Description

  The present invention relates to a post-insertion runner that is detachably attached to a curtain rail.

  When the number of runners is increased or decreased by changing the curtain, etc., the runners are generally attached and removed from the opening at both ends of the curtain rail. However, depending on the installation location of the curtain rail, there is no space in the opening at both ends. There is a post-insertion runner that allows the runner to be attached and detached later without removing the curtain rail itself. Such a post-insertion runner has a wheel portion having a wheel that rolls on the rail surface formed on both sides of the rail groove of the curtain rail, and a vertical through hole, and is inserted into the rail groove so as to be movable in the longitudinal direction. A guide part, a latch part for latching the curtain below the guide part, and a pillar part projecting upward from the latch part. The pillar part rotates around the vertical axis in the through hole of the guide part. It is inserted freely and the upper part is connected to the wheel part, and by rotating around the vertical axis of the pillar part, the wheel part can be inserted into the rail groove parallel to the curtain rail and orthogonal to the curtain rail Thus, the posture can be freely changed to a rolling posture in which the wheel is placed on the rail surface, a storage space communicating with the through hole is provided in the guide portion, and when the wheel portion is in the rolling posture, A locking recess is provided at a position facing the storage space. A stopper having an engaging projection that can be engaged with the mating recess is housed. When the wheel is in a rolling posture, the stopper engages with the engaging recess and locks the column so that it cannot rotate. In some cases, the stopper is provided with an operation portion that is movably supported between a locking position to be released and a release position that is disengaged from the locking recess, and for moving the stopper in the release direction.

  In this type of conventional post-runner, an insertion hole that communicates from the lower end surface to the storage space is formed in the guide portion in the vertical direction toward the operation portion of the stopper, such as a thin and hard wire prepared separately. A saddle member was inserted into the insertion hole from below to push the operating portion of the stopper (for example, Patent Document 1).
