Description

[Detailed description of the invention] [Industrial field of application] The invention includes a linear horizontal guide groove and a retraction guide groove that intersects with the linear horizontal guide groove, and is guided by these grooves when the door is opened. This invention relates to a runner for a sliding door device that is slidable and flush when closed.

[Conventional technology]

Conventionally, for this type of sliding door device,
As shown in Japanese Unexamined Patent Publication No. 57-9975, a retraction guide groove is provided diagonally intersecting a linear horizontal guide groove.

Furthermore, it is known that the rail member having the horizontal guide groove and the retracting guide groove is divided into parts according to U.S. Pat.
-Disclosed in Publication No. 55170.

[The problem that the idea aims to solve]

According to the above-mentioned guide groove structure, when being drawn into the guide groove diagonally from the straight line of the horizontal guide groove,
Since the left and right ends of the runner base, that is, the leading ends in the running direction, run in a curved manner while contacting the outer surface of the guide groove, unreasonable conditions such as squeaks occur. In the suspended slide structure using runners, the above-mentioned squeaking and the like were even more severe.

In particular, as each member having these guide grooves is assembled, a step is likely to occur at the joint, and as the runner comes into contact with this step, wobbling occurs.
There was a drawback that smooth running could not be achieved.

Therefore, the present invention has been devised in view of the above-mentioned circumstances, and allows for easy orientation even with respect to the diagonal guide groove of a sliding door, and allows smooth movement over the assembly steps of the guide groove. The purpose of the present invention is to provide a runner that has the following characteristics.

[Means to solve the problem]

A runner of a sliding door device according to the present invention to achieve the above object includes a column-shaped base;
A pair of rollers installed oppositely on both sides of the base,
a hanging bolt rotatably hung downward from the base; a guide pin protruding upward from the top surface of the base and guided in the pin guide groove;
The base is characterized in that the left and right end surfaces thereof are provided with tapered surfaces that are integrally projected toward the left and right running direction to be larger than the diameter of the roller and the left and right width of the guide pin.

[Effect of invention]

A plurality of runners are attached to the upper end surface of the door of the sliding door device and are located within the guide groove.

When the door is opened and closed, the runner runs on the rail surface by the rollers, but the runner runs on the rail surface with the help of the tapered surface that protrudes beyond the rollers against the diagonal guide groove.
It runs without coming into contact with the outer surface of the guide groove.
With respect to the assembly step at the joint portion, the tapered surface comes into contact with the roller and the guide pin first.

[Effect of idea]

As explained above, the present invention has the following effects.

When the runner is guided diagonally from the straight line of the horizontal guide groove into the guide groove, the runner is guided smoothly without colliding with the outer surface of the guide groove due to the tapered surface that protrudes beyond the rollers, and when it comes into contact with the outer surface of the guide groove. The roller can be guided as a guide surface even if In particular, when the guide member is assembled in parts and there is a step at the joint, the tapered surface that protrudes more in the running direction than the roller and guide pin can be brought into contact with the step first to absorb the difference along the tapered surface. can be done. At that time, even if there is a step in the pin guide groove, the guide pin does not pass through first, but the tapered surface of the base always leads the way and passes after correcting the trajectory, so the runner can move smoothly against the joint. can be passed through.
