Description

The present invention relates to a trigger structure for a sliding door closer that operates the sliding door closer to draw the sliding door into a door pocket.

Conventionally, a sliding door closer is provided on a sliding door that is suspended from a rail provided on an upper frame of a door pocket. This sliding door closer automatically pulls the sliding door from a position in the door pocket near the door end to an end on the door end side to open it. The sliding door closer pulls the sliding door into the door pocket by engaging a trigger attached to a rail provided on an upper frame inside the door pocket (for example, see Patent Document 1).

Patent Document 1 discloses an inner rail disposed in a door pocket, an outer rail extending from the inner rail toward the door edge, and a sliding door closer provided at the top of the sliding door, the rail being movable. A sliding door closer set is disclosed that includes a trigger and a trigger disposed within the door pocket.

The trigger structure of the sliding door closer described above includes a trigger-integrated plate (trigger plate in the present application) to which the trigger is integrally coupled, and the trigger-integrated plate is inserted into the inner rail from the door edge side and pulled out. A possible guide is provided. This trigger-integrated plate has the trigger coupled to one end in the length direction and a mounting portion for the outer rail provided at the other end. Most of the trigger integral plate is inserted into the guide part of the inner rail. Further, the mounting portion of the trigger integrated plate is inserted into a guide portion of an outer rail located outside the door pocket, and is attached to the outer rail with a fastening member such as a screw.

Japanese Patent Application Publication No. 2016-176331

By the way, when a sliding door is opened and closed vigorously and a large force is continuously applied to the trigger from the sliding door closer, the trigger may be deformed or damaged. In this case, in the trigger structure of the sliding door closer disclosed in Patent Document 1, the fastening members such as screws from the mounting portion of the trigger integrated plate can be removed and the trigger integrated plate can be replaced on the outside of the door pocket.

However, in the trigger structure of the sliding door closer disclosed in Patent Document 1, the trigger integrated plate is not fixed to the inner rail, but is only fixed to the outer rail at the attachment portion of the trigger integrated plate. Therefore, when the sliding door is opened with force and the sliding door closer engages with the trigger, one end side of the trigger-integrated plate jumps up with the trigger. As a result, one end of the trigger integrated plate collides with the upper part of the guide portion of the inner rail, producing a loud collision sound.

At this time, the trigger 21 of the trigger plate 6 is located on the door tail side and protrudes downward. Furthermore, the trigger plate 6 is inserted below the door end side end of the door end side stopper 12. Then, the concave portion 14 on the door end side of the trigger plate 6 is brought into contact with the receiving surface portion 13a of the convex portion 13 of the door end side stopper 12 (see FIG. 10). Note that the door end side stopper 12 may be fixed to the inner rail 8 in advance before construction of the door pocket 2.

Next, the door roller units 10, 10 are placed inside the inner rail 8, and the sliding door 3 is suspended from the inner rail 8. Then, as shown in FIG. 11, the door stopper 15 is inserted from the door end side into the upper groove 4a and the pair of front and rear guide portions 4b of the outer rail 9 at the door end side end. The outer rail 9 in this state is arranged along the upper frame 7, and the end face of the outer rail 9 on the door end side is butted against the end face of the inner rail 8 on the door end side. Then, the door end side stopper 15 is moved toward the door end side. Here, the cross-sectional shape of the base portion 15a of the door end side stopper 15 is the same cross-sectional shape as the upper groove portion 4a of the inner rail 8 and the outer rail 9. Therefore, by inserting the base 15a of the door end side stopper 15 across the upper groove 4a of the outer rail 9 and the upper groove 4a of the inner rail 8, the center of the outer rail 9 with respect to the inner rail 8 can be inserted. It is possible to perform alignment (alignment in the front-rear direction). After the outer rail 9 is centered with respect to the inner rail 8, the outer rail 9 is fixed to the upper frame 7.

Next, the end of the base 15a of the door end stopper 15 is inserted into the upper groove 4a of the inner rail 8 and inserted above the trigger plate 6. Then, the receiving surface portion 15e of the door end side stopper 15 is brought into contact with the recessed portion 14 of the trigger plate 6 on the door end side. In this state, the door end side stopper 15 is attached to the upper frame 7 by passing the screw 23 through the outer rail 9 from below the outer rail 9. Thereafter, a door edge trigger (not shown) is fixed to the outer rail 9. In addition, before attaching the outer rail 9 to the upper frame 7, the door edge side trigger may be attached to the outer rail 9. As described above, the trigger plate 6 is attached to the inner rail 8.

In the embodiment of the present invention, the trigger plate 6 needs to be replaced when the trigger 21 of the trigger plate 6 is damaged due to deterioration over time or due to violent opening and closing of the sliding door 3. The trigger plate 6 is replaced as follows. That is, first, remove the screw 23 of the door end side stopper 15. After the door stopper 15 is completely moved into the outer rail 9 toward the door end, the outer rail 9 is removed from the upper frame 7. Subsequently, the trigger plate 6 is pulled out from the inner rail 8, and a new trigger plate 6 is inserted into the guide portion 4b of the inner rail 8. Thereafter, as described above, the door end side stopper 15 and the outer rail 9 are attached to the upper frame 7. In this way, the trigger plate 6 having the trigger 21 can be easily replaced.

As a result, when the sliding door 3 is opened with force and the sliding door closer 5 is forcefully engaged with the trigger 21, the upward external force acting on the trigger plate 6 along with the trigger 21 on the door bottom side is transferred to the door bottom side. It can be received by the receiving surface portion 13a of the convex portion 13 of the stopper 12. As a result, it is possible to suppress the collision between the door end side end portion of the trigger plate 6 and the upper part of the guide portion 4b of the inner rail 8, and furthermore it is possible to suppress the generation of collision noise.

Further, the door end side stopper 12 presses the trigger plate 6 against the lower part of the guide portion 4b of the inner rail 8 by the protrusion 12b. Due to this pressing, the end of the trigger plate 6 on the door end side is held between the lower part of the guide portion 4b of the inner rail 8 and the end of the door end stopper 12 on the door end side. The upward external force acting on the door end side end of the trigger plate 6 described above can be reliably received by the door end side end of the door end stopper 12.

Furthermore, the door end side stopper 15 presses the trigger plate 6 against the lower part of the guide portion 4b of the inner rail 8 by means of a protrusion 15d. By this pressing, the end of the trigger plate 6 on the door end side is reliably held between the lower part of the guide portion 4b of the inner rail 8 and the end of the base 15a of the door end stopper 15 on the door end side.

Further, the concave portion 14 on the door end side of the trigger plate 6 fits into the receiving surface portion 13a of the convex portion 13 of the door end side stopper 12. Further, the recess 14 on the door end side of the trigger plate 6 fits into the receiving surface portion 15e of the door end side stopper 15. By this fitting, the trigger plate 6 engages with the door end side stopper 12 and the door end side stopper 15 and is positioned in the width direction of the inner rail 8. As a result, the trigger 21 of the trigger plate 6 is positioned, and is reliably captured by the sliding door closer 5 of the sliding door 3 and pulled in.

Further, the tip end of the door end stopper 12 on the door end side forms an inclined surface portion 12c. Since this inclined surface portion 12c is inclined upward toward the door end side, the trigger plate 6 can be smoothly moved below the door end side end portion of the door end side stopper 12.
