2. Description of the Related Art A traveling runner has been proposed in which a moving partition is hung from a hanger rail and moved so that the moving partition can smoothly pass through an intersection of the hanger rail (Japanese Patent Laid-Open No. 59-145879).

[0003] This is constituted by attaching four disk-shaped guide plates to the upper surface of a runner body having two-way running rollers. Each guide plate is arranged in a square shape,
The guide spaces are spaced apart from each other by a predetermined pitch to form a cross-shaped guide space therebetween. Further, a cross-shaped mounting base separate from the hanger rail is interposed at the intersection of the hanger rails, and a guide member that engages with the guide plate of the runner body is provided downward on the lower surface of the mounting base. Therefore, the runner runs at the intersection of the hanger rails,
By engaging each guide plate with the guide member, it is possible to smoothly go straight through the intersection of the hanger rail and pass therethrough. By temporarily stopping and positioning at the center of the intersection, it can be moved in any direction. They can be moved in different directions. The traveling runner is stable through the guide member even when the traveling roller separates from the traveling surface of the hanger rail by the guide member relatively entering the guide space and each guide plate being uniformly engaged with the guide member. It is because it can support.

[0004]

According to the prior art, the traveling runner is moved by the guide plates at the intersection of the hanger rails unless the guide members are accurately positioned at the center of the guide space between the guide plates. Is limited to the straight ahead direction, so when changing the traveling direction,
It is necessary to correctly position and stop at the center of the intersection, and there is a problem that the moving operation of the moving partition is difficult. In addition, since a dedicated mounting base is used at the intersection of the hanger rails, the structure of the intersection is complicated, and there is a problem that assembly is troublesome.

Therefore, an object of the present invention is to provide a sliding member attached to a runner body in view of the above-mentioned problems in the prior art, so that even when the traveling direction is changed in an arbitrary direction, the runner body is provided at the intersection of the hanger rail. It is an object of the present invention to provide a traveling partition runner in which it is not necessary to temporarily stop the runner main body, the operation of moving the partition is extremely simple, and the structure of the intersection can be simplified.

According to the structure of the present invention, the runner main body can travel through the traveling roller at the straight portion of the hanger rail, and can slide through the sliding member at the intersection of the hanger rail. . Therefore, the runner body does not need to position specific members in an exact relative relationship at the intersection of the hanger rails, and even when changing the traveling direction, it does not stop temporarily and continuously and smoothly. Can be moved. The sliding member has a lower surface that slides on the running surface of the hanger rail slightly higher than the running roller. In order to minimize the friction on the running surface, the sliding member is made of, for example, a duracon containing molybdenum. It is preferable to use a low-friction resin material having abrasion.

When the sliding member is provided with a guide roller,
The guide roller can guide the runner main body through the opening of the hanger rail, and can stably move the runner main body in the traveling direction without providing a guide rib or the like on the hanger rail.

A plurality of sets of guide rollers provided for each direction in which the traveling rollers are disposed, each of which simultaneously contacts the wall surface of the opening of the hanger rail to prevent the runner main body from inadvertently rotating horizontally. The main body can be moved more stably.

[0013] If a cross-shaped guide groove is formed on the upper surface of the runner body via a plurality of engagement protrusions, the engagement roller provided at the intersection of the hanger rail relatively enters the guide groove. By doing so, it is possible to prevent the runner main body from inadvertently rotating horizontally and to appropriately guide the traveling direction of the runner main body via the guide grooves.

When the guide surface is formed on the top of the engaging projection, the guide surface appropriately guides the runner body by engaging the engaging roller when the runner body changes the traveling direction, and Horizontal rotation can be minimized.

In the sliding member having the auxiliary guide portions at the respective corners, the entire portion including the auxiliary guide portions slides on the running surface at the intersection of the hanger rails, and there is no possibility that the sliding member comes off the running surface.

If the lower surface of the sliding member is formed into a smooth curved surface, the traveling runner can smoothly transition between the traveling state by the traveling roller and the sliding state by the sliding member.
There is no danger of damaging impacts during the transition.
