
