Description

  The present invention relates to a sliding door device, and in particular, a sliding door device provided with a sliding door disposed at an entrance and a traveling rail that mounts traveling wheels attached to a door tip side and a door bottom side of a sliding door and suspends the sliding door. It is about.

8 to 10 show a smoke-proof sliding door device 50 as an example of a conventional sliding door device (see Patent Document 1).
The smoke-proof sliding door device 50 includes a sliding door frame member 51, a sliding door running rail 54 that guides the transition of hanging the sliding door 53, and a running wheel 56 that is placed on the rail 54.

  The rail 54 is bent in a U shape in cross section to form a guide portion 55, and its tip 55 b is used as a tread surface of the traveling wheel 56. The traveling wheel 56 is a grooved wheel that can be placed on the tread surface. The traveling wheel 56 is swingably attached to an attachment arm 57 and attached to the sliding door 53 via the attachment arm 57.

  While the sliding door 53 normally forms a slight gap between the frame member 51 and the sliding door 53, in the closed position, the sliding door 53 is framed by a guide roller 59 that rolls and presses the side surface of the mounting arm 57. The member 51 is pressed and sealed to obtain a sealing effect such as smoke shielding.

  As a result, when the sliding door is opened and closed, the traveling wheel 56 moves along the guide portion 55 of the rail 54 and, when reaching the closed position, guides the side surface of the mounting arm 57 that pivotally supports the sliding door 53 so that it can swing. It is pressed by the roller 59 and the sliding door 53 is brought into close contact with the airtight holding packing P in the direction of the frame member 51 to block the passage of smoke.

  However, the smoke-proof sliding door device 50 does not consider the smoke shielding on the lower side of the sliding door. For example, when a fire breaks down in a building or the like, smoke enters from the lower part of the sliding door. There is a problem that sufficient smoke shielding is not possible, and the sliding door is swingably mounted. Therefore, when the normal sliding door 53 is opened and closed, the sliding door 53 moves in the opposite direction to the frame member 51 by the notch 58 of the mounting arm 57. However, there is a problem that the sliding door 53 and the packing P are in contact with each other and cannot be smoothly opened and closed.

  For this reason, using a square bar for the rail, a curved portion is formed so that the traveling wheel moves to the wall side at the closed position of the sliding door, and the traveling wheel of the sliding door having the V-shaped groove traveling wheel disposed on the upper portion is provided. There has been proposed a sliding door device that is placed on the rail and in which the sliding door comes into close contact with the opening portion on the wall side in accordance with the curved portion of the rail in the closed position (see Patent Document 2).

  As shown in FIGS. 11 to 12, the sliding door device 60 includes a sliding door 61 for opening and closing the opening 63, a rail 66 having a rhombus cross section laid on a wall 62 above the opening 63 via a bracket 67, It consists of a traveling wheel 64 attached via an angle 65 disposed on the upper part of the sliding door 61 placed on the rail 66.

  The rail 66 forms curved portions 66 a and 66 b on the door end side and the door bottom side at the position where the sliding door 61 closes the opening 63. A bridge 66c for allowing passage of a door-end side traveling wheel 64a, which will be described later, is arranged on the curved portion 66b on the door bottom side. On the other hand, the traveling wheel 64 includes a door end side traveling wheel 64a and a door bottom side traveling wheel 64b, and both traveling wheels 64 form a V-shaped groove that travels along the rail 66, as shown in FIG. The outer inclined surface (on the side opposite to the wall 62) of the door-side traveling wheel 64b is configured to be shorter than the width of the inclined surface of the rail 66, and the entire sliding door 61 is formed along the curved portion 66b without riding on the bridge 66c. Move only L to the side.

  In the above configuration, when the sliding door 61 moves from the open position to the closed position, the V-shaped groove of the door-end side traveling wheel 64a passes through the curved portion 66b on the door bottom side without shifting to the wall 62 side by the bridge 66c. Then, it reaches the curved portion 66a on the door end side and shifts by L to the wall side. When the door-end traveling wheel 64a reaches the door-end side curved portion 66a, the door-end traveling wheel 64b also reaches the door-end-side curved portion 66b at the same time. Just migrate.

  As a result, the sliding door 61 is brought into contact with the packing P, and the sliding door 61 can ensure airtightness inside the opening 63.

However, in this sliding door device, the amount of movement at the closed position of the sliding door is restricted to less than half of the rail width, and it is difficult to adjust when installing the sliding door, and it takes time to process the curved portion formed on the rail, In addition, despite the fact that the traveling wheels have similar shapes, there is a problem that not only the number of parts is increased, but also they are easily misunderstood because they need to be changed on the door end side and the door bottom side.
Japanese Utility Model Publication No. 61-17166 JP-A-61-113982

In view of the problems of the above-described conventional sliding door device, the present invention is easy to process the rail, can sufficiently secure the moving amount in the closed position of the sliding door, and easily adjust when the sliding door is attached. An object of the present invention is to provide a sliding door device that can be used.
It is another object of the present invention to provide a sliding door device that allows the sliding door to travel in a stable posture even when the door width and the door pocket width are extremely small.

  In order to achieve the above object, the sliding door device of the present invention includes a sliding door disposed at the doorway, a traveling rail that mounts traveling wheels attached to the door end side and the door bottom side of the upper sliding door, and suspends the sliding door. In the sliding door device having the above structure, the door bottom side traveling wheel is disposed so as to be able to advance and retract from the sliding door in the longitudinal direction of the traveling rail.

  In this case, the door bottom side traveling wheel can be disposed so as to be able to advance and retract from the sliding door by a slide rail.

  Further, the traveling rail can be bent to the wall side at the position where the traveling wheels attached to the door end side and the door bottom side are located at the closed position of the sliding door.

