A sliding door including a hanging means for forming a body and a lower roller provided on a portion of the lower part of the door body on the door end side and rotatably mounted on the lower rail member. The apparatus is characterized in that there are a plurality of the lower rollers.

As described above, in the sliding door device according to the present invention, the number of lower rollers provided on the door tail side portion in the lower part of the door body and rotatably mounted on the lower rail member is the above-mentioned conventional sliding door. It is not one like a device, but a plurality.

Therefore, the load of the door body acting on the lower roller is distributed by the plurality of lower rollers.

As described above, according to the present invention, the load of the door body applied to the lower roller of the sliding door device can be dispersed.

In the present invention, the plurality of lower rollers may be arranged side by side with a small interval or a larger interval in the opening / closing movement direction of the door body, for example, at a small interval in the thickness direction of the door body or It may be arranged side by side with a larger interval than this.

In the former case, the number of lower rail members may be one, and a plurality of lower rollers may be rotatably mounted on the one lower rail member.

On the other hand, in the latter case, the number of lower rail members may be a plurality of, and one lower roller may be rotatably mounted on each lower rail member.

Further, in the latter case, the number of lower rail members may be a plurality of, and a plurality of lower rollers may be rotatably mounted on each lower rail member. For example, two lower rollers are rotatably placed on each of two rail members arranged side by side with a small interval or a larger interval in the thickness direction of the door body. The two lower rollers on the front side are arranged side by side in the thickness direction of the door body, and the two lower rollers on the door end side are arranged side by side in the thickness direction of the door body. You may do it.

In the present invention, all of the plurality of lower rollers may or may not have the same diameter dimension.

According to the latter case, the door forming the frame portion on the door tail side of the part on the door tail side of the door body when it is closed and moved to the fully closed position and the opening frame of the opening opened and closed by this door body. The width dimension of the overlapping portion with the vertical frame member on the buttock side (in other words, the dimension in the left-right direction which is the opening / closing movement direction) can be reduced, and the width dimension of the door body can be reduced accordingly. This makes it possible to increase the width dimension of the opening when the door body is opened and moved to the fully opened position.

In the latter case (when not all of the plurality of lower rollers have the same diameter dimension), as described above, the plurality of lower rollers have a small interval in the opening / closing movement direction of the door body or this. When the lower rail members are arranged side by side with a larger space and the number of lower rail members is one, and a plurality of lower rollers are rotatably mounted on this one lower rail member. Of the plurality of lower rollers, it is preferable that the diameter dimension of the lower roller arranged on the door end side is larger than the diameter dimension of the other lower rollers.

Further, in the latter case (when not all of the plurality of lower rollers have the same diameter dimension), as described above, the plurality of lower rollers are closely spaced in the thickness direction of the door body. Or, when the lower rail members are arranged side by side with a larger interval and the number of lower rail members is multiple, and a plurality of lower rollers are rotatably mounted on each lower rail member. Of the plurality of lower rollers mounted on each lower rail member, the diameter dimension of the lower roller arranged on the door end side may be larger than the diameter dimension of the other lower rollers. preferable.

In the present invention, as described above, when not all of the plurality of lower rollers have the same diameter dimension, the height positions of the rotation center axes of the plurality of lower rollers are the same. May or may not be.

In the former case, the plurality of lower rollers are formed between two flange portions provided on both sides in the roller thickness direction, which is the thickness direction of the door body, and these flange portions. It shall have a groove, and the depth dimension of the groove portion of the lower roller arranged on the door end side having the largest diameter dimension as described above shall be larger than the depth dimension of the groove portion of the other lower rollers. Is preferable.

In the present invention, a door stop member may or may not be provided at a position on the door tail side of the upper rail member on the door tail side with respect to the door body that has been opened and moved to the fully open position. good.

In the former case, the door body opens and moves at high speed while receiving a large external force in the moving direction, and when the door body that opens and moves to the fully opened position comes into contact with the door stop member, the door body swings (door). The upper part of the body moves away from the door stop member, and the lower part of the door body swings so as to approach the door stop member), and a lifting force is generated from the lower rail member with respect to the lower roller, so that the lower roller is the lower rail member. There is a risk of coming off (in other words, derailing).

