The reinforcing portion 34f is formed in a substantially triangular piece shape so as to connect a portion extending from the base portion 34a to the fitting portion 34d and the contact portion 34e.
According to the illustrated example, two reinforcing portions 34f are provided, but may be one or three or more.
The reinforcing portion 34f has a portion that extends from the base portion 34a to the fitting portion 34d and a contact portion 34e so that the base portion 34a side is not shifted or deformed downward, in the sliding door thickness direction, the door tip direction, or the like. Connected.

Next, an assembling procedure of the main part of the buffer structure in the above-described suspended suspension door device 1 will be described in detail.
First, as shown in FIG. 2, the corner cushioning member 34 is attached to the lower end side portion of the door tip portion of the sliding door main body 31 from the lower side.
At this time, the abutting portion 34e and the fitting portion 34d of the corner cushioning member 34 are inserted into the lateral concave groove 31b at the lower end of the sliding door body 31, and the inner side surfaces of the rising pieces 34b, 34b of the corner cushioning member 34 However, it contacts or approaches the front and back surfaces of the sliding door body 31.

  Then, the fastening tool 34g is inserted into the through hole 34e1 provided in the contact part 34e, and the tip of the fastening tool 34g is screwed and connected to the bottom part 31a2 of the vertical groove 31a.

Next, the door cushioning member 33 is attached to the door end portion of the sliding door main body 31.
At this time, the recessed engagement portions 33c1 and 33c1 of the door stop buffer member 33 are fitted to the engaged piece portions 31a1 and 31a1 on the door end side of the sliding door main body 31 from the upper side, respectively. 33 is slid downward.

  The door stopper buffer 33 slid downward is positioned by being received by the base 34 a of the sliding door body 31. At this time, the protruding piece 34 c of the corner cushioning member 34 is inserted into the lower end side of the door cushioning member 33.

Therefore, according to the upper suspension type sliding door device 1 having the above-described configuration, the sliding door 30 automatically moves in the closing direction along the inclined rail 20 when the closing operation is performed, and the gap with the floor surface F is gradually increased. Narrow to.
Even if the sliding door 30 comes into contact with an object or the like near the floor during the closing operation, the impact on the object or the like can be reduced by the elastic deformation of the door cushioning member 33 and the corner cushioning member 34. .

  Moreover, the corner cushioning member 34 is displaced on both sides in the thickness direction of the sliding door main body 31 due to the contact with the object or the like. The rising pieces 34b, 34b, the fitting part 34d that fits into the sliding door main body 31, the fastening structure by the contact part 34e, the reinforcing structure by the reinforcing part 34f, and the like can be effectively blocked.

  Further, when contacting with the object or the like, the lower end side of the door cushioning member 33 is flexibly elastically formed by the gap c1 in the sliding door opening / closing direction and the gaps c2 and c2 in the sliding door thickness direction in the door cushioning member 33. Since it can be deformed, an impact on an object or the like can be effectively mitigated.

  The above-described suspended sliding door device 1 includes a mechanism (not shown) that electrically opens the sliding door 30 as necessary, a damper mechanism (not shown) that reduces the closing speed of the sliding door 30, and a sliding door. You may make it provide the locking mechanism etc. which lock 30 in the fully-closed state, the latching mechanism which maintains 30 in a fully open state, and the like.

Further, according to the illustration of FIG. 2, the corner cushioning member 34 is attached to the lower end side corner portion of the sliding door main body 31 from the lower side, but as another assembling method, the lower end side of the sliding door main body 31 is used. The corner cushioning member 34 can be attached to the corner portion from the door end direction side.
For example, when the corner cushioning member 34 is replaced by maintenance work or the like, the door cushioning member 33 is slid upward with respect to the sliding door main body 31, and then the fastener 34g and the corner cushioning member 34 are moved in the direction of the door. It is possible to attach the new corner cushioning member 34 from the door end direction side, and the workability thereof is good.

  In addition, according to the above-described suspension type sliding door device 1, the corner cushioning member 34 is provided at the corner portion on the lower end side on the door tip side in the sliding door 30. As another example, the lower end side on the door bottom side in the sliding door 30. A corner cushioning member 34 may be provided in the corner portion so that when the sliding door 30 opens, the impact when the lower corner portion on the door bottom side of the sliding door 30 abuts against an object or the like may be alleviated. .

  Further, according to the above-described upper suspension type sliding door device 1, the corner cushioning member 34 is provided for the sliding door 30 suspended from the inclined rail 20, but as another example, the corner suspension member 34 is suspended from a substantially horizontal rail (not shown). The corner cushioning member 34 may be provided on the sliding door 30 in the same manner as described above.

  Moreover, according to the said embodiment, although the corner buffer member 34 was provided with respect to the sliding door 30 of the upper suspension type sliding door apparatus 1, the said corner buffer member 34 is a sliding door which opens and closes while contacting a floor surface. It is also possible to provide the lower end side corner portion, the lower end side corner portion of the folding door, or the like.

It is a front view which shows an example of the upper suspension type sliding door apparatus which concerns on this invention. It is a principal part disassembled perspective view of a sliding door. It is the (III)-(III) sectional view taken on the line in FIG. It is a principal part notch enlarged view of a sliding door.