  In addition, the traveling wheel can be swingably attached along the bending of the traveling rail.

According to the sliding door device of the present invention, since the door-side traveling wheels are arranged so as to be able to advance and retreat in the longitudinal direction of the traveling rail from the sliding door, the processing of the rail is simple, and the amount of movement in the closed position of the sliding door Can be secured sufficiently, and adjustment at the time of mounting the sliding door can be easily performed.
Further, even when the door width and the door pocket width are extremely small, the sliding door can be run with a stable posture when opening and closing.

  Further, the door-side traveling wheels can be smoothly advanced and retracted by arranging the door-side traveling wheels so that they can be advanced and retracted from the sliding doors by slide rails.

  In addition, the door-side traveling wheel protrudes backward from the sliding door at the closed position by bending the rail position for traveling where the traveling wheels attached to the door end side and the door-end side are located at the closed position of the sliding door. In this position, it is guided by the bent part on the door bottom side of the traveling rail and moves to the wall side, and the door side traveling wheel does not travel to the bent part on the door bottom side of the traveling rail at the open position of the sliding door, Since one traveling rail can be provided with bent portions at two locations, a sufficient amount of movement at the closed position of the sliding door can be secured, and adjustment at the time of mounting the sliding door can be easily performed.

  In addition, by attaching the traveling wheel so as to be able to swing along the bending of the traveling rail, the traveling rail and the traveling wheel can be kept in the same direction even at the bent portion of the traveling rail. Runs smoothly without being caught by the running rail.

  Embodiments of the sliding door device of the present invention will be described below with reference to the drawings.

1 to 4 show an embodiment of the sliding door device of the present invention.
The sliding door device 1 includes a sliding door frame member 6, a sliding door 5 housed in a door bag 6a formed on one side of the sliding door frame member 6, a traveling rail 2 that suspends the sliding door 5 and guides the transition. Is provided. The sliding door 5 is configured so that the traveling wheels 4 a and 4 b are attached to the front and rear of the upper part via attachment arms 42.

  The traveling rail 2 includes an L-shaped flange 21 that is attached to the sliding door frame member 6 and a guide portion 22 that is mounted on the horizontal surface of the flange 21 and on which the flanged groove 41 of the traveling wheels 4a and 4b is placed. The traveling rail 2 is attached so as to be inclined toward the closed side so that the sliding door 5 is always kept in the closed position by its own gravity.

  The guide portion 22 of the traveling rail 2 forms bent portions 22a and 22b that bend the portions where the traveling wheels 4a and 4b attached to the door end side and the door bottom side are located at the closed position of the sliding door 5 to the wall side. is doing. The traveling wheels 4a, 4b travel by the gravity of the sliding door 5 and are guided by the bent portions 22a, 22b to move to the wall side. The sliding door 5 is used as a sealing material (not shown) formed on the frame member 6. Adhere closely to ensure airtightness.

  The traveling wheels 4 a and 4 b are attached to the door end side and the door bottom side of the sliding door 5. The traveling wheel 4a on the door end side has a lower surface of the mounting arm 42 having a U-shaped cross section fixed to an appropriate position on the upper surface of the sliding door 5 with fixing means such as a bolt, and a flanged groove 41 is mounted on the upper surface of the mounting arm 42. A mounting bracket 44 having an inverted L-shaped cross section, which is rotatably disposed, is mounted via a bearing 43, and the running wheel 4 b on the door bottom side has the lower surface of the mounting arm 42 and the inner member of the slide rail 3 on both inner side surfaces. It is attached to a mounting member 34 having a U-shaped cross section in which 31 is disposed. The inner member 31 is a ball 35 attached to the inner surface of the outer member 32 by a ball retainer 36 on the outer member 32 of the slide rail 3 attached via a reinforcing member 33 disposed at a proper position on the upper door bottom side of the sliding door 5. Install it slidably in contact with. The configuration of the flanged groove 41 attached to the upper surface of the mounting arm 42 of the door-side traveling wheel 4b is the same as that of the door-side traveling wheel 4a.

  The flanged groove wheel 41 includes a sliding surface 41a slightly larger than the width of the guide portion 22 of the traveling rail 2 and a flange 41b formed so as to sandwich the sliding surface 41a. Move without having to. Further, since the mounting bracket 44 for rotatably mounting the flanged groove 41 is attached to the upper surface of the mounting arm 42 via a bearing, the flanged groove 41 is a bent portion formed in the guide portion 22 of the traveling rail 2. Guided by 22a and 22b, it swings and no excessive load is applied to the flanged groove wheel 41.

  Since the running wheel 4b on the door butt side is attached to the door butt side of the sliding door 5 by the slide rail 3, when the sliding door 5 is in the closed position, the position shown by the solid line in FIG. Further, when the sliding door 5 is in the fully open position, the sliding door 5 is moved to the sliding door 5 side as shown by a one-dot chain line in FIG.

  1A, when the sliding door 5 is in the closed position, the door-side traveling wheel 4a is positioned on the bent portion 22a of the guide portion 22 and the door-side traveling wheel. 4 b is located on the bending part 22 b of the guide part 22. As a result, the sliding door 5 moves to the wall side and comes into close contact with a sealing material (not shown) formed on the opposing surface of the frame member 6. When the sliding door 5 is on its way from the fully open position toward the closing side, the sliding door 5 is driven while the slide rail 3 supported by the bearing is pulled out. After the rail 3 reaches the limit of protrusion, the front and rear wheels 4a and 4b are guided to the bent portions 22a and 22b.

  When the sliding door 5 moves to the right side in FIG. 1 and moves to the open position, the door-side traveling wheel 4 a moves with the transition of the sliding door 5, and the door-side traveling wheel 4 b is moved by the slide rail 3.
