  FIG. 3 shows the bounce suppression device 30 to which the runner member 50 is attached in this embodiment, FIG. 4 schematically shows the configuration of the door plate attachment member 31 in the bounce suppression device 30, and FIG. FIG. 6 schematically shows the configuration of the damper member 32 in the jumping suppression device 30 in the present embodiment, and FIG. 7 shows the damper cap of the damper member 32. The structure of the member 33 is shown in detail.

  As shown in FIGS. 3 to 5, the door plate attachment member 31 includes a first housing portion 31 a into which the base block 51 (see FIG. 8) of the runner member 50 is inserted from the side with respect to the door plate 40, and a damper member 32. The second accommodating portion 31b inserted from above with respect to the door plate 40, and a through-hole 31c that partially penetrates between the first accommodating portion 31a and the second accommodating portion 31b and extends along the vertical direction with respect to the door plate 40. And. The door plate attachment member 31 is embedded and fixed in a notch portion 42 formed at the upper end of the other door plate 40 (for example, the door bottom side), and a metal material (for example, zinc alloy) is molded (for example, die casting). Formed.

  The runner member 50 is connected to the base block 51 that is inserted and fixed from the side into the first housing portion 31a of the door plate mounting member 31 via the connecting portion that is pivotally supported by the base block 51. And a guide roller 52.

  As shown in FIGS. 6 and 7, the damper member 32 includes a damper cap member 33 and a direct acting damper 34 that is inserted into the damper cap member 33 from below and fixed.

  The damper cap member 33 has an opening below, and further has an elastic arm portion 33a having a free end below. The damper cap member 33 is formed by molding a resin material (for example, polyacetal (POM)). The elastic arm portion 33a is configured to be deformable with the lower end as a free end even when the linear motion type damper 34 is inserted and fixed. The elastic arm portion 33a includes a first projecting portion 33b that protrudes outward in the lateral direction. The second projection 33c is located below the door plate 40 from the first projection 33b and projects outward in the lateral direction. The first protrusion 33b and the second protrusion 33c of the elastic arm portion 33a penetrate the door plate attachment member 31 when the damper member 32 is inserted into the second housing portion 31b of the door plate attachment member 31. It is configured to be inserted into the mouth 31c and to be movable along the through-hole 31c.

  The direct acting damper 34 includes a return spring (not shown), a piston rod 34a, a piston (not shown) connected to the piston rod 34a, and an oil pressure chamber (not shown) pressed by the piston. A soft absorber mainly composed of a single hole or a multi-hole orifice (not shown) provided in the pressure chamber, absorbs an impact applied through the piston rod 34a and gradually pushes back the piston rod 34a. Acts as follows.

  In the opening below the damper cap member 33, the direct acting damper 34 is inserted and fixed from the top 34b opposite to the piston rod 34a, whereby the damper member 33 is configured.

  When such a damper member 33 is inserted and pushed into the second accommodating portion 31b of the door plate mounting member 31 from above with respect to the door plate 40, the tip of the piston rod 34a of the damper member 32 is the bottom surface of the second accommodating portion 31b. The linear motion type damper 34 is actuated in contact with. Furthermore, the first protrusion 33b and the second protrusion 33c of the elastic arm 33a are inserted into the through-hole 31c of the door plate attachment member 31, and the first protrusion 33b contacts the upper end 31d of the through-hole 31c. When the first protrusion 33b moves upward beyond the upper end 31d of the through-hole 31c, the spring-up suppressing device is released from the locked state.

  FIG. 8 illustrates the operation of the bounce suppression device of the present embodiment at the time of hanging the sliding door.

  First, the door plate attachment member 31 on which neither the runner member 50 nor the damper member 33 is mounted is embedded in a notch portion 42 formed at the upper end portion of the door plate 40 and fixed with wood screws 35 and 36 or the like.

  Next, as shown in FIG. 8A, the damper member 32 is inserted into the second accommodating portion 31 b of the door plate attachment member 31 from the upper side with respect to the door plate 40. In this case, the damper member 32 is pushed in while pressing the side surface of the elastic arm portion 33a so that the most protruding second protrusion portion 33c of the elastic arm portion 33a is guided into the opening of the second accommodating portion 31b. go. At this time, the opening edge 31e of the second accommodating portion 31b is chamfered to an inclined surface or a rounded surface so that the second projecting portion 33c can smoothly enter the second accommodating portion 31b. It is desirable to keep it.

