  The sliding door runner structure 100 supports the guide roller 2 that travels along the guide rail 1 (see FIG. 3) provided on the upper edge of the door frame W, and is connected to the upper edge of the door plate D. Bracket 3 and an engaged portion 4 provided on the bracket 3, and a catch member 6 that is installed in the guide rail 1 and has an engaging portion 5 that engages with the engaged portion 4.

  The guide rail 1 is made of an aluminum extrusion mold, and includes an upper surface portion 1a, a pair of side surface portions 1b and 1c that hang down integrally from both side edges of the upper surface portion 1a, and the other side surface portion 1c from the lower end of one side surface portion 1b. An L-shaped raceway portion 1d that extends short toward the lower end of the wire and rises short upward at the tip, a first rib 1e that hangs shorter than the inner surface of the upper surface portion 1a, and a shorter horizontal surface than the inner surface of the other side surface portion 1c. It has a small chamber 1g formed diagonally with the raceway portion 1d by the extending second rib 1f. The lower end of the first rib 1e is slightly below the lower surface of the second rib 1f.

  Two guide rollers 2 are provided at positions corresponding to one end and the other end of the upper edge of the door plate D, respectively. The two guide rollers 2 at each end are rotatably supported by the bracket 3 and travel on the track portion 1 d of the guide rail 1.

The unit member 7 fixed to the upper end corner of the door plate D includes a case member 8 and an engagement lock that can be inserted into and locked in the direction along the guide rail 1 with respect to the case member 8 and can be unlocked by an external operation. A member 9 and a spindle block body 10 fixed to the case member 8 by a screw screw 11 are provided.
The bracket 3 is provided so as to extend upward from the spindle block body 10 and cantilever the two guide rollers 2 via a shaft extending in a direction perpendicular to the longitudinal direction of the guide rail 1 at the upper end. To support.

FIG. 4 is a longitudinal sectional view showing an initial state of the work of attaching the catch member 6 to the guide rail 1.
As shown in FIG. 4, the catch member 6 has a through hole 6 a that penetrates in a direction (vertical direction in the drawing) perpendicular to the longitudinal direction of the guide rail 1. The through-hole 6a has a small-diameter portion 6aa into which the fixing screw 12 is screwed in the upper half and a large-diameter portion 6ab into which the head of the fixing screw 12 enters the lower half.

  When the catch member 6 is housed in the guide rail 1, the catch member 6 abuts against the lower surface of the second rib 1f and the inner surface of the one side surface 1c, and the convex portion 6b (see FIG. 3) provided on the upper surface is the first. The ribs 1e and the second ribs 1f are engaged with the step portions, and are accommodated in the guide rail 1 so as to be movable in the longitudinal direction.

FIG. 5 is a plan view showing the relationship between the rotation direction in which the fixing screw 12 is screwed and the direction in which the catch member 6 moves by frictional force when the fixing screw 12 is screwed.
In a state where the catch member 6 is accommodated in the guide rail 1 as shown in FIG. 4, when the fixing screw 12 is screwed into the small diameter portion 6aa of the through hole 6a, the circumferential surface of the fixing screw 12 that has passed through the small diameter portion 6aa. When a part contacts the first rib 1e of the guide rail 1 and the fixing screw 12 is rotated, the catch member 6 moves along the guide rail 1 due to friction between the fixing screw 12 and the first rib 1e. To do. In this way, the position of the catch member 6 in the guide rail 1 can be adjusted. When the fixing screw 12 is screwed in a state where the catch member 6 is pressed at an appropriate position or an obstacle is installed in the traveling direction of the catch member 6, the gap between the fixing screw 12 and the first rib 1e is increased. The fixing screw 12 can be screwed against the friction without moving the catch member 6.

   The advancing direction of the catch member 6 is determined by the positions of the first rib 1 e and the second rib 1 f with respect to the fixing screw 12 and the screw direction of the fixing screw 12. In the present embodiment, as shown in FIG. 3, the first rib 1e is located on the right side of the fixing screw 12 and the second rib 1f is located on the left side of the fixing screw 12 as viewed from the door frame W side. Since the screw 12 is a forward screw, when the catch member 6 is installed at a position close to the door frame W and the fixing screw 12 is rotated, the catch member 6 approaches the door frame W by the above-described action. 2, the catch member 6 is automatically positioned in a state where the catch member 6 is completely in contact with the door frame W, and the fixing screw 12 can be screwed. Therefore, it is not necessary to accurately position the catch member 6 in a state before the fixing screw 12 is rotated. The same effect can be obtained by reversing the positional relationship between the first rib 1e and the second rib 1f and making the fixing screw 12 a reverse screw.

  When the fixing screw 12 is further screwed in from the state shown in FIG. 4, the fixing screw 12 also contacts the second rib 1f. When the fixing screw 12 is rotated while the fixing screw 12 is in contact with the first rib 1e and the second rib 1f, the fixing screw 12 is sandwiched between the first rib 1e and the second rib 1f. Then, it is screwed between the first rib 1e and the second rib 1f while threading both sides. In this state, since the friction between the fixing screw 12 and the first rib 1e and the friction between the fixing screw 12 and the second rib 1f are balanced, the catch member 6 does not move. That is, if the catch member 6 is not obstructed by the door frame W or other obstacles, the catch member 6 is fixed until the fixing screw 12 contacts the first rib 1e until it contacts the second rib 1f. It moves according to the friction between the screw 12 and the first rib 1e, and the fixing screw 12 is positioned at a position in contact with the second rib 1f.

  When the fixing screw 12 is further screwed in, as shown in FIG. 6, the fixing screw 12 comes into contact with the upper inner wall of the guide rail 1, and the catch member 6 is positioned and fixed to the guide rail 1.

  The bracket 3 that supports the guide roller 2 is provided with a protruding engaged portion 4, and the catch member 6 that is positioned and fixed to the guide rail 1 as described above has a bifurcated engagement with the engaged portion 4. A shaped engaging portion 5 is provided. Thereby, the doorplate D will be hold | maintained, if engagement with the to-be-engaged part 4 and the engaging part 5 is performed. Therefore, the door plate D can be held in the open or closed state depending on the position and direction in which the catch member 6 is provided and the direction of the engaged portion 4 provided in the bracket 3 corresponding to the catch member 6.

FIG. 7 is a horizontal cross-sectional view along the line BB in FIG. 6 and shows the relationship between the catch member 6 attached to the guide rail 1 and the door plate D in the open state.
The catch member 6 can realize appropriate engagement when the engaged portion 4 is clamped by the engaging portion 5 by utilizing the adjustment movement at the time of attachment.

  As described above, the catch member 6 is fixed to the guide rail 1 with the fixing screw 12, and the catch member 6 is fixed when the fixing screw 12 is screwed into the through hole 6 a and fixed to the guide rail 1. When 12 is rotated, a part of the peripheral surface of the fixing screw 12 comes into contact with a part of the guide rail 1 and moves along the guide rail 1 by friction, so that the number of parts is small and the catch position can be easily adjusted. And it can be performed finely.

  Then, the mechanism is less affected than the case where the fixing screw 12 is in contact with the inner wall of the guide rail 1, and the degree of freedom in design is increased. Further, by adjusting the elasticity of the guide rail 1, it is possible to cope with variations in the catch member 6 and the fixing screw 12, and the force applied during the adjustment can be reduced.