However, as described above, the door body is opened by setting the diameter dimension of the lower roller arranged on the door end side of the plurality of lower rollers to be larger than the diameter dimension of the other lower rollers. Even if this door body that opens and moves at high speed while receiving a large external force in the moving direction and opens and moves to the fully open position comes into contact with the door stop member, the door body swings (the upper part of the door body moves away from the door stop member). At the same time, it becomes possible to prevent the lower part of the door body from swinging so as to approach the door stop member). As a result, it is possible to suppress the generation of a lifting force from the lower rail member with respect to the lower roller, and it is possible to prevent the lower roller from coming off the lower rail member.

The effect of preventing the lower rail from coming off is that the height positions of the rotation center axes of the plurality of lower rollers are the same, and the plurality of lower rollers have the roller thickness in the thickness direction of the door body. It is assumed that it has two flange portions provided on both sides in the longitudinal direction and a groove portion formed between these flange portions, and the groove portion of the lower roller arranged on the door end side having the largest diameter dimension. By making the depth dimension of the lower roller larger than the depth dimension of the groove portion of the other lower roller, it becomes larger.

In the present invention, a lateral slip prevention means for preventing a plurality of lower rollers from laterally shifting in the thickness direction of the door body with respect to the lower rail member may be provided at the lower portion of the door body. You may.

In the former case, the form and structure of the lateral slip prevention means may be arbitrary. For example, if the bracket that rotatably supports the lower roller has two flanges arranged on both sides in the thickness direction of the door body from the arrangement of the lower roller, the lateral slip prevention means is For example, when a plurality of lower rollers are provided on the inner surface of one of the two flange portions facing the lower rail member and try to laterally shift in the thickness direction of the door body with respect to the lower rail member. In addition, it may be a contact portion that comes into contact with the lower rail member.

Here, the number of abutting portions forming the lateral displacement preventing means is arbitrary, and may be, for example, one or a plurality.

In the latter case, the plurality of contact portions may be provided at arbitrary locations.

As described above, when not all of the plurality of lower rollers have the same diameter dimension, the diameter dimension of the lower roller arranged closest to the door end is the diameter of the other lower rollers. If it is larger than the dimension, the door body can be opened and closed from at least the position of the lower roller having the largest diameter dimension arranged on the door tail side on the inner surface facing the lower rail member in one flange portion. It is preferable to provide them at positions separated from each other on both sides in the moving direction.

This is because, as described above, in the present invention, the diameter dimension of the lower roller arranged on the door end side is larger than the diameter dimension of the other lower rollers, thereby preventing the lower rail from derailing. Is placed on the door end side most, and the lower roller with a large diameter that can prevent derailment is prevented from laterally shifting to the lower rail member in the thickness direction of the door body. Because it is the most important to do.

In the present invention, the contact portion forming the lateral slip prevention means may be integrated with one flange portion or is separate from one flange portion, that is, one flange portion. It may be a contact member fastened to the inner surface facing the lower rail member in the above by a fastener.

The door closing device 55 closes and moves due to the pulling force of the long-sized coil spring and the pulling force of the wire 51 of the automatic closing device 50. When the locking member 55B reaches near the movement limit position on the closed side, in other words, when the door body 1 approaches the fully closed position, the moving speed of the locking member 55B decreases due to the action of the damper described above. , The door body 1 reaches the fully closed position while reducing the closing movement speed.

Further, when the door body 1 that has reached the fully closed position is opened and moved by the hand holding the grip portion 40, the door body 1 and the locking member 55B move due to the action of the check valve provided on the damper. When the locking member 55B reaches the above-mentioned movement limit position on the opening side while accumulating a tensile force on the long coil spring, the locking member 55B is guided to move. Due to the action of the guide groove formed in the above-mentioned guide member, the locking member 55B swings in the direction opposite to the above-mentioned, and therefore, the operating member 56 locked to the locking member 55B is this. It separates from the locking member 55B, whereby the door body 1 separates from the door closing device 55 and reaches an opening position such as a fully open position.