  As shown in FIG. 8B, when the second protrusion 33c is further pushed into the inside from the opening of the second housing portion 31b, the elastic arm portion 33a is greatly deformed and the inner wall of the second housing portion 31b Slide down to go down.

  When the damper member 32 is further pushed in against the repulsive force of the direct acting damper 34, first the second protrusion 33c and then the first protrusion 33b are connected to the second storage part 31b and the first storage part. The upper end 31d of the through-hole 31c between the part 31a passes from above. Since the repulsive force of the direct acting damper 34 is applied, the first protrusion 33b is locked to the upper end 31d of the through-hole 31c, and the damper member 32 does not extend upward. FIG. 8C shows this state, that is, the locked state of the jump-up suppressing device.

  Next, as shown in FIG. 8 (D), the base block 51 of the runner member 50 with the guide roller 52 inserted through the upper rail 10 is moved to the first housing portion of the door plate attachment member 31 of the jumping suppression device in this locked state. Insert into the side 31a from the side. As a result, the second protrusion 33c is pressed against the side surface of the base block 51, and the elastic arm 33a is deformed.

  Next, as shown in FIG. 8E, when the base block 51 of the runner member 50 is further inserted and fixed, the deformation of the elastic arm portion 33a further proceeds, and the first protrusion 33b becomes the upper end 31d of the through-hole 31c. The damper member 32 extends upward by the repulsive force of the direct acting damper 34, and the locked state is released. When the damper member 32 extends upward, the upper end of the damper member 32 abuts on the lower end of the upper rail 10 or the gap between the two becomes very small, so even if an excessive force is applied during the soft closing operation, It is possible to reliably prevent the sliding door from jumping up. In the unlocked state, the second protrusion 33c is locked to the upper end 31d of the through hole 31c, so that the amount of protrusion of the damper member 32 is kept below a predetermined value, for example, 11 mm or less. In the modified mode, a protrusion is provided on the side surface of the base block of the runner member, and when the base block is further inserted and fixed, this protrusion also directly presses the first protrusion 33b to unlock. Is possible.

  As described above, according to the present embodiment, the damper member 32 does not extend in a locked state when the runner member 50 is not inserted into the first accommodating portion 31a of the door plate attachment member 31, When the member 50 is inserted into the first accommodating portion 31a, the member 50 is unlocked and extends in the direction of the upper rail 10. After hanging the sliding door, the damper member 32 is in an unlocked state. In this unlocked state, the damper member 32 extends to contact the upper rail 10 or there is a gap with the upper rail 10. Therefore, even if an excessive force is applied during soft closing, the door plate 40 can be effectively prevented from jumping up. Further, unlike the prior art, the soft closing stroke is not reduced. In particular, since the damper member 32 extends in the vertical direction of the door plate 40 to make contact with the upper rail 10 or adjust the gap, one end portion of the door plate 40 in the opening / closing direction (for example, door) If this bounce suppression device 30 is provided on the bottom side), and a conventional conventional bounce suppression mechanism 27 is provided on the other end of the door plate 40 in the opening and closing direction (for example, the door tip side), the sliding door moves in any direction. In this case, the sliding door can be prevented from jumping up. In addition, when the sliding door is suspended, the damper member 32 does not extend until the runner member 50 is inserted into the first accommodating portion 31a, so that the damper member 32 protrudes and the sliding door is suspended. The damper member 32 does not come into contact with the upper rail 10 and can be easily hung in the same manner as a normal sliding door. Moreover, since it is not necessary to lift the sliding door while shrinking the damper member 32 during suspension, there is also an effect that suspension can be performed with a small force. Further, since the jumping suppression device 30 only needs to be provided at the upper end portion of the door plate 40, it can be applied not only to the upper suspension type sliding door but also to the lower load type sliding door.

  In the present embodiment, the bounce suppression device 30 according to the present invention is provided on the door bottom side of the door plate 40 and the bounce suppression mechanism 27 according to the prior art is provided on the door tip side of the door plate 40. However, the bounce suppression device according to the present invention is provided. Of course, the apparatus 30 may be provided on both the door end side and the door bottom side of the door plate 40.

  All the embodiments described above are illustrative of the present invention and are not intended to be limiting, and the present invention can be implemented in other various modifications and changes. Therefore, the scope of the present invention is defined only by the claims and their equivalents.
